[0033] The following further elaborates on the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant invention and do not limit the invention. Additionally, it should be noted that for ease of description, only the parts related to the invention are shown in the drawings.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the accompanying drawings and embodiments.

[0035] Referring to Figures 1 to 9 As shown, the present invention provides a floor at the entrance of a factory cargo elevator, including: a water-stable layer 1, a concrete base layer 2, a support component 3, a concrete intermediate layer 5, and a supporting steel panel 4.

[0036] In this embodiment, the water-stable layer 1 is paved on the foundation. The thickness of the water-stable layer 1 is 300 mm. The water-stable layer 1 can bear a large load.

[0037] The concrete base layer 2 is poured on the water-stable layer 1. The concrete base layer 2 adopts a reinforced concrete structure.

[0038] The number of support components 3 is multiple. The height of the support component 3 is adjustable. The lower part of the support component 3 is buried in the concrete base layer 2. The upper part of the support component 3 extends above the upper surface of the concrete base layer 2. The tops of the multiple support components are flush and on the same horizontal plane.

[0039] The supporting steel panel 4 is installed on the multiple support components 3. A post-casting space is formed between the supporting steel panel 4 and the concrete base layer 2.

[0040] Concrete is poured into the post-casting space. The concrete consolidates to form the concrete intermediate layer 5. After the concrete is poured, the function of the support component 3 is not only to adjust and support the supporting steel panel 4, but also to provide a certain connection force for the connection between the concrete base layer 2 and the concrete intermediate layer 5.

[0041] As a preferred embodiment, a first steel mesh 21 is embedded in the concrete base layer 2. The first steel mesh 21 in the concrete base layer 2 is a single-layer bidirectional A14 steel mesh. The first steel mesh 21 is erected on the cement stabilized layer 1 through stools.

[0042] As a preferred embodiment, the lower part of the support assembly 3 is connected to the first steel mesh 21. In this embodiment, the bottom of the support assembly 3 is welded to the first steel mesh 21.

[0043] In this embodiment, the concrete intermediate layer 5 is a reinforced concrete structure. Specifically, a second steel mesh 51 is erected in the post-pouring space. The second steel mesh 51 is erected on the concrete base layer 2 through stools. The concrete is coated on the second steel mesh 51.

[0044] Preferably, the second steel mesh 51 is a simple bidirectional A10 steel mesh. By respectively arranging steel meshes in the concrete base layer 2 and the concrete intermediate layer 5, the laying of the steel meshes strengthens the ground structure, which helps to improve the bearing capacity and crack resistance of the ground.

[0045] As a preferred embodiment, the concrete is micro-expansion fine aggregate concrete. Using micro-expansion fine aggregate concrete for the concrete intermediate layer 5 can increase the crack resistance of the ground.

[0046] In this embodiment, the support assembly 3 includes a threaded sleeve 31 and a screw rod 32.

[0047] The two threaded sleeves 31 are coaxially arranged. The lower end of one threaded sleeve 31 is embedded in the concrete base layer 2. The upper end of the other threaded sleeve 31 is connected to the supporting steel panel 4. The two ends of the screw rod 32 are respectively screwed to the two threaded sleeves 31.

[0048] Preferably, the spiral directions of the threads at both ends of the screw rod 32 are opposite. When adjusting the height of the other threaded sleeve 31, only the screw rod 32 needs to be rotated to quickly adjust the top elevation of the other threaded sleeve 31.

[0049] A base plate 33 is connected to the upper end of the other threaded sleeve 31. The supporting steel panel 4 is laid on the base plates 33 of a plurality of support assemblies 3. In this embodiment, first, the base plate 33 on the other threaded sleeve 31 is welded to the back of the supporting steel panel 4. After the concrete base layer 2 is poured, the other threaded sleeve 31 is screwed to the screw rod 32 on the concrete base layer 2. The levelness and elevation of the front surface of the supporting steel panel 4 are adjusted by rotating the screw rod 32.

[0050] Preferably, a base plate 33 is connected to the lower end of one threaded sleeve 31. The threaded sleeve 31 is arranged at the plane center of the base plate 33.

[0051] The supporting steel panel 4 is made of stainless steel anti-slip steel plate.

[0052] The present invention provides a construction method for the ground at the entrance of a factory building's freight elevator, comprising the following steps:

[0053] S1. Lay a water-stabilized layer 1 on the foundation.

[0054] Refer to Figure 4 As shown, according to the factory building floor construction method, construct a 300-mm-thick water-stabilized layer 1 on the foundation. The water-stabilized layer 1 can bear a large load, and the water-stabilized layer 1 is compacted in layers.

[0055] Combine Figure 5 and Figure 6 As shown, lay a single-layer bidirectional A14 steel bar mesh on the water-stabilized layer 1, position one threaded sleeve 31 of the support assembly 3, and weld the base plate 33 at the bottom of one threaded sleeve 31 to the steel bars.

[0056] S2. Pour a concrete base layer 2 on the water-stabilized layer 1. When pouring the concrete base layer 2, bury the lower parts of multiple support assemblies 3 in the concrete base layer 2.

[0057] Refer to Figure 7 As shown, conduct a 100-mm concrete floor pouring construction once to form the concrete base layer 2.

[0058] S3. Adjust the heights of multiple support assemblies 3 so that the top surfaces of multiple support assemblies 3 are on the same horizontal plane.

[0059] Lay a single-layer bidirectional A10 steel bar mesh on the concrete base layer 2 again. This step is carried out after the first concrete pouring. The laying of the steel bar mesh provides a further strengthening structure for the ground, helping to improve the bearing capacity and crack resistance of the ground.

[0060] After laying the second steel bar mesh 51, position and weld the base plate 33 of the other threaded sleeve 31 of the support assembly 3 to the supporting steel panel 4. The welding operation needs to ensure firm connection and accurate position to ensure that the supporting steel panel 4 can be stably fixed on the other threaded sleeve 31 of the support assembly 3 and will not loosen or displace during subsequent use.

[0061] Then conduct seamless butt joint positioning of the supporting steel panel 4, the position of the freight elevator, and one threaded sleeve 31 of the support assembly 3. This operation requires precise measurement and installation to ensure the connection of the supporting steel panel 4 with the position of the freight elevator and one threaded sleeve 31 of the support assembly 3, not only meeting the functional requirements but also ensuring the flatness and integrity of the ground.

[0062] Finally, rotate the screw rod 32 to control the elevation adjustment of the supporting steel panel 4. Elevation adjustment is a key link to ensure the flatness of the ground. Through the support assembly 3, the height of the ground can be finely adjusted to meet the elevation requirements of the design, ensuring that the entire ground reaches the standard in terms of levelness and providing a good foundation for subsequent use.

[0063] S4. Refer to Figure 9 As shown, install the supporting steel panel 4 on a plurality of support assemblies 3 so that a post-casting space is formed between the supporting steel panel 4 and the concrete base layer 2.

[0064] S5. Pour concrete into the post-casting space, and the concrete solidifies to form the concrete intermediate layer 5.

[0065] After the supporting steel panel 4 is installed, use slightly expanding fine aggregate concrete to pour into the post-casting space to solidify and form the concrete intermediate layer 5, increasing the anti-cracking performance of the ground and performing a secondary 100-mm concrete pouring.

[0066] The supporting steel panel 4 uses a 10-mm-thick stainless steel anti-slip plate. The stainless steel anti-slip plate can be directly and seamlessly docked with the ground at the position of the freight elevator car, ensuring the flatness of the ground, improving the wear resistance of the ground, and ensuring the service life.

[0067] The ground at the entrance of the freight elevator in the factory building of the present invention adopts a composite ground structure composed of a supporting steel panel, a concrete base layer, a concrete intermediate layer, and a water-stabilized layer, ensuring the safety of goods transportation, improving the wear resistance of the ground, increasing the durability of use, and ensuring the safety of equipment during the transfer process.

[0068] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
