Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand the invention and to implement the invention, and are not intended to limit the scope of the invention in any way.

Referring to fig. 1 to 5, an embodiment of the present invention provides a prefabricated exterior wall mold, including a cast-in-place cavity module 100, where the cast-in-place cavity module 100 is used to construct a cast-in-place cavity at the bottom of a prefabricated exterior wall, and after the whole prefabricated exterior wall mold is formed by pouring concrete, the cast-in-place cavity module 100 needs to be drawn out from the whole mold. The cast-in-place cavity module 100 comprises a box-like body 1 of substantially square shape, the box-like body 1 having a cavity therein. The vertical face of the box-like body 1 is provided with projections 2 so as to form a space for accommodating vertical ring-shaped reinforcing bars 3 in the prefabricated outer wall. In this embodiment, the projections 2 are arranged at intervals of 6 along the length direction of the box-

like body

1, 3 on the front vertical surface and 3 on the back inner surface. The vertical ring-shaped reinforcing bar 3 includes two vertical sections 301 located inside the protrusions 2, and a horizontal section 302 connecting bottom ends of the two vertical sections 301, thereby forming a ring shape, and is referred to as a vertical ring-shaped reinforcing bar 3.

Still be equipped with expansion plate 4 in box-like main part 1, the bottom of expansion plate 4 can be followed the inside of box-like main part 1 stretches out, specifically, can set up the opening on the dorsal part facade with box-like main part 1, makes expansion plate 4 can stretch out from opening department. In this embodiment, the two expansion plates 4 are arranged in parallel and substantially perpendicular to the inside of the box-like body 1. A plurality of reinforcing steel bar grooves 5 are formed on the extending part of the expansion plate 4 in the extending state, and the number of the reinforcing steel bar grooves 5 corresponds to the number of the transverse reinforcing steel bars 6 at the bottom of the cast-in-place cavity. The reinforcing steel bar groove 5 is used for the transverse reinforcing steel bars 6 at the bottom of the prefabricated outer wall to pass through. The expansion plate 4 is also connected with an expansion control mechanism arranged in the box-shaped main body 1, and the expansion control mechanism is used for controlling the expansion plate 4 to do expansion movement inside and outside the box-shaped main body 1. If need horizontal reinforcing bar 6 to stay in the cast-in-place cavity of prefabricated outer wall bottom, when the mould assembly, control expansion plate 4 stretches out from box-like main part 1 bottom, lets horizontal reinforcing bar 6 pass reinforcing bar groove 5, like this when the mould concreting, expansion plate 4 on both sides just has formed to the concrete and has blockked, can't get into in the space between expansion plate 4 to make this section horizontal reinforcing bar 6 between expansion plate 4 just stayed in the cast-in-place cavity. When the cast-in-place cavity module 100 is removed, the control expansion plate 4 is retracted into the box-like body 1, and the whole cast-in-place cavity module 100 is drawn out downward, so that the transverse reinforcing bars 6 are separated from the reinforcing bar grooves 5, and the movement of the cast-in-place cavity module 100 is not hindered.

The top surface of box-like body 1 has the opening that can supply vertical annular reinforcing bar 3 to pass (the opening is for being marked by baffle 7 confined state in fig. 3), and the opening specifically is located the top of protruding 2 parts, has openable baffle 7 on the opening, and baffle 7 passes through baffle pivot 16 to be connected at the top surface of box-like body 1. In the die assembling process, the flap 7 is in an open state, and the vertical ring-shaped reinforcing bars 3 can be put into the box-like body 1 through the opening. Then the baffle 7 is closed to block the concrete during casting. After concrete pouring is finished, basically forming the prefabricated outer wall, then removing the formwork, enabling the whole cast-in-place cavity module 100 to move downwards, enabling the horizontal section 302 at the bottom to be in contact with the baffle 7, pushing the baffle 7 open, smoothly removing the cast-in-place cavity module 100, and not blocking the movement of the cast-in-place cavity module 100.

In this embodiment, each expansion plate 4 corresponds to a group of expansion control mechanisms, each expansion control mechanism comprises a support 8, two expansion control mechanisms are arranged at the upper part and the lower part, a transmission shaft 9 is arranged on each support 8, the transmission shafts 9 are arranged along the height direction of the box-shaped main body 1, and gears 10 (two expansion control mechanisms are arranged at the upper part and the lower part) are sleeved on each transmission shaft 9 and can rotate along with the transmission shafts 9; the side of expansion plate 4 is fixed with rack 11, and gear 10 and rack 11 mesh for when transmission shaft 9 rotated, can drive gear 10 and rotate, utilize gear 10 to drive rack 11 and reciprocate, finally drive expansion plate 4 inside and outside reciprocating motion in box-like main part 1. In some embodiments, the transmission shaft 9 is sleeved with a spring 12, which can provide a torsion force to save an external force applied when the transmission shaft 9 is rotated.

The lower end of the drive shaft 9 can extend from the bottom of the box-like body 1 and is provided with a flange structure 13 at the extending portion, and the flange structure 13 can be used for connecting with various driving devices, such as a driving motor and the like, thereby improving the automation degree.
