Description

Technical Field

[0001] The present invention relates to the technical field of assembled flooring, and in particular to an assembled overhead floor with limited top support and foam filling. Background Art

[0002] Prefabricated floor systems refer to integrated floor systems that are primarily produced in factories using dry methods and assembled and installed on-site. They consist of an overhead adjustable support structure and a surface layer. Currently, the overhead floor products on the market all have certain overhead cavities, resulting in a hollow feeling that leads to a poor walking experience. During later use, the overhead products are prone to collapse, resulting in a high frequency of maintenance. In the overhead floor systems on the market, the overhead anchor components all support the bearing plate by placing the anchors on the floor and lifting them upward. This type of construction lacks a connection between the overhead floor product and the floor, which can easily cause large-scale warping and disturbance of the overhead floor structure, resulting in a poor walking experience. In severe cases, it can even cause cracks in the surface tiles. Therefore, a solution is urgently needed.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example See also Figure 1-5 As shown: The present invention provides an assembled elevated floor with limited top support and foam filling, comprising: a floor slab 10, a prefabricated balancing plate 20, a ground paving base layer 30 and a supporting and positioning assembly.

[0020] In specific applications, the ground paving base layer 30 constitutes the floor of an elevated floor for walking or placing objects; the prefabricated balancing plate 20 is installed on the floor slab 10 of the elevated floor to support the ground paving base layer 30; the two ends of the supporting and positioning assembly are respectively connected to the floor slab 10 and the prefabricated balancing plate 20 to fix and support the prefabricated balancing plate 20, and the supporting and positioning assembly fills the gap between the floor slab 10 and the prefabricated balancing plate 20.

[0021] Through such a setting, not only can the prefabricated balancing plate 20 be fixed on the floor 10, but the gap between the floor 10 and the prefabricated balancing plate 20 can also be filled, thereby preventing the prefabricated balancing plate 20 from loosening, bulging and warping, thereby providing stable support for the ground paving base 30, avoiding damage to the connecting layer 32 and tiles 31 of the ground paving base 30, and reducing the later maintenance cost of the assembled elevated floor.

[0022] Also included are pre-laid pipelines 50, which are used to install electrical wires or form water pipes 331. By placing the pre-laid pipelines 50 between the floor slab 10 and the prefabricated balancing plate 20, the pre-laid pipelines 50 are encased in the support and positioning assembly, allowing them to be stably fixed without displacement, thereby improving the stability of the pre-laid pipelines 50 during use.

[0023] It also includes a floor heating layer 33 ; the floor heating layer 33 is arranged between the ground paving base layer 30 and the prefabricated balancing plate 20 , and is used to provide heat to the ground paving base layer 30 .

[0024] The supporting and positioning assembly mainly consists of a fixing portion and a foaming rotor 44 .

[0025] In practical applications, the fixing portion can secure the prefabricated balancing plate 20 to the floor slab 10 and provide support for the prefabricated balancing plate 20, thereby preventing displacement and providing stable support. A foam rotor 44 is provided at the bottom of the prefabricated balancing plate 20 and contains a foam filler that fills the gap between the floor slab 10 and the prefabricated balancing plate 20.

[0026] The fixing portion includes a rivet nut screw 41 for connecting the prefabricated balancing plate 20 and the floor slab 10 and an expansion screw 43 for supporting the prefabricated balancing plate 20 .

[0027] The rivet nut screw 41 includes an expansion plug 411 , a self-tapping screw 412 and a fixing washer 413 .

[0028] In specific application, the operator first installs the expansion plug 411 in the floor slab 10, then passes the bottom end of the self-tapping screw 412 through the prefabricated balance plate 20 and connects it to the expansion plug 411, and the top end of the self-tapping screw 412 is clamped with the fixing gasket 413.

[0029] The expansion screw 43 includes a screw rod 431 , a rivet nut 432 and a support washer 433 .

[0030] In practical applications, the top end of the screw rod 431 is threadedly connected to the rivet nut 432, and the bottom end of the screw rod 431 abuts the upper surface of the floor slab 10. The rivet nut 432 is externally threaded and threadedly connected to the bottom surface of the prefabricated balancing plate 20. The support washer 433 is mounted on the rivet nut 432 and is in close contact with the bottom surface of the prefabricated balancing plate 20.

[0031] It also includes a second expansion screw 42; the second expansion screw 42 has the same structure as the expansion screw 43, and its length is shorter than that of the expansion screw 43, so that during the actual installation, the top of the second expansion screw 42 can be threadedly connected to the bottom surface of the prefabricated balancing plate 20, and the bottom end can abut against the upper surface of the pre-laid pipeline 50, so that a support point can be formed between the prefabricated balancing plate 20 and the pre-laid pipeline 50, thereby improving the stability of the support of the prefabricated balancing plate 20.

[0032] This arrangement allows the prefabricated balancing plate 20 to be fixed to the floor slab 10, forming a stable support at the bottom of the prefabricated balancing plate 20. Since the top ends of the self-tapping screws 412 engage the fixing washers 413, a pressing force is applied to the upper surface of the prefabricated balancing plate 20. This prevents the prefabricated balancing plate 20 from bulging when the foam filler fills the gap between the prefabricated balancing plate 20 and the floor slab 10, thereby ensuring the flatness of the prefabricated balancing plate 20. Furthermore, the foam filler fills the gap between the prefabricated balancing plate 20 and the floor slab 10 more evenly due to the restriction of the self-tapping screws 412.

[0033] The foaming rotor 44 includes a storage box 441, a foaming raw material package 442, a cover plate 443 and a rotating shaft 444; the cover plate 443 is snap-fitted to the opening of the storage box 441 and is fitted and connected to the bottom surface of the prefabricated balancing plate 20; the foaming raw material package 442 is installed in the storage box 441; the bottom of the rotating shaft 444 is connected to the rotating shaft at the bottom of the storage box 441 for limited rotation, and the top passes through the through hole on the cover plate 443, and the top of the rotating shaft 444 is provided with a hexagonal nut hole for rotating the rotating shaft, and the side of the rotating shaft 444 is provided with a rotating shaft blade 445 for piercing the foaming raw material package 442; the prefabricated balancing plate 20 is provided with an operating hole connected to the hexagonal nut hole of the rotating shaft 444.

[0034] In specific applications, a tool that can rotate the rotating shaft 444 is inserted along the operating hole, and the rotating shaft 444 is rotated so that the rotating shaft blade 445 cuts through the packaging bag of the foaming raw material package 442. There are at least two foaming raw material packages 442 in the storage box 441, and the raw materials in the damaged foaming raw material package 442 are mixed and react with each other to form foam 60 whose volume automatically expands. The expanded foam 60 releases the clamping force between the cover plate 443 and the storage box 441, so that the foam 60 can automatically fill the gap between the prefabricated balance plate 20 and the floor slab 10, and support the bottom surface of the prefabricated balance plate 20 after solidification.

[0035] Through such a setting, not only can the prefabricated elevated floor have better support and higher stability in use, but it is also easy to operate and has broad market application prospects.
