Description

Technical Field

[0001] This utility model belongs to the field of steel structure reinforcement technology, and in particular relates to a composite reinforcement connection component for steel structures and concrete beams. Background Technology

[0002] Anchor bolts are pre-embedded in the concrete beam, and steel structural members are fitted onto the anchor bolts through corresponding holes and then tightened with nuts. The anchor bolts can transfer the force borne by the steel structure to the concrete beam, realizing the connection between the two. This method is often used in situations where the steel structure is subjected to relatively small horizontal forces and there is a certain requirement for adaptability to structural deformation. In order to further improve the connection strength between the steel structure and the concrete beam, we designed a composite reinforcement connection component for the steel structure and the concrete beam. After the steel structure is installed on the concrete beam, it is reinforced and connected by tying, which improves the load-bearing capacity of the steel structure. Utility Model Content

[0003] The purpose of this invention is to provide a composite reinforcement connection component for steel structures and concrete beams. This component has the advantage of being installed on the concrete beam and then reinforced by tying, thereby improving the load-bearing capacity of the steel structure and solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A composite reinforcement connection component for steel structure and concrete beam includes a U-shaped cover installed above the concrete beam body and two symmetrical sleeves fitted on the top flange of the I-beam. Two symmetrical fixing rings are welded on the U-shaped cover, and a fixing ring is welded on the top of the sleeve. A tie assembly is provided between the fixing rings and the fixing rings. The tie assembly includes a threaded tube between the sleeve and the fixing ring. The inner cavities at both ends of the threaded tube are threaded with threaded rods. The end of the threaded rod away from the threaded tube extends to the outside of the threaded tube and is fixedly connected with a hook. The two hooks are respectively hooked on the fixing rings.

[0005] Preferably, an operating hole for inserting a reinforcing bar is provided in the middle of the surface of the threaded pipe.

[0006] Preferably, two symmetrical positioning strips are fixedly connected to the lower part of the top flange of the I-beam, and the housing is provided with positioning grooves that fit onto the surface of the positioning strips.

[0007] Preferably, two symmetrical nuts are welded to both sides of the U-shaped cover, and the inner cavity of the nuts is threaded with a screw, the end of the screw passing through the U-shaped cover and abutting against the surface of the concrete beam body.

[0008] Preferably, the I-beam is installed on the right side of the concrete beam body using chemical bolts, angle brackets, and bolts.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model involves placing a U-shaped cover on the concrete beam body and tightening it by screwing in screws. Then, two sleeves are placed on the I-beam. The two hooks on the tie assembly are respectively hooked onto the first and second fixing rings. Then, the threaded tube is rotated to move the two hooks towards each other and tighten them, thereby achieving the tie between the concrete beam body and the I-beam. This achieves the purpose of strengthening the connection between the concrete beam and the steel structure after installation by tying, thus improving the load-bearing capacity of the steel structure.

[0011] 2. The present invention, through the setting of the operating hole, allows users to easily rotate the threaded pipe by inserting tools such as steel bars into the inner cavity of the operating hole, thus bringing convenience to the user.

[0012] 3. By using the positioning strip and positioning groove in combination, when the sleeve is fitted onto the flange of the I-beam, the positioning groove on the sleeve will fit onto the positioning strip, which will limit the position of the sleeve and prevent the sleeve from sliding left and right on the surface of the I-beam.

[0020] In the following description, embodiments of the composite reinforcement connection assembly for steel structures and concrete beams of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a composite reinforcement connection assembly for a steel structure and a concrete beam according to an embodiment of the present invention. It includes a U-shaped cover 2 installed above the concrete beam body 1 and two symmetrical sleeves 4 fitted onto the top flange of an I-beam 3. The I-beam 3 is installed on the right side of the concrete beam body 1 using chemical bolts, angle brackets, and bolts. Two symmetrical positioning strips 8 are fixedly connected to the lower part of the top flange of the I-beam 3. Positioning grooves 9 are formed on the sleeves 4 and fitted onto the surfaces of the positioning strips 8. Through the cooperation of the positioning strips 8 and the positioning grooves 9, when the sleeves 4 are fitted onto the flange of the I-beam 3, the positioning grooves 9 on the sleeves 4 engage with the positioning strips 8, thus limiting the movement of the sleeves 4 and preventing them from sliding left and right on the surface of the I-beam 3. Two symmetrical fixing rings 5 ​​are welded to the U-shaped cover 2, and two symmetrical nuts 10 are welded to both sides of the U-shaped cover 2. The inner cavity of the cap 10 is threaded with a screw 11. The end of the screw 11 passes through the U-shaped cover 2 and abuts against the surface of the concrete beam body 1. The top of the sleeve 4 is welded with a fixing ring 2 6. A tie assembly 7 is provided between the fixing ring 1 5 and the fixing ring 2 6. The tie assembly 7 includes a threaded tube 71 between the sleeve 4 and the fixing ring 1 5. The inner cavities at both ends of the threaded tube 71 are threaded with threaded rods 72. The end of the threaded rod 72 away from the threaded tube 71 extends to the outside of the threaded tube 71 and is fixedly connected with a hook 73. An operating hole 74 for inserting a steel bar is opened in the middle of the surface of the threaded tube 71. The operating hole 74 allows the user to easily insert a steel bar or other tool into the inner cavity of the operating hole 74 to rotate the threaded tube 71, which brings convenience to the user. The two hooks 73 are respectively hooked on the fixing ring 1 5 and the fixing ring 2 6.

[0022] Working principle: When using this utility model, the U-shaped cover 2 is placed on the surface of the concrete beam body 1. Then, the four screws 11 are turned. The four screws 11 are moved and rotated by the nuts 10 until the screws 11 are against the surface of the concrete beam body 1, thus fixing the U-shaped cover 2. Next, the sleeve 4 is placed on the top flange of the I-beam 3 and the positioning groove 9 is placed on the surface of the positioning strip 8. Then, the two hooks 73 on the tie assembly 7 are hung on the fixing ring 5 and the fixing ring 6 respectively. The steel bar is picked up and inserted into the inner cavity of the operating hole 74 to operate the threaded tube 71 and rotate it, so that the two threaded rods 72 move towards each other, and thus the two hooks 73 move towards each other, thereby realizing the tie between the concrete beam body 1 and the I-beam 3.

[0023] In summary, this composite reinforcement connection assembly for steel structure and concrete beam achieves its purpose by fitting a U-shaped cover 2 onto the concrete beam body 1 and tightening it with screws 11, then fitting two sleeves 4 onto the I-beam 3, and attaching two hooks 73 on the tie assembly 7 to the fixing ring 5 and fixing ring 6 respectively. Then, by rotating the threaded tube 71, the two hooks 73 move towards each other and tighten, thus achieving the connection between the concrete beam body 1 and the I-beam 3. This reinforces the connection between the concrete beam and the steel structure after installation, thereby improving the load-bearing capacity of the steel structure.
