Description

Technical Field

[0001] This application relates to the field of building construction technology, specifically to a shear wall thickness control device. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are a type of wall primarily designed to withstand horizontal loads caused by wind or earthquakes. Shear walls are typically made of reinforced concrete, and the thickness of the shear wall and the thickness of the concrete cover within it are key factors affecting the wall's safety. The concrete cover refers to the concrete structure between the outermost reinforcing bars and the shear wall surface. Currently, during shear wall construction, the internal concrete strip bracing method and the external concrete block hanging method are commonly used to support and secure the shear wall formwork.

[0003] The concrete strip bracing method involves pre-placing concrete bracing strips on the wall's reinforcing steel frame. The length of these strips controls the distance between the formwork on both sides, ensuring the wall thickness meets design requirements. However, this method is unsuitable for thick shear walls. This is because for thicker shear walls, this method requires increasing the size and number of concrete bracing strips to enhance rigidity, resulting in larger and more numerous strips, which is inconvenient for on-site implementation and operation.

[0004] The external concrete spacer method involves placing spacers on the outermost reinforcing bars inside the wall. The thickness of the spacers controls the distance between the vertical reinforcing bars and the formwork, thus ensuring that the wall thickness and protective layer thickness meet design requirements. However, this method requires a large number of spacers, making it difficult to control the quality of the spacers themselves. The stability of the installation by workers and the quantity per square meter are largely influenced by human factors. Furthermore, the spacers are prone to detachment during formwork installation and concrete pouring, affecting the final product quality. Utility Model Content

[0005] The purpose of this application is to provide a shear wall thickness control device to solve the problems that the concrete strip internal bracing method is not suitable for thicker walls and the concrete pad external hanging method affects the wall forming quality.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] A shear wall thickness control device includes two opposing templates and a reinforcing steel cage between the two templates. A through tie rod is provided on the two templates, and a tensioning component is provided at each end of the tie rod. Two template positioning components are provided on the tie rod, and the two template positioning components contact the inner surfaces of the two templates respectively. The tie rod is also provided with a reinforcing steel positioning component for positioning the reinforcing steel cage along its axial direction.

[0008] Furthermore, the rebar positioning assembly includes two rebar positioning elements connected to the tie rod; the two rebar positioning elements are disposed on both sides of the rebar skeleton and in contact with the rebar skeleton, or the two rebar positioning elements are disposed inside the rebar skeleton and in contact with the rebars inside the rebar skeleton.

[0009] Furthermore, the rebar positioning component includes a rebar positioning block, which is connected to the tie rod via a first adjustable structure.

[0010] Furthermore, the first adjustable structure includes a first nut, which is sleeved on the pull rod and threadedly connected to the pull rod, and the reinforcing bar positioning block is connected to the first nut.

[0011] Furthermore, the template positioning component includes a template positioning block, which is connected to the pull rod via a second adjustable structure.

[0012] Furthermore, the second adjustable structure includes a second nut, which is fitted onto the pull rod and threadedly connected to the pull rod, and the template positioning block is connected to the second nut.

[0013] Furthermore, the tie rod includes a tie screw.

[0014] Furthermore, a water-stop steel plate located within the reinforcing steel frame is connected to the tie rod.

[0015] Furthermore, the outer surface of the template is provided with secondary ribs extending in the horizontal direction, and the secondary ribs are provided with main ribs extending in the vertical direction, and the tensioning assembly is disposed on the main ribs.

[0016] Furthermore, the tensioning assembly includes a fastening nut threadedly connected to the pull rod and a butterfly buckle fitted on the pull rod and located between the fastening nut and the main rib.

[0017] The beneficial effects of this application are:

[0018] The shear wall thickness control device provided in this application embodiment, by setting a tie rod penetrating two templates and installing a tensioning component and a template positioning component on the tie rod, can position the template using the tensioning component and the template positioning component, preventing the template from moving along the axial direction of the tie rod, thereby controlling the distance between the two templates and ensuring that the shear wall thickness meets the design requirements; by setting a rebar positioning component on the tie rod to position the rebar skeleton located between the two templates, preventing the rebar skeleton from moving along the axial direction of the tie rod, it can control the distance between the outermost rebar in the shear wall and the shear wall surface, thereby ensuring that the thickness of the concrete cover meets the design requirements.

[0019] The tie rods of this application possess higher strength and stiffness, facilitating on-site implementation and operation even without increasing the size and number of tie rods for thicker shear walls. This solves the problem that the concrete strip internal bracing method is unsuitable for thicker walls. The tensioning components, formwork positioning components, and rebar positioning components of this application can be firmly connected to the tie rods, preventing them from easily detaching during concrete pouring. This enables accurate positioning of the formwork and rebar cage, ensuring the quality of wall formation and resolving the issue of the external concrete pad method affecting wall formation quality.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] See Figure 1 This application provides a shear wall thickness control device, including two opposing templates 10 and a steel reinforcement cage 11 disposed between the two templates 10. The two templates 10 are provided with through tie rods 12, and tensioning components 13 are respectively provided at both ends of the tie rods 12. The tie rods 12 are provided with two template positioning components 14, which are respectively in contact with the inner surfaces of the two templates 10. The tie rods 12 are also provided with steel reinforcement positioning components 15 for positioning the steel reinforcement cage 11 along its axial direction.

[0043] Specifically, two formwork panels 10 are set opposite each other, forming a space between them for pouring concrete. The distance between the inner surfaces of the two formwork panels 10 is the thickness of the shear wall. The formwork panels 10 can be wooden or steel. The reinforcing steel cage 11 is a complete grid formed by binding main bars and stirrups together, also known as a reinforcing cage. The reinforcing steel cage 11 is generally prefabricated and bound in advance, and is directly hoisted as a whole into the space between the two formwork panels 10 during construction. The distance between the outermost reinforcing bar of the reinforcing steel cage 11 and the inner surface of the formwork panel 10 is the thickness of the concrete cover.

[0044] Tie rod 12 penetrates two formwork panels 10 along the thickness direction of the shear wall. Each formwork panel 10 has a tie rod hole for the tie rod 12 to pass through. Both ends of the tie rod 12 are located outside the two formwork panels 10 and are connected to two tensioning components 13 respectively. Two formwork positioning components 14 are also provided on the tie rod 12, contacting the inner surfaces of the two formwork panels 10 respectively. This allows the formwork panels 10 to be clamped by the cooperation of the tensioning components 13 and the formwork positioning components 14, achieving positioning of the inner and outer sides of the formwork panels 10 and preventing movement of the formwork panels 10 on the tie rod 12. A rebar positioning component 15 is also provided on the tie rod 12, located between the two formwork panels 10, and positions the rebar cage 11, preventing the rebar cage 11 from moving axially along the tie rod 12. The number and position of the tie rods 12 should be set according to construction specifications, as long as the construction requirements are met; no specific limitations are made here.

[0045] See Figure 5 During shear wall construction, the shear wall thickness control device provided in this application embodiment is first used to fix the formwork 10 and the reinforcing steel cage 11, and then concrete is poured between the two formwork 10s. During the concrete pouring process, the distance between the two formwork 10s and the distance between the outermost reinforcing steel of the reinforcing steel cage 11 and the inner surface of the formwork 10 remain unchanged, which can improve the forming quality of the shear wall.

[0046] The shear wall thickness control device provided in this application embodiment, by setting a tie rod 12 that penetrates two templates 10, and setting a tensioning component 13 and a template positioning component 14 on the tie rod 12, can use the tensioning component 13 and the template positioning component 14 to position the template 10, prevent the template 10 from moving axially along the tie rod 12, and achieve the purpose of controlling the distance between the two templates 10, thereby ensuring that the thickness of the shear wall meets the design requirements; by setting a rebar positioning component 15 on the tie rod 12 to position the rebar skeleton 11 set between the two templates 10, and prevent the rebar skeleton 11 from moving axially along the tie rod 12, achieve the purpose of controlling the distance between the outermost rebar in the shear wall and the shear wall surface, thereby ensuring that the thickness of the concrete protective layer meets the design requirements.

[0047] The tie rod 12 of this application has higher strength and stiffness than the concrete internal bracing strip. For thicker shear walls, even without increasing the size and number of tie rods 12, it is convenient for on-site implementation and operation, solving the problem that the concrete internal bracing method is not suitable for thicker walls. The tensioning component 13, formwork positioning component 14, and rebar positioning component 15 of this application can be firmly connected to the tie rod 12 and are not easy to fall off during concrete pouring. This enables accurate positioning of the formwork 10 and rebar cage 11, ensuring the quality of wall formation and solving the problem that the external concrete pad method affects the quality of wall formation.

[0048] In some embodiments, the rebar positioning component 15 can be an integral structure, which can be made of steel materials such as rebars, steel plates, and structural steel, and its specific structure and shape are not limited. In use, the rebar positioning component 15 is placed inside the rebar cage 11 and contacts the rebars on both sides of the rebar cage 11, thereby positioning the rebar cage 11 by means of the rebar positioning component 15.

[0049] In some embodiments, see Figure 1 , Figure 2 The rebar positioning assembly 15 includes two rebar positioning elements 151 connected to the tie rod 12. The two rebar positioning elements 151 are disposed on both sides of the rebar cage 11 and in contact with the rebar cage 11, or the two rebar positioning elements 151 are disposed inside the rebar cage 11 and in contact with the rebars inside the rebar cage 11. The rebar positioning elements 151 may include positioning bars, positioning blocks, or positioning plates, etc. Accordingly, by setting the rebar positioning assembly 15 to two rebar positioning elements 151, the cooperation of the two rebar positioning elements 151 not only achieves the positioning of the rebar cage 11, but also reduces the size and space occupied by the rebar positioning assembly 15. Especially in space-constrained situations, the smaller size improves the convenience and flexibility of operation.

[0050] In some embodiments, see Figure 4 The rebar positioning component 151 includes a rebar positioning block 1511, which is connected to the tie rod 12 via a first adjustable structure. Correspondingly, there may be rebar cages 11 of various sizes on the construction site. The first adjustable structure allows adjustment of the position of the rebar positioning block 1511 on the tie rod 12, enabling the rebar cage 11 to be positioned using the rebar positioning block 1511, thus meeting the requirements for positioning rebar cages 11 of different sizes.

[0051] For example, the first adjustable structure may include an internal threaded hole on the rebar positioning block 1511 and an external threaded section on the tie rod 12. The tie rod 12 passes through the internal threaded hole of the rebar positioning block 1511, and the internal threaded hole is threadedly connected to the external threaded section. In use, the position of the rebar positioning block 1511 on the tie rod 12 can be adjusted by rotating the rebar positioning block 1511.

[0052] For example, see Figure 4 The first adjustable structure may further include a first nut 1512, which is sleeved on the tie rod 12 and threadedly connected to it. A rebar positioning block 1511 is connected to the first nut 1512. Correspondingly, the tie rod 12 has an external thread section that mates with the first nut 1512. By rotating the first nut 1512, the rebar positioning block 1511 can be moved axially along the tie rod 12 to adjust its position on the tie rod 12. The rebar positioning block 1511 can be plate-shaped, rod-shaped, or other shapes, as long as it can position the rebar cage 11; no specific limitation is made here.

[0053] In some embodiments, see Figure 3 The template positioning component 14 includes a template positioning block 141, which is connected to the tie rod 12 via a second adjustable structure. Correspondingly, the shear walls at the construction site may have various thicknesses. The second adjustable structure allows adjustment of the position of the template positioning block 141 on the tie rod 12, enabling the template positioning block 141 to position the inner side of the template 10, thus fulfilling the requirement for positioning templates 10 for shear walls of different thicknesses.

[0054] For example, the second adjustable structure may include an internal threaded hole on the template positioning block 141 and an external threaded section on the pull rod 12. The pull rod 12 passes through the internal threaded hole of the template positioning block 141, and the internal threaded hole is threadedly connected to the external threaded section. In use, the position of the template positioning block 141 on the pull rod 12 can be adjusted by rotating the template positioning block 141.

[0055] For example, see Figure 3 The second adjustable structure includes a second nut 142, which is fitted onto the pull rod 12 and threadedly connected to it. A template positioning block 141 is connected to the second nut 142. Correspondingly, the pull rod 12 has an external thread section that mates with the second nut 142. By rotating the second nut 142, the template positioning block 141 can be moved axially along the pull rod 12 to adjust its position on the pull rod 12. The template positioning block 141 can be plate-shaped, rod-shaped, or other shapes, as long as it can position the template 10; no specific limitation is made here.

[0056] In some embodiments, the tie rod 12 may be made of reinforcing bars or steel rods. For example, the tie rod 12 includes a tie screw. The tie screw can be purchased directly from the market and used immediately without further processing.

[0057] In some embodiments, see Figure 1 A water-stop steel plate 16 located within the reinforcing steel frame 11 is connected to the tie rod 12. For example, the water-stop steel plate 16 is fitted onto the tie rod 12 and welded to it. After the shear wall construction is completed, the water-stop steel plate 16 can block the water seepage path, preventing water from seeping from one side of the shear wall to the other.

[0058] In some embodiments, see Figure 1 The outer surface of the template 10 is provided with secondary ribs 17 extending horizontally, and a main rib 18 extending vertically is provided outside the secondary ribs 17. A tensioning assembly 13 is disposed on the main rib 18. Exemplarily, the tensioning assembly 13 includes a fastening nut 131 threadedly connected to the pull rod 12, and a butterfly buckle 132 sleeved on the pull rod 12 and located between the fastening nut 131 and the main rib 18. Accordingly, the secondary ribs 17 and the main rib 18 work together to enhance the rigidity and stability of the template 10. In use, tightening the fastening nut 131 allows the two templates 10 to be tensioned via the pull rod 12.

[0059] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
