[0025] The features and performance of the chiseling-free and reusable dustpan mouth device for structural columns and the method of use of the present application are further described in detail below in conjunction with the embodiments.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides a structural column dustpan opening device that is reusable and does not require chiseling, and includes a wall plate 100 for being fitted and fixed on a masonry wall, a pair of vertical baffles 110, an oblique baffle 120 and three latches 130. A square feed port 111 is provided in the middle of the top of the wall plate 100, a pair of vertical baffles 110 are respectively connected to one side surface of the wall plate 100 and are respectively located on both sides of the feed port 111, and the bottom of the oblique baffle 120 is hinged to the bottom of the feed port 111 of the wall plate 100 through two hinges 190. The oblique baffle 120 opens or closes the feed port 111 when it rotates, and the two sides of the oblique baffle 120 slide against the two vertical baffles 110 when it rotates; four bolt holes 140 are provided on the wall plate 100 for connecting it to the masonry wall. The ends of the two vertical baffles 110 close to the wall plate 100 are respectively provided with three fixing holes 150 arranged at intervals in the height direction, and the fixing holes 150 on the two vertical baffles 110 correspond to each other. When the latch 130 passes through the corresponding fixing holes 150 on the two vertical baffles 110 in sequence, it blocks the oblique baffle 120 that closes the feed port 111. The middle parts of the two vertical baffles 110 are respectively provided with three spaced limiting holes 160, and the limiting holes 160 on the two vertical baffles 110 correspond to each other. When the latch 130 passes through the corresponding limiting holes 160 on the two vertical baffles 110 in sequence, it supports the oblique baffle 120 arranged at a 45-degree angle with the wall plate 100. One end of each latch 130 is connected to a limiting stopper 170, and the end of the oblique baffle 120 away from the wall plate 100 is connected to a handle 180.

[0027] The present application also provides a method for using the above-mentioned structural column dustpan opening device that can be recycled without chiseling, including the following steps:

[0028] Step 1: Attach the wall plate 100 to the reserved position on the masonry wall, and insert four connecting bolts through the four bolt holes 140 on the wall plate 100 to connect and fix it to the masonry wall;

[0029] Step 2: Hold the handle 180 and rotate the oblique baffle 120 to open the feed port 111, and rotate the oblique baffle 120 to be arranged at a 45-degree angle with the wall plate 100. Pass the three latches 130 through and connect the three pairs of limit holes 160 on the two vertical baffles 110, so that the three latches 130 respectively support the oblique baffle 120 arranged at a 45-degree angle with the wall plate 100. At this time, pour concrete onto the oblique baffle 120, so that the concrete flows steadily along the oblique baffle 120 and flows into the inside of the masonry wall through the feed port 111. Use a vibrator to vibrate the concrete until the concrete fills the internal space of the masonry wall.

[0030] Step three, hold the handle 180 and rotate the oblique baffle 120 until it is embedded in the feed port 111 to completely close the feed port 111. After pulling out the three pins 130 from the three pairs of limit holes 160 on the two vertical baffles 110, respectively, re-pass the three pins 130 through and connect to the three pairs of fixing holes 150 on the two vertical baffles 110, so that the three pins 130 block the oblique baffle 120 that closes the feed port 111. After the concrete strength reaches the requirement, remove the four connecting bolts to separate the wall panel 100 from the masonry wall, and repeat the above steps to attach the wall panel 100 to another masonry wall to continue the operation.

[0031] The chiseling-free and reusable dustpan opening device for structural columns provided in the embodiment of the present application is provided with a wall plate 100 that can be fitted and connected to the masonry wall, a feed opening 111 and an oblique baffle 120 that can be rotated to open and close the feed opening 111 are provided on the wall plate 100, and a pair of vertical baffles 110 connected to the wall plate 100 and located on both sides of the oblique baffle 120 are provided, and corresponding fixing holes 150 and limiting holes 160 are provided on the two vertical baffles 110, so that the operator can rotate the oblique baffle 120 to open and close the feed opening 111 and selectively insert the plug The pin 130 passes through the limiting hole 160 or the fixing hole 150 to support the inclined baffle 120 arranged at a preset acute angle with the wall plate 100 or the inclined baffle 120 that blocks the closed feed port 111, thereby respectively fixing the inclined baffle 120 arranged at a preset acute angle with the wall plate 100 or the inclined baffle 120 embedded in the feed port 111, thereby ensuring stable concrete pouring operations and closing and waiting for concrete to solidify. It has the advantages of saving manpower and material resources, low carbon and environmental protection, can improve the molding quality of concrete pouring, is easy to operate, and can be recycled.

[0032] In other optional embodiments, elastic sealing strips are respectively provided on both sides of the oblique baffle 120. When the oblique baffle 120 rotates, the sealing strips on both sides slide and press against the two vertical baffles 110 respectively. By respectively providing elastic sealing strips on both sides of the oblique baffle 120, when the oblique baffle 120 rotates, the two sides can be better elastically sealed with the two vertical baffles 110 through the sealing strips, thereby ensuring the stable rotation of the oblique baffle 120 while ensuring the sealing performance, thereby effectively preventing leakage of slurry between the oblique baffle 120 and the vertical baffle 110 during the pouring of concrete.

[0033] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
