Description

Technical Field

[0001] This utility model relates to the field of building reinforcement components, and in particular to a steel sleeve reinforcement component for building frame structure nodes. Background Technology

[0002] Beam-column joints mainly refer to the areas where beam and column components overlap. They are the joint areas where beams and columns meet. In seismic design, there are special provisions and limits on the shear bearing capacity of the core area of ​​the joint to ensure the reliability of the joint. The beams and columns are connected by clamps.

[0003] In existing technologies, traditional steel hoop reinforcement uses steel plates to wrap the node area and forms a constraint system through bolts or welding. Although it can provide a certain circumferential constraint force, when the steel plate is not tightly attached to the concrete surface, slippage is likely to occur, resulting in a reduction in the constraint effect and a risk of interfacial bonding failure. Utility Model Content

[0004] This utility model mainly provides a steel hoop reinforcement component for building frame structure nodes that can easily fit tightly to the concrete surface of the node area to prevent slippage and ensure the constraint effect of this utility model on the node area.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel sleeve reinforcement component for a building frame structure node, comprising a clamping plate one, a clamping plate two installed on the end face of the clamping plate one, grouting grooves being formed on the inner sidewalls of both the clamping plate one and the clamping plate two, corrugated steel plates being fixedly connected to the inner wall of the grouting grooves, grouting holes being formed through the top surfaces of both the clamping plate one and the clamping plate two, the interior of the grouting holes communicating with the interior of the grouting grooves, and a connecting groove being formed through the outer wall of the corrugated steel plates.

[0006] Preferably, a bolt is connected through the outer wall of the first clamping plate, and one end of the bolt is threaded through the outer wall of the second clamping plate and connected to a nut. The connection between the first clamping plate and the second clamping plate is fixedly installed by using the connection of the bolt and the nut.

[0007] Preferably, side connecting plates are fixedly connected to both outer walls of the second clamping plate. The side connecting plates facilitate the connection and installation position of the lateral auxiliary structure provided by this utility model.

[0008] Preferably, the end face of the second clamping plate is provided with a slot, and a positioning plate is inserted into the inner wall of the slot. The insertion of the positioning plate into the slot enables the first clamping plate and the second clamping plate to be quickly positioned and connected, thereby improving the installation efficiency of this utility model.

[0009] Preferably, one end of the positioning insert is fixedly connected to the end face of the first clamping plate, so that the first clamping plate and the second clamping plate maintain a stable connection.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, after clamping and installing clamping plate one and clamping plate two from both sides of the beam-column joint, high-strength non-shrink grout is injected into the grouting grooves of clamping plate one and clamping plate two through grouting holes to fill the gaps. With the setting of the connecting groove, the grout flows better to fill the gaps, so that clamping plate one and clamping plate two are tightly attached to the concrete surface of the joint area to prevent slippage and ensure the constraint effect of this utility model on the joint area.

[0012] 2. In this utility model, the composite structure formed by the corrugated steel plate and the high-strength grouting material enhances the shear stiffness of the utility model and improves the shear bearing capacity of the joint. The corrugated steel plate's curved surface structure generates out-of-plane buckling plastic deformation under horizontal load, allowing the joint to consume more energy under cyclic loads and reducing damage to the main structure. The insertion of the positioning plate and the slot enables quick positioning and connection between the clamping plate one and the clamping plate two, improving the installation efficiency of this utility model.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a steel sleeve reinforcement component for a building frame structure node, including a clamping plate 1, a clamping plate 2 installed on the end face of clamping plate 1, grouting grooves 5 are formed on the inner sidewalls of clamping plate 1 and clamping plate 2, corrugated steel plates 51 are fixedly connected to the inner wall of the grouting grooves 5, grouting holes 7 are formed through the top surface of clamping plate 1 and clamping plate 2, the interior of the grouting holes 7 is connected to the interior of the grouting grooves 5, and a connecting groove 52 is formed through the outer wall of the corrugated steel plate 51, through which grout is injected into clamping plate 1 and clamping plate 2 through the grouting holes 7. High-strength, non-shrink grout is injected into the groove 5 to fill the gaps, so that the clamping plates 1 and 2 are tightly bonded to the concrete surface. The composite structure formed by the corrugated steel plate 51 and the high-strength grout enhances the shear stiffness of this invention. The corrugated steel plate 51 generates out-of-plane buckling plastic deformation under horizontal loads by utilizing its corrugated surface structure, which allows the joint to consume more energy in seismic cyclic loads, reducing damage to the main structure. The uniformity of triaxial compressive stress distribution in the concrete of the joint area is effectively improved, avoiding the stress concentration problem at the beam-column junction caused by traditional flat plate hoops.

[0021] like Figure 1 As shown, a bolt 3 is connected through the outer wall of clamp 1, and a nut 4 is threaded through the outer wall of clamp 2. The clamp 1 and clamp 2 are fixedly installed by using the connection of bolt 3 and nut 4.

[0022] like Figure 1 As shown, side connecting plates 6 are fixedly connected to both outer walls of the second clamp 2. The side connecting plates 6 facilitate the connection and installation position of the lateral auxiliary structure provided by this utility model.

[0023] like Figure 4 As shown, a slot 21 is provided on the end face of the second clamp 2, and a positioning plate 11 is inserted into the inner wall of the slot 21. The insertion of the positioning plate 11 into the slot 21 enables the first clamp 1 and the second clamp 2 to be quickly positioned and connected, thereby improving the installation efficiency of this utility model.

[0024] like Figure 4 As shown, one end of the positioning plate 11 is fixedly connected to the end face of the clamping plate 1, so that the clamping plate 1 and the clamping plate 2 maintain a stable connection.

[0025] The usage method and working principle of this device are as follows: When in use, the user clamps clamp 1 and clamp 2 from both sides of the beam-column joint. The clamp 1 and clamp 2 are quickly positioned and connected by inserting the positioning plate 11 into the slot 21. The connection end faces of clamp 1 and clamp 2 are fixed and installed by bolts 3 and nuts 4. After the connection is fixed, high-strength non-shrink grout is injected into the grouting grooves 5 of clamp 1 and clamp 2 through the grouting hole 7 to fill the gaps, so that clamp 1 and clamp 2 are tightly attached to the concrete surface. The composite structure formed by the corrugated steel plate 51 and the high-strength grout increases the shear stiffness of this utility model. The corrugated steel plate 51 generates out-of-plane buckling plastic deformation under horizontal load by utilizing the corrugated curved surface structure.
