Description

Technical Field

[0001] The present invention relates to the field of building construction engineering, and in particular to a modular support system for a silo concrete structure. Background Art

[0002] In the 1990s, my country began to build large-scale national grain reserve warehouses, among which shallow circular silos are a typical warehouse type (shallow circular silos are cylindrical ground grain silos with a ratio of silo wall height to inner diameter less than 1.5). Previously, most shallow circular silos on the market had a diameter of 25m to 29m. With the development of the economy and society, shallow circular silos with a diameter of 32m have appeared in recent years, and silos with larger diameters may appear in the future.

[0003] In the early days, the support system for silo roof construction used a full-floor support system with traditional steel pipe fasteners, which had shortcomings such as a long erection period, a large demand for steel pipe fasteners, and a large amount of demolition work. With the development of engineering construction technology, the support system for silo roofs has gradually evolved from a traditional vertical support system to a spatial horizontal support system. The existing pure spatial horizontal support system uses a rigid connection, that is, one end of the horizontal support rod is fixedly connected to the inner wall of the silo structure, and the other end is fixedly connected to the middle support member. This makes the pure spatial horizontal support system only applicable to the support of silo structures of one size, and has poor adaptability. When support is required for silo structures of different diameters and different roof heights, a horizontal support system of corresponding size needs to be set up, which increases costs and is relatively wasteful of materials. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a modular support system for a silo concrete structure to solve the problem of poor adaptability of the existing horizontal support system.

[0005] The technical solution to achieve the above purpose is:

[0006] The present invention provides a modular support system for a silo concrete structure, wherein a platform structure is provided at the bottom of the silo concrete structure. The modular support system comprises:

[0011] An upper connecting plate is buckled at the end of the truss unit close to the central column. The upper connecting plate is also ring-shaped and is tightly connected to the lower connecting plate to clamp the end of the corresponding truss unit.

This makes the support system of the present invention widely applicable, enabling fully assembled construction for silos of varying diameters. Furthermore, the position of the support bracket connection on the center column is adjustable, thus meeting the support requirements of silos of varying heights.

[0017] The through holes on the upper ring plate are aligned with the connecting holes on the outer connecting edge, and then the upper ring plate and the outer connecting edge are fastened and connected by bolts passing through the corresponding through holes and connecting holes.

[0018] A further improvement of the modular support system of the silo concrete structure of the present invention is that a stiffening plate is connected between the inner side of the lower connecting plate and the supporting corbel.

[0019] A further improvement of the modular support system of the silo concrete structure of the present invention is that the truss unit includes two non-standard end sections and a plurality of standard sections connected between the two end non-standard sections.

Furthermore, a connecting plate is provided at the top of the center column to connect to the support bracket, and the mounting position of the support bracket can be adjusted to meet the construction requirements of silos of different heights. The modular support system of the present invention enables fully assembled construction, achieving a one-time investment and permanent benefits, facilitating the rapid selection of top shell support solutions for silos of different diameters, and enabling the reuse of materials to save costs.

[0046] In a specific embodiment of the present invention, Figure 8 As shown, the connecting slot 231 is vertically arranged; the connecting protrusion is also vertically arranged.

The force direction of the truss unit 24 is vertically downward, and its own gravity is also vertically downward. The connecting protrusion and the connecting slot 231 are also vertically arranged, which can ensure the connection stability between the truss unit 24 and the supporting corbel 22 and ensure operational safety.

[0048] In a specific embodiment of the present invention, Figure 2 and Figure 4 As shown, the top of the lower connecting plate 23 is provided with an inner connecting edge 233 protruding inwardly and an outer connecting edge 234 protruding outwardly, and a plurality of connecting holes are provided at intervals on the inner connecting edge 233 and the outer connecting edge 234;

[0049] The upper connecting plate 25 includes an upper ring plate 252 disposed on the corresponding end of the truss unit 24, a side ring plate 253 vertically connected to the upper ring plate 252, and a lower ring plate 254 vertically connected to the bottom of the side ring plate 253. The side ring plate 253 is disposed near the end of the truss unit 24. A plurality of through holes are provided at intervals on the upper ring plate 22 and the lower ring plate 254.

[0050] The lower ring plate 254 is attached to the inner connecting edge 233 and the through holes on the lower ring plate 254 are aligned with the connecting holes on the inner connecting edge 233. Then, bolts passing through the corresponding through holes and connecting holes are used to fasten the lower ring plate 254 and the inner connecting edge 233.

[0051] The through holes on the upper ring plate 252 are aligned with the connection holes on the outer connecting edge 234 , and the upper ring plate 252 and the outer connecting edge 234 are fastened together by bolts passing through the corresponding through holes and connection holes.

[0052] Furthermore, the positions of the bolts provided on the upper ring plate and the outer connecting edge are staggered with the positions of the truss units 24 .

[0053] In a specific embodiment of the present invention, Figure 2 and Figure 5 As shown, a stiffening plate 27 is connected between the inner side of the lower connecting plate 23 and the supporting corbel 22 .

[0054] Preferably, the stiffening plate 27 is a triangular plate, which abuts against the connection between the lower connecting plate 23 and the supporting corbel 22 and is fixed to the lower connecting plate 23 and the supporting corbel 22 by welding.

[0055] In a specific embodiment of the present invention, Figure 2 and Figure 3As shown, the lower connecting plate 23 and the upper connecting plate 24 are formed by docking two semicircular parts, and docking plates 232 and 251 are provided at the docking points. The docking plates 232 and 251 on the two semicircular parts are aligned and then fastened together by inserting bolts.

[0056] Preferably, the lower connecting plate 23 is a box beam, and a downwardly recessed connecting slot 231 is provided on the top of the box beam.

[0057] In a specific embodiment of the present invention, Figures 7 to 9 As shown, the truss unit 24 includes two non-standard end sections 241 and a plurality of standard sections 242 connected between the two non-standard end sections 241 . The length of the truss unit 24 can be adjusted according to the number of standard sections 242 to adapt to silo concrete structures 10 of different sizes.

[0058] Preferably, each standard section 242 is composed of a chord rod, a vertical rod and an oblique rod. The length of the standard section 242 has multiple specifications and can be selected according to actual needs. The length of the standard section 242 is preferably 3m and 2m.

[0059] The end non-standard section 241 includes a horizontal rod and an oblique rod supported and connected to the bottom of the horizontal rod; the connecting protrusion is provided at the end of the horizontal rod of the end non-standard section 241 close to the center column 21, and the end of the horizontal rod of the end non-standard section 241 close to the center column 21 is placed on the lower connecting plate 23.

[0060] The length of the end non-standard section 241 is planned to be 1m and 1.5m, which can be selected according to actual needs.

[0061] Thus, for a 32m diameter silo, a truss unit can be assembled from three 3m standard sections + two 1.5m end non-standard sections; for a 31m diameter silo, a truss unit can be assembled from three 3m standard sections + one 1.5m end non-standard section + one 1m end non-standard section; and for a 30m diameter silo, a truss unit can be assembled from three 3m standard sections + two 1m end non-standard sections. By adjusting the combination of standard and non-standard sections, the truss modularity can be met for silos of different diameters.

[0062] Truss pins can be used to achieve splicing connection between standard sections of the truss unit of the present invention and between a standard section and an end non-standard section.

[0063] When the truss unit 24 is connected to the silo concrete structure 10, a connection hole is first set on the inner wall of the silo concrete structure 10, and then the end of the horizontal rod of the non-standard section corresponding to the end of the truss unit 24 is inserted into the connection hole, thereby completing the connection between the truss unit 24 and the silo concrete structure 10.

[0064] In one embodiment of the present invention, the number of truss units 24 can be adjusted according to the height of the silo concrete structure 10 .

[0065] When adjusting the number of truss units, there is no need to replace the upper and lower connecting plates. The lower connecting plate is connected to the end of the truss unit by a snap-on connection, which can adapt to the construction needs of silos of different diameters and heights.

[0066] In a specific embodiment of the present invention, Figure 2 As shown, a pair of clamping plates 221 are provided on the supporting corbel 22 corresponding to the connecting plate 212. The clamping plates 221 are vertically arranged and the spacing between the pair of clamping plates 221 is adapted to the thickness of the connecting plate 212.

[0067] The clamping plate 221 is provided with a plurality of bolt holes;

[0068] The connecting plate 212 is also provided with a plurality of bolt holes;

[0069] The clamping plate 221 is connected to the corresponding bolt holes on the connecting plate 212 to adjust the installation position of the supporting bracket 22.

[0070] The supporting corbel 22 is connected to the connecting plate on the center column with high-strength bolts. The tightening of the bolt connection is divided into initial tightening and final tightening, and is completed within 24 hours. After tightening, a small hammer is used to knock the bolts one by one and random torque inspections are carried out to ensure the quality of the connection.

[0071] In a specific embodiment of the present invention, Figure 1 and Figure 10 As shown, the central column 21 includes a plurality of column units 211 that are butt-connected.

[0072] Each end of column unit 211 is equipped with a flange 2111, and a rib 2112 is provided at the connection between flange 211 and column unit 211. When docking, the flanges 2111 of the two column units 211 are aligned and then secured with bolts. The number of column units 211 can be determined based on the desired height of center column 21.

[0073] Furthermore, if Figure 1 、 Figure 11 and Figure 12 As shown, a reinforcement frame 28 is provided on the platform node 12 at the bottom corresponding to the center column 21 .

[0074] The reinforcement frame 28 includes two vertically connected H-shaped steels. The H-shaped steels are used to increase the contact surface between the center column and the platform structure. If the H-shaped steels and the platform structure are uneven, pads can be used for leveling.

[0075] In a specific embodiment of the present invention, Figure 1 As shown, in order to improve the structural stability of the central column 21 , a connecting cable 26 is tied between the bottom of the silo 11 and the middle of the central column 21 .

[0076] The present invention adopts a rotatable central column, and the height of the top supporting bracket can be adjusted to meet the needs of silos of different heights;

[0077] The present invention adopts a special adjustable universal connecting plate (i.e., an upper connecting plate and a lower connecting plate structure). When facing silos with different diameters, there is no need to replace the central support disc, and it can meet the connection needs of trusses with different numbers. It can be reused and realize modular construction.

[0078] The upper connecting plate and the lower connecting plate of the present invention are fastened and connected by bolts, and compared with ordinary pin connections, the node is safer and more firm.

[0079] The present invention adopts relatively common materials for prefabrication, processing and assembly, which is simple, fast and cost-effective to operate.

[0080] For the construction of large-diameter silo cones, a platform support system for silo cones with diameters ranging from 25 to 36 meters can be designed using standardized truss pieces and round tubes as the primary materials, supplemented by a small number of modular non-standard sections and a specially designed adjustable universal connecting plate (which can accommodate different numbers of trusses without replacing the center support plate). This system is connected by bolts and pins, using standardized truss pieces and round tubes as the primary materials, supplemented by a small number of modular non-standard sections and a specially designed center connecting plate. This system allows for fully prefabricated construction of silo cones with diameters above 25 to 36 meters, achieving "one-time investment, permanent benefits." This system also creates a data resource library to facilitate the rapid selection of cone support solutions for silos of different diameters. This allows for cost-saving material reuse and enables fully prefabricated construction of silos of varying diameters.

[0081] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
