Description

Technical Field

[0001] The invention belongs to the technical field of building construction tools, and particularly relates to a large trowel and an integrated tool for smoothing and finishing concrete mortar. Background Art

[0002] In the current construction industry, the smoothing and finishing of concrete floors or roads is a critical and time-consuming process. This process is crucial to ensure the flatness and smoothness of the concrete surface, which directly affects the quality and service life of the project. However, this field has long been facing a technical bottleneck, that is, the smoothing and finishing operations need to be carried out in two steps, smoothing first and then finishing, which is not only inefficient, but also increases labor construction costs.

[0003] Specifically, the traditional construction method first uses a large trowel made of magnesium alloy, aluminum alloy or UPE (ultra-high molecular weight polyethylene) to initially smooth the concrete surface. Although these materials are light and easy to operate, they are not effective for subsequent finishing operations due to their relatively low hardness. Therefore, after the smoothing is completed, the construction workers need to replace the trowel with a blue steel plate or manganese steel plate to compact and finish the smoothed concrete mortar. This "smoothing first and finishing later" operation mode not only prolongs the construction period, but also increases the tediousness of tool replacement and labor costs.

[0004] In addition, the traditional construction method also has the problem of difficulty in ensuring finishing efficiency and quality. Since finishing is carried out after troweling, and the two operations use different tools, it is difficult to ensure that the finishing can completely cover and optimize the traces left by the troweling. This often leads to problems such as inconsistent finish and local roughness on the concrete surface, affecting the overall aesthetics and performance of the project.

[0005] Although the industry has made some technical attempts and improvements to address the above issues, the results are not significant. For example, there are attempts to improve the material and structure of the trowel to increase its hardness and wear resistance so that it can meet the needs of both smoothing and finishing. However, these improvements often come at the expense of the flexibility and ease of use of the trowel, and the results are not stable. Therefore, to date, the traditional "smoothing first and finishing later" operation mode still dominates. How to improve construction efficiency, reduce costs and ensure project quality is an urgent problem that needs to be solved in the current concrete floor or road construction. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a large trowel and an integrated tool for concrete mortar smoothing and finishing. The entire smoothing and finishing process does not require tool replacement, and one-time compaction, smoothing and finishing of concrete mortar ground roads and the like can be achieved.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a large trowel for both leveling and polishing concrete mortar, comprising a trowel and a light collecting plate, wherein the light collecting plate is fixedly mounted on one side of the trowel's trowel surface, the trowel's trowel surface and the light collecting plate's light collecting surface are smoothly arranged, the width of the light collecting plate is 1 / 10 to 7 / 10 of the trowel's width, and the thickness of the light collecting plate is 0.3 mm to 3 mm.

[0008] The applicant found during the research that, when the width of the trowel is constant, if the width of the light collecting plate is less than 1 / 10 of the trowel width, the light collecting efficiency will be very low; if the width of the light collecting plate is greater than 7 / 10 of the trowel width, the leveling efficiency will be very low. Both the leveling efficiency and the light collecting efficiency will lead to low overall operating efficiency. Therefore, the working area of ​​the light collecting plate and the trowel is crucial to the efficiency of the product. The present invention designs the width of the light collecting plate to be 1 / 10 to 7 / 10 of the trowel width. This range ensures the light collecting efficiency without affecting the leveling effect.

[0009] In addition, the applicant also found during the research that the thickness of the light collecting plate needs to be adapted to the wear degree of the trowel. A very thin light collecting plate will cause the light collecting plate to wear quickly and be difficult to install and fix; and increasing the thickness of the light collecting plate will increase the overall weight of the device, making it inconvenient for workers to assemble and use tools during the light collecting operation. After repeated practice, it was found that when the thickness is 0.3mm~3mm, it can ensure good toughness and durability, and the light collecting effect of the device is the best.

[0010] Preferably, the width of the light collecting plate is 1 / 4 to 1 / 2 of the width of the trowel, and the thickness of the light collecting plate is 1 to 1.5 mm.

[0011] Preferably, the width of the light collecting plate is 1 / 3 of the width of the trowel, and the thickness of the light collecting plate is 1 mm. Experiments have shown that the large trowel for smoothing and light collecting made with this size ratio has the highest working efficiency and the best light collecting effect.

[0012] Preferably, a mounting groove is provided on one side of the trowel surface, the light collecting plate is installed in the mounting groove, and the depth of the mounting groove is the same as the thickness of the light collecting plate.

[0013] Preferably, the light collecting plate is bonded to the trowel by polyamide resin glue.

[0014] Preferably, the light collecting plate is firstly glued with polyamide resin and then fixed on the trowel with the assistance of a plurality of fixing bolts, and the surface of the fixing bolts is polished.

[0015] Preferably, the trowel is made of magnesium alloy material or aluminum alloy material, the thickness of the trowel is 3 to 19 mm, and the width of the trowel is 3 to 10 inches.

[0016] Preferably, the trowel is made of UPE material, the thickness of the trowel is 3 to 30 mm, and the width of the trowel is 3 to 10 inches.

[0017] Preferably, the light collecting plate is made of high-hardness blue steel plate, manganese steel plate or spring steel plate.

[0018] A concrete mortar smoothing and finishing tool comprises the above-mentioned dual-purpose large trowel, a worm rotating bracket and a handle. The worm rotating bracket is installed on the dual-purpose large trowel, and the handle is swingably connected to the dual-purpose large trowel through the worm rotating bracket.

[0019] The present invention installs a light collecting plate on one side of the trowel, and the overall operation process is to use the trowel to smooth the concrete mortar in a pushing manner. In this process, one side of the light collecting plate is lifted up, and the trowel contacts the mortar to play a role in lifting and smoothing the mortar. Then the handle is rotated to make the smoothing side of the large trowel tilt up through the worm gear rotating bracket, and the light collecting mortar is compacted in a pulling manner. In this process, one side of the light collecting plate contacts the mortar to play a role in collecting light. The trowel does not need to change tools during the entire operation process, and one-time concrete mortar smoothing and light collecting can be achieved, and the smoothing and light collecting construction efficiency is greatly improved.

[0020] Here’s how to use it: (1) Install the light collecting plate on one side of the trowel, making sure it is firmly connected and does not fall off.

[0021] (2) During construction, workers first use a trowel to smooth the concrete mortar by pushing it. During this process, one side of the finishing board is lifted up, and the trowel contacts the mortar to lift and smooth it.

[0022] (3) Then, the worker uses the finishing board to compact and finish the smoothed concrete mortar by pulling. During this process, one side of the finishing board contacts the mortar to finish it, while the other side of the trowel is lifted.

[0023] (4) By repeating the push-pull action until the concrete surface reaches the desired flatness and glossiness, workers can continuously smooth and finish the concrete without changing tools, thus greatly improving construction efficiency.

[0024] Compared with the prior art, the above technical solution has the following beneficial effects: Through in-depth research and innovative design, the present invention proposes a new type of construction tool that effectively combines a light collecting plate with a trowel, aiming to complete the smoothing and light collecting work of concrete in one operation. The smoothing and light collecting operations of concrete are completed continuously on the same tool, which significantly improves the construction efficiency and quality. The core of the present invention is to cleverly integrate the light collecting plate on one side of the trowel, and the two processes of smoothing and light collecting can be completed in sequence through a single push-pull operation without changing tools, simplifying the operation process, reducing the construction time, reducing the tool replacement time, and ensuring the continuity and efficiency of the operation. The present invention realizes the "one push and one pull" type of efficient operation by changing the traditional operation mode. In the process of pushing, the trowel plays a major role in lifting and smoothing the concrete mortar; in the process of pulling, the light collecting plate plays a role in compacting and light collecting. This operation method simplifies the operation steps, reduces the labor intensity of workers, and improves the construction efficiency. This innovation not only significantly improves the construction efficiency, but also reduces the cost of tool replacement, and effectively ensures the flatness and finish of the concrete surface. It has broad application prospects and important practical value. The introduction of this invention not only solves the problems existing in the prior art, but also brings new technical ideas and methods to the field of concrete floor or road construction. By integrating the two processes of leveling and finishing, this invention breaks the constraints of the traditional construction mode and promotes the progress and innovation of industry technology.

[0033] Figures 1 to 7 The best embodiment of the present invention is shown below in conjunction with the attached Figures 1 to 7 The present invention is further described.

[0034] Embodiment 1 like Figure 1 As shown, a large trowel for smoothing and polishing concrete mortar of the present invention comprises a trowel 1 and a light collecting plate 2. The light collecting plate 2 is fixedly mounted on one side of the smoothing surface of the trowel 1, and the smoothing surface of the trowel 1 and the light collecting surface of the light collecting plate 2 are smoothly arranged to facilitate smoothing and polishing. The overall operation process is to use the trowel 1 to smooth the concrete mortar in a pushing manner. During this process, one side of the light collecting plate 2 is lifted up, and the trowel 1 contacts the mortar to play a smoothing role. Then the device is pulled back. During the pulling back process, the light collecting plate 2 collects the mortar. During this process, one side of the light collecting plate 2 contacts the mortar, and one side of the trowel 1 is lifted up.

[0035] like Figures 2~4 As shown, in this embodiment, a mounting groove 4 is provided on one side of the trowel 1's trowel surface, and the light collecting plate 2 is installed in the mounting groove 4. The depth of the mounting groove 4 is the same as the thickness of the light collecting plate 2. After the light collecting plate 2 is installed in the mounting groove 4, the light collecting surface of the light collecting plate 2 is flush with the trowel 1's trowel surface.

[0036] The light receiving plate 2 is glued to the trowel 1 by polyamide resin. Considering that the light receiving plate 2 must be kept flat during the light collecting process, it may not be strong enough to fix the light receiving plate 2 only by gluing. Therefore, in this embodiment, the light receiving plate 2 can be further fixed to the trowel 1 by a plurality of fixing bolts 3. A plurality of bolt holes 5 are processed on the trowel 1, and a plurality of fixing holes 6 are provided on the light receiving plate 2 corresponding to the bolt holes 5. The fixing bolts 3 pass through the fixing holes 6 and are threadedly fixed in the bolt holes 5. After the light receiving plate 2 is installed, the surface of the fixing bolts 3 is polished to ensure that the light receiving surface of the light receiving plate 2 is flat.

[0037] The light collecting plate 2 is made of high-hardness blue steel plate, manganese steel plate or spring steel plate. In this embodiment, a 50# blue steel plate is used. The trowel 1 is made of UPE material. The thickness of the trowel 1 is 3~30mm. In this embodiment, the thickness of the trowel 1 is 10mm. The thickness of the light collecting plate 2 in this embodiment is also 1mm. The width of the trowel 1 is 3~10 inches. In this embodiment, the width of the trowel 1 is 8 inches. The width of the light collecting plate 2 is 1 / 10~7 / 10 of the width of the trowel 1. In this embodiment, the width of the light collecting plate 2 is 1 / 3 of the width of the trowel 1. After repeated experiments, it was found that when the width of the light collecting plate 2 is 1 / 3 of the width of the trowel 1, the efficiency of leveling and collecting light of this device is the highest.

[0038] The following is a construction area of ​​500m 2When workers use two tools, trowel and finishing board, the construction time is: .

[0039] The following is a construction area of ​​500m 2 When the worker uses the integrated tool of the present invention, the construction time is: .

[0040] In summary, when the width of the light-collecting plate 2 of the device is 1 / 10 to 3 / 4 of the width of the trowel 1, the overall push-pull times of the device are small and the construction time is short under the same construction area, which reduces the workload of workers and improves work efficiency. Practice has shown that when the width of the light-collecting plate 2 is 1 / 3 of the width of the trowel 1, the efficiency of leveling and collecting light of the device is the highest. Compared with using only two tools, the trowel and the light-collecting plate, the workload can be reduced by half and the construction time can be reduced by about half.

The handle 10 is quickly connected to the worm rotating bracket 9 through a spring clip. The specific structure of the worm rotating bracket 9 can be referred to the Chinese utility model patent with application number CN201320197231.7, which will not be described in detail here.

[0042] The present invention installs a light collecting plate 2 on one side of the trowel 1, and installs the present invention on the handle 10 through the worm rotating bracket 9. The worker uses the trowel 1 to smooth the concrete mortar by pushing the handle 10. In this process, the worker uses the handle 10 and the worm rotating bracket 9 to lift one side of the light collecting plate 2, and the trowel 1 contacts the mortar to play a smoothing role. Then the worker pulls the handle 10 to pull the device back. During the pulling back process, the light collecting plate 2 collects the mortar. In this process, one side of the light collecting plate 2 contacts the mortar, and the worker uses the handle 10 and the worm rotating bracket 9 to lift one side of the trowel 1. The two-in-one light collecting operations are carried out simultaneously, which can improve the construction efficiency by 50%. At the same time, the consumables of the light collecting plate 2 are reduced, and the production cost is reduced.
