Technical Field
[0001] This utility model relates to the field of building technology, specifically to a water-stopping device for horizontal construction joints in underground exterior walls. Background Technology
[0002] In box-type foundations or basements, the concrete for the bottom slab, exterior wall panels, and top slab is poured separately. When the wall panel concrete is poured next time, a construction cold joint will appear. When this joint is located below the groundwater level, water seepage is likely to occur. Therefore, this joint needs to be technically treated to prevent water seepage. The most common treatment method is to install a water-stop steel plate.
[0003] However, currently, waterstop steel plates on the market are all installed using a welding connection method. One end of the steel bar is welded to the waterstop steel plate, and the other end is welded to the steel bar to be poured. However, after welding the waterstop steel plate, due to welding errors, it is often necessary to extend the connecting steel bar to get close to the steel bar to be poured. Welding is time-consuming and laborious, reducing installation efficiency. Utility Model Content
[0004] This utility model provides a water-stopping device for horizontal construction joints in underground exterior walls, which can effectively solve the problem mentioned in the background art that the water-stopping steel plates are all connected by welding during installation. One end of the steel bar is welded to the water-stopping steel plate, and the other end is welded to the steel bar to be poured. However, after welding the water-stopping steel plate, due to welding errors, it is often necessary to extend the connecting steel bar to get close to the steel bar to be poured. Welding is time-consuming and labor-intensive, reducing installation efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-stopping device for horizontal construction joints of underground exterior walls, comprising a water-stopping steel plate, wherein connecting and fixing components are symmetrically installed on both sides of the water-stopping steel plate, and the connecting and fixing components include connecting nuts, connecting rods, U-shaped iron wires, anti-loosening washers, screws, extruded iron sheets, anti-slip sheets, and fixing nuts;
[0006] The water-stop steel plate is symmetrically welded with connecting nuts on both sides. A connecting rod is threadedly connected inside the connecting nut. A U-shaped iron wire is welded to one end of the connecting rod. An anti-detachment washer is placed on one side of the middle of the U-shaped iron wire. A screw is movably installed through the middle of the anti-detachment washer. An extruded iron sheet is slidably sleeved in the middle of the screw. An anti-slip plate is glued to the end of the extruded iron sheet near the screw. A fixing nut is threadedly connected to the end of the screw.
[0007] According to the above technical solution, the ends of the connecting rods are symmetrically welded to both ends of the U-shaped wire, and the outer side of the U-shaped wire is a rough curved surface.
[0008] According to the above technical solution, the anti-detachment pad is a circular piece with a hole in the middle, and the outer diameter of the anti-detachment pad is larger than the width of the U-shaped wire.
[0009] According to the above technical solution, the extruded iron sheet is a rectangular sheet with rounded corners at both ends, and a round hole is opened at the screw corresponding to the extruded iron sheet.
[0010] According to the above technical solution, a sleeve is welded to one end of the water-stop steel plate, a water-swellable rubber plate is bonded to one end of the water-stop steel plate, aluminum strips are bonded to both sides of the water-swellable rubber plate, and aluminum foil is bonded to both sides of the water-swellable rubber plate.
[0011] According to the above technical solution, the aluminum strip is chamfered near the end of the sleeve, and the side of the aluminum foil away from the water-swellable rubber plate is a smooth plane.
[0012] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use;
[0013] 1. A connecting and fixing assembly is provided. Four connecting nuts are symmetrically welded to both sides of the waterstop steel plate. A U-shaped iron wire is welded to the unthreaded end of the connecting rod. After the screw is fitted with an anti-loosening washer, it passes through the middle of the U-shaped iron wire. The above parts are transported separately to the installation position and then reassembled at the installation position. Compared with on-site welding, it is more labor-saving and convenient.
[0014] During on-site assembly, align one threaded end of the connecting rod with the connecting nut and screw it in. Slide the screw along the U-shaped wire until the pressing iron plate is close to the rebar to be connected. Rotate the pressing iron plate so that one side of the anti-slip plate is in contact with the rebar. Rotate the fixing nut so that the pressing iron plate presses and fixes the rebar, thus completing the positioning process.
[0015] If the welding error is large enough to prevent the extruded iron sheet from fitting the rebar, bend the U-shaped iron wire until the extruded iron sheet is close to the rebar to be connected. This allows for connection even with large errors. Bending the U-shaped iron wire is simpler and less strenuous, while also ensuring the connection effect, making the connection operation more convenient.
[0016] 2. If multiple water-stop steel plates need to be installed at the installation location, the ends of adjacent water-stop steel plates are joined together, and the water-swellable rubber sheet and aluminum strip are embedded into the corresponding sleeve. The water-swellable rubber sheet and aluminum strip can be bent as needed, and there is no need to weld the adjacent water-stop steel plates. The length of the water-swellable rubber sheet embedded into the corresponding sleeve is determined according to the site dimensions to avoid cutting the water-stop steel plates. The water-swellable rubber sheet expands inside the sleeve when it comes into contact with water, reducing the chance of water seepage and ensuring the waterproof effect while further improving the convenience of installation.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figure 1-3 As shown, this utility model provides a technical solution for a water-stopping device for horizontal construction joints in underground exterior walls, including a water-stopping steel plate 1. Connecting and fixing components 2 are symmetrically installed on both sides of the water-stopping steel plate 1. The connecting and fixing components 2 include a connecting nut 201, a connecting rod 202, a U-shaped iron wire 203, an anti-detachment washer 204, a screw 205, an extruded iron sheet 206, an anti-slip sheet 207, and a fixing nut 208.
[0027] The water-stop steel plate 1 has symmetrically welded connecting nuts 201 on both sides. Connecting rods 202 are threaded into the connecting nuts 201. A U-shaped wire 203 is welded to one end of the connecting rod 202. The edges of the connecting rod 202's end face are symmetrically welded to both ends of the U-shaped wire 203. The outer surface of the U-shaped wire 203 is rough and curved to improve the fixing effect. An anti-detachment washer 204 is placed on one side of the middle of the U-shaped wire 203. The anti-detachment washer 204 is a circular piece with a hole in the middle, and its outer diameter is larger than the width of the U-shaped wire 203 to prevent... The anti-detachment washer 204 passes through the middle of the U-shaped iron wire 203, affecting the fixing effect. The anti-detachment washer 204 is movably installed through the middle of the screw rod 205. The screw rod 205 is slidably sleeved with a pressing iron sheet 206. The pressing iron sheet 206 is a rectangular piece with rounded corners at both ends. The pressing iron sheet 206 has a round hole corresponding to the screw rod 205 to facilitate the pressing iron sheet 206 sliding along the screw rod 205. An anti-slip piece 207 is glued to the end of the pressing iron sheet 206 near the screw rod 205. The end of the screw rod 205 is connected to a fixing nut 208 by a thread.
[0028] A sleeve 4 is welded to one end of the water-stop steel plate 1, and a water-swellable rubber plate 5 is bonded to one end of the water-stop steel plate 1. Aluminum strips 6 are bonded to both sides of the water-swellable rubber plate 5, and aluminum foil 7 is bonded to both sides of the water-swellable rubber plate 5. The aluminum strips 6 are chamfered at the end near the sleeve 4, and the side of the aluminum foil 7 away from the water-swellable rubber plate 5 is a smooth plane, which facilitates the connection between the water-swellable rubber plate 5 and the sleeve 4.
[0029] The working principle and usage process of this utility model are as follows: Four connecting nuts 201 are symmetrically welded to both sides of the water-stop steel plate 1. A U-shaped iron wire 203 is welded to the unthreaded end of the connecting rod 202. After the screw rod 205 is fitted with the anti-loosening washer 204, it passes through the middle of the U-shaped iron wire 203. The screw rod 205 is then fitted with the extrusion iron sheet 206 and the fixing nut 208 in sequence. The above parts are transported separately to the installation position and then reassembled at the installation position. Compared with on-site welding, this method is more labor-saving and convenient.
[0030] During on-site assembly, align one threaded end of the connecting rod 202 with the connecting nut 201 and screw it in. Slide the screw 205 along the U-shaped wire 203 until the pressing plate 206 is close to the rebar to be connected. Rotate the pressing plate 206 so that one side of the anti-slip plate 207 is in contact with the rebar. Rotate the fixing nut 208 so that the pressing plate 206 presses and fixes the rebar, completing the positioning process. If the welding error is large and the pressing plate 206 cannot be in contact with the rebar, bend the U-shaped wire 203 until the pressing plate 206 is close to the rebar to be connected. This allows for connection even with large errors. Compared with bending the rebar in traditional connection, bending the U-shaped wire 203 is simpler and less labor-intensive, while also ensuring the connection effect. The connection operation is more convenient.
[0031] After a single waterstop steel plate 1 is installed, if multiple waterstop steel plates 1 need to be installed at the same location, the ends of adjacent waterstop steel plates 1 are joined together. The joining process involves embedding the water-swellable rubber plate 5 and the aluminum strip 6 into the corresponding sleeve 4. During this process, the water-swellable rubber plate 5 and the aluminum strip 6 can be bent as needed, which is more labor-saving than bending the waterstop steel plate 1 and eliminates the need to weld adjacent waterstop steel plates 1. The length of the water-swellable rubber plate 5 embedded into the corresponding sleeve 4 is determined according to the site dimensions to avoid cutting the waterstop steel plate 1. The water-swellable rubber plate 5 expands inside the sleeve 4 when it comes into contact with water, reducing the chance of water seepage and ensuring the waterproof effect while further improving the convenience of installation.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
