Integrated pouring device for installation of rail column type inspection pit fastening system

Abstract

The invention discloses an integrated pouring device for installation of a rail column type inspection pit fastening system. The periphery of a stand column reserved steel bar is wrapped by shaping aluminum formworks, wherein the two shaping aluminum formworks parallel to a steel rail above the reserved steel bar are higher than the other two shaping aluminum formworks at the positions perpendicular to the steel rail, and the shaping aluminum formworks are used for fixing a matched pouring funnel. The invention further discloses a laying method of the integrated pouring device. The integrated pouring device replaces traditional woodworking operation wasting time and materials, solves the problems that the formwork supporting effect is slow and parts are prone to contamination in the pouring process, and is short in construction period, low in use cost, convenient to construct, high in efficiency, good in stability and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an integrated pouring device for the installation of a column-type inspection pit fastener system in a professional track section. Background technique [0002] At present, the construction interface of conventional civil engineering and track professional is generally 50cm below the rail surface of the inspection pit. The reinforced concrete works below the interface shall be constructed by the civil engineering unit and the steel bars shall be reserved. Professionally done. The installation technical process steps of the existing column inspection pit fastener system in the railway or subway section are generally as follows: [0003] 1. First, the erection of the rail and the assembly of the rail row; [0004] 2. According to the requirements of the track laying drawings, assemble the iron backing plate, the rubber pad under the rail and the fastener...

AI Technical Summary

Problems solved by technology

[0009] 1. It is necessary to protect the fastener system, and it is time-consuming to bring plastic bags to the fasteners, and it is easy to damage the plastic bags, pollute the fasteners, and jam the bolts when the concrete is poured or vibrated;

[0010] 2. The area under the rubber pad (wooden board) is prone to vibration leakage due to the large turning radius of the vibrating rod. First, there are many floating paddles and low strength. Second, the surface is uneven. After the wooden board is removed and the rubber pad is replaced , there is a gap between the bottom layers of the rubber pad on the concrete finish surface, which affects the force transmission;

[0011] 3. Wooden formwork processing requires special cutting equipment, professional woodworkers, and auxiliary materials such as square wood when setting up the formwork, which is time-consuming and time-consuming;

[0012] 4. The size of the column is small, so the wooden formwork used for assembly is generally cut to a smaller size, and the recycling value is low. Generally, construction units incinerate more, which is not environmentally friendly
