Abstract

PROBLEM TO BE SOLVED: To facilitate mounting and reduce cost by forming the mounting part to be mounted on a window frame integrally with the right and left vertical frames of a coped joint, and fixing together the decorative material of the window frame with rivets when the coped joint is installed on the window frame. SOLUTION: A platy mounting part 11a is formed integrally on the end surface 11b of right and left vertical frames 11 which constitute a coped joint 10, and the top end of the mounting part 11a is engaged with the top end of a window frame 20 and, at the same time, the decorative material 30 of the window frame is also installed and fixed with rivets 50. In this mounting, when a positioning projection 11c provided at the mounting part is brought in contact with the top end of the window frame 20, rivet holes provided into the mounting part 11a are matched with those provided in the window frame 29. By this, it can be mounted without requiring any extra mounting fitting. Thus the man- hour for installation can be reduced remarkably.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment structure for a surface lattice provided on a sash frame of a building.

[0002]

2. Description of the Related Art Conventionally, a surface lattice attached to a frame provided on an outer wall of a building is attached to the outside of an external sash window frame as described in, for example, Japanese Patent Publication No. 56-47353. In such a case, it is general that a mounting bracket manufactured separately from the surface lattice is attached to the surface lattice and integrated, and the mounting bracket is fixed to the frame. When a decorative material is attached to the sash window frame, it is attached separately from the surface lattice.

[0003]

However, in the above window frame, when both the surface lattice and the decorative material are attached, the surface lattice and the decorative material are separately attached to the window frame. However, the surface lattice has a problem that the cost for manufacturing the mounting bracket and the cost for processing the mounting are separately required, and the cost is increased due to the increase in man-hours.

The present invention has been made by paying attention to the above-mentioned problems, and an object of the present invention is to solve these problems and to attach a decorative material to the frame of the surface lattice. By using the mounting part of the same as the mounting part of the surface lattice, the mounting can be performed integrally at the same time, and the number of mounting members can be reduced.
It is intended to provide a surface lattice mounting structure capable of significantly reducing the number of mounting steps.

[0005]

In the mounting structure of the surface lattice of the present invention, the mounting portion projecting from the frame of the surface lattice, the decorative material of the window frame, and the window frame body are fixed at their three fixed positions. In the state of being overlapped with each other, a through hole penetrating the three is provided, and a fixing metal fitting is inserted into the through hole to fix the three.

[0006]

In the mounting structure of the surface lattice of the present invention, since the mounting portion of the surface lattice is integrally fixed to the sash frame main body together with the decorative material of the sash frame at the same time, no extra mounting member or the like is required, so that the cost is reduced. It is possible to reduce the number of installations, and the installation work can be done easily, and the number of installation steps can be greatly reduced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an example of an area lattice in the area lattice mounting structure of the present invention. In FIG. 1, the area lattice 10 is a frame structure in which a pair of vertical frames 11, 11 and an upper frame 12 and a lower frame 13 are bridged between the upper and lower ends of the vertical frames 11, 11 to form a frame. , 11, between the upper, middle and lower cross rails 14, 1 in a substantially horizontal direction.
Nos. 4 and 14 are provided so as to span each.
Further, in the vertical direction, vertical crosspieces 15, 15 having both appearance design and crime prevention are attached at a relatively small pitch to form the surface lattice 10.

As will be described in detail below, the vertical frame 11 constituting the above-mentioned surface lattice 10 is integrally formed with a mounting portion to a window frame.

Starting from the vertical frame 11 which constitutes the surface lattice 10,
As the upper and lower frames 12, 13, the horizontal rails 14, the vertical rails 15, and the like, those formed by extrusion of a light metal such as aluminum having excellent spreading characteristics at room temperature are preferably used. In addition, molding is possible even if the cross-sectional shape is quite complicated. Utilizing this characteristic effectively, the surface lattice 10 of the present invention is formed in the following structure.

FIG. 2 is a sectional view taken along the line AA of FIG. 1 and shows a main part thereof. In FIG. 2, the rectangular vertical frames 11 having the left and right hollow cross-sections of the surface lattice 10 are formed by extrusion molding extruding in the longitudinal direction, and from the edge on the building side, the window frame is formed. Attached to 11
The a and 11a are formed so as to extend substantially flush with the outer end surfaces 11b and 11b of the vertical frame 11.

Further, the outer end surface of the mounting portion 11a is brought into contact with a window frame at the time of mounting, and a projection 11c for positioning is provided.
11c is provided.

As shown in the side view of FIG. 3, the mounting portion 11a is formed in a flat plate shape between the lower end of the upper frame 12 and the upper end of the lower frame 13. Also, the mounting portions 11a on both sides of this

(Embodiment) An embodiment will be described below with reference to the drawings. FIG. 4 is a cross-sectional view of the surface lattice mounting structure of the present invention, and FIG. 5 is a cross-sectional view taken along the line BB of FIG. As shown in FIGS. 4 and 5, the area lattice 10 includes a window frame body 20 of a window.
In addition, the decorative material 30 of the window frame is integrally attached by rivet caulking.

Attachment pieces 21 for attaching the surface lattice 10 and the decorative material 30 are provided on the outside in a vertical direction on both sides of the window frame body 20 to which the surface lattice 10 is attached. This mounting piece 2
In the vertical direction of 1, a similar through hole (not shown) is provided at a position corresponding to the through hole 11d of the rivet provided on the surface lattice 10. A receiving piece 22 is provided at the lower end of the mounting piece 21 so as to project inward.

The window frame main body 20 is provided with a fixing portion 23 projecting outward, and the fixing portion 23 is provided with an outer wall material 40 at the opening end stretched via waterproof sealing materials 25 and 26. It is fixed to the material 41 with screws 24.

The decorative material 30 is attached so as to cover the outer circumference of the window frame body 20, has a cross section close to an L shape as shown in the drawing, and has an end portion with respect to the face material 40. The side piece 31 and the front piece 32 are in contact with each other substantially vertically, and a fixing piece 33 is provided to project inward from the inner end of the horizontal piece 32 toward the inside. Further, in the vertical direction of the fixing piece 33, similar through holes (not shown) are provided at positions corresponding to the through holes of the rivets of the window frame body 20.

The mounting of the area grating is performed as follows. That is, the fixed piece 33 of the decorative material 30 is brought into contact with the inside of the attachment piece 21 of the window frame body 20, and the tip of the attachment portion 11a of the surface lattice 10 is brought into contact with the inside of the fixed piece 33. The fixing piece 33 of the decorative material 30 is positioned so as to be sandwiched by the projection 11c of the mounting portion 11a and the receiving piece 22 of the window frame main body 20.
No. 0, the surface lattice 10 is fixed by being caulked by the caulking rivets 50 penetrating the three through holes of the surface lattice 10, and the surface lattice 10 is attached together with the decorative material 30 of the window frame 20 at the same time. .

Therefore, unlike the conventional method of mounting the surface lattice, the mounting portion 11a formed on the surface lattice 10 can be installed in advance as described above without using a separate mounting bracket or the like. Since it is attached to the window frame body 20 together with the decorative material 30 by rivet crimping, the cost of the surface lattice can be reduced, the installation work can be done easily, and the installation man-hours can be greatly reduced. Can also be robust.
