Description

Method for executing wall body of building

The present invention relates to a method for constructing a wall of a building, and more specifically, to form an inner layer by spraying a polyurethane foam on the surface of the base plate, and to form an outer layer by spraying cement malta thereon, to a completely sealed wall construction without joints The present invention relates to a wall construction method of a building having excellent fire resistance, heat resistance, heat insulation, sound insulation, and short construction time.

In general, in constructing a wall of a building, formwork panels are continuously assembled on both left and right sides between vertical members vertically installed on the floor so as to constitute both sides of the wall to be constructed, and the hardware such as the interval retaining zone is bound. It is built by installing supporting materials on both surfaces, placing rebar in the formwork, and then pouring kneaded concrete.

However, this general conventional method requires not only skilled labor for the work, but also shortening of air, and perfect insulation at the joints because the temporary materials such as support materials and gap retaining zones have to be dismantled after wall completion. There was a problem that was not made.

Accordingly, in order to construct a heat insulating material to enhance the heat insulating effect on the finished concrete wall surface, it is necessary to install a heat insulating material such as glass fiber or styro product. Such glass fiber is cumbersome in construction and blows off glass powder harmful to human body. It is extremely limited, and the styro product is not only troublesome to be fixed with a separate finishing material after cutting to fit the site, but also because the joints are not insulated, it is difficult to expect a full insulation effect after construction.

Therefore, the present invention has been proposed in order to solve the conventional problems as described above, the object of which is to achieve a perfect heat-insulating effect at the corner, excellent in fire resistance, heat resistance, heat insulation and soundproofing by seamless and completely sealed construction On the other hand, it is intended to provide a construction method of the wall of the building that can be easy to construction, shortening the construction period.

Subsequently, a plurality of such anchor pins 15 are fixed to the surface of the primary polyurethane layer 14a by pressing, and then the polyurethane foam is again applied to the surface of the cured primary polyurethane layer 14a as the spray device. By spraying to form a secondary polyurethane layer 14b having a predetermined thickness of 20 to 200mm, the secondary polyurethane layer 14b formed by the sprayed polyurethane foam is cured after a predetermined time has elapsed. At this time, since it is difficult to measure the thickness of the secondary polybutene layer 14b during spraying, a separate display part may be displayed in the middle of the length of the pin part 15b so that the operator can perform the spraying operation with a certain thickness. good.

In this case, the head portion 15a of the anchor pin 15 fixed to the primary polyurethane layer 14a is secondary to the primary polyurethane layer 14a as shown in FIG. 4 (c). The secondary polyurethane layer 14b is disposed between the polyurethane layers 14b, and most of the pin portions 15b of the anchor pins 15 are partially exposed, including the bent portions 15c formed at their ends. Since it is buried in, the plurality of anchor pins 15 are fixed integrally with the primary and secondary polyurethane layers 14a and 14b which are sprayed and then rapidly expanded and cured.

And, Table 3 below is a comparison of the characteristics of each material employed in the present invention and the prior art.

Item Conventional example 1 (styro product 50t + 0.5t color steel sheet) Conventional Example 2 (Urethane 50t Sandwich Panel) The present invention (urethane spray 50t + cement mortar 20t) Density (g / cm ² ) 0.016 to 0.030 0.030 to 0.070 0.028 to 0.045 Thermal Conductivity (Kcal / mh ℃) 0.030 to 0.0321 0.018 to 0.022 0.016 to 0.020 Moisture Permeability (g / mh mmhg) 0.06 0.02 0.02 Compressive strength (kg / cm ² ) 1 to 2.3 1.5 to 5 1.5 to 5 Construction period / area 6 people × 1 day = 50m ² 3 persons × 1 day = 100m ² 3 persons × 1 day = 250m ²

As shown in Table 3, the thermal conductivity and moisture permeability of the present invention are lower than those of the conventional examples 1 and 2, but the compressive strength is high, so that the thermal insulation performance and durability are excellent. Since the work productivity is high, which can make several times the number of workers with less work force, the construction period and labor cost can be significantly reduced.

In other words, in the past, the construction period is long, and many labor force is input, excessive labor cost is required, and effective manpower management is difficult, and when the construction surface is exposed to direct sunlight for a long time, the joints, layers, and layers of the plate are weakened in the adhesive strength. Due to the delamination caused by the separation, the present invention is composed of a group of three people, so that the personnel management in the field is easy, the manpower operation is free, and the construction period is short, thereby reducing labor costs as well as the whole construction. It can be prevented from being peeled off due to weak adhesion at the joint, and no abnormality occurs even when exposed to ultraviolet rays for a long time or a sudden temperature change in winter or winter.

According to the present invention as described above, since the curing speed of the polyurethane layer is fast, it is possible to give a foamed product thickness such as a flat surface even on the inclined surface, and the construction is faster than other heat insulators, and easy construction on various kinds of base plates with excellent adhesive strength. It is possible to freely adjust the thickness of the polyurethane layer, there is no reduction in thickness or shrinkage after curing.

In addition, since a continuous continuous insulation foam is formed at the corners where the base plate and the ceiling plate meet each other, complete insulation and waterproof are possible, and at the same thickness, the insulation effect is three to five times higher than other insulation materials. In addition, it saves air than exterior wall treatment masonry and block masonry, and the construction is simple, which can reduce the overall construction cost.

And since the inner or outer wall can be finished with cement layer, the inner and outer wall can be finished in various ways (same as general compact), and the fireproof wall is formed to increase the stability against fire, while the inner and outer wall insulation By applying cement mortar method at the time, air and construction cost can be saved more than dry bit method, and the effect of various external wall construction can be obtained.
