Method and apparatus for constructing inner wall moulding board

Abstract

The present invention is the formwork construction method and apparatus for inner wall. The construction method includes demolding of formwork, lifting, supporting and expanding formwork, the lifting of formwork is completed with lifting machine; the demolding and expanding of formwork are completed by means of the transverse shift mechanism with rotating driving part pushing against the inner wall and linearly moving driven part connected to formwork; and the support of formwork in the clamping position in the inner wall is completed by means of the support part hinged to the lower part of the formwork. The formwork demolding and expanding screw transmission mechanism with boosting and back locking effect makes the operation easy and safe. The present invention can speed the construction and avoid heavy hoisting.

Description

1. Technical field: [0001] The invention relates to an interior wall formwork construction method and its device, and belongs to the innovative technology of the interior wall formwork construction method and its device. 2. Background technology: [0002] During building construction, the inner and outer formworks are often installed to maintain a certain distance for the grouting construction of the wall. When the grouting construction is completed, demoulding is required after the concrete is solidified, because the outer formwork is not affected by the space. Restricted, it can be easily disassembled. Due to the limitation of space, the inner formwork often needs to be pried or knocked on the formwork to remove the formwork, so it is easy to generate side pressure on the incompletely solidified concrete, causing it to collapse, so it cannot be self-supporting when the concrete is solidified. Early demoulding is carried out when the strength is high. Generally, it takes 24...

[0002] During building construction, the inner and outer formworks are often installed to maintain a certain distance for the grouting construction of the wall. When the grouting construction is completed, demoulding is required after the concrete is solidified, because the outer formwork is not affected by the space. Restricted, it can be easily disassembled. Due to the limitation of space, the inner formwork often needs to be pried or knocked on the formwork to remove the formwork, so it is easy to generate side pressure on the incompletely solidified concrete, causing it to collapse, so it cannot be self-supporting when the concrete is solidified. Early demoulding is carried out when the strength is high. Generally, it takes 24 hours or even more time to wait for the concrete to solidify, which is time-consuming and the construction speed is limited. No. 95101674.1 (Notice No. CN1127830A) discloses a building formwork demoulding method and device, which has the disadvantages of complex structure and inconvenient operation

In addition, Chinese Patent Application No. 98223894.0 (Notice No. CN2359390Y) discloses a climbing device for interior wall formwork. This device can avoid the friction between the formwork and the wall and reduce the occupied space. After the interior wall formwork is climbed, the construction of the lower floor needs to be carried out immediately, and the interior wall formwork cannot be supported until the floor is solidified. The construction speed is slow and the construction period is long. In addition, when the lower floor is constructed, the interior wall The template needs to be hung all the time, or it needs to be lifted from other places. The lifting task is heavy and the operation is inconvenient
