Description

Technical Field

[0001] This utility model relates to the field of chemical anchor technology, specifically a chemical anchor with anchoring function. Background Technology

[0002] Chemical anchors, also known as chemical bolts, are composite components made of chemical agents and metal rods. They are fixed to the concrete substrate by bonding the bolt with a special chemical adhesive to achieve anchoring. Because chemical anchors have a large pull-out bearing capacity, they can replace embedded anchor bars. Therefore, they are often used in situations where steel structure embedded parts are forgotten to be installed on the construction site but the concrete has been poured. They can be used as a remedy for situations where steel structure embedded parts have been forgotten to be installed.

[0003] Chinese utility model patent CN217783972U proposes a "chemical anchor bolt with anchoring function". This technical solution addresses the problem that "existing technologies use soft-pack chemical bags made of aluminum foil as containers for curing agents. In the anchoring process, there is a lack of auxiliary materials, which reduces the bonding force between the anchor bolt and the concrete. Moreover, the current anchoring is only done by adhesive, which reduces the load-bearing capacity of the anchor bolt". The utility model provides the following technical solution: "Using a glass bottle to contain the curing agent and quartz sand, the crushed glass shards can act as fine aggregate to strengthen the bonding force between the chemical anchor bolt and the concrete. The other end of the inverted conical screw is provided with multiple sets of inverted conical components. The inverted conical components make the load transfer more uniform. The high-strength anchoring adhesive and the inverted conical screw slide together to form a keying effect. Moreover, this anchoring method adopts adhesive + key-shaped interlocking to improve the load-bearing capacity."

[0004] The above-mentioned device has the following defects in actual use: after the curing device is placed into the drilled hole of the concrete substrate, the installation of the chemical anchor into the drilled hole of the concrete substrate will break the glass bottle. This can easily push the curing agent and quartz sand inside the glass bottle into the depth of the drilled hole of the concrete substrate, resulting in uneven contact between the curing agent and quartz sand on the outside of the chemical anchor and affecting the bonding effect. Therefore, a new chemical anchor with the function of anchoring is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a chemical anchor with a bolting and anchoring function to overcome the deficiencies of the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A chemical anchor with anchoring function includes a curing device and a chemical anchor inserted into a drilled hole in a concrete substrate. The curing device includes a glass ring, a first glass tube fixedly installed at the bottom of the glass ring, a second glass tube fixedly installed at the bottom of the glass ring and fitted outside the first glass tube, quartz sand filling the space between the first and second glass tubes, and a third glass tube fixedly installed at the bottom of the glass ring and fitted outside the second glass tube, with a curing agent filling the space between the second and third glass tubes.

[0008] The chemical anchor includes three externally threaded arc plates arranged in a circular array. The diameter of the circular array formed by the three externally threaded arc plates is smaller than the inner diameter of the glass ring. Each of the three externally threaded arc plates has an internally threaded groove on its inner side. An externally threaded frustum is provided on the inner side of each of the three externally threaded arc plates. An anchor is fixedly installed on the top of the externally threaded frustum. The diameter of the anchor is larger than the diameter of the circular array formed by the three externally threaded arc plates.

[0009] The beneficial effects of this utility model are as follows: the curing device is inserted into the drilled hole of the concrete substrate, and then three externally threaded arc plates are combined into a ring. The ring is inserted into the glass tube through the glass ring. Then, the externally threaded frustum and the anchor bolt are rotated to penetrate deeper, expand the arc plate and crush the glass tube, so that the curing agent and quartz sand flow out and mix with the glass fragments, which enhances the bonding effect. The mixed curing agent evenly coats the outside of the arc plate and wraps the connection between the anchor bolt and the arc plate through the expanded gap, so as to achieve the purpose of anchoring. The whole process realizes the effective release of curing agent and the formation of anchoring structure, which improves the overall stability and adhesion.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, an external hexagonal head is fixedly installed on the top of the anchor bolt.

[0012] Furthermore, the anchor bolt is externally fitted with a gasket.

[0013] Furthermore, the bottom diameter of the external threaded frustum is smaller than the inner diameter of the annulus formed by the three external threaded arc plates. Attached Figure Description

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1, as Figures 1-5 As shown, a chemical anchor with anchoring function includes a curing device and a chemical anchor inserted into a drilled hole in a concrete substrate. The curing device includes a glass ring 1, a first glass tube 2 fixedly installed at the bottom of the glass ring 1, a second glass tube 3 fixedly installed at the bottom of the glass ring 1 and fitted outside the first glass tube 2, quartz sand filling the space between the first glass tube 2 and the second glass tube 3, and a third glass tube 4 fixedly installed at the bottom of the glass ring 1 and fitted outside the second glass tube 3, with a curing agent filling the space between the second glass tube 3 and the third glass tube 4.

[0023] Specifically, the chemical anchor includes three externally threaded arc plates 5, which are arranged in a circular array. The diameter of the circular array formed by the three externally threaded arc plates 5 is smaller than the inner diameter of the glass ring 1. Each of the three externally threaded arc plates 5 has an internally threaded groove 6 on its inner side. An externally threaded frustum 7 is provided on the inner side of the three externally threaded arc plates 5. An anchor 8 is fixedly installed on the top of the externally threaded frustum 7. The diameter of the anchor 8 is larger than the diameter of the circular array formed by the three externally threaded arc plates 5.

[0024] The working principle of the chemical anchor with bolting and anchoring function provided in this embodiment is as follows:

[0025] Before use, the inside of the drilled hole in the concrete substrate must be thoroughly cleaned to remove debris and dust, ensuring the inner wall is flat and dry. Then, the curing device can be inserted into the drilled hole. Next, the three externally threaded arc plates 5 are combined into a ring and inserted into the first glass tube 2 through the glass ring 1. Then, the externally threaded frustum 7 is rotated and inserted into the ring formed by the three externally threaded arc plates 5. As the externally threaded frustum 7 and the anchor bolt 8 are inserted deeper, the three externally threaded arc plates 5 can be opened, thus crushing the first glass tube 2, the second glass tube 3, and the third glass tube 4. The curing agent filling the space between the second and third glass tubes and the quartz sand between the first and second glass tubes can then flow out. The flowing curing agent and quartz sand mix with the glass fragments to increase the bonding effect. The mixed curing agent can then evenly coat the outside of the three externally threaded arc plates 5. The gaps created by the unfolded three externally threaded arc plates 5 can then wrap around the connection between the anchor bolt 8 and the externally threaded arc plates 5, thus achieving the anchoring effect.

[0026] Example 2, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] An external hexagonal head 9 is fixedly installed on the top of the anchor bolt 8.

[0028] This configuration allows for easy connection between the anchor bolt 8 and the external drilling rig output end via the installed external hexagonal head 9. The external drilling rig can drive the external hexagonal head 9 and the anchor bolt 8 to rotate, which can improve installation efficiency.

[0029] Example 3, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0030] Anchor bolt 8 is externally fitted with a gasket 10.

[0031] This configuration, with the installed shim 10 used to fill the gap between the external hexagonal head 9 and the drilled hole or mounting surface of the concrete substrate, ensures that the anchor bolt can be tightly connected to the mounting surface, preventing loosening and falling off.

[0032] Example 4, as Figures 2-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0033] The bottom diameter of the external threaded frustum 7 is smaller than the inner diameter of the annulus formed by the three external threaded arc plates 5.

[0034] This design makes it easy for the external threaded frustum 7 to be inserted into the ring formed by the three external threaded arc plates 5.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
