Description

[Detailed description of the invention] This invention is capable of simultaneously and firmly holding two sashes that fit into a mullion from one side of a corner, and also allows a screwdriver to be inserted from the gap between the two sashes when holding the screws. It relates to a structure that allows insertion and screwing.

The details of the embodiments will be explained below with reference to the drawings.

The drawing is a cross-sectional plan view of a corner stand where two sashes whose intersecting angles are at right angles are fixed to the mullion.

Reference numeral 1 is a mullion in shape, which has a rectangular cylindrical cross section and is reinforced with a steel back plate 2. ) is welded to the reinforcing steel bar 3゜3, which protrudes from the top and bottom, and is supported and fixed between the top and bottom.

The symbol W in the figure indicates welding.

A slippery synthetic resin liner 4.degree. 4 of a desired thickness, such as hard vinyl chloride, is screwed in advance to two right-angled surfaces 1', 1' on which the sashes of the mullion 1 come into contact.

Note that holding grooves 10 for fixing the tight material 8 are provided at the outer ends of each of the two right-angled surfaces of the mullion 1 so as to extend through them in the vertical direction.

In the example, the mullion has an almost square cylindrical cross section, but it has a right angle 2
Other than this, there are no restrictions on implementation of the invention.

Reference numeral 5 denotes a clamping frame made of steel plate, the cross section of which is shaped like a channel, and one of the corresponding corners has a slit-shaped opening 5 in the vertical direction.
b, and the other side forms a corner surface 5a as a screw seat.

Note that the corner of the mullion facing the corner surface 5a also forms the screw holding surface 1a.

Numeral 6 is a plurality of screws, and by tightening the screws, both sides of the corner surface 5a of the clamping frame press two sashes 7, which will be described later, toward the outdoors.

7 is a sash that fits into the mullion from a perpendicular direction, and 7a is a flange 7a formed integrally with the sash and serves as a surface to which the decorative cover 9 is attached.

8 is made of tight material and is held and fixed in the holding groove of mullion 1.

Next, to outline the assembly process, the mullion 1, to which the back plate 2, liner 4, and tight material 8 are attached at the factory, is erected and fixed at the site by welding its upper and lower ends to reinforcing bars 3.

The corner surface 5a of the clamping frame 5 and the mullion-shaped screw holding surface 1a are temporarily fastened with screws 6 at the site.

Two sashes 7.7 are inserted between the tight member 8 and the clamping frame and abut against the liner 4.

Next, flange 7a, ? When a screwdriver is inserted between the holes 5a and 5b, and the temporarily screws 6 are fully tightened, the two sashes 7 are simultaneously attached to the clamping frame 5 and the tight material 8.
It is firmly held between

Finally, the decorative cover 9 is screwed between both flanges 7a.

It should be noted that the liner 4 is provided to provide a space between both flanges 7a to facilitate insertion of a driver, and the thickness of the liner 4 is adjusted according to the length of the flange 7a.

It is preferable to use extruded aluminum alloy for the mullion 1, the sash 7, the clamping frame 5, and the decorative cover 9, which are the constituent members whose materials are not specified among the above-mentioned constituent members.

Beautiful, rust-free and highly accurate component parts can be easily mass-produced, contributing to cost reduction.

According to the present invention, it is possible to very easily and easily fix two sashes in a one-sided corner by temporarily tightening the screws 6 from 90-degree different directions and firmly tightening them smoothly.
