Abstract
The invention belongs to the field of building materials and a designing and manufacturing technology of a BOAO hollow floor bar-mat reinforcement sandwiching a light mandrel. The simple-structure mandrel is wrapped by a bar-mat reinforcement sheet to be manufactured into a whole. Side wall reinforcing steel bars serve as floor concrete shearing resistance stress, surface layer and bottom layer reinforcing steel bars are designed to be anti-crack reinforcing steel bars and ribbed beam stirrups so as to facilitate construction of ribbed beam reinforcing steel bar, an inner mold can be effectively positioned, and a protection layer is reserved. The mandrel is a light (hollow) component. The mandrel is light and is not prone to be damaged. Advantages of light qualities, low manufacture costs, environmental friendly materials, and ensured qualities are achieved, by means of the BOAO hollow floor bar-mat reinforcement sandwiching the light mandrel, construction speeds are increased, durability is greatly improved, and a wide development space is achieved.
Description
Technical field:
The present invention relates to buildings in general structure field, be mainly concerned with a kind of manufacturing technology of BOAO cassette ceiling reinforcing bar network folder Lightweight core mould.
Background technology:
Since reforming and opening up to the outside world 30 years, the infrastructure of China has obtained develop rapidly, and builing industry has become mainstay of the national economy industry.Whole nation forest resourceies are deficient, are difficult to the wooden industry structure of development, and for protecting farmland, clay brick masonry structure is also restricted.Steel work is promoted, but cost, the problems such as fire prevention and durability make it be difficult to popularize, concrete structure is the principal mode of Building Trade in China, and at quite a long time concrete structure or the principal mode of Building Trade in China, because concrete structure consumes the energy and resource in a large number, the steel that builing industry is brought, the consumption of cement and the builing industry energy and to affect the problem of sustainable development more and more serious.Steel, cement is all to consume the serious product of the energy, and along with wideling popularize of concrete structure, the demand of steel also can go up greatly, and Sha Yuan is day by day exhausted, and unordered exploitation is serious by environmental destruction.Face the form of above sternness, the development model of builing industry must be made huge adjustment, improves the utilization rate of structural meterials, development economy type structure is inevitable direction, and the form of optimizing structure, promotes from heavy and light, energy-conserving and environment-protective, the hollow floor that comprehensive cost is low has become one of important directions.In recent years, to imbed a core, the cast-in-place concrete hollow floor slab that casing or other lightweight filler are means is developed rapidly, in hollow building cover field, also emerges numerous innovative technologies.Patented technology " thin wall cylinder filling type cast-in-situ concrete tubular, hollow floor " (ZL99232922.1) discloses a kind of thin wall cylinder and has applied in cast-in-situ concrete, " a kind of steel bar reinforced floor with tubular holes " (ZL01140463.9), " a kind of steel bar reinforced floor with tubular holes " technology (ZL01140463.9) and in " a kind of cast-in-place concrete cored " (application number 200510067584.5) continues the application in cassette ceiling to tubulose filler and innovates, cast-in-place concrete hollow floor slab has from heavy and light, antihunt action is good, insulation, heat insulation, the features such as sound insulation.Also can reduce concrete consumption, alleviate the effect of earthquake.Further perfect along with the research of internal force analysis and cross section, cassette ceiling manufacture craft has great practical value.In order to solve traditional hollowcore slab bottom without girder and the low shortcoming of weight bearing power, tubulose filler should be changed into square filler, and square filler can make the load force direction of transfer average mark of floor be placed in surrounding, by certain rule, place after embedded inner mold, through poured in place concrete, in floor, form the superstructure of cavity, " internal mold " is the lightweight casing core that embedding cast-in-place concrete building roof does not take out in order to form hollow, concrete hollow building roof is in order to form, participation structure is not stressed for it, after concrete formation, the internal mold industry mission of just finishing the work.For avoiding occurring shear failure, also to give full play to hollowcore slab along the good advantage of pipe direction shear behavior.For achieving the above object, the technical solution used in the present invention is: core is wrapped up in reinforced mesh outward, is made of one.Sidewall reinforcing bar is stressed as floorslab concrete shearing resistance, and surface layer and bottom layer of the reinforcing steel are cracking resistance reinforcing bar and the design of girt strip hoop gold, facilitate girt strip reinforcement construction, and can, effectively by fixed internal formwork, leave topping.Core is lightweight (hollow) member.This structure light weight and be not easy breakage.Also have quality light, cost is low, material environment friendly, and the advantages such as the easy assurance of quality, adopt this section structure speed of application to improve, and have greatly improved durability, have wide development space.
Summary of the invention:
BOAO cassette ceiling reinforcing bar network folder light core film, is mainly concerned with a kind of simple in structure, and core is wrapped up in reinforced mesh outward, is made of one.(figure mono-BOAO cast-in-place concrete hollow building roof steel mesh reinforcement sandwich lightweight inner membrance sectional drawing) sidewall reinforcing bar is stressed as floorslab concrete shearing resistance; surface layer and bottom layer of the reinforcing steel are cracking resistance reinforcing bar and the design of girt strip hoop gold; facilitate girt strip reinforcement construction, and can, effectively by fixed internal formwork, leave topping.(figure bis-BOAO cast-in-place concrete hollow building roof steel mesh reinforcement sandwich lightweight inner membrance top views) core is lightweight (hollow) member.This structure light weight and be not easy breakage.

Specific embodiment:
The present invention is BOAO cassette ceiling reinforcing bar network folder light core film, a most preferred embodiment:
(1) lay floor, and in template, to take " well " word beam be girder, the region surrounding at " well " beam is divided and is longitudinally arranged that core wraps up in reinforced mesh outward, is made of one.
(2) the plate face shear reinforcement of the longitudinal reinforcement of colligation core part surrounding and transverse reinforcement.
(3) in the hole, side of " well " font in the besieged city of concrete steel muscle in length and breadth, place modular prefabricated.
(4) place new core part in well, with the iron wire colligation core part of installing in advance number.
(5) by certain rule, place after embedded inner mold, through poured in place concrete, in floor, form the superstructure of cavity, put into lightweight casing core, after concrete formation, the internal mold mission of also just finishing the work.
With a kind of simple in structure, sidewall reinforcing bar is stressed as floorslab concrete shearing resistance, and surface layer and bottom layer of the reinforcing steel are cracking resistance reinforcing bar and the design of girt strip hoop gold, facilitate girt strip reinforcement construction, and can, effectively by fixed internal formwork, leave topping.Core is lightweight (hollow) member.This structure light weight and be not easy breakage.Also have quality light, cost is low, material environment friendly, and the advantages such as the easy assurance of quality, adopt this section structure speed of application to improve, and have greatly improved durability, have wide development space.
