A pipe connecting structure is disclosed. The present invention is equipped with a connecting member where a groove is formed in the upper part, wherein a fastener, passing through a hole formed on an outer face of a pipe member connected to a side of the connecting member, is combined with the groove. According to the present invention, provided is a pipe connecting structure capable of securing durability of tensile force applied on a binding part of the pipe member.

Description

Pipe Joint Structure [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe connection structure, and more particularly, to a pipe connection structure that enables durability against a tensile force applied to a joint portion of a pipe member.

In a frame structure such as a disposable booth used in an exhibition hall or the like, or in the construction of various steel structures, an operator is required to couple a plurality of pipe members according to a desired shape.

In the meantime, in the conventional technique, the welding method of metal is widely used when the pipe members are coupled and installed. However, such conventional welding is not only susceptible to fatigue fracture on the welding part, When the tensile force is applied to the welded portion, the jointed state is easily broken.

Accordingly, it is an object of the present invention to provide a pipe connecting structure which makes it possible to ensure durability against tensile force applied to a joint portion of a pipe member.

The pipe connecting structure according to the present invention includes a connecting member 100 having a groove 110 formed on an upper surface thereof and is connected to the groove 110 at a side of the connecting member 100 And a fastener 300 passing through the hole 215 provided on the outer surface of the pipe member 210 is coupled.

Preferably, the grooves 110 are formed in the lateral direction of the connecting member 100.

Further, the bottom surface 115 of the groove 110 forms an inclined surface.

In addition, the bottom of the groove 110 is formed so as to be deeper as it goes in the direction opposite to the side direction of the connecting member 100.

In addition, the depth of insertion of the fastener 300 in the groove 110 is adjustable when the groove 110 and the fastener 300 are coupled.

According to the present invention, there is provided a pipe connection structure which makes it possible to ensure durability against a tensile force applied to a joint portion of a pipe member.

1 is a view illustrating a structure of a connecting member constituting a pipe connecting structure according to an embodiment of the present invention, and FIG.
2 and 3 are views showing a connection structure of a pipe connection structure according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the drawings. It is to be noted that the same elements among the drawings are denoted by the same reference numerals whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a view illustrating a structure of a connection member constituting a pipe connection structure according to an embodiment of the present invention. Referring to FIG. 1, a groove 100 having a rectangular shape is formed on an upper surface of a connecting member 100 forming a pipe connecting structure according to an embodiment of the present invention. At least one groove 130 are formed.

1, the grooves 110 formed on the upper surface of the connecting member 100 are formed in the lateral direction of the connecting member 100. On both sides of the connecting member 100, The first pipe member 210 and the second pipe member 220 are coupled to each other.

The first pipe member 210 has a hole 215 formed on the outer surface thereof for coupling with the connecting member 100. When the first pipe member 210 is coupled to one side of the connecting member 100 The operator joins the holes 215 of the first pipe member 210 and the fasteners 300 such as bolts passing through the grooves 110 of the connecting member 100.

A hole 225 for coupling with the connection member 100 is formed on an outer surface of the second pipe member 220. A second pipe member 220 is coupled to the other surface of the connection member 100 The operator joins the fastener 300 such as a bolt through the hole 225 of the second pipe member 220 and the coupling groove 130 of the coupling member 100. [

The bottom surface 115 of the groove 110 is formed as an inclined surface whose depth gradually becomes shallower as it goes in the lateral direction of the connecting member 100. The worker moves the first pipe member 210, The first pipe member 210 is pulled in the direction opposite to the connecting member 100 as shown in FIG. 2 in order to complete the connection with the connecting member 100.

3, the lower end of the fastener 300 inserted into the groove 110 is caught by the inclined bottom surface 115 of the groove 110, and the lower end of the fastener 300 inserted into the groove 110 by the resistance of the inclined bottom surface 115 Further movement of the five members is blocked.

The lower end of the fastener 300 is hooked on the inclined bottom surface 115 of the groove 110 so that the first pipe member 210 is fixedly installed without being detached from the connecting member 100, 300 and the inclined bottom surface 115, it is possible to resist the tensile force applied to the first pipe member 210.

That is, the first pipe member 210 can secure a high tensile bond strength with the connecting member 100 through the coupling structure as shown in FIG.

In the present invention, the length of the fastener 300 inserted into the groove 110 is preferably shorter than the longest length of the depth of the inclined bottom surface 115 of the groove 110, something to do.

In the present invention, by varying the lengths of the fasteners 300 inserted into the grooves 110, the position at which the fastener 300 is hooked on the inclined bottom surface 115 210 in the horizontal direction).

In addition, in implementing the present invention, by adopting a screw coupling method in coupling the first pipe member 210 of the fastener 300 to the hole 215 and the groove 110, the fastener 300 The operator may adjust the insertion depth of the fastening tool 300 in the groove 110. In this case,

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
