During the use, establish the sleeve pipe cover that the internal diameter and apron 82 external diameter suited under with on apron 82 and the upper cover plate 83 preliminary fixed, then rotate the required position at horizontal plate 211 with the sleeve pipe is fixed to fixed column 81, prevent to pour in-process sleeve pipe emergence skew. The shroud 84 covers the upper opening of the casing, reducing the likelihood of casting material entering the casing.

Referring to fig. 20, the preformed hole positioning assembly 9 includes a hollow circular truncated cone-shaped mold column and a fixing rod 91 coaxially penetrating through the mold column, the mold column is composed of a forming tube 94, an upper sealing plate 92 fixed at one end of the forming tube 94 and a lower sealing plate 93 fixed at the other end of the forming tube 94, the outer diameter of the outline of the forming tube 94 is gradually reduced from the upper sealing plate 92 to the lower sealing plate 93, and the preformed hole positioning assembly 9 is conveniently pulled out after pouring is finished. The fixing rod 91 may here be a screw for fixing the mold column to the horizontal plate 211 of the bottom mold 2. The outer wall surface of the forming pipe 94 is smooth, a layer of release agent can be brushed before use, and labor is saved when the forming pipe is pulled out.

A construction method of a balcony prefabricated mould comprises the following steps:

(1) assembling a mold: the bottom mould 2 is supported on the platform such that the horizontal plate 211 of the bottom mould 2 is placed horizontally and then the fenders 61 of the two end moulds 6 are supported horizontally on the horizontal plate 211 such that the face beam end mould assembly 62 is located below and adjacent to the support plate 212 and the breast board end mould assembly 63 is located above. The top die 5 is supported on the horizontal plate 211, and both ends of the top die 5 are respectively abutted against the surrounding barriers 61 on both sides. The sideform 3 is then placed vertically and against the facia end module 62 and the breast board end module 63. The working surface of the table mouth mold 4 is attached to the breast board end mold assembly 63, and the first folding board 42 is abutted to the enclosure 61. All the modules are fixedly connected through bolts. And then the notch die 7 is clamped and tightly propped against the corner part of the top die 5 connected with the end die 6. The sleeve positioning component 8 and the reserved hole positioning component 9 are installed at the positioning hole of the horizontal plate 211.

(2) Pouring for one time: and pouring the building material which is uniformly stirred from the opening on the bottom die 2, spreading the building material on the horizontal plate 211, and simultaneously, allowing a part of the building material to enter a die cavity enclosed by the bottom die 2, the side dies 3 and the surface beam end die assembly 62 along the opening between the table die 4 and the bottom die 2. When the building material reaches the upper plane of the surround 61, the casting is stopped. Then, the building material is tamped by the vibrator, and if the building material sinks to a high degree, the building material is additionally poured, and then the building material is moved from one end to the other end along the second thickened side plate 55 of the top die 5 by the scraper and is leveled, and the building material is kept standing for solidification.

(3) Secondary pouring: and (3) starting secondary pouring after the building material on the bottom die 2 is primarily solidified, wherein the interval time is determined according to the solidification speed of the building material and is generally not less than 15 minutes, and pouring into the die cavity between the opening die 4 and the side die 3 is started when the solidification strength of the building material reaches 30% of the final strength. Therefore, the opening between the table mouth mold 4 and the bottom mold 2 is plugged due to the primary solidification of the once-poured building material, and the material for secondary pouring is prevented from overflowing.

(4) Removing the mold: after the building materials on the bottom die 2 are hardened, the sleeve positioning assembly 8 and the reserved hole positioning assembly 9 are taken down from the prefabricated balcony 1, then bolts connected among the opening die 4, the side die 3, the top die 5 and the end die 6 are disassembled, lifting tools are used for pulling all parts of the die to be disassembled from the side, and the notch die 7 is disassembled from the corner of the prefabricated balcony 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
