Description

Technical Field

[0001] The utility model relates to the technical field of bay window moulds, in particular to a bay window base mould. Background Art

[0002] Bay windows are exterior windows that extend beyond the building's facade, expanding interior space, broadening views, and enriching the building's facade. Most bay windows are prefabricated, primarily using cast-in-place reinforced concrete. During production, reinforced concrete is poured into a mold. Once the concrete solidifies, the prefabricated bay window is removed and transported to the construction site for installation.

[0003] The Chinese patent (authorization announcement number: CN 213471611 U, authorization announcement date: 2021.06.18) proposes a bay window forming mold, which fixes the outer mold through an isosceles ladder-shaped external connecting mold and connects the inner mold through an isosceles ladder-shaped internal connecting mold to facilitate later demolding; reinforcing ribs are set on the inner and outer molds to further increase the overall structural stability of the bay window forming mold; the internal grooves of the bay window forming mold do not affect the forming of the bay window prefabricated panels, reduce weight, and facilitate disassembly and assembly.

[0004] When the above-mentioned bay window mold is used to produce prefabricated bay windows, multiple side molds are first fixed on the bottom mold by bolts, and then reinforced concrete is poured into the side molds. After the concrete solidifies and takes shape, the bolts on the side molds are turned to remove them, and then the molds are demoulded to complete the production of the prefabricated bay windows. Therefore, the overall steps of disassembling and assembling the bay window mold are too cumbersome, which greatly affects the production efficiency of the prefabricated bay windows. In addition, the disassembly and assembly of the mold has high requirements for the installation workers, and unevenness may occur during installation, affecting the flatness of the prefabricated bay windows. For this reason, we propose a bay window base mold. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a bay window base mold, which installs a sliding assembly between the long outer mold and the short outer mold and the base. When assembling the bay window outer mold, the long outer mold and the short outer mold are pushed by the handle. Since the long outer mold and the short outer mold are fixedly installed on the sliding block of the sliding assembly by bolts, the sliding block is pushed to slide inward on the sliding groove one, and the top plate is pressed against the sliding block by the action of the spring, and then the screw rod three is rotated to make the top tightening plate threadedly connected to the rotating screw rod three press against the sliding block, thereby completing the fixation of the long outer mold and the short outer mold. When disassembling the bay window outer mold, the screw rod three is rotated so that the top tightening plate no longer presses against the sliding block, and then the handle is pulled. At the same time, the rebound force of the spring also pushes the long outer mold and the short outer mold outward, thereby completing the bay window. The demoulding of the outer mold is simple and easy, which improves the production efficiency of the bay window mold. Support components are installed at the four corners of the base. The support legs are adjusted to rise and fall by screw 2 in the support component to quickly level the base to avoid the unevenness of the base affecting the flatness of the prefabricated bay window. The bay window inner mold is composed of two groups of inner short side molds, two groups of inner long side molds and four groups of inner corner molds, which makes it easy for the device to disassemble the bay window inner mold. The position of the inner corner mold is fixed by installing a limiting component between the long outer mold and the short outer mold and the inner corner mold.

Then, the screw rod 3 23 is rotated by the outer hexagonal head 1 25. Due to the top plate 24 threadedly connected to the screw rod 3 23, the top plate 24 slides inwardly on the sliding groove 2 22, and under the action of the spring 27, the top plate 28 presses the inner side of the sliding block 6, thereby completing the fixed assembly of the long outer mold 2 and the short outer mold 3, so that they are enclosed into the outer mold of the bay window. Then, Assemble two sets of inner short side molds 15, two sets of inner long side molds 16 and four sets of inner corner molds 14 to enclose the inner mold of the bay window, and fix the distance between the short outer mold 3 and the inner corner mold 14 and the distance between the long outer mold 2 and the inner corner mold 14 by the limiting rod 29, so as to complete the position fixation of the inner corner mold 14, and rotate the screw 12 by the outer hexagonal head 2, and tighten the two sets of mounting plates 31 by the action of the nut 13, thereby tightening the long outer mold 2 and the inner long side mold 16 and the short outer mold 3 and the inner short side mold 15, avoiding Due to the extrusion deformation caused by the pouring of reinforced concrete, after the pouring of reinforced concrete is completed, the screw three 23 is rotated by the external hexagonal head 25, so that the tightening plate 24 slides outward on the sliding groove 22, and then under the rebound action of the spring 27, the top plate 28 applies force to the sliding block 6, and at the same time pulls the handle 34 to complete the rapid demoulding of the long outer mold 2 and the short outer mold 3. Since the bay window inner mold is composed of multiple groups of molds, its disassembly is more convenient. The demoulding process is simple and easy, which improves the production efficiency of the bay window mold.
