Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roof beam and a column / beam joint structure.
[0002]
[Prior art]
Conventionally, many beams or trusses for fixing and supporting a heat insulating panel or the like are made of wood. A wooden beam is advantageous in terms of design and construction because a screw nail for fixing the panel can be hit at an arbitrary position.
[0003]
In addition, there are basically two types of joint structures of a column and a beam: (1) a beam winning in which a beam is placed on the column and (2) a column winning in which the beam is supported beside the column.
[0004]
[Problems to be solved by the invention]
However, in recent years, wooden and large cross-section beams are expensive and difficult to obtain. Also, the wooden beam is likely to warp and bend.
[0005]
In addition, when the columns and beams are made of wood, as the problem of (1) beam win, the beam formation changes depending on the support interval of the beams, and therefore the position of the upper end of the beam changes. For this reason, the structure of the upper structure and the roof must be changed. Alternatively, it is possible to change the column length according to the beam formation, but the number of parts and types of columns will increase.
As a problem of the above (2) column winning, the load received by the beam is transmitted to the column with a bolt. However, since the column is made of wood, it is weak against a local load, the bolt sinks, and it is difficult to obtain sufficient proof stress.
[0006]
An object of the present invention is to obtain a beam having a large cross section by obtaining a beam in which wood and steel are integrated, and to obtain a roof beam without warping or bending.
[0007]
In addition, the problem of the present invention is to secure high joint strength and rigidity at the column / beam joint by using a joining member in the column / beam joint structure, and to prevent the upper structure and The purpose is to change the design of the roof, or to obtain a pillar / beam joint structure with fewer pillar parts and types.
[0008]
Further, in the above-mentioned column / beam joint structure, two adjacent columns and beams are joined together to obtain a column / beam joint structure capable of ensuring the accuracy of passage between the beams.
[0009]
[Means for Solving the Problems]
The present invention is a roof beam in which a long material for fixing a roof panel is integrated on the upper surface of each of two adjacent pillars on the upper surface of a beam body made of a steel frame, and two adjacent beams in the longitudinal direction. The lower surface of the joining member that is horizontally projected from each end face of the beam is placed, and the joining plate is placed across the two joining members, and the joining bracket that penetrates both the joining member and the joining plate is used. It is a column / beam joint structure characterized in that both are fixed to the upper end of the column.
[0012]
( Function )
According to the present invention, as a roof beam, a long material for fixing a roof panel is integrated on the upper surface of a beam main body made of steel, so that there is less warping and bending than a large wooden cross-section beam, and the cost is low.・ High precision beams can be obtained.
[0013]
According to the present invention, the column / beam joint structure is a structure in which the lower surface of the joint member horizontally projected from the end surface of the beam is placed and fixed on the upper end surface of the column, so that the beam formation changes. If the relative position of the joining member with respect to the upper end of the beam is made constant, the position of the upper end of the beam is also made constant, and the design change of the upper structure and the roof, or the increase in the number and type of the pillars is small.
Further, since the load of the beam is transmitted to the upper end surface of the column through the joining member and is supported by the axial force of the column, sufficient proof stress can be obtained.
[0014]
According to the present invention, the lower surfaces of the joining members that are horizontally projected from the end faces of the two beams adjacent in the longitudinal direction are placed on the upper end surfaces of the two adjacent columns, and the two joining members Since the joining plate is placed over the two and fixed to the upper end of the pillar by the joining metal fitting that penetrates both the joining member and the joining plate, the joining between the pillar and the pillar can be performed simultaneously with the joining between the beams.
Further, as a joining member provided on the upper end surface of each column, for example, a plurality of bolts and the like can be used to ensure the accuracy of passing the beam.
