Description

Technical Field

[0001] The present application relates to the technical field of steel tie bars, and specifically to the replacement of masonry tie bars with punched thin-walled steel strips. Background Art

[0002] Rebar tie bars refer to a method of using steel bars for tie reinforcement in concrete structures in order to increase the tensile strength and ductility of concrete components. Steel bars are usually set in the tensile area of ​​the concrete component. Through the bonding effect between the steel bars and concrete, the component can better resist the tensile force when subjected to stress, thereby improving the overall performance and safety of the structure.

[0003] Traditional steel tie bars are made by post-embedded reinforcement. Their pull-out force is greatly affected by the depth of the drilling hole, whether the hole is clean, whether the quality of the embedding glue is qualified, and whether the workers are diligent in their duties. The quality stability is poor, which greatly reduces the masonry's ability to resist damage and collapse under earthquakes.

[0004] In view of the above-mentioned existing technical problems, it is proposed to solve the problem by replacing the masonry tie bars with thin-walled steel strips with punched holes. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a thin-walled steel strip with punching holes to replace the masonry tie bars, which has the advantages of good seismic strength and high seismic structural grade.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a thin-walled steel strip with punching holes replaces the masonry tie bars, comprising a structural body and a concrete wall, wherein the steel strip located on the structural body is arranged in the concrete wall;

[0007] The surface of the steel belt is continuously penetrated with punching holes, and a connecting structure is arranged between the steel belt and the structural main body.

[0008] Furthermore, the steel belt and the structural body are both provided with rivet holes, and rivets are passed through the rivet holes.

[0009] Furthermore, an extension belt is slidably extended inside the steel belt, and the extension belt is attached to the inner wall of the steel belt and slidably extends to the outside of the steel belt. Punching holes are also formed on the extension belt.

[0010] Furthermore, a limit strip is fixedly installed on one end of the extension strip located inside the steel strip, the limit strip slides in contact with the upper and lower side walls of the steel strip, and the length of the limit strip is greater than the opening length of the steel strip.

[0011] Furthermore, connecting sleeves are fixedly installed at the upper and lower edges of the steel belt.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The thin-walled steel belt with punching holes replaces the masonry tie bars. The steel belt is provided to replace the masonry tie bars. The steel belt does not need to be pre-drilled for connection. Therefore, the pull-out force of the steel belt is not limited by the cleanliness of the hole and the quality of the anchoring mortar. The punching holes allow the concrete slurry to pass through, thereby increasing the bonding force between the concrete wall and the steel belt. The connection is made by riveting and mechanical expansion bolts, thereby improving the seismic stability of on-site installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-5 The punched thin-walled steel strip in this embodiment replaces the masonry tie bar, including a structural body 1 and a concrete wall 2, wherein the concrete wall 2 is provided with a steel strip 3 located on the structural body 1, wherein the structural body 1 is specifically a structural column steel bar, which is implanted in the concrete wall 2 to play the following roles:

[0022] 1. Bear longitudinal loads, such as pressure, tension, etc., generated when the column is subjected to stress;

[0023] 2. Resist bending and shearing forces, increase the bending and shearing capacity of the columns, so that the columns can better resist the bending and shearing forces when subjected to lateral loads or seismic forces, and ensure the overall stability and safety of the structure;

[0024] 3. Increase the ductility of the column, that is, when the column is subjected to large deformation or displacement, it can maintain a certain bearing capacity and deformation capacity, delay the destruction process of the structure, and improve the seismic performance of the structure.

[0025] In this embodiment, the steel strip 3 replaces the masonry tie bars connected to the structural body 1 in the existing structure, that is, replaces the embedded bars for increasing the tensile strength of the concrete member;

[0026] Furthermore, punching holes 4 are continuously formed on the surface of the steel strip 3 .

[0027] With this design, the mortar in the concrete wall 2 built by concrete can directly pass through the punching holes 4 to complete the bonding to the opposite side of the steel strip 3, that is, the bonding force between the mortar and the steel strip 3 in the concrete structure of the concrete wall 2 is stronger than that of the embedded reinforcement.

[0028] It should be noted that the steel belt 3 and the structural body 1 are connected by providing a connecting structure.

[0029] See also Figure 4 In one embodiment, the steel belt 3 and the structural body 1 in this embodiment are both provided with rivet holes 5 , and rivets 6 are passed through the rivet holes 5 .

[0030] In a specific implementation, the rivet 6 is inserted into the riveting hole 5 so that the rivet head on one side of the rivet 6 is in close contact with the surface of the steel strip 3, and then one end of the rivet rod is upset to form a rivet head that is in close contact with the outside of the structural body 1, so that the steel strip 3 and the structural body 1 are riveted and fixed.

[0031] In this embodiment, an extension belt 7 is slidably extended inside the steel belt 3. The extension belt 7 is attached to the inner wall of the steel belt 3 and slidably extends to the outside of the steel belt 3. The extension belt 7 is also provided with punching holes 4 to improve the bonding strength between the extension belt 7 and the concrete mortar.

[0032] Preferably, a limit strip 8 is fixedly installed on one end of the extension strip 7 located inside the steel strip 3 , and the limit strip 8 slides against the upper and lower side walls of the steel strip 3 , and the length of the limit strip 8 is greater than the opening length of the steel strip 3 .

[0033] Such a design can prevent the extension belt 7 from falling out of the steel belt 3, thereby improving the stability of the overall structure.

[0034] See also Figure 2 In another embodiment, in order to connect the steel belt 3, in this embodiment, connecting sleeves 9 are fixedly installed at the upper and lower edges of the steel belt 3.

[0035] In a specific implementation, mechanical expansion bolts are extended to the inside of the concrete wall 2, and then one end of the expansion bolt is docked with the connecting sleeve 9, so that the steel belt 3 can be bolted to the concrete structure.

[0036] The working principle of the above embodiment is:

[0037] According to the on-site installation requirements, a suitable method of connecting the steel strip 3 is selected, which is riveting the steel strip 3 to the steel column of the main structure 1, or fixing it to the concrete wall 2 with mechanical expansion bolts. Specifically, the rivet 6 is inserted into the riveting hole 5, so that the rivet head on one side of the rivet 6 is closely attached to the surface of the steel strip 3, and then one end of the rivet rod is upset to form a rivet head that is attached to the outside of the main structure 1, so that the steel strip 3 and the main structure 1 are riveted and fixed;

[0038] Mechanical expansion bolts are extended to the interior of the concrete wall 2, and then one end of the expansion bolt is docked with the connecting sleeve 9 to achieve bolt fixation of the steel belt 3 relative to the concrete structure. The concrete slurry in the concrete wall 2 can pass through the punching hole 4 to complete the connection with the opposite side of the steel belt 3, which helps to increase the bonding force between the mortar and the steel belt and has strong earthquake resistance.
