Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete formwork removal device. Background Art

[0002] During the construction of modern building projects, it is necessary to build ground and underground water drainage systems in the construction area. In the underground water circulation project, trenches need to be excavated for water drainage. When the trenches are constructed, the side walls of the trenches need to be reinforced and fixed with concrete. When pouring concrete, in order to ensure its beautiful appearance and rapid shaping, concrete formwork needs to be used for shaping and reinforcement. After the early strengthening and shaping of the concrete, the formwork needs to be removed as soon as possible to speed up the construction. During this process, a special demolding device is required for demolding the concrete.

[0003] The existing concrete formwork removal device has a relatively single goal of removing the formwork. However, when removing the formwork of the groove side wall concrete, since concrete formwork is installed on both sides of the groove, the ordinary formwork removal device needs to alternately change the direction of the two sides to perform the removal operation, which is very troublesome, time-consuming and labor-intensive to operate. In this regard, this design proposes a concrete formwork removal device. Utility Model Content

[0004] The purpose of the present invention is to provide a concrete formwork removal device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a concrete formwork removal device, comprising a mounting frame and a formwork removal mechanism installed on the inner wall of the mounting frame;

[0006] The demoulding mechanism includes push plates installed at both ends of the inner wall of the mounting frame, sleeves are inserted at the upper edges of one side of the two push plates, scrapers are fixed at the lower edges of the other sides of the two push plates, support frames are installed at the upper edges of one side of the two push plates, and the inner walls of the two support frames pass through the inner walls of the two push plates and are connected to the inner walls of the connecting sleeves respectively, a connecting frame is installed on one side of the top of the two support frames, a connecting rod is rotatably connected between the two connecting frames, and a hydraulic rod is rotatably connected between the two sides of the two connecting rods.

[0007] In one example, a connecting groove is opened in the middle position of the top of the mounting frame, and the outer walls of one end of the two push plates are slidably connected to the inner walls at both ends of the connecting groove respectively, and a sliding rod is installed in the middle position of the inner wall of the connecting groove.

[0008] In one example, outer walls at both ends of the sliding rod are respectively interlaced and connected with inner walls of the two support frames and inner walls of the two sleeves.

[0009] In one example, limiting grooves are provided on both sides of the inner wall of the connecting groove, limiting sliders are fixed on both sides of the outer walls of the two push plates, and the outer walls of the two limiting sliders are slidably connected to the inner walls of the two limiting grooves respectively.

[0010] In one example, movable bases are installed on both sides of the bottom of the mounting frame, movable wheels are installed at both ends of the bottom of the two movable bases, and a handle is fixed at the upper edge of one side of the mounting frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging a demolding mechanism on the mounting frame, and connecting the two ends of the bottom of the mounting frame through a movable base, when removing the concrete formwork on the side wall of the groove, the mounting frame and the movable base are controlled by the handle to move to the top of the groove, and the hydraulic rod is started to retract and fold the connecting rod, thereby moving the push plate and the scraper closer to each other, squeezing the protruding edge of the formwork on the side wall of the groove, and as the connecting rod folds, the scraper can easily and quickly squeeze the formwork away from the concrete side wall, and there is no need for the staff to operate the demolding equipment to alternately move the two sides of the groove to demold, which reduces the demolding burden of the staff and improves the demolding efficiency.

While moving, since the two ends of the limiting slide 3 are slidably connected to the push plates 201 and are slidably connected to the slide rod 209 through the sleeve 202 thereon, the hydraulic rod 207 is started to make the connecting rod 206 begin to fold and shrink, and then pull the connecting frame 205 to make the mounting frame 1 slide with the push plate 201 on the slide rod 209, so that the scraper 203 at the bottom of the push plate 201 approaches each other and squeezes above the two sides of the groove, squeezing the edge of the concrete template pushed out by its side wall, thereby removing the templates on the two side walls of the groove together, and there is no need for the staff to operate the demoulding equipment to move alternately on both sides, which reduces the burden of demoulding on the staff and also improves the demoulding efficiency.
