Description

Technical Field

[0001] The utility model relates to the technical field of building structure reinforcement devices, in particular to a building steel beam connection reinforcement device. Background Art

[0002] like Figure 1 、 2 As shown, when conventional vertical steel columns are fixed to steel beams, a general method is to weld a welding collar on the side of the steel column, and then use the welding collar as a support and connector to fix the steel columns to multiple horizontally arranged steel beams. In this way, if reinforcement is required later, a more common method is to weld a support frame between the steel beam and the steel column. However, this method cannot form a high reinforcement effect on the connection position of the steel column and the steel beam. Utility Model Content

[0003] In order to solve the problem that the conventional support frame has poor reinforcement effect on steel columns and steel beams, the utility model provides a construction steel beam connection reinforcement device.

[0004] The technical solution of this utility model is as follows:

[0005] A building steel beam connection reinforcement device is provided at the connection structure between a steel column and a steel beam, comprising a plurality of arc-shaped reinforcement plates arranged circumferentially around the steel column, wherein the plurality of arc-shaped reinforcement plates are detachably connected to each other, and each arc-shaped reinforcement plate is fixedly connected to the steel column;

[0006] A connecting reinforcing plate is provided on one side of the arc-shaped reinforcing plate close to the steel beam, and a plurality of reinforcing rods are provided on the connecting reinforcing plate at positions corresponding to the steel beam to penetrate and be fixedly connected to the steel beam;

[0007] Reinforcing ribs are provided between the arc-shaped reinforcing plate and the connecting reinforcing plate and are integrally formed.

[0008] By arranging an arc-shaped reinforcement plate to connect with the steel column, the connection reinforcement plate formed integrally therewith can form a supporting structure, and then it only needs to be connected to the steel beam to obtain a better reinforcement effect.

[0009] The arc-shaped reinforcement plate is connected to the steel column by providing the arc-shaped reinforcement plate with a plurality of welding holes, and the arc-shaped reinforcement plate is welded to the steel column at the welding holes. Welding is more stable than pressure-locking sleeve connection.

[0010] To improve the connection strength, two curved reinforcement plates are arranged around the steel column, and a connecting portion is provided at the adjacent ends of the two curved reinforcement plates. Bolts are installed through the connecting portion to connect the two curved reinforcement plates. The detachable connection structure is minimized as much as possible, and the structural volume of the integrated structure is increased for connection.

[0011] The above-mentioned welding holes are arranged in a manner that the welding holes are vertically arranged waist-shaped holes. The arrangement of waist-shaped holes can increase the welding area.

[0012] In order to improve the welding strength, the welding holes are arranged in a plurality of non-adjacent directions around the central axis of the cylinder.

[0013] The specific structure of the above-mentioned reinforcement rod is that the reinforcement rod is a bolt rod, one end of which is an enlarged end, and the other end is provided with a nut.

[0014] As a preferred solution, the same connecting reinforcement plate can and can only be fixedly connected to two steel beams at the same time, and the connecting reinforcement plate is arranged horizontally and the reinforcement rod is arranged vertically.

[0015] In order to ensure the connection strength, a reinforcement sleeve is sleeved on the reinforcement rod between the connection reinforcement plate and the steel beam, and the spacing of the reinforcement sleeves is the same as the vertical spacing between the connection reinforcement plate and the steel beam.

[0016] As a preferred solution, the arc-shaped reinforcement plates, connecting reinforcement plates, reinforcement ribs and reinforcement rods are arranged in two groups on the upper and lower sides of the steel beam. The upper and lower distribution arrangement achieves a better reinforcement effect compared to the conventional unilateral arrangement.

[0017] The beneficial effect of the present invention is that the present invention is a construction steel beam connection and reinforcement device, which is different from the existing welding support frame reinforcement method. The present invention is fixedly connected to the steel column by welding an arc-shaped reinforcement plate, and then a connecting reinforcement plate is arranged under the arc-shaped reinforcement plate to serve as a reinforcement platform. After that, it is only necessary to connect the steel beam and the connecting reinforcement plate by using the reinforcement plate to achieve the reinforcement of the connection structure with the steel column. Compared with the conventional support rod method, this method is more stable, and the reinforcement position is located at the connection position. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] 1. Steel column; 2. Welding collar; 3. Steel beam; 4. Arc-shaped reinforcement plate; 41. Connection part; 42. Welding hole; 5. Connecting reinforcement plate; 6. Reinforcement rib; 7. Reinforcement rod; 8. Reinforcement sleeve. DETAILED DESCRIPTION

[0028] like Figure 3-5 The structure steel beam connection reinforcement device shown is arranged as follows Figure 1 、 2 The connection structure of the steel column 1 and the steel beam 3 shown in the figure is different from the conventional method of welding a support frame between the steel column 1 and the steel beam 3. It can make the connection between the steel column 1 and the steel beam 3 more stable, and the direction includes multiple directions of vertical and horizontal, and no longer only provides support in the vertical direction. For this reason, Figure 5 As shown, it includes multiple arc-shaped reinforcement plates 4 arranged circumferentially around the steel column 1. First, the inner arc surface of the arc-shaped reinforcement plate 4 needs to be adapted to the steel column 1 and fit together to ensure that the subsequent connection is more stable. Afterwards, the multiple arc-shaped reinforcement plates 4 can be detachably connected. The purpose of choosing this connection method is to be able to cooperate to achieve a combination such as Figure 3 The clamping steel column 1 shown in the figure may not be able to be installed from the top by means of socketing after the steel column 1 is fixed. Therefore, this detachable connection method is most suitable for the installation of structural parts and is not affected by other structures. It should be noted that each arc-shaped reinforcement plate 4 is fixedly connected to the steel column 1.

[0029] And as Figure 4 As shown, the arc-shaped reinforcement plate 4 is connected to the steel column 1 by providing a plurality of welding holes 42 on the arc-shaped reinforcement plate 4, and the arc-shaped reinforcement plate 4 is welded to the steel column 1 at the welding holes 42. Welding is more stable than pressure-locked sleeve connection, and welding does not cause problems similar to rotation, ensuring a fixing effect close to that of an integrally formed steel column 1.

[0030] The welding holes 42 are arranged in a manner such that they are vertically disposed waist-shaped holes. The waist-shaped holes can increase the welding area, and the waist-shaped holes can be arranged in a non-vertical direction, either tilted or horizontally. However, depending on the requirements, if the longitudinal pressure is high, a vertical setting is required. If the lateral pressure is high, a horizontal setting is required. A specific choice needs to be made based on on-site requirements. In the above structure, in order to improve welding strength, the welding holes 42 are arranged in a plurality of non-adjacent circumferential directions around the central axis of the cylinder. If the welding holes 42 are arranged horizontally, multiple holes need to be arranged at different height planes to ensure a better fixing effect.

[0031] After completing the above structure settings, if Figure 4 As shown, a connecting reinforcement plate 5 is provided on the side of the arc-shaped reinforcement plate 4 close to the steel beam 3. The connecting reinforcement plate 5 needs to be connected to the steel beam 3, and a plurality of reinforcement rods 7 are provided at positions corresponding to the steel beam 3 to penetrate and be fixedly connected to the steel beam 3. In this way, the combined reinforcement of the above-mentioned multiple structural members can be achieved, further ensuring the stability of the steel column 1 and the steel beam 3. It should be noted that, for structural strength considerations, reinforcing ribs 6 are provided between the arc-shaped reinforcement plate 4 and the connecting reinforcement plate 5 and are integrally formed, thereby being able to withstand stronger pressure.

[0032] like Figure 4 As shown, the specific structure of the above-mentioned reinforcement rod 7 is that the reinforcement rod 7 is a bolt rod, and one end is an enlarged end, and a nut is provided at the other end. After the reinforcement rod 7 passes through the two structures, it is locked by the nut to achieve mutual fixation of the two.

[0033] Furthermore, based on the above structure, in order to ensure the connection strength, the reinforcement rod 7 between the connecting reinforcement plate 5 and the steel beam 3 is sleeved with a reinforcement sleeve 8, and the spacing of the reinforcement sleeve 8 is the same as the vertical spacing between the connecting reinforcement plate 5 and the steel beam 3. In this way, the spacing between the two can be ensured to be constant, and after the bolt rod is tightened, the fixing effect is better.

[0034] In order to avoid the above reinforcement process being complicated and the structure being weak, in order to improve the connection strength, such as Figure 3 As shown, two curved reinforcement plates 4 are arranged around the steel column 1. Two is the minimum number that can be used and ensures that the two curved reinforcement plates 4 can each fix two or more steel beams 3. To facilitate installation, connecting portions 41 are provided at adjacent ends of the two curved reinforcement plates 4. Bolts are provided through the connecting portions 41 to connect the two curved reinforcement plates 4. The purpose is to minimize the number of detachable connection structures and increase the structural volume of the integrated structure for connection.

[0035] Afterwards, it should be noted that the same connecting reinforcement plate 5 can and can only be fixedly connected to two steel beams 3 at the same time, and the connecting reinforcement plate 5 is set horizontally and the reinforcement rod 7 is set vertically. Figure 4 The structure shown,

[0036] The above structure can achieve this by setting up an arc-shaped reinforcement plate 4 to connect with the steel column 1, so that the connecting reinforcement plate 5 integrally formed therewith can form a supporting structure. After that, it only needs to be connected to the steel beam 3 to obtain a better reinforcement effect.

[0037] As a preferred embodiment, the arc-shaped reinforcement plate 4, the connecting reinforcement plate 5, the reinforcement rib 6 and the reinforcement rod 7 are arranged in two groups on the upper and lower sides of the steel beam 3. By distributing the upper and lower parts, the reinforcement effect is better than the conventional unilateral arrangement. Figure 6 As shown, the complexity of the reinforcement work has doubled, but the corresponding reinforcement effect will be significantly improved, and it is necessary to make a choice based on the needs.
