Description

Mould for layered pouring sandwich heat-insulating wallboard Technical Field The utility model relates to a template, in particular to a die for layered pouring of sandwich heat-insulating wallboards. Background The prefabricated concrete sandwich heat-insulating wallboard is simply called sandwich heat-insulating wallboard, and is of a three-layer structure and comprises an inner layer, an intermediate layer and an outer layer. The inner layer is adjacent to the indoor space and is called an inner leaf concrete wallboard, which is called an inner leaf wallboard for short. The outer layer is adjacent to the outside and is called an outer leaf concrete wallboard, which is called the outer leaf wallboard for short. The middle layer is positioned between the inner layer and the outer layer, plays a role in heat preservation and is a sandwich heat preservation layer. And a plurality of drawknot pieces are further arranged between the inner layer and the outer layer and used for improving the integrity of the sandwich heat-insulating wallboard three-layer structure. The pouring mode of the sandwich heat-insulating wallboard comprises two modes of integral pouring and layered pouring. During integral casting, the plane corresponding to the sandwich heat-insulating wallboard is vertical, the middle layer is fixed in the die, and then the inner layer and the outer layer are cast simultaneously. The integral pouring has the advantages of high speed and high mould manufacturing requirement, and concrete is difficult to vibrate and compact. When the sandwich heat-insulating wallboard is poured in a layered mode, the corresponding plane of the sandwich heat-insulating wallboard is horizontal, any one layer (a pre-pouring layer) of the inner layer and the outer layer is poured firstly, after the pre-pouring layer reaches a certain strength, an intermediate layer is paved and fixed on the top surface of the pre-pouring layer, and then the other layer (a post-pouring layer) is poured on the top of the intermediate layer. The layered pouring has the advantages of easy formwork support and convenient concrete vibrating. The disadvantage of layered casting is mainly that the casting time is long, and after the prior casting layer reaches a certain strength, the middle layer is installed and the post-casting layer is cast. If the intermediate layer is installed and the post-cast layer is poured under the condition of insufficient strength of the pre-cast layer in order to shorten the pouring time, the intermediate layer is a heat insulation material with low density and low strength, the heat insulation material cannot be well supported by the pre-cast layer, the heat insulation material is easy to crack, when the concrete of the post-cast layer is vibrated, the heat insulation material is easy to float and enter the post-cast layer, and a small part of heat insulation material is possibly embedded into the pre-cast layer, so that the quality of the sandwich heat insulation wallboard is influenced. After the pre-cast layer reaches a certain strength, the intermediate layer is installed and the post-cast layer is poured, the intermediate layer can be well supported by the pre-cast layer, but the intermediate layer is still difficult to fix, the intermediate layer is disturbed by concrete of the post-cast layer after vibrating, and is still easy to break and float, so that the thickness of the post-cast layer is insufficient. In addition, when sandwich heat preservation wallboard is layered and poured, in order to control the thickness of the layer of watering earlier, mark with the pen around the template generally, whether through observing the surface of layer of watering earlier and mark to be leveled in the pouring process, with the thickness of control layer of watering earlier, this kind of method relies on the naked eye to observe, and the error is great, especially for the sandwich heat preservation wallboard that the area is great. The pipeline can be arranged in the sandwich heat-insulating wallboard, and because the inner layer and the outer layer are both of reinforced concrete structures, the pipeline is difficult to be arranged in a slotting mode, and the pipeline can be arranged on the inner surface or the outer surface of the sandwich heat-insulating wallboard only. Disclosure of utility model The utility model provides a die for layered pouring of sandwich heat-insulating wallboards, which solves the problems that the layered pouring of sandwich heat-insulating wallboards takes long time and a sandwich heat-insulating layer is not easy to fix during pouring. The technical scheme includes that the die for layered pouring of the sandwich heat-insulating wallboard comprises side templates, wherein the side templates are vertically arranged and enclose a pouring cavity with an open top, an upper layer of connecting pipes and a lower layer of connecting pipes are arranged in the pouring cavity and fixedly connected
