Multiple support members are arranged along the second direction D between the horizontal support member and the cast-in-place concrete floor slab, with both ends of the support members abutting against the horizontal support member and the cast-in-place concrete floor slab respectively. The support frame provides support for the cast-in-place concrete floor slab, the horizontal support member provides support for the support frame, and the vertical support member provides support for the horizontal support member. This establishes a force transmission path between the cast-in-place concrete floor slab and the equipment room.

[0036] Figure 1 The diagram shown is a structural schematic of a support structure for the top floor slab of pre-installed equipment provided in an embodiment of this application. Figure 2 The diagram shown is a partial structural schematic of the support unit in an embodiment of this application.

[0037] Please refer to Figures 1 to 2 This application provides a support structure for the top floor slab of a pre-installed device, used to support the pre-installed device 01. The pre-installed device 01 is located in an equipment room 02 and extends along a first direction D1 on the horizontal plane. The top of the equipment room 02 is provided with a cast-in-place concrete floor slab 03. Specifically, the construction of the top cast-in-place concrete floor slab 03 is carried out after the pre-installed device 01 is installed. The support structure includes multiple support units 100 arranged along the first direction D1, and adjacent support units 100 are interconnected. Each support unit 100 includes a support frame 110, a horizontal support member 120, and two vertical support members 130. 30 are respectively set on both sides of the second direction D2 of the pre-installed equipment 01. The horizontal support 120 is located above the pre-installed equipment 01. The bottom of the vertical support 130 is fixedly connected to the bottom plate of the equipment room 02, and the top of the vertical support 130 is fixedly connected to the horizontal support 120. The second direction D2 is parallel to the horizontal plane and perpendicular to the first direction D1. In each support unit 100, the support frame 110 includes multiple support members 111. The multiple support members 111 are arranged along the second direction D2 between the horizontal support 120 and the cast-in-place concrete floor slab 03, and the two ends of the support members 111 abut against the horizontal support 120 and the cast-in-place concrete floor slab 03, respectively.

[0038] In this embodiment, the support structure includes multiple support units 100 arranged along the first direction D1. Each support unit 100 includes a receiving frame 110, a horizontal support member 120, and two vertical support members 130. The two vertical support members 130 are respectively disposed on both sides of the pre-assembly equipment 01 in the second direction D2. The horizontal support member 120 is located above the pre-assembly equipment 01. The horizontal support member 120 and the two vertical support members 130 of each support unit 100 can respectively surround the pre-assembly equipment 01 from above and to the side. The multiple support units 100 can surround the entire pre-assembly equipment 01. Furthermore, in each support unit 100, the receiving frame 110 includes multiple supporting rods 111. Multiple support members 111 are arranged along the second direction D2 between the horizontal support member 120 and the cast-in-place concrete floor slab 03, and the two ends of the support members 111 abut against the horizontal support member 120 and the cast-in-place concrete floor slab 03 respectively. The support frame 110 provides support for the cast-in-place concrete floor slab 03, the horizontal support member 120 provides support for the support frame 110, and the vertical support member 130 provides support for the horizontal support member 120. Thus, a force transmission path is established between the cast-in-place concrete floor slab 03 and the equipment room 02. At the same time, the pre-installed equipment 01 enclosed in the support unit 100 will not be subjected to other external forces such as the cast-in-place concrete floor slab 03, protecting the pre-installed equipment 01 and ensuring that the pre-installed equipment 01 can work normally. In each support unit, the bottom of the vertical support member 130 is fixedly connected to the bottom plate of the equipment room 02, the top of the vertical support member 130 is fixedly connected to the horizontal support member 120, and the two ends of the support member 111 of the support frame 110 abut against the horizontal support member 120 and the cast-in-place concrete floor slab 03. Each support unit 100 is reliably and stably connected to the wall of the equipment room 02. The vertical support member 130, the horizontal support member 120 and the support frame 110 of each support unit 100 constitute a reliable and stable structure. In addition, two adjacent support units 100 are interconnected. Thus, multiple support units 100 together become a connecting structure, establishing a complete and reliable support structure between the equipment room 02 and the cast-in-place concrete floor slab 03.

[0039] In summary, the support structure provided in this embodiment provides strong and reliable support for the cast-in-place concrete floor slab 03. Its structural connection is reliable and its stability is high. Furthermore, the support structure is simple in structure and has few parts, which reduces the need for a large construction space. The construction process is simple and the cycle is short. There is no direct connection or contact between the support structure and the pre-installed equipment 01, which reduces the occurrence of contact with the equipment during construction and dismantling and reduces the occurrence of damage to the pre-installed equipment.

[0040] Figure 3 The diagram shown is a three-dimensional structural schematic of the longitudinal beam assembly in an embodiment of this application. See also... Figure 2In some embodiments, the vertical support member 130 includes an upper end plate 131, a longitudinal beam assembly 132 and a lower end plate 133 that are fixedly connected from top to bottom. The lower end plate 133 is connected to the bottom plate of the equipment room 02 by expansion bolts 135, and the surface of the upper end plate 131 is fixedly connected to the horizontal support member 120.

[0041] For specific implementation, please refer to Figure 3 The vertical support member 130 may include multiple vertical sub-support members arranged in a vertical direction. Each vertical sub-support member includes a top plate, a sub-longitudinal beam, and a bottom plate arranged sequentially from top to bottom. The top plate of the uppermost vertical sub-support member serves as the upper end plate 131 of the vertical support member 130, and the bottom plate of the lowermost vertical support member serves as the lower end plate 133 of the vertical support member 130. The bottom plates of the remaining vertical support members are fixedly connected to the top plates of their adjacent vertical support members. Multiple vertically arranged vertical support members are interconnected to jointly constitute the vertical support member 130. The advantage of this design is that it facilitates the assembly and disassembly of the vertical support member 130, avoiding difficulties in assembly or disassembly due to excessively large vertical dimensions.

[0042] In this embodiment, the lower end plate 133 is connected to the bottom plate of the equipment room 02 by expansion bolts 135, realizing a fixed connection between the vertical support member 130 and the bottom plate of the equipment room 02. This connection method is reliable. The plate surface of the upper end plate 131 is fixedly connected to the horizontal support member 120, realizing a fixed connection between the vertical support member 130 and the horizontal support member 120. In particular, because the contact area between the plate surface of the upper end plate 131 and the horizontal support member 120 is large, the connection reliability between the vertical support member 130 and the horizontal support member 120 is improved.

[0043] See Figure 2 and Figure 3 In some embodiments, both the upper end plate 131 and the lower end plate 133 are rectangular plate structures. The longitudinal beam assembly 132 includes four sub-longitudinal bars 1321 perpendicular to the horizontal plane, distributed at the four corners of the upper end plate 131 and the lower end plate 133. Such a longitudinal beam assembly 132 has high structural strength and low weight, thus the vertical support member 130 can reduce weight while ensuring structural strength, which is beneficial for the handling, assembly, and disassembly of the support structure. Furthermore, it can prevent the support structure from colliding with the equipment during assembly and disassembly, thus avoiding damage to the equipment. The vertical support member 130 also includes a reinforcing plate 134, which is located at the middle of the longitudinal beam assembly 132 in the vertical direction. The reinforcing plate 134 is fixedly connected to the four sub-longitudinal bars 1321. The reinforcing plate 134 improves the structural strength and bending resistance of the longitudinal beam assembly 132, thereby improving the structural performance of the longitudinal beam assembly 132.

[0044] Figure 4 The diagram shown is a schematic representation of the assembly structure of the assembly component and the sub-longitudinal rod in an embodiment of this application. See also... Figures 2 to 4 In some embodiments, along the second direction D2, a connecting rod 136 is provided between the sub-vertical rods 1321 of the two vertical support members 130 located on the same side of the pre-installed equipment 01. Both ends of the connecting rod 136 are connected by an assembly assembly. The assembly assembly includes a socket plate 141, an end plug 142, and a pin 143. The socket plate 141 has a central through hole 1412 and multiple connecting through holes 1411. The multiple connecting through holes 1411 are distributed circumferentially on the surface of the socket plate 141. The socket plate 141 is sleeved on the outer circumferential surface of the sub-vertical rod 1321 through the central through hole 1412. The end plug 142 is connected to the end of the connecting rod 136. The end plug 142 has an assembly through hole. The pin 143 passes through the assembly through hole and the connecting through hole 1411.

[0045] In this embodiment, the sub-longitudinal rods 1321 of two vertical support members 130 located on the same side of the pre-assembled equipment 01 can be connected through the assembly component and the connecting rod 136, thereby enabling the interconnection between two adjacent support units 100. The assembly component allows for a detachable connection between the connecting rod 136 and the sub-longitudinal rod 1321, making assembly and disassembly convenient and quick, which improves the assembly efficiency of the support structure and shortens the construction and disassembly cycle time.

[0046] See Figures 2 to 4 In some embodiments, the connecting rod 136 includes a first connecting rod 1361, which is parallel to the first direction D1, and its end is fixedly connected to the end plug 142. Thus, through the first connecting rod 1361, a fixed spacing can be maintained between the longitudinal beam assemblies 132 of the two vertical support members 130 located on the same side of the pre-installed equipment 01, which is beneficial to the connection stability between the two support units 100.

[0047] In some embodiments, the connecting rod 136 further includes a second connecting rod 1362, which is inclined in the horizontal direction and has its end hinged to the end plug 142. This further enhances the connection stability between the longitudinal beam assemblies 132 of the two vertical support members 130 located on the same side of the pre-installed equipment 01.

[0048] Figure 5The diagram shows a three-dimensional structural schematic of the horizontal support member in an embodiment of this application. In some embodiments, the horizontal support member 120 includes a beam body 121 and two connecting plates 122. The beam body 121 is an I-beam, and the two connecting plates 122 are fixedly connected to the bottom surfaces of both ends of the beam body 121. The surface of the connecting plates 122 is fixedly connected to the surface of the upper end plate 131. Thus, the connecting plates 122 and the upper end plate 131 are connected by a surface-to-surface contact method, resulting in high connection reliability and further improving the connection reliability between the horizontal support member 120 and the vertical support member 130. Furthermore, the contact area between the support member 111 and the horizontal support member 120 is relatively large, improving the connection reliability between the horizontal support member 120 and the support frame 110.

[0049] In practice, both the surface of the connecting plate 122 and the surface of the upper end plate 131 are provided with through holes. By passing bolts through the through holes in the surface of the connecting plate 122 and the upper end plate 131, a fixed connection between the horizontal support member 120 and the vertical support member 130 is achieved.

[0050] See Figure 1 In some embodiments, the support frame 110 further includes a support beam 112, which extends along the second direction D2 and is fixedly connected to all the support members 111. This achieves interconnection between all the support members 111, improving the structural strength of the support frame 110.

[0051] See Figure 1 In some embodiments, the receiving frame 110 further includes a supporting side frame 113. Along the second direction D2, the supporting side frame 113 is disposed between the vertical support member 130 and the side wall of the equipment room 02. The supporting side frame 113 is fixedly connected to the side wall of the equipment room 02 and the vertical support member 130 on both sides of the second direction D2, respectively. The top of the supporting side frame 113 is fixedly connected to the supporting beam 112, and the bottom of the supporting side frame 113 is fixedly connected to the bottom plate of the equipment room 02. In this embodiment, the supporting side frame 113 achieves a fixed connection between the receiving frame 110 and the equipment room 02. The force acting on the receiving frame 110 and the vertical support member 130 can be distributed to the side wall and bottom wall of the equipment room 02 through the supporting side frame 113, thereby improving the compressive strength of the support structure.
