Description

Technical Field

[0001] The invention belongs to the technical field of assembled steel structure buildings, and in particular relates to a rotary slider type module steel structure node and a construction method thereof. Background Art

[0002] Modular steel structure building is a fully prefabricated building system, which divides the building into multiple independent modular units. The building, structure, enclosure, water, electricity and decoration of the modular units are all self-contained and completed in the factory. On-site, only the nodes between the modular units need to be simply assembled to form an overall structure. This system has significant advantages in prefabrication rate and construction speed. Factory prefabrication and on-site assembly can be carried out simultaneously, and the demand for labor on site and the impact on the environment are extremely small.

[0003] Due to its unique construction method, modular steel structure has different structural composition and structural system from traditional steel frame structure. The construction is mainly reflected in the splicing of nodes between module units, which requires fast and reliable combination and splicing of multiple beams and columns between units. In particular, to ensure the strength and rigidity of the module unit substructure and the vertical bearing capacity of the overall modular steel structure, the modular steel structure unit column is often constructed with square steel tubes. The closed cross-section structure of square steel tubes will make the traditional bolt and node plate connection method lack effective construction operation space, affecting assembly efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rotary slider type modular steel structure node and a construction method thereof which is convenient and quick in on-site splicing construction, requires little space for node splicing operation, and can be quickly assembled.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A rotary slider type modular steel structure node, comprising an upper module column, a lower module column, a horizontal connecting plate, a shear block, a rotary slider system and a rotary sheet; a bottom sealing plate is welded to the bottom of the upper module column, a bottom sealing plate square hole is opened on the bottom sealing plate, and an operation hole is opened on the side wall of the upper module column; a top sealing plate is welded to the top of the lower module column; a connecting plate square hole is opened on the horizontal connecting plate; the shear block is welded to the top sealing plate, and a circular slide groove and an anchor bolt rod are provided on the shear block, and the anchor bolt rods are four and evenly distributed on the outside of the circular slide groove, and locking holes are opened on the circular slide groove at the positions corresponding to the anchor bolt rods; the rotary slider system comprises a rotary slider and a sliding pin, a long screw hole is opened in the middle section of the rotary slider, and a circular groove is opened at the end There are four rotating sliders, which are respectively passed through the anchor bolt rods through the long screw holes and placed on the shear block. The sliding pin is installed at the end of the rotating slider and placed in the circular slide groove of the shear block. The rotating slider is fastened by a nut; the rotating plate is provided with a central square hole and a circular hole matching the sliding pin, and the rotating plate is sleeved on the sliding pin; when splicing on site, the horizontal connecting plate and the bottom sealing plate of the upper module column are successively sleeved on the shear block, and the rotating wrench is passed through the operating hole of the side wall of the upper module column. The end of the rotating wrench is embedded in the central square hole of the rotating plate and drives the rotating plate to rotate. The rotating plate pulls the sliding pin to slide to the locking hole, and the rotating slider rotates and opens under the sliding traction of the sliding pin to realize the embedding of the bottom sealing plate of the upper module column.

[0007] Furthermore, the height of the shear block is the sum of the thickness of the horizontal connecting plate and the bottom sealing plate of the upper module column.

[0008] Furthermore, the anchor bolt rod is firmly connected to the shear block by welding.

[0009] Furthermore, the diameter of the long screw hole is 1-2 mm larger than the diameter of the anchor bolt rod.

[0010] Furthermore, the circular groove at the end of the rotating slider may be replaced by a circular hole.

[0011] Furthermore, the bottom of the sliding pin is a hemispherical surface, which is conducive to sliding in the circular sliding groove of the shear block.

[0012] Furthermore, when the rotating slider is retracted, its outer edge is flush with the outer edge of the shear block or is located within the outer edge range of the shear block. When the upper module unit is installed, the bottom cover plate of the upper module column can pass through the rotating slider system and be sleeved on the outside of the shear block; when the sliding pin slides along the circular slide groove and drives the rotating slider to rotate and open, its outer edge extends outside the edge of the shear block, thereby realizing the embedding of the bottom cover plate of the upper module column.

[0013] Furthermore, the end of the rotating wrench is a square column that matches the central square hole of the rotating piece.

[0014] A construction method for a rotary slider type modular steel structure node comprises the following steps:

[0015] (1) In the factory, the anchor bolt is welded to the shear block, the shear block is welded to the center of the top sealing plate of the lower module column, and the top sealing plate is welded to the top of the lower module column;

[0016] (2) At the construction site, install the rotating slider system, put the rotating slider on the anchor bolt rod, pass the sliding pin through the circular groove at the end of the rotating slider, and place it in the circular groove of the shear block. Adjust the position and angle of the rotating slider so that the outer edge of the rotating slider system is flush with the outer edge of the shear block or is within the outer edge range of the shear block;

[0017] (3) Install nuts on the anchor bolts to limit the vertical displacement of the rotating slider system;

[0018] (4) Put the rotating plate on the sliding pin;

[0019] (5) Install the horizontal connecting plate and put the square hole of the connecting plate outside the shear block;

[0020] (6) Install the upper module column so that the square hole of the bottom cover plate of the upper module column is placed outside the shear block;

[0021] (7) Insert the rotating wrench through the operating hole on the side wall of the upper module column, and insert the end of the rotating wrench into the central square hole of the rotating plate. The rotating plate is driven to rotate by the rotating wrench, and the sliding pin is pulled to slide along the circular slide groove, driving the rotating slider to rotate and open outward until the sliding pin falls into the locking hole to complete the fixation of the rotating slider position, thereby realizing the embedding of the bottom cover plate of the upper module column.

[0022] The beneficial effects of the present invention are as follows: by setting a shear block, a rotating slider system and a rotating sheet, the upper and lower module columns are embedded by closing and opening the rotating slider of the rotating slider system; during on-site construction, only a rotating wrench is required to simply rotate the rotating sheet and the rotating slider system to achieve connection and locking of the module columns; small construction operation space requirements and small node gaps are required; and on-site construction operations are simple and fast, and can be quickly assembled.
