Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete, in particular to a reinforced concrete beam node reinforcement device. Background Art

[0002] The nodes of reinforced concrete frame structures are not only the places where the upper and lower frame columns and frame beams intersect, but also the key points of the seismic fortification of the building structure. Node damage often causes continuous collapse and damage of the entire frame structure, with very serious consequences. Therefore, it is very necessary to take certain reinforcement measures for frame beam-column nodes that have safety hazards.

[0003] As disclosed in publication number CN218715388U, a reinforced concrete frame structure node reinforcement device is proposed, which includes a reinforced concrete beam and a reinforced concrete column. Steel plates are arranged on the lower surface of the reinforced concrete beam and one side of the reinforced concrete column. A reinforcement body for reinforcing the steel plate is arranged on the surface of the steel plate. A stabilizing rod for stabilizing the position of the steel plate is arranged on the surface of the reinforcement body. In the reinforced concrete frame structure node reinforcement device, the reinforcement body is fixedly connected to the steel plate by two steel plates that are arranged vertically and fixedly connected. Then, the stabilizing rod is inserted into both ends of the reinforcement body and the steel plate. Then, the steel plate is rotated and connected to the lower surface of the reinforced concrete beam and one side of the reinforced concrete column. This can achieve the effect of reinforcing the reinforced concrete frame structure node, which is beneficial to strengthening the strength of the node, increasing durability, and also ensuring aging resistance, thereby avoiding the situation where the steel plate is detached due to a long time.

[0004] This device is only applicable to the case where the beams and columns are vertical. In the prior art, if the nodes of beams and columns at angles other than vertical are to be reinforced, it is necessary to prefabricate reinforcement devices according to the angles of the beams and columns. Therefore, a reinforced concrete beam node reinforcement device is proposed to solve the above problem. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a reinforced concrete beam node reinforcement device, which has the advantages of not needing to be prefabricated according to the angles between the beams and the columns, and can be applied to different angles of the beams and the columns. This solves the problem that the device is only applicable to the situation where the beams and the columns are vertical, and in the prior art, if nodes of beams and columns at angles other than the vertical situation are to be reinforced, it is necessary to prefabricate the reinforcement device according to the angles between the beams and the columns.

[0007] (II) Technical solution

[0008] The utility model solves the above-mentioned technical problems through the following technical solutions: A reinforced concrete beam node reinforcement device, comprising a concrete column, a concrete beam and a first connecting steel plate, the right side of the concrete column is fixedly connected with a first connecting steel plate in contact with the bottom of the concrete beam, the inside of the first connecting steel plate is fixedly connected with a hinge rod near the top thereof, the outer side of the hinge rod is rotatably connected with a second connecting steel plate fixedly connected to the bottom of the concrete beam, the outer side of the hinge rod is provided with an adjustment component rotatably connected thereto, the right side of the first connecting steel plate and the bottom of the second connecting steel plate are both fixedly connected with mutually adaptable hinge seats, the outer side of the adjustment component is provided with a support component threadedly connected thereto and hinged to the hinge seat, the outer side of the adjustment component is provided with a anti-loosening nut tightly fitting with the right side of the support component.

[0009] The beneficial effect of the utility model is that when the device is installed, the top of the first connecting steel plate is against the bottom of the concrete beam and fixed to the right side of the concrete column, and the support component is driven to move by rotating the adjustment component. At the same time, the adjustment component rotates around the hinge rod until the support component drives the top of the second connecting steel plate to fit tightly with the bottom of the concrete beam, thereby rotating the anti-loosening nut to make it fit tightly with the right side of the support component, and finally the second connecting steel plate is fixedly connected to the concrete beam, and the first connecting steel plate and the second connecting steel plate are fixed at the node between the concrete column and the concrete beam. The support component and the adjustment component can be regarded as a support frame, which supports the first connecting steel plate and the second connecting steel plate, that is, strengthens and fixes the node between the concrete column and the concrete beam.

[0010] The reinforced concrete beam node reinforcement device has the advantages of not needing to be prefabricated according to the angles of the beams and the columns and being applicable to different angles of the beams and the columns.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the surfaces of the first connecting steel plate and the second connecting steel plate are both provided with through holes distributed in four corners.

[0013] The beneficial effect of adopting the above further scheme is that when the device is installed, the top of the first connecting steel plate is placed against the bottom of the concrete beam, and then the fixing bolts are passed through the through holes to fix the first connecting steel plate and the concrete column with the fixing bolts, and the second connecting steel plate and the concrete beam are fixedly connected, which is also the above fixing method.

[0014] Further, the adjustment assembly includes a rotating seat and an adjusting threaded rod, the outer side of the hinged rod is rotatably connected to the rotating seat, and the right side of the rotating seat is rotatably connected to the adjusting threaded rod;

[0015] Furthermore, the support assembly includes an internally threaded hinge ring and a support rod, the outer side of the adjusting threaded rod is threadedly connected to the internally threaded hinge ring, and the outer side of the internally threaded hinge ring is hinged to support rods that are symmetrically distributed and hinged to adjacent hinge seats.

[0016] The beneficial effect of adopting the above further scheme is that by rotating the adjusting threaded rod, the force generated by the rotation of the thread drives the internal threaded hinge ring along the adjusting threaded rod to approach the hinge rod, and then causes the support rod to rotate toward the opposite side around the hinge between it and the internal threaded hinge ring. At the same time, the rotating seat rotates upward around the hinge rod, thereby driving the second connecting steel plate to rotate upward around the hinge rod until the top of the second connecting steel plate is tightly fitted with the bottom of the concrete beam.

[0017] Furthermore, the outer side of the adjusting threaded rod is threadedly connected with a locking nut which is tightly fitted with the right side of the internal threaded hinge ring.

[0018] The beneficial effect of adopting the above further scheme is that when the top of the second connecting steel plate is tightly fitted with the bottom of the concrete beam, the anti-loosening nut can be rotated to make it tightly fit with the right side of the internal threaded hinge ring, so that the internal threaded hinge ring can be prevented from loosening.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-2A reinforced concrete beam node reinforcement device is provided. The utility model comprises a concrete column 1, a concrete beam 2 and a first connecting steel plate 3. The right side of the concrete column 1 is fixedly connected with a first connecting steel plate 3 in contact with the bottom of the concrete beam 2. The first connecting steel plate 3 is fixedly connected with a hinge rod 4 near the top thereof inside. The outer side of the hinge rod 4 is rotatably connected with a second connecting steel plate 5 fixedly connected with the bottom of the concrete beam 2. An adjusting component 6 rotatably connected thereto is provided on the outer side of the hinge rod 4. The right side of the first connecting steel plate 3 and the bottom of the second connecting steel plate 5 are both fixedly connected with mutually adapted hinge seats 7. The outer side of the adjusting component 6 is provided with a supporting component 8 threadedly connected thereto and hinged to the hinge seat 7. The outer side of the adjusting component 6 is provided with a locking nut 9 tightly fitted with the right side of the supporting component 8.

[0024] The surfaces of the first connecting steel plate 3 and the second connecting steel plate 5 are both provided with through holes 10 distributed in four corners;

[0025] When installing the device, the top of the first connecting steel plate 3 is placed against the bottom of the concrete beam 2, and then the fixing bolts are passed through the through holes 10, and the first connecting steel plate 3 is fixedly connected to the concrete column 1 by the fixing bolts, and the second connecting steel plate 5 is fixedly connected to the concrete beam 2, which is also the above fixing method;

[0026] The adjustment assembly 6 includes a rotating seat 601 and an adjusting threaded rod 602. The outer side of the hinge rod 4 is rotatably connected to the rotating seat 601, and the right side of the rotating seat 601 is rotatably connected to the adjusting threaded rod 602.

[0027] The support assembly 8 includes an internal thread hinge ring 801 and a support rod 802. The outer side of the adjusting threaded rod 602 is threadedly connected to the internal thread hinge ring 801. The outer side of the internal thread hinge ring 801 is hinged to a support rod 802 that is symmetrically distributed and hinged to the adjacent hinge seat 7.

[0028] By rotating the adjusting threaded rod 602, the force generated by the rotation of the thread drives the internal threaded hinge ring 801 to approach the hinge rod 4 along the adjusting threaded rod 602, and then the support rod 802 rotates to the opposite side around the hinge between it and the internal threaded hinge ring 801. At the same time, the rotating seat 601 rotates upward around the hinge rod 4, thereby driving the second connecting steel plate 5 to rotate upward around the hinge rod 4 until the top of the second connecting steel plate 5 is tightly fitted with the bottom of the concrete beam 2.

[0029] The outer side of the adjusting threaded rod 602 is threadedly connected with a locking nut 9 which is tightly fitted to the right side of the internal threaded hinge ring 801;

[0030] When the top of the second connecting steel plate 5 is tightly fitted with the bottom of the concrete beam 2, the anti-loosening nut 9 is rotated to make it tightly fit with the right side of the internal thread hinge ring 801, so that the internal thread hinge ring 801 can be prevented from loosening.

[0031] Working principle:

[0032] Step 1: When installing the device, the top of the first connecting steel plate 3 is placed against the bottom of the concrete beam 2, and then the fixing bolts are passed through the through holes 10 to fix the first connecting steel plate 3 and the concrete column 1 together through the fixing bolts;

[0033] Step 2: By rotating the adjusting threaded rod 602, the force generated by the rotation of the thread drives the internal threaded hinge ring 801 to approach the hinge rod 4 along the adjusting threaded rod 602, and then the support rod 802 rotates to the opposite side around the hinge between it and the internal threaded hinge ring 801. At the same time, the rotating seat 601 rotates upward around the hinge rod 4, thereby driving the second connecting steel plate 5 to rotate upward around the hinge rod 4 until the top of the second connecting steel plate 5 is tightly fitted with the bottom of the concrete beam 2.

[0034] Step 3: When the top of the second connecting steel plate 5 is tightly fitted with the bottom of the concrete beam 2, the anti-loosening nut 9 is turned to make it tightly fit with the right side of the internal threaded hinge ring 801, so that the internal threaded hinge ring 801 can be prevented from loosening. Finally, the fixing bolt is passed through the through hole 10 to fix the second connecting steel plate 5 and the concrete beam 2 with the fixing bolt.
