Description

Connection assembly of combined frame

Technical field

The present invention relates to the technical field of space separation in buildings, and more particularly to a docking assembly that can assemble frames of different shapes and sizes. Background technique

In the office areas and exhibitions, various frame-type partitions or partitions are often seen to separate the space. In particular, it is necessary to temporarily arrange a plurality of booths at the exhibition. It is required to be quick and easy to set up on site, and the flexibility of the frame's azimuth change is also relatively high. At present, the technology of constructing such a frame type partition wall generally adopts an aluminum alloy column with a multi-directional groove, which is sandwiched by a plurality of aluminum alloy frames one by one in a groove on the aluminum alloy column, and the frame structure is built. The partition wall plate is set in the aluminum alloy frame to form a frame type partition wall. In this technical solution, the height of the aluminum alloy column is determined, and the height of the partition wall can not be increased, that is, the longitudinal direction cannot be spliced again. The partition wall, and the aluminum alloy frame and the aluminum alloy column are generally fixed by a plurality of screws, and the on-site installation is troublesome, and the aluminum alloy frame needs to bear the weight of the partition wall, and the fixing by the screw is not strong enough.

In view of the above situation, some modular connecting devices for constructing the frame have been invented, which can splicing the partition wall in multiple directions, and the on-site assembly is quick and simple, and the frame structure is relatively firm.

For example, the Chinese utility model patent "A modular frame connecting component" of the patent application number ZL200820087342.1 (publication number CN201206288Y), which I have previously applied for, discloses such a connecting component, which comprises a combined column and a connector for connecting the combined columns, wherein the combined column has a square cross section and has four sides, and a through groove having a certain width is formed on each side along the length direction of the combined column, and the connecting head has six combined columns The outer surface of the connector is connected to the outer surface of the connector by a through pin and a small bolt. The side of the outer surface of the connector has a notch opposite the end of the slot. When the connecting assembly is in use, a plurality of combined columns and connecting heads are connected to each other as needed to connect the required frame, and a partition plate is placed in the space of the frame, and the corners of the partition plate can be hidden in Within the gap, the purpose of separating the space is reached. However, in practical application, considering the needs of the group construction type, the composite column needs to select various shapes of profiles, for example, a cylindrical composite column, a square column-shaped composite column, wherein the square column has a belt-passing groove and a non-passing groove. There is also a composite column with a cross-section in cross section, etc., and in the above technical solution, the shape of the end face of the joint must match the profile of the cross-section of the combined column, so that the two can be matched together, so that for each composite column of different shapes, With the connector of the corresponding shape, the adaptability of the connector is not strong, and the connector itself is made of a solid metal material, and the structure is complicated, which makes the manufacturing cost of the product high.
