Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shipyard ground treatment, in particular to an enhanced heavy-load floor. Background Art
[0002] In shipyards and heavy industry, due to the needs of production, manufacturing and storage, all factory floors are usually paved with concrete to facilitate operations such as workpiece manufacturing and vehicle transportation.
[0003] In traditional concrete floor construction, steel mesh is often used internally to reinforce the concrete structure. Since the floor layer is typically around 20cm thick and the steel mesh is typically small, the overall concrete strength is not significantly improved. Furthermore, when the surface concrete is impacted, scraped, and collided with workpieces, it can develop varying degrees of pitting, wear, and even cracking, significantly impacting workpiece manufacturing and vehicle transportation stability.
[0004] When workpieces or vehicles frequently operate in the same area, friction with the concrete will shorten the floor's service life. Furthermore, increased friction due to uneven surfaces can further exacerbate floor wear. To avoid this, the conventional method is to lay steel plates across the entire floor. While this significantly improves the floor's performance and wear resistance, the overall investment cost is too high to be practical for large-scale use. Furthermore, steel plates tend to deform over time, leading to overall stability issues and compromising workpiece manufacturing and vehicle transportation. Utility Model Content
[0005] In order to solve the problem that the existing heavy-duty floor does not improve the surface strength of concrete, and the concrete surface is still easily pitted, worn, or even cracked under the action of impact, scratching, etc., this utility model proposes an enhanced heavy-duty floor. The technical solution adopted is as follows:
[0006] A reinforced heavy-load floor, comprising a steel mesh layer disposed at the bottom of a concrete layer, and a reinforced mesh layer disposed at the top of the concrete layer, wherein the upper surface of the reinforced mesh layer is horizontal;
[0007] The enhanced grid layer comprises:
[0008] A plurality of first ribs are arranged side by side;
[0009] A plurality of second ribs are also arranged side by side, and the second ribs are perpendicular to the first ribs;
[0010] A first positioning groove is formed on the lower half of the first rib plate, a second positioning groove is formed on the upper half of the second rib plate, and the first rib plate and the second rib plate are spliced to each other through the first positioning groove and the second positioning groove.
[0011] In particular, a first transverse plate is provided on the top of the first rib plate, and a second transverse plate is provided on the top of the second rib plate; a plurality of limiting grooves are opened on the first transverse plate, and each limiting groove corresponds to the overlapping part of each first transverse plate and the second transverse plate.
[0012] In particular, the steel mesh layer covers the entire heavy-load floor projection range, and a plurality of reinforced mesh layers are evenly distributed within the heavy-load floor projection range.
[0013] In particular, a concrete buffer layer is provided above the reinforced grid layer.
[0014] Particularly, the reinforcement mesh layer is fixedly connected to the steel mesh layer via connecting ribs.
[0015] Compared with existing technologies, this new invention offers the following advantages and benefits: By installing a horizontal reinforced mesh layer on the top concrete layer, it provides sufficient support for the upper concrete layer and prevents further floor subsidence caused by heavy loads after the surface concrete layer is worn. This effectively controls the occurrence of pits and wear in the floor, improving the overall strength of heavy-load floors. Furthermore, it can replace the construction method of laying steel plates on the floor surface, effectively reducing construction costs and achieving high economic benefits.

DETAILED DESCRIPTION
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0022] like Figure 1 and Figure 2 As shown, a reinforced heavy-load floor comprises a steel mesh layer 2 arranged at the bottom of a concrete layer 1, and further comprises a reinforced mesh layer 3 arranged at the top of the concrete layer 1, wherein the upper surface of the reinforced mesh layer 3 is horizontal;
[0023] The enhanced grid layer 3 includes:
[0024] A plurality of first ribs 4 are arranged side by side;
[0025] A plurality of second ribs 5 are also arranged side by side, and the second ribs 5 and the first ribs 4 are perpendicular to each other;
[0026] A first positioning groove 6 is formed on the lower half of the first rib 4 , and a second positioning groove 7 is formed on the upper half of the second rib 5 . The first rib 4 and the second rib 5 are connected to each other through the first positioning groove 6 and the second positioning groove 7 .
[0027] In this utility model, the main principle is as follows: before pouring the heavy-duty floor, the steel mesh of the second layer is first tied and welded. The hole size of the conventional steel mesh is 200mm*200mm. The steel bars are 16 or 12mm in diameter, and the coating repair work is done on the outside of the tied steel mesh. Then the steel mesh is laid within the heavy-duty floor and initially poured. The pouring thickness is enough to cover all the steel mesh after vibration. During this process, the poured concrete needs to be fully vibrated, and after pouring, it needs to be cured to avoid concrete cracking. After the poured concrete has gained strength, the reinforced mesh layer 3 is laid out after roughening the hardened and solidified initial concrete. Specifically, the first and second locating grooves 6 and 7 are positioned relative to each other, and the first and second locating plates 4 and 5 are spliced into a grid pattern perpendicular to each other. They are then fixed to the hardened and solidified initial concrete. The fixing method can be to fix them to the concrete formwork by tensioning or to pre-embed positioning bars in the initial concrete. The secondary concrete pour is then carried out. The thickness of the secondary concrete pour is slightly greater than the height of the first and second locating plates 4 and 5, ensuring that the concrete layer can completely cover the first and second locating plates 4 and 5 after vibration. This effectively provides auxiliary support for the secondary concrete pour through the first and second locating plates 4 and 5, while effectively preventing large-scale pits or deformations in the heavy-loaded floor.
[0028] As a preferred embodiment, a first transverse plate is provided on the top of the first rib 4, and a second transverse plate is provided on the top of the second rib 5; a plurality of limiting grooves 8 are opened on the first transverse plate, and each limiting groove 8 corresponds one-to-one to the overlapping part of each first transverse plate and the second transverse plate.
[0029] In this embodiment, an optimized structure of the first rib plate 4 and the second rib plate 5 is provided, such as Figure 3 and Figure 4 As shown, specifically, by setting the first horizontal plate and the second horizontal plate on the top of the first rib plate 4 and the second rib plate 5 respectively, the form of the force bearing plate for bearing is formed, so that the heavy load above is supported by the first horizontal plate and the second horizontal plate, and the stress is transmitted to the concrete layer below by the first horizontal plate and the second horizontal plate, thereby dispersing and absorbing the heavy load, on the one hand, the stress area of the top of the first rib plate 4 and the second rib plate 5 can be increased to avoid damage to the workpiece or vehicle by the first rib plate 4 and the second rib plate 5, on the other hand, the exposed area of the concrete layer between the first rib plate 4 and the second rib plate 5 can be reduced, thereby reducing the damage to the concrete layer. It should be noted that in order to ensure that the space below the first horizontal plate and the second horizontal plate has enough concrete for support, therefore, special attention should be paid to the uniformity of the vibrating process. As a preferred embodiment, 100mm*100mm angle steel can be selected as the first rib plate 4 and the second rib plate 5, and the connecting joints are welded, the whole is welded and fixed after cutting, and the connecting strength is further enhanced. The spacing between the first rib plate 4 and the second rib plate 5 can be selected as 2m or 3m, and the top surface of the angle steel is flush with the top elevation of the concrete. The total number of angle steels or the first rib plate 4 and the second rib plate 5 is determined according to the required floor bearing capacity. The first rib plate 4 and the second rib plate 5 can also be assembled first, and then the first horizontal plate and the second horizontal plate are welded on the top of the first rib plate 4 and the second rib plate 5 after the assembly of the first rib plate 4 and the second rib plate 5 is completed. The overall structure can be T-shaped with the top horizontal plate protruding at both ends, or inverted L-shaped with only the left side or the right side protruding. Attention should be paid to the avoidance of the limiting groove 8 during the welding process.
[0030] As a preferred embodiment, the steel mesh layer 2 covers the entire heavy load floor projection range, and the reinforcing grid layer 3 is uniformly distributed in the heavy load floor projection range.
[0031] In this embodiment, on the one hand, the steel mesh layer 2 can connect the heavy load floors to form a whole, thereby effectively dispersing the heavy load, on the other hand, the flexibility of the device can be enhanced, so that the distribution of the reinforcing grid layer 3 can be adjusted according to the actual situation of the construction site.
[0032] As a preferred embodiment, the reinforcing grid layer 3 is further provided with a concrete buffer layer 9 above.
[0033] In this embodiment, by setting the concrete buffer layer 9, the heavy load vehicle or workpiece can avoid direct contact with the first rib plate 4 and the second rib plate 5 in the initial state, and the floor can be quickly repaired when the heavy load floor is empty.
[0034] As a preferred embodiment, the reinforcement mesh layer 3 is fixedly connected to the steel mesh layer 2 via connecting ribs.
[0035] In this embodiment, the reinforcing mesh layer 3 is directly fixedly connected to the steel mesh layer 2 by connecting ribs, so that the position of the reinforcing mesh layer 3 can be fixed in the initial state, so that the entire heavy-loaded floor can be poured at one time, avoiding the problem of having to wait for the concrete poured once to gain strength before the second pouring. This effectively reduces the pouring and construction time of the heavy-loaded floor and shortens the construction period.
