Detailed Description
As shown in the figure, the indoor ladder for old community reconstruction construction comprises a post frame 1, a side beam 2, a stair step 3 and a handrail 4; the column frame 1 is in an inverted U shape and is arranged in front of an original building crossing for old community reconstruction construction; two side beams 2 are arranged in parallel, one end of each side beam 2 is fixed with the upper part of the column frame 1, and the other end of each side beam extends to the ground; the stair steps 3 are detachably arranged on the side beams 2; handrail 4 sets up on the curb girder 2 of the both sides of stair step 3, and curb girder 2 adopts ㄈ shaped steel, and every curb girder 2 includes 4 fixed curb girder sections 8 that link up, the curb girder section passes through girder steel connection piece 5 connection fixed, and girder steel connection piece 5 is in the curb girder outside. The steel beam connecting pieces 5 are provided with bolt holes, the side beam sections are provided with corresponding bolt holes, and the side beam sections are fixed in a bolt fixing mode through the steel beam connecting pieces 5.
Stair step 3 adopts the steel sheet welding to form, and stair step 3 is fixed through L type connecting plate 6 with curb girder 2, and L type connecting plate welding is inboard at curb girder 2, is located stair step 3 top, and stair step 3 passes through L type connecting plate and 2 bolt fixings of curb girder.
The side beam 2 is welded with handrail slots 7, and the bottom ends of the handrails 4 are inserted into the handrail slots 7 for assembly and fixation.
The working principle is as follows: when the elevator is installed, the fixed column frame 1 is installed firstly, the support is built to install the side beam 2 in a segmented mode, the side beam 2 penetrates through an additional elevator shaft in construction, and then the stair step 3 and the handrail 4 are installed on the side beam 2. Residents can enter the half-floor platform of the original corridor through the step ladder, so that the residents can enter the house.
The sectional installation of the side beam 2 and the detachable installation of the handrail and the side beam are convenient for construction and transportation.
