Description

Technical Field

[0001] The utility model relates to the technical field of anchor plates, in particular to a rigid anchoring structure of an anchor plate. Background Technique

[0002] An anchor plate is a component of an engineering structure. Anchor plates are mainly used for connecting and fixing structures, and are widely used in engineering such as bridges, buildings, and ships. Anchoring means that the steel bars are wrapped in concrete to enhance the connection between the concrete and the steel bars, making the building more firm. The purpose is to enable the two to work together to bear various stresses (cooperate to bear the pressure, tension, bending moment, and torque generated by various loads).

[0003] For example, the disclosed document with the application number 202121381797.6 discloses a threaded steel bar anchoring structure. The prestressed tendon of this utility model is detachably connected to the components embedded in the anchoring seat, and the connection structure is simple and the construction is convenient. During construction, the expansion sleeve is pre-tensioned to be deformed by extrusion, and then connected to the anchor backing plate as a whole, which can effectively ensure the reliable connection between the prestressed tendon and the threaded steel bar anchoring structure. However, for this rigid anchoring structure of the anchor plate, the steel bar parts are directly inserted into the concrete interior, and the anchoring surface of the entire concrete part is only the tiny surface of the steel bars, which is an easy anchoring method. If the exposed end of the steel bar is subjected to pressure, it may form a prying structure, causing the concrete to crack. Moreover, after the concrete is formed and during use, due to the thermal expansion or contraction of the concrete itself, the steel bars may also deform or leave gaps and fall off, making it difficult to carry out the anchoring work stably.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a rigid anchoring structure of an anchor plate is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rigid anchoring structure of an anchor plate 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 rigid anchoring structure of an anchor plate, including an anchor plate main body, installation holes are respectively penetrated and opened at the four corners above the surface of the anchor plate main body, positioning steel bars are slidably penetrated and arranged inside the installation holes, a grouting pipe is fixedly installed at the front end of the anchor plate main body, and spiral steel bars are fixedly arranged below the surface of the anchor plate main body.

[0007] Preferably, the positioning steel bars penetrate the installation holes and are inserted into the concrete interior, and the shape of the positioning steel bars is set as an "L" shape.

[0008] Preferably, a sunken groove is opened in the middle above the surface of the anchor plate main body, and an anchor ring is inserted and arranged inside the sunken groove.

[0009] Preferably, perforations are provided on both the inner surface of the sinking groove and the surface of the anchor ring, and the perforations of the sinking groove and the anchor ring correspond to each other.

[0010] Preferably, wedge-shaped pieces are provided inside the perforations of the anchor ring. The wedge-shaped pieces are provided with openings, have a certain elastic force themselves, and the diameter of the wedge-shaped pieces is slightly larger than that of the perforations.

[0011] Preferably, steel strands are penetrated through the interiors of the perforations, and the steel strands penetrate through the interiors of the wedge-shaped pieces.

[0012] Preferably, a galvanized metal corrugated pipe is fixedly provided inside the spiral rib on the lower part of the outer surface of the anchor plate body, and the galvanized metal corrugated pipe covers the outside of the steel strand.

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

[0014] 1. Through the settings of the mounting holes, positioning ribs, grouting pipes and spiral ribs, the present utility model uses the positioning ribs to penetrate the mounting holes and insert into the concrete. The "L"-shaped bent part at the front end of the positioning rib closely adheres to the anchor plate body, enabling the anchor plate body to be pre-positioned and closely attached to the concrete surface, thereby improving the tightness of the fit. When the anchor plate body is subsequently pushed to squeeze the concrete and sink, it can also provide guidance for the anchor plate body, effectively preventing the anchor plate body from shifting, thereby improving the stability of the anchoring and sinking work. The spiral rib is inserted into the holes pre-opened inside the concrete. With its shape, it has a certain elastic force and can provide pre-installation stress for the anchor plate body. When the anchor plate body sinks, it will squeeze the spiral rib to contract. Concrete is poured into the holes through the grouting pipe to fix the amount of contraction of the squeezed spiral rib, so as to adapt to the expansion stress of the concrete, making the anchor plate body more stable after sinking and fixing, effectively adapting to the later thermal expansion and contraction of the concrete, and avoiding the situation of concrete cracking caused by the extrusion of the anchor plate body and deformed concrete;

[0015] 2. Through the settings of the perforations, wedge-shaped pieces, steel strands and galvanized metal corrugated pipes, the present utility model uses the perforations to stably insert the steel strands. Multiple steel strands form multiple support points in the concrete holes. After concrete is poured into the holes, the steel strands can be integrated with the concrete to provide a rigid fixing tension for the anchor plate body, effectively preventing the anchor plate body from falling off. The galvanized metal corrugated pipe covers the surface of the steel strand, which can effectively avoid large-area corrosion of the steel strand by moisture, thereby extending the service life of the steel strand and prolonging the service duration of the anchoring of the anchor plate body. The wedge-shaped pieces are sleeved on the upper ends of the steel strands and cooperate with the perforations to be squeezed, so that the wedge-shaped pieces clamp the steel strands and tightly fix them at the fixed positions of the perforations, improving the insertion depth of the steel strands after passing through the anchor plate body and preventing the steel strands from shifting before pouring concrete.

[0020] 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 the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-3 shown, an anchor plate rigid anchoring structure includes an anchor plate main body 1. Installation holes 2 are penetrated and opened at the four corners above the surface of the anchor plate main body 1. Positioning ribs 3 are slidably penetrated and arranged inside the installation holes 2. A grouting pipe 4 is fixedly installed at the front end of the anchor plate main body 1. A spiral rib 5 is fixedly arranged below the surface of the anchor plate main body 1.

[0022] By adopting the above technical solution, when the anchor plate main body 1 is pushed to squeeze the concrete and sink, the positioning rib 3 can provide guidance for the anchor plate main body 1; the spiral rib 5 is inserted into the holes pre-opened inside the concrete. Utilizing its shape, it has a certain elastic force and can provide pre-installation stress for the anchor plate main body 1. When the anchor plate main body 1 sinks, it will squeeze the spiral rib 5 to contract. Concrete is poured into the holes through the grouting pipe 4 to fix the extrusion and contraction amount of the spiral rib 5, so as to be able to adapt to the expansion stress of the concrete and make the anchor plate main body 1 more stable after sinking and fixing.

[0023] Furthermore, the positioning rib 3 penetrates the installation hole 2 and is inserted into the concrete interior, and the positioning rib 3 is formed in an "L" shape.

[0024] By adopting the above technical solution, the positioning rib 3 penetrates the installation hole 2 and is inserted into the concrete. The "L" - shaped bent part at the front end of the positioning rib 3 is closely attached to the anchor plate main body 1, so that the anchor plate main body 1 can be pre - positioned and closely attached to the concrete surface.

[0025] Furthermore, a sinking groove 6 is opened in the middle above the surface of the anchor plate main body 1, and an anchor ring 8 is inserted and arranged inside the sinking groove 6.

[0026] By adopting the above technical solution, the anchor ring 8 can be inserted into the sinking groove 6 to match with the anchor plate body 1 and serve as a driving member.

[0027] Furthermore, perforations 7 are provided on both the inner surface of the sinking groove 6 and the surface of the anchor ring 8, and the perforations 7 of the sinking groove 6 and the perforations 7 of the anchor ring 8 correspond to each other; a wedge-shaped clip 9 is arranged inside the perforation 7 of the anchor ring 8. The wedge-shaped clip 9 is provided with an opening, has a certain elastic force itself, and the diameter of the wedge-shaped clip 9 is slightly larger than that of the perforation 7.

[0028] By adopting the above technical solution, the wedge-shaped clip 9 can be contracted by using the opening, and the perforation 7 exerts an extrusion force on the wedge-shaped clip 9.

[0029] Furthermore, steel strands 10 are arranged through the inside of the perforation 7, and the steel strands 10 pass through the inside of the wedge-shaped clip 9.

[0030] By adopting the above technical solution, the wedge-shaped clip 9 clamps the steel strands 10 and firmly fixes them at the fixed position of the perforation 7, improving the insertion depth of the steel strands 10 after passing through the anchor plate body 1 and preventing the steel strands 10 from shifting before pouring concrete.

[0031] Furthermore, a galvanized metal corrugated pipe 11 is fixedly arranged inside the spiral stirrup 5 below the outer surface of the anchor plate body 1, and the galvanized metal corrugated pipe 11 covers the outside of the steel strands 10.

[0032] By adopting the above technical solution, the galvanized metal corrugated pipe 11 covers the surface of the steel strands 10, which can effectively avoid large-area corrosion of the steel strands 10 by moisture, thereby prolonging the service life of the steel strands 10 and extending the service duration of the anchorage of the anchor plate body 1.

[0033] Working principle: When using this rigid anchoring structure of the anchor plate, first, the steel strand 10 penetrates and inserts into the through-hole 7 inside the sinking groove 6, and then the through-hole 7 of the anchor ring 8 is sleeved on the surface of the steel strand 10. After adjusting the insertion depth of the steel strand 10, the wedge-shaped clamp 9 is inserted into the through-hole 7 of the anchor ring 8. With the extrusion of the through-hole 7, the wedge-shaped clamp 9 clamps the steel strand 10 and tightly fixes it at the fixed position of the through-hole 7. Then, the spiral reinforcement 5, the steel strand 10, and the galvanized metal corrugated pipe 11 can be inserted into the hole of the concrete. At this time, the anchor plate main body 1 fits on the concrete surface, and the positioning reinforcement 3 is inserted into the concrete through the installation hole 2. The "L"-shaped bent part at the front end of the positioning reinforcement 3 is closely attached to the anchor plate main body 1, so that the anchor plate main body 1 can be pre-positioned and closely attached to the concrete surface, thereby improving the fitting tightness. When the anchor plate main body 1 is subsequently pushed to squeeze the concrete and sink, it can also provide guidance for the anchor plate main body 1. The spiral reinforcement 5 is inserted into the hole pre-opened inside the concrete. With its shape, it has a certain elastic force and can provide pre-installation stress for the anchor plate main body 1. When the anchor plate main body 1 sinks, it will squeeze the spiral reinforcement 5 to contract. Concrete is poured into the hole through the grouting pipe 4 to fix the extrusion shrinkage amount of the spiral reinforcement 5, so that it can adapt to the expansion stress of the concrete, making the anchor plate main body 1 more stable after sinking and fixing, effectively adapting to the later thermal expansion and contraction of the concrete, and avoiding the situation that the concrete cracks due to the extrusion of the anchor plate main body 1 and the deformed concrete. Multiple steel strands 10 form multiple support points in the concrete hole. After pouring concrete inside the hole, the steel strands 10 can be integrated with the concrete to provide the tensile force for rigid fixation of the anchor plate main body 1, effectively preventing the anchor plate main body 1 from falling off. The galvanized metal corrugated pipe 11 is coated on the surface of the steel strand 10, which can effectively avoid the large-area corrosion of the steel strand 10 by moisture, thereby increasing the service life of the steel strand 10 and extending the service duration of the anchoring of the anchor plate main body 1. After the anchor plate main body 1 sinks, fill the sunken position with concrete. This is the working principle of this rigid anchoring structure of the anchor plate.
