Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an ultra-thick base plate concrete reinforcement support. Background Technology

[0002] Linear accelerators produce high-energy X-rays and electron beams with strong penetrating power. Linear accelerators and their auxiliary equipment are heavy, and their operation generates significant heat and noise. Therefore, the floor, walls, and roof of the accelerator room are typically designed as ultra-thick, large-volume concrete structures to reduce radiation leakage, prevent settlement and foundation deformation, and effectively reduce the impact of equipment noise and heat on the external environment.

[0003] In construction engineering, the positioning and fixing of upper and lower layers of reinforcing steel is a critical issue during the construction of large-volume concrete foundation slabs and thick concrete slabs. Typical steel reinforcement supports are usually made of 22mm or 25mm diameter steel bars welded into A-frame shapes or constructed as stirrups, with the upper main reinforcement bars of the raft slab then welded to the supports. Due to the large thickness of the foundation slab and the significant spacing between the upper and lower layers of reinforcing steel, workers often need to erect platforms for operation. This makes the installation and dismantling process complex and inefficient. Furthermore, excessively high steel stirrups or supports can compromise the safety and stability of the support system, easily leading to deviations in the position of the reinforcing steel and affecting the overall quality of the concrete structure.

[0004] Therefore, it is necessary to study a reinforced concrete support for ultra-thick base slabs. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an ultra-thick base plate concrete reinforcement support, which can effectively solve the problems of low construction efficiency and easy deviation of reinforcement position caused by traditional supports.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A reinforced concrete support for an ultra-thick base slab includes columns, diagonal braces, a top crossbeam, and a middle crossbeam. The columns are evenly spaced along the front-to-back and left-to-right directions, and diagonal braces are fixedly connected between adjacent left and right columns and between adjacent front and back columns to form a three-dimensional frame structure. A central crossbeam is fixedly connected to the middle of the column to support the central reinforcing bars. The top of the column is horizontally fixedly connected to a top beam for supporting the top reinforcing bars.

[0007] Furthermore, the top crossbeam is fixedly connected between two adjacent left and right columns and is arranged at intervals along the front-back direction; The central crossbeam is fixedly connected between two adjacent front and rear columns and is arranged at intervals along the left and right directions.

[0008] Furthermore, the cross-sections of the column, the top beam, and the middle beam are all L-shaped.

[0009] Furthermore, it also includes a support component, which includes a connecting part and a supporting part. The connecting part is vertically fixed to the middle of the column, and the supporting part is horizontally fixed to the top of the connecting part. The middle crossbeam is erected on the supporting part and fixedly connected to the supporting part.

[0010] Furthermore, the column includes an upper column and a lower column. Both the upper column and the lower column are vertically spaced and have several adjustment holes. Connectors are inserted into the adjustment holes to detachably connect the upper column and the lower column and allow them to be adjusted up and down.

[0011] Furthermore, an anti-slip pad is fixedly connected to the bottom of the column.

[0012] Furthermore, two sets of diagonal braces are fixedly connected between the two adjacent columns, and the two sets of diagonal braces are arranged in a crisscross pattern.

[0013] The beneficial effects of the above technical solution are: This utility model utilizes a three-dimensional frame structure comprised of columns, diagonal braces, a top crossbeam, and a middle crossbeam. The columns are evenly arranged in both longitudinal and transverse directions, while the diagonal braces are intersecting between adjacent columns to form the three-dimensional frame structure. A middle crossbeam is horizontally fixedly connected to the middle of each column, and a top crossbeam is horizontally fixedly connected to the top of each column. These components, working in conjunction with the diagonal braces, significantly improve the shear and lateral displacement resistance of the three-dimensional frame structure, preventing displacement of the support structure during concrete pouring. The middle crossbeam directly supports the middle reinforcing bars, and the top crossbeam directly supports the top reinforcing bars, replacing the traditional trestle support method. This effectively solves the problems of low construction efficiency and easy deviation in the position of reinforcing bars caused by traditional supports, ensuring that the reinforcing bars are laid flat and accurately positioned. This significantly improves the shear and lateral displacement resistance of the top and middle reinforcing bars, preventing displacement of the reinforcing bars during concrete pouring.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: This embodiment aims to provide an ultra-thick base plate concrete reinforcement support, which is mainly used for the construction of the base plate of a linear accelerator machine room, addressing the problems of low construction efficiency and easy deviation of reinforcement position caused by traditional supports.

[0017] A type of ultra-thick base slab concrete reinforcement support, such as Figure 1-4 The system includes columns 1, diagonal braces 2, a top beam 3, and a middle beam 4. Columns 1 are evenly spaced along the front-to-back and left-to-right directions. Diagonal braces 2 are fixedly connected between adjacent left-to-right and front-to-back columns 1 to form a three-dimensional frame structure for stable installation on the foundation layer 10. The diagonal braces 2 are made of C25 steel bars. Two sets of diagonal braces 2 are fixedly connected between adjacent columns 1, and these two sets of diagonal braces 2 are arranged crosswise to form a scissor brace structure, connecting the bottom and top of adjacent columns 1 together to further improve stability.

[0018] A central horizontal beam 4 is fixedly connected to the middle of column 1 to support the central reinforcing bars 5 of the raft slab structure; a top horizontal beam 3 is fixedly connected to the top of column 1 to support the top reinforcing bars 6 of the raft slab structure. The cross-sections of column 1, top beam 3, and central beam 4 are all L-shaped, allowing the use of angle steel with dimensions meeting the requirements. Compared to traditional cylindrical threaded reinforcing bars, the L-shaped cross-section structure has greater load-bearing capacity and stronger resistance to lateral tensile deformation, effectively addressing the risk of significant bending deformation of the reinforcing bars due to their length. Furthermore, the L-shaped cross-section structure provides a larger contact area with the concrete after pouring compared to cylindrical reinforcing bars, effectively improving the overall quality of the concrete structure, making it particularly suitable for ultra-thick foundation slab concrete construction.

[0019] As shown in the figure, the top beam 3 is fixedly connected between two adjacent columns 1 on the left and right, and is arranged at intervals along the front and back direction; the middle beam 4 is fixedly connected between two adjacent columns 1 on the front and back, and is arranged at intervals along the left and right direction. That is, both the top beam 3 and the middle beam 4 are arranged in only one direction. While ensuring the support of the steel bars, the amount of steel used for the beams is reduced, thus reducing construction costs. The direction of the top beam 3 and the direction of the middle beam 4 are kept perpendicular to each other, which enhances the ability of the three-dimensional frame structure to resist lateral displacement and makes the entire raft slab reinforcement system more stable.

[0020] like Figure 5 and Figure 6 It also includes a support member 8, which is T-shaped and can use angle brackets of appropriate size. The support member 8 includes an integrally formed connecting part 801 and a supporting part 802. The connecting part 801 is vertically bolted to the middle of the column 1, and the supporting part 802 is horizontally fixed to the top of the connecting part 801. The supporting part 802 forms a supporting structure so that one edge plate of the middle crossbeam 4 can be erected on the supporting part 802. Combined with the L-shaped structure of the middle crossbeam 4, it forms a pre-positioning effect. After the pre-positioning is completed, the edge plate of the middle crossbeam 4 is bolted to the supporting part 802.

[0021] like Figure 7 The column 1 includes an upper column 101 and a lower column 102. Both the upper column 101 and the lower column 102 are vertically spaced and have several adjustment holes 103. A connector 104 is inserted into the adjustment hole 103. The connector 104 is a bolt kit, which detachably connects the upper column 101 and the lower column 102 and can be adjusted up and down by changing different adjustment holes 103.

[0022] The bottom of column 1 is fixedly connected with anti-slip pad 9, which is made of 200mm×200mm×10mm steel pad to improve structural stability.

[0023] The construction process in this embodiment is as follows: (1) Waterproofing and protection of the subbase layer: pouring and curing of the subbase layer; (2) Place anti-slip mats 9 on the pad 10 according to the spacing of the columns 1; (3) After laying the bottom steel reinforcement 7 of the raft slab, install the column 1 according to the column spacing, and weld the column 1 firmly to the anti-slip pad 9; (4) Bolt the support member 8 in the middle of the column 1, and bolt the middle crossbeam 4 on the support member 8; (5) C25 steel bars are used to weld vertical bracing 2. The bracing 2 cross-connects the bottom and top of the column 1 with each other. All columns 1 need to be connected. (6) Install the middle reinforcement bars of the raft slab (5); (7) Weld the top beam 3 at the top of column 1 and finally install the top steel bar 6 of the raft slab.
