Beam, martial arts structure, martial arts parking structure and method for manufacturing a beam, and martial arts structure manufacturing method {BEAM, STRUCTURE, PARKING STRUCTURE HAVING THE BEAM, METHOD OF MANUFACTURING THE BEAM AND METHOD OF MANUFACTURING STRUCTURE WITHOUT COLUMN}

The present invention relates to a beam, a muju structure including the same, a muju parking structure and a method of manufacturing the beam and a method of producing a muju structure, more specifically a beam that can remove the pillars in the structure, and can reduce the height of the structure , And a method of manufacturing a muju structure, a muju parking structure and a beam comprising the same and a method of manufacturing a muju structure.

Recently, the number of vehicles has increased rapidly, and the importance of securing a parking space is gradually increasing. In particular, securing parking spaces in various shopping malls such as large discount stores and department stores in the city is a more important task.

In recent years, commonly used parking structures can be divided into mechanical and self-propelled.

The mechanical parking structure includes a transverse transport apparatus, a lift mounted on the transverse transport apparatus, and a pallet for longitudinal transport, and a pallet mounted on the lift and transported with the parking vehicle to enter or leave the vehicle. Such a mechanical parking structure is usually constructed with a height of 8m or more, and the mechanical parking structure, which is constructed with a height of 8m or more, is defined as a building (Article 118, Clause 8, Enforcement Decree of the Building Act), and applied to the application of a building ratio and a floor area ratio. There are many limitations, and building permits must be obtained before construction.

In contrast, the self-propelled parking structure is formed of a first floor, a second floor, a second floor, a third floor, or a third floor, and a fourth floor formed of a pillar and a floor plate, and thus the structure is simple, and a driver can directly enter and exit a vehicle. These self-propelled parking structures are classified as a work piece under the Building Act when they are manufactured and installed less than 8 meters, so that they can be avoided as a building under the Building Act.

Hereinafter, the conventional self-propelled parking structure will be briefly described.

The results of the structural analysis using the bone beam through the simulation will be briefly described. This structural analysis was performed using the MIDAS program.

The span of the member was 16.5m, the spacing between the columns arranged in one row, or the beam spacing was 3.8m, and the material used was SM490 (Fy = 3,300 kgf / cm ² ). In addition, as a base plate, SS400 (Fy = 2,400 kgf / cm ² ) was applied in the range of 4.5t to 6t or concrete slab THK. = 130mm.

The design conditions of the column surface are as follows.

Fy = 3.3 tf / cm ² , Ms = 53tf-m, Ps = 25.5tf, Lx = 700.0m, Ly = 300.0 cm

The structural analysis results of these conditions are shown in Table 1 below.

In the above Table 1, when the bottom plate is a plate, the combined stresses (combination of compressive stress and bending stress) of the upper and lower flanges (first flange) and the lower flange (second flange) in the column surface, the pillar, and the center of the joint are all Acceptable and in the center, it can be seen that the present invention is applicable to (σ _b −σ _c ) / f _t = 0.520 of the upper flange and σ _b / f _b + σ _c / f _c = 0.709 of the lower flange. .

When slabs are used as slabs, the combined stresses (combination of compressive and flexural stresses) of the column face and column, the upper flange (first flange) and the lower flange (second flange) in the center of the seam are all acceptable and For the case of limiting the central beam dance to 300, it is permissible as (σ _b -σ _c ) / f _t = 0.950 of the upper flange and σ _b / f _b + σ _c / f _c = 0.950 of the lower flange, In the case of limiting the center beam to 400, it can be seen that the present invention is applicable to (σ _b -σ _c ) / f _t = 0.900 of the upper flange and σ _b / f _b + σ _c / f _c = 0.903 of the lower flange. Can be.

Moreover, in the case of the plate, when connecting horizontally without raising, the deflection amount of the center portion was calculated to be about 7.2 cm. Therefore, when the lifting amount of the joint portion is 3 cm, the deflection amount of the central portion can be considerably improved to about 4.2 cm.

If the slab is concrete slab and the central part is limited to 300, the deflection of the center part is calculated to be about 13.12 cm. Therefore, when the lifting amount is 8 cm, the deflection amount of the center part can be improved to about 5.12 cm, and the central part is improved. When limiting to 400, since the deflection amount of the center part was calculated to be about 10.22 cm, when the lifting amount is 5 cm, the deflection amount of the center part can be improved to about 5.22 cm.

According to the present invention as described above, the girders (girder), which is the main member in the steel structure using the H-shaped cross-section (Beam) to form a reinforcement member on both cross-sections of high stress of the member to apply a tensile force and In the central part where the stress is small, the size of the member is minimized.

The present invention can reduce the height of the floor by differently applying the member size of the high stressed end and the member size of the low stressed end when applied to the steel frame parking structure, and thus it is possible to make long spaces, so that it can be used without a middle pillar. The parking efficiency is maximized and economical design and construction has the advantage that can be.

The present invention is a reinforcing member on the upper end of the end portion of the high stress in the section of the steel beam structure in which the beam of the H-shaped cross section is formed in the uneven shape and the bending moment occurs in consideration of the characteristics of the H-shaped steel in the minor moment section By arranging and reinforcing to configure the optimal member. Since the stress of the member is small, it is possible to minimize the cross section of the member to form an economical cross section and to reduce the deflection of the beam.

In addition, a casting-free method using a reinforcing material in the same floor height as the method for installing the inner column enables the long span beam, and the economical construction is possible because the cross section of the internal H-beam is reduced. Due to the absence of the inner column, it is possible to increase the convenience of the driver and accidents that may occur in parking, and to design a difference in height of the muju beam, to secure a space for the facilities installed on the muju beam There is an advantage, it has the characteristics suitable for parking lot, such as distribution center, warehouse.
