Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a wooden board clamp for building construction. Background Technology

[0002] In construction, wooden planks are frequently used to construct casting molds. Traditionally, these planks are fixed by directly nailing steel nails into them. However, this method often results in weak connections at the plank joints or corners. Especially during subsequent concrete pouring, the pressure of the concrete can cause the plank joints to loosen, leading to formwork displacement (i.e., the pouring concrete pushing the planks apart from the casting mold). This not only affects the quality of the pour but can also cause construction accidents. Therefore, a more stable and reliable wooden plank clamp is needed to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a wooden board clamp for building construction, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wooden board clamp for building construction, comprising multiple connecting blocks, each connecting block having two threaded holes evenly distributed through its outer wall, the threaded holes being staggered in a corresponding cross shape, each threaded hole having a tightening screw threaded to both ends, each tightening screw having a drive adjustment plate at one end away from the connecting block, each drive adjustment plate having a fixing block at one end near the connecting block, and each fixing block having multiple steel nails evenly distributed at one end away from the tightening screw.

[0005] As a further embodiment of this utility model, all of the steel nails are fixedly connected to the fixing block through the block.

[0006] As a further improvement of this utility model: the two fixed blocks each have a slot on the side wall near one end of the drive adjustment plate, and the two drive adjustment plates have a block fixedly connected to the side wall where the slot position matches the slot.

[0007] As a further embodiment of this utility model: the outer diameter of both of the card blocks matches the inner diameter of the card slot, and the two card blocks are engaged and connected with the card slot.

[0008] As a further embodiment of this utility model: multiple clamping screws are threadedly connected to a drive adjustment plate that matches the position, and one end of each clamping screw that passes through the drive adjustment plate is threadedly connected to an adjustment nut.

[0009] As a further improvement of this utility model: the length distance between the two fixed blocks and their ends is less than the length distance between the adjusting plate and its ends.

[0010] Compared with existing technologies, the advantages of this invention are as follows: By using a tightening screw and a driving adjusting plate, the wooden boards can be tightly clamped, effectively preventing loosening and formwork displacement during pouring. The clamp's design makes it suitable for connecting wooden boards of different sizes and shapes, providing stable fixation for both planar and corner connections. The clamping force can be easily adjusted by rotating the adjusting nut, making installation and disassembly simpler and faster. Using this clamp significantly reduces rework and repair time caused by weak connections, thereby improving overall construction efficiency. Attached Figure Description

[0020] Example 1: Reinforcement of Flat Wood Board Connections

[0021] Application scenario: On construction sites, multiple wooden planks need to be connected in parallel to form a large flat template for concrete pouring.

[0022] How to use:

[0023] Place multiple connecting blocks 1 on the wooden board at predetermined intervals, ensuring that the threaded holes 11 on the connecting blocks correspond to the connection positions on the wooden board.

[0024] Use the clamping screw 2 to pass through the threaded hole 11 on the connecting block 1, and connect one end of the clamping screw 2 to the drive adjustment plate 3.

[0025] Install a fixing block 4 at the other end of the adjusting plate 3 to ensure that the steel nails 41 on the fixing block 4 can be firmly driven into the wooden board.

[0026] By rotating the adjusting nut 21, the clamping screw 2 drives the adjusting plate 3 and the fixing block 4 to move closer to the center of the wooden board, thereby clamping the wooden board and achieving a firm connection.

[0027] Example 2: Reinforcement of wooden board connections at corners

[0028] Application scenario: At the corners of building formwork, wooden boards need to be connected at a certain angle to ensure the integrity and stability of the formwork.

[0029] How to use:

[0030] Place connecting blocks 1 on the two wooden boards at the corner, and ensure that the threaded holes 11 on the connecting blocks correspond to the connection positions of the wooden boards.

[0031] Two clamping screws 2 are passed through the corresponding threaded holes 11 on the connecting block 1, and one end of the clamping screw 2 is connected to the drive adjustment plate 3.

[0032] Install a fixing block 4 at the other end of the adjusting plate 3 to ensure that the steel nails 41 on the fixing block 4 are firmly driven into the wooden board. Since the angle of the wooden board at the corner is different, the position of the fixing block 4 and the adjusting plate 3 can be adjusted to accommodate different angles.

[0033] By rotating the adjusting nut 21, the fastening screw 2 drives the adjusting plate 3 and the fixing block 4 to move closer to the center of the wooden board, thereby clamping the wooden board and achieving a firm connection. At the same time, the design of the locking block 31 and the locking groove 42 ensures a stable connection between the adjusting plate 3 and the fixing block 4.

[0034] Example 3: Reinforcement through multi-layer wooden board stacking and connection

[0035] Application scenario: In some buildings that require high load-bearing capacity, multiple layers of wooden planks need to be stacked together to form a more robust formwork.

[0036] How to use:

[0037] Place a connecting block 1 on each layer of wood, ensuring that the threaded holes 11 on the connecting block correspond to the connection positions of the wood. Also, ensure that the positions of the connecting blocks correspond between different layers.

[0038] Use a clamping screw 2 to pass through the threaded hole 11 on the connecting block 1 on each layer of wooden board, and connect the two ends of the clamping screw 2 to the driving adjustment plate 3 of the upper and lower layers respectively.

[0039] A fixing block 4 is installed on the outside of the adjusting plate 3, and steel nails 41 are used to firmly nail the fixing block 4 into the wooden board. This ensures that each layer of wooden board is clamped and firmly connected.

[0040] By rotating the adjusting nut 21, the clamping screw 2 drives the adjusting plate 3 and the fixing block 4 to move closer to the center of the wooden board, thereby clamping the multiple layers of wooden boards and achieving a firm connection. This connection method can significantly improve the load-bearing capacity and stability of the template.

[0041] In summary: Please refer to Figures 1-4 In this embodiment of the invention, a wooden board clamp for construction mainly includes multiple connecting blocks 1. Two threaded holes 11 are evenly and continuously formed on the outer wall of each connecting block 1, and these threaded holes 11 are staggered in a corresponding cross shape. This design allows the clamping bolts 2 to be inserted from different directions, increasing the flexibility and stability of the clamp.

[0042] Each threaded hole 11 has a clamping screw 2 threaded to both ends. Each clamping screw 2 has a drive adjustment plate 3 at the end furthest from the connecting block 1. Each drive adjustment plate 3 has a fixing block 4 at the end closest to the connecting block 1. Multiple steel nails 41 are evenly distributed at the end of each fixing block 4 furthest from the clamping screw 2.

[0043] Furthermore, each of the two fixing blocks 4 has a slot 42 on its side wall near one end of the drive adjustment plate 3, and each of the two drive adjustment plates 3 has a locking block 31 fixedly connected to its side wall where the slot 42 is matched. These locking blocks 31 match the slot 42, which can firmly connect the drive adjustment plate 3 and the fixing block 4 together.

[0044] In practical applications, an appropriate number of clamping screws 2 can be selected and connected to the threaded holes 11 on the connecting block 1 as needed. Then, the steel nails 41 on the fixing block 4 are driven into the wooden board to be connected. Next, the locking block 31 is engaged with the locking groove 42 to ensure a firm connection between the driving adjusting plate 3 and the fixing block 4.

[0045] The working principle of this utility model is as follows:

[0046] Connection and fixation:

[0047] The initial connection between the wooden board and the clamp is achieved by nailing the steel nail 41 on the fixing block 4 into the wooden board that needs to be connected.

[0048] The locking block 31 is engaged with the locking slot 42 to ensure a firm connection between the driving adjustment plate 3 and the fixing block 4, thereby further strengthening the connection between the wooden board and the clamp.

[0049] Adjustment and tightening:

[0050] By rotating the adjusting nut 21, the clamping screw 2 can be moved in the threaded hole 11, thereby causing the adjusting plate 3 to move accordingly.

[0051] Since the adjusting plate 3 and the fixed block 4 are connected by the locking block 31 and the locking groove 42, when the adjusting plate 3 moves, it will drive the fixed block 4 and the wooden board connected to it to move accordingly.

[0052] When two wooden boards need to be tightly connected, the adjusting nut 21 can be rotated continuously to make the two wooden boards gradually approach each other under the action of the clamping screw 2 and the driving adjusting plate 3 until the required tightness is achieved.

[0053] Stabilization and reinforcement:

[0054] Because the clamp uses a design with multiple connecting blocks 1 and clamping screws 2, it can ensure a stable connection and reinforcement of the wooden board in multiple directions.

[0055] Meanwhile, by adjusting the rotation of nut 21, the tightness of the clamp can be flexibly adjusted to meet the connection needs of wooden boards of different sizes and shapes.
