Description

Precast trench which is made of polymer-concrete and drainage structure using the same}

The present invention relates to a precast trench using polymer concrete as a main raw material and a floor drainage structure using the same, and using a high strength precast trench when constructing a drainage trench in a basement floor where groundwater or rainwater may enter the building. Polymer concrete that secures construction quality such as saving construction time and manpower as well as protection of floor waterproofing layer by completing drain concrete trench and easily forming drainage trench without installing formwork at the same time. The present invention relates to a precast trench having a main material and a bottom drainage structure using the same.

The basement floor finish is waterproofing the concrete floor and placing the pressed concrete to protect this waterproofing layer. Conventionally, in the case of constructing the drainage trench of the basement floor where groundwater or rainwater inflow into the building is concerned, the concrete embodiment of FIG. As shown in Fig. 2, the formwork including the wood, plywood, and trench cover mounting angles was installed on the waterproof layer and concrete was poured to form drainage trenches.

However, the installation of formwork for such a conventional drainage trench is constructed by manual labor, and thus, inaccurate manufacturing and assembling is required according to the workmanship of the field technician. It was difficult, and there were many problems such as deformation in drainage trench shape due to the impact during concrete pouring, which caused trouble in the subsequent process.

In addition, as shown in FIG. 1a, nails were used to fix the formwork, which damages the waterproofing layer, and after pouring concrete, removes the formwork after curing, and again, as shown in FIG. 1b, the waterproofing layer for the bottom portion of the drain trench. Due to the need for repair and plastering process, it was cumbersome and inefficient.

Therefore, in order to solve the problems of the drainage trench of the field construction method, a drainage trench unit having a predetermined length is manufactured as a ready-made product at a factory, not a construction site, and then the drainage trench is constructed by assembling and constructing the construction site. Technology has been developed to make ready-made products molded of synthetic resin or cement concrete.

However, in the case of drainage trenches formed of synthetic resins, due to the difference in thermal expansion coefficient between the drainage frame and the bottom concrete, the shape of the drainage frame is frequently lifted off the floor according to the temperature change. Conventional field-construction drainage trenches are still used. In the case of drainage trenches formed of cement concrete, it is difficult to mass-produce in a short period of time and water tightness is necessary for high strength development due to the characteristics of cement concrete. It has the inherent flaw that it is easy to be lacking, has weak chemical resistance, and has great shrinkage and expansion by wet and dry. Its own load is large and it is difficult to cope with it by forming appropriately at corners or intersections. For intersection There is a disadvantage that it is necessary to separately manufacture and equip accessories such as + ruler fittings according to the site conditions. Also, it is difficult to be applied to the site, and the complicated traditional field construction drainage trench as described above is still used. .

The present invention was devised to solve the above problems, and it is easy to construct a trench for drainage by assembling and constructing a trench member of excellent physical properties with super lightweight and high strength manufactured on the spot without installing a formwork on an adhesive mortar. Provides precast trench and main floor drainage structure using polymer concrete, which is easy to work by removing waterproof layer repair and floor plastering process by eliminating damage to floor waterproofing layer due to the use of concrete formwork and improving construction efficiency such as air and construction manpower. The purpose is to.

In addition, the present invention can easily secure the drainage trench of the desired quality without regard to the skill of the construction manpower and the formwork system itself, and the construction quality is improved because there is no deformation of the trench even when the floorless concrete is poured. It is easy to cut with a saw, and precast trenches are mainly made of polymer concrete, which is easy to process, assemble and install at intersections or bends such as L-shaped, T-shaped, and + -shaped according to predetermined site conditions. The purpose is to provide a floor drainage structure.

In addition, the present invention uses a polymer concrete as the main raw material to realize a drainage trench having high durability, fluidity, abrasion resistance, corrosion resistance, chemical resistance, water resistance, etc. suitable for the bottom trench of the building of chemical engineering or emulsified plant field The purpose of the present invention is to provide a precast trench using concrete as a main material and a floor drainage structure using the same.

After the removal, it is possible to prevent the quality damage caused by the construction to provide a perfect quality trench.

Polymer concrete, which is the main raw material of the precast trench of the present invention, is one of the representative construction materials using organic polymer compound (polymer), which is a major commercialization material among organic compounds, and has tensile strength and compression as well as chemical properties such as water resistance and chemical resistance. It is superior to wood or general stone or cement concrete in terms of physical properties such as strength and bending strength, and has been the subject of research for a long time for the manufacture of artificial stone such as tiles, polyester amide and unsaturated polyester. And ethylenically unsaturated resins, polyurethane resins, acrylic resins, and epoxy resins are cured by mixing with a curing agent and aggregate. The curing time is short, and high strength can be expressed early. Flexural and compressive strength Remarkably higher than the material.

In addition, the polymer concrete has a compressive strength of 1,200 to 1,500 kg / cm 2, and as described above, has excellent strength characteristics, resistance to freeze-thawing, water-tightness, water resistance, and various acids, alkalis, salts, etc. Its chemical resistance against various erosive chemicals is also stronger than cement concrete. Abrasion resistance is also very good compared to concrete or wood, making it suitable for flooring and paving. In addition, the addition of a suitable fuel or dye has very excellent properties in adhesion to various building materials such as concrete, stone, metal, wood and glass. Polymer concrete having such a property is being developed for various purposes today, such as a sidewalk block as well as a high performance water and sewage pipe.

Therefore, in the present invention, polymer concrete is used as the main material of the precast trench, and thus the load resistance, processability, light weight, and excellent workability at the time of construction can be secured, as well as chemical resistance and waterproofness.
