Description

[Detailed description of the invention] [Field of industrial application] The invention relates to a structure that supports the wall formwork when constructing a wall with a floor height different from the standard floor height. A fixed-sized panel consisting of a weir board and reinforcing thick timber fixed to its outer surface, spaced apart from each other by an interval corresponding to the thickness of the wall to be installed, and a panel with a vertical dimension shorter than that of the fixed-sized panel. The present invention relates to an improvement in a support structure for a wall formwork in which a shear plate and an auxiliary panel consisting of a reinforcing end material having the same thickness as the end material fixed to the outer surface of the shearing board are vertically arranged.

[Conventional technology]

Conventionally, as shown in the figure, a standard panel a having a vertical dimension corresponding to the standard floor height and an auxiliary panel b having a vertical dimension corresponding to the difference in floor height from the standard floor height are arranged side by side in the vertical direction. When forming a wall formwork, the outer surface of the auxiliary panel b is supported at multiple positions in the vertical direction by end pieces c made of steel pipes, etc., and these end members c, the outer surface, and the outer surface of the regular-sized panel a are supported. A steel pipe e with a length of about 1.5 m was placed across the thick end material d, and the steel pipes e located on both sides of the wall formwork were connected to each other via a separator f and a form tie g. h is a weir board (plywood) of the regular-sized panel a, and i is a reinforcing end piece (square lumber) fixed to the outer surface of the weir board h. j

[Problem that the invention attempts to solve]

In the above-mentioned conventional example, since a plurality of tiers of end pieces c are arranged on the outside of the auxiliary panel b, there is a drawback that a large amount of temporary material for support is used.

Furthermore, so-called two-hole form ties l having the minimum necessary length are used to connect the thick pieces c and the pieces d.
To connect the steel pipes e, a form tie that is longer than the form tie l by the thickness of the steel pipe e is required, and a so-called three-hole form tie g is used. As described above, since two types of form ties 1 and g are used for wall forms having different floor heights, it is troublesome to manage them.

The purpose of the present invention is to solve the problems of the above-mentioned conventional example.

[Means for solving problems]

The technical measures taken by the present invention to achieve the above objectives are as follows. That is, the feature of the present invention is that, in the support structure for wall formwork described at the beginning, a first holding rod has a thickness equal to that of the thick end material, and a second holding rod is in pressure contact with the outer surface of the thick end material of the auxiliary panel. and an auxiliary holding member integrally connected to the outer surface of the wall formwork, the first holding rod supporting the outer surface of the weir plate of the regular-sized panel, and the second holding rod supporting the edge of the auxiliary panel. The first presser rod is held between a horizontal thick piece of wood arranged so as to support the outer surface of the thick piece of wood, and spread over the thick pieces of each adjacent regular size panel, and a weir plate of the fixed size panel. However, the end pieces located on both sides of the wall formwork and the second presser rods are connected to each other via separators and form ties, respectively.

[Effect]

According to the above configuration, the outer surface of the thick material of the auxiliary panel is supported by the second holding rod of the auxiliary holding material, and the first holding rod of the auxiliary holding material is arranged across the thick material of the regular-sized panel. It will be supported by horizontal end pieces. The distance between the end pieces located on both sides of the wall formwork and the distance between the second presser rods located on both sides of the wall formwork are equal, and form ties of the same size can be used.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of a main part of a support structure for a wall formwork according to the present invention, FIG. 2 is a sectional view of a main part, and FIG. 3 is a plan view of a main part.

In the figure, reference numeral 1 denotes a fixed-length panel used as a wall formwork for a standard floor height, and is composed of a plywood sheath board 1a and reinforcing thick timbers (square timbers) 1b fixed to its outer surface with nails or the like. ing. Reference numeral 2 denotes an auxiliary panel, which is fixed to a plywood sheath board 2a having a vertical dimension shorter than the weir board 1a (a vertical dimension corresponding to the floor height difference from the standard floor height) and its outer surface with nails or the like. It is made up of a reinforcing round piece (square piece) 2b having the same thickness as the round piece 1a. These regular size panels 1 and auxiliary panels 2 are arranged side by side in the vertical direction, and adjacent thick pieces 1b and 2b are connected to each other with nails 3 to form a wall formwork. In the drawing, the auxiliary panel 2 is connected below the fixed-length panel 1, but it goes without saying that the vertical relationship may be reversed.

Reference numeral 4 denotes an auxiliary holding member made of a square steel pipe, in which a first holding rod 4a and a second holding rod 4b having the same thickness (thickness) as the thick end pieces 1b and 2b are connected with one side of one end side to each other. They are constructed by welding them together so that they are in contact with each other. Second presser rod 4
The length of the portion b that is not welded to the first presser rod 4a is set to be slightly longer than the vertical dimension of the auxiliary panel 2.

The auxiliary presser 4 supports the outer surface of the wall formwork, the first presser rod 4a supports the outer surface of the weir plate 1a of the regular-sized panel 1, and the second presser rod 4b supports the end thick material 2b of the auxiliary panel 2. is arranged to support the outer surface of the Reference numeral 5 denotes fixed-length panels 1 adjacent to each other on both sides of the wall formwork...each end piece 1b...
It is a horizontal steel pipe end material arranged across the end material 5 and the weir plate 1a of the regular size panel 1.
The first presser rod 4a is held between the two. The end pieces 5 located on both sides of the wall formwork and the second presser rods 4b are connected via separators 6 and form ties 7, respectively. 8... Wedge, 9... is a roughly L-shaped washer, 10...

In the above embodiment, the form tie 7 is inserted through the substantially L-shaped washer 9, but a through hole for inserting the form tie 7 may be formed in the second presser rod 4b of the auxiliary presser 4. Also, set the auxiliary presser 4 to 2.
Arrange the books adjacent to each other, apply a substantially U-shaped washer to the second presser rods 4b, 4b, and insert the form tie 7 placed between the second presser rods 4b, 4b into the washer. You can do it like this.

[Effect of idea]

The present invention has the above-mentioned configuration, in which the outer surface of the end piece of the auxiliary panel is supported by the second holding rod of the auxiliary holding member, and the first holding rod of the auxiliary holding rod extends over the end piece of the regular-sized panel. Since it will be supported by the horizontal end pieces placed in the horizontal direction, there is no need for the end pieces to support the end pieces of the auxiliary panel, and the amount of temporary construction materials used can be reduced. In addition, the form ties used to connect the end pieces (thick members that support the end pieces of the regular-sized panel) located on both sides of the wall formwork, and the second holding rods located on both sides of the wall formwork, Form ties used for connection need only have the same dimensions, and there is only one type of form tie, making it easy to manage the form ties.
