Abstract
The utility model discloses a kind of outrigger wall-connecting piece, described wall-connecting piece is placed between scaffold and construction wall, for connecting pin hand cradle and construction wall, it comprises horizontally set and the screw rod that is fixedly connected with wall connecting rod of wall connecting rod, wherein one end of being fixedly connected with scaffold upright rod, the installing hole of a transverse direction is provided with in construction wall, in installing hole, be provided with one for being socketed expansion bolt in screw rod, the expansion sleeve of described interior expansion bolt is connected with screw flight; The lateral length of described installing hole is more than or equal to the lateral length of interior expansion bolt.The outrigger wall-connecting piece that the utility model obtains has that structure is simple, installation and removal are convenient, effectively can improve the quality of masonry.
Description
Technical field
The utility model relates to a kind of construction work connector field, particularly a kind of outrigger wall-connecting piece.
Background technology
Wall-connecting piece refers to the component of connecting pin hand cradle and building, is the important component part of scaffold.Rigid connecting tube refers to the wall-connecting piece adopting steel pipe, fastener or built-in fitting composition, but the way of not concrete regulation rigid connecting tube in specification, causing the way of current various places rigid connecting tube to differ, there is potential safety hazard in part way.
The method of embedded steel tube is wall-connecting piece way the most conventional at present, can play the effect of being rigidly connected.Its specific practice is embedded in about 20cm in beam with a vertical short steel pipes before concrete placings, exposes beam and to break an agreement 20cm, after concrete placings completes, connects the long steel pipe of level and pre-buried vertical short steel pipes by fastener.
The method has following shortcoming: embedded steel tube is not quick detachable, and cause steel pipe to waste, cost is high; Masonry is wall-connecting piece reserving hole, fill up the progress that reserved hole delays follow-up work, and the aperture of reserving hole and hole depth is all larger, after later stage applying mortar, easily forms crack.
Summary of the invention
The purpose of this utility model is the defect in order to solve existing for existing wall-connecting piece, and a kind of outrigger wall-connecting piece provided, this outrigger wall-connecting piece mounts and dismounts all more for convenience, and cost is low.
To achieve these goals, outrigger wall-connecting piece designed by the utility model, described wall-connecting piece is placed between scaffold and construction wall, for connecting pin hand cradle and construction wall, it comprises horizontally set and the screw rod that is fixedly connected with wall connecting rod of wall connecting rod, wherein one end of being fixedly connected with scaffold upright rod, in construction wall, be provided with the installing hole of a transverse direction, in installing hole, be provided with one for being socketed expansion bolt in screw rod, the expansion sleeve of described interior expansion bolt is connected with screw flight; The lateral length of described installing hole is more than or equal to the lateral length of interior expansion bolt.
Further, described screw rod is placed in below or the top of wall connecting rod, and has one section with wall connecting rod by being welded to connect, and the length of its welding section at least should be 1/3 of screw rod total length.This connected mode, can increase the connection area of wall connecting rod and screw rod, and what wall connecting rod was connected with screw rod is more firm, improves the security performance of whole wall-connecting piece.
Compared with prior art, the outrigger wall-connecting piece tool that the utility model obtains has the following advantages:
1, structure is simple, easy for installation: during installation, only need get out installing hole by electric drill in relevant position, then interior expansion bolt be put into installing hole, and be inserted in by the screw rod welded with wall connecting rod in the expansion sleeve of interior expansion bolt, then tighten.
2, when secondary is constructed, only need rotary screw, screw rod is pulled down.During workman's applying mortar, need not dilating screw be pulled down, directly construct, not only decrease the process of secondary construction, effectively raise construction speed, simultaneously, hole on body of wall is also less, can not impact, effectively can improve workmanship to masonry quality and waterproof quality.
Accompanying drawing explanation
Fig. 1 is the concrete structure schematic diagram of wall-connecting piece in embodiment.
In figure: wall connecting rod 1, screw rod 2, installing hole 3, interior expansion bolt 4.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
The outrigger wall-connecting piece that the present embodiment provides, as shown in Figure 1, described wall-connecting piece is placed between scaffold and construction wall, for connecting pin hand cradle and construction wall, it comprises horizontally set and the screw rod 2 that is fixedly connected with wall connecting rod 1 of wall connecting rod 1, wherein one end of being fixedly connected with scaffold upright rod, in construction wall, be provided with the installing hole 3 of a transverse direction, in installing hole 3, be provided with one for being socketed expansion bolt 4 in screw rod 2, the expansion sleeve of described interior expansion bolt 4 is threaded with screw rod 2; The lateral length of described installing hole 3 is more than or equal to the lateral length of interior expansion bolt 4.
In the present embodiment, screw rod 2 is placed in below or the top of wall connecting rod 1, and has one section with wall connecting rod 1 by being welded to connect, and the length of its welding section should be at least 1/3 of screw rod 2 total length.When welding, can adopt double welding, also can adopt one side welding, during one side welding, its weld length should be 2 times of double welding weld length.
The long 50mm of interior expansion bolt 4 in the present embodiment, internal thread 12mm, outer silk 16mm; Screw rod 2 diameter is 12mm, long 400mm, and welding procedure is double welding, and weld length is 60mm.
In the specific implementation, can on screw rod 2, screw rod 2 arranges a packing ring with expansion bolt 4 joint.The surface of expansion bolt 4 in scratch when the Area of bearing that the arranging of packing ring can increase expansion bolt 4 is to reduce the pressure of contact position and to avoid tightening screw rod 2.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
