Description

[0002] During concrete building construction, the pouring formwork of shear wall and floor is set up first, and the reinforced mesh is bound well, then the shear wall below the floor is poured first, and then the floor is poured. However, during pouring the shear wall, the pouring opening of the wall formwork is narrow, and the wall concrete slurry is easy to fall on the floor formwork. If the fallen wall concrete slurry is not cleaned in time, it will be finally solidified to form ash on the floor formwork, resulting in a joint stub during pouring the floor later, and the joint stub crack is obvious, and there is a concrete leakage phenomenon, which affects the structure quality of the whole concrete floor. In addition, due to the different concrete strength types of the shear wall and the floor, after the floor is poured and the formwork is removed, the ash on the floor bottom surface will form a honeycomb rough surface. The honeycomb rough surface caused by the dry ash and the joint stub of the repaired concrete cast-in-place floor bottom surface in the later period not only wastes a lot of labor and funds, but also the quality of the repaired surface is uneven, which may cause more serious damage to the structure quality.

[0003] However, due to the small distance between the bottom layer of the floor reinforced mesh and the floor formwork, the large particles in the fallen wall concrete cannot be removed from the reinforced mesh (removed to the inside of the wall formwork), and the wall concrete slurry contains a lot of solid matters. The area of the reinforced mesh is large, and it is full of multiple rows and columns of grids. It is extremely low in efficiency and time-consuming to pick out the solid matters in each grid one by one, which seriously affects the construction efficiency. CONTENT OF THE UTILITY MODEL

[0022] The technical solutions of the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0023] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the internal parts of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0024] Reference Attachment Figure 1-4 This embodiment provides a device for cleaning concrete under a steel mesh, which includes a bottom support plate 10, a pusher plate 20 and a mesh lifting assembly 30. The bottom support plate 10 and the mesh lifting assembly 30 are fixedly connected, the pusher plate 20 is movably arranged between the bottom support plate 10 and the mesh lifting assembly 30, the mesh lifting assembly 30 is used to lift the steel mesh, and the pusher plate 20 is used to scrape the concrete under the steel mesh.

[0025] There is a small distance between the floor formwork and the steel mesh at the bottom layer of the floor slab, which is not enough to allow large particles of solid in the spilled wall concrete slurry to pass through. The mesh lifting component 30 is used to first lift the steel mesh in a small range, which does not affect the structure and position of the steel mesh, but can increase the distance between the floor formwork and the steel mesh. At this time, the slurry pushing plate 20 is pushed and the wall concrete slurry is pushed into the wall formwork by using the slurry pushing plate 20, quickly completing the cleaning work on the upper surface of the floor formwork, preventing the spilled wall concrete slurry from finally setting on the floor formwork to form ash slag, thereby affecting the pouring quality and surface flatness of the floor slab. The device has a simple structure, is easy to operate, and has high cleaning efficiency.

[0026] Reference Attachment Figure 2The lifting net assembly 30 comprises a first horizontal plate 31, a second horizontal plate 32 and an inclined pressing plate 33. The first horizontal plate 31 is provided with a horizontal rotating shaft 34. The second horizontal plate 32 and the inclined pressing plate 33 extend from the horizontal rotating shaft 34 in opposite directions, respectively. The second horizontal plate 32 is rotationally connected to the horizontal rotating shaft 34. The inclined pressing plate 33 is fixedly connected to the second horizontal plate 32 and forms an acute angle with the first horizontal plate 31. When the inclined pressing plate 33 is pressed down, the inclined pressing plate 33 exerts a force on the second horizontal plate 32. The second horizontal plate 32 can rotate about the horizontal rotating shaft 34. The end portion of the second horizontal plate 32 away from the horizontal rotating shaft 34 can be lifted up, thereby achieving the function of lifting the reinforcement net.

[0027] Specifically, the first horizontal plate 31 is provided with two sets of first mounting plates 35 opposite to each other. The second horizontal plate 32 is located between the two sets of first mounting plates 35. The facing surfaces of the two sets of first mounting plates 35 are respectively fixedly provided with the horizontal rotating shaft 34.

[0028] The inclined pressing plate 33 can be fixedly welded to the second horizontal plate 32 or detachably connected to the second horizontal plate 32. When the detachable connection mode is adopted, the inclined pressing plate 33 can be detached when the device is not in use, so that it is not in the state of being obliquely lifted up, thereby saving storage space and preventing accidental damage.

[0029] In implementation, two sets of second mounting plates 36 opposite to each other can be provided on the second horizontal plate 32. The inclined pressing plate 33 is located between the two sets of second mounting plates 36. The second mounting plate 36 and the inclined pressing plate 33 are respectively provided with a corresponding special-shaped positioning pin hole 37. The special-shaped positioning pin hole 37 is provided with a special-shaped positioning pin 38. The special-shaped positioning pin 38 is used to facilitate the positioning of the angle of the inclined pressing plate 33, so that it can be installed in the form of forming an acute angle with the first horizontal plate 31 when needed.

[0030] The shape of the special-shaped positioning pin hole 37 can be configured according to specific use requirements. For example, in the embodiment, the cross section of the special-shaped positioning pin hole 37 is a regular polygon, more specifically, a regular hexagon. The outer contour of the special-shaped positioning pin 38 is a regular hexagonal prism. At least one special-shaped positioning pin hole 37 on the inclined pressing plate 33 is in a direction that is completely coincident with the special-shaped positioning pin hole 37 on the second mounting plate 36 when the inclined pressing plate 33 is in the state of use, i.e., when it forms a specified angle with the first horizontal plate 31.

[0031] Since the plate shape of the inclined pressing plate 33 can be selected according to the use requirement, one special-shaped positioning pin hole 37 can only meet the assembly state of the device in use, and when it needs to be stored, if the special-shaped positioning pin 38 is removed and stored separately, it is easy to be lost, and the inclined pressing plate 33 can be stacked on the second horizontal plate 32, but can move freely, and is also easy to be lost or damaged. Therefore, at least two groups of special-shaped positioning pin holes 37 with different directions can be arranged on each side of the inclined pressing plate 33, one group of which meets the condition that the special-shaped positioning pin hole 37 is completely overlapped with the special-shaped positioning pin hole 37 on the second mounting plate 36 when the inclined pressing plate 33 is in the use state, that is, it forms a specified angle with the first horizontal plate 31, and the other group meets the condition that the special-shaped positioning pin hole 37 is completely overlapped with the special-shaped positioning pin hole 37 on the second mounting plate 36 when the inclined pressing plate 33 is in the storage state, that is, it is stacked with the second horizontal plate 32. In this way, when the inclined pressing plate 33 is stored, the special-shaped positioning pin 38 can also be inserted into the special-shaped positioning pin hole 37, so that each structure in the device is connected as a whole, preventing the loss of parts.

[0032] In the embodiment, a limiting block 40 is arranged between the bottom supporting plate 10 and the net lifting assembly 30, and an elongated through hole 21 is arranged on the pushing plate 20, the limiting block 40 is arranged in the elongated through hole 21, the width of the elongated through hole 21 is greater than the cross-sectional dimension of the limiting block 40, and the length of the elongated through hole 21 is also greater than the cross-sectional dimension of the limiting block 40. Therefore, the pushing plate 20 can slide along the length direction of the elongated through hole 21 and also can rotate around the limiting block 40. In use, the direction of moving the pushing plate 20 can be selected according to the specific requirement, and the wall concrete slurry spilled on the floor formwork can be pushed and scraped away by using the appropriate side of the pushing plate 20.

[0033] In order to facilitate operation, a push-pull handle 22 is arranged on the long end of the pushing plate 20, so as to facilitate the workers to move the pushing plate 20 in different directions.

[0034] The method for cleaning the wall concrete slurry between the reinforcing mesh and the floor formwork by using the above device includes the following steps:

[0035] The device is inserted into the gap between the reinforcing mesh and the floor formwork, the inclined pressing plate 33 is pressed down, the second horizontal plate 32 is lifted away from the end of the horizontal rotating shaft 34, and the reinforcing mesh is lifted up.

[0036] The pushing plate 20 is slid along the length direction of the elongated through hole 21 or rotated around the limiting block 40, and the wall concrete slurry on the floor formwork is scraped into the inside of the shear wall formwork.

[0037] Compared with the prior art, the beneficial effect of the present invention is that: the mesh lifting assembly 30 is used to first lift the steel mesh in a small range to increase the distance between the floor formwork and the steel mesh, and then the slurry pushing plate 20 is pushed and the wall concrete slurry is pushed into the wall formwork by using the slurry pushing plate 20, which can quickly complete the cleaning work on the upper surface of the floor formwork, and prevent the spilled wall concrete slurry from finally setting on the floor formwork to form ash residue, thereby affecting the pouring quality and surface flatness of the floor. The structure of the device is simple, the operation is convenient, and the cleaning efficiency is high.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
