[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a wind-resistant anchor assembly for assembled buildings, comprising an anchor body, an active part 2 and a driven part 7. The anchor body comprises a bare rod section 1 and a threaded section 6. The outer ring of one end of the bare rod section 1 is fixedly connected with an extrusion head 8, the other end of the bare rod section 1 is fixedly connected with the threaded section 6, and the outer ring of the threaded section 6 is threadedly connected with a nut 5. When the anchor assembly is in use, the nut 5 can be used to limit the anchor assembly, thereby improving the reliability of the connection between the anchor assembly and the assembled building.

[0024] The outer ring of the anchor body is movably connected with an active part 2 and a driven part 7, the driven part 7 is located between the active part 2 and the extrusion head 8, and the driven part 7 is movably connected to the light rod section 1, the inner diameter of the driven part 7 is smaller than the outer diameter of the extrusion head 8, and the extrusion head 8 can limit the driven part 7 to prevent the driven part 7 from being separated from the light rod section 1, the end of the active part 2 close to the expansion head 4 is movably connected to the light rod section 1, the extrusion head 8 can limit the end of the active part 2 close to the expansion head 4, the other end of the active part 2 is movably connected to the threaded section 6, and the threaded section 6 can limit the end of the active part 2 close to the expansion head 4, so that the active part 2 cannot be separated from the anchor body, and then the active part 2 can limit the driven part 7. It can be seen from the above description that the anchor body, the active part 2 and the driven part 7 can form a whole and cannot be separated, which is convenient for the storage of the anchor assembly.

[0025] An expansion head 4 is fixed to one end of the active part 2 and the driven part 7 close to the extrusion head 8, and another extrusion head 8 is fixedly connected to the other end of the driven part 7. When the expansion head 4 is close to the extrusion head 8 under the action of external force, the extrusion head 8 can limit the expansion head 4, and the key piece of the expansion head 4 opens to make the expansion head 4 in an expanded state, thereby improving the firmness of the fixation between the anchor bolt and the anchor hole, and the provision of multiple expansion heads increases the anchoring effect of the anchor bolt, thereby improving the wind resistance of the anchor bolt assembly.

[0026] A medicine tube 9 is provided between the extrusion head 8 and the expansion head 4. The medicine tube 9 is fixedly connected to the bare rod section 1. Chemical reagents are loaded in the medicine tube 9. The chemical reagents are prior art and will not be described here. When the expansion head 4 squeezes the extrusion head 8, the medicine tube 9 will rupture first, and the medicine in the medicine tube 9 will be discharged. The chemical reagent is used to fix the anchor bolt assembly and the anchor hole together, thereby improving the firmness of the connection between the anchor bolt assembly and the anchor hole.

[0027] The extrusion head 8 is a conical structure, the outer diameter of the end of the extrusion head 8 close to the expansion head 4 is smaller than the outer diameter of the other end, and the outer diameter of the end of the extrusion head 8 away from the expansion head 4 is the same as the outer diameter of the driven part 7, and the outer diameters of the active part 2, the driven part 7 and the medicine tube 9 are all the same. This arrangement makes it easier to put the anchor assembly into the anchor hole.

[0028] From the above description, it can be seen that when the anchor bolt assembly is in use, the step of installing the chemical tube 9 is omitted, which can improve the installation efficiency of the anchor bolt assembly, and the chemical agent in the chemical tube 9 can connect the active part 2, the driven part 7, the anchor hole and the anchor bolt body together, thereby improving the reliability of the anchor bolt assembly when in use.

[0029] The other end of the active part 2 is fixedly connected with a gasket 3, the outer diameter of which is larger than that of the active part 2. The outer diameter of the gasket 3 can be designed according to the requirements, and no limit is made here. When the anchor assembly is installed, the gasket 3 can be used to block the anchor hole to prevent the chemical reagent in the anchor hole from flowing out, and the step of installing the gasket 3 is omitted, thereby improving the installation efficiency of the anchor assembly and preventing the gasket 3 from being lost. An anti-skid gasket is fixed to one end of the gasket 3 close to the active part 2. The material of the anti-skid gasket can be rubber. By setting the anti-skid gasket, the sealing between the gasket 3 and the assembled building can be increased, so that the gasket 3 can seal the chemical reagent.

[0030] The other end of the gasket 3 is evenly provided with limiting grooves, and a second medicine tube 11 is fixed on the inner wall of the limiting groove. The second medicine tube 11 is filled with chemical reagents, and both ends of the nut 5 are movably connected with limiting nails 10, and the limiting nails 10 are clamped with the limiting grooves. Through the setting of the limiting nails 10, the nut 5 and the gasket 3 can be connected together by using the limiting nails 10. The limiting nails 10 limit the nut 5 to prevent the nut 5 from loosening when the bolt assembly is in use, thereby improving the use effect of the bolt assembly, and when the limiting nails 10 are screwed into the limiting groove, the limiting nails 10 can squeeze the second medicine tube 11, and the chemical reagent in the second medicine tube 11 can flow out, fixing the gasket 3 and the nut 5, and further improving the firmness of the connection between the nut 5 and the gasket 3.

[0031] To sum up: when the wind-resistant anchor bolt assembly for prefabricated buildings is used, the user puts the anchor bolt assembly into the anchor hole opened on the building during assembly, squeezes the gasket 3, and the gasket 3 drives the active part 2 to move, and the active part 2 can squeeze the driven part 7, and in the squeezing process, the chemical tube 9 breaks first, and the chemical agent in the chemical tube 9 can flow out, and the outflowing chemical agent fills the active part 2, the driven part 7, the anchor hole and the anchor bolt body, so that the active part 2, the driven part 7, the anchor hole and the anchor bolt body can be connected together around, and the expansion head 4 continues to move, so that the extrusion head 8 limits the expansion head 4, and the key sheet of the expansion head 4 can be opened, so that the expansion head 4 is in an expanded state, increasing the contact area between the anchor bolt assembly and the anchor hole, and after the anchor bolt assembly is fixed to the building during assembly with the nut 5, the limiting nail 10 is squeezed to insert the limiting nail 10 into the limiting groove, and the nut 5 is limited by the limiting nail 10 to prevent the nut 5 from loosening.

[0032] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
