Benefits of technology

[0047]According to the present invention, the connecting structure can couple the components by means of a new coupling system, but not by means of welding in forming a multi-directional truss structure having a resistance capability to external activation forces. Thus, if the components are made of a steel material, the connecting structure of the present invention can prevent the rigidity of the material from being lowered by the generation of heat during welding, and contrarily, if they are not made of the steel material (for example, if they are made of composite materials), the connecting structure of the present invention can rigidly couple the components. Also, the connecting structure of the present invention can rigidly couple the components as surrounds the components easily, irrespective of the geometrical sectional shapes of the components including the truss members, thereby reducing the working time for forming complicated and various truss structures. Further, the connecting structure of the present invention can check the safety of the coupled portions by naked eyes in a relatively easier manner than welding, thereby improving the reliability of the coupled portions.
[0048]When the truss connecting structure is used as a steel bar net, a deck plate, and an integrated type of wall form, it is capable of having sufficient rigidity, and especially, when it is used as a deck plate, it has a multi-directional truss structure, such that even when it placed on the lower surface of the deck plate is disposed in any direction thereof, the connecting structure can sufficiently support the load applied to the deck plate.

Problems solved by technology

In this case, however, the conventional trusses have some disadvantages that the surrounding portions of the members connected to each other are lowered at their rigidity by the heat generated during welding, thereby making the load-supporting capability thereof undesirably deteriorated.
Additionally, in the conventional trusses it is difficult to check the safety of the welded state by naked eyes, and so as to check the welded state, thus, an additional method should be introduced.
So as to form the conventional trusses, further, since the points at which the components meet one another are one by one welded, there occur some problems that the truss-forming work is complicated and needs a relatively long period of time, many working persons are required, and the working costs are much consumed.
So as to carry out the welding, therefore, many persons for manual-operations are needed, or high expensive automatic welding production equipment is needed.
In case of using the general steel bars, the rigidity of the steel bar is lowered by the heat generated during welding, thereby making the load-supporting capability deteriorated.
To solve the problems, thus, a relatively expensive heat-resistant material should be introduced, which results in the increase of the manufacturing costs of the deck plate.
Further, the conventional trusses are applied to a wall form, and in this case, the components of the truss are connected by means of welding, such that the same problems as mentioned above occur.
Furthermore, in the case where the components of the truss is formed of not steel, but a composite material, they are not basically connected by means of welding.
In this case, they can be connected by means of chemical bonding, but at this time, the connecting relation is not sufficiently strong, such that it is difficult to adopt the welding as the connecting way of the components formed of other materials.
Especially, in case of having one complicate connecting portion at which a plurality of components are all met like a multi-directional solid truss structure, or in the case where the sectional shapes of the components are not simple, it is difficult to carry out the connecting operations of the truss members by means of welding.
Because of the difficulties or incompleteness of the connection operations, it is found that the multi-directional solid truss structure is really weak at the construction sites.
In constructing the steel bar net at a slurry wall technique, for example, the steel bar net can not be basically made by means of welding, and also, it can not be made by means of chemical bonding providing an incomplete connecting relation.
Up to now, however, no practical connecting method is developed such that the modularized construction has been never tried in the industrial field.

Abstract

The present invention relates to a connecting structure including: a node member having an accommodating space formed therein; a lower truss member disposed penetratingly at the lower portion of the node member, the lower truss member being made of a material with tension and compression-resistant rigidity and having a predetermined length; an upper truss member disposed penetratingly at the upper portion of the node member in such a manner as to be spaced apart from the lower truss member, the upper truss member being made of a material with tension and compression-resistant rigidity and having a predetermined length; and a filler adapted to be filled in the node member in such a manner as to be initially injected in a fluid state into the accommodating space of the node member so as to surround the lower truss member and the upper truss member, and then to be hardened as time elapses so as to rigidly couple the lower truss member and the upper truss member therewith.

Description

TECHNICAL FIELD[0001]The present invention relates to a connecting structure, and more particularly, to such a connecting structure having a new connecting system where a solid type of space frame structure is formed as an integral body.[0002]A space frame is a structural system in which linear members are connected to one another for transmitting a force flow to the linear members.[0003]The space frame may have two-dimensional components, but broadly has a flat or curved shape.[0004]Especially, the space frame having the linear members connected at nodes to one another is called a space truss or simply a truss.[0005]In this case, the term ‘truss’ is more widely used than the space frame, and therefore, it should be noted hereinafter that the truss as a part of the space frame has the same meaning as the space frame.[0006]Generally, if the internal structure and shape of the space frame are determined, the connecting way has to be solved finally.[0007]The connecting way is the most ...
