Description

Technical Field

[0001] The utility model relates to the technical field of post-cast strip waterproofing, and in particular to an assembled advanced water-stopping prefabricated plate for a post-cast strip of a basement exterior wall. Background Art

[0002] When pouring the basement, the basement floor and exterior wall need to be poured separately, and a construction joint will be formed at the joint of the new and old concrete. When this construction joint is located below the groundwater level, water seepage is likely to occur. At this time, a waterstop plate is needed. When pouring the lower layer of concrete, half of the waterstop plate is pre-buried and the other half is exposed. The remaining part will be buried during the next pouring, thereby solving the problem of water seepage.

[0003] At present, waterstop plates are often made of 3mm thick steel plates. Adjacent waterstop plates are fixedly connected by overlap welding to achieve the effect of connection and waterproofing. However, the installation and arrangement of waterstop plates around the basement requires welding of many joints. The staff needs to move the welding equipment many times, and each welding installation time is long, which is very inconvenient to operate. Therefore, an assembled advanced waterstop prefabricated plate for the post-cast strip of the basement exterior wall is needed to solve the above problems. Utility Model Content

[0007] Preferably, the positioning mechanism includes a mounting seat fixedly connected to the water stop plate body, an adjusting bolt threadedly connected to the mounting seat, and a pressure plate, the pressure plate is slidably connected to the water stop plate body, and the end of the adjusting bolt is rotatably connected to the pressure plate.

[0008] Preferably, a sealing gasket is provided on the outer side wall of the water stop plate body located on one side of the connecting protrusion.

[0009] Preferably, four connecting through grooves and four connecting protrusions are provided, and they are distributed at the corners of a rectangle.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-4 , the utility model provides the following technical solutions:

[0019] A prefabricated assembled advanced water-stopping plate for the post-cast strip of the exterior wall of a basement comprises a water-stopping plate body 1, a connecting groove 2 is provided on the side surface of one end of the water-stopping plate body 1, a connecting protrusion 3 which can cooperate with the connecting groove 2 is connected to the side surface of the other end of the water-stopping plate body 1, and the connecting protrusion 3 is provided with an inclined surface for fitting and pressing two adjacent water-stopping plate bodies 1. Bending parts are provided at the upper and lower edges of the water-stopping plate body 1. The setting of the bending parts can make the opening of the steel plate face the outside of the basement, which is more conducive to blocking water seepage and improving the water-stopping effect.

[0020] The waterstop plate body 1 is also provided with a positioning mechanism for laterally pushing adjacent waterstop plate bodies 1; the positioning mechanism comprises a mounting seat 4 fixedly connected to the waterstop plate body 1, an adjusting bolt 5 threadedly connected to the mounting seat 4, and a pressure plate 6; the pressure plate 6 is slidably connected to the waterstop plate body 1, and the end of the adjusting bolt 5 is rotatably connected to the pressure plate 6; by rotating the adjusting bolt 5, the pressure plate 6 can be driven to move, thereby squeezing the ends of adjacent waterstop plate bodies 1, and combined with the setting of the inclined surface on the connecting protrusion 3, a quick sealing connection of the two waterstop plate bodies 1 can be achieved.

[0021] The water stop plate body 1 is provided with a sealing gasket 7 on the outer wall on one side of the connecting protrusion 3. The setting of the sealing gasket 7 can improve the sealing performance of the connection between two adjacent water stop plate bodies 1; the connecting grooves 2 and the connecting protrusions 3 are each provided with four, and are distributed in the corner positions of a rectangle. The setting of the four connecting grooves 2 and the connecting protrusions 3 can make the connection between adjacent water stop plate bodies 1 more stable.

[0022] The working process of the utility model is as follows:

[0023] When it is necessary to connect two adjacent waterstop plate bodies 1, first, snap the connecting protrusion 3 on one waterstop plate body 1 into the connecting groove 2 on the other waterstop plate body 1, rotate the adjusting bolt 5 to make the adjusting bolt 5 move on the mounting seat 4, and the adjusting bolt 5 drives the pressure plate 6 to approach the end of the connected waterstop plate body 1 and gradually tighten it. During this process, the inclined surface on the connecting protrusion 3 slides in the connecting groove 2, so that the side walls of the two connected waterstop plate bodies 1 are gradually pressed and sealed. At the same time, the pressure plate 6 also limits the lateral position of the two waterstop plate bodies 1, thereby realizing a quick and sealed connection of the two waterstop plate bodies 1.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
