Description

Technical Field

[0001] This utility model belongs to the technical field of smoothing devices, specifically a smoothing device for civil construction. Background Technology

[0002] Civil engineering, also known as civil construction, is a general term for the science and technology of constructing various engineering facilities. It refers not only to the materials and equipment used, and the technical activities such as surveying, design, construction, maintenance, and repair, but also to the objects of engineering construction. These are various engineering facilities built on or under the ground, on land or in water, directly or indirectly serving human life, production, military, and scientific research. In the process of civil construction, a type of civil construction leveling device is often used, including trowels.

[0003] A search revealed a civil construction smoothing device, as disclosed in announcement number CN211473277U. This device includes two smoothing shovels arranged symmetrically. A connecting plate is integrally formed on the upper surface of each shovel. A fixing rod and a handle are located above the connecting plate; the fixing rod and handle are an integral structure. A locking block is fused to the end of the fixing rod opposite to the handle. A locking groove is formed inside the connecting plate. The fixing rod and the connecting plate are connected by the locking block and the locking groove. A connecting block is fused to the upper surface of the shovel near the connecting plate. A handle, connecting rod, and branch rod are provided between the two shovels. The handle, connecting rod, and branch rod are an integral structure. The branch rod is fixedly connected to the connecting block by fastening screws.

[0004] In practical use, the applicant found that the existing troweling devices for civil construction can only be used in pairs, and cannot be used in pairs or more. The practicality needs to be improved. The joints between the trowels and the connectors lack protective structures, whether used individually or in combination, allowing water and building materials (such as cement) to easily enter the joints, thus affecting later disassembly and use. In order to solve the above problems, a troweling device for civil construction is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a smoothing device for civil construction in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: A smoothing device for civil construction includes a smoothing shovel and a concave connecting plate. A vertical rod is fixedly connected to the middle of the top surface of the smoothing shovel, and a handle is fixedly connected to the top of the vertical rod. Threaded holes are opened at both ends of the handle, and a screw is threadedly connected to the threaded hole. A plug is fixedly connected to one end of the screw. A first connecting hole is opened at both ends of the upper part of the concave connecting plate. The screw can pass through the first connecting hole and be threadedly connected to the threaded hole. With the help of the plug, the concave connecting plate can be pressed and fixed to the handle. Two threaded posts are fixedly connected to both sides of the top surface of the smoothing shovel. A protective cap is threadedly connected to the outside of the threaded post. Two second connecting holes are opened at the bottom of the concave connecting plate. The threaded post can pass through the second connecting hole, and with the help of the protective cap, the bottom of the concave connecting plate can be locked and fixed to the smoothing shovel. When the concave connecting plate is not connected between the plug and the handle, an annular sealing gasket is provided at the connection between the plug and the handle, and the annular sealing gasket is sleeved on the screw. When the concave connecting plate is connected between the plug and the handle, the annular sealing gasket is provided between the concave connecting plate and the plug, and an annular sealing gasket is provided at the connection between the concave connecting plate and the handle, and the annular sealing gasket is sleeved on the screw. When the concave connecting plate is not connected to the threaded post, an annular sealing gasket three is provided at the connection between the protective cap and the smoothing shovel, and the annular sealing gasket three is sleeved on the threaded post. When the concave connecting plate is connected to the threaded post, the annular sealing gasket three is provided between the concave connecting plate and the protective cap, and an annular sealing gasket four is provided at the connection between the concave connecting plate and the smoothing shovel, and the annular sealing gasket four is sleeved on the threaded post.

[0015] The following will combine Figures 1-4 A detailed description is provided of a smoothing device for civil construction according to an embodiment of the present invention.

[0016] Example: This embodiment of the present invention provides a smoothing device for civil construction, referencing... Figures 1 to 4As shown, the device includes a trowel 1 for civil construction and a concave connecting plate 7. A vertical rod 2 is fixedly connected to the middle of the top surface of the trowel 1. A handle 3 is fixedly connected to the top of the vertical rod 2. Threaded holes 4 are opened at both ends of the handle 3. A screw 5 is threaded into the threaded hole 4. A block 6 is fixedly connected to one end of the screw 5. A connecting hole 8 is opened on both sides of the upper part of the concave connecting plate 7. The screw 5 can pass through the connecting hole 8 and be threaded into the threaded hole 4. With the help of the block 6, the concave connecting plate 7 can be pressed and fixed on the handle 3. Two threaded posts 9 are fixedly connected to both sides of the top surface of the trowel 1. A protective cap 10 is threaded onto the external thread of the threaded post 9. Two connecting holes 11 are opened at the bottom of the concave connecting plate 7. The threaded post 9 can pass through the connecting holes 11. With the help of the protective cap 10, the bottom of the concave connecting plate 7 can be locked and fixed on the trowel 1. In this structure, the operator holds the handle 3 and can use the trowel 1 to perform troweling operations in civil construction. In use, the upper end of the concave connecting plate 7 can be locked and fixed to the handle 3 by using the plug 6 and the screw 5. At the same time, one of the connecting holes 11 of the concave connecting plate 7 is inserted into the threaded post 9 of the trowel 1, and then the protective cap 10 is used to lock and fix it to the trowel 1. Similarly, the other end of the concave connecting plate 7 is locked and fixed to the handle 3 of another trowel 1, and one of the connecting holes 11 of the concave connecting plate 7 is inserted into the threaded post 9 of the trowel 1, and then the protective cap 10 is used to lock and fix it to the other trowel 1. Thus, the two trowels 1 can be connected and fixed. Then, the above operation is repeated in sequence, so that multiple trowels 1 can be connected together for use. In addition, multiple trowels 1 can be freely combined for use as needed, which makes it more practical. Furthermore, during use, the threaded hole 4 can be blocked by the plug 6 to protect the threaded hole 4. Similarly, the protective cap 10 can cover the threaded post 9 to protect the threaded post 9 and prevent the threaded hole 4 and the threaded post 9 from contacting building materials such as cement, which would affect the use.

[0017] refer to Figures 1 to 4As shown, when the concave connecting plate 7 is not connected between the plug 6 and the handle 3, an annular sealing gasket 12 is provided at the connection between the plug 6 and the handle 3, and the annular sealing gasket 12 is sleeved on the screw 5. When the concave connecting plate 7 is connected between the plug 6 and the handle 3, the annular sealing gasket 12 is placed between the concave connecting plate 7 and the plug 6, and an annular sealing gasket 23 is provided at the connection between the concave connecting plate 7 and the handle 3, and the annular sealing gasket 23 is sleeved on the screw 5. In this structure, when the plug... When block 6 blocks the threaded hole 4, the annular sealing gasket 12 seals the connection between block 6 and handle 3, preventing water and building materials from entering through the gap. Similarly, when block 6 is used to press and fix the concave connecting plate 7, the annular sealing gasket 12 seals the connection between block 6 and concave connecting plate 7, and the annular sealing gasket 2 13 seals the connection gap between concave connecting plate 7 and handle 3, preventing water and building materials from seeping into the threaded hole 4 when the trowel 1 is used.

When the concave connecting plate 7 is connected to the threaded column 9, the annular sealing gasket 3 14 is placed between the concave connecting plate 7 and the protective cap 10, and an annular sealing gasket 4 15 is provided at the connection between the concave connecting plate 7 and the trowel 1, and the annular sealing gasket 4 15 is sleeved on the threaded column 9. This structure uses the annular sealing gasket 3 14 to seal the connection between the protective cap 10 and the trowel 1, thereby preventing water and building materials from entering from the gap and affecting the threaded column 9. Similarly, when the protective cap 10 is used to press and fix the concave connecting plate 7, the annular sealing gasket 3 14 can seal the connection between the protective cap 1 and the concave connecting plate 7, and the annular sealing gasket 4 15 can seal the connection gap between the concave connecting plate 7 and the trowel 1, thereby preventing water and building materials from seeping into the threaded column 9 when the trowel 1 is connected and used.

[0019] refer to Figures 1 to 4 As shown, the block 6 has an external hexagonal columnar structure, which makes it convenient to rotate the block 6.

[0020] refer to Figures 1 to 4 As shown, the cap 10 has an external hexagonal columnar structure, which facilitates rotation.

[0021] refer to Figures 1 to 4 As shown, the handle 3 has a hollow structure. This hollow structure reduces the overall weight of the smoothing device, making it lighter.

[0022] refer to Figures 1 to 4 As shown, a soft sleeve 16 is provided on the outside of the handle 3. In this structure, the soft sleeve 16 is used to improve the grip comfort of the handle 3.

[0023] The implementation principle of a smoothing device for civil construction according to an embodiment of this application is as follows: In use, the upper end of the concave connecting plate 7 can be locked and fixed to the handle 3 by using the plug 6 and the screw 5. At the same time, one of the connecting holes 11 of the concave connecting plate 7 is inserted into the threaded post 9 of the smoothing shovel 1. Then, the protective cap 10 is used to lock and fix it to the smoothing shovel 1. Similarly, the other end of the concave connecting plate 7 is locked and fixed to the handle 3 of another smoothing shovel 1. One of the connecting holes 11 of the concave connecting plate 7 is inserted into the threaded post 9 of the smoothing shovel 1. Then, the protective cap 10 is used to lock and fix it to the other smoothing shovel 1. Thus, the two smoothing shovels 1 can be connected and fixed. Then, the above operation is repeated in sequence, so that multiple smoothing shovels 1 can be connected together for use. In addition, multiple smoothing shovels 1 can be freely combined for use as needed, which improves practicality. In use, the threaded hole 4 of the above-mentioned trowel can be blocked by the plug 6. At this time, the connection between the plug 6 and the handle 3 can be sealed by the annular sealing gasket 12, thereby preventing water and building materials from entering from the gap and thus protecting the threaded hole 4. Similarly, the protective cap 10 can be used to cover the threaded column 9, and the connection between the protective cap 10 and the trowel 1 can be sealed by the annular sealing gasket 14, thereby preventing water and building materials from entering from the gap and affecting the threaded column 9, thus protecting the threaded column 9 and preventing the threaded hole 4 and the threaded column 9 from contacting cement and other building materials and affecting the use. Furthermore, when the trowel 1 is connected and used through the concave connecting plate 7, when the concave connecting plate 7 is pressed and fixed by the plug 6, the annular sealing gasket 12 can seal the connection between the plug 6 and the concave connecting plate 7, and the annular sealing gasket 2 13 can seal the connection gap between the concave connecting plate 7 and the handle 3, thereby preventing water and building materials from seeping into the threaded hole 4 when the trowel 1 is connected and used; when the protective cap 10 is pressed and fixed by the concave connecting plate 7, the annular sealing gasket 3 14 can seal the connection between the protective cap 1 and the concave connecting plate 7, and the annular sealing gasket 4 15 can seal the connection gap between the concave connecting plate 7 and the trowel 1, thereby preventing water and building materials from seeping into the threaded post 9 when the trowel 1 is connected and used.
