Description

[Detailed explanation of the idea]

Industrial Application Field The present invention relates to a windbreak room provided at the entrance of a building. Conventional technology Conventionally, a windbreak room was installed to block the air inside and outside a building and to help save energy.
It has the cross section shown in the figure. In other words, 1 in Fig. 1 is a windbreak room, in which sliding doors 2 and 2' are placed at intervals to block the air inside and outside the building, and a fixed wall 3 such as a glass plate is placed around them. This is what I did. Such a windbreak room 1 is a wall surface 4 of a building.
It is placed at a position that divides the opposite side of the square into two. Problems to be Solved by the Invention Therefore, the sliding doors 2 and 2' are arranged so that the areas formed by the lines perpendicular to their opening surfaces completely coincide and form a straight line, and
Since the distance between the doors is often not large enough, air will pass through when the sliding doors 2, 2' are opened and closed, resulting in insufficient air blocking. If the windbreak room 1 is sufficiently deep, the above-mentioned drawbacks can be solved, but since the capacity of the windbreak room 1 becomes large, a large amount of materials, space, etc. are required, which is not preferable. Means for solving the problem The present invention aims to improve this point, and aims to provide a windbreak room with a large air blocking effect in a small space. None, each side of the square is divided into two, one side is a fixed wall and the other is a door, and these fixed walls and doors are arranged alternately to create a windbreak room, where one diagonal of the square is the same as the wall of the building. This is a windbreak room characterized by being installed on the wall in a straight line. Example An example of implementation will be described based on the drawings.
The figure is a front view, and FIG. 3 is a horizontal sectional view. In the figure, 1 is a rectangular windbreak room, 2, 2', 2'' and 2 are sliding doors, 3 is a fixed wall, 4 is a building wall, 5 is a corner mullion, and 6 is an upper and lower stile. The room 1 is arranged so that one of its diagonals A is in the same straight line as the wall surface 4 of the building, and the sliding doors 2, 2', 2'', 2 are fixed to the mullion 5 and the upper and lower frames 6, respectively. It is provided between the fixed wall 3 and the mullion 5, and slides along the fixed wall 3. The sliding doors 2, 2' and 2'', 2 are provided at right angles to each other.In order to organize the traffic inside the windbreak room, planters etc. are placed on the floor of the windbreak room 1. The partition material 7 may be provided as appropriate. Also, a swing door or the like may be used instead of a sliding door. Effects of the invention In the present invention, the wind protection room has a horizontal section of a regular square, and one diagonal of the square is Because it is installed so that it is in the same straight line as the wall of the building, the entire surface of the windbreak room can be used, and the windbreak function is sufficient with a small capacity.Although theoretical analysis is difficult, configuring it this way makes it possible to As is clear from the experimental data that will be described later, this is one of the reasons why the present invention achieves its intended purpose.The doors in the windbreak room are arranged alternately with fixed walls. This reduces the amount of wind that directly passes through when opening and closing the door, improving the wind protection effect.This is because the entrance door of the conventional wind protection room
Since the areas formed by the lines perpendicular to the opening plane of each door are arranged in a straight line, the cross-sectional area of the area connecting the opening of one door and the opening of the other door is the area of the opening of the door. In contrast, the doors of the windbreak room of the present invention are arranged so that the areas formed by lines perpendicular to the opening plane of each door do not overlap, so that the opening of one door and the other The cross-sectional area of the area connecting the door openings is smaller than the cross-sectional area of the door opening surface, so the amount of air passing through the windbreak chamber of the present invention is smaller than that of the conventional one. It is estimated that This will be investigated through wind tunnel tests. First, in the typical conventional wind protection room shown in Figure 4, when the wind speed at the entrance door was 10.0, the wind speed at the exit door was 12.1. Next, when using the windbreak room of the present invention, in most cases there is one entrance door and one exit door, that is, two doors are opened and closed, and three or four doors are opened and closed at the same time. The frequency of opening and closing is extremely low.
Therefore, in this invention, as shown in Fig. 5, we take four typical examples of cases in which two doors open and close, and rotate them by 45 degrees to create the conventional structure, that is, the door and the wall of the building are parallel to each other. The windbreak rooms of both were compared. As a result of the test, the exit wind speed of each door was as shown in the table below. This test is shown as an average value based on three typical wind directions: the direction perpendicular to the building wall, and the left and right horizontal directions.

[Table] When the windbreak room of the present invention is actually used, the above-mentioned four types appear randomly, so their effects were examined by taking the average. As a result, it was found that the average value of the present invention was 9.6, which was superior to 10.9 of the comparative example. In other words, in the case of the comparative example in which the wall surface of the building and the diagonal line of the windbreak room are not on the same straight line, the exit wind speed is found to be inferior to that of the present invention even when the orthogonally opposing surfaces of the doors do not overlap. The effect of
