Abstract
The utility model relates to a concrete formwork split screw, in particular to a novel water-sealing screw which solves the problems that an existing split screw for fixing a formwork is inconvenient to use, low in efficiency and the like. The novel water-sealing screw structurally comprises a middle steel tube, a water-sealing rubber strip is arranged in the middle of the steel tube, connection screws are arranged at two ends of the steel tube, and a blocking plate and a limit nut are arranged on each connection screw. The novel water-sealing screw facilitates die assembly, outer rods at two ends of the water-sealing screw can be freely dismounted and repeatedly used, and the outer rods can be recycled by factories after being used to save cost.
Description
Technical field
The utility model relates to a kind of concrete blinding Screw arbor with nut at both-ends, is specially a kind of Novel water-stop screw rod.
Background technology
Along with the development of society, the anxiety of building land.Society more and more tends to high level to the requirement of building, and most of building is equipped with basement.In the cast-in-place waterproof concrete construction of outer wall of basement, the hole that the screw rod that uses for reinforcing template stays is a place that seepage very easily occurs, although the basement wallboard can be done external wall waterproof after removing, but the seepage situation is arranged unavoidably still, if do not do sealing piece, water can be along screw rod within the walls infiltration, so sealing up screw has just become the important materials that addresses this problem.
And traditional Screw arbor with nut at both-ends is to weld a square steel sheet to reach the effect of sealing in the middle of common screw.But just because of the sealing steel disc has been arranged so that the workman can not cause construction speed slow by the hole of a hole through the opposite by screw rod as common Screw arbor with nut at both-ends.In concrete casting complete rear pattern plate teardown phase, Screw arbor with nut at both-ends not only can't take out, (general 200mm～300mm) passes template to be exposed at the screw rod of body of wall both sides outward, increased the dismounting difficulty of template, strengthened the active loss of template, exposed parts need to use the gas cutting excision, and the screw rod under the cutting has become waste material, waste great deal of steel, and increased manually, increased construction cost.
Summary of the invention
The utility model uses inconvenience for the Screw arbor with nut at both-ends that solves existing fixed form, and the problems such as inefficiency provide a kind of Novel water-stop screw rod.
The technical solution of the utility model is, a kind of Novel water-stop screw rod, and the steel pipe in the middle of structure comprises, steel pipe is provided with the watertight rubber bar in the middle part, and the steel pipe two ends are provided with connecting screw rod, and connecting screw rod is provided with baffle plate and stop nut.
And Novel water-stop screw rod described in the utility model is the Three-section water stop screw rod, the centre is the in-built water-swellable watertight rubber bar of a steel pipe (length of steel pipe can be processed according to the Thickness Design of wall), the centre is made flat-shaped, and two is square and has impression to be used for the connection of common screw all around.This Novel water-stop screw rod not only makes things convenient for matched moulds, and bar can freely be dismantled, reuse outside the water-proof bolt two ends, can be reclaimed by producer after finishing using, and saves cost.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1-watertight rubber bar, 2-drip ring, 3-steel pipe, 4-sealing card, 5-connecting screw rod, 6-baffle plate, 7-stop nut.
The specific embodiment
As schematically shown in Figure 1, a kind of Novel water-stop screw rod, the steel pipe 3 in the middle of structure comprises, steel pipe is provided with watertight rubber bar 1 in 3 middle parts, and steel pipe 3 two ends are provided with connecting screw rod 5, and connecting screw rod 5 is provided with baffle plate 6 and stop nut 7.
Be provided with drip ring 2, be provided with sealing card 4 at steel pipe 3 two ends in the outside, steel pipe 3 middle parts.
After being used to complete, connecting screw rod 5 and baffle plate 6 and stop nut 7 can be pulled down, re-use, steel pipe 3 is then stayed permanent use the in the body of wall.
