Combined anchoring part for buildings

Abstract

The invention relates to the technical field of anchoring parts, and discloses a combined anchoring part for buildings. The combined anchoring part for buildings comprises a fixing plate A and a fixing plate B. The center of the front surface of the fixing plate B is provided with a hole and is sleeved with an insertion shaft, the center of the back surface of the fixing plate A is fixedly connected with an insertion cylinder A, the center of the insertion cylinder A is in a hollow state and is sleeved with an insertion cylinder B, and the fixing plate A is internally provided with a groove and is sleeved with straight gears D, the centers of the back face of the straight gears D are fixedly connected with the center of the front face of the inserting cylinder B. The straight gears D are arranged in the fixing plate A in a sleeved mode, holes are formed in the positions, corresponding to the centers of the four straight gears D, of the back face of the fixing plate A, threaded rods are arranged in the holes in a sleeved mode, and threaded holes are formed in the positions, corresponding to the four straight gears D, of the front face of the fixing plate B. When wallboards are connected, connecting acting force is completely applied to the fixing plate A and the fixing plate B, the problem that the wallboards are abraded and even damaged due to the fact that large pressure generated in connecting process acts on the wallboards is solved, using stability of the wallboards is improved, and service life of the wallboards is prolonged.

Description

technical field [0001] The invention relates to the technical field of anchors, in particular to a combined anchor for construction. Background technique [0002] During building construction, it is necessary to combine wall panels to enhance their thickness or increase performance, and the combination of wall panels requires the use of anchors. [0003] The existing patent number CN108071639B proposes an expansive anchor which can be inserted into the borehole as far as possible by hand and without the use of a hammer or other auxiliary devices, up to the desired anchoring depth, without great effort , this object is solved according to the invention by an expansion anchor with the following features: the outer diameter of the spacer section is smaller than the nominal diameter of the expansion anchor, and the expansion sleeve has an outer diameter in the unexpanded state , the outer diameter is so smaller than the nominal diameter of the expandable anchor that the average...

Problems solved by technology

In particular, the expansion sleeve has slots for this purpose, which divide the expansion sleeve into individual expansion elements. When the above-mentioned anchor is used, it is first necessary to arrange the sleeve on one wall panel and then on the other wall panel. After the holes are opened, the expansion bolts are used to connect and fix the anchors. However, when the above-mentioned anchors are used to fix the wall panels, no matter whether they are sleeves or expansion bolts, they will directly act on the wall panels, which will generate greater pressure on the corresponding wall panels. It is easy to cause damage to the wallboard and affect its service life
