Description

Technical Field [0001] The present invention relates to a filler-type beam having a slab flange capable of reducing the floor height, and a method of constructing a column bead joint using the same.

The present invention relates to a filler-type beam having a slab flange capable of reducing floor height and a method of constructing a columnar beam connection using the same. More particularly, the present invention relates to a method of constructing a box- It is possible to mount a lightweight floor channel or truss flat deck and expose the upper flange surface of the steel section of the fill beam subjected to bending compression due to bending moment to coincide with the bottom slab, And more particularly, to a method of constructing a joint of a column and a beam using the same.

The self-parking structure of the steel structure has a parking structure and a self-parking lot. A workshop self-parking lot is a steel-framed parking lot with a height of 8 meters or less, which is recognized as a workpiece by the Enforcement Decree of the Building Act, and has no outer wall (hereinafter referred to as "workpiece parking lot").

Unlike parking-dedicated buildings, unlike parking-dedicated buildings, the work permit parking lot is not required for building permits and approval approval procedures, and it is only required to report the construction of the work to the governor of the provincial governor or mayor of the mayor. , Sprinkler, and other fire-fighting facilities are not required, and only the horseshoe or fire-fighting equipment is required. However, the height is limited to 8m or less and the number of floors is limited.

Most of the parking lots in Korea have columns arranged between parking spaces and parking spaces to facilitate the design and construction. In other words, the pillars are placed at 2, 3, 4 times of the minimum width of 2.3m in the parking space in order to build a parking space on the rear side of the parking space with the minimum width of 6m. However, since the designed parking lot of the workpiece has a large number of pillar to be installed, it is difficult to secure the parking space, and there is a problem in the passage and rotation of the vehicle.

In order to solve this problem, a parking lot with a span beam was developed by enlarging the cross section of the beam and eliminating the intermediate column. However, when the long span beam is applied, the dancing of the beam becomes large, so that there is a problem that three layers can not be secured within the height limit of 8m.

On the other hand, in the parking lot law, the minimum ceiling height of parking spaces and parking spaces is defined as 2.3m and 2.1m, respectively. If this height limit applies to a workshop parking lot, a 2.66-meter storey height of 3 m height divided by 8 m height may be granted to secure three floors. Since the maximum height of the beam that can add the economical efficiency of the parking space and the parking space is limited to 50cm when the section of the beam is enlarged and the span of the beam is enlarged to eliminate the intermediate pillar, There was a problem.

As a background of the present invention, there is a Korean Patent Registration No. 0947979 entitled " 3-layer workpiece parking method that can park five vehicles without pole interference "(Patent Document 1). In the background art, "a parking passage of 7 m in width and a parking passage of 4.5 m in the left and right sides of a parking lot structure of a three-story work structure limited to a height of 8 m are secured, (A) a column is placed on the upper part of the foundation, and the column is composed of upper and lower flanges and a web plate perpendicular to the upper and lower flanges, respectively; (B) The height of the column is 8 m, and the anchor bolt and the open part of the steel plate are joined to each other at the positions where the three beams are attached to each other. (C) attaching each layer beam to the column so that the width of the column facing the parking passage is 270 mm in the step (c); (d) a step of fabricating the steel plate by tensioning the central part with a steel wire at a large view center of the middle part of the 16m width, with a view length of 50cm with a length of 12m and a view length of 30cm; (E) When the floor concrete is laid, concrete is put into the column to make filled steel pipe concrete (CFT). The thickness of the concrete is 5 cm in the upper part of the beam, and the thickness of concrete in the upper part of the deck plate is (F) Providing a jack support to the center of the concrete before the concrete is poured, placing the inner beam at a height of 12 m, and securing the structure itself A three-story workshop parking method capable of parking five spaces without pillar interference "is proposed.

However, the background art has a problem in that the cross-sectional shape is complicated, the manufacturing cost is high, the construction is difficult, and the height of the beam is adjusted over the entire beam length.
