Description

Technical Field

[0001] The utility model relates to concrete precast part production equipment, in particular to a combined mold for casting precast wall panels. Background Art

[0002] The wall panels of prefabricated houses are precast wall panels. After being manufactured in the factory, the precast wall panels are transported to the site and directly assembled with beams, etc., which can improve the house construction efficiency. The sizes (length and width sizes) of each precast wall panel are basically different, and the side shapes are also different. For example, some are flat, some have splicing grooves, and some have splicing ridges. The traditional casting method for precast wall panels is that casting molds need to be separately designed and manufactured for precast wall panels with different sizes and shapes, resulting in higher costs.

Specific embodiments

[0028] The following will refer to the accompanying drawings to describe the preferred embodiments of the present utility model in detail. It should be understood that the preferred embodiments are only for explaining the present utility model and not for limiting the protection scope of the present utility model.

[0029] Embodiment 1

[0030] As Figures 1 - 6 shown, a combined mold for precast wallboard casting includes a standard mold table. A side mold is provided on the standard mold table. The side mold is composed of side molds 1 on each side and universal adapters 2 between side molds 1. The side mold 1 is formed by splicing one side mold unit 3 or more than one side mold unit 3 in the length direction. For precast wallboard casting with different sizes (length and width sizes), there is no need to separately design and manufacture the mold. It only needs to be composed of a universal adapter 2 and a side mold unit 3, which can greatly reduce the mold cost.

[0031] The side mold units 3 are divided into three types according to their shapes: side mold units 3 with a flat inner side, side mold units 3 with a convex rib 4 in the length direction on the inner side, and side mold units 3 with a groove 5 in the length direction on the inner side. For precast wallboard casting with different sizes and different side shapes, the corresponding shaped side mold units 3 are selected and spliced through the universal adapter 2.

[0032] There are grooves in the length direction on the outer side of the side mold unit 3, and several reinforcing plates 17 are vertically arranged at uniform intervals in the length direction in the grooves.

[0033] The top surface of the groove is evenly spaced with strip holes along the length direction of the groove. One end of the I-shaped fixing piece is connected to the strip hole by a bolt, and the other end is connected to the embedded part by a bolt. The embedded part is located inside the side formwork.

[0034] The general adapter 2 is a hollow regular quadrangular prism with an open outside. The two sides of the regular quadrangular prism general adapter coincide with the groove end faces of the side formwork units 3 on both sides and are connected by bolts.

[0035] Adjacent side formwork units 3 are connected by bolts.

[0036] On the inner side of the side formwork on the upper side of the standard formwork table, there is an inner formwork for forming the door and window installation opening 6. The inner formwork is composed of the inner side formworks 7 on each side and the general inner adapter 8 between the inner side formworks 7. The inner side formwork 7 is composed of one inner side formwork unit or more than one inner side formwork unit spliced together. When casting the precast wall panel facing the door and window installation opening 6, the inner formwork casting is adopted. For the formation of door and window installation openings 6 with different sizes (length and width dimensions), it is formed by splicing the inner side formwork units and the general inner adapter 8.

[0037] There are grooves on the inner side of the inner side formwork unit in the length direction, and several reinforcing plates are vertically arranged at uniform intervals in the length direction in the grooves.

[0038] The general inner adapter 8 is a hollow right-angle structure with an open inside. The two end faces of the right-angle structure general inner adapter 8 coincide with the groove end faces of the inner side formwork units on both sides and are connected by bolts.

[0039] Adjacent two inner side formwork units are connected by bolts.

[0040] The side formwork unit 3 is a side formwork unit with a common length, and the inner side formwork unit is an inner side formwork unit with a common length. The lengths of the side formwork unit with a common length and the inner side formwork unit with a common length are determined according to the basic dimensions of the house and experience. Of course, for some special requirements, side formwork units with customized lengths can also be added. At this time, the side formwork is composed of side formwork units with a common length and side formwork units with a customized length. The following table reveals a set of data including side formwork units with a common length, inner side formwork units with a common length (light gray), and side formwork units with a customized length (dark gray):

[0041]

[0042] The molds required for 90% of the precast wall panels can be combined with side formwork units with a common length, inner side formwork units with a common length (light gray), the general adapter 2, and the general inner adapter 8. Adding side formwork units with a customized length can basically meet the mold requirements for all precast wall panel castings.

[0043] Embodiment 2

[0044] As Figures 2 - 3As shown, the difference from the first embodiment is that when casting precast wall panels of the same size and forming embedded parts thereon, an embedded part positioning frame 9 is detachably arranged between the opposite sides of the side mold, and an embedded part 10 that can extend into the side mold is connected to the embedded part positioning frame 9.

[0045] When casting precast wall panels of different sizes and forming embedded parts thereon, the embedded part positioning frame 9 includes a cross bar 11, and a plurality of movable connecting parts 12 are arranged on the cross bar 11. Preferably, the connecting part 12 is a connecting sleeve, and the connecting part 12 and the cross bar 11 can be locked by a locking part 13. The locking part 13 is a locking screw, and a threaded hole for cooperating with the locking screw is arranged on the connecting sleeve. Support rods 14 are respectively connected to the two connecting parts 12 at both ends of the cross bar 11, and the other ends of the two support rods 14 are respectively detachably installed on the opposite sides of the side mold through installation parts. The installation part includes a clamping opening 16 that can clamp the top surface of the groove of the side mold 1 with an open side. A threaded hole is arranged on the top surface of the clamping opening 16, and a tightening screw 13 is arranged in the threaded hole. A vertical rod 15 is connected to the connecting part 12 in the middle of the cross bar 11, and the other end of the vertical rod 15 is connected to an embedded part 10 that can extend into the side mold.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
