Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall material mounting structure, and more particularly to a wall material mounting structure in which the wall material is mounted to a building frame via a mounting bracket.

[Prior art]

Traditionally, in the mounting structure of wall materials in exterior wall construction, the fourth
Anchor bolts 22 embedded in the frame 21 as shown in the figure
Fix the angle 23 with a cross-sectional shape with a nut 2.4,
Insert the wall material 25 into the angle 23 with the insert pin 26
A structure in which the device is attached via a mounting bracket 27 or the like has been common.

However, this structure has an insert pin 2 on the end surface of the wall material 25.
It was necessary to drill a dowel hole 28 for inserting the hole 6.

Therefore, if the wall material 25 is a thin lightweight panel or the like, the diameters of the insert pin 26 and the dowel hole 28 must be made thinner, which weakens the strength and cannot be used in high-rise buildings. However, there is a problem in that the wall material 25 used in this mounting structure is limited to one having a certain degree of thickness.

Note that 29 is a bolt for tightening and fixing the mounting bracket 27 to the angle 23 in cooperation with the nut 30;
is a sealing joint between adjacent wall materials 25, 32
is lead for adhesion applied between the lower end surface of the wall material 25 and the mounting bracket 27.

On the other hand, in recent years, as a structure that can be used even in the case of thin wall materials 25 such as lightweight panels, the wall material 25 is fixed to the angle 23 fixed to the frame 21 in both upper and lower directions. A structure has been proposed in which the device is attached via attachment fittings 33, 34 or the like.

Here, to explain its structure, as shown in FIGS. 5 to 7, insert bolts 35 are buried in the upper and lower portions on both left and right sides of the back side of the wall material 25, and the base end portions of the insert bolts 35 is inserted into and supported in the support hole 36 of the insert pin 26 buried in the wall material 25 from the upper end surface or the lower end surface of the wall material 25.

The insert bolt 35 on the upper part of the wall material has an upper mounting bracket 33 having an approximately horizontal cross-section shape and having a downwardly bent part 37 and an upwardly bent part 38 formed at the tip thereof. The bent portion 37 of is fixed by a nut 39. On the other hand, a lower mounting bracket 34 having a clamping piece 40 bent downward is fixed to the insert bolt 35 at the lower part of the wall material by a nut 41.

The base end of the upper mounting bracket 33 is fixed to the angle 23 with a bolt 29 and nut 30, and the upper upward bending part 3 of the mounting bracket 33
The wall material 25 is supported and fixed to the frame 21 by being inserted and locked. Note that a back-up material 42 is provided between each adjacent wall material 25, and a sealing joint 43 is provided.

[Problem to be solved by the invention]

However, in the above mounting structure, it is necessary to bury the insert pin 26 in the wall material 25 and bury and fix the insert bolt 35 so as to insert it into the support hole 36 of the pin 26. On the other hand, since different types of mounting brackets 33 and 34 must be attached, the number of parts increases and the structure becomes complicated, resulting in problems in terms of material costs and work costs.

In addition, in the conventional mounting structure, when positive pressure is applied to the surface of the wall material 25 due to wind pressure or the like, the positive pressure is received by the insert bolts 35 and insert pins 26 inside the wall material 25. There was a problem in that damage such as cracks occurred.

This invention was made in view of the above-mentioned problems, and its purpose is to reduce the number of parts and simplify the structure, regardless of whether the wall material is thick or thin. You can reduce costs by
Furthermore, it is an object of the present invention to provide a wall material mounting structure that can prevent damage to the wall material even when positive pressure due to wind pressure or the like is applied to the surface of the wall material.

[Means to solve the problem]

In order to achieve the above object, the present invention has a bent part that comes into contact with the back surface of the wall material and a support part that comes into contact with the end surface of the wall material,
The gist thereof is to include a wall material having a mounting bracket that is attached to the frame and a locking portion that locks into the bent portion.

It should be noted that the bent portions were formed in pairs at the tip of the mounting bracket by bending them in both the up and down directions, and the supporting portion was similarly provided to protrude horizontally from the tip of the mounting bracket. It is preferable that

Further, the locking portion may be a locking portion exposed on the back side of the wall material of the locking metal fittings buried in corresponding positions on both the upper and lower ends of the wall material, and the locking metal fittings have the ends thereof Preferably, it is inserted into a mounting hole drilled in the end face of the wall material and fixed with an adhesive.

[Effect]

When the locking part of the wall material is locked to the bent part of the mounting bracket, the back side of the wall material will come into contact with the bent part, and the supporting part of the mounting bracket will come into contact with the end face of the wall material, and the wall material will be held by the mounting bracket. Supported.

When positive pressure is applied to the surface of the wall material, the positive pressure is received by the bent portion of the mounting fitting that comes into contact with the back surface of the wall material.

In addition, only one type of mounting hardware is used, making it easy to install the exterior wall.

Hereinafter, one embodiment embodying this invention will be shown in FIGS. 1 to 3.
This will be explained according to the diagram.

In FIG. 1, 1 is a concrete frame on which an outer wall is constructed, and 2 is anchor bolts buried in the surface of the concrete frame 1 at regular intervals. Reference numeral 3 designates an angle fixed to the anchor bolt 2 by a nut 4, and is formed in a cross section. Note that the angle 3 has a bolt insertion hole (not shown) formed therethrough.

Reference numeral 5 denotes a mounting fitting made of a flat plate made of stainless steel, and a long hole 6 is provided in the longitudinal direction approximately at the center of the base end. The mounting bracket 5 is tightened and fixed to the angle 3 through the elongated hole 6 by bolts 7 and nuts 8 so as to be adjustable in position in the front-rear direction (left-right direction in FIG. 1).

As shown in FIG. 2, on the right side of the distal end of the mounting bracket 5, there is formed a vertical piece 9 which is bent upward and has a predetermined width in the left-right direction. Similarly, a hanging piece 10 serving as a bent portion is bent downward. A projecting piece 11 serving as a support section is provided at the center of the tip of the mounting bracket 5 to protrude horizontally by a length corresponding to the thickness of a wall material 12, which will be described later.

The wall material 12 is made of a rectangular thin and lightweight panel, and a pair of lower mounting holes 13 corresponding to the width of the vertical piece 9 are bored on the left and right sides of the lower end surface of the wall material 12, respectively. Similarly, as shown in FIG. 3, a pair of upper mounting holes 14 corresponding to the width of the hanging piece 10 are formed on both left and right sides of the upper end surface of the wall material 12, respectively. In addition, as shown in FIG. 3, the lower mounting hole 13 and the upper mounting hole 14 are provided at positions shifted in the left-right direction corresponding to the positional relationship between the vertical piece 9 and the hanging piece lO in the mounting bracket 5. It is being

Further, reference numeral 15 denotes a fitting groove recessed from the opening end of each of the mounting holes 13 and 14 to the back side of the wall material 12.

16 is a locking fitting made of a stainless steel bar;
The proximal end portion is formed in a substantially U-shape, and the distal end portion thereof is bent at a right angle to have an L-shaped cross section. Then, the distal end of the locking metal fitting 16 is inserted into the mounting hole 13.14, the bent proximal end is fitted into the fitting groove 15, and the proximal end becomes the locking part 17. Wall material 12
It is adhesively fixed with an epoxy resin adhesive E that cures at room temperature in a state where it is exposed on the back side. By using the adhesive E, the locking fitting 16 is easily and firmly fixed to the wall material 12. The locking part 17 is formed to protrude horizontally from the back side of the wall material 12 by the thickness of the vertical piece 9 or the hanging piece 10 inserted, and is a locking metal fitting attached to the lower mounting hole 13. 16, a lower locking portion 17 corresponding to the vertical piece 9
The locking fitting 1 is configured with a and attached to the upper mounting hole 14.
6 constitutes an upper locking portion 17b corresponding to the hanging piece IO. 18 is a sealing joint provided between adjacent wall materials 12.

Now, the operation of the wall material mounting structure configured as described above will be explained.

First, the method for attaching wall materials will be explained.

As shown in FIG. 1, an angle 3 is tightened and fixed to an anchor bolt 2 of a concrete frame 1 using a nut 4 so that the surface that overlaps with the base end of the mounting fitting 5 is horizontal. Then, the wall material 12 to be attached below the angle 3 (hereinafter referred to as "lower wall material 12J") is arranged so that its upper locking part 17b corresponds to the tip of the angle 3. Angle 3 the base end of metal fitting 5
When the hanging piece 10 of the mounting bracket 5 is engaged with the upper locking part 17b, the outer surface of the hanging piece 10 comes into contact with the back surface of the lower wall material 12. Then, align the elongated hole 6 of the mounting bracket 5 with the hole insertion hole of the angle 3, and
When the base end portion of the wall material 12 is tightened and fixed to the angle 3 with the bolt 7 and nut 8, the upper part of the wall material 12 is positioned by the hanging piece 10 in the left-right direction and the front-rear direction.

Next, a wall material 12 (hereinafter referred to as "upper wall material 12") is placed above and adjacent to the lower wall material 12 on the vertical piece 9 of the mounting bracket 5.
When the lower locking portion 17a of the upper wall material 1 is engaged, the upper wall material 1
The outer surface of the vertical piece 9 is in contact with the back surface of the upper wall material 1
2, the lower part of which is positioned in the left-right direction and the front-back direction. At the same time, the lower end surface of the upper wall material 12 comes into contact with the protruding piece 11 of the mounting bracket 5, and the weight of the upper wall material 12 is supported by the protruding piece 11.

In this state, when positive pressure is applied to the surfaces of the upper and lower wall materials 12 due to wind pressure or the like, both wall materials 12 are pressed in the direction of the arrow in FIG. Weight is applied to the outer surfaces of the upright piece 9 and the hanging piece 10 that abut against both pieces 9. Positive pressure against both wall materials 12 is received by the entire outer surface of IO.

As described above, according to the wall material mounting structure of this embodiment, unlike the conventional case, the wall material 12 can be mounted with only one type of mounting bracket 5, and the wall material 12 has mounting holes drilled on its upper and lower end surfaces. It is only necessary to adhesively fix the locking metal fittings 16 to the holes 13 and 14, and there is no need to bury the insert pin 26 and further bury and fix the insert bolt 35 so as to insert it into the support hole 36 of the insert pin 26. Regardless of whether the wall material 12 is thick or thin, the number of members can be reduced, the structure can be simplified, and material costs and work costs can be reduced.

Moreover, unlike the conventional case, the positive pressure applied to the wall material 12 is received by the entire outer surface of the vertical piece 9 and the hanging piece IO that contact the back surface of the wall material 12, instead of by the insert bolt 35 and the insert pin 26. Therefore, no cracks or the like occur in the wall material 12, and damage to the wall material 12 due to wind pressure or the like can be reliably prevented.

Moreover, since the weight of the wall material 12 can be supported by the projecting piece 11, the wall material 12 can be stably supported without putting any burden on the locking portion 17.
2 can be supported and fixed, and the horizontal line of the wall material 12 can be aligned using the projecting piece 11.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, the locking fitting 1 may be replaced by filling the mounting hole 13.14 with a rubber tube instead of the epoxy resin adhesive E.
6 may be fixed, or the number of attachment points for the locking fittings 16 may be increased depending on the size of the wall material 12. Also, wall material 12
Vertical piece 9 and hanging piece I that come into contact with the back surface or lower end surface of
If a cushioning material made of synthetic resin or the like is attached to the outer surface of the O or the upper surface of the protruding piece 11, even if the contact surfaces of these slide against the wall material 12 due to an earthquake, etc., the wall material 1 will remain intact.
2 is not damaged and can prevent rattling or the like from occurring in the mounting structure of the wall material I2. Furthermore, by forming the vertical piece 9, the hanging piece 10, and the protruding piece 11 on the tip of the angle 3 and using the angle 3 as the mounting bracket 5, the number of parts can be reduced. Any changes can be made without departing from the spirit.

〔Effect of the invention〕

As described in detail above, the present invention can reduce the number of parts and simplify the structure, reducing costs in terms of materials and work, regardless of whether the wall material is thick or thin. This has an excellent effect of preventing damage to the wall material even when positive pressure such as wind pressure is applied to the surface of the wall.
