DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure around a window of a building, particularly a building in which bricks (tiles) are stretched on an outer wall.

[0002]

2. Description of the Related Art Techniques for improving the design of an entire building by providing a structure and a design around the windows of the building different from those of the other outer walls have been often referred to as terracotta frames around the windows and have been widely used since ancient times. In Japan, many such window surrounding structures are being constructed along with the upgrading of buildings, but as the number of buildings using bricks increases, the demand for this so-called window terracotta is remarkable. is there. As a structure around a window (a terracotta frame around a window) of a building using bricks (tiles), the structure shown in FIG. 6 is conventionally known. FIG. 6 is a partially cutaway longitudinal sectional view showing a lower portion around a window, that is, a portion called a so-called face stand. In the drawings, 1 is a concrete frame, 2 is an outer wall tile, 3 is a window peripheral edge, that is, a window tile (brick) stretched on an outer edge and an inner surface of a window opening in the concrete frame. It has an L-shaped cross section. The outer wall tile 2 and the window tile 3 are stretched by mortar 4 on the concrete frame 1. Among them, the window tile 3 is fixed to anchor bolts embedded in the concrete frame 1 in order to prevent peeling. They are bound by a copper wire or the like (all not shown). Reference numeral 5 denotes a hardware for installing a window sash and the like, and reference numeral 5a denotes a sealing material. In this way, by providing a tile having a design different from that of the outer wall tile around the window of the building, a design accent is formed in the building.

[0003]

However, the above-mentioned prior art has the following problems. I. A so-called whitish phenomenon occurs around the windows, especially on the lower side, and the appearance of the building is significantly impaired. This efflorescence phenomenon is caused by rainwater that has infiltrated from the joints of
Outer wall tile 2 in lower part around window through mortar layer 4
It is caused by seeping out from the joint part of. That is, since the waterproof means is provided between the concrete skeleton 1 and the mortar layer 4, the rainwater that has entered from the window tile 3 of the face base passes through the mortar layer and passes through the joint of the outer wall tile 2. It will seep out. Then, the components in the rainwater combine with the salts while passing through the mortar layer to form CaCo _{3 and the} like, which oozes with the rainwater to the outer wall portion and causes the above-mentioned so-called efflorescence phenomenon. The efflorescence phenomenon is ultimately caused by the lack of waterproofing of rainwater around the window. B. It does not conform to the so-called dry construction method for brick (tile) laying. That is, in the brick (tile) stretching method, recently, special skill is not required, the construction period is short, the cost is low, etc.,
Various dry construction methods that do not use an adhesive such as mortar for stretching have been developed. The gist of this dry method is that a groove provided on the back surface of a brick (tile) is fitted to an engaging ridge formed on a wall surface of a building or a base substrate erected as a wall surface. Tiles).

However, since the above-mentioned prior art is a so-called wet method using mortar, there is an inconvenience that it cannot be adapted to a dry method in which bricks (tiles) are to be newly installed today. In other words, if the corners and outer walls were to be constructed by the dry method while the surroundings of the windows had to be wet, not only would the construction progress be poorly balanced, but the benefits of the dry method for the outer walls would be reduced by the wet method around the windows. There is a risk that they will end up.

[0005]

Means for Solving the Problems The invention according to this application is:
A window tile attached to cover a structure around a window of a building, particularly a building in which bricks (tiles) are stretched, from the outer wall end surface to the outer wall outer portion below the window opening;
A window tile which is fixed between the lower end of the window sash and the outer wall to hold the window tile fixedly, or which is attached to an end face of the outer wall above the window opening; And a holding bracket fixed between the outer walls and fixedly holding the window tile,

Alternatively, a window tile is attached to an end face of an outer wall at a side of the window opening, and a holding member is fixed between the window sash side end and the outer wall to fix and hold the window tile. Thus, the above-mentioned conventional problems are to be solved.

[0007]

In the window surrounding structure according to the present application, various fittings having a draining action between the end portion of the window sash and the end portion of the outer wall at the opening portion of the window are formed by various kinds of fittings and a window tile attached to the fitting. Because it is covered, it is possible to freely obtain a structure around the window with excellent design without fear of water leakage, and the so-called dry construction method that does not use mortar etc. Inexpensive costs are possible.
