Description

  The present invention relates to a continuous window. Specifically, the present invention relates to a continuous window having a plurality of glasses or shojis and having excellent fire prevention performance.

  Conventionally, as a window having a plurality of window portions, a continuous window in which two or more window portions are continuously provided in the left-right direction and a step window in which two or more window portions are continuously provided in the vertical direction are known. . FIG. 8 is an exploded perspective view showing a configuration of a conventional common window 80. In FIG. 8, for the sake of convenience, the shojis housed in the frame bodies 810 and 820 of the left and right window portions 81 and 82 are omitted. As shown in FIG. 8, the left and right window portions 81, 82 are each formed by a stand 83 constituted by a metal stand 831 on the outdoor side and a resin stand 832 on the indoor side through vertical frames 811, 821. Connected. That is, the vertical portion 830 that connects the left and right window portions 81 and 82 includes the vertical 83, the vertical frame 811 connected to the upper frame 812 of the window portion 81, and the vertical frame connected to the upper frame 822 of the window portion 82. 821 is configured by screwing.

  By the way, in recent years, an improvement in fireproof performance has been demanded for a window housed in an opening formed in a wall of a building. Therefore, for example, a technique is disclosed in which a lower frame reinforcing material having a substantially L shape in cross section is provided in the hollow portion of the lower frame (see, for example, Patent Document 1). According to this technique, when the fire breaks out, the lower frame reinforcing material receives the load of the shoji, so that the fall of the shoji is suppressed.

JP 2012-225149 A

  However, in the conventional common window shown in FIG. 8, in the event of a fire, each of the vertical 83 and the vertical frames 811 and 821 that are screwed together to form the vertical part is particularly in the in-plane direction (finding direction). There is a risk of warping and bending. For this reason, there is a possibility that the glass of the left and right window portions 81 and 82 may be cracked or a gap may be generated. Therefore, further improvement in fire prevention performance is desired. The same can be said for the corrugated window.

  Moreover, in the technique of patent document 1, although dropping of a shoji is suppressed by the lower frame reinforcing material, it cannot be said that sufficient fire prevention measures are taken, and further improvement in fire prevention performance is desired.

  The present invention has been made in view of the above, and an object of the present invention is to provide a continuous window having a plurality of glasses or shojis and having a fire prevention performance superior to conventional ones.

  In order to achieve the above object, the present invention provides a frame (for example, a frame (for example, left and right vertical frames 330 and 340 described later)) and a horizontal frame (for example, upper and lower frames 310 and 320 described later) (for example, A frame 30 described later, and a middle frame (for example, a partition that divides the frame into a first opening (for example, a first opening 10a described later) and a second opening (for example, a second opening 20a described later). A window 40 (for example, a window 1 described later), and at least one of the vertical frame and the horizontal frame (for example, a left vertical frame first hollow described later).

It is preferable to be divided into a second opening side core member (for example, a second upper frame core member 313b and a second lower frame core member 323b described later) arranged on the side.

In this invention, the core material is divided into a first opening side core material arranged on the first opening side and a second opening side core material arranged on the second opening side.
Thereby, for example, the first opening side core material and the second opening side core material are also applied to a single window having only a fitting window or a vertical extending window while maintaining the above-described improvement effect of fire prevention performance. Can be diverted. That is, according to this invention, versatility can be improved by dividing the core material into the first opening side core material and the second opening side core material.

Thereby, since a vertical frame, a horizontal frame, and a core material are mutually fixed by screwing etc., a deformation | transformation of the frame body at the time of fire outbreak can be suppressed more, and fireproof performance can be improved more.

  It is preferable that a metal middle frame core material (for example, a vertical core material 43 to be described later) extending in the extending direction of the middle frame is provided inside the middle frame (for example, a vertical hollow portion 41a to be described later). .

In the present invention, a metal middle frame core material extending in the direction in which the middle frame extends is provided inside the middle frame.
Thereby, since the curvature and bending of the connection part (standing part) comprised with a middle frame can be suppressed, fireproof performance can further be improved.

  The middle frame core material is preferably fastened together with the vertical frame or the horizontal frame core material.

In the present invention, the middle frame core material is fastened together with the vertical frame or horizontal frame core material.
Thereby, the deformation | transformation of the frame body at the time of fire outbreak can further be suppressed, and fireproof performance can further be improved.

  In addition, a frame (for example, a frame 30 described later) framed by a vertical frame (for example, left and right vertical frames 330 and 340 described later) and a horizontal frame (for example, an upper frame 310 and a lower frame 320 described later), An intermediate frame (for example, a vertical 40 described later) that divides the frame into a first opening (for example, a first opening 10a described later) and a second opening (for example, a second opening 20a described later); Are connected to the inside of the middle frame (for example, a vertical hollow portion 41a to be described later), a metal window extending in the extending direction of the middle frame. A frame core material (for example, a vertical core material 43 to be described later) is provided, and the middle frame core material is attached to the middle frame together with a glass holding metal fitting (for example, a first glass stopper metal 44 to be described later) adjacent to the middle frame. A continuous window characterized by being fastened together is provided.
