Description

Structure clearance, dismantlement and holding method using polystyrene foam and air mat floor post}

The present invention is difficult to enter heavy equipment during the construction of demolishing the old high-rise buildings in the city, or to remove the elevated roads and bridges, and securely supporting the structure in complex site conditions, while supporting self-weight and work loads with equally distributed loads, dismantling and dismantling The present invention relates to a method for dismantling, dismantling, and supporting copper cladding using expanded polystyrene (EPS) blocks and air mats, which are designed to make work very safe and convenient.

In general, when dismantling the deteriorated high-rise buildings in urban centers, they are crushed by using a crusher from the rooftop or by manpower, or when unavoidable, the small crushing equipment is put up on the rooftop, crushed by a breaker or tongs from the upper floor, As a result, there was a problem in that collapse accidents occurred frequently without supporting the weight of self and working load of the building, and when dismantling and dismantling large structures such as overpasses and bridges, it was necessary to support the gait for each cutting part. In addition, the steel pipe boom or the gasket receives concentrated load at the supporting point, so when the eccentricity is applied, the balance is often lost.If the installation of the glove is not easy, two or more large cranes are cut and dismantled when there is a working space. I have a hard time hanging up until the end of work. High-rise buildings and high bridges have many problems in terms of construction costs and safety construction.

When demolishing and dismantling old high-rise buildings, overpasses, and land and water bridges in urban areas, it is impossible to blast in narrow and complex places where heavy equipment is difficult to enter, and it is not possible to support structures, cut them and lift them with cranes, or It is very difficult to dismantle old structures in the city, such as when the height of the structure is too high for crushing by fork-lane, etc.

In fact, during the dismantling work of large department stores, the heavy weight of heavy equipment was put on the upper floor and the load could not be broken, and many workers collapsed at the same time with heavy equipment, resulting in three deaths. I have shown.

The purpose of the present invention is to easily and safely support the weight and work load of the structure by using EPS blocks and air mats which have been proven to withstand loads of 10 ton per square meter when dismantling old buildings and bridges in the city. The present invention provides a method for dismantling, dismantling, and supporting structures using expanded polystyrene and air mats that can safely dismantle and dismantle.

Structure demolition, dismantling and supporting method using expanded polystyrene and air mat copper bar of the present invention to achieve the above object is to load the EPS block to the required height to withstand large loads and air mat copper at the remaining space of the top or bottom It is characterized by demolishing, dismantling and supporting the structure using expanded polystyrene and air mat copper bar which can safely support the structure by inserting the air in close contact.

Hereinafter, described in detail with reference to the accompanying drawings showing a preferred embodiment of the present invention.

The construction method of the present invention is excellent in compression resistance, the structure or the structure such as piers to dismantle, dismantle and support a certain size of expanded polystyrene block (EPS block (100, 100 ')) that can withstand a load of 10 tons per m 2 (1) the inside of the high-strength fabric to load the required quantity at a height that can support it, and to withstand the pressure of 3kg / ㎥ of air pressure in the gap (2) formed between the upper structure (1) Insert the air mat (200) forming the air chamber in the air injecting air through the air inlet (3) to close the bottom surface of the structure (1) while the EPS block (100) (100 ') to the structure (1) Secure the bottom of the unit so it does not move. Then, when the stacking of the EPS blocks 100 and 100 'is completed, the angle 4 is attached to the corner portion, and the circumference is wrapped around the suspenders 5 to firmly fasten as a general fastening fastener 6. The blocks 100 and 100 'are installed more securely without being separated (see FIG. 1).

Here, the air mat copper 200 is installed on the ground first, the air mat copper (200) that does not inject air when loading the EPS blocks 100, 100 'and EPS blocks 100 (100') on top of it. By injecting air into the air mat copper club 200 by loading), a method of supporting the structure 1 is also possible.

In another embodiment, a plurality of hydraulic jacks 300 are installed on the ground and the EPS blocks 100 and 100 ′ are stacked by stacking EPS blocks 100 and 100 ′ in a state where the steel plate 12 is supported on the upper surface thereof. There is also a method to lift the 100 (') to support the structure (1) and to lift the cut structure safely by the operation of the hydraulic jack (300).

The EPS blocks 100 and 100 ′ used in the present invention are foamed polystyrenes prepared to foam in the process of expanding and volatilizing the blowing agent when applying heat (steam) by infiltrating the blowing agent into the polymer of styrene monoma (SM). It is known to form a self-contained bubble structure inside when foaming as a resin, which has a good blocking effect against heat and moisture.

In particular, it is very lightweight and easy to transport by manpower and easy to install, so it can be installed quickly even in narrow places where large machines cannot enter. It has excellent compressive resistance, so that even if it is stacked up, an independent surface is formed. However, the side pressure does not occur with respect to the load of the upper portion and the deformation is extremely small so that it does not affect the structure 1.

As shown in FIG. 2, the air mat copper club 200 of the present invention is a mat 7 having an air chamber formed therein with a high-strength fabric woven to withstand a pressure of 1 to 3 kg / cm 2 or more of high pressure air pressure. The urethane coating layer 8 is formed on the outer surface, and an air inlet 3 for injecting air is provided at one end.

The inside of the mat 7 is connected to the vertical pile 11 between the upper cloth 9 and the lower fabric 10 bonded to it up and down to the size of the mat (7) when injecting air through the air inlet (3) Due to the vertical pile (11) connected between the upper cloth (9) and the lower cloth (10) to be expanded to form an air mat (200) in a horizontal state that is expanded in a plane without bulging in all directions.

Here, the size of the three-dimensional fiber piles connecting the upper fabric 9 and the lower fabric 10 by the vertical pile 11 to the inside of the mat 7 can be laminated in a plurality of layers to form a larger size. .

In general, when the air pressure is applied to the sealed air mat, the air mat is inflated by the air pressure, so that the middle is swollen up like a ball, so that the heavy material cannot be raised or lowered and cannot be supported. Since the vertical pile 11 is integrally connected between the upper and lower cloths 9 and 10 bonded integrally with the seven, expansion of the air is suppressed when the air is injected, and a strong air mat is maintained to maintain the horizontalness. If you pull out, the upper and lower fabrics (9) (10) are naturally folded to maintain a flat state.

When the air mat 200 of the present invention 200 is 3 × 4m in width and height as a result of the experiment was confirmed that it can support and lift up and down the weight up to about 120ton when injecting air pressure of 1kg / ㎠ Due to the Pascal principle that the allowable pressure to lift the weight by the air pressure is proportional to the unit area, the allowable pressure of the copper mat 200 is proportional to the cross sectional area of the basic air mat. do.

In the figure, reference numeral 12 is an iron plate, 13 is a ring, 14 is a wire rope, 15 is a barge, and 16 is an anchor.

When the present invention as described above is described in order based on the embodiment shown in the accompanying drawings as follows.

3 is an exemplary view illustrating a method of dismantling, dismantling and supporting high-rise structures using EPS blocks and air mats. The EPS block 100 (100 ') is used to calculate an upper load for each required space of a building between buildings or floors. ), And install the air mat club (200) at the top and inject air through the air inlet (3) to the air mat club (200). Because the vertical pile (11) is expanded while maintaining the horizontal, the air mat copper club 200 closes the gap (2) formed between the stacked EPS block 100 (100 ') and the building in a tight and horizontal state Since the weight and work load of the building are evenly distributed, the structure (1) is firmly supported so that work can be safely performed. In this state, the structure (1) to be demolished is cut and lifted or lifted from the upper floor.When in the field directly to the shredding site, such as heavy machinery to demolish only part of it it is possible to safely dismantled.

Here, in the state in which the EPS blocks 100, 100 'and the air mat club 200 are loaded at a constant height, the angle 4 is attached to the four corners as shown in FIG. When fastened as a fastener 6, the loaded EPS blocks 100, 100 'is very firmly installed, thereby enabling safer work.

And, when crushing the building directly in the field such as heavy equipment, heavy equipment should be at a height that can be dismantled, so even in this case, as shown in Figure 4, the EPS block 100, 100 'load the required height and the heavy equipment is rotated on the upper surface When constructing heavy equipment scaffold 400 by supporting a separate iron plate 12 so that EPS blocks 100, 100 'are not damaged during construction, and placing heavy equipment on top of it, the heavy equipment is simply located at the height to work easily. Demolition and dismantling can be carried out, and when moving it can be conveniently moved using the ring 13 connected to the iron plate (12).
