Description

Technical Field

[0001] The invention relates to the field of logistics and warehousing, and in particular to a lifting platform infrastructure used at an import and export of a logistics warehouse. Background Art

[0002] In the field of logistics and warehousing, a lifting platform is usually required to be installed at the entrance and exit of the warehouse. The lifting platform is an important equipment that is indispensable for the storage and retrieval of goods in the warehouse. When storing and retrieving goods, the goods enter and exit the warehouse through the lifting platform. The foundation on which the lifting platform is located often needs to have a large bearing capacity, high stability and certain deformability to meet the requirements of the warehouse. The conventional structure of the foundation structure of the existing tailgate slot lifting platform is a concrete bottom plate + vertical sintered solid brick wall. The foundation is located on the top surface of the bearing layer. A vertical sintered solid brick wall is set on the foundation. A reinforced concrete lifting platform plate is set on the top surface of the wall, and then a vertical sintered solid brick wall is set. The force is transmitted in the way of "brick wall → concrete plate → brick wall → foundation → foundation". However, in actual engineering, in order to ensure the support width of the concrete slab and the outer backfill soil and load, the solid brick wall will increase accordingly. As the thickness of the solid brick wall increases, the self-weight of the entire foundation increases, and the bottom surface area of ​​the foundation needs to be increased, which greatly increases the construction cost. The comprehensive cost is greatly increased, and it is urgent to improve the foundation of the lifting platform with a tailgate slot. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1-4As shown, the lifting platform foundation structure for the entrance and exit of the logistics warehouse described in the present invention comprises a plain concrete cushion layer 1 laid on the foundation and a concrete foundation 2 cast on the plain concrete cushion layer 1, a lower concrete wall 3 with an opening on one side is cast on the concrete foundation 2, a platform bottom plate 4 for supporting the lifting platform is cast on the top of the lower concrete wall 3, an upper concrete wall 5 with a side entrance and exit on one side is cast on the platform bottom plate 4, the side entrance and exit of the upper concrete wall 5 and the side opening direction of the lower concrete wall 3 are consistent, and both are located outside the warehouse; the upper concrete wall 5 and the platform bottom plate 4 form a slot with a side opening, the slot has a first section and a second section, and the width of the first section is d 1 Greater than the width of the second paragraph d 2 , that is, the slot expansion setting is convenient for the entry and exit of the rear of the freight truck, providing a certain space for its tailboard, thereby realizing the connection between the rear of the freight truck and the lifting platform, and facilitating the entry and exit of goods; A mounting hole 10 is provided on one side wall of the lower concrete enclosure 3 , and the mounting hole is opposite to the side opening of the lower concrete enclosure 3 , which is convenient for installing the HVAC duct, thereby reducing the antifreeze investment and operating costs.

[0021] During actual construction, after the plain concrete layer solidifies, the steel cage of the concrete foundation 2 is tied, and the steel cage of the lower concrete wall 3 is tied thereon, the lower part of the steel cage of the lower concrete wall 3 and the steel cage of the concrete foundation 2 are tied together, and then the concrete foundation 2 is poured; after the concrete foundation 2 reaches the design strength, the steel cage of the platform bottom plate 4 is tied to the steel cage of the lower concrete wall 3, and then the lower concrete wall 3 is poured; after the lower concrete wall 3 reaches the design strength, the upper concrete wall 5 is tied to the steel cage of the platform bottom plate 4, and then the platform bottom plate 4 and the upper concrete wall 5 are poured, and the steel cages of the concrete foundation 2, the lower concrete wall 3, the platform bottom plate 4 and the upper concrete wall 5 are tied together, which effectively improves the structural strength and stability.

[0022] During actual construction, the steel cages of the concrete foundation 2, the lower concrete wall 3, the platform floor 4 and the upper concrete wall 5 can be tied in sequence first, and then cast as a whole: first tie the steel cage of the concrete foundation 2 (composed of longitudinal steel bars and transverse steel bars); then tie the steel cage of the lower concrete side wall, which has vertical steel bars and horizontal steel bars, the horizontal steel bars and the vertical steel bars are tied together, and the lower part of the vertical steel bars is tied together with the steel cage of the concrete foundation 2; tie the steel cage of the platform floor 4 to the steel cage of the lower concrete wall 3, and tie the steel cage on the platform floor 4 to the steel cage of the upper concrete side wall, so that their steel cages are tied together to form a whole, and then cast as a whole to ensure the structural strength and stability of the entire foundation.

[0023] Combination Figure 1 , 4 -7 It can be seen that anti-collision rubber blocks 6 are provided on the outer end faces and corner end faces of the upper concrete fence 5. The outer end faces and corner end faces are both parts that are prone to collision. The anti-collision rubber blocks 6 can effectively protect the upper concrete fence 5 to prevent the rear end of a freight truck from entering and causing damage to the fence due to collision. In order to further protect the concrete walls at these parts that are prone to collision, a reinforcing steel plate 7 can be pre-buried at each part that is prone to collision when the steel cage of the upper concrete fence 5 is in place. A plurality of anchor bars 8 are welded to the inner surface of the reinforcing steel plate 7, and the anchor bars 8 are anchored in the upper concrete fence 5. In order to facilitate the installation of the anti-collision rubber block 6, an anchor bolt 9 with an L-shaped structure is pre-buried when the reinforcing steel plate 7 is pre-buried. The threaded connector of the anchor bolt 9 passes through the reinforcing steel plate 7 and the upper concrete fence 5 outwardly. A countersunk hole corresponding to the anchor bolt 9 is opened on the anti-collision rubber block 6. The threaded connector is located in the countersunk hole of the anti-collision rubber block 6. The anti-collision rubber block 6 can be fixedly installed by screwing the tightening nut. After being put into use, when the anti-collision rubber block 6 is damaged, the upper concrete wall 5 can be protected by the reinforcing steel plate 7, so as to avoid damage to the upper concrete wall 5 as much as possible, extend the maintenance cycle, and facilitate timely replacement of new anti-collision rubber blocks 6.
