Abstract

A kind of high intensity be the utility model is related to draw piece, belong to heat-preserving building technical field.This is included to drawing nut, from the bolt with washer being screwed into drawing nut one end and from being screwed into the drawing nut other end to draw piece to pull bar, it is described that externally threaded pull bar main body outer end formation and the positioning head of groove matching embedding structure in wallboard side to be hooked are formed with to pull bar, there is the axial limit structure of radial direction abduction between the pull bar main body and positioning head.It is of the present utility model that draw piece has not been conveniently realized only by the embedding structure of positioning head and wallboard and hangs out warming plate, and limit casing need not be worn, positioned using the position limiting structure of itself, therefore easy for construction, positioning is reliably, is advantageous to improve efficiency of construction, ensures construction quality.

Description

A kind of high intensity is to draw piece

Technical field

A kind of fastener is the utility model is related to, especially a kind of high intensity belongs to heat-preserving building construction field to draw piece.

Background technology

Light gauge cold-formed steel shape is assembled into frame structure at the construction field (site), then with precast composite slab combination after-pouring coagulation Soil, it is a kind of new building system that has wide range of applications.Its detailed technical scheme may refer to Application No. 201010574735.7,201020638673.7 and 201020638674.1 Chinese patent literature.

However, so far, this medium-sized steel frame of novel building system, which still uses, is suitable to conventional steel bar concrete knot Structure is fixedly connected to draw piece, and its typical structure sockets part as shown in 201020638674.1 Figure 17, Figure 18（Substantially band The bolt of inlay card head）165 wear limit casing from construction wall side（Packing ring after substantially）80 and through structural steel frame with draw Tight set pipe（Substantially nut）90 threaded connections are fixed, and warming plate is hung over into one side, and opposite side is by tension bolt（Substantially butterfly Forming head bolt）91 are connected with tensing casing threads, and concrete blinding is fixed into another side.

It is this to need when draw piece is installed to wear limit casing therefore not convenient enough, and in order to ensure bonding strength, draw Fitting uses metal material, is unfavorable for ensureing heat-insulating property.

The content of the invention

The purpose of this utility model is：The shortcomings that existing for above-mentioned prior art, propose a kind of easy for construction, installation Reliable high intensity is to draw piece, so as to be advantageous to improve efficiency of construction, ensure construction quality.

In order to achieve the above object, fast-assembling of the present utility model is included to draw piece to drawing nut, to drawing nut one end to twist The bolt with washer that enters and to drawing that the nut other end is screwed into pull bar, it is described pull bar to be formed with outside externally threaded pull bar main body End forms the positioning head with groove matching embedding structure in wallboard side to be hooked, and has footpath outside between the pull bar main body and positioning head The axial limit structure of exhibition.

Compared with prior art, draw piece will directly can be worn to pull bar from construction wall side using of the present utility model After crossing structural steel frame, tightened with tightening nut, the embedding structure only by positioning head and wallboard, which has not conveniently realized, incites somebody to action Warming plate is hung out, and need not wear limit casing, is positioned using the position limiting structure of itself, therefore easy for construction, positioning Reliably, be advantageous to improve efficiency of construction, ensure construction quality.

Brief description of the drawings

The utility model is further described below in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of the utility model one embodiment.

Fig. 2 is the dimensional decomposition structure diagram of Fig. 1 embodiments.

Fig. 3 is the metal bolts schematic diagram of Fig. 1 embodiments.

Fig. 4 is Fig. 3 dimensional decomposition structure diagram.

Embodiment

Embodiment one

The high-strength non-metallic of the present embodiment it is non-to wear do not take out it is special to draw piece as depicted in figs. 1 and 2, including injection Shaping it is nonmetallic to drawing nut 3, from the gold with metal washer 2 and major diameter non-metallic gasket 5 to drawing nut one end to be screwed into Belong to bolt 1 and to drawing the injection molded that the other end of nut 3 is screwed into be formed with externally threaded pull bar main body 4- to pull bar 4 to pull bar 4 The glass fibre of elongatedness direction arrangement is accompanied in 1, therefore there is enough tensile strength.Rectangle is formed to the outer end of pull bar 4 to determine Potential head 4-2, positioning head 4-2 two sides respectively have with wallboard side to be hooked groove match setting-in convex tendon 4-4, therefore can realize and The reliable location of wallboard combines.There is the axial limiting disk 4-3 of radial direction abduction between pull bar main body 4-1 and positioning head 4-2.

During construction, as shown in Figure 3 and Figure 4, the high intensity of the present embodiment is to draw piece with spacing disk 4-3 axial limitings from one Side pass through cold-rolled forming section skeleton 6 after, with to draw nut 3 tighten, its outer end by positioning head 4-2 setting-in convex tendon 4-4 and envelope The side groove of the insertion insulation composite shuttering 7 of edge strip 9 makes it be positioned by reliable hook；It is screwed into again by from opposite side to drawing nut 3 Tool-typed formwork 8 is fixed on the opposite side of cold-rolled forming section skeleton 6 by metal bolts 1.

Compared with prior art, the present embodiment is provided with spacing disk directly on to pull bar, eliminates and wears stop collar Pipe, that is, reduce number of parts, save cost, facilitate installation again.Further, since wallboard is not passed to pull bar, thus not Influence decoration of exterior wall；And metal bolts are not formed through structure, thus heat bridge is avoided, heat insulation effect is preferable.

In addition to the implementation, the utility model can also have other embodiment.For example, pull bar is implanted into metal, The high intensity bar core of carbon fiber or glass fibre material, so as to further improve tensile strength.It is all to use equivalent substitution or equivalent The technical scheme formed is converted, all falls within the protection domain of the requires of the utility model.
