Detailed Description

The present invention will be further described with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art.

As shown in the attached figure 2, the novel stair baffle (02) is an L-shaped section bar, and the structure and the principle of the section bar are explained as follows: the section and the size of the stair baffle profile are designed into an L-shaped section, the size of a short edge is designed to be L2-55 mm, the thickness of the short edge is designed to be D1-6 mm in order to ensure good stress when the pin is connected; according to the standard of stairs in buildings, more than 90% of the stair step height in high-rise buildings is less than or equal to 175mm, the long edge of the stair cover plate is used for plugging cement, and in order to meet the universality, the size of the long edge is designed to be L1-175 mm; the material saving is guaranteed on the premise of meeting the strength, and the thickness of the long side is designed to be D2-4 mm.

As shown in fig. 3, dissect novel stair baffle (02) L type cross-section bar shown in fig. 2, if the stair step height is 175mm, then need not to dissect, only need to correspond length L1 become 175 mm's stair baffle section bar and interior shrouding section bar and weld can, if the stair baffle height is less than 175mm, only need to cut off a small part with stair baffle section bar long edge direction, cut off L type cross-section panel promptly and dissect position (22), leave L type cross-section panel (22) that length is L1'.

As shown in fig. 4, the novel stair baffle (02) is an inner sealing plate (3), the inner sealing plate (3) is a profile with two convex ends, the section length L3 of the inner sealing plate (3) is 61mm, the thicknesses D3 of the two ends of the inner sealing plate (3) are 8mm, and the middle thickness D4 is 6 mm.

As shown in fig. 5, the novel stair baffle (02) is a welded structure, and is formed by welding an L-shaped section plate (22) and an inner sealing plate (3), wherein L1' is matched with the height of the stair, L2 is 55mm, L3 is 61, and L4 is 65.

As shown in fig. 6, novel stair baffle (02) and stair apron (04) cooperation installation connect stair apron (04) of two-stage stair, and stair baffle minor face cooperates with stair apron (04) in the horizontal direction, need to push down stair apron (04) through stair baffle tip shrouding and forms cooperation position (05), and vertical direction stair apron (04) and stair apron (02) use pin joint (06), and L0 is 260.

The method simplifies the processing procedure of the stair baffle, and can be seen that the traditional processing method cuts at least 2 times in each processing regardless of the height of the stair baffle, and the processing method cuts at most once; the method can reduce the loss rate of the base material to a great extent, the loss rate of the base material exceeds 10% in the traditional processing method, and the maximum loss rate of the base material in the processing method is 4% due to the fact that 90% of the step height of the stairs in the building is larger than or equal to 161.1mm and the maximum loss rate of the base material is calculated according to the step height of 161.1 mm.

The present patent provides a new stair tread and the profile structure used, and provides the corresponding processing method, not only limited to the description and the embodiments, but also includes the equivalent changes or modifications of the structure, characteristics and principle described in the patent scope.
