Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel, in particular to a rust-proof and corrosion-resistant threaded steel. Background Art

[0002] Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar. It usually has longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs is spiral, herringbone, crescent, etc. Ribbed steel bars mainly bear tensile stress in concrete. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

[0003] The Chinese utility model patent with the authorization announcement number "CN220598716U" specifically states that "the wear-resistant layer, the reinforced steel core, the corrosion-resistant layer and the waterproof layer cooperate with each other, and the wear-resistant layer prevents the reinforced steel core from being damaged due to collision during use. The corrosion-resistant layer fixedly connected to the right side of the wear-resistant layer increases the service life of the reinforced steel core. The waterproof layer fixedly connected to the right side of the corrosion-resistant layer prevents the reinforced steel core from being affected by water molecules in the outside air, thereby achieving the purpose of protecting the reinforced steel core to increase the service life";

[0004] It increases its service life by adding a corrosion-resistant layer on the surface of the wear-resistant layer, and improves its anti-rust effect by adding a waterproof layer on the surface of the corrosion-resistant layer. Although it theoretically has the above-mentioned corrosion-resistant and rust-proof effects, rebars are easily bumped into each other during production, packaging, transportation and use, causing partial shedding of the above-mentioned protective layer, thereby reducing its anti-rust and corrosion-resistant effects. Therefore, its anti-rust and corrosion-resistant effects are poor. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a rust-proof and corrosion-resistant threaded steel bar, which can effectively solve the problem of poor rust-proof and corrosion-resistant effects of the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a rust-proof and corrosion-resistant threaded steel, a rust-proof and corrosion-resistant threaded steel, comprising a threaded steel component, the threaded steel component comprising a threaded steel body, a plurality of mounting seats all being sleeved on the outer ring wall of the corresponding threaded steel body, and upper and lower adjacent mounting seats being mutually clamped, and a plurality of limit assemblies all comprising an arc-shaped rubber extrusion sheet installed in the mounting seat in an elastically telescopic sliding manner and in conflict with the corresponding threaded steel body.

[0008] Furthermore, the threaded steel assembly also includes two steel bars fixedly installed on the surface of the threaded steel body and distributed in a centrally symmetrical manner, and also includes a plurality of convex edges distributed in an axially symmetrical manner about the two steel bars. The threaded steel body, steel bars and convex edge surfaces are all sprayed with an epoxy paint layer.

[0009] Furthermore, a number of circular holes are provided on both sides of the mounting seat for facilitating the corresponding threaded steel components to pass through and are distributed at equal intervals. A movable cavity is also provided in the mounting seat. A small movable opening is provided between the movable cavity and the circular holes. A large movable opening is provided on the top of the corresponding mounting seat through the movable cavity.

[0010] Furthermore, a plurality of springs are installed at the bottom of the movable cavity, and a limit block installed at the bottom of the movable cavity is arranged in the inner circle of the plurality of springs. A strip slot is opened at the bottom end of the mounting seat, and handles are installed at both ends of the mounting seat.

[0011] Furthermore, the limiting assembly also includes a strip socket fixedly mounted on the top of a plurality of arc-shaped rubber extrusion sheets and inserted into the corresponding strip slots. The strip socket is telescopically and slidably mounted in the large movable opening, and the bottom is connected to the corresponding spring.

[0012] Furthermore, the height of the strip-shaped socket is greater than the depth of the corresponding strip-shaped slot, and the arc-shaped rubber extrusion sheets are respectively telescopically and slidably installed in the corresponding small movable openings.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. Set up several upper and lower clamping mounting seats to completely separate several threaded steel components up and down, left and right, so that the probability of contact between several threaded steel components stacked together is reduced, thereby reducing bumps and collisions, avoiding the epoxy anti-rust layer on the surface of the threaded steel components from falling off, and making the threaded steel components have a long-term anti-rust and corrosion effect;

[0015] 2. An arc-shaped rubber extrusion sheet for limiting and fixing the threaded steel component is arranged in the circular hole of the mounting seat for the threaded steel component to pass through. When the upper-layer mounting seat is connected to the lower-layer mounting seat, the arc-shaped rubber extrusion sheet is forced to extend into the circular hole and squeeze and contact the surface of the threaded steel component to limit the shaking of the threaded steel component, so that the threaded steel inserted into the circular hole of the mounting seat remains relatively stable with the mounting seat and is not easy to shake, thereby reducing the wear on the surface of the threaded steel component, and making the threaded steel component further have a long-term anti-rust and corrosion effect.

When the upper-layer mounting seat 2 is plugged into the lower-layer mounting seat 2, the arc-shaped rubber extrusion sheet 32 ​​is forced to be squeezed and conflicted with the surface of the corresponding threaded steel body 11, reducing shaking and collision, avoiding damage and falling off of the protective layer, and improving the rust-proof and corrosion-resistant effect. In addition, since the threaded steel component 1 will not be placed directly on the ground, drainage is convenient, and the reserved gaps between the threaded steel components 1 are convenient for manual or mechanical material collection.

[0026] Example 2

[0027] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the threaded steel component 1 also includes two steel bars 12 fixedly installed on the surface of the threaded steel body 11 and distributed in a central symmetrical manner, and also includes a plurality of convex edges 13 distributed axially symmetrically about the two steel bars 12. The surfaces of the threaded steel body 11, the steel bars 12 and the convex edges 13 are sprayed with an epoxy coating layer 14, and the surface of the epoxy coating layer 14 is also protected by a hot-dip galvanizing layer, which can passivate the surface of the steel material, thereby preventing corrosion. A plurality of circular holes 21 are provided on both sides of the mounting seat 2, which are convenient for the corresponding threaded steel components 1 to pass through and are distributed at equal intervals. The inner hole walls of the circular holes 21 are filled with rubber rings, which can reduce the wear between the surface of the threaded steel component 1 and the inner hole walls of the circular holes 21. An active cavity 22 is also provided in the mounting seat 2, and a small active opening 23 is provided between the active cavity 22 and the plurality of circular holes 21. The active cavity 22 passes through the corresponding mounting seat 2 and a large active opening 24 is provided on the top. The active cavity 22 A plurality of springs 25 are installed at the bottom of the cavity, and the springs 25 provide elastic restoring force, so that after the upper mounting seat 2 is taken out, the arc-shaped rubber extrusion piece 32 in the circular hole 21 of the lower mounting seat 2 is automatically retracted, which is convenient for the threaded steel component 1 to take out the material, and the inner circles of the plurality of springs 25 are provided with limit blocks 26 installed at the bottom of the active cavity 22, which play a guiding and limiting role for the spring 25 to prevent the spring 25 from bending or excessive compression, causing irreversible deformation, and the bottom end of the mounting seat 2 is provided with a strip slot 27, and handles 28 are installed at both ends of the mounting seat 2 to facilitate the transportation and movement of the mounting seat 2, and the limiting component 3 also includes a strip socket 31 fixedly installed on the top of the plurality of arc-shaped rubber extrusion pieces 32 and inserted into the corresponding strip slot 27, the strip socket 31 is telescopically and slidably installed in the large active opening 24, and the bottom is connected to the corresponding spring 25, the height of the strip socket 31 is greater than the groove depth of the corresponding strip slot 27, and the arc-shaped rubber extrusion piece 32 is telescopically and slidably installed in the corresponding small active opening 23.

[0028] The remaining structures are the same as those of Example 1.

[0029] The working principle of the utility model is as follows:

[0030] First, the two ends of the threaded steel components 1 are respectively passed through the circular holes 21 of the corresponding mounting seats 2, and several threaded steel components 1 are arranged in parallel, with equal spacing between them;

[0031] Secondly, the strip slots 27 at the bottom of the two mounting seats 2 are respectively inserted into the strip sockets 31 at the top of the two mounting seats 2 that have been placed on the ground. Since the height of the strip sockets 31 is less than the groove depth of the strip slots 27, when the upper and lower layers of the mounting seats 2 are stacked on each other, the strip sockets 31 will be forced to telescope and slide in the corresponding large movable openings 24, thereby compressing the corresponding springs 25, so that the springs 25 deform to obtain elastic restoring force, and at the same time, the arc-shaped rubber extrusion sheet 32 ​​installed at the bottom of the strip socket 31 telescopes and slides in the corresponding small movable openings 23, thereby squeezing and contacting the surface of the corresponding threaded steel component 1, thereby limiting and fixing the threaded steel component 1;

[0032] Finally, the threaded steel components 1 are respectively passed through the circular holes 21 of the corresponding mounting seats 2, and several threaded steel components 1 are limited and fixed in an upper and lower plug-in manner, so that a gap is reserved between two adjacent threaded steel components 1 in the upper, lower, left and right directions, so that they will not directly contact and wear each other. At the same time, since the surface of each threaded steel component 1 is not covered or blocked, the surface moisture is easier to evaporate and is not easy to rust and rot.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
