[0002] Considering the heavy rainfall, frequent high temperature weather and long working cycle in some parts of my country, the working environment of workers is poor when tying the steel bars of small box girders, which greatly affects the working efficiency. In order to ensure the continuity and convenience of the work in the steel bar tying area of ​​the box girder, eliminate the influence of the natural environment on the steel bar tying, and improve the comfort of the workers' operating environment, it is necessary to set up a rainproof shed in the steel bar tying area.

[0003] A Chinese patent with publication number CN103669222B discloses a prefabricated box beam combined sunshade and rainproof awning, comprising longitudinal full-length fixed angle steels welded on both the left and right sidewalks, sunshade and rainproof awning support columns movably arranged at equal intervals between the longitudinal full-length fixed angle steels and the box beam flange baffle, a supporting tripod arranged at the top of the sunshade and rainproof awning support columns, and a plug-in pipe fixedly arranged at the top of the supporting tripod; the right end of the left movable frame rod (11) and the left end of the right movable frame rod (17) are hingedly connected through a hinge shaft (16), the left end of the left movable frame rod (11) is plugged into the left plug-in pipe (8), and the right end of the right movable frame rod (17) is plugged into the right plug-in pipe (20), and a rainproof cloth (27) is movably arranged on the right end of the left movable frame rod (11) and the right movable frame rod (17). The invention adopts a plug-in combined awning support, which is easy to assemble and disassemble.

[0004] In the prior art, there are generally two solutions for rainproof canopies in the rebar binding area of ​​a precast beam yard. One is a push-pull canopy covering the rebar binding area, which can basically meet the needs of precast beam rebar construction. However, during construction, the processing area needs to frequently carry out rebar hoisting operations, and the push-pull canopy needs to be pushed and pulled manually many times, which is time-consuming and labor-intensive, and the pushing and pulling noise is relatively large. The other is a mobile canopy covering the entire rebar processing area. The rebar processing area of ​​the precast beam yard is entirely covered by a canopy, with tracks installed on both sides, and the canopy is self-propelled. Considering that after the rebar binding is completed, it is lifted and transported by a gantry crane, the fully covered rainproof canopy has a large span and height, and a larger steel specification is required to meet the use requirements. In addition, the installation and removal workload is large, and the cost investment is high.

The structure is simple and the operation is convenient, which is convenient for improving the work efficiency of the staff.

[0032] like Figures 4 to 5As shown, a wind speed sensor 10 is fixedly connected to the upper side of the square steel longitudinal beam 2; the wind speed sensor 10 is connected to the motor 7 through a controller, and the controller can control the forward rotation, reverse rotation and shutdown of the motor 7; the wind speed sensor 10 detects the external wind speed level. When the wind speed is high, the wind speed sensor 10 sends a signal to the controller, and then the controller controls the motor 7 to work, so as to retract the waterproof cloth 3 to the middle, reduce the problem of the rainproof awning being blown, pulled, deformed or even damaged by high wind speed, and improve the automation degree of the rainproof awning.

[0033] The top sides of the I-beam column 1 are rotatably connected with reels 11 through brackets, and a spring is installed between the reels 11 and the brackets; the end of the waterproof cloth 3 close to the I-beam column 1 is wound around and fixed to the surface of the reels 11; the waterproof cloth 3 is inclined, and the end of the waterproof cloth 3 close to the I-beam column 1 is higher; by setting the reels 11, when the waterproof cloth 3 is unfolded outward, the reels 11 will be pulled to rotate, and then the reels 11 will roll up the waterproof cloth 3, and when the waterproof cloth 3 is retracted to the middle, the reels 11 automatically rotate under the action of the spring and rewind the waterproof cloth 3, so that the waterproof cloth 3 is rolled up and arranged, and the subsequent use effect of the waterproof cloth 3 is improved.

[0034] Scrapers 12 are fixedly connected to both sides of the top of the I-beam column 1; the scrapers 12 are located above the waterproof cloth 3 and fit together with the waterproof cloth 3; by setting the scrapers 12 to fit together with the upper side of the waterproof cloth 3, during the process of the reel 11 rolling up the waterproof cloth 3, the scrapers 12 can further tidy up the waterproof cloth 3 and flatten the wrinkled parts of the waterproof cloth 3. At the same time, the scrapers 12 can scrape off the debris remaining on the upper side of the waterproof cloth 3, thereby improving the neatness of the waterproof cloth 3 and facilitating the reel 11 to roll up the waterproof cloth 3.

[0035] Both ends of the square steel longitudinal beam 2 are in a blocked state; a sealed shell 13 is fixedly connected to the inside of the square steel longitudinal beam 2, and the controller is installed inside the sealed shell 13; a water storage tank 14 is opened on the top of the square steel longitudinal beam 2, and the water storage tank 14 connects the inside of the square steel longitudinal beam 2 with the outside; the water storage tank 14 and the wind speed sensor 10 are not on the same plane; by setting the water storage tank 14, rainwater can enter the inside of the square steel longitudinal beam 2 through the water storage tank 14 when it rains, so as to collect the rainwater, and the collected rainwater can cool the controller inside the sealed shell 13 to avoid the problem that the temperature of the controller is too high when it is working, resulting in the controller not being able to work normally.

[0036] Water guide grooves 15 are provided on both sides of the bottom of the square steel longitudinal beam 2; the water guide grooves 15 connect the inside of the square steel longitudinal beam 2 with the outside, and the water guide grooves 15 are located above the scraper 12; a switch component is provided inside the water guide grooves 15, and the switch component can control the opening and closing of the water guide grooves 15; by setting the water guide grooves 15, under normal circumstances, the switch component closes the water guide grooves 15, so that rainwater can be collected normally inside the square steel longitudinal beam 2. When there are many stains or debris on the upper side of the waterproof cloth 3, the water guide grooves 15 can be opened by the switch component, and then the rainwater inside the square steel longitudinal beam 2 is discharged outward through the water guide grooves 15 to rinse the surface of the waterproof cloth 3, thereby removing the stains or debris on the surface of the waterproof cloth 3.

[0037] The switch assembly includes a slide groove 16 provided on the side wall of the water channel 15, and the slide groove 16 penetrates the water channel 15 and extends to the inside of the I-beam column 1; a blocking piece 17 is slidably connected to the inside of the slide groove 16; an elastic member 18 is fixedly connected between the lower end of the blocking piece 17 and the slide groove 16; a slot 19 is provided at a position of the I-beam column 1 close to the reel 11; a shifting block 20 is slidably connected to the inside of the slot 19, and the shifting block 20 is fixedly connected to the blocking piece 17; a rotating disk 21 is fixedly connected to the side surfaces of both ends of the reel 11, and a group of shifting pieces 22 are evenly distributed around the rotating disk 21; the reel 11 rotates During the process, the paddle 22 can contact the paddle block 20; when the reel 11 reels up the waterproof cloth 3, the reel 11 will synchronously drive the turntable 21 and the paddle 22 to rotate, and then the paddle 22 intermittently squeezes the paddle block 20 downward, driving the paddle block 20 to move downward, and then the paddle block 20 drives the blocking piece 17 to move downward, so that the blocking piece 17 intermittently opens the water guide groove 15. This operation enables the rainwater inside the square steel longitudinal beam 2 to be automatically discharged when the waterproof cloth 3 is recovered, thereby improving the degree of automation of the rain shelter, and cooperating with the function of the scraper 12, further improving the efficiency of cleaning the debris on the surface of the waterproof cloth 3.

[0038] Embodiment 2

[0039] like Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a group of elastic protrusions 23 are evenly distributed on the upper surface of the waterproof cloth 3; by providing the elastic protrusions 23, when the winding rod 11 rolls up the waterproof cloth 3, a frustrating effect will be generated when the elastic protrusions 23 contact and squeeze the end of the scraper 12, thereby driving the waterproof cloth 3 to shake, further shaking off the debris on the surface of the waterproof cloth 3, and improving the cleaning efficiency of the waterproof cloth 3.

[0040] A notch 24 is provided at the lower side of the end of the scraper 12 away from the I-beam column 1; a magnetic plate 25 is fixedly connected to the position near the notch 24 inside the scraper 12; the elastic protrusion 23 includes an elastic membrane 26 fixedly connected to the upper side of the waterproof cloth 3; a groove 27 is provided on the surface of the waterproof cloth 3 below the elastic membrane 26, and an elastic strip 28 is fixedly connected between the elastic membrane 26 and the groove 27; when the elastic membrane 26 is away from the scraper 12, the elastic membrane 26 is located inside the groove 27; an iron block 29 is fixedly connected to the inner side of the elastic membrane 26; under normal circumstances, debris falling on the surface of the waterproof cloth 3 may roll on its surface, and then fall from the edge of the waterproof cloth 3 The elastic protrusion 23 is easily blocked from rolling debris, resulting in more debris remaining and accumulating on the surface of the waterproof cloth 3. At this time, when the elastic membrane 26 is away from the scraper 12, the elastic membrane 26 is located inside the groove 27, which can avoid this problem and does not affect the rolling of debris on the surface of the waterproof cloth 3. When the rotating column 5 rolls up the waterproof cloth 3, the elastic membrane 26 moves to the position of the notch 24. At this time, the iron block 29 is attracted by the magnetic plate 25, thereby driving the elastic membrane 26 to bulge and act as the elastic protrusion 23, so that the elastic membrane 26 produces a setback effect when it contacts and squeezes the scraper 12, driving the waterproof cloth 3 to shake.

[0041] Working principle: the present invention is arranged in the middle of the steel bar binding area. When in use, the telescopic component can be used to control the waterproof cloth 3 to be unfolded to both sides to provide a rainproof effect. When not in use, the telescopic component can be used to control the waterproof cloth 3 to be retracted to the middle. The operation is simple and does not affect the lifting of the steel bar skeleton by the gantry crane. The cost investment is small and the space occupied is small. A rainproof working environment is created in the steel bar binding area, and the efficiency and quality of steel bar prefabrication are improved. The motor 7 drives the rotating column 5 to rotate forward or reverse, and then the rotating column 5 drives the connecting rod 1 6 to rotate, so that the angle between the connecting rod 1 6 and the connecting rod 2 8 changes, and the supporting rod 9 can be controlled to unfold outward or retract toward the middle, and then the supporting rod 9 drives the waterproof cloth 3 to unfold or retract. The structure is simple and the operation is convenient, which is convenient for improving the work efficiency of the staff. The wind speed sensor 10 detects the wind speed level outside. When the wind speed is high, the wind speed sensor 10 sends a signal to the controller, and then the controller controls the motor 7 to work, so that the waterproof cloth 3 is retracted to the middle, reducing the problem of the rainproof awning being blown and pulled out of shape or even damaged by high wind speed, and improving the automation degree of the rainproof awning; by setting the reel 11, when the waterproof cloth 3 is unfolded outward, the reel 11 will be pulled to rotate, and then the reel 11 will roll up the waterproof cloth 3. When the waterproof cloth 3 is retracted to the middle, the reel 11 automatically rotates under the action of the spring and rewinds the waterproof cloth 3, so that the waterproof cloth 3 is rolled up and arranged, and the subsequent use effect of the waterproof cloth 3 is improved; by setting the scraper 12 to fit the upper side of the waterproof cloth 3, when the reel 11 rolls up the waterproof cloth 3, the scraper 1 2 can further arrange the waterproof cloth 3 and flatten the wrinkled parts of the waterproof cloth 3. At the same time, the scraper 12 can scrape off the debris remaining on the upper side of the waterproof cloth 3, thereby improving the neatness of the waterproof cloth 3 and facilitating the reeling of the waterproof cloth 3 by the reeling column 11; by providing a water storage tank 14, when it rains, rainwater can enter the interior of the square steel longitudinal beam 2 through the water storage tank 14, so that the rainwater can be collected. The collected rainwater can cool down the controller inside the sealed shell 13 to avoid the problem that the controller cannot work normally due to excessive temperature when the controller is working; by providing a water guide groove 15, under normal circumstances, the switch component closes the water guide groove 15, so that rainwater can be collected normally inside the square steel longitudinal beam 2. When there are many stains or debris on the upper side of the waterproof cloth 3, it can be removed through the water guide groove 15. The water guide groove 15 is opened by the switch assembly, and then the rainwater inside the square steel longitudinal beam 2 is discharged outward through the water guide groove 15 to wash the surface of the waterproof cloth 3, so as to remove the stains or debris on the surface of the waterproof cloth 3; in the process of the reel 11 rolling up the waterproof cloth 3, the reel 11 will synchronously drive the turntable 21 and the paddle 22 to rotate, and then the paddle 22 intermittently presses the paddle block 20 downward, driving the paddle block 20 to move downward, and then the paddle block 20 drives the blocking piece 17 to move downward, so that the blocking piece 17 intermittently opens the water guide groove 15. This operation enables the rainwater inside the square steel longitudinal beam 2 to be automatically discharged when the waterproof cloth 3 is recovered, thereby improving the automation degree of the rainproof shed, and in conjunction with the function of the scraper 12, further improving the cleaning efficiency of the debris on the surface of the waterproof cloth 3;By providing the elastic protrusion 23, when the reel 11 is rolling up the waterproof cloth 3, the elastic protrusion 23 and the end of the scraper 12 are in contact and squeezed to produce a setback effect, thereby driving the waterproof cloth 3 to shake, further shaking off the debris on the surface of the waterproof cloth 3, and improving the cleaning efficiency of the waterproof cloth 3; under normal circumstances, the debris falling on the surface of the waterproof cloth 3 may roll on the surface and then roll off from the edge of the waterproof cloth 3, but the provision of the elastic protrusion 23 is likely to block the rolling debris, resulting in the surface of the waterproof cloth 3 being easily damaged. When the elastic film 26 is away from the scraper 12, the elastic film 26 is located inside the groove 27, which can avoid this problem and does not affect the rolling of the debris on the surface of the waterproof cloth 3. When the rotating column 5 rolls up the waterproof cloth 3, the elastic film 26 moves to the position of the notch 24. At this time, the iron block 29 will be attracted by the magnetic plate 25, and then drive the elastic film 26 to swell, acting as the elastic protrusion 23, so that the elastic film 26 and the scraper 12 are in contact and squeezed to produce a setback effect, driving the waterproof cloth 3 to shake.
