Description
- 1. Field of the Invention
- The present invention relates generally to a support beam structure capable of extending a span and reducing a height of a ceiling structure and an installing method thereof and, more particularly, to a support beam structure capable of extending a span and reducing a height of a ceiling structure and an installing method thereof, which extends the span between pillars of a building to increase the efficiency of utilization of the building, and reduces the height of a ceiling structure of the building to increase the number of stories within the story height allowed by a specific locale, thus achieving a reduction in construction cost of the building and an increase in an available ceiling height of the building for the same number of stories, thereby maximizing space utilization of the building, and which increases an available area in the case of increasing the number of stories of the building, thus leading to an increase in profits in proportion to the increased area, and which allows components of the support beam structure to be manufactured of ready-made products that are easily purchasable, thus achieving a reduction in material cost and construction cost.
- 2. Description of the Related Art
- Generally, with the progress being made in architecture, a structure, such as a house, supported by pillars or walls, and also a variety of supersized buildings having no pillars, for example, a performance facility, a public hall, an automated factory, an unmanned warehouse, a zoo, a botanical garden, an exhibition center, a hangar, a gym, a leisure facility, etc. are being built. Further, such buildings are being required.
- With the appearance of the above-mentioned building, in order to create a better environmental space, research and development has been constantly made in various fields including research into advanced construction methods and technical development in civil engineering and construction and concrete material for the structural foundation.
- A large space having no pillars advantageously maximizing the utilization of space. If pillars exist in a space, the space utilization is limited to the interval between the pillars. Some space around the pillars may be difficult to use.
- However, the whole interior of a building which has a space having no pillars can be used. Further, this space has excellent adaptability to environmental change. When it is required to change facilities in a building because of a future change in the business environment, it is considerably difficult to place partition walls if there are pillars in the space. However, if there are no pillars, the partition wall may be freely placed, and the space may be adaptable to any change of building use.
- Thus, owners of general buildings prefer a long span building that has pillars separated by a long distance. However, the long span building is problematic in that the thickness of a support beam forming a framework of the building increases as the span increases, so that the height of a ceiling structure increases, a story height of the building increases, and thereby the construction cost of the building increases exponentially. Meanwhile, in the case of a region having a height limit that applies to buildings, it is impossible to provide a desired number of stories to the building, so that profitability decreases remarkably, and besides, construction cost of the building undesirably increases.
- As shown in
FIG. 1 , a modern building is constructed so that asupport beam 91 is placed betweensupport pillars 90 standing upright, and aduct 92 andelectric wiring 93 or other equipment pass through a lower end of thesupport beam 91. In the case of requiring a long span, a stronger andhigher support beam 91 is used. Further, an additional space must be provided on a lower surface of thesupport beam 91 to permit the passage of theduct 92 andelectric wiring 93 or other equipment, and aceiling finishing surface 94 must be provided on the lower end of thesupport beam 91. Thus, the ceiling structure of the building requires a large thickness and the story height of the building must be increased. This overlaps with the above-mentioned problem wherein the number of stories of the building is reduced and space utilization is considerably reduced. - Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a support beam structure capable of extending a span and reducing a height of a ceiling structure and an installing method thereof, which can extend a span, namely, a distance between pillars of a building to enhance space utilization, thus improving utilization of the building, and which can reduce a height of a support beam installed between the pillars to reduce construction cost, and which allows a duct or electric wiring to be installed between support beams, thus enabling a ceiling finishing surface to be directly provided on a lower end of the support beam, thereby achieving a reduction in the story height of a building, therefore allowing a building to have a greater number of stories or allowing the height of each story to be increased for the same number of stories, and thereby enabling pleasant use of a building.
- In order to accomplish the above object, the present invention provides a support beam structure capable of extending a span and reducing a height of a ceiling structure, the support beam structure including: an H-beam extending in a longitudinal direction, an inclined extension part fastened to a lower surface or a side surface of the H-beam and inclined in such a way as to flare at an upper end thereof, a reinforcing part for reinforcing the inclined extension part, a deck placed on an upper end of the inclined extension part, and a concrete layer filling the deck placed on the upper end of the inclined extension part.
- The support beam structure capable of extending a span and reducing a height of a ceiling structure and the installing method thereof according to the present invention is advantageous in that it can extend a span, namely, a distance between pillars of a building to enhance space utilization, thus improving utilization of the building, and it can reduce a height of a support beam installed between the pillars to reduce construction cost, and it allows a duct or electric wiring to be installed between support beams, thus enabling a ceiling finishing surface to be directly provided on a lower end of the support beam, thereby achieving a reduction in the story height of a building, therefore allowing a building to have a greater number of stories or allowing the height of each story to be increased for the same number of stories, and thereby enabling pleasant use of a building.

- As shown in
FIGS. 2A to 2D , a support beam structure A capable of extending the span and reducing the height of a ceiling structure according to a first embodiment of the present invention includes an H-beam 1, aninclined extension part 2, areinforcing part 3, adeck 4, and aconcrete layer 5. The H-beam 1 extends in a longitudinal direction, so that a wide surface is disposed thereon. Theinclined extension part 2 is fastened to a lower surface of the H-beam 1 and inclined in such a way as to flare at an upper end thereof. The reinforcingpart 3 functions to reinforce theinclined extension part 2. Thedeck 4 is placed on an upper end of theinclined extension part 2. Theconcrete layer 5 fills thedeck 4 placed on the upper end of theinclined extension part 2. - A duct 6 or a
pipe 7 for electric wiring is installed in a space V outside neighboringinclined surfaces 22 ofinclined extension parts 2, which are adjacent to but spaced apart from each other. Aceiling finishing panel 8 is disposed right under a lowerhorizontal flange 11 of the H-beam 1. As a result, the space V for accommodating a duct 6 orelectric wiring pipe 7 is formed on a side of the H-beam 1, so that the height for the duct 6 or theelectric wiring pipe 7 is reduced, and thereby the height of the ceiling structure can be reduced. - The H-
beam 1 according to the first embodiment of the present invention has a height of about 300 mm when a span is 10 m. As compared with the conventional H-beam 1 having a height of about 650 to 680 mm, the height of the H-beam of this invention can be reduced by almost half. - The reason why the height of the H-
beam 1 of this invention can be considerably reduced is as follows. That is, the support beam structure A of this invention is configured so that it does not use only the H-beam 1, theinclined extension part 2 is fastened to the lower surface of the H-beam 1, the reinforcingpart 3 is coupled to a top of theinclined extension part 2 and a top of the H-beam 1, and theconcrete layer 5 is cured above theinclined extension part 2. Hence, overall strength of the support beam structure A increases. Thereby, even though a span between pillars is increased to 10 m, the height of the H-beam 1 can be considerably reduced. - Since such an H-
beam 1 may be manufactured using a steel-frame beam that is easily purchasable in the market, the H-beam 1 is inexpensive and thus a reduction in material cost is achieved. The H-beam 1 includes avertical web 13 and upper and lowerhorizontal flanges - The reinforcing
part 3 is fastened at opposite ends thereof to the upperhorizontal flange 12 of the H-beam 1 and anupper fastening bracket 23 of theinclined extension part 2, thus preventing theinclined extension part 2 from sagging downwards.

assembly part 231 of theinclined extension part 2 and theassembly part 321 of the reinforcingpart 3 are coupled with each other via a fastening means 9 including a bolt and a nut. - As such, after
inclined extension parts 2 and reinforcingparts 3 are coupled to opposite sides of the H-beam 1 via the assembly parts, thedeck 4 is disposed on theupper fastening bracket 23 of theinclined extension part 2. Thereby, after thedeck 4 of a wide area is stably installed, a welding process can be comfortably performed without the danger of falling. Thus, when a worker comfortably welds contact portions between the lowerhorizontal flange 11 of the H-beam 1 and alower fastening bracket 21 of theinclined extension part 2 to form a weldedportion 10, the installation of the assemblable support beam structure A has been completed. That is, if anon-welded portion 10 b is formed in the middle of the contact portions between the lowerhorizontal flange 11 of the H-beam 1 and thelower fastening bracket 21 of theinclined extension part 2 without completely welding the contact portions, water can be easily discharged through thenon-welded portion 10 b during concrete casing. -
