Abstract
The utility model discloses an external connection type waterproof and wall-traversing double end screw, comprising an outer screw, a nut, water stop strips and an inner screw. The outer and inner screws are both double-end external screw thread structures with equal weight and equal size. The water stop strips are mounted on the outer wall of the middle section of the inner screw in series and are fixedly connected to each other. The nut is a thickening member. The inner screw is coaxially connected to the outer screw through the nut. The linear distance between end faces of the nut connected to two ends of the inner screw is equal to the construction thickness of basement shear wall. The double end screw cooperates with a template, and concrete is poured. After the concrete is solidified, the template and the outer screw are removed in order. With the structure, no waterproof and wall-traversing double end screw exposes outside of two side faces of the shear wall. The function of water seepage resistance of the waterproof and wall-traversing double end screw is maintained, and subsequent construction will not be affected. More importantly, no mechanical cutting devices are required and safety is good without open fire work. In addition, the dismounted outer screw can be repetitively used, saving materials and reducing construction cost.
Description
Technical field
The utility model relates to a kind of building operations hardware, and specifically, the utility model relates to a kind of waterproof double threaded screw through walls that is used for the basement shear wall template.
Background technology
Basement shear wall is the supporting member of building, and is special because of its present position, except that having normal structural strength requirement, also adds the percolation-proof requirement.The basement shear wall construction at first will be preset template, and setting up two side templates must connect with waterproof double threaded screw through walls.The waterproof of prior art double threaded screw through walls is made of with the sealing sheet of fixedlying connected screw rod.The main part of waterproof double threaded screw through walls forever is retained in wherein after the concrete setting, and the two ends revealed section then slices off after the template dismounting.Simple, fixing reliable, the convenient disassembly of this syndeton, screw rod place do not have infiltration, satisfy the construction requirement of basement shear wall fully.But prior art waterproof double threaded screw through walls uses the outer termination that is exposed at the shear wall both sides, back to slice off, otherwise influences follow-up construction.Be not difficult although slice off waterproof double threaded screw through walls two ends technology, exist work with torches easily to form potential safety hazard, also exist the two ends of cutting off to become waste material, cause certain waste thus, increase the engineering construction cost.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of simple and reasonable for structurely, connects reliable, convenient disassembly, keeping both without work with torches, also can not producing the circumscribed waterproof double threaded screw through walls of waste on original waterproof construction basis of invariable.
The utility model is achieved through the following technical solutions technical goal.
Circumscribed waterproof double threaded screw through walls, it is made up of external screw rod, nut, sealing sheet and inner screw.Described external screw rod and inner screw are the double thread structure.Described sealing sheet string is on the outer wall of inner screw stage casing and the connection that fixes.Its improvements are: described nut is a thickening piece, and inner screw is connected by nut is coaxial with external screw rod.
In the said structure, air line distance equals basement shear wall construction thickness between the nut outer face that the inner screw two ends connect.Screw thread nominal size on external screw rod, inner screw and the nut is identical, is right-handed thread.
The utility model compared with prior art has following good effect:
1, divide section connection structure simple, fixing reliable, convenient disassembly;
After the concrete setting of 2, building, the external screw rod that unloads can use repeatedly, saves construction cost;
3, the external screw rod dismounting belongs to flames of anger operation, and safety is good.
Description of drawings
Fig. 1 is that the utility model is set in the horizontal section schematic diagram in the basement shear wall.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Circumscribed waterproof shown in Figure 1 is worn double threaded screw, and it is made up of external screw rod 1, nut 2, sealing sheet 3 and inner screw 4.Described external screw rod 1 and inner screw 4 are the double thread structure, and sealing sheet 3 is gone here and there on inner screw 4 stage casing outer walls and the connection that fixes.Described nut 2 is a thickening piece, and inner screw 4 and external screw rod 1 are by 2 coaxial connections of nut.The wide 500mm of basement shear wall in the present embodiment, inner screw 4 two ends attaching nuts 2 length overalls that preset equal 500mm, then at the identical external screw rod 1 of the nut 2 two ends external nominal size of difference, again from both sides difference mounting template, by external screw rod 1 locking template.After the concrete setting to be built, order is laid down template and external screw rod 1, this structure accomplishes that the shear wall two sides do not have waterproof double threaded screw through walls to expose, both kept outside the percolation-proof function of waterproof double threaded screw through walls, do not influence follow-up construction yet, importantly do not need to employ machine cuts equipment, do not have work with torches, guarantee safety of construction.The external screw rod 1 that unloads can use repeatedly, has saved material thus, reduces construction cost.
