Description
Technical field
The utility model relates to a kind of built-in type rigid polyvinyl chloride pipe collar that is used for concrete placement, relates in particular to the structure of this pipe collar.
Background technique
By Figure 1A, Figure 1B, Fig. 2 A, Fig. 2 B, Fig. 3 as seen: respectively there is a stiffening rib 1 two bellmouth oral areas of rigid polyvinyl chloride pipe collar outer ring in the prior art, and bellmouth root inner ring has a positioning bar 2.Pour into a mould when pre-buried when pipe collar is used for concrete B, generally pipe collar is fixed on the template, but or pipe collar is fixed on bearing with rope 4 with stiffening rib 1 outer ring of iron nail 3 at the pipe collar bellmouth oral area that contacts with template A.Pre-buried when being used for concrete placement, because that pipe collar is the smooth circle in outer ring is straight-through, under the effect of external force, don't work iron nail 3 or rope 4 all are difficult to the pipe collar fixed-site dead, are offset or inclination through regular meeting's occurrence positions, have influenced and being connected of tubing 5.
Be to reduce difficulty of construction, not contraposition up and down when preventing to be connected because of leaking of causing of position deflection or inclination or with tubing is necessary the structure of the built-in type rigid polyvinyl chloride pipe collar that is used for concrete placement is transformed.
Summary of the invention
The utility model technical issues that need to address have provided a kind of built-in type rigid polyvinyl chloride pipe collar, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the last bellmouth that injection moulding fuses is straight-through and following bellmouth is straight-through; There is a stiffening rib the described straight-through root outer ring of bellmouth of going up; The bottom of described stiffening rib links to each other with the straight-through root outer ring of bellmouth on this, and the straight-through root outer ring of bellmouth forms straight-through first recessed groove of root direction of bellmouth on this with being somebody's turn to do upward on the top of stiffening rib; Described bellmouth down is straight-through to be made up of inner structure layer and external structure layer; The root of inner structure layer and external structure layer links to each other with the straight-through root of last bellmouth; The oral area of external structure layer has a fixed plate, and the fixing column that links to each other with this external structure layer outer ring is arranged on the fixed plate; Described fixing column is no less than 2; The circular hole that passes fixed plate and fixing column is arranged on each fixing column, and the external structure floor height forms one to the straight-through second recessed groove of root direction of this time bellmouth in the inner structure layer between the inside and outside construction layer.
Compared with prior art, the beneficial effects of the utility model are: owing at the bellmouth oral area that inside and outside construction layer is arranged the fixing column that fuses with external structure layer outer ring and fixed plate is arranged, pre-buried when being used for concrete placement, the circular hole that only needs to pass fixing column with iron nail just can be fixed on pipe collar on the template, has improved speed of application; The inside and outside construction layer of this bellmouth can clamp tubing in addition, has reduced difficulty of construction; On the other hand, because the stiffening rib and the groove of another bellmouth root outer ring can increase and concrete adhesion, can prevent that again sealing is along this bellmouth outer ring and concrete gap leakage.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 4: the utility model comprises: last bellmouth that injection moulding fuses straight-through 10 and following bellmouth straight-through 20; There is a stiffening rib 11 the described straight-through 10 root outer rings of bellmouth of going up; The bottom of described stiffening rib 11 links to each other with the straight-through 10 root outer rings of bellmouth on this, and the straight-through 10 root outer rings of bellmouth form straight-through first recessed groove 12 of 10 root directions of bellmouth on this with being somebody's turn to do upward on the top of stiffening rib 11; Described down bellmouth straight-through 20 is made up of inner structure layer 21 and external structure layer 22; The root of inner structure layer 21 and external structure layer 22 links to each other with straight-through 10 roots of last bellmouth; The oral area of external structure layer 22 has a fixed plate 221, and the fixing column 222 that links to each other with these external structure layer 22 outer rings is arranged on the fixed plate 221; Described fixing column 222 is no less than 2; The circular hole 223 that passes fixed plate 221 and fixing column 222 is arranged on each fixing column 222, and external structure layer 22 is higher than inner structure layer 21, forms one between the inside and outside construction layer to the straight-through second recessed groove 224 of 20 root directions of this time bellmouth;
Described stiffening rib 11 is that a bottom width is 3-10mm, upward the wide 1-8mm of being, height are the round column structure of 1-6mm;
Described first groove 12 is the wide 0.5-5mm of being, is the groove of 0.3-5mm deeply;
Described fixed plate 221 is the wide 5-30mm of being, height is the circle structure of 1-8mm;
