Abstract
The utility model relates to a dismantling-free precast reinforced concrete template with crossed holes inside and a manufacturing method. The template adopts a reinforced concrete precast plate, a row of longitudinal through holes and a row of transverse through holes are arranged in the reinforced concrete precast plate to form a crossed passageway, and the longitudinal through holes are parallel with the surface. Most of work for assembling reinforcement in construction site is arranged in a factory for finishing, so the manpower can be saved, the construction speed is increased, and the construction cost of houses is reduced.
Description
Technical field
The utility model belongs to the building form technical field, particularly is used for the prefabricated intersection pore-forming concrete hollow formwork structure design with ribbing of cast-in-situ reinforced concrete structure free removal.
Background technology
At present, cast-in-situ reinforced concrete structure uses steel form or plank, bamboo offset plate, plastic plate etc. and steel framework gang form system pour concrete mostly.The first reinforcing bar of on-the-spot binding structural member in batches during construction, above-mentioned template is installed in splicing at the scene then, and Cast-in-place concrete treats that concrete solidifies the hard back of knot form removable again.This job practices operation is more, and the site work amount can not be reused for a long time than big and segment template, causes waste of material.
In addition, also existingly contain vertically the free removal template of square hole side by side with what plastics or gypsum were made.The pour concrete rear pattern plate is separated into one by one independently square column to concrete, rather than a concrete integral body.Therefore, utilize this template can only build low-rise building, be not suitable for building high-story house, use less at present.
Summary of the invention
The purpose of this utility model is to solve the deficiency that the full cast-in-situ reinforced concrete structure of tradition props up template, form removal complex procedures, provide a kind of free removal in the precast reinforced concrete form of cross bore is arranged.With the job site assembling reinforcement and most of job placement in factory, finish, can save artificial, accelerate speed of application, reduce the house building cost.
The precast reinforced concrete form that cross bore is arranged in a kind of free removal that the utility model proposes, this template adopts the steel bar concrete precast plate, it is characterized in that, has a row vertical perforated holes parallel with the surface in the described steel bar concrete precast plate, with a horizontal row to perforated holes, form cross aisle.
Described steel bar concrete precast plate can be coupling beam template, beam forms or model of the column, and described reinforcing cage can and be fixed into holistic many longitudinal reinforcements with all stirrups by the lateral tie of a plurality of arrangements and form.
Characteristics of the present utility model and beneficial effect:
1 factory process make free removal in when the precast reinforced concrete form of cross bore is arranged, about steel bar stress of 70% to 80% is placed in the prefab form because template is produced in factory, construction quality and plate surface evenness easily guarantee.Utilize prior art can in factory, produce in enormous quantities free removal in the precast reinforced concrete form of cross bore is arranged, form industrialization.
Free removal in the precast reinforced concrete form of cross bore is arranged is the smaller units plate, be convenient to long-distance transport.There is the precast reinforced concrete form of cross bore to can be made into little piecemeal in the free removal, do not need goliath during lifting.
3. can realize that every layer of house wall template and floor template once support finishes, and Cast-in-place concrete is accelerated speed of application then.Significantly reduced the workload of assembling reinforcement at the construction field (site).Can reduce workload and difficulty of construction that the job site template supports.Reduce working strength of workers.The precast reinforced concrete form that cross bore is arranged in the free removal is the part of primary structure member, can save the form removable operation.Because template itself has certain intensity, after the cast of this layer concrete finishes, descend one deck construction at once, can shorten the house building cycle.
