Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wall plastering technology, and in particular relates to a wall plastering thickness control device. Background Technology
[0002] During building construction, such as the construction of shear walls, after the main structure of the wall is completed, the wall surface needs to be plastered, such as by applying cement to the wall surface, so that it is easier to apply paint on the smooth plaster layer later.
[0003] During construction, it is necessary to control the thickness of the plaster layer. Controlling the thickness of the plaster layer facilitates subsequent construction (too thin a layer will not guarantee the flatness of the wall surface, while too thick a layer will result in excessive use of concrete plaster). Therefore, the thickness of the plaster layer is often adjusted according to the flatness of the wall surface. If the flatness is low, the plaster thickness needs to be increased to ensure the flatness of the wall surface after plastering.
[0004] In current construction practices, workers apply cement mortar to the wall from the bottom (keeping a certain distance from the ground) using a squeegee. However, due to the inability to control the amount of cement mortar applied, it is difficult to control the thickness of the plaster during actual work (i.e., some parts of the wall are too thick, while others are too thin). Therefore, more experienced workers are often needed to perform the plastering work.
[0005] During the plastering process, the squeegee needs to constantly spread the applied plaster, resulting in a large amount of plaster falling onto the ground. Once the plaster falls to the ground and picks up dust and other impurities, its adhesion decreases, making it unusable for re-application to the wall, leading to significant plaster waste. Furthermore, the plaster residue left on the ground after plastering makes subsequent cleaning difficult. Utility Model Content
[0006] Based on the above background, the purpose of this utility model is to provide a wall plaster thickness control device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A wall plaster thickness control device includes a bottom rail, on the top of which a horizontally movable plaster track is slidably mounted.

[0045] Example 1
[0046] like Figure 1-8 As shown, a wall plastering thickness control device includes a bottom rail 1, on the top of which a horizontally movable plastering track is slidably mounted. The plastering thickness is adjusted by using the plastering track as a reference (the plastering force is adjusted by adjusting the scraper during the plastering process).
[0047] Specifically, the plastering track includes a vertical track section 4, which is integrally formed with a horizontal track section (i.e., the plastering track is L-shaped). By adjusting the plastering track, the distance between the vertical track section 4 and the wall surface can be adjusted. During the plastering process, the operator uses the distance (gap) between the vertical track section 4 and the wall surface as a reference. After the plaster is applied to the wall, it is spread and leveled using a squeegee. After plastering, the bottom of the plaster should be kept against the inner wall of the vertical track section 4.
[0048] The sliding mechanism of the plastering track is as follows: several sliding blocks 41 are fixedly connected to the bottom of the horizontal track section, and a sliding groove 11 is provided on the bottom track 1 to limit the sliding of the sliding blocks 41. The longitudinal cross-sectional shape of the sliding block 41 is T-shaped; the longitudinal cross-sectional shape of the sliding groove 11 is T-shaped.
[0049] During construction, the workers apply plaster vertically to the wall along the plastering track. After completion, they move the plastering track to the next location and repeat the process.
[0050] Specifically, a long sliding opening 12 is provided on the rear side wall of the plastering track, which connects to the sliding groove 11. A screw 42 that passes through the long sliding opening 12 is fixedly connected to the rear side wall of the slide block 41, and a positioning nut 421 is threaded onto the screw 42.
[0051] During the horizontal sliding process, the positioning nut 421 is loosened. At this time, during the horizontal sliding of the plastering track, the screw slides in the long sliding opening. After the sliding adjustment, the positioning nut 421 is tightened.
[0052] Example 2
[0053] like Figure 1-8 As shown, in this embodiment, based on the structure of embodiment 1, during the plastering process, the bottom rail 1 is installed at the lower end of the shear wall. Specifically, the bottom of the bottom rail 1 is installed on the pull tab through hole on the shear wall through two installation structures set at intervals on the left and right (during the pouring process of the shear wall, the template is tightened by the tensioning screw, so the pull tab through hole is formed when the wall is poured, and it is a through hole structure); the distance between the plastering rail and the wall surface is adjusted by the installation structure to adjust the plastering thickness.
[0054] Specifically, the installation structure includes a vertical adjustment screw 21 rotatably connected to the bottom of the bottom rail 1 (the specific rotatable connection method is: a boss 211 rotatably connected to the vertical adjustment screw 21 is fixedly connected to the bottom of the bottom rail 1, and a rotating protrusion 2111 with a limit rotation in the boss 211 is fixedly connected to the top of the vertical adjustment screw 21. Correspondingly, a groove for limiting the rotation of the rotating protrusion 2111 is opened at the bottom of the boss 211). A horizontal screw 22 is threadedly connected to the vertical adjustment screw 21, and the horizontal screw 22 is installed on the pull tab through hole.
[0055] Specifically, the outer end of the horizontal screw 22 is fixedly connected to a nut head 221 that is threaded onto the vertical adjusting screw 21; a pull plate 223 is slidably connected to the horizontal screw 22; and two nuts 222, respectively located on both sides of the pull plate, are threaded onto the inner side of the horizontal screw 22.
[0056] During the operation, first, the horizontal screw 22 is passed through the pre-reserved pull tab through hole on the wall. Then, the pull tab on the rear side is pushed to abut the pull tab 223 through hole. The other end of the horizontal screw 22 also has a nut 222. Adjust the nuts 222 on both sides to abut to keep the horizontal screw 22 in position and installed.
[0057] During installation, the distance between the plaster track and the wall can be adjusted by changing the depth through which the horizontal screw 22 passes through the wall.
[0058] In actual operation, a pair of pull tabs 223 can be threaded onto the horizontal screw 22. After the horizontal screw 22 is passed through, the pull tab on the other side is inserted and the nut is tightened.
[0059] This method allows for adjustable spacing between the plastering track and the wall. It cleverly utilizes pre-drilled holes in the shear wall as an auxiliary structure, facilitating the installation of the entire device at the lower end of the shear wall.
[0060] After the horizontal screw 22 is installed, the operator can simultaneously rotate the vertical adjusting screws 21 on both sides (the upper end of the vertical adjusting screw 21 is rotatably connected to the boss 221, and the lower end is threadedly connected to the nut head 221, so the height can be adjusted by the thread after rotation) to adjust the height of the plastering track.
[0061] This method allows for adjustment of the plastering track height based on the height of the lower edge of the wall and the pre-reserved blank area (non-painted area) on the ground during the plastering process.
[0062] Example 3
[0063] like Figure 1-8 As shown, in this embodiment, based on the structure of embodiment 1, a pullable mortar pull seat 3 is installed on the top of the above-mentioned plastering track (the upper handle 31 is fixed at the center of the rear side wall of the mortar pull seat 3 for easy pulling). Excess mortar on the wall is scraped off by the scraper and falls into the mortar pull seat 3.
[0064] Specifically, the two sides of the ash material pull-out seat 3 are respectively mounted on the inner sidewall of the vertical track section 4 via spring structures 32. The spring structure 32 includes a first rod 321 slidably connected to the ash material pull-out seat 3, and a spring 322 sleeved on the outer side of the first rod 321; the inner end of the spring 322 is fixed to the sidewall of the ash material pull-out seat 3, and a spring fixing seat is fixedly connected to the outer end of the first rod 321, and the outer end of the spring 322 is fixed to the spring fixing seat.
[0065] Meanwhile, the inner end of the first rod 321 is hinged to the second rod 323 through the hinge structure A; the second rod 323 is slidably connected to the ash material pull-out seat 3, and the inner end of the second rod 323 is fixedly connected to the vertical track part 4.
[0066] The specific hinge method is as follows:
[0067] The hinge structure A includes a hinge interface formed on the first rod 321, and a hinge tongue fixedly connected to the second rod 323, which is hinged in the hinge interface. The hinge tongue is hinged in the hinge interface by a pin.
[0068] Correspondingly, a sliding cavity is provided on both sides of the ash material pull-out seat 3, and the first rod 321 and the second rod 323 are limited to slide within the sliding cavity.
[0069] Under normal circumstances, the hinge structure is located in the sliding cavity. During the plastering process, a large amount of cement ash falls into the ash material pull seat 3. At this time, the operator pulls the ash material pull seat 3 until the bottom of the ash material pull seat 3 is misaligned with the plastering track. At this time, the spring 322 is compressed during the pulling process, and the hinge structure gradually moves from inside the sliding cavity to outside the cavity. At this time, the operator flips the ash material pull seat 3, and the ash material pull seat 3 tilts downward to facilitate the sliding of cement ash.
[0070] After cleaning, the operator flips the ash material pull-out seat 3 to a horizontal position again. Under the elastic restoring force of the spring 322, the ash material pull-out seat 3 moves inward to reset (at this time, the hinge structure returns to the sliding cavity again).
[0071] The above structure facilitates the collection of fallen cement dust during the plastering process, thus solving the technical defects of traditional plastering, which results in a large amount of unusable cement dust, material waste, and difficulty in cleaning the ground.
[0072] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
