DETAILED DESCRIPTION

[0021] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0022] The present invention provides a bridge deck paving construction platform, see Figure 1 and Figure 6 The bridge deck construction platform includes: an intermediate platform and two end platforms 2, and the two end platforms 2 are detachably connected to the two ends of the intermediate platform in the length direction; wherein the intermediate platform includes one or more standard platform units 1, and the adjacent standard platform units 1 are detachably connected; the bottom of the end platform 2 is provided with a walking wheel 3, and the walking wheel 3 is located at the end of the end platform 2 away from the intermediate platform.

[0023] When the bridge deck paving construction platform is used, according to the span of the bridge deck to be constructed, an appropriate number of standard platform units 1 are connected between the two end platforms 2, so that the two ends of the assembled bridge deck paving construction platform can be located on the bottom surface of both sides of the bridge deck, and supported above the bridge deck by the running wheels 3 provided at the bottom of the end platforms 2. Figure 1 As shown, the middle platform has only one standard platform unit 1, such as Figure 6 As shown, the middle platform includes two standard platform units 1 connected together to meet the span of the bridge deck to be constructed. Construction workers can stand on the bridge deck paving construction platform and level the concrete of the bridge deck from one side of the platform, thereby ensuring the construction quality of the bridge deck concrete when leveling a large area. Construction workers standing on the bridge deck paving construction platform to perform construction work can also reduce fatigue during construction and improve safety during work.

[0024] Specifically, the standard platform unit 1 and the end platform 2 both include a platform frame 11 and a panel 12. The platform frame 11 is a rectangular frame structure. The panel 12 is a rectangular plate-like structure that matches the platform frame 11. The panel 12 is fixedly connected to the top of the platform frame 11. In specific implementation, the length of the end platform 2 can be consistent with the length of the standard platform unit 1 to facilitate batch production of the platform frame 11 and the panel 12. The length of the end platform 2 can also be shorter or longer than the length of the standard platform unit 1, which is not limited in this embodiment.

[0025] See also Figure 3 and Figure 5 The platform frame 11 includes two longitudinal beams 111 and a plurality of transverse beams 112. The two longitudinal beams 111 are spaced apart by a preset distance and are arranged in parallel. The plurality of transverse beams 112 are vertically connected between the two longitudinal beams 111. The top surfaces of the longitudinal beams 111 and the transverse beams 112 are flush. Furthermore, an oblique support rod 113 is arranged between the longitudinal beams 111 and the transverse beams 112. In this embodiment, the longitudinal beam 111 and the cross beam 112 are both made of channel steel, and the oblique support rod 113 is made of equilateral angle steel. The oblique support rod 113 is obliquely connected between the longitudinal beam 111 and the cross beam 112 to form a triangular stable support structure to enhance the stability of the connection between the longitudinal beam 111 and the cross beam 112; the top surfaces of the longitudinal beam 111 and the cross beam 112 are flush, and the top surfaces of the oblique support rod 113 are also flush with the top surfaces of the longitudinal beam 111 and the cross beam 112 to form sufficient support for the panel 12 and enable the panel 12 to be flat after laying. In specific implementation, the panel 12 can be connected and fixed to the top of the platform frame 11 by welding or riveting.

[0026] Furthermore, the panel 12 is an anti-skid steel plate. The anti-skid steel plate can be a lentil-shaped or diamond-shaped anti-skid steel plate to prevent construction workers from slipping when standing on the bridge deck paving construction platform for construction work. It is understandable that the panel 12 can also be made of ordinary steel plates, and a plastic anti-skid mat is laid on the panel 12 to improve the anti-skid property of the bridge deck paving construction platform.

[0027] Furthermore, lifting rings (not shown in the figure) can be provided on both sides of the width direction of the platform frame 11 to facilitate the lifting of the bridge deck paving construction platform by lifting equipment when it is assembled or disassembled. The lifting rings can be made of bent steel bars or steel pipes and fixed to the platform frame 11 by welding.

[0028] See also Figure 2 and Figure 4, the standard platform unit 1 is provided with two middle handrail frames 13, and the end platform 2 is provided with two end handrail frames 21, and the distance between the two middle handrail frames 13 on the standard platform unit 1 matches the distance between the two end handrail frames 21 on the end platform 2. Specifically, the two middle handrail frames 13 are arranged at both ends of the width direction of the standard platform unit 1, the length of the two middle handrail frames 13 is consistent with the length of the standard platform unit 1, and the two ends of the middle handrail frames 13 are flush with the two ends of the platform frame 11 of the standard platform unit 1; the two end handrail frames 21 are arranged at both ends of the width direction of the end platform 2, and the end surfaces of the two end handrail frames 21 facing the standard platform unit 1 are flush with the end surfaces of the platform frame 11 of the corresponding end platform 2. In this way, when the platform frame 11 of the end platform 2 is connected to the platform frame 11 of the standard platform unit 1, the end handrail frames 21 on the end platform 2 can also be aligned and connected with the middle handrail frames 13 on the standard platform unit 1. The middle handrail frame 13 and the end handrail frames 21 can block both sides of the bridge deck paving construction platform to improve the safety of construction workers when standing.

[0029] Furthermore, the middle handrail frame 13 includes a horizontal handrail rod 131 and a plurality of first vertical rods 132, the horizontal handrail rod 131 is parallel to the top surface of the standard platform unit 1, and the plurality of first vertical rods 132 are connected between the standard platform unit 1 and the horizontal handrail rod 131; the end handrail frame 21 includes an inclined handrail rod 211 and a plurality of second vertical rods 212, the inclined handrail rod 211 is inclinedly arranged on the top surface of the end platform 2, and the plurality of second vertical rods 212 are connected between the end platform 2 and the inclined handrail rod. In this embodiment, the horizontal handrail rod 131 and the inclined handrail rod 211 are made of channel steel, and the first vertical rod 132 and the second vertical rod 212 are made of square steel pipes. The upper and lower ends of the first vertical rod 132 and the second vertical rod 212 are respectively provided with connecting end plates, the upper and lower ends of the first vertical rod 132 are respectively connected to the horizontal handrail rod 131 and the standard platform unit 1 by bolts, and the upper and lower ends of the second vertical rod 212 are respectively connected to the inclined handrail rod 211 and the end platform 2 by bolts. By designing the parts of the middle handrail frame 13 and the end handrail frame 21 to be detachably connected, storage and transportation can be facilitated to reduce the occupied space during storage and transportation.

[0030] Furthermore, the end platform 2 and the standard platform unit 1, as well as the adjacent standard platform units 1, are connected by a plurality of high-strength bolts; the end handrail frame 21 and the middle handrail frame 13, as well as the adjacent middle handrail frames 13, are connected by a plurality of bolts. Specifically, the end of the platform frame 11 of the end platform 2 and the end of the platform frame 11 of the standard platform unit 1 are provided with platform connection end plates, which are connected to the end of the longitudinal beam 111 of the platform frame 11 by welding, and bolt holes are provided on the platform connection end plates, and the adjacent standard platform units 1 and the standard platform unit 1 and the end platform 2 units are connected by high-strength bolts passing through the platform connection end plates. Similarly, both ends of the horizontal handrail rod 131 of the middle handrail frame 13 and the ends of the inclined handrail rod 211 of the end handrail frame 21 are respectively provided with handrail connecting end plates, and the handrail connecting end plates are connected to the ends of the horizontal handrail rod 131 and the end handrail rod by welding. Bolt holes are also provided on the handrail connecting end plates, and adjacent middle handrail frames 13 and middle handrail frames 13 and end handrail frames 21 are connected by bolts passing through the handrail connecting end plates.

[0031] Furthermore, the travel wheel 3 is a universal wheel, which is connected to the bottom of the end platform 2 by bolts; a braking device is provided on the universal wheel. Figure 4 and Figure 5 As shown, two universal wheels are arranged at the bottom of each end platform 2, and the two universal wheels are distributed on both sides of the width direction of the end platform 2. The universal wheels can realize 360-degree rotation, and can realize the longitudinal and lateral movement of the bridge deck paving construction platform. A friction strip is arranged on the braking device to realize the friction with the universal wheel body to achieve the braking effect. As a preferred embodiment, the walking wheel 3 can be installed at the bottom of the end platform 2 through a lifting support rod (not shown in the figure), and the lifting support rod may include an outer tube and an inner tube sleeved together, the outer tube and the inner tube are connected to the bottom of the end platform 2, the inner tube is sleeved in the outer tube, and the walking wheel 3 is arranged at the bottom of the inner tube, and multiple groups of jacks are correspondingly arranged on the outer tube and the inner tube. After the inner tube and the outer tube are telescopically adjusted to an appropriate height, the inner tube and the outer tube are fixed by inserting a pin into a group of jacks corresponding to the inner tube and the outer tube. The lifting support rod can adjust the overall height of the bridge deck paving construction platform to adapt to bridge decks of different heights.
