Abstract
The invention discloses a vibration-free self-compacting concrete homogenizer for a pipe core. The homogenizer comprises a diversion cone, diversion side plates are uniformly distributed on the outer conical surface of the diversion cone, and the diversion side plates are inverse V-shaped steel plates; and the clearance between the outer lateral surfaces of every two diversion side plates forms a blanking port, and an ejector rod is arranged at the top of the diversion cone. The homogenizer has the advantages that: centralized blanking of concrete is effectively realized; the quality defects that the concrete is segregated and layered in the absence of external force vibration, the air in the concrete cannot be effectively discharged and the concrete is not compacted and the like in the prior art are overcome; self-compacting function of the concrete is realized; and after the self-compacting concrete is poured, the quality of the finished product of the pipe core meets the standard requirement.
Description
Technical field
The present invention relates to a kind of concrete discharging instrument, especially relate to the vibration-free self-compacting concrete homogenizer for pipe core of a kind of Prestressed concrete cylinder pipe (PCCP).
Background technology
The tube core concrete formation of PCCP pipe is divided into two kinds of main production patterns according to its model characteristics: a kind of is the horizontal centrifugal moulding process, and PCCPL type Prestressed concrete cylinder pipe adopts this technique to produce; A kind of is the vertical pouring moulding process, and PCCPE type Prestressed concrete cylinder pipe adopts this technique to produce.Horizontal centrifugal moulding process principle is for adopting plastic concrete, and the centrifugal force that utilizes the pipe die High Rotation Speed to produce makes the concrete compaction moulding; Vertical pouring moulding process principle is for adopting the inside and outside pipe die cast concrete of liquid concrete utilization and making the concrete compaction moulding by the dither that is attached on the pipe die.More than two kinds of pipe of concrete core molding process, its concrete compaction principle is all by external force and makes each component of inside concrete self produce extruding to get rid of unnecessary moisture, air and particle voids in the concrete mix, to reach the purpose of concrete compaction.Namely in the process of concrete compaction, must apply outer active force so that concrete reaches closely knit effect to concrete mix by mode centrifugal or vibration, in this process, will produce higher energy consumption, the simultaneously certain noise pollution of inevitable generation.
Self-compacting concrete (self-compacting concrete is SCC) vibrates without external force in casting process, only depend on gravity can pass through the reinforcing bar gap, each corner of closely knit filling template forms uniformly densely structure, and bleeding, aggregate are not emanated in casting process.It shows good service behaviour in construction, concrete need not to vibrate in casting process and relies on Action of Gravity Field freely to trickle fully and the abundant space in the filling template, after the concrete hardening, because therefore its closely knit filling has better mechanical property and endurance quality than normal concrete.
The pipeline that utilizes the self-compacting concrete moulding is to adopt the mode of vertical pouring to realize: the PCCP mould that namely is comprised of base, internal mold, external mold and backform, concrete mix by the harmonious material device blanking, makes concrete flow into the concrete casting injection forming of realizing tube core in the space that is formed by base, internal mold and external mold from the mould top.
Owing to there are the design features such as cast highly high (height is more than or equal to 5m), blanking width wide (width is the pipe girth) during PCCP tube core concrete formation, therefore, adopt existing blanking tool and cutting mode (concrete is along the blanking of pipe die even circumferential) to be difficult to guarantee that the rear tube core end product quality of self-compacting concrete cast satisfies standard-required.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of vibration-free self-compacting concrete homogenizer for pipe core, realized the concrete unified allocation of materials to lower units, guaranteed that the rear tube core end product quality of self-compacting concrete cast satisfies standard-required.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vibration-free self-compacting concrete homogenizer for pipe core, comprise deflection cone, and be evenly equipped with the water conservancy diversion side plate at the male cone (strobilus masculinus) of described deflection cone, described water conservancy diversion side plate is reverse V-shaped steel plate; Gap between the lateral surface of per two blocks of water conservancy diversion side plates forms feed opening, is provided with push rod at the vertex of a cone of deflection cone.
Male cone (strobilus masculinus) bottom at deflection cone is evenly equipped with fixed card.Described water conservancy diversion side plate is four or more.Described fixed card is more than 12 or 12.
Compared with prior art, good effect of the present invention is: effectively realized the concrete unified allocation of materials to lower units by harmonious material device of the present invention, having solved when adopting prior art concrete can not effectively get rid of and the mass defect such as concrete leakiness at the segregation layering that does not have to occur in the situation of external force vibration, concrete Air, realized concrete self-compaction function, guaranteed that the rear tube core end product quality of self-compacting concrete cast satisfies standard-required.
Description of drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is A-A cutaway view of the present invention;
Fig. 2 is floor map of the present invention.
The specific embodiment
A kind of vibration-free self-compacting concrete homogenizer for pipe core as depicted in figs. 1 and 2, comprising: deflection cone 1, water conservancy diversion side plate 2, fixed card 3, push rod 4 and feed opening 5.
Uniform four or more water conservancy diversion side plate 2 on the male cone (strobilus masculinus) of deflection cone 1, described water conservancy diversion side plate 2 is reverse V-shaped steel plate; Gap between the lateral surface of per two blocks of water conservancy diversion side plates forms feed opening 5, in the uniform fixed card 3 more than 12 or 12 in the male cone (strobilus masculinus) bottom of deflection cone 1, is used for harmonious material device reliably fixing on backform; The vertex of a cone at deflection cone 1 is provided with push rod 4, is used for the top-opening door of jack-up hopper, so that concrete material leaks down from hopper, and the beginning blanking; Concrete material in lateral surface (being feed opening 5) the injection pipe die and the cavity between the steel cylinder of water conservancy diversion side plate, reaches the purpose of the unified allocation of materials to lower units by the male cone (strobilus masculinus) of deflection cone 1.
Operation principle of the present invention is: by the cooperation of deflection cone 1 and water conservancy diversion side plate 2, so that the self-compacting concrete material can only be by feed opening 5 unified allocation of materials to lower units (rather than even blanking of male cone (strobilus masculinus) from whole deflection cone of the prior art) to the deflection cone male cone (strobilus masculinus), like this, flow to the space of pipe die by gravity again from the concrete material of feed opening 5 unified allocation of materials to lower units, can effectively discharge air in the pipe die space (because the reverse V-shaped opening part of every block of water conservancy diversion side plate does not have concrete material, so that the air in the pipe die space can be discharged from these outward openings), can make again by entrained air not in the concrete of feed opening 5 unified allocation of materials to lower units, effectively finish the filling of self-compacting concrete, closely knit.
