Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and specifically relates to a temporary fixing clamp for beam-column joint connection in prefabricated buildings. Background Technology

[0002] In the field of prefabricated buildings, with its rapid development, the connection of beam-column joints has become a core element in improving structural performance and construction efficiency. Currently, conventional methods require the erection of full-span scaffolding to provide temporary support for prefabricated components, as well as the installation of formwork for joint grouting. This method has many drawbacks. On the one hand, the construction procedures are complex, resulting in a long construction period; on the other hand, the large amount of materials required significantly increases construction costs, and the site occupancy rate remains high.

[0003] More importantly, existing connection methods suffer from technical challenges such as unstable connections and difficulty in effectively guaranteeing connection quality. These problems severely restrict the further development and widespread application of prefabricated buildings. Therefore, there is an urgent need to design a new type of fixing clamp that can quickly fix beam-column joints during the connection process, thereby significantly improving the stability and safety of the connection and addressing the aforementioned shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a temporary fixing clamp for connecting beam-column joints in prefabricated buildings, which can quickly and securely connect beams and columns.

[0005] The technical solution adopted by this utility model is a temporary fixing clamp for beam-column joint connection in prefabricated buildings, including beam binding connectors, beam bottom brackets and beam segment connectors;

[0006] The beam-binding connector is a steel plate, with one side fixed to the precast beam and the other side fixed to the precast column, used for horizontal connection and fixation between the precast beam and the column. The side of the steel plate is also fixed with a connection end perpendicular to it. The bottom bracket of the beam is a right-angled steel plate, with one right-angled side fixed to the precast column and the other right-angled side parallel to the precast beam, providing vertical support for the precast beam. The beam segment connector is an L-shaped steel plate, with the short side of the L-shape fixed to the connection end of the beam-binding connector and the long side of the L-shape parallel to the precast beam.

[0007] The features of this utility model also include:

[0008] The beam-binding connector includes a square column beam-binding connector for connecting right-angle sections between beams and square columns. The square column beam-binding connector is an L-shaped ribbed steel plate, which is vertically fixed to two rectangular steel plates. Both rectangular steel plates have beam-column fixing bolt holes. Both rectangular steel plates have end fixing steel plates vertically fixed to the top edge along the height direction on the side away from the connection. The end fixing steel plates have beam segment fixing bolt holes. The bottom side of the ribbed steel plate away from the end fixing steel plate has bracket fixing bolt holes.

[0009] The beam-binding connector includes a straight beam-binding connector for connecting the straight sections of beams and columns with different cross-sectional shapes. The straight beam-binding connector is a straight ribbed steel plate. Both sides of the straight ribbed steel plate are provided with beam-column fixing bolt holes. An end fixing steel plate is vertically fixed to the top edge of one side along the height direction. A bracket fixing bolt hole is opened at the bottom of the side of the ribbed steel plate away from the end fixing steel plate.

[0010] The beam-binding connector includes a right-angle beam-binding connector for connecting right-angle segments between beams. The right-angle beam-binding connector is an L-shaped ribbed steel plate, which is made of two identical rectangular steel plates that are vertically fixed together. Both rectangular steel plates have beam-column fixing bolt holes. Both rectangular steel plates have end fixing steel plates that are vertically fixed at the top edge along the height direction on the side away from the connection side. The end fixing steel plates have beam segment fixing bolt holes. The bottom side of the ribbed steel plate away from the end fixing steel plate has bracket fixing bolt holes.

[0011] The beam-binding connector includes a T-shaped column-beam-binding connector for connecting the right-angle section between the beam and the T-shaped column. The T-shaped column-beam-binding connector is an L-shaped ribbed steel plate. The L-shaped ribbed steel plate is vertically fixed by two rectangular steel plates. Each rectangular steel plate has at least one row of beam-column fixing bolt holes on both the side near the connection and the side away from the connection. The top edge of the two rectangular steel plates on the side away from the connection is vertically fixed with an end fixing steel plate. The end fixing steel plate has beam segment fixing bolt holes. The bottom of the side of the ribbed steel plate away from the end fixing steel plate has bracket fixing bolt holes.

[0012] The steel plates on both sides of the beam bottom bracket are respectively provided with precast column fixing bolt holes and precast beam fixing bolt holes. The edges of the right-angled steel plates are fixed with ribs, and one of the ribs on the right-angled side is provided with clamp fixing bolt holes.

[0013] A reinforcing rib is provided on the inner center of the L-shaped steel plate corner structure along the corner direction.

[0014] The beam segment connector is formed by perpendicularly connecting a square web and a rectangular web to form a right angle shape. The square web has holes for beam binding bolts.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model includes multiple functional forms such as beam bottom corbels, beam binding connectors, and beam segment connectors. Combined with an integrated component of the exterior wall composite insulation structure made of ultra-high performance inorganic composite concrete material and an ICM steel truss floor deck, it can eliminate the need for a support system within a maximum span of three meters, further optimizing construction efficiency and quality.

[0017] 2. This utility model can be prefabricated in the factory according to design requirements and is suitable for temporary fixing of various types of prefabricated beams and columns. This design is easy to reuse at different construction sites and greatly reduces construction costs.

[0018] 3. This utility model is applicable to precast beams and columns in assembled structures. By pre-drilling bolt holes on the beams and columns, and creating corresponding mounting holes on the beam-binding connectors and beam bottom brackets, bolts are used to fix the beam-binding connectors and beam bottom brackets to the precast beams and columns. This ensures precise alignment during assembly and achieves rapid temporary fixing. Simultaneously, this utility model can serve as an external formwork for the grouting material at joints, facilitating installation and significantly reducing construction time. By setting end fixing steel plates on the beam-binding connectors to fix the beam segment connectors, the beam segment connectors can support the precast composite floor decking, thereby achieving a floor decking-free support effect.

Figure 7 As shown, channel steel 11 can be placed above the beam segment connector to support the precast composite floor deck, thus achieving the effect of eliminating the need for support on the floor deck.

[0073] The specific implementation process for the aforementioned beam-binding connectors, beam bottom corbels, and beam segment connectors is as follows:

[0074] Step 1: According to the design requirements, prefabricate the square column beam-binding connectors, straight beam-binding connectors, right-angle beam-binding connectors, T-shaped column beam-binding connectors, beam bottom brackets and beam segment connectors in the factory, and reserve bolt holes corresponding to the beam-column fixing bolt holes 2 on the prefabricated beams and prefabricated columns.

[0075] Step 2: After the precast columns are installed, lift the precast composite beams to the designated position and select different types of beam-tying connectors. Taking a square column as an example, first install the bottom bracket of the beam. Align the precast column fixing bolt holes 5 with the reserved bolt holes of the square column, and the precast beam fixing bolt holes 6 with the reserved bolt holes at the bottom of the beam. Then tighten the bolts to fix them. Figure 10 As shown.

[0076] Step 3: Install the straight beam tie-in connector, aligning the beam-column fixing bolt holes 2 on it with the pre-drilled bolt holes on the precast square column 9 and precast beam 8, and tighten the bolts to secure them. Figure 7 As shown;

[0077] Step 4: Install the square column-beam tie-fit connectors, aligning the pre-drilled bolt holes 2 on the connectors with the pre-drilled bolt holes on the precast square column 9 and precast beam 8, and tighten the bolts to secure them. Figure 8 As shown;

[0078] Step 5: Install the beam segment connector, aligning the beam fixing bolt holes 7-a on it with the beam segment fixing bolt holes 1-a on the beam connector, and tighten the bolts to secure it. Then, place the floor deck support platform 11 (channel steel) on top of the beam segment connector, as shown below. Figure 7 As shown;

[0079] Step 6: Use a laser instrument to check for installation errors. After confirming that there are no errors, tighten the bolts, then remove the hoisting machinery and hoist the precast composite floor deck to the corresponding position, where it will be supported by the floor deck support platform.

[0080] Step 7: Grout the beam-column connection joints, such as... Figure 11 As shown, the concrete pouring of the composite beam and precast composite floor slab is then carried out. After the grout and concrete reach the design strength, the clamps of this utility model are removed, and the surface is rinsed and cleaned in preparation for reuse.
