Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a double-cut earthquake-resistant anchor bolt. Background Technology

[0002] Anchor bolts are a general term for all post-anchoring components, covering a wide range. By embedding anchor bolts into the wall, the entire wall is reinforced. As tension members that penetrate deep into the strata and wall, anchor bolts are divided into various types according to different application scenarios as technology continues to develop. Among them are double-faced seismic anchor bolts. Double-faced seismic anchor bolts are mainly composed of a threaded rod, a bolt, a sleeve, and a locking key. By rotating the bolt, the depth of the threaded rod inserted into the wall is adjusted, and the end of the threaded rod compresses the locking key to achieve locking and reinforcement of the anchor bolt end.

[0003] Existing double-faced seismic anchors can be stably embedded in the wall. However, in actual use, due to the vibration of the wall and the ground, the bolt position is prone to shift, which changes the compression effect of the locking key and affects the stability of the double-faced seismic anchor itself during use. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A double-cut seismic-resistant anchor bolt includes a screw rod, a base, and a push rod. The base is located below the screw rod, and the push rod is installed at the bottom of the screw rod. The push rod is located below the base. An extrusion mechanism is provided outside the push rod to enhance the stability of the connection between the wall and the anchor bolt. The extrusion mechanism includes an embedding component and an anti-retraction component. The embedding component is installed outside the push rod and makes extrusion contact with the wall. The anti-retraction component is installed inside the embedding component and supports and locks the position of the push rod.

[0007] As a preferred technical solution of this utility model, the embedded component includes an outer sleeve, a locking key body, and a compression arc plate. The outer sleeve is installed at the bottom end of the pushing rod, and the locking key bodies are installed at equal intervals at the bottom end of the outer sleeve. There is a gap between each group of locking key bodies. The pushing rod compresses the locking key body to drive the locking key body to press against the wall. The spacing can help the locking key body to deflect stably. The outer sleeve has symmetrically opened slots on its side wall. The compression arc plate is installed on the inner wall of the outer sleeve and on the side of the slot. The compression plate is installed on the compression arc plate and presses against the wall after passing through the slot.

[0008] As a preferred technical solution of this utility model, the extrusion plate is a trapezoidal structure, and the bottom end of the extrusion plate is embedded in the wall to prevent the extrusion mechanism from retracting outside the pushing rod.

[0009] As a preferred technical solution of this utility model, the anti-reverse component includes a mounting plate and a locking block. The mounting plate is symmetrically installed on the inner wall of the outer sleeve. The mounting plate is connected to the extrusion arc plate. The locking block is installed on the mounting plate and supports and limits the position of the push rod.

[0010] As a preferred technical solution of this utility model, the pushing rod includes a connecting column, a connecting rod and an extrusion seat. The connecting column is installed at the bottom end of the screw member. A sleeve is sleeved on the outside of the connecting column and connected to the outer sleeve. A connecting rod is installed at the bottom end of the connecting column. An extrusion seat for extruding the key body is installed at the end of the connecting rod. An extrusion end for extruding and pushing the extrusion arc plate is installed on the outside of the connecting rod. Both the extrusion end and the extrusion seat are conical structures.

[0011] As a preferred technical solution of this utility model, the locking block is in contact with the extrusion end. After the extrusion end extrudes the extrusion arc plate, the top end of the locking block fits with the bottom end of the extrusion end to lock the position of the extrusion end.

[0012] As a preferred technical solution of this utility model, the screw component includes a screw body, a compression nut and a washer. The screw body is installed on the top of the push rod, the compression nut is threaded on the outside of the screw body, and the washer is sleeved on the outside of the screw body and is located below the compression nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, a pressing mechanism and a pushing rod are provided. The screw rod itself drives the pushing rod to move towards the base. At this time, the pressing end and pressing seat on the outside of the pushing rod press the pressing arc plate and the locking key body respectively, causing the locking key body and the pressing plate on the pressing arc plate to press against the inner wall of the wall, further locking the position of the anchor bolt. The setting of the locking block locks the position of the pushing rod and the screw rod, ensuring the stability of the anchor bolt during use and preventing the screw rod and the pushing rod from retracting during use.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0023] like Figure 1 and Figure 2 As shown, this is a structural schematic diagram of the double-faced seismic-resistant anchor bolt in this embodiment. During use, the double-faced seismic-resistant anchor bolt locks and reinforces the position of the sleeve portion to prevent vibration from causing the screw to misalign from the sleeve and thus the bolt to fall off. The double-faced seismic-resistant anchor bolt includes a screw member 1, a base 2, and a push rod 3. The push rod 3 is installed at the bottom of the screw member 1. The base 2 is provided between the screw member 1 and the push rod 3, and it adheres to the wall surface, separating the screw member 1 and the push rod 3 and providing support for their installation. The push rod 3 can compress the wall interior as the screw member 1 rotates to lock the overall position of the anchor bolt. A compression mechanism 4 is provided outside the push rod 3 to enhance the friction between the anchor bolt and the inner wall of the wall.

[0024] As attached Figure 3 As shown, this is a structural schematic diagram of the screw component 1 in this embodiment. The screw component 1 includes a screw body 11, a compression nut 12, and a washer 13. The screw body 11 is installed on the top of the push rod 3. The compression nut 12 is threaded on the outside of the screw body 11, and the washer 13 is sleeved on the outside of the screw body 11. The washer 13 is located below the compression nut 12 and contacts the surface of the base 2. By rotating the compression nut 12, the compression nut 12 moves along the thread on the outside of the screw body 11. With the cooperation of the washer 13, the compression nut 12 is stably attached to the surface of the base 2. When the compression nut 12 rotates, it drives the screw body 11 to move outward, which facilitates the subsequent use of the push rod 3 and enhances the stability of the screw component 1, the base 2, and the push rod 3 during use.

[0025] As attached Figure 3As shown, this is a schematic diagram of the structure of the pushing rod 3 in this embodiment. The pushing rod 3 includes a connecting column 31, a connecting rod 32, and an extrusion seat 33. The connecting column 31 is installed at the bottom end of the screw body 11. The connecting rod 32 is installed at the bottom end of the connecting column 31. The extrusion seat 33 is installed at the bottom end of the connecting rod 32. The extrusion seat 33 is a conical structure, and its radius is larger than that of the connecting rod 32. An extrusion end 34 is installed on the outside of the connecting rod 32. The extrusion end 34 is a conical mechanism, and its radius is larger than that of the connecting rod 32 but smaller than that of the extrusion seat 33. By rotating the screw body 11 itself, the connecting column 31 is driven to move outward under the drive of the screw body 11, providing power for the movement of the extrusion seat 33. A sleeve 35 is installed on the outside of the connecting column 31. The movement of the extrusion seat 33 pushes the sleeve 35 and the extrusion mechanism 4 as a whole, causing the extrusion mechanism 4 to deform itself and assisting the stable operation of the extrusion mechanism 4.

[0026] As attached Figure 4 and Figure 5 As shown, this is a schematic diagram of the extrusion mechanism 4 in this embodiment. The extrusion mechanism 4 includes an outer sleeve 41, a locking key body 42, and an extrusion arc plate 43. An outer sleeve 41 is provided outside the pushing rod 3. Locking key bodies 42 are installed at equal intervals at the bottom of the outer sleeve 41, with a gap between them. When the extrusion seat 33 moves outward under the rotation of the screw body 11, the extrusion seat 33 extrudes the inner wall of the locking key body 42, causing the locking key body 42 to deflect towards the side closer to the inner wall of the wall, so that the edge of the locking key body 42 is embedded into the wall, strengthening the stability of the overall connection between the anchor bolt and the wall. A symmetrical locking groove is provided on the side wall of the outer sleeve 41. An extrusion arc plate 43 is installed on the inner wall of the outer sleeve 41 and located on the side of the locking groove. An extrusion plate 44 is installed on the wall, passing through the locking groove and making extrusion contact with the wall. As the position of the extrusion seat 33 moves, the extrusion end 34 extrudes the extrusion arc plate 43, causing the extrusion arc plate 43 to deform itself and extrude the extrusion plate 44 into the inner wall. During an earthquake, the structure and shape of the extrusion plate 44 prevent the extrusion mechanism 4 and the push rod 3 from sliding down as a whole. An installation plate 45 is installed at the bottom of the extrusion arc plate 43. A locking block 46 is installed on the side wall of the installation plate 45 to block and limit the bottom of the extrusion end 34. The locking block 46 supports the bottom of the extrusion end 34 and prevents the screw body 11 from loosening and falling down from the inside of the push rod 3, thus ensuring the stability of the extrusion mechanism 4 when the anchor bolt is in use.

[0027] In this embodiment, the outer sleeve 41, the locking key body 42, the extrusion arc plate 43 and the extrusion plate 44 form an embedding assembly embedded in the wall, and the mounting plate 45 and the locking block 46 form an anti-retraction assembly.

[0028] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
