Abstract
Description
Technical field
[0001] The present utility model belongs to the field of spraying and maintenance technology for hollow pillars and relates in particular to a spraying and maintenance device for hollow pillars. Background technology
[0002] Thin-walled hollow piers can typically save 40% to 60% of concrete compared to solid gravity piers. Previously, the construction of thin-walled hollow piers was quite complex and also very material-intensive in terms of steel consumption, which is why they were rarely used. It wasn't until the 1970s, with the gradual development of new techniques such as the mechanical connection of reinforcement sleeves and the folding of steel formwork, that the difficulties regarding high labor costs, material waste, poor quality, slow construction speed, and working at great heights could be efficiently overcome. As a result, thin-walled hollow piers found widespread use in bridge construction.
[0003] Maintaining hollow columns is a crucial step after the column structure is completed, especially for tall columns, where safety and maintenance pose particular challenges. The conventional method currently involves wrapping the column structure with a tarp or installing a bucket of water at the top of the column for maintenance purposes. A crane is used to lift workers to a specific height to wrap the hollow column with tarp. However, this conventional method of using a bucket of water does not ensure uniform maintenance on all sides, which can lead to certain areas being neglected and cracks developing in the concrete.
[0004] To address the problems mentioned above, we have proposed a spraying and maintenance device for hollow pillars. Content of the utility model
[0005] The purpose of this utility model is to solve the problem of conventional maintenance using buckets of water, which does not guarantee that every surface is treated uniformly. This can lead to some areas being neglected and potentially causing cracks in the concrete. A spray and maintenance device for hollow columns is proposed to address this issue.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: Spraying and maintenance device for hollow columns, comprising a base frame, wherein the base frame is fixedly connected to the wall by means of bolts, wherein several cross plates are fixedly attached to the base frame, wherein a base plate is fixedly mounted on the cross plates, wherein the cross plates are evenly distributed, wherein a support plate is fixedly mounted to the wall, wherein a boundary frame is fixedly mounted on the base plate, wherein a threaded rod is rotatably attached to the boundary frame, wherein a motor is fixedly mounted to the boundary frame, wherein the output end of the motor is fixedly connected to the threaded rod, wherein a water box is slidably mounted on the threaded rod, wherein several spray heads are fixedly mounted on the water box.
[0007] Preferably, the base frame is designed as a right-angled triangle, with each of the two legs being firmly connected to the wall and the cross plate.
[0008] Preferably, several connecting rods are firmly mounted in the base frame, each of these connecting rods being firmly connected to the base frame by means of bolts.
[0009] Preferably, a guide rod is fixedly mounted in the boundary frame, with the guide rod being arranged parallel to the threaded rod.
[0010] Preferably, the water box is designed in an arc shape extending outwards, with several spray heads evenly distributed on the water box.
[0011] Preferably, a connecting plate is permanently mounted on the water box, with a water inlet provided on the connecting plate.
[0012] In summary, the technical effects and advantages of the present utility model are as follows: A limiting frame attached to the base plate of the spraying and maintenance device for hollow columns, and a motor firmly mounted on the limiting frame, ensure that the base frame of the device is fixed to the hollow column. A pre-prepared bucket of water is then connected to the water inlet of the water box via a hose. The liquid in the bucket is sprayed through the spray heads of the water box to irrigate the hollow column. When the motor is started, the threaded rod attached to the output end of the motor rotates, thereby moving the water box, which is screwed to the threaded rod, up and down to ensure more even irrigation of the hollow column. Illustration of the attached figures Fig. Figure 1 shows a schematic structural representation of the overall structure of the present utility model; Fig. Figure 2 shows a schematic structural representation of the boundary framework of the present utility model; Fig. Figure 3 shows a schematic structural top view of the present utility model; Fig. Figure 4 shows a schematic structural representation of the water box of the present utility model.

[0014] The preferred embodiments are described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a subset of the embodiments of the utility model and not all existing embodiments.
[0015] The present utility model discloses a spraying and maintenance device for hollow columns, designed to solve the problem of conventional maintenance using buckets of water. This method does not guarantee uniform maintenance of all surfaces, easily leading to insufficient moisture in certain areas and consequently to cracks in the concrete. A limiting frame mounted on the base plate and a motor rigidly attached to the limiting frame secure the device's base frame to the hollow column. A pre-filled bucket of water is then connected via a hose to the water inlet of the water box. The liquid in the bucket is sprayed through the water box's spray heads to moisten the hollow column.Starting the motor then causes the threaded rod attached to the motor's output end to rotate, moving the water box, which is screwed to the threaded rod, up and down to ensure more even watering of the hollow pillar.
[0016] To better understand the above-mentioned technical solutions, the technical solutions are explained in detail below in conjunction with the drawings of the description and the specific embodiments.

[0018] Referring to Fig. In sections 1-3, the base frame 1 is designed as a right-angled triangle, with each of its two legs rigidly connected to the wall and the cross plate 2, respectively. The base frame 1 is arranged in a triangular shape to utilize the stability of the triangle. This makes the base frame 1 more rigid when connected to and supported by the side wall of the hollow column, less susceptible to vibrations and displacements, and ensures the safety of the workers during operation.
[0019] Referring to Fig. Several connecting rods 10 are firmly mounted in the base frame 1, each of these connecting rods 10 being firmly connected to the base frame 1 by means of bolts.

The water inlet 12 mounted on the water box 8 ensures that the water supply is provided via pipes and enters the water box 8 through the water inlet 12, in order to subsequently irrigate the hollow pillar through the spray heads 9 located on the water box 8. Working principle:
[0025] A limiting frame 5, attached to the base plate 3, and a motor 7, fixed to the limiting frame 5, ensure that the base frame 1 of the device is fixed to the hollow column. A pre-prepared bucket of water is then connected via a hose to the water inlet 12 of the water box 8. The liquid in the bucket is sprayed through the spray heads 9 of the water box 8 to irrigate the sides of the hollow column. Starting the motor 7 then rotates the threaded rod 6 attached to the output end of the motor 7, thereby moving the water box 8, which is screwed to the threaded rod 6, up and down to ensure more even irrigation of the hollow column.
