Description

A kind of concrete sandwich parts

(1) technical field

The present invention relates to a kind of concrete sandwich parts.

(2) background technology

The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, this floor structure has advantages such as speed of application is fast, cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, be unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (hollow, solid).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased expense, and the speed of application that slowed down, prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib floor structure " utility model patent, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is horizontal positioned at interval, on prefabricated plate, be fixed with formwork, formwork comprises upper plate and side plate on every side, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connect as one with dark rib, this kind floor structure no longer needs to use in a large number template, accelerate speed of application, shortened the duration, thereby reduced cost.But after this shuttering member was applied to cast-in-situ concrete hollow floor, formed superstructure will inevitably be installed component and fittings such as various circuits, often need punch on the superstructure of newly repairing and get into the cave, and difficulty is installed, and repaired very trouble.Therefore, develop a kind of novel concrete and be urgent need with sandwich parts.

(3) summary of the invention

The object of the present invention is to provide a kind of concrete sandwich parts, have simple in structure, convenient transportation, cost of transportation is low, take that work plane is little, assembly unit is convenient, intensity is high, rigidity greatly, characteristics such as cracky not.

Solution of the present invention is on the basis of existing technology, comprises boxboard, following boxboard, is clipped in the filling mould between boxboard and the following boxboard, and it is characterized in that filling mould is the ring frame mould, and the ring frame mould is formed by connecting at least two templates.Like this, filling mould is the ring frame mould, the ring frame mould is formed by connecting at least two templates, make concrete convenient for production with sandwich parts, make simple, be easy to assembly unit, improved efficiency of construction, simultaneously, simple in structure, characteristics such as intensity is high, resistance to deformation, the anti-vibration performance is good, making is easy, production efficiency is high, cost is low that sandwich parts also has, thereby reached purpose of the present invention, be applicable to that hollow building cover, roof system, body of wall, sole plate and the hollow bridges of various cast-in-situ reinforced concretes or prestressed reinforced concrete used, be particularly useful for hollow arch without beam and use.
