Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a structure in which an exterior board is attached to the structural frame of a building. The present invention relates to a structure in which an exterior plate is formed by attaching the exterior plate by attaching the edge of the flexible board to a structural frame using screws and a presser metal fitting.

(Prior Art) In the exterior finishing work of buildings, the following two methods are often used to attach large exterior panels made of stone, ceramic, glass, etc. to the exterior walls of buildings.

One is the wet direct laying method. In this construction method, "Toro" is applied to the building structure, such as concrete walls.
This is a construction method in which the entire wall surface or strip is painted, and the exterior panels are pasted on top by hand, cutting out designated joints.

The second construction method is the so-called dry wall construction method. This method involves drilling grooves and dowel holes on the upper and lower ends of the exterior panels, inserting plates and pins between the grooves and dowel holes between adjacent exterior panels, and then attaching the plates and pins to shear connectors, etc. anchored to the wall. The exterior plate is attached by attaching the .

(Problem to be solved by the invention) In the wet direct-laying method, the exterior board and the wall are monolithically bonded, so if there is a difference in the coefficient of thermal expansion between the two, it will be difficult to solve the problem due to sudden temperature changes outside. Unable to absorb the displacement that occurs. As a result, a localized load is applied to the exterior plate itself, causing cracks. In addition, since most of the work is done by hand by pressing the exterior board into a "toro" shape,
Craftsmen are required to be highly skilled. Moreover, it requires a lot of construction time because it requires hardening and curing until a predetermined installation strength is achieved.

On the other hand, in the wall-to-wall construction method, it is necessary to drill grooves and dowel holes in the exterior board itself, and it is also necessary to attach anchors such as shear connectors to the wall surface, which requires a lot of work overall.

In addition, sufficient machining accuracy is required because it is impossible to insert the plate or pin unless the grooves and dowel holes provided in adjacent exterior plates are aligned with each other at predetermined positions.

Furthermore, if the plates, pins, and shear connectors are not attached accurately and reliably, joint cracks or cracks in the exterior panels themselves may occur during earthquakes, and ultimately the panels may fall off the wall surface.

As mentioned above, the two conventional construction methods have many problems not only in terms of construction length but also in terms of cost.

(Means for solving the problem) Therefore, the present invention was devised to solve the above problem, and the edge of the flexible board is made to extend and is lined with a decorative board material. The edges are attached to the structural frame of the building using screws and holding metal fittings, and by interposing a flexible board with lower rigidity between the decorative board material and the structural frame, the difference in displacement between the two can be compensated for by this flexible board. This provides a mounting structure that absorbs the heat and prevents the exterior plate from cracking or falling off.

(Example) Hereinafter, the mounting structure of the building exterior board of the present invention will be explained in detail based on the drawings.

FIG. 1 shows exterior plates 1, 1... arranged in the upper and lower stages.
...and the building structure frame 2, the holding fittings 3, and the screws 4, 4
It is a partially omitted exploded perspective view showing...

The exterior board 1 is formed into a so-called composite board by pasting together a decorative board 11 made of ceramic tiles or the like and a flexible board 12 made of an asbestos cement board or the like using an inorganic adhesive such as mortar or a rubber-based organic adhesive 13. It is something. In particular, the inorganic adhesive 13 such as mortar has excellent weather resistance and is therefore suitable for the exterior board.

For example, the size of the decorative board 11 is 592 x 592 mm and the thickness is 8 mm, and the size of the flexible board 12 is
600~600mm, thickness 8mm, at least 4mm
An exterior plate 1 having an extended edge 14 of about 100 to 100 mm is formed. When installing the exterior panels 1, 1, . . . , the rims 21 of the building structural frame 2 are arranged at intervals of 600 mm.

The exterior plates 1, 1, . . . are placed opposite each other on such a furring 21, and the upper and lower edges 14, 14 are butted against each other. Then, the presser metal fitting 3 is placed on the edges 14, 14 from the outside, and the screw insertion hole 31 drilled in the presser metal fitting 3,
Insert the screws 4, 4 into the holes 31 and screw them onto the rim 21. In order to screw the screws 4, 4, . Moreover, the insertion holes 31, 31 drilled in the presser metal fitting 3 have the same pitch as the semicircular notches 14a, 14a.

FIG. 2 is a schematic side sectional view showing the mounting structure.

That is, as mentioned above, the upper and lower exterior panels 1, 1
The edges 14, 14 of the flexible board 12 are attached to the flanges 21 by the presser fitting 3 via the screws 4, 4...
installed on. In other words, by fixing the flexible boards 12, 12 to the rim 21, the exterior panels 1, 1 are attached to the structural frame of the building.

As a result, the stress applied to the structural frame 2 of the building is absorbed and buffered by the flexible board 12, and is not directly transmitted to the decorative board material 11.

FIG. 3 is a schematic plan view of the exterior plate 1 mounted vertically and horizontally on the structural frame 2 of a building using the above-described mounting structure.

In addition, the size of one decorative board material 11 is 292 x 292.
mm, thickness 8 mm, and this decorative board material 11, 11, 1
It is also possible to form the exterior board 1 by pasting four pieces of 1... on a flexible board 12 with a size of 600 mm x 600 mm and a thickness of 8 mm, and attach this to the furring 21 provided with a span of 600 mm as described above.

That is, if the relative size of the decorative board material 11 and the flexible board 12 is such that at least the edge 14 is formed, it is possible to attach an appropriate number of decorative board materials 11 to one flexible board 12 in advance. Therefore, construction efficiency can be improved.

(Effects of the invention) As described above, the mounting structure of the building exterior board of the present invention allows the installation of the exterior board itself without using "Toro" to attach it directly or without using tenon processing or special mounting hardware. As a result, the following effects can be achieved.

The process of forming the exterior board from flexible boards and decorative board materials can be carried out in advance at a factory, etc., so exterior boards with a certain quality can be easily formed, and mass production is not limited to quality. As the size increases, it becomes possible to reduce costs. Moreover, since the exterior panels are attached using a so-called dry method, even if the exterior panels themselves are large in size, there is no need for a curing period, and the construction period can be shortened.

Since the presser fittings and screws are attached from the outside of the exterior plate, they can be easily removed from the outside, and the exterior plate can be easily replaced.

It can be attached to the structural frame of a building as long as it can be screwed with screws, and can be attached to structural frames such as PC concrete boards and metal frame panels if a rim is provided, so it has a wide range of applications.

If the screws can be accurately screwed into the structural frame, the exterior panels can be attached successively in sequence, so the skill level of craftsmen as required in the past is not required.
