Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a formwork reinforcement system. Background Technology

[0002] When pouring concrete for components such as walls and columns, formwork needs to be erected. The formwork on both sides is usually reinforced by tie rods. For example, Chinese utility model patent CN203334678U discloses an external wall formwork reinforcement system for concrete pouring.

[0003] Because tie rods need to penetrate both sides of the formwork of the component to be poured during installation, holes must be drilled in the formwork for the tie rods to pass through. This drilling reduces the strength of the formwork, making it prone to deformation or even damage during concrete pouring, resulting in a short service life. Furthermore, since the reinforcement locations for different components may vary, frequent drilling in the formwork significantly reduces its turnover rate and versatility. Therefore, a formwork reinforcement system is needed to address the problems of reduced formwork strength, turnover rate, and versatility associated with the existing method of drilling holes in the formwork to install tie rods. Summary of the Invention

[0004] The purpose of this utility model is to provide a template reinforcement system that can solve the problems of reduced template strength, turnover rate and versatility caused by the reinforcement method of drilling holes and installing tie bolts on templates in the prior art.

[0005] This utility model is implemented as follows:

[0006] A formwork reinforcement system includes unit formwork, columns, connecting plates, joint strips, and water-stop tie rods. A pair of columns are vertically installed at both ends of the component to be poured. The two ends of the unit formwork are respectively installed on the pair of columns through connecting plates, so that several unit formwork pieces are vertically spliced ​​between the pair of columns along the surface of the component to be poured. Joint strips are connected between two adjacent unit formwork pieces, so that several unit formwork pieces are connected to form a formwork body through the joint strips, and the two ends of the joint strips extend horizontally to connect with the pair of columns. Water-stop tie rods pass through the joint strips and reinforce the formwork body located on both sides of the component to be poured.

[0007] The seam strip includes a seam strip body, a limiting plate, and a card; the seam strip body is fitted into the gap between two adjacent unit templates, and a pair of limiting plates are respectively set at the top and bottom of the inner edge of the seam strip body, so that the pair of limiting plates can abut against the inner wall of the two adjacent unit templates respectively; the card is movably fitted into the outer side of the seam strip body, and the upper and lower ends of the card can abut against the outer wall of the two adjacent unit templates respectively.

[0008] The outer side of the main body of the seam strip is formed with a C-shaped groove, and the middle of the card is formed with a K-shaped slider. The K-shaped slider can be slidably engaged in the C-shaped groove, so that the card can be slidably engaged in the outer side of the main body of the seam strip and can abut against the outer wall of the two adjacent unit templates.

[0009] The main body of the seam strip, the C-shaped groove, and the limiting plate are an integral structure with the same length.

[0010] The joint strip is staggered from the reinforcing bars in the component to be poured. Several bolt holes are formed at intervals on the main body of the joint strip, so that the water-stop tie rod passes through the bolt holes, passes through the joint strip, and reinforces the connection between the template body on both sides of the component to be poured. The water-stop tie rod abuts against the inner wall of the joint strip and seals the bolt holes.

[0011] The joint strip is staggered from the reinforcing bars in the component to be poured. The joint strip is composed of several joint unit strips. There is a gap between two adjacent joint unit strips so that the water-stop tie rod passes through the gap and reinforces the connection between the template body on both sides of the component to be poured. The water-stop tie rod abuts against the inner wall of the joint strip and seals the gap.

[0012] The water-stop tie rod is equipped with a water-stop plate, which is located between the joint strips on both sides of the component to be poured.

[0013] The connecting plate has an L-shaped structure. One end of the connecting plate is attached to the side of the column near the unit template, and the outer wall of the unit template is detachably connected to the other side of the connecting plate.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model features unit templates and joint strips. The upper and lower unit templates are spliced ​​together by the joint strips. Bolt holes are opened on the main body of the joint strips, or the main body of the joint strips is segmented to install water-stop tie rods. This not only meets the installation requirements of water-stop tie rods, but also avoids drilling holes in the unit templates. It solves the problem that drilling holes in the templates to install tie rods reduces the template strength, turnover rate, and versatility. Furthermore, the standardized unit templates are easy to produce and manufacture, convenient to assemble and disassemble on site, have a long service life, and high turnover rate and versatility.

[0016] 2. This utility model features a joint strip. The inner side of the joint strip is attached to the inner wall of two adjacent unit templates via a limiting plate, while the outer side of the joint strip is attached to the outer wall of two adjacent unit templates via a clip. This ensures the reliability of the connection between adjacent unit templates, thereby connecting all unit templates into a high-strength template body. This helps to ensure the quality of concrete pouring for the components to be poured, speeds up the construction progress, and allows the joint strip to be replaced individually if damaged, saving costs.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Please see the appendix Figure 1 To be continued Figure 5 A template reinforcement system includes unit templates 1, columns 2, connecting plates 3, joint strips 4, and water-stop tie rods 5. A pair of columns 2 are vertically installed at both ends of the component to be poured. The two ends of the unit templates 1 are respectively installed on the pair of columns 2 through the connecting plates 3, so that several unit templates 1 are vertically spliced ​​between the pair of columns 2 along the surface of the component to be poured. The joint strips 4 are connected between two adjacent unit templates 1, so that several unit templates 1 are connected to form a template body through the joint strips 4, and the two ends of the joint strips 4 extend horizontally to connect with the pair of columns 2. The water-stop tie rods 5 pass through the joint strips 4 and reinforce the template body located on both sides of the component to be poured.

[0027] Preferably, the unit template 1 can be a standardized template made of high-strength materials such as aluminum alloy or steel plate, and can be modularly spliced ​​according to the size of the component to be poured. The size of the unit template 1 can be adaptively adjusted according to the installation position of the water-stop tie rod 5, so that the water-stop tie rod 5 is not installed on the unit template 1, and the water-stop tie rod 5 is located at the joint position of the adjacent unit template 1, that is, at the joint strip 4.

[0028] Preferably, the column 2 can be made of square steel pipe, and the column 2 can adopt an integral structure or a segmented splicing structure. The column 2 can be selected according to the height adaptability of the component to be poured. The connecting plate 3 can be made of aluminum alloy or steel plate, and is used to connect the column 2 and the unit template 1, and serves to fix the unit template 1.

[0029] Preferably, the joint strip 4 can be made of plastic, which has good structural strength and can connect two adjacent unit templates 1 into a whole. It also facilitates drilling holes in the joint strip 4 for inserting the water-stop tie rods 5, thus avoiding the problems of reducing the strength, turnover rate, and versatility of the unit template 1 due to drilling holes in it. The joint strip 4 can be replaced individually when damaged, resulting in low cost. The water-stop tie rods 5 are used to tie and reinforce the formwork on both sides of the component to be poured.

[0030] Please see the appendix Figure 6 The seam strip 4 includes a seam strip body 42, a limiting plate 43, and a card 44. The seam strip body 42 is fitted into the gap between two adjacent unit templates 1. A pair of limiting plates 43 are respectively set at the top and bottom of the inner edge of the seam strip body 42, so that the pair of limiting plates 43 can abut against the inner wall of the two adjacent unit templates 1 respectively. The card 44 is movably fitted into the outer side of the seam strip body 42, and the upper and lower ends of the card 44 can abut against the outer wall of the two adjacent unit templates 1 respectively.

[0031] Preferably, the thickness of the joint strip body 42 can be adapted to the joint width of two adjacent unit templates 1 to ensure that the two adjacent unit templates 1 are seamlessly spliced ​​through the joint strip body 42.

[0032] The inner side of the joint strip body 42 is abutted against the inner walls of the two adjacent unit templates 1 by the top and bottom limiting plates 43, respectively, which serves to limit the inner side of the unit template 1, ensuring the reliability of the connection between the two adjacent unit templates 1, and also preventing grout leakage during concrete pouring, which would affect the quality of the pouring. Preferably, the limiting plate 43 is relatively thin to ensure a reliable connection between the two unit templates 1 without affecting the quality of the concrete pouring.

[0033] Multiple cards 44 are spaced apart on the main body 42 of the seam strip, and the number and spacing of the cards 44 can be adaptively adjusted according to the connection strength and stress conditions. The cards 44 abut against the outer walls of the two adjacent unit templates 1, which serves to limit the outer side of the unit template 1 and further ensure the connection reliability of the two adjacent unit templates 1.

[0034] Please see the appendix Figure 6 A C-shaped groove 45 is formed on the outer side of the main body 42 of the seam strip, and a K-shaped slider 46 is formed in the middle of the card 44. The K-shaped slider 46 is slidably engaged in the C-shaped groove 45, so that the card 44 can be slidably engaged in the outer side of the main body 42 of the seam strip and can abut against the outer wall of the two adjacent unit templates 1.

[0035] The C-shaped groove 45, with a C-shaped cross-section, forms a constriction at the opening, which can reliably engage the K-shaped slider 46 to prevent it from falling off. The K-shaped slider 46 can slide along the C-shaped groove 45 to adjust the position of the card 44 relative to the unit template 1, ensuring the connection and limiting of the two adjacent unit templates 1.

[0036] Please see the appendix Figure 6 The main body 42 of the seam strip, the C-shaped groove 45 and the limiting plate 43 are an integral structure with the same length.

[0037] Preferably, the joint strip body 42, C-shaped groove 45, and limiting plate 43 can be integrally molded from plastic injection molding, resulting in high structural strength and resistance to deformation and damage. The lengths of the joint strip body 42, C-shaped groove 45, and limiting plate 43 can be determined based on the length of the unit template 1.

[0038] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 7 The joint strip 4 is staggered from the reinforcing steel 6 in the component to be poured. The joint strip body 42 of the joint strip 4 has several bolt holes 41 formed at intervals, so that the water-stop tie rod 5 passes through the bolt holes 41, penetrates the joint strip 4 and reinforces the connection between the template body on both sides of the component to be poured. The water-stop tie rod 55 has a water-stop end 51 against the inner wall of the joint strip 4 and seals the bolt holes 41.

[0039] The joint strip 4 should be positioned offset from the transverse reinforcing bars 6 within the component to be poured, to avoid interference from the transverse reinforcing bars 6 with the installation of the water-stop tie rods 5. Bolt holes 41 are made in the main body 42 of the joint strip 4, avoiding the need for drilling holes in the unit formwork 1 while still meeting the installation requirements of the water-stop tie rods 5. After installation, the water-stop tie rods 5 abut against the inner wall of the joint strip 4 through the water-stop end 51, sealing the bolt holes 41 to prevent leakage and ensure the desired concrete pouring effect.

[0040] Preferably, the main body 42 of the seam strip can adopt a long strip structure with a rectangular cross section, which has high structural strength and is not easily damaged or broken after the hole is opened.

[0041] The joint strip 4 is staggered from the reinforcing steel 6 in the component to be poured. The joint strip 4 is composed of several joint unit strips. There is a gap between two adjacent joint unit strips so that the water-stop tie rod 5 passes through the gap and reinforces the connection between the template body on both sides of the component to be poured. The water-stop end 51 of the water-stop tie rod 5 abuts against the inner wall of the joint strip 4 and seals the gap.

[0042] To avoid affecting the structural strength of the joint strip body 42 after opening a hole, a segmented joint strip 4 can be used. This involves cutting the joint strip 4 into multiple segments according to the installation position of the water-stop tie rod 5, forming joint unit strips. The width of the gap between the joint unit strips is determined by the size of the water-stop tie rod 5. After installation, the water-stop tie rod 5 abuts against the inner wall of the joint strip 4 through its water-stop end 51, sealing the gaps between adjacent joint unit strips to prevent leakage and ensure the desired concrete pouring effect.

[0043] Please see the appendix Figure 7 The water-stop tie rod 5 is provided with a water-stop plate 52. The water-stop plate 52 is located between the joint strips 4 on both sides of the component to be poured, and plays the role of water-stopping, ensuring the anti-seepage and waterproof performance of the component to be poured after concrete pouring.

[0044] Please see the appendix Figure 5 The connecting plate 3 has an L-shaped structure. One end of the connecting plate 3 is attached to the side of the column 2 near the unit template 1. The outer wall of the unit template 1 is detachably connected to the other side of the connecting plate 3 by bolts.

[0045] Preferably, the connecting plate 3 can be an angle bracket, used to connect the column 2 and the unit template 1 via bolts. The connecting plate 3 has a large contact area with the column 2 and the unit template 1, resulting in high connection reliability. Multiple connecting holes are evenly spaced on the connecting plate 3, the column 2, and the unit template 1. The installation height of the connecting plate 3 on the column 2 and the unit template 1 can be adjusted appropriately through the connecting holes at different positions to achieve optimal connection strength. The bolt and connecting hole connection method facilitates assembly and disassembly, improving construction efficiency and accelerating the construction progress.

[0046] Please see the appendix Figure 1 To be continued Figure 7 The construction method and working principle of this utility model are as follows:

[0047] Vertical columns 2 are installed at both ends of the component to be poured. The first unit template 1 is installed between the pair of columns 2 and the ground. The outer walls of both sides of the first unit template 1 are connected and fixed to the columns 2 with bolts through the connecting holes via connecting plates 3. The unit templates 1 and columns 2 on both surfaces of the component to be poured are installed symmetrically in the same way, which will not be described in detail here, thus forming a concrete pouring space for the component to be poured between the two unit templates 1.

[0048] The first joint strip 4 is installed on the top surface of the first unit template 1. The installation method for the integral joint strip 4 is as follows: Bolt holes 41 are made on the main body 42 of the joint strip according to the installation position of the water-stop tie rod 5. The main bodies 42 of the joint strip on both surfaces of the component to be poured are symmetrically installed on the top of the first unit template 1. The installation method for the split joint strip 4 is as follows: The main bodies 42 of the joint strip on both surfaces of the component to be poured are symmetrically installed on the top of the first unit template 1, and a gap is left between adjacent joint strips for the water-stop tie rod 5 to pass through and be installed according to the installation position of the water-stop tie rod 5.

[0049] The second unit template 1 is installed between the joint strip body 42 of the first joint strip 4 and a pair of columns 2, so that the inner walls of the first unit template 1 and the second unit template 1 are fitted against the upper and lower limiting plates 43 of the first joint strip 4, and the second unit template 1 is connected to the columns 2 by the connecting plate 3. Then, the card 44 of the first joint strip 4 is slidably engaged into the C-shaped groove 45 on the outside of the joint strip body 42 by the K-shaped slider 46, so that the upper and lower ends of the card 44 are fitted against the outer walls of the first unit template 1 and the second unit template 1, connecting the first unit template 1 and the second unit template 1 into a whole.

[0050] The water-stop tie bolt 5 passes through the bolt hole 41 or gap into the joint strip 4 on both sides of the component to be poured, and the water-stop tie bolt 55 abuts against and seals the bolt hole 41 or gap of the joint strip body 42 from the inside. The water-stop plate 52 is located in the concrete pouring space of the component to be poured, and plays a role in stopping water.

[0051] Next, install the second joint strip 4 on top of the second unit template 1. The installation method of the second joint strip 4 is the same as that of the first joint strip 4, and will not be repeated here.

[0052] Repeat the above steps until all unit templates 1 are assembled. All unit templates 1 are connected into a whole template body by columns 2, connecting plates 3, joint strips 4 and water-stop tie bolts 5, and then concrete can be poured for the component to be poured.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
