Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an assembly structure of a frame unit which is a structural body of a so-called unit type prefabricated house.

[Prior art]

The frame unit of the unit type prefabricated house is configured by forming a hexahedron using steel columns and beams. That is, in terms of shape, eight beam members are erected on the upper and lower ends of columns that are erected at four corners at required intervals, and a joist and a horizontal member are further provided between the beam members that form the floor surface and the ceiling surface. Are formed in an appropriate number to form a hexahedron. In addition, the beam member and the horizontal member that form the ceiling surface are omitted to form a frame unit with an open upper surface, and the lower floor ceiling surface and the upper floor surface are formed into a substantially hexahedral shape so that they do not overlap as a frame. There are also things. Japanese Examined Patent Publication (Kokoku) No. 60-133778 discloses a method of assembling a hexahedron frame unit whose ceiling surface is also formed of a beam material or the like. This method is carried out in advance by a side member (elevation frame body), a top surface member (ceiling frame body) and a bottom surface member (floor frame body).
The four frame bodies are appropriately assembled and then sequentially joined and assembled at one point on the production line. That is, the upper and lower sides of a pair of support columns are connected by beam members, and side members formed by projecting joint portions (arms) on one side surface of the support columns are made to face each other on the production line as leading and trailing. Then, the top surface member and the bottom surface member preassembled with the beam material and the beam material of the light-weight C-section steel (channel steel) are conveyed and intervened according to the height position of the joint portion of the facing side surface member, The top surface member and the beam member of the bottom member are inserted and joined to the joint portion of one side member (the leading side) at a position where the end portions of the beam members of the bottom member face each other, and then the joint portion of the subsequent side member and the top surface. The other end of the beam member of the member and the bottom member is inserted and joined. According to this means, there is an advantage that the frame unit can be reasonably produced at one point on the production line regardless of its size.

[Problems to be solved by the device]

However, even by the above means, there are still problems to be solved in the assembly, particularly in the assembly of the frame bodies assembled as the surface members, specifically in the actual joining of the beam member and the arm member. is there. That is, the beam material bears various loads as a building, and transmits the load to the pillar through the armor. Therefore, the beam member and the arm member must be joined so as to bear the load and reasonably transmit the load stress. Therefore, in a house with a relatively light load, grooved steel is used for the beam material as described in the above publication, and the arm member is inserted or extrapolated in close contact with the grooved steel. Usually similar channel steels are used, which can be joined together in part. In this case, if the beam member and the arm member are so-called single pieces and are inserted and joined together as a single member, there will be no serious problem, but between the members assembled as the frame body as described above, the frame body It may be difficult to perform smooth and quick joining due to various factors such as an assembly dimensional error, distortion at the frame surface level, and shape distortion of the joining end portion. In such a situation, labor is required to correct the situation and skill may be required for the work. Furthermore, when the ceiling frame body, the floor frame body, and the elevation frame body are joined and assembled by inserting the armature, the assembly dimension between the elevation frame bodies varies depending on the insertion amount. Positioning control must be performed accurately. The present invention has been devised in view of the above-mentioned conventional problems, and an object thereof is to easily and quickly join the beam member and the arm member assembled as a frame body, and An object of the present invention is to provide an assembly structure in which the assembly dimensions between frame bodies can be easily and accurately set.

[Means for solving the problem]

In order to achieve the above object, the present invention is directed to a pair of upright frame bodies in which armpieces are projectingly provided on the upper and lower sides of respective columns, which are one surface of a frame body in which upper and lower sides of opposing columns are connected by beam members. And a pair of flat frame members constructed by laying a cross member or a joist between a pair of beam members of channel steel whose opening side is the opening side, and the pair of elevation frame members are opposed to each other at a required interval. In the frame unit composed of a hexahedron in which the flat frame body is erected and joined between the upper and lower arm brackets to form a ceiling surface and a floor surface, a flat frame body is inserted between the arm brackets from above. A part of the lower surface piece of the beam member of the plane frame body facing the arm fitting so as to be placed and erected is cut out. Joined frame unit It is an assembly structure of.

[Action]

The upright frame body is set facing the production line by an assembly jig or the like according to the set dimensions of the frame unit to be formed. Next, when the horizontal frame bodies forming the ceiling surface and the floor surface are suspended and positioned slightly above the facing vertical frame bodies by, for example, a crane or the like, the beam member ends of the horizontal frame bodies are raised to the vertical frame bodies. Located on the armor of. Since a part of the lower surface piece of the beam member end is cut out, when the horizontal frame body is hung down as it is, the upper surface piece of the beam member end is placed on and engaged with the arm member. Therefore, after this, in addition to the above-mentioned installation and erection part, a bridge plate is bridged between the cutout lower surface piece and the arm member to join the beam member and the arm member by welding etc. Are integrated.
As for the horizontal frame body, the horizontal frame body forming the floor surface may be suspended first, and the welding and joining may be performed in an appropriate order.
