[0002] With increasing government support for the semiconductor industry, the demand for high-precision electronic industrial plants is rising. These plants are characterized by tight deadlines, large investments, and stringent requirements for cleanliness and low vibration levels. Currently, most of these plants utilize cast-in-place concrete structures, which suffer from problems such as large formwork requirements, numerous high-formwork areas, and long construction cycles, failing to meet the requirements of industrialized construction. Therefore, there is an urgent need for a plant structure system that is convenient and fast to construct, thereby improving the level of industrialization in the construction of these plants while ensuring the cleanliness and low vibration requirements of high-precision electronic industrial plants. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a high-precision electronic industrial plant composite structure system, aiming to solve the problems of long construction cycle, high construction difficulty, and low level of building industrialization in existing high-precision electronic industrial plants using cast-in-place concrete structures.
[0004] This utility model proposes a high-precision electronic industrial plant composite structure system, comprising: steel-concrete composite columns, steel-concrete composite floor slabs, concrete waffle floor slabs, concrete columns, and steel trusses; multiple steel-concrete composite columns are arranged in an array, and the concrete waffle floor slabs are located on top of the steel-concrete composite columns; multiple concrete columns are arranged in an array on the concrete waffle floor slabs, and the steel trusses are located on top of the concrete columns; the steel-concrete composite floor slabs are located below the concrete waffle floor slabs, and the steel-concrete composite floor slabs include steel beams, slotted composite slabs, and post-cast layers; the steel beams are connected between the steel-concrete composite columns, the slotted composite slabs are laid on the steel beams, and the post-cast layers are laid on the upper ends of the steel beams and the slotted composite slabs and in the gaps.
[0005] Furthermore, the sidewall of the steel-concrete composite column is provided with an extended steel beam; the extended steel beam is connected to the steel beam of the steel-concrete composite floor slab through a connecting assembly.
[0006] Furthermore, the connecting assembly includes a connecting plate and high-strength bolts; the connecting plate is laid at the joint between the extended steel beam and the steel beam of the steel-concrete composite floor slab, and a portion of the high-strength bolts connect the extended steel beam and the connecting plate, while another portion connects the steel beam of the steel-concrete composite floor slab and the connecting plate.
[0007] Furthermore, the inner wall of the steel-concrete composite column is provided with reinforcing ribs and reinforcing nails at the positions where the extended steel beams are located.
[0008] Furthermore, the grooved composite slab has a groove on its edge, and the steel-concrete composite floor slab also includes additional reinforcing bars, which are placed inside the groove.

[0012] The beneficial effects of this utility model are as follows: The structural system of this utility model considers the combined characteristics of steel-concrete composite columns and steel-concrete composite floor slabs. The effective combination of floor slabs and steel beams can improve the overall rigidity of the floor slabs and fully utilize the material properties of steel (suitable for tension) and concrete (suitable for compression). Compared with the cast-in-place concrete structures commonly used in high-precision electronic industrial plants, steel beams can provide natural support for the concrete slabs. When used in conjunction with precast concrete slotted composite slabs, no additional formwork is required, greatly reducing the amount of formwork work and increasing construction speed.

Compared with pure steel structures, the composite structure of this utility model reduces the amount of steel used, lowers costs, and simultaneously improves the overall rigidity and comfort of the structure. The composite structure of steel-concrete composite columns and composite floor slabs has certain advantages in improving construction speed, reducing construction difficulty, and improving overall economy, while meeting the cleanliness and micro-vibration requirements of high-precision electronic industrial plants.

Detailed Implementation
[0020] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0021] like Figure 1 As shown, the existing high-precision electronics industrial plant has four floors, including: a second-floor slab, a third-floor slab, a lower chord of the truss, and an upper chord of the truss (roof). In common cast-in-place concrete schemes, the roof and the lower chord of the truss use a profiled steel sheet floor structure, which has high construction efficiency; the third-floor slab is a lattice beam / wafer slab, which creates unobstructed airflow to ensure cleanliness, but the structure is relatively complex, requiring high construction precision and high resistance to micro-vibration, making it relatively unsuitable for prefabricated design. Compared with the traditional cast-in-place concrete structure of high-precision electronics industrial plants, the composite structure system of this embodiment is designed for prefabricated construction of the first and second floors, which have no micro-vibration requirements. The plant structure is regular, with uniform column and beam spacing. Based on the original scheme, the first and second floors are optimized into a composite frame structure of steel tube concrete columns + steel beams + composite slabs.
[0022] like Figure 2 As shown, the high-precision electronic industrial plant composite structure system of this embodiment consists of steel-concrete composite columns 1, steel-concrete composite floor slabs 2, concrete waffle floor slabs 3, concrete columns 4, and steel trusses 5. In this high-precision electronic industrial plant composite structure system, the first and second floor columns are steel-concrete composite columns 1, the second floor floor slab is a steel-concrete composite floor slab 2, the third-floor clean production area uses a concrete waffle floor slab 3, the third-floor columns are concrete columns 4, and the top floor uses steel trusses 5.
[0023] like Figure 5 , 6As shown, the side of the steel-concrete composite column 1 extends outward from the steel beam 10, which is connected to the steel beam 2-1 in the composite floor system 2 via high-strength bolts 6 and connecting plates 7. The beam-column connection node adopts a bolted-welded hybrid form to achieve a rigid connection. The steel-concrete composite column 1 is a square steel-concrete composite column, which itself provides a concrete pouring formwork and facilitates connection with the steel beam, thereby accelerating construction speed and ensuring connection quality. Reinforcing ribs and reinforcing nails are set inside the steel-concrete composite column 1 at positions corresponding to the outward steel beam 10. After concrete is poured into the steel-concrete composite column 1, the reinforcing ribs and reinforcing nails are encased in concrete, increasing the rigidity of the steel-concrete composite column 1.
[0024] like Figure 3 , 4 As shown, the steel-concrete composite floor slab 2 consists of steel beams 2-1, slotted composite slabs 2-2, and a post-cast layer 2-3. Studs 8 are installed on the steel beams 2-1. The slotted composite slab 2-2 has slots on all four sides and is a precast slab. After the precast slabs are installed, additional reinforcing bars 9 are placed in the slots of the slotted composite slab 2-2. By adjusting the length of the slots, the anchorage length of the additional reinforcing bars 9 can be controlled, ensuring reliable force transfer between adjacent precast slabs. The post-cast layer 2-3 is then poured into the spaces between the precast slabs, forming the steel-concrete composite floor slab 2 as a whole. Both the steel beams 2-1 and the slotted composite slabs 2-2 are prefabricated in the factory and assembled on site. In this embodiment, the slotted composite slab eliminates truss reinforcement and outward-extending reinforcement, resulting in higher stacking efficiency and easier installation. During construction, steel beam 2-1 is first connected to steel-concrete composite column 1, and then slotted composite slab 2-2 is placed on steel beam 2-1 without the need for additional temporary supports. The post-cast layer 2-3 can be directly poured on the transverse support system composed of steel beam 2-1 and composite slab 2-2 without the need for additional formwork, reducing the amount of formwork and on-site concrete pouring, and speeding up the construction process.
[0025] like Figure 2 As shown, the concrete waffle floor slab 3 is a cast-in-place porous concrete structure that meets the requirements of a cleanroom. The steel truss 5 is the equipment floor of the building. A concrete slab is installed on the upper chord of the truss to form the roof, and a partial concrete slab is installed on the lower chord of the truss to house mechanical and electrical equipment.
[0026] The construction method of the high-precision electronic industrial plant combined structure system in this embodiment includes the following steps:
[0027] Step 1: Pre-fabricate the steel-concrete composite column 1, steel beams 2-1 and slotted composite slabs 2-2 in the steel-concrete composite floor slab 2, and the studs 8, high-strength bolts 6, connecting plates 7 and steel trusses 5 in the steel beam 2-1 according to the design dimensions in the factory. During the fabrication of the steel-concrete composite column, a section of extended steel beam 10 is welded in the factory, and bolt holes are pre-drilled. After transportation to the site, measure and position the steel-concrete composite column 1, and pour the internal concrete of the steel-concrete composite column 1.
[0028] Step Two: Connect steel beam 2-1 to the extended steel beam 10 of the steel-concrete composite column 1 to form a frame system. High-strength bolts 6 are used to connect steel beam 2-1 and the extended steel beam 10, avoiding on-site welding, accelerating construction speed, reducing construction difficulty, and improving construction quality. During on-site construction, double-sided connecting plates 7 are used to connect the flanges and webs of the two steel beams (steel beam 2-1 and extended steel beam 10) to achieve a rigid connection. The width of the connecting plate 7 on the upper flange should be less than the beam width to ensure smooth laying of the slotted composite slab 2-2. Internal end plates (i.e., reinforcing ribs) and studs (i.e., reinforcing nails) are installed in the joint area of the steel-concrete composite column 1 to ensure that the steel-concrete composite column 1 and the internal concrete do not separate due to the load transmitted by the steel beams.
[0029] Step 3: Determine the dimensions of the slotted composite slab 2-2 according to the steel beam layout plan. The thickness of the slotted composite slab 2-2 should be sufficient to withstand the wet weight load of the post-cast layer during construction and the self-weight load during hoisting. Lay the slotted composite slab 2-2 on the steel beam 2-1, and place additional reinforcing bars 9 in the slots. A new type of slotted connection joint structure without reinforcing bars is adopted. Rectangular slots are opened on the sides of the precast slab (i.e., the slotted composite slab 2-2). After the precast slab is installed in place, additional reinforcing bars 9 are placed in the slots. The anchorage length of the additional reinforcing bars 9 can be controlled by reasonably adjusting the length of the slots, ensuring reliable force transmission between adjacent precast slabs. Compared with traditional steel truss composite slabs, the new composite slab eliminates the truss reinforcing bars and outward reinforcing bars, resulting in higher stacking efficiency and easier installation. The elimination of truss reinforcing bars has almost no impact on the mechanical properties of the composite slab, and the close-fitting joint structure of the composite slab does not affect the load-bearing performance of the composite slab.
[0030] Step 4: Pour the post-cast concrete layer 2-3. Studs 8 are placed on the upper flange of steel beam 2-1, and the upper layer of reinforcing mesh is placed on top of the slotted composite slab 2-2. The post-cast layer is then poured to form a monolithic structure. During the construction of the two-story steel-concrete composite floor slab 2, the steel beams and the composite concrete slab can be used as supports, eliminating the need for full-span scaffolding, reducing formwork work, and accelerating construction speed.
[0031] Step 5: Construction of the clean production layer and truss layer. High-precision electronic industrial plants achieve cleanliness requirements through air circulation: air is regulated for temperature and humidity to meet cleanroom conditions, then enters the cleanroom work area through a filtration system installed in the truss layer. The air descends through the floor slab, then through the lower mezzanine into the return air duct, forming a circulation. To ensure smooth airflow, the work area floor slab must employ a porous structure similar to lattice beams or waffle slabs, combined with a raised floor. High vibration damping requirements make prefabricated design relatively difficult; therefore, traditional construction methods are used. The truss layer uses a steel structure, offering higher construction efficiency; traditional construction methods are also employed.
[0032] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
