Description

[Detailed explanation of the invention] This invention is based on the structure of the frame material of the satsushi that is attached to the outer wall of a building. Concerning mullion fixtures that are installed to prevent! It's a good idea.

At the opening in the exterior wall of a building, a frame material for attaching a glass shoji or the like is attached to the opening in the exterior wall of a building. An intermediate mullion that connects the lower frame or a matching mullion that connects the upper and lower frames is installed to fit one of the two shoji and form a mating part with the other shoji that can be opened and closed. Very often.

b) Regarding such openings in the exterior wall, when the concrete exterior wall is formed when constructing a building, a frame material is attached to the opening and construction progresses. Therefore, it takes a long time to solidify.The concrete that makes up the outer wall continues to solidify even after the sash component frame material is installed, and if the outer wall bends due to the deformation of the concrete during solidification, the deformation will cause the concrete to solidify. Pressure is applied to the upper frame of the component frame materials, and the mullions supporting the upper frame in the middle, such as open mullions and combined mullions, may be compressed and deformed. If the outer wall develops cracks and deforms over time, the mullion will be compressed due to the deflection of the upper frame of the sash structure frame material, which is compressed due to the sag. In addition to deformation and deformation, even when a mullion expands thermally, compressive force acts on the mullion and deforms it, and there is a need for measures to prevent such compressive deformation of the mullion. .

The present invention solves this problem, and the mullion that connects the upper frame and lower frame of the satsushi component frame attached to the opening of the external wall of the building in the middle prevents the deflection of the external wall and the mullion. In order to prevent compressive deformation due to thermal expansion, etc., the upper frame of the sash component frame material or the mullion, etc. To provide a mullion fixing tool that relieves the force applied to the upper frame material of the mullion so that it does not directly act on the mullion, and also relieves the force applied to the mullion even if the mullion thermally expands.

More specifically, the present invention has a mullioned fixing part protruding at right angles from the center of the surface opposite to the surface that contacts the upper frame of the upper frame fixing part which has attachment parts to the upper frame at both ends. The spinning mullion fixing part is formed with a threaded part into which a set screw is inserted through a loose hole drilled in the end side of the mullion. This invention relates to a mullion fixing tool, characterized in that a spacer made of an elastic material is attached to the vicinity of the protrusion of the mullion fixing part of the fixing part, with which the upper end of the mullion is brought into contact.

-,j Hereinafter, one embodiment of the mullion fixing tool according to the present invention will be described in detail with reference to the drawings.

Fig. 1 is a front view of one embodiment of the mullion fixing tool according to the present invention, Fig. 2 is a plan view thereof, and Fig. 3 shows how the mullion fixing tool according to the present invention attaches a mullion to a sash component.

FIG. 4 is a sectional view of the upper frame member seen from below, showing the attached state; FIG. 4 is a sectional view taken along the line A--A in FIG.

In the drawing, 1 is the upper frame member 4 of the frame members with sash components at both ends.
The upper frame fixing part 1 has an attachment part 1a to the upper frame fixing part 1, and a set screw 7 such as a countersunk screw for attaching the upper frame fixing part 1 to the upper frame material 4 is inserted into the attachment part 1a of the upper frame fixing part 1. A hole is drilled.

Reference numeral 2 denotes a mulloidal fixing portion that projects at right angles from the center of the surface of the upper frame fixing portion 1 opposite to the surface that contacts the upper frame member 4;
The mullion fixed portion 2 is formed with a threaded portion 2a into which a set screw 6 is inserted through a loose hole 5a formed in the end side of the mullion 5.

This mullion fixing part 2 may be integrally molded with the upper frame fixing part 1, or may be connected and fixed by means such as welding or screwing, and when the mullion fixing part 2 is made of aluminum material The threaded portion 2a does not need to be formed with a female thread, since it is sufficient that a set screw 6 made of a tapping screw is threaded into the threaded portion 2a.

3 is a mullion fixed part 2 protruding at right angles from the center of the upper frame fixed part 1, giving it a T-shape; This is a spacer made of an elastic material such as rubber, with which the upper end of the spacer 5 is brought into contact.

To attach the mullion 5 to the upper frame member 4 using the mullion fixing tool according to the present invention having such a structure, first attach the sash component frame member 1 to the opening in the outer wall of the building, and then attach the upper frame member 4 to the upper frame member 4. Bring the contact surface of the upper frame fixing part 1 against the upper frame material 4 into contact with the mullion mounting location on the lower surface of the , and then insert the setscrew 7 into the screw hole drilled in the mounting part 1a to fix it. Attach screw 7 to upper frame material 4
Screw it on.

Next, the upper end of the mullion 5 is fitted around the mullion fixing part 2, and the upper edge of the mullion 5 is brought into contact with the spacer 3; mullion 5
The fixing screw 6 can be screwed into the threaded portion 2a of the mullustral fixing portion 2 by inserting it through a Reuleaux hole 5a drilled in the side surface of the end portion.

In this operation, a loose hole 5. is drilled in the end side of the mullion 5. a is larger than the diameter of the set screw 6 and the set screw 6
If the hole is a round hole with a smaller diameter than the bright part of
In the case where the hole is a long hole extending in the longitudinal direction of the mullion 5, it is necessary to operate the set screw 6 by aligning the set screw 6 well with the threaded portion 2a of the mullion fixing part 2.

When the upper frame material 4 and the mullion 5 are fixed by the mullion fixing tool according to the present invention in this way, the outer wall of the building,
If the concrete is deformed or bent during the solidification process and the upper frame material 4 of the sash component frame material is pressurized or the mullion 5
When the length increases due to thermal expansion and the force acting on the mullion 5 is small, the force exerted on the upper frame member 4 is supported by the mullion 5 as in the case of conventional mullions, and the I hear it.

Frictional resistance due to the tightening force of the setscrew 6 inserted through the loose hole 5a drilled in the end side of the mullion 5 and screwed into the threaded part 2a formed in the mullion fixed part 2 The positional relationship between the frame material 4 and the mullion 5 cannot be maintained in the same state as before when no force is applied, and the set screw 6 moves downward along with the mullion fixing part 2 along the loose hole 5a of the mullion 5. , the spacer 3 is deformed by the movement, but within the range where the spacer 3 can be compressed and deformed, the mullion 5 directly touches the upper frame member 4.
Since only the deformed portion is not deformed and the force is relaxed, the mullion 5 becomes difficult to compress and deform.

In order to further promote such an effect, it is possible to provide a notch in advance on the side of the upper frame member fixing portion 1 that contacts the upper frame member 4 and to reduce the thickness between the mounting portions 1a. In addition to the allowable amount of compressive deformation of the spacer 3, the upper frame member fixing portion 1 can be further deformed by the gap created by the notch between it and the upper frame member 4, so that even larger deformations of the upper frame member 4 can be avoided. Compressive deformation of the mullion 5 can be prevented.

As detailed above, the mullion fixing tool according to the present invention is used to connect the upper frame material 4 of the sash component frame material and the mullion 5, and is used to connect the mullion 5 to the upper frame material 4 of the sash component frame material, and is used to connect the mullion 5 to the upper frame material 4 of the sash component frame material. The force applied to the upper frame member 4 due to the resulting deflection and the force generated due to the thermal expansion of the mullion 5 act directly on the mullion 5.
It plays the role of alleviating the force of concrete so that it does not undergo compression deformation, and can be used not only for newly constructed buildings but also for buildings that have been constructed for many years.As a result, only the deformation of the outer wall due to solidification of concrete To alleviate the compressive deformation that acts on the mullion 5 even when the outer wall is deformed due to cracks or the like after construction or when the length of the mullion 5 becomes longer due to thermal expansion. Because of its simple structure, it has the excellent advantage of being inexpensive and easy to manufacture, as well as being easy to install, and has great practical value.
