Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a hollow block handling and installation tool. Background Technology

[0002] In the field of masonry structure construction in civil engineering, many types of blocks are used, especially hollow blocks. Hollow blocks not only improve load-bearing performance but also provide insulation, noise reduction, and material savings. During the installation of precast blocks, they need to be manually transported to the installation location, and cement mortar is applied to their underside and around them for bonding. Currently, there are two main methods for transporting and laying hollow blocks: one is for workers to manually transport the blocks to the installation location and repeatedly tap them with a hammer until the block's edges align with a horizontal guideline. The other method is for workers to use block clamps to hold the blocks in place and then tap them with a hammer to position them, ensuring the block's edges align with the horizontal guideline. However, manual labor is prone to slipping and hand injuries, while clamps can concentrate force, potentially crushing parts of the block. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems and provide a hollow block handling and installation tool. The lower support plate of the main frame is inserted into the hollow cavity of the hollow block, and the upper handle can be lifted together with the hollow block by relying on the support and limiting of the lower support plate. This will not cause the problem of the block falling off when grabbed by hand, nor will it cause the hollow block to be crushed by the clamp.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model discloses a hollow block handling and installation tool. The hollow block has hollow cavities arranged in a single row on its side wall. The tool includes a main frame, which includes an upper pressure plate and a lower support plate that are parallel to each other. The upper pressure plate is positioned above the top wall of the hollow block, and the lower support plate is inserted into the hollow cavity. There is a preset distance between the top wall of the hollow cavity into which the lower support plate is inserted and the top wall of the hollow block. There is an movable gap between the upper pressure plate and the lower support plate, and the movable gap is greater than the preset distance. A handle is provided on the surface of the upper pressure plate facing away from the lower support plate.

[0005] Preferably, a level measuring device is provided on the surface of the upper pressure plate facing away from the lower support plate.

[0006] Preferably, the level measuring device is a bubble level or a tilt sensor.

[0007] Preferably, the upper pressure plate is a rectangular plate, and the horizontal measuring device is located at the opposite corner of the rectangular plate.

[0008] Preferably, the handle is located on the central axis of the rectangular plate, parallel to the long side.

[0009] Preferably, the handle has a non-slip surface.

[0010] Preferably, the main frame further includes an L-shaped connecting plate, which includes a horizontal plate segment and a vertical plate segment that are perpendicular to each other. The end of the horizontal plate segment is fixedly connected to the end of the upper pressure plate, and the horizontal plate segment is parallel to the upper pressure plate. The end of the vertical plate segment is fixedly connected to the end of the lower support plate, and the vertical plate segment is perpendicular to the lower support plate.

[0011] Preferably, the connection between the horizontal plate segment and the vertical plate segment is a rounded corner.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments analyzed and obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this utility model is to provide a hollow block handling and installation tool to solve the problems existing in the prior art. After the lower support plate of the main frame is inserted into the hollow cavity of the hollow block, the upper pressure plate is lifted by the handle. With the support and limiting of the lower support plate, the main frame and the hollow block can be lifted together. This avoids the problem of the block falling off when grabbed by hand, and also avoids the problem of the clamp crushing the hollow block. Moreover, after being transported to the designated position, the upper pressure plate is used to press down on the hollow block to complete the construction and installation of the hollow block, without the need to use a hammer to knock the hollow block.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 2 As shown, this embodiment provides a hollow block handling and installation tool. The hollow block 6 has hollow cavities 7 on its sidewalls, arranged in a single row. Each row includes at least one hollow cavity 7. When there are multiple hollow cavities 7, the direction of the single row is parallel to the thickness direction of the hollow block 6, i.e., multiple hollow cavities 7 are arranged sequentially from the top wall to the bottom wall of the hollow block 6. The hollow block handling and installation tool includes a main frame, which includes a parallel upper pressure plate 1 and a lower support plate 2. The upper pressure plate 1 is positioned above the top wall of the hollow block 6, and the lower support plate 2 is inserted into the hollow cavity 7 of the hollow block 6. A preset distance H exists between the top wall of the hollow cavity 7 into which the lower support plate 2 is inserted and the top wall of the hollow block 6. Figure 1The H shown in the diagram illustrates the insertion of the lower support plate 2 into the hollow cavity 7 located at the top. When inserted into the hollow cavity 7 located at the bottom, H refers to the distance between the top wall of the bottom hollow cavity 7 and the top wall of the hollow block 6. When there are two hollow cavities 7, the lower support plate 2 can be inserted into either the top or bottom hollow cavity 7 of the hollow block 6. When there are more than two hollow cavities 7, the lower support plate 2 can be inserted into any one of them, but it is recommended to prioritize inserting into the hollow cavity 7 located in the middle or near the middle to ensure more reasonable force distribution and avoid force concentration at the top. There is a movable gap L between the upper pressure plate 1 and the lower support plate 2. The movable gap L is greater than the preset distance H. On the one hand, this ensures that the upper pressure plate 1 will not touch the hollow block 6 when the lower support plate 2 is inserted into the hollow cavity 7. On the other hand, it allows the upper pressure plate 1 to move up and down a certain distance after the lower support plate 2 is inserted into the hollow cavity 7, so that the upper pressure plate 1 can detach from or adhere to the top wall of the hollow block 6. The specific setting of this movable gap L requires not only to be greater than the preset distance H, but also to be comprehensively considered based on the overall thickness of the hollow block 6 and the number of hollow cavities 7. A handle 4 is provided on the surface of the upper pressure plate 1 facing away from the lower support plate 2. The handle 4 is located at the top of the tool during use, making it convenient for workers to carry.

[0024] Working principle:

[0025] First, insert the lower support plate 2 of the main frame into the hollow cavity 7 on the hollow block 6, and position the upper pressure plate 1 above the top wall of the hollow block 6. Then, lift the upper pressure plate 1 horizontally or tilted upwards using the handle 4 to lift the main frame connected to the hollow block 6 and transport it to the designated position. Next, move the upper pressure plate 1 downwards so that it fits tightly against the top wall of the hollow block 6, and then press the hollow block 6 downwards. After the top wall of the hollow block 6 is horizontal, pull the main frame outwards using the handle 4 to remove the lower support plate 2 from the hollow cavity 7, thus completing the transportation and construction of a single hollow block 6.

[0026] In one embodiment, the lengths of the upper pressure plate 1 and the lower support plate 2 (the dimension of the lower support plate 2 in the insertion direction) must be greater than half the length of the hollow block 6, so as to exceed the center of gravity of the hollow block 6. This prevents the weight of the non-inserted area of ​​the hollow block 6 from exceeding the weight of the inserted area during lifting, thus avoiding imbalance and causing the hollow block 6 to fall. Furthermore, during lifting, the non-inserted area of ​​the hollow block 6 can be positioned slightly upwards to further prevent weight imbalance.

[0027] In one embodiment, a level measuring device 5 is provided on the surface of the upper pressure plate 1 facing the lower support plate 2. After the upper pressure plate 1 is attached to the top wall of the hollow block 6, the level measuring device 5 can be used to determine whether the upper pressure plate 1 is level, and thus whether the hollow block 6 is level. The pressing process is then adjusted according to the result displayed by the level measuring device 5 until the level measuring device 5 shows level, thus eliminating the need for workers to pre-set a leveling line for leveling, and significantly improving the leveling accuracy. Each time the level is measured, the handle 4 must be released to avoid inaccurate test results caused by hand tremors. Since the width of the lower support plate 2 and the upper pressure plate 1 is usually smaller than the width of the hollow block 6, the position of the lower support plate 2 and the upper pressure plate 1 on the width of the hollow block 6 can be adjusted if necessary to achieve overall leveling of the hollow block 6. When one side of the hollow block 6 is level, the main frame can be pulled out, and then the lower support plate 2 of the main frame can be inserted into the other side of the hollow cavity 7 to adjust the other side of the hollow block 6.

[0028] In one embodiment, the level measuring device 5 is a bubble level or a tilt sensor. Tilt sensor measurements are quantifiable and more accurate. A bubble level, on the other hand, is less expensive and can be manufactured as needed.

[0029] In one embodiment, the upper pressure plate 1 is a rectangular plate, and the level measuring device 5 (spiral bubble or tilt sensor) is located at opposite corners of the rectangular plate (upper pressure plate 1) to facilitate observation of the level from different directions. Specifically, the level measuring device 5 can be provided at one pair of opposite corners of the upper pressure plate 1, or it can be provided at both opposite corners.

[0030] In one embodiment, the lower support plate 2 is also a rectangular plate.

[0031] In one embodiment, the handle 4 is located on the central axis parallel to the long side of the rectangular plate, which is more conducive to balancing the weight of the main frame in the width direction of the upper pressure plate 1, that is, making the weight of the main frame as consistent as possible on both sides of the handle 4. At the same time, the handle 4 is located on the central axis parallel to the long side of the rectangular plate. When the horizontal measuring device 5 (bubble level or tilt sensor) is located at the diagonal of the rectangular plate (upper pressure plate 1), that is, on the opposite side of the handle 4, it is also convenient for workers to observe the horizontal measuring device 5 from different directions, which can meet different construction habits.

[0032] In one embodiment, the handle 4 has a non-slip surface to increase friction with the hand, thereby preventing the hollow block 6 from slipping out of the hand and causing it to break and injure the worker.

[0033] In one embodiment, the handle 4 is provided with a rubber layer, which increases the friction with the hand and improves the comfort of holding.

[0034] In one embodiment, the handle 4 has a circular cross-section and the overall diameter of the handle 4 is the same, which helps to improve grip comfort.

[0035] In one embodiment, the handle 4 has a circular cross-section. The diameter of the middle part (corresponding to the middle part of the palm) of the handle 4 is larger than the diameter of the two ends (corresponding to the two ends of the palm). That is, the handle 4 is similar to a spindle shape, which is beneficial to the stability of the hand grip.

[0036] In one embodiment, the main frame also includes an L-shaped connecting plate 3, which includes a horizontal plate segment and a vertical plate segment that are perpendicular to each other. The end of the horizontal plate segment is fixedly connected to the end of the upper pressure plate 1, and the horizontal plate segment and the upper pressure plate 1 are parallel to each other. The end of the vertical plate segment is fixedly connected to the end of the lower support plate 2, and the vertical plate segment and the lower support plate 2 are perpendicular to each other.

[0037] In one embodiment, the connection between the horizontal and vertical plate segments is rounded, which can reduce stress concentration and reduce the risk of breakage and deformation at the connection between the horizontal and vertical plate segments.

[0038] In one embodiment, the thickness of the upper pressure plate 1 and the thickness of the lower support plate 2 are both greater than the thickness of the L-shaped connecting plate 3.

[0039] In one embodiment, the L-shaped connecting plate 3, the upper pressure plate 1, and the lower support plate 2 are all made of metal plates, such as steel plates. The L-shaped connecting plate 3, the upper pressure plate 1, and the lower support plate 2 are fixedly connected by welding, but other fixing methods, such as bolt connection, can also be used. Of course, the L-shaped connecting plate 3, the upper pressure plate 1, and the lower support plate 2 can also be made of other materials as needed.

[0040] In one implementation, after construction is completed, if the hollow block handling and installation tools are contaminated with cement mortar, they must be cleaned before use in other construction projects.

[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
