Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a reusable narrow strip of loosely assembled wooden formwork. Background Technology

[0002] In the construction industry, wooden formwork is widely used due to its low cost and ease of processing. However, traditional wooden formwork has many shortcomings. Traditional wooden formwork is mostly made of whole boards or spliced ​​wide boards. When constructing irregular structures, cutting generates a large amount of unusable scrap material, resulting in serious resource waste. Moreover, it is prone to deformation and damage after disassembly, with low reuse rate. After multiple uses, the precision decreases, leading to a high scrap rate. Therefore, there is an urgent need to develop a new type of wooden formwork technology that is reusable, structurally flexible, and environmentally friendly.

[0003] Meanwhile, the patent specification with application number CN217711674U discloses a hole-free reinforcement structure for loose-piece timber formwork. "This utility model can easily connect and reinforce the first and second loose-piece timber formwork bodies by setting up connecting and reinforcing components. Then, the left side of the first and second loose-piece timber formwork bodies is reinforced and supported by connecting support components. This solves the problem that existing loose-piece timber formwork needs to be fixed during use to ensure the stability of the loose-piece timber formwork. However, when fixing the loose-piece timber formwork, not only are a large number of threaded holes required, but also a large number of reinforcement structures need to be installed and fixed one by one on the surface of the loose-piece timber formwork. After use and disassembly, the interior of the loose-piece timber formwork is prone to cracking and damage, thereby reducing the effectiveness of the loose-piece timber formwork. This invention achieves the effect of easy reinforcement."

[0004] Existing wooden formwork splicing devices rely heavily on bolts, nails, and other fasteners in traditional splicing methods. The installation and disassembly process is cumbersome and time-consuming, requiring various tools and demanding high skill levels from operators. Furthermore, uneven stress or repeated disassembly and assembly can easily damage the formwork structure, reducing the reusability of the formwork and increasing construction costs.

[0005] Therefore, a reusable narrow strip of loosely assembled wooden formwork is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a reusable narrow strip modular wooden formwork, which features the advantage of allowing for quick engagement and disengagement of inserts and slots simply by pressing a pressing rod. This significantly improves the efficiency of formwork assembly and disassembly, shortens the construction cycle, avoids damage to the formwork caused by traditional connection methods, greatly increases the reusability of the formwork, and reduces construction costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reusable narrow strip modular wooden template, comprising two wooden template bodies, both of which share two quick-release components. Each quick-release component includes a connecting frame, with a connecting plate movably inserted into the top of the connecting frame. Both wooden template bodies share a receiving groove for use with the connecting frame. The connecting plate, the connecting frame, and both wooden template bodies are provided with circular grooves. The inner surfaces of the three circular grooves located on the same vertical line are provided with insert rods.

[0008] Preferably, the insertion rod includes a pressing rod, the outer surface of which is slidably connected to the inner surface of the insertion rod, a tension spring is wound around the outer surface of the pressing rod located inside the insertion rod, a circular plate is fixedly connected to the bottom end of the pressing rod, a lifting block is fixedly connected to the bottom end of the circular plate, two insertion blocks are slidably connected to the outer surface of the lifting block, and two slots are opened in the circular groove on the connecting frame, both insertion blocks penetrate the insertion rod and extend into the slots.

[0009] Preferably, the lifting block is conical, and two slides are provided on the outer surface of the lifting block. Two guide bars are fixedly connected to the inner walls on both sides of the two slides, and guide grooves are provided at both ends of the two inserts to cooperate with the two guide bars.

[0010] Preferably, two sliders are fixedly connected to the outer surface of the circular plate, and the inner surface of the insertion rod is provided with a groove for use with the two sliders.

[0011] Preferably, both the connecting frame and the connecting plate are made of stainless steel.

[0012] Preferably, the top end of the tension spring is fixedly connected to the upper inner wall of the insert rod, and the bottom end of the tension spring is fixedly connected to the circular plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a quick-release component, this utility model allows the insertion block and slot to be quickly engaged and disengaged simply by pressing the pressing rod, under the synergistic action of the insertion rod, pressing rod, tension spring, lifting block and insertion block. This significantly improves the efficiency of template splicing and disassembly and shortens the construction cycle.

[0015] 2. This utility model, through the cooperation of a conical lifting block with guide strips and guide grooves, allows the insert block to be firmly inserted into the slot under the elastic action of the tension spring, forming a reliable connection. This effectively improves the overall stability and load-bearing capacity of the template, while avoiding damage to the template caused by traditional connection methods, greatly improving the template's reusability and reducing construction costs.

[0027] 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.

[0028] like Figures 1 to 6 As shown, this utility model provides a reusable narrow strip loose-joint wooden template, including a wooden template body 1, two wooden template bodies 1 are provided, and the two wooden template bodies 1 are provided with two quick-release components 2.

[0029] The quick-release assembly 2 includes a connecting frame 21, with a connecting plate 22 movably inserted at the top of the connecting frame 21. The two wooden template bodies 1 are provided with a receiving groove 3 for use with the connecting frame 21. The connecting plate 22, the connecting frame 21, and the two wooden template bodies 1 are all provided with circular grooves 4. The inner surfaces of the three circular grooves 4 located on the same vertical line are provided with insert rods 5. By setting the quick-release assembly 2, the quick connection and disassembly between the wooden template bodies 1 are realized, which improves construction efficiency, facilitates template reuse, and reduces costs.

[0030] Specifically, the insertion rod 5 includes a pressing rod 51, the outer surface of the pressing rod 51 is slidably connected to the inner surface of the insertion rod 5, a tension spring 52 is wound around the outer surface of the pressing rod 51 located inside the insertion rod 5, a circular plate 54 is fixedly connected to the bottom end of the pressing rod 51, a lifting block 55 is fixedly connected to the bottom end of the circular plate 54, two insertion blocks 554 are slidably connected to the outer surface of the lifting block 55, two slots 211 are opened in the circular groove 4 on the connecting frame 21, and both insertion blocks 554 penetrate the insertion rod 5 and extend into the slots 211. The special structural design of the insertion rod 5 makes the template connection stable, and the insertion and removal of the insertion blocks 554 can be achieved by pressing, making the operation simple and convenient.

[0031] like Figures 1 to 6 As shown, the lifting block 55 is conical, and two slides 552 are provided on the outer surface of the lifting block 55. Two guide bars 551 are fixedly connected to the inner walls on both sides of the two slides 552. Guide grooves 553 are provided at both ends of the two insert blocks 554 to cooperate with the two guide bars 551. The conical lifting block 55, in conjunction with the guide structure, ensures that the insert blocks 554 slide accurately during the lifting process, prevents the insert blocks 554 from deviating, and ensures the reliability of the connection.

[0032] Furthermore, two sliders 555 are fixedly connected to the outer surface of the circular plate 54, and the inner surface of the insert rod 5 is provided with a groove 53 for use with the two sliders 555.
