Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a quick assembly and disassembly connection structure for wooden formwork. Background Technology

[0002] In the construction industry, wooden formwork is widely used in concrete pouring projects due to its advantages such as low cost and ease of processing. During actual construction, wooden formwork typically needs to be assembled and disassembled according to project requirements to meet different shapes and sizes.

[0003] Currently, most common wooden formwork connection structures use traditional methods such as bolts and nails for fixing. This method has many drawbacks. For example, bolted connections require repeated tightening of bolts, which is cumbersome, time-consuming, and significantly impacts construction efficiency. Nail connections are difficult to disassemble, easily damage the formwork, and repeated use of nails reduces the connection's strength. Furthermore, these traditional connection methods require significant manpower and time during formwork assembly and disassembly, failing to meet the demands of efficient modern construction projects. Therefore, there is an urgent need to design a wooden formwork connection structure that enables rapid assembly and disassembly, is easy to operate, and provides a stable connection to improve construction efficiency and reduce costs. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a quick assembly and disassembly connection structure for wooden templates, which has the advantage of being able to easily assemble and disassemble wooden templates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly connection structure for wooden templates, comprising two template bodies:

[0006] Connecting blocks are fixedly installed on both sides of the two template bodies. Adjacent connecting blocks on the two template bodies fit together. Vertical grooves and short grooves are opened inside the connecting blocks. A rod is movably sleeved inside the short groove. A vertical rod is movably sleeved inside the rod. The outer surface of the vertical rod is movably sleeved with the inside of the vertical groove. A fixing plate is fixedly sleeved at the top of the vertical rod.

[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 obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a quick-assembly and disassembly connection structure for wooden templates, including two template bodies 1:

[0022] Connecting blocks 2 are fixedly installed on both the left and right sides of the two template bodies 1. The adjacent connecting blocks 2 on the two template bodies 1 fit together. The connecting blocks 2 have vertical grooves 3 and short grooves 4 inside. The short grooves 4 are movably fitted with insert rods 5. The insert rods 5 are movably fitted with vertical rods 6 inside. The outer surface of the vertical rods 6 is movably fitted with the inside of the vertical grooves 3. The top of the vertical rods 6 is fixedly fitted with a fixing plate 7. The bottom of the fixing plate 7 fits with the top of the connecting blocks 2.

[0023] The template body 1 is the main structure of the wooden template, used to form the molding surface for concrete pouring. The connecting block 2 is fixed on both sides of the template body 1, serving as the basic carrier for connecting the templates. The vertical groove 3 and short groove 4 inside the connecting block 2 provide insertion channels for the vertical rod 6 and the insert rod 5, respectively. When two template bodies 1 need to be connected, the adjacent connecting blocks 2 are fitted together. At this time, the insert rod 5 is inserted into the short groove 4 and the vertical rod 6 is inserted into the vertical groove 3. The two are fitted together by the outer surface of the vertical rod 6 and the inner surface of the insert rod 5, which restricts the relative displacement of the connecting block 2, thus achieving the initial positioning between the templates.

[0024] Among them, the internal thread of the fixing plate 7 is fitted with a bolt 8, and the outer surface of the bolt 8 is fitted with the internal thread of the top of the connecting block 2.

[0025] Bolt 8 passes through the fixing plate 7 and connects to the threaded hole at the top of the connecting block 2. Its core function is to firmly fix the fixing plate 7 to the connecting block 2, thereby forming an axial constraint on the vertical rod 6. When bolt 8 is tightened, the fixing plate 7 presses against the top of the connecting block 2, restricting the vertical rod 6 from moving upward out of the vertical groove 3, ensuring that the sleeve structure between the insert rod 5 and the vertical rod 6 is always locked, and preventing the formwork body 1 from loosening due to vibration and other factors during the pouring process. At the same time, the threaded connection of bolt 8 makes it easy for construction personnel to install and remove the fixing plate 7 by simple rotation, taking into account both connection stability and ease of operation.

[0026] Among them, a fixing block 9 is fixedly installed on the outer surface of the template body 1, an insert block 10 is inserted into the inside of the fixing block 9, a connecting rod 11 is fixedly installed on the front of the insert block 10, and a movable block 12 is movably sleeved on the outer surface of the connecting rod 11.

[0027] The fixing block 9 is fixed to the outer surface of the template body 1 and serves as an auxiliary connection structure to provide an insertion interface for the insert block 10. The insert block 10 is fixedly connected to the movable block 12 through the connecting rod 11. When the operator holds the movable block 12 and pushes the insert block 10 into the fixing block 9, the end of the insert block 10 will be stuck inside the fixing block 9, forming a mechanical block against the lateral relative movement of the two template bodies 1, thus achieving the initial positioning of the template.

[0028] A spring 13 is fixedly installed on the back of the movable block 12, and the rear end of the spring 13 is fixedly connected to the front of the insert block 10.

[0029] The spring 13 is connected to the movable block 12 and the insert block 10 at its two ends respectively. Its core function is to provide the movable block 12 with a reset elastic force: when the operator pulls the movable block 12 backward, the spring 13 is compressed and stores elastic potential energy; after the movable block 12 is released, the spring 13 releases potential energy to push the movable block 12 forward to reset.

[0030] Among them, the inner sides of the movable block 12 are fixedly fitted with round shafts 14, and the outer surface of the round shafts 14 is movably fitted with buckles 15.

[0031] The circular shaft 14 is fixed inside both sides of the movable block 12, serving as the rotation fulcrum of the buckle 15, allowing the buckle 15 to rotate around the circular shaft 14. When the movable block 12 slides backward, the buckle 15 moves backward synchronously with the circular shaft 14.

[0032] The rear end of the buckle 15 is fastened with a locking block 16, which is fixedly connected to the outer surface of the fixing block 9.

[0033] The locking block 16 is fixed to the outer surface of the fixing block 9. Its shape matches the fastening part of the buckle 15, and the two form a fastening structure: when the buckle 15 rotates around the round shaft 14, its hook will be engaged in the groove or flange of the locking block 16 to form a mechanical lock; when the elastic force of the spring 13 pushes the movable block 12 forward, the hook of the buckle 15 is tightly fitted with the locking block 16, further tightening the insertion state of the insert block 10 and the fixing block 9.

[0034] Working principle and usage process of this utility model:

[0035] When using the quick-assembly and disassembly connection structure for wooden templates of this utility model, the operator first aligns and fits the adjacent connecting blocks 2 on the two template bodies 1, so that the vertical groove 3 of the connecting block 2 corresponds to the short groove 4. Then, the operator holds the movable block 12 and inserts the insert block 10 into the fixed block 9 on the outer surface of the template body 1. At this time, the insert block 10 forms an initial block against the relative movement of the two template bodies 1 through the fixed block 9, realizing the initial positioning of the template. Next, the operator pushes the movable block 12 backward. The movable block 12 slides along the outer surface of the connecting rod 11 and compresses the spring 13 at the rear end. At this time, the movable block 12 drives the two buckles 15 on both sides to move backward through the round shaft 14. When the buckles 15 move to the position corresponding to the buckle 16 on the outer surface of the fixed block 9, the operator reverses the buckle 15 to make it rotate around the round shaft 14. After releasing the movable block 12, the elastic force of the spring 13 pushes the movable block 12 forward to reset, causing the buckle 15 to engage with the outer surface of the buckle 16, so that the insert block 10 is firmly inserted into the fixed block 9, completing the initial fixation between the templates.

[0036] After initial fixation, insert rod 5 into the short groove 4 of connecting block 2, then hold fixing plate 7 and insert vertical rod 6 into vertical groove 3 of connecting block 2, so that the outer surface of vertical rod 6 is movably sleeved with the inside of insert rod 5. At this time, vertical rod 6 locks the movement of insert rod 5. At the same time, insert rod 5 and vertical rod 6 cooperate to restrict the relative displacement of connecting block 2. Finally, fixation plate 7 and top of connecting block 2 are threadedly connected by bolt 8 to achieve final fixation between templates. When disassembly is required, the operation is reversed: first unscrew bolt 8 to remove fixing plate 7, pull out vertical rod 6 and insert rod 5 to release the lock on connecting block 2, then push movable block 12 backward to compress spring 13, rotate buckle 15 to disengage it from buckle 16, release movable block 12 and spring 13 to return to its original position, then pull out insert block 10, and finally separate the two template bodies 1. Throughout the process, the elastic fastening structure consisting of movable block 12, spring 13, buckle 15 and buckle block 16 enables the rapid initial fixing and positioning of the template. The cooperation of insert rod 5, vertical rod 6, fixing plate 7 and bolt 8 forms a rigid connection. The dual fixing mechanism not only ensures the efficiency of disassembly and assembly, but also enhances the stability of the template connection, meeting the needs of rapid assembly and firm connection of templates during construction.
