Description

Technical Field

[0001] This utility model belongs to the field of prefabricated wall preparation technology, specifically relating to a reusable shear wall keyway mold. Background Technology

[0002] Precast shear walls are an essential component in prefabricated building systems. Keyways are typically installed at the junctions of precast shear walls and cast-in-place concrete sections to allow for shared load-bearing between the precast shear wall and the subsequent concrete, resulting in good stability and load-bearing capacity. In current manufacturing processes, precast shear walls are typically constructed using templates on a mold platform to build the casting frame and then cast. Keyway steel modules are integrally welded onto the templates. After casting and curing, these modules form grooves on the corresponding sides of the precast shear wall, creating the keyways. This process is simple and reliable. However, because the keyway molds are welded to the side molds, they cannot be reused after a project ends, requiring new purchases for each new project, leading to high production costs.

[0003] Chinese patent CN219445458U discloses a green molding template and mold for prefabricated shear wall keyways, which includes a baffle and a keyway block. It further discloses that the keyway block is secured to the front of the baffle with screws, allowing the baffle and keyway block to be combined according to design and reused repeatedly. Different sizes of shear walls require different numbers and sizes of keyways. However, in the aforementioned patent document, the position of the keyway locking holes on the baffle and the size of the keyway block are fixed, making it unsuitable for shear walls of different sizes. Therefore, there is an urgent need to design a reusable shear wall keyway mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a reusable shear wall keyway mold to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reusable shear wall keyway mold, comprising:

[0006] A baffle, wherein the baffle has a strip-shaped opening extending to one end, and two symmetrical sliding grooves are provided on the inner side wall of the baffle. One end of the baffle has an insertion hole and a sealing plate is inserted and fixed thereto. One side of the baffle has an insertion hole and a mounting plate is inserted and fixed thereto. The mounting plate has a strip-shaped hole corresponding to the strip-shaped opening.

[0007] A keyway block is provided, which is set in a strip-shaped through-hole and slidably connected to a slide groove. The keyway block includes a splicing block one and a splicing block two. One end of the splicing block one is provided with a tenon, and one end of the splicing block two is provided with a mortise that matches the tenon. Both the upper and lower sides of the keyway block are provided with insertion plates that match the slide groove. One side of the keyway block is provided with a connecting rod corresponding to the strip-shaped hole.

[0008] Furthermore, a scale is provided on one side of the mounting plate, and the scale is arranged parallel to the top of the strip hole, with the length of the scale being the same as the length of the strip opening.

[0009] Furthermore, a limiting block is provided inside the strip-shaped opening, and the two ends of the limiting block are slidably connected to the corresponding sliding grooves. The limiting block is disposed between two adjacent keyway blocks.

[0010] Furthermore, a sealing plate is fixedly connected to one side of both the limiting block and the plug-in plate, and the sealing plate fits into the groove of the slide.

[0011] Furthermore, a connecting rod is provided on one side of the keyway block. One end of the connecting rod passes through the strip hole and extends to one side of the mounting plate. A gasket is sleeved on the end of the connecting rod, and it is fixedly connected to the mounting plate through a connecting ring.

[0012] Furthermore, the connecting rod includes splicing rod one and splicing rod two, both of which have a semi-circular cross-section with the same radius. Splicing rod one and splicing rod two are respectively fixed to one side of splicing block one and splicing block two.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] This utility model provides, for example Figure 1-6 The reusable shear wall keyway mold shown includes:

[0026] A baffle 100 has a strip-shaped opening 101 extending to one end. The inner side wall of the baffle 100 has two symmetrical sliding grooves 102. One end of the baffle 100 has an insertion hole 103 and a sealing plate 104 is inserted and fixed thereto. One side of the baffle 100 has an insertion hole 105 and a mounting plate 106 is inserted and fixed thereto. The mounting plate 106 has a strip-shaped hole 107 corresponding to the strip-shaped opening 101.

[0027] A keyway block 200 is disposed within the strip-shaped through-hole 101 and slidably connected to the slide groove 102. The keyway block 200 includes a first splicing block 201 and a second splicing block 202. One end of the first splicing block 201 is provided with a tenon 203, and one end of the second splicing block 202 is provided with a mortise 204 that matches the tenon 203. Both the upper and lower sides of the keyway block 200 are provided with insertion plates 205 that match the slide groove 102. One side of the keyway block 200 is provided with a connecting rod 206 that corresponds to the strip-shaped hole 107.

[0028] In this technical solution, both splicing block 1 201 and splicing block 202 are provided with modules of various lengths. By selecting splicing blocks 1 201 and splicing block 202 of different lengths for splicing, keyway blocks 200 of different sizes can be obtained to meet the needs of shear walls of different sizes.

[0029] For example, see Figure 2 As shown, a scale 108 is provided on one side of the mounting plate 106. The scale 108 is arranged parallel to the top of the strip hole 107, and the length of the scale 108 is the same as the length of the strip opening 101.

[0030] In this technical solution, by setting a scale 108, the position of the keyway block 200 on the baffle 100 can be accurately located, thereby ensuring that the keyway position on the precast shear wall meets the requirements.

[0031] For example, see Figures 1-3As shown, a limiting block 109 is provided in the strip-shaped opening 101. The two ends of the limiting block 109 are slidably connected to the corresponding sliding groove 102. The limiting block 109 is disposed between two adjacent keyway blocks 200.

[0032] In this technical solution, the two ends of the limiting block 109 slide within the slide groove 102, making it easy to move the limiting block 109 to any position within the strip opening 101. The two sides of the limiting block 109 abut against the sides of two adjacent keyway blocks 200, which can limit the keyway blocks 200 to prevent them from shifting in the left and right directions, and also prevent mortar from flowing into the slide groove 102 during the prefabrication of shear walls, thereby affecting the use of the mold.

[0033] For example, see Figure 1 As shown, a sealing plate 110 is fixedly connected to one side of both the limiting block 109 and the plug plate 205, and the sealing plate 110 fits into the groove of the slide 102.

[0034] In this technical solution, the sealing plate 110 is set on the side close to the keyway block 200, which can further prevent mortar from flowing into the slide 102 when prefabricating shear walls, ensuring that the mold is not affected by mortar and can be reused.

[0035] For example, see Figure 1 As shown, a connecting rod 206 is provided on one side of the keyway block 200. One end of the connecting rod 206 passes through the strip hole 107 and extends to one side of the mounting plate 106. A gasket 207 is sleeved on the end of the connecting rod 206 and is fixedly connected to the mounting plate 106 through a connecting ring 208.

[0036] In this technical solution, the connecting rod 206 is fixed to the mounting plate 106 by the connecting ring 208, thereby fixing the keyway block 200 to the baffle 100. By casting the precast shear wall through this mold, a keyway can be formed on one side of the precast shear wall. After demolding, the connecting ring 208 can be unscrewed to remove the keyway block 200 from the baffle 100, thus enabling the keyway block 200 to be reused.

[0037] For example, see Figures 5-6 As shown, the connecting rod 206 includes splicing rod one 2061 and splicing rod two 2062. The cross-sections of splicing rod one 2061 and splicing rod two 2062 are both semi-circular structures with the same radius. Splicing rod one 2061 and splicing rod two 2062 are respectively fixed to one side of splicing block one 201 and splicing block two 202.

[0038] In this technical solution, when two splicing blocks 1 201 and splicing block 202 of any length are connected by mortise and tenon joints, splicing rod 1 2061 and splicing rod 2062 on splicing block 1 201 and splicing block 202 can be combined into a connecting rod 206. By fitting a washer 207 and a connecting ring 208 onto the connecting rod 206, the connection between splicing block 1 201 and splicing block 202 can be made more stable.

[0039] For example, see Figures 3-4 As shown, the side surface of the connecting rod 206 is provided with an L-shaped groove 2063, and the inner side of the connecting ring 208 is provided with a protrusion 2081 that matches the L-shaped groove 2063.

[0040] In this technical solution, when the connecting ring 208 is sleeved on the connecting rod 206, the protrusion 2081 on the connecting ring 208 is first embedded into the L-shaped groove 2063. Then, the connecting ring 208 is slid downward until the protrusion 2081 is at the bottom of the L-shaped groove 2063. Then, the connecting ring 208 is rotated so that the protrusion 2081 enters the transverse groove of the L-shaped groove 2063. At this time, the connecting ring 208 cannot slide upward and disengage from the connecting rod 206, thereby fixing the connecting rod 206 on the mounting plate 106.

[0041] Working principle: When using this reusable shear wall keyway mold, first open the sealing plate 104, then place the keyway block 200 in the strip opening 101, and set a limit block 109 of a specified width between the two keyway blocks 200 according to actual needs. Then, insert the sealing plate 104 into one end of the baffle 100, and then insert the mounting plate 106 into one side of the baffle 100, so that the connecting rod 206 on the keyway block 200 passes through the strip hole 107 on the mounting plate 106. Then, slide the keyway block 200 to the specified position according to the scale 108, and then fit and fix the connecting ring 208 on the connecting rod 206, so that the keyway block 200 is fixed to one side of the baffle 100. This reusable shear wall keyway mold features an advanced design, compact structure, and ease of use. By using connecting rods 206 and connecting rings 208, the keyway block 200 can be fixed to the baffle 100, facilitating assembly and disassembly and enabling the recycling of the keyway block 200. The strip-shaped opening 101 and sliding groove 102 allow the keyway block 200 to be arbitrarily adjusted in position on the baffle 100. Different sizes of keyway blocks 200 can be assembled by using different sized splicing blocks 1 201 and splicing block 202. The scale 108 and limiting block 109 allow for precise control of the spacing between adjacent keyway blocks 200, enabling the prefabrication of shear walls of different sizes according to requirements, demonstrating strong applicability.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
