Description

Technical Field

[0001] The utility model relates to the technical field of wall connection, in particular to a water-stopping structure device for a connection between a new and an old concrete wall. Background Art

[0002] In construction projects, when the layout of the building space is replanned and a new concrete wall needs to be built on one side of the original concrete wall, usually only waterproof coating or waterproof membrane is used to achieve the waterproof effect. Although it plays a certain role, the waterproof effect is still not ideal.

[0003] For example, the utility model with announcement number CN218622677U discloses a waterproof structure device for the connection between new and old concrete walls, including a first cast wall, a later cast wall and a waterproof board. The first cast wall and the later cast wall are cast adjacent to each other, and the waterproof board is fixedly connected to the same side walls of the first cast wall and the later cast wall at the same time. A water stop ring is preset in the first cast wall, and the other end of the water stop ring is cast in the later cast wall. The present application can reduce the possibility that water in the bathroom will seep through the construction joint to the bonding layer between the waterproof board and the exterior wall surface, thereby reducing the bonding strength between the waterproof board and the exterior wall surface.

[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing waterproof structural devices at the connection between the new and old concrete walls use various structures such as waterproof boards to seal the connection to reduce the water in the bathroom from seeping through the construction joints to the bonding layer between the waterproof board and the exterior wall surface, but most of the connections are sealed with waterproof membranes, but some waterproof membranes cannot fit tightly at the connection between the two sets of walls at the corners before heating, making it impossible for subsequent waterproof membranes to tightly seal the connection between the two sets of walls, thereby reducing the practicality of the device.

[0005] For this purpose, a water-stopping structure device is proposed for the connection between new and old concrete walls. Utility Model Content

[0009] Furthermore, the positioning mechanism includes an L-shaped slider, which is slidably connected to the inside of the groove of the waterproof rubber pad. A slot is provided on the inner side wall of the L-shaped slider, and a slider is slidably connected to the inner wall of the slot. A positioning plate is installed on the side of the slider away from the L-shaped slider, and the back of the positioning plate is attached to the front of the waterproof rubber pad. Threaded holes are provided on the side of the L-shaped slider and the positioning plate away from the waterproof rubber pad.

[0010] Furthermore, a scale mark is provided on a side of the slider away from the positioning plate, and a side of the scale mark away from the positioning plate is attached to an inner wall of the slot of the L-shaped slider.

[0011] Furthermore, a mounting groove is provided on the upper surface of the positioning plate, and the inner contour of the mounting groove is matched with the outer contour of the positioning piece at the outer end of the waterproof rubber pad.

[0012] Furthermore, the limiting mechanism includes a limiting block, a groove is provided on the side of the L-shaped slider away from the waterproof rubber pad, the limiting block is slidably connected to the inside of the groove of the L-shaped slider, the top of the inner wall of the limiting block is attached to the upper surface of the slider, the upper surface of the limiting block and the bottom of the inner wall of the groove of the L-shaped slider are both provided with through holes, and pins are inserted into the through holes of the limiting block and the L-shaped slider.
