Abstract
The invention relates to a rear-mounted rigid wall-connecting device which is characterized in that an angle bar is welded with a steel tube, the two sides of an angle bar area welded with the round steel tube are respectively provided with a round hole, the insides of the two round holes are respectively provided with an expansion bolt, the small head of each expansion bolt passes through each round hole of the angle bar and is arranged inside the angle bar, and the tail part of the large head of each expansion bolt is sleeved with an open tube and is arranged outside the angle bar. Each expansion bolt is beaten into concrete and then firmly screwed, and the tail part of the large head of each expansion bolt is driven to the inside of the open tube so as to expand the tube and then fix each bolt as well as the angle bar on the ground or walls. The rear-mounted rigid wall-connecting device provided by the invention is firm and reliable in structure, easy to operate, and larger in stiffness and endurance. By using the rear-mounted rigid wall-connecting device, a frame body and a constructional engineering structure can be connected effectively, thereby ensuring the overall stability and utilization safety of the frame body.
Description
Technical field
The present invention relates to a kind of rearmounted rigidity wall attaching parts, is the improvement to the conventional rigid wall-connecting piece.For the engineering that built-in fitting (support body tension member) is not set in advance, adopt this rearmounted built-in fitting device effectively support body and building engineering structure to be tied, guarantee support body monolithic stability and safe in utilization.
Background technology
Traditional wall-connecting piece connected mode generally is to adopt built-in fitting is set in advance, at flooring place embedded steel tube, links with connecting wall steel pipe and fastener and vertical rod again, or pre-buried bar dowel, connect the one end perforate of wall steel pipe and be enclosed within on the steel bar end, the other end fastener and vertical rod snapping.Shortcoming: it is suitable for reading that 1, general lacing wire can only be embedded in the collar tie beam or the floor beam of building, be difficult to regulate vertical direction, be difficult to satisfy the requirement of standard about wall-connecting piece " suitable near the host node setting, the distance that departs from host node should be greater than 300mm " and " should be in from bottom first step vertical equity bar and begin setting "; 2, be easy to arbitrarily be removed by the workman; 3, shore and adopt a fastener and scaffold snapping, can not satisfy requirement for bearing capacity sometimes,, influence the current material that reaches of scaffold operating personnel again and transport with two fasteners snapping in inside and outside vertical rod respectively; Gas cutting commonly used is unfavorable for fire prevention when 4, removing.
Summary of the invention
In order to overcome the shortcoming of above-mentioned traditional wall-connecting piece structure, the objective of the invention is to design a kind of rearmounted rigidity wall attaching parts, an end welds angle steel and bore two holes on angle steel on the wall short steel pipes connecting, be fixed on the concrete wall with expansion bolt, the other end is with fastener and vertical rod snapping, thereby reaches sound construction, connects reliably, the purpose of easy construction.
The technical solution used in the present invention:
A kind of rearmounted rigidity wall attaching parts comprises angle steel, steel pipe, expansion bolt, it is characterized in that steel pipe is vertically fixed on the angle steel, and steel pipe one end is connected with angle steel by welding, and the other end is connected with vertical rod by fastener; Be respectively equipped with circular hole in the both sides, angle steel zone that are welded with steel pipe, be inserted in expansion bolt in circular hole, the expansion bolt microcephaly passes the angle steel circular hole and places the inboard of angle steel circular hole, and the big afterbody of expansion bolt puts the opening pipe and places the outside of angle steel circular hole.
The diameter of circular hole is corresponding with the expansion bolt diameter on the described angle steel, the diameter of angle steel circular hole greater than the expansion bolt head diameter less than the diameter of expansion bolt afterbody.
The head little at the expansion bolt diameter is provided with screw thread, and locking nut is housed on screw thread, and the external diameter of tight split nut will be squeezed into the expansion bolt of concrete wall and together lock together with angle steel greater than the diameter of circular hole on the angle steel by locking nut.
Described steel pipe can be divided into the steel pipe or the steel column spare of round steel pipe, rectangular steel tube or random geometry.
During use, expansion bolt is inserted in the angle steel circular hole that is welded with steel pipe, again expansion bolt is squeezed in the concrete wall, tighten the locking nut in the expansion bolt, just wall attaching parts can be securely fixed on the concrete wall, be connected with vertical rod by fastener at steel pipe one end (free end) of wall attaching parts.
Characteristics of the present invention: sound construction of the present invention, be beneficial to operation, have bigger rigidity and holding capacity; This device can bear pulling force can bear pressure again, can effectively support body and building engineering structure be tied, and guarantees support body resistance to overturning and safe in utilization.Simultaneously this wall attaching parts can be made in advance in processing factory, and is easy to process, can reuse the saving cost.
Description of drawings
Fig. 1 is a structural representation of the present invention (lateral view);
Fig. 2 is a front view of the present invention.
The specific embodiment
In Fig. 1～2, on angle steel 1, be welded with steel pipe 2, angle steel is connected by weld seam 5 with steel pipe, have circular hole 3 and circular hole 4 in the steel pipe both sides, in circular hole 3 and circular hole 4, be inserted in expansion bolt 6 respectively, the expansion bolt microcephaly passes the angle steel circular hole and places the circular hole inboard, and the afterbody that expansion bolt is big puts open tube 7 and places the outside of circular hole.During use, expansion bolt is squeezed in the concrete wall, with the angle steel that is welded with steel pipe by circle hole sleeve on expansion bolt, tighten the locking nut 8 in the expansion bolt then, this wall attaching parts is locked on the concrete wall.The free end of wall attaching parts steel pipe is tied support body and building engineering structure by fastener and vertical rod snapping, solid, firm, safety.
