Description

Two formula awl (directly) shape sleeve pipe screw rods

This invention is involved in building operations, two formula awl (directly) shape sleeve pipe screw rods that vertical form work engineering is connected and fixed.

In building operations, the quality of major project is good and poor, and is relevant earnestly with the location of template, and form work engineering location and firmly too busy to get away screw rod.It is related to the major issue of workmanship, safety, economic benefit.And the tired lock of traditional screw rod operation of using at present needs the merit silk, welds three road seal rings, and every will be burnt and cuts four times, and pre-buried wooden sealing sheet is also wanted in the wall both sides, and after the concreting, wooden sealing sheet also will be dug out again, burns when cutting screw rod, and the template of burn is more.The tradition screw rod has not only been wasted the huge financial resources and the talent, and has brought quality problems such as serious environmental pollution, disaster hidden-trouble, body of wall seepage.

Purpose of the present invention just is to solve traditional screw rod existing in prior technology the problems referred to above, and a kind of pollution-free, saving of labor, material-saving, handled easily are provided, definitely guarantee two formulas awl (directly) shape sleeve pipe screw rods of workmanship.

The present invention realizes " two formula awl (directly) shape sleeve pipe screw rod " by following scheme.It is made up of outer bar, interior bar, sleeve pipe, sleeve pipe outer cover etc.By sleeve pipe outer bar is connected with interior bar, by the width of interior bar control template home record.Its each accessory all is designed to two formulas, and each accessory divides several big ting models to satisfy the needs of engineering again.The two formulas of outer bar are designed to circle straight-bar and conical rod, and are little outer for convenience detach greatly in the conical rod, can select conical rod for use at baroque position.The two formulas of interior bar are designed to light round bar and full screw mandrel, and full screw mandrel waterproof is better than the light round bar, should choose full screw mandrel in the waterproof significant points.The sleeve pipe appearance is designed to square and hexagon, can select hexagon for use when needing the super large screw rod, and it is unsuitable excessive that it can control the hole of metope.The sleeve pipe bore design is straight hole and medium-sized half little hole, in order to save material, can select medium-sized half aperture sleeve pipe for use in suitable structure.The design of sleeve pipe outer cover, endoporus can be made according to the sleeve pipe profile, and appearance is designed to conical and circular cone S shape, and the screw rod of super large can be selected circular cone S shape outer cover for use.Two formula awl (directly) shape sleeve pipe screw rods, its each details has all been carried out design meticulously cleverly, can reach the effect of getting twice the result with half the effort.

Succeeding in developing of two formulas awl (directly) shape sleeve pipe screw rods broken all tired operations of locking of traditional old screw rod, eliminated environment pollution, disaster hidden-trouble, common quality defect, obviously improved workmanship and speed.The every cover price cost of two formula awl (directly) shape sleeve pipe screw rods is about 4.30 yuans, and it can have enough to meet the need and reuse more than 20 times, is equivalent to use once save a traditional screw rod.Interior bar of its each only use calculates according to present material valency, and as average long 40cm, every interior bar valency spend less than traditional screw rod burning and cut half money four times, and make template in time be had enough to meet the need utilization about 0.90 yuan.The metope quality can reach the dry wall requirement naturally, and operation is promptly convenient simply again, for operating personnel have created good operating environment.
