Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel bar rust prevention technology, specifically a rust-preventive liquid spraying device for the surface of steel bars used in construction. Background Technology
[0002] In the construction industry, steel bars, as a core building material, are susceptible to environmental corrosion. To improve durability, rust inhibitors (such as water-based or solvent-based anti-corrosion coatings) are typically sprayed onto the steel bar surface to form a protective layer. Currently, the widely used rust inhibitor spraying process requires the steel bar to be left horizontally for a period of time (usually several minutes to tens of minutes) after spraying to allow the rust inhibitor to level out and initially cure. During this process, excess rust inhibitor drips continuously down the steel bar surface due to gravity, leading to two major problems:
[0003] First, there is environmental pollution: dripping rust inhibitor contaminates the work site floor, forming oily residues that are difficult to clean, increasing cleaning costs and violating environmental protection construction requirements. Second, there is material waste: according to statistics, dripping losses account for 15%-30% of the total amount of rust inhibitor used, significantly increasing construction costs, especially in large-scale projects. Utility Model Content
[0004] This utility model provides a rust-preventive liquid spraying device for the surface of steel bars used in construction, in order to solve the defects in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A rust-preventive spraying device for steel reinforcement in construction includes a base plate supported by columns. Vertically extending vertical plates are vertically connected to both sides of the top surface of the base plate. The top surface of each vertical plate has a downward-concave arc-shaped groove. The arc-shaped grooves on the two vertical plates are aligned horizontally. Multiple arc-shaped grooves are arranged in the longitudinal direction of the vertical plates, extending to the sides of the vertical plates. The top surface of the base plate is concave towards the center, and several guide channels are formed along its curvature. These guide channels are located directly below the steel reinforcement. A water collection trough, perpendicular to and connected to the guide channels, is longitudinally formed at the center of the concave surface. The water collection trough is connected to a discharge pipe, and a receiving bucket is located below the discharge pipe.
[0007] In use, the reinforcing bars are placed on the corresponding arc-shaped grooves. Since the arc-shaped grooves are set on the vertical plates, which are distributed on both sides, they can support the reinforcing bars while exposing most of them. Then, rust-inhibiting liquid is sprayed onto the reinforcing bars. After spraying and allowing them to settle, the dripping rust-inhibiting liquid will fall onto the guide channel and flow into the collection tank. In the collection tank, it will enter the discharge pipe and finally enter the feed bucket. This not only achieves the recovery of the rust-inhibiting liquid but also avoids contaminating the ground with the rust-inhibiting liquid.
[0008] Preferably, a filter screen is installed inside the feed pipe, and the feed pipe is detachably and fixedly installed on the base plate. The filter screen can prevent falling impurities from entering the rust inhibitor, thereby ensuring the purity of the rust inhibitor.
[0009] Preferably, the water collection tank has a through hole with an internal thread, and the discharge pipe has an external thread and is connected to it by the thread. The threaded connection of the discharge pipe allows the discharge pipe to be disassembled for cleaning of the filter screen and the discharge pipe.
[0010] Preferably, a crossbar is fixedly installed on the top surface of the base plate along its transverse direction. One vertical plate is vertically connected to the crossbar, and the other vertical plate slides and locks along the crossbar. The crossbar and the reinforcing bars are staggered in the longitudinal direction. One vertical plate can move and lock, thereby changing the distance between the two vertical plates, which in turn can support reinforcing bars of different lengths and increase the range of use of the equipment.
[0011] Preferably, the crossbar has a groove in which a slider slides. Another vertical plate is fixedly connected to the slider. The slider has a threaded hole in which a lead screw is threaded. A fixed plate is vertically connected to the crossbar, and a blind hole is formed on the fixed plate. The lead screw passes through the blind hole and is rotatably connected to the fixed plate via a bearing within the blind hole. Rotating the lead screw causes the slider to move, which in turn moves the corresponding vertical plate, thus achieving the movement and locking of the vertical plate.
[0012] Preferably, the base plate is provided with a cover, one end of which is fixedly connected to an electric telescopic rod, and the other end of the electric telescopic rod is fixedly set on the side of the base plate. The cover can play a protective role, ensuring that no foreign objects fall into the guide channel when the plate is stationary, thus preventing the rust inhibitor from being contaminated.
[0013] The beneficial effects of this utility model are as follows: the use of this application can achieve the collection of rust-preventive liquid through the base plate, avoiding ground pollution caused by rust-preventive liquid falling on the ground. At the same time, the rust-preventive liquid can be collected by the guide channel, water collection tank, discharge pipe and receiving bucket, ensuring its recycling and reuse, thereby saving resources to a certain extent.

[0020] A rust-preventive spraying device for steel reinforcement in construction, such as Figure 1 and Figure 2 As shown. It includes a base plate 1, supported by columns. Vertically extending vertical plates 2 are vertically connected to both sides of the top surface of the base plate 1. The top surface of each vertical plate 2 has a downward-concave arc-shaped groove. The arc-shaped grooves on the two vertical plates 2 are aligned in the horizontal direction. Multiple arc-shaped grooves are arranged in the longitudinal direction of the vertical plates 2, extending to the sides of the vertical plates 2. The top surface of the base plate 1 is a concave surface, with several guide channels 4 formed along its curvature. The guide channels 4 are located directly below the reinforcing bars 3. A water collection trough 5, perpendicular to and connected to the guide channels 4, is longitudinally formed at the center of the concave surface. Fixed plates are fixedly connected to both ends of the water collection trough 5. The water collection trough 5 is connected to a discharge pipe 6, and a receiving bucket 7 is located below the discharge pipe 6.
[0021] This application mainly addresses the problem of collecting rust inhibitors. As for rust inhibitor spraying, that is existing technology and will not be described in this application.
[0022] In use, the reinforcing bar 3 is placed on the corresponding arc-shaped groove. Since the arc-shaped groove is set on the vertical plate 2, which is distributed on both sides, it can support the reinforcing bar 3 and expose most of the reinforcing bar 3. Then, the reinforcing bar 3 is sprayed with rust-preventive liquid. When the spraying is completed and the bar is left to stand, the dripping rust-preventive liquid will fall onto the guide groove 4 and enter the water collection tank 5 along the guide groove 4. Then, it enters the discharge pipe 6 in the water collection tank 5 and finally enters the feed bucket. This not only realizes the recovery of the rust-preventive liquid but also avoids the rust-preventive liquid from polluting the ground.
[0023] The feed pipe 6 is equipped with a filter screen, and the feed pipe 6 is detachably and fixedly mounted on the base plate 1. The filter screen can prevent falling impurities from entering the rust inhibitor, thereby ensuring the purity of the rust inhibitor.
[0024] The water collection tank 5 has a through hole with an internal thread, and the discharge pipe 6 has an external thread and is connected to it by the thread. The discharge pipe 6 can be disassembled to clean the filter screen and the discharge pipe 6.
[0025] A horizontal bar 8 is fixedly installed on the top surface of the base plate 1 along its transverse direction. One vertical plate 2 is vertically connected to the horizontal bar 8, and the other vertical plate 2 slides and locks along the horizontal bar 8. The horizontal bar 8 and the reinforcing bars 3 are staggered in the longitudinal direction. One vertical plate 2 can move and lock, thereby changing the distance between the two vertical plates 2, and thus supporting reinforcing bars 3 of different lengths, increasing the range of use of the equipment.
[0026] The crossbar 8 has a groove in which a slider slides. Another vertical plate 2 is fixedly connected to the slider. The slider has a threaded hole in which a lead screw 9 is threadedly fitted. A fixed plate is vertically connected to the crossbar 8. The fixed plate has a blind hole. The lead screw 9 passes through the blind hole and is rotatably connected to the fixed plate via a bearing. Rotating the lead screw 9 causes the slider to move, which in turn moves the corresponding vertical plate 2, thus achieving the movement and locking of the vertical plate 2.
[0027] The base plate 1 is provided with a cover 10, and one end of the cover 10 is fixedly connected to an electric telescopic rod 11. The other end of the electric telescopic rod 11 is fixedly set on the side of the base plate 1. The cover 10 can play a protective role, ensuring that no foreign objects fall into the guide groove 4 when it is stationary, and avoiding contamination of the rust inhibitor.
[0028] The use of this application enables the collection of rust-preventive liquid through the base plate 1, avoiding ground pollution caused by the rust-preventive liquid falling on the ground. At the same time, the rust-preventive liquid can be collected through the guide channel 4, the water collection tank 5, the discharge pipe 6 and the receiving bucket 7, ensuring its recycling and reuse, thereby saving resources to a certain extent.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
