Problems solved by technology

[0004] However, in the actual use process, the wall deforms on the side close to the expansion joint with time, and the installation groove of the waterstop in the wall will also deform to a certain extent, but the existing waterstop After the installation groove is deformed, the fit between the installation groove and the installation groove will become poor, so that there will be a gap between the water stop belt and the installation groove, so that water will easily flow into the expansion joint through the gap between the water stop belt and the installation groove

Embodiment 1

[0038] Embodiment 1: A stainless steel U-shaped body used for expansion joints, see the attached figure 1 And attached figure 2 , comprising a bottom plate 2, a connecting plate 4 arranged above the bottom plate 2, an air bag 3 arranged between the bottom plate 2 and the connecting plate 4, an air pump 5 fixedly connected to one side of the wall 1, and used for connecting the air pump 5 to the air bag 3 The connecting pipe 51 together and the pressure gauge 52 fixedly connected on the connecting pipe 51 for measuring the air pressure in the connecting pipe 51 and the air bag 3; the bottom plate 2 is made of stainless steel, and the connecting plate 4 is made of rubber; the air bag 3 The top and the bottom are in contact with the bottom of the bottom plate 2 and the top of the connecting plate 4 respectively; The mounting plate 22 in the groove 12; the connecting plate 4 includes a U-shaped part 41 with the opening facing upwards in the expansion joint 11 and a mounting part ...

Embodiment 2

[0042] Embodiment 2: A stainless steel U-shaped body for expansion joints, see attached figure 1 And attached figure 2 The difference between this embodiment and the first embodiment is that the mounting plate 22 and the mounting portion 42 are arranged obliquely, the side of the mounting plate 22 away from the U-shaped plate 21 is fixedly connected with the horizontal plate 24, and the mounting portion 42 is away from the U-shaped portion 41. One side is fixedly connected with a horizontal portion 45 , the limiting block is fixedly connected to the top of the horizontal plate 24 , and the limiting plate is fixedly connected to the bottom of the horizontal portion 45 . A side of the mounting plate 22 facing away from the U-shaped plate 21 is inclined upward.

[0043] The advantage of this embodiment over Embodiment 1 is that when the water flows to the top of the installation part 42, the installation part 42 is inclined, and the water flows into the U-shaped part 41 under t...

Embodiment 3

[0044] Embodiment three: a method for using a stainless steel U-shaped body for expansion joints, comprising the following steps:

[0045] a. Install the stainless steel U-shaped body: the bottom plate 2, the air bag 3 and the connecting plate 4 are installed together, so that the guide plate 44 is embedded in the guide groove 231;

[0046] b. Open installation groove 12: On the wall body 1 on both sides of the expansion joint 11, an installation groove 12 that cooperates with both sides of the stainless steel U-shaped body is opened;

[0047] c. Install the stainless steel U-shaped body: install the bottom plate 2, the air bag 3 and the connecting plate 4 installed together into the installation groove 12;

[0048] d. Install the air pump 5: install the air pump 5 on the side of the wall 1, connect the air pump 5 and the air bag 3 with the connecting pipe 51, and then install the air pressure gauge on the connecting pipe 51 near the air pump 5;

[0049] e. Inflation: Tu...

Abstract

The invention discloses a stainless-steel U-shaped body for an expansion joint and an application method thereof, and relates to a waterproof structure. The problem that through an existing water stopping belt, after an installing groove is deformed, water easily flows into an expansion joint from a gap between the water stopping belt and the installing groove is solved. According to the technicalscheme, the stainless-steel U-shaped body for the expansion joint comprises a bottom plate, an air sac, a connecting plate arranged at the top of the air sac, a connecting pipe communicated with theair sac and a pressure meter arranged on the connecting pipe and used for measuring air pressure in the connecting pipe and the air sac; the bottom plate comprises a U-shaped plate which is located inthe expansion joint and has an opening formed upwards and an installing plate which is fixedly connected to the two sides of the top of the U-shaped plate and extends into the installing groove of awall; the connecting plate comprises a U-shaped part located at the top of the U-shaped plate and an installing part which is fixedly connected on the two sides of the top of the U-shaped part, extends into the installing groove of the wall, and is parallel to the installing plate, the connecting plate can be expanded shrunk along with shaped changes of the installing groove, and good fitting between the connecting plate and the installing groove invariably exists.

Description

technical field [0001] The invention relates to a waterproof structure, more specifically, it relates to a stainless steel U-shaped body used for expansion joints and its application method. Background technique [0002] The concrete wall will expand and deform after the construction is completed, which will inevitably lead to a certain amount of cracks in the concrete structure. In order to prevent the irregular deformation of the concrete structure due to deformation during use, it is often installed expansion joints. In order to prevent water from entering the expansion joint and affecting the wall, a water stop is often installed in the expansion joint. [0003] In the prior art, a Chinese utility model patent document with the authorized announcement number CN205035764U discloses a new type of rubber waterstop, which consists of a rubber waterstop main board, a rubber waterstop U-shaped plate, a plastic diaphragm, a strength weakening groove, The main plate is compose...
