Abstract
The utility model relates to a constructional expansion bolt, comprising an expansion screw, an expansion tube arranged at the outer side of the expansion screw, gaskets, and nuts, the outer end of the expansion screw is provided with a reinforcing bar connected integrally with the expansion screw by butt weld, as using the expansion bolt, the work of positioning and drilling is made on the surface of a concrete column, the expansion bolt is put into the hole, the nut is screwed to expand the expansion bolt, thereby implanting tendons at the connection position between the concrete column and the brick-setting can be achieved. The utility model has good stress function, the electric resistance butt weld is adopted, the welding rod is not used, the cost is low, the construction time can be saved, and the construction quality can be ensured.
Description
Technical field
The utility model relates to a kind of stiffener for building, particularly a kind ofly is used to be arranged on combine with the masonry EXPANSION ANCHOR BOLTS at place of concrete post.
Background technique
The EXPANSION ANCHOR BOLTS of using in the prior art for building, comprise expansive screw, be located at expansion tube, packing ring and the nut in the expansive screw outside, when use combines the place at the concrete post with masonry, elder generation's location drilling on the concrete post, EXPANSION ANCHOR BOLTS is placed the hole, after the swelling, on-the-spot with the reinforcing bar joint welding on EXPANSION ANCHOR BOLTS.The defective that exists is, the field welding amount is big, is easy to generate mass defect, and EXPANSION ANCHOR BOLTS makes the two not on same axis with the reinforcing bar joint welding, and stress performance is poor, and construction quality can not get guarantee.
Summary of the invention
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, propose a kind of stress performance strong be used for combine with the masonry EXPANSION ANCHOR BOLTS at place of concrete post.
Technical problem to be solved in the utility model is to be reached by following technological scheme.The utility model is a kind of EXPANSION ANCHOR BOLTS for building, comprises expansive screw, is located at expansion tube, packing ring and the nut in the expansive screw outside, is characterized in that being provided with the expansive screw butt welding in the outer end of expansive screw is the reinforcing bar of one.Like this, during use, in concrete post surface alignment punching, and EXPANSION ANCHOR BOLTS placed the hole, fastening nut is with the swelling EXPANSION ANCHOR BOLTS, thereby finishes the bar planting that the concrete post combines with masonry and locates.
Technical problem to be solved in the utility model can also further be reached by following technological scheme.Above-described EXPANSION ANCHOR BOLTS is provided with two nuts, like this, can strengthen the swelling degree of EXPANSION ANCHOR BOLTS, prevents the silk mouthful effect of attrition construction quality of single nut.
Compared with prior art, the utility model has the advantages that the stress performance of EXPANSION ANCHOR BOLTS is good, adopt upset butt welding, do not use welding rod, cost is low, and can save the engineering time, and realize batch production production, can in time examine the quality of the production easily, to ensure construction quality.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Embodiment.With reference to accompanying drawing, the utility model is an EXPANSION ANCHOR BOLTS for building, comprise expansive screw 6, be located at expansion tube 1, packing ring 2 and the nut 5 in expansive screw 6 outsides, the EXPANSION ANCHOR BOLTS of present embodiment is provided with two nuts (5,3), being provided with expansive screw 6 upset butt welding in the outer end of expansive screw 6 is the reinforcing bar 4 of one, expansive screw 6 is welded on the same axis with 4 pairs of reinforcing bars, during use, punch in concrete post surface alignment, and EXPANSION ANCHOR BOLTS placed the hole, fastening nut is with the swelling EXPANSION ANCHOR BOLTS, thereby finishes combine with the masonry bar planting at place of concrete post.
Claims (2)
