Description

Composite beam using modular floor boards and columns for coupling

The present invention relates to a composite beam using a modular floor plate and a column for coupling, and more particularly, to providing a modular floor plate forming a floor or ceiling in the process of constructing a building structure, and providing the modular floor plate as a coupling module. It is possible to shorten the time required for construction by combining with a pillar or H-shaped post for coupling using, and in particular, through the coupling module, the modular floor plate and the pillar for coupling or H-shaped post are integrated to improve mutual robustness, It relates to a composite beam using a modular floor plate capable of supporting high load pressure and a column for coupling.

In general, construction of a building structure proceeds in the order of installing columns and then installing girders between the columns, and installing floor plates once the installation of the girders is completed. This took a long time, and there was a problem that the construction cost increased due to this.

In addition, there is a problem in that a large number of workers are required among a plurality of processes, and the quality of the process varies depending on the technical skill level of each worker.

In order to solve the above problems, that is, a technology capable of reducing the time required to construct a building structure and providing the same quality regardless of the skill level of the worker has been proposed. For example, by modularizing some components of the building structure, There is a technology that reduces the amount of work in the field by providing

The modularized partial component is one of pre-fabrication constructions, and the three-dimensional box-shaped module unit fabricated and assembled in a manufacturing plant is transported to a construction site and immediately constructed at a required location. Modular buildings using such a modular construction method are completed by connecting and combining each module unit manufactured in a manufacturing plant in a horizontal or vertical direction at the site.

Here, the characteristic of the modular construction method is that modulars having the same size are mass-produced in a manufacturing plant, transported to the construction site, and transported modulars are placed in the required location and then assembled. It has the advantage of reducing the time required and providing the same quality, so it has recently been widely applied to various types of buildings.

The system constituting the modular building may include a structural system, a floor plate system, a wall system, a ceiling system, a bathroom system, an electrical and facility system, etc. What can be saved is the floor plate system.

An example of the prior art for modularizing the floorboard system is Korean Patent Registration No. 10-1607433. The prior art is a construction method using a modular beam unit, constructing various types of beam units and combining them to form a beam structure. After construction, it is made by installing a deck for slabs between the auxiliary structures.

However, in the construction method of the prior art, since the construction of the reinforcing structure and the installation of the deck for the slab are performed separately, and the unit for the reinforcing structure must be divided into several types and manufactured, the manufacturing cost increases, and the number of units are connected. Therefore, the construction method proposed to reduce the work process rather increased the work process, which made the work cumbersome and had a problem of low reliability of construction quality.

In addition, Korean Patent Registration No. 10-2266630 relates to a method for constructing a building of a composite beam structure using a modular floor plate. Connecting modular floor plates are installed, and a composite beam is constructed by the space formed between adjacent modular floor plates, but the manufacturing cost can be lowered by using only a single unit of the floor plate module, and the composite beam during the installation process of the floor plate module. There is an advantage that the number of work steps can be reduced by allowing the structure to be formed.

However, in the prior art, since the coupling part connected to the floor slab for support and the connection part connecting the upper and lower pillars are separated and constructed separately, the coupling of the floor module is not robust, and as a result, the coupling part is easily separated by load pressure or There was a problem with damage.

In addition, in general, the floor plate is constructed by installing a beam supporting the floor slab and a concrete slab inside it. At this time, the floor plate structure constituting the modular construction is a process of constructing the floor plate structure to secure fire resistance performance. Fire-resistant coatings should be applied to floor beams to ensure fire-resistance.

In the case of floor slabs, in order to minimize noise and vibration problems in building structures, floor beams are generally installed on both sides, then precast concrete (PC) is installed or formwork is installed, reinforcing bars are placed on site, and then concrete is poured. However, since these construction methods and floor plate modules do not significantly reduce the time required for construction, there is a problem in that the economical effect is low, and the fire resistance performance is deteriorated because it is difficult to construct the fire-resistant coating.

The coupling pillar 20 is arranged in the vertical direction and serves as a pillar in the building structure, and the inner steel pipe 21 extending in the vertical direction and the outer steel pipe 22 disposed while surrounding the inner steel pipe 21 ).

The inner steel pipe 21 and the outer steel pipe 22 are each made of a metal material with high rigidity, and as shown in the drawing, they are formed to form a rectangular pillar, but this is one embodiment and according to the shape of the modular bottom plate Form can be changed.

In the present invention, after the coupling pillar 20 is composed of the inner steel pipe 21 and the outer steel pipe 22, combining them increases the bearing capacity against the load pressure and at the same time, at both ends of the inner steel pipe 21 in the longitudinal direction, respectively. It is possible to improve the convenience of finishing work by providing a space in which the coupling module 30 is disposed, but only the external steel pipe 22 is exposed to the outside.

Looking at the construction method of the present invention made as described above, first, a modular floor plate 10 is manufactured in a manufacturing plant and transported to a construction site of a building structure.

At this time, the manufactured modular floor plate 10 may be in a state in which concrete is poured or not poured. Since it is supplied to the site, the construction steps are reduced, which has the advantage of shortening the site construction time, while the weight of each modular floor plate (10) is heavy, so the same number of vehicles that can be transported at a time is used. Even if it is used, only a relatively small number is possible, which increases transportation costs.

On the contrary, when supplying the modular floor plate 10 in which concrete is not poured, the number that can be transported at one time is relatively large, but on-site workability is low because the concrete must be poured and then hardened at the construction site. There is a problem.

It can be reduced, and even in the process of constructing the upper layer upward of the modular floor plate 10, the coupling module 30 fixed to the lower end of the coupling pillar 20 is coupled to the pre-installed modular floor plate 10. By installing the pillars 20 for coupling, construction can be performed while the pillars 20 for coupling are erected vertically, thereby increasing construction convenience and shortening the construction time.
