Lightweight core mould
A lightweight, core mold technology, applied in the direction of formwork/template/work frame, structural elements, building components, etc., can solve the problem of increasing the section size of cast-in-place concrete ribs, increasing the cost of the floor, and low ability to concentrate loads. And other issues

Problems solved by technology
However, after being applied to the hollow floor, the cast-in-place concrete ribs formed between the cavity formwork members are all rectangular cast-in-place concrete ribs, and their mechanical performance is not very reasonable, so it is often necessary to increase the cross-sectional size of the cast-in-place concrete ribs , increase the amount of steel bars and concrete, and increase the cost of the floor. At the same time, in the evacuated part of the cavity formwork, the strength and stiffness of the hollow floor are relatively poor, and the ability to withstand concentrated loads is relatively low. Therefore, the development of a A new type of lightweight mandrel component has been urgently needed

The invention relates to a lightweight core mould, which comprises a foam-shaped and lightweight component (1) of an inner core. The lightweight core mould is characterized in that the outside of the lightweight component (1) is coated by an isolating layer (2) or / and a separation net (3); the outside of the isolating layer (2) or / and the separation net (3) is / are provided with a stiffened plate (4), a stiffened rod (5) or a stiffened mound (6); the stiffened plate (4), the stiffened rod (5) or the stiffened mound (6) is connected with the isolating layer (2) or / and the separation net (3) or / and a foam component into a whole body; and the isolating layer (2) or / and the separation net (3), the stiffened plate (4), the stiffened rod (5) or the stiffened mound (6) is a supporting layer of the lightweight core mould. Therefore, the lightweight core mould also has the characteristics of simple structure, excellent performance of deformation resistance and vibration resistance, convenient construction, high construction speed and the like, and is suitable to be used in hollow floors, roofs, wall bodies, foundation slabs and spandrel-braced bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete.
Description
(1) Technical field [0001] The invention relates to a lightweight mandrel. (two), background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, and the name is called "combined concrete hidden rib floor cover plate" utility model patent, which discloses a formwork membe...
