Description

Technical Field

[0001] This utility model relates to a construction support structure for building engineering, specifically a bolted ball joint space frame and a support structure including the bolted ball joint space frame. Background Technology

[0002] In modern construction engineering, the application of large-span spatial structures is becoming increasingly widespread. Large-scale storage facilities, such as large-diameter coal bunkers, have roof covering structures with high requirements for load-bearing capacity and stability. The construction of the conical shell structure of a coal bunker is a challenging and crucial aspect of coal bunker engineering. Traditional support structures may suffer from insufficient structural stiffness and poor adaptability when facing complex load conditions and spatial layouts. For example, the existing space frame support platform structures used in the construction of coal bunker conical shells are all uniform-height space frame structures, meaning the upper chord spheres are all on the same horizontal plane, while the lower chord spheres are on another horizontal plane, and the web members have consistent lengths. During the construction of large-diameter coal bunker conical shells, this type of support structure struggles to adapt to the load variations at different locations during the casting of the conical shell, and cannot efficiently and evenly distribute the load during the construction process. This leads to excessive local stress on the space frame structure, affecting the safety and stability of the support platform structure. Therefore, a new type of bolted ball joint space frame and bolted ball joint space frame support structure are needed to solve these problems. Utility Model Content

[0003] One of the purposes of this invention is to provide a bolted ball joint space frame so that the bolted ball joint space frame can adapt to load changes in different parts during the casting of the conical shell, thereby enhancing the stability of the structure.

[0004] The second objective of this utility model is to provide a bolted ball joint space frame support structure, which enables the bolted ball joint space frame support structure to adapt to load changes in different parts during the casting of the conical shell, thereby enhancing the stability of the structure.

[0005] One of the objectives of this utility model is achieved as follows:

[0006] A bolted ball joint space frame, comprising:

[0007] Upper chord layer, wherein the upper chord layer is horizontally arranged;

[0008] The lower chord layer is located below the upper chord layer. The lower chord layer includes multiple inclined layers that are gradually inclined downward from the outside to the inside and whose edges are connected in sequence, as well as a flat layer connected to the edge of the lowest inclined layer.

[0009] The upper chord layer and the multiple inclined layers and flat layers are all fixedly connected by the web members.

[0010] As a further technical solution, the upper chord layer includes multiple upper chords connected end to end, and the ends of the multiple upper chords are fixedly connected by bolt balls; the multiple inclined layers and the multiple flat layers each include multiple lower chords connected end to end, and the ends of the multiple lower chords are fixedly connected by bolt balls, and the two ends of the web members are respectively fixedly connected to the bolt balls.

[0011] As a further technical solution, multiple regular square pyramids are formed between the upper chord, the lower chord, the web member, and the bolt ball.

[0012] The second objective of this utility model is achieved as follows:

[0013] A bolted ball joint space frame support structure includes a bolted ball joint space frame, and further includes:

[0014] Steel brackets, wherein there are multiple steel brackets, which are fixedly installed around the inner wall of the coal bunker cone shell;

[0015] The support base is provided in multiple units, each corresponding to a steel bracket. The support base is fixedly mounted on the steel bracket, and the outermost bolt ball of the lower chord layer is fixedly mounted on each of the multiple support bases.

[0016] As a further technical solution, the support base includes:

[0017] The transition plate is fixedly mounted on the steel bracket;

[0018] A support base plate, which is fixedly mounted on the top of the transition plate;

[0019] A double-sided rib plate, the bottom of which is fixedly disposed on the top of the support base plate, and the top of which is provided with a first arc-shaped groove corresponding to the bolt ball;

[0020] The single-sided rib plate consists of two symmetrically arranged rib plates, both of which are perpendicular to the double-sided rib plate and are fixedly disposed on both sides of the double-sided rib plate. The top of the single-sided rib plate is provided with a second arc-shaped groove corresponding to the bolt ball, and the bolt ball is fixedly disposed in the first arc-shaped groove and the second arc-shaped groove.

[0028] The beneficial effects of this utility model are:

[0029] The unique design of the bolt ball joint space frame in this utility model gives the lower chord layer a height variation characteristic. Based on the load distribution and stress characteristics generated during the construction of the large-diameter coal bunker cone shell, the stress in the edge area of ​​the cone shell is relatively small, and the lower space frame height is sufficient to meet the load-bearing requirements; while the stress in the central area is large, and the increased space frame height can improve the structural load-bearing capacity. This height variation structure can better adapt to the load changes in different parts during the casting of the cone shell, effectively reduce the deformation of the structure under vertical load, enhance the stability of the structure, and thus ensure the safety of construction on the support platform.

[0030] The bolt ball joint space frame support structure in this utility model uses support seats and steel brackets to fix the bolt ball joint space frame, making the structure stable and easy to install. Attached Figure Description

[0044] like Figures 1-5 As shown, this utility model provides a bolt ball joint space frame 11, which mainly includes an upper chord layer 1, a lower chord layer 2, and web members 3.

[0045] The upper chord layer 1 is horizontally arranged and includes multiple upper chord members 100 connected end to end. The ends of the multiple upper chord members 100 are all fixedly connected by bolt balls 4. The lower chord layer 2 is located below the upper chord layer 1 and includes multiple inclined layers 21 that are gradually inclined downward from the outside to the inside and connected at the edges, as well as a flat layer 22 connected to the edge of the lowermost inclined layer 21. The multiple inclined layers 21 and the flat layer 22 each include multiple lower chord members 200 connected end to end. The ends of the multiple lower chord members 200 are all fixedly connected by bolt balls 4. This unique design of the lower chord layer 2 with varying height can better adapt to the load changes in different parts during the casting of the conical shell, and effectively reduce the deformation of the structure under vertical loads while saving steel, thereby enhancing the stability of the structure and ensuring the safety of construction on the support platform. In this embodiment, the inclined layer 21 has three layers, namely, the lower chord layer 2 has four layers of bolt balls 4 with gradually decreasing height; the upper chord layer 1 is fixedly connected to the multiple inclined layers 21 and flat layers 22 through the web members 3, that is, the two ends of the web members 3 are fixedly connected to the bolt balls 4 respectively. Multiple square pyramids are formed between the upper chord 100, the lower chord 200, the web members 3 and the bolt balls 4. This structural form gives the bolt ball node space frame 11 good stress performance in all directions, can efficiently bear the load transmitted by the coal bunker cone shell, and greatly improve the overall stability of the bolt ball node space frame 11.

[0046] like Figures 1-11 As shown, this utility model also proposes a bolted ball joint space frame support structure, which mainly includes a steel bracket 5, a support base 6, and the aforementioned bolted ball joint space frame 11.

[0047] Multiple steel brackets 5 are fixed around the inner wall of the coal bunker cone shell, providing reliable foundation support points for the entire support structure. Multiple support seats 6 are also present, each corresponding to one of the steel brackets 5. The support seats 6 are fixedly mounted on the steel brackets 5, and the outermost bolt balls 4 of the lower chord layer 2 are fixedly mounted on multiple support seats 6.

[0048] Specifically, the support base 6 includes a transition plate 61, a support base plate 62, a double-sided rib plate 63, and a single-sided rib plate 64. The transition plate 61 is fixedly mounted on the steel bracket 5. Multiple bolts 65 are welded to the top of the transition plate 61. The support base plate 62 is located on top of the transition plate 61. The bolts 65 pass through the support base plate 62 and are locked by several nuts 66, which enhances the stability of the connection and facilitates installation and adjustment on-site according to actual conditions. The bottom of the double-sided rib plate 63 is fixedly mounted on the top of the support base plate 62. The top of the double-sided rib plate 63 has a first arc-shaped groove that matches the bolt ball 4. There are two single-sided rib plates 64 arranged symmetrically. Both single-sided rib plates 64 are perpendicular to the double-sided rib plate 63 and are fixedly mounted on both sides of the double-sided rib plate 63. The top of the single-sided rib plate 64 has a second arc-shaped groove that matches the bolt ball 4. The bolt ball 4 is fixedly mounted in the first and second arc-shaped grooves to achieve precise positioning and reliable connection. In this embodiment, a washer 67 is provided between the nut 66 and the support base plate 62. The washer 67 is inserted through the bolt 65 to ensure the nut 66 is securely locked, and at the same time to prevent the nut 66 from damaging the surface of the support base plate 62.

[0049] A purlin layer 7 can be installed at the top of the upper chord layer 1. The purlin layer 7 is fixedly connected to the bolt ball 4 of the upper chord layer 1 by a support 8. The purlin layer 7 is used to bear the load of the coal bunker cone shell and transfer it to the bolt ball node space frame 11. Specifically, the purlin layer 7 includes main purlins 71, secondary purlins 72 and a top plate 73. The bottom of the main purlins 71 is welded to the support 8. There are multiple secondary purlins 72 arranged in a row, all perpendicular to the main purlins 71 and welded to the top of the main purlins 71. The top plate 73 is made of plywood, which has high strength and good bending resistance. The top plate 73 is fixed to the top of the secondary purlins 72 by self-tapping screws.

[0050] The bolt ball joint space frame 11 in this utility model is fixed by the support base 6 and the steel bracket 5, making the structure stable and easy to install.
