Description

Technical Field

[0001] This utility model relates to the field of concrete smoothing, specifically a tool for smoothing and finishing the surface of concrete floor slabs. Background Technology

[0002] After the concrete is poured, before it sets, the surface of the concrete structure needs to be smoothed to ensure that the concrete surface is flat. The finishing and smoothing of the concrete floor slab surface is a key process to ensure that the floor slab is flat, dense and beautiful. Choosing the right tools is the basis for ensuring the quality of finishing and smoothing.

[0003] Among the existing finishing and smoothing tools, a type called a large trowel is commonly seen on construction sites due to its advantages of not requiring electricity and being easy to carry. On construction sites, when finishing and smoothing concrete floor slabs, since the pouring time of each floor of the building is close, the subsequent finishing and smoothing work is usually carried out by multiple people at multiple points at the same time. However, the number of people on the construction site is limited and needs to be allocated to the work surfaces of each process. Sometimes the number of trowels prepared exceeds the number of trowels, resulting in some trowels being idle. In order to make full use of the idle trowels, we have proposed a finishing and smoothing tool for concrete floor slabs. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for smoothing and finishing the surface of concrete floor slabs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a tool for smoothing and finishing concrete floor slab surfaces includes a trowel. A connecting mechanism is provided at the middle of the two short sides of the upper surface of the trowel. The connecting mechanism includes a U-shaped box, which is fixedly connected to the upper surface of the trowel. The opening of the U-shaped box faces away from the inside of the trowel. A hook plate is vertically inserted into the inside of the U-shaped box. A cover plate is slidably connected to the upper side of the hook plate inside the U-shaped box. An extension mechanism is also provided at the middle of the upper surface of the trowel.

[0006] Furthermore, the outer wall of the U-shaped box has an outlet that matches the size of one end of the cover.

[0007] Furthermore: the extension mechanism includes a support plate, which is fixedly installed on the top of the trowel, and a fixed support is fixedly installed in the middle of the upper surface of the support plate.

[0008] Furthermore: a connecting support is detachably installed on the top of the fixed support, and a tie rod is rotatably connected to the upper side of the connecting support.

[0009] Furthermore: a spherical shaft is rotatably connected to the middle of the upper surface of the connecting support, an inner spherical shaft is rotatably connected to the top of the spherical shaft, and the lower end of the tie rod is fixedly connected to the top of the inner spherical shaft.

[0010] Furthermore, the interior of the U-shaped box has several slots that are adapted to the size of the lower end of the hook plate.

[0011] Furthermore: The U-shaped box has a limiting groove on the upper side of the hook plate, and the cover plate has a locking block that matches the size of the limiting groove at the inner end near the hook plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, when there are fewer workers than tools available for finishing and smoothing operations, the idle tools can be assembled together through a connecting mechanism. The combination of multiple sets of trowels expands the smoothing surface, making the smoothing operation more efficient. A spherical shaft is rotatably connected to the middle of the upper surface of the pull rod, and an inner spherical shaft is rotatably connected to the top of the spherical shaft. The lower end of the pull rod is fixedly connected to the top of the inner spherical shaft. The spherical shaft and the inner spherical shaft facilitate the large-scale movement of the pull rod, making it convenient to carry out finishing and smoothing operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5The figure shows a preferred embodiment of the present invention, a tool for smoothing and finishing the surface of a concrete floor slab, including a trowel 1. A connecting mechanism 2 is provided in the middle of the two short sides of the upper surface of the trowel 1. The connecting mechanism 2 includes a U-shaped box 3. The U-shaped box 3 is fixedly connected to the upper surface of the trowel 1. The opening direction of the U-shaped box 3 is facing away from the inside of the trowel 1. A hook plate 4 is vertically inserted into the inside of the U-shaped box 3. A cover plate 5 is slidably connected to the upper side of the hook plate 4 inside the U-shaped box 3. An extension mechanism 6 is also provided in the middle of the upper surface of the trowel 1.

[0017] To facilitate changing the position of the hook plate 4 inside the U-shaped box 3, an outlet with a size matching one end of the cover plate 5 is provided on the upper side of the outer wall of the U-shaped box 3. After the cover plate 5 is pushed out, it is convenient to adjust the hook plate 4.

[0018] The extension mechanism 6 includes a support plate 7, which is fixedly installed on the top of the trowel 1. A fixed support 8 is fixedly installed on the middle of the upper surface of the support plate 7 to make the structure more stable.

[0019] Specifically, a connecting support 9 is detachably installed on the top of the fixed support 8, and a tie rod 10 is rotatably connected to the upper side of the connecting support 9, such as... Figure 4 As shown in the figure, the connecting support 9 can be threaded to the top of the fixed support 8, or it can be installed on the top of the fixed support 8 by bolts.

[0020] The upper surface of the connecting support 9 is rotatably connected to a spherical shaft 11, and the top of the spherical shaft 11 is rotatably connected to an inner spherical shaft 12. The lower end of the pull rod 10 is fixedly connected to the top of the inner spherical shaft 12. The arrangement of the spherical shaft 11 and the inner spherical shaft 12 facilitates the large-scale movement of the pull rod 10 and makes it convenient to carry out finishing and smoothing operations.

[0021] Understandably, in order to allow the cover plate 5 to be inserted into different positions within the U-shaped box 3, the interior of the U-shaped box 3 is provided with several slots 13 that are adapted to the dimensions of the lower end of the hook plate 4. Figure 3 In the middle, part of the slot 13 position is obscured by the hook plate 4 and is not shown.

[0022] To prevent the cover plate 5 from detaching from the U-shaped box 3, a limiting groove 14 is provided inside the U-shaped box 3 on the upper side of the hook plate 4. The cover plate 5 is provided with a locking block that matches the size of the limiting groove 14 at one end near the inner side of the hook plate 4, thereby preventing the cover plate 5 from being lost.

[0023] In this embodiment, when the number of finishing and smoothing workers is less than the number of finishing and smoothing tools, the idle tools can be connected together by the connecting mechanism 2. The state of the two tools when connected is as follows: Figure 1As shown, the combination of two trowels 1 expands the troweling surface, making the troweling operation more efficient. It should be noted that when more than three sets of tools are combined, it is inconvenient to work because too many pull rods 10 cannot be held. In this case, the lower side of the excess pull rods 10 can be connected to the support 9 and removed from the fixed support 8. Specifically, regarding the connection method of the working tools via the connecting mechanism 2, first gently press the short sides of the two tools together. Then, push the cover plate 5 to open the inside of the U-shaped box 3. It should be noted that the height of the cover plate 5 is higher than the height of the support plate 7 without obstruction. After the cover plate 5 is moved, the insertion position of the hook plate 4 can be changed, adjusted as follows: Figure 3 At the indicated position, the cover plate 5 is then pushed back to restrict the vertical movement of the hook plate 4, ensuring a stable connection between the two working tools.

[0024] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
