Embodiment 1

[0044] Such as figure 1 As shown, the combined structural anchor bolt of this embodiment includes an anchor rod 10, an expansion device 20 and a spring 30. The expansion device 20 is arranged at the front of the anchor rod 10, and There are transverse glue flow grooves 11, longitudinal communication grooves 12 and screw grooves 13. The end face of the front portion of the anchor rod 10 is provided with a glue inlet 14 communicated with the longitudinal glue flow groove 12; the adhesive enters the longitudinal glue flow groove 12 from the glue inlet 14 and is connected with the glue flow groove 12. The expansion device 20 is glued and connected; the front part of the anchor rod 10 is provided with a threaded groove 13 that matches the spiral of the spring 30 . The front end of the spring is provided with a spring ring 15 .

[0045] The transverse glue flow groove 11 and the vertical glue flow groove 12 intersect each other to form a cross glue flow groove, and the transverse ...

Embodiment 2

[0047] A method for using a combined structural anchor bolt, comprising the following steps:

[0048] (1) Pre-open corresponding matching anchor holes on the substrate;

[0049] (2) Screw the spring to the anchor rod to reach the specified position, or adjust the spring extension length according to the actual needs;

[0050] (3) Attach structural adhesive to the front end of the anchor rod and / or inject injection adhesive into the anchor hole;

[0051] (4) Push the combined structural anchor into the anchor hole, and then hammer the end of the structural anchor until the structural anchor reaches the preset position;

[0052] (5) Flatten or scrape off the glue overflowing from the anchor hole, and wait for the structural glue to solidify to form a structure of glue bars.

Abstract

The invention relates to a combined structural anchor bolt. The combined structural anchor bolt comprises an anchor rod and an expansion device. The expansion device is arranged on the front part of the anchor rod. The combined structural anchor bolt further comprises a spring. The front part of the anchor rod is provided with a thread groove spirally matched with the spring. The side face of thefront part of the anchor rod is provided with a transverse glue flowing groove. The anchor rod is provided with a thread matched with the spring, and combined installation is facilitated; and the spring can be adjusted on site according to the length of the thread, and the demands of different glue rib structures are met.

Description

technical field [0001] The invention relates to a combined structural anchor bolt. Background technique [0002] The insulation layer of building walls, curtain walls, and architectural decoration fields such as lamps, plumbing, and communications require post-anchoring technology, and mechanical anchors and chemical anchors are usually used. Mechanical anchors (structural anchors) use mechanical locking or friction with concrete or other objects for anchoring and locking. Commonly used are post-expansion bottom anchors, self-cut bottom anchors, cement self-tapping anchors, and Anka anchors. Bolts, heavy-duty anchors, etc.; chemical anchors usually consist of a threaded rod and an adhesive hose. Then screw the anchor bolt into the anchor hole with a screw tool, and twist the chemical hose through the threaded rod during the screw screw process to achieve the anchoring effect, mainly including high-strength chemical anchor bolts, shaped anchor bolts, inverted cone anchor bol...
