Description

Technical Field

[0001] The invention relates to the technical field of special-shaped formwork reinforcement, and in particular to an adjustable hoop structure for reinforcing a vertical component formwork and a construction method thereof. Background Art

[0002] With the development of the construction industry, in order to meet the design requirements of spatial functionality and structural importance, some vertical structural components such as shear walls have L-shaped and T-shaped shear wall structures, and the ends of the shear walls are constrained end columns protruding from the shear walls. There are even some shear walls with short ends or constrained end columns protruding from the shear walls, and the angle formed by the shear walls is not the regular 90 degrees.

[0003] When using formwork safety calculation software to assist in the verification and design of the formwork support system of this part of the shear wall, the design calculation is usually carried out for the entire surface to determine the type and thickness of the formwork in the formwork system, the spacing and size of the small beams, the setting of the large beams and the vertical spacing and other design parameters. However, there are no specific and reliable design measures for how to effectively support and fix the short limbs and the constrained end columns of the protruding shear wall to the shear wall. During the on-site implementation process, usually only simple steel pipes or wooden squares are used for temporary support, which is quite arbitrary. As a result, after pouring concrete, the short limbs such as L-shaped or T-shaped and the constrained end columns of the protruding shear wall are often not firmly fixed, and the forming effect is poor, such as offset or distortion, which affects the quality of concrete molding. Summary of the invention

[0004] The present invention aims to provide an adjustable hoop structure for reinforcing a vertical member formwork and a construction method thereof, so as to solve the problem in the prior art that the formwork of irregular vertical members is difficult to reinforce and thus affects the quality of concrete forming.

[0005] The present invention is achieved by adopting the following technical solutions:

[0006] The present invention provides an adjustable clamp structure for reinforcing a vertical component formwork, comprising a plurality of support rods, all of which are connected end to end and surround the outer side of the vertical component formwork to form a clamp structure; both ends of each of the support rods are provided with connecting holes, and the hole walls of the connecting holes are provided with a plurality of groups of slots; the connecting holes on two adjacent support rods are aligned, sleeves are installed in the connecting holes, and the outer wall of the sleeve is provided with protrusions, which are adapted to the slots and are clamped in the slots.

[0007] As the preferred technical solution:

[0008] Each group of the card slots includes two card slot units, and the two card slot units are respectively located at two ends of a diameter of the connecting hole.

[0009] As the preferred technical solution:

[0010] A group of protrusions is arranged on the outer wall of the sleeve, and the group of protrusions includes two protrusion units, and the two protrusion units are respectively located at two ends of a diameter of the sleeve.

[0011] As the preferred technical solution:

[0012] The clamping grooves are processed at positions with different angles in the circumferential direction of the connecting hole.

[0013] As the preferred technical solution:

[0014] The slots are respectively processed at positions of 0°, 30°, 90°, and 135° on the circumference of the connecting hole.

[0015] As the preferred technical solution:

[0016] A connection point is provided at each corner of the vertical component formwork, and a support rod is connected to another support rod at the connection point.

[0017] As the preferred technical solution:

[0018] A bolt is installed in the sleeve, and the bolt is connected with a nut to lock the two support rods.

[0019] As the preferred technical solution:

[0020] The support rod is made of steel rectangular tube.

[0021] The present invention further provides a construction method for an adjustable hoop structure for reinforcing a vertical member formwork, comprising the following steps:

[0022] S1: Loft the size of vertical components;

[0023] S2: According to the size of the vertical components, process the corresponding support rods, sleeves and bolts;

[0024] S3: Install vertical component formwork;

[0025] S4: Install support rods on the outside of the vertical member formwork;

[0026] S5: Connect two adjacent support rods at the corner of the vertical member formwork, align the connection holes at the ends of the two support rods, pass the sleeves through the connection holes at the ends of the two support rods, install bolts in the sleeves, pass the bolts through the sleeves, and then install nuts on the ends of the bolts and tighten them;

[0027] S6: Inspection and acceptance.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The present invention has strong applicability and can effectively support and reinforce special-shaped vertical structural formworks (such as special-shaped short-leg shear wall formworks) to ensure the stability of the formwork system. Steel rectangular tubes of different sizes can be selected according to the vertical component formworks of different shapes, and then the steel rectangular tubes are connected in sequence to form a hoop structure to support and reinforce the outer side of the vertical component formwork, and the rigidity of the steel rectangular tubes themselves is used to support and fix the formwork.

[0030] 2. The structure of the adjustable hoop structure of the present invention can be flexibly adjusted. When there are L-shaped and T-shaped shear wall structures in vertical structural members such as shear walls, and the ends of the shear walls are restrained end columns protruding from the shear walls, and even some short ends of the shear walls or restrained end columns protruding from the shear walls form an angle that is not a regular 90 degrees with the shear walls, the adjustable hoop structure can effectively support and reinforce these irregular formwork systems.

[0031] 3. Since a connection point is set at each corner of the vertical component formwork, the steel rectangular tube is connected to another steel rectangular tube at the connection point. At the connection point, the steel rectangular tubes are firmly connected by sleeves, bolts and nuts. The connection angle between the steel rectangular tubes can also be adjusted. The adjustment range is determined according to the position of the slot on the steel rectangular tube. After adjustment, it is fixed by the sleeve. The protrusion on the sleeve is stuck in the slots on the two steel rectangular tubes at the same time, limiting the rotation between the two steel rectangular tubes.

[0032] 4. The present invention is implemented in L-shaped and T-shaped shear wall structures and irregular constraint end columns, which solves the problem of difficult formwork reinforcement of irregular structures in engineering projects, simplifies the construction process, reduces repeated reinforcement of this part, reduces the cost of steel pipe rental and tension screws, and at the same time improves the construction efficiency of workers, ensures the quality of concrete pouring, avoids the use of conventional reinforcement methods in the short part of the shear wall, and causes the size of the vertical components to be non-compliant, thereby reducing later repairs and rectifications.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment proposes an adjustable hoop structure for reinforcing a vertical component formwork, including a plurality of support rods 1, all of which are connected end to end and surround the outside of a vertical component formwork 8 to form a hoop structure, and a connection point is set at each corner of the vertical component formwork 8, and the support rod 1 is connected to another support rod 1 at the connection point, and the vertical component formwork 8 is used for pouring concrete. Both ends of each support rod 1 are provided with connection holes 2, and the hole wall of the connection hole 2 is provided with a card slot 3. In this embodiment, as shown in FIG. Figure 4 As shown, a plurality of groups of slots 3 are arranged on the hole wall of the connection hole 2, and each group of slots 3 includes two slot units, and the two slot units are respectively located at the two ends of a diameter of the connection hole 2. The slots 3 are respectively processed at the positions of 0°, 30°, 90°, and 135° in the circumferential direction of the connection hole 2. By reserving the slots 3 at different angles of the connection hole 2, it is convenient to adapt the connection angle between the steel rectangular tubes, and the angle adjustment between the steel rectangular tubes can be realized. The slots 3 are opened at the above-mentioned angles to meet the needs of most engineering construction, but are not limited to these angles. If the angles at the corners of the vertical component template are not the above-mentioned angles, the support rod 1 is further processed to meet the needs of the site.

[0042] like Figure 2 and Figure 3 As shown, the connection holes 2 on the two adjacent support rods 1 are aligned, and then a sleeve 4 is installed in the connection hole 2, the outer diameter of the sleeve 4 is adapted to the inner diameter of the connection hole 2, and the outer wall of the sleeve 4 is provided with a protrusion 5, the protrusion 5 is adapted to the slot 3, and the protrusion 5 can be just stuck in the slot 3, so as to fix the two adjacent support rods 1 and prevent them from rotating. In this embodiment, as Figure 5As shown, a group of protrusions 5 are provided on the outer wall of the sleeve 4 , and the group of protrusions 5 includes two protrusion units, and the two protrusion units are respectively located at two ends of a diameter of the sleeve 4 .

[0043] A bolt 6 is installed in the sleeve 4, and the bolt 6 is connected with a nut 7 to lock the two support rods 1 to ensure the stability of the adjustable clamp structure.

[0044] In this embodiment, the support rod 1 is made of steel rectangular tube, the length of which is determined according to the length of each side of the vertical component template 8, and the steel rectangular tube can be prepared in advance according to the size of the vertical component.

[0045] The adjustable clamp structure provided in this embodiment is adopted, steel rectangular tubes of different sizes are selected according to the vertical component formworks of different shapes, and then the steel rectangular tubes are connected in sequence to form a clamp structure to support and reinforce the outer side of the vertical component formwork, and the rigidity of the steel rectangular tubes themselves is used to support and fix the formwork.

[0046] The structure of the adjustable hoop structure can be flexibly adjusted. When there are L-shaped and T-shaped shear wall structures in vertical structural components such as shear walls, and the ends of the shear walls are restrained end columns protruding from the shear walls, even some short ends of the shear walls or the restrained end columns protruding from the shear walls form an angle that is not a regular 90 degrees with the shear walls. For these irregular formwork systems, the adjustable hoop structure can effectively support and reinforce them, because the adjustable hoop structure includes multiple steel rectangular tubes, and the steel rectangular tubes are provided with connection points at the corners of the vertical component formwork. At the connection points, the steel rectangular tubes are firmly connected by sleeves, bolts and nuts. Relying on the pre-arranged slots on the steel rectangular tubes, the connection angles between the steel rectangular tubes can be quickly adjusted. After adjustment, they are fixed by sleeves. The protrusions on the sleeves are simultaneously stuck in the slots on the two steel rectangular tubes to limit the rotation between the two steel rectangular tubes.

[0047] The present invention is implemented in L-shaped and T-shaped shear wall structures and irregular constraint end column positions, which solves the problem of difficult reinforcement of formworks of irregular structures in engineering projects, simplifies the construction process, reduces repeated reinforcement of the parts, reduces the cost of steel pipe rental and tension screw rods, and at the same time, improves the construction efficiency of workers, ensures the quality of concrete pouring and formation, and reduces later repairs and rectifications.

[0048] The present invention has strong applicability and can effectively support and reinforce special-shaped vertical structural formworks, thereby ensuring the stability of the formwork system.

[0049] The construction method of the adjustable hoop structure provided in this embodiment includes:

[0050] S1: Loft the size of vertical components;

[0051] S2: According to the size of the vertical components, process the corresponding steel tubes, sleeves and bolts;

[0052] S3: Install vertical component formwork;
