Description
Technical Field
The utility model belongs to the technical field of the wall body and specifically relates to a supplementary type steelframe of underground continuous wall notch is related to.
Background
The underground continuous wall is formed by digging a long and narrow deep groove on the ground, hoisting a reinforcement cage in the groove after cleaning the groove, then pouring underwater concrete by a conduit method to build a unit groove section, and thus, the steps are carried out section by section, and a continuous reinforced concrete wall is built underground. In the concrete pouring process of the underground continuous wall, due to improper operation, the concrete pouring amount is relatively overlarge, so that the upward return speed of the concrete is overlarge, and great upward impulsive force is generated, so that the guide pipe and the reinforcement cage are supported to float upwards; in addition, when the concrete has the quality problems of easy segregation, short initial setting time, large slump loss and the like, the flowability of the concrete is reduced after a little time, so that the initial concrete pouring at the upper part has the solidification tendency. When the fluidity is poor and even the condensed concrete surface contacts the bottom end of the reinforcement cage, the reinforcement cage is very easy to support to float, and if the floating of the reinforcement cage is not prevented, the construction quality of the underground continuous wall is greatly influenced.
Therefore, it is very important to find an auxiliary steel frame capable of preventing the steel reinforcement cage from floating.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiency among the prior art, provide an underground continuous wall notch auxiliary type steelframe.
The auxiliary profile steel frame for the notch of the underground diaphragm wall comprises a slide way, profile steel, a sliding wheel, an anti-floating top plate, a slide groove, a steel frame inclined strut and a top plate, wherein the sliding wheel is installed at the bottom of the profile steel, the profile steel is placed in the slide groove of the slide way, the steel frame inclined strut is welded at the top of the profile steel adjacent to the top of the profile steel to form a profile steel frame, the top plate is arranged at the top of the profile steel, the profile steel is fixed on the top plate to form a complete profile steel frame, and the anti-.
Preferably, the method comprises the following steps: the slide way is a double-slide-groove structure and is matched with H-shaped section steel.
The utility model has the advantages that:
(1) the utility model discloses an anti roof that floats on shaped steel steelframe can prevent that the steel reinforcement cage from floating.
(2) The utility model discloses set up the sliding wheel bottom shaped steel to place the slide bottom shaped steel, make shaped steel frame can slide along the slide, both improved the translation rate, can ensure again that shaped steel frame can not be toward other orientation squints.
