The steel strand counter-pulling reinforced template construction process has high tensile strength, and the lateral pressure and the construction load of newly poured concrete can be counteracted through the pre-tensioning force of the steel strands, so that the template is ensured not to deform in the pouring process; the flexibility of the steel strand makes the repeated utilization rate of the steel strand very high, the steel strand is rarely pulled out after being demoulded, and the problem that the conventional tie rod is often left in a concrete structure is solved.
Disclosure of Invention
The utility model aims to provide a reinforcing anchorage device of a steel strand counter-pulling reinforcing template, which has high tensile strength by adopting the steel strand counter-pulling reinforcing construction, can offset the lateral pressure and the construction load of newly poured concrete by the pre-tensioning force of the steel strand, and ensures that the template is not deformed in the pouring process; the flexibility of the steel strand makes the repeated utilization rate of the steel strand very high, the steel strand is rarely pulled out after being demoulded, and the problem that the conventional tie rod is often left in a concrete structure is solved.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
a reinforcing anchorage device of a steel strand counter-pulling reinforcing template comprises an anchorage device main body and a length adjuster, wherein the anchorage device main body is cylindrical, and a conical through hole is formed in the middle of the anchorage device main body; the length adjuster comprises an adjusting nut, a nut and a through-core thread sleeve, the PVC sleeve is fixed in the template, the steel strand penetrates into the PVC sleeve, a back ridge is added on one side of the template, and a base plate, the through-core thread sleeve of the length adjuster, the nut, the adjusting nut, the anchor device main body and the tool clamping piece are sequentially installed on the outer side of the back ridge.
The length adjuster is formed by processing a high-strength bolt, a hole is drilled in the middle of the high-strength bolt, the hole diameter is 16mm, and the maximum length of the length adjuster is 4 cm.
When the anchor is used, the template is installed firstly, the back edge is added on one side of the template, the PVC sleeve is penetrated, then the steel strand is penetrated from the inside of the PVC sleeve, and the backing plate, the length regulator, the anchor main body and the tool clamping piece are sequentially installed on the outer side of the back edge. Firstly, the inner support steel pipe is reasonably positioned, and the stretching amount is adopted to control the tensile force which is not less than the concrete side stress and the construction stress to the steel strand (the sizes of the structures are different, the side stress and the construction stress are also different, and the template reinforcing effect can be judged through calculation or experience). Because the top of the screw is anchored by an anchor clamp, the length of the screw screwed into the through-center threaded sleeve is adjusted by a wrench or a pipe wrench to apply prestress to the steel strand, thereby achieving the purposes of tensioning the steel strand and reinforcing the template; and (4) screwing the screw into the through-core threaded sleeve by the same principle when the anchor is withdrawn, knocking the anchor withdrawing clamp, and withdrawing the anchor.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model adopts the steel strand as the pull rod, the method that the two ends adopt the tool anchor to anchor replaces the traditional round steel pull rod to reinforce the template, the steel strand has high tensile strength for the opposite pulling reinforcement construction, the lateral pressure and the construction load of the newly poured concrete can be offset by the pretension force of the steel strand, and the template is ensured not to deform in the pouring process; the flexibility of the steel strand makes the repeated utilization rate of the steel strand very high, the steel strand is rarely pulled out after being demoulded, and the problem that the conventional tie rod is often left in a concrete structure is solved.
