Novel environment-friendly noise-free quick surrounding and pulling device for water conservancy building construction

Abstract

The invention discloses a new device for water conservancy construction, which is environmentally friendly and noiseless, and quickly surrounds and pulls a new device. Because an internal force gear is arranged in a tensioning tube, one side of the internal force gear is provided with a positive full-wire shaft, and the positive full-wire shaft is outside the shaft. Set the positive inner full wire tensioning sleeve, and the other side is equipped with a reverse full wire through shaft, and the reverse full wire through shaft is equipped with a reverse inner full wire tensioning sleeve, which is characterized in that: when the special fastening After the external force gear of the gear box meshes with the internal force gear in the tension tube, the internal force gear can realize the forward full wire through shaft and the reverse full wire through shaft on both sides of itself, and then the forward full wire through shaft can be turned inward. The whole wire tensioning sleeve, the reverse inner full wire tensioning sleeve is quickly tightened inward.

Description

technical field [0001] The invention relates to a building formwork tool, and directly relates to an environment-friendly, noiseless and fast enclosure device for water conservancy construction, and is especially suitable for use in the occasion of building formwork support. Background technique [0002] In the formwork construction of modern buildings, the formwork method 1. In order to completely prevent the deformation, cracking and convex belly of the column and beam during pouring, it is necessary to use a drilling tool to drill a hole in the middle of the formwork and insert a long bolt into the hole. Then pass through the preset plastic tube and then penetrate into the corresponding hole of the other template, then place the two steel tubes on both sides of the long bolt, and then use the long ear pads to buckle on the two steel tubes and then insert them The nuts are tightened. Formwork support method 2. Several steel pipes are used to tighten around the mold body a...

Problems solved by technology

Formwork support method 2. Several steel pipes are used to tighten around the mold body after forcibly enclosing and pulling through positive and negative tensioners. The common disadvantages of forcibly enclosing and pulling through positive and negative tensioners are: It is necessary to use the hammer head to hit the mold body and the positive and negative tensioner heavily. When the hammer head is used to hit the mold body and the positive and negative tensioner heavily, a strong resonance source will easily appear

3. The formwork construction is uncivilized, inconvenient, not fast, the labor intensity of the operators is high, and the work efficiency is low
