Description

A kind of from boring dismountable stress bolt composite member

Technical field

The utility model relates in construction work for fixing accessory, especially a kind of from boring dismountable stress bolt composite member, this composite member mainly comprises bolt and clasp, this utility model is fixed on the steel mesh reinforcement in construction work in template, prevent steel mesh reinforcement drift floating in the time of concreting, simultaneously all right accelerating construction progress, saves installation cost, ensures construction safety.

Background technology

At present, in construction work, steel mesh reinforcement is fixed in template and mostly adopts iron wire to fix, there are following several defects for this form of construction work: first, because iron wire will be fixed reinforcing bar, also to fix reinforcing bar and template simultaneously, and iron wire pulling force is limited, in the time that stretch amplitude is large, iron wire easily ruptures, will increase like this loss, affect construction speed, and to there will be empty button phenomenon (be that surface looks solid that but tying causes half breaking state because of coiling overexertion, when grouting because of concrete buoyancy, can make filling member unbalance, impact construction), its two, iron wire is thinner, pulling force is crossed conference and is penetrated in filling member and damage it, gets loose phenomenon, reduces anti-floating power, its three, in the time of stripping, to cut at twice iron wire---first before stripping, cut once, expose outside also will cutting at the bottom of cement board after stripping screw---the progress of construction is slow like this, paying of increasing manpower, has increased cost of labor, its four, because such construction is no less than two people operations, be subject to the restriction of many factors, can not be control construction speed, its five, due to iron wire construction location disunity, often to reserve longer iron wire, thereby strengthen loss, increase cost, finally, iron wire exists potential safety hazard easily to scratch health and face in the time of construction.

Therefore, for above-mentioned many disadvantages, in order to adapt to the development trend in market, meet people's demand, be badly in need of a kind of new product and occur.

Summary of the invention

For above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of from boring dismountable stress bolt composite member, this utility model can make steel mesh reinforcement well be fixed in template, make it not drift about, can not float, but also can accelerating construction progress, save installation cost, ensure construction safety.

In order to solve the problems of the technologies described above, it is a kind of from boring dismountable stress bolt composite member that the utility model provides, and mainly comprises bolt and latch closure.Wherein, bolt comprises bolt head and screw rod, and bolt head and screw rod are not one, but be threaded connection, that is to say that they can separate, bolt head is made up of three parts, be top, the protuberance of bolt head and the bottom of bolt head of bolt head, the top of bolt head is hexagon, because the cross section of the sleeve of electric drill is also hexagonal, can use like this Electric portable drill to operate bolt; What be connected with the top of bolt head is the protuberance of bolt head, and it can prevent that bolt from coming off from clasp; What be connected with the protuberance of bolt head is the bottom of bolt head, it is a cylinder, there is an an end opening and threaded hole in cylindrical inside, be screw hole and screw-socket, because the screw thread on screw rod is corresponding with the screw thread of screw hole, can facilitate like this bolt head and screw rod to be threaded connection; Screw rod is actually a kind of Self Drilling Screws, formed by screw mandrel and silk tail, silk tail present brill shape of tail, again owing to being bolted to after template, silk a tail can expose template a little, in the time of dismounting template, can on electric drill, load onto socket wrench specially adapted for it like this, to start in the other direction, can easily unload screw, template just can intactly unload, can not damage template, the screw disassembling can be reused; For clasp, it is made up of pulling force hook and ring portion, and wherein the effect of pulling force hook is for hooking reinforcing bar, and ring portion is for blocking bolt, preventing bolt falling.

Concrete operations flow process of the present utility model is as follows:

First reinforcing bar is placed in template, be net structure, one time punching molded hex bolts head and screw combinations, coordinate the clasp of the buckle of high strength elastic force finally to consist of " certainly boring dismountable stress bolt composite member ", according to mechanics principle, the pulling force fastener of clasp in reinforcing bar, utilize electric drill to be enclosed within bolt head, reinforcing bar and template are fixed together, finally reach required pulling force, play anti-floating effect, in the time of dismounting template, unload screw in template bottom with instruments such as electric drills, template just can easily come off, and can not damage template.

Need to illustrate, this bolt combination part is generally taking every square metre three cover or three covers are above is uniformly distributed as benchmark, and reinforcing bar and template are fixed together.

Advantage of the present utility model:

Use this bolt combination part, can reduce template loss largelyr, accelerating construction progress, saves installation cost, ensures construction safety.
