Description

Technical Field

[0001] This utility model belongs to the field of sound barrier technology, specifically relating to a prefabricated assembly component for a fly ash ceramsite ecological sound barrier bridge. Background Technology

[0002] Existing bridge installation methods employ two main approaches: One is the saddle-shaped joint, which requires partial cutting of the protruding portion of the crash barrier, increasing workload, affecting aesthetics, and compromising the integrity of the original crash barrier. Furthermore, due to the varying widths of bridge crash barriers, a standardized joint cannot be used; on-site measurement, cutting, and welding are necessary. The other approach uses a side-mounted joint, which eliminates the need to cut the protruding portion of the crash barrier, but suffers from severe eccentricity in the load-bearing system and insufficient bending resistance. Both methods involve on-site welding, significantly extending the construction period. Moreover, on-site welding makes it more difficult to guarantee quality compared to factory-processed standard parts. Utility Model Content

[0003] To address the aforementioned technical issues, this utility model optimizes the on-site installation and splicing nodes, providing a prefabricated assembly component for fly ash ceramsite ecological sound barrier bridges. This overcomes the shortcomings of existing technologies involving on-site material cutting and welding. Consequently, it reduces installation costs and time, improves installation efficiency, optimizes the structural stress system, and aligns with the concept of low-carbon and environmentally friendly construction.

[0004] The prefabricated assembly of the fly ash ceramsite ecological sound barrier bridge is composed of H-beams 1, inverted L-shaped bases 3, ribs 2, and anchor bolts. The side panel of the inverted L-shaped base 3 has four strip-shaped holes 9, through which four horizontal anchor bolts 4 are passed and tightened with matching double nuts 5. The top panel of the inverted L-shaped base 3 is tightened with two vertical anchor bolts 6 and matching double nuts 5, with a pad 7 placed between the double nuts 5 and the top panel. The H-beams are vertically welded to the top panel of the inverted L-shaped base 3, and four ribs 2 are welded between the two corners of the H-beams and the top panel of the inverted L-shaped base 3 for reinforcement. Multiple prefabricated assembly of the fly ash ceramsite ecological sound barrier bridge are assembled at intervals, and the fly ash ceramsite ecological sound barrier 8 is tightly clamped between two adjacent H-beams 1.

[0005] The horizontal and vertical anchor bolts are drilled into the bridge crash barrier or shoulder retaining wall, and after tightening the double nuts, they are fixed in place by spot welding. This prevents loosening and subsequent joint failure.

[0006] The ribs are irregularly shaped, which improves the wind load capacity of the nodes while effectively reducing the amount of material used.

[0007] The H-beams, inverted L-shaped bases, ribs, and anchor bolts are all galvanized for corrosion protection.

[0008] The self-weight of the fly ash ceramsite ecological sound barrier 8 is no more than 50 kg / m³, and the standard value of wind pressure load is no more than 1.0 KN / m².

[0009] The H-beam is of model number HW125*125*6.5*9.

[0010] The inverted L-shaped base is L300*250mm, 280mm wide, and 18mm thick.

[0011] The anchor bolts are of type M24, with a horizontal anchor bolt length of 220mm and a vertical anchor bolt length of 300mm.

[0012] The fly ash ceramsite ecological sound barrier 8 has a height of 2m and a span of 2m.

[0013] This utility model designs a prefabricated assembly component for a fly ash ceramsite ecological sound barrier bridge. This component is a standard prefabricated part, uniformly processed. It boasts advantages such as low carbon footprint and environmental friendliness, convenient installation, aesthetically pleasing appearance, good overall integrity, stable and non-displaceable connections, and high durability. Compared with existing technologies, it achieves benefits such as material savings, reduced weight, efficient on-site assembly, stable load-bearing system, reduced on-site processing, and lower construction costs, significantly accelerating construction and installation progress while reducing on-site environmental pollution.
