Cast-in-place column top closed horn mouth device and construction method thereof

Abstract

The invention discloses a cast-in-place column top closed horn mouth device and a construction method thereof. The horn mouth device comprises a concave plate, side plates connected to the outer side face of the concave plate and located on the two sides of a concave opening, inclined supporting pieces connected to the outer side edges of the side plates and connected to the concave plate, a movable plate connected between the two inclined supporting pieces, fixing pieces inserted between the two side plates and butt joint pieces connected between the fixing pieces, wherein the bottom of the movable plate is movably connected with the concave plate. According to the cast-in-place column top closed horn mouth device and the construction method thereof, through a horn mouth composed of the side plates and the movable plate, the pouring quality is ensured, and secondary chiseling is avoided; the horn mouth device is integrated, and split manufacturing and mounting are facilitated; through the arrangement of the fixing pieces and supporting pieces, lateral reinforcing is facilitated; and through the arrangement of blocking strips, lateral limiting is facilitated, and the sealing effect is achieved; through the arrangement of positioning grooves in the movable plate and positioning strips on the fixing pieces, the movable plate can be further fixed; and through the arrangement of clamping strips on the inclined supporting pieces, the movable plate can be temporarily fixed during pouring.

Description

technical field [0001] The invention belongs to the technical field of column construction, in particular to a device for closing a bell mouth at the top of a cast-in-place column and a construction method thereof. Background technique [0002] Cast-in-place construction is often used in the column construction of construction projects, especially the structural columns have strict quality requirements for pouring. In the pouring process, it is indispensable to assemble the column formwork, but when the column is too long and too high, it is necessary to set a bell mouth on its side for staged lateral pouring. At this stage, when constructing the top of the secondary structural column, an assembled non-movable 45~60° bell mouth is used. The bell mouth is set to ensure that the bottom vibrating rod has insertion space, and the top can be filled and sealed to ensure connection. However, in the existing horn construction, it is laborious to support the formwork at the horn mou...
