Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and in particular to a building formwork connection structure that is easy to disassemble. Background Technology
[0002] In the construction industry, formwork serves as a crucial auxiliary tool for concrete pouring and shaping. The rationality of its connection structure directly impacts construction efficiency, concrete quality, and formwork reusability. Currently, common formwork connection structures on the market mainly suffer from the following problems: First, traditional formwork often uses an integral structure or is connected by complex snap-fit and welding methods. During the disassembly process, a large number of special tools are often required, and the disassembly steps are cumbersome. This not only consumes a lot of manpower and time, but also easily damages the formwork during the disassembly process, reducing the number of times the formwork can be reused and increasing construction costs.
[0003] Secondly, the existing formwork connection structure makes it difficult to guarantee the alignment accuracy between adjacent formwork units during assembly, which can easily lead to excessive gaps or misalignment of the formwork splices. This can result in grout leakage during concrete pouring, affecting the appearance quality and structural strength of the concrete components. Additional repair work is required afterward, further increasing the construction period and cost. Moreover, the lateral pressure on the formwork during concrete pouring may cause the formwork to deform or collapse, posing a significant construction safety hazard. Utility Model Content
[0004] This utility model addresses the aforementioned problems in the existing technology by providing a building formwork connection structure that is easy to disassemble.
[0005] The objective of this utility model is mainly achieved through the following solution: A building formwork connection structure that is easy to disassemble includes several detachable and fixedly connected formwork units. Each formwork unit has multiple fixing holes evenly provided along its side length on its four sides. Adjacent formwork units are connected by fixing bolts passing through the corresponding fixing holes. The formwork unit has multiple layers, and each layer is equipped with a horizontally arranged alignment square tube. The alignment square tube is installed on the side wall of the formwork unit by locking components.
[0006] Preferably, the template unit is a square plate, and a fixing plate is integrally provided on all four sides of its outer side, with the fixing holes opened on the fixing plate.
[0007] Preferably, the locking member is connected to the fixing holes of two adjacent template units; the locking member includes an L-shaped support plate and a pull-down locking plate, the rear end of the L-shaped support plate is connected to the fixing hole by a fixing bolt, and a receiving cavity for placing the alignment square tube is formed between the rear side of the pull-down locking plate, the rear upper surface of the L-shaped support plate and the front side of the template unit.
[0008] Preferably, the front end of the L-shaped support plate is equipped with a locking bolt, and the pull-down locking plate has an elongated hole that gradually descends from front to back. The locking bolt passes through the elongated hole, and as the pull-down locking plate gradually moves downward, the rear side of the pull-down locking plate will gradually squeeze the aligned square tube.
[0009] Preferably, the rear side of the pull-down locking plate is provided with a buffer pad.
[0010] In summary, compared with the prior art, the present invention has the following beneficial technical effects: (1) This utility model connects adjacent template units by fixing bolts, and uses locking parts composed of L-shaped support plates and pull-down locking plates to fix the alignment square tubes. When disassembling, it is only necessary to unscrew the fixing bolts and loosen the locking bolts. No complicated tools and cumbersome steps are required, which greatly shortens the time for template assembly and disassembly, reduces manpower input, and significantly improves construction efficiency. (2) Fixing holes are evenly opened on the fixing plate around the template unit in this utility model. Adjacent template units are precisely connected through fixing holes and fixing bolts, which effectively avoids the problem of excessive gaps or misalignment of template splicing. At the same time, the horizontally set alignment square tube can perform horizontal positioning of multi-layer template units, further ensuring the overall alignment accuracy of multi-layer templates, preventing grout leakage during concrete pouring, and improving the appearance quality and structural strength of concrete components. (3) In this utility model, the pull-down locking plate of the locking component cooperates with the locking bolt through the inclined elongated hole, which can realize the squeezing and locking of the alignment square tube, ensure that the alignment square tube is firmly connected to the template unit, enhance the overall stability and resistance to lateral pressure of the template, effectively prevent the template from deforming or collapsing during the concrete pouring process, and reduce construction safety hazards. (4) All components in this utility model are detachable. The template unit, the alignment square tube and the locking parts can be reused. There is no need to frequently replace new parts, which significantly reduces the construction cost. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.
[0014] like Figure 1-3 As shown, this utility model discloses a technical solution, a building formwork connection structure that is easy to disassemble, including several detachable and fixedly connected formwork units 1. Each of the four sides of the formwork unit 1 is provided with a plurality of fixing holes 2 evenly distributed along its side length. Adjacent formwork units 1 are connected by fixing bolts passing through the corresponding fixing holes 2. The formwork unit 1 has multiple layers, and each layer is equipped with a horizontally arranged alignment square tube 3. The alignment square tube 3 is installed on the side wall of the formwork unit 1 by locking parts 4.
[0015] Furthermore, to improve the stability of the connection between template units 1 and the ease of installation of the fixing holes 2, template unit 1 is a square plate, and a fixing plate 5 is integrally provided on all four sides of its outer surface, with the fixing holes 2 formed on the fixing plate 5. The integrally formed fixing plate 5 not only enhances the structural strength of the edge of template unit 1, but also makes the position of the fixing holes 2 more precise, avoiding the problem that adjacent template units 1 cannot be accurately connected due to the deviation in the position of the fixing holes 2.
[0016] Furthermore, to ensure the secure installation and convenient disassembly of the alignment square tube 3, while also guaranteeing its lateral support for the template unit 1, a locking component 4 is connected to the fixing holes 2 of two adjacent template units 1. The locking component 4 includes an L-shaped support plate 6 and a pull-down locking plate 7. The rear end of the L-shaped support plate 6 is connected to the fixing hole 2 via a fixing bolt. A receiving cavity 8 for placing the alignment square tube 3 is formed between the rear side of the pull-down locking plate 7, the rear upper surface of the L-shaped support plate 6, and the front side of the template unit 1. The receiving cavity 8 effectively positions the misaligned square tube 3, preventing displacement during use and ensuring the overall stability of multiple template units 1.
[0017] Furthermore, to enhance the locking effect of the alignment square tube 3 and prevent it from loosening, a locking bolt 9 is installed at the front end of the L-shaped support plate 6. An elongated hole 10 is provided on the pull-down locking plate 7, gradually descending from front to back. The locking bolt 9 passes through the elongated hole 10, and as the pull-down locking plate 7 moves downwards, its rear side gradually presses against the alignment square tube 3. The inclined design of the elongated hole 10 allows the pull-down locking plate 7 to gradually press against the alignment square tube 3 through the cooperation of its inclined elongated hole 10 and the locking bolt 9, achieving a reliable locking effect. This locking method is simple to operate and requires no complex tools for locking and unlocking.
[0018] Furthermore, to prevent the pull-down locking plate 7 from damaging the surface of the alignment square tube 3 when pressing it, and to enhance the friction between them and prevent the alignment square tube 3 from sliding, a buffer pad is adhered to the rear side of the pull-down locking plate 7. The buffer pad can be made of elastic materials such as rubber or silicone, which not only protects the alignment square tube 3, but also reduces the collision and wear between the alignment square tube 3 and the pull-down locking plate 7 in a vibration environment, thus extending the service life of the components.
[0019] During use, firstly, according to the design dimensions of the concrete wall, several template units 1 are spliced together in sequence so that the fixing plates 5 of adjacent template units 1 fit together and the fixing holes 2 on adjacent template units 1 correspond one-to-one; then, M10 fixing bolts are passed through the corresponding fixing holes 2 and nuts are tightened to fix adjacent template units 1 together to form a template structure; in the above manner, six layers of template structure are assembled in sequence (taking six layers as an example).
[0020] Then, install the alignment square tube 3. The alignment square tube 3 is made of galvanized square tube, and its length is the same as the length of each layer of template structure. Install the alignment square tube 3 on the outer wall of each layer of template structure. The alignment square tube 3 is set horizontally and located at the upper part of the height direction of each layer of template structure. Fix the alignment square tube 3 to the side wall of template unit 1 by locking piece 4. The specific operation is as follows: 1. The L-shaped support plate 6 in the locking component 4 is made of bent steel plate; a through hole matching the fixing hole 2 is opened at the rear end (horizontal section) of the L-shaped support plate 6, and the fixing bolt is passed through the through hole and the fixing holes 2 of the two adjacent template units 1 to fix the L-shaped support plate 6 to the side wall of the template unit 1. 2. The pull-down locking plate 7 is made of steel plate. An elongated hole 10 is opened on the pull-down locking plate 7. The elongated hole 10 gradually slopes downward from front to back, with an inclination angle of 15°. A rubber buffer pad with a thickness of 5mm is attached to the rear side of the pull-down locking plate 7. 3. Place the pull-down locking plate 7 above the vertical section of the L-shaped support plate 6, so that the M8 locking bolt 9 installed at the front end of the L-shaped support plate 6 passes through the elongated hole 10 on the pull-down locking plate 7. At this time, a receiving cavity 8 is formed between the rear side of the pull-down locking plate 7, the rear upper surface of the L-shaped support plate 6, and the front side of the template unit 1. Place the alignment square tube 3 into the receiving cavity 8. In this embodiment, each template structure is equipped with three sets of locking parts 4 on the left, middle, and right sides. Then pull down the pull-down locking plate 7. Due to the elongated hole 10, With the inclined design of 0, as the pull-down locking plate 7 moves downward, its rear side gradually approaches and presses against the alignment square tube 3. When the buffer pad of the pull-down locking plate 7 is tightly fitted with the alignment square tube 3 and the alignment square tube 3 cannot move, tighten the nut on the locking bolt 9 to fix the pull-down locking plate 7 and complete the installation of the alignment square tube 3. It should be noted here that a diagonal support rod should be installed between the front side of the template unit 1 and the ground. This application only protects the connection structure, so the relevant content of the diagonal support rod is not described.
[0021] After the concrete pouring is completed and reaches the specified strength, the formwork is dismantled. First, unscrew the nuts on the locking bolts 9, push the pull-down locking plate 7 upward to separate the pull-down locking plate 7 from the alignment square tube 3, and then remove the alignment square tube 3. Next, unscrew the fixing bolts connecting the adjacent formwork units 1 and dismantle each formwork unit 1 in sequence. Finally, clean and inspect the dismantled formwork units 1, alignment square tubes 3, locking parts 4, and other components. Intact components can be used for the next construction.
[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
