Description

Technical Field

[0001] This utility model relates to the field of heavy concrete component storage construction, and in particular to a variable cross-section steel shell concrete support pier. Background Technology

[0002] Heavy concrete structures such as concrete piers, concrete bridge beams, and concrete caissons are large in volume and weight, requiring specialized sites for prefabrication and storage before being transported to the construction site using specialized transport equipment. To facilitate transport, temporary supports are typically provided for these concrete components. Traditional supports generally use square concrete piers or steel-shell concrete piers. Concrete piers are widely used in this field due to their simple construction and ease of fabrication. For large projects, concrete piers need to be reused multiple times. However, they are frequently bumped and knocked during fabrication, storage, and transportation, leading to compromised load-bearing capacity, the discarding of numerous concrete piers, resource waste, and increased construction costs. Furthermore, while concrete piers have guaranteed compressive strength, their lateral load-bearing capacity is relatively weak, posing a significant risk of failure to tall structures under wind or earthquake conditions.

[0003] The constant-section steel-shell concrete pier is a novel type of pier. It features a simple structure, convenient fabrication, and good vertical, horizontal, and bending capacity. The steel shell effectively protects the core concrete while enhancing the pier's load-bearing capacity, thus extending its service life and reducing construction costs. However, for ultra-large concrete components, in addition to considering the pier's structural strength, the bearing capacity of the foundation must also be taken into account. Simply increasing the pier's cross-section to reduce foundation pressure would significantly impact transportation and manufacturing costs. Therefore, researching a variable-section steel-shell concrete pier is necessary. Summary of the Invention

[0004] This utility model aims to solve the problems of traditional support piers being easily damaged by bumps during transportation, storage and use, having low bending and shear strength, having excessively large cross-sections when supporting ultra-large concrete components, being inconvenient to transport, and requiring pile driving for supporting the foundation, and provides a variable cross-section steel shell concrete support pier.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a variable cross-section steel shell concrete support, comprising a core concrete and an inverted T-shaped steel shell, wherein the core concrete is poured inside the steel shell, a horizontal stiffening rib plate assembly is provided at the top edge of the steel shell, a pair of reinforcing elbow plates are provided on both right-angled sidewalls of the steel shell, a lifting point is provided at the upper part of the reinforcing elbow plate, and an internal stiffening rib plate assembly is provided on the inner wall of the steel shell.

[0006] Specifically, the steel shell includes an inverted T-shaped side sealing plate, a lower vertical rectangular side sealing plate, an upper vertical rectangular side sealing plate, a horizontal rectangular side sealing plate, and a bottom sealing plate. The two inverted T-shaped side sealing plates are welded to the top two sides of the bottom sealing plate. The lower vertical rectangular side sealing plate is welded to the lower vertical edge of the two inverted T-shaped side sealing plates and the bottom sealing plate. The upper vertical rectangular side sealing plate is welded to the upper vertical edge of the two inverted T-shaped side sealing plates. The horizontal rectangular side sealing plate is welded to the inverted T-shaped side sealing plate, the lower vertical rectangular side sealing plate, and the upper vertical rectangular side sealing plate.

[0007] Specifically, the horizontal stiffening rib assembly includes horizontal transverse stiffening ribs welded to the top of the upper vertical rectangular side plate and the inverted T-shaped side plate, as well as horizontal longitudinal stiffening ribs welded to the ends of the horizontal transverse stiffening ribs.

[0008] Specifically, the internal stiffening rib assembly includes several first stiffening ribs welded to the inner wall of the upper vertical rectangular side sealing plate, several second stiffening ribs welded to the inner wall of the lower vertical rectangular side sealing plate, a third stiffening rib welded to the middle of the inner wall of the inverted T-shaped side sealing plate, and a fourth stiffening rib welded between the opposite surfaces of the horizontal rectangular side sealing plate and the bottom sealing plate. The fourth stiffening ribs are welded to the inner wall of the inverted T-shaped side sealing plate, and the top of the bottom sealing plate is respectively welded with fifth stiffening ribs that connect to the bottom of the two opposite fourth stiffening ribs and the bottom of the two opposite third stiffening ribs.

[0009] Specifically, the first stiffening rib is welded and fixed to the horizontal transverse stiffening rib.

[0010] In particular, the reinforcing elbow plate corresponds exactly to the first stiffening rib on the inner side of the upper vertical rectangular side sealing plate.

[0011] The beneficial effects of this utility model are:

[0012] This invention provides higher vertical bearing capacity, horizontal shear strength, and bending resistance, effectively improving the wind and earthquake resistance of the pier.

[0013] This invention can effectively transfer the load of the support structure, reduce the pressure on the foundation under the pier, and the foundation only needs to be compacted in accordance with conventional pad beams for safe use, thus saving a lot of foundation treatment costs.

[0014] The external reinforcing elbow plate of this utility model enhances the bending resistance of the pier in this direction, effectively improving the stability of the pier, and the top lifting lug facilitates the overall hoisting and transportation.

[0015] This invention effectively protects the core concrete with a comprehensive protective steel shell, avoiding the risk of concrete damage during use and storage, effectively extending the service life of the support pier, and reducing construction costs.

[0016] This utility model has a simple structure, is easy to construct, and does not require additional casting templates, thus effectively reducing construction costs. Attached Figure Description

[0021] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] like Figures 1-3 As shown, a variable cross-section steel-shell concrete pier includes a core concrete 1 and an inverted T-shaped steel shell 2. The core concrete 1 is poured inside the steel shell 2. A horizontal stiffening rib assembly 3 is provided at the top edge of the steel shell 2. A pair of reinforcing elbow plates 4 are provided on each of the right-angled side walls of the steel shell 2. Lifting points 5 are provided on the upper part of the reinforcing elbow plates 4. An internal stiffening rib assembly 6 is provided on the inner wall of the steel shell 2. During construction, the pier can be placed on the designated foundation in the required direction using a forklift or lifting points 5. After laying rubber bearings on the top of the pier, the heavy concrete structure to be supported can be hoisted onto the pier.

[0024] The steel shell 2 includes an inverted T-shaped side sealing plate 21, a lower vertical rectangular side sealing plate 22, an upper vertical rectangular side sealing plate 23, a horizontal rectangular side sealing plate 24, and a bottom sealing plate 25. The two inverted T-shaped side sealing plates 21 are welded to the top two sides of the bottom sealing plate 25. The lower vertical rectangular side sealing plate 22 is welded to the lower vertical edge of the two inverted T-shaped side sealing plates 21 and the bottom sealing plate 25. The upper vertical rectangular side sealing plate 23 is welded to the upper vertical edge of the two inverted T-shaped side sealing plates. The horizontal rectangular side sealing plate 24 is welded to the inverted T-shaped side sealing plate 21, the lower vertical rectangular side sealing plate 22, and the upper vertical rectangular side sealing plate 23.

[0025] The horizontal stiffening rib assembly 3 includes horizontal transverse stiffening ribs 31 welded to the top of the upper vertical rectangular side plate 23 and the inverted T-shaped side plate 21, and horizontal longitudinal stiffening ribs 32 welded to the ends of the horizontal transverse stiffening ribs 31. After the variable cross-section steel shell 2 is manufactured, the core concrete 1 is filled into the interior of the variable cross-section steel shell 2 and compacted by vibration. It is necessary to ensure that the top surface of the core concrete 1 is consistent with the flatness of the horizontal stiffening rib assembly 3.

[0026] The internal stiffening rib assembly 6 includes several first stiffening ribs 61 welded to the inner wall of the upper vertical rectangular side sealing plate 23, several second stiffening ribs 62 welded to the inner wall of the lower vertical rectangular side sealing plate 22, a third stiffening rib 63 welded to the middle of the inner wall of the inverted T-shaped side sealing plate 21, and a fourth stiffening rib 64 welded between the opposite surfaces of the horizontal rectangular side sealing plate 24 and the bottom sealing plate 25. The fourth stiffening rib 64 is welded to the inner wall of the inverted T-shaped side sealing plate 21. The top of the bottom sealing plate 25 is respectively welded with fifth stiffening ribs 65 that connect to the bottom of the two opposite fourth stiffening ribs 64 and the bottom of the two opposite third stiffening ribs 63. The first stiffening ribs 61 are welded and fixed to the horizontal transverse stiffening ribs 31. The reinforcing elbow plate 4 corresponds to the first stiffening ribs 61 on the inner side of the upper vertical rectangular side sealing plate 23.

[0027] In operation, the steel shell 2 is welded sequentially into an inverted T-shaped structure, and then the core concrete 1 is injected. After the core concrete 1 is vibrated and compacted to the required strength, it can be transported to a designated location in the prefabrication yard via lifting points 5 located at the external reinforcing elbow plate 4. After adjusting the orientation of the support pier according to usage requirements, the heavy component can be effectively supported. After the heavy concrete structure is transported, the support pier can be hoisted and stacked in a designated storage area for future use.

[0028] This pier adopts an inverted T-shaped steel-shell concrete structure, which can effectively support heavy components and reduce foundation pressure. The unique feature of this steel-shell concrete pier is that the angle between the rectangular diagonal and vertical of the outward-extending horizontal section of the inverted T-shaped steel plate is the concrete stress diffusion angle. This variable cross-section steel-shell concrete pier provides high vertical bearing capacity, horizontal shear strength, and bending resistance, effectively improving the pier's wind and earthquake resistance. This variable cross-section steel-shell concrete pier can fully transfer the load of the supported structure, effectively reducing the foundation pressure under the pier. The foundation only requires conventional compaction treatment and conventional support beams for safety. The use of this variable cross-section steel-shell concrete pier saves a significant amount of foundation treatment costs; the external reinforcing elbow plate 4 enhances the pier's bending resistance in this direction, effectively improving the pier's stability, and the top lifting point 5 facilitates overall hoisting and transportation; the variable cross-section steel-shell concrete pier effectively protects the core concrete 1 through the all-around protective steel shell 2, avoiding the risk of concrete damage during use and storage, and effectively extending the pier's service life and reducing construction costs; the variable cross-section concrete pier has a simple structure, is easy to construct, and does not require additional pouring formwork, effectively reducing construction costs.
