Description

Technical Field

[0001] The invention belongs to the technical field of water receiving trough construction, and in particular relates to a water receiving trough on a top plate of an expansion joint and a construction method thereof. Background Art

[0002] With the acceleration of urbanization and the rapid growth of urban population, a large number of basements have been built in urban construction to make full use of underground space. The expansion joints of basement structures are set to prevent cracks and damage caused by factors such as concrete drying shrinkage and thermal expansion and contraction. There are greening parts on the roof of the underground garage, and there are also parts that serve as community roads. They are greatly affected by the outside world, facing the repeated effects of wind and sun, ice and snow freezing and thawing, vehicle dynamic loads, lateral pressure generated by surrounding buildings, and uneven structural settlement. The waterproof structure of the expansion joint is very important.

[0003] In the deformation process of the existing expansion joint, the water receiving trough can only rely on the deformation capacity of its own material after shaping as the structure deforms, and the deformation is relatively concentrated, that is, the force is relatively concentrated. Such continuous deformation causes great damage to the water receiving trough, and it is easy to produce cracks in the concentrated force position, causing water seepage; at the same time, the poor waterproofness of the water receiving trough after construction is also an important reason for the expansion joint leakage. Therefore, it is necessary to design a water receiving trough that is damaged by concentrated force, and also to design a construction method for a water receiving trough with high overall sealing after construction. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problem and to provide a water receiving trough for a top plate of an expansion joint and a construction method thereof.

[0005] The present invention relates to a water receiving trough for a top plate of an expansion joint, comprising a U-shaped metal trough, wherein the extension parts on both sides of the U-shaped metal trough are fixedly connected to one side of a W-shaped rubber belt, and each side of the W-shaped rubber belt away from the U-shaped metal trough is fixedly connected to a metal extension plate, and two groove groups are provided above each of the metal extension plates, and a plurality of bolt holes are provided between the two groove groups.

[0006] The present invention also relates to a construction method of an expansion joint top plate water receiving trough, and the construction of the expansion joint top plate water receiving trough comprises the following steps: S1, embedded fixed flat iron; S2. Install drip line; S3. Seal the water tank on the top plate of the expansion joint; S4, adjusting the position of the water tank on the top plate of the expansion joint; S5, fixing and installing the water tank on the top plate of the expansion joint; S6. Fill the interior of the expansion joint; S7. Construction is carried out above the expansion joint; S8. Waterproof the area above the expansion joint.

[0007] Preferably, in step S1, when constructing the beams on both sides of the expansion joint, a fixing flat iron for fastening the water trough on the top plate of the expansion joint is pre-buried at the bottom of the beams on both sides of the expansion joint, and the fixing flat iron is provided with a plurality of bolt holes.

[0008] Preferably, in step S2, drip lines are installed on both sides below the expansion joint, the length of the drip lines is equal to the length of the expansion joint, and the water seeping from the expansion joint is led by the drip lines to the water receiving groove on the top plate of the expansion joint.

[0009] Preferably, in step S3, the groove groups of the metal extension plate are filled with water-swellable waterproofing glue, and then sealing strips are provided on both the upper and lower surfaces of the metal extension plate.

[0010] Preferably, in step S4, the drainage direction of the water receiving trough on the top plate of the expansion joint is adjusted until all the water flow in the U-shaped metal trough flows into the drainage pipe.

[0011] Preferably, in step S5, the water trough of the expansion joint top plate and the sealing strip are fixed to the beams on both sides of the expansion joint by means of fixing flat irons using expansion bolts.

[0012] Preferably, in step S6, the polystyrene strips are cut to a size suitable for the expansion joint, and the interior of the expansion joint is filled with the polystyrene strips.

[0013] Preferably, in step S7, a V-shaped waterstop steel plate is fixedly installed above the expansion joint, or a rubber waterstop is buried above the expansion joint, and then concrete is poured and the joint is grouted with asphalt.

[0014] Preferably, in step S8, a waterproof coating is applied to the concrete layer above the expansion joint, and then a waterproof membrane is laid, and a waterproof protective layer is poured and then covered with soil and greened.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: (1) The stress on the water trough on the top plate of the expansion joint is concentrated on the U-shaped metal trough and the W-shaped rubber belt. In the early stage of the expansion joint deformation, the stress is mainly on the W-shaped rubber belt, and the W-shaped rubber belt is elastic, so it will not cause damage to the water trough on the top plate of the expansion joint when subjected to stress. In the late stage of the expansion joint deformation, the W-shaped rubber belt and the U-shaped metal trough are subjected to stress at the same time. The W-shaped rubber belt shares most of the stress due to elastic deformation, so the plastic deformation of the U-shaped metal trough after being subjected to stress is not serious, thereby reducing the damage to the water trough on the top plate of the expansion joint caused by the expansion joint deformation. (2) The connection between the water receiving groove of the expansion joint top plate and the expansion joint beam body is a metal extension plate, which is provided with a groove group, and the groove group is filled with water-expanding waterproof glue, and sealing strips are provided on the upper and lower surfaces of the metal extension plate during construction, so as to effectively improve the waterproof ability of the connection between the water receiving groove and the expansion joint beam body; (3) The construction method of the expansion joint top plate water trough is to fill the expansion joint with polystyrene strips, and perform water stopping and waterproofing treatment above the expansion joint, so that the overall sealing of the expansion joint top plate water trough after construction is high.
