Through improving to side the thickness of the wall, especially through the continuous incremental manner setting of multistage side the thickness of the wall, guaranteed when effectively lightening diaphragm capsule self dead weight that the lateral wall that is in coincide face department has sufficient coincide thickness, guaranteed the circumstances that the coincide in -process can not diaphragm capsule that take place misplaces because coincide face department lateral wall thickness is narrower.

Description

Built-in pore-forming combination gypsum core

Technical field

This utility model relates to the built-in pore-creating core of cast-in-place concrete hollow building roof, particularly to built-in pore-forming combination gypsum core.

Background technology

In cast-in-place concrete hollow building roof in the prior art, a large amount of employings comprise or do not comprise the industrial wastes such as the Gypsum Fibrosum of reinforcing glass fiber becomes the permanent built-in pore-creating core of filling by Mold Making.It is such as CN202227554U at Authorization Notice No., in entitled " pin type plaster mould shell and concrete combined dense rib flat slab " Chinese invention patent description, take the closed hollow " gypsum evacuated mould shell " that " Shear connection pin " connects as permanent built-in pore-creating core.It is CN201195901Y at Authorization Notice No., in entitled " a kind of built-in armored concrete space floor construction " Chinese utility model patent description, the hollow core of the closing that the opening surface docking combination taking about two the Gypsum Fibrosum cavitys arranged to fill diaphragm capsule is formed by stacking.But the thickness of diaphragm capsule is single thickness in above-mentioned two schemes, if increasing the thickness of diaphragm capsule, certainly will increase estimating one's own ability of diaphragm capsule, mould box structure is unreasonable.If reducing the thickness of diaphragm capsule, certainly will cause at the overlapping of sidewall narrow, being susceptible to the defect such as superposed surfaces dislocation or diaphragm capsule breakage and diaphragm capsule cannot be made to form the situation closing cavity, and then during practice of construction, affecting the hollow rate of superstructure.

Therefore those skilled in the art be devoted to develop more conduct oneself with dignity relatively light, structural strength is the most reasonable and overlaps more convenient and stable Gypsum built-in core, can effectively prevent the dislocation displacement between the combination diaphragm capsule of Gypsum built-in core and combination diaphragm capsule damaged in transport and work progress, so reduce therefore and the Gypsum built-in core that causes is damaged or affect the defect odds such as superstructure hollow rate.

Summary of the invention

Drawbacks described above in view of prior art, technical problem to be solved in the utility model is that relatively gently and structure is the most reasonable, it is more convenient to overlap by providing one deadweight, effectively prevent combination gypsum core in work progress damaged or dislocation displacement, prevent the uneven situation of superstructure hollow rate further and occur.

For achieving the above object, built-in pore-forming combination gypsum core is made up of two diaphragm capsules including setting symmetrical above and below, described diaphragm capsule is integrally molded so as one end by base plate and sidewall connected vertically with base plate and closes the diaphragm capsule of other end opening, two diaphragm capsules are superimposed as totally-enclosed cavity up and down by the superposed surfaces of sidewall, vertical section is the most continuously coupled constitutes by the first vertical section, indent arc section, evagination arc section and second for described sidewall, and the tranverse sectional thickness of described sidewall is incremented by sidewall superposed surfaces successively from plate inner wall face.By improving for the composition structure of sidewall and thickness, the continuous incremental manner of thickness especially by multistage sidewall is arranged, while effectively alleviating diaphragm capsule self deadweight and ensureing mould box structure intensity, ensure that being in the sidewall at superposed surfaces has enough overlapping thickness, it is ensured that the situation of the diaphragm capsule dislocation that will not occur in lamination process because sidewall thickness at superposed surfaces is narrower.

Accompanying drawing explanation

Fig. 1 is the two diaphragm capsules overlapping figure up and down of the combination gypsum core of this utility model embodiment.

Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

As shown in Figure 1 in embodiment, built-in pore-forming composite core formwork is by upper, lower two symmetrical diaphragm capsules (1) composition, diaphragm capsule is made up of for overall sidewall (3) square floor (2) and being connected with base plate, base plate and sidewall are to be fabricated to one end by mould one-shot forming to close the diaphragm capsule of other end opening, wherein base plate is blind end, the other end is opening, after two diaphragm capsules are superimposed with each other by the superposed surfaces (35) on sidewall, form totally enclosed cavity (4), above-mentioned have the diaphragm capsule closing cavity after overlapping is combined as core, it is placed in cast-in-place concrete floor and i.e. forms cast-in-place hollow space.The sidewall of diaphragm capsule is by the first vertical section (31), indent arc section (32), evagination arc section (33) and the second the most continuously coupled composition of vertical section (34), the tranverse sectional thickness of sidewall is incremented by sidewall superposed surfaces successively from plate inner wall face (21), wherein one end of the first vertical section is connected for intersecting vertically with base plate, one end of indent arc section is connected with each other with the other end of the first vertical section, one end of evagination arc section is connected with each other with the indent arc section other end, one end of second vertical section is connected with the evagination arc section other end, the end of the other end is superposed surfaces, i.e. second vertical section is formed parallel in the outside of the first vertical section with the first vertical section, indent arc section forms serpentine shape cross section after being connected with evagination arc section, continuous tangent connection can be formed between two sections before and after aforesaid sidewall.The thickness of the first vertical section is more than indent arc section, the thickness of indent arc section is more than evagination arc section thickness, the thickness of indent arc section is more than the thickness of evagination arc section, and the thickness of evagination arc section is more than the thickness of the second vertical section, and above-mentioned incremental thickness could be arranged to linear increment.

The first vertical section, indent arc section, outer concave arc section and the composition structure of the second vertical section due to sidewall, " I " cast-in-place cross section can also be formed in relevant position in the cast-in-situ floor of side-wall outer side, it is beneficial to again whole floor structure stress, can also effectively promote composite core formwork and then prevent composite core formwork from coming off, can prevent composite core formwork from floating in work progress again.And the different-thickness being incremented by continuously of sidewall is arranged and the transition connected mode of different circular arc, the overall structure making core is the most reasonable, that on the one hand can reduce core uses material, the effective deadweight reducing core, the opposing party can guarantee that again the superposed surfaces of sidewall has enough overlapping thickness, after preventing from causing superposed surfaces thickness to reduce because entirety reduces sidewall thickness, and then generation overlaps the situation misplacing or causing core damaged and occurs.

In addition to the diaphragm capsule in above-described embodiment is square floor, the abnormity such as diaphragm capsule base plate can also be provided in round according to construction needs, polygon or irregular polygon, can also transform size as required between each section of corresponding sidewall.
