Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a formwork connection component and a formwork component for preventing grout leakage due to misalignment of joints. Background Technology

[0002] In building construction, the treatment of joints between adjacent formwork is a crucial step in ensuring the quality of concrete structures. Traditionally, adjacent formwork is often fixed using a combination of tie bolts and back-mounted fixing, such as the technology disclosed in CN111411774A. This method involves installing two rows of tie bolts above and below the construction joint and using transverse back-mounted fixing to prevent misalignment and grout leakage. However, this approach has significant drawbacks:

[0003] Installation is complicated: the tie bolts need to pass through the template and be clamped and fixed by two horizontal back clamps. During construction, the back clamps need to be precisely assembled, which is cumbersome and inefficient, especially when space is limited. Utility Model Content

[0004] This application provides a template connection component and a template component for preventing grout leakage at misaligned joints, in order to solve the problems existing in related technologies. The technical solution is as follows:

[0005] In a first aspect, embodiments of this application provide a template connecting component, which is configured between a first template and a second template, wherein the first template and the second template are arranged sequentially along a first direction, and the first template and the second template form a seam, comprising:

[0006] A positioning component includes a limiting plate and a pull plate. The limiting plate is located between the first template and the second template, abutting against the inner walls of both templates. The limiting plate covers the seam and ensures the inner walls of both templates are on the same horizontal plane. The pull plate has a first end integrally connected to the limiting plate and a second end passing through the seam. The pull plate has a connecting hole that penetrates the pull plate.

[0007] A connecting plate is located between the first template and the second template. The connecting plate passes through the connecting hole and is interference-fitted with the connecting hole. The connecting plate abuts against the outer side wall of the first template and the outer side wall of the second template to restrict the limiting plate to abutting against the inner side wall of the first template and the inner side wall of the second template.

[0008] In one embodiment, the connecting plate has a triangular cross-section.

[0009] In one embodiment, the cross-section of the connecting hole is rectangular;

[0010] The connecting plate has a right-angled triangle cross-section, and one side wall of the connecting plate with the right-angled side abuts against the outer side wall of the first template and the outer side wall of the second template.

[0011] In one embodiment, there are multiple connecting holes, and the multiple connecting holes are arranged sequentially along the length extension direction of the seam;

[0012] The number of connecting plates is multiple, and each connecting plate is interference-fitted with the corresponding connecting hole.

[0013] In one embodiment, the limiting plate, the pull plate, and the connecting plate are all structures made of steel.

[0014] In one embodiment, the first end of the pull plate is connected to the limiting plate by spot welding.

[0015] In one embodiment, the width of the limiting plate is 3cm.

[0016] In one embodiment, the width of the pull plate is 5 cm.

[0017] Secondly, embodiments of this application provide a template assembly for preventing grout leakage due to misalignment at joints, including:

[0018] First template;

[0019] A second template, wherein the second template and the first template are arranged sequentially along a first direction, and a seam is formed between the second template and the first template; and

[0020] The template connection component mentioned above.

[0021] The advantages or beneficial effects of the above technical solutions include at least the following:

[0022] This utility model discloses a template connection assembly, including a positioning component and a connecting plate. The positioning component consists of an integrally connected limiting plate and a pull plate, forming a single structure. During installation, the limiting plate in the positioning component directly abuts against the inner walls of both the first and second templates. The pull plate in the positioning component passes through the joint and is fixed by an interference fit with the connecting plate. This simplifies the installation process from "through bolts + double-sided assembly" to a two-step operation of "positioning + insertion," eliminating the need for repeated adjustments to the double-sided positions or tightening of multiple bolts. The installation is simpler and more efficient, making it particularly suitable for work in confined spaces. With the cooperation of the connecting holes of the connecting plate and the pull plate, and the first and second templates, the limiting plate in the positioning component can reliably press the inner walls of the first and second templates together, ensuring that the joint between the first and second templates is covered, thus preventing water leakage. At the same time, it makes the inner walls of the first and second templates on the same horizontal plane, preventing misalignment. In addition, the limiting plate and the connecting plate form an internal and external rigid constraint, ensuring that the inner walls of the first and second templates remain on the same horizontal plane, avoiding misalignment caused by loosening of the traditional backing. At the same time, it ensures that the joint is completely covered by the limiting plate, preventing leakage. Furthermore, by simply adjusting the length of the connecting plate or the position of the pull plate, it can be applied to templates of different thicknesses, making it more versatile.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] See Figures 1-2 This illustration shows a template connecting assembly according to a preferred embodiment of the present invention. The template connecting assembly is configured between a first template 3 and a second template 4, the first template 3 and the second template 4 being arranged sequentially along a first direction, forming a seam, and includes:

[0031] Positioning component 1 includes a limiting plate 11 and a pull plate 12. The limiting plate 11 is located between the first template 3 and the second template 4, abutting against the inner wall of the first template 3 and the inner wall of the second template 4, so that the limiting plate 11 covers the joint and the inner walls of the first template 3 and the second template 4 are on the same horizontal plane. The first end of the pull plate 12 is integrally connected to the limiting plate 11, that is, the positioning component 1 is a one-piece structure. The second end of the pull plate 12 passes through the joint. The pull plate 12 has a connecting hole 121 that penetrates the pull plate 12.

[0032] The connecting plate 2 is located between the first template 3 and the second template 4. The connecting plate 2 has a connecting hole 121 through it. The connecting plate 2 is interference-fitted with the connecting hole 121. The connecting plate 2 abuts against the outer side wall of the first template 3 and the outer side wall of the second template 4, so as to restrict the limiting plate 11 to abut against the inner side wall of the first template 3 and the inner side wall of the second template 4.

[0033] The template connection assembly of this utility model includes a positioning component 1 and a connecting plate 2. The positioning component 1 consists of an integrally connected limiting plate 11 and a pull plate 12, forming an integrated structure. During installation, the limiting plate 11 in the positioning component 1 directly abuts against the inner walls of both the first template 3 and the second template 4. The pull plate 12 in the positioning component 1 passes through the joint and is fixed by the interference fit of the connecting plate 2. That is, only the positioning component 1 needs to be pre-installed between the first template 3 and the second template 4 and the connecting plate 2 needs to be inserted into the connecting hole 121 of the pull plate 12. This simplifies the installation steps from "through bolt + double back-side splicing" to a two-step operation of "positioning + insertion", eliminating the back-side splicing step and eliminating the need to repeatedly adjust the double back-side position or tighten multiple sets of bolts. The installation operation is simpler and the installation efficiency is higher, especially suitable for operation in confined spaces. With the cooperation of the connecting hole 121 of the connecting plate 2 and the pull plate 12, the first template 3 and the second template 4, the limiting plate 11 in the positioning component 1 can reliably press the inner sidewall of the first template 3 and the inner sidewall of the second template 4, ensuring that the joint between the first template 3 and the second template 4 can be covered, thereby preventing water leakage. At the same time, it makes the inner sidewall of the first template 3 and the inner sidewall of the second template 4 on the same horizontal plane, preventing misalignment. In addition, the limiting plate 11 and the connecting plate 2 form an internal and external rigid constraint, ensuring that the inner sidewall of the first template 3 and the inner sidewall of the second template 4 remain on the same horizontal plane, avoiding misalignment caused by loosening of the traditional back side. At the same time, it ensures that the joint is completely covered by the limiting plate 11 to prevent leakage. In addition, only the length of the connecting plate 2 or the position of the pull plate 12 needs to be adjusted to be applicable to templates of different thicknesses, making it more versatile.

[0034] In one embodiment, the connecting plate 2 has a triangular cross-section. The triangular connecting plate 2 has higher bending and torsional stiffness, which can effectively resist the lateral pressure during template pouring, prevent the connecting plate 2 from deforming, and ensure the tightness of the template joint. In addition, the triangular connecting plate 2 can increase the contact pressure with the connecting hole 121, enhance the fastening effect of the interference fit, prevent the connecting plate 2 from loosening, and ensure that the limiting plate 11 can reliably cover the joint. In addition, the sharp corner of the triangular connecting plate 2 can guide the connecting plate 2 to be smoothly inserted into the connecting hole 121 of the pull plate 12, reduce the alignment adjustment time, and improve the installation efficiency. Furthermore, compared with rectangular or circular cross-sections, the triangular structure can reduce the amount of material used under the same strength, reduce manufacturing costs, and reduce the weight of the components, making it easier to handle and install.

[0035] See Figure 2 In one embodiment, the cross-section of the connecting hole 121 is rectangular;

[0036] The connecting plate 2 has a right-angled triangular cross-section. One side of the connecting plate 2 with the right-angled side abuts against the outer side wall of the first template 3 and the outer side wall of the second template 4. The rectangular connecting hole 121 provides a larger contact surface, making the connecting plate 2 more stable when inserted and reducing the risk of shaking. When the hypotenuse of the right-angled triangular connecting plate 2 mates with the rectangular connecting hole 121, a self-locking effect is formed, enhancing the tightness of the interference fit and preventing loosening caused by vibration or pouring impact. Furthermore, the right-angled side of the connecting plate 2 directly abuts against the outer side walls of both the first template 3 and the second template 4, forming a rigid support to prevent template displacement or misalignment. Simultaneously, it allows the lateral pressure of the concrete to be evenly transmitted throughout the connecting assembly, reducing stress concentration and improving resistance to deformation.

[0037] Of course, in other embodiments, the cross-section of the connecting hole 121 can be a suitable shape such as a circle, rectangle or triangle, and the cross-section of the connecting plate 2 can be a circle, rectangle or other suitable shape.

[0038] In one embodiment, there are multiple connecting holes 121, and the multiple connecting holes 121 are arranged sequentially along the length extension direction of the joint.

[0039] The connecting plates 2 consist of multiple pieces, each of which is interference-fitted with a corresponding connecting hole 121. Thus, the multiple connecting holes 121 are evenly distributed along the joint direction, forming a multi-point rigid constraint with the multiple connecting plates 2, effectively dispersing the lateral pressure during concrete pouring and preventing formwork deformation or joint cracking. Furthermore, the synergistic effect of the multiple connecting plates 2 ensures that the load is evenly transferred to the entire joint area, avoiding connection failure or formwork misalignment caused by excessive stress at a single point. Additionally, if one connecting plate 2 is slightly misaligned, the remaining connecting plates 2 can still provide effective support, reducing the impact of construction errors on the overall structure. Moreover, when splicing narrow formwork, the connecting plates 2 can be inserted in sections, allowing for segmented installation and gradual adjustment of positioning, which is particularly suitable for the construction of large-span or curved formwork. During later fine-tuning, individual connecting plates 2 can be added, removed, or replaced, achieving segmented adjustment without the need for overall disassembly.

[0040] In one embodiment, the limiting plate 11, the pull plate 12, and the connecting plate 2 are all made of steel, so that the limiting plate 11, the pull plate 12, and the connecting plate 2 all have excellent tensile, compressive, and bending resistance, and can withstand the high pressure impact during concrete pouring, ensuring the long-term stability and no deformation of the formwork connection components. In addition, the high rigidity of the limiting plate 11, the pull plate 12, and the connecting plate 2 can form a stronger internal and external two-way constraint, effectively preventing formwork misalignment, joint cracking, or leakage. Furthermore, the limiting plate 11, the pull plate 12, and the connecting plate 2, made of steel, are wear-resistant and corrosion-resistant, suitable for repeated use, and reduce long-term construction costs.

[0041] In one embodiment, the first end of the pull plate 12 is connected to the limiting plate 11 by spot welding. This spot welding process firmly connects the pull plate 12 and the limiting plate 11, forming a high-strength, integrated rigid structure with the following advantages: 1. Reliable connection, anti-loosening – Spot welding ensures long-term stability through metallurgical bonding, avoiding the risk of loosening of bolts or rivets and maintaining overall rigid constraint; 2. Precise welding, anti-deformation – The small heat-affected zone effectively controls welding deformation, ensuring the geometric accuracy of the limiting plate 11 and the pull plate 12; 3. Uniform stress distribution, high durability – The integrated structure optimizes load transfer, eliminates stress concentration, and prevents local deformation or breakage; 4. Compact design, suitable for narrow joints – No bolt operation space is required, the structure is more streamlined, and it is particularly suitable for narrow construction scenarios with template joints.

[0042] In one embodiment, the width of the limiting plate 11 is 3cm. The 3cm wide limiting plate 11 has sufficient rigidity to effectively resist the lateral pressure during concrete pouring and prevent the template from deforming or displacing. The thicker limiting plate 11 can press more tightly against the inner wall of the template, ensuring complete coverage of the joints and reducing the risk of grout leakage. The thickened limiting plate 11 is wear-resistant and deformation-resistant, suitable for high-frequency reuse, and reduces the replacement and maintenance costs during long-term construction.

[0043] In one embodiment, the width of the pull plate 12 is 5cm. The 5cm thickened pull plate 12 significantly improves the longitudinal bending resistance and can withstand the lateral pressure of heavy concrete pouring, preventing the pull plate 12 from deforming or breaking. In addition, the thickened pull plate 12 can be configured with more high-strength connection holes 121 to realize modular expansion connection.

[0044] One embodiment of this utility model provides a template assembly for preventing grout leakage due to misalignment at joints, comprising:

[0045] First template 3;

[0046] The second template 4 and the first template 3 are arranged sequentially along a first direction, forming a seam between the second template 4 and the first template 3; and

[0047] The template connection component mentioned above.

[0048] The template assembly of this utility model, due to the adoption of the aforementioned template connection assembly, also allows for direct contact between the limiting plate 11 in the positioning component 1 and the inner walls of both the first template 3 and the second template 4 during installation. The pull plate 12 in the positioning component 1 passes through the joint and is fixed by the interference fit of the connecting plate 2. That is, only the positioning component 1 needs to be pre-installed between the first template 3 and the second template 4, and the connecting plate 2 needs to be inserted into the connecting hole 121 of the pull plate 12. This simplifies the installation process from "through bolts + double-sided assembly" to a two-step operation of "positioning + insertion," eliminating the need for the double-sided assembly step and repeatedly adjusting the double-sided positions or tightening multiple sets of bolts. The installation operation is simpler and more efficient, making it particularly suitable for work in confined spaces. Specifically, the connecting hole 121 between the connecting plate 2 and the pull plate 12... 21. With the cooperation of the first template 3 and the second template 4, the limiting plate 11 in the positioning component 1 can reliably press the inner sidewalls of the first template 3 and the second template 4, ensuring that the joint between the first template 3 and the second template 4 is covered, thereby preventing water leakage. At the same time, it makes the inner sidewalls of the first template 3 and the second template 4 on the same horizontal plane, preventing misalignment. In addition, the limiting plate 11 and the connecting plate 2 form an internal and external rigid constraint, ensuring that the inner sidewalls of the first template 3 and the second template 4 remain on the same horizontal plane, avoiding misalignment caused by loosening of the traditional back side. At the same time, it ensures that the joint is completely covered by the limiting plate 11, preventing leakage. In addition, only the length of the connecting plate 2 or the position of the pull plate 12 needs to be adjusted to be applicable to templates of different thicknesses, making it more versatile.
