Embodiment
[0027] see figure 1 , figure 2 , image 3 , this embodiment provides a construction method for a building-through structure of a strong electric well, wherein the building-through structure includes a bridge frame 11 , a line pipe 12 and a bus duct 13 .
[0028] This construction method comprises the following steps:
[0029] The floor 14 in the vertical shaft reserves the hole K1 that allows each floor-through structure to pass through; wherein the holes K1 of each floor-through structure are independent of each other and adapt to the outer contour of each floor-through structure; the blocking area can be reduced by this arrangement;
[0030] On the upper surface of the floor slab 14, water retaining sills 16 surrounding the outer circumferences of the holes K1 are arranged respectively. Wall 20-30mm;
[0031] Pass each floor-through structure through the floor 14 from its corresponding hole K1; each hole K1 is larger than the corresponding floor-through structure, so th...

The invention relates to the field of building construction, and aims to solve the problem that relatively simple gap treatment on the position of a bridge penetrating floor is performed, so that theproblem of relatively poor safety performance at the position is caused; the invention provides a construction method of a strong-current well wall-penetrating structure; the construction method comprises the following steps that holes for allowing respective wall-penetrating structures to penetrate through are reserved in a floor slab in the vertical shaft, wherein the holes of all the wall-penetrating structures are independent from each other, and are adapted to the outer contour of each wall-penetrating structure; a water retaining ridge surrounding the periphery of each hole is arranged on the upper surface of the floor slab separately; the wall-penetrating structures penetrate through the floor slab from the corresponding holes of the wall-penetrating structures; each hole is largerthan the corresponding floor wall-penetrating structure, so that an annular gap with a T-shaped longitudinal section is formed among the wall-penetrating structure, the peripheral wall of the hole andthe inner peripheral surface of the water retaining ridge; and a fireproof plugging material is filled into the annular gap and is compacted to form a T-shaped annular fireproof sealing body. The construction method has the beneficial effects that water sealing can be realized while the fireproof effect of the plugging part is ensured, water leakage at the through holes is avoided, and the safetyis high.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a building-penetrating structure of a strong electric well. Background technique [0002] In the electrical shaft, such as in the strong electric well, it is necessary to pass through the wall structure such as the bridge frame through the floor to enter the upper / lower strong electric well. In the prior art, it is relatively simple to deal with the gap at the position where the bridge frame passes through the floor, which makes the safety performance at this position poor. Contents of the invention [0003] The present invention aims to provide a construction method for a strong electric well penetrating a building structure, so as to solve the problem in the prior art that the gap treatment at the position where the bridge frame penetrates the floor is relatively simple, resulting in poor safety performance at this position.
