Description

Roof structure system for improvement quality of roof waterproofing}

The present invention relates to a roof layer structure system for performing roof layer waterproofing, and more particularly, by setting optimized model-specific standards for the entire construction of a roof layer, and securing organic connection structures between the types related to the waterproofing process. The present invention relates to a roof layer structural system that improves the waterproof quality of a roof layer and has good workability and economic efficiency.

In the building, the roof layer is a space exposed to the outside and must have a structure that must cope with various external environments. The roof layer structure may have different floor finishes depending on the application. Since the roof layer including the rooftop is most in contact with external factors, it is a waterproof function to protect against precipitation, a function to reduce the heat load of solar radiation caused by sunlight, and to keep and insulate the internal heat, and snow load The proper waterproofing method and waterproofing material should be selected in consideration of the ability to handle the loading loads on the roof surface due to weathering and weathering loads.

The waterproof quality of the roof layer is not secured only by the waterproof method. The waterproofing method can prolong the waterproof life of the building only when the organic relationship between the floor and the walls, the drainage layer and the finishing layer, is secured.

1 is a detailed cross-sectional view showing a general roof layer structure used in the roof layer construction.

As shown in the figure, the waterproof layer 104 is constructed on the upper portion of the frame bottom surface 102, and the waterproof protective mortar 106 and the pressed concrete layer 108 are sequentially cast on the waterproof layer 102 to form a roof layer. Done. In the case of the pressed concrete layer 108, the expansion joint 110 is formed at predetermined intervals in consideration of the expansion coefficient of the concrete. In addition, after stacking the masonry brick 114 on the parapet 112 of the roof layer, the cement mortar 116 is introduced between the parapet 112 and the masonry brick 114 and finished with water-based paint. The end of the waterproof layer 104 constructed on the parapet 112 is closed by putting the sealant 118.

The roof layer of the above-described structure is constructed based on the detailed cross-sectional view of FIG. 1, and various constructions (waterproof layer coating, waterproof protective mortar and pressing layer construction, parapet construction, cement mortar construction, etc.) are performed together with the construction. . At this time, each type of construction does not have standardized construction standard or even if it has its own construction standard for each type of construction. The absence of construction standards for each type of roof layer is difficult to expect the waterproof quality to maintain long life throughout the roof layer, and also serves as a main cause of the waterproof defect.

The main causes of waterproof faults are explained in terms of the framing, drain, waterproofing, and finishing processes.

First of all, when looking at the frame section, there is no gradient in the bottom surface of the frame, there is no drain position, there is no bottom gradient in the drain direction. This is the reason that water leaked under the waterproof layer is stagnated in some sections when water is leaked under the waterproof layer due to the lack of adhesion between the concrete surface and the waterproof layer. do.

In the case of the framing vertical plane, the parapet bottom criterion for finishing the waterproofing is incorrect. In other words, the waterproofing material is installed on the vertical surface of the parapet, and the gap between the end of the waterproofing material and the parapet is filled with a sealant or the like, and then the cement mortar and the water paint are coated to finish.

In the above-described construction process, although the sealant fixes the end of the waterproofing material, its adhesiveness is inferior, so that time passes between the sealant and the vertical waterproofing material. Accordingly, the vertical surface waterproofing material flows down, and rainwater flows through the surface of the parapet to penetrate into the waterproofing layer, causing a waterproof defect.

Next, look at the drain section.

According to the standard roof layer specification, the drain should be installed at least 30mm lower than the frame bottom surface, and the drain wing overlapping the waterproof layer is to be overlapped at least 70mm. In addition, the pressure plate should be installed so that the waterproof layer does not rise. Despite these provisions, since the drain position is not secured in the roof layer cross-sectional view of FIG. 1, the worker tends to disregard this criterion and install the drain in any position. Due to the carelessness of the drain construction of the worker, the overlapping portion of the waterproof layer and the drain blades is widened, or the waterproof layer around the drain is prone to be lifted up, which in turn leads to waterproofing.

Next, before examining the causes of waterproofing in the waterproofing method, the basic conditions of the waterproofing layer construction is as follows.

First, the roof layer has a very sensitive reaction to the external environment. In particular, the reaction by heat has a profound effect on the waterproof layer. As shown in FIG. 2, since the latent water trapped in the pressing layer boils in the non-exposed waterproof construction, the fatigue of the waterproof layer is increased, and in the case of the exposed waterproofing, the swelling 104a phenomenon and the breaking phenomenon are also shown.

In order to prevent this phenomenon, the waterproof layer at the bottom of the frame should be constructed considering the material and thickness that can withstand pressure resistance, behavior resistance, fatigue resistance, and deformation temperature limit. If there is a pressing layer, 3 layers of 8 layers of asphalt or double waterproofing of coating film and sheet (only for non-exposure), but at least 5t (usually 4.5t for exposure and 6t for non-exposure) Only when the waterproof layer thickness is maintained can the waterproof performance be achieved.

Since the primary purpose of the waterproofing layer at the bottom of the frame is to drain to the drain side, the waterproofing layer should be inserted obliquely into the drain. In addition, because the end of the waterproof layer is processed in the vertical portion and flows down, it must be forcedly fixed by using a tool such as fixed iron.

Careful measures should be taken to prevent intrusion of water from the end of the waterproofing layer. Interviews are to be carried out at corners, except for coating.

The occurrence of waterproofing defects can be prevented only when the construction conditions of the waterproofing layer are satisfied. However, the detailed condition of the roof layer in FIG. 1 does not describe these specification conditions at all, and the construction of the waterproofing construction depends on the experience of the contractor. As it is done, it becomes the main cause of waterproofing.

Finally, in the finishing process section, the pressed concrete must use expansion joints. In this case, when using a saw-cutting (saw-cutting) because the pressing layer is completely separated, the sawing cutter should be excluded.

The push brick should be constructed to be spaced apart from the parapet so that rainwater does not enter the push brick inside the parapet surface. In addition, the drain screen must be exposed on top of the press layer.

On the other hand, although the pressing layer of the roof may be formed of various materials, it is recognized that the pressing layer should be formed by concrete pouring. Due to this recognition, in order to place the pressed concrete on the roof layer, the construction cost was increased by using a separate pumping device to pump concrete from the ground floor to the roof layer.

As described above, in order to maintain the waterproof quality, as described above, the construction conditions of the four elements (frame, drain, waterproofing, finishing process) are indicated in the roof layer cross-sectional detail diagram and practiced as they are. Must be However, in the conventional roof layer cross-sectional detail diagrams, the construction standards of these four elements are not marked, which not only guarantees the long-life waterproof quality, but also weakens the structural stability of the building due to the occurrence of waterproof defects.

In addition, as another factor deteriorating the waterproof quality of the roof layer, it is due to the process of dividing the entire work type in the construction site by treating only the individual work types rather than in an organic relationship.

Therefore, the present invention has been proposed to solve the above problems, by setting the construction conditions for each type (frame, drain, waterproof method, finishing process) according to the roof layer construction to determine the functional elements of the roof layer At the same time, it systematically secures the waterproofing quality of the entire roof layer by eliminating the factors that can cause water-proof defects by organically connecting the types of work required from the frame construction process to the waterproof finish process. The purpose is to provide a secure roof layer structure system.

In order to achieve the above object, the present invention, during the construction of the frame, the first step of building the frame bottom and parapet by setting the formation criteria of the water cutting groove according to the drain position, floor gradient and parapet construction; A second step of performing a plastering on the bottom of the frame; A third step of installing the waterproofing material on the bottom surface of the frame, and raising the waterproofing material by a predetermined height for the parapet and the vertical wall portion; A fourth step of installing a waterproof layer on a vertical surface of the parapet, and fixing an end of the waterproof layer with a fixing iron; A fifth step of installing a waterproof protective material on the waterproof layer; A sixth step of forming a finishing floor on the waterproof protective material; And it provides a roof layer structure system comprising a seventh step of installing a waterproof protective wall into the water cutting groove of the parapet.

In addition, the present invention is the first step in the case where the frame floor and parapets are constructed, the drain position is determined in the frame bottom surface and the wall portion of the roof layer, and the core hole is formed at the drain position to install the drain; A second step of applying a gradient from the frame bottom to the drain so that water can be smoothly drained and performing a mass plastering process; A third step of installing the waterproofing material on the bottom surface of the frame, and raising the waterproofing material by a predetermined height for the parapet and the vertical wall portion; A fourth step of forming a water cutting groove on the upper bottom surface of the parapet; A fifth step of installing a waterproof layer on a vertical surface of the parapet, and fixing an end of the waterproof layer with a fixing iron; A sixth step of installing a waterproof protective material on the waterproof layer; A seventh step of forming a finishing floor on the waterproof protective material; And it provides a roof layer structure system comprising an eighth step of installing a waterproof protective wall into the water cutting groove of the parapet.

As described above, according to the features of the present invention, the following effects are realized.

First, it is possible to establish specific standards for the parts identified as the cause of defects in the existing waterproof construction and to promote the waterproof quality as a whole through the agreement point of the standard for each construction type. In other words, it is possible to improve the waterproof quality by establishing the structural standard of each type connected with waterproof quality by securing the organic relationship between the construction of the wall including the parapet, the drainage port and the finishing layer from the framework floor construction process. .

Second, when water penetrates under the waterproofing layer when the waterproof defect occurs, the concrete structure is expanded and corroded to damage the frame, and thus the durability of the building is lowered. The present invention basically blocks the cause of the waterproof defect. Thus, the structural stability of the roof layer frame can be secured. In addition, while the existing mandatory maintenance period for waterproofing defects is three years, the present invention can ensure a waterproof quality having a long life of more than 10 years, by removing the closing block can be easily search for the cause of the waterproofing defects Very easy to repair

Third, unified roof layer waterproofing by combining organically in conjunction with the waterproofing quality of each construction that performs draft construction, drain location selection and installation of drainage floor, construction of waterproofing layer, formation of water cut groove on parapet, installation of finishing block, etc. By enabling construction, it is possible to prevent waterproofing defects caused by the worker's carelessness.

Fourth, by using a standardized drainage port compatible with the other types of construction for the roof layer construction, it is possible to improve the smoothness of the drainage, and to improve the workability. In addition, since each construction is constructed according to the unified standard, it is possible to reduce unnecessary material waste and labor costs, thereby securing economic feasibility.

Fifth, by selecting a waterproof method having a waterproof performance of more than a certain criterion and applying it to the waterproofing of the roof layer it is possible to maintain a consistent water repellency and to achieve a low change of the excellent waterproof method.

Sixth, it is possible to prevent the lifting and swelling of the waterproof layer by employing a structure to remove the gas pressure generated under the waterproof layer.

Seventh, it is possible to apply both internal and external insulation of the roof layer, and to achieve the same waterproof quality.

Eighth, the finishing surface is composed of a blocked floor plate rather than pressed concrete, allowing a variety of floor finishes to be selected for roof layer applications, whether exposed or unexposed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIG. 3.

The roof layer structure system according to the present invention secures an organic relationship between the wall including the base and the parapet, the drainage port and the waterproof layer, and the finishing layer, which is a waterproof base surface, and sets a systematic standard for each type connected to the waterproof quality. The construction is implemented to improve the waterproof quality.

The roof layer structure system of the present invention is constructed with its own standards for each type of construction when the roof layer is constructed, and is a system for securing an organic relationship with the next type of construction. This means a structure that can secure the overall quality by connecting all parts of the roof layer in an organic way. In the present invention, the roof construction method with the most important waterproof quality during the construction of the roof layer is configured as a system.

Figure 3 is a cross-sectional detail view showing an embodiment configuration of a roof layer structure system according to the present invention.

In the embodiment of the present invention, first, the basic matters of each type according to the construction of the roof layer, that is, the standard specification is determined. At this time, the standards are established in connection with the waterproofing quality of each type of construction carried out during the construction of the roof layer, while securing an organic relationship with respect to the functionalities between each type.

After the specification of the specification as described above, the construction is carried out as shown in the cross-sectional detail of FIG.

That is, as shown in the drawing, first, when the frame is constructed, the water drain grooves according to the drain position, the bottom gradient, and the construction of the parapet are determined to establish the frame floor and the parapet.

The construction process of the frame bottom 10 and the parapet is as follows.

The frame required for the frame is installed, and the drain is installed at the set position of the frame bottom. The mold is installed on the mold, but the mold is provided to allow water to be smoothly drained when the mold is installed. A reinforcing bar is provided in the present mold, and a parapet mold is provided. At this time, a water cutting groove is formed in the parapet mold. Finally, concrete is poured into the bone mold and the parapet mold to construct the frame floor and the parapet.

As shown in FIG. 4, when placing concrete according to the construction of the frame of the roof layer, the sacrifice plaster is performed according to the gradient given from the frame bottom surface 10 toward the drain 20.

Next, the waterproof layer 30 is laid on the bottom surface 10 of the frame, and the surface of the parapet 12 and the vertical wall 12 ′ are raised by raising the waterproof layer 30 by a predetermined height.

5 is a schematic diagram showing the overlapping construction between the bottom drain and the waterproofing layer, and FIG. 6 shows the overlapping construction between the wall drain and the waterproofing layer. 7 is a sectional view showing the installation criteria of the floor drain.

The upper end of the drain 20 is provided with a dish-shaped wing (20a) for coupling with the waterproof layer to be described later, and the strainer 20b is installed on the upper end of the drain.

As shown in the figure, a portion where the bottom drain 20 and the wall drain 20 'and the waterproof layer 30 meet is constructed by overlapping the waterproof layer 30 on the dish-shaped wing 20a by a predetermined interval. do. The overlap length (ℓ) of the waterproof layer 30 is to be approximately 65mm or more, preferably 70mm to prevent the separation between the waterproof layer 30 and the dish-shaped wing (20a).

The upper surface of the parapet 12 has a predetermined slope, through which the rainwater flows downward. The water cutting groove 14 formed on the bottom of the upper jaw of the parapet 12 prevents water flowing from the upper surface of the parapet 12 from riding on the inner wall of the parapet 12.

The waterproof layer 30 is also installed on the inner wall surface of the parapet 12, and the end portion of the waterproof layer 30 is fixed with the fixing iron 32.

In the waterproof layer construction, a triangular plate 16 is applied to the corner where the parapet 12 and the frame bottom surface 10 meet to perform surface grabbing. Therefore, when the water-tight layer 30 is raised from the edge of the frame bottom surface 10 is constructed to be closed by the triangular plate 16.

In the construction step of the waterproof layer 30 is installed on the bottom of the waterproof layer 30 to determine the size of the de-base 40 for discharging the gas pressure for each predetermined position. By installing the de-base 40 to release the latent simmering water from the skeleton bottom surface 10 to the outside to prevent swelling of the waterproof layer to reduce the fatigue of the waterproof layer and prevent breakage.

Figure 8 is a schematic cross-sectional view showing the de-base construction state, which is the main part of the present invention.

The debase is a vent pipe (42) installed at a predetermined height from the skeleton bottom surface (10); And a degassing cap 44 covering the upper portion of the vent pipe 42. Looking at the construction state of the de-base 40 configured as described above, the vent pipe 42 is installed at a predetermined position of the skeleton bottom surface 10, the deaeration sheet 46 is laid on the skeleton bottom surface 10, the The vent pipe 42 is installed upright to a predetermined height. Then, the waterproof layer 30 is constructed on the degassing sheet 46. At this time, the waterproof layer 30 and the degassing sheet 46 is fixed with a nail or the like.

When the waterproof layer pores are completed, a waterproof layer protective material 50 such as a protective mortar is installed thereon, and a finishing bottom layer 60 is formed on the waterproof layer protective material 50. In the embodiment of the present invention, the finishing bottom layer 60 is installed in a block manufactured in the factory as a unit standard is installed on the waterproof layer protective material 50. Therefore, the existing process of placing the pressed concrete on the roof layer by using the pumping equipment is omitted, thereby reducing the cost according to the mobilization of various equipments, and reducing the number of workers and the working time by 50% or more. City park improves economics. In addition, since the block can be rolled out as needed, there is an advantage of easily finding and repairing a defective part of the waterproof layer, and there is another advantage of freely selecting various floor finishes according to the use of the roof layer.

9A to 9C are various views showing the configuration of the finishing block layer, which is the main part of the present invention.

The block as the finishing bottom layer 60 may have the form of a tetrahedron or a hexahedron, and may be made of one material selected from synthetic resin, preconcrete (PC) material, wood, and metal. As an example of the block, as shown in FIG. 9A, the bottom layer 60a forms a tetrahedron with synthetic resin materials such as rubber, chemical sheets, and artificial fibers, and the upper layer 60b includes stone, sand, rubber powder, artificial stone, etc. The tetrahedron can be formed to form a block.

Further, the block is as shown in Fig. 9B as another example. It is composed of preconcrete material, and has a structure in which a support foot 62 is installed on the floor to stably be positioned on the protective mortar layer. As another example, the block may be composed of a hexahedral flooring material as shown in FIG. 9C. When the construction of the finishing bottom layer 60 is completed, the waterproof protective wall 34 is finally installed into the water cutting groove 14 of the parapet 12.

In the waterproof structure of the parapet 12 as described above, even if rain water flows down the upper surface of the parapet, the water flowing into the inner surface of the parapet by the water cutting groove 14 is blocked, so that the water penetrates into the waterproof layer. It is blocked. According to the above-mentioned parapet waterproof structure, installation of the water cutting groove 14 and the waterproof protective wall 34 eliminates the need for a plastering process, thereby making construction easier.

Reference numeral 70 is an insulating layer.

As described above, a series of models according to the waterproofing layer construction may be constructed in connection with the waterproofing quality, thereby ensuring excellent workability, quality, and maintainability, and improving economics with standard construction.

On the other hand, as another embodiment of the present invention, describes the process of the present invention is applied when the skeleton floor and parapets are constructed, the same process as the above-described embodiment will be omitted detailed.

First, the drain position is set at the frame bottom 10 and the wall of the pre-built roof layer, and the drain 20 is installed by forming a core hole at the drain position. Gradients are provided from the frame bottom surface 10 toward the drain 20 so that water can be smoothly drained, and performing a sacrificial plastering. In addition, the water cutting groove is formed on the upper bottom of the parapet. Since the remaining process is the same as the first embodiment of the present invention described above, a detailed description thereof will be omitted.
