Embodiment Construction

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are explanations of the present invention and are not limited to the following examples.

[0034] For a construction project, the cross-sectional size of the arc beam 21 is 250mm×600mm, the arc radius of the outer edge of the arc beam is 16600mm, and the arc radius of the inner edge is 16350mm. 21 and floor 22 integral pouring.

[0035] The arc beam construction method for finalizing the formwork structure by means of adjustable arc beams includes the following steps:

[0036] Step 1. Combine the attached figure 1 As shown, the horizontal support 3 on both sides is connected by the crossbeam 8, and the beam bottom mold 7 is laid on the crossbeam 8. The horizontal support 3 adopts U-shaped channel steel, and the notch of the U-shaped channel steel faces downward. The upper surface of the horizontal support 3 is provided with a ...

Abstract

The invention relates to a construction method of an arc beam by using an adjustable arc beam molded formwork supporting structure. The construction method is characterized in that the construction method comprises the following steps of assembling a beam formwork, erecting a scaffold, installing the beam formwork, installing a floor bottom formwork, and pouring concrete and maintenance. Accordingto the construction method, a vertical rib is fixed on a beam bottom formwork in a screw mode, and fasteners on the back side of a beam side formwork are buckled on the vertical rib one by one to complete the radian adjustment of the beam side formwork; split bolts are pulled and knotted to complete the assembly of the beam formwork; the beam formwork is hoisted as a whole, a bottom horizontal support of the beam formwork is clamped to a short vertical column, and puller bolts abut against the vertical ridge on the side face of the beam formwork to complete the installation of the beam formwork in a support system; and then the floor bottom formwork is installed, and the concrete is poured. The construction method has the advantages of accurate radian, convenient installation, overall firmness, less consumables, high turnover utilization rate, high recovery utilization rate, and significant economic and technical benefits.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a method for constructing an arc-shaped beam by means of an adjustable arc-beam shaped formwork structure, which is applicable to the construction of arc-shaped beams in various forms of buildings and structures. Background technique [0002] In actual engineering, the construction of circular arc beams is quite difficult. The traditional formwork method is to cut the flat wood plywood into several small pieces, and then nail the small pieces of flat wood plywood together to form a whole close to the circle. arc formwork support system, the construction method has low formwork radian accuracy, and it is easy to waste materials, and the recycling rate of flat wood plywood is low, which increases the construction cost; During the pouring process, mold expansion and mold explosion are prone to occur, which affects the forming quality of the arc beam; in ...
