Problems solved by technology

In this way, it not only leads to the problems of low construction efficiency and long construction period, but when using fireproof boards, since the lower end of the wall needs to be made into a dog-tooth shape that fits with the steps of the stairs, it will inevitably lead to waste of materials and increased construction costs.

Embodiment 1

[0024] Example 1, see figure 1 , a non-load-bearing fireproof partition wall for scissor stairs, which is used to isolate two stairs of a scissor ladder on the same floor, and has a cast-in-place reinforced concrete structure with a single-layer steel mesh 1.

[0025] Wherein, the steel mesh 1 adopts 8@200X200 two-way steel mesh sheets. In addition, the wall of the partition wall is poured with aluminum alloy formwork, and the thickness of the wall is ≤ 100mm; in addition, the wall of the partition wall is mounted on one of the scissor ladders, and the staircase with the partition wall has a widened section.

[0026] In this embodiment, the steel mesh 1 can also adopt any specification of 6@200X200, 6@300X300 and 8@300X300.

[0027] In this embodiment, since the partition wall is actually set according to the requirements stipulated in the fire protection code, it only needs to meet the functional requirements of fire protection for one hour, and only a 60mm thick concrete wa...

Embodiment 2

[0028] Example 2, combined with figure 1 , a scissors staircase, including two stairs of the scissors ladder and a partition wall 2 between the two stairs, the partition wall 2 is made of the non-load-bearing fireproof partition wall of embodiment 1.

[0029]Wherein, in the structure in which the partition wall 2 is carried on one of the stairs 3, the reinforcement mesh 1 is fixedly connected with the stair reinforcement or the stair reinforcement mesh of the staircase 3. The fixing method includes welding the steel bars of the two through the lap joint, or lap welding together with the help of steel plates, flat irons or round bars; it also includes binding and fixing them together with iron wires. The stairs 3 carrying the partition wall 2 and the partition wall 2 are poured synchronously using aluminum alloy formwork. And the scissors intersection of two described stairs is also provided with middle beam 4, and middle beam 4 forms the support to two stairs at the middle se...

Embodiment 3

[0030] Example 3, combined with figure 1 , a scissors staircase construction method, the non-load-bearing fireproof partition wall in the scissors staircase described in embodiment 1 is poured separately by using aluminum alloy formwork.

Abstract

The invention discloses a non-bearing fireproof partition wall for scissor stairs, the scissor stairs and a construction method of the scissor stairs. The partition wall is of a cast-in-place reinforced concrete structure with a single-layer reinforcing mesh, wherein the single-layer reinforcing mesh is a 8 @ 200 * 200 or similar bidirectional reinforcing mesh piece, and the thickness of the partition wall is smaller than or equal to 100mm; a wall body of the partition wall is carried on one stair of the scissor stairs, and the stair carrying the partition wall is provided with a widened section; the scissor stairs are provided with the partition wall, and in the structure that the partition wall is carried on one stair, the reinforcing mesh is fixedly connected with stair reinforcing steel bars or a stair reinforcing mesh; and in the construction method of the scissor stairs, the partition wall is poured through an aluminum alloy mold. The non-bearing fireproof partition wall has thebeneficial effects that the partition wall is good in structural stability, safe to use and long in service life; the scissor stairs adopting the partition wall have the same beneficial effects; and according to the stair construction method, the construction efficiency can be effectively improved, and the construction cost is saved.

Description

technical field [0001] The invention relates to construction engineering technology, in particular to a non-load-bearing fireproof partition wall for a scissor staircase, a scissor staircase and a construction method thereof. Background technique [0002] The scissor staircase is a double staircase structure. There are two entrances and exits on each floor to realize the fire stairs that can go up and down. The advantage is that the output is doubled to ensure the output of accidental escape. Scissor staircases are commonly used in civil buildings, and the two staircases are separated by a partition wall whose main function is fire prevention. Since the stair partition wall only needs to have fire protection function, in the traditional consciousness of the construction industry, this type of wall is mostly treated as masonry wall or panel wall from design to construction, as long as it meets the fire protection level or fire resistance time requirements of fire performance ...
