Exhaust device for pouring steel pipe concrete and its construction method

Abstract

A steel pipe concrete pouring exhaust device and its construction method, including a fixed frame, an exhaust pipe and a lower cone head; the fixed frame is T-shaped, including a horizontal bar and a vertical bar; Inserted in the steel pipe, the length of the exhaust pipe is adapted to the height of the concrete to be poured; the upper end of the exhaust pipe is sleeved on the vertical bar, and is connected with the vertical bar through the first bolt; on the wall of the exhaust pipe, There are exhaust holes spaced apart vertically, and the exhaust holes are inclined holes that gradually slope downward from the inside to the outside; the lower cone head is set at the bottom of the exhaust pipe and is conical; the tip of the lower cone head faces downward ; There is a connecting short rod in the middle of the top of the lower cone head; the connecting short rod is plugged into the lower end of the exhaust pipe and connected with the exhaust pipe through the second bolt. The invention solves the technical problems of cumbersome construction, uneven concrete pouring, uneven concrete pouring and uneven local stress at the vent hole of the steel column wall existing in the traditional construction method of pouring concrete.

Description

Technical field [0001] The invention belongs to the field of civil engineering, in particular a steel pipe concrete pouring exhaust device and its construction method thereof. Background technique [0002] With the rapid development of the construction industry, people also have a large demand for structures, and the steel pipe concrete structures come to life, and steel pipe concrete combination is an efficient material composite technology method, which can improve the load carrying capacity, toughness and durability of concrete. Sex. However, when the steel pipe concrete is poured, it is necessary to ensure the transmissibility of concrete, in response to this situation, the prior art opens gas hole on the steel column wall, and there is more inconvenient and risk in the steel column wall. First, when the steel column has a large wall thickness, regardless of the cumbersome process in the factory or on-site opening; two, due to the discharge gas hole on the steel column, 100mm...
