Abstract

The invention relates to a U-shaped precast concrete shell with inner ribs, which is mainly used for manufacturing a reinforced concrete beam. A hoping and a protective layer of the reinforced concrete beam are manufactured into a precast U-shaped shell which is not only used as a construction plank of the reinforced concrete beam, but also used as part of the structure to participate the joint work so as to be beneficial to saving a great amount of construction templates and workload thereof, improving the construction efficiency, lightening the labor force, realizing the cross operation, decreasing the construction cost, ensuring the building quality, saving resources and energy sources, protecting the environment and promoting the industrialized building development. The manufacture method of the U-shaped precast concrete shell adopts a rapid molding method, not only has simple manufacture and thin wall, but also can ensure the precast shell can be reliably bond and jointly work with post-cast core concrete by the inner ribs of the shell. In addition, the manufacture method of the U-shaped precast concrete shell can satisfy the thin-wall requirements and ensures that the protective layer thickness of the reinforced concrete beam main rib is the protective layer thickness of standard specifications.

Description

Band internal-rib U-shaped precast concrete shell and making worker method thereof
Technical field
The present invention is for band internal-rib U-shaped precast concrete shell and make worker's method, adopts this U-shaped shell can make RC beam (also claiming novel assembling RC beam).
Background technology
At present, the general job practices that adopts traditional integral cast-in-situ of steel concrete (RC) beam and structure, this job practices is passed through formwork, configuration and assembling reinforcement, concreting, maintenance, reinforced concrete building is built in form removal, this worker's method can guarantee conscientiously that reinforced concrete structure and member have more superior structural performance and also accepted by the engineering staff, but, a large amount of concrete all is cast in situs when adopting traditional construction, not only exist the field operation amount big, duration is longer, the labor strength height, big to ambient influnence (as noise, airborne dust, water pollutes, building waste is many and quality is affected by environment big) etc. defective, and be difficult to guarantee workmanship.So development green building, promotion green construction, realization industrialization of construction industry are the important measures of building energy conservation.In addition; compare with cast-in-situ construction method; adopt U-shaped precast concrete shell making RC beam and structure to help green construction; because fabricated construction more can meet requirements such as the saving land of green construction, energy-conservation, material-saving, water saving and environmental protection; reduction is to the negative effect of environment; comprise the reduction noise, prevent airborne dust, reduce environment pollution, clean transportation, reduce the resource and the energy such as place interference, conserve water, electricity, material, follow principle of sustainable development.Assembling RC beam and structure reduce building waste (account for municipal refuse total amount 30%~40%) largely, as steel scrap muscle, scrap iron silk, useless bamboo timber, discarded concrete etc.
Summary of the invention
The purpose of this invention is to provide the band internal-rib U-shaped precast concrete shell and the phase making worker method of making assembling RC beam.
This U-shaped shell adopts the prefabricated shell of manufactured by common concrete, and concrete also can adopt the bigger high-flowing concrete of slump certainly, and the effect of building is better, makes more convenient.U-shaped concrete casing inboard has along U-shaped outer cover height direction and to the internal-rib of inner process, and internal-rib can be made triangularity, trapezoidal, semicircle etc.The stirrup of reinforced concrete beam is cast in the U-shaped shell, and stirrup guarantees that so the slotting main muscle in back is the protective layer thickness of RC beam to the distance of U-shaped concrete casing external surface in the rib that two limbs are dashed forward in the U-shaped shell.Thereby prefabricated U-shaped shell is light weight not only, and easily lifting, and be applicable to the making of RC beam guarantees that stirrup, main reinforce position and the stirrup of common RC beam, main muscle are consistent.
The making worker method of band internal-rib U-shaped precast concrete shell comprises: external mold, support, internal mold, fastener, wherein internal mold is made up of baffle plate, plate 1, plate 2 and internal mold erection bolt with ribbing.Worker's method one: before the concreting, external mold is installed earlier, cast U-shaped outer casing bottom concrete; Then, assembling internal mold, location stirrup hang in the internal mold internal mold that stirrup is housed and the location; Build the concrete of U-shaped side plate at last, concrete soil solidifies back form removal maintenance.Worker's method two: external mold is installed earlier; Then, assembling internal mold, location stirrup hang in the internal mold internal mold that stirrup is housed and the location; Build the concrete of U-shaped outer casing bottom, side plate at last, concrete soil solidifies back form removal maintenance, and this is that concrete flowability suitably increases, and guarantees that outer casing bottom concreting is closely knit.
The advantage of band internal-rib U-shaped precast concrete shell and making worker method thereof is:
(1) band internal-rib U-shaped shell can be used as the construction formwork of reinforced concrete beam, significantly reduces the use amount of template, helps saving resources such as timber;
(2) the main muscle according to design RC beam is cast in the prefabricated shell of band internal-rib U-shaped, saves the workload of a large amount of assembling reinforcements;
(3) band internal-rib U-shaped outer cover quality is lighter, and is lower to the requirement of hanging device, and the existing hanging device of job site can satisfy to be lifted with fully to be asked;
(4) band internal-rib U-shaped shell band internal-rib, this is an original creation part of the present invention, can fine assurance core concrete and the reliable bonding and the co-operation of prefabricated shell;
(5) internal mold of the manufacture craft of band internal-rib U-shaped prefabricated shell is a characteristic of the present invention, and the baffle plate of the trapezoidal cross-section internal-rib that both had been shaped also plays the location stirrup simultaneously, guarantees that the wall thickness of thin-walled U-shaped shell reaches the protective layer thickness of RC member;
(6) the form removal method of internal mold is an innovative point of the present invention, will extract out after the dislocation of two internal molds, the interior receipts, guarantees the realization of " shaping of loosing core fast " worker's method.
