Description

Technical Field

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

[0002] When constructing the walls inside a building, in order to improve the flatness of the walls, some customers will require that gray reinforcement be set at intervals on the walls before plastering the walls, so as to limit the flatness of the walls and the thickness of the plastering, thereby making the walls after construction smoother and improving the quality of the wall construction. The above construction process is called reinforcement. The existing reinforcement construction is generally achieved with the help of a reinforcement ruler. Materials such as gypsum are applied to the ruler in advance, and then the ruler is attached to a designated position on the wall. After the gypsum is initially solidified, the ruler is separated from the gypsum. The separation process is generally performed manually by scraping. The scraped gypsum forms gray reinforcement on the wall, which is used as a basis to ensure the thickness of the subsequent plastering. However, when the gypsum and the ruler are manually separated, it is easy to cause the cross-section of the upper and lower scraped positions of the gypsum to be uneven, thereby making the end faces of the formed gray reinforcement uneven, affecting the flatness of the subsequent plastering and reducing the quality of the reinforcement construction. Utility Model Content

[0003] The utility model aims to provide a plastering reinforcement punching device, which can solve the technical problem that the uneven end surface of the mortar reinforcement affects the quality of the mortar reinforcement when it is separated from the ruler, and accurately scrapes the gypsum and the ruler after initial setting to make the end surface smoother, thereby ensuring the quality of the mortar reinforcement after molding and the smoothness of the wall plastering construction.

[0022] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0023] See attached Figure 1 and 2The utility model is a plastering rib punching device, the main structure of which includes a handle 1, which is a long rod-shaped structure, which is convenient for an operator to hold the handle 1 for operation, and a U-shaped frame 2 is welded or bolted to the end of the handle 1, and the top of the U-shaped frame 2 is open. Preferably, the U-shaped frame 2 and the handle 1 are made of metal to ensure structural strength and service life. A scraping line 3 is provided on the top of the U-shaped frame 2, and the scraping line 3 is preferably a metal wire or a fishing line to ensure that the size of its cross-section is small enough and has a large structural strength, is not easy to break and maintains To ensure the flatness of the cut surface, during operation, the operator holds the handle 1 and sets the U-shaped frame 2 on the top of the rib ruler, so that the scraping line 3 is close to the edge of the ruler that contacts the gypsum, and then moves the handle 1 downward to make the scraping line 3 scrape the initially set gypsum along the edge of the ruler, so that the end surface of the remaining gypsum gray reinforcement is smoother, ensuring the quality of gray reinforcement construction and the flatness of subsequent plastering construction. The two sides of the top of the U-shaped frame 2 are respectively provided with a fixing cap 4 and a winding shaft 5, and the fixing cap 4 is movably connected to the U-shaped frame 2, so that the fixing cap 4 can be easily removed during later maintenance. The wire scraper 3 is preferably a wire scraper 3 having a plurality of scissor legs, a plurality of scissor legs and a plurality of scissor legs having a plurality of scissor legs. The wire scraper 3 is preferably a wire scraper 3 having a plurality of scissor legs, a plurality of scissor legs and a plurality of scissor legs having a plurality of scissor legs. The wire scraper 3 is preferably a wire scraper 3 having a plurality of scissor legs, a plurality of scissor legs and a plurality of scissor legs having a plurality of scissor legs. The parts restrict the rotation of the winding shaft 5 to ensure the effect of the scraping wire 3 scraping and breaking operation. When the scraping wire 3 is broken, the fixing cap 4 can be removed, and then the restriction of the positioning component can be released to loosen the scraping wire 3 from the winding shaft 5, and the broken position can be re-fixed on the fixing cap 4. Thereafter, the fixing cap 4 can be installed on the U-shaped frame 2 and the winding shaft 5 can be rotated to tighten the scraping wire 3. The positioning component is reused to restrict the rotation of the winding shaft 5, thereby realizing the rapid re-fixation of the scraping wire 3 after breakage, extending the service life of the device, and making the later inspection and maintenance of the device more convenient and efficient.

[0024] Preferably, see Attachment Figure 3 and 6 The positioning assembly includes a ratchet 6 and a pawl 7. The ratchet 6 is welded or integrally formed and fixed on the winding shaft 5. The pawl 7 is rotatably connected to the U-shaped frame 2 through a pin shaft. A torsion spring is provided between the pawl 7 and the U-shaped frame 2. The pawl 7 is meshed and connected with the ratchet 6. Such a structure enables the winding shaft 5 to rotate only in the direction of tightening the scraping wire 3 without causing the scraping wire 3 to relax. The structure is simple, and effective restriction and adjustment of the state of the scraping wire 3 are achieved, ensuring the effect of the scraping wire 3 on scraping and separating the plaster from the ruler.

[0025] Preferably, a protective shell 8 is welded or bolted to the outside of the winding shaft 5, and the ratchet 6 and pawl 7 are both located inside the protective shell 8. An inspection port 9 is provided at the bottom of the protective shell 8. Such a structure utilizes the protective shell 8 to protect the ratchet 6 and pawl 7 on the internal winding shaft 5, thereby ensuring that the meshing structure of the two is not easily contaminated by external materials such as gypsum, thereby ensuring the limiting effect of the positioning component on the rotation of the winding shaft 5.

One end of the scraper wire 3 passes through the interior of the tube seat 10 and is wound around the winding shaft 5. Such a structure can easily unscrew the fixing cap 4 from the tube seat 10 during maintenance after the scraper wire 3 is broken, and the fixing cap 4 can be screwed on again after the end face is re-fixed to the fixing cap 4, thereby further simplifying the replacement and maintenance steps of the scraper wire 3 and improving the efficiency and convenience of maintenance.

[0027] Preferably, see Attachment Figure 4 and 5 The fixing cap 4 is provided with a through hole 11, and a fixing column 12 is welded or integrally formed in the through hole 11, and the end of the scraper wire 3 is tied to the fixing column 12. Such a structure makes the fixing cooperation between the scraper wire 3 and the fixing cap 4 more convenient and firm. When replacing it later, it is only necessary to tie the broken position of the scraper wire 3 to the fixing column 12 in the through hole 11 again, and the maintenance operation is simpler and more convenient.

[0028] Preferably, a cleaning roller 13 is provided on the sliding sleeve of the scraping line 3. Specifically, a scraping hole is provided at the center position of the cleaning roller 13, and the scraping hole sleeve is provided on the outside of the scraping line 3. When a large amount of plaster and other materials remain on the scraping line 3 due to repeated use, the residual plaster can be scraped off by sliding the cleaning roller 13 to prevent the plaster from solidifying on the scraping line 3 and affecting the subsequent scraping effect.

[0029] Working principle: The structure of the utility model comprises a U-shaped frame 2 arranged on a handle 1, and a scraping wire 3 is arranged on the top of the U-shaped frame 2. When separating the ruler from the initially set gypsum, such a structure only needs to hold the handle 1 to put the U-shaped frame 2 on the top of the ruler from the top, so that the scraping wire 3 fits the edge of the ruler, and then move the handle 1 downward to make the scraping wire 3 perform a separation operation along the edge of the ruler, so that the end surface of the gray reinforcement remaining after separation is smoother, the quality of the gray reinforcement after molding is guaranteed, and the flatness of the subsequent plastering is guaranteed; movable fixing caps 4 and rotating winding shafts 5 are respectively arranged on both sides of the U-shaped frame 2, and the scraping wire 3 One end of the scraper wire 3 is fixedly connected to the fixing cap 4, and the other end passes through the top of the U-shaped frame 2 and is wound around the winding shaft 5, and a positioning assembly used in conjunction with the winding shaft 5 is provided on the U-shaped frame 2. Such a structure makes the installation of the scraper wire 3 more convenient, and at the same time, the restriction of the positioning assembly can be released after the scraper wire 3 is worn and broken.
