Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a mounting structure for a corner face tree around an opening or the like when a wall surface is exposed.

(Prior Art) FIG. 3 shows a conventional structure of this type, in which a corner siding (a) is provided at the corner between the opening molding dam (b) and the outer mold (c). It is inserted and nailed to the weir plate (b).

In the figure, (d) is a tree, (e) is an inner formwork, (f) is cast concrete, (g) is an opening steal plate, and (h) is an opening frame anchor.

(Problems to be Solved by the Invention) In the above-mentioned conventional structure, since the face plate is attached to the weir plate, it is easily damaged when the formwork is assembled, concrete is poured, or the like. You have to use a new face plate each time,
Mounting accuracy is poor. Furthermore, there is a problem in that it may be contained during the assembling of the formwork and during the placing of concrete, and the concrete may flow into between the weir plate and repair after dismantling the formwork.

The present invention has been proposed in view of the problems of the above-mentioned prior art, and the object of the present invention is to divert the face wood,
The point is to provide a facet mount structure with good mounting accuracy and good workability.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a skirting board mounting structure for a projected corner according to the present invention has a chamfered upper end surface and a horizontal lower end surface, and an outer side of both upper and lower end surfaces thereof. It consists of an outer vertical surface and an inner vertical surface that are connected to each other between the inner edge and the inner edge, and the inner vertical surface has a trapezoidal cross section formed in the same size as the sum of the opening molding dam plate and the Satsuki thickness. Fixing the corner siding to the outer wall formwork arranged around the opening, the inner vertical surface of the siding is on the weir board and the tree, the lower bottom surface of the tree and the horizontal lower end surface. It is configured to be fixed so as to be located on the same plane.

(Operation) According to the present invention, the trapezoidal cross-section corner siding is fixed to the outer wall mold and the outer stencil is assembled at a predetermined position, and the inner vertical surface of the stencil is the weir plate thickness for forming the opening. Also, by utilizing the fact that it is formed to have a size equal to the sum of the thickness of the tree, the same tree is used as a ruler for the opening form, and the lower end horizontal plane and the lower bottom of the tree are located on the same plane. After fixing the face plate to the weir plate and the tree, after accurately positioning the chamfered upper end face of the same tree at the corner between the outer wall formwork and the opening forming weir plate,
The inner formwork is assembled and concrete is poured.

Thus, after the cast concrete is hardened, the face tree is removed from the mold together with the outer formwork, the corner portions of the opening are molded by the same facework, and the outer formwork is also used for other purposes.

(Embodiment) An embodiment shown in the drawings, in which the present invention is applied to a work around a window stand, will be described below.

(1) is a chamfer for corners, and the chamfered top surface (1a),
Horizontal bottom surface (1b), outer vertical surface (1c), inner vertical surface (1d)
Is formed in a trapezoidal cross section, and the inner vertical surface (1d) has a dimension l (= the sum of the opening forming dam plate thickness t ₁ and the Satsuki thickness t ₂
t ₁ + t ₂ ).

Then, the face plate (1) is fixed to the outer wall form (2) with nails (3), the outer wall form (2) is assembled at a predetermined position, and then the face plate (1) is used for forming an opening. The weir plate (4) and the wood (5), the nail (6) so that the lower bottom surface of the wood (5) and the horizontal lower end surface (1b) of the wood (1) are located on the same plane. Stick with.

At this time, as described above, the dam plate (4) of the face plate (1) and the tree
Since the dimension l of the inner vertical surface (1d) facing the (5) side is equal to the sum (t ₁ + t ₂ ) of the dam plate thickness t ₁ and the saw tree thickness t ₂ , the chamfered top surface of the chamfer (1) (1a) is accurately located at the corner between the outer wall formwork (1) and the dam plate (4).

After that, the inner formwork (7) is assembled, the concrete (8) is cast, and the casting concrete (8) is cured and then demolded, and the corner portion is molded by the face board (1). The face plate (1) is used together with the outer wall formwork (2).

(10) in the figure is an anchor for the opening frame.

(Effects of the Invention) As described above, the present invention uses a chamfer having a trapezoidal cross section including a chamfered upper end surface, a horizontal lower end surface, and an inner and outer vertical surface, and the same chamfer is used as an outer wall form The inner vertical surface of the same tree has a dimension equal to the sum of the opening forming dam plate and the thickness of the tree. It is possible to fix the face plate to the dam plate and the base tree so that and are located on the same plane, and to accurately dispose the face frame at a predetermined position by using the face plate as a ruler for the opening form frame.

Further, according to the present invention, since the face plate is fixed to the outer wall formwork and is integrated with the outer wall formwork, the face plate is less likely to be damaged when the formwork is assembled or concrete is cast, and can be diverted.
Further, since the face plate is fixed to the outer wall formwork in this way, the mounting accuracy is good and the workability is good. In the case of the outer wall large panel construction method or the same window position on each floor, the mounting can be done only once.
