DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for attaching a base material for an exterior material. Generally, a dry method using a tile, a metal panel, or the like as a design as an exterior material of a concrete structure is expensive in spite of its material cost. The reason is that the work of assembling a base such as a tile or a metal panel is complicated, time-consuming, and increases labor costs. Therefore, there is a demand for a development that provides a dry method at a low cost by simplifying the method of forming the base.

[0002]

2. Description of the Related Art Conventionally, when an outer wall of a concrete structure is made of a tile, a metal panel, or the like, the panel cannot be directly attached to the concrete because the outer wall of the concrete has irregularities. Therefore, a base such as a rim or a steel frame is required for the base. In general, there are two main methods for assembling the groundwork. The first method is to insert a rim support for attaching the rim to the skeleton using an anchor, etc., and adjust several bolts. (For example, Japanese Patent Publication No. Hei 8-9903, Japanese Patent Application Laid-Open No. Hei 10-88767, etc.) and the other method is to directly anchor the torso to the body while sandwiching a liner plate behind the torso. There is a method of fastening.

[0003] Both of these methods have the disadvantage that the work for drilling anchors and adjusting the level is troublesome, leading to an increase in cost. Further, there is a drawback in that the driving of the anchor leads to a cross-sectional defect of the skeleton, and the metal part serves as a cold bridge connecting the room and the outside, thereby causing dew condensation on the room side.

[0004] Therefore, there has been proposed a board supporting apparatus using a separator embedded in a concrete wall (Japanese Patent Application Laid-Open No. 8-189091). In the board supporting device, the body edge is used as in the related art. In the first place, the rim is used for fixing screws and bolts as a base material of the panel.

[0005]

However, so-called long objects such as steel channel steel and angle steel having a length of 3 m to 4 m have been used as the base until now.

[0006] The reason for this is that, for example, when a panel-like building member is fixed as seen from a floor structure in a wooden building, work is easily performed if there is a base material perpendicular to the member. It seems to be something. Indeed, in this method, once the heights (or access) of both ends of the member are determined, the height (or access) of the intermediate portion is determined, so that there are few mistakes in the work and easy.

[0007] However, when an exterior material is attached instead of a floor, there are some problems because the work place is at a high place. First, since the work place is on the scaffold, it is not easy to swing the long rim material. Inevitably, the work requires two or more people. A temporary stage for receiving the fringe material is required.

[0008] Further, in the mounting operation, various tools such as a hammer drill are required, and a welding operation may be required. If there is welding work, it is necessary to pay attention to the occurrence of fire, and it is necessary to cure the fire. When welding work is required, the worker must be a qualified person for welding work, and only some types of occupation work such as sash work can be performed.

At the time of concrete drilling, dust and noise are generated, which adversely affects the surrounding environment. Since the rim is made of metal, there is a risk of corrosion. It is also necessary to apply a rust inhibitor to prevent corrosion.

[0010] When the external heat insulation method is adopted, a cold bridge is easily formed in a metal portion. In addition, the support device for the board includes a base member screwed into the end of the separator,
In order to screw in the height adjusting member, the supporting device is attached following the concave portion formed by removing the P-con. However,
Usually, a concrete wall cannot be completely vertically driven due to a work error or the like, and a slope of about 10 mm often occurs at a height of 3 m. Therefore, the angle of the separator also has a slight angle compared to the horizontal. Therefore, there is a problem that if the outer wall material is attached using the support device directly attached to the separator, the outer wall material cannot be attached uniformly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to attach an outer wall material without using a rim and by absorbing a difference in irregularities of a concrete wall. It is an object of the present invention to provide a device and a method for mounting a base material for an exterior material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments shown in the drawings.

FIGS. 1 and 2 show an embodiment of an apparatus for mounting a base material for an exterior material according to the present invention (corresponding to claims 1 and 2). The mounting device 1 for a base material for an exterior material according to the present embodiment includes:
A support member 10 screwed to an end 32 of a separator 31 embedded in a concrete wall 30, and a base panel mounting member 20 locked to the support member 10 so as to be displaceable by a predetermined angle θ in the direction of its axis C. Consisting of

Here, the support member 10 includes a cone-shaped protrusion 11, a body 14 having an inner thread (for example, a trapezoidal screw) 15 provided on the inner wall surface and connected to the protrusion 11. It is an integrally molded product made of, for example, metal, synthetic resin, or the like, which includes an annular flange portion 17 provided continuously with the outer peripheral edge of the body portion 14.

The protruding portion 11 is provided at the end 32 of the separator 31.
An internal threaded portion 12 is provided at a predetermined length from the distal end face 13 along the axis C. The protruding portion 11 has an outer diameter substantially similar to the inner wall surface of the concave portion 33 formed by removing the P-con attached to the concrete wall 30. The body 14 abuts on the concrete wall 30 via a flat step 16 formed at a portion connected to the protrusion 11.

The flange portion 17 is connected to the base panel mounting member 20 by a fixing member. The flange portion 17 is provided on the support member 10 so that the mounting device 1 for the base material for the exterior material has the same performance as the body edge. The flange portion 17 has a function of deflecting the entire panel of the mounting device 1 for the exterior material base and a function of stopping the rotation of the base panel mounting member 20, and further enhances the pull-out resistance of the screw (fixing member) 45. did.

The base panel mounting member 20 includes a shaft portion 21 having several (for example, 1 to 3) outer screw portions 22 at its tip to be screwed into the inner screw portion 15 of the body portion 14, and the shaft portion 21. And a base mounting seat 23 having the same shape as the flange 17.
And a hemispherical recess 24 for inserting a tool 60 for rotating the base panel mounting member 20 provided at the center of the base mounting seat 23.

The outer screw portion 22 is not screwed tightly to the inner screw portion 15 like a normal screw, but is formed at a predetermined angle θ (for example, 10/300) with respect to the direction of the axis C of the support member 10.
0) Displaceably locked. Of course, the outer screw part 22 and the inner screw part 15 can advance and retreat along the screw part of the inner screw part 15 by rotating the outer screw part 22, and the outer screw part 22 can be stopped at the stopped position. And the internal thread portion 15 are engaged with each other at a predetermined interval.

Accordingly, the base panel mounting member 20 is formed by screwing the outer screw portion 22 into the inner screw portion 15 and
From the concrete wall 3
The support member 10 can be moved in the direction of the axis C in accordance with a vertical error of zero. The base panel mounting member 20 arranged at a predetermined position is a state in which the base panel for exterior material 40 is arranged on the base mounting seat 23, and
The exterior material base panel 40, the base mounting seat 23, and the flange 17 are integrally connected from the side via a fixing member 45 such as a screw.

The mounting device 1 for a base material for an exterior material has resistance to wind loads. When used in a building up to a height of 31 m, the maximum value of the wind load is as shown in Table 1.

[Table 1] Therefore, the wind pressure becomes maximum at the wall height of 31 m and 226 kg.
A wind load of a positive pressure of f / m ² acts. Here, the strength of the component is examined with respect to the value.

As shown in FIG. 3, the mounting pitch of the mounting device 1 for the base material for the exterior material is set to be 50 cm in length and width, and the screw (fixing member) 45 is inserted at the pitch. Screws (fixing member)
The pulling load received by 45 is (226/8) × 2 = 56.6 (kgf). Here, × 2 is a premium coefficient assuming that the load distribution is biased.

If the mounting device 1 for the base material for the exterior material is made of nylon 6, for example, the shear strength of nylon 6 is 560 kg / kg.
since it is cm ^2, and if the safety factor 3, the cross-sectional area in order to obtain the required shear force becomes (56.6 / 560) × 3 = 0.30cm 2. Assuming that the diameter of the screw (fixing member) 45 to be rubbed is M6, the required length of the hanging margin of the screw (fixing member) 45 is 0.30 / (π × (0.6 / 2) ² ) ≒ 1.1. (Cm).

Thus, it can be seen that if the total thickness of the flange portion 17 and the base mounting seat portion 23 is 1.1 cm or more, it can withstand a wind load. Next, a method of attaching a base material for an exterior material using the thus configured apparatus 1 for attaching a base material for an exterior material according to the present embodiment will be described (corresponding to claims 3 and 4).
First, a large number of separators 31 are arranged at equal intervals, for example, at a pitch of 50 cm, and concrete is poured into a concrete formwork.

Next, the concrete form is removed from the mold, and the P-con attached to the end 32 of each separator 31 is removed. Thereby, as shown in FIG. 3, the end 32 of each separator 31 is exposed from the concrete wall 30. Next, the support member 10 prepared so as to match the separator 31 is screwed with the end 32 of each separator 31 into the inner threaded portion 12 of the protrusion 11 and the protrusion 11 of the support member 10 is connected to the concrete wall 30. As shown in FIG. 2, a predetermined number of support members 10 are attached to the concrete wall 30 by being mounted in the recesses 33.

Next, as shown in FIG.
Base panel mounting member 20 prepared to match
Is inserted into the body 13 of each support member 10, and the outer thread 22 is screwed into the inner thread 152. At this time, the base panel mounting member 20 rotates the base panel mounting member 20 by inserting a tool 60 having a hemispherical projection 61 into the hemispherical recess 24 provided at the center of the base mounting seat 23.

This operation is performed while confirming the ingress and egress of the base panel mounting member 20 by a laser L transmitted from a black-out device (not shown) for transmitting a laser, which is installed below the concrete wall 30. At this time, for example,
If there is an error of 2 mm within the width of the P-con (= 27.5 mm), a 3 mm clearance is required for the straight surface correction (see FIG. 6).

Therefore, it is an important factor that the base panel mounting member 20 is displaced with respect to the support member 10 so as to follow the frame error. The displacement here is generally expressed as a tilt of about 10 mm at a height of 3 m. That is, the separator 31 is displaced at an angle of 10/3000 with respect to the axial direction of the separator 31 to correct the surface finish error of the concrete.

With the above, the mounting of the mounting device 1 for the base material for the exterior material according to the present embodiment is completed. Next, the exterior material base panel 40 is attached from below. However, the lowermost part and the uppermost part require a waistline. Here, the intersection of the four exterior material base panels 40 is the installation location of the exterior material base mounting device 1.

As shown in FIG. 5, while holding the flange portion 15 and the base mounting seat portion 23 by their upper sides by hand, for example,
A screw (fixing member) 45 is drilled into the base panel 4 for the exterior material.
Kneading from the 0 side toward the base mounting seat 23 and the flange 15. It should be noted that the rubbing of the screw (fixing member) 45 is stopped halfway, and the final final fastening is performed when the four exterior material base panels 40 can be installed.

Next, the dry tiles are mounted. As described above, according to the present embodiment, it is only necessary to provide the exterior material base mounting device 1 as a base only at the place where the exterior material base panel 40 is fixed, and it is possible to perform the construction in a simpler procedure than the conventional method. In contrast, the conventional method requires various tools such as a concrete drilling machine, a hammer, a spanner, and an electric screwdriver, whereas the present embodiment has a feature that the construction can be performed using only the electric screwdriver.

The mounting device 1 for the base material for the exterior material is made of a high-strength resin such as nylon 6, for example, and is mass-produced to reduce the unit cost per unit, thereby reducing the cost of the entire construction method. 1/7 of concrete
Since it has a thermal conductivity of about 1/5, it can also play a role in preventing cold bridges.
