Description

Technical Field

[0001] This utility model relates to the field of node reinforcement technology, and in particular to a node reinforcement structure for multi-directional steel-supported concrete frames. Background Technology

[0002] Multi-directional steel-braced concrete frame joint reinforcement is a design measure aimed at improving the seismic performance, load-bearing capacity, and stability of building structures. It mainly involves adding steel supports in multiple directions at key joints of the concrete frame to enhance the stiffness and strength of the joints, thereby optimizing the performance of the entire frame structure.

[0003] Currently, existing multi-directional steel-braced concrete frame joint reinforcement structures cannot form a multi-dimensional reinforcement system in the concrete frame, resulting in buildings not being able to maintain better stability and safety when faced with external forces such as wind loads and earthquakes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot form a multi-dimensional reinforcement system in concrete frames, resulting in buildings not being able to maintain better stability and safety when faced with external forces such as wind loads and earthquakes. The invention proposes a multi-directional steel-braced concrete frame node reinforcement structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Multi-directional steel-braced concrete frame joint reinforcement construction includes:

[0007] The column and the beam are provided in four parts, and the four columns and four beams form a concrete frame.

[0008] The first reinforcing component is disposed at the node between the column and the beam and is used to reinforce the node between the two.

[0009] The second reinforcing component is disposed on the crossbeam and is used to enhance the strength and stiffness between the crossbeams.

[0010] In one possible design, the first reinforcing component includes four node fixing plates that are detachably installed at four nodes inside the concrete frame consisting of four columns and four beams. A first steel beam is fixedly installed between the node fixing plates on two symmetrical sides, and a second steel beam is fixedly installed on each of the other two symmetrical node fixing plates.

[0011] In one possible design, the second reinforcing component includes two connecting frames fixedly mounted on one end of two No. 2 steel beams, with reinforcing rods hinged to both ends of the two connecting frames. Each of the four crossbeams has a fixing seat detachably fixed on one side of its inner wall. The two reinforcing rods located on the same connecting frame are hinged to two adjacent fixing seats.

[0012] In one possible design, bolt rods are fixedly installed on the adjacent sides of the two connecting frames. The two bolt rods are arranged alternately vertically. Two through holes are opened alternately vertically on one side of the No. 1 steel beam. The two bolt rods can be detached and inserted into the two through holes respectively. A locking nut is threaded to one end of each bolt rod.

[0013] In one possible design, both the No. 1 and No. 2 steel beams are H-beams.

[0014] In one possible design, the connecting frame and the fixed seat are connected to the reinforcing rod by a pin, and the pin on the connecting frame and the fixed seat is detachable.

[0015] In this application, when it is first used, the required materials that meet the design requirements are prepared. Then the design drawings are reviewed to ensure that all dimensions, materials and installation requirements are accurate. Then the construction site is inspected to ensure that the foundation conditions meet the installation requirements, including flatness, load-bearing capacity, etc.

[0016] Following the design drawings, four columns and four beams were poured to form a concrete frame. Once the pouring was complete and construction was ready, node fixing plates were installed at each column-beam joint. These plates were then securely connected to the inside of the concrete frame using bolts or other fasteners. Next, a first steel beam was installed between the two symmetrical node fixing plates, ensuring its accurate positioning. It was then firmly connected to the node fixing plates using welding or other fixing methods. Second steel beams were then installed on the other two symmetrical node fixing plates, again ensuring their accurate positioning and secure fixing. Finally, connecting brackets were installed at the adjacent ends of the two second steel beams, ensuring their correct positioning and securing them to the second steel beams using welding or other fixing methods. Next, at both ends of the connecting frame, use pins to connect the reinforcing rods to the connecting frame, ensuring that the pins are detachable for subsequent adjustment or disassembly. Then, install fixing seats on one side of the inner wall of the four crossbeams, and use bolts or other fasteners to tightly connect the fixing seats to the crossbeams. Then, connect the two reinforcing rods on the same connecting frame to the two adjacent fixing seats with pins to complete the installation of the reinforcing rods. Then, fix bolt rods on the side of the two connecting frames that are close to each other, ensuring that the bolt rods are staggered vertically to align with the through holes on the No. 1 steel beam. Pass the bolt rods through the through holes on the No. 1 steel beam, and install lock nuts on the other end of the bolt rods. By tightening the lock nuts, the connecting frame, the No. 1 steel beam, and the No. 2 steel beam are firmly connected together, completing the overall structural reinforcement of the concrete frame.

[0017] A comprehensive inspection of the entire multi-directional steel-supported concrete frame was then conducted to ensure that all components were installed correctly, fasteners were secure, and connections were free of cracks or defects. Necessary functional tests, such as load tests, were performed to verify that the load-bearing capacity and stability of the reinforced structure met the design requirements.

[0018] This utility model has the following beneficial effects:

[0019] In this utility model, by setting the first reinforcing component, that is, installing a node fixing plate at the node between the column and the beam, and fixing the No. 1 steel beam and the No. 2 steel beam to connect them, the load-bearing capacity and stability at the node are enhanced, effectively preventing the structure from deforming or being damaged when under stress, thereby improving the safety and durability of the entire concrete frame.

[0020] In this utility model, the setting of the second reinforcing component, namely the installation of a fixing seat on the inner wall of the crossbeam and the hinge connection with the connecting frame and the reinforcing rod, effectively enhances the strength and rigidity between the crossbeams, improves the overall lateral stability and anti-lateral displacement capacity of the concrete frame, and further enhances the overall load-bearing capacity and seismic performance of the structure.

[0021] This invention, through the coordinated arrangement of the first and second reinforcing components, forms a multi-dimensional reinforcement system in the concrete frame, which not only improves the safety and durability of the entire concrete frame, but also enhances the overall load-bearing capacity and seismic performance of the structure, enabling the building to maintain better stability and safety when facing external forces such as wind loads and earthquakes.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] Reference Figure 1-4 Node enhancement construction includes:

[0030] The four columns 1 and four beams 2 are all precast or cast-in-place concrete components. They are poured according to the design drawings to form a concrete frame, ensuring that the connection between the columns 1 and the beams 2 is accurate and laying the foundation for subsequent reinforcement work.

[0031] At each node between column 1 and beam 2, a node fixing plate 3 is installed. The node fixing plate 3 is tightly connected to the node on the inner side of the concrete frame formed by column 1 and beam 2 by bolts or other fastening devices to ensure stability and reliability. A first steel beam 4 is installed between the two symmetrical node fixing plates 3 to ensure that it can span and reinforce the two opposite nodes. On the other two symmetrical node fixing plates 3, a second steel beam 5 is installed respectively, thereby enhancing the load-bearing capacity and stability at the node and effectively preventing the structure from deforming or breaking under stress, thus improving the safety and durability of the entire concrete frame. Both the first steel beam 4 and the second steel beam 5 are H-beams, and their dimensions and installation positions must conform to the design drawings.

[0032] At the two adjacent ends of the No. 2 steel beams 5, connecting frames 6 are installed respectively. The connecting frames 6 are tightly connected to the No. 2 steel beams 5 by welding or other fixing methods to ensure their stability and load-bearing capacity. At both ends of each connecting frame 6, reinforcing rods 7 are hinged. The reinforcing rods 7 are connected to the connecting frame 6 by pins. The pins are detachable for easy installation and adjustment. The other end of the reinforcing rod 7 is hinged to the fixing seat 8 on one side of the inner wall of the adjacent crossbeam 2. Similarly, the fixing seat 8 is also tightly connected to the inner wall of the crossbeam 2 by bolts or other fastening devices. This effectively enhances the strength and rigidity between the crossbeams 2, improves the overall lateral stability and anti-lateral displacement capacity of the concrete frame, and further enhances the overall load-bearing capacity and seismic performance of the structure.

[0033] On the side of the two connecting frames 6 that are close to each other, bolt rods 9 are fixedly installed. The bolt rods are arranged in an alternating manner to ensure alignment with the through holes 11 on the No. 1 steel beam 4.
