JP3716390B2 - Assembling and dismantling method of wall with large plate formwork - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a large formwork erection / disassembly method implemented in assembly / disassembly work of a large formwork used in construction of a concrete building or the like.
[0002]
[Prior art]
Conventionally, in formwork such as construction of a concrete building, a method of separately mounting and dismantling walls and beams has been performed.
[0003]
[Problems to be solved by the invention]
The aging of the formwork in recent years, the shortage of manpower, and cost reduction are considered to be urgently needed, which is a safe and non-skilled construction method. Currently, the general construction method is a method in which concrete is placed only on the wall part and the beam slab is placed at the same time. Since it is difficult to measure, it is considered that the problem to be solved is that it can be safely advanced quickly in one operation.
[0004]
Accordingly, an object of the present invention is to provide a system formwork that can efficiently and safely disassemble the beam-attached portion of the large formwork in a consistent and reliable manner.
[0005]
[Means for Solving the Problems]
As means for solving the above-mentioned problems, the large-frame formwork erection / disassembly method according to the present invention includes a main body (A) and a beam bottom part (A) and a beam bottom part of a large-size beam-attached wall as shown in the drawings. B) is fixed with bolts, the concrete bolts are solidified and loosened, and the A part is peeled off by pulling the main body (A) at a slight angle with a crane. The B part is attached to the A part and can be disassembled, and can be moved to the next set part by retightening the bolt.
[0006]
[Action]
The main plate body (A) and beam bottom (B) of the large plate are fixed with bolts and upright with a support built by a crane, and the opposite large plate is built by a crane. Is fixed with bolts and nuts.
[0007]
【Example】
Embodiments of the present invention shown in the drawings will be described. Fix (B) to the main body (A) with bolts on the ground, and stand upright at the lifting set position with a crane. Maintain upright with the support, match the opposite panel and unify both with the separator tightening bolts and nuts. After pouring concrete, solidifying the concrete, removing the bolts and nuts for tightening the separator, releasing the integration of both panels, loosening the bolts fixing the main bodies (A) and (B), and pulling the main body A diagonally with a crane As a result, the member (B) is slightly delayed from the beam bottom and the dismantling is completed. Repeat the same process and proceed with the large formwork process.
[0008]
【The invention's effect】
The system method of the large formwork according to the present invention is a method that allows the large formwork of the beam-attached wall part to be built at the same time, can be safely disassembled at the same time, and a series of operations can be performed quickly without being a formwork carpenter. The crane operation becomes fully operational and the efficiency (productivity) can be greatly increased, which greatly contributes to the reduction of construction costs and the construction period.

Claims (2)

  A method of erection and dismantling of a wall mold with a beam mold for constructing a wall with a concrete beam, the wall mold with a beam mold comprising a beam bottom mold and a mold body, The beam bottom mold is formed by a bolt extending from the pin toward the stopper plate and a nut provided on the bolt via a pin provided on the beam bottom mold and a stopper plate provided on the mold body. Fixing, forming the above-mentioned formwork main body and the above-mentioned beam bottom formwork as a wall formwork with a beam form, placing it at a predetermined position, placing concrete, and at the time of dismantling the formwork after concrete hardening, Move the nut, loosen the bolt, then peel off the formwork body from the concrete, the beam bottom formwork is peeled off the concrete behind the formwork body, dismantle the beam form wall formwork, Wall formwork with beams Like an anchor and method of demolition.   A wall mold with a beam mold for constructing a wall with a concrete beam, the wall mold with a beam mold is composed of a beam bottom mold and a mold body, and the mold main body and the beam bottom mold are It is fixed by a bolt extending from the pin toward the stopper plate and a nut provided on the bolt via a pin provided on the beam bottom mold and a stopper plate provided on the mold body. The beam bottom mold is integrated into a wall mold with a beam mold, and when the mold is disassembled after the concrete is hardened, the nut is moved, the bolt is loosened, and then the mold body is peeled off from the concrete. The beam-bottom formwork is peeled off from the concrete with a delay from the above-mentioned main body, and the beam-type wall formwork is disassembled.
