Description

Technical Field

[0001] This utility model relates to the field of electronic chip factory construction, and in particular to a snap-fit ​​component pre-embedded in the waffle plate of an electronic chip factory. Background Technology

[0002] Waffle slabs are a type of formwork used in reinforced concrete cast-in-place grid beam floor slabs. In some electronic chip factories, cleanrooms are a crucial component. Due to process requirements, tens of thousands of pipelines need to run through the second and third floors. Numerous ventilation ducts, fire hydrants, and other pipes are installed beneath the ceilings on the second and third floors. Maintaining positive pressure within the cleanroom requires forcing clean air in, necessitating numerous holes in the floor slab between the second and third floors. Cylindrical waffle slabs are used to create these holes. Previously, the installation of ventilation and fire hydrants involved drilling holes in the concrete ceilings of the second and third floors after the waffle slabs were laid and the concrete had hardened. Fixing brackets were then secured to these holes with expansion bolts, and the ventilation and fire hydrants were fixed to the brackets. This installation method was extremely cumbersome, time-consuming, and labor-intensive, impacting construction efficiency. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a snap-fit ​​component that is simple in structure, convenient for installing ventilation pipes, fire pipes and other pipelines, and improves construction efficiency. It can be embedded in the waffle board of an electronic chip factory.

[0004] The technical solution of this utility model for a snap-fit ​​assembly pre-embedded in a waffle plate in an electronic chip factory is as follows: it includes a number of waffle plates and snap-fit ​​rails. Each waffle plate is arranged adjacent to each other in the front, back, left, and right directions. Snap-fit ​​rails are respectively arranged between adjacent waffle plates in the left and right directions. Each waffle plate includes a square base plate with four cylindrical bodies evenly distributed on the base plate. Through holes are opened in the cylindrical bodies. Upward flanges are provided around the perimeter of the base plate. Each snap-fit ​​rail includes a body. The side wall of the body contacts the flanged side wall of the waffle plate. A positioning structure is provided between the body and the flange. A through slot is opened in the body, and a nut is placed in the slot. A bottom opening is opened below the slot. Two or more fixing rivets are provided on the upper part of the body.

[0005] Furthermore, the positioning structure includes a positioning groove on the side wall of the flange and a positioning protrusion on the side wall of the main body, with the positioning groove and the positioning protrusion engaging in positioning.

[0006] Furthermore, the base plate is provided with cross-shaped dividing ribs, and rib grooves are formed in the dividing ribs.

[0007] Furthermore, a protruding positioning ring is provided on the outer wall of the cylinder.

[0008] The beneficial effects of this utility model of a snap-fit ​​assembly pre-embedded in a waffle plate in an electronic chip factory are: First, when laying waffle slabs, the rails are set together between the adjacent waffle slabs on the left and right sides. The installation is convenient and there is no need to drill holes or install expansion bolts in the solidified concrete later.

[0015] This utility model relates to a snap-fit ​​assembly pre-embedded in the waffle plate of an electronic chip factory, such as... Figure 1 — Figure 7As shown, the device includes a number of waffle plates 1 and guide rails 2. Each waffle plate 1 is arranged adjacent to each other in the front, back, left, and right directions. Guide rails 2 are respectively arranged between adjacent waffle plates 1. Each waffle plate 1 includes a square base plate 11. Four cylinders 12 are evenly distributed on the base plate 11. Through holes 13 are opened in the cylinders 12. Upward flanges 14 are provided around the base plate 11. Each guide rail 2 includes a body 21. The side wall of the body 21 contacts the side wall of the flange 14 of the waffle plate 1. A positioning structure is provided between the body 21 and the flange 14. A through groove 22 is opened in the body 21. A nut is placed in the groove 22. A lower opening 23 is opened below the groove 22. Two or more fixing rivets 24 are provided on the upper part of the body 21.

[0016] Furthermore, the positioning structure includes a positioning groove 15 on the side wall of the flange 14 and a positioning protrusion 25 on the side wall of the body 21, with the positioning groove 15 and the positioning protrusion 25 engaging in positioning cooperation. The positioning groove 15 and the positioning protrusion 25 ensure accurate positioning of the flange 14 and the body 21.

[0017] Furthermore, the base plate 11 is provided with cross-shaped dividing ribs 16, and rib grooves 17 are formed in the dividing ribs 16. With the dividing ribs 16 and the rib grooves 17, the base plate 11 can be divided according to the structure of the building.

After the division, the dividing ribs 16 also become the flanges on all four sides, ensuring the structural strength of the base plate 11.

[0018] Furthermore, a protruding positioning ring 18 is provided on the outer wall of the cylinder 12. During construction, concrete needs to be poured on the outer wall of the cylinder 12. After the concrete solidifies, the positioning ring 18 can position the cylinder 12, allowing the cylinder 12 to fit better with the concrete and preventing it from easily coming off.

[0019] This utility model discloses a snap-fit ​​assembly pre-embedded in a waffle board in an electronic chip factory. The main feature is that during the laying of the waffle boards 1, a snap-fit ​​rail 2 is installed between adjacent waffle boards 1 (the specific laying method of the waffle boards is existing technology; refer to paragraph 0026 of patent publication CN210530318U). The two sides of the body 21 of the snap-fit ​​rail 2 are respectively attached to the flanges 14 of two adjacent waffle boards 1. The attachment points can be bonded together with adhesives such as glue to seal the gaps. The height of the body 21 is the same as the height of the flanges 14. The body 21 and the flanges 14 are positioned and fitted together by a positioning structure. A through-groove groove 22 is opened in the body 21, and a number of nuts 31 are set in the groove 22. The nuts 31 can move back and forth along the groove 22 but cannot rotate. A lower opening 23 is provided at the bottom of the slot 22, and two or more fixing rivets 24 are provided at the top of the body 21. After the laying is completed, concrete 32 is poured on the outer wall of the cylinder 12 at the top of the base plate 11 and the body 21, so that the rail 2 is directly integrated with the concrete 32 as an embedded part. After the concrete 32 solidifies, it forms the floor slab between the second and third floors. The rail 2 is fixed to the concrete 32 by the fixing rivets 24 at the top, so that the rail 2 cannot be removed. When ventilation pipes, fire pipes and other pipelines 33 are to be laid below the floor slab (which is also the ceiling of the next floor), the fixing bracket 34 can be fixedly connected to the nut 31 by fasteners such as bolts 35 passing through the lower opening 23. The ventilation pipes, fire pipes and other pipelines 33 are fixed to the fixing bracket 34, so that the pipelines can be installed without drilling holes in the concrete, which is very convenient.
