Description

Construction structure of internal and external stone panels in buildings}

The present invention relates to the construction structure of the stone panel for interior and exterior of a building, and more specifically, to produce a thinner and wider stone panel widely used as interior and exterior materials of a building, the frame joining grooves are continuously formed on the slope of the stone panel. By combining and fixing the outer frame extruded with aluminum, it is possible to greatly reduce labor and construction costs in accordance with the interior and exterior construction of the building by manufacturing a stone wall unit for curtain wall-like building and exterior wall forming. It can save resources, lighten the building, prevent damage to the building structure itself, greatly reduce the air of the new building itself, and manufacture the stone panel unit itself in the factory. Therefore, it is possible to prevent dust generation and industrial waste generation at new construction sites, and to install scaffolding during construction. Of course, it is not necessary that the post work is not necessary, such as welding, etc., and the invention is not required after work such as washing the stone after construction.

Recently, as a finishing material for the interior and exterior walls of buildings such as high-rise buildings, stone panels, such as marble or granite, which are processed into square flat plates, have been adopted.

Such a stone panel is continuously attached vertically and horizontally to enhance the appearance of the building, and various structures for attaching such a stone panel to the building have been proposed in the past.

Installation methods of such stone panels include a wet method and a dry method.

In the above method, the wet method is a method in which mortar is filled between the structure and the stone, and it is integrated with the connecting hardware, and it is used for laying internal and external low walls, flower beds, and floors. It is reliable, it needs mortar hardening time, it is difficult to install in winter, and there are advantages and disadvantages of whitening phenomenon when rainwater infiltrates.

The dry method can be installed in winter, there is no whitening phenomenon with the air shortening, the upper load is not transferred to the lower side, the heat insulation effect and the condensation prevention effect is large, but it is weak to impact, and there is a risk of rust in long-bonded steel and weight It is heavy and requires the use of both heavy equipment and relatively expensive (wet) compared to the wet method, there is the following method of fixing the stone using the dry method.

The first method is the anchor anchoring method, which attaches unit stone to the wall of the building one by one with anchor hardware. The plate thickness of the stone is limited to 30mm, which is likely to damage due to impact. The upper load is not transmitted to the lower part and rust prevention of anchor hardware is required.

Secondly, there is a steel truss support method. It is easy to construct a joint joint by attaching several pieces of stone plate to the pre-assembled truss on the ground and then attaching the panel using a heavy lifting machine. In addition, it is possible to shorten the air by the large-scale construction, large heavy equipment is needed, and steel truss stiffness needs to be examined.

Thirdly, there is the GPC method, which is a method of assembling the slab on the back of the PC to assemble it into a PC, which is produced at the factory, which has the effect of shortening the air, and the thickness of the stone can be made thinner. The disadvantage is the need for large lifting equipment.

The method for installing the stone panel used as a building interior and exterior barrier finishing material in the dry method using the anchor anchoring method, as shown in Figures 1 and 2 usually have a plurality of regular intervals on the outer wall of the building slab. They are arranged side by side and finished to form an exterior wall in the form of a curtain wall.

In the case of constructing such a stone panel 10 by finishing the exterior wall of the building, the truss 20 is usually constructed by using a plurality of fasteners such as the anchor 41 and the bracket 42 and the bolt 43. The truss 20 is fixed to the slab 30, wherein the truss 20 is made of a steel frame such that the vertical member 21 and the horizontal member 22 made of each pipe form a grid-shaped unit module of a certain standard.

Construction of the outer wall in the form of curtain wall by fastening a plurality of fastening members 51 to 53 such as “b” type anchors or brackets and bolts and nuts so that the stone panel 30 is fixed to the truss 20 as described above. Done.

On the other hand, the construction structure of the conventional building exterior stone panel as described above is mainly constructed by a closed joint (open joint) method or an open joint (open joint) method.

That is, the closed joint method is a caulking material (C) made of petroleum compounds in the form of dough, for example, silicon in order to block the inflow of rainwater through a gap of a predetermined interval formed between the adjacent stone panel 10, respectively (C) ) To have a sealed construction structure.

In addition, the open joint method has a construction structure in which gaps of predetermined intervals formed between the stone panels 10 adjacent to each other are opened.

However, in the case of the closed joint construction structure, as the caulking material (C) is exposed to the external environment such as solar heat, ultraviolet light, acid rain, etc. for a long time, the physical property is changed into an oil component, such as an oil band on the outer wall surface of the stone panel 10. As the pollution state such as stains are caused, durability and safety are weakened due to deterioration of the appearance of the building and corrosion of the steel fixtures and trusses 20 such as anchors and brackets due to contamination.

In addition, in the case of the open joint construction structure, condensation occurs due to leakage of rain water through the gap of the stone panel 10, and durability and safety are weakened due to corrosion of steel fixtures and trusses 20 such as anchors and brackets. I have a problem.

On the other hand, according to the construction structure and construction method of the conventional building exterior stone panel as described above, the preparation procedure according to the production, transportation and installation process of the truss 20 is complicated and at the same time anchors or brackets, bolts and nuts, etc. Since the same number of fastening members are required, there is a problem that the construction efficiency is lowered, such as an increase in construction time and construction cost.

Therefore, in Korean Patent Laid-Open Publication No. 2007-117790, a steel truss supporting method for solving the above problems is provided, in which a plurality of unit stone panels have the same planar state while maintaining a constant gap with each adjacent unit stone panel. To be installed in the building slabs arranged side by side to form a curtain wall-shaped exterior wall,

A pair of bracket frames arranged side by side to face both edges of the rear surface of a plurality of unit stone panels, a plurality of anchor bolts fastened to couple the stone panels and the bracket frame, and each of the pair of bracket frames It is provided with a plurality of anchor brackets installed, the gap between each unit stone panel is sealed so that the caulking material filled from the rear is interposed, the rear surface of the caulking material and the rear surface of the unit stone panel is arranged on the same plane parallel to each other A stone panel unit which constitutes a unit unit;

A coupling member coupled to the anchor bar installed on the building slab, and an anchor hole formed to align with the anchor bracket of the stone panel unit so as to fasten the fastening member, are installed to stack a heat insulating member on one surface of the truss to form a unit unit. A frame unit;

And a fastening member for coupling the anchor hole and the anchor bracket through the stone panel unit and the truss frame unit to face each other so as to form a set of unit construction units.

A plurality of unit construction units are installed so that the anchor bar installed in the slab of the building and the coupling member of the truss frame unit are coupled to each other, so that a plurality of stone panels form an exterior wall in the form of a curtain wall on the building slab. The construction structure of the stone panel for barrier formation was presented.

That is, the construction structure of the stone panel for building exterior wall is formed in the factory by forming several anchor holes on the back of several stone panels having a thickness of 30 mm or more and installing bolts thereon, The bracket frame made of steel is fixed to the rear side through a bolting method, and a plurality of anchor brackets are installed on the side portion of the bracket frame to form one stone panel unit, and the anchor bracket of the bracket frame of the stone panel unit is made of steel. The truss frame unit formed by welding or bolt in the shape of a square frame is fixed using bolts to complete one stone panel construction unit and transport it to the site to assemble the building slab.

Such a construction structure has a structure in which the caulking material is filled at the rear of the back of the stone panel, compared with the conventional anchor anchoring method, and thus has a closed joint construction structure, but due to the filling depth of the caulking material When viewed from the front of the panel, it can have the appearance effect of the open joint construction structure, so it can take all the advantages of both construction structures, and standardize by establishing mass production system at separate production sites. As the unit stone panel construction unit in the finished state can be mass-produced and transported to the construction site, it can not only improve the ease of construction, reduce the construction period and construction cost, but also improve the construction quality and material loading space of the construction site. Can reduce the preparation time for the exterior finishing of stone panels. It has advantages

However, this configuration has a form in which the bracket frame is fixed to the back of the stone panel by using nuts and bolts, so that a relatively thin stone panel cannot be used, so at least a thickness of 30 mm or more should be used, which wastes a lot of resources. Of course, the stone panel construction unit of the desired area can not be freely manufactured and constructed, there is a restriction to manufacture and install a plurality of stone panel construction unit for a single wall, and also to fix the stone panel as a unit It is necessary to fix another truss frame unit made of steel that is very heavy on its back, including the bracket frame itself. Therefore, the stone panel construction unit itself has a heavy weight, which leads to high transportation costs and very poor construction. Giving a lot of load to the shim There is a problem in that damage to the building structure.

In addition, including the installation of the bracket frame on the stone panel, when fixing the truss frame unit formed in the square frame shape by using welding or bolts and nuts to the stone panel unit and to fix the stone panel construction unit to the building When using many bolts, nuts, and fastening members, additional materials and labor costs including raw material reel are increased, and the production time of the product is long, resulting in high production cost of the product. There is a problem.

The present invention has been devised to solve such a conventional problem, the stone panel which is widely used as interior and exterior materials of the building to be used as thin as 15㎜-12㎜ as well as the area is very wide, but the stone Frame panels are formed on four sides of the panel in series, and the outer frame extruded from aluminum is combined to fix the square frame in a square frame form to integrally connect the unit connection and the fixing bar to form the stone panel construction unit. The connecting parts of the units are interconnected through the square fixing bar, but if necessary, the "T" type unit connecting and fixing bar is installed on the connecting part to interconnect the stone panel construction units and at the same time, the part is fixed to the casting channel installed in the building. The upper and lower parts of the stone panel construction units can be fixed through the “b” shaped fixing bar. It is possible to install the stone panel construction unit for forming the curtain wall (curtain wall) and the exterior wall by fixing it to the casting channel or fastener fixedly installed at the upper and lower parts of the building, thereby reducing the labor and construction costs according to the interior and exterior construction of the building. It can greatly reduce, save resources, lighten the building, prevent damage to the building structure itself, greatly reduce the air of the new building itself, and stone panels in the factory By manufacturing the unit itself, it is possible to prevent dust generation and industrial waste generation in the new construction site, and it is not necessary to install the scaffolding at the time of construction, and also does not need post-work such as welding, etc. The purpose is to provide a building structure for stone panels for interior and exterior of buildings that do not require any post-work.
