Description

[Detailed Description of Device] a. Purpose of the invention [Industrial field of application] The present invention relates to the upright of the curtain wall forming the outer wall surface of the building, and the purpose of the invention is to obtain the upright which has an improved structure for introducing outside air to the supporting parts such as eyes and panels. To do.

[Conventional technology]

As the upright side of the curtain wall, a mounting base for the building body is provided at the rear of the central main wall, and a flange for panel locking is provided at the front to form a seamless space between them, and a face material fitting groove such as a panel or a ridge, A metal mold material having a projecting wall forming a gondola hanging guide groove portion for cleaning the panel on the front surface of the collar portion is usually used.

When the curtain wall is formed by using a proper packing and sealing agent for the panel, the ridge, etc., the edge of the panel etc. fitted in the groove for fitting the face material of the vertical and the vertical It is also common practice to form a space between the central main wall and the space to communicate with the outside air, and to make the pressure equal to the outside air pressure to enhance the sealing and waterproofing against wind and rain. In this case, a hollow portion is provided on the above-mentioned vertical central main wall at this time,
An outside air inlet is provided on the front side and an opening is provided in each side surface fitting groove to communicate the space with the outside air, and a watertightness is improved by using the central part as a drainage channel. It is shown in the publication.

[Problems to be solved by the invention]

In the cube shown in the above-mentioned publication, since the outside air introduction port provided in the front surface of the hollow portion of the central main wall is directly exposed and exposed to the outer surface, rainwater easily intrudes during wind and rain, and the face material fitting groove There is a problem that it may flow into the space of the room and cause water leakage to the room side, and that the temperature of the water flowing down the hollow section and the wind noise passing through the outside air inlet propagate to the room side and become noise. It was

Moreover, since rainwater, dust, etc. directly enter the cubic hollow part together with the outside air, the inner wall of the part corrodes relatively quickly,
There was a defect that shortened the service life of the curtain wall itself.

The cubic is usually an extruded aluminum material, and corrosion-resistant treatment such as electrolytic alumite treatment or electrodeposition coating is performed, but such means cannot be applied to the hollow portion, and the cubic is of sufficient practicality. Was hard to get.

B. Configuration of the Invention The present invention forms a hollow portion on the front surface of the vertical central main wall, which maintains good rainwater separation and drainage action and allows the face material fitting groove portion to communicate with the outside air, and thus the conventional problems described above. Is the solution.

That is, the present invention has a mounting groove at the rear of the central main wall and a flange for locking the panel at the front, and the guide groove formed by the side walls protruding forward from both sides of the flange, and the guide groove. A main body made of a mold material integrally provided with opposing protruding walls opposite to each other on the inner surface of the side walls, and the front ends of the flange portions, which are fitted between the opposing protruding walls and are spaced apart from each other in the longitudinal direction on both sides. A lid plate having a plurality of pawls that are erected so as to abut on the collar, and a hollow portion defined by the flange portion and the side wall, the opposing protruding wall and the lid plate, and the communication hole provided in the collar portion, and A curtain wall characterized by being able to ventilate with an outside air introduction hole provided in the side wall, and by providing a claw piece of the lid plate at a position facing the outside air introduction hole to serve as a suppressing plate for an inflow air flow. The idea is to stand upright.

In the above, the central main wall of the main body is plate-shaped, the mounting base of the rear part is usually a square tubular hollow in the part fixed to the building frame, but it is a plate-shaped body provided with an appropriate protruding piece part. The front flange may form a ridge at right angles to the central main wall, and there is no gap between the front edge of the mounting base and the rear edge of the flange on both sides of the central main wall. , It becomes a face material fitting groove such as a ridge.

Front sides of the parallel side walls projecting forward from both sides of the flange portion are opened in the longitudinal direction, and between the side walls form a guide groove for hanging a gondola for cleaning the outer surface of the curtain wall.

Opposed projecting walls are provided opposite to the respective inner surfaces of the standing side walls of the guide groove portion, and a lid plate is fitted between the open end edges of the guide projecting wall portion for sealing.

The lid plate has a strip-shaped face plate portion fitted between the end edges of the opposing projecting wall, a claw portion provided on both side edges thereof, and a claw piece that reaches the flange wall of the hollow portion through a step portion. A plurality of pieces are provided at intervals on both sides of the lid plate in the longitudinal direction.

A hollow portion is formed on the outer surface of the flange portion at the base of the guide groove portion by the flange portion, the side walls, the opposing protruding walls, and the lid plate fitted between the opposing protruding walls. Ventilation holes are provided on both sides of the central main wall and outside air introduction holes open on the side walls, and at least one of the claw pieces standing on both sides of the lid plate is an outside air introduction hole. It serves as a face-to-face airflow suppressing plate, and the space between the claw pieces serves as an air passage.

The above communication holes and the outside air introduction holes can be provided at least at the same level or at different levels in the longitudinal direction of the vertical seamless attachment interval, respectively, but different in order to improve the air-water separation action. It is desirable that the relative position is set so that the above-mentioned inhibition effect by the claw piece is effective.

[Action]

Since the upright of the present invention has the above configuration, the face material fitting groove portion of the curtain wall using this upright side is communicated with the outside air through the hollow portion located on the outer surface of the flange portion of the upright front portion to achieve an isobaric sealing action. As a result, good water-air separation is performed in the hollow portion, and the separated water flows down and is discharged in the hollow portion.

Therefore, the rainwater separating and discharging is performed outside the mounting face material, the infiltration into the face material fitting groove can be remarkably reduced, the indoor water leakage can be completely waterproofed, and the ventilation noise and water flow noise generated in the hollow portion Propagation is suppressed and a favorable living environment can be formed.

Further, even if corrosion occurs in the hollow portion, it has almost no effect on the cubic strength itself, and since the hollow portion is opened to the front when the lid plate is separated, the corrosion resistance against the vertical made of metal mold material is prevented. The treatment, for example, electrolytic oxidation alumite treatment and electrodeposition coating treatment on an aluminum mold material can be effectively carried out, and therefore, a cube of extremely high quality can be obtained for a curtain wall for a high-rise building where durability is particularly desired.
