Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a temporary fixing device for rebar installation on the upper part of a structural column. Background Technology

[0002] During building construction, structural columns are often installed at specific locations in masonry walls to enhance the wall's integrity and stability. Structural columns, being secondary structures, not only improve the wall's seismic performance but also prevent cracking, playing a crucial role in the building structure. To ensure a reliable connection between the structural columns and the original concrete structure, a rebar anchoring process is often used to tightly connect them. Traditional rebar anchoring involves drilling, cleaning the holes, injecting anchoring adhesive, and inserting the rebar, using the adhesive to firmly anchor the rebar into the concrete structure.

[0003] In actual construction, there are many difficulties in installing rebar on the upper part of the structural column: First, because the anchoring adhesive requires 24 hours to fully cure, the connection between the inserted rebar and the concrete structure is not firm before curing, and it is prone to slipping under its own weight, resulting in insufficient anchorage depth. In severe cases, it may even fall off, posing a certain safety hazard. Second, it is difficult to ensure the verticality of the rebar during the installation process, and the inserted rebar is prone to tilting and deformation. These problems not only increase the construction difficulty but also affect the reliability of the connection between the structural column and the superstructure. Utility Model Content

[0004] To address the aforementioned deficiencies in existing technologies, a temporary fixing device for upper rebar installation in structural columns is provided. This device can fix the upper rebar of the structural column before the rebar adhesive cures, ensuring the verticality of the rebar and preventing it from loosening or falling off.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A temporary fixing device for rebar anchoring on the upper part of a structural column is characterized by comprising a fixing box, a support rod, and a connecting mechanism. The fixing box is fixedly disposed below the upper structure, and the fixing box has a cavity inside and a slot on its lower surface. The support rod is detachably installed in the cavity of the fixing box through the slot. The connecting mechanism is used to connect and fix the rebar anchor and the support rod, and its length can be adjusted according to the distance between the rebar anchor and the support rod.

[0007] According to the above technical solution, the connecting mechanism includes two fasteners and a telescopic member. The two fasteners are respectively located at both ends of the telescopic member and are used to fix the reinforcing bar and the support rod.

[0008] According to the above technical solution, the fastener includes a retaining ring and a bolt. The bolt is disposed on the retaining ring, and the reinforcing bar and the support rod can be fixed in the retaining ring by tightening the bolt.

[0009] According to the above technical solution, the telescopic component includes a fixed rod and a sliding rod. The fixed rod and the sliding rod are connected by a thread, and rotating the sliding rod can adjust the distance between the two fasteners.

[0010] According to the above technical solution, each of the above-mentioned rebars is provided with at least one of the above-mentioned connecting mechanisms.

[0011] According to the above technical solution, the fixing box is bonded and fixed to the upper structure by epoxy resin adhesive.

[0012] According to the above technical solution, the slot on the lower surface of the fixing box is rectangular.

[0013] According to the above technical solution, the support rod is T-shaped and includes a crossbar and a hanging rod. The crossbar can pass through the slot and be inserted into the cavity and fixed by rotation.

[0014] According to the above technical solution, both the fixing box and the support rod are made of plastic.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] like Figure 1-4 As shown, this utility model provides a temporary fixing device for the upper rebar 4 of a structural column, including a fixing box 1, a support rod 2, and a connecting mechanism 3. The fixing box 1 is fixedly installed below the upper structure 6, and the fixing box 1 has a cavity 11 inside and a slot 12 on its lower surface. The support rod 2 is detachably installed in the cavity 11 of the fixing box 1 through the slot 12. The connecting mechanism 3 is used to connect and fix the rebar 4 and the support rod 2, and its length can be adjusted according to the distance between the rebar 4 and the support rod 2. This device achieves the fixing of the rebar 4, which not only ensures the verticality of the rebar 4, but also prevents the rebar 4 from loosening or falling off during construction, thus ensuring the quality and safety of construction.

[0026] In this embodiment, as Figure 2As shown, the connecting mechanism 3 includes two fasteners and a telescopic component. The two fasteners are fixed to both ends of the telescopic component, respectively, for fixing the reinforcing bar 4 and the support rod 2. The telescopic component includes a fixed rod 31 and a sliding rod 32. The fixed rod 31 is sleeved on the outside of the sliding rod 32, and the two are connected by threads. Each fastener includes a U-shaped retaining ring 33 and a bolt 34. One end of the retaining ring 33 is fixedly connected to the telescopic component, and the other end is provided with a bolt 34. The bolt 34 passes through the retaining ring 33. By tightening the bolt 34, the reinforcing bar 4 and the support rod 2 can be firmly fixed in the retaining ring 33.

[0027] In this embodiment, the length of the telescopic component can be adjusted by rotating the sliding rod 32, thereby changing the distance between the two fasteners and flexibly adapting to different spacings between the support rod 2 and the anchor bar 4. To ensure the stability of the anchor bar 4, at least one connecting mechanism 3 is provided for each anchor bar 4. For longer anchor bars 4, a connecting mechanism 3 can be provided at both the upper and lower ends to ensure the verticality of the anchor bar 4 and prevent it from loosening and falling off.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, the fixing box 1 is a hollow structure with an internal cavity 11 and a rectangular slot 12 on its lower surface.

The support rod 2 has a T-shaped structure, with a rectangular crossbar 21 at the top and a cylindrical hanging rod 22 at the bottom. During installation, the crossbar 21 of the support rod 2 is inserted into the cavity 11 inside the fixing box 1 through the slot 12, and then the crossbar 21 is rotated 90° to make it perpendicular to the slot 12, thus fixing the support rod 2. The fixing box 1, support rod 2, and connecting mechanism 3 are all manufactured using a factory prefabrication method and then directly transported to the construction site for assembly and use. The fixing box 1 and support rod 2 are made of plastic, while the connecting mechanism 3 is made of steel.

[0029] In this embodiment, the specific construction process of the fixing device is as follows: First, apply epoxy resin adhesive 5 to the upper surface of the fixing box 1, and then adhere the fixing box 1 to the lower part of the upper structure 6. Next, install the support rod 2 into the fixing box 1. Finally, install the connecting mechanism 3 between the support rod 2 and the rebar 4, and adjust the length of the connecting mechanism 3 to ensure that the rebar 4 remains vertical. After the adhesive on the rebar 4 has cured, the connecting mechanism 3 can be loosened and the support rod 2 can be removed. The fixing box 1 does not need to be recycled. The overall structure of the device is simple, and the installation and disassembly process is convenient and quick, which can greatly improve construction efficiency and progress.
