High-fall-prevention construction device for high-speed railway station canopy

Abstract

This application provides a fall-prevention construction device for a high-speed railway platform canopy, including a construction trolley, concrete formwork, and auxiliary support units. The concrete formwork includes canopy formwork and column formwork. The construction trolley and auxiliary support units are configured to support the canopy formwork. The canopy formwork includes a main formwork and drip edge formwork and beam bottom formwork located at both ends of the main formwork. Pre-embedded components are provided on the drip edge formwork. One end of each pre-embedded component is located in the concrete structure, and the other end is connected to the drip edge formwork. By fixing the canopy formwork to the concrete structure of the canopy through the pre-embedded components, the risk of formwork falling due to abnormalities in the auxiliary support units is prevented, thus eliminating the risk of workers being injured by falling debris.

Description

Technical Field

[0001] This application relates to the field of high-speed railway platform construction technology, and in particular to a high-speed railway platform canopy anti-fall construction device. Background Technology

[0002] High-speed rail canopies are structures installed on high-speed rail platforms to provide rain and sun protection for waiting passengers. Domestic high-speed rail canopies, including the canopy's expansion joints and columns, are typically constructed using concrete casting. To improve construction efficiency and reduce construction errors across different regions, specialized canopy construction trolleys can be used. To maximize the efficiency of these trolleys, they can be removed early, after the concrete of the canopy structure and columns has solidified to a certain extent but not completely, i.e., the main support structure of the canopy formwork can be removed. To ensure the stability of the canopy structure during the remaining concrete solidification process, auxiliary devices and some of the canopy formwork are needed to maintain support for the concrete. Currently, some canopy formwork relies solely on auxiliary devices for support. If these auxiliary devices malfunction or anything affects the support strength, that portion of the formwork may detach from the canopy structure and fall, potentially causing injury. Utility Model Content

[0003] This application provides a high-speed railway platform canopy anti-fall construction device, which fixes the canopy template into the concrete structure of the canopy body through pre-embedded components, avoiding the template falling due to abnormal auxiliary support units and eliminating the risk of workers being injured by falling objects.

[0004] Specifically, this application provides a high-speed railway platform canopy fall prevention construction device, including a construction trolley, a concrete formwork, and an auxiliary support unit; the concrete formwork includes a canopy formwork and a column formwork; the construction trolley and the auxiliary support unit are configured to support the canopy formwork; the canopy formwork includes a main formwork and drip edge formwork and beam bottom formwork located at both ends of the main formwork; the drip edge formwork is provided with a pre-embedded component; one end of the pre-embedded component is located in the concrete structure, and the other end is connected to the drip edge formwork.

[0005] Furthermore, the drip edge template includes a first part and a second part; the first part and the second part are spaced apart; the pre-embedded component is connected to the second part.

[0006] Furthermore, the auxiliary support unit includes side support columns and a central support column; the side support columns are configured to support the first part of the drip edge formwork; and the central support column is configured to support the bottom formwork of the beam.

[0007] Furthermore, the construction trolley includes a movable chassis and a support unit mounted on the chassis; the canopy template is mounted on the support unit.

[0008] Furthermore, the chassis includes wheels and a power unit that drives the wheels to rotate; the wheels drive the chassis to move in a first direction.

[0009] Furthermore, the construction trolley also includes a top support unit mounted on the chassis; the top support unit is configured to lift and support the load-bearing unit and the canopy template.

[0010] The beneficial effects of this application are: Before the concrete structure fully hardens, the construction trolley and part of the canopy formwork can be removed. This allows for the early release of the construction trolley to other construction positions, provided the canopy structure has sufficient structural support strength. This improves the efficiency of the construction trolley's use, thereby accelerating the overall construction progress. Furthermore, by connecting the drip edge formwork to the concrete structure through pre-embedded units, even if the auxiliary support units malfunction, the formwork will not fall due to loss of support, reducing the risk of workers being injured by falling objects.

[0017] Please combine Figures 1 to 3 This application provides a high-speed railway platform canopy fall prevention construction device, including a construction trolley 100, a concrete formwork, and an auxiliary support unit; the concrete formwork includes a canopy formwork and a column formwork; the construction trolley 100 and the auxiliary support unit are configured to support the canopy formwork; the canopy formwork includes a main formwork 200 and drip edge formwork 210 and beam bottom formwork 220 located at both ends of the main formwork 200; the drip edge formwork 210 is provided with a pre-embedded component 211; one end of the pre-embedded component 213 is located in the concrete structure, and the other end is connected to the drip edge formwork 210 plate. In actual construction, the canopy of the high-speed railway platform is constructed sequentially from one end to the other or simultaneously from both ends to the middle. To ensure overall construction efficiency, after the canopy concrete has solidified to a certain hardness (usually 75%), the support for the main formwork 200 of the canopy formwork can be removed. The stability of the canopy structure can be ensured by relying solely on the auxiliary support units to support the drip edges on both sides of the canopy concrete and the bottom of the beam in the middle, in conjunction with the concrete structure of the canopy columns. The construction trolley can then be moved to the next construction position to prepare for the construction of the next section of the canopy. This can improve the utilization efficiency of the construction trolley 100 and help to accelerate the overall construction progress of the platform canopy.

[0018] Based on the above, the drip edge template 210 in this embodiment includes a first part 211 and a second part 212; the first part 211 and the second part 212 are spaced apart; the embedded component is connected to the second part 212. The first part 211 and the second part 212 are detachably connected. Before concrete pouring, the first part 211 and the second part 212 are connected as one unit by bolts or other means to form a canopy template to ensure the canopy body is formed; after the concrete structure has solidified to 75%, the connection between the first part 211 and the second part 212 is released, the first part 211 is removed first, and the second part 212 is retained to continue to support the canopy body in conjunction with the auxiliary support unit.

[0019] Based on the above, the auxiliary support unit includes a side support column 310 and a central support column 320; the side support column 310 is configured to support the second part 212 of the drip edge template 210; the central support column 320 is configured to support the bottom template 220 of the beam.

[0020] Based on the above, the construction trolley 100 includes a movable chassis 110 and a support unit 130 installed on the chassis 110; the main template 200 of the canopy template is installed on the support unit 130.

[0021] Based on the above, the chassis 110 includes wheels and a power unit that drives the wheels to rotate; the wheels drive the chassis 110 to move in a first direction.

[0022] Based on the above, the construction trolley 100 also includes a top support unit 120 mounted on the chassis 110; the top support unit 120 is configured to lift and support the bearing unit 130 and the canopy formwork. After the construction trolley 100 travels to the construction site, the top support unit 120 lifts the bearing unit 130 and the canopy formwork mounted on the bearing unit 130 to a predetermined height and provides support, which is more convenient and provides stable and reliable support quality than traditional full-span scaffolding support; after construction is completed, the top support unit 120 drives the bearing unit 130 and the canopy formwork to descend to the initial position, facilitating the departure of the construction trolley 100.

[0023] During or before pouring concrete, embedded components 213 need to be installed on the second part 212 of the drip edge formwork 210. The embedded components 213 are typically threaded to the second part 212, and the portion exposed above the concrete structure after complete hardening can be detached or removed. Vibration and other necessary operations are also required during concrete pouring to ensure quality. After pouring, curing work including spraying and dust removal is also included.

[0024] In this embodiment, the construction trolley 100 and part of the canopy formwork are removed when the concrete (hardness) has solidified to 75%. In another embodiment, the construction trolley and part of the canopy formwork can be removed after the concrete has solidified to 80%, 85%, or become more solid.

[0025] In this embodiment, the beam bottom formwork 220 is similar to the drip edge formwork 210, also comprising two spaced-apart sections. One section is removed along with the main formwork 200 before the concrete fully hardens, while the remaining section is supported by the central support column 320 and removed after the concrete has fully hardened. In this embodiment, the portion of the canopy formwork removed before the concrete fully hardens includes the main formwork 200, the first section 211 of the drip edge formwork 210, and a portion of the beam bottom formwork 220. During removal, the connections between the first section 211 and the second section 212 of the drip edge formwork 210 and the various sections of the beam bottom formwork 220 are first disconnected, and then the main formwork 200, a portion of the drip edge formwork 210, and a portion of the beam bottom formwork 220 are lowered using the top support device 120. In another embodiment, the entire beam bottom formwork 220 is removed synchronously with the main formwork 200.

Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
