Description

Curtain wall structure and its construction method using fireproof lightweight inorganic board {Structure for curtain wall and its construction methode}

The present invention relates to a curtain wall (Curtain Wall) structure using a fire-resistant lightweight inorganic board, and more specifically, between the slab of the building and the finishing material in the span section located on the upper and lower slabs in the same line as the slab of the building. By closing the space of fire with fireproof material, it prevents the flame transfer to the upper layer and delays the flame transmission speed in case of fire in the lower floor, and it reduces the life and property damage caused by the fire and cuts off the air movement of each floor to save energy efficiency. It relates to a curtain wall structure using a fire-resistant lightweight inorganic board that can improve the economics by increasing the construction and its construction method.

In general, curtain wall refers to a non-bearing partition wall that does not support a load. Since the wall is made of the same size and relatively light weight, the weight of the building and the load of the foundation frame are reduced and the installation work is performed. Due to this simplicity, it is a trend that is used a lot in high-rise buildings newly constructed.

The installation of the curtain wall has been disclosed in the curtain wall assembly and the curtain wall installation method using the same as 10-2009-0052125.

The previously disclosed patent installs a fastener at a predetermined interval on a building structure, couples a connector to the fastener, and connects a rod to the connector so that a desired assembly is formed, and then the connector is connected and formed in all directions of the assembly. The glass panel was installed in a state where the spacer was coupled to the space part, and the structural sealant was injected between the glass panel and the assembly to fix the glass panel.

However, the previously disclosed patent has the advantage that the assembly structure of the curtain wall is simple and the construction and the view and view of the occupants are secured. However, when a fire occurs in the lower floor with a space formed uniformly between the building structure and the assembly and the glass panel. As a result, flames and toxic gases were rapidly delivered to the upper layer, resulting in increased life and property damage.

In addition, the glass panel and the assembly are damaged by the flame delivered to the space, and there is a problem in that the cumbersome and economic loss to be reconstructed occurs.

In view of the above-described conventional defects as described above, an object of the present invention, the fire-resistant lightweight inorganic board to perform the role of interlayer fire protection by finishing between the frame supporting the finishing material, such as the slab of the building and the laminated glass.

The glass powder, which utilizes the characteristics of the silica sand by powdering glass products generated in daily life, including MgO, Al ₂ O ₃ , K ₂ O but Sio ₂ , CaO, Na ₂ O It is because the acid resistance of the main component is an important role to wrap the foam cell, when the weight is less than 49% by weight, the pore size decreases, the density is increased, and if more than 64% by weight is due to overexposure phenomenon on the surface.

The fly ash is a by-product generated after coal combustion in a coal-fired power plant, and combines with lime in the form of a powder collected in a dust collector to produce a compound having cement properties at room temperature when it meets water. Although, Sio ₂ , Al ₂ o ₃ , Fe ₂ o ₃ is the main component has a strong strength and breathability, excellent bonding strength of heat insulation and cold insulation, and has a semi-permanent characteristics, which is generated during coal combustion 1 to 100um of coal fly ash contained in the exhaust gas and 1 to 40mm bottom ash falling from the furnace wall are included.

Intercrete, which is the surface treating agent, is similar to the component of the glass powder, but contains about 1 to 2 times more of the CaO component than the component of the CaO contained in the glass powder. It is used to improve the smoothness and to smooth the surface.

The water glass (Water Glass) are made by melting the high sand purity of the inorganic is the most widely used of the water-soluble silicate compound in the 1100 ~ 1200 ℃ with _{Na 2 CO 3, K 2 CO} 3, which with the alkali metal SiO ₂ Compounds combined in various molar ratios include sodium silicate, potassium silicate and lithium silicate, which contain about 10-30% of water.

The composition is evenly mixed according to the above composition ratio, the mixed mixture is dried and pulverized, put into a mold to form a fireproof material, and heat treated at 800 to 900 ° C. to form a fireproof material, and the molded fireproof material is cooled to cut to a constant size. Just do it.

The refractory material has a specific gravity of 0.3 ~ 1.6g / cm ³ , bending strength 40 Kgf / cm ² It has a high strength and light weight with a compressive strength of 492 Kgf / cm ² or more, and a thermal conductivity of 0.1 to 0.14 W / mK, which has characteristics of flame retardancy of physical properties and flame retardant grade 1, and has strong characteristics in insulation and flame resistance. The vertical refractory material 141 and the finish refractory material 142 are manufactured by cutting to a certain size according to the design drawing of the structure.

In addition, the present invention is sequentially installed from the lower slab to the upper slab among the slabs of the building in which a plurality of slabs are formed, as shown in FIG. Anchor bolts (130a) is installed to form the installation hole.

After the anchor bolt 130a is installed and fixed to the installation hole, the anchor bolt 131 of the fixing part 130 is seated on the upper surface of the slab 110 to accommodate the anchor bolt 130a. 130a) protrudes into the fixing guide hole (131b) and the fixing body (131a) is seated on the slab 110, fastening the anchor nut (130a ') to the anchor bolt (130a) protruding to the fixing guide hole (131b). To fix the fixed body (131a) to the slab (110).

The anchor bolt 130a is fixed to the slab 110 at the anchor bolt 130a fixed to the edge of the slab 110. The anchor bolt 130a protrudes into the fixing guide hole 132b and has a corner body ( 132a is seated on the slab 110 and the corner nut 132a is fixed to the slab 110 by fastening the anchor nut 130a 'to the anchor bolt 130a protruding from the fixing guide hole 132b.
