Embodiment Construction
[0032] The invention will be further described below in conjunction with the accompanying drawings.
[0033] figure 1 It is a schematic diagram of the structure of the lightweight filler mandrel of the present invention. The light-weight filler mandrel 1 is composed of a flame-retardant polystyrene 2, an elastic gelled mixture protective layer 5 and a mesh cloth 6 in cross-section, wherein the flame-retardant polystyrene 2 has a through hole 3 in the center, and an oblique hole 3 on the bottom side. side 4.
[0034] In the process of making the lightweight filler mandrel 1, first paint a layer of elastic gelling mixture protective layer 5 on the entire surface of the flame-retardant polystyrene 2, then spread the mesh cloth 6, and then cover the mesh cloth 6 with a coating Brush the protective layer of elastic gel mixture to form an effective protective layer. The through hole 3 is used to observe the concrete density at the bottom of the mandrel 1 of the lightweight filler ...

The invention discloses a light filled core formwork used for a hollow floor. The light filled core formwork used for the hollow floor comprises inner core flame-retardant polystyrene and an elastic gel mixture. The surface of the whole inner core flame-retardant polystyrene is wrapped with the elastic gel mixture, so that a waterproof protection layer for overall protection is formed. The elasticgel mixture is prepared by mixing and stirring vinyl acetate suspension liquid, cement, water, silicon powder, and the like in a certain proportion. A vertical through hole of the light filled core formwork is drilled through a self-made drilling device, and bevel edges of the bottom surface of the light filled core formwork are formed by a self-made bevel edge sleeving device and a bevel edge cutting device jointly. Compared with similar products of hollow floors, the light filled core formwork has the advantages of good waterproof performance and fireproof performance, low weight, zero breakage rate, good overall performance, easy and convenient construction, and the like; and more preferably, the structural design principle of drawings can be effectively guaranteed in the constructionprocess through a hollow cover, and the construction quality and the structural safety are guaranteed.
Description
technical field [0001] The invention relates to a lightweight filler mandrel for a hollow floor, in particular to a manufacturing method and process flow of the lightweight filler mandrel. Background technique [0002] The hollow floor is usually formed by filling the mandrel, the upper and lower slab steel bars and the densely ribbed beam steel bar, and then pouring concrete at one time. The mandrel of the filling body of the hollow floor is used as a permanent built-in floor, and it is structurally combined with reinforced concrete to form a cavity and ribbed floor. In terms of form, the mandrel of the filling body does not participate in the structural force, and can replace the hollowed out concrete. Reduce the weight of the building structure and save energy. At present, the built-in filler mandrels of cast-in-place reinforced concrete hollow floors usually include thin-walled cement boxes, thin-walled plastic boxes, thin-walled gypsum boxes, and hollow steel mesh boxe...
