The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 to 12, the pre-buried ladder stand comprises an L-shaped ladder stand main part 1, a connecting sleeve 2 and a three-section water stopping bolt pre-buried in the structure, wherein screw threads are arranged at two ends of the L-shaped ladder stand main part 1, one end of the L-shaped ladder stand main part is connected with a pre-buried three-section water stopping bolt exposed sleeve 3, and the other end of the L-shaped ladder stand main part is connected with the connecting sleeve 2.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
firstly, the main part of the ladder is installed in the later period, so that deviation is not generated, and the appearance quality is good;
and secondly, the disassembly is convenient, and the later flexible application is convenient.
The construction method comprises the following steps:
setting a line and positioning according to the position and size of a crawling ladder required on a drawing in advance, fixing a template by using a three-section type water stopping bolt, selecting the diameter of the three-section type water stopping bolt according to the diameter requirement of the crawling ladder to meet the stress requirement of a design drawing, removing the template after the concrete is poured and the template removal time is reached, and leaving a three-section type water stopping bolt exposed sleeve 3 on the wall surface after the template is removed;
manufacturing an L-shaped ladder stand main part 1 and a connecting sleeve 2, wherein screw threads are arranged at two end parts of the L-shaped ladder stand main part 1, one end of the L-shaped ladder stand main part 1 is sleeved into a waterproof rubber mat 5 and then is screwed into a threaded hole of a three-section type water stop bolt exposed sleeve 3, and the L-shaped ladder stand main part 1 and two holes are rotated until the same horizontal line is formed between the L-shaped ladder stand main part 1 and the two holes;
screwing the connecting sleeve 2 into the other end of the L-shaped ladder stand main part 1, stopping after screwing the connecting sleeve 2 into the L-shaped ladder stand main part, sleeving the other L-shaped ladder stand main part 1 into the waterproof rubber mat 5, screwing the L-shaped ladder stand main part into the threaded hole of the three-section type water stop bolt exposed sleeve 3 at the opposite side until the two L-shaped ladder stand main parts 1 are right aligned, screwing out the connecting sleeve 2 in the L-shaped ladder stand main part 1 at one side, connecting the L-shaped ladder stand main part 1 at the other side, and fixing the two L-shaped ladder stand main parts 1 into a whole through the connecting sleeve 2 to form a U-shaped ladder stand;
after the fixing, the reinforcing screw 4 is screwed in from the reinforcing screw hole through a wrench for reinforcement, so that the connection sleeve 2 is prevented from loosening
