Abstract
The invention discloses a cast-in-situ sprayed concrete hidden bearing platform and hidden ground beam molding bed. The cast-in-situ sprayed concrete hidden bearing platform and hidden ground beam molding bed comprises a base groove which is dug in a predetermined hidden bearing platform and hidden ground beam position, wherein an iron wire net or an iron wire mesh is welded to the position of a concrete bottom plate cushion layer along the wall surface of the base groove; a plurality of L-shaped anchor nails are arranged in a soil body of the wall surface of the base groove at intervals and are connected with the iron wire net or the iron wire mesh through a tie iron wire; a concrete layer covers the wall surface of the base groove; the iron wire net or the iron wire mesh and the L-shaped anchor nails are arranged in the concrete layer. A concrete hidden bearing platform and a hidden ground beam are cast with the molding bed, so that the operation is convenient, the speed is high, the applicability is high, a support template is not needed, the subsequent process can be constructed within 24 hours after concrete is completely sprayed, the intermission time of the processes is short, and a waterproof layer can be directly constructed without plastering. The cast-in-situ sprayed concrete hidden bearing platform and hidden ground beam molding bed is applicable to template construction of cast-in-situ reinforced concrete hidden bearing platforms and hidden ground beams.
Description
Technical field
The present invention relates to a kind of dark cushion cap of cast-in-place gunite concrete and secretly beam loose tool, belong to cast in situ concrete foundation and ground
Beam forms construction technology.
Background technology
The template of the dark cushion cap of existing cast-in-place concrete and secretly beam, because concreting rear pattern plate is with cushion cap and grade beam one
Play embedment underground it is impossible to remove, template system can not affect the bearing capacity of ground simultaneously, how using building the brick loose tool plastered by laying bricks or stones,
After develop precoated plate assembly loose tool, there is inefficiency in above-mentioned 2 kinds of methods, corner and special-shaped socket form moulding difficulty effect are poor
The shortcomings of, especially when needing to carry out waterproof coiled material construction on loose tool in addition it is also necessary to carry out special handling.
Learn the patent of mandate by retrieval：
1st, the Chinese patent " system of a kind of building pile foundation cushion cap and grade beam loose tool of Publication No. CN101725247
Make ", using according to pile foundation pile cap shape, physical dimension and quantity, it is prefabricated into concrete polygon cylinder loose tool in advance, grade beam is then
Grooved is prefabricated into according to sectional dimension concrete moulding bed.
2nd, the Chinese patent " a kind of foundation formss of application GRC cement plate " of Publication No. CN 203229962 U, adopts
GRC cement plate is template plate body, and template plate body is enclosed in plan and pours around basis, stands on and be connected to blinding layer upper surface,
It is embedded with timber wedge of top tape steel nail, embedment steel nail in template top interval is drawn with the steel nail at the sub- top of timber wedge in the earthwork of basic surrounding
Steel wire rope is fixed, and has internal stay between two pieces of relative GRC templates, and the space between template and ground adopts dirt to fill.
3rd, the Chinese patent " concrete-formwork-precast foundation construction method " of Publication No. CN 102505709 A, it does
Method：Excavation pit makes concrete foundation template and according to the shape of institute's foundation ditch, concrete foundation template is assembled in base
In hole, form the backfilling of earthwork outside the integral mold plate foundation ditch on basis and tamp.Its way of Concrete Beam Reinforced：Excavate base
Hole makes concrete foundation template and is assembled in foundation ditch concrete foundation template according to the shape of institute's foundation ditch, composition
Basis integral mold plate foundation ditch outside backfilling of earthwork and tamp.
4th, the Chinese patent " concrete-formwork-precast foundation construction method " of publication number CN 202214982 U, its way：
Template includes glass magnesium board, tension iron wire, timber and supports flitch；Main template body is two blocks of glass magnesium criterion plates and one piece of glass magnesium base plate
The groove-like structure of composition, tension iron wire is all arranged in the outside of two pieces of glass magnesium lateral, and tension iron wire one end penetrates Baume side plate through ferrum
Piece is fixed on inside glass magnesium lateral, and the other end is strained and fixed with the described timber of embedment earth's surface；It is fixedly connected below Baume base plate
There is base plate timber；Laterally homogeneous facet supporting square timber in described two pieces of glass magnesium lateral.
The template of above-mentioned four top patents is prefab-form, there is problems with：1st, prefab-form installation procedure is many；2nd, pre-
There is gap it is impossible to ensure the bearing capacity of ground between pallet and ground.
5th, the Chinese patent being disclosed as CN 102535846 A discloses " building construction integrated poured one-shot forming construction work
Skill ", this patent way is：Require according to construction drawing, formulate construction requirement and the planning book of integrated poured one-shaping technique,
Prefab-form module, the ground beam template of the banded good reinforced frame of supporting and then pour into a mould concrete, solidification reaches after intensity at it
Carry out formwork module supporting after upper laying, assembling reinforcement and bar-mat reinforcement, concrete embedded by construction technical requirement laying, configuration
Part, power supply facilities illuminating line, water-feeding ＆ drainaging pipeline, ventilation passage, heating facility etc., then carry out one-piece casting.This is special
Sharp template is cast-in-place module, but because the formwork module of this patent needs scene to tie up reinforcing bar, formwork supporting plate, pouring concrete, exists：Mould
Plate needs formwork in itself；Operation is many, long in time limit；The shortcoming of concrete set time length.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide that a kind of speed is fast, easy to operate, do not affect ground
Bearing capacity, do not need formwork supporting plate, site operation it is adaptable to various sizes, the dark cushion cap of cast-in-place gunite concrete of shape and secretly
Beam loose tool.
The dark cushion cap of cast-in-place gunite concrete of the present invention and secretly beam loose tool, it includes excavating in predetermined dark cushion cap and dark
The foundation trench of grade beam position, is welded with wire gauze or reinforced mesh up to concrete floor bed course position along foundation trench wall, in foundation trench
In the soil body of wall, interval has set many L-shaped holdfasts, and many described L-shaped holdfasts adopt drawknot iron wire and wire gauze or reinforcing bar
Mesh sheet connects, and is coated with concrete layer, described wire gauze or reinforced mesh and many L-shaped holdfast settings on foundation trench wall
In concrete layer.
Using the dark cushion cap of loose tool casting concrete of the present invention and secretly beam, easy to operate, speed is fast, strong applicability, be not required to
Want the complete 24h of formwork supporting plate, construction of shotcrete can carry out next procedure construction, the operation intermittent time is short it is not necessary to plaster can
Directly carry out construction of waterproof layer.It is applied to the template construction of the dark cushion cap of cast-in-situ steel reinforced concrete and secretly beam.
