Truss rib laminated plate with height limiting devices, die table assembly and production process thereof

Abstract

The invention belongs to the technical field of fabricated buildings, and particularly relates to a truss rib laminated plate with height limiting devices, a die table assembly and a production process thereof. The truss rib laminated plate with the height limiting devices comprises a prefabricated bottom plate and a cast-in-place layer. A plurality of height limiting devices are embedded in the prefabricated bottom plate. The height limiting devices and truss ribs on the prefabricated bottom plate are located on the same side. The height of each height limiting device exposed outside the prefabricated bottom plate is equal to the thickness of the cast-in-place layer. Each height limiting device comprises a height limiting pier, and the height limiting piers and the prefabricated bottom plate are poured to from an integral structure. According to the truss rib laminated plate, the height limiting piers and the prefabricated bottom plate are poured together, so that a slab thickness control point can be accurately determined; cast-in-place layer concrete is flush with the height limiting piers, and design requirements are met; and in addition, on storage and transportation stackingfulcrums, the precision is high, the strength is high, force is transmitted up and down, and neither the truss ribs nor a bottom plate body is damaged.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a truss bar laminated plate with a height limiting device, a mold platform assembly and a production process thereof. Background technique [0002] Laminated slab is a commonly used component form in the field of prefabricated construction engineering. It refers to that the reinforced concrete components are prefabricated in a factory in one step, and the other part is cast-in-place and laminated at the construction site to form a laminated slab. The laminated slab includes the bottom slab and the cast-in-place layer. The bottom slab is also used as a permanent formwork during construction and is also a part of the stressed structural member. The laminated slab generally refers to the prefabricated bottom slab. The basic requirements for the superposition of the prefabricated floor and cast-in-place concrete are that the contact surface should firstly ...

AI Technical Summary

Problems solved by technology

[0013] The truss bars and stressed floor of the existing laminated slab structure are not fully protected, and are easily deformed and cracked during storage and transportation; during storage and transportation, either the bottom plate presses the truss bars or the bottom plate Either method of pressing the bottom plate will cause damage to the laminated plate, either the truss tendon is damaged or deformed, or the bottom plate is cracked

In short, there are hidden dangers in the production, storage, transportation and installation of existing laminated panels.
