Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a wall dungeon in which a window frame is formed between plate-like panels made of lightweight aerated concrete or the like in a continuous window manner, and which can be constructed in a short time and at low cost. This paper relates to a method for composing walls of buildings for the purpose of

[Prior Art] In general, a wall surface formed using a large number of panels is manufactured in such a way that the panels and the parts to which they are attached are mass-produced as standard products at a factory, and the panels can be easily assembled using these parts. Because they are pre-designed, they can be constructed in a relatively short period of time, and are mainly used for buildings such as factories.

The walls are provided with windows for lighting, ventilation, etc., as necessary, to brighten the room, purify the air in the room, and improve the indoor environment.

In order to form the above-mentioned walls and windows, for example, a large number of columns forming the structural frame of a building are horizontally supported by beam members supporting the floor surface of each floor, and the front surface of the horizontally supported beam members is A known construction method is to form a wall surface by attaching rectangular plate-like panels horizontally to a wall and providing a horizontal row of openings where the panels are not present at desired positions. In this conventional construction method, as shown in the vertical cross-sectional view of the opening 5 shown in Fig. 2, horizontal steel frames 6.6 made of angle materials or the like are first attached to the upper and lower surfaces of the stacked plate panels 3.3. At the same time, the steel frame 6.6 is fixed to the column 1.1 by welding, bolts, etc.

Next, an anchor 8 is welded to the horizontal steel frame 6 below the opening 5 via a round bar with a diameter of about 10 mm to increase strength. The lower frame 7b of the window frame 7 is attached to the anchor 8. Similarly, the anchor 8 attached to the upper frame 7a has a diameter of LO.
A window frame 7 is attached within the opening 5 by welding to the horizontal steel frame 6 above the opening 5 via a round bar of approximately 1.5 mm in diameter. The space formed between the plate panel 3 and the window frame 7 and other spaces 9
Then, finishing work such as filling with mortar 9a is performed to form the wall surface and window frame.

The above-mentioned FIG. 2 is a cross-sectional view corresponding to the a-a line cross section of the wall surface of FIG. 1 constructed according to the present invention.

[Problems to be Solved by the Invention] However, in the conventional construction method described above, the entire window frame 7 to which the anchors 8 are attached in advance is built, so the positioning for welding the anchors 8 to the horizontal steel frame via round bars is difficult. On-site work such as welding and welding requires a lot of effort, and since welding sparks are generated, safety measures such as fire prevention are required, and the space 9 between the panel 3 and the window frame 7 is filled with mortar 9a. Therefore, it is necessary to perform on-site work such as crossing the mortar 9a and filling and finishing the mortar 9a.
There was a problem that curing was required, which required a long construction period, and as a result, on-site work became complicated and expensive. In addition, window frames 7 installed using conventional methods
is fixed to the horizontal steel frame 6.6 via an anchor 8.8, but it is not connected to the panel 3.3, and since the bending elastic modulus of these members is different, it will not work in the event of strong winds or earthquakes. , when these members are bent and deformed by external force, the mortar 9a and the horizontal steel frame 6 slide sideways against the panel 3,
There was a problem in that gaps were formed between these, causing water leakage. - [Means for Solving the Problems] The present invention has been made in view of the above circumstances, and includes stacking rectangular panels horizontally to form a wall surface, and
An opening long enough for a plurality of windows to be lined up horizontally in a horizontal row is provided in the wall, and anchor rails are screwed directly to the end faces of the panels above and below the opening. By fixing the window frame between the anchor rails and directly supporting the window frame on the panel, the horizontal steel frame seen in the conventional method is not required, and the horizontal steel frame seen in the conventional method is To provide a method for constructing a wall surface of a building, which makes it possible to construct a wall surface having a large number of consecutive windows in a short period of time and at low cost.

That is, the present invention stacks rectangular panels horizontally in the vertical direction on the front of pillars vertically erected at appropriate intervals, and also creates a horizontal row of long openings in which windows are lined up in a row between the panels.

The vertical frames 31 are connected to each other via a continuous window mullion 33.

In this way, the window frames are installed in a row of windows. The continuous window mullion part 33 is a so-called middle mullion of connected windows. The mullion part 33 shown in the drawing includes a bracket 33a, a plate body 33b, and an L
It consists of cedar boards 33c, etc., and is attached as follows. First, brackets 33a are screwed to the upper and lower ends of both sides of the back surfaces of the vertical frames 31, 31 of the window frame 30, and a plate body 33b extending through the entire length in the vertical direction is screwed to the brackets 33a. A cedar board 33c is passed through the entire length in the vertical direction.

In this way, the present invention stacks rectangular panels horizontally in the vertical direction on the front of pillars vertically erected at appropriate intervals, and also stacks a horizontal row of long windows in a row between the panels. An anchor rail having an approximately L-shaped cross section is directly screwed to the lower end surface of the upper panel and the upper end surface of the lower panel of the opening, and a window frame is further screwed between the anchor rails. The present invention is a method for configuring a wall surface of a building having a continuous window section, and the present invention is a method of forming a wall surface by stacking a large number of panels while providing appropriate openings according to the above method, and supporting a window frame on the panel. A window is formed in the opening to constitute a wall surface of a building having a continuous window section exhibiting an appearance as shown in FIG. 1 or FIG. 5.

Additionally, interior construction work inside the building will be carried out as necessary.

[Effects of the Invention] As explained above in detail, the method of configuring the wall surface of a building having a continuous window section according to the present invention uses the existing methods such as welding for attaching members (current methods refer to In cases where the installation relationship of each component is not clear, we design the installation relationship of window frames etc. in advance, instead of using the process of processing and installing each component on site.
Since it is manufactured, it is easy to install the window frame and does not require skill, and there is no need for safety measures to prevent fires caused by welding sparks, which significantly reduces labor on site. The conventional process of filling with mortar can be eliminated, and the construction period can be shortened and walls of buildings with continuous windows can be formed at low cost.

In addition, in the present invention, the window frame is directly screwed to the panel via the anchor rail, and these are directly joined. Therefore, the positional relationship of installation,
For example, the positional relationship between the window frames can be adjusted by adjusting the gap between the bolt holes and the bolt outer diameter, and the wide bottom of the anchor rail, which has an approximately L-shaped cross section, can be used to adjust the position of the window frame. It also has the construction advantage of being able to be stably supported.

In addition, in the wall surface of a building having an opening where windows are lined up horizontally in a continuous window state obtained by the present invention, the window frame is directly screwed to the panel via an anchor rail, and these are directly joined. Therefore, in the event of strong winds or earthquakes, these elements collectively resist bending deformation, preventing gaps from forming between the panel and window frame and preventing rainwater from entering through the gaps. If it is formed into a roughly L-shaped cross section with inner and outer flanges with long and short rail legs, it is possible to suppress the vibration of the window due to wind pressure, etc., and the wide bottom of the anchor rail can stably support the window frame. This has the effect of allowing the window frame to be installed straight and easily by placing one end of the window frame on the projecting piece of the anchor rail from the outside of the room, and since the inner flange has long legs, it is possible to prevent rainwater from entering. It has this effect. Of course, it goes without saying that the panel surface in which the rectangular panels are stacked horizontally and the continuous window section arranged horizontally create a harmonious appearance.
