Description

Technical Field

[0001] This utility model relates to the field of freight ramp technology, specifically to a freight ramp anti-settlement structure. Background Technology

[0002] During the construction of industrial plant buildings, the internal platform is usually higher than the external ground, which requires the construction of freight ramps to facilitate the entry and exit of equipment and machinery. As an important functional component connecting the site and the interior of the building, the junction of the freight ramp and the main building is a sensitive area for settlement and deformation issues.

[0003] Because the two structures usually differ in terms of structural form, load size, foundation type and burial depth, they are prone to uneven settlement. In addition, long-term exposure to heavy vehicles (such as forklifts and trucks) can easily lead to height differences, cracks or even structural damage between the ramp and the main structure, affecting normal use and posing safety hazards.

[0004] Therefore, it is necessary to invent a settlement-preventing structure for freight ramps to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a settlement-preventing structure for freight ramps, in order to solve the problem that existing ramp structures are subject to settlement and vehicle traffic over long periods of time, which can easily lead to height differences, cracks, or even structural damage with the main building, affecting normal use and posing safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a freight ramp anti-settlement structure, comprising a ground beam body, on the side of which a ramp body is cast. The ramp body structure includes a compacted soil layer, a crushed stone cushion layer, a concrete layer, embedded reinforcement bars, reinforcing bars, a cast-in-place cantilever beam, a support beam, and reinforcing bars. The cast-in-place cantilever beam is cast on the right side of the ground beam body. Embedded reinforcement bars and reinforcing bars are provided inside the cast-in-place cantilever beam. The left end of the embedded reinforcement bars is fixed inside the ground beam body, and the reinforcing bars are tied to the right end of the embedded reinforcement bars. Reinforcing bars are provided inside the concrete layer, and the left end of the reinforcing bars is fixed to the upper side of the cast-in-place cantilever beam.

[0007] By adopting the above technical solution, the cast-in-place cantilever beam, embedded reinforcement and reinforcing bars are used to support the left end of the ramp main body, and the pressure at the left end of the ramp main body is transmitted to the interior of the ground beam main body, so that the ramp main body and the building main body settle synchronously, and improve the compressive strength of the left end of the ramp main body. At the same time, the reinforcing bars improve the bearing capacity of the concrete layer, thereby effectively avoiding the height difference and cracks between the ramp and the building main body, and improving the service life and safety of the ramp main structure.

[0008] Optionally, a support beam is cast on the upper side of the cast-in-place cantilever beam, and an indoor platform is cast on the upper end of the main body of the ground beam and the support beam.

[0009] By adopting the above technical solution, the support beam is used to support one side of the indoor platform.

[0010] Optionally, the compacted soil layer is placed at the bottom layer of the main structure of the ramp.

[0011] By adopting the above technical solution, the subsoil compaction layer is directly compacted using subsoil, and this process is carried out after the main body of the ground beam and the cast-in-place cantilever beam are poured.

[0012] Optionally, the crushed stone cushion layer is laid on the upper side of the compacted soil layer, the left end of the crushed stone cushion layer is higher than the height of the cast-in-place cantilever beam, and the thickness of the crushed stone cushion layer is 300mm.

[0013] By adopting the above technical solution, the crushed stone cushion layer is used to improve the load-bearing capacity of the main body of the ramp, while further improving the anti-settlement capacity.

[0014] Optionally, the concrete layer is poured on the upper side of the crushed stone cushion layer and the cast-in-place cantilever beam, and the concrete layer is 200mm thick C20 concrete.

[0015] By adopting the above technical solution, the concrete layer is used to improve the compressive strength of the main body of the ramp.

[0016] Optionally, an expansion joint is provided between the left end of the concrete layer and the supporting beam.

[0017] By adopting the above technical solution, expansion joints are used to prevent damage to the main ramp caused by thermal expansion and contraction.

[0018] Optionally, the upper surface of the concrete layer may have multiple sets of transverse anti-slip grooves.

[0019] By adopting the above technical solution, the interval between two adjacent anti-skid grooves is 50mm, which increases the friction between the vehicle tires and the main body of the ramp, avoids slippage, and improves operational safety.

[0020] Optionally, guide walls are cast on both the front and rear sides of the concrete layer and the crushed stone cushion layer.

[0021] By adopting the above technical solution, the guide wall and the cast-in-place cantilever beam are poured simultaneously to support both sides of the main body of the ramp and prevent collapse.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model utilizes cast-in-place cantilever beams, embedded bars, and reinforcing bars to support the left end of the ramp main body, transmitting the pressure from the left end of the ramp main body to the interior of the ground beam main body. This allows the ramp main body and the building main body to settle synchronously, and improves the compressive strength of the left end of the ramp main body. At the same time, the reinforcing bars improve the bearing capacity of the concrete layer, thereby effectively preventing height differences and cracks between the ramp and the building main body, and improving the service life and safety of the ramp main structure. 2. This utility model improves the compressive strength by simultaneously casting the cast-in-place cantilever beam and guide wall into one piece, while using the guide wall to support both sides of the ramp body to prevent the ramp body from collapsing to both sides, thus further improving the structural strength of the ramp body.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 3The diagram shows a freight ramp anti-settlement structure, including a ground beam body 1. A ramp body 3 is cast on the side of the ground beam body 1. The ramp body 3 consists of a compacted soil layer 31, a crushed stone cushion layer 32, a concrete layer 33, embedded reinforcing bars 34, reinforcing bars 35, a cast-in-place cantilever beam 36, a support beam 37, and reinforcing bars 39. The cast-in-place cantilever beam 36 is cast on the right side of the ground beam body 1. Embedded reinforcing bars 34 and reinforcing bars 35 are installed inside the cast-in-place cantilever beam 36, with the left end of the embedded reinforcing bars 34 fixed. Inside the main body 1 of the ground beam, the reinforcing bar 35 is tied to the right end of the pre-embedded bar 34. The concrete layer 33 is provided with reinforcing bar 39. The left end of the reinforcing bar 39 is fixed to the upper side of the cast-in-place cantilever beam 36. A support beam 37 is poured on the upper side of the cast-in-place cantilever beam 36. An indoor platform 2 is poured on the upper end of the main body 1 of the ground beam and the support beam 37. Multiple sets of transverse anti-slip grooves 4 are opened on the upper surface of the concrete layer 33. Guide walls 5 are poured on both the front and rear sides of the concrete layer 33 and the crushed stone pad layer 32.

[0027] Among them, the cast-in-place cantilever beam 36 and guide wall 5 are cast in one piece to improve compressive strength. The guide wall 5 supports the inner crushed stone cushion layer 32 and concrete layer 33 on both sides to prevent them from collapsing to both sides, and at the same time to prevent the ramp body 3 from being stretched to both sides during use, which could cause the middle of the ramp body 3 to break.

[0028] Meanwhile, the inner side of the embedded reinforcement 34 is fixed inside the ground beam body 1, and the reinforcing reinforcement 35 is tied to the outer end of the embedded reinforcement 34. The cast-in-place cantilever beam 36, the embedded reinforcement 34 and the reinforcing reinforcement 35 work together to support the left end of the ramp body 3, and transmit the pressure of the left end of the ramp body 3 to the interior of the ground beam body 1, so that the ramp body 3 and the building body settle synchronously, and improve the compressive strength of the left end of the ramp body 3.

[0029] See Figure 1 and Figure 2 The compacted soil layer 31 is set at the bottom of the main structure of the ramp 3. The crushed stone cushion layer 32 is laid on the upper side of the compacted soil layer 31. The left end of the crushed stone cushion layer 32 is higher than the height of the cast-in-place cantilever beam 36. The thickness of the crushed stone cushion layer 32 is 300mm. The concrete layer 33 is poured on the upper side of the crushed stone cushion layer 32 and the cast-in-place cantilever beam 36. The concrete layer 33 is 200mm thick C20 concrete. An expansion joint 38 is set between the left end of the concrete layer 33 and the support beam 37.

[0030] Specifically, during the pouring of the main body 3 of the ramp: First, pre-embedded holes are opened on the side of the main body 1 of the ground beam, and the left end of the pre-embedded reinforcement 34 is inserted into the pre-embedded hole and fixed. Then, the reinforcing reinforcement 35 is tied to the left end of the pre-embedded reinforcement 34. Install the formwork for the cast-in-place cantilever beam 36 and the support beam 37 on the outside of the embedded reinforcement 34 and the reinforcing reinforcement 35, and install the formwork for the guide wall 5 at both ends of the embedded reinforcement 34 and the reinforcing reinforcement 35. Pour C20 concrete inside the formwork, and remove the formwork after it has set. The soil layer between the two sets of guide walls 5 is compacted into a plain soil compacted layer 31. The crushed stone is laid on the upper side of the compacted soil layer 31 and compacted to form a 300mm thick crushed stone cushion layer 32. Next, pre-embedded holes are opened on the surface of the cast-in-place cantilever beam 36, and the left end of the reinforcing bar 39 is fixed inside the pre-embedded hole. The right half of the reinforcing bar 39 overlaps the upper side of the crushed stone cushion layer 32. Then fix the formwork on the upper surface of the cast-in-place cantilever beam 36, pour 200mm thick C20 concrete on the upper side of the crushed stone cushion layer 32 and the cast-in-place cantilever beam 36 to form a concrete layer 33, and then cure it. Finally, multiple sets of anti-slip grooves 4 are opened on the upper surface of the concrete layer 33, with a 50mm interval between two adjacent sets of anti-slip grooves 4.

[0031] The working principle of this utility model is as follows: A cast-in-place cantilever beam 36 is poured on the side of the main body of the ground beam 1, and the soil layer below it is compacted to form a plain soil compacted layer 31. Then, a crushed stone cushion layer 32 is laid on its surface, and a concrete layer 33 is poured on the upper side of the crushed stone cushion layer 32 and the cast-in-place cantilever beam 36. The cast-in-place cantilever beam 36, the pre-embedded reinforcement 34 and the reinforcing reinforcement 35 are used to support the left end of the main body of the ramp 3, and the pressure of the left end of the main body of the ramp 3 is transmitted to the interior of the main body of the ground beam 1, so that the main body of the ramp 3 and the main body of the building settle synchronously, and the compressive strength of the left end of the main body of the ramp 3 is improved. At the same time, the reinforcing reinforcement 39 is used to improve the bearing capacity of the concrete layer 33, thereby effectively avoiding the height difference and cracks between the main body of the ramp 3 and the main body of the building, and improving the service life and safety of the ramp 3 structure.
