Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure of a membrane structure to which an air pocket type membrane is applied,

The present invention relates to a membrane structure capable of utilizing space for various purposes. More specifically, the present invention relates to a membrane structure using a frame member and a divided lightweight membrane in the form of an air pocket mounted on the frame, The present invention relates to a membrane structure capable of being installed in a shape and a shape of a frame and improving the connection structure of a frame for constructing the frame, thereby effectively relieving and supporting the pressure or impact acting on the frame structure and the membrane structure.

In general, the term 'membrane structure' refers to a structure that can perform various activities in a membrane structure by fixing a tent or the like by using a framework formed from the ground. It is easy to install and disassemble, It is installed for the purpose of a space for an exhibition hall, a warehouse or an athletic field for athletic activities or a sports facility.

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 a tensional state of the tent is made through the upper and lower lifting grooves of the tension adjusting means is registered,

According to another embodiment, a vertical frame bar is vertically and horizontally fixed from the tip of a vertically erected column as in the Japanese Patent Registration No. 10-1356011, and a tent is fixed on the frame bar. In the central portion of the tent, And an opening and closing port is formed on the upper portion of the ventilation opening by the elevating means so that the ventilation opening is opened only when necessary so that the ventilation can be smoothly performed.

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, It is the accumulation of rainwater and the risk of collapse.

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 is made up of a frame made using various types of frame members and a divided membrane coupled to the divided space formed in the frame, such as the 2013 Patent Application No. 0133012, It is possible to secure the excellent light-curing property as well as the front and rear surfaces including the side surface to be shielded from rain, wind and sunlight, to be installed simply and quickly, and to provide structural stability It is possible to maintain a stable installation state for a long period of time and to maintain a constant air pressure automatically without accumulation of snow or rain or to keep the air pressure constant. Therefore, a membrane structure using a prefabricated frame structure and a split air cushion .

However, the above-mentioned membrane structure is not expected to be damaged due to a considerable load acting on each joint portion and frame connection portion due to the insufficient buffering action of the frame when the ground is unstable or the wind is blown or impact is applied. And the service life of the membrane structure as a whole is shortened.

That is, the electric film structure has a structure in which a main frame, a side frame, an oblique frame, a lower frame, and a support frame are fastened by bolts and nuts using a columnar frame in the form of an H beam from the ground. So that the ends of the respective frames are connected to each other.

In the case of such a composite frame, if the length of each frame is not precisely cut or machined, or if it has a twisted state, accurate and robust assembly can not be achieved at the connection part. In order to compensate and compensate this, There is a dead end to perform.

Particularly, in the case of a columnar frame erected by using an anchor bolt or the like in the ground, a very high load is exerted due to the pressure of wind as well as the load of the entire membrane structure. Since it is necessary to secure the fastening force, it is necessary to use the excessive steel material and the complicated fastening structure unnecessarily since the over design and the high level safety design must be accompanied.

In addition, in the case of the inclined frame disposed between the main frame and the side frame, the divided membrane serves to complete the overall shape of the frame and the divided membrane must be fixed to the space between the frames. In the case of the side frames and the inclined frame, If pressure is applied by the pressure, there will be flow such as widening or narrowing of each other by the pressure, and this flow not only has a deterioration in service life of the membrane but also does not have proper buffering action, It has a closed end where the load acts.

In the case of the lower end of the side frame fixed to the tip end of the columnar frame and the lower end of the inclined frame and both ends of the support frame connecting the lower side of the inclined frame in the transverse direction, It takes a considerable amount of time to install and construct the membrane structure, and since the number of fastening portions is very large and complicated, uniform assembly and construction can not be accomplished, thereby deteriorating the overall construction quality.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above and it is an object of the present invention to improve the connection structure of each frame with respect to a frame structure by a frame assembly and a membrane structure by an air pocket type split membrane,

It is possible to quickly and efficiently connect and assemble each frame, and effectively cushion and mitigate the pressure or impact acting on the frame structure and film structure, thereby minimizing abrasion and breakage of the connection portion of the frame, It is an object of the present invention to provide a frame connection structure of a membrane structure to which an air pocket type membrane is applied so that life can be greatly extended.
