Abstract
The invention provides a formwork bolting cushion block and a concrete formwork opposite-pull fastening device, and relates to a construction tool. The formwork bolt block comprises a conical cushion block which is provided with a central through hole, a small circular end of the conical cushion block is provided with a ring of circular stairs. The concrete formwork opposite-pull fastening device comprises formworks which are arranged in parallel, both ends of screws among the formworks are provided with formwork bolting cushion blocks in a penetrating mode, the screws are also provided with limiting parts which limit the axial displacement of formwork bolting cushion blocks on both sides. The formwork bolting cushion block can be produced by molds in a standardized way in factories, thus the trouble of fabrication and drilling on site is reduced. After the completion of concrete pouring, the formwork of the formwork opposite-pull fastening device is removed, the formwork bolting cushion block is taken off, and holes which are the same as the formwork bolting cushion blocks in size and shape are formed in the finished concrete wall. Consistent external dimensions and good quality of the concrete in the holes of the opposite-pull bolting protection layer cushion blocks are guaranteed.
Description
Technical field
The present invention relates to a kind of construction apparatus, specially a kind of template bolt cushion block and concrete blinding are to drawing fastener.
Background technology
, it is necessary to by fastening the template of casting concrete to drawing water-proof bolt in existing waterproof wall construction.At present, to drawing water stop wall-through bolt to be made up of the fixing bolt at screw rod and two ends, screw rod is made up of the screw portion through walls at middle part and the standing screw part at two ends, and sealing piece and banking stop are welded with screw portion through walls.
In concrete construction; being divided into has antiseepage requirement and without antiseepage requirement; there is the screw rod that exposed portion in cutting protective layer is needed after form removal of antiseepage requirement; hand-held corning machine is used during excision, the eyelet of diameter 35cm, depth 20cm is taken out at screw rod position, cut off the screw rod of exposed portion; it is bothersome laborious; and the repairing quality of eyelet is low, protective layer eyelet closure durability is not good enough, and influences overall perception effect.
And in the concrete construction without antiseepage requirement, typically split bolt is placed in PVC sleeve pipes, extract split bolt during form removal out, it is easy to that split bolt is secondary to be used, but in casting process, concrete grout can be flowed into PVC sleeve pipes, split bolt is caused to extract out difficult.
The content of the invention
It is easy to use it is an object of the invention to provide one kind, and efficiency of construction can be improved, simplify the template bolt cushion block and concrete blinding of concreting operation to drawing fastener.
Realizing the technical scheme of above-mentioned purpose is：Template bolt cushion block, including taper cushion block, the taper cushion block are provided with central through hole, and the small nose circle of taper cushion block is provided with a circle and the concentric ring-shaped step of taper cushion block, and the internal diameter of ring-shaped step is identical with the internal diameter of taper cushion block.
Second object of the present invention is to provide a kind of concrete blinding of application template bolt cushion block to drawing fastener.
Concrete blinding of the invention has antiseep requirement and without two kinds of antiseep requirement to drawing fastener to be divided into.
The template that the concrete blinding for having antiseep requirement be arranged in parallel to drawing fastener to include, many split bolts are provided with two side templates, split bolt includes screw rod, distinguish the template of protruding respective side in the two ends of screw rod, and fastened by nut, anchoring wooden unit is respectively arranged with screw rod between nut and the template of respective side, it is characterised in that：Screw rod two ends between template place the template bolt cushion block having the right described in requirement 1 respectively, the large round end surface of template bolt cushion block is fitted on the inwall of correspondence side template respectively, and the locating part for limiting two side template bolting pad block axial displacements is additionally provided with the screw rod.
The locating part includes being separately positioned on the banking stop at template bolt cushion block roundlet end, and banking stop is connected on screw rod.
To drawing fastener and the concrete blinding for having antiseep requirement essentially identical to the structure for drawing fastener, difference is concrete blinding without antiseep requirement：The locating part of the concrete blinding without antiseep requirement is to be placed on the PVC sleeve pipes between two side template bolting pad blocks on screw rod, and the two ends of the PVC sleeve pipes are placed on the ring-shaped step of correspondence Side Template bolting pad block respectively.
To drawing fastener after the completion of concreting, form removal removes template bolt cushion block to concrete blinding of the invention, and, hole that shape consistent equal with template bolting pad block size is formed in the concrete wall for pouring completion.
Beneficial effects of the present invention：
1st, template bolt cushion block can be standardized production in factory by mould, reduce field fabrication and drilling eye trouble.
2nd, it is easy to operate using template bolt cushion block, efficiency high.
3rd, template bolt cushion block can reuse at least 3 ∽ more than 4 times, reduce construction cost.
4th, there is the concrete blinding of antiseepage requirement to drawing fastener; after concrete construction; take out template bolt cushion block; the protective layer cushion block barrel hole size and depth that are formed on concrete wall can be made to meet current specifications requirement; favourable concrete durability, it is ensured that concrete appearance size one makes peace superior in quality at split bolt protective layer cushion block eyelet.
5th, the concrete blinding without antiseep requirement is to drawing fastener, in concreting process, PVC sleeve pipes coordinate with the template bolt cushion block sealing at two ends, concrete is avoided to flow into PVC sleeve pipes, after the completion of pouring, template bolt cushion block is taken out, extract split bolt out, template bolt cushion block and split bolt are reusable, have saved cost.
