Embodiment 1

[0033] Example 1: The volcanic stone sound insulation sound barrier / volcanic stone sound insulation sound barrier board for urban rail transit consists of a volcanic stone hollow frame 4 with a certain thickness, a plurality of conical volcanic stones 5 and a volcanic stone hollow frame and a plurality of conical volcanic stones. The cavity 6 formed by volcanic rocks constitutes. The porosity of the volcanic rock is 96%. The pores in the volcanic rock are naturally formed and uneven. The pore diameter can be 0.8 mm to 5 mm, the thickness is 20 mm to 50 mm, and the aspect ratio of the volcanic rock hollow frame 1 is 100: 100-20.

[0034] First select suitable volcanic stones and make a hollow brick-shaped hollow frame with a certain thickness and an aspect ratio of 100:100-20; place and assemble a plurality of conical volcanic stones 5 on the volcanic stone hollow frame 4, conical The bottom of the volcanic stone 5 is tightly stuck on the volcanic stone hollow frame body 4 t...

Embodiment 2

[0037] Example 2: The volcanic stone sound insulation sound barrier / volcanic stone sound insulation sound barrier board for urban highways consists of a volcanic stone hollow frame 4 with a certain thickness, multiple conical volcanic stones 5 and plate-shaped volcanic stone hollow frames 4 and multiple pieces The cavity 6 formed by the conical volcanic rock 5 constitutes. The porosity of the volcanic stone is 66%. The pores on it are naturally formed and uneven. The pore diameter can be 1mm to 10mm, the thickness is 10mm to 30mm, and the aspect ratio of the plate-shaped volcanic stone is 100:100-20.

[0038] First select suitable volcanic stones and make a hollow brick-shaped hollow frame 4 with a certain thickness and an aspect ratio of 100:100-20; place and assemble a plurality of conical volcanic stones 5 on the hollow brick-shaped volcanic stone hollow frame 4 The bottom of the conical volcanic stone 5 is tightly stuck on the upper plate volcanic stone of the volcanic s...

Embodiment 3

[0040] Example 3: The volcanic stone sound insulation sound barrier / volcanic stone sound insulation sound barrier board used in industrial factories is formed by a plate-shaped volcanic stone 4 with a certain thickness, a plurality of conical volcanic stones 5 , and a plate-shaped volcanic stone and a plurality of conical volcanic stones A cavity 6 is formed. The porosity of the volcanic stone is 20%, and the pores on it are naturally formed and uneven. The pore diameter can range from 0.8mm to 5mm, the thickness is 20mm to 50mm, and the aspect ratio of the plate-shaped volcanic stone is 100:100-20.

[0041]First select the appropriate volcanic stone and make it into a hollow brick shape with a certain thickness and an aspect ratio of 100:100~20; assemble multiple conical volcanic stones on the hollow brick-shaped volcanic stone, and the bottom of the conical volcanic stone should be clamped upwards. On the upper plate-shaped volcanic rock, its surface is flush with the up...

Abstract

The invention belongs to the technical field of sound elimination and noise reduction, and relates to a sound-proof noise barrier / sound-proof noise screen board used on two sides of highways and railways and inside factories, in particular to a sound-proof noise barrier / sound-proof noise screen made of natural volcanic rocks. The sound-proof noise screen board / sound-proof noise barrier disclosed by the invention is formed by a volcanic rock hollow frame and multiple conical volcanic rocks arranged in the volcanic rock hollow frame, wherein multiple through holes are formed in an upper surface board of the volcanic rock hollow frame; the multiple conical volcanic rocks are arranged in the through holes with the bottom parts upward; the bottom parts of the conical volcanic rocks are tightly and upwards clamped on upper slabby rocks of the hollow frame; the cone bottom parts of the conical volcanic rocks are flush with an outer wall of the upper surface board of the volcanic rock hollow frame; the cone top parts of the conical volcanic rocks are placed downwards; the top parts of the conical volcanic rocks are tightly and downwards clamped on lower slabby rocks of the hollow frame; and the top surfaces of the conical volcanic rocks are flush with the lower slabby volcanic rocks. Multiple pieces of volcanic rock sound-proof noise screen board / sound-proof noise barrier are mounted and fixed on a steel structure column in an upper-lower parallel stacked manner, and thus an integral sound-proof noise barrier / sound-proof noise screen board can be formed.

Description

technical field [0001] The invention relates to a sound-insulating sound barrier / sound-insulating sound-screen panel on both sides of roads and railways and in factory buildings, in particular to a sound-insulating sound barrier / sound-insulating sound-screening plate made of natural volcanic stone, and belongs to the technical field of noise elimination and noise reduction. Background technique [0002] In order to solve the problem of reducing and absorbing the noise on both sides of roads and railways and in factory buildings, the existing methods are to set up sound barriers / sound barriers on both sides of roads, railways and in factories, and reflect the noise through the sound barriers / sound barriers. Or absorption, to reduce the radiated noise generated by cars and trains running at high speed on roads and railways, and the noise generated by machine operation or mechanical processing in the factory building. [0003] Existing outdoor sound barrier boards / sound barrier...
