Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a quick-assembly and disassembly template for the main construction of buildings. Background Technology

[0002] Construction formwork is a temporary support structure, made according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate the construction progress, and reduce project costs.

[0003] Patent document CN219528380U discloses a quick-assembly and disassembly template for building construction, including a first template and a second template. The second template is located to the right of the first template, and both sides of the second template have linkage grooves. The rear part of the inner cavity of the linkage groove is rotatably connected to a rotating rod through a bearing. This utility model places the second template vertically on one side of the second template or arranges the second template and the first template in a row, and then inserts a meshing plate into the inside of the linkage groove. After the meshing plate is inserted into the linkage groove, it drives the second square rod to rotate through a gear. At this time, the bolt can be screwed into the first bolt groove or the second bolt groove to fix the second template and the first template. This structure can not only assemble the first template and the second template in different positions, but also achieve the effect of quick installation or disassembly of the first template and the second template.

[0004] However, the existing disassembly and assembly templates involve components such as gears and meshing plates that require precise matching, which not only results in higher maintenance costs but also makes the structure for achieving rapid disassembly and assembly somewhat complex. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a quick-assembly and disassembly template for the main construction of buildings, which has a simple structure and can be quickly assembled and disassembled.

[0006] A quick-assembly and disassembly formwork for building construction includes a first formwork and a second formwork. The side wall of the second formwork is integrally formed with a connecting block. The side wall of the first formwork has a first connecting groove adapted to the connecting block. The connecting block is inserted into the first connecting groove. The bottom wall of the first connecting groove is recessed to form a second connecting groove. A baffle slides in the two second connecting grooves and is attached to the second formwork. The upper end face of the first formwork is integrally formed with a locking block. The lower end face of the first formwork is recessed with a locking groove adapted to the locking block.

[0007] Furthermore, a fixing plate is fixedly connected to the side wall of the first template, and the baffle is connected to the fixing plate by bolts.

[0008] Furthermore, a washer is fitted onto the end of the bolt away from the screw head, and a nut is threaded onto it.

[0009] Furthermore, at least two grooves are provided on the sides of the two second templates that are far apart from each other, and a slider is integrally formed on the side of the baffle that is close to the second template, and the slider slides in the groove.

[0010] Furthermore, the cross-sectional shape of the groove is T-shaped.

[0011] Furthermore, two slides are provided.

[0012] Furthermore, both the baffle and the first template are fixedly connected to handles.

[0013] Furthermore, corner protectors are fixed to all four corners of the first template.

[0014] Furthermore, the corner protector block has a groove.

[0015] Furthermore, both the first template and the second template are steel templates.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, during demolding, the baffle is slid upwards and pulled out, and the mold is removed sequentially from top to bottom. The end of a pry bar is inserted into the gap between the connecting block and the first connecting groove, and the second template is forcefully removed from the first template. Then, the pry bar is used to pry open the gap between two vertically adjacent first templates to remove the upper first template. The removal of the templates is completed sequentially. The quick-assembly and disassembly template structure in this embodiment is simple, requiring only the connecting block, the first connecting groove, the second connecting groove, the baffle, the locking block, and the locking groove to complete quick assembly and disassembly. No highly precise fitting parts are required, resulting in low maintenance costs. Attached Figure Description

[0024] 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. Specific implementation examples:

[0026] like Figure 1-4As shown, a quick-assembly and disassembly formwork for building construction includes two first formworks 1 and two second formworks 2. The two first formworks 1 and the two second formworks 2 are arranged in parallel pairs. A connecting block 3 is integrally formed on the side wall of each second formwork 2. A first connecting groove 4 adapted to the connecting block 3 is opened on the side wall of each first formwork 1, allowing the connecting block 3 to be inserted into the first connecting groove 4. A second connecting groove 5 is formed by the recessed inner bottom wall of the first connecting groove 4. Baffles 6 slide within the two second connecting grooves 5 on the same side of each of the two first formworks 1. The two ends of the baffles 6 are connected by a first connecting groove 4. When the first template 2 is slidably installed into the second connecting groove 5 after being connected into the connecting groove 4, it fits snugly against the second template 2. The baffle 6 is used to prevent the second template 2 from detaching from the first template 1 and also to prevent the two first templates 1 from moving away from each other. The upper end face of the first template 1 is integrally formed with a locking block 7, and the lower end face of the first template 1 is recessed with a locking groove 8 that matches the locking block 7. The locking block 7 on the lower first template 1 can be locked into the locking groove 8 of the adjacent first template 1 on the upper side. When installing the templates from bottom to top, first place the two first templates 1 vertically, and then install them separately. Insert the connecting blocks 3 at both ends of the two second templates 2 into the first connecting grooves 4, and then slide the two ends of the baffle 6 into the second connecting grooves 5. This completes the installation of the template for this layer. When installing the adjacent upper template, first put the slot 8 of the first template 1 onto the slot 7 of the lower first template 1, and then repeat the previous operation to install the second template 2 and the baffle 6. Install them in this way to complete the pouring and formwork work for the columns (square columns) of the main building structure. When dismantling the formwork, slide the baffle 6 upwards and pull it out. Remove it from top to bottom in sequence by using a pry bar. The end of the rod is inserted into the gap between the connecting block 3 and the first connecting groove 4. The second template 2 is forcefully removed from the first template 1. Then, the gap between the two adjacent first templates 1 in the vertical direction is pried open with a pry bar to remove the upper first template 1. The template removal is completed in sequence. The quick-assembly and disassembly of the template in this embodiment has a simple structure for installation and disassembly. It only requires the cooperation of the connecting block 3, the first connecting groove 4, the second connecting groove 5, the baffle 6, the locking block 7 and the locking groove 8 to complete the quick assembly and disassembly. It does not require parts with high precision and has low maintenance costs.

[0027] like Figure 1-4 As shown, a fixing plate 9 is fixedly connected to the side wall of the first template 1. The baffle 6 and the fixing plate 9 are connected by bolts 10. The end of the bolt 10 away from the bolt head is fitted with a washer and threaded with a nut. After the baffle 6 is slid into the second connecting groove 5, the baffle 6 is connected to the fixing plate 9 by bolts 10, so that the baffle 6 is connected to the first template 1 and cannot move relative to it, making the template system more stable and safer. The baffle 6 can also support the second template 2 and relieve the pressure (thrust) of the concrete on the second template 2 during pouring. Furthermore, when removing the template, only the operation of removing the bolts 10 is added, which does not affect the quick disassembly of the template.

[0028] like Figure 1-4 As shown, at least two T-shaped grooves 11 are provided on the sides of the two second templates 2 that are far apart from each other. In this embodiment, two grooves 11 are provided. A slider 12 that slides in the groove 11 is integrally formed on the side of the baffle 6 near the second template 2. The cross-sectional shape of the slider 12 is the same as that of the groove 11. By setting the T-shaped slider 12 in conjunction with the groove 11, when the baffle 6 is slidably removed, the baffle 6 is pulled outward (or the second template 2 is pried), and the baffle 6 and the second template 2 can be removed at the same time, which improves efficiency.

[0029] like Figure 1-4 As shown, handles 13 are fixedly connected to both the baffle 6 and the first template 1. The inner top wall of the slide groove 11 is flush with the upper end face of the connecting block 3. Thus, when installing the second template 2, simply lift the baffle 6 so that the slider 12 fits against the inner top wall of the slide groove 11, push the second template 2 into the first connecting groove 4, and then lower the baffle 6 so that both ends of the baffle 6 slide into the second connecting groove 5 for quick installation.

[0030] like Figure 1-4 As shown, corner protectors 14 are fixedly connected to the four corners of the first template 1. The corner protectors 14 are provided with grooves 15. The corner protectors 14 and grooves 15 are provided to facilitate the installation of template fasteners as needed.

[0031] like Figure 1-4 As shown, both the first template 1 and the second template 2 are steel templates. Steel templates are relatively heavy (approximately 15-30 kg per template). During installation, a crane and hoisting ropes can be used, with the ropes tied to the handle 13 for the workers to install. In the second template 2, the distance between the inner wall of the groove 11 and the other side of the second template 2 is the same as the thickness of the first template 1, thus ensuring that the strength of the groove 11 of the second template 2 is the same as that of the first template 1. The corner protector 14 is made of wood to reduce costs. The corner protector 14 is glued to the first template 1 with strong adhesive. The baffle 6 is made of iron, and the connection between the baffle 6 and the bolt 10 is pre-threaded for mating with the bolt 10.

[0032] The working principle of a quick-assembly and disassembly template for building construction in this embodiment is as follows: During installation, the two first templates 1 are firstly placed vertically, and the baffle 6 is lifted with the help of a crane, so that the slider 12 fits against the inner top wall of the slide groove 11. The second template 2 is then pushed into the first connecting groove 4. After that, the baffle 6 is lowered, so that both ends of the baffle 6 slide into the second connecting groove 5. Then, the baffle 6 and the fixing plate 9 are connected by bolts 10 for quick installation. During disassembly, the bolts 10 are removed, and the baffle 6 is pulled upward with the help of a crane, so that the upper end of the slider 12 abuts against the inner top wall of the slide groove 11. The connecting block 3 on the baffle 6 and the second template 2 is pulled out of the first connecting groove 4. Then, the first template 1 is disassembled. This allows for quick assembly and disassembly. The structure is simple, requiring only the connection block 3, the first connecting groove 4, the second connecting groove 5, the baffle 6, the locking block 7, and the locking groove 8 to complete the quick assembly and disassembly. No precision-fitting parts are required, resulting in low maintenance costs.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
