Construction method of concrete spreader supporting structure on hollow floor

Abstract

The invention discloses a construction method of a concrete spreader supporting structure on a hollow floor, and belongs to the technical field of cast-in-place concrete hollow floor construction. Theconstruction method comprises the following steps that (1) a concrete pouring scheme is determined, and all set positions of a concrete spreader are determined; (2) winding is accurately conducted ona floor bottom form, and bottom-layer reinforcing steel bars are bound; (3) concrete cushion blocks A, concrete cushion blocks B and a gypsum mold box are placed on the floor bottom form; (4) surface-layer reinforcing steel bars are bound; and (5) four supporting leg supporting frames are erected according to the positions of supporting legs of the concrete spreader, the supporting leg supportingframes are placed on the concrete cushion blocks A, and the gypsum mold box is arranged on the inner sides of the supporting leg supporting frames. According to the construction method, it can be guaranteed that the concrete spreader can be normally arranged, the gypsum mold box is effectively protected, the construction progress can be accelerated, the construction quality can be guaranteed, andthe construction cost can be reduced.

Description

technical field [0001] The invention relates to a construction method for a concrete distributor support structure on a hollow floor, and belongs to the technical field of cast-in-place concrete hollow floor construction. Background technique [0002] In order to reduce the formwork consumption and damage of hollow floors and slabs, and improve the fire resistance, sound insulation, heat insulation, anti-vibration and anti-interference performance of hollow floors and slabs, gypsum mold boxes have been widely used in cast-in-place concrete hollow floors. , Floor construction. The placing machine is a new type of construction machinery used in conjunction with the concrete delivery pump. It is the supporting equipment of the concrete delivery pump. It is connected with the concrete delivery pump to expand the range of concrete pumping. Its function is to send the pumped concrete to the In the formwork of the component to be poured. The concrete placing machine can improve t...

Problems solved by technology

[0004] However, if this fixing device is used for hollow floor or hollow floor slab construction, it is impossible for the four uprights to be placed in the installation gap between the gypsum mold boxes every time. If the upright poles interfere with the gypsum mold boxes, the fixed The device cannot be installed normally; the roof formwork is placed on the gypsum formwork box, and the gypsum formwork box will be damaged under the repeated load of the distribution machine; if the plaster formwork box on the lower side of the roof formwork or the lower side of the vertical pole is removed first, the surrounding concrete pouring is completed After that, install the removed gypsum formwork box and pour concrete again. The secondary concrete pouring and secondary installation of gypsum formwork box will affect the construction progress and construction quality, and increase the construction cost.
