Description
Technical Field
The utility model belongs to the technical field of stair structure technique and specifically relates to arc steel construction stair.
Background
The building is used as a component for vertical traffic between floors. The method is used for traffic connection between floors and when the height difference is large. Stairways are also provided in multi-story and high-rise buildings provided with elevators and escalators as the main means of vertical transportation. High-rise buildings, although using elevators as the main vertical transport means, still need to keep staircases for escape in case of fire. The stairs are composed of continuous stair sections (also called stair runs), platforms (rest platforms), enclosing members and the like.
Present compound residence or compound building section, the structure sets up to two-layerly, connect from top to bottom through the stair, in order to improve the inside pleasing to the eye of house, generally can set stair into rotatory stair (overlook and be circular), however, because the inside structure diverse of house, if the inside space of house is the rectangle, if make circular stair with stair, will make the stair less, the effect is not good, if make sharp stair, not only aesthetic property is not good, moreover, occupy great space, the effect is also not good. In addition, the existing stairs generally do not have flame retardant performance, the stairs are used as connecting channels, if the stairs are burnt in a short time, the escape time of a user can be shortened, the rescue difficulty is increased, and moreover, if the stairs (particularly spiral stairs) made of stone materials are adopted, due to the fact that no support frame is arranged, the bearing performance is poor, and certain potential safety hazards exist.
Disclosure of Invention
Not enough to prior art, the utility model provides an arc steel construction stair to solve the problem that proposes among the above-mentioned background art.
The technical scheme of the utility model is that:
arc steel construction stair, its characterized in that: it includes stair main part and side board main part, the both ends fixedly connected with side board main part of stair main part, overlook after stair main part and the connection of side board main part and be duck egg molding arc stair, the inside of stair main part all is provided with strengthens the supporting layer, the inside of side board main part all is provided with fire-retardant layer, the interior outside surface of side board main part all coats and has white paint layer.
In order to achieve the best effect and the maximum utilization rate, the arc-shaped stair with the duck egg shape is adopted, the white paint coating is adopted on the side face of the arc-shaped stair, the color tone is increased, in the construction process, the artificial stone of the side panel main body is shaped by adopting the field hot bending process, and all splicing positions are polished, so that the whole stair cannot see a wire joint, and the arc-shaped stair is integrally white. The prominent effects are as follows: the arc is natural, can not see any interface, and the binding off is compact, and the rate of utilization is big.
Furthermore, the reinforcing support layer is a reinforcing steel bar support net layer. The stair body is mainly used for improving the bearing capacity of the stair body, so that the stair body is safer to use.
Further, the flame-retardant layer is a flame-retardant interlayer layer. The purpose is as follows: the flame retardant property of the stair is further improved, so that the stair is not easy to burn, and the escape time of a user can be prolonged when a fire disaster occurs.
Further, the white paint layer is a white latex paint layer. The purpose is as follows: and a white model is made, so that the color tone of the building is more consistent with the style of the house.
Further, the material of stair main part and side panel main part is white rostone. The purpose is as follows: and (5) making an integrated white model.
The utility model has the advantages that: the utility model discloses beat stair and cause figurative arc stair of duck egg, not only improve the rate of utilization widely, furthermore, the rostone of side board main part adopts the technology of on-the-spot hot bend to accomplish the molding, all concatenation departments adopt burnishing and polishing, make whole stair can not see a silk seam, white molding as an organic whole, and is more pleasing to the eye, the result of use preferred, furthermore, through being equipped with the enhancement supporting layer, further improve the bearing capacity of stair main part, make the use of stair main part safer, through being equipped with fire-retardant layer, further improve the fire behaviour of stair, make it be difficult to burnt, when the conflagration appears, the time that can prolong the user and flee, therefore, the clothes hanger is strong in practicability.
