Abstract
The utility model mainly discloses a I -steel type precast reinforced concrete slab, it is that whole of the prefabricated I -steel type that forms is arranged in proper order to roof, web and bottom plate, and its roof, web and bottom plate are whole solid board, and the upside of roof and bottom plate all has the connecting reinforcement who up stretches out. The utility model discloses utility tunnel is assembled to mainly used, and prefabricated back transportation is extremely on -the -spot in batches in the mill, compares with cast in situs, practices thrift the cost greatly. On -the -spot according to actual need is assembled with two cell type precast reinforced concrete slab or is still coordinated the prefabricated flat board that lies in between cell type precast reinforced concrete slab and this I -shaped template to assemble, then carries out one -piece casting superposed layer technology in the bottom surface of top surface and can form the whole synthesis piping lane, shortens construction cycle greatly. Water superposed layer behind the connecting reinforcement messenger of roof and bottom plate upside and guarantee good wholeness ability with the roof and the bottom plate of this prefabricated plate.
Description
Technical field
The utility model relates to a kind of prefabricated reinforced concrete plate, is specifically related to a kind of I-shaped die prefabricated reinforced concrete plate and production mould thereof.
Background technology
Along with the development of urban construction, the construction of underground pipe gallery is about to the climax entering Large scale construction.And the design of underground pipe gallery at present generally adopts steel bar concrete cast-in-place structural, only has the small-bore form of structure just adopting first prefabricated rear assembling of small part, assembling form mainly contains overall point nodal pattern, divides nodal pattern and prefabricated plate three kinds up and down, and the connection between each joint forms rigid unitary respectively by the concrete cast-in-situ band at reinforcing steel structural member pre-buried separately and corresponding reinforcing steel structural member place.The advantage of cast-in-situ reinforced concrete comprehensive pipe gallery structure is that structural safety, water resistance are good, and pipe gallery area is large, but there is the defect of the high and long construction period of cost simultaneously.There is the poor defect of globality in current assembling pipe gallery, thus makes the safety of structure of pipe gallery in practical process and durability there is hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of I-shaped die prefabricated reinforced concrete plate for on-site consolidation underground pipe gallery, is ensureing the prerequisite decline low cost of its globality and safety and is shortening the site operation cycle.
The utility model discloses a kind of I-shaped die prefabricated reinforced concrete plate, it is that top board, web plate and back plate arrange prefabricated I-shaped die single piece successively, its top board, web plate and back plate are unitary solid plate, and all there is the connecting reinforcement up stretched out the upside of top board and base plate.
The upper surface of described top board and base plate all does matsurface process, to make superimposed better effects if.
The invention also discloses a kind of mould of the I-shaped die prefabricated reinforced concrete plate for said structure.
Utility model is mainly used in assembled underground pipe gallery, is transported to scene, compares with cast in situs after factory's batch is prefabricated, greatly cost-saving.On-the-spot assembled with two blocks of grooved prefabricated reinforced concrete plates or also coordinate the prefabricated flat board between grooved prefabricated reinforced concrete plate and this I-shaped template assembled according to actual needs, then carry out monobloc cast overlapping layers technique in the bottom surface of end face and can form whole synthesis piping lane, greatly shorten construction period.The top board and the base plate that water overlapping layers and this precast plate after connecting reinforcement on the upside of top board and base plate makes ensure good overall performance.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of I-shaped die prefabricated reinforced concrete plate, it is that top board 1, web 2 and base plate 3 arrange prefabricated I-shaped die single piece successively, its top board 1, web 2 and base plate 3 are unitary solid plate, and all there is the connecting reinforcement 4 up stretched out the upside of top board 1 and base plate 3.
The top board 1 and the base plate 3 that water overlapping layers and this precast plate after connecting reinforcement 4 on the upside of top board 1 and base plate 3 makes ensure good overall performance.
The utility model is mainly used in assembled underground pipe gallery, is transported to scene, compares with cast in situs after factory's batch is prefabricated, greatly cost-saving.On-the-spot assembled with two blocks of grooved prefabricated reinforced concrete plates or also coordinate the prefabricated flat board between grooved prefabricated reinforced concrete plate and this I-shaped template assembled according to actual needs, then carry out monobloc cast overlapping layers technique in the bottom surface of end face and can form whole synthesis piping lane, greatly shorten construction period.The top board and the base plate that water overlapping layers and this precast plate after connecting reinforcement on the upside of top board and base plate makes ensure good overall performance.
The invention also discloses a kind of mould of the I-shaped die prefabricated reinforced concrete plate for said structure, I shape prefabricated reinforced concrete plate is produced as vertical production, mould comprises exterior sheathing, inner formword and edge sealing mould, exterior sheathing is designed to drum according to i iron peripheral shape, can be spliced by two pieces of large steel moulding plates by splitting, connection between large form with large form is for welding or bolt connection, simultaneously also add with brace reinforcement of weld of putting more energy between the large form of each perpendicular type junction and large form, large form construction itself is dull and stereotyped and vertical transverse stiffener forms, stiffening rib material is box section, stiffening rib was fixedly connected with by full weld or bolt with dull and stereotyped connection, the connecting reinforcement that I-shaped die prefabricated reinforced concrete plate up stretches out all need to punch pre-buried producing at exterior sheathing, inner formword is also drum according to the design of i iron peripheral shape, be that six pieces of large forms are spliced, connection between large form with large form is for welding or bolt connection, also add between the template of each perpendicular type junction and template with brace reinforcement of weld of putting more energy into, large form construction itself is that plain plate and vertical transverse stiffener form, and stiffening rib was fixedly connected with by full weld or bolt with dull and stereotyped connection, be connected to form entirety by two pieces of edge sealing moulds between exterior sheathing and inner formword, the connected mode of exterior sheathing or inner formword and edge sealing mould is for weld or bolt is connected.
Claims (3)
1. an I-shaped die prefabricated reinforced concrete plate, it is characterized in that: it is that top board, web plate and back plate arrange prefabricated I-shaped die single piece successively, its top board, web plate and back plate are unitary solid plate, and all there is the connecting reinforcement up stretched out the upside of top board and base plate.
