Description

Technical Field

[0001] This utility model relates to the field of wall maintenance technology, and in particular to a shear wall spray maintenance device. Background Technology

[0002] Shear walls, as a type of structural wall, primarily bear horizontal loads caused by wind or earthquakes, while also supporting vertical loads (gravity). They are an important load-bearing structure in buildings. This wall design effectively prevents structural shear failure, improving the stability and safety of buildings.

[0003] Regular maintenance of shear walls ensures they maintain their design strength and crack resistance over long-term use, preventing structural damage caused by factors such as temperature and humidity changes. Maintenance measures include, but are not limited to, regular inspections, waterproofing, anti-corrosion treatment, and spray curing. Spray curing, as the most common maintenance method, maintains a suitable temperature for the wall (concrete), preventing shrinkage cracks. Furthermore, the hardening process of concrete generates a large amount of heat of hydration, leading to significant temperature differences between the inside and outside, which can easily cause expansion and cracking. Spray curing can reduce this temperature difference and prevent the formation of temperature cracks.

[0004] Utility model patent CN220725824U discloses a building concrete curing device capable of spray curing of walls. During operation, a third motor adjusts the angle of the spray pipe (allowing the spray nozzles to face diagonally upwards or downwards), a first motor, threaded screw, movable plate, and mounting bracket adjust the height of the spray pipe, and a second motor, first threaded rod, first slider, and mounting bracket adjust the translation of the spray pipe. While the spray pipe in this building concrete curing device offers significant flexibility, enabling spray curing over a wider area, this is achieved by increasing the number of electrically powered components, the overall structural complexity, and the difficulty of control.

[0005] Utility model patent CN214658983U discloses a concrete curing device for construction, capable of water-based curing of walls. In its operation, a water-receiving container is first saturated with water, then its end face is brought into contact with the wall. A roller then rolls and presses the container, forcing the absorbed water onto the wall surface, thus completing the water-based curing. While this concrete curing device achieves uniform curing and prevents water splashing, its curing area per cycle is limited by the size of the container's end face, resulting in low efficiency. Furthermore, it must be placed very close to the wall to ensure proper contact; it cannot be used if there are obstacles below the wall or other situations making proximity inconvenient.

[0006] Utility model patent CN211818240U discloses a maintenance device for repairing cracks in basement shear walls, enabling spray maintenance of the wall. During operation, a drive motor moves the first slider and its fixed nozzle, along with the second slider and its fixed nozzle, synchronously towards or away from each other, achieving translational adjustment of the two nozzles. By loosening the locking knob, the slide moves vertically along the frame. When it reaches a suitable position, tightening the locking knob locks the slide, allowing manual adjustment of the two nozzles indirectly mounted on the slide. Loosening the quick-clamping component releases the gear lock, and then the swing plate rotates to a suitable position. Pressing the quick-clamping component again relocks the gear, locking the entire plate, thus enabling manual tilt adjustment of the two nozzles indirectly mounted on the plate. Although the aforementioned maintenance device for repairing cracks in basement shear walls can achieve precise maintenance of cracks at any angle, it is not suitable for spraying maintenance of large-area walls. First, it only has two spray points (two nozzles), resulting in a small water output area. Second, the raising and lowering of the two nozzles is manually operated, which is inefficient, leading to very low efficiency when spraying large-area walls.

[0007] It is evident that existing wall water supply and maintenance devices cannot simultaneously meet the requirements of simple structure, easy control, efficient operation, precise maintenance of cracks at any angle, and efficient maintenance of large-area walls. Utility Model Content

[0026] To facilitate understanding of the precast block sealing structure for external wall tie rod holes provided in this application embodiment, its application scenario is first explained. Shear walls, as a type of structural wall, primarily bear horizontal loads caused by wind or earthquakes, while also supporting vertical loads (gravity), making them a crucial load-bearing structure in buildings. This wall design effectively prevents structural shear failure, improving the stability and safety of the building. Regular maintenance of shear walls ensures they maintain their design strength and crack resistance over long-term use, preventing structural damage due to temperature and humidity changes. Maintenance measures include, but are not limited to, regular inspections, waterproofing, anti-corrosion treatment, and spray curing. Spray curing, as the most common maintenance measure, maintains a suitable temperature for the wall (concrete), preventing shrinkage cracks. Furthermore, the hardening process of concrete generates a large amount of heat of hydration, leading to significant temperature differences between the inside and outside, which can easily cause expansion and cracks. Spray curing can reduce this temperature difference, preventing the formation of temperature cracks. Existing wall water supply and maintenance devices cannot simultaneously meet the requirements of simple structure, easy control, efficient operation, precise maintenance of cracks at any angle, and efficient maintenance of large-area walls.

[0027] Example 1:

[0028] like Figure 1-4 As shown, the shear wall spray curing device includes a spraying mechanism and an actuation mechanism.

[0029] The spraying mechanism includes a water storage tank 11, a water pump 12, a hose 13, a buffer tank 14, a T-shaped pipe 15, and a spray head 16 connected in sequence.

The front end of the hose 13 is connected to the outlet of the water pump 12 and is located in the inner cavity A111 of the water storage tank 11. The rear end of the hose 132 extends upward through the outlet A on the water storage tank 11 and is connected to the inlet 142 of the buffer tank 14. The T-shaped pipe 15 includes a rigid pipe A151 and a rigid pipe B152 that are interconnected. The T-shaped pipe 15 is T-shaped as a whole, and the rigid pipes A151 and B152 are arranged perpendicular to each other. The rigid pipe B152 has multiple water outlets arranged in a straight line, and each water outlet is connected to a spray head 16. The free end of the rigid pipe A151 extends into the inner cavity B141 of the buffer tank 14 through the outlet B143 of the buffer tank 14. The free end of the rigid pipe A151 is rotatably connected to the outlet B143 of the buffer tank 14. When the T-shaped pipe 15 rotates, the plane swept by the rigid pipe B152 is a vertical plane.

[0031] The actuating mechanism includes a lifting assembly and a tilting assembly. The lifting assembly is located between the water storage tank 11 and the buffer tank 14, and is used to drive the buffer tank 14 to move vertically up and down. The tilting assembly is located between the water storage tank 11 and the rigid pipe A151, and is used to lock or unlock the T-shaped pipe 15, thereby adjusting the tilt angle of the rigid pipe B152. When the T-shaped pipe 15 is locked, the T-shaped pipe 15 and the buffer tank 14 are relatively fixed. When the T-shaped pipe 15 is unlocked, the rigid pipe A152 can rotate in a sealed manner relative to the buffer tank 14.

[0032] The lifting assembly includes a base 21, a motor 22, a lead screw 23, guide rods 24, and a slider 25. The base 21 is fixedly installed on the upper end of the water storage tank 11, and has an inner cavity C211 inside. The motor 22 is fixedly installed on the lower end of the inner cavity C211 of the base 21, and its shaft extends vertically upward. The lead screw 23 is arranged vertically, and its lower end is fixedly connected to the shaft of the motor 22 through a coupling.

Multiple guide rods 24 are arranged parallel to the lead screw and located in the inner cavity C211 of the base 21. The lower end of the guide rod 24 is fixedly connected to the lower end of the inner cavity C211 of the base 21, and the upper end of the guide rod 24 is fixedly connected to the top of the inner cavity C211 of the base 21. The slider 25 is provided with a threaded hole for engaging the lead screw 23 and a light hole for engaging the guide rod 24. The number of light holes is the same as the number of guide rods 24 and they correspond one-to-one. The slider 25 is screwed to the lead screw 23 through the threaded hole and slides to the guide rod 24 through the light hole. The slider 25 and the buffer box 14 are integrally formed.

[0033] The tilting assembly includes arc-shaped plates 31 and spring pins 32. Multiple arc-shaped plates 31 are evenly welded in a ring within the inner cavity B141 of the buffer box 14. A rigid tube A151 extends between three arc-shaped plates 31 and forms rolling contact with the convex surfaces of the three arc-shaped plates 31. The spring pin 32 is fixedly installed on the upper outer side of the buffer box 14. The spring pin 32 has a handle and a pin end at its two ends, respectively. The handle is located outside the buffer box 14, and the pin end extends into the interior of the buffer box 14. Pulling the handle of the spring pin 32 causes the pin end to exit the pin hole of the rigid tube A151; releasing the handle causes the pin end to re-enter the pin hole 1511 of the rigid tube A151. When the pin end of the spring pin 32 extends into any pin hole 1511 on the rigid tube A151, the T-shaped tube 15 is locked; when the pin end of the spring pin 32 exits from any pin hole 1511 on the rigid tube A151, the T-shaped tube 15 is unlocked.

[0034] Preferably, the rigid pipe A151 located in the inner cavity B141 of the buffer tank 14 has a plurality of pin holes 1511 evenly distributed in an annular pattern. The outer circular surface of the rigid pipe A151 and the outlet B143 of the buffer tank 14 are rotated and sealed by bearings and sealing rings. The rigid pipe A151 is positioned in the axial direction so that the rigid pipe A151 is kept at the depth of insertion into the inner cavity B141 of the buffer tank 14.

[0035] Preferably, the number of curved plates 31 is 3.

[0036] Preferably, the number of water outlet holes on the rigid pipe B152 is 3-8.

[0037] Preferably, the number of pin holes 1511 is 6-36. When the number of pin holes 1511 is 6, the angle between two adjacent pin holes 1511 is 360 / 6=60°. Similarly, when the number of pin holes 1511 is 36, the angle between two adjacent pin holes 1511 is 360 / 36=10°.

[0038] Preferably, two casters 17 and two support legs 18 are respectively provided on the two opposite edges at the lower end of the water tank 11. When the water tank 11 is placed on the ground, the two support legs 18 and the two casters 17 work together to keep the water tank 11 stable and stationary.

[0039] Preferably, the side wall of the water storage tank 11 is provided with a transparent window arranged in a vertical strip shape, and the material of the transparent window is glass or plastic.

[0040] The method of using this utility model is as follows:

[0041] The following preparations should be made before spray curing the wall:

[0042] a. Move the shear wall spray curing device to the vicinity of the wall and arrange it facing the wall (since all the spray heads 16 are facing the same direction, simply make all the spray heads 16 face the wall).

[0043] b. Adjust the T-tube 15 to a horizontal position by operating the spring pin 32 (the specific operation is to lift the handle of the spring pin 32 so that the pin end of the spring pin 32 exits the pin hole of the rigid tube A151, and then manually rotate the T-tube 15 to a horizontal position. At this time, the handle of the spring pin 32 is aligned with a pin hole 1511 on the rigid tube A151. Then release the handle of the spring pin 32 so that the pin end of the spring pin 32 moves downward under the action of the elastic force and inserts into the corresponding pin hole 1511 on the rigid tube A151, thus realizing the operation of adjusting the T-tube 15 to a horizontal position).

[0044] c. Operate the lifting assembly to raise the T-shaped tube 15 to the top or lower it to the bottom (specifically, start the motor 22, and the power of the motor 22 is transmitted to the slider 25 through the lead screw, driving the slider 25 to move up or down along the lead screw 23, thereby driving the buffer box 14 and the T-shaped tube 15 to move up or down).

[0045] The procedure for spray curing walls is as follows:

[0046] Two operations are performed simultaneously: 1. The water pump 12 is started, causing water in the water storage tank 11 to pass sequentially through the water pump 12, hose 13, and buffer tank 14 into the T-shaped pipe 15, and finally spray mist-like water from each spray head 16 simultaneously; 2. The lifting assembly is operated to raise the T-shaped pipe 15 to its highest or lowest position (if the initial position of the T-shaped pipe 15 is at its lowest, it is raised to its highest; if the initial position of the T-shaped pipe 15 is at its highest, it is lowered to its lowest). Through the above two operations, spray curing of the wall within the rectangular area is achieved.
