Electric sliding formwork formwork trolley for integral culvert wall pouring without tie rods

Abstract

The invention discloses an electric sliding formwork trolley for integral culvert wall pouring without tie rods. The formwork trolley includes a trolley and formworks located symmetrically on both sides of the trolley. The formwork includes an outer mold, an inner mold and an end mold. A first pull rod is arranged between the outer mold and the inner mold, and the trolley includes a traveling device, a reinforcing device, a supporting device, and a lifting device. The formwork system of the electric tie-bar-less formwork trolley of the present invention is assembled and formed once, recycled, and easy to turn around. The formwork trolley has less labor input during operation, high construction efficiency, good appearance quality, and high safety factor, which greatly reduces the cost of steel pipe supports. The amount of erection is higher, the safety standardization is higher, and the construction progress can reach one cycle per day; the electric tie-bar-free formwork trolley of the present invention effectively avoids the problem of water seepage in the tie-rod holes of the wall caused by the construction of culverts with traditional equipment, and solves the problem of obvious formwork seams and poor construction Quality defects such as staggered platform and concrete color difference ensure the flatness of the large surface of the culvert wall and the quality of the project entity.

Description

technical field [0001] The invention relates to a formwork trolley for pouring culvert walls, in particular to an electric sliding form trolley for integral culvert wall pouring formwork without tie rods. Background technique [0002] The engineering volume of the cast-in-place wall of the culvert is relatively large, and the construction of the wall is carried out by using the combination of conventional steel pipe supports and plane formwork. There are irregularities around the tie rod holes, dew sand, and water leakage in the tie rod holes. It takes a lot of manual work to polish the wrong platform, block the tie rod holes, waterproof the tie rod holes, and apply waterproof asphalt coating on the back of the wall. Contents of the invention [0003] The object of the present invention is to provide an electric sliding form trolley for integral culvert wall pouring formwork without tie rods. The trolley is hoisted and fixed on the outer mold and the inner mold through the...
