Description

Technical Field

[0001] The invention relates to the technical field of modular steel structure buildings, in particular to a modular node for coordinated force bearing of beams and columns and an installation method thereof. Background Art

[0002] Modular construction refers to a form of construction in which modular units are prefabricated in a factory and transported to the construction site for assembly. The prefabrication ratio is usually more than 85%. During the foundation engineering and site leveling, the contractor can simultaneously build components in the factory to achieve parallel progress of the process, thereby significantly shortening the construction period. As an advanced product of prefabricated buildings, modular buildings show broad development prospects with their advantages such as fast installation, excellent engineering quality, resource conservation and environmental protection. After the unit components of modular buildings are installed in the factory, they are transported to the construction site for assembly only. This method greatly simplifies on-site construction and reduces the impact of weather, labor and construction site restrictions. According to the main building materials, modular buildings can be divided into prefabricated concrete modules, wooden structure modules and the most widely used steel structure modules.

[0003] The modular units themselves have good mechanical properties, but how to reliably connect these units into a whole is still a key issue. Therefore, nodes are the key in the design of modular steel structure buildings, and the reliability of module connections directly affects the overall performance of the structure. The node design must ensure the safety and stability of the structure, while having a reasonable structure, facilitating construction, and matching the decoration and use functions inside the module. However, in the existing modular connection design, the connection integrity is poor, and there is a lack of effective connection between adjacent beams and adjacent columns, which makes them unable to coordinate stress and deformation.

Figure 8As shown, the modular connection nodes of the steel structure also include: a corner node, which is used to connect two adjacent side column nodes 4. Specifically, the corner node is an I-shaped steel column 19, and the second frame columns 13 of the two adjacent side column nodes 4 are respectively connected to the ribs and webs of the I-shaped steel column 19, and the frame column 12, the first frame beam 8 and the second frame beam 13 are all reserved with multiple bolt holes; the two side column upper modules 6 are consistent with the side column lower module 5 in structure, the two side column lower modules 5 are connected back to back, and the two side column upper modules 6 are symmetrically connected to the side column lower module 5 up and down; as shown Figure 2 As shown, the side of each connecting plate used for contacting the column beam is configured as a corrugated structure with multiple plow grooves, and multiple connecting plates are provided with bolt holes and matching fixing bolts, which are used for connecting beams and beams, beams and columns, and columns and columns in the middle column node 1 and the side column node 4. The beams and columns of the middle column node 1 and the side column node 4 are connected by connecting plates with corrugated plate structures.

The method for connecting modular nodes with coordinated force between beams and columns according to claim 1, characterized in that: The following steps are involved: S1 installs the center column node (1); S11: the center column lower module (2) and the center column upper module (3), spot welding the connecting plates on the side of the first frame beam (8) and the center column frame column (7); S12: installing the middle lower modules one by one through the connection plates, and fixing a plurality of middle column frame columns (7) and a plurality of first frame beams (8) through their respective corresponding connection plates; S13, by fixing the connection plate of the center column frame column (7), the upper modules are installed one by one on the installed center column lower module (2), and the installation method of the plurality of center column frame columns (7) and the plurality of first frame beams (8) of the center column upper module (3) is consistent with that of the center column lower module (2); S2 installs the side column node (4); S21 The side column lower module (5) and the side column upper module (6) are transported to the site and spot welded to the connecting plate; S22 connects the side column lower modules (5) one by one through the connecting plates; S23 installs the side column upper modules (6) one by one on the installed side column lower modules (5) by fixing the connecting plates of the side column frame columns (12).

8. The method for connecting modular nodes with coordinated force between beams and columns according to claim 7, characterized in that: The following steps are also included: After the installation and connection of the center column lower module (2) is completed in S12, a positioning device (18) is provided at a connection plate of the installed center column lower module (2) for connecting the center column upper module (3) to align the plurality of center column lower modules (2); After the installation and connection of the side column lower module (5) is completed in S22, a positioning device (18) is set at the connection plate of the installed side column lower module (5) for connecting the side column upper module (6) to align the side column lower modules (5).

9. The method for connecting modular nodes with coordinated force between beams and columns according to claim 8, characterized in that: The positioning device (18) comprises: two trapezoidal blocks (181) and a fastening bolt (182); the two trapezoidal blocks (181) are symmetrically arranged, each trapezoidal block (181) is provided with a through hole, and the through hole passes through two parallel surfaces of the trapezoidal block (181); In S12, the fastening bolt (182) passes through the hole of one trapezoidal block (181), is inserted into the bolt hole of the second cross connecting plate (10), and then passes out from the through hole of the other trapezoidal block (181). The two trapezoidal blocks (181) are brought closer together by the fastening bolt (182). After the connection between the middle column upper module (3) and the middle column lower module (2) is completed, the positioning device (18) is removed and the fastening bolt (182) is replaced by a fixing bolt. In S22, the fastening bolt (182) passes through the hole of one trapezoidal block (181), is inserted into the bolt hole of the T-shaped connecting plate (15), and then passes out from the through hole of the other trapezoidal block (181). The two trapezoidal blocks (181) are brought closer to each other by the fastening bolt (182). When the connection between the side column upper module (6) and the side column lower module (5) is completed, the positioning device (18) is removed and the fastening bolt (182) is replaced by a fixing bolt.
