Description

Technical Field

[0001] The utility model relates to the technical field of plastering tools, in particular to a plastering device for building construction. Background Art

[0002] During the construction process, when laying wall tiles or facing tiles, mortar is usually applied directly to the back of the tiles with a trowel. The thickness of the plastering is difficult to be consistent each time, and the uniformity cannot be guaranteed, resulting in partial rework when laying tiles and not being able to complete the task in one go, which requires a high level of technical skill from the plasterer.

[0003] According to a publicly disclosed construction plastering device (announcement number: CN214220503U), the above application includes a box body and a plastering plate arranged above the box body, the longitudinal section of the box body is a nearly right-angled trapezoidal structure, the front end of its horizontal bottom edge is provided with a first serration, and a groove for placing the plastering plate is provided above the top plate; a rotating flap is provided on the side of the top plate close to the first serration, and a third serration is provided on the outer side of the flap, and the locking column on the outer side of the side wall of the box body is connected to the arc-shaped sliding groove for adjusting the angle at both ends of the flap.

[0004] However, in actual use, the above-mentioned plastering device needs to use gravity to make the mortar flow to the left side of the box body and then be applied to the wall. When plastering under the ceiling or beam, the direction of gravity is opposite to the flow direction of the mortar. The mortar cannot flow naturally to the top, and the device cannot feed normally, affecting the construction effect. In view of this, we propose a plastering device for building construction. Utility Model Content

[0005] The purpose of the utility model is to provide a plastering device for building construction to solve the problems raised in the above background technology.

[0012] Preferably, one end of the spring abuts against the inner wall of the shell, and one end of the spring away from the inner wall of the shell abuts against the push plate, and the spring pushes the push plate to move toward the notch through elastic deformation.

[0013] Preferably, the outer wall of the push plate abuts against the inner wall of the shell, and the rubber strip is movably connected to the inner wall of the sleeve.

[0017] 2.

When the lateral position of the roller changes, the position where it contacts the wall also changes, thereby changing the distance between the groove and the wall, realizing the control of the mortar thickness, adapting to different construction requirements, and ensuring that the mortar layer thickness matches the actual construction requirements.

[0027] like Figure 1-Figure 8 As shown, the utility model provides a technical solution: a construction plastering device, including a shell 1, a plastering assembly 2 is arranged on the top of the shell 1, and the plastering assembly 2 includes a limiting bolt 201, a mounting plate 202, a frame 203, a mounting column 204, a roller 205, a sleeve 206, a movable rod 207, a rubber strip 208, a push plate 209, a spring 210, a connecting rod 211, a slot 212, and a limiting plate 213.

[0028] In one embodiment of the utility model, the cross-section of the shell 1 is a right-angled trapezoid, the upper base of the right-angled trapezoid is located on the side away from the mounting plate 202, the inclined surface of the right-angled trapezoid is provided with a slot 4, the inclined surface of the right-angled trapezoid is hinged with a cover plate 5, the top end surface of the mounting plate 202 is fixedly connected with a handle 3, the mounting plate 202 is hinged to the shell 1, the mounting plate 202 is threadedly connected to the limit bolt 201, the limit bolt 201 is socketed with the shell 1, the top end surface of the mounting plate 202 is fixedly connected with a frame 203, the side wall of the frame 203 is provided with a mounting column 204, the end surface of the mounting column 204 is rotatably connected with a roller 205, the number of rollers 205 is provided in a plurality of groups, and a plurality of groups of rollers 205 are equidistantly arranged on the side of the frame 203, the rollers 205 are in contact with the wall, so that the device is perpendicular to the wall.

[0029] The sleeve 206 is fixedly connected to the inner wall of the shell 1, and the sleeve 206 is sleeved with the movable rod 207. The side wall of the movable rod 207 is fixedly connected with a rubber strip 208. The end of the movable rod 207 away from the sleeve 206 is fixedly connected with a push plate 209. The side wall of the sleeve 206 is sleeved with a spring 210. One end of the spring 210 abuts against the inner wall of the shell 1. The end of the spring 210 away from the inner wall of the shell 1 abuts against the push plate 209. The spring 210 is elastically The deformation pushes the push plate 209 to move toward the slot 4, and the outer wall of the push plate 209 abuts against the inner wall of the shell 1. The rubber strip 208 is movably connected to the inner wall of the sleeve 206. The rubber strip 208 increases the friction between the sleeve 206 and the movable rod 207, thereby slowing down the movement speed of the push plate 209. The connecting rod 211 is fixedly connected to the side wall of the push plate 209. The side wall of the connecting rod 211 is provided with a slot 212. The side wall of the shell 1 is rotatably connected to the limiting plate 213.

[0030] Rotate the mounting plate 202, and then rotate the limit bolt 201 to fix the position of the mounting plate 202. When the mounting plate 202 is in a horizontal state, the shell 1 is slightly tilted to the lower left so that the mortar can flow out through the slot 4. The roller 205 is placed against the wall, and then the device is pushed. The roller 205 rolls on the wall, thereby driving the shell 1 to move on the wall. The mortar flows out of the slot 4 and is then smoothed by the outer wall of the shell 1. Through the support of the roller 205, the device and the wall are kept vertical, ensuring that the distance between the slot 4 and the wall is constant. This constant distance makes the thickness of the mortar flowing out consistent, thereby achieving a uniform plastering effect, avoiding the problem of uneven thickness of the mortar layer, and improving the construction quality.

[0031] When it is necessary to plaster the ceiling, the limit plate 213 is rotated to cancel the clamping connection between the limit plate 213 and the connecting rod 211. Under the elastic deformation of the spring 210, the push plate 209 is pushed to move toward the slot 4, and then the mortar is pushed toward the slot 4 to achieve plastering of the ceiling, overcoming the problem of insufficient gravity. It is particularly suitable for construction scenarios in the anti-gravity direction such as ceiling plastering. The rubber strip 208 increases the friction between the sleeve 206 and the movable rod 207, thereby slowing down the movement speed of the push plate 209, avoiding excessive mortar outflow at one time, preventing uneven plastering thickness due to mortar accumulation during construction, and improving construction quality.

[0032] In addition, the top end face of the mounting plate 202 is fixedly connected to the frame body 206, and the side wall of the frame body 206 is threadedly connected to the adjusting screw 7, the adjusting screw 7 is socketed with the mounting column 204, and the mounting column 204 is socketed with the frame body 1 203. The adjusting screw 7 is rotated to make the adjusting screw 7 move laterally, thereby adjusting the lateral position of the mounting column 204 and the roller 205. When the lateral position of the roller 205 changes, the position where it contacts the wall also changes, thereby changing the distance between the slot 4 and the wall, thereby realizing the control of the mortar thickness, adapting to different construction requirements, and ensuring that the mortar layer thickness matches the actual construction requirements.

[0033] The mortar is then smoothed by the outer wall of the shell 1. The roller 205 is pressed against the wall to push the device. The roller 205 rolls on the wall, thereby driving the shell 1 to move on the wall. The mortar flows out of the groove 4 and is then smoothed by the outer wall of the shell 1. The device is supported by the roller 205 and is kept vertical to the wall to ensure that the distance between the groove 4 and the wall is constant. This constant distance makes the thickness of the mortar flowing out consistent, thereby achieving a uniform plastering effect and avoiding the problem of uneven thickness of the mortar layer. When the ceiling needs to be plastered, the push plate 209 is pushed to move toward the groove 4 under the elastic deformation of the spring 210, and then the mortar is pushed toward the groove 4 to achieve plastering of the ceiling. This overcomes the problem of insufficient gravity and is particularly suitable for construction scenes in the anti-gravity direction such as ceiling plastering.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
