Detailed description of the invention
The mould of the prefabricated concrete hollow slab of employing rubber tube pore-forming of the present invention includes rectangular frame, rectangle frame
Frame includes the first side plate 1 and the second side plate 2 being parallel to each other, respectively by being parallel to each other between the first side plate 1 and the second side plate 2
The 3rd side plate 3 be connected with the 4th side plate 4, the first side plate 1 is offered at least one first through hole 5, with each on the second side plate 2
First through hole 5 correspondence position offers the second through hole 6, arranges the first riser 7, with each first on the first riser 7 outside the first side plate 1
Through hole 5 correspondence position arranges the first mounting seat 8, and each first mounting seat 8 is all offered through hole 9, each through hole 9 all with breather line 10
Connecting, breather line 10 is closed conduct, and breather line 10 one end arranges air inlet/outlet 11, installs and seal valve at air inlet/outlet 11
Door 12, arranges the second riser 16, the second riser 16 arranges the second peace with each second through hole 6 correspondence position outside the second side plate 2
Dress seat 13, installs inflated rubber pipe 14 between the first mounting seat 8 and the second mounting seat 13, inflated rubber pipe 14 two ends are socketed respectively
On the outer wall of the first mounting seat 8 and the second mounting seat 13, inflated rubber pipe 14 passes from the first through hole 5 and the second through hole 6,
Arranging bed die 15 bottom rectangular frame, the first riser 7 and the second riser 16 are connected with rectangular frame or bed die 15.Make concrete
During cored slab, being passed through compressed gas at air inlet/outlet 11, compressed gas enters each inflated rubber pipe 14 along breather line 10, pressure
After contracting gas reaches the force value of regulation, close sealed valve 12 and carry out pressurize, and in rectangular frame, pour into a mould concrete, cast
After, use vibrations equipment to make bed die 15 shake, make concrete compaction, after concrete curing reaches final set strength, use true
Empty pump connects air inlet/outlet 11, outwards bleeds from breather line 10, produces negative pressure, inflated rubber pipe in making each inflated rubber pipe 14
14 outer walls depart from concrete voluntarily, take out in the hole that now can be formed from concrete slab by inflated rubber pipe 14 easily,
Realize the demoulding.The present invention uses inflated rubber pipe 14 as the casement of one-tenth punch die, and after concrete reaches final set strength, rubber fills
Trachea 14 can separate with concrete voluntarily, is not required to staff and operates casement when concrete reaches initial setting strength,
Will not damage xoncrete structure, be convenient in demoulding, yield rate is high, the inflation of inflated rubber pipe 14 and bleed all can be unified by equipment
Control, be conducive to being substantially improved the production efficiency of concrete core slab, reduced the labor intensity of workman, industry can be realized
Metaplasia is produced, and inflated rubber pipe 14 processing technique is simple, can be mass, and manufacturing cost is well below metal casement.First riser 7
With the length that the second riser 16 can limit inflated rubber pipe 14, prevent concrete cast time inflated rubber pipe 14 pressurized after
There is longitudinal extension, make the situation that casement diameter attenuates, it is ensured that the through-hole diameter of concrete core slab can reach to design requirement.
Inflated rubber pipe 14 two ends are socketed with mounting seat, and mounting seat is able to ensure that inflated rubber pipe 14 two ends keep shape, it is to avoid cast
During concrete, inflated rubber pipe 14 two ends are by concrete pressurizing and deformation.
The present invention, in order to improve the stability of rectangular frame, can use following structure: the 3rd side plate 3 Basolateral arranges
One horizontal flanging 17, the 4th side plate 4 Basolateral arranges the second horizontal flanging 18, the first side plate 1 bottom and the first riser 7 bottom
Between connected by the first horizonal base plate 19, by the second horizonal base plate between the second side plate 2 bottom and the second riser 16 bottom
20 connect, and first horizontal flanging 17, second horizontal flanging the 18, first horizonal base plate 19 and the second horizonal base plate 20 bottom surface are all and the end
Mould 15 contacts.This structure can be significantly increased the contact area of rectangular frame and bed die 15, rectangle frame when preventing bed die 15 from shaking
Frame is subjected to displacement, additionally it is possible to effectively prevent concrete to be extruded from the cooperation position between rectangular frame and bed die 15.
In order to strengthen the crush resistance strength of inflated rubber pipe 14, can suitably the wall thickness of inflated rubber pipe 14 be done greatly, but wall
Cause inflated rubber pipe 14 cannot shrink smoothly under suction function thicker than conference, increase demoulding difficulty.The present invention solves
Stating problem, can arrange convex tendon 21 by inflated rubber pipe 14 outer wall between the first side plate 1 and the second side plate 2, convex tendon 21 is along rubber
The length direction of gas tube 14 is arranged.Convex tendon 21 can inflated rubber pipe 14 by concrete extrusion time good supportive is provided, anti-
Only inflated rubber pipe 14 is deformed by concrete extrusion, inflated rubber pipe when inflated rubber pipe 14 is outwards bled, between convex tendon 21
14 sidewalls can deform under suction function, makes inflated rubber pipe 14 shrink smoothly.
Convex tendon 21 of the present invention can use various shape, the such as cross section of convex tendon 21 can be rectangle, triangle etc.,
The most preferably it is shaped as: the cross section of described convex tendon 21 is isosceles trapezoid.When inflated rubber pipe 14 shrinks, cross section is isosceles
The trapezoidal pressure between convex tendon 21 sidewall and concrete is relatively low, will not produce bigger frictional force, and ejection resistance is relatively low, and
Self-strength is higher, it is possible to provide bigger support force for inflated rubber pipe 14.
The present invention, in order to reduce the ejection resistance of inflated rubber pipe 14 further, can use following technical proposals: described convex
The angle of the angle α between two inclined-planes of muscle 21 is 40 °-60 °, and the junction of two inclined-planes and inflated rubber pipe 14 arranges half
Footpath is the fillet of 1mm-5mm.The program is ensureing that convex tendon 21 self has sufficient intensity, during the demoulding will not on the basis of breakage,
Pressure between convex tendon 21 sidewall and concrete is minimum, and ejection resistance is minimum, two inclined-planes and inflated rubber pipe 14 during the demoulding
The fillet of junction it can be avoided that during the demoulding concrete herein come off.
The cross section of the inflated rubber pipe 14 between the first side plate 1 of the present invention and the second side plate 2 can use various shape,
Such as:
Inflated rubber pipe 14 cross section between first side plate 1 and the second side plate 2 can be circle, Long Circle, pentagon or six limits
Shape.Circular inflated rubber pipe makes simple, rational in infrastructure survivable and easy maintenance, and during use, the demoulding is more convenient, becomes
The wallboard strength of type is higher.Wallboard quality after oblong inflated rubber pipe molding is lighter, installs casting concrete in hole when
More make wallboard almost be equal to cast-in-situ wall with agent structure stable connection, bigger hole be more convenient for hydroelectric line and
Other bigger equipment is laid and is installed.Pentagonal inflated rubber pipe makes simple, and after wall board forming, bond between fresh and hardened concretes is good, water
Electric line and other equipment are fixed easily location.Hexagonal inflated rubber pipe is in addition to having pentagon feature, and structure is more stable, system
The body of wall become is lighter.
