Abstract
The utility model provides a wall-penetrating water seal screw rod, which has the advantages that the water seal effect is good, and the bearing capacity of a fixed template is large. The wall-penetrating water seal screw rod comprises a sleeve pipe with a depressed part in the middle, internal threads formed at the two ends of the sleeve pipe, a perforated water seal sheet and two sleeve heads positioned at the two ends of the sleeve pipe, wherein the water seal sheet is arranged on the sleeve pipe close to the depressed part. The quantity of the internal threads is nine or more; and each thread has certain inclination.
Description
Technical field
The utility model relates to the building unit technical field, especially relates to a kind of sealing up screw.
Background technology
The in a lot of fields extensive use of impervious concrete is used at most in water conservancy project structure and the basement.In the impervious concrete work progress, after needing to adopt the sealing up screw fixed form, carry out again concrete.Existing sealing up screw, its structure are generally the screw rod that all there is one section screw thread at two ends, anti-skidding set when this section screw thread is reinforcing template; Be provided with a sealing piece in the middle of the screw rod; Screw thread is normally straight, and its screw thread number is few, often is 6-7.In use, stagnant water effect often occurs poor, the fixed form ability to bear is little, uses the problems such as inconvenient.
The utility model content
The utility model has overcome the defects that prior art exists, and provides a kind of stagnant water effect good, the sealing up screw through walls that the fixed form holding capacity is large.
Realize the utility model purpose sealing up screw through walls, comprise a centre with the sleeve pipe of depressed part position, the sleeve pipe two ends are provided with internal thread, a sealing piece with holes, and two are positioned at the pullover of sleeve pipe two ends, and sealing piece is located on the sleeve pipe at close depression position.
Described internal thread quantity is more than 9 or 9,8 ° of inclinations of internal thread, the wide 4mm of thread.
Sealing up screw through walls of the present utility model has following technical advantage:
1, easy to operate;
2, can significantly improve stagnant water effect;
3, can increase the pulling force of fixed form, ability to bear is strengthened greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model sealing up screw through walls.
Fig. 2 is the lateral view at the utility model sealing up screw depression through walls position.
Number in the figure: 1 sleeve pipe; 2 sealing pieces with holes; 3 is pullover; 4 screw threads; 5 depression positions.
The specific embodiment
Referring to Fig. 1 and Fig. 2, sealing up screw through walls comprises a centre with the sleeve pipe 1 of depressed part position 5, and sleeve pipe 1 two ends are provided with 4, one 2, two of sealing pieces with holes of internal thread and are positioned at the pullover 3 of sleeve pipe 1 two ends, and sealing piece 2 is located on the sleeve pipe 1 near depression position 5.
Described internal thread quantity is more than 9 or 9,8 ° of inclinations of internal thread, the wide 4mm of thread.
Embodiment recited above is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
