Rotating stage was entirely built around the central column surrounded by conical tread stairs.Then they turned into a tight curve is a space-saving solution, as another floor to continue to provide access to an area of significantly reduced compared with traditional stairs.
In the Middle Ages, the spiral staircase is a general circular castle in the tower, and often in the stone. It is set in a clockwise agreed to the judge to hand with a knife attack further disadvantage.
These days, spiral staircase design and development of substantial savings in space, while protecting their interests in a variety of materials such as glass and stainless steel. Now they have the right to property offers a wonderful selection criteria of the stairs, after a fashion function room.
Because of their rigid construction, it is not too much, the elderly or the disabled easy to use and move between the floors can be difficult for large pieces of furniture. For security reasons, there are several rules and regulations of the size of the spiral staircase installed in the new version and installed in residential and commercial decoration.
UK Building Regulations
Spiral staircase have their own British Standard specializes in them - the first BS 5395 Part 2. The BS is part of K in the Building Regulations and a large spiral staircase for a particular application to ensure that enough.
In the document, the spiral is divided into five classes, A and E for the secondary internal screw is a large automatic exposure spiral completely open. Each category will have a decision between the rise (the ratio between the height of each step) and after (the depth of each step) and the clear tread width (the distance from the center armrest column) for the spiral's application requirements requirements. In general, the more people in the spiral of large diameter smaller increase in height, making it more secure, more comfortable about climbing.
China-made spiral staircase
Since there are two rules of general internal screw, stick with - should not exist between the tracks or over 100 mm gap between the railings, railing to climb construction.
A and B of BS 5395 dealing with the measurement requirements of internal spiral staircase. A class is known as the secondary internal spiral staircase and B-class, mainly for residential use of a spiral.
In a clear spiral pattern in secondary schools should be 600 mm wide (in a particular model or design may be) will give a diameter of 1450 mm with regard to the center of both columns and railings. Each step height should be no longer than 220 mm, the center will be at least 145. A spiral staircase as the head must have a clear tread width of 800 mm (1800 mm in diameter) and 220 mm and 190 mm maximum increase to the minimum center. In general, a spiral floor opening about 100 mm in diameter as the opening is a square / rectangular or round in size. For example, should a 1600 mm diameter of the screw has a diameter of 1700 mm square or opened. This is a 50 mm a common gap between the handrail and the floor edge / both sides of the wall boundary. Spiral staircase at the highest level, usually a step in the center to extend the edge of the floor to join. It is sometimes the shape of the top lifting platform slightly smaller to make.
Commercial spiral staircases
Category BS5395 Chief Executive under commercial stairs - the needs of the public. The guide to ensure that people who are not familiar with the spiral can safely use. And all the commercial spiral staircase is a central pillar handrail requirements and the rest of the platform, as the composition of the fly more than 16 risers.
C class is less than half the public staircase, and there is no more than 220 mm increase in length and width of 800 mm tread clear. This (with the arm in the middle column), so around 1900, 2000mm diameter. Class D is a semi-public service with more than 50 stairs. The regulation of 一九 ○ 毫米 find the lowest increase, with 900 mm (2100 mm in diameter) clear tread.
Class E helix transactions intended to be used with a large number of people at the same time - shopping, soccer, such as stadiums. A clear need for the tread width of 1,000 mm and a 190 mm to 250 mm maximum and minimum rise along the measurement.
Covered by BS5395 standards and interpretation of the planning office is not always static.Sometimes a relaxing, for example, one to the existing vicious cycle, respectively.
Summary
Property, spiral staircase offers a great solution, go to a summit. There are many different models, there are many ready-made large, ready-made solution kits imported from Europe and the United Kingdom. If you are looking for installation / purchase of the spiral, it is important that the investigation into British Standards suppliers. If in doubt, go with your building control officer.
Floor to floor height will determine the quantity needed, the total amount of the crawler run the stairs, climb it (4 '- 0 ", 4" - 6 ", 5' - 0", 5'1 "and 6" - 0 "30 ° helix turn of every stage, 5'7 'tread coil turn 28 degrees). Since we planned to have the best access to the known total rotation of the upper and lower layer of the location and direction of the stairs. We checked, there will be enough in all areas of the spiral space.
Precision Pine will send a confirmation to the customer before producing the final version of the program.
Programs and other materials and the time required: General Settings, the following instruments and other materials:
Tools: a wood saw (electric miter saw is ideal), hack saws, hammers, no. 2 square drive screwdriver or drill driver, key (a / 2 "and 9 / 16" Point, 1 / 4 "and 3 / 4" closed, one 1-1/2 "and 1-3 / 8" opening wrench and a medium-size or larger pipe pliers, keys, two control), includes pliers, drill with 1 / 8 ", 3 / 16", 1 / 4 ", 3 / 8" bit (9 / 16 ", 1 / 2 "and 1" diameter), 24 "bar clamp, two 6" C - Clamp, two 3 "spring from. Additional races are always useful.
You may need more or less woodworking tools, depending on your experience, special equipment, floor structure and design, and / or the design of future improvements in the standard package itself.
Material: 2 times handrail at the top of the temporary support and temporary support 1X wood timber.
The kits of the General Assembly is easy. Carpentry skills and tools at least general knowledge is required. Many of our owners of the screw to install. Some people feel more comfortable with an experienced carpenter to work to complete. At least two people at the steps to install on the scene.
Time these steps to build will vary depending on the speed of installation (whether experienced or not) the size, height and / or the complexity of the stairs, and obstacles (walls and spiral around the amount that usually takes longer than Building on the spiral stairs). According handrail spiral galaxies will require more than the outside rail and railing installation.
As a general guideline standard, medium-sized small obstacle in the environment staircase takes about two days, people that one of the spiral before installing. No systematic experience with our carpenters to quickly work to do, but often need more time.
To save time, the installer should be read before the start of the work of the General Assembly of the manual. Precision required customers to send packages to send more than the Assembly's Guide service. We are here to answer any questions before the installation process.
Precision Pine meeting will send your kit and instructions for delivery. We strongly recommend that you and / or your installer read and understand the instructions, and try to take the steps to install. Installation work will be done quickly once the process of understanding.

Proposed gap spiral staircase: Precision for the proposed two-inch approval for any obstacles to the stairs. (For example, the 5 "- 4 square finished size of the upper floor of the opening of 5" - 4 "comfortably accommodates a 5" - 0 "diameter steps) is installed on the stairs a bit cramped. .Five "-1" specially designed coil can be placed in the 5 "- 4 five" - 4 "open." But if you're a smart spiral or a modern style, you might need a full open but at least 5 "- 6 '5" - 6 ".
Random thought: the need for sufficient headroom to allow for give you landed in the upper edge, as the landing ceiling. Precision plans 6 "- 6" minimum allowable form.
Positioning: Positioning the spiral from the top of the landing of the final size to finalize. Some of the top destination a little more time than necessary to provide, does not intend to have a significant hurdle.
Stairs should be positioned so that it does not interfere with the wall, door, windows, interior decoration materials, light switches, thermostats, sockets, etc. Remember that the recommended approval 2 "off the edge of the tread or 4 of all parts" of the whole. If you have a block closer to the stairs so we make recommendations to the appropriate location.
Floor to floor height: height from the ground to the ground floor of the lower surface of the vertical processing of the final products from the surface to the upper floor. Each staircase is set on the floor of the customer to meet floor height, so accurate measurement of the distance needed for the order. Important to see how the floor (wood finish, carpet, tile, etc.) can be added in a floor underlay. After completing a floor thickness can increase or decrease in the total floor to floor height.
Precision Pine will discuss with the client these issues and appropriate recommendations and on the floor to floor height. If you have a quote of approximately estimate the level of the floor to the ground, remember the top level of the system (usually the thickness of 10-1/2 to add "or more) to the ceiling height on lower level.
Trap Location: in which direction the stairs will be involved in the direction of the staircase, the best direction, down the stairs. Your floor to floor height will determine how big the pedal, so much shifted from the bottom of the stairs. As you climb the stairs right in your right arm. The left staircase railing will be on your left. Usually the stairs to a room in the open part of a clear entry and exit in an open area near them. When some customers may have east staircase, to strengthen the visual effect of low floor.
Tall, stacked spiral: spiral staircase kits can be ordered a word to fit in apartments, especially large units (usually 12 feet above the floor to floor dimensions) You may have permanent side support.Precision of the proposed customers and suppliers when necessary without any additional support costs.
