Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a furring strip mounting structure that can be mounted easily, quickly, and firmly without using fasteners such as bolts.

[Conventional technology and its problems]

Conventionally, a wall provided with a heat insulating material usually has a structure in which a relatively thick glass wool, wood wool board, or other heat insulating material is sandwiched between a structural material such as a stud and a furring strip. Was there. Further, in order to form a void (air layer) on the outer side of the heat insulating material, it is necessary to easily attach the furring strip, but in this case, it could not be easily attached. In other words, because of the presence of heat insulating material, it is not possible to fix the furring strip while welding sparks, etc.
Fixing the furring strips with nuts was also troublesome, and there was a problem that construction efficiency declined.

Further, if the furring strip is fixed with a screw or the like and the screw portion or the nut of the shaft rod projects from the surface of the furring strip, there is a disadvantage that the outer wall finish becomes inconvenient.

[Means for Solving the Problems]

Therefore, as a result of earnest and repeated studies to solve the above-mentioned problems, the inventor provided the present invention with a trapezoidal enlarged tip portion on the constricted side of the substantially C-shaped support arm portion, which is a strip plate. A support rod having bent mounting members provided at predetermined intervals, a heat insulating material sandwiched and fixed to the structural material via a long-axis bolt between the support rod and the structural material, and both end portions of the coronal portion. Fasteners such as bolts are used by having a furring strip mounting structure in which the furring strip is formed inwardly with a fitting folded edge, and the furring strip is fitted on the enlarged front end portion of the mounting bracket. The present invention solves the above-mentioned problems by being able to easily, quickly, and firmly attach the device.

Reference numeral 4 is a structural material such as a stud or the like. Reference numeral 5 denotes a long shaft bolt, the base portion of which is fixed to the structural member 4, and the distal end side of the long shaft bolt 5 is threaded with a screw portion 5a. 6 is a heat insulating material such as wood wool board, foam synthetic resin, rock wool,
A reinforcing plate 7 is attached if necessary. Its insulation 6
Are provided so as to cover the outer surface side of the structural members 4, 4, ..., At this time, the screw portion 5a on the tip end side of the long shaft bolt 5 is configured to project. More specifically, the threaded portion 5a of the long shaft bolt 5 protruding from the heat insulating material 6 is passed through the mounting through holes 1a, 1a, ... A plurality of the support rods 1 are fixed to the structural member 4 substantially in parallel with each other at appropriate intervals. As shown in FIG. 3, the furring strip 3 is fitted on the mounting bracket 2 such that the longitudinal direction of the furring strip 3 is substantially orthogonal to the support rod 1 with the mounting bracket 2, and the furring strip 3 is strongly attached. Pressed and mating folded edge 3b, 3b
Is fitted to the fitted parts 2b ₁ and 2b _1, and the attachment of the furring strip 3 is completed.

Reference numeral 8 denotes a wall material, which is attached to the furring strips 3, 3, ... With a drill-like fastener. As a result, a substantially sealed air layer 9 is formed between the wall material 8 and the heat insulating material 6.

In the above description, the structural member 4 and the furring strip 3 are substantially vertical, but the structure is not limited to this.
The furring strip 3 may be provided in a substantially horizontal shape.

[Effect of device]

In the present invention, a trapezoidal enlarged tip portion 2b is provided on the constricted side of the substantially C-shaped support arm portion 2a, and these are supported by mounting fittings 2 formed by bending a strip plate at predetermined intervals. Rod 1
A heat insulating material 6 sandwiched and fixed to the structural material 4 via a long shaft bolt 5 between the support rod 1 and the structural material 4 and fitting folding edges 3b, 3b inward from both side ends of the coronal portion 3a. By forming the furring strip 3 including the formed furring strip 3 and fitting the furring strip 3 on the enlarged tip portion 2b of the mounting bracket 2, first of all, the furring strip is easily and quickly mounted. The second effect is that it can be relatively firmly attached, and the third effect is that the outer wall can be easily finished.

These effects will be described in detail. In the structure in which the heat insulating material 6 is provided on the wall portion, and the heat insulating material 6 is sandwiched between the structural material 4 such as a stud and the furring strip 3, in the conventional case, , Fixing shaft rods to structural members such as studs, and fixing the furring to these shaft rods by welding, or forming a screw portion at the tip of the shaft rod,
Although it could be done only with a troublesome thing in which the furring strip is fixed with bolts, nuts, etc., in the present invention, the supporting rod 1 with the mounting bracket 2 has the mounting brackets 2, 2 ,. The furring strips 3 are provided at intervals, and the folded edges 3b, 3b of the furring strip 3 are formed more inward than the end edges of both sides of the coronal portion 3a. _Since the furring strips 3 are fixed by fitting to ₁ , 2b _1, after the supporting rod 1 with the mounting bracket 2 is fixed to the structural member 4 such as the stud via the long shaft bolts 5,
The furring strip 3 can be attached without using bolts, nuts, welding, etc. Moreover, since the furring strip 3 is fitted to the mounting brackets 2, 2, ... This is extremely simple and quick compared to the conventional one. Further, since the welding is not used in the attachment of the furring strip 3, no thermal strain is generated in the furring strip 3, and when the heat insulating material 6 is used, the heat of the welding damages the heat insulating material 6. There is also an advantage that the heat insulating effect of the heat insulating material 6 can be favorably maintained.

Next, the furring strip 3 is bent inward from the end edges on both sides of the coronal portion 3a to form the fitting folding-back edges 3b, 3b, so that the fitting folding-back edges 3b, 3b of the furring strip 3 are formed. When fitting and fitting to the mating parts 2b ₁ and 2b ₁ of the mounting bracket 2, the fitting folding edges 3b and 3b
Bites into the fitted parts 2b ₁ and 2b ₁ and becomes a so-called fit-in state, so that extremely strong attachment can be achieved.

Next, fasteners such as bolts and nuts are not used for attaching the furring strip 3 at all, so that there is no protrusion from the surface of the furring strip 3 and the like. The outer wall can be easily finished and the construction efficiency can be improved.

As described above, since the furring strip 3 can be attached easily, quickly, and firmly, when the wall member 8 is attached to the furring strip 3, 3, ..., The furring strip 3 is substantially sealed inside the wall member 8. The heat insulating wall in which the air layer 9 is formed is configured, so that a so-called heat insulating wall having good external heat insulation can be provided.
