Description

Technical Field

[0001] This utility model belongs to the field of building construction, and specifically relates to a temporary reinforcement device for construction at the external corner of wall formwork. Background Technology

[0002] In the construction industry, formwork engineering is a crucial step in concrete structure construction, and the quality of formwork reinforcement directly affects the molding quality of concrete components. During construction, temporary fixation is required for the external corners of the formwork. Traditional temporary fixation methods include wire binding and simple clamps. These methods cannot guarantee the reinforcement effect when the formwork is closed or the verticality between formwork sections. Furthermore, during concrete pouring, the concrete exerts lateral pressure on the formwork. Traditional temporary fixation methods are often structurally rudimentary and have poor load-bearing capacity, making it difficult to effectively resist the lateral pressure of the concrete. This leads to loosening of the formwork and deformation or misalignment of the external corner formwork, thus affecting the molding quality of the concrete external corners. Utility Model Content

[0003] To address the aforementioned problems in existing technologies—namely, the inability of traditional temporary formwork fixing methods to guarantee reinforcement during formwork closure and the verticality between formwork sections, making it difficult to effectively resist the lateral pressure of concrete, leading to formwork loosening and deformation / misalignment of the external corner formwork, thus affecting the forming quality of the concrete external corner—this utility model provides a temporary reinforcement device for the construction of external corners of wall formwork. It includes a first reinforcement component for reinforcing the external corners of the formwork. Four formwork sections are provided, each corresponding to one of the four vertical surfaces of the reinforcing mesh. Adjacent formwork sections are perpendicular to each other and abut against each other. Multiple first reinforcement components are evenly spaced along the vertical direction. Each first reinforcement component includes a first clamp and a first connector. Two first clamps are provided, each located at one of two adjacent external corners. Each first clamp has two mutually perpendicular inner surfaces, which abut against the formwork surfaces on both sides of the external corner. The first connector is used to connect and tighten the two first clamps along the horizontal direction.

[0004] Furthermore, the first connecting member includes a first screw and a first nut, and a first sleeve is horizontally provided on the first clamping member. The first sleeves on the two first clamping members are coaxial, and the first screw passes through the two first sleeves and is threadedly engaged with the first nut.

[0005] Furthermore, the four templates are all provided with a fixing part on their outer sides. Multiple fixing parts are equally spaced along the vertical direction. Each fixing part includes four steel pipes corresponding to the four templates. The steel pipes are horizontally arranged and close to each other to press the four templates from the periphery towards the center. Adjacent steel pipes are perpendicular to each other and connected by fasteners. The fixing part also includes a second reinforcing component for reinforcing the four steel pipes. The second reinforcing component includes a second clamp and a second connector. Two second clamps are provided and located at two adjacent external corners. The second clamp has a U-shaped inner groove. Two opposing steel pipes are located in the inner grooves of the two second clamps. The second connector is used to connect and tighten the two second clamps in the horizontal direction.

[0006] Furthermore, the first connecting member includes a second screw and a second nut, and a second sleeve is provided on the second clamp. The second sleeves on the two second clamps are coaxial, and the second screw passes through the two second sleeves and is threadedly engaged with the second nut.

[0007] Furthermore, the openings of the two second card slots are positioned opposite each other.

[0008] Furthermore, the template includes two first plates and two second plates, the horizontal dimension of the first plates is larger than the horizontal dimension of the second plates, and the first and second reinforcing components are both set corresponding to the second plates.

[0009] Furthermore, a wooden strip is provided between the first plate and the steel pipe on its outer side. The wooden strip is long and vertically positioned. The inner side of the wooden strip abuts against the first plate, and the outer side abuts against the steel pipe.

[0010] Furthermore, multiple timber beams are evenly spaced along the horizontal direction.

[0011] Furthermore, the fixing part and the first reinforcing component are alternately arranged in the vertical direction.

[0012] Furthermore, the fixing part is located in the middle of the line connecting two adjacent first reinforcing components.

[0013] The beneficial effects of this utility model are:

[0014] (1) The first clamp abuts against the template surfaces on both sides of the external corner. The first connector connects and tightens the two first clamps in the horizontal direction to temporarily reinforce the templates corresponding to the two adjacent external corners, ensuring the reinforcement effect when the templates are closed and the verticality between the templates. In addition, during the concrete pouring process, it can effectively resist the lateral pressure of the concrete on the template, and to a certain extent avoid the template from loosening and the external corner template from deforming or misaligning, thereby improving the forming quality of the concrete external corner.

[0015] (2) Four steel pipes are brought close to each other to squeeze the four templates from the periphery to the center. The steel pipes are connected in sequence by fasteners. At the same time, two steel pipes facing each other are located in the inner grooves of two second clamps respectively. The second connector connects the two second clamps in the horizontal direction and tightens them, thereby doubly reinforcing the four steel pipes. This can avoid the phenomenon of fastener slippage and loosening to a certain extent, improve the stability of the steel pipes, further ensure the rigidity and stability of the entire wall template system, reduce the risk of template bulging and running, and improve the construction quality.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 8 As shown, this utility model provides a temporary reinforcement device for construction at the external corner of a wall formwork 2, including a first reinforcement component 3 for reinforcing the external corner of the formwork 2. Four formwork 2s are provided and correspond to the four vertical surfaces of the steel mesh 1 respectively. Two adjacent formwork 2s are perpendicular to each other and abut against each other. Multiple first reinforcement components 3 are provided at equal intervals along the vertical direction. The first reinforcement component 3 includes a first clamp 31 and a first connector. Two first clamps 31 are provided and are located at two adjacent external corners respectively. The first clamp 31 has two mutually perpendicular inner surfaces. The two inner surfaces of the first clamp 31 abut against the surfaces of the formwork 2 on both sides of the external corner respectively. The first connector is used to connect and tighten the two first clamps 31 in the horizontal direction.

[0028] The first clamp 31 abuts against the surfaces of the template 2 on both sides of the external corner. The first connector connects and tightens the two first clamps 31 in the horizontal direction to temporarily reinforce the template 2 corresponding to the two adjacent external corners, ensuring the reinforcement effect when the template 2 is closed and the verticality between the templates 2. In addition, during the concrete pouring process, it can effectively resist the lateral pressure of the concrete on the template 2, and to a certain extent avoid the template 2 from loosening and the external corner template 2 from deforming and misaligning, thus improving the forming quality of the concrete external corner.

[0029] In one embodiment, see Figure 5 and Figure 6 The first connecting member includes a first screw 33 and a first nut 34. A first sleeve 32 is horizontally provided on the first clamp 31. The first sleeves 32 on the two first clamps 31 are coaxial. The first screw 33 passes through the two first sleeves 32 and is threadedly engaged with the first nut 34 to improve the efficiency of installation and disassembly of the two first clamps 31, thereby improving the efficiency of disassembly and assembly of the template 2.

[0030] The first sleeve 32 is welded and fixed to the first clamp 31.

[0031] In one embodiment, the four templates 2 are provided with a fixing part on their outer side. Multiple fixing parts are provided at equal intervals along the vertical direction. Each fixing part includes four steel pipes 6 corresponding to the four templates 2 respectively. The steel pipes 6 are horizontally arranged and the four steel pipes 6 are close to each other to squeeze the four templates 2 from the periphery to the center. Two adjacent steel pipes 6 are perpendicular to each other and connected by fasteners 7.

[0032] The fixing part also includes a second reinforcing component 5 for reinforcing the four steel pipes 6. The second reinforcing component 5 includes a second clamp 51 and a second connector. Two second clamps 51 are provided and are located at two adjacent external corners respectively. The second clamp 51 has a U-shaped inner groove. The two steel pipes 6 facing each other are located in the inner grooves of the two second clamps 51 respectively. The second connector is used to connect and tighten the two second clamps 51 in the horizontal direction.

[0033] Existing technologies typically reinforce steel pipes 6 using only fasteners 7. However, the fasteners 7 have limited locking force, and under significant lateral concrete pressure, they may slip or loosen, reducing the stability of the steel pipes 6 and consequently affecting the rigidity and stability of the entire wall formwork 2 system, increasing the risk of formwork bulging and displacement. In this invention, four steel pipes 6 are brought close together to compress the four formwork 2 from the periphery towards the center. The steel pipes 6 are connected sequentially by fasteners 7. Simultaneously, two opposing steel pipes 6 are located within the inner grooves of two second clamps 51. A second connecting piece horizontally connects and tightens the two second clamps 51, thus providing double reinforcement to the four steel pipes 6. This effectively prevents slippage and loosening of the fasteners 7, improves the stability of the steel pipes 6, further ensures the rigidity and stability of the entire wall formwork 2 system, reduces the risk of formwork bulging and displacement, and improves construction quality.

[0034] It is worth noting that the first clamp 31 is cut from angle steel commonly found on construction sites, and the second clamp 51 can be cut from channel steel commonly found on construction sites, making them convenient to manufacture and use, and with low operating costs. Additionally, the fastener 7 is used to connect two vertical steel pipes 6. It includes an arc-shaped body, ear plates, and a bolt structure. The curvature of the inner wall of the arc-shaped body matches the diameter of the steel pipe, used to clamp the surface of the upper steel pipe 6, providing clamping force and friction. The ear plates extend from both sides of the arc-shaped body and have holes. The ear plates on the two arc-shaped bodies are aligned and overlapped. The bolt structure passes through the holes on the two ear plates, and after tightening, it connects the two vertical steel pipes 6. The structure and working principle of the fastener 7 are existing technologies and will not be elaborated here.

[0035] In one embodiment, see Figure 7 and Figure 8 The first connecting member includes a second screw 53 and a second nut 54. A second sleeve 52 is provided on the second clamp 51. The second sleeves 52 on the two second clamps 51 are coaxial. The second screw 53 passes through the two second sleeves 52 and is threadedly engaged with the second nut 54 to improve the efficiency of installation and disassembly of the two second clamps 51, thereby further improving the disassembly and assembly efficiency of the template 2.

[0036] The second sleeve 52 is welded and fixed to the second clamp 51.

[0037] In one embodiment, the openings of the inner grooves of the two second clamps 51 are arranged opposite to each other to further enhance the reinforcement stability of the steel pipe 6 by the second clamps 51.

[0038] In one embodiment, the template 2 includes two first plates and two second plates, the horizontal dimension of the first plates is larger than the horizontal dimension of the second plates, and the first reinforcing component 3 and the second reinforcing component 5 are both corresponding to the second plates.

[0039] By setting the first reinforcing component 3 and the second reinforcing component 5 only at the narrower template 2, the temporary reinforcement of the template 2 and the reinforcement of the steel pipe 6 can be achieved. This saves on the amount of the first reinforcing component 3 and the second reinforcing component 5 used while ensuring the reinforcement effect and improving construction efficiency.

[0040] In one embodiment, a wooden strip 4 is provided between the first plate and the outer steel pipe 6. The wooden strip 4 is long and vertically arranged. The inner side of the wooden strip 4 abuts against the first plate and the outer side abuts against the steel pipe 6.

[0041] Timber 4 serves as a vertical keel, supporting and reinforcing the first board, thereby improving its rigidity and stability in the vertical direction.

[0042] In one embodiment, multiple wooden blocks 4 are arranged at equal intervals along the horizontal direction to further enhance the rigidity and stability of the first board in the vertical direction.

[0043] In one embodiment, the fixing part and the first reinforcing component 3 are alternately arranged in the vertical direction.

[0044] While ensuring the rigidity and stability of the entire wall formwork system, the placement of the reinforcement structure is optimized.

[0045] In one embodiment, the fixing part is located in the middle of the line connecting two adjacent first reinforcing components 3.

[0046] In use, this invention first installs the template 2 to the outside of the reinforcing mesh 1 according to the layout lines, ensuring that the template 2 corresponds to the four vertical surfaces of the reinforcing mesh 1, and that adjacent templates 2 are perpendicular to each other and abut against each other. The first clamp 31 abuts against the surfaces of the templates 2 on both sides of the external corner. The first screw 33 and the first nut 34 connect and tighten the two first clamps 31 in the horizontal direction, temporarily reinforcing the templates 2 corresponding to the two adjacent external corners, ensuring the reinforcement effect when the templates 2 are closed and the verticality between the templates 2. Furthermore, during concrete pouring, it effectively resists the lateral pressure exerted by the concrete on the template 2, to a certain extent preventing the template 2 from loosening and the external corner templates 2 from deforming or misaligning, thus improving the forming quality of the concrete external corner.

[0047] After the first reinforcing component 3 temporarily fixes the four external corners of the template 2, nails are used to fix the external corner template 2. After fixing, the first reinforcing component 3 can be removed for reuse. Then, vertical keel timber 4 is placed on the outside of the template 2 as a support and reinforcement for the template 2. Steel pipes 6 are installed on the outside of the timber 4 as horizontal main keel reinforcement. Adjacent steel pipes 6 are connected by fasteners 7. At the same time, two steel pipes 6 facing each other are located in the inner grooves of two second clamps 51 respectively. The second screw 53 and the second nut 54 connect and tighten the two second clamps 51 in the horizontal direction, thereby providing double reinforcement for the four steel pipes 6. This can, to a certain extent, prevent the fasteners 7 from slipping or loosening, improve the stability of the steel pipes 6, further ensure the rigidity and stability of the entire wall template 2 system, reduce the risk of template 2 bulging and running, and improve the construction quality.
