Abstract

The invention provides a combined core die for a cast-in-situ reinforced concrete hollow component, and belongs to combined core dies. The combined core die mainly solves the technical problems that an existing combined core die is high in production cost, complex in forming machining, low in strength, prone to combustion, high in transportation damage and the like. According to the technical scheme, a die body (2) is formed by combining two or more die shoes (6) with the end faces provided with connecting and sealing grooves (3), the two ends of the die body (2) are fixedly connected with plugs (4), and therefore the sealed hollow combined core die (1) is formed. The combined core die for the cast-in-situ reinforced concrete hollow component is mainly applied to civil and public buildings with large spans and large bays.

Description

A kind of cast-in-situ reinforced concrete hollow component composite core formwork

Technical field

The present invention relates to a kind of composite core formwork, particularly a kind of cast-in-situ reinforced concrete hollow component composite core formwork.

Background technology

At present, existing composite core formwork mostly adopt timber or waste or used plastics hot-forming, cost of production is high, processing and forming is complicated, intensity is low, transport is damaged greatly, easy firing, fire-retardant rate are low, the connection of composite core formwork is be wound around by cutting or outer wall mostly, cutting connects Product Precision requirement higher, and inapplicable arc or special-shaped die shoe, outer wall is wound around and requires higher to winding material, sealing is poor, and one-time formed overall core cost of transportation is high.

Summary of the invention

The object of this invention is to provide that a kind of cost is low, intensity is high, the cast-in-situ reinforced concrete hollow component composite core formwork of resistance to burning.

The technical solution adopted for the present invention to solve the technical problems is: the die shoe 6 being provided with through connection sealed groove 3 by the axial limit on two panels or the above mating face of two panels combines die body 2, and die body 2 two ends connect firmly plug 4, form airtight hollow composite core formwork 1.

Die shoe 6 shape is be greater than the dihedral of 75 ° or the dihedral or the circular arc that are greater than 75 ° of band arc section.

Between die shoe 6 connection, be in groove 3, add inserts 5 fill, inserts solidification after die shoe is fixedly connected, be combined into die body 2.

Inserts 5 is organic bond or the inorganic material comprising concrete.

The end surface shape of composite core formwork 1 is square, trapezoidal, rectangle, circle, regular polygon or irregularly shaped.

Die shoe 6 material adopts flyash, gangue, shale, clay or its mixture sintering to form.

1. core plug 4 adapts with die body 2 two ends and coordinates, and is sintered form by flyash, gangue, shale, clay or its mixture, or by cement and cement and organic or inorganic inserts blended shaping.

The invention has the beneficial effects as follows:

Cost of production is low, intensity is high, and overlappingly can be set with pile, cost of transportation is lower by more than 400% than one-time formed overall core.

This composite core formwork can meet vibrating arbitrarily when fluid concrete, and can bear the requirement of building pressure, pulling force, shearing force and torsional forces complicated in design, construction and use procedure.

Resistance to burning, fire-retardant rank is GB building materials A1 grade standard, can meet the requirement of national standard Code for fire protection design of buildings one-level fire endurance.
