TECHNICAL FIELD OF THE INVENTION
The present invention mainly relates to the structure of beams and their joint structures, and the related structures and related structures of wall materials, floor materials, etc., in the assembly of temporary assembled buildings, fittings, structures, furniture, furniture, and fixtures. It is about.
[0002]
[Prior art]
The inventor has previously been involved in the development of a similar case.
In summary, as shown in FIG. 17, the main material is composed of two elongated members (100) and (100), and both (200) and (200). It consists of a scraping portion (301) on the upper side of both sides and a round hole (302) directly below, while the joint beam has two through holes (101) and (102) at both ends of two elongated members, respectively. First, a bolt (401) is passed through the upper through hole (101) of the two elongated members, and a nut (500) is attached. An appropriate gap is created, and the bolt portion is connected to the bolt receiving portion (301) of the metal fitting. And temporarily tightened, then insert a second bolt (402) into the circular hole (302) immediately below through the through hole (102) at the bottom of the elongated material, tighten the nut (500), and then tighten the nut sequentially. Met.
However, in practice, subtle horizontal and vertical distortions occur between the columns and beams, or between the beams, and as the man-hours increase, the accumulation of the distortions increases the round holes (302) in the lower joint hardware and the corresponding elongated materials. Affects the through hole (102), a step is generated between them, and the second bolt (402) does not pass or does not go smoothly.
Furthermore, since the load is directly applied to the screw portion (403) of the bolt, the re-screwing operation such as unscrewing due to frictional friction is not smooth.
In addition, defects such as buckling of the open portion (303) of the hardware due to excessive tightening of the bolt and nut were pointed out.
In addition, the protrusion of the hexagon bolt nut narrows the range of application, and the monotonousness of deployment by combining only elongated materials is also considered to be a factor that hinders development.
[0003]
[Problems to be solved by the invention]
In the present invention, in consideration of the environmental problem which is the greatest problem in the 21st century, the conventional idea of disposables has been abolished, and the intent has been to develop a recycling-type system material that makes maximum use of resources. In view of the above, the present invention provides a frame structure which slightly relaxes the requirement for fixing upward movement from the principle of load, adopts the concept of temporary construction, and has a member structure of a joint beam which can be variably adapted to repetitive use with good detachability. Focusing on the joint structure, the motto is rational, reliable, smooth, and comfortable, and in the related structure, the vertical characteristics of walls and partitions, and the horizontal surfaces of floors, shelves, ceilings, and other structural characteristics of the beams The aim was to create a system part that could be applied and used as a living space constituent material in all genres, regardless of the inner or outer shape.

The concept of the present invention is based on the effective use of small cross-section materials generated from thinned wood and the like from the standpoint of protecting environmental resources, and economical general commercial materials that have been developed and mass-produced over many years due to high growth. It is a combination effective use. First, the same rigidity as the medium-section material can be exhibited by integrating the two small-section materials with a reinforcing material at an appropriate pitch, that is, by combining them. In addition, the advantage of the structure by the composite can be utilized in the joint structure and the like. The basic concept of a joint beam and a joint structure using two elongated members is the origin of the idea of the present invention.
[0007]
Now, the present invention provides a wall surface and a vertical surface by replacing one of the combined beams of the two elongated members with a panel, and can have both functions of the beam and the wall surface. Strength and stability are significantly improved, and the range of intended uses and creativity can be expanded by the individual choice of individual parts to be used.
[0008]
Furthermore, the size of the reinforcing material joining material in the gap between the two beams is made shallower than the vertical dimension of the beam to provide a concave convex portion in the gap, and the joint material or joint panel is inserted between these to make vertical joints, walls, etc. The surface is configured, and the degree of freedom such as the purpose of use and design is further expanded. On the other hand, joints and wall surfaces in the gaps of the joint beams are defined by defining the border line in the middle of the joint beams, making it easier to use plate or panel materials in the horizontal plane in the enclosure. That is, a horizontal surface is formed by dropping or fitting a plate material or a panel material at the top end of the joint beam in the enclosure, thereby enabling the construction of floors, shelves, ceilings, assembling furniture, and other horizontal surface materials.
[0009]
In addition, all of these system parts are factory-processed according to the module size, and in principle, only assembly work that does not involve any processing work such as cutting, drilling, nailing, etc. on site, and anyone can enjoy it with DIY It is designed to be.
As a result, a system has been realized in which individuals can arrange each system part in a well-balanced manner according to their intended use design, make a desired one with good detachability, and replace it with another one.

【The invention's effect】
First, according to the first aspect of the present invention, the construction of the beam is made of one of the elongated members as a panel, so that the construction accuracy is enhanced, the structure is strengthened, the beam has a wall function, and the intended use is widened. .
In addition, the joining of the joint beams is concentrated at one point in each part, and each part uses a durable female threaded bolt and male screw set, and the joint beam is naturally attached to the center bolt receiving part of the joint hardware together with the joint beam. As a result, man-hour rationalization and temporary work by temporary attachment became possible.
In addition, the one-touch detachable bolt holder has the effect of wedge effect at the same time as the work of fitting the joint metal to the bolt from the inscribed surface of the joint metal, and also has the effect of correcting the verticality and horizontality of beams and columns.
The fixing work after the adjustment is also simple because it is performed by the male screw concentrated at each point, and the screw tightening is smoothly performed because the setting work with the female screw bolt which does not directly apply a load to the screw portion.
In addition, the one-way work using the hanging method and male screws enables near-hand work in places with poor scaffolding, thus preventing danger during construction work and also preventing tampering by returning screws from the outside.
In addition, the use of screw heads that are nearly flat allows safe and secure use for infants and others, and the range of applications has been further expanded.
Disassembly for moving, rearranging, etc. is also smoothly dismantled in reverse order during assembly without damaging the return member by loosening the male screw and tapping upward with a mallet etc. from the lower end of the beam. Is stored or transported compactly without being bulky, and replacement of components is performed in the smallest component unit. By adding and removing components, they can be reused and re-used for new designs and constructions. You can enjoy.
