Abstract
The utility model provides an energy-saving water stopping screw. A conical head, a cylindrical connecting head and a polygon connecting head are fixedly connected in sequence to form a conical connecting body, a through hole is formed in the center of the conical connecting body, external threads are arranged at the two ends of a midway screw, the screw sticks into the conical head from the end surface of the polygon connecting head and is fixedly connected with the conical head, the end, sticking into the conical head, of the screw ranges from 1 mm to 10 mm, and the diameter of the screw is nearly the same with the through hole diameter of the conical connecting body. The energy-saving water stopping screw has the advantages that a template is convenient to dismantle, the conical connecting body is capable of being repeatedly used, waste of steel which is cut from the two ends of the water stop screw is avoided every time, steel cost and labor cost are greatly saved for the country in each year, construction efficiency is greatly improved, and a good solution for promoting energy saving and emission reducing is provided for the building material consumption in the country.
Description
Technical field
The utility model relates to a kind of sealing up screw, relates in particular to a kind of energy-saving water-stopping screw rod.
Background technology
Sealing up screw is used for the mixed earth formboard fastening of underground shear wall part pouring, the structure of sealing up screw mostly is screwed stage casing, single two ends screw rod at present, adopt this sealing up screw when needing the sealing up screw two ends by outstanding body of wall both sides to cut off after form removable, thereby ensure the planarization of body of wall, but in practical operation, can not accomplish that sawed-off forms burnishing surface with body of wall, sawed-off two ends screw rod also causes significant wastage, in order to solve the defect of above sealing up screw, adopted afterwards the structure that increases taper gum cover at sealing up screw two ends, although this structure has solved the problem of the outstanding bodies of wall in sealing up screw two ends, but need a large amount of use taper gum covers, and taper gum cover cannot be extracted in body of wall, when construction and inconvenient and forever pollute indoor environment.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-saving water-stopping screw rod, and this sealing up screw is simple in structure, has solved the problem of the outstanding bodies of wall in sealing up screw two ends, and do not use taper gum cover, overall structure is simple, is convenient to dismounting, reusable, greatly reduce the cost of manufacture of sealing up screw.
The utility model is to realize like this, it comprises stage casing screw rod, water stop spacer, conical head, cylindrical connector, polygon connector, outer end screw rod, the center of stage casing screw rod is fixedly connected with water stop spacer, the two ends of the described stage casing screw rod conical head that is threaded, the two ends of described stage casing screw rod are provided with external screw thread, it is characterized in that: conical head, cylindrical connector and polygon connector are fixedly connected sequentially and form taper connection body, this taper connection body center is drilled with through hole, in through hole, be drilled with internal thread, described outer end screw rod extend in conical head and is fixedly connected with from polygon connector end face, the amount that conical head is stretched in the end of outer end screw rod is 1-10mm, the diameter of described outer end screw rod is suitable with the through-hole diameter of taper connection body.
The length of described cylindrical connector is longer than the thickness of template.
The annexation of described outer end screw rod and conical head is preferably riveted fixing.
Technique effect of the present utility model is: simple in structure, easy to use, while using this sealing up screw, surface of wall does not have stage casing screw rod outstanding, because of the thickness that is shorter in length than body of wall of the stage casing screw rod in body of wall, and adopt conical head can facilitate Template Location thickness of wall body mortar leakage prevention simultaneously, adopting polygon connector is in order to become flexible the conical head in body of wall, be convenient to dismounting, reusable, screw rod is extend into the structure in conical head simultaneously, greatly reduce cost of production, not only energy-conservation but also environmental protection, also save a large amount of labor costs, improve the competitiveness of product in market.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Stage casing screw rod 2, water stop spacer 3, conical head 4, cylindrical connector 5, polygon connector 6, outer end screw rod in the drawings, 1.
Detailed description of the invention
As shown in Figure 1, the utility model is to realize like this, the center of stage casing screw rod 1 is fixedly connected with water stop spacer 2, the two ends of described stage casing screw rod 1 conical head 3 that is threaded, conical head 3, cylindrical connector 4 and polygon connector 5 are fixedly connected sequentially and form taper connection body, this taper connection body center is drilled with through hole, the two ends of described stage casing screw rod 1 are provided with external screw thread, described outer end screw rod 6 extend in conical head 3 and is fixedly connected with from polygon connector 5 end faces, the amount that conical head 3 is stretched in the end of outer end screw rod 6 is 1-10mm, the diameter of described outer end screw rod 6 is suitable with the through-hole diameter of taper connection body, the length of described cylindrical connector is greater than the thickness of template.
In the time making this sealing up screw, the two ends of stage casing screw rod are without welding spacer or rubber taper sheath, because outer end screw rod extend in conical head, the length surplus of conical head is just in time the externally threaded length in screw rod end, stage casing, therefore can realize the effect of length location by this structure; Whole outer end screw rod extend in conical head simultaneously and then form an entirety by the mode fixed outer ends screw rod of riveting, such structure greatly reduces cost of production than by the method for machine tooling, there is basement shear wall structure in Yin Meidong building, so the consumption of sealing up screw is very large, thereby reduce great deal of steel waste.
When use, select the length of stage casing screw rod according to thickness of wall body, the two ends of the stage casing screw rod conical head that is threaded, then by corresponding template boring, the diameter in hole is less than the diameter of conical head bottom surface, and screw rod, through this hole, makes template near conical head by this hole, because the major part cross section of conical head is greater than the cross section that template is holed, finally fastening by nut; When the mixed earth of pouring, can mortar leakage prevention, after mixed earth solidifies, by form removable, then by the instrument corresponding with polygon connector, taper connection body is screwed out, make the conical head in body of wall loosening, conical head can be transferred in body of wall.
Claims (3)
