Embodiment Construction
[0019] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0020] A dustpan opening device for a structural column support mold, comprising a dustpan opening oblique baffle 1, concave steel plate 2, hypotenuse steel bar baffle 3, triangular baffle 4, sealing steel bar 5, hinge 6, concave steel plate 2 and both sides of the concave groove The baffles are connected by welding, the inclined baffle 1 of the dustpan mouth is connected with the concave steel plate 2 through the hinge 6, and the sealing steel bar 5 is inserted into the baffles on both sides after the concrete pouring is completed, and the baffles on both sides of the concave groove are two isosceles right-angled triangle steel plates 7. The hypotenuse of the triangular steel plate 7 is welded to the hypotenuse steel bar baffle 3. A gap 8 is reserved on the right-angled side of the steel plate close to the concave groove, and two triangular steel plates 7 are we...

The invention relates to a dustpan opening device of a constructional column formwork of a secondary structure. The dustpan opening device comprises a dustpan opening inclined baffle plate, a concavesteel plate, a hypotenuse steel bar baffle plate, a triangular baffle plate and opening sealing steel bars, wherein the concave steel plate is connected with baffle plates arranged at the two sides ofa concave groove through welding; the dustpan opening inclined baffle plate is connected with the concave steel plate through a hinge; and the opening sealing steel bars are inserted into the baffleplates at the two sides after concrete pouring is finished. The invention also provides a construction method of the dustpan opening device. According to the method, firstly, a proper amount of concrete is poured on the dustpan opening inclined baffle plate in an open state; next, the dustpan opening inclined baffle plate is closed, the opening sealing steel bars are inserted into notches, and theconcrete is compactly extruded; and finally, when the concrete reaches the strength capable of enabling the concrete surface not to be damaged through formwork dismantling, the formwork is dismounted. The dustpan opening device of the constructional column formwork is used in a recycled mode; the technical problem that the concrete at the upper part of a constructional column is not compact is solved; and the dustpan opening device is safe and reliable and is convenient for application and popularization.
Description
technical field [0001] The invention belongs to the field of construction, in particular to a dustpan mouth device and a construction method of a secondary structure structural column formwork support. Background technique [0002] Most civil or industrial buildings involve secondary structures, which require structural columns. In the past, the formwork of the structural columns was provided with a dustpan opening for the upper part of the structure. After the concrete hardened, the excess corbel part of the concrete was manually chiseled. This conventional method easily causes the concrete in the upper part of the structural column to be not dense, wastes concrete, and takes labor to remove the concrete, which affects the construction period. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a dustpan opening device for supporting the formwork of the secondary structure construction column. [000...
