Technical Field
[0001] This utility model relates to the field of dental endoscope technology, specifically a three-dimensional modular building structure node. Background Technology
[0002] Modular buildings have advantages such as fast construction speed, easy quality control, and minimal impact on the site environment, which are in line with the development trend of modern building industrialization.
[0003] However, the current domestic standard system for three-dimensional modular buildings is still incomplete, especially in terms of node design, where a unified standard practice has not yet been formed. Existing node designs often have many shortcomings: some nodes only focus on structural load-bearing performance, neglecting the ease of processing and manufacturing, resulting in high production difficulty and cost; other nodes, while easy to process, are difficult to position and inefficient to install on-site, requiring a large number of skilled workers for adjustment and operation, which not only increases labor costs but also makes it difficult to guarantee installation accuracy, easily leading to installation errors and affecting the overall structural performance of the building. Therefore, there is an urgent need for a connection node that can comprehensively balance the needs of structural load-bearing, processing and manufacturing, and on-site installation to promote the further development and popularization of three-dimensional modular buildings. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a three-dimensional modular building structure node, which solves at least some of the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides a three-dimensional modular building structure node. The structure node includes a first connector, a second connector, a first reinforcing plate, and a second reinforcing plate fixedly connected to each other. The first connector has a first slot extending along the X direction and a second slot extending along the Y direction, and the second connector has a third slot extending along the Z direction. The first reinforcing plate and the second reinforcing plate are both connected and disposed between the first connector and the second connector. The first reinforcing plate is disposed close to the first slot, and the second reinforcing plate is disposed close to the second slot. The X direction, Y direction, and Z direction are perpendicular to each other.
[0006] Optionally, the first connector has a notch extending in the Z direction, and the second connector extends at least partially into the notch and is welded to the portion of the first connector near the notch.
[0007] Optionally, the first connector includes an integrally formed upper horizontal plate, a first vertical plate, a second vertical plate, a first lower horizontal plate, and a second lower horizontal plate; the first vertical plate and the first lower horizontal plate both extend along the X direction, and the upper horizontal plate, the first vertical plate, and the first lower horizontal plate cooperate to form the first slot; the second vertical plate and the second lower horizontal plate both extend along the Y direction, and the upper horizontal plate, the second vertical plate, and the second lower horizontal plate cooperate to form the second slot.
[0008] Optionally, the upper horizontal plate has a first region, a second region, and a third region; the horizontal projection of the first region overlaps with the first lower horizontal plate, the horizontal projection of the third region overlaps with the second lower horizontal plate, the second region is located between the first region and the third region, and the shape of the second region is an isosceles right triangle.
[0009] Optionally, the structural node further includes a mounting component disposed on the upper horizontal plate, the mounting component being tapered.
[0010] Optionally, the structural node further includes a lifting ring disposed on the upper horizontal plate; the lifting ring is detachably connected to the upper horizontal plate.
[0011] Optionally, the second connector includes a third vertical plate and a fourth vertical plate located on the outer side; the third vertical plate is parallel to the first vertical plate, and the edge of the third vertical plate near the first vertical plate is welded and fixed to the first vertical plate; the fourth vertical plate is parallel to the second vertical plate, and the edge of the fourth vertical plate near the second vertical plate is welded and fixed to the second vertical plate.
[0012] Optionally, the first reinforcing plate is triangular in shape and has a first edge and a second edge; the first edge is welded and fixed to the lower edge of the first vertical plate, and the second edge is welded and fixed to the edge of the third vertical plate.

[0014] Optionally, the first connector is provided with a connection hole; and / or, the second connector is provided with a connection hole.
[0015] Compared with the prior art, this utility model embodiment has the following advantages: The first connector is cast with mutually perpendicular X-direction slots and Y-direction slots in the same horizontal plane to form a "cross" bidirectional socket; the second connector has only a single Z-direction slot to form a "T" socket. After the two are rigidly spliced by the first and second reinforcing plates, the node presents a "planar bidirectional + vertical single-axis" slot system layout: This allows the factory to process the relative angle and position of the cross slots at one time, ensuring that the X and Y beams are automatically orthogonal when inserted at the same time, eliminating the need for on-site square correction; only a single slot is retained vertically, reducing the secondary alignment process at the column end. When the module is lowered, the column end only needs to be aligned with a Z-direction socket to complete the vertical positioning, halving the installation steps; the first and second reinforcing plates connect the "bidirectional horizontal slot" and the "unidirectional vertical slot" to form a triangular rigid domain at the corner. The horizontal force is jointly borne by the bidirectional slots, and the vertical force is directly introduced into the single slot. The force transmission path is short and clear. The node weight is not significantly increased, but the overall rigidity is greatly improved, achieving a high-strength and fast installation effect of "multi-directional precision control + unidirectional rapid insertion".

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1 and Figure 2 As shown, this utility model provides a three-dimensional modular building structure node 1. The structural node 1 includes a first connector 10, a second connector 11, a first reinforcing plate 12, and a second reinforcing plate 13 fixedly connected to each other. The first connector 10 has a first slot 100 extending along the X direction and a second slot 101 extending along the Y direction. The second connector 11 has a third slot 110 extending along the Z direction. The first reinforcing plate 12 and the second reinforcing plate 13 are both connected and disposed between the first connector 10 and the second connector 11. The first reinforcing plate 12 is disposed close to the first slot 100, and the second reinforcing plate 13 is disposed close to the second slot 101. The X, Y, and Z directions are perpendicular to each other. The first connector 10 is cast with mutually perpendicular X-direction slots and Y-direction slots in the same horizontal plane to form a "cross" bidirectional socket. The second connector 11 has only a single Z-direction slot, forming a "T" socket. After being rigidly spliced by the first and second reinforcing plates 13, the nodes present a "planar bidirectional + vertical unidirectional" groove layout. This allows the factory to process the relative angles and positions of the cross grooves in one go, ensuring that X-beam 2 and Y-beam 3 are automatically orthogonal when inserted simultaneously, eliminating the need for on-site square correction. Only a single groove is retained vertically, reducing the secondary alignment process at the column end. When the module is lowered, the column end of Z-beam 4 only needs to be aligned with a Z-direction socket to complete the vertical positioning, halving the installation steps. The first reinforcing plate 12 and the second reinforcing plate 13 connect the "bidirectional horizontal groove" and the "unidirectional vertical groove" at the corner to form a triangular rigid domain. The horizontal force is jointly borne by the bidirectional groove, and the vertical force is directly introduced into the single groove. The force transmission path is short and clear. The node weight is not significantly increased, but the overall rigidity is greatly improved, achieving a high-strength and fast installation effect of "multi-directional precision control + unidirectional rapid insertion".
[0020] As an optional implementation, the first connector 10 has a notch 103 extending in the Z direction, and the second connector 11 at least partially extends into the notch 103 and is welded to the portion of the first connector 10 near the notch 103. The nested notch 103 allows the second connector 11 and the first connector 10 to form a double-sided weld inside, doubling the weld length but reducing the thickness and heat generation; the nesting itself provides installation guidance, allowing the module to automatically center upon falling, eliminating the need for external temporary positioning fixtures, resulting in faster installation and more reliable welding.
[0021] As an optional implementation, the first connector 10 includes an integrally formed upper horizontal plate 104, a first vertical plate 105, a second vertical plate 106, a first lower horizontal plate 107, and a second lower horizontal plate 108. The first vertical plate 105 and the first lower horizontal plate 107 both extend along the X direction, and the upper horizontal plate 104, the first vertical plate 105, and the first lower horizontal plate 107 cooperate to form a first slot 100. The second vertical plate 106 and the second lower horizontal plate 108 both extend along the Y direction, and the upper horizontal plate 104, the second vertical plate 106, and the second lower horizontal plate 108 cooperate to form a second slot 101. The integrally cast closed slot eliminates the long longitudinal welds of traditional multi-plate splicing, completely cutting off the source of welding shrinkage, and the slot size is formed in one step. The beams and columns can achieve the designed tightness upon insertion on-site, eliminating the need for trimming and shims, improving assembly efficiency, and ensuring the geometric accuracy of the nodes.
[0022] As an optional implementation, the upper horizontal plate 104 has a first region, a second region, and a third region; the horizontal projection of the first region overlaps with the first lower horizontal plate 107, the horizontal projection of the third region overlaps with the second lower horizontal plate 108, the second region is located between the first and third regions, and the shape of the second region is an isosceles right triangle. The isosceles right triangle transition zone transmits the X and Y flange force flows to each other with the shortest hypotenuse, and the local bending stress is dispersed; the shape has a built-in 45° anti-misalignment slope, which allows workers to visually determine the beam direction, avoiding reverse installation, and simultaneously improving structural strength and construction convenience.
[0023] As an optional implementation, structural node 1 also includes a mounting member 14 disposed on the upper horizontal plate 104. The mounting member 14 is tapered. The tapered mounting member 14 first guides the centering with its large end, and then forms a tight shear key immediately after the small end enters the hand hole. The centering force is provided by the weight of the module itself, eliminating the need for hydraulic jacks or pry bars, thus greatly shortening the installation time. At the same time, the cone root is cast integrally with the node, permanently providing high shear stiffness.
[0024] As an optional implementation, structural node 1 also includes a lifting ring 15 disposed on the upper horizontal plate 104; the lifting ring 15 is detachably connected to the upper horizontal plate 104. The lifting ring 15 is screwed onto the node at the factory and can be removed and sealed on-site after hoisting, eliminating the need for on-site welding of temporary lifting lugs, completely eliminating secondary heat input and surface damage caused by cutting and grinding of lifting lugs, maintaining the original precision and appearance of the node, and the cyclical use of the lifting ring 15 also reduces material consumption.
[0025] As an optional implementation, the second connector 11 includes a third vertical plate 111 and a fourth vertical plate 112 located on the outer side; the third vertical plate 111 is parallel to the first vertical plate 105, and the edge of the third vertical plate 111 near the first vertical plate 105 is welded and fixed to the first vertical plate 105; the fourth vertical plate 112 is parallel to the second vertical plate 106, and the edge of the fourth vertical plate 112 near the second vertical plate 106 is welded and fixed to the second vertical plate 106. The outer parallel vertical plates and the inner vertical plates form a double-walled box-type groove, and after the column end is embedded, a double-sided force transmission path is formed; the spacing between the wall plates is visible, making it easy to visually confirm whether the column end is tightened, the installation quality is immediately controllable, and the bending and shear stiffness of the joint is strengthened.
[0026] As an optional implementation, the first reinforcing plate 12 is triangular in shape and has a first edge and a second edge; the first edge is welded and fixed to the lower edge of the first vertical plate 105, and the second edge is welded and fixed to the edge of the third vertical plate 111. The first reinforcing plate 12 is triangular and located at the XZ corner, which connects the slot sidewall and the column wall into a unified rigid domain; the axial stiffness within the plate surface is large, which significantly reduces the shear deformation of the node under horizontal force, improves the overall stability, and the reinforcing plate and the node are cast integrally, eliminating the need for additional welding and stiffening on site, thus maintaining high precision.
[0027] As an optional implementation, the second reinforcing plate 13 is triangular and has a third edge and a fourth edge; the third edge is welded and fixed to the lower edge of the second vertical plate 106, and the fourth edge is welded and fixed to the edge of the fourth vertical plate 112. The second reinforcing plate 13 is a triangular reinforcing plate located at the YZ corner, which connects the slot sidewall and the column wall into a unified rigid domain; the axial stiffness within the plate surface is large, which significantly reduces the shear deformation of the node under horizontal force, improves the overall stability, and the reinforcing plate and the node are cast integrally, eliminating the need for on-site welding and stiffening, thus maintaining high precision.
[0028] As an optional implementation, the first connector 10 is provided with a connecting hole 16; and / or, the second connector 11 is provided with a connecting hole 16. The factory pre-processed connecting holes 16 allow for direct insertion of high-strength bolts on site to complete the final tightening, eliminating the need for on-site drilling, hole enlargement, and welding; the hole position accuracy is high, the node installation is completed in one go, and the module can be replaced or reinforced later by loosening the bolts, balancing construction speed and structural maintainability.
[0029] The steps for assembling the frame using the aforementioned structural node 1 are as follows: Position the tooling jig according to the spacing of the six Z-beams of the frame; Install six structural nodes 1 on six tooling jigs respectively; Three Y-beams 3 and four X-beams 2 are inserted into the corresponding first slot 100 and second slot 101 respectively, and welded to form the top frame; Repeat the above steps and assemble the bottom frame; After flipping the bottom frame, insert the six Z beams 4 into the corresponding third slots 110, and then weld and fix the six Z beams 4 to the corresponding structural nodes 1. After the top frame is hoisted, it is connected to the top of the six Z-beams 4 via the third slot 110. Then, the six Z-beams 4 are each welded and fixed to their corresponding structural nodes 1, thus forming a structure as shown in the figure. Figure 3 The complete framework shown.
[0030] The above-described implementation method employs standardized cast steel (welded) nodes, connected to the beam and column components of the module via plug welding / bolts (not limited to), satisfying the structural requirements for node force transmission while minimizing node welding, thus avoiding the deformation problem of welding process in structural node 1. Furthermore, during on-site installation, guide cones (structurally serving as shear keys) are installed in the lower nodes, and holes are drilled in the corresponding positions in the upper nodes. Precise positioning is achieved through the guide cones during installation, resulting in quick, convenient, and accurate installation. This significantly improves on-site installation efficiency and reduces labor costs. This structural node 1 not only meets the force transmission requirements of three-dimensional modular steel structure mechanics but also considers the transportation, hoisting, and installation of modular steel structure buildings. Through standardized node design, it reduces the cost of modular buildings, which is conducive to the promotion of modular buildings.
