- With the rapid development of building industry, new construction materials continue to emerge, and light steel keel as a new construction material has been more and more widely used in various building structures because of its excellent properties of light weight, high strength, waterproof, fireproof, earthquake-proof installation and use convenience, and so on. In the course of constructing a structure with light steel keel, different light steel keels generally need to be connected with one another, and what is usually used for the connection is such a manner as welding, bolt connection or riveting.
- Considering the current situation of light steel application, it is necessary that a connecting structure for connection of the light steel keels meet certain requirements: {circle around (1)} requirements on strength, such as, as static strength, a fatigue strength, etc.; {circle around (2)} size requirements, such as, requirements on the center distance between screws, bolts or rivets and the distance from a single center to any side; {circle around (3)} stiffness requirements, for example, requirements on rigidity of the structure which should be strong enough so that a deformation upon resistance to an external load should be small enough not to cause cracking and breakage of a construction material attached thereto, such as a gypsum board; {circle around (4)} process requirements, such as easy and simple processing, reliable operation and stable quality; {circle around (5)} and furthermore, from the perspective of structural design, requirements on material cost advantages such as reduced material weight and lowered material cost, resulted from the design of such a connecting structure.
- By adopting a welding connection, although the above requirements in strength, size and stiffness can be met, this connecting manner is an undetachable connection, such that the recyclability of material is poor, the operation is relatively complex and the pollution to environment is relatively large. Therefore, what is comparatively common is that a detachable connecting manner of bolt connection or riveting is adopted all the same.
- In order to allow the connecting structure of light steel keels, which adopts a detachable connecting manner, to meet the above strength requirements of connection, increasing the diameter of connecting pieces will generally be taken into consideration. However, because the thickness of steel products used for the light steel keels is thin, and the connecting structure has to meet the above size requirements as well, the diameter of the connecting pieces used such as screws, bolts, rivets or the like may not be made too large. Thus, it is impossible that very high requirements on strength are met by the connecting structure with the use of this method.
- And, an existing light steel keel connecting structure that adopts a detachable connecting manner cannot reach very good stiffness requirements, either, and detailed explanation is as follows. A typical structure of light steel wall is shown in
FIG. 1 , in which, a figure on the left side shows the structure of light steel wall in a normal condition where no force acts on it, and a figure on the right side shows the structure of light steel wall after it is deformed by a force. As can he seen fromFIG. 1 , in the event that an existing connecting structure is employed, although there is also a diagonal bracing structure for reinforcing the rigidity of the structure, the structure will be deformed along a diagonal direction in the plane as well, and this kind of deformation will be very obvious upon assembling of the structure. That is, in the figure on the left side, if a fixed constraint is applied to a point B, and a lateral thrust is applied to a point D, then as can be seen from the figure on the right side, deformation of the structure is very obvious in this case. Taking a light steel wall with a size of 2800 (height)×3800 mm (width) as an example, when a load of 40 KG is applied to the point D, the difference in length between diagonal lines AC and BD will reach 60 mm (while the difference between the diagonal lines in case of no deformation is 0), and this deformation tends to bring about damage to the structure itself and to the decoration materials attached to light steel, such as a gypsum board. - Also, because an existing light steel keel connecting structure cannot reach very high strength and stillness requirements, it is usually necessary to increase the arranging density of light steel keels of a light steel assembly so as to ensure stability of the assembly when the connecting structure is in use. In such a way, the above requirements of decreasing, the material weight and reducing the material cost, which needs to be met by the connecting structure, may not be met favorably.
- The main purpose of the invention is to solve such a technical problem suffered by a light steel keel connecting structure in prior art that, strength of connection and rigidity of the structure are not high and the material weight of an assembly that employs the connecting structure is hard to decrease to reduce the material cost.
- For solving the above technical problem, the invention provides a light steel keel connecting structure comprising at least two light steel keels, each of which has a connecting surface connecting with the other light steel keel, and connecting pieces for connecting the light steel keels, characterized in that concaves are provided on each of the connecting surfaces respectively which are depressed toward inside of the light steel keels, and the concaves of two connecting surfaces which are connected vertically are disposed by way of embedding, and at least two connecting holes are provided at corresponding positions of two concaves that are embedded, respectively, and the connecting pieces are provided within the connecting holes in a state of connection.

- In the light steel keel connecting structure, the number of the abutting light steel keel is one, the upper and lower wing plates of the main light steel keel are provided one said concave in symmetric positions of the upper and lower wing plates of the main light steel keel ,respectively, the upper and lower wing plates of the abutting light steel keel are also provided one said concave in symmetric positions of the upper and lower wing plates of the abutting light steel keel, respectively.
- In the light steel keel connecting structure, the number of the abutting light steel keel is two or more, and the upper and lower wing plates of the main light steel keel are provided with concaves arranged in a line in symmetric positions of the upper and lower wing plates of the main light steel keel, respectively, the number of cavities is equal to the number of the abutting light steel keel, and the upper and lower wing plates of each abutting light steel keel is provided with one of said concave in symmetric positions of the upper and lower wing plates of each abutting light steel keel, respectively.
