Fine-adjustment support for support beam of bottom formwork of pile cap

Abstract

The invention discloses a fine-adjustment support for a support beam of a bottom formwork of a pile cap. The fine-adjustment support comprises a square pile, an exposed rebar, a chain, a fine-adjustment cushion block and a support body. The exposed rebar is arranged at the top end of the square pile, the chain is connected with the exposed rebar, the fine-adjustment cushion block is connected with the chain, and the support body is connected with the fine-adjustment cushion block. The support body is made of an L-shaped steel rod. The upper end of the support body is a threaded end which penetrates the fine-adjustment cushion block to be fixed by a nut. The nut is arranged at the upper end of the fine-adjustment cushion block. A steel beam retaining plate with an L-shaped section is mounted on the support body at the lower end of the fine-adjustment cushion block. A limiting plate is fixed at the tail end of the support body. A gap for holding the support beam is formed by encircling of the limiting plate, the support body and the steel beam retaining plate. The fine-adjustment support for the support beam has the advantages that a pile foundation serves as a fixing point, the height of the support beam is adjusted through loosening and tightening of a bolt, fine-adjustment precision can reach the millimeter level, and construction precision requirements are met completely; the fine-adjustment support is convenient to mount and rapid to adjust, construction quality is guaranteed, and construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to a fine-adjustment support for a pile cap bottom mold support beam. Background technique [0002] During the construction of the pile cap of the high-piled wharf, it is necessary to support the base form and install the support beam of the base form (the support beam is steel or wood). If it exceeds 10mm, because the construction on water is greatly affected by equipment, wind, waves, and tides, the installation of the support beam of the bottom form is often difficult to meet the accuracy requirements, or it will take a long time for repeated adjustments. At present, it is difficult to adjust the elevation of the bottom formwork of cast-in-place pile caps on water, and the accuracy is not suitable for control. The construction cost and efficiency are high and low by using the original clamping piles and hoops. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present inv...
