DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a window frame on a building to which a thermal insulation method is applied and an outer frame used for the method.

[0002]

2. Description of the Related Art Insulation methods for buildings, especially wooden houses, include (a) a filling insulation method in which a heat insulating material is filled between pillars in a large wall and (b) a heat insulating material outside a pillar. There is an external insulation method to attach. Hereinafter, the filling insulation method and the outer insulation method will be described. 6 to 9 are cross-sectional views showing an example of the filling and heat insulation method, FIG. 6 is a vertical cross-sectional view of the upper frame of the window frame and its periphery, and FIG. 8 is a cross-sectional view of the left vertical frame and its surroundings,
FIG. 9 is a cross-sectional view of the right vertical frame and its periphery.
10 to 13 are cross-sectional views showing an example of the external heat insulation method, FIG. 10 is a vertical cross-sectional view of the upper frame of the window frame and its surroundings, FIG. FIG. 12 is a cross-sectional view of the left vertical frame and its periphery, and FIG. 13 is a cross-sectional view of the right vertical frame and its periphery.

In the filling heat insulation method, the heat insulating material HIM is filled between the columns between the outer wall material 9 and the inner wall material 10 of the outer wall W, so that the window frame WF is mounted by a conventional method. Can be. That is, the outer peripheral surface of the window frame WF, in other words, the upper frame 1, the lower frame 2 and the left and right vertical frames 3
The mounting edges 1a, 2a, 3a, 4a protruding outward along a vertical plane common to the outer peripheral surface of the outer peripheral surface of the window 4 constitute the window frame 5, lintel 6, and left and right pillars 7, 8 It is fixed with a wood screw s1 in a state in which it is in contact with the outdoor side surface, and mounting edges 1b, 2b, 3b, 4b formed on the indoor side ends of the upper frame 1, the lower frame 2, and the left and right vertical frames 3, 4 are fixed. The windowsill 5, the lintel 6, and the inner peripheral surfaces of the left and right pillars 7, 8 are respectively fixed by wood screws s2. Reference numeral 11 denotes an inner picture frame which is attached to improve the inner appearance by hiding the space between the indoor side end of the window frame and the parting of the inner wall material 10 after the window frame WF is attached. However, since the heat insulating material HI is divided by columns other than the columns 7 and 8 and those columns having low thermal conductivity are in direct or indirect contact with the outer wall member 9 and the inner wall member 10, the outer wall has If the improvement of the heat insulating property is restricted, and if the dew forms on the front surface or the back surface of the pillar or the heat insulating material HIM, the condensed water is held by the skeleton, and there is a problem that the skeleton deteriorates early.

On the other hand, in the external heat insulation method, the heat insulating material HIM is stuck to the outside of the pillar, so that the heat insulating material can be continued without being divided into the pillar, and therefore, dew condensation on the pillar is prevented. However, even if dew forms on the front or back surface of the heat insulating material, the dew does not penetrate to the skeleton, so that there is no problem of dew formation. However, since the heat insulating material HIM is stuck to the outside of the pillar, the thickness of the outer wall, that is, the distance from the outdoor side surface of the outer wall material 9 to the indoor side surface of the inner wall material 10 becomes larger than that in the case of the filled heat insulating method. First, a peripheral edge 12 having a required cross-sectional dimension is added to a window opening frame, that is, a window sill 5, a lintel 6, and left and right pillars 7 and 8 so as to be continuous in a rectangular shape. After that, the window frame WF is attached in a conventional manner, that is
a, 2a, 3a, and 4a, the indoor side portion is fitted into the peripheral edge 12, and the mounting edges 1b, 2b, 3b, and 4 of the window frame are fitted.
b is screwed to the inner peripheral surface of the peripheral edge 12, and each mounting edge 1 a, 2 a, 3 a, 4 a is screwed to the outdoor side surface of the peripheral edge 12 and attached. Then, the end surface of the heat insulating material HIM is brought into contact with the outer peripheral surface of the peripheral edge 12 and the heat insulating material is attached thereto. Subsequently, the outer wall material 9 is separated from the peripheral edge 12 and the heat insulating material HIM in the outdoor direction by the body edge 13 or the like. The outer wall material 9 is fixed in a state where one edge of 9 is received on the outer peripheral surface of the window frame.

[0005]

However, in the conventional external heat insulation method, first, it is necessary to attach the peripheral edge 12 to the outdoor side surface of the window opening frame as described above. Second, the thickness of the insulation HIM is 40 m by the building contractor.
Since there are various types in the range of m to 80 mm, the peripheral edge must be procured according to the thickness of the heat insulating material.
Third, an inner frame 11E that covers a space between the indoor end of the window frame and the parting of the inner wall material 10 is attached around the indoor side of the window opening. , It is necessary to use an inner frame 11E having an expected width larger than the inner frame used in the case of the filling and heat insulating method. As described above, the window frame mounting method in the conventional outer insulation method is based on the heat insulating material H used.
Various peripheral edges 12 and inner frames 11E depending on the thickness of the IM
Had to be prepared.

[0006] The present invention has been made in view of the above points, and its object is to attach a window frame by a normal mounting method, regardless of the thickness of a heat insulating material used in the external heat insulating method. Provided is a method for mounting a window frame that can be mounted on a window opening frame in the same manner as in the case of the filled insulation method and that can use an inner frame having a normal expected width similar to the case of the filled insulation method. Is to do. It is another object of the present invention to provide an outer frame in which the mounting efficiency and the watertightness are improved when the above-described window frame mounting method is performed.

[0007]

In order to solve the above-mentioned problems, a method for mounting a window frame according to the present invention comprises the following steps. (1) A window frame is attached to a window sill, a lintel, and left and right pillars forming a window opening by an ordinary method. (2) At the same time as or after the mounting of the window frame, on the outdoor side surfaces of the window sill, lintel, and right and left pillars, project from each surface to the outdoor side, and form an outer frame continuous in a rectangular shape along the window frame. The window frame is fixed in close contact with the outer peripheral portion. (3) Then, the heat insulating material is attached to the outdoor side of the pillar with one end of the heat insulating material in contact with the outer peripheral surface of the outer frame. (4) One end edge of the outer wall material is received by the outer peripheral surface of the outer frame on the outdoor side of the heat insulating material.

[0008] The outer frame is formed by connecting, in a rectangular shape, outer frame members formed of hollow windows corresponding to a window sill, a lintel, and right and left pillars forming a window opening. The indoor side end surface has an attachment edge that extends to the outer periphery and is fixed to the window lintel, lintel and left and right pillars, and the indoor side end is the window sill of the window frame, lintel and left and right. It is characterized by being connected to a mounting edge fixed to the column. With the above configuration, the outer frame is connected to the mounting edge of the window frame before or after being mounted on the window opening frame. Further, the outer frame has its mounting edge fixed to the outdoor side surface of the window opening frame.

Each of the outer frame materials corresponding to the lintel and the left and right pillars has an inner peripheral surface of the outer frame projecting inward at an intermediate position between the inside and the outside of the inner frame to connect the outer frame to the window frame. It is desirable to provide an airtight edge which is in close contact with the outdoor side end of the upper frame and the left and right vertical frames. By the airtight edge, the space between the outer frame and the outdoor side end of the window frame is sealed, and intrusion of rainwater and dust from between the window frame and the outer frame is prevented, and
The appearance of the window frame is improved.
