Description

Technical Field

[0001] The present application relates to the field of steel grating platform construction, and in particular to a steel grating platform and a construction method thereof. Background Art

[0002] The steel grating plate is made of load-bearing flat steel and cross bars arranged in longitude and latitude at a certain interval, which are then welded into the original plate with a high-voltage resistance welding machine, and then further processed into the finished product through processes such as cutting, incision, opening, and edging.

[0003] In the field of construction engineering, with the rapid development of industrialization, the optimization of the construction method of the main plant steel grating platform and the safety protection during the construction process have become increasingly important. As an important part of large industrial plants, the construction quality and safety of the steel grating platform are directly related to the stability of the entire project and the life safety of personnel.

[0004] Traditional steel grating platform construction methods often involve complex process flows and multiple construction links, including embedded bolts, connection between steel columns and embedded bolts, installation of steel beams, and installation of steel gratings. The accuracy and construction quality of each of these steps directly affect the stability and safety of the final platform. However, the existing construction methods still have problems such as complex operations, low construction efficiency, and potential safety hazards in some links. During high-altitude operations and heavy lifting, it is difficult to ensure the safety of construction workers and the stability of construction quality. Summary of the invention

[0005] In order to improve construction quality and efficiency while ensuring the personal safety of construction workers, the present application provides a steel grating platform and a construction method.

The steel column is hoisted by a bridge crane to align with the embedded bolts. After tightening the nuts, re-tighten and final tighten; Installation of steel beams. After the steel column installation review is completed, the steel beams are installed. The steel beams are hoisted symmetrically at two points. After they are installed in place, they are fixed and bolts are tightened. After the steel grating is installed and the main and secondary steel beams are assembled, the steel grating is hoisted to the designated location and fixed with saddle clamps.

[0007] By adopting the above technical solution, construction workers can know exactly where to perform the pre-embedding work, thereby avoiding deviations or errors in construction, improving the quality of construction, ensuring the structural safety and stability of the building, and also helping to improve construction efficiency and reduce unnecessary rework and correction work; installing high-strength building anchors after drilling and cleaning. Drilling can provide space for the installation of anchors, and cleaning the dust and debris in the holes can ensure the close bonding between the anchors and the substrate. Leaving them to stand for 24 hours is to allow the adhesive or curing agent between the anchors and the substrate to have enough time to react chemically, thereby achieving the best bonding effect, so that the anchors can withstand greater tension and provide solid support for the building; the two-point symmetry keeps the steel beam stable to prevent it from swaying or tilting during the hoisting process, thereby reducing safety risks.

[0008] Preferably, the construction preparation also includes preparing construction tools, and the setting of construction tools includes using a scissor-type lifting platform and setting a vertical pole type safety rope.

[0009] By adopting the above technical solution, the scissor-type lifting platform is mainly used in construction sites, providing workers with a lifting work platform, which is convenient for construction workers to work at different heights and improve work efficiency. It also reduces the complexity and construction time of using traditional scaffolding and other equipment, and reduces the risk of working at heights; the main function of the vertical pole safety rope is to protect the personal safety of construction workers when performing high-altitude operations, provide effective protection when construction workers accidentally fall, reduce the damage caused by the fall, and ensure that construction workers are fully protected at any height.

[0010] Preferably, the use of the scissor lift platform includes a pre-startup check, and a start-up and operating check.

[0011] By adopting the above technical solution, inspection is a necessary step to ensure the safe operation of the equipment, including checking whether the hydraulic system, electrical system, structural components, etc. are intact, and confirming whether there are debris or obstacles on the platform, timely discovering and dealing with potential safety hazards, thereby reducing the risk of equipment failure; during the startup and operation of the scissor lift platform, continuous operational inspections are the key to ensuring the stable operation of the equipment, including monitoring the pressure, oil temperature and other parameters of the hydraulic system, checking the working status of the electrical system, and observing the stability and smoothness of the platform during lifting.

[0012] Preferably, the inspection before starting includes checking the effectiveness of the power cord, the electrical control box, the travel switch and each button, and checking the oil leakage of the oil pipeline, etc.

[0013] By adopting the above technical solution, the power cord, electrical control box and travel switch are the key parts of the equipment's electrical system. Checking their effectiveness can timely discover potential safety hazards, such as line aging, poor contact or switch failure, so as to take corresponding measures to repair them, ensure that the equipment operates in a safe state, timely discover and solve potential problems that may cause equipment failure, reduce the probability of equipment failure during operation, and improve the reliability and stability of the equipment; oil pipeline leakage will not only cause waste of resources, but also may cause damage to equipment and the environment. Timely inspection can avoid greater losses.

[0014] Preferably, the provision of the pole-type safety rope includes the provision of a pole and the installation of the safety rope.

[0015] By adopting the above technical scheme, the poles should be made of strong and stable materials, such as steel pipes or solid rods, to ensure that they can withstand the expected load. The poles are erected vertically and fixed deeply to the ground to prevent them from tilting or collapsing. At the same time, the height of the poles should be determined according to actual needs to ensure that the safety rope can play an effective role; the safety rope is mainly used to connect the staff and the safety belt to provide a safe fall prevention system. When the staff are working at high altitudes, the safety rope can effectively prevent them from falling and protect the lives of the staff. The safety rope should be made of high-strength, wear-resistant and corrosion-resistant materials to ensure that it will not break or be damaged during use.

[0016] Preferably, the arrangement of the vertical pole includes using a vertical pole type safety rope for protection on the edge of the steel beam and the steel beam for people to walk on, and using a vertical pole bottom clamp connection method between the vertical pole and the steel beam.

[0017] By adopting the above technical solution, the bottom clamp connection method can effectively connect the vertical pole and the steel beam together to form an integral structure, thereby enhancing the rigidity and stability of the entire structure. At the same time, the clamp connection can also be easily installed and disassembled, improving the flexibility and efficiency of construction, and avoiding destructive operations such as welding or punching on the steel beam, thereby protecting the integrity and strength of the steel beam. Further, it is convenient to adjust and repair the vertical pole, thereby improving the service life and safety of the structure.

[0018] Preferably, the installation of the safety rope includes using a φ9 galvanized steel wire rope, and using basket bolts of specification M8D at both ends of the steel wire rope to adjust the slackness of the safety rope.

[0019] By adopting the above technical solution, the safety rope uses φ9 galvanized steel wire rope, mainly to ensure the strength and corrosion resistance of the rope. The galvanized steel wire rope has excellent wear resistance, corrosion resistance, and fatigue resistance, and is suitable for use outdoors and in harsh environments, thereby improving the service life and safety of the safety rope; the M8D basket bolts used at both ends of the wire rope are mainly used to adjust the tension of the wire rope, as well as to connect and fix the wire rope. The appropriate tension can ensure the stability and reliability of the safety rope during use.

[0020] Preferably, the construction preparation also includes reserving hoisting space.

[0021] By adopting the above technical solution, reserving hoisting space can ensure the smooth progress of hoisting operations, thereby improving construction efficiency. In large buildings or complex engineering projects, hoisting operations are usually an indispensable link. Reserving space can avoid construction delays caused by insufficient space; reserving hoisting space can also avoid damage to the completed building structure during the hoisting process. In a narrow or complex construction environment, insufficient hoisting space may cause the equipment to collide with the building structure, resulting in losses.

[0022] Preferably, in the steel beam installation step, at least two lifting points are set for each steel beam, and the lifting rope adopts a lifting belt, and the installation accuracy is ensured by fine-tuning the large rope.

[0023] By adopting the above technical solution, the posture and position of the steel beam may be affected by many factors, such as wind force, the accuracy of the lifting equipment, the skill level of the operator, etc. In order to ensure the installation accuracy, fine-tuning is required during the lifting process. By using the lifting belt to fine-tune the rope at at least two lifting points, the position and posture of the steel beam can be controlled more accurately.

[0024] Preferably, railings need to be installed after the steel grille is installed.

[0025] By adopting the above technical solution, the main function of the railing is to provide safety protection to prevent people from falling from heights. After the steel grille is installed, the installation of the railing can further enhance the safety of the working platform or walkway.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Construction workers can know exactly where to carry out the pre-embedded work, thus avoiding deviations or errors in construction, improving the quality of construction, ensuring the structural safety and stability of the building, and also helping to improve construction efficiency and reduce unnecessary rework and correction work; installing high-strength building anchors after drilling and cleaning. Drilling can provide space for the installation of anchors, and cleaning the dust and debris in the holes can ensure the close bonding between the anchors and the substrate. Standing for 24 hours is to allow the adhesive or curing agent between the anchors and the substrate to have enough time for a chemical reaction, thereby achieving the best bonding effect, so that the anchors can withstand greater tension and provide stable support for the building; the two-point symmetry keeps the steel beam stable to prevent it from swaying or tilting during the hoisting process, thereby reducing safety risks. DETAILED DESCRIPTION

[0027] The present application is described in further detail below.

[0028] The embodiment of the present application discloses a steel grating platform and a construction method. The steel grating platform and the construction method include the following steps: S1. Construction preparation, including selecting a bridge crane that meets the working conditions and ensuring that it is not overloaded; Specifically, construction preparation also includes preparing construction tools, and setting up construction tools includes using a scissor lift platform and setting up a pole-type safety rope. The scissor lift platform is mainly used at the construction site to provide workers with a work platform that can be raised and lowered, making it easier for construction workers to work at different heights and improve work efficiency. It also reduces the complexity and construction time of using traditional scaffolding and other equipment, and reduces the risk of working at heights; the pole-type safety rope is mainly used to protect the personal safety of construction workers when performing high-altitude operations, provide effective protection when construction workers accidentally fall, reduce the damage caused by the fall, and ensure that construction workers are fully protected at any height.

[0029] Specifically, the use of the scissor lift platform includes pre-startup inspection, as well as startup and operation inspection. Inspection is a necessary step to ensure the safe operation of the equipment, including checking whether the hydraulic system, electrical system, structural components, etc. are intact, and confirming whether there are debris or obstacles on the platform, timely discovering and handling potential safety hazards, thereby reducing the risk of equipment failure; during the startup and operation of the scissor lift platform, continuous operation inspection is the key to ensure the stable operation of the equipment, including monitoring the pressure, oil temperature and other parameters of the hydraulic system, checking the working status of the electrical system, and observing the stability and smoothness of the platform during lifting.

[0030] Specifically, the inspection before starting includes checking the effectiveness of the power cord, electrical control box, travel switch and each button, as well as checking the oil leakage of the oil pipeline, etc. The power cord, electrical control box and travel switch are key parts of the equipment's electrical system. Checking their effectiveness can timely discover potential safety hazards, such as line aging, poor contact or switch failure, so as to take appropriate measures to repair them, ensure that the equipment operates in a safe state, timely discover and solve potential problems that may cause equipment failure, reduce the probability of equipment failure during operation, and improve the reliability and stability of the equipment; oil pipeline leakage will not only cause a waste of resources, but also may cause damage to the equipment and the environment. Timely inspection can avoid greater losses.

[0031] Specifically, the setting of the pole-type safety rope includes the setting of the pole and the installation of the safety rope. The pole should be made of strong and stable materials, such as steel pipes or solid poles, to ensure that it can withstand the expected load. The pole is vertically erected and deeply fixed to the ground to prevent it from tilting or collapsing. At the same time, the height of the pole should be determined according to actual needs to ensure that the safety rope can play an effective role; the safety rope is mainly used to connect the staff and the safety belt to provide a safe fall prevention system. When the staff is working at high altitude, the safety rope can effectively prevent them from falling and protect the lives of the staff. The safety rope should be made of high-strength, wear-resistant and corrosion-resistant materials to ensure that it will not break or be damaged during use.

[0032] Specifically, the setting of the pole includes using pole-type safety rope protection on the edge of the steel beam and the steel beam for people to walk on, and the pole bottom clamp connection method is used between the pole and the steel beam. The bottom clamp connection method can effectively connect the pole and the steel beam together to form an integral structure, thereby enhancing the rigidity and stability of the entire structure. At the same time, the clamp connection can also be easily installed and disassembled, improving the flexibility and efficiency of construction, and can also avoid destructive operations such as welding or drilling on the steel beam, protecting the integrity and strength of the steel beam. Further, it is convenient to adjust and repair the pole, and improve the service life and safety of the structure.

[0033] Specifically, the installation of the safety rope includes the use of φ9 galvanized steel wire rope, and the use of M8D basket bolts at both ends of the steel wire rope to adjust the slack of the safety rope. The use of φ9 galvanized steel wire rope for the safety rope is mainly to ensure the strength and corrosion resistance of the rope. The galvanized steel wire rope has excellent wear resistance, corrosion resistance, and fatigue resistance, and is suitable for outdoor and harsh environments, thereby improving the service life and safety of the safety rope; the M8D basket bolts used at both ends of the steel wire rope are mainly used to adjust the tension of the steel wire rope, as well as to connect and fix the steel wire rope. The appropriate tension can ensure the stability and reliability of the safety rope during use.

[0034] Specifically, construction preparation also includes reserving hoisting space. Reserving hoisting space can ensure the smooth progress of hoisting operations, thereby improving construction efficiency. In large buildings or complex engineering projects, hoisting operations are usually an indispensable link. Reserving space can avoid construction delays caused by insufficient space; reserving hoisting space can also avoid damage to the completed building structure during the hoisting process. In a narrow or complex construction environment, insufficient hoisting space may cause equipment to collide with the building structure, resulting in losses.

[0035] S2, embedded bolts, according to the drawing axis on-site measurement to mark the embedded point position, drilling and cleaning after the installation of high-strength building anchor bolts, let it stand for 24 hours before the next step of construction; Specifically, construction workers can know exactly where to perform the pre-embedded work, thereby avoiding deviations or errors in construction, improving the quality of construction, ensuring the structural safety and stability of the building, and also helping to improve construction efficiency and reduce unnecessary rework and correction work; installing high-strength building anchors after drilling and cleaning. Drilling can provide space for the installation of anchors, while cleaning the dust and debris in the holes can ensure a close bond between the anchors and the substrate. Leaving it to stand for 24 hours is to allow the adhesive or curing agent between the anchors and the substrate to have enough time to react chemically, thereby achieving the best bonding effect, so that the anchors can withstand greater tension and provide solid support for the building.

[0036] S3. Connect the steel column with the embedded bolts. Use a bridge crane to hoist the steel column and align it with the embedded bolts. After tightening the nuts, re-tighten and final tighten. Specifically, after the initial tightening of the nut, re-tightening can further increase the preload of the bolt connection. Re-tightening is usually performed after a period of time to ensure a tighter connection between the bolt and nut to prevent loosening during use. Through re-tightening, the gap or imbalance that may exist during the initial tightening can be eliminated, thereby improving the stability and safety of the entire structure. Final tightening is the final tightening step after re-tightening, and its purpose is to ensure that the bolt connection reaches the specified preload and remains stable. Final tightening usually uses a higher torque value to ensure a tight fit between the bolt and nut and prevent loosening or failure during future use.

[0037] S4, installation of steel beams. After the steel column installation review is completed, the steel beams are installed. The steel beams are hoisted symmetrically at two points. After they are installed in place, they are fixed and bolts are tightened. Specifically, in the steel beam installation steps, each steel beam is set with at least two lifting points, and the lifting rope is a lifting belt, and the installation accuracy is ensured by fine-tuning the rope. The posture and position of the steel beam may be affected by many factors, such as wind force, the accuracy of the lifting equipment, the skill level of the operator, etc. In order to ensure the installation accuracy, fine-tuning is required during the lifting process. By using the lifting belt to fine-tune the rope at at least two lifting points, the position and posture of the steel beam can be controlled more accurately. S5. Installation of steel grating. After the assembly of the main and secondary steel beams is completed, the steel grating is hoisted to the designated location and fixed with saddle clamps.

[0038] Specifically, the main function of the saddle clamp is to ensure that the steel grating can be firmly fixed on the primary and secondary steel beams after being hoisted to the designated location. This fixing method can provide sufficient stability and support to prevent the steel grating from moving or deforming during use, and can ensure the accurate installation position of the steel grating, thereby improving the stability and safety of the overall structure; in addition, the saddle clamp is also easy to install and disassemble, which is convenient for later maintenance and replacement.

[0039] In a preferred embodiment, the steel grating platform and construction method include the steps of: The first step is to prepare for construction. Select a suitable bridge crane and ensure that its working conditions are within the scope specified by technical measures. Overloading is strictly prohibited. At the same time, make good space reservations for hoisting to avoid the problem of insufficient space during hoisting and create a good working environment. During hoisting, it is strictly prohibited to walk under the hoisting parts to ensure the safety of the construction process.

[0040] The second step is to embed bolts. According to the on-site measurement of the axis of the drawing, accurately mark the location of the embedded points, and then use a drilling machine and a hole setter to drill holes. After drilling, use a hole cleaner to clean them one by one. After the holes are cleaned, report to the quality inspection department for inspection. After acceptance, install high-strength building anchor bolts and let them stand for 24 hours before proceeding to the next step of construction.

[0041] The third step is to connect the steel column with the embedded bolts. After the bolts are installed and left to stand for 24 hours, use a bridge crane to hoist the steel column so that the holes of the steel column are accurately aligned with the embedded bolts, then place small washers and tighten the nuts. After tightening the nuts for 1 hour, re-tighten them and complete the final tightening within 48 hours to ensure that the connection between the steel column and the embedded bolts is stable.

[0042] The fourth step is to install the steel beam. After the steel column installation review is completed, the steel beam installation begins. The steel beam is hoisted in a two-point symmetrical lifting method to ensure the stability of the lifting. After the steel beam is hoisted, it is slowly put into place when it is 10 cm away from the column reference surface. The construction personnel use an infrared level meter on the operating platform to correct the deviation at any time to ensure the accuracy of the installation position. After adjusting the docking, fix and tighten the bolts to ensure the stable installation of the steel beam.

[0043] The fifth step is to install the steel grille. After the main and secondary steel beams of the main plant are assembled, the steel grille is hoisted to the designated location using a bridge crane. The installers use saddle clamps to fix the steel grille on the installed steel grille platform to ensure the stability and safety of the steel grille.

[0044] The implementation principle of the embodiment of the present application is as follows: construction personnel can know exactly where to perform the pre-embedding work, thereby avoiding deviations or errors in the construction, improving the quality of construction, ensuring the structural safety and stability of the building, and also helping to improve construction efficiency and reduce unnecessary rework and correction work; installing high-strength building anchor bolts after drilling and cleaning. By drilling, space can be provided for the installation of anchor bolts, and cleaning the dust and debris in the holes can ensure the close bonding between the anchor bolts and the substrate. Leaving it to stand for 24 hours is to allow the adhesive or curing agent between the anchor bolts and the substrate to have enough time to react chemically, thereby achieving the best bonding effect, so that the anchor bolts can withstand greater tension and provide stable support for the building; the two-point symmetry keeps the steel beam stable to prevent it from swaying or tilting during the hoisting process, thereby reducing safety risks.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
