Abstract

The invention discloses an H-type prestressed concrete column and a production method thereof. The production method of the H-type prestressed concrete column comprises the following steps: (1) mixing materials; (2) preparing embedded parts, and carrying out mesh processing, main reinforcement grouping and nut processing; (3) cleaning up molds; (4) bundling meshes and main reinforcements; (5) closing molds; (6) positioning pre-embedded nuts; (7) tensioning the main reinforcements; (8) mixing concrete; (9) carrying out concrete injection molding; (10) forming specimen; (11) carrying out concrete secondary finishing; (12) maintaining; (13) testing concrete strength; (14) demolding finished products; (15) inspecting finished products; (16)marking finished products; and (17) mending the shape. The H-type prestressed concrete column obtained by the method has a column body made of cement, sand, stone, water and admixtures, and the meshes and bar reinforcements are embedded in the column body; and one surface of the column body is in a planar shape, and the pre-embedded nuts for fixing sound absorption / insulation boards are arranged in the column body.

Description

technical field [0001] The invention relates to the technical field of noise pollution prevention and control, in particular to a plug-in type sound barrier installed in highways, railways, elevated composite roads, light rails, subways, factories and the like for noise reduction. Background technique [0002] For the prevention and control of municipal noise pollution in highways, railways, elevated composite roads, light rails, subways, etc., the plug-in sound barriers composed of H-shaped steel columns and sound-absorbing / sound-insulating panels are generally used. However, H-shaped steel columns have the disadvantages of high cost, poor corrosion resistance, poor integration with the surrounding environment, and long construction period, so it is necessary to improve them. Contents of the invention [0003] The object of the present invention is to provide an H-shaped prestressed concrete column and its production method in view of the shortcomings of the prior art. Th...
