Description

Technical Field

[0001] This invention relates to building construction, specifically to formwork for openings in shear wall structures. Background Technology

[0002] Wastewater treatment plants are typically connected by multiple functional tanks, which provide corresponding functions according to different steps.

[0003] These types of functional pools require construction by pre-reserving structural holes in the shear wall to connect adjacent functional pools. However, the area below the structural hole is generally a vibration blind zone, making it difficult to achieve proper vibration. If vibration is insufficient, the bottom wall of the structural hole is easily eroded when water flows through it, severely affecting its service life. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a shear wall structure opening formwork that can improve the erosion resistance after the structural opening is formed, eliminate the defects of vibration blind zone, and extend service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shear wall structure opening formwork, comprising a wall formwork and a structural opening formwork located on the wall formwork for forming the structural opening. The structural opening formwork has a vibration hole on one side of the formwork corresponding to the bottom, and also includes an opening and closing assembly. The vibration hole opening and closing assembly includes a base plate mounted on the formwork and a rotatable sealing plate mounted on the base plate. The base plate has a through hole communicating with the vibration hole. The sealing plate rotates on the base plate to open and close the through hole. Pre-embedded reinforcing bars are provided within the space enclosed by the wall formwork. The base plate is mounted on the structural opening formwork via a tie rod. One end of the tie rod hooks the pre-embedded reinforcing bar, and the other end presses the base plate onto the structural opening formwork.

[0006] As a further improvement of the present invention, at least one side of the mountain-shaped clip on the tie rod abuts against the substrate to press the substrate down onto the structural hole template.

[0007] As a further improvement of the present invention, the substrate is provided with a connecting hole for the pull rod to pass through, the pull rod passes through the connecting hole, and the two sides of the mountain-shaped clip on the pull rod abut against two positions near the diagonal of the substrate.

[0008] As a further improvement of the present invention, the sealing plate is provided with a handle, which is formed by a protrusion on the surface of the sealing plate.

[0009] As a further improvement of the present invention, the substrate is connected to the structural hole template by a connecting bolt;

[0010] The connecting bolt includes a bolt body and a bolt cap that is detachably connected to the bolt body. The bolt body is provided with a threaded hole at the position corresponding to the bolt cap. The bolt cap is provided with a screw that mates with the threaded hole, or the bolt cap is provided with a through hole at the position corresponding to the threaded hole.

[0011] The bolt body includes a fitting part and an abutment part. The fitting part has a central assembly hole for mounting the abutment part and allowing the abutment part to extend and retract. The abutment part has a connecting post positioned opposite the assembly hole. The connecting post slides and retracts within the assembly hole, and the threaded hole is located at the end of the connecting post. Deformable support members are provided on both sides of the connecting post. When the connecting post extends and retracts within the assembly hole, the support members abut against the fitting part. The space between the fitting part and the bolt cap is used to clamp the base plate and the structural hole template.

[0012] As a further improvement of the present invention, the support member and the connecting column form an acute angle, and the support member and the connecting part form a mating contact.

[0013] As a further improvement of the present invention, the ends of the two support members corresponding to the connecting columns are also provided with limiting members facing each other. When the support member is attached to the fitting part and deformed to the appropriate position, the limiting members abut against each other to limit the maximum deformation range of the support member.

[0014] As a further improvement of the present invention, a retaining edge is provided at one end of the fitting part corresponding to the support member, and the retaining edge has the fitting part surrounding the support member.

[0015] As a further improvement of the present invention, the flange is flared on the side facing the support member.

[0016] As a further improvement of the present invention, the included angle between the support member and the connecting column forms a space for concrete to enter.

[0017] The beneficial effects of this invention are that the cooperation between the base plate and the sealing plate allows for the pre-reservation of vibration holes in the structural hole template, which can be opened and closed as needed, alleviating the problems of grout overflow and leakage. Furthermore, the cooperation between the tie rod and the embedded reinforcing steel allows for more stable base plate assembly, and the elasticity of the embedded reinforcing steel also improves the sealing effect and reduces the possibility of loosening.

[0024] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0025] Reference Figure 1-5 As shown,

[0026] A shear wall structure opening formwork includes a wall formwork 1 and a structural opening formwork 2 located on the wall formwork 1 for forming the structural opening. The structural opening formwork 2 has a vibration hole on one side of the formwork corresponding to the bottom, and also has an opening and closing component 3. The vibration hole opening and closing component 3 includes a base plate 31 installed on the formwork and a sealing plate 32 rotatably installed on the base plate 31. The base plate 31 has a through hole communicating with the vibration hole. The sealing plate 32 rotates on the base plate 31 to open and close the through hole. The space enclosed by the wall formwork 1 is provided with embedded steel bars 4. The base plate 31 is installed on the structural opening formwork 2 by a tie rod 6. One end of the tie rod 6 hooks the embedded steel bars 4, and the other end presses the base plate 31 onto the structural opening formwork 2.

[0027] In this design, vibration holes are pre-drilled on the structural opening formwork 2, and these holes are sealed using the opening and closing assembly 3 to prevent grout leakage and overflow. During use, a frame of embedded reinforcing bars 4 is first erected, and a casting template is then built outside the embedded reinforcing bars 4 using the structural opening formwork 2. The positions of the vibration holes on the structural opening formwork 2 are then installed using a base plate 31, which seals the vibration holes. The rotatable sealing plate 32 is then rotated to seal the through-holes on the base plate 31 that connect to the vibration holes. Pouring is then carried out into the formwork. After pouring, the sealing plate 32 is opened to expose the through-holes, and a vibrator is inserted through these holes for vibration. After vibration, the sealing plate 32 is rotated back to seal the through-holes.

[0028] In this design, the base plate 31 is pressed against the structural opening template 2 by the tie rod 6, resulting in a better sealing effect. Since the embedded reinforcing steel 4 itself has a certain deformation capacity, it can deform to a certain extent while being pulled together by the tie rod 6, creating an elastic force. This reduces the impact of vibration during compaction. The elastic force also improves the sealing effect and reduces the possibility of loosening. The tie rod 6 can be a three-section detachable design, increasing its recyclability. Specifically, one end of the structural opening template 2 can be reclaimed. Alternatively, a standard tie rod 6 can be used, which can be cut after casting.

[0029] Based on this scheme, the following two clamping methods are provided:

[0030] 1. At least one side of the U-shaped clip on the tie rod 6 abuts against the substrate 31 to press the substrate 31 down onto the structural hole template 2. In this pressing method, the U-shaped clip of the tie rod 6 can simply press the edge of the substrate 31, for example, two tie rods 6 can be used to correspond to the two sides of the substrate 31 respectively, and the two sides of the substrate 31 can be pressed down by the U-shaped clip.

[0031] 2. The substrate 31 is provided with a connecting hole for the pull rod 6 to pass through. The pull rod 6 passes through the connecting hole, and the two sides of the U-shaped clip on the pull rod 6 abut against two positions near the diagonal of the substrate 31. In this pressing method, the contacts on both sides of the U-shaped clip of the pull rod 6 press down on the diagonal of the substrate 31. It is possible to press down on both sides of the substrate 31 simultaneously through one pull rod 6, which is less costly. Moreover, the U-shaped clip itself can be recycled, so even if the size of the U-shaped clip is increased, the cost will not increase significantly.

[0032] In addition, to facilitate operation of the sealing plate 32, a handle 321 is provided on the sealing plate 32, which is formed by a protrusion on the surface of the sealing plate 32.

[0033] The aforementioned clamping method involves clamping the pull rod 6. To facilitate the positioning and initial installation of the substrate 31, the following alternative method is also provided:

[0034] The substrate 31 is connected to the structural hole template 2 via connecting bolts 5;

[0035] The connecting bolt 5 includes a bolt body 51 and a bolt cap 52 detachably connected to the bolt body 51. The bolt body 51 is provided with a threaded hole 515 at the position corresponding to the bolt cap 52. The bolt cap 52 is provided with a screw that mates with the threaded hole 515 or a through hole is provided on the bolt cap 52 at the position corresponding to the threaded hole 515.

[0036] The bolt body 51 includes a fitting part 511 and an abutting part 512. The fitting part 511 has a central mounting hole 513 for mounting the abutting part 512 and for the abutting part 512 to move telescopically. The abutting part 512 is provided with a connecting post 514 at the position of the mounting hole 513. The connecting post 514 slides telescopically within the mounting hole 513, and the threaded hole 515 is located at the end of the connecting post 514. Deformable support members 516 are provided on both sides of the connecting post 514. When the connecting post 514 moves telescopically within the mounting hole 513, the support members 516 abut against the fitting part 511. The space between the fitting part 511 and the bolt cap 52 is used to clamp the base plate 31 and the structural hole template 2.

[0037] In this scheme, the connecting bolt 5 can pre-install the base plate 31 and the structural hole template 2. The bolt body 51 and the bolt cap 52 cooperate to press the structural hole template 2 and the base plate 31. The bolt body 51 and the bolt cap 52 can be tightened by the screw on the bolt cap 52, or the bolt cap 52 can be installed by the through hole and the threaded hole 515 and the bolt.

[0038] The fitting portion 511 of the bolt body 51 is located inside the structural hole template 2, and the bolt cap 52 is located on the surface of the base plate 31. During assembly, the fitting portion 511 fits inside the structural hole template 2, and the abutting portion 512 cooperates with the fitting portion 511 to press the fitting portion 511 onto the structural hole template 2. The mounting hole 513 of the fitting portion 511 allows the connecting post 514 to extend and retract. Specifically, the bolt cap 52 cooperates with the connecting post 514. As the screw or bolt on the bolt cap 52 engages with the threaded hole 515 on the connecting post 514, the connecting post 514 will extend and retract within the mounting hole 513. As the connecting post 514 moves toward the bolt cap 52, the support member 516 on the connecting post 514 will abut against the fitting portion 511 and press the fitting portion 511 tightly onto the structural hole template 2. As the connecting post 514 moves, the support member 516 will deform, generating a greater contact force with the fitting portion 511, thereby stabilizing the connection between the two and performing pre-installation. This installation structure, compared to directly using bolts and washers for installation, has an auxiliary effect in resisting earthquakes.

[0039] Furthermore, the bolt body 51 and bolt cap 52 can be made of plastic, while the screw or bolt part can be made of metal. Plastic itself has a certain degree of deformation and elasticity, so it has better shock resistance when assembled.

[0040] Preferably, the support member 516 and the connecting column 514 form an acute angle, and the support member 516 and the connecting column 514 form a mating contact. The angle between the support member 516 and the connecting column 514 forms a space for concrete to enter.

[0041] The acute angle between the support members generates a deformation elastic force in the support member 516. After the support member 516 abuts against the mating part 511, it will spread apart on both sides. At this time, the elastic force generated by the deformation can react on the mating part 511, supporting the mating part 511. After the concrete enters the space, as vibration is carried out, the slurry at this location will buffer the vibration. Even if the vibrator touches the base plate 31, causing the base plate 31 to transmit vibration, the slurry in the space can still buffer the vibration.

[0042] The ends of the two support members 516 corresponding to one end of the connecting column 514 are also provided with limiting members 517 facing each other. When the support member 516 is attached to the fitting part 511 and deformed to the correct position, the limiting members 517 abut against each other to limit the maximum deformation range of the support member 516.

[0043] When the two support members 516 spread outwards, one end of the limiting member 517 will move closer to each other. When the two limiting members 517 abut together, they can limit the support member 516 from continuing to deform, or in other words, increase the difficulty of deformation of the support member 516. At this time, the abutting force will be further increased, and the clamping effect will be better.

[0044] Additionally, a retaining edge 518 is provided at one end of the fitting portion 511 corresponding to the support member 516, and the retaining edge 518 surrounds the fitting portion 511 towards the support member 516. This surround increases the strength of the fitting portion 511, thereby improving the fitting effect. The retaining edge 518 forms a flared opening on the side facing the support member 516.

[0045] The above-described extrusion scheme using support member 516 overcomes the problem of unevenness in the template. The support member 516 has a small contact surface, and the plastic-made bonding part 511 further reduces the area of ​​force application, thus mitigating the problem of poor bonding caused by template unevenness during contact. The plastic bonding part 511 has a certain deformation capacity; therefore, the combination of the smaller contact surface of the support member 516 and the bonding part 511 allows for a smaller deformation area in the bonding part 511, making it easier to deform and resulting in a better effect.

[0046] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
