TECHNICAL FIELD The present invention relates to the field of construction, and more particularly, to a structure for more effectively combining columns and beams of a building.

In order to construct an efficient building, it is necessary to adopt the most appropriate structural form in consideration of various aspects such as the purpose of use, function, safety of external force, and economic feasibility.

The structural form of the building can be divided into wood structure, reinforced concrete structure, steel structure, etc. Today, the reinforced concrete structure and steel structure are the most representative structural forms.

 Reinforced concrete structure is a composite of two kinds of materials, which have excellent compressive strength but weak tensile strength and rebar having the opposite pros and cons. Due to its advantages, it is most actively used from the past to the present.

However, this reinforced concrete structure has a high self weight, is easy to cause cracking, and corrosion of reinforcing bars is a major problem. It has the same disadvantages.

Steel structure is a structural type that assembles steel plate and various shaped steel members by the joining method such as bolting and welding.Its excellent overall structural performance is due to the excellent material itself, and it is organized using heavy equipment such as tower crane. Since the construction time can be shortened and a certain quality can be guaranteed, most large high-rise buildings have recently adopted this structure.

However, this steel structure is also pointed out as a problem that the cost of the material is very expensive compared to other structures, and because the fire resistance is weak, a separate fireproof coating construction is required.

Recently, studies on a so-called hybrid structure system that composes the characteristics of the reinforced concrete structure and the steel structure in a complex manner to complement each other's shortcomings are being actively conducted, and the most representative one is steel reinforced. Concrete) structure.

In constructing the column or beam structure, this structure is designed to reinforce steel bars and cast concrete around the steel member so that these three materials behave as a single body. By contributing the compressive stress) to the concrete, the construction cost can be reduced by reducing the amount of steel frame.

In the case of the above-described steel structure or composite structure, it is very important to combine the steel frame member of the column, the beam forming the skeleton of the structure, the construction and construction method to ensure excellent coupling force while easy construction need.

Conventionally, in joining a beam to a column, a method of using the heavy equipment to position the beam at a certain height and fixing the end of the beam to the column by welding, bolt-nut fasteners, or the like has been adopted. It is inconvenient, and therefore, there is a problem that it is difficult to obtain the structural stability because it is difficult to combine the correct position.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1 below, the coupling structure of the column and beam according to the present invention is basically, a pillar (100); Beam 200 having an upper flange 210, a web 220; An end of the beam 200, the coupling mechanism 300 coupled to the upper flange 210 and the web 220; A catching means 400 for allowing the coupling mechanism 300 to be caught by the pillar 100 and supported upward; In the state that the coupling mechanism 300 is supported by the locking means 400, a fixing means 500 for fixing the coupling mechanism 300 to the pillar 100; is configured to include.

That is, as shown in Figures 1 and 2, the coupling mechanism 300 of a separate structure is mounted to the end of the beam 200, and by the coupling mechanism 300 as shown in Figs. It is to be combined with 100).

In this configuration, both ends of the beams 200 are temporarily supported by the locking means 400 of the coupling mechanism 300 on both sides of the pillars 100, and in this state, the beams 200 are placed in the correct position. Afterwards, the coupling means 300 and the pillar 100 may be combined by the fixing means 500, so that the construction may be convenient, and the construction may be secured by the construction of the correct position. Will be.

The coupling mechanism 300 may be any structure as long as the locking means 400 and the fixing means 500 may be provided, and as shown in FIGS. 1 to 4, the coupling mechanism 300 may be formed in the upper flange 210 and the web 220. The upper and side surfaces of the coupling mechanism 300 are coupled to each other to provide an embodiment in which stable fixing is achieved.

The coupling mechanism 300 may be installed only on one side of the beam 200, but when the beam 200 takes a symmetrical structure around the web 220, the coupling mechanism 300 is also on both sides of the web 220. It is desirable to achieve a symmetrical structure installed in the.

The locking means 400 may be any type as long as the beam 200 has a structure that is temporarily supported by the pillar 100. In FIGS. 1 to 4, a locking groove 410 is formed in the coupling mechanism 300. By taking the structure in which the locking jaw member 420 protrudes outward from the pillar 100, the locking groove 410 of the coupling mechanism 300 is caught and supported by the locking jaw member 420 of the pillar 100. An example is shown.

Here, the locking groove 410 may take any shape as long as it is a structure that is supported by the locking jaw member 420 of the pillar 100, but in the case of taking a structure that is open to the lower side of the coupling mechanism 300, the beam ( In the temporary support structure of the 200, the coupling mechanism 300 can be obtained by the upper side supported by the latching member 420, it can be said to be more preferable in terms of structural stability.

The pillar 100 may be any structure as long as it can combine the beam 200 by the above principle, but in particular, when the steel pillar 100a of the steel structure, it can be seen that the greater utility.

In the case where the pillar 100 has an H-shaped structure which is the most commonly used shape, as shown in FIG. 4, the locking jaw member 420 is supported through both flanges 110 and 120 of the H-shaped pillar 100. By doing so, it is preferable to evenly distribute the load of the coupling mechanism 300 and the beam 200 caught on the end of the locking step member 420.

If the fixing means 500 is a means for fixing the coupling mechanism 300 to the column 100 in a state in which the coupling mechanism 300 is supported by the locking means 400 as described above, a welding method, a bolt-nut Fastening method, rivet method or any other method may be used.

In Figure 4, the coupling mechanism through groove 510 formed in the coupling mechanism 300; A pillar through groove 520 formed in the pillar 100; An embodiment including a fastener 530 such as a bolt and a nut fastened through the coupling mechanism through groove 510 and the pillar through groove 520 is illustrated.

When the coupling mechanism 300 is temporarily supported by the column 100 by the locking means 400, a moment downward occurs about the locking means 400 (the upper side of the locking means 400 is Phenomenon occurs), in order to securely couple the coupling mechanism 300 to the pillar 100 in response thereto, it is preferable that the fixing means 500 is formed above the locking means 400.

Hereinafter, as shown in FIG. 5 or less, the beam 200 extends laterally from the lower end of the web 220, and has a structure having a concrete receiving portion 230 formed with a concrete receiving space therein. An embodiment in the case of taking it will be described.

In this configuration, by fixing the beam 200 to the position where the beam of the building is to be formed, and by simply placing the concrete 20 in the concrete receiving portion 230, the beam structure by the steel plate-concrete composite structure Can be formed.

Furthermore, when the bottom plate support part 231 extends from the outer end of the concrete accommodating part 230 to the inside or the outside thereof, as shown in FIG. 6, a deck plate and a PC (pre-cast) may be used. By pouring the concrete 20 in a state where the bottom plate unit 10 such as slab is supported on the bottom plate support 231, a beam-slab integrated structure can be obtained.

Such a beam 200 can be obtained by processing a steel sheet material by a method such as press working, roll forming, or the like, and may be formed by a folded structure of one steel sheet, or may be formed by a structure combining two or more steel sheets. It may be.

This allows the following effects to be obtained.

First, since the concrete receiving portion 230 of the beam 200 serves to prevent the separation of the poured concrete, no separate formwork installation and dismantling work is required.

Second, the beam 200 basically has a reinforcing effect of the I-shaped steel in the beam structure, and in particular, the bottom plate forming the concrete receiving portion 230 may act as a lower tension member in the steel plate-concrete composite structure. The structurally excellent cross section can be obtained.

Third, when the bottom plate support part 231 is formed at the outer end of the concrete accommodating portion 230, thereby supporting the bottom plate unit 10, when the slab-integral structure is obtained, the slab is not the top of the beam. Since it is located in the dance of the beam, it is possible to reduce the height of the floor as much as the thickness of the bottom plate unit 10, it is possible to further obtain the effect of implementing a slim floor system as a whole.

Here, the concrete receiving portion 230 is preferably formed on both sides of the web 220 to form a symmetrical structure.

Thus, even when the beam 200 has a configuration with the concrete receiving portion 230, as shown in Figure 7, 8 can be employed as the coupling mechanism 300 of the above structure as it is, thereby obtaining The effects are also as described above.

However, as shown in FIG. 8, the concrete receiving portion 230 is preferably formed to be spaced apart from the pillar 100.

When concrete is poured into the steel structure shown in FIG. 8, the structure is as shown in FIG. 9, and the concrete is poured into spaced spaces between the pillar 100 and the concrete accommodating part 230. This is because a beam integrated structure can be formed.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.

The present invention proposes a coupling structure of a column and a beam to facilitate construction, but to obtain excellent structural stability by combining the correct position.
