Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an armpit corner adapter and a ribbed template armpit corner connection structure. Background Technology

[0002] In the field of formwork construction, formwork connection is a crucial link in ensuring construction quality and efficiency, especially at the structural armhole corner, where the connection effect directly affects the overall construction progress and cost control. Currently, traditional formwork connection methods have two major pain points when dealing with the connection between ribbed composite material formwork and flat panels (such as wooden formwork) at the armhole corner.

[0003] On the one hand, traditional connection procedures are complex and cumbersome, often requiring multiple sets of tools for positioning, fixing, and calibration. This not only consumes a lot of manpower but also significantly prolongs construction time, making it difficult to meet the demands of modern construction projects for efficient construction and slowing down the overall project progress. On the other hand, traditional connection methods often rely on forceful tightening or direct welding, which can easily damage the structure of composite material formwork, leading to problems such as cracks and deformation, and significantly reducing the reusability of the formwork. The decline in formwork reusability directly increases the cost of formwork procurement and replacement during construction, exacerbating the economic burden of the project.

[0004] To address the technical pain points of "low efficiency" and "damage to formwork" in the aforementioned traditional construction methods, this application proposes a corner adapter and a ribbed formwork corner connection structure, aiming to meet the needs of building construction for efficient and non-damaging formwork connections. Utility Model Content

[0005] The purpose of this utility model is to provide an axillary corner adapter and a ribbed template axillary corner connection structure to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the first technical solution provided by this utility model is as follows: An underarm corner adapter includes a first strip metal plate, the middle part of which protrudes upward to form a limiting protrusion, and the bottom of the two sides of the limiting protrusion extend in a direction that approaches each other to form limiting shoulders. The top of the first strip metal plate is connected to a second metal plate and a third metal plate arranged in parallel on opposite sides, and the height of the second metal plate is higher than that of the third metal plate. One end of the second metal plate is connected to an L-shaped connecting plate, and the short side of the L-shaped connecting plate is connected to the second metal plate. One end of the third metal plate is connected to a fourth metal plate, and the fourth metal plate is connected to the back of the long side of the L-shaped connecting plate.

[0007] Preferably, the first strip metal plate, the second metal plate, the third metal plate, the L-shaped connecting plate, and the fourth metal plate are integrally formed.

[0008] Preferably, the angle between the second metal plate and the short side of the L-shaped connecting plate is an acute angle, and the fourth metal plate is perpendicularly connected to the back side of the long side of the L-shaped connecting plate.

[0009] Preferably, the long side of the L-shaped connecting plate has a groove along its length.

[0010] Preferably, the cross-section of the top of the limiting protrusion is arc-shaped.

[0011] The second technical solution provided by this utility model is: A ribbed template axle corner connection structure includes two ribbed templates arranged vertically and horizontally respectively, and several limiting handles. The axle corner adapters according to any one of the claims are respectively installed at the ends of the two ribbed templates that are close to each other. A connecting plate is laid between the L-shaped connecting plates of the two axle corner adapters. The ribbed template has a through-hole at one end that matches the limiting protrusion. One end of the limiting handle passes through the mounting hole and is inserted into the limiting protrusion, where it locks the limiting shoulder of the limiting protrusion.

[0012] Preferably, the limiting handle is L-shaped, and a flat limiting head is connected to the long end of the limiting handle, and the cross-sectional shape of the limiting head is adapted to the limiting protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The adapter of this utility model, by setting a limiting protrusion in the middle of the first strip metal plate and limiting shoulders on both sides, can be precisely matched with the mounting holes of the ribbed template, realizing the rapid positioning of the adapter and the ribbed template and avoiding misalignment during the connection process. The L-shaped connecting plate provides installation space for the installation of the connecting plate, making it convenient for the connecting plate to connect the two adapters and realize the non-destructive connection of the template armpit corner.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-6 As shown: Embodiment 1 of this utility model is as follows: like Figure 3-6 As shown, a ribbed template armpit corner connection structure includes two ribbed templates 8 arranged vertically and horizontally respectively, and several limiting handles 9. Armpit corner adapters are respectively installed at the ends of the two ribbed templates 8 that are close to each other, and a connecting plate 10 is laid between the L-shaped connecting plates 6 of the two armpit corner adapters. The ribbed formwork 8 has a through-hole at one end that matches the limiting protrusion 2. One end of the limiting handle 9 passes through the mounting hole and is inserted into the limiting protrusion 2, locking the limiting shoulder 3 of the limiting protrusion 2. By passing the limiting handle through the mounting hole of the ribbed formwork and locking the limiting shoulder, fixation can be completed simply by rotating the handle, without the need for complicated tools, making the operation simple and quick. The structure of the two armhole corner adapters and connecting plates can simultaneously achieve the connection of vertical and horizontal ribbed formwork, shortening the formwork assembly time at the armhole corner and effectively improving construction efficiency. Furthermore, the locking structure of the limiting handle and the limiting shoulder can provide reliable fixing force, preventing the formwork from shifting or loosening during concrete pouring. At the same time, the connecting plate is laid between the two L-shaped connecting plates to form an integral load-bearing structure, further enhancing the overall stability of the formwork at the armhole corner and ensuring the quality of building construction.

[0019] like Figure 1-2As shown, the underarm corner adapter in this embodiment includes a first strip metal plate 1. The middle part of the first strip metal plate 1 protrudes upward to form a limiting protrusion 2. The bottom of the two sides of the limiting protrusion 2 extends in a direction that approaches each other to form a limiting shoulder 3. The top of the first strip metal plate 1 is connected to a second metal plate 4 and a third metal plate 5 arranged in parallel on opposite sides. The height of the second metal plate 4 is higher than that of the third metal plate 5. One end of the second metal plate 4 is connected to an L-shaped connecting plate 6, and the short side of the L-shaped connecting plate 6 is connected to the second metal plate 4. One end of the third metal plate 4 is connected to a fourth metal plate 7, and the fourth metal plate 7 is connected to the back of the long side of the L-shaped connecting plate 6.

[0020] In this embodiment, the first strip metal plate 1, the second metal plate 4, the third metal plate 5, the L-shaped connecting plate 6, and the fourth metal plate 7 are integrally formed. The integral forming process avoids the stress concentration problem caused by welding or bolting in spliced ​​structures, greatly improves the overall structural strength of the adapter, can withstand the pressure and vibration of concrete pouring during construction, and extends the service life of the adapter. In addition, the integral forming process reduces the splicing and assembly of parts, reduces labor and time costs in the production process, and avoids the hidden dangers of easy corrosion and loosening at the splicing points, reducing later maintenance costs and making it more suitable for large-scale industrial production.

[0021] In this embodiment, the angle between the second metal plate 4 and the short side of the L-shaped connecting plate 6 is an acute angle, and the fourth metal plate 7 is perpendicularly connected to the back of the long side of the L-shaped connecting plate 6. The acute angle design between the second metal plate and the short side of the L-shaped connecting plate allows the force at the corner to be evenly transmitted along the inclined surface of the metal plate, avoiding structural deformation caused by excessive local force. The perpendicular connection between the fourth metal plate and the back of the long side of the L-shaped connecting plate can further strengthen the support strength of the L-shaped connecting plate and prevent it from bending under stress.

[0022] In this embodiment, the long side of the L-shaped connecting plate 6 has a groove 61 along the length direction. The groove on the long side of the L-shaped connecting plate can be used as a positioning groove for flat boards (such as bamboo plywood or plastic flat templates) to prevent the boards from sliding during installation.

[0023] In this embodiment, the top of the limiting protrusion 2 has an arc-shaped cross section. The arc-shaped cross section design of the top of the limiting protrusion can prevent sharp edges from scratching or squeezing the template hole wall when it is matched with the ribbed template installation hole, effectively protecting the structural integrity of the ribbed composite material template, improving the template reuse rate, and reducing construction costs.

[0024] In this embodiment, the limiting handle 9 is L-shaped, and a flat limiting head 91 is connected to the long end of the limiting handle 9. The cross-sectional shape of the limiting head 91 is adapted to the limiting protrusion 2. The structure of the L-shaped limiting handle makes it easy for construction personnel to hold and rotate. Only 90° rotation is needed to engage or disengage the limiting head and the limiting shoulder, making the operation simple and efficient. The flat limiting head is adapted to the internal structure of the limiting protrusion, which can tightly engage the limiting shoulder, prevent the handle from loosening, and ensure the reliability of the connection structure. When the template needs to be disassembled after construction is completed, the engagement between the limiting head and the limiting shoulder can be released by simply rotating the L-shaped handle in the opposite direction. There is no need to damage the template or the adapter, which can achieve non-destructive disassembly of the template and the adapter, greatly improving the reuse rate of both and reducing construction costs.

[0025] The specific implementation process of the above embodiments is as follows: Adapter installation stage: First, align the two underarm adapters with the ends of the vertically and horizontally arranged ribbed templates 8 respectively, so that the limiting protrusions 2 are aligned with the preset mounting holes of the templates, until the first strip metal plate 1 is attached to the end of the template, thus completing the initial positioning of the adapters.

[0026] Limit handle fixing stage: Pass the long end of the L-shaped limit handle 9 through the template mounting hole, so that the flat limit head 91 at the end is inserted into the limit protrusion 2. Rotate the handle 90°. At this time, the limit head 91 engages with the limit shoulders 3 on both sides of the limit protrusion 2. The axial movement of the handle is restricted by the blocking effect of the shoulders, so as to achieve quick fixing of the adapter and the ribbed template without the need for additional fasteners. The operation is efficient and does not damage the template.

[0027] Connecting plate laying stage: A connecting plate 10, such as a 15mm thick wooden mold or bamboo plywood, is laid between the L-shaped connecting plates 6 of the two armpit corner adapters, so that the edge of the connecting plate 10 is embedded in the groove 61 of the L-shaped connecting plate 6, and the plate is positioned by the groove; if further fixation is required, nails or bolts can be used to pass through the connecting plate 10 and the L-shaped connecting plate 6, and the groove is used to limit the position of the fasteners to prevent loosening, and finally a stable armpit corner connection structure is formed.

[0028] Disassembly principle: After construction is completed, rotate the L-shaped limit handle 90° in the opposite direction to disengage the limit head 91 from the limit shoulder 3. After pulling out the handle, the adapter can be removed from the template installation hole, realizing non-destructive disassembly of the adapter and the template. Both can be reused, reducing construction costs.
