Abstract
The utility model discloses a combination opposite-pulling screw rod, which is characterized in that the middle position of a support bar is sleeved with a waterstop ring. The middle position of the support bar in the wall is provided with the waterstop ring, thus, the combination opposite-pulling screw rod effectively solves the technical problem of leakage prevention of the opposite-pulling screw rod and has obvious waterproof effect. Meanwhile, the junction of the combination opposite-pulling screw rod and the outer wall of the wall is provided with a dismountable extension rod so as to be convenient for disassembly when removing a mold after the wall is subjected to pouring. The dismountable extension rod can be used repeatedly. Therefore, the combination opposite-pulling screw rod saves cost, avoids waste, is economic and practical, has higher popularization and application values and can generate good economic benefit and social benefit.
Description
Technical field
The utility model discloses a kind of Screw arbor with nut at both-ends, a kind of specifically combined type Screw arbor with nut at both-ends belongs to construction engineering technical field.
Background technology
At present, along with the highrise building of China is more and more, concrete wall also generally is used.When the building concrete body of wall is built, need install template in advance, because formwork erection in the body of wall both sides, reaches iron wire all can't satisfy formwork erection to the method for drawing requirement admittedly with one-sided top.Therefore, select the Screw arbor with nut at both-ends of technical feasibility, economical rationality to become the key of concrete wall formwork erection.But Screw arbor with nut at both-ends commonly used need penetrate body of wall when being used for outer wall of basement concreting, occurs leakage problems easily.Simultaneously, Screw arbor with nut at both-ends commonly used mostly is disposable use, in that cutting is unnecessary when exposing screw rod, and the effort of taking a lot of work, and can only reclaim small amounts of waste, cause the waste of constructional materials.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of combined type Screw arbor with nut at both-ends is provided, and waterproof effect is obvious, and detachable extension rod can reuse, and avoids waste, and is economical and practical.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that a kind of combined type Screw arbor with nut at both-ends is with seal ring in the support bar centre position, at the support bar two ends detachable extension rod is set.
Above-mentioned combined type Screw arbor with nut at both-ends, its seal ring are the hydro-expansive rubber seal ring.
Above-mentioned combined type Screw arbor with nut at both-ends, its detachable extension rod is that bolt is connected with support bar.
Combined type Screw arbor with nut at both-ends of the present utility model is provided with a seal ring on the support bar centre position in body of wall, efficiently solve the technical problem of Screw arbor with nut at both-ends antiseep, and waterproof effect is obvious.Simultaneously, in junction detachable extension rod is set with the body of wall outer wall, be convenient to body of wall build finish after dismounting during form removal, dismountable extension rod can be reused, save cost, avoid waste, economical and practical, have higher popularization and application values, can produce good economic benefit and social benefit.
Description of drawings
Fig. 1 is a user mode schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, combined type Screw arbor with nut at both-ends of the present utility model, its support bar 6 is a spindle, the outside, centre position is with hydro-expansive rubber seal ring 1, is fixed with support bar cushion block 3 at the two ends of support bar 6, and support bar cushion block 3 is near two side templates 2, support bar 6 two ends are provided with internal thread, cooperatively interact with the external screw thread of detachable extension rod 4 one ends, be provided with fixing card 5 at the other end of detachable extension rod 4, fixing card 5 is threaded with detachable extension rod 4.
During use, boring on the template 2 now, on template 2, formboard fastening 2 carries out concrete building then with the integral installation of combined type Screw arbor with nut at both-ends, build finish after, template 2 is disassembled, dismantle the detachable extension rod 4 that expose both sides at last.
Certainly, above-mentioned explanation is not to be restriction of the present utility model, and the utility model also is not limited to aforesaid operations, and all variations of making in essential scope of the present utility model, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
