Description

Technical Field

[0001] This utility model relates to the field of construction waterproofing technology, specifically to a waterproofing structure for construction joints. Background Technology

[0002] A construction joint is a joint formed between concrete poured in stages due to design requirements or construction needs. It is not a real "seam" but rather a bonding surface between the first and second poured concrete after the first poured concrete has exceeded its initial setting time. To prevent leakage at construction joints, waterproof structures are usually used to cover them.

[0003] The prior art patent CN219909449U discloses a construction joint waterproofing structure. This structure, through the arrangement of a rod, spring, and slot, allows the connecting block to be inserted into the outside of a T-shaped block during installation. Then, under the elastic action of the spring, the limiting block and the rod are pulled towards one side of the slot, allowing the rod to be inserted into the slot, thus fixing the connecting block and the T-shaped block. This makes the installation of the connecting block convenient and quick, improving the construction efficiency of the entire construction joint waterproofing structure. However, during installation, if the pressure applied by the connecting block to the waterstop is too small, the waterstop may not fit tightly against the construction joint, resulting in poor sealing. Conversely, if the pressure applied by the connecting block to the waterstop is too large, it not only increases the installation difficulty of the connecting block and the waterstop but may even prevent proper installation. Further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a waterproof structure for construction joints. This structure solves the problem that if the pressure exerted by the connecting block on the waterstop is too small, the waterstop will not be able to fit tightly with the construction joint, resulting in poor sealing effect. Conversely, if the pressure is too large, it will increase the difficulty of installation and may even prevent normal installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a construction joint waterproof structure, comprising a first wall, a second wall, and a waterstop plate, wherein multiple L-shaped fixing plates are fixedly provided on both the first wall and the second wall, and an installation component for fixing the waterstop plate is connected to every two corresponding L-shaped fixing plates. The installation assembly includes an adjustable slide plate connected to the top of the waterstop plate. A control screw is rotatably mounted on the top of the adjustable slide plate. A movable plate is threaded onto the control screw. Two horizontal sliding sleeves are slidably fitted onto the movable plate. A positioning rod is fixedly provided on the top of each of the two horizontal sliding sleeves. A positioning hole is opened on the top of each of the two L-shaped fixing plates. The top ends of the two positioning rods slide through the two positioning holes respectively. A compression spring is fixedly provided on the top of each of the two horizontal sliding sleeves. The top ends of the two compression springs are respectively abutted against the bottom inner wall of the two L-shaped fixing plates. A locking unit is installed on each of the two horizontal sliding sleeves.

[0006] Preferably, the locking unit includes a first bolt, a first threaded hole is provided on the side of the horizontal sliding sleeve, the first bolt is threadedly installed in the first threaded hole, and the end of the first bolt abuts against the side of the moving plate.

[0007] Preferably, the top of the waterstop plate has two T-shaped grooves, the bottom of the adjustable slide plate has two T-shaped slide bars fixedly installed, the two T-shaped slide bars are slidably installed in the two T-shaped grooves respectively, the top of the adjustable slide plate has two second screw holes, each of the two second screw holes has a second bolt threaded in it, and the bottom ends of the two second bolts abut against the top of the waterstop plate.

[0008] Preferably, two guide rods are fixedly installed on the top of the adjustable slide plate, and two guide holes are opened on the top of the movable plate, with the two guide rods slidably installed in the two guide holes respectively.

[0009] Preferably, multiple embedded plates are pre-installed in both the first wall and the second wall, and the multiple L-shaped fixing plates are respectively fixed on the top of the multiple embedded plates.

[0010] Preferably, one end of the waterstop plate has two connecting holes, and the other end of the waterstop plate is fixed with two connecting rods, each of which is adapted to one of the two connecting holes.

[0011] Preferably, a plurality of rubber waterstop strips are uniformly fixed to the bottom of the waterstop plate.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model, through the setting of the installation components, allows the control screw to rotate and move the horizontal sliding sleeve and positioning rod up and down via the moving plate after the waterstop plate is placed over the construction joint between the first and second walls. When the positioning rod moves upward and inserts into the positioning hole, the moving plate can continue to rise and compress the compression spring through the horizontal sliding sleeve. At this time, under the elastic force of the compression spring, a downward compressive force is applied to the horizontal sliding sleeve. This force is further transmitted to the waterstop plate through the moving plate, control screw, and adjustable slide plate, which in turn compresses the waterstop plate downward to make it fit tightly against the first and second walls. As the compression spring is continuously compressed, the compressive force applied to the waterstop plate continuously increases, thereby ensuring that the waterstop plate can firmly seal the construction joint between the first and second walls, with excellent waterproof sealing effect. Moreover, the entire installation process is simple to operate and greatly improves installation efficiency. 2. This utility model uses a combination of a horizontal sliding sleeve, a first bolt, an adjustable sliding plate, and a second bolt. When the second bolt is rotated, it will either tighten or loosen the adjustable sliding plate, allowing the horizontal position of the movable plate to be adjusted by sliding the adjustable sliding plate. When the first bolt is rotated, it will either tighten or loosen the horizontal sliding sleeve, allowing the position of the positioning rod to be adjusted by moving the horizontal sliding sleeve. This allows the waterstop plate to be installed at different L-shaped fixing plates, improving adaptability. Attached Figure Description

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 4 The present invention will be further described below.

[0017] A construction joint waterproofing structure includes a first wall 1, a second wall 2, and a waterstop 3. A construction joint is formed between the first wall 1 and the second wall 2. The waterstop 3 covers the construction joint and is attached to the top of the first wall 1 and the second wall 2. Multiple L-shaped fixing plates 4 are fixed on both the first wall 1 and the second wall 2. An installation component for fixing the waterstop 3 is connected to each pair of corresponding L-shaped fixing plates 4. The mounting assembly includes an adjustable slide plate 6 connected to the top of the waterstop plate 3. A control screw 5 is rotatably mounted on the top of the adjustable slide plate 6. A hexagonal head is fixed to the top of the control screw 5. A movable plate 7 is threaded onto the control screw 5. Two guide rods 14 are fixedly mounted on the top of the adjustable slide plate 6. Two guide holes are opened on the top of the movable plate 7. The two guide rods 14 are slidably installed in the two guide holes respectively. Through the cooperation of the guide rods 14 and the guide holes, the movable plate 7 can only move up and down and will not rotate with the control screw 5. A baffle is fixed to the top of the guide rod 14. Two horizontal sliding sleeves 8 are slidably sleeved on the movable plate 7. A positioning insert 9 is fixed to the top of each of the two horizontal sliding sleeves 8. A positioning insertion hole is opened on the top of each of the two L-shaped fixed plates 4. The tops of the two positioning inserts 9 slide through the two positioning insertion holes respectively. A compression spring 10 is fixed to the top of each of the two horizontal sliding sleeves 8. The tops of the two compression springs 10 are respectively attached to the bottom inner wall of the two L-shaped fixed plates 4. A locking unit is installed on each of the two horizontal sliding sleeves 8.

[0018] Specifically, when the control screw 5 is rotated, the guide rod 14 guides the moving plate 7 to move up and down, which in turn moves the horizontal sliding sleeve 8 and the positioning rod 9 up and down together. When the positioning rod 9 moves upward and is inserted into the positioning hole, if the moving plate 7 is continued to move upward, the horizontal sliding sleeve 8 will compress the compression spring 10. At this time, under the elastic force of the compression spring 10, a downward compressive force will be applied to the horizontal sliding sleeve 8. This force will be further transmitted to the adjustable slide plate 6 through the moving plate 7 and the control screw 5, thereby compressing the waterstop plate 3 downward. This will make the waterstop plate 3 fit tightly against the first wall 1 and the second wall 2. As the compression spring 10 is continuously compressed, the compressive force applied to the waterstop plate 3 will continue to increase, thus ensuring that the waterstop plate 3 can firmly seal the construction joint between the first wall 1 and the second wall 2. The waterproof sealing effect is excellent, and the entire installation process is simple to operate, greatly improving the installation efficiency.

[0019] like Figure 3 As shown, the locking unit includes a first bolt 11, and a first screw hole is provided on the side of the horizontal sliding sleeve 8. The first bolt 11 is threaded into the first screw hole, and the end of the first bolt 11 abuts against the side of the moving plate 7.

[0020] Specifically, when the first bolt 11 is rotated, the first bolt 11 will be displaced while rotating due to the action of the first screw hole, which can then tighten or loosen the horizontal sliding sleeve 8 against the moving plate 7. When the horizontal sliding sleeve 8 is in the loosened state, the horizontal sliding sleeve 8 can be moved to adjust the position of the positioning rod 9.

[0021] like Figure 2 and Figure 3 As shown, the top of the waterstop plate 3 has two T-shaped grooves, and the bottom of the adjustable slide plate 6 has two T-shaped slide bars 12 fixedly installed. The two T-shaped slide bars 12 are slidably installed in the two T-shaped grooves respectively. The top of the adjustable slide plate 6 has two second screw holes, and the two second screw holes are threaded with second bolts 13. The bottom ends of the two second bolts 13 abut against the top of the waterstop plate 3.

[0022] Specifically, when the second bolt 13 is rotated, the adjustable slide plate 6 will be tightened or loosened under the action of the second screw hole. When the adjustable slide plate 6 is in the loose state, the position of the adjustable slide plate 6 and the movable plate 7 can be adjusted along the length direction of the waterstop plate 3 with the cooperation of the T-shaped slide groove and the T-shaped slide bar 12.

[0023] like Figure 2As shown, multiple embedded plates 15 are pre-installed in both the first wall 1 and the second wall 2, and multiple L-shaped fixing plates 4 are fixed on the top of the multiple embedded plates 15. By setting the embedded plates 15, the load on the L-shaped fixing plates 4 can be effectively transferred to the first wall 1 or the second wall 2, thereby improving the load-bearing strength and reliability of the L-shaped fixing plates 4.

[0024] like Figure 4 As shown, two connecting holes are provided at one end of the waterstop plate 3, and two connecting rods 16 are fixed at the other end of the waterstop plate 3. The two connecting rods 16 correspond to the positions of the two connecting holes and are matched in size.

[0025] Specifically, when the connecting rod 16 on one of the waterstop plates 3 is inserted into the connecting hole on another waterstop plate 3, the two waterstop plates 3 can be positioned and connected together, which makes it convenient to connect multiple waterstop plates 3 in sequence to adapt to sealing construction joints of different lengths.

[0026] like Figure 2 and Figure 4 As shown, multiple rubber waterstop strips 17 are evenly fixed to the bottom of the waterstop plate 3. The setting of the rubber waterstop strips 17 can effectively increase the sealing between the waterstop plate 3 and the first wall 1 and the second wall 2, and further improve the sealing and waterproofing effect of the construction joint.

[0027] In summary: When using this utility model, first take the waterstop plate 3 and cover it on the construction joint between the first wall 1 and the second wall 2. Then, rotate the second bolt 13 to loosen the adjustable slide plate 6. At this time, the adjustable slide plate 6 can be slid until the moving plate 7 is directly below the L-shaped fixed plate 4. Then, reverse the second bolt 13 to fix the adjustable slide plate 6. Next, rotate the first bolt 11 to loosen the horizontal sliding sleeve 8. At this time, the horizontal sliding sleeve 8 can be moved until the positioning rod 9 is directly below the positioning hole. Then, reverse the first bolt 11 to fix the horizontal sliding sleeve 8. Finally, the control screw 5 can be rotated directly. Under the guidance of the guide rod 14, the rotation of the control screw 5 will drive the moving plate 7 to move up and down. The up and down movement of the moving plate 7 will drive the horizontal sliding sleeve 8 and the positioning rod 9 to move up and down together. After the insertion rod 9 moves upward and is inserted into the positioning hole, the control screw 5 can be rotated to move the moving plate 7 upward. At this time, the upward movement of the moving plate 7 will compress the compression spring 10 through the horizontal sliding sleeve 8. Under the elastic force of the compression spring 10, a downward compressive force will be applied to the horizontal sliding sleeve 8. This force will be further transmitted to the waterstop plate 3 through the moving plate 7, the control screw 5 and the adjustable slide plate 6, pressing it downward. This will make the waterstop plate 3 fit tightly against the first wall 1 and the second wall 2. As the compression spring 10 is continuously compressed, the compressive force applied to the waterstop plate 3 will continue to increase, thereby ensuring that the waterstop plate 3 can firmly seal the construction joint between the first wall 1 and the second wall 2. The waterproof sealing effect is excellent, and the entire installation process is simple to operate, greatly improving the installation efficiency.

Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
