Description

Technical Field

[0001] This invention belongs to the field of modular building technology, and in particular relates to a positioning and connection structure for modular buildings. Background Technology

[0002] Modular construction, also known as prefabricated assembly construction, is an emerging building structure system. Compared with traditional cast-in-place reinforced concrete and masonry buildings, it divides the building into modular units based on function and structure. These modular units are prefabricated in factories and transported to the construction site for assembly.

[0003] In the connection structure of modular buildings, the connection between steel columns is usually achieved by bolt connection with welding assistance. During the hoisting of steel columns, manual positioning of the steel columns is required. The positioning of the upper and lower steel columns is prone to deviation, which is not conducive to the subsequent installation of steel columns. At the same time, the connection operation between steel columns and steel beams is relatively complicated.

[0004] Therefore, a modular building positioning and connection structure is provided to facilitate the positioning of steel columns when connecting them, and also to facilitate the connection of steel columns and steel beams. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a modular building positioning and connection structure that facilitates the positioning and connection of steel columns, as well as the connection between steel columns and steel beams, while ensuring connection strength.

[0006] To achieve the above objectives, the present invention provides a modular building positioning and connection structure, comprising:

The first steel beam and the first connecting end are fixedly connected by a first fixing bolt.

[0012] Furthermore, the positioning plate includes a positioning plate body laid on the end face of the support plate body. The positioning plate body has a positioning end head that corresponds to and matches the support plate body. The reinforcement is fixed on the end face of the positioning end head. A positioning fixing bolt is provided on the positioning end head. The end of the positioning fixing bolt extends into the support end head and is fixedly connected to the support end head.

[0013] Furthermore, a groove is formed on the end face of the support plate away from the first steel column, and the three support ends are recessed through the groove. The positioning plate is laid in the groove, and the end face of the positioning plate away from the first steel column is flush with the end face of the support plate away from the first steel column.

[0014] Furthermore, a limiting post is fixedly attached to the end face of the support end away from the first steel column, and a limiting hole matching the limiting post is opened on the positioning end. The limiting post is located in the limiting hole, and the positioning plate is limited by the limiting post.

[0015] Furthermore, the positioning end includes a plurality of positioning columns fixed on the end face of the positioning plate away from the support plate, and a positioning block is fixedly connected to the inner wall of the bottom of the second steel column. The positioning block has a positioning hole that matches the positioning column, the positioning column extends into the positioning hole, and the bottom end of the second steel column overlaps the positioning plate.

[0016] Furthermore, a base ring is fitted and fixed on the end of the positioning post near the positioning plate, and the base ring is fixedly connected to the positioning plate.

[0017] Furthermore, the second mounting platform includes an upper plate that is sleeved and fixed to the outer wall of the second steel column, the upper plate having an upper end that matches the supporting end;

[0018] The second connecting end has a T-shaped structure. The flat end of the second connecting end is fixedly connected to the end face of the upper end.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-6 The present invention provides a modular building positioning connection structure, comprising: a first steel column 1, a first mounting platform 2 fixedly fitted at the top, a first connecting end 3 respectively provided on the three sides of the first mounting platform 2, and a first steel beam 4 fixed on the first connecting end 3.

[0036] The bottom of the first steel column 1 is fixed in the foundation or connected to another steel column. The bottom structure of the first steel column 1 is the same as the bottom structure of the second steel column 6, so as to realize the connection between the two ends of the steel column. The first mounting platform 2 is used to support the second steel column 6 and install the positioning plate 5. First, the positioning plate 5 used to position the second steel column 6 is installed and fixed on the first mounting platform 2. Then, the second steel column 6 and the second mounting platform 7 on the second steel column 6 are installed on the positioning plate 5, so as to realize the support of the second steel column 6 by the first mounting platform 2.

[0037] The positioning plate 5 is fixed on the top surface of the first mounting platform 2. The end of the positioning plate 5 away from the first mounting platform 2 is fixed with a positioning end. Two reinforcing parts are fixed on the side wall of the positioning plate 5 corresponding to the first connecting end 3. The first connecting end 3 is located between the two reinforcing parts.

[0038] The positioning end is used to position the second steel column 6, and the reinforcing part is used to connect the first steel beam 4 and the second steel beam 9.

[0039] The second steel column 6 is fixed on the top surface of the positioning plate 5, and the positioning end extends into the second steel column 6 to position the second steel column 6. The outer wall of the second steel column 6 is fitted with a second mounting platform 7. The side wall of the second mounting platform 7 corresponding to the first connecting end 3 is provided with a second connecting end 8. The second connecting end 8 is fixed with a second steel beam 9. The reinforcement is fixed with the first steel beam 4 and the second steel beam 9.

[0040] A second mounting platform 7 is fitted onto the bottom of the second steel column 6. After the positioning end positions the second steel column 6, the bottom end of the second mounting platform 7 contacts the positioning plate 5 and the first mounting platform 2, and the second mounting platform 7 is supported.

[0041] Further optimize the plan, referring to Figure 1 , Figure 2 , Figure 3 The first mounting platform 2 includes a fixed sleeve 10 that is sleeved and fixed to the outer wall of the first steel column 1. A support plate 11 is fixed to the end of the fixed sleeve 10. The support plate 11 is disposed on the end face of the first steel column 1. The support plate 11 has support ends 13 protruding in three directions.

[0042] Understandably, the support plate 11 has four side walls, three of which extend to form support ends 13, and the other side wall does not protrude. Therefore, the non-protruding side wall is a flat edge when it is in cooperation with the two support ends 13.

[0043] The first connecting end 3 has a T-shaped structure. The flat end of the first connecting end 3 is fixedly connected to the end face of the support end 13. The end face of the first steel beam 4 near the first connecting end 3 is provided with a first groove 14 that matches the protruding end of the first connecting end 3. The first steel beam 4 and the first connecting end 3 are fixedly connected by the first fixing bolt 15.

[0044] The presence of the support end 13 increases the support area on the one hand, and is used to connect the first connecting end 3 on the other hand. Both the first steel beam 4 and the second steel beam 9 can be I-beams. The first groove 14 opened on the end face of the first steel beam 4 near the first connecting end 3 is used to accommodate the protruding end of the first connecting end 3. The protruding end of the first connecting end 3 is embedded in the first groove 14, and then the first fixing bolt 15 is driven into the outside of the first steel beam 4 to fix the first steel beam 4 and the first connecting end 3.

[0045] Further optimize the plan, referring to Figure 1 , Figure 2 , Figure 4 The positioning plate 5 includes a positioning plate 16 laid on the end face of the support plate 11. The positioning plate 16 has a positioning end 17 that corresponds to and matches the support plate 11. The reinforcement is fixed on the end face of the positioning end 17. A positioning fixing bolt 18 is provided on the positioning end 17. The end of the positioning fixing bolt 18 extends into the support end 13 and is fixedly connected to the support end 13.

[0046] Understandably, the positioning plate 16 has three positioning ends 17 that correspond to and match the support ends 13. The positioning plate 16 is a flat plate structure, which is laid on the surface of the support plate 11 and connected and fixed to the support plate 11 by positioning and fixing bolts 18.

[0047] In a further optimized design, a groove 19 is provided on the end face of the support plate 11 away from the first steel column 1. The three support ends 13 are recessed through the groove 19, and the positioning plate 16 is laid in the groove 19. The end face of the positioning plate 16 away from the first steel column 1 is flush with the end face of the support plate 11 away from the first steel column 1.

[0048] A groove 19 is provided on the support plate 11 to facilitate the positioning of the positioning plate 16 when it is installed.

[0049] Understandably, the presence of the groove 19 causes the three support ends 13 to sink, and the support plate 11 maintains a constant height by protruding the side wall, which facilitates the installation of the positioning plate 16 in the groove 19.

[0050] To further optimize the scheme, a limiting post 20 is fixedly attached to the end face of the support end 13 away from the first steel column 1. A limiting hole 21 matching the limiting post 20 is opened on the positioning end 17. The limiting post 20 is located in the limiting hole 21, and the positioning plate 16 is limited by the limiting post 20.

[0051] When installing the positioning plate 16, align the limiting hole 21 with the limiting post 20. The presence of the limiting post 20 ensures that the positioning plate 16 cannot move relative to the supporting plate 11, thus guaranteeing the secure installation of the positioning plate 16.

[0052] Further optimize the plan, referring to Figure 2 , Figure 4 , Figure 6 The positioning end includes several positioning posts 22 fixed on the end face of the positioning plate 16 away from the support plate 11. The bottom inner wall of the second steel column 6 is fixed with a positioning block 23. The positioning block 23 is provided with a positioning hole 24 that matches the positioning post 22. The positioning post 22 extends into the positioning hole 24. The bottom end of the second steel column 6 overlaps the positioning plate 5.

[0053] Understandably, the positioning column 22 can be a cylindrical structure at the bottom and a pointed structure at the top. When installing the second steel column 6, the second steel column 6 is hoisted and the positioning hole 24 on the positioning block 23 is aligned with the positioning column 22. The positioning column 22 is then inserted into the positioning hole 24 to limit the position of the first steel column 1 and the second steel column 6.

[0054] In a further optimized design, a base ring 25 is fitted and fixed on the end of the positioning post 22 near the positioning plate 16, and the base ring 25 is fixedly connected to the positioning plate 16.

[0055] The presence of the base ring 25 increases the bottom area of ​​the positioning post 22 and improves the connection strength between the positioning post 22 and the positioning plate 16. At the same time, the bottom opening position of the positioning hole 24 needs to be adapted to the base ring 25.

[0056] Further optimize the plan, referring to Figure 1 , Figure 2 , Figure 5 The second mounting platform 7 includes an upper plate 26 that is sleeved and fixed to the outer wall of the second steel column 6, and the upper plate 26 has an upper end 27 that matches the support end 13.

[0057] The upper end 27 is fitted onto the outer wall of the second steel column 6. The upper end 27 can be fixed to the outer wall of the second steel column 6 by means of bolt connection and auxiliary welding. Similarly, the fixing sleeve 10 can be fixed to the outer wall of the first steel column 1 by means of bolt connection and auxiliary welding.

[0058] The second connecting end 8 has a T-shaped structure. The flat end of the second connecting end 8 is fixedly connected to the end face of the upper end 27. The end face of the second steel beam 9 near the second connecting end 8 is provided with a second groove 28 that matches the protruding end of the second connecting end 8. The second steel beam 9 and the second connecting end 8 are fixedly connected by the second fixing bolt 29.

[0059] The upper end 27 is used to install the second connecting end 8, and the second connecting end 8 is connected to the second steel beam 9. That is, in a set of steel beams, the lower first steel beam 4 and the upper second steel beam 9 are used together.

[0060] Further optimize the plan, referring to Figure 1 , Figure 2 , Figure 4 The reinforcement includes a reinforcement plate 30 fixedly connected to the end face of the positioning end 17. A first corner piece 31 is fixedly connected to the top of the reinforcement plate 30. The two sides of the first corner piece 31 are respectively provided with first reinforcement bolts 32. The ends of the first reinforcement bolts 32 extend into the second steel beam 9 and the reinforcement plate 30 respectively.

[0061] A second reinforcing bolt 33 is provided on the side wall of the reinforcing plate 30 away from the first steel beam 4, and the end of the second reinforcing bolt 33 extends into the first steel beam 4.

[0062] Understandably, the reinforcing plate 30 is an extension of the positioning plate 5. Two reinforcing plates 30 are provided on one positioning end 17. The two reinforcing plates 30 are located between the first steel beam 4 and the second steel beam 9. At the same time, since the top of the positioning plate 5 is flush with the top surface of the support plate 11, the top of the reinforcing plate 30 is flush with the top surface of the first steel beam 4. The second steel beam 9 is located above the reinforcing plate 30. The first corner piece 31 is fixed on the reinforcing plate 30, and the first steel beam 4 and the second steel beam 9 are connected and fixed through the first corner piece 31.

[0063] Further optimize the plan, referring to Figure 1 , Figure 2 A second corner piece 34 is provided between two adjacent support ends 13. Several sets of third reinforcing bolts 12 are passed through the second corner piece 34. The two adjacent support ends 13, the two adjacent positioning ends 17, and the two adjacent upper ends 27 are fixedly connected by the second corner piece 34. The second corner piece 34 is provided on the outside of the first steel column 1 and the second steel column 6. The first mounting platform 2, the positioning plate 5, and the second mounting platform 7 are connected into an integrated structure by the second corner piece 34, which improves the connection strength of the first steel column 1 and the second steel column 6.

[0064] Specifically, the construction method is as follows:

[0065] a. Install and fix the first mounting platform 2 at the end of the first steel column 1, and install and fix the first steel beam 4 on the first connecting end 3;

[0066] b. Lay the positioning plate 5 onto the first mounting platform 2 and fix the positioning plate 5 to the first mounting platform 2;

[0067] c. Fix the second mounting platform 7 to the end of the second steel column 6, hoist the second steel column 6 so that the positioning hole 24 corresponds to the positioning column 22, and place the bottom surface of the second steel column 6 on the top surface of the positioning plate 5.

[0068] d. Install and fix the second steel beam 9 onto the second connecting end 8, and install the first corner piece 31 onto the reinforcing plate 30 to fix the first steel beam 4 and the second steel beam 9;

[0069] e. Install the second corner piece and connect the first mounting platform 2, the positioning plate 5, and the second mounting platform 7.

[0070] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
