Description

Technical Field

[0001] The utility model relates to the technical field of steel structure installation, in particular to a unidirectional connection node of a steel member with multiple reinforcements. Background Technique

[0002] In a steel structure, the connection between the steel structure and a concrete pier usually adopts three forms: flexible connection (also called hinge connection), rigid connection, and variable stiffness connection. Among them, the rigid connection means no rotation at all, the flexible connection (hinge connection) means free rotation, and the variable stiffness connection is a connection form between the flexible connection and the rigid connection.

[0003] In the connection of a steel frame, especially the installation of an I-shaped steel frame, since the cross-section is I-shaped, contact connectors are required for installation with a wall. Currently, most connections are fixed by bolts combined with welding. On the one hand, the contact area between the I-shaped steel frame and the connector is small, and at the same time, the support for the I-shaped steel frame is insufficient. For this reason, we designed a unidirectional connection node of a steel member with multiple reinforcements. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a unidirectional connection node of a steel member with multiple reinforcements.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A unidirectional connection node of a steel member with multiple reinforcements, including a mounting plate, two detachable L-shaped reinforcing plates are installed on the outer wall of the mounting plate, limit plates are fixed at the top and bottom of the mounting plate where the L-shaped reinforcing plates are located, and two symmetrical force-bearing frames are fixed on the limit plates;

[0007] One side of the force-bearing frame close to the mounting plate is fixed to the mounting plate. A cavity is provided inside the force-bearing frame, a T-shaped plate is embedded in the force-bearing frame, and a slot is opened in the middle of the T-shaped plate.

[0008] As a further scheme of the utility model, a number of equally spaced second mounting holes are evenly opened on the side of the L-shaped reinforcing plate that fits the mounting plate, and first mounting holes adapted to the second mounting holes are opened on the mounting plate.

[0009] As a further scheme of the utility model, a number of third mounting holes are evenly opened on the side of the L-shaped reinforcing plate away from the mounting plate.

[0010] As a further scheme of the utility model, fourth mounting holes are opened on the force-bearing frame, fifth mounting holes are opened at positions corresponding to the fourth mounting holes on the T-shaped plate, and the T-shaped plate and the force-bearing frame are fixed by third bolts.

[0011] As a further solution of the present utility model, the L-shaped reinforcing plate and the mounting plate are fixed by a first bolt, and the first bolt is a chemical bolt. The L-shaped reinforcing plate increases the contact area with the mounting plate and enhances stability.

[0012] As a further solution of the present utility model, the two L-shaped reinforcing plates and the I-shaped steel frame are fixed by a second bolt.

[0013] As a further solution of the present utility model, a side stress plate is fixed on the outer wall of the L-shaped reinforcing plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the present utility model: Since the designed limit plate abuts against the upper and lower parts of the I-shaped steel frame, at the same time, the provided stress frame and side stress plate strengthen its stability. Take out the provided T-shaped plate, insert it onto two corresponding stress frames, and fix it with a third bolt, effectively solving the problems raised in the background technology. Furthermore, it realizes strengthening the tensile resistance between the two mounting plates, and it is detachable and replaceable to keep it in the best working state. It increases the contact area between the L-shaped reinforcing plate and the mounting plate, increases the contact area with the I-shaped steel frame, and adds multiple support points. Through the above design, the connection strength between the I-shaped steel frame and the connection node is effectively enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] Referring to Figures 1-4 , a unidirectional connection node of a multi-reinforced steel member, including a mounting plate 1, two detachable L-shaped reinforcing plates 2 are installed on the outer wall of the mounting plate 1, and limiting plates 3 are fixed at both the top and bottom of the mounting plate 1 where the L-shaped reinforcing plates 2 are located, and two symmetric force-bearing frames 7 are fixed on the limiting plates 3;

[0024] One side of the force-bearing frame 7 close to the mounting plate 1 is fixed to the mounting plate 1. A cavity is provided inside the force-bearing frame 7, and a T-shaped plate 9 is fitted inside the force-bearing frame 7. A slot 10 is provided in the middle of the T-shaped plate 9.

[0025] In this embodiment, a number of equally spaced second mounting holes 201 are evenly provided on the side of the L-shaped reinforcing plate 2 that fits the mounting plate 1, and first mounting holes 101 adapted to the second mounting holes 201 are provided on the mounting plate 1.

[0026] In this embodiment, a number of third mounting holes 202 are evenly provided on the side of the L-shaped reinforcing plate 2 away from the mounting plate 1.

[0027] In this embodiment, a fourth mounting hole 8 is provided on the force-bearing frame 7, and a fifth mounting hole 11 is provided at the position corresponding to the fourth mounting hole 8 on the T-shaped plate 9. The T-shaped plate 9 and the force-bearing frame 7 are fixed by a third bolt.

[0028] In this embodiment, the L-shaped reinforcing plate 2 and the mounting plate 1 are fixed by a first bolt 4, and the first bolt 4 is a chemical bolt. The L-shaped reinforcing plate 2 increases the contact area with the mounting plate 1 and enhances stability.

[0029] In this embodiment, the two L-shaped reinforcing plates 2 and the I-shaped steel frame are fixed by a second bolt 5.

[0030] In this embodiment, a side force-bearing plate 6 is fixed on the outer wall of the L-shaped reinforcing plate 2.

[0031] Working principle: When in use, if the I-shaped steel frame is installed on the wall column, first make a hole in the wall in advance, then inject chemical agents, and then insert the first bolt 4 into the agents. The bolt is bitten by the pre-tightening force generated by the agents. At this time, the mounting plate 1 and the L-shaped reinforcing plate 2 are fixed on the wall. Then, the I-shaped steel frame is installed on the mounting plate 1 and fixed by passing the first bolt 4 through the holes opened on the I-shaped steel frame. If two I-shaped steel frames are installed, at this time, two sets of mounting plates 1 are required. Fix the two mounting plates 1, and then fix the I-shaped steel frames to the mounting plates 1 one by one. The set limit plate 3 abuts against the upper and lower parts of the I-shaped steel frame. At the same time, the set stress-bearing frame 7 and the side stress-bearing plate 6 enhance its stability. Take out the set T-shaped plate 9 and insert it onto two corresponding stress-bearing frames 7 and fix it with the third bolt to enhance the tensile resistance between the two mounting plates 1 and increase the contact area between the L-shaped reinforcing plate 2 and the mounting plate 1. Through the above design, the connection strength between the I-shaped steel frame and the connection node is effectively enhanced.
