Description

Technical Field

[0001] The utility model relates to the technical field of mechanical energy storage, and particularly relates to a fully prefabricated steel-reinforced concrete structural member for mechanical energy storage. Background Technique

[0002] The mechanical energy storage structure is a super high-rise concrete structure with a height exceeding 150m. Its structural members have simple shapes and high standardization, which are in line with the advantages of prefabricated buildings and can adapt to the application scenarios of prefabricated construction.

[0003] The height of the mechanical energy storage structure breaks through the application height limit of the national technical standard for prefabricated concrete buildings. Limited by the current technology and specifications, the cast-in-place technology of reinforced concrete is still used in the construction process of mechanical energy storage projects. However, the cast-in-place technology cannot meet the construction process requirements of mechanical energy storage. At the same time, due to the large-scale lack of floor slabs inside the mechanical energy storage structure, the cast-in-place construction method lacks a construction operation surface and requires a large number of construction scaffolds to be erected, which is not conducive to the cost control of the mechanical energy storage structure. In addition, the size of the mechanical energy storage structure is too large, and the number of personnel required for the application of traditional cast-in-place technology is large, and the production cycle is long, which will affect the delivery progress of the mechanical energy storage structure. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the utility model provides a fully prefabricated steel-reinforced concrete structural member for mechanical energy storage, which solves the problems of complex structure and high installation difficulty at the connection node part in the existing cast-in-place technology, simplifies the construction and installation process of the mechanical energy storage structure, and speeds up the construction and delivery progress.

[0005] To achieve the above technical purpose, the utility model adopts the following technical scheme: A fully prefabricated steel-reinforced concrete structural member for mechanical energy storage is composed of a plurality of fully prefabricated steel-reinforced concrete structural units spliced in sequence. The fully prefabricated steel-reinforced concrete structural unit includes a fully prefabricated steel-reinforced concrete structural column arranged vertically, a fully prefabricated steel-reinforced concrete structural beam arranged horizontally, and a fully prefabricated floor slab. A beam-column connection node is formed between the fully prefabricated steel-reinforced concrete structural column and the fully prefabricated steel-reinforced concrete structural beam, and a fully prefabricated floor slab is arranged in the grid unit surrounded by the fully prefabricated steel-reinforced concrete structural column and the fully prefabricated steel-reinforced concrete structural beam; when the upper and lower layers of the fully prefabricated steel-reinforced concrete structural unit are spliced, a column-column connection node is formed between the upper and lower pairs of fully prefabricated steel-reinforced concrete structural columns.

[0006] Further, the fully prefabricated steel-reinforced concrete structural beam includes: steel plates, fully prefabricated steel beam gusset plates and webs. Two steel plates are arranged horizontally, and fully prefabricated steel beam gusset plates are arranged at equal intervals between the two steel plates to form a fully prefabricated steel beam skeleton, and one web is provided at each end of the fully prefabricated steel beam skeleton;

[0007] Concrete is poured on the above-mentioned fully prefabricated steel - framed beam skeleton to form a fully prefabricated steel - reinforced concrete structural beam, and the web is exposed from the fully prefabricated steel - reinforced concrete structural beam.

[0008] Furthermore, the steel plate and the batten plate of the fully prefabricated steel - framed beam are fixed by welding, and the web and the steel plate are fixed by welding.

[0009] Furthermore, the fully prefabricated steel - reinforced concrete structural column includes: the first fully prefabricated steel - framed column angle steel and the first fully prefabricated steel - framed column batten plate. The first fully prefabricated steel - framed column angle steel is arranged at the four corners, and the first fully prefabricated steel - framed column batten plates are arranged at equal intervals between adjacent first fully prefabricated steel - framed column angle steels;

[0010] Concrete is poured outside the rectangular fully prefabricated steel - framed column section steel skeleton formed by the first fully prefabricated steel - framed column angle steel and the first fully prefabricated steel - framed column batten plate to form a fully prefabricated steel - reinforced concrete structural column, and the interior of the fully prefabricated steel - reinforced concrete structural column is a hollow structure.

[0011] Furthermore, the first fully prefabricated steel - framed column angle steel and the first fully prefabricated steel - framed column batten plate are fixed by welding.

[0012] Furthermore, a section of the second fully prefabricated steel - framed column angle steel is arranged at the center of each first fully prefabricated steel - framed column batten plate, and the second fully prefabricated steel - framed column batten plates are arranged at equal intervals between adjacent second fully prefabricated steel - framed column angle steels.

[0013] Furthermore, the fully prefabricated steel - reinforced concrete structural column further includes: an I - beam. The I - beam extends out of the fully prefabricated steel - reinforced concrete structural column. The I - beam is fixedly connected to the web by bolts, and the upper and lower flange plates of the I - beam and the steel plate are fixed by welding to form a beam - column connection node.

[0014] Furthermore, in - plane diaphragms are respectively arranged on the upper and lower sides of the fully prefabricated steel - reinforced concrete structural column, and the setting range of the in - plane diaphragms is within the flange range of the I - beam.

[0015] Furthermore, the in - plane diaphragm is provided with weight - reducing openings, and the openings of the weight - reducing openings are aligned with the hollow structure.

[0016] Furthermore, the first fully prefabricated steel - framed column angle steels extending out of the fully prefabricated steel - reinforced concrete structural columns of the upper and lower layers in pairs are aligned and fixed to form a column - column connection node.

[0017] Compared with the prior art, the utility model has the following beneficial effects: The fully prefabricated steel-reinforced concrete structural member for mechanical energy storage of the utility model is different from the traditional mechanical energy storage member, and applies a new type of fully prefabricated assembly construction technology. The mechanical energy storage structure consists of a fully prefabricated steel-reinforced concrete structural beam, a fully prefabricated steel-reinforced concrete structural column, and a fully prefabricated floor slab to form a fully prefabricated steel-reinforced concrete structural unit. Through dry beam-column connection nodes and column-column connection nodes, they are spliced to form a fully prefabricated steel-reinforced concrete structural member, which simplifies the construction process of the mechanical energy storage structural member. Compared with the traditional prefabricated member connected by steel bar grouting, it has higher efficiency. At the same time, during the installation process, there is no need to set vertical supports for the members, which can reduce the construction difficulty and shorten the construction period. By using the fully prefabricated steel-reinforced concrete structural member for mechanical energy storage of the utility model, the weight of the fully prefabricated steel-reinforced concrete structural column is reduced through a hollow structure, making the overall member lighter and more convenient for installation. By filling with a slightly expanded high-strength concrete material later, the member has higher bearing capacity, ensuring the use safety of the mechanical energy storage structural member.

Detailed implementation manners

[0028] The technical solutions of the present utility model will be further explained and illustrated below in conjunction with the accompanying drawings.

[0029] As Figure 1 is a schematic diagram of a fully precast steel - reinforced concrete structural member for mechanical energy storage of the present utility model. The fully precast steel - reinforced concrete structural member for mechanical energy storage is a fully precast structural member with a concrete - wrapped steel - skeleton. It is composed of a number of fully precast steel - reinforced concrete structural units spliced in sequence. The fully precast steel - reinforced concrete structural unit includes a vertically arranged fully precast steel - reinforced concrete structural column 1, a horizontally arranged fully precast steel - reinforced concrete structural beam 2, and a fully precast floor slab 3. A beam - column connection node is formed between the fully precast steel - reinforced concrete structural column 1 and the fully precast steel - reinforced concrete structural beam 2, and a fully precast floor slab 3 is arranged in the grid unit surrounded by the fully precast steel - reinforced concrete structural column 1 and the fully precast steel - reinforced concrete structural beam 2; when the upper and lower layers of the fully precast steel - reinforced concrete structural unit are spliced, a column - column connection node is formed between the upper and lower pairs of fully precast steel - reinforced concrete structural columns 1. The present utility model constructs the fully precast steel - reinforced concrete structural unit through a new type of fully precast assembly construction technology, and splices the fully precast steel - reinforced concrete structural units through dry beam - column connection nodes and column - column connection nodes to form a fully precast steel - reinforced concrete structural member, realizing the non - support during the installation process of the fully precast steel - reinforced concrete structural member for mechanical energy storage, reducing the construction difficulty and shortening the construction period.

[0030] As Figures 2-3 , in the present utility model, the fully precast steel - reinforced concrete structural beam 2 includes: a steel plate 4, a fully precast steel - beam batten plate 5, and a web 6. Two steel plates 4 are horizontally arranged, equivalently replacing the longitudinal stressed steel bars of the reinforced concrete beam member, and fully precast steel - beam batten plates 5 are arranged at equal intervals between the two steel plates 4 to form a fully precast steel - beam skeleton. The fully precast steel - beam batten plate 5 is equivalently obtained from the stirrups in the reinforced concrete beam member. One web 6 is provided at each end of the fully precast steel - beam skeleton. Specifically, the steel plate 4 and the fully precast steel - beam batten plate 5 are fixed by welding, and the web 6 and the steel plate 4 are fixed by welding. Concrete is poured on the fully precast steel - beam skeleton to form the fully precast steel - reinforced concrete structural beam 2, and the web 6 protrudes from the fully precast steel - reinforced concrete structural beam 2. The web 6 is an important part for connecting the fully precast steel - reinforced concrete structural beam 2 and the fully precast steel - reinforced concrete structural column 1.

[0031] In the fully precast steel - reinforced concrete structural column 1, the area of the angle steel is obtained by strength equivalence from the area of the longitudinal steel bars in the reinforced concrete column, and the spacing and area of the batten plates are equivalently replaced according to the area of the stirrups in the reinforced concrete column. For example Figures 4-5 , in a technical solution of the present utility model, the fully precast steel - reinforced concrete structural column 1 includes: the first fully precast steel column angle steel 8 and the first fully precast steel column batten plate 10. The first fully precast steel column angle steel 8 is arranged at the four corners, and the first fully precast steel column batten plates 10 are arranged at equal intervals between adjacent first fully precast steel column angle steels 8. Specifically, the first fully precast steel column angle steel 8 and the first fully precast steel column batten plate 10 are fixed by welding. Concrete is poured outside the rectangular fully precast steel column steel skeleton formed by the first fully precast steel column angle steel 8 and the first fully precast steel column batten plate 10 to form the fully precast steel - reinforced concrete structural column 1.

[0032] For example Figure 9 , in another technical solution of the present utility model, when the strength requirements of the fully precast steel - reinforced concrete structural column 1 cannot be met only by the design of the first fully precast steel column angle steel 8 and the first fully precast steel column batten plate 10, a section of the second fully precast steel column angle steel 13 can be set at the center of each first fully precast steel column batten plate 10, and the second fully precast steel column batten plates 14 are arranged at equal intervals between adjacent second fully precast steel column angle steels 13 to further improve the strength of the fully precast steel - reinforced concrete structural column 1.

[0033] Among various structural components that make up the mechanical energy storage structure, the self - weight of the fully precast steel - reinforced concrete structural column 1 is much greater than that of other types of components. When selecting a hoisting device, large - tonnage hoisting equipment is used to meet the hoisting requirements of column components, which is not conducive to the control of construction costs. Therefore, the present utility model takes weight - reduction measures for the fully precast steel - reinforced concrete structural column 1, and sets the inside of the fully precast steel - reinforced concrete structural column 1 as a hollow structure 7 to reduce the self - weight of the fully precast steel - reinforced concrete structural column 1. The hollow structure 7 needs to be filled secondarily after the fully precast steel - reinforced concrete structural column 1 is in place and installed. Since there are problems of new - old concrete interface in the secondary filling process, micro - expanded high - strength concrete added with calcium - magnesium composite expansion agent is used as the filling material to offset the shrinkage strain during the hydration process of concrete and enhance the connection strength of the new - old concrete interface. At the same time, the hollow structure 7 adopts the process of embedding wires and roughening the surface to prevent the relative slip between the new and old concrete.

[0034] For example Figures 6-8, the fully precast steel reinforced concrete structural column 1 in the present utility model further includes: an I-beam 9, the I-beam 9 extends out of the fully precast steel reinforced concrete structural column 1, the height and dimensions of the I-beam 9 are consistent with the web of the corresponding fully precast steel reinforced concrete structural beam 2, the I-beam 9 is fixedly connected to the web 6 by bolts, and the upper and lower flange plates of the I-beam 9 are fixedly connected to the steel plate 4 by welding to form a beam-column connection node. Since this beam-column connection node is a dry process, it can simplify the construction process of mechanical energy storage structure components and improve construction efficiency.

[0035] As Figure 5 , 8 , plane diaphragms 11 are respectively arranged on the upper and lower sides of the fully precast steel reinforced concrete structural column 1. The arrangement range of the plane diaphragms 11 is within the flange range of the I-beam 9 to ensure that the column I-beam 9 forms a reliable connection with the fully precast steel reinforced concrete structural column 1 through the plane diaphragms 11. The plane diaphragms 11 are provided with weight-reducing openings 12, and the openings of the weight-reducing openings 12 are aligned with the hollow structure 7. When the hollow structure 7 needs to be filled, concrete can enter the hollow structure 7 in the fully precast steel reinforced concrete structural column 1 through the weight-reducing openings 12.

[0036] The first fully precast steel column angle steels 8 extending out of the fully precast steel reinforced concrete structural columns 1 in the upper and lower layers are aligned and fixed in pairs to form a column-column connection node. Specifically, the corresponding first fully precast steel column angle steels 8 are fixed by bolts and then formed into a whole by welding. This column-column connection node adopts a dry process, which can simplify the construction process of mechanical energy storage structure components and improve construction efficiency.

[0037] In a technical solution of the present utility model, the installation process of the fully prefabricated steel-reinforced concrete structural members for mechanical energy storage follows the rule of sequential hoisting. On each floor, the fully prefabricated steel-reinforced concrete structural column 1 is the structural member to be installed with the highest priority. There are four sections of the first fully prefabricated steel column angle steels 8 protruding from the concrete surface at the bottom of the fully prefabricated steel-reinforced concrete structural column 1 on the floor. During the positioning process, the positions of the four sections of the first fully prefabricated steel column angle steels 8 are aligned with the parts of the fully prefabricated steel-reinforced concrete structural column 1 protruding from the first fully prefabricated steel column angle steels 8 under the floor, and gaskets are placed before the fully prefabricated steel-reinforced concrete structural column 1 is completely positioned to avoid damage to the first fully prefabricated steel column angle steels 8 caused by the instantaneous impact force during positioning. After the fully prefabricated steel-reinforced concrete structural column 1 is positioned, the upper and lower layers of the first fully prefabricated steel column angle steels 8 are bolted in time, and no diagonal support for column members needs to be set throughout the process; after the positioning installation of the fully prefabricated steel-reinforced concrete structural column 1 is completed, secondary filling is carried out for the hollow structure 7, and then the fully prefabricated steel-reinforced concrete structural beam 2 is hoisted. During the installation process of the fully prefabricated steel-reinforced concrete structural beam 2, it hovers at the installation position, and the beam-column connection nodes are bolted, enabling support-free installation. The fully prefabricated steel-reinforced concrete structural members for mechanical energy storage of the present utility model no longer need to set vertical supports for the members during the installation process, which can reduce the construction difficulty and shorten the construction period.

[0038] The above is only the preferred implementation mode of the present utility model. The protection scope of the present utility model is not limited to the above implementation mode. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should be regarded as within the protection scope of the present utility model.
