This structure has following problem, and the stagnant water screw rod both ends after the saw falls are directly scrapped, can not used repeatedly, and extravagant material is more, and economic benefits is not good enough, and the stagnant water screw rod that secondly has now is not good enough to the fixed effect of template, and when pouring, the template takes place vibrations or displacement easily.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a subway construction is with stagnant water pull rod structure, used repeatedly can be taken off to this structure outside screw rod, has better fixed effect to the template moreover, can guarantee the quality that the subway side wall was pour.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
a water stop pull rod structure for subway construction comprises a wall-in section and a detachable section, wherein the wall-in section comprises a wall-in pull rod and connecting nuts at two ends of the wall-in pull rod, the inner side of each connecting nut is fixedly welded with two ends of the wall-in pull rod, an inner threaded hole is processed at the central position of the outer side of each connecting nut, a circular groove is processed at the periphery of the inner threaded hole, a buffer ring and a waterproof rubber ring are sequentially filled in the circular groove, the detachable section comprises a template inner clamping plate, a template outer clamping plate and a detachable pull rod, a circular bulge is arranged at the central position of the inner side of the template inner clamping plate and embedded in the circular groove, a construction template is clamped between the template inner clamping plate and the template outer clamping plate, through holes are processed at the corresponding positions of the centers of the template inner clamping plate and the template outer clamping plate, external threads are arranged at two ends of the detachable pull rod, one end of the detachable pull, the other end is screwed in the locking nut to fix the template outer clamping plate.
Furthermore, a water stop sheet is welded and fixed at the middle position of the wall-entering pull rod.
Furthermore, a compression piece is welded on the detachable pull rod between the template inner clamping plate and the template outer clamping plate.
Furthermore, the contact area between the inner and outer formworks and the inner and outer sides of the construction formwork is two to three times of the area of the water stop sheet.
Furthermore, the depth of the circular groove is one half of the length of the connecting nut.
Compared with the prior art, the utility model has the advantages that:
the utility model fixes the construction template by matching the locking nut and the relevant parts through the template inner clamping plate and the template outer clamping plate with larger areas, has better stability and can ensure the pouring construction quality; can dismantle draw bar structure through the setting, after pouring, need not saw the outer two of stagnant water screw rod wall, can dismantle the recovery and recycle, economic benefits is better.
