Description

Technical Field

[0001] The utility model relates to the technical field of construction devices, in particular to a telescopic awning device for a mobile formwork. Background Art

[0002] In the field of construction, the in-situ casting construction of double-track box girders at high altitude is one of the common and important links. Traditional construction methods mostly use mobile formworks as the support system, which can move along the track and complete the pouring of box girders. However, the existing mobile formwork systems usually lack effective sunshade and rain protection functions, which has an adverse impact on construction efficiency.

[0003] Especially under the high temperature conditions in summer, the strong direct sunlight will not only cause the concrete to lose water too quickly, affecting its quality, but also increase the risk of heatstroke for the operators, forcing the workers to suspend work at noon to avoid health problems. In addition, the arrival of rain brings more challenges to construction. Due to the lack of proper rain protection facilities, the rain will directly fall on the surface of the uncured concrete, resulting in the forced interruption of construction, which not only prolongs the construction period of the box girder, but also reduces the labor efficiency of the workers.

[0030] The present utility model provides a retractable canopy device for a mobile formwork, aiming to solve the problem of lack of efficient and convenient sunshade and rain protection measures in the construction of mobile formworks in the prior art, so as to improve the construction environment and work efficiency. The following combines Figures 1-9 Describe the specific implementation manner of the retractable canopy device of the mobile formwork of the present utility model.

[0031] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the retractable awning device of the mobile formwork includes: rails 10, two rails 10 are arranged in parallel and at intervals above the main beam of the mobile formwork; the awning main frame 20, which includes a plurality of cross-section support structures and a telescopic frame assembly, and the telescopic frame assembly is connected between adjacent cross-section support structures; the cross-section support structure at the tail end of the awning main frame 20 is fixed to the main beam, and a traveling mechanism is arranged between the cross-section support structure at the head end of the awning main frame 20 and the rail 10 to drive the head end of the awning main frame 20 to move along the rail 10; the cross-section support structure includes a truss 21 and two columns 22 arranged below the truss 21, and a sliding mechanism adapted to the rail 10 is arranged at the bottom end of the column 22. By covering a flexible awning cover on the awning main frame 20, a retractable awning device that can be automatically deployed or folded can be realized.

[0032] Specifically, two rails 10 are arranged in parallel and at intervals above the main beam of the mobile formwork, providing a stable support and moving path for the awning main frame 20. The awning main frame 20 includes a plurality of cross-section support structures and a telescopic frame assembly, and the telescopic frame assembly is connected between adjacent cross-section support structures, allowing the length of the awning to change. The cross-section support structure specifically includes a truss 21 and columns 22. The columns 22 are used to support the truss 21, and the truss 21 provides a stable top structure foundation for the awning. The sliding mechanism at the bottom end of the column 22 is adapted to the rail 10, ensuring the smoothness and smoothness of the awning during movement. The traveling mechanism arranged at the head end of the awning main frame 20 can drive the awning main frame 20 to move along the rail 10.

[0033] As Figure 3 shown, according to a retractable awning device of a mobile formwork provided by the present utility model, the truss 21 includes a skeleton cross beam 23 and a skeleton arc beam 24, as well as a skeleton vertical brace 25 and a skeleton diagonal brace 26 arranged between the skeleton cross beam 23 and the skeleton arc beam 24. Among them, the skeleton cross beam 23 is the cross beam structure at the bottom of the truss 21, the skeleton arc beam 24 is the structure at the top of the truss 21 for supporting the awning, the skeleton vertical brace 25 is supported between the skeleton cross beam 23 and the skeleton arc beam 24, and the skeleton diagonal brace 26 forms a triangular stable support structure between adjacent skeleton vertical braces 25. Through the design of the above truss 21 structure, not only a stable support frame is provided, but also the stability and strength of the entire awning device are ensured.

[0034] According to a telescopic awning device of a mobile formwork provided by the present utility model, the top end of the column 22 is connected to the skeleton cross beam 23, and a diagonal brace rod 27 is arranged between the column 22 and the skeleton cross beam 23. The diagonal brace rod 27 arranged between the column 22 and the skeleton cross beam 23 is obliquely connected between the column 22 and the skeleton cross beam 23 at a certain angle, forming a triangular structure, utilizing the principle of geometric stability and increasing the stability of the structure.

[0035] Preferably, the length of the skeleton cross beam 23 is longer than the distance between two columns 22 of the same cross-section support structure, and an additional space can be formed outside the columns 22. The diagonal brace rod 27 is arranged on the part of the skeleton cross beam 23 that extends beyond the columns 22, that is, near both ends of the skeleton cross beam 23, so that an additional support structure can be formed at the thinner edge of the skeleton cross beam 23.

[0036] As Figure 3 shown, according to a telescopic awning device of a mobile formwork provided by the present utility model, the telescopic frame assembly includes a vertical telescopic frame 31 arranged between adjacent columns 22, and a top telescopic frame 32 arranged between adjacent trusses 21. Among them, the vertical telescopic frame 31 is arranged between adjacent columns 22, used to support and connect adjacent columns 22, and can also be telescopic to adapt to awning requirements of different lengths. The top telescopic frame 32 is arranged between adjacent trusses 21, used to connect adjacent truss 21 structures, and also has a telescopic function, and can adjust the width of the awning according to needs. Through the vertical telescopic frame 31 arranged between adjacent columns 22 and the top telescopic frame 32 arranged between adjacent trusses 21, the telescopic awning device provided by the present utility model can not only adjust its coverage range according to needs, but also ensure the stability and safety of the awning during the telescopic process.

[0037] As Figure 4 shown, according to a telescopic awning device of a mobile formwork provided by the present utility model, the telescopic frame assembly includes two connecting rods 33 arranged crosswise, and the middle parts of the two connecting rods 33 are hinged and matched with each other. In the vertical telescopic frame 31, one end of the connecting rod 33 is hinged to the column 22, and the other end is slidably matched with the adjacent column 22; in the top telescopic frame 32, one end of the connecting rod 33 is hinged to the truss 21, and the other end is slidably matched with the adjacent truss 21. The design of the crosswise arranged connecting rods 33 enables the telescopic frame assembly to be extended or contracted according to needs, so as to adjust the length or width of the awning.

[0038] As Figure 6As shown in the figure, the upper and lower parts of the figure are respectively the side schematic diagrams of the retractable awning device in the unfolded state and the folded state. Among them, the vertical telescopic frame 31 is arranged between the columns 22 of the adjacent cross-section support structures. During the process of unfolding or folding the awning, the angle between the two cross-arranged connecting rods 33 changes, and the sliding ends of the connecting rods 33 slide up and down on the adjacent columns 22. Similarly, as Figure 7 shown, it is the plan schematic diagram of the retractable awning device in the unfolded state; as Figure 8 shown, it is the plan schematic diagram of the retractable awning device in the folded state. Among them, the top telescopic frame 32 is arranged between the trusses 21 of the adjacent cross-section support structures, preferably arranged between the skeleton crossbeams 23. During the process of unfolding or folding the awning, the angle between the two cross-arranged connecting rods 33 changes, and the sliding ends of the connecting rods 33 slide left and right on the adjacent skeleton crossbeams 23. The sliding ends of the connecting rods 33 can be matched with the columns 22 or the skeleton crossbeams 23 in the way of a slide rail. Preferably, the sliding ends of the connecting rods 33 can be provided with a ring structure, and this ring structure is sleeved on the columns 22 or the skeleton crossbeams 23 to enable sliding.

[0039] As Figure 5 shown, according to a retractable awning device of a mobile formwork provided by the present invention, the sliding mechanism includes a concave pulley 41 arranged at the bottom end of the column 22; the track 10 includes a guide tube 11 adapted to the outer peripheral concave surface of the concave pulley. The cooperation between the concave pulley 41 and the guide tube 11 enables the awning to slide smoothly during movement, reduces shaking, and ensures the stability and safety during the movement process.

[0040] Furthermore, according to a retractable awning device of a mobile formwork provided by the present invention, the track 10 includes a load-bearing steel beam 12; the load-bearing steel beam 12 is arranged on the main beam of the mobile formwork, and the guide tube 11 is arranged on the top of the load-bearing steel beam 12. The load-bearing steel beam 12 is arranged on the main beam of the mobile formwork to bear the weight of the awning and its load. The guide tube 11 is arranged on the top of the load-bearing steel beam 12 and is adapted to the outer peripheral concave surface of the concave pulley 41 to ensure the smoothness and stability during the sliding process. The use of the load-bearing steel beam 12 improves the bearing capacity of the track 10 and ensures the safety of the awning and its load during the movement process.

[0041] According to a retractable awning device of a mobile formwork provided by the present utility model, the sliding mechanism includes a C-shaped protection. The C-shaped protection part includes guard plates 42 arranged on both sides of the concave pulley, and limit members 43 extending from the guard plates 42 towards the load-bearing steel beam 12. The cross-sectional shape of the load-bearing steel beam 12 is an I-shaped. When the sliding mechanism is engaged with the track 10, the guard plates 42 are located on both sides of the load-bearing steel beam 12, and the limit members 43 are located in the concave structures on both sides of the load-bearing steel beam 12. The use of the C-shaped protection structure improves the stability and safety of the sliding mechanism during movement. The design of the guard plates 42 and the limit members 43 ensures the smoothness during the sliding process and reduces shaking. In particular, the design of the limit members 43 can prevent the sliding mechanism from disengaging from the track 10 during movement, improving the overall safety of the system. By providing the C-shaped protection structure, including the guard plates 42 and the limit members 43, and using it in cooperation with the load-bearing steel beam 12, the retractable awning device provided by the present utility model not only improves the stability and safety of the sliding mechanism during movement, but also simplifies the maintenance work, providing an efficient and reliable sunshade and rain protection solution for construction workers.

[0042] As Figure 6 shown, according to a retractable awning device of a mobile formwork provided by the present utility model, the traveling mechanism includes a driver 51 arranged at the head end of the awning main frame 20 and a driving wheel 52 in transmission cooperation with the driver 51. When the sliding mechanism is engaged with the track 10, the driving wheel 52 presses against the track 10 at the same time. The driver 51 arranged at the head end of the awning main frame 20 is responsible for generating driving force. The driving wheel 52 in transmission cooperation with the driver 51 contacts the track 10. When the driver 51 works, the driving wheel 52 rotates to push the awning to move along the track 10. The driver 51 can be a motor or a servo motor, etc.

[0043] Preferably, the above-mentioned traveling mechanism is arranged between the first cross-section support structure and the second cross-section support structure at the head end of the awning main frame 20 to facilitate installation and ensure that the traveling mechanism is always within the coverage range of the awning. Correspondingly, there is no need to set up a telescopic frame assembly between the first cross-section support structure and the second cross-section support structure, and a cross bar can be used instead.

[0044] As Figure 9As shown, a telescopic awning device for a mobile formwork according to the present utility model includes two sets of awning main frames 20. The tails of the two sets of awning main frames 20 are connected and share the same fixed point, and the heads of the two sets of awning main frames 20 face in opposite directions. Each set of awning main frames 20 has its own components such as a track 10 and a telescopic mechanism. When the head of one set of awning main frames 20 moves in one direction, the head of the other set moves in the opposite direction. By providing two sets of awning main frames 20 with opposite-facing heads, the coverage area of sunshading and rain protection can be effectively expanded to meet the construction requirements of a larger area, and it allows construction workers to independently control the movement of each set of awning main frames 20 as needed, or move both sets simultaneously to cover more construction areas.
