Technical Field
[0001] The utility model relates to the technical field of concrete formwork, in particular to a cutting device for decorative fair-faced concrete formwork. Background Technique
[0002] Fair-faced concrete is a manifestation of architectural modernism. Because of its extremely decorative effect, it is also called decorative concrete. The basic idea is that after the concrete is poured, there is no need for any painting, tiling, stone pasting and other materials, showing a simple method of concrete. For fair-faced concrete, formwork is usually required. Fair-faced concrete formwork pays more attention to formwork selection, formwork segmentation, panel segmentation, arrangement of tie bolts and formwork surface flatness. Therefore, during the construction process, the formwork needs to be cut. Most of the existing cutting devices use hand saws or table saws to cut the formwork. In order to ensure the accuracy of formwork splicing and the flatness of the formwork surface, it is usually necessary to deburr the cutting area. The existing cutting and deburring usually require two processes, and the formwork needs to be transported before deburring the burrs after cutting. The formwork with burrs is easy to cause harm to the staff, reducing the construction safety. Content of the Utility Model
[0003] Aiming at the above problems, the purpose of the utility model is to provide a cutting device for decorative fair-faced concrete formwork, which solves the problem that the existing cutting and deburring usually require two processes, and the formwork needs to be transported before deburring the burrs after cutting. The formwork with burrs is easy to cause harm to the staff, reducing the construction safety.
[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is: a cutting device for decorative fair-faced concrete formwork, including a workbench and an installation cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.
[0034] Such as Figure 1-5As shown in the figure, a decorative fair-faced concrete formwork cutting device includes a workbench 1 and a mounting cover 4. A collection trough 11 is installed below the workbench 1, and guide rods 2 are installed above the workbench 1. A slider 21 is penetrated and installed on the guide rods 2. A mounting bracket 22 is welded and installed at the top of the slider 21, and a cutting saw 23 is installed in the middle of the mounting bracket 22. A driving motor 24 is installed on the mounting bracket 22, and a grinding head 25 is connected below the driving motor 24. A spring 3 is installed below the mounting bracket 22, and a guide rod 31 is connected below the spring 3. A guide roller 32 is installed below the guide rod 31. The mounting cover 4 is installed on both sides of the workbench 1, and an exhaust fan 41 is installed on the outside of the mounting cover 4. A filter plate 42 is installed inside the mounting cover 4, and a protective net 43 is snap-fitted inside the mounting cover 4. Pull the mounting bracket 22 to drive the cutting saw 23 to move towards the formwork for cutting. After cutting, the driving motor 24 drives the grinding head 25 to rotate to grind the cutting seam of the formwork. By using this method, it is possible to avoid the harm caused by burrs to the staff when the staff carry the formwork. During the cutting process, the exhaust fan 41 pumps the nearby air. The dust generated during the cutting process enters the inside of the mounting cover 4 through the protective net 43, and then the air is discharged after being filtered by the filter plate 42, and the dust stays inside the mounting cover 4. By using this method, it is possible to effectively reduce the escape of dust during the cutting process and ensure the environment at the cutting site. The number of the guide rods 2 is two, and the guide rods 2 and the workbench 1 are arranged in parallel with each other. The two guide rods 2 can make the mounting bracket 22 slide smoothly and reliably along the guide rods 2, and the parallel arrangement can make the mounting bracket 22 more stable when sliding along the guide rods 2. A chute is opened below the slider 21, and through the chute, the slider 21 can slide more reliably and smoothly along the guide rods 2. The guide rod 31 and the mounting bracket 22 form a sleeved installation structure, and two guide rods 31 are symmetrically arranged about the center line of the mounting bracket 22. Through the sleeve between the guide rod 31 and the mounting bracket 22, the guide rod 31 can be retracted into the inside of the mounting bracket 22, thereby facilitating the lifting of the guide roller 32. The two guide rods 31 can facilitate the smooth and rapid movement of the mounting bracket 22. The mounting cover 4 and the workbench 1 are fixed by bolts. By using bolts, the installation of the mounting cover 4 and the workbench 1 can be more convenient and rapid. The exhaust fans 41 are equally spaced inside the mounting cover 4. The equally spaced exhaust fans 41 can facilitate the dust generated during the cutting of the device to be sucked into the inside of the mounting cover 4. The filter plate 42 is inclined. The inclined filter plate 42 can filter the dust, thereby facilitating the dust to be filtered to the bottom of the mounting cover 4. A discharge hole is provided below the mounting cover 4. Through the discharge hole, the dust inside the mounting cover 4 can be discharged, thereby facilitating the collection of the dust.
[0035] The working principle of the utility model is as follows: when using the device, place the template to be cut above the workbench 1, lift the guiding roller 32 upward, the user turns on the cutting saw 23 and the driving motor 24, the user pulls the mounting bracket 22 to drive the cutting saw 23 to move towards the template. During the movement, the slider 21 cooperates with the guide rod 2 to guide the mounting bracket 22, and the guiding roller 32 enables the mounting bracket 22 to move smoothly, thereby cutting the template. After the template is cut, the driving motor 24 drives the grinding head 25 to rotate to grind the cutting seam of the template. This way can avoid the harm of burrs to the staff when the staff carry the template. During the cutting process, the exhaust fan 41 pumps the nearby air, and the dust generated during the cutting process enters the interior of the mounting cover 4 through the protective net 43. After that, the air is discharged after being filtered by the filter plate 42, and the dust stays in the interior of the mounting cover 4. This way can effectively reduce the dispersion of dust during the cutting process and ensure the environment of the cutting site.
