Description

Frame joint system of prefabricated structure

The present invention relates to a skeletal joint system of a prefabricated structure, and more specifically, it is excellent in on-site construction without welding equipment and skilled workers because it is assembled without welding by connecting the skeletal frame in straight and right angle directions through a joint module and multi-joint as a medium. , In particular, as a non-exposed assembly in which the joint module and multi-joint are embedded inside the frame, the load bearing capacity for the high-load structure is firmly maintained due to the support structure in which the frame frame is interlocked with the joint module and multi-joint. It relates to a frame joint system.

In general, various prefabricated building structures such as container-type warehouses, multi-story buildings, and barns are constructed in a prefabricated manner by connecting and fixing the frames constituting columns and rafters using connecting pieces and bolt nuts, respectively, and then installing various exterior materials on the outer surface. However, since the frame in a conventional prefabricated building structure is connected and fixed with a bracket and a plurality of bolts and nuts, the connection strength of the assembly part is very weak, so the safety of the building structure cannot be guaranteed.

Accordingly, in the registration No. 10-1702221 disclosed in the prior art, in the assembly member for forming a structure by combining the profile member, the assembly member is oriented so as to be able to be coupled in multiple directions up, down, left and right, and the joint and the joint serving as the base A profile fixture that allows the profile member to be fixedly coupled to the body is fixedly coupled to the joint and the profile fixture, and the coupling direction and shape of the assembly member can be configured in various ways according to the shape of the structure, so that the user can assemble it in the desired state. A technology that can easily form an assembly member by making this possible has been previously registered.

However, the prior art is to form a prefabricated structure using a profile fixture fixed to the end of the profile member and a joint connecting the profile fixture to each other, but there are two types of parts for assembling the profile member, namely, a profile fixture and a joint. In addition to the diversification of parts, after installing the profile fixture on the profile member, the adjacent profile member had to be reconnected with a joint. Due to the cumbersome work method, the site was difficult and the assembly was deteriorated.

In addition, since the profile members are connected to each other around the joint, the load of the structure is concentrated on the bolt connecting the profile fixture and the joint, so the durability against the bending load is very weak, so the safety of the building structure cannot be guaranteed.

Accordingly, the present invention was conceived to solve the above problems, and since the joint module and the multi-joint are used as a medium to connect the frame frame in straight and right angle directions for non-weld assembly construction, the on-site construction is excellent without welding equipment and skilled workers, In particular, as the joint module and multi-joint are assembled without exposure to be embedded into the frame, the frame of the prefabricated structure maintains the load bearing capacity of the high-load structure firmly due to the support structure in which the frame frame is interlocked and coupled to the joint module and multi-joint.
