Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and in particular to a non-bonded inverted cone-shaped chemical anchor bolt. Background Technology

[0002] Subway operation generates vibrations and must withstand various external forces, including train loads and passenger loads, while also needing to consider the impact of natural disasters such as earthquakes. Unbonded inverted cone-shaped chemical anchors combine the dual effects of chemical bonding and mechanical locking, offering strong load-bearing capacity and effectively resisting tensile and shear forces.

[0003] Chinese Patent CN222334215U, authorized by the Ministry of Industry and Information Technology, discloses a non-adhesive inverted conical chemical anchor, comprising a conical chemical anchor body assembled on a concrete substrate. The conical chemical anchor body further comprises an inverted conical rod and a threaded rod, with the inverted conical rod fixedly assembled at one end of the threaded rod. An anti-adhesive material is applied to the inverted conical rod and the threaded rod, forming an anti-adhesive layer on their surfaces. An assembly groove is provided on the concrete substrate, and epoxy resin anchoring adhesive is assembled in the assembly groove. The inverted conical rod and the threaded rod are inserted into the epoxy resin anchoring adhesive in the assembly groove. The above-mentioned non-adhesive inverted conical chemical anchor solves the problem of existing inverted conical chemical anchors where the threaded rod easily comes into contact with the epoxy resin anchoring adhesive, causing adhesion between the epoxy resin anchoring adhesive, the threaded rod, and the concrete substrate, making it inconvenient to disassemble the inverted conical chemical anchor later.

[0004] However, the above-mentioned technical solution still has the following shortcomings in practical use. In the process of applying epoxy resin anchoring adhesive, a special injection gun is required. The entire injection process is entirely manual. This not only means that construction personnel must prepare an injection gun separately, increasing the preparation cost and carrying burden, but also makes it difficult to accurately control the amount of anchoring adhesive injected manually. Injecting too much may lead to material waste and may also affect the connection stability between the anchor and the concrete substrate due to adhesive overflow. Injecting too little will not guarantee the bonding strength between the anchor and the concrete substrate, making it difficult to meet the safety requirements of the project. Therefore, we propose an unbonded inverted conical chemical anchor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a non-adhesive inverted conical chemical anchor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-bonded inverted conical chemical anchor, comprising a non-bonded inverted conical chemical anchor and a concrete substrate, wherein an assembly groove is formed on the concrete substrate, a threaded rod is provided at the upper end of the non-bonded inverted conical chemical anchor, an inverted conical rod is provided at the lower end of the non-bonded inverted conical chemical anchor, an installation seat is installed at the bottom end of the inverted conical rod, an assembly screw groove is formed in the middle of the bottom end of the installation seat, a rebar adhesive capsule is provided at the lower end of the installation seat, a threaded interface is installed at the top of the rebar adhesive capsule, the rebar adhesive capsule is filled with rebar adhesive, and multiple sets of extrusion rivets are installed at equal intervals at the bottom end of the installation seat, wherein the non-bonded inverted conical chemical anchor and the rebar adhesive capsule are embedded in the assembly groove on the concrete substrate.

[0007] As an improved technical solution, a positioning ring plate is provided between the threaded rod and the inverted conical rod, and the positioning ring plate has multiple sets of glue discharge holes evenly spaced circumferentially.

[0008] As an improved technical solution, the end of the extrusion rivet has a pointed conical structure.

[0009] As an improved technical solution, the rebar adhesive capsule is a flexible polymer material shell.

[0010] As an improved technical solution, the surface of the inverted conical rod is coated with an anti-sticking layer.

[0011] As an improved technical solution, a sealing gasket is provided on the lower surface of the positioning ring plate.

[0012] As an improved technical solution, the diameter of the positioning ring plate is larger than the inner diameter of the assembly groove.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] I. This utility model assembles a rebar adhesive capsule containing a measured amount of rebar adhesive into the mounting screw groove at the bottom of an unbonded inverted conical chemical anchor. When the unbonded inverted conical chemical anchor is driven into the mounting groove on the concrete substrate, the rebar adhesive capsule is compressed and deformed as the anchor penetrates deeper, and then ruptures under the action of the compression rivet at the bottom of the mounting base. This allows the rebar adhesive inside the capsule to be evenly released into the mounting groove. Therefore, when installing the unbonded inverted conical chemical anchor, there is no need to prepare a separate injection gun, saving additional tool costs and carrying trouble. Furthermore, the amount of rebar adhesive injected can be precisely controlled by the pre-set amount of rebar adhesive in the capsule, ensuring the correct amount of rebar adhesive is used. This improves construction efficiency and reduces construction difficulty while maintaining the connection strength of the unbonded inverted conical chemical anchor.

[0015] II. This utility model uses a positioning ring plate installed between the threaded rod and the inverted conical rod to limit the insertion depth of the anchor bolt, quickly positioning the insertion depth of the unbonded inverted conical chemical anchor bolt, ensuring the load-bearing capacity of the unbonded inverted conical chemical anchor bolt. The glue drain hole on the positioning ring plate can guide the glue liquid to drain outward along the inside of the glue drain hole, thereby avoiding the accumulation of rebar glue on the outside of the assembly groove and improving the bonding uniformity.

[0021] 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.

[0022] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a non-bonded inverted conical chemical anchor includes a non-bonded inverted conical chemical anchor 1 and a concrete substrate 9. An assembly groove 10 is provided on the concrete substrate 9. A threaded rod 2 is provided at the upper end of the non-bonded inverted conical chemical anchor 1, and an inverted conical rod 3 is provided at the lower end of the non-bonded inverted conical chemical anchor 1. An installation seat 4 is installed at the bottom end of the inverted conical rod 3. An assembly screw groove 5 is provided in the middle of the bottom end of the installation seat 4. A rebar adhesive capsule 6 is provided at the lower end of the installation seat 4. A threaded interface 7 is installed at the top of the rebar adhesive capsule 6. The rebar adhesive capsule 6 is filled with rebar adhesive. Multiple sets of extrusion rivets 8 are installed at equal intervals at the bottom end of the installation seat 4. The non-bonded inverted conical chemical anchor 1 and the rebar adhesive capsule 6 are embedded in the assembly groove 10 on the concrete substrate 9.

[0023] By assembling the anchoring adhesive capsule 6 containing a fixed amount of anchoring adhesive into the mounting screw groove 5 at the bottom of the unbonded inverted conical chemical anchor 1, when the unbonded inverted conical chemical anchor 1 is driven into the mounting groove 10 on the concrete substrate 9, the anchoring adhesive capsule 6 will be compressed and deformed as the unbonded inverted conical chemical anchor 1 is driven deeper, and will break under the action of the extrusion rivet 8 at the bottom of the mounting base 4, so that the anchoring adhesive inside the anchoring adhesive capsule 6 is evenly released into the mounting groove 10. This means that when installing the unbonded inverted conical chemical anchor 1, there is no need to prepare a separate injection gun, saving additional tool costs and carrying trouble. At the same time, the amount of anchoring adhesive injected can be precisely controlled by the anchoring adhesive capsule 6, ensuring the amount of anchoring adhesive used. Thus, while ensuring the connection strength of the unbonded inverted conical chemical anchor 1, construction efficiency is improved and construction difficulty is reduced.

[0024] In other embodiments, a positioning ring plate 11 is provided between the threaded rod 2 and the inverted conical rod 3, and the positioning ring plate 11 has multiple sets of glue discharge holes 12 evenly spaced in the circumferential direction;

[0025] A positioning ring plate 11 is installed between the threaded rod 2 and the inverted conical rod 3. This positioning ring plate 11 restricts the insertion depth of the anchor bolt, quickly positioning the insertion depth of the unbonded inverted conical chemical anchor bolt 1 and ensuring its load-bearing capacity. The adhesive drainage hole 12 on the positioning ring plate 11 guides the adhesive to drain outwards along the inside of the drainage hole 12, thus preventing adhesive buildup on the outside of the assembly groove 10 and improving bonding uniformity. Beneficial effects: Prevents localized adhesive buildup, improves bonding uniformity; precise positioning ensures load-bearing capacity.

[0026] In other embodiments, the end of the extrusion rivet 8 is a pointed conical structure;

[0027] With this design, when the unbonded inverted conical chemical anchor 1 drives the anchoring adhesive capsule 6 into the assembly groove 10 on the concrete substrate 9, the subsequent movement of the unbonded inverted conical chemical anchor 1 deforms the anchoring adhesive capsule 6, causing the tip of the anchoring adhesive capsule 6 to contact the extrusion rivet 8. The extrusion rivet 8 then punctures the anchoring adhesive capsule 6, releasing the anchoring adhesive inside. Beneficial effects: Prevents premature leakage of adhesive and ensures precise injection timing.

[0028] In other embodiments, the anchoring adhesive capsule 6 is a flexible polymer material shell;

[0029] This design allows the anchoring adhesive capsule 6 to rupture under the pressure of the extrusion rivet 8, and the broken anchoring adhesive capsule 6 to shrink, allowing the anchoring adhesive inside the anchoring adhesive capsule 6 to be completely released without affecting the mechanical properties of the unbonded inverted cone chemical anchor 1.

[0030] In other embodiments, the surface of the inverted conical rod 3 is coated with an anti-sticking layer;

[0031] This design physically isolates the colloid from the surface of the inverted conical rod 3, leaving only mechanical interlocking, thus facilitating the subsequent disassembly of the unbonded inverted conical chemical anchor 1.

[0032] In other embodiments, a sealing gasket is provided on the lower surface of the positioning ring plate 11;

[0033] With this design, when the unbonded inverted conical chemical anchor 1 is pressed into the assembly groove 10 on the concrete substrate 9, the sealing gasket outside the positioning ring plate 11 can elastically deform and fit tightly against the concrete surface, sealing the assembly groove 10 and preventing the adhesive from overflowing from the port of the assembly groove 10.

[0034] In other embodiments, the diameter of the positioning ring plate 11 is larger than the inner diameter of the assembly groove 10;

[0035] With this design, when the inverted conical rod 3 is inserted into the assembly groove 10, the positioning ring plate 11 can position the insertion depth of the inverted conical rod 3, thereby quickly positioning the position of the unbonded inverted conical chemical anchor 1 and preventing the threaded rod 2 from entering the assembly groove 10.

[0036] This invention provides a non-bonded inverted conical chemical anchor, the specific working principle of which is as follows:

[0037] When using this equipment, first screw the threaded interface 7 on the anchoring adhesive capsule 6 into the assembly groove 5 at the bottom of the unbonded inverted conical chemical anchor 1 to complete the connection between the unbonded inverted conical chemical anchor 1 and the anchoring adhesive capsule 6. Then, use the unbonded inverted conical chemical anchor 1 to drive the anchoring adhesive capsule 6 into the assembly groove 10 on the concrete substrate 9. Then, continue to apply pressure to the unbonded inverted conical chemical anchor 1 to cause the anchoring adhesive capsule 6 to deform against the inner wall of the assembly groove 10, so that the top of the deformed anchoring adhesive capsule 6 contacts the compression rivet at the bottom of the mounting base 4. The rivet 8 punctures the anchoring adhesive capsule 6, releasing the anchoring adhesive pre-stored in the capsule into the concrete substrate 9. This fills the gap between the inverted conical rod 3 and the assembly groove 10, allowing the adhesive to coat the protruding structure of the inverted conical rod 3 and penetrate the concrete pores to form a chemical bond. The anti-adhesive layer prevents the adhesive from adhering to the surface of the inverted conical rod 3, retaining only the mechanical locking function of the inverted conical structure. The assembly groove 10 abuts against the surface of the concrete substrate 9, preventing the unbonded inverted conical chemical anchor 1 from being over-embedded, ensuring that the inverted conical rod 3 is completely inside the concrete substrate 9.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
