Abstract

The present invention relates to an assembly-type structure, which enables a space to be used for various purposes. More specifically, a cross-sectional structure of shaped steel for forming a frame of the structure is improved to have light weight and be able to absorb shocks up to a predetermined level. A porous air panel can be joined and fixated to the shaped steel in an easy manner. The air panel is extrusion-molded to form a separation wall and a space unit therein. A finishing material is formed and joined to an end portion of the air panel. Therefore, the frame and the whole structure can have light weight due to the shaped steel with the improved cross-sectional area structure. The lightweight shaped steel can contribute to convenience of construction and cost reduction and thus is very economic. The air panel can be manufactured to be transparent or to have various colors obtained by double molding or color molding. The air panel not only has excellent productivity but also can be cut to a desired length and a desired size at a construction site and used. Therefore, the air panel has excellent handling properties and convenience of use. The air panel has excellent durability and thus can extend a lifespan for the structure. While resistance by wind is minimized, rain or snow rapidly slips down, and, consequently, can minimize the increase in weight of the structure. Accordingly, structural stability of the structure is excellent. Partial replacement of the air panel is easy since the air panel can be attached to and detached from the frame. Therefore, the assembly-type structure is advantageous in maintenance and management of the structure.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a prefabricated building structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a building-ready structure capable of utilizing space for various purposes, and more particularly, to a built-up structure made of a steel having a light weight and a reinforced section, The air panel can be used to open and install open structures such as arcades, tunnels and dome, or closed structures such as gymnasiums, as well as to provide insulation and performance for all-weather multi-purpose grounds and botanical gardens and soundproof tunnels for sports activities. It is possible to complete the prefabricated structure which is excellent in soundproofness and airtightness, excellent in waterproof effect and dew condensation suppressing effect, can enhance energy efficiency with excellent light fastness, and can maximize the section stress due to the rigidity of the built- And thus can provide excellent structural stability. Structure.

Generally, a building construction structure is made by fixing a synthetic resin sheet, a membrane, a glass or a metal panel to a frame made of various sections, and it can be installed in various sizes and shapes according to the construction site conditions. It is possible to change shape and structure according to the purpose of use such as an arcade, a tunnel or a dome shape.

The most commonly used type of membrane structure is a coated fabric as a main material. In particular, when a flexible membrane is used as a structure to form a roof or a wall, It is a shape resistance type space structure that maintains stable shape against external load by applying initial tension to the membrane. Such a membrane structure can be formed into a free curved shape for a membrane, has a beautiful formative beauty, is excellent in economic efficiency and construction due to light weight of materials, and can be applied to various purposes such as a main stadium of an arena or an arcade in a traditional market Which is gradually expanding to various fields and purposes.

In addition, the above-described film structure can form a bright room by natural light (light transmittance), and is widely used and used for all-weather indoor arenas for daily sports (tennis, gate ball, futsal, badminton, etc.).

Such membrane structures typically consist of support columns mounted upright from the ground and longitudinal and transverse support arms that complete the skeleton of the membrane structure using the support pillars, The membrane structure is completed by forming the ceiling portion through the membrane of the membrane.

In addition, since a wire (steel wire) is embedded at each end of the tent, and a high tensile force is applied to the wire, the tent can always maintain a stable installation state while maintaining a tight tension, The tents of the various types of membrane structures are designed to maintain their original beauty and are designed to prevent fluttering by wind or tent wrinkling.

Particularly, in the conventional membrane structure, a separate tension adjusting means is formed at the tip of a support column installed upright from the inside of the tent as in Patent No. 10-1190055, and the tension adjusting means is connected to the tent and the support column And a suspension membrane structure in which the tensions of the tent membrane can be made through the upper and lower lifting grooves of the tension adjusting means are registered. In addition, as disclosed in Japanese Patent No. 10-1356011, And a tent membrane is fixedly formed on the upper portion of the frame bar. A vent hole is formed in the center of the tent membrane, and a vent opening is formed in the vent hole by an elevating means, An arcade membrane structure has been registered to enable smooth ventilation.

Thus, the existing membrane structure is formed by forming the entire frame through the supporting column made of the steel material and the supporting arm or the frame bar connecting the supporting columns, and then fixing the large tent in a tense state by using the frame In case of the tent film, since the pressure acts in the process of maintaining the tension state, deflection occurs due to the elongation rate when a certain period of time is elapsed. Therefore, the tension adjusting means is necessarily applied together.

However, in the case of the existing membrane structure, since the tension of the tent is constantly or irregularly continuously performed due to the deflection of the tent, it is necessary to continuously perform the tension control operation on the tent, The tension adjusting means and the tent fastening means are easily deteriorated or broken and broken due to the tent air flowing continuously by the wind, so that the lifetime is short.

In addition, since the tent itself is not long in life and is vulnerable due to pollution and external stimuli and impact, it is necessary to replace the tent when using the membrane structure for a long period of time. If the wind blows hard or a lot of rain or snow falls, And there is a risk of collapse as rainwater accumulates. In winter, the difference between the external temperature and the internal temperature is so great that serious condensation occurs and frequent leaks occur at the connection between the roof membrane and the underframe It is true.

Particularly, in the case of a membrane structure using a tent, it is not possible to secure the mining property at all, and since it is very vulnerable to insulation and warming, it has a closed end which should be applied only to simple or temporary facilities. In the case of a conventional membrane structure, Since the side surface of the membrane structure is inevitably opened due to the shape of the membrane structure, the membrane does not have a complete blocking effect from the wind or rain and the shading effect decreases. Therefore, the actual space available for the actual membrane structure is extremely narrow and very unreasonable I have a problem.

Accordingly, the applicant of the present invention has disclosed in Korean Patent No. 10-1599777 that the divided membrane is composed of a frame made of various types of frame members and a divided space formed in the frame, Is formed of air pockets in which air is filled and expanded so as to secure excellent light-curing property, as well as to be able to be shut off from rain, wind and sunlight up to the front and rear including the side surface, can be installed easily and quickly, It is possible to maintain the installation state for a long period of time and to maintain the air pressure automatically without accumulation of snow or rain and to maintain the air pressure automatically so that the membrane structure using the prefabricated frame structure and the split air cushion And registered.

However, since the membrane structure is made of synthetic resin or vinyl, the membrane structure is vulnerable to breakage or damage due to heat or impact. For this reason, frequent replacement occurs. To replace these separate membranes The individual sizes of the divided membranes are so large that they have a problem in that a considerable cost and time and equipment must be input.

In addition, when a load acting on each individual membrane, a rainfall or a rainfall falls, rainwater or snow accumulates on the membrane and the total load increases, so that the frame can not withstand such load, , And thus the maintenance and management costs of such fragile parts are expended enormously.

Furthermore, since the section steel to be applied to the above-mentioned membrane structure must have a rigidity enough to withstand the load of the membrane structure itself and the additional load caused by rainwater, snow or wind, it is a metal pipe of relatively thick thickness. In order to compensate this, the method of increasing the cross-sectional area is applied. However, the existing section steel increases the load due to the increase of the cross-sectional area and increases the load of the entire membrane structure. Since the shock and load can not be buffered, the fracture is still occurring at the connecting portion of each section.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems as described above, and it is an object of the present invention to improve the sectional structure of a section steel for constructing a framework of a structure to realize weight reduction and a predetermined shock absorption, The air panel is extrusion-molded so as to form a partition wall and a space portion therein, and a finishing material is joined to the end of the air panel,

The improved cross-sectional shape of the frame makes it possible not only to lighten the frame structure and the entire structure, but also to contribute to convenience in construction and cost reduction. The air panel has excellent rigidity, excellent mining, insulation and soundproofing, The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a prefabricated structure for constructing a building using an air panel and a reinforced frame capable of restraining waterproofing and condensation phenomenon and allowing construction and installation of various types and sizes of structures.

According to an aspect of the present invention, there is provided a method of manufacturing a steel structure, comprising: a frame formed by organically connecting and fixing a section steel; and a membrane disposed in each of the spaces partitioned between the sections of the frame, In the structure, each of the sections of the frame has an angled recess formed in the horizontal plane on the upper and lower sides, and curved surfaces formed on both sides thereof, the membrane being made of a porous air panel,

And a panel fixing table and a cover fixing table are sequentially disposed on the upper portion of the air panel so that the cover fixing table and the panel And the air panel is pressed and fixed to the section steel by a fastening bolt which is inserted through the press table and is coupled to the panel fixing table.

The present invention is capable of reducing the weight of the frame structure and the whole structure due to the section steel having the improved cross sectional structure and contributing to convenience in construction and cost reduction owing to the lightweight section steel, The air panel which can be manufactured in various colors such as molding is excellent in productivity and can be cut in a required length and shape in the field as well as being excellent in handling property and convenience of use and it is possible to prolong the service life of the structure due to excellent durability This structure minimizes the increase of the load of the structure due to the fact that the rain or the snow slips down rapidly while minimizing the resistance by the wind and thus the structural stability of the structure is excellent. Further improve insulation, airtightness and soundproofing And the excellent adhesion and fixing structure between the frame and the air panel can suppress the excellent waterproof effect and the occurrence of dew condensation. Since the air panel can be easily mounted and separated from the frame, it is easy to replace the air panel part, Which is very advantageous in terms of maintenance and management.
