Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of edge protection structures, in particular to an edge protection structure for a trench or equipment foundation. Background Art
[0002] In current industrial buildings, steel cover plates are often used in equipment foundations or trenches. There are generally three ways to deal with the contact surface between the steel cover plate and the equipment foundation or trench concrete surface: one is to set an edge angle steel at the concrete angle, and the steel cover plate is supported on the angle steel. The disadvantage of this method is that the top surface of the cover plate is not in the same plane as the finished concrete surface, which affects the passage of personnel and machinery; the other is to lower the edge angle steel according to the thickness of the steel cover plate to ensure that the finished surface of the steel cover plate is flush with the finished surface of the concrete. The disadvantage of this method is that the corner concrete is easily broken; another is to cut the edge angle steel. Because the thickness of the commonly used steel cover plate is generally 5mm to 10mm, it is difficult to make the concrete surface and the finished surface of the steel cover plate flush with the cut angle steel. In order to ensure that the cover plate can be installed and disassembled smoothly, the size of the cover plate stiffening rib is generally about 20mm smaller than the trench width, which causes the cover plate to be dislocated and hit the trench or equipment foundation side wall when people or machinery pass on the cover plate.
[0003] In the related art, the technical problems of easy breakage of corner concrete and misalignment of cover plates during traffic have not yet been effectively solved. Utility Model Content
[0004] The utility model aims to provide a trench or equipment foundation edge protection structure to solve the problems in the related art that the corner concrete is easily broken and the cover plate is misplaced during the passage.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A trench or equipment foundation edge protection structure, including edge protection angle steel, which is installed on the edge corners of the equipment foundation, and the edge protection angle steel includes an upper steel plate and a side steel plate; the edge protection steel plate is welded to the outside of the upper steel plate of the edge protection angle steel; and the limit spring steel plate is bonded to the outside of the side steel plate of the edge protection angle steel.
[0007] It is further configured as follows: the edge protection angle steel is anchored to the equipment foundation through an anchor plate.
[0008] It is further configured as follows: the anchor plate and the upper steel plate of the edge protection angle steel are at an angle of 45 degrees.
[0009] It is further configured as follows: the tail of the anchor plate is located inside the equipment foundation; two anchor plate branches are arranged at the tail of the anchor plate, and an angle of 45 degrees is formed between the two anchor plate branches.
[0010] It is further configured as follows: the upper steel plate of the edge protection angle steel is overlapped with a steel cover plate.
[0011] It is further configured as follows: the height of the steel cover plate is the same as the height of the edge protection steel plate.
[0012] It is further configured as follows: the side surface of the steel cover plate abuts against the limit spring steel plate.
[0013] It is further configured as follows: the side steel plates of the edge protection angle steels are fixedly connected with support plates.
[0014] It is further configured as follows: the support plate and the side steel plate of the edge protection angle steel are at an angle of 45 degrees.
[0015] It is further configured as follows: the support plate abuts against the lower edge of the steel cover plate.
[0016] Compared with the prior art, the beneficial technical effects of the utility model are:
[0017] By setting edge protection steel plates and limit spring steel plates on the edge protection angle steels, it can be ensured that the completed construction surface of the steel cover plate and the completed construction surface of the equipment foundation or the trench side wall are on the same plane, which is convenient for the passage of personnel and machinery. At the same time, it can effectively solve the problems of easy breakage of corner concrete and misalignment of the cover plate during passage.
[0018] From the foundation anchoring of the edge protection angle steel, to the specific angle connection between the support plate and the side steel plate, to the precise positioning of the limit spring steel plate, the entire system effectively improves the stability of the equipment foundation. This ensures that the equipment can remain stable under various working conditions and reduces the risk of failure and accidents caused by unstable foundations. Through carefully designed angles and structures, such as the 45-degree angle connection between the support plate and the side steel plate, the system can distribute the externally applied force more efficiently, reduce stress concentration, and thus extend the service life of the equipment foundation. The steel cover not only provides a smooth transportation surface for the equipment, but also provides additional protection for the equipment foundation, further improving the operating efficiency and stability of the equipment. The structural design of the entire system takes into account the convenience of installation and maintenance. For example, the internal design of the anchor plate and the fixed connection of the support plate make the installation process simpler and also facilitate subsequent maintenance and overhaul work. The application of the limit spring steel plate effectively offsets the deformation of the steel cover, reduces the possibility of bending of the steel cover, and improves the smoothness and comfort of the equipment operation. Every part of the system has been carefully designed to achieve the optimal use of materials and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example
[0031] Reference Figure 1-Figure 5 , is a trench or equipment foundation edge protection structure disclosed by the utility model, the utility model includes: edge protection angle steel, the edge protection angle steel is installed on the edge corners of the equipment foundation, the edge protection angle steel includes an upper steel plate and a side steel plate; the edge protection steel plate, the edge protection steel plate is welded to the outside of the upper steel plate of the edge protection angle steel; the limiting spring steel plate, the limiting spring steel plate is bonded to the outside of the side steel plate of the edge protection angle steel.
[0032] Specifically, the edge protection angle steel is installed on the corners of the equipment foundation and is used to overlap the steel cover plate to make the steel cover plate more stable. Other components are also provided on the edge protection angle steel to cooperate with the overlapping steel cover plate, and can also increase the service life of the equipment foundation. The edge protection steel plate is welded to the outside of the upper steel plate of the edge protection angle steel, so that the equipment foundation or the edge of the ditch is in horizontal contact with the steel cover plate, making the equipment more stable when running on the steel cover plate. The limiting spring steel plate is bonded to the outside of the side steel plate of the edge protection angle steel, which can limit the deformation of the steel cover plate and ensure the correct position and stability of the steel cover plate. The limiting spring steel plate has a certain elasticity, which can reduce the vibration of the equipment during transportation and improve the stability and comfort of the equipment. The structure and installation method of the edge protection angle steel, edge protection steel plate and limiting spring steel plate are relatively simple, which is convenient for maintenance and replacement, and reduces the maintenance cost and use cost.
[0033] It is further configured as follows: the edge protection angle steel is anchored to the equipment foundation through an anchor plate. The anchor plate and the upper steel plate of the edge protection angle steel are at an angle of 45 degrees. The tail of the anchor plate is located inside the equipment foundation; two anchor plate branches are arranged at the tail of the anchor plate, and the two anchor plate branches are at an angle of 45 degrees.
[0034] Specifically, by anchoring the anchor plate to the equipment foundation, the edge angle steel can be more firmly fixed on the equipment foundation, thereby improving the overall stability. This helps prevent the equipment from being displaced during operation. The design of the anchor plate and the upper steel plate of the edge angle steel at a 45-degree angle can optimize the force distribution, so that the force is more evenly transmitted to the equipment foundation, reducing stress concentration and possible local damage. The tail of the anchor plate is located inside the equipment foundation. Such a design can better adapt to the foundation structure during installation and reduce the difficulty of installation. At the same time, since the tail of the anchor plate is located inside the foundation, the anchor plate is more stable. Two anchor plate branches are provided at the tail of the anchor plate, and the two anchor plate branches are at a 45-degree angle. This design increases the force-bearing area of the anchor plate, improves the anchoring capacity, and makes the edge angle steel more firmly fixed on the equipment foundation. The equipment foundation can also be a trench, which is specifically a concrete structure. The utility model can also adopt other anchoring forms according to the actual force conditions.
[0035] It is further configured as follows: the upper steel plate of the edge protection angle steel is overlapped with a steel cover plate. The height of the steel cover plate is the same as the height of the edge protection steel plate. The side of the steel cover plate abuts against the limit spring steel plate.
[0036] Specifically, when the equipment is transported on the steel cover, the equipment can move more smoothly due to the support of the steel cover, reducing the bumps or vibrations that may occur during transportation. The design of the steel cover can provide a smoother and safer walking surface, which can reduce the risk of people falling or equipment slipping. Using the steel cover as the basis for moving equipment can simplify the process of moving the equipment, because the steel cover is usually flatter and stronger, making the movement of the equipment more convenient and stable. Since the steel cover provides a smoother and safer transportation surface, the need for adjustment or fixation of the equipment during transportation can be reduced, thereby improving the transportation efficiency of the equipment. Since the use of the steel cover can reduce the risk of damage and accidents during transportation, the relevant insurance costs and maintenance costs can be reduced. The thickness and size of the limit spring steel plate are determined according to the size of the end of the steel cover from the edge of the concrete structure, the weight of the cover, the personnel passing on the cover and the mechanical load. It can not only provide effective lateral support for the steel cover, but also realize the free installation and removal of the steel cover; the limit steel plate can also be replaced by other elastic materials with a certain strength.
[0037] It is further configured that: the side steel plate of the edge protection angle steel is fixedly connected with a support plate, the support plate and the side steel plate of the edge protection angle steel are at an angle of 45 degrees, and the support plate abuts against the lower edge of the steel cover plate.
[0038] Specifically, the design of the support plate and the side steel plate at a 45-degree angle can enhance the overall stability, provide better support, and prevent the steel cover from bending or displacement when subjected to external forces. By abutting the support plate against the lower edge of the steel cover, the force distribution can be optimized, so that the force can be more evenly transmitted to the equipment foundation, reducing stress concentration and possible local damage. The design of the support plate can enhance the stability of the steel cover and prevent it from deformation or displacement when subjected to external forces. Since the support plate is fixedly connected to the side steel plate, this design can better adapt to the basic structure during installation and reduce the difficulty of installation. At the same time, since the support plate abuts against the lower edge of the steel cover, it is also convenient for future maintenance and overhaul.
[0039] Reference Figure 6 , Figure 6This is the overall installation diagram of the utility model. The edge protection structure adds edge protection steel plates and limit spring steel plates on the basis of the commonly used edge protection angle steels, which can ensure that the construction completion surface of the cover plate and the construction completion surface of the concrete structure are in the same plane, which is convenient for personnel and machinery to pass through. At the same time, it can effectively solve the problem that the concrete in the corners is easy to break and the cover plate is misplaced during the passage. For example, the steel cover plate is an 8mm thick patterned steel plate with a lap length of 50mm on each side. The edge protection angle steel L70x5.0 and the edge protection steel plate -30x8 can be selected. The two are connected by intermittent fillet welds, and the length is determined according to the range of the steel cover plate. The side of the edge protection angle steel is bonded with a limit spring steel plate with structural adhesive. The height of the arc part of the limit steel plate should be greater than the distance between the steel cover plate and the equipment foundation or the side wall of the trench, to ensure that the arc part of the limit steel plate is squeezed and deformed by the stiffening plate, so as to provide lateral support for the cover plate and ensure that the cover plate does not move misaligned.
[0040] The working principle and beneficial effects of the utility model are:
[0041] From the foundation anchoring of the edge protection angle steel, to the specific angle connection between the support plate and the side steel plate, to the precise positioning of the limit spring steel plate, the entire system effectively improves the stability of the equipment foundation. This ensures that the equipment can remain stable under various working conditions and reduces the risk of failure and accidents caused by unstable foundations. Through carefully designed angles and structures, such as the 45-degree angle connection between the support plate and the side steel plate, the system can distribute the externally applied force more efficiently, reduce stress concentration, and thus extend the service life of the equipment foundation. The steel cover not only provides a smooth transportation surface for the equipment, but also provides additional protection for the equipment foundation, further improving the operating efficiency and stability of the equipment. The structural design of the entire system takes into account the convenience of installation and maintenance. For example, the internal design of the anchor plate and the fixed connection of the support plate make the installation process simpler and also facilitate subsequent maintenance and overhaul work. The application of the limit spring steel plate effectively offsets the deformation of the steel cover, reduces the possibility of bending of the steel cover, and improves the smoothness and comfort of the equipment operation. Every part of the system has been carefully designed to achieve the optimal use of materials and costs.
