Description
Technical field
The utility model relates to municipal works field, in particular to a kind of precast concrete roof-drain module.
Background technique
During road construction, inlet for stom water construction can be selected to finish in base layer construction, be carried out before asphalt paving.Have in the past
Two kinds of inlet for stom water construction technologies, i.e. brick type inlet for stom water and precast concrete assembled inlet for stom water.Brick type inlet for stom water construction speed
Degree is slow, influences overall progress；Sand finish technical difficulty is big, easily causes impression quality unqualified, and mortar easily cause fugitive dust and
Ground pollution.Breakage is easily caused in precast concrete assembled inlet for stom water transportational process, and on-site consolidation difficulty is big, piece is more
Easily cause leak.
Utility model content
The utility model in order to make up for the deficiencies of the prior art, provides a kind of precast concrete roof-drain module.
The utility model is achieved by the following technical solution:
A kind of precast concrete roof-drain module, it is characterised in that: including body die and bottom plate mold；The main body mould
Tool includes external mold and the inner membrance inside external mold, and the external mold is case shape, is connected by side template and bottom surface template by screw
Connect composition；The inner membrance includes two single grate internal models placed side by side, is placed with lintel internal model between two single grate internal models, wherein
Water inlet internal model is equipped between one single grate internal model and the side template of external mold；The list grate internal model by two the first right angle forms,
Two the second right angle forms and two straight flange template splicings form, and splicing angle is 60 °/120 °；Straight flange template upper surface
To be trapezoidal, trapezoidal base angle is 60 °, and two straight flange templates are located on the opposite both sides of single grate internal model, and two straight flange templates
It is symmetrical along single grate inner mold center line.
Wherein, the lintel internal model height is the 1/3-2/3 of single grate internal model height.
Wherein, single grate internal model height is suitable with the side template height of external mold.
Wherein, the bottom plate mold is case shape, and by bottom die, bottom plate side form is made up of screw.
Wherein, the bottom die is equipped with hanging ring preformed hole.
The utility model bottom plate mold penetration concrete forms the bottom plate of precast concrete roof drain after solidifying；Body die
Penetration concrete forms the main body of precast concrete roof drain after solidifying；The main body of precast concrete roof drain and floor combination at
Complete precast concrete roof drain.
When body die penetration concrete, concrete is located at external mold and inner membrance is formed by cavity, when concrete is solid
After change, external mold and inner membrance are successively removed, cavity is wherein formed at inner membrance, forms water inlet at water inlet internal model；Single grate internal model is simultaneously
It is non-integral to form, but by by two the first right angle forms, made of two the second right angle forms and two straight flange template splicings
Rectangular body, the purpose is in demoulding, avoid because concrete expansion squeeze lead to template slight deformation due to make demoulding during
Concrete is damaged.
The beneficial effects of the utility model are: the utility model can concentrate batch making inlet for stom water with multiple groups mold, both solved
Brick type inlet for stom water speed of having determined also solves the problems, such as that the assembling of assembled roof drain is difficult slowly.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is that main mould faces positive elevational schematic view；
Fig. 2 is that main mould faces side elevation schematic diagram；
Fig. 3 is main mould overlooking structure diagram；
Fig. 4 be bottom plate mold bow structure regard schematic diagram；
Fig. 5 is that bottom plate mold faces positive elevational schematic view；
Fig. 6 is precast concrete roof drain finished product.
In figure, 1 body die, 2 bottom plate molds, 3 external molds, 4 inner membrances, 5 single grate internal models, 6 lintel internal models, 7 mouth of a river internal models, 8
First right angle form, 9 second right angle forms, 10 straight flange templates, 11 bottom dies, 12 bottom plate side forms, 13 hanging ring preformed holes.
Specific embodiment
Attached drawing is a kind of specific embodiment of the utility model.The embodiment includes body die 1 and bottom plate mold 2；Institute
Stating body die 1 includes external mold 3 and the inner membrance 4 inside external mold 3, and the external mold 3 is case shape, by side template and bottom surface mould
Plate is connected by screw to composition；The inner membrance 4 includes two single grate internal models 5 placed side by side, is placed between two single grate internal models 5
There is lintel internal model 6, is equipped with water inlet internal model 7 between one of list grate internal model 5 and the side template of external mold 3；The list grate internal model 5
By two the first right angle forms 8, two the second right angle forms 9 and two straight flange templates 10 are spliced, splicing angle be 60 °/
120°；10 upper surface of straight flange template be it is trapezoidal, trapezoidal base angle be 60 °, two straight flange templates 10 are located at single grate internal model 5
