Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer peripheral curing panel for curing an outer peripheral surface of a floor before installation of an outer wall member during the construction of a high-rise building or the like constructed using building technology. The present invention relates to a completely new type of outer peripheral curing panel having not only a function as outer peripheral curing means but also a function as a hanging jig for lifting an outer wall member by a tower crane.

[0002]

2. Description of the Related Art Conventionally, in a high-rise building under construction, means for curing an outer peripheral surface of a floor where a steel frame is exposed and an outer wall member is not attached is provided as follows.
Hanging the curing net from the upper floor of the constructed steel frame and fixing it to the lower floor using a rope, etc., or a temporary bracket where the outer peripheral curing frame with the curing net stretched on the frame is attached to a pillar or beam And a bolt and a nut are used for fixing.

According to the means for curing these outer peripheral surfaces,
It is possible to prevent materials, tools and the like from falling from inside the building during construction, and at the same time, to blindfold the inside of the building from a third party outside the building.

However, when these means for curing the outer peripheral surface are used, as the construction progresses and the outer wall member is attached, the curing net and the outer peripheral curing frame are sequentially attached or rearranged. Therefore, the following inconveniences existed.

[0005] That is, when using a curing net, an operator must go up to the top floor of the building and bind a rope related to the curing net when attaching or changing the curling net. Working at high altitudes under extreme conditions is extremely dangerous and is not preferred in terms of safety.

[0006] Further, in the case of using the outer peripheral curing frame, it is necessary to use a tower crane to perform a refilling operation. Each time, the tower crane must be restrained for the operation. However, the work time for mounting the outer wall member and assembling the steel frame, which are the essential work of the tower crane, is hindered by the work, resulting in a longer construction period and a higher cost.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention can improve safety by avoiding work at a high place in a state where the scaffold is unstable, and can reduce the inherent working time of the tower crane. An object of the present invention is to provide an outer peripheral curing panel capable of shortening a construction period without obstructing.

[0008]

That is, an outer peripheral curing panel according to the present invention is erected on an outer edge of a beam member on a reference floor, and cures an outer peripheral surface on a reference floor and an upper floor than the reference floor. It is characterized by integrally comprising a panel-shaped curing frame and a suspending jig for suspending an outer wall member related to a lower floor than the reference floor.

In such a technical means, the curing frame can be erected on an outer edge portion (for example, a primary fastener processed into a steel frame) of a beam member on a reference floor,
And if it is a panel-like thing that can cure the outer peripheral surface of the reference floor and the upper floor than the reference floor, its configuration may be selected as appropriate, for example, a net member inside the frame member. A stretched one, a plate-like panel itself, or the like can be used.

When the curing frame is of a type having a net member, from the viewpoint of flexibly responding to the strength of the wind pressure received by the curing frame, a storage device for storing the net member of the curing frame is provided. It is preferable that the setting of the opening area corresponding to the area of the accommodated net member is free.

Further, even in the case where an unexpected situation such as a case where the curing frame is blown by a strong wind or the like occurs, from the viewpoint of preventing the curing frame from falling over and ensuring safety, the curing frame is not required. It is preferable that a stay member connecting the pillar member and the pillar member on the reference floor is provided to prevent the curing frame from falling over.

[0012] Further, as the hanging jig, if a hanging wire from a tower crane can be connected to an outer wall member which is a suspended load, and if it can sufficiently withstand the weight of the outer wall member, the hanging jig can be used. The configuration may be appropriately selected according to the shape of the outer wall member and the like. For example, a part of the curing frame may be used.

Further, from the viewpoint of mounting the outer wall member more quickly and easily after the curing frame is erected, it is preferable to include up-and-down elevating means for raising and lowering the suspended outer wall member.
