[0002] Globally, with the continuous advancement of infrastructure construction and the increasing requirements for waterproofing performance of buildings, the application of waterstop steel plates in various fields such as construction, water conservancy, and transportation is becoming more and more widespread. In particular, the demand for waterstop steel plates continues to grow in some engineering projects with extremely high waterproofing requirements. The existing connection of waterstop steel plates adopts welding process. The existing welding connection process of waterstop steel plates has the following drawbacks: (1) There are many common welding defects such as heat deformation, false welding, missing welding, cracks, and porosity in the welding process; (2) The standard welding process requires double-sided welding, but under special working conditions (such as basement floor slabs and roof slabs), it is impossible to meet the double-sided welding operation space; (3) Welding is a hot work operation, and safety management is more difficult.

[0003] In view of this, it is necessary to design a device for connecting water-stop steel plates to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for connecting waterstop steel plates that solves the problem of insufficient operating space in traditional welding under special working conditions, avoids safety risks caused by hot work, and ensures the connection quality of waterstop steel plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A device for connecting water-stop steel plates, comprising: The box body has a cavity inside, and the two sides of the box body are respectively provided with insertion seams for the water-stop steel plate to extend into the cavity. The limiting components are symmetrically arranged in multiple ways along the center of the box. Each limiting component includes a limiting block disposed in the cavity and a fastener disposed on the side of the box away from the limiting block and movable relative to the side of the box, so that limiting areas of different sizes are formed between the fastener and the limiting block along the width direction of the waterstop steel plate. The glue injection assembly is used to fill the cavity with waterproof sealant, including a glue injection section located at the bottom of the box and a glue dispensing section located at the top of the box.

[0006] As a further improvement of this utility model, the shape of the insertion joint is adapted to the cross-sectional shape of the waterstop steel plate.

[0007] As a further improvement of this utility model, the diameter of the insertion joint is greater than or equal to the cross-sectional width of the waterstop steel plate.

[0008] As a further improvement of this utility model, the insertion joint is C-shaped, including an upper oblique section, a vertical section and a lower oblique section connected in sequence.

[0009] As a further improvement of this utility model, the installation height of the limiting block is located within the height range of the vertical section of the joint.

[0010] As a further improvement of this utility model, the limiting block is a support column set on the inner wall of the back of the box, and the fastener is a bolt set on the front of the box and threadedly connected to the front of the box, corresponding to the support column.

[0011] As a further improvement of this utility model, the horizontal projection of the end of the limiting block away from the side of the box is on the same plane as the horizontal projection of the corresponding insertion seam on the side near the support column.

[0016] 2. This utility model uses the box body and the limiting component to mechanically connect and fix the water-stop steel plate. By setting the glue injection component, waterproof sealant can be filled into the cavity to seal and stop water. At the same time, the waterproof sealant can also strengthen the connection between the two water-stop steel plates to a certain extent, avoiding the occurrence of common welding quality defects.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] Please see Figures 1-3 As shown, this utility model provides a device for connecting water-stop steel plates, comprising: Box body 10, the box body 10 has a cavity 11 inside, and the box body 10 has corresponding insertion joints 12 on both sides for the water-stop steel plate 40 to extend into the cavity 11. The limiting components are symmetrically arranged in multiple ways along the center of the box body. Each limiting component includes a limiting block 21 disposed in the cavity 11 and a fastener 22 disposed on the side of the box body 10 away from the limiting block 21 and movable relative to the side of the box body 10, so that a limiting area of ​​different sizes is formed between the fastener 22 and the limiting block 21 along the width direction of the waterstop steel plate 40. The glue injection assembly is used to fill the cavity 11 with waterproof sealant, including a glue injection part located at the bottom of the box 10 and a glue dispensing part located at the top of the box 10.

[0026] Specifically, the shape of the interlocking joint 12 is adapted to the cross-sectional shape of the waterstop steel plate 40, and the diameter of the interlocking joint 12 is greater than or equal to the cross-sectional width of the waterstop steel plate 40. In this example, the diameter of the joint 12 is equal to the cross-sectional width of the waterstop steel plate 40.

[0027] For example, the two waterstop steel plates 40 to be connected are C-shaped; the insertion joint 12 is also C-shaped, including an upper inclined section 121, a vertical section 122 and a lower inclined section 123 connected in sequence, and the installation height of the limiting block 21 is within the height range of the vertical section 122 of the insertion joint 12.

[0028] For example, the limiting block 21 is a support column set on the inner wall of the back of the box 10, and the fastener 22 is a bolt set on the front of the box 10 and threadedly connected to the front of the box 10, corresponding to the support column; in this example, four limiting components are provided, including two limiting components set on the left side of the box 10 and two limiting components set on the right side of the box 10, wherein the two limiting components on the left side of the box 10 and the two limiting components on the right side of the box 10 are distributed vertically at intervals, and the limiting components on the left and right sides of the box 10 are symmetrically distributed along the center line of the box 10.

[0029] Specifically, the horizontal projection of the end of the limiting block 21 away from the side of the box 10 and the horizontal projection of the corresponding insertion joint 12 near the support column are on the same plane. This makes it so that during the installation of the waterstop steel plate 40, when the fastener 22 and the limiting block 21 are used to fix the relative position of the waterstop steel plate 40 and the box 10, one side of the waterstop steel plate 40 is simultaneously pressed against the end of the limiting block 21 away from the box 10 and the side of the insertion joint 12 near the limiting block 21.

[0030] Specifically, the distance between the top of the insertion joint 12 and the top surface of the cavity 11, and the distance between the bottom of the insertion joint 12 and the bottom surface of the cavity 11, are both 1-3cm, so as to leave enough flow space for the filling of waterproof sealant.

[0031] For example, the vertical projections of the glue injection section and the glue dispensing section are located at opposite ends of the box body 10. The glue injection section is located on the bottom left side of the box body 10, and includes a glue injection hole 311 and a glue injection tube 312 with the same diameter as the glue injection hole 311, which is disposed at and communicates with the glue injection hole 311. The glue dispensing section is located on the top right side of the box body 10, and includes a glue dispensing hole 321 and a glue dispensing tube 322 with the same diameter as the glue dispensing hole 321, which is disposed at and communicates with the glue dispensing hole 321. The glue injection tube 312 and the glue dispensing tube 322 are conveniently connected to the tube body of the glue injection equipment for glue injection processing.

[0032] Specifically, the box 10 is rectangular; the material of the box 10 is iron plate; for example, the box 10 is an integrated structure made of iron plate with a thickness of 3mm.

[0033] In use, the connecting ends of the two water-stop steel plates 40 are extended into the cavity 11 through the insertion seams 12 on both sides of the box body 10, and the left water-stop steel plate is made to pass over the left limiting block, and the right water-stop steel plate is made to pass over the right limiting block; the fasteners 22 are adjusted so that a limiting area equal to the width of the water-stop steel plate 40 is formed between the fasteners 22 and the limiting block 21. At this time, one side of the water-stop steel plate 40 is simultaneously pressed against the end of the limiting block 21 away from the box body 10 and the side of the insertion seam 12 close to the limiting block 21, so that the water-stop steel plate 40 and the box body 10 remain relatively fixed. The two limiting components on the left side of the box 10 are used to fix the relative position of the left water-stop steel plate 40 and the box 10, and the two limiting components on the right side of the box 10 are used to fix the relative position of the right water-stop steel plate 40 and the box 10. Then, the glue injection pipe 312 and the glue outlet pipe 322 are connected to the glue injection equipment to fill the cavity 11 with waterproof sealant. The waterproof sealant serves to seal and stop water, and also strengthens the connection between the two water-stop steel plates 40 to a certain extent. A schematic diagram of the waterproof sealant filling is shown below. Figure 3 As shown in this example, the waterproof sealant is epoxy resin. When the epoxy resin overflows from the dispensing tube 322, the dispensing is complete. During the dispensing process, the dispensing tube 322 serves as an indicator of whether the dispensing is complete. Afterwards, once the adhesive has cured, the connection between the two waterstop steel plates at their 40mm ends is complete.

[0034] Regarding the length of the waterstop steel plate 40 extending into the cavity 11, the length of the waterstop steel plate 40 from the side closest to the center of the cavity 11 to the side of the cavity 11 should be greater than or equal to the length of the limiting block 21 to the side of the cavity 11, so that the waterstop steel plate can be tightly attached to the limiting block 21.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
