[0002] With the rapid development of the construction industry, due to its good mechanical properties, durability and plasticity, concrete structures are widely used in various building structures. From residential buildings, commercial complexes to large-scale infrastructure, they all show their unique advantages. Concrete structures can not only meet the diverse architectural design requirements, but also have the characteristics of beautiful appearance and easy shaping, becoming an indispensable part of modern buildings. During the construction process of concrete structures, the construction quality of the surface layer is directly related to the overall aesthetics and durability of the building. Although the construction process of the concrete structure surface layer is relatively simple, as one of the key steps, the technical requirements and operation difficulties of surface layer finishing cannot be ignored.

[0016] Furthermore, the handle mounting assembly includes:

[0017] A handle mounting seat, which is located directly above the support vertical plate, and the handle mounting seat is rotatably connected to the handle rod;

[0018] Connecting ear plates, which are located on both sides of the support vertical plate and are fixedly connected to the handle mounting seat;

[0019] And, a hinge axis, which passes through the connecting ear plate and the supporting vertical plate along the length direction of the smearing plate, and hinges the supporting vertical plate with the connecting ear plate.

[0025] Compared with the prior art, the utility model has at least the following beneficial effects:

[0026] A surface finishing and troweling tool for concrete structures provided by the present utility model has a handle mounting assembly hinged to a support assembly, and the hinge axis is parallel to the length direction of the trowel plate, enabling flexible adjustment of the height angle of the handle rod.

Detailed implementation mode

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Combined with Figures 1 to 5 As shown, the embodiment of the present utility model provides a screeding and pressing tool for the surface layer of a concrete structure, aiming to solve the problems of limited screeding and pressing range and low construction efficiency. The screeding and pressing tool includes a screeding plate 1, a support assembly 2, a handle mounting assembly 3, a handle rod 4, a first chain 5 and a second chain 6. The support assembly is fixedly connected to the middle position of the upper end surface of the screeding plate 1. The handle mounting assembly 3 is hinged to the support assembly 2, and the hinge axis is parallel to the length direction of the screeding plate 1. The handle rod 4 is rotatably connected to the handle mounting assembly 3, and the rotation axis is orthogonally cross-shaped with the projection of the hinge axis on the horizontal plane. The first chain 5 is located on one side of the handle rod 4 and close to one side of the screeding plate 1. One end of the first chain 5 is connected to the handle rod 4, and the other end is connected to the support assembly 2. The second chain 6 is located on the other side of the handle rod 4 and close to the other side of the screeding plate 1. One end of the second chain 6 is connected to the handle rod 4, and the other end is connected to the support assembly 2.

[0037] Specifically, the handle mounting assembly 3 is hinged to the support assembly 2, and the hinge axis is parallel to the length direction of the trowel plate 1, enabling flexible adjustment of the height angle of the handle rod 4. During operation, the operator can adjust the angle of the handle rod 4 as needed. The handle rod 4 is rotatably connected to the handle mounting assembly 3, and the rotation axis is orthogonally cross-shaped with the projection of the hinge axis on the horizontal plane. A first chain 5 and a second chain 6 are respectively arranged on one side and the other side of the handle rod 4. When the handle rod 4 is rotated clockwise, the first chain 5 will wind around the handle rod 4, while the second chain 6 will not wind, achieving the tightening of the first chain 5. Then, one side of the trowel plate 1 is lifted upward to adjust the angle of the trowel plate. At this time, by pulling the trowel plate 1 forward with the handle rod 4, the forward troweling state can be achieved. Conversely, when the handle rod 4 is rotated counterclockwise, the second chain 6 will wind around the handle rod 4, while the first chain 5 will not wind, achieving the tightening of the second chain 6. Then, the other side of the trowel plate 1 is lifted upward to adjust the angle of the trowel plate. At this time, by pushing the trowel plate 1 backward with the handle rod 4, the backward troweling state can be achieved.

[0038] Exemplarily, the trowel plate 1 is made of a high-strength and wear-resistant metal material (such as aluminum alloy or stainless steel), having sufficient rigidity and toughness to ensure that it is not easily deformed during troweling and can effectively transmit pressure. Its shape is designed as a rectangle, with a smooth bottom and ribs added on the top for reinforcement. The handle rod 4 is made of a lightweight but strong material, such as carbon fiber or alloy material, facilitating the operator to hold it for a long time without fatigue.

[0039] In a realizable manner, in combination with Figure 2 and Figure 3 As shown, the support assembly 2, as a key component connecting the trowel plate 1 and the handle mounting assembly 3, its design directly affects the stability and operability of the entire tool. The support assembly 2 mainly consists of two parts: a support base plate 200 and a support vertical plate 201. The support base plate 200 is fixedly connected to the middle position of the upper end face of the trowel plate 1. The support vertical plate 201 spans the width direction of the trowel plate 1 and is fixedly connected to the middle position of the support base plate 200. The support vertical plate 201 is hinged to the handle mounting assembly 3.

[0040] Specifically, the support base plate 200 is a sturdy flat plate, the material of which should match that of the troweling plate 1. It is usually made of high-strength and corrosion-resistant metal materials such as stainless steel or aluminum alloy. The support base plate 200 can be fixedly connected to the middle position of the upper end surface of the troweling plate 1 tightly and firmly through welding, bolt connection or other stable methods. In this way, the support base plate 200 not only provides a stable support foundation for the support vertical plate 201, but also ensures the stable connection between the entire support assembly 2 and the troweling plate 1, enabling the support assembly 2 to act on the concrete surface stably together with the troweling plate 1 during the troweling process. The support vertical plate 201 is a plate perpendicular to the support base plate 200, and its width is slightly less than or equal to the width of the troweling plate 1 so as to span and be fixedly connected to the middle position of the support base plate 200. The design of the support vertical plate 201 should consider the hinge requirement with the handle mounting assembly 3, so hinge holes are reserved on its side for connecting with the hinge shaft of the handle mounting assembly 3. The direction of the hinge axis should be parallel to the length direction of the troweling plate 1 to ensure that the handle mounting assembly 3 can rotate flexibly around this axis.

[0041] Through the ingenious design of the support base plate 200 and the support vertical plate 201 in this specific embodiment, the stable connection and flexible hinge between the support assembly 2 and the troweling plate 1 and the handle mounting assembly 3 are realized, providing a strong guarantee for the stability and operability of the entire concrete surface finishing and troweling tool.

[0042] Preferably, the support base plate 200 and the troweling plate 1 are connected by bolts 202. This connection method is not only simple and reliable, but also convenient for installation and maintenance, ensuring the stability and reliability of the entire concrete surface finishing and troweling tool during use. The material of the bolts 202 should be selected according to the specific working environment and usage requirements, and usually high-strength and corrosion-resistant stainless steel or alloy steel materials are selected. The diameter and length of the bolts should ensure that they can penetrate the support base plate 200 and the troweling plate 1 and provide sufficient thread length on both sides for installing nuts to achieve fastening.

[0043] In an implementable manner, in combination with Figure 3 and Figure 5 as shown, the handle mounting assembly 3, as a key part connecting the handle rod 4 and the support assembly 2, its design directly affects the operator's holding comfort and the overall stability of the tool. The handle mounting assembly 3 mainly consists of a handle mounting seat 300, connecting ear plates 301 and a hinge shaft 302. The handle mounting seat 300 is located directly above the support vertical plate 201, and the handle mounting seat 300 is rotatably connected to the handle rod 4. The connecting ear plates 301 are located on both sides of the support vertical plate 201 and are fixedly connected to the handle mounting seat 300. The hinge shaft 302 penetrates through the connecting ear plates 301 and the support vertical plate 201 along the length direction of the troweling plate 1 to hinge the support vertical plate 201 and the connecting ear plates 301.

[0044] Specifically, the handle mounting seat 300 is located directly above the support vertical plate 201 and maintains a certain distance therefrom, so as to provide sufficient installation space and rotational freedom for the handle bar 4. The handle mounting seat 300 is usually designed as a solid frame or box structure, and a rotation connection mechanism matching the handle bar 4 is provided inside or outside thereof, such as a bearing, a bushing or a pin hole. Through these mechanisms, the handle bar 4 can be stably mounted on the handle mounting seat 300 and can rotate freely within a certain range.

[0045] The connecting lugs 301 are located on both sides of the support vertical plate 201 and are symmetrically distributed to ensure balance. These lugs are fixedly connected to the bottom or side of the handle mounting base 300 by welding, bolting or other stable methods to form an integral structure. The design of the connecting lugs 301 should take into account the hinge requirements with the support vertical plate 201, so holes matching the hinge shaft 302 are reserved on them.

[0046] The hinge shaft 302 is a key component connecting the handle mounting assembly 3 and the support vertical plate 201. It passes through the reserved holes connecting the ear plate 301 and the support vertical plate 201 along the length direction of the wiping plate 1, thereby realizing the hinge connection between the two. The diameter and material of the hinge shaft 302 should be selected according to the actual load and working environment to ensure that it has sufficient strength and durability. Locking devices (such as locking nuts, retaining springs, etc.) are usually installed at both ends of the hinge shaft 302 to prevent the hinge shaft from loosening or falling off during use.

[0047] In this embodiment, the connecting ear plate 301 serves as a bridge between the handle mounting base 300 and the support vertical plate 201, and the two are hinged through the hinge shaft 302. This hinge method enables the handle mounting assembly 3 to rotate around the axis of the hinge shaft 302 at a certain angle, so as to meet the needs of different operating angles. At the same time, since the hinge point between the connecting ear plate 301 and the support vertical plate 201 is fixed, the handle mounting assembly 3 can remain relatively stable during the rotation process without excessive displacement or shaking. A stable connection and flexible hinge with the support vertical plate 201 are achieved, providing the operator with a more comfortable and stable gripping experience, and ensuring the stability and reliability of the entire concrete structure surface finishing and pressing tool during use.

[0048] Preferably, a bearing is installed on the handle mounting seat 300, and the axis of the bearing is orthogonally cross-shaped with the projection of the hinge axis on the horizontal plane. The handle rod 4 is fixedly connected to the inner ring of the bearing. This design enables the handle rod 4 to reduce friction and resistance during rotation, thereby providing a smoother and more comfortable operation experience. The selection of the bearing should be comprehensively considered based on factors such as the load, rotation speed, and working environment of the handle rod 4. In this embodiment, a rolling bearing is selected, and its inner and outer rings are respectively used to connect with the handle rod 4 and the handle mounting seat 300. Due to the presence of the bearing, the handle rod 4 can reduce the direct contact and friction with the handle mounting seat 300 during rotation, thereby reducing the operating resistance and improving the rotational flexibility.

[0049] In one implementable manner, as shown in combination with Figure 1 、 Figure 4 and Figure 5 , chain fixing pins 7 are respectively arranged at the positions corresponding to both sides of the trowel plate 1 on the handle rod 4. These fixing pins 7 are firmly installed on the handle rod 4 and are used to fix one end of the chain. One end of the first chain 5 and one end of the second chain 6 are respectively fixed to the corresponding chain fixing pins 7.

[0050] To fix the other end of the chain to the support base plate 200, chain fixing rings 8 are also respectively arranged at the positions corresponding to both sides of the trowel plate 1 on the support base plate 200. For example, the chain fixing rings 8 are fixed by welding or bolts. The other ends of the first chain 5 and the second chain 6 respectively pass through the corresponding chain fixing rings 8, and are fixed to the rings using connecting parts (such as chain buckles, locking pins, etc.).

[0051] In one implementable manner, as shown in combination with Figure 2 and Figure 4 , the handle rod 4 is a telescopic rod, that is, the handle rod 4 has a telescopic function. This design enables the tool to adapt to different ranges of operation requirements, improving the flexibility and convenience of use.

[0052] Specifically, the handle rod 4 adopts a telescopic rod structure, usually composed of multiple sections of sleeves. Each section of the sleeve is telescoped and fixed through a specific locking mechanism. This design allows the user to adjust the length of the handle rod 4 according to actual needs to adapt to different ranges of working surfaces. When it is necessary to trowel a concrete surface at a farther position, the handle rod 4 can be extended.

[0053] Exemplarily, the handle rod 4 is nested by multiple sections of sleeves with different diameters. Each section of the sleeve is internally designed with a metal spring piece or connected by threads. The user does not need to carry multiple handle rods with different lengths for replacement, and only needs to perform a simple telescopic operation to meet different operation requirements, greatly improving the work efficiency.

[0054] In one embodiment, the wiping plate 1 is made of a ribbed metal plate with a thickness of 5 mm, with dimensions of 2000 mm * 200 mm * 40 mm. The surface is required to be smooth and flat, and the metal plate has no warping or depression. The handle rod 4 is made of an aluminum alloy tube with a diameter of 40 mm.
