Description

Unit Module Connector and Steel House Light Gauge Steel Module

The present invention relates to a steel house lightweight section steel module using the same as the unit module connector, to produce a connector that can ensure a sufficient rigidity using a lightweight section steel, and that can be used to set the connection between the beam and the column using a rigid contact It features.

The modular structure is an industrialized construction that completes the structure by transporting and assembling the box-type module unit produced at the factory, and it is easy to expand and transfer, and can satisfy both economical and residential quality according to development and application conditions. Therefore, it is a system building that has been actively applied to schools, huts, studio officetels, dormitories, and the like.

In the production method of the unit module unit constituting the conventional modular structure, all the ceiling, wall, floor panel with the outer frame made of c-beams, C-beams, H-beams, square steel pipes, etc. are all weight panels, by bolts or welding There is a method of joining these members to each other.

However, the weight panel is usually a member having a thickness of 3.2mm or more to be drilled in a separate fastening hole in advance when the bolt is coupled, it was a factor that increases the air and construction costs due to the risk of fire, manpower and time when welding.

Therefore, as an alternative to manufacturing a module unit using a weight panel, a method of manufacturing a module unit using a light weight panel may be considered.

The lightweight panels are less than 3.2mm thick, and the ceiling panels constituting the module unit are mainly made of light steel or rib steel, and constitute the outer frame.

Such a lightweight panel is thin and can be simply fastened by screwing without having to drill a fastening hole for bolting in advance, and thus, there is no need for bolts or welding joints, thereby improving workability.

However, the unit module using such a lightweight panel has a disadvantage that it is almost impossible to form the joint portion of the beam and the column under the rigid contact condition by using the lightweight section steel as the outer frame. This is because the thickness of the light-weighted steel is mostly 1 to 2 mm, so that welding is impossible at the source, and it is difficult to secure sufficient rigidity even when using a gasset plate.

In addition, in order to lift the unit module, in general, the eye bolt is fastened to the upper part of the column, and the sling belt or the bar is connected to the eye bolt and lifted by the crane. In this case, the phenomenon of stress concentration around the column occurs. There is also a problem that such a stress can not be afforded only by lightweight steel.

Secondly, another object of the present invention is to provide a unit module end connection having sufficient rigidity to handle stress generated during lifting or transportation.

Third, another object of the present invention is to provide a new concept unit module connector that can be more conveniently and quickly produce a module.

Technical composition of the present invention created to achieve the above object is as follows.

The present invention relates to a connector used for a unit module, as a square pipe member. A pillar connection bracket 130 arranged to stand in a vertical direction; A 'c' shaped steel member, the first beam connection bracket 110 being welded to a 'c' cross section on one side of the pillar connection bracket 130; And a second beam connecting bracket 120 welded with a 'c' cross section to the other side of the pillar connecting bracket 130 as a 'c' shaped steel member. The bracket 110 and the second beam connection bracket 120 are orthogonal to each other, and each of the pillar connection bracket 130, the first beam connection bracket 110, and the second beam connection bracket 120 are perforated. It is characterized in that a plurality of screw holes 11 are provided.

In addition, the present invention relates to a steel house lightweight section steel module using a unit module connector, the unit module connector 100 having the configuration of claim 3; As a steel member, both ends are inserted into the column connection bracket 130, and then screwed to connect the unit module connector 100, which is disposed on each of the floor and the ceiling in a vertical direction so as to be symmetrical to each other, the column 400 ; A first bottom edge beam for connecting the unit module connector 100, which is disposed on the floor in the front and rear directions so that both ends thereof are respectively inserted into the first beam connecting bracket 110 and then screwed to each other to be symmetrical to each other. 210; A second bottom edge beam for connecting the unit module connector 100, which is disposed at the bottom in both the left and right directions so that both ends thereof are respectively inserted into the second beam connecting bracket 120 and screwed to each other to be symmetrical to each other. 220; As a member of the first member, both end portions are inserted into the first beam connecting brackets 110 and then screwed to each other so as to connect the unit module connector 100 disposed on the ceiling in the front and rear directions so as to be symmetric with each other. 310; And a second ceiling for connecting the unit module connector 100 arranged in the ceiling in both the left and right directions so that both ends thereof are inserted into the second beam connecting bracket 120 and then screwed to each other to be symmetrical to each other. Edge beam 320; characterized in that comprises a.

Technical effects according to the configuration of the present invention are as follows.

First, it is possible to set the connection between beam and column by hard welding only with lightweight section steel.

In other words, in general, it is almost impossible to form the joints with hard welding conditions using only light steel, but most of the light steel has a thickness of only 1 to 2 mm, which makes it impossible to weld at the source. Because it is difficult. On the contrary, the connector of the present invention can connect the beam and the pillar by screwing while securing sufficient rigidity, thereby satisfying the rigid contact condition.

Second, it is possible to provide a unit module end connection with sufficient rigidity to handle the stress generated during the lifting or transportation process.

In other words, in order to lift the unit module, the eye bolt is generally fastened to the upper part of the column, and the sling belt or the bar is connected to the eye bolt and lifted by the crane. In this case, the stress is concentrated around the column. . As such, the concentrated stress cannot be handled by the light-weight steel alone, but it can handle such stress through a connector having sufficient rigidity, so that the lifting or transportation can be performed safely and conveniently.

Third, the module can be manufactured more conveniently and quickly.

In other words, if the connector is equipped with a pre-drilled screw hole, the unit module structure can be completed by simply inserting the light-weighted steel into the connector and then screwing it in, so that the assembly work can be performed quickly and conveniently. Pre-positioned at each corner can be used as a reference point, the error of the beam or column member can be absorbed inside the connector to increase the accuracy of the final module.
