Description

Technical Field

[0001] The utility model relates to the technical field of steel bar welded meshes, in particular to a cold-rolled ribbed steel bar welded mesh. Background Technique

[0002] In some building constructions, higher strength requirements are imposed on steel bar welded meshes. Currently, cold-rolled ribbed steel bars are mainly used to make steel bar welded meshes. However, the strength of cold-rolled ribbed steel bars is only improved compared with ordinary steel bars, and the strength of the steel bar welded meshes made of cold-rolled ribbed steel bars still needs to be improved, and it cannot be applied to buildings with high strength requirements for steel bar welded meshes;

[0003] The existing Chinese patent CN215631075U discloses a compressive crack-resistant cold-rolled ribbed steel bar welded mesh. The compressive crack-resistant cold-rolled ribbed steel bar welded mesh is provided with a support member in the grid formed by the first steel bar and the second steel bar. The support member supports the first steel bar and the second steel bar, and at the same time also improves the connection strength between the first steel bar and the second steel bar, and finally improves the overall strength of the steel bar welded mesh, achieving the effect of compressive crack resistance and being convenient for application to buildings with high strength requirements for steel bar welded meshes;

[0004] However, in order to install the support member on the above-mentioned compressive crack-resistant cold-rolled ribbed steel bar welded mesh, welding grooves and connection grooves need to be opened on the first steel bar and the second steel bar. First, the grooving process on the steel bar is difficult, and second, it will also reduce the strength of the steel bar itself. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cold-rolled ribbed steel bar welded mesh to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cold-rolled ribbed steel bar welded mesh, including a first steel bar and a second steel bar. There are multiple first steel bars and second steel bars, and the multiple first steel bars and second steel bars are vertically and alternately arranged. The first steel bar and the second steel bar are welded together, and a support member is arranged between the first steel bar and the second steel bar;

[0007] The support member includes a support cylinder. A through groove is opened on the outer wall of the support cylinder. A fixing plate is fixedly installed on the inner wall of the support cylinder. A threaded rod is rotatably connected to the inner wall of the fixing plate through a bearing. A lifting block is threadedly sleeved on the outer wall of the threaded rod. A limiting groove is opened on the outer wall of the lifting block. A support rod is hinged to the inner wall of the limiting groove through a pin shaft. The support rod extends out from the through groove. A support plate is fixedly installed at the end of the support rod away from the lifting block. The support plate is welded to the first steel bar and the second steel bar. There are two lifting blocks, which respectively correspond to the first steel bar and the second steel bar. There are two limiting grooves on the lifting block, which respectively correspond to two adjacent first steel bars or second steel bars.

[0008] Further, a shielding plate is fixedly installed at the top end of the threaded rod. The shielding plate is rotatably arranged in the support cylinder, and a plum blossom groove is formed at the top of the shielding plate.

[0009] Further, an outer frame is arranged on the outer sides of the first steel bar and the second steel bar. Embedded blocks are welded at the joints of the ends of the first steel bar and the second steel bar and the outer frame, and the embedded blocks are welded on the outer frame.

[0010] Further, welding grooves are formed in the outer frame. The welding grooves on two adjacent outer frames are communicated, and a welding plate is welded in the welding grooves. The adjacent outer frames are fixedly connected by rivets.

[0011] Further, notches are formed in the first steel bar and the second steel bar, and the notches are located at the welding positions of the first steel bar and the second steel bar.

[0012] Further, connecting mesh steel bars are welded at the edges of the first steel bar and the second steel bar. There are two upper and lower layers of the connecting mesh steel bars, and the ends of the connecting mesh steel bars are welded on the outer frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

The connection strength of the first steel bar and the second steel bar is increased through the support component, thereby improving the compressive crack resistance effect of the whole steel bar welded mesh. At the same time, there is no need to perform secondary processing operations such as grooving on the first steel bar and the second steel bar.

[0015] The support rod is connected with the liftable lifting block, so that when installing the support component, the support rod can be retracted into the support cylinder, and then the support plate can extend into the gap between the first steel bar and the second steel bar. Then rotate the threaded rod to make the lifting block move downward, and then push the support rod out of the support cylinder. The movement of the support rod drives the movement of the support plate, and the support plate is pressed on the first steel bar and the second steel bar to realize the positioning and installation of the support component. Finally, the support plate can be welded and fixed. There is no need to install the support component between the first steel bar and the second steel bar when welding the first steel bar and the second steel bar, and the construction requirements are lower.

Specific implementation manners

[0023] 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 of the embodiments.

[0024] Please refer to Figures 1-6 , the present utility model provides a technical solution: a cold-rolled ribbed steel bar welded mesh, including a first steel bar 1 and a second steel bar 2. There are multiple first steel bars 1 and second steel bars 2, and the multiple first steel bars 1 and second steel bars 2 are vertically and crosswise arranged. The first steel bar 1 and the second steel bar 2 are welded together, and a support component 3 is arranged between the first steel bar 1 and the second steel bar 2;

[0025] The support member 3 includes a support cylinder 301. A through groove 302 is formed in the outer wall of the support cylinder 301. A fixing plate 305 is fixedly installed on the inner wall of the support cylinder 301. A threaded rod 306 is rotatably connected to the inner wall of the fixing plate 305 through a bearing. A lifting block 308 is sleeved on the outer wall of the threaded rod 306 in a threaded manner. A limiting groove 307 is formed in the outer wall of the lifting block 308. A support rod 303 is hinged to the inner wall of the limiting groove 307 through a pin shaft. The support rod 303 extends out of the through groove 302. A support plate 304 is fixedly installed at one end of the support rod 303 away from the lifting block 308. The support plate 304 is welded to the first steel bar 1 and the second steel bar 2. There are two lifting blocks 308, which respectively correspond to the first steel bar 1 and the second steel bar 2. There are two limiting grooves 307 on the lifting blocks 308, which respectively correspond to two adjacent first steel bars 1 or second steel bars 2. By welding the support plate 304 to the first steel bar 1 and the second steel bar 2, the entire support member 3 is connected to the first steel bar 1 and the second steel bar 2. The connection strength of the first steel bar 1 and the second steel bar 2 is increased through the support member 3, thereby improving the compressive crack resistance effect of the entire welded steel bar mesh. At the same time, there is no need to perform secondary processing operations such as grooving on the first steel bar 1 and the second steel bar 2. The support rod 303 is connected to the liftable lifting block 308, so that when installing the support member 3, the support rod 303 can be retracted into the support cylinder 301, so that the support plate 304 can extend into the gap between the first steel bar 1 and the second steel bar 2. Then rotate the threaded rod 306 to make the lifting block 308 move downward, and then push the support rod 303 out of the support cylinder 301. The movement of the support rod 303 drives the support plate 304 to move, and the support plate 304 is pressed on the first steel bar 1 and the second steel bar 2 to realize the positioning and installation of the support member 3. Finally, the support plate 304 is welded and fixed. This design method can install the support member 3 for reinforcement after the welded steel bar mesh has been welded, without installing the support member 3 between the first steel bar 1 and the second steel bar 2 when welding the first steel bar 1 and the second steel bar 2, and the construction requirements are lower;

[0026] A shielding plate 9 is fixedly installed at the top end of the threaded rod 306. The shielding plate 9 is rotatably arranged in the support cylinder 301. A plum blossom groove is formed in the top of the shielding plate 9. The shielding plate 9 is provided to protect the threaded rod 306, and the plum blossom groove is provided to make it more convenient to rotate the shielding plate 9;

[0027] An outer frame 4 is arranged on the outer sides of the first steel bar 1 and the second steel bar 2. Embedding blocks 10 are welded at the connection positions of the ends of the first steel bar 1 and the second steel bar 2 and the outer frame 4. The embedding blocks 10 are welded to the outer frame 4. The outer frame 4 is provided to fix and limit the welded steel bar mesh formed by the first steel bar 1 and the second steel bar 2, and it is also convenient to connect multiple welded steel bar meshes together. The embedding blocks 10 are provided to increase the connection strength between the first steel bar 1 and the second steel bar 2 and the outer frame 4;

[0028] The outer frame 4 is provided with welding grooves 6. The welding grooves 6 on two adjacent outer frames 4 are communicated, and a welding plate 5 is welded in the welding groove 6. The adjacent outer frames 4 are fixedly connected by rivets 7. The welding plate 5 and the welding groove 6 are provided for connecting adjacent outer frames 4, and the rivets 7 are provided for strengthening the connected outer frames 4.

[0029] Notches are provided on the first steel bar 1 and the second steel bar 2, and the notches are located at the welding joints of the first steel bar 1 and the second steel bar 2. The provision of the notches can increase the welding surface of the first steel bar 1 and the second steel bar 2, making the welding between the first steel bar 1 and the second steel bar 2 more firm.

[0030] Connecting mesh steel bars 8 are welded at the edges of the first steel bar 1 and the second steel bar 2. There are two upper and lower layers of connecting mesh steel bars 8, and the ends of the connecting mesh steel bars 8 are welded to the outer frame 4, increasing the compressive and tensile strength at the edges of the steel bar welding mesh formed by welding the first steel bar 1 and the second steel bar 2, making the overall strength of the steel bar welding mesh greater.

[0031] Working principle: During use, a plurality of first steel bars 1 and second steel bars 2 are welded into a steel bar welding mesh, and then the outer frame 4 is welded outside the steel bar welding mesh. When it is necessary to reinforce and strengthen the steel bar welding mesh, the support member 3 is placed in the gaps where the first steel bar 1 and the second steel bar 2 intersect, so that the end of the support plate 304 contacts the outer walls of the first steel bar 1 and the second steel bar 2. Then, the baffle 9 is rotated to drive the threaded rod 306 to rotate. The rotation of the threaded rod 306 drives the lifting block 308 to move downward. The downward movement of the lifting block 308 pushes the support rod 303 out of the support cylinder 301, thereby pushing the support plate 304, so that the support plate 304 is tightly pressed against the first steel bar 1 and the second steel bar 2. Then, the support plate 304 can be welded and fixed. Because the four support plates 304 are simultaneously pushed outward by the same distance, it is ensured that the support plates 304 can be tightly pressed against the first steel bar 1 and the second steel bar 2 at the same time, achieving the purpose of automatic positioning.

[0032] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
