Description

Technical Field

[0001] The utility model relates to a building exterior wall maintenance device. Background Art

[0002] After the concrete pouring of the building exterior wall is completed, timely maintenance is required in the later stage to improve the molding quality of the concrete building wall. The later maintenance is generally within 12 hours after the pouring is completed, and the concrete can be covered or moisturized. This is mainly because the concrete begins to solidify in 8 hours, so after the initial setting, maintenance can begin. The curing time is generally not less than 7 days. If other admixtures or minerals are added to the concrete, the curing time needs to be extended to two weeks. The maintenance mainly includes watering and spraying plastic film.

[0003] At present, the concrete exterior wall is mostly maintained by sprinkling. During the existing exterior wall maintenance, workers stand on the ground or on the external scaffolding and spray the entire building wall with a handheld water pipe. The spacing and uniformity of the spraying are poor due to the influence of human factors, and there is a problem of spray leakage.

DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Refer to Figure 1-Figure 7As shown, the utility model provides a building exterior wall maintenance device. When the building exterior wall 1 is being constructed, a scaffold 2 needs to be built. When the building exterior wall 1 is poured, the building exterior wall 1 needs to be maintained. The maintenance device uses the original height of the scaffold 2 to maintain the building exterior wall 1. There is a certain distance between the scaffold 2 and the building exterior wall 1 for the maintenance component 3 to move. The maintenance component 3 includes a spray component 4 and a connecting component 5. The connecting component 5 includes a fixed limit frame 51 and a movable bracket 52 connected to the fixed limit frame 51. The movable bracket 52 is equipped with a winding member 6, which is used to drive the movable bracket 52 to move vertically along the length of the fixed limiting frame 51. The winding member 6 is arranged at the upper end of the scaffolding 2, and the winding member 6 includes a traction rope, a roller and a driving mechanism (the winding member 6 is a prior art and will not be described in detail here) to realize the winding of the traction rope and thus realize the height of the movable bracket 52 at the fixed limiting frame 51, thereby realizing the spraying maintenance of the exterior walls 1 at different heights. The spray member 4 is arranged on the movable bracket 52 and moves back and forth horizontally with the movable bracket 52.

[0027] Refer to Figure 2 , Figure 3As shown, the fixed limit frame 51 includes a rectangular frame formed by splicing and enclosing multiple splicing rods 511, which are connected at the corners by corner pieces. The size of the rectangular frame is adjusted according to the area of ​​the building exterior wall 1 that needs to be sprayed and maintained, thereby ensuring that the spray part 4 sprays fully and avoiding uneven manual spraying and leakage. The splicing rod 511 extends toward the end face of the scaffolding 2 with an adjustment bayonet 512, and the adjustment bayonet 512 includes a fixed plate and an adjustment plate. The adjustment plate is adjusted by a threaded rod to change the distance between the adjustment plate and the fixed plate, thereby clamping the fixed limit frame 51 on the scaffolding 2 to avoid loosening. The movable bracket 52 includes a first rod 521 and a second rod 522 formed by splicing multiple limit rods 523. Both ends of the first rod 521 and the second rod 522 are connected by a connecting rod. The first rod 521 and the second rod 522 are arranged in parallel. The first rod 521 and the second rod 522 are movably connected to the splicing rod 511 through a clamp and the shaking of the movable bracket 52 is prevented by the setting of the clamp. The position of the first rod 521 and the second rod 522 is then limited by the winding member 6. The end surface of the limit rod 523 facing the building exterior wall 1 is provided with a groove 524 along the length of the limit rod 523, and the upper and lower end surfaces of the groove 524 are spaced apart along the length direction with a first locking groove 525 and a second locking groove 525. The spraying member 4 includes an L-shaped base 41 and a movable seat 42 slidably connected to the L-shaped base 41. A water collecting chamber 411 is provided in the L-shaped base 41. A leak plate 412 is provided on the upper end surface of the water collecting chamber 411. A drainage pipe 413 is connected to the bottom of the water collecting chamber 411. Since splashing water will be generated when the spraying member 4 sprays water onto the building exterior wall 1, the present application collects the splashing water through the water collecting chamber 411, and then discharges it back to the water supply system through the drainage pipe 413, so as to realize water recycling and avoid the problem of serious waste of water resources. A cavity 421 is provided inside the movable seat 42. A pump body 422 is provided inside the cavity 421. One end of the pump body 422 is connected to the external water supply system through a water supply pipe, and the other end is connected to a nozzle 423 through a water supply pipe. The nozzle 423 can adjust the spraying angle, and the nozzle 423 sprays the building exterior wall 1. The L-shaped base 41 and the movable seat 42 are connected via a telescopic driving member 43, and the telescopic driving member 43 is driven by a hydraulic telescopic rod or a telescopic cylinder. The movable seat 42 is provided with a first sliding locking member 44 corresponding to the groove 524 and the locking groove 525 of the first rod 521, and the L-shaped base 41 is provided with a second sliding locking member 45 corresponding to the groove 524 and the locking groove 525 of the second rod 522. The first sliding locking member 44, the second sliding locking member 45 and the telescopic driving member 43 are all equipped with a controller, and the controller controls the opening and closing of the sliding locking member and the telescopic driving member 43.

[0028] For details, refer to Figure 6 , Figure 7As shown, the first sliding locking member 44 and the second sliding locking member 45 both include a fixed block 7 fixedly connected to the L-shaped base 41 or the movable seat 42, and the upper and lower end surfaces of the fixed block 7 corresponding to the limit rod 523 are provided with an arc plate 8, and the arc plate 8 can be clamped on the limit rod 523. A slider 9 extends from the center of the fixed block 7 toward the groove 524. Through the arrangement of the slider 9 and the arc plate 8, the L-shaped base 41 and the movable seat 42 can be restricted from rotating along the limit rod 523, and can only move laterally along the length of the limit rod 523. The slider 9 is provided with a concave hole corresponding to the locking groove 525, and the locking block 10 is connected to the spring in the concave hole. The cavity is provided with a pushing member 11, and the pushing member 11 is used to push the locking block 10 to lock with the locking groove 525. The pushing member 11 includes a pushing rod 111 arranged in the cavity. The end face of the cavity close to the L-shaped base 41 or the movable seat 42 is embedded with a pass electromagnet 112, and the end face of the pushing rod 111 facing the pass electromagnet 112 is provided with an iron block. When the pass electromagnet 112 is energized, the pushing rod 111 moves laterally toward the pass electromagnet 112. The pushing rod 111 is shaped like a horizontal funnel. The pushing rod 111 has an inclined surface, which fits with the inclined surface of the locking block 10, which will prompt the locking block 10 to be pushed outward toward the concave hole and stuck in the locking groove 525, thereby limiting the lateral movement of the movable seat 42 or the L-shaped base 41, and then driving the unrestricted movable seat 42 or the L-shaped base 41 to move laterally.

[0029] The working method is as follows: the fixed limit frame 51 can be mounted on the scaffold 2 through the adjustable bayonet, and then the movable bracket 52 is set on the fixed limit frame 51 through the clamp, and the movable bracket 52 is placed in the most suitable position by retracting the winding member 6. The spraying sequence can be moved upward from the bottom of the building outer wall 1 or from the top to the bottom according to the actual situation. The L-shaped base 41 and the movable seat 42 are slidably connected with the first rod 521 and the second rod 522 through the first sliding locking member 44 and the second sliding locking member 45. The movable seat 42 is connected by a hydraulic telescopic rod or a telescopic cylinder. In the initial state, the second sliding locking member 45 locks the L-shaped base 41 on the locking groove 525 of the second rod 522, and the first sliding locking member 44 locks the movable base on the locking groove 525 of the first rod 521. The locking grooves 525 of the first rod 521 are distributed at intervals according to the moving distance of the movable base, and the locking grooves 525 of the second rod 522 are distributed at intervals according to the moving distance of the L-shaped base 41. When the corresponding position of the nozzle 423 on the movable base is sprayed and needs to be moved horizontally to spray the unsprayed area, the first sliding locking member 44 corresponding to the movable base is powered off by the controller, and the second sliding locking member 45 continues to limit the position of the L-shaped base 41 to be fixed. Then the hydraulic telescopic rod or telescopic cylinder is started to extend. After the movable base is moved to the corresponding position, the first sliding locking member 44 is powered on and locked with the locking groove 525. During the spraying process of the nozzle 423 of the movable base, the second sliding locking member 45 is powered off by the controller. Since the movable base is fixed at this time, the hydraulic telescopic rod or telescopic cylinder is started to extend. The retractable rod or telescopic cylinder drives the L-shaped base 41 to move laterally, and moves to the corresponding position, and the second sliding locking member 45 is energized and locked. At this time, the nozzle 423 has finished spraying the area, and then the above steps are repeated until the lateral spraying is completed. After the lateral spraying is completed, the winding member 6 is started, and the movable bracket 52 synchronously drives the spray member 4 to move up or down to the corresponding position. The spray member 4 starts a new round of lateral spraying until the spraying and maintenance of the entire building exterior wall 1 is completed, realizing intelligent spraying, without manual spraying, and the maintenance device is suitable for high-rise buildings.
