Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, to a tool for installing joint panels. Background Technology

[0002] Water-resistant walls are a key structure for flood-prone pavements. Their core function is to block water seepage into the pavement and prevent water erosion of the roadbed. Water-resistant walls are generally made of plain concrete. Settlement joints are structures designed to prevent cracks in the water-resistant wall structure due to uneven settlement and temperature deformation. Settlement joints are typically placed every few meters in the water-resistant wall. Jointing boards are filling materials embedded in the settlement joints. Their function is to support the walls on both sides of the joint, prevent debris from entering the joint, and accommodate the deformation of the joint to ensure that the settlement joint functions effectively.

[0003] Common jointing panels are made of polyethylene. However, due to the softness of polyethylene, these panels are difficult to fix during concrete pouring and are prone to bending and displacement under the pressure of the concrete, failing to achieve the desired jointing effect. Therefore, improving the installation stability of jointing panels is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The problem this invention addresses is: how to improve the installation stability of the joint panel.

[0005] To solve the above problems, this utility model provides a joint panel installation tool, comprising:

[0006] Two first plates, each first plate including two first main planes arranged opposite to each other, the two first plates being arranged at intervals, and a joint plate being placed between the first main planes of the two first plates;

[0007] A connecting portion is provided on the same side of the two first plates, one end of the connecting portion is connected to the side end of one of the first plates, and the other end of the connecting portion is connected to the side end of the other first plate.

[0008] The lifting part is connected to the top of the first plate.

[0009] Optionally, in the vertical direction, the height of the connecting portion is less than the height of the first plate; the orthographic projection of the connecting portion on the first plate is spaced apart from the bottom surface of the first plate.

[0010] Optionally, the first plate is provided with a first hollow portion, which penetrates the first plate along the thickness direction of the first plate.

[0013] Optionally, the distance between the corresponding top ends of the two first plates is greater than the distance between the corresponding bottom ends of the two first plates.

[0014] Optionally, each of the first plates has a corresponding lifting portion at its top end, the extension direction of the lifting portion being parallel to the extension direction of the top surface of the first plate, and the two ends of the lifting portion extending beyond the two side ends of the first plate respectively.

[0015] Optionally, the surface of the lifting part near the bottom edge of the first plate is provided with an anti-slip pattern; and / or, the surface of the lifting part near the bottom edge of the first plate is provided with a gripping groove.

[0016] Optionally, the joint panel installation tool further includes a level corresponding to the lifting part to assist the joint panel installation tool in maintaining a vertical upward lifting motion.

[0017] Optionally, the level is disposed on the surface of the lifting portion on the side away from the bottom edge of the first plate.

[0018] The beneficial effects of this joint panel installation tool are as follows: Two first plates, spaced apart on corresponding planes, are connected by a connecting part, with a lifting part at the top of each first plate. After the concrete formwork is installed, the joint panel installation tool is placed at the designated location where the joint panel needs to be installed. The joint panel is inserted between the two first plates of the tool, with the gap between the two first plates forming a limiting position. Simultaneously, the connecting part ensures a stable gap between the two first plates, ensuring the initial position of the joint panel is accurate. Concrete is poured in layers on both sides of the tool, and the tool is gradually lifted vertically upwards using the top lifting part. During this process, the joint panel remains fixed due to the initial encapsulation by the concrete. The tool is then gradually withdrawn from the concrete. As the tool is withdrawn, the concrete sequentially encapsulates the bottom, middle, and top of the joint panel, gradually increasing the encapsulation area and fixing force, ensuring accurate positioning and verticality of the joint panel, meeting construction requirements, and improving the installation stability of the joint panel.

[0033] In related technologies, the water-resistant wall is a key structure for flood-crossing pavements, its core function being to block water seepage and prevent water erosion of the roadbed. Water-resistant walls are typically made of plain concrete. Settlement joints are structures designed to prevent cracks in the water-resistant wall structure due to uneven settlement and temperature deformation. Settlement joints are generally placed every few meters in the water-resistant wall. Jointing panels are filling materials embedded in the settlement joints, their function being to support the walls on both sides of the joint, prevent debris from entering the joint, and accommodate joint deformation to ensure the effective functioning of the settlement joint. Jointing panels are generally made of polyethylene. However, because polyethylene is soft, it is difficult to fix during concrete pouring, and it is prone to bending and displacement under the pressure of concrete, failing to achieve the desired jointing effect. Therefore, how to improve the installation stability of jointing panels is a technical problem that urgently needs to be solved by those skilled in the art.

[0034] To address the problems existing in the aforementioned related technologies, this utility model provides a jointing board installation tool 10. Two first plates 20 are arranged at intervals relative to each other, and a connecting part 30 connects the two first plates 20. A lifting part 40 is provided at the top of each first plate 20. After the concrete formwork is installed, the jointing board installation tool 10 is placed at the designated position where the jointing board 11 needs to be installed. The jointing board 11 is inserted between the two first plates 20 of the jointing board installation tool 10, and the interval between the two first plates 20 forms a limiting force to ensure the accurate initial position of the jointing board 11. Concrete is poured in layers on both sides of the jointing board installation tool 10, while simultaneously... The joint panel installation tool 10 is gradually pulled vertically upward through the top lifting part 40, so that the joint panel installation tool 10 is gradually removed from the concrete. As the joint panel installation tool 10 is removed, the concrete will successively wrap around the bottom, middle and top of the joint panel 11, and the wrapping area and fixing force of the joint panel 11 will gradually increase until the joint panel installation tool 10 is completely removed from the joint panel 11. At this time, the joint panel 11 is completely wrapped by the concrete. During this process, due to the limiting of the joint panel installation tool 10, the position of the joint panel 11 is accurate and the panel is vertical, which meets the construction requirements and improves the installation stability of the joint panel 11.

[0035] The following detailed description is based on specific embodiments.

[0036] Combination Figures 1 to 8 As shown, the joint panel installation tool 10 provided in this embodiment of the present invention includes two first plates 20, a connecting part 30, and a lifting part 40. The first plates 20 include two first main planes 21 arranged opposite to each other. The two first plates 20 are arranged at intervals corresponding to the first main planes 21, and the joint panel 11 is placed between the first main planes 21 of the two first plates 20. The connecting part 30 is located on the same side of the two first plates 20. One end of the connecting part 30 is connected to the side end of one of the first plates 20, and the other end of the connecting part 30 is connected to the side end of the other first plate 20. The lifting part 40 is connected to the top end of the first plate 20.

[0037] Understandably, please refer to the details. Figure 1 , Figure 2The jointing board installation tool 10 includes two first plates 20. Each first plate 20 includes two opposing first main planes 21, two opposing first side planes 22, and opposing first top surface 23 and first bottom surface 24. The two first plates 20 are spaced apart, and a first slit 26 is formed between the opposing first main planes 21 for positioning the jointing board 11. One end of the connecting part 30 is connected to the side end of one of the first plates 20, and the other end of the connecting part 30 is connected to the side end of the other first plate 20 to ensure a stable relative position between the two first plates 20. After the concrete formwork is installed, the jointing board installation tool 10 is placed at the designated position where the jointing board 11 needs to be installed (i.e., the corresponding settlement joint), and the jointing board 11 is inserted into the first slit 26 between the two first plates 20 of the jointing board installation tool 10 to ensure that the initial position of the jointing board 11 is accurate. The lifting part 40 is connected to the top of the first plate 20, making it convenient for operators to lift the lifting part 40. Concrete is poured in layers on both sides of the joint plate installation tool 10. At the same time, the joint plate installation tool 10 is gradually lifted vertically upward through the top lifting part 40. During this process, the bottom end of the joint plate 11 can be initially wrapped and fixed by the concrete. The joint plate installation tool 10 is gradually withdrawn from the concrete. As the joint plate installation tool 10 is withdrawn, the concrete will successively wrap the bottom end, middle and top of the joint plate 11, gradually increasing the wrapping area and fixing force of the joint plate 11. During this process, the joint plate installation tool 10 always has a limiting effect on the joint plate 11, ensuring that the joint plate 11 is accurately positioned and the plate is vertical, meeting the construction requirements and improving the installation stability of the joint plate 11.

[0038] In the attached figures, the first side surface 22 corresponds to the position of the side end of the first plate 20, the first top surface 23 corresponds to the position of the top end of the first plate 20, and the first bottom surface 24 corresponds to the position of the bottom end of the first plate 20.

[0039] Specifically, the material of the first plate 20 can be a steel plate.

[0040] In some embodiments, please refer to the following for details. Figures 1 to 8 Each of the first plates 20 has a corresponding lifting part 40 at its top end. The extending direction of the lifting part 40 is parallel to the extending direction of the top surface of the first plate 20, and the two ends of the lifting part 40 extend beyond the two side ends of the first plate 20 respectively.

[0041] The extension direction of the pull part 40 is parallel to the extension direction of the top surface of the first plate 20, that is, the pull part 40 extends horizontally. One end of the pull part 40 extends away from the center of the first plate 20, and both ends of the pull part 40 extend beyond the two side ends of the first plate 20. The pull part 40 extends beyond the outer edge of the first plate 20, which makes it easy to hold and pull vertically upward. This helps to maintain the horizontal state of the pull part 40 during the lifting process, that is, to ensure the accuracy and stability of the vertical movement of the joint panel installation tool 10, and to ensure that the joint panel 11 is accurately positioned and the panel is vertical.

[0042] In some embodiments, please refer to the following for details. Figure 1 The two first plates 20 are arranged in parallel. The two first plates 20 are arranged in parallel with a gap between them, and the corresponding first main planes 21 of the two first plates 20 are arranged in parallel to form a gap that matches the thickness of the joint plate 11. After the joint plate 11 is inserted, it can be firmly held in place by the two side plates, directly avoiding the tilting or displacement of the joint plate 11 caused by external forces such as the impact of concrete pouring during installation.

[0043] In some embodiments, please refer to the following for details. Figure 1 In the vertical direction, the height of the connecting part 30 is less than the height of the first plate 20; the orthographic projection of the connecting part 30 on the first plate 20 is spaced apart from the bottom surface of the first plate 20. That is, the orthographic projection of the connecting part 30 on the first plate 20 is spaced apart from the first bottom surface 24. The stability of the joint plate 11 starts from the bottom. The bottom needs to be tightly wrapped with concrete first to avoid tilting or displacement during subsequent pouring. The connecting part 30 is only correspondingly set in the upper middle part of the first plate 20 and does not extend to the bottom of the first plate 20. At this time, the bottom of the first plate 20 (i.e., the area corresponding to the bottom of the joint plate 11) is not blocked by the connecting part 30, forming an open space. Concrete can flow directly into the bottom and sides of the joint plate 11 without bypassing the connecting part 30, resulting in higher filling efficiency, further enhancing the fixing force of the joint plate 11, and further reducing the difficulty of the joint plate installation tool 10 detaching from the joint plate 11.

[0044] In some embodiments, please refer to the following for details. Figure 3 The first plate 20 is provided with a first hollow portion 25, which penetrates the first plate 20 along the thickness direction.

[0045] The concrete flowing through the first perforation 25 forms contact points on the side of the jointing plate 11. These contact points increase the fixing force of the concrete on the surface of the jointing plate 11, further improving the pull-out and displacement resistance of the jointing plate 11. The solid plate has a large contact area with the concrete, and the concrete has a strong bond to the first plate 20. However, this bond can easily cause difficulties during lifting. The first perforation 25 allows for discontinuous contact between the first plate 20 and the concrete, significantly reducing the bond strength and making lifting easier. This reduces the risk of the jointing plate installation tool 10 tilting due to excessive local bonding, and facilitates the smooth detachment of the jointing plate installation tool 10 from the jointing plate 11. The first perforation 25, while ensuring the structural strength of the plate, significantly reduces the overall weight of the jointing plate installation tool 10, making it easier to install, adjust, and lift, thus reducing the labor intensity of construction workers.

[0046] In some embodiments, please refer to the following for details. Figure 3 The first hollow portion 25 extends toward and penetrates the bottom surface of the first plate 20. That is, the first hollow portion 25 extends toward the first plate surface and penetrates the first bottom surface 24. When the concrete is poured, it will start filling from the bottom. The first hollow portion 25 penetrates the first bottom surface 24, forming a channel from the outside of the first plate 20 to the bottom of the joint plate 11. The concrete can quickly flow into the bottom and sides of the joint plate 11 through the first hollow portion 25 without having to go around the edge of the first plate 20, reducing the filling time and quickly forming the initial fixing force of the concrete on the joint plate 11, further reducing the difficulty of the joint plate installation tool 10 detaching from the joint plate 11.

[0047] In some embodiments, please refer to the following for details. Figure 4 The connecting portion 30 is provided with a second hollow portion 31, which penetrates the connecting portion 30 along its thickness direction. After the second hollow portion 31 penetrates the connecting portion 30, concrete can flow through the hollow portion into the connection area between the connecting portion 30 and the first plate 20, as well as the edge of the joint plate 11 near the connecting portion 30, ensuring that the concrete in this area is fully filled and free of voids. The second hollow portion 31 provides an additional flow channel for the concrete, allowing it to more evenly wrap around the side of the joint plate 11, further enhancing the fixing force of the joint plate 11 and further reducing the difficulty of the joint plate installation tool 10 detaching from the joint plate 11. At the same time, the second hollow portion 31 reduces the overall weight of the joint plate installation tool 10, making the joint plate installation tool 10 easier to install, adjust, and lift, thus reducing the labor intensity of construction workers.

[0048] Specifically, when the joint panel installation tool 10 is placed at the designated position where the joint panel 11 needs to be installed, the bottom of the first plate 20 can be a certain distance from the bottom surface of the concrete formwork, that is, the first plate 20 is suspended relative to the bottom surface of the concrete formwork. When the joint panel 11 is inserted into the gap between the two first plates 20 of the joint panel installation tool 10, a part of the bottom of the joint panel 11 will protrude from the bottom surface of the first plate 20. When the concrete is poured at this time, the concrete will directly wrap the part of the joint panel 11 that protrudes from the bottom surface of the first plate 20, which will have a fixing effect on the joint panel 11. When the joint panel installation tool 10 is pulled upward, the joint panel installation tool 10 can be smoothly detached from the joint panel 11.

[0049] For details, please refer to [link / reference]. Figure 1 The lifting part 40 can be set on the first main plane 21 of the corresponding first plate 20 away from the opposite first plate 20. The connection method can be welding or other methods, which are not specifically limited here. The lifting part 40 extends beyond the outer edge of the first plate 20, which can facilitate the placement of the lifting part 40 on the frame of the concrete formwork. This allows the frame of the concrete formwork to support the joint plate installation tool 10. After multiple joint plate installation tools 10 are placed at multiple positions where joint plates 11 need to be installed, concrete can be poured simultaneously, improving construction efficiency.

[0050] In some embodiments, please refer to the following for details. Figure 5 The distance between the corresponding top ends of the two first plates 20 is greater than the distance between the corresponding bottom ends of the two first plates 20. It can be understood that the distance between the two first plates 20 exhibits a structure with a wider top spacing and a narrower bottom spacing. The distance between the corresponding top ends of the two first plates 20 is the first distance D1, and the distance between the corresponding bottom ends of the two first plates 20 is the second distance D2. The wider top spacing and narrower bottom spacing create a wedge-like shape. When the joint plate installation tool 10 is pulled upwards, the wedge shape facilitates its removal from the concrete. In addition, the wide top spacing allows for a larger gap between the joint panel installation tool 10 and the top of the joint panel 11 when lifting, resulting in less friction between them and reducing the risk of the joint panel 11 being lifted together. The bottom spacing can be slightly larger than the thickness of the joint panel 11 to prevent the joint panel 11 from being lifted upwards together. At the same time, as the first panel 20 is lifted, the bottom of the joint panel 11 will be encased in concrete, which provides a certain degree of fixation for the joint panel 11. When the joint panel installation tool 10 is lifted upwards, it can easily detach from the joint panel 11.

[0051] Specifically, the difference between the first distance D1 and the second distance D2 should not be too large to avoid the joint plate 11 from shaking severely in the first slit 26, which would affect the vertical standing of the joint plate 11. The specific difference can be set according to the thickness and height of the joint plate. For example, the difference between the first distance D1 and the second distance D2 can be within 20% of the thickness of the joint plate, specifically 5%, 10%, 15%, 20%, etc., without specific limitation here.

[0052] In some embodiments, please refer to the following for details. Figure 6 The lifting part 40 has an anti-slip pattern 41 on the surface near the bottom edge of the first plate 20. The lifting part 40 is the core force application point for the lifting operation of the joint panel installation tool 10. The anti-slip pattern 41, such as stripes, raised dots, grids, etc., can directly increase the friction. During construction, whether it is manually lifted by hand or connected to the lifting part 40 with tools such as hooks and ropes, the anti-slip pattern 41 can increase the friction coefficient of the contact surface, prevent the hand or tool from slipping off the lifting part 40 when applying force, ensure that the pulling force can be stably transmitted, ensure the continuous lifting action, avoid sudden slippage causing a sudden change in the force on the tool, and reduce the risk of the joint panel 11 being displaced by the joint panel installation tool 10.

[0053] In some embodiments, please refer to the following for details. Figure 7 The lifting part 40 has a gripping groove 42 on the surface of the side near the bottom edge of the first plate 20. When manually lifting, fingers or palms can naturally embed into the gripping groove 42, preventing the hand from sliding on the surface of the lifting part 40. Compared with a smooth surface, the gripping groove 42 can fix the hand position through physical limitation, ensuring that the pulling force direction is always in the vertical direction, avoiding sudden changes in the force on the tool due to sudden slippage, and reducing the risk that the joint plate 11 will be displaced by the joint plate installation tool 10.

[0054] In some embodiments, please refer to the following for details. Figure 8 The joint panel installation tool 10 also includes a level 50 corresponding to the lifting part 40 to assist the joint panel installation tool 10 in maintaining a vertical upward lift. The joint panel 11 requires verticality and accurate positioning. The level 50, such as a bubble level 50, is installed on the lifting part 40 and synchronized with the joint panel installation tool 10. When the lifting direction of the joint panel installation tool 10 deviates from the vertical direction, the bubble in the level 50 will shift to one side, providing a visual deviation reference for the construction personnel. The construction personnel can adjust the lifting force and angle in real time according to the bubble position to ensure that the joint panel installation tool 10 always moves vertically upward, avoiding scraping the joint panel 11 or causing it to shift due to the joint panel installation tool 10 being tilted.

[0055] In some embodiments, please refer to the following for details. Figure 8The level 50 is located on the surface of the lifting part 40 on the side away from the bottom edge of the first plate 20. The lifting part 40 is the main observation area for construction workers. By placing the level 50 on its upper surface, the bubble position can be read without having to bend down or turn to the side, avoiding obstruction by concrete or hands. During the installation of the joint panel 11, the construction worker can scan the level 50 at any time during the lifting process to promptly determine if the tool is tilted, quickly adjust the lifting force and angle, ensure that the correction action is continuous and efficient, and ensure that the joint panel installation tool 10 always moves vertically upward, avoiding scraping the joint panel 11 or causing it to shift due to the joint panel installation tool 10 being tilted.

[0056] Specifically, the level 50 can be set at one or both ends of the lifting part 40, and can be adjusted according to actual needs, without being specifically limited here.

[0057] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
