Description
Technical field
The utility model is related to building auxiliary equipment field, more particularly to concreting auxiliary equipment field, specifically
Say, be a kind of telescopic concrete shuttle groove.
Background technology
Using concreting shaping more than the basis of modern architecture, agent structure, this mode of building is built compared to tradition
Build, with preferable globality and higher rigidity, building build the scale of construction it is larger when, generally use pump truck pumped commercial concrete
Pour, when pouring, pump truck by pump line by concrete pumping to eminence, then fall from above, through material distributing machine export flow out, if
Concrete is directly fallen from above, and concrete is reached with relatively higher speed when pouring face, because the gravity of aggregate overcomes
The cohesive strength of storeroom, bulky grain aggregate substantially concentrates on side or bottom surrounding, is isolated so as to be separated with mortar, when
When freely toppling over height more than 2m, this phenomenon is especially apparent, and concrete mix will be isolated seriously.Use the concrete of isolation
Pour the coarse aggregate sinking in building constructure, concrete, fine aggregate to float, the concrete component for pouring shaping can be caused to occur
The adverse consequences such as surface appearance defects, component inside formation leakiness area, component inside reinforcing steel bars exposed, concrete strength will significantly
Degree declines, and the homogeneity of concrete is poor in addition, causes the contraction at each position of concrete inconsistent, is also easy to produce concrete shrinkage and splits
Seam, significantly reduces the endurance quality of the concrete such as concrete impervious, freeze proof；In addition, inside concrete formation leakiness is empty
Hole area, can cause internal reinforcing steel bar bear uneven, and reinforcing bar is directly exposed in air, easy-to-rust, has a strong impact on concrete structure
Bearing capacity, destroys the security performance of structure, it is serious the need for component removed, done over again, not only cause the wasting of resources, can more make
Into huge economic loss.
Occurring the segregation phenomenon caused by from eminence pump concrete during to avoid pouring, often assisting concrete using shuttle groove
Fall, and shuttle groove of the prior art being the characteristics of there is length to fix, inconvenience is moved, when carrying out concreting, shuttle groove
Covering pours that face is smaller, it is necessary to which multiple workmans coordinate frequently moves, and efficiency of construction is relatively low, and concrete has necessarily first
The solidifying time, thus concrete from mixer draw off after to pouring the perdurabgility finished no more than regulation, therefore how to improve
The efficiency poured is also technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of telescopic concrete shuttle groove, for solving shuttle flute length in the prior art
Degree is fixed, be not easy to move, to pouring the problem of efficiency produces harmful effect.
