Abstract
The utility model discloses a wall connecting piece which comprises an embedded bolt, a bolt sleeve, a steel tube and a steel plate, wherein threads are formed in the first end of the embedded bolt; a first side surface of the steel plate is welded at one end of the steel tube, a bolt is welded on a second side surface of the steel plate, and threads are formed in the bolt; and two sections of threads are formed in the inner wall of the bolt sleeve and matched and screwed with the threads of the embedded bolt and the threads of the bolt respectively. The wall connecting piece has the advantages as follows: the rigidity is good, the embedded position is accurate, the wall connecting piece doesn't occupy the position of a rebar when embedded, the disassembly is convenient, holes and plugs are not required to be reserved, the hidden danger of water leakage of the outer wall is avoided, the workload is small, and the cost is low.
Description
Technical field
The utility model belongs to building unit manufacturing technology field, is specifically related to a kind ofly in house building course, is connected the wall-connecting piece of use between external scaffolding and building.
Background technology
In building building construction process, due to factors such as outer-wall building and finishing, security maintenances, need to set up interim external scaffolding.At present, general external scaffolding adopts fastener type steel pipe to set up more, for guaranteeing that external scaffolding is reliably connected with building, resist the effect of wind load, prevent that external scaffolding from collapsing, need to wall-connecting piece be set by relevant specification, according to relevant specification, wall-connecting piece and building require to be rigidly connected, conventional way is when concrete floor is built at present, pre-buried vertical (being vertical) short steel pipes in position, on pre-buried vertical steel tube, reveal about 200mm, between vertical steel tube and external scaffolding, adopt horizontal steel tube to be connected, between horizontal steel tube and vertical steel tube, by steel tube fastener, be connected.The advantage of the method is that good rigidly, burial place are accurate, and that weak point is cost is high, dismounting trouble, tie up reinforcement location when pre-buried, Liu She hole, vertical short steel pipes position that must be to wall-connecting piece when building block exterior wall, after removing, wall-connecting piece adopt fine-stone concrete to carry out shutoff, yet, to the shutoff at hole as slightly imprudent, to cause hole to mend leakiness, thereby to external wall waterproof, leave the hidden danger that is difficult to make up.
Summary of the invention
For above problem, the utility model discloses a kind of wall-connecting piece.
The utility model is taked following technical scheme: a kind of wall-connecting piece, comprise pre-embedded bolt, bolt sleeve, steel pipe and steel plate, and the first end of pre-embedded bolt forms thread; The first side of one end welding steel of steel pipe, a bolt is welded in the second side of steel plate, and bolt forms thread; The inwall of bolt sleeve forms two sections of threads, and two sections of threads of bolt sleeve are spirally connected, the thread of bolt is suitable with the thread of pre-embedded bolt respectively.
Preferably, the second end of pre-embedded bolt was rolled over 90 degree.
Preferably, the middle part outer wall of bolt sleeve forms a circle groove.
Preferably, the thread of pre-embedded bolt is positive tooth, and the thread of bolt is anti-tooth.
Preferably, steel plate is rounded, and the diameter of steel plate is greater than the diameter of steel pipe.
The advantage that wall-connecting piece of the present utility model has is: good rigidly, burial place do not tie up reinforcement location, convenient disassembly and when building exterior wall by laying bricks or stones, do not need to stay to establish hole and shutoff when accurate, pre-buried, has avoided the hidden danger of external wall seepage, workload is few, cost is low.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION figure of a kind of embodiment.
Fig. 2 is the elevation of wall-connecting piece shown in Fig. 1 under use state.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated.
Referring to Fig. 1,2, the present embodiment wall-connecting piece comprises pre-embedded bolt 1, bolt sleeve 2, steel pipe 3, the public thread of one end outer formation of 1 ?1 of pre-embedded bolt 1, and the other end 1 ?2 rolled over 90 degree.One end 3 of steel pipe 3 ?1 end face weld a steel plate 4, this steel plate 4 is rounded, its diameter is greater than the diameter of steel pipe 3, steel pipe 3 forms a lap welding with steel plate 4 by welding and stitches 5.
One end face of the another side weld bolt 6 of steel plate 4, forms a lap welding seam 7 by welding between the two, and bolt 6 forms thread, and this thread is anti-tooth.
The inwall of bolt sleeve 2 form two sections of female threads 2 ?1, respectively with the public thread 1 of pre-embedded bolt ?1, the thread of bolt 6 is suitable and be spirally connected.The middle part outer wall of bolt sleeve 2 form a circle groove 2 ?2, the operation of being convenient to spin.
Referring to Fig. 2; when floorslab concrete template is installed; as requested; horizontally in precalculated position bury bolt 1 underground, and the threaded section 1 of bolt ?1 adopt cement paper or plastic sheeting protection, then concreting; build and form concrete beam plate 8; now, the part of bolt 1 (band bending termination) section within concrete beam plate 8, with threaded section 1 ?1 outside concrete beam plate 8 and perpendicular to the lateral surface of concrete beam plate 8.During installation, first, with bolt sleeve 2 spin bolt 1 and bolt 6, steel pipe 3 is connected securely with pre-embedded bolt 1, finally 9, steel pipe 3 and scaffold is fixedly connected with by fastener 10.
Those of ordinary skill in the art will be appreciated that; above embodiment is only for the utility model is described but not as to restriction of the present utility model; as long as in scope of the present utility model, to the variation of above embodiment, distortion, all will fall into protection domain of the present utility model.
