[0029] See also Figure 1-3 The present invention provides an unlockable assembled modular node, including an upper steel structure module 1 and a lower steel structure module 3. The lower steel structure module 3 and the upper steel structure module 1 are connected by a connecting component 2. The connecting component 2 includes a self-locking connecting rod and a fixing plate 4. Two fixing plates 4 are provided and symmetrically arranged in the upper steel structure module 1. The self-locking connecting rod is arranged between the two fixing plates 4.

[0030] One side of the fixing plate 4 is set as a straight plate structure, and the other side of the fixing plate 4 is provided with a groove 402, and a fixing hole 401 is provided at the center of the groove 402. The fixing hole 401 is used to fix the two fixing plates 4 in the upper steel structure module 1 by fixing bolts 5. A protruding block 1 and a protruding block 2 are respectively provided on both sides of the groove 402. The two protruding blocks are adapted to the structure of the plug 7.

[0031] The self-locking connecting rod includes a bottom plate 702 and two plugs 7. The two plugs 7 are fixedly arranged on the bottom plate 702. The bottom plate 702 and the top of the lower steel structure module 3 are fixedly connected by welding. The tops of the two plugs 7 are provided with conical plugs 701. The outer sides of the conical plugs 701 are provided with inclined surfaces. The bottoms of the two plugs 7 are provided with card slots. The structures of the two plugs 7 are compatible with the structure of the fixed plate 4. Two reset springs 8 are arranged between the two plugs 7. The two reset springs 8 are in a compressed state. The two ends of the reset spring 8 are welded to the two plugs 7.

[0032] Two bolt holes 11 are symmetrically provided on both sides of the upper steel structure module 1. The bolt holes 11 are penetrated by fixing bolts 5 and fixed by fixing nuts 6. The fixing nuts 6 are embedded in the fixing holes 401. The fixing nuts 6 are embedded in the fixing holes 401 without affecting the tight connection between the two fixing plates 4 and the two plugs 7.

[0033] The assembly method of the unlockable assembled modular node comprises the following steps:

[0034] Step S1, weld the bottom plate 702 to the top of the lower steel structure module 3, place the two fixing plates 4 inside the upper steel structure module 1, and pass the fixing bolts 5 through the bolt holes 11 and fix them through the fixing nuts 6 in the fixing holes 401.

[0035] Step S2, insert the two plugs 7 of the self-locking connecting rod between the two fixing plates 4, the inclined surface of the plug 7 contacts the two protruding blocks of the fixing plate 4, the two plugs 7 move inwards, and the reset spring 8 is compressed to shrink.

[0036] Step S3, the two plugs 7 are fully inserted between the two fixing plates 4, the return spring 8 in the compressed state rebounds and provides an outward pushing force to the two plugs 7, the conical plug 701 and the raised card block 1 are fitted together, and the card groove and the raised card block 2 are fitted together, so that the two plugs 7 are fully fitted with the two fixing plates 4 respectively, realizing a self-locking connection.

[0037] When disassembly is required, first use a wrench to remove the fixing bolts 5 in the fixing holes 401 on the fixing plate 4, so that the fixing plate 4 and the upper steel structure module 1 lose their fixing constraints, and the self-locking device is unlocked, so that the two modules can be disassembled.

[0038] Therefore, the present invention adopts the above-mentioned unlockable assembled modular node and assembly method, which can achieve self-locking, reduce on-site workload and improve efficiency. When the structure needs to be disassembled, it is only necessary to use a screwdriver to rotate and twist the fixing bolts of the node box. The node box is convenient for the upper rigid structure module to lose constraint. Driven by the insertion rod, the node box as a whole falls off from the upper steel structure module, and can be dismantled and repaired without destroying the original structure, and the disassembled modules can be reused.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
