Description

Technical Field

[0001] The invention relates to a steel plate water stop device, in particular to a steel plate water stop device which is installed after a pre-buried groove is separated from a wall ditch. Background Art

[0002] In many construction projects, whether it is underground structures such as basements, underground parking lots, or some hydraulic structures with waterproofing requirements, preventing water leakage has always been a key issue. Water leakage will not only affect the normal use of the interior of the building, causing dampness, mold, and damage to the decorative layer of the wall, but may also have an adverse effect on the durability of the building structure. The wall ditch is a structure used for drainage and water diversion in the building. It is located in a special position and is prone to leakage. At present, there are often the following problems in the construction of the wall ditch:

[0003] 1. The wall groove intersects vertically with the main structure plate surface, and conventional water stop strips cannot be set.

[0004] 2. Although the industry is currently promoting the one-time pouring construction technology of the wall ditch and the main structure slab as a whole, due to the limitations of on-site construction conditions, some wall ditches still cannot avoid secondary pouring construction. Since there is a construction joint between the wall ditch and the main structure, the risk of leakage is relatively high.

[0005] 3. As a key component of the underground space waterproofing system, the wall trench is the final line of defense to prevent water leakage. Once the wall trench itself has leakage problems, usually, the relevant installation and decoration projects have already started, and effective plugging operations will face great challenges. It is necessary to find the leakage points and repair them in the completed decoration and installation projects. In addition, leakage problems may also lead to equipment damage, material waste, and construction delays.

[0006] Ensuring the waterproof performance of the wall ditch is the key to avoiding a series of subsequent complex problems. Therefore, it is necessary to develop a water-stopping device that can effectively improve the waterproof effect of the secondary cast wall ditch and has the characteristics of convenient construction. Summary of the invention

[0007] The present invention aims to provide a device for pre-buried grooves in an away wall ditch and then installed with a steel plate waterstop. When the away wall ditch of an underground structure is constructed by secondary casting, the grooves can be pre-buried and the steel plate waterstop can be installed later to form a away wall ditch waterstop system, increase the water seepage path between the away wall ditch and the structural layer, improve the waterproof effect of the secondary casting away wall ditch, and meet the demand for secondary casting of away wall ditch in underground space. Leakage prevention and control needs.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0009] A device for installing a steel plate waterstop after a pre-embedded groove in an away wall ditch comprises a customized pre-embedded groove, an L-shaped steel plate waterstop and a steel wedge. During the construction of the main structure, the customized pre-embedded groove is fixedly connected to the positioning steel bar, the customized pre-embedded groove 1 is installed with the L-shaped steel plate waterstop, and a steel wedge is knocked into the gap between the customized pre-embedded groove and the L-shaped steel plate waterstop to fix the L-shaped steel plate waterstop. At the same time, before pouring the concrete of the away wall ditch, a layer of water-swelling glue is added to the water-facing side of the L-shaped steel plate waterstop to increase the waterproof effect of the away wall ditch waterstop device.

[0010] Furthermore, the customized embedded slots are fixed to the positioning steel bars by welding.

[0011] Furthermore, the customized embedded slots are filled with butter to prevent concrete from flowing in.

[0012] A construction method for installing a steel plate waterstop device after pre-embedded grooves in an off-wall ditch. During the construction of the main structure plate structure, a positioning steel bar is added and spot-welded to the main bar for positioning and installation of a customized pre-embedded groove. The customized pre-embedded groove and the positioning steel bar are fixedly connected by welding. Before pouring the concrete of the main structure, butter is used to fill the groove of the customized groove to prevent concrete from flowing in. During the construction of the off-wall ditch, concrete on the surface of the pre-embedded groove is chiseled out and concrete debris is cleaned. During the process, it is not necessary to completely clean the butter in the customized pre-embedded groove, and an L-shaped steel plate waterstop is inserted. At the same time, a steel wedge is knocked into the bottom of the L-shaped steel plate waterstop to strengthen fixation. After the off-wall ditch steel bars are tied and the mold is sealed, a water-expanding waterstop glue is set on the water-facing surface of the L-shaped steel plate waterstop from the top opening of the template before pouring the off-wall ditch concrete to prevent the waterstop glue from failing in water in advance. After the construction of the waterstop glue is completed, the off-wall wall concrete is poured.

[0013] The beneficial effects of the present invention are:

[0014] The steel plate water stop device installed after the pre-buried groove of the wall ditch of the present invention adds two waterproof measures for the wall ditch of secondary pouring, which can effectively reduce the risk of water leakage in the wall ditch of secondary pouring. The device has a simple structure, is easy to customize and process, and is convenient for on-site installation and construction, which is conducive to controlling the construction period and labor input.

[0021] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0022] like Figures 1 to 6 As shown, a steel plate waterstop device is installed after the pre-embedded groove of the off-wall ditch of the present invention, which adds a waterstop device to the off-wall ditch construction joint of the secondary pouring, and effectively reduces the risk of leakage in the off-wall ditch secondary pouring construction joint. The device includes a customized pre-embedded groove 1, an L-shaped steel plate waterstop 2, and a steel wedge 3. During the construction of the main structure, the customized pre-embedded groove 1 is fixed to the positioning steel bar by welding, and the customized pre-embedded groove 1 is filled with butter to avoid pollution. In the later stage of off-wall ditch construction, there is no need to completely clean the butter inside the customized pre-embedded groove, install the L-shaped steel plate waterstop 2, knock the steel wedge 3 into the gap between the customized pre-embedded groove 1 and the L-shaped steel plate waterstop 2 to fix the L-shaped steel plate waterstop 2, and at the same time, before the concrete of the off-wall ditch is poured, a water-expanding glue 4 is added on the water-facing side of the L-shaped steel plate waterstop 2 to increase the waterproof effect of the off-wall ditch waterstop device.

[0023] The specific construction steps of the steel plate waterstop device installed after the pre-embedded groove of the away wall ditch of the present invention are: ① Customize the pre-embedded groove, embed it during the construction of the main structure plate, and fill the groove of the pre-embedded groove with butter; ② When the away wall ditch is constructed in the later stage, the concrete on the surface of the main structure is chiseled off, and the chiseled debris is cleaned up. It is not necessary to completely clean out the butter inside the groove, install the L-shaped steel plate waterstop, and knock a steel wedge into the bottom of the L-shaped steel plate waterstop to strengthen the fixation; ③ Before pouring the away wall ditch concrete, set a water-swelling waterstop glue on the water-facing surface of the L-shaped steel plate waterstop, and then pour the away wall ditch concrete.

[0024] This case takes the construction of the wall trench of the subway station as an example:

[0025] During the construction of the main structural plate structure, an additional positioning steel bar is spot-welded to the main reinforcement for positioning and installation of the customized embedded slot of this device. The customized embedded slot and the positioning steel bar are fixedly connected by welding. Before pouring the concrete of the main structure, the customized slot is filled with butter to prevent concrete from flowing in. During the construction of the away wall ditch, the concrete on the surface of the embedded slot is chiseled off and the concrete debris is cleaned. During the process, there is no need to completely clean the butter in the slot, insert the L-shaped steel plate waterstop, and knock a steel wedge into the bottom of the L-shaped steel plate waterstop to strengthen the fixation. After the steel bars of the away wall ditch are tied and the mold is sealed, a water-expanding waterstop is set on the water-facing surface of the L-shaped steel plate waterstop through the top opening of the template before pouring the away wall ditch concrete to prevent the waterstop from failing prematurely when exposed to water. After the construction of the waterstop is completed, the away wall concrete is poured.
