Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a water-stopping steel plate structure at corners. Background Technology

[0002] In basement post-pouring strips and construction joints, the common practice is to embed water-stop steel plates. However, traditional water-stop steel plate installation involves on-site welding. Due to the complex on-site construction environment, especially at the overlapping parts of non-straight sections of the water-stop steel plates, which involve internal corners, external corners, "T" shapes, and high-low span overlaps, inconvenient construction operations often result in incomplete welding or missed welds. This causes the water-stop steel plates to fail to meet the required water-stopping effect, creating a potential leakage hazard. Summary of the Invention

[0003] In view of this, the present invention discloses a corner waterstop steel plate structure, the purpose of which is to solve the problem that the overlapping parts of the non-straight section waterstop steel plate welded on site are prone to leakage.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A corner-stopping steel plate structure includes a steel plate body, a flexible corner connector, and a support structure. Each corner connector has a vertical mounting groove, within which a connecting plate is installed. Each connecting plate has a connecting groove at its end that engages with the steel plate body. The support structure includes a base, with support rods at both ends. The length of each support rod is adjustable, and each end of the support rod is hinged to a mounting seat, which is detachably connected to the side wall of the corresponding connecting plate. A support rod slidably mounted on the base, facing the corner connector, is provided with a pin to restrict the sliding of the support rod. The end of the support rod has a clamping structure that abuts against the corner connector.

[0006] During construction, the connecting plate is placed in the mounting groove of the corner connector, and the waterstop steel plate body is inserted into the slot of the connecting plate. Then, the corner connector is bent to the required angle, the length of the support rod is adjusted, and the mounting seat at the end of the support rod is installed and fixed to the connecting plate. At this time, the support rod is slid, and the clamping structure at the end of the support rod abuts against the corner connector to prevent the bending angle of the corner connector from changing during construction and affecting the construction quality. In this solution, the flexibility and bendability of the rotating shaft connector can be used to bend according to the angle of the non-straight section to meet the installation requirements of the waterstop steel plate. At the same time, compared with the traditional welding process, the construction of this solution is more convenient and will not cause leakage risks due to incomplete welding or missed welding.

[0007] Furthermore, the clamping structure includes a base fixed to the end of the support rod. The end face of the base has several grooves facing the corner connector. Each groove is slidably connected to a clamping block. An elastic support is provided between the clamping block and the groove. The upper end of the base has a cavity. A fastening block is provided in the cavity. The fastening block has several protrusions extending into the corresponding grooves. Each clamping block has several cavities at its upper end that cooperate with the protrusions.

[0008] In this design, the support rod pushes the base to slide towards the corner connector, causing the abutment block on the base to abut against the curved part of the corner connector. The corner connector pushes the abutment block to slide into the groove, so that the ends of the numerous abutment blocks are all in contact with the corner connector. At this time, the fastening block is installed, and the protrusion on the fastening block extends into the groove and engages with the cavity, thereby restricting the abutment block. In turn, the abutment block forms a stable support for the corner connector, preventing the curved part of the corner connector from deforming and affecting the water-stopping effect of the water-stop steel plate.

[0009] In addition, when the corner connector is not curved, the abutment block can be slid in advance to form the desired shape at the end of the abutment block. Then, the fastening block is installed to fix the abutment block, and the abutment block is used to abut against the corner connector to bend the corner connector into the desired shape.

[0010] Furthermore, the corner connector has a cavity inside, and several vertically arranged support shafts are arranged inside the cavity. Both ends of the support shafts are rotatably connected to the corresponding inner wall of the cavity. Several rotating blocks are fixed on the support shafts. Both ends of the rotating blocks are provided with coaxial arc grooves. A connecting rod is arranged between horizontally adjacent rotating blocks. The end of the connecting rod is fixed with a first arc block that is slidably connected to the corresponding arc groove. The support shaft is provided with a limiting structure for restricting the rotation of the first arc block.

[0011] When the corner connector bends, the adjacent support shafts deflect. At this time, the connecting rod between the adjacent rotating blocks drives the first arc block to slide in the corresponding arc groove until the corner connector bends to the required degree. At this time, the rotation of the first arc block is restricted by the limiting structure. The support shaft and connecting rod form an internal stable support for the corner connector to prevent the corner connector from deforming during subsequent use.

[0012] Furthermore, the limiting structure includes several annular blocks disposed below the rotating block. Each annular block is slidably connected to its corresponding support shaft. Both ends of each annular block are also provided with coaxial arc-shaped grooves. A synchronizing rod is provided between horizontally adjacent annular blocks. The end of each synchronizing rod is fixed with a second arc-shaped block that is slidably connected to its corresponding arc-shaped groove. Each rotating block has several arc-shaped through holes at its bottom, and these through holes are connected to its corresponding arc-shaped grooves. Each first arc-shaped block has a locking hole at its bottom. Each annular block has an arc-shaped through groove at its top that communicates with its corresponding arc-shaped groove. A locking rod is fixed at the top of each second arc-shaped block, passing through the through groove and through hole and engaging with the locking hole.

[0013] When the first annular block slides, the second arc-shaped blocks at both ends of the synchronizing rod move synchronously. When the corner connector bends to the required degree, the annular block at the upward sliding end moves synchronously upward with the synchronizing rod until the locking rod is inserted into the locking hole through the corresponding through hole, thereby restricting the sliding of the first and second arc-shaped blocks and maintaining stable support for the inside of the corner connector.

[0014] Furthermore, each of the mounting slots has a vertically oriented groove, and each groove has a number of vertically slidable adjustment rods, the ends of which extend into the cavity and are connected to the corresponding annular blocks.

[0015] Furthermore, adhesive is provided at the connection point between the connecting groove and the steel plate body.

[0016] Furthermore, the cavity is filled with powdered concrete.

[0017] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0024] like Figures 1-4 As shown:

[0025] A corner-stopping steel plate structure includes a steel plate body 1, a flexible corner connector 2, and a support structure. Each corner connector 2 has a vertical mounting groove, within which a connecting plate 3 is installed. Each end of the connecting plate 3 has a connecting groove that engages with the steel plate body 1. The support structure includes a base 4, with support rods 5 at both ends. The length of the support rods 5 is adjustable. In this embodiment, the support rods 5 are telescopic rods with a self-locking function. Each end of the support rod 5 is hinged to a mounting seat 6, which is detachably connected to the side wall of the corresponding connecting plate 3. A support rod 7 is slidably mounted on the base 4, facing the corner connector 2. The base 4 has a pin to restrict the sliding of the support rod 7, and the end of the support rod 7 has a clamping structure that abuts against the corner connector 2.

[0026] During construction, the connecting plate 3 is placed in the mounting groove of the corner connector 2, and the waterstop steel plate body 1 is inserted into the slot of the connecting plate 3. Then, the corner connector 2 is bent to the required angle, the length of the support rod 5 is adjusted, and the mounting seat 6 at the end of the support rod 5 is installed and fixed to the connecting plate 3. At this time, the support rod 7 is slid, and the clamping structure at the end of the support rod 7 abuts against the corner connector 2 to prevent the bending angle of the corner connector 2 from changing during construction and affecting the construction quality. In this solution, the flexibility and bendability of the shaft connector can be used to bend according to the angle of the non-straight section to meet the installation requirements of the waterstop steel plate. At the same time, compared with the traditional welding process, the construction of this solution is more convenient and will not cause leakage risks due to incomplete welding or missed welding.

[0027] In this embodiment, the clamping structure includes a base 8 fixed to the end of the support rod 7. The end face of the base 8 is provided with a plurality of sliding grooves facing the corner connector 2. Each sliding groove is slidably connected to a clamping block 9. An elastic support 10 is provided between the clamping block 9 and the sliding groove. The upper end of the base 8 is provided with a cavity. A fastening block 11 is provided in the cavity. The fastening block 11 is provided with a plurality of protrusions 12 extending into the corresponding sliding grooves. Each upper end of the clamping block 9 is provided with a plurality of cavities that cooperate with the protrusions 12.

[0028] In this scheme, the support rod 7 pushes the base 8 to slide towards the corner connector 2, so that the abutment block 9 on the base 8 abuts against the bent part of the corner connector 2. The corner connector 2 pushes the abutment block 9 to slide into the groove, so that the ends of the numerous abutment blocks 9 are all in contact with the corner connector 2. At this time, the fastening block 11 is installed. The protrusion 12 on the fastening block 11 extends into the groove and engages with the cavity, thereby restricting the abutment block 9. In this way, the abutment block 9 forms a stable support for the corner connector 2, preventing the bent part of the corner connector 2 from deforming and affecting the water-stopping effect of the water-stopping steel plate.

[0029] In addition, when the corner connector 2 is not curved, the clamping block 9 can be slid beforehand so that the end of the clamping block 9 forms the required shape. Then, the fastening block 11 is installed to fix the clamping block 9, and the clamping block 9 is used to abut against the corner connector 2 so that the corner connector 2 is bent into the required shape.

[0030] In this embodiment, the corner connector 2 has a cavity inside, and a plurality of vertically arranged support shafts 13 are arranged inside the cavity. Both ends of the support shafts 13 are rotatably connected to the corresponding inner wall of the cavity. A plurality of rotating blocks 14 are fixed on each support shaft 13. Both ends of each rotating block 14 are provided with coaxial arc grooves. A connecting rod 15 is arranged between horizontally adjacent rotating blocks 14. The end of each connecting rod 15 is fixed with a first arc block 16 that is slidably connected to the corresponding arc groove. The support shaft 13 is provided with a limiting structure for restricting the rotation of the first arc block 16.

[0031] When the corner connector 2 bends, the adjacent support shafts 13 deflect. At this time, the connecting rod 15 between the adjacent rotating blocks 14 drives the first arc block 16 to slide in the corresponding arc groove until the corner connector 2 bends to the required degree. At this time, the rotation of the first arc block 16 is restricted by the limiting structure. The support shafts 13 and connecting rods 15 form an internal stable support for the corner connector 2 to prevent the corner connector 2 from deforming during subsequent use.

[0032] In this embodiment, the limiting structure includes several annular blocks 17 disposed below the rotating block 14. Each annular block 17 is slidably connected to the corresponding support shaft 13. Both ends of each annular block 17 are also provided with coaxial arc-shaped grooves. A synchronizing rod 18 is provided between horizontally adjacent annular blocks 17. The ends of each synchronizing rod 18 are fixed with a second arc-shaped block 19 that is slidably connected to the corresponding arc-shaped groove. Each rotating block 14 has several arc-shaped through holes at its bottom, and the through holes are connected to the corresponding arc-shaped grooves. Each first arc-shaped block 16 has a locking hole 21 at its bottom. Each annular block 17 has an arc-shaped through groove that communicates with the corresponding arc-shaped groove at its top. The top of each second arc-shaped block 19 is fixed with a locking rod 20 that passes through the through groove and through hole and engages with the locking hole 21.

[0033] When the first annular block 17 slides, the second arc-shaped blocks 19 at both ends of the synchronizing rod 18 move synchronously. When the corner connector 2 bends to the required degree, the annular block 17 at the upward sliding end moves synchronously upward with the synchronizing rod 18 until the locking rod 20 is inserted into the locking hole 21 through the corresponding through hole, thereby restricting the sliding of the first arc-shaped block 16 and the second arc-shaped block 19, and thus maintaining stable support for the inside of the corner connector 2.

[0034] In this embodiment, each of the mounting slots is vertically formed with a groove body, and each of the groove bodies is vertically slidably provided with a plurality of control rods 22. The ends of the control rods 22 extend into the cavity and are welded and fixed to the corresponding annular blocks 17.

[0035] The ring block 17 can be moved by adjusting the lever 22, making the operation simple and convenient.

[0036] In this embodiment, the connection between the connecting groove and the steel plate body 1 is provided with adhesive to prevent leakage at the connection.

[0037] In this embodiment, the cavity is filled with powdered concrete.

[0038] After the supporting structure is installed but before the steel plate body 1 is installed, powdered concrete is filled into the cavity through the trench and the trench is sealed (a conventional technical method, so it is not described in detail) to fill the cavity and prevent the corner connector 2 from collapsing inward.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
