Technical Field

[0001] The invention relates to the field of prefabricated buildings, and in particular to a connection node between two modules of a prefabricated building. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Most of the existing node connection methods between modules are fixed by welding or a large number of bolts, which is more cumbersome to operate and does not meet the convenience of prefabricated buildings. In addition, the connection nodes between modules of existing prefabricated buildings have low strength at the connection nodes, which poses certain safety hazards. Summary of the invention

[0018] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0019] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0020] Embodiment 1 like Figure 1 As shown, a connection node between two modules of an assembled building includes a first module frame 1 and a second module frame 2 arranged on one side thereof. The first module frame 1 and the second module frame 2 are provided with multiple grooves and clamping columns for bite connection.

[0021] A vertical rod 101 is arranged on the first module frame 1, a first connecting seat 3 is arranged on one side of the vertical rod 101, a second connecting seat 4 is arranged on the cross bar 102 of the first module frame 1, and a third connecting seat 5 is arranged on the vertical rod 101 of the second module frame 2; a pressure-bearing rod 8 is arranged between the first connecting seat 3 and the second connecting seat 4, and a triangular stable structure is formed by the pressure-bearing rod 8, the cross bar 102 and the vertical rod 101 on the first module frame 1, and a component force in the horizontal direction and the vertical direction is applied to the first connecting seat 3 at the same time. The first module frame 1 and the second module frame 2 are located between the first connecting seat 3 and the third connecting seat 5, providing a component force for fixing the first module frame 1 and the second module frame 2 in the horizontal direction and the vertical direction.

[0022] The first connection seat 3, the second connection seat 4 and the pressure bearing rod 8 are all movably connected. The first connection seat 3 is provided with a hinge support 301, which can also be replaced with other movably connected modes. In this embodiment, a hinge connection is selected. The first connection seat 3, the second connection seat 4 and the third connection seat 5 have the same structure and are all movably connected.

[0023] like Figure 2 , Figure 4 and Figure 5 As shown, first mounting holes 302 are provided at both ends of the hinge support 301. The number of the first mounting holes 302 can be set as required. In this embodiment, four are provided. Second mounting holes 104 are provided on the vertical rods 101 of the first module frame 1 and the second module frame 2. The second mounting holes 104 are through holes. The number of the second mounting holes 104 can be set as required. In this embodiment, four are provided. A first pin 9 is provided in the second mounting hole 104. Threads are provided at both ends of the first pin 9. The first pin 9 passes through the first connecting seat 3, the folding plate 6, the first module frame 1, the second module frame 2, and the second connecting seat 4 in sequence. Nuts 10 are provided at both ends of the first pin 9. The number of the first pin 9 is the same as the number of the first mounting holes 302.

[0024] The fourth mounting hole 103 and the second mounting hole 104 are both reserved holes for convenience of subsequent installation. The position of the fourth mounting hole set at the crossbar is similar to that of the second mounting hole, so it is not drawn.

[0025] like Figure 3 As shown, a folding plate 6 is arranged between the first connecting seat 3 and the vertical rod 101, and a third mounting hole 11 is arranged on the folding plate 6, and the third mounting hole 11 is a through hole.

[0026] like Figure 2 As shown, the first pin shaft 9 can be clamped and squeezed by nuts 10 at both ends to fix the first module frame 1 and the second module frame 2 in the horizontal direction.

[0027] A fourth mounting hole 103 is provided on the cross bar 102 of the first module frame 1 , and the third connecting seat 5 is connected to the cross bar 102 at the fourth mounting hole 103 . The third connecting seat 5 provides a reaction force for the pressure bearing rod 8 .

[0028] A first sleeve 801 is provided on the pressure-bearing rod 8, and a second sleeve 802 and a third sleeve 803 are respectively provided at both ends of the first sleeve 801. A plurality of limiting holes 804 are provided on the first sleeve 801, and the spacing of the limiting holes 804 can be set according to requirements. A plurality of protruding switches 805 are provided on the second sleeve 802 and the third sleeve 803, and the protruding switches 805 (similar to the protruding switches 805 of umbrellas on the market) can adjust the pressure-bearing rod 8 according to the required length of the first module frame 1 and be stuck in the limiting holes 804 at different positions.

[0029] The diameters of the second sleeve 802 and the third sleeve 803 are smaller than the first sleeve 801 , and the second sleeve 802 and the third sleeve 803 can slide inside the first sleeve 801 , thereby achieving the effect of adjusting the length of the pressure rod 8 .

[0030] The folding plate 6 is composed of three plates spliced ​​together, and is provided with a first mounting plate 601. The second mounting plate 602 and the third mounting plate 603 are respectively provided at both ends of the first mounting plate 601. The first mounting plate 601 is rotationally connected with the second mounting plate 602 and the third mounting plate 603, and other rotating structures such as a rotating shaft or hinges can be provided.

[0031] The reasons for setting the folding plate 6 may include two aspects: (1) When repairing the connection node between two modules of an assembled building, it is necessary to remove the pressure rod 8 and the first connecting seat 3. At this time, only the first pin shaft 9 is connected to the first module frame 1 and the second module frame 2. The addition of a folding plate 6 can increase the contact area of ​​the first pin shaft 9 in the lateral direction, thereby preventing the pin shaft from falling, so that the first module frame 1 and the second module frame 2 can be better fixed during maintenance.

[0032] (2) Since the folding plate 6 is a rotationally connected, the folding plate 6 may be slightly deformed during maintenance, so that the first mounting plate 601, the second mounting plate 602 and the third mounting plate 603 are not on the same plane, so that the first pin shaft 9 receives forces in all directions, which plays a role in fixing the first pin shaft 9, thereby preventing the pin shaft from falling, so that the first module frame 1 and the second module frame 2 can be better fixed during maintenance.

[0033] Therefore, the present invention adopts the above-mentioned connection node between the two modules of the prefabricated building, which solves the problem that the modular building cannot be quickly disassembled or the disassembly cost is too high, and the connection strength at the connection node is low. The connection method of the connection node is simple, convenient and fast, and the connection node between the first module frame and the second module frame is more firm and reliable.

[0034] 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.
