Embodiment 1

[0075] Embodiment 1 is a flat-type demolition-free prefabricated reinforced concrete formwork with intersecting holes inside. The formwork adopts a prefabricated reinforced concrete slab, such as Figure 1a As shown, there is a row of longitudinal through holes 12 and a row of transverse through holes 13 in the plane of the reinforced concrete prefabricated slab 11; Arranged longitudinal steel bars 161 and a plurality of transverse stirrups 162 that connect the steel bars into a whole, such as Figure 1b As shown; it also includes a groove 14 arranged on the side of the reinforced concrete prefabricated slab 11, and an installation ring 15 on one side of the reinforced concrete prefabricated slab; the diameter range of the longitudinal through hole is between 60mm and 300mm ( In general, take the plate thickness minus 60mm. For example, when the plate thickness is 200mm, the diameter of the longitudinal through hole is 140mm). The diameter of the transverse through hole ranges...

Embodiment 2

[0085] Embodiment 2 is a prefabricated reinforced concrete formwork with intersecting holes inside a T-shaped column that does not need to be dismantled. The formwork adopts a T-shaped reinforced concrete prefabricated panel 31, such as Figure 3a As shown, there are vertical through holes 32 in the formwork, and through holes 33 are formed horizontally in the formwork. Grooves 34 are provided on five sides (left, right, front, upper surface, and lower surface) of the T-shaped column formwork. The upper surface is provided with a formwork suspension ring 35 for construction and installation, and a reinforcement cage 36 is arranged in the column formwork, and the reinforcement cage 36 is composed of a plurality of longitudinal reinforcement bars 361 and a plurality of transverse stirrups 362 (T-shaped stirrups), such as Figure 3b shown. The vertical height of the T-shaped column formwork is about 2400mm to 5000mm (generally the height of the building), and the thickness of eac...

Embodiment 3

[0094] Embodiment 3 is a demolition-free prefabricated reinforced concrete coupling beam formwork 71 with intersecting holes inside, the formwork adopts reinforced concrete prefabricated coupling beams, and vertical through holes 72 and horizontal through holes 73 are opened in the coupling beam formwork 71 ,Such as Figure 7c Shown; The groove 74 that is arranged on three sides of coupling beam formwork, as Figure 7a Shown; The reinforcement cage 76 that is arranged in the connecting beam formwork, this reinforcement cage 76 is made up of a plurality of longitudinal reinforcements 761 and a plurality of transverse stirrups 762 that the longitudinal reinforcement 761 is fixedly connected into a whole, as Figure 7b shown. One end of the stirrup 762 is exposed and can be used as an installation ring. The length of the coupling beam formwork is generally about the size of the door and window opening plus 600mm, the height of the coupling beam formwork is the size from the upp...

Abstract

The invention relates to a removal-free prefabricated reinforced concrete template with cross holes inside. The template is a wall template, a floor template, a roof template, a T-shaped template, an L-shaped template, a cross template, a coupling beam template, a beam template or an upright template. A plurality of longitudinal through holes and a plurality of horizontal through holes parallel to the surface are arranged in the template. The plurality of longitudinal through holes and the plurality of horizontal through holes form cross channels. When the removal-free template is prefabricated in factories, 70-80% of stress reinforced concrete is prefabricated in the template, which facilitates industrialization production, transportation and hoisting, and realizes that each layer of house wall template and the floor template are supported once, the concrete is repoured, after the current layer of concrete is poured, the next layer construction is immediately carried out, the construction period of the house is shortened, meanwhile labour is saved, the construction speed is quickened and the house cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of formwork for construction, and in particular relates to a prefabricated cross-holed reinforced concrete hollow ribbed formwork for cast-in-place reinforced concrete structures without dismantling and a manufacturing method. Background technique [0002] At present, most of the cast-in-place reinforced concrete structures use steel formwork or wood boards, bamboo plywood, plastic boards, etc. and steel frame combined formwork systems to pour concrete. During the construction, the steel bars of the components are bound on site in batches, and then the above formwork is spliced ​​and installed on site, and the concrete is poured again. After the concrete is solidified and hardened, the formwork is removed. This construction method has many procedures, and the on-site workload is relatively large, and part of the formwork cannot be reused for a long time, resulting in waste of materials. [0003] In addition...
