Description

Technical Field

[0001] This utility model relates to the field of engineering formwork construction technology, specifically a formwork release agent application device for construction sites. Background Technology

[0002] Engineering formwork includes wooden formwork, bamboo, plywood, and steel formwork. With technological advancements, aluminum alloy formwork is now widely used in many applications. Aluminum alloy formwork, also known as aluminum alloy concrete formwork, is made primarily of aluminum alloy profiles and manufactured through machining and welding processes. It is suitable for concrete engineering and is designed according to a set modular design, consisting of panels, ribs, main profiles, flat formwork, corner formwork, and early stripping devices.

[0003] In busy construction sites, formwork serves as a crucial auxiliary tool for concrete pouring, and its processing directly impacts construction efficiency and project quality. Applying a release agent is a key step in formwork pretreatment, aiming to reduce the adhesion between concrete and the formwork, facilitating later demolding and ensuring a smooth and aesthetically pleasing structural surface. However, traditional manual brushing methods, while seemingly simple and direct, actually harbor several significant drawbacks, such as:

[0004] 1. Inefficient and costly

[0005] First, the process of manually applying release agent is extremely time-consuming. In large-scale projects, with numerous templates covering a vast area, relying on manual application of release agent to each template is not only labor-intensive but also inefficient. This not only prolongs the construction period and increases labor costs but may also hinder project progress. Furthermore, frequent manual operations also mean higher management costs and greater demands for quality monitoring, further increasing overall construction costs.

[0006] 2. Uneven coating affects quality.

[0007] Another significant drawback of manual brushing is uneven application. Due to differences in the operator's skill level, physical condition, and work attitude, the release agent is often unevenly distributed on the formwork surface, with some areas being too thick and others not completely covered. This uneven application not only affects the release effect but may also lead to defects on the concrete surface, such as sticking and peeling, seriously damaging the quality of the project.

[0008] 3. Safety hazards cannot be ignored.

[0009] Construction sites present complex environments with numerous hazards, including working at heights and operating machinery. When manually applying release agent, operators must frequently climb formwork and move through the construction area, undoubtedly increasing safety risks. Careless operation can easily lead to falls, collisions, and other accidents, posing a serious threat to personnel safety. Furthermore, release agents themselves may contain harmful chemicals, and long-term exposure or inhalation poses potential health risks. Utility Model Content

[0049] like Figures 1 to 3 As shown, a formwork release agent application device for construction sites includes a frame 1, wherein the frame 1 is equipped with a power structure, a clamping structure and a brushing structure.

[0050] The power structure includes an active roller assembly, a chain 3, and a motor 2;

[0051] The power output end of the motor 2 is connected to the chain 3, and drives the active roller group to rotate through the chain 3;

[0052] The active roller assembly can transport template 4;

[0053] The clamping structure is located above the active roller assembly and can contact the upper surface of the template 4;

[0054] The brush mold structure is located above the active roller group, and the brush mold structure can apply release agent to the template 4.

[0055] The purpose of this design is to provide a formwork release agent application device for construction sites, which includes a power structure, a clamping structure, and a brushing structure. The power structure provides power to the formwork, the clamping structure squeezes the formwork to prevent displacement or shaking during the application of the release agent, and the brushing structure replaces manual labor by mechanically applying the release agent to the formwork, significantly reducing the intensity of manual labor on site.

[0056] It should be noted that the active roller assembly typically contains multiple active rollers 10, and these active rollers 10 are all connected by a chain. In this way, the motor drives the first active roller to rotate via the chain, and then transmits this rotation via the chain, so that the entire active roller assembly rotates from the input end of the frame towards the output end of the frame, thus moving the template placed on the active roller assembly.

[0057] In this embodiment, a working groove 13 is provided on the top of the frame 1, and the pressing structure and the brushing structure are both straddling the working groove 13.

[0058] The purpose of this design is to provide the necessary working space for the clamping structure and the brushing structure through the set working slot.

[0059] In this embodiment, as Figure 5 As shown, the pressing structure includes a driven roller group, which contains multiple driven roller units. Along the conveying direction of the template 4, the driven roller units are arranged side by side.

[0060] Meanwhile, the driven roller unit includes a driven roller 5 and two limiting plates 6;

[0061] The two limiting plates 6 are respectively connected to both ends of the driven roller 5, and the limiting plates 6 are detachably connected to the opening of the working groove 13;

[0062] The driven roller 5 can contact the upper surface of the template 4;

[0063] Furthermore, a blocking strip 21 is provided on the limiting plate 6, and a vibration damping and reset structure 22 is filled between the blocking strip 21 and the end of the driven roller 5.

[0064] Meanwhile, the vibration damping and reset structure 22 is a spring.

[0065] The purpose of this design is that, in actual use, when the mold release agent is applied directly to the template through the brushing structure, the template cannot pass through the brushing structure quickly due to the lack of a front and rear clamping structure, resulting in an unsatisfactory brushing effect.

[0066] Therefore, a driven roller unit containing a driven roller and two limiting plates is set up. On the one hand, the two limiting plates are used to install the driven roller on the working groove and provide support for the driven roller. When the template is conveyed to the pressing structure via the driving roller, the driven roller can press the template from above, so that the template is flush with or slightly higher than the input end of the brushing structure. In this way, the template can pass through the brushing structure more smoothly and quickly, and is less likely to be blocked, resulting in a more ideal brushing effect.

[0067] On the other hand, the vibration damping and reset structure set on the limit plate also has the effect of damping and resetting the driven roller. When it is lifted by the template, the vibration damping and reset structure retracts. After the template passes, the vibration damping and reset structure pushes the driven roller down again to reset it. By setting the vibration damping and reset structure on the driven roller unit, the extrusion pressure can be slowly released and reset when the template is pressed, which is convenient for long-term stable use.

[0068] At the same time, Figure 5 As can be seen, there is a groove structure on the upper part of the limiting plate, which can be fastened to the opening of the working groove. In order to adapt to the needs of different templates for applying release agent, material can be filled in the groove during actual construction, so that the position of the limiting plate and the opening of the working groove moves upward relative to each other.

[0069] Furthermore, the vibration damping and reset structure used in this embodiment mainly serves to alleviate the force on the driven roller in the vertical direction and to enable the driven roller to reset after the force in the vertical direction disappears. Therefore, an elastic pad or a spring can be selected. When a spring is selected, one end of the spring is connected to or abuts against the blocking strip, which can prevent the spring from accidentally disengaging during operation.

[0070] In this embodiment, as Figure 4 As shown, a specific composition of a brush mold structure is provided, the brush mold structure including a paint bucket 12 and a paint roller 8;

[0071] The paint bucket 12 is provided with a feed inlet 7 at the top and a discharge mechanism 18 at the bottom.

[0072] The paint roller 8 is located below the discharge mechanism 18 and can contact the upper surface of the template 4.

[0073] The discharge mechanism 18 includes an inclined plate 17, a discharge port 19, and an arc-shaped surface 20;

[0074] The inclined plate 17 is located inside the paint bucket 12 and at the bottom, tilting downward toward the discharge port 19;

[0075] The discharge port 19 is located above the coating roller 8;

[0076] The arc-shaped surface 20 is located at the bottom of the paint bucket 12 and can be in contact with the paint roller 8.

[0077] The purpose of this setup is to address scenarios involving continuous formwork operations, where the formwork is continuously fed to the formwork release agent application device at the construction site by on-site workers or a formwork placement mechanism. The application structure then applies the release agent to one side of the formwork.

[0078] In actual use, the release agent is first poured into the paint bucket from the inlet. Since there is an inclined plate at the bottom of the paint bucket, the release agent is concentrated towards the outlet and flows towards the paint roller through the outlet. Since the curved surface is in contact with the paint roller and there is a certain gap in the middle, the release agent can be adsorbed on the surface of the paint roller along this gap and is then brushed onto the template.

[0079] Typically, driven roller units are installed at both the front and rear of the clamping structure during setup to reduce template movement during operation, resulting in a more ideal coating effect.

[0080] In this embodiment, a first extension plate 11 and a second extension plate 16 are also provided on both sides of the frame 1. One end of the first extension plate 11 is hinged to the feed end of the frame 1, and one end of the second extension plate 16 is hinged to the discharge end of the frame 1.

[0081] The purpose of this design is to extend the length of the entire device's input and output ends by setting the first and second extension plates, making it easier to adapt to the needs of coating templates of different lengths. In specific installation, the first and second extension plates are connected to the frame in a hinged manner. When needed, the first and second extension plates are removed from the frame and laid flat, and then the first support frame 9 is installed, with one end of the first support frame connected to the middle of the first extension plate and the other end connected to the frame, thus supporting the first extension plate. Similarly, the second support frame 15 is installed to support the second extension plate.

[0082] In this embodiment, a protective shell 14 is provided on the frame 1, and the protective shell 14 covers the chain 3.

[0083] The purpose of this design is to protect the ends of the chain and drive roller by setting up a protective shell, avoiding interference from dust and other debris, and reducing the frequency of maintenance.

[0084] Finally, it should be noted that the description of the template release agent application device in this embodiment is based more on aluminum alloy templates, but in specific application scenarios, templates made of other materials are also applicable.

[0085] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
