Abstract
The utility model discloses an H-shaped pre-stressed concrete column which is provided with a column body; a mesh and a reinforcing steel bar are buried in the column body; one surface of the column body is in a plane shape; and a pre-embedded nut for fixing a sound-absorbing/-insulating board is arranged in the column body. The H-shaped pre-stressed concrete column can fully substitute an H-shaped steel column, and is characterized by high strength, corrosion resistance, freeze thawing resistance, maintenance-free, good integration effect with the surrounding environment, short construction cycle and the like.
Description
Technical field
The utility model relates to noise pollution Prevention Technique field, especially relates to being installed on the board plug type sound barrier that speedway, railway, overhead composite road, light rail, subway, factory etc. locate to be used for noise reduction.
Background technology
The board plug type sound barrier that is made of H steel column and suction/sound insulating panel is generally adopted in the control of traffic such as speedway, railway, overhead composite road, light rail, subway municipal administration noise pollution.But there is the shortcoming of cost height, not corrosion-resistant, poor with the syncretizing effect of surrounding environment and long construction period in the H steel column, is necessary to be improved.
The utility model content
The purpose of this utility model is the weak point that exists at prior art and a kind of H type prestressed concrete column is provided, this H type prestressed concrete column can substitute the H steel column fully, has characteristics such as intensity height, corrosion-resistant, freeze thawing resistance, non-maintaining, effective with surroundings, short construction period.
For achieving the above object, H type prestressed concrete column of the present utility model has a cylinder, is embedded with net sheet and reinforcing bar in the cylinder, and the wherein one side of cylinder is plane, is provided with the embedded nut that is used for fixing suction/sound insulating panel in it.
Described cylinder is an arc surface towards the another side of sound source.
One end of described cylinder offers lifting eye.
Compared with prior art, H type prestressed concrete column of the present utility model has following advantage: (1) use cost is lower than H steel column, good looking appearance, and visual impression is soft, can improve the degrees of fusion of sound barrier engineering and surrounding environment; (2) fireproof performance: fireproof performance all meets the regulation of GB8624-2006, and fire-protection rating reaches the A1 level; (3) physical property: compressive strength, flexural strength, breaking load etc. all meet the pertinent regulations of relevant criterion; (4) endurance quality: all have corrosion-resistant, humidity, anti-ly go mouldy, the ability of anti-thawing, H type prestressed concrete column is owing to adopt the alkali breeze concrete technology, can suppress concrete frost heave cracking effectively, be of value to concrete under low temperature environment, the raising of freeze thawing resistance durability, under all weather conditions, do not go mouldy, aging, indeformable.Be particularly suitable for the sound barrier engineering that specific (special) requirements arranged to anticorrosion, freeze proof; (5) installation and maintenance: H type prestressed concrete column can be increased work efficiency greatly, shortens the engineering time, reduces the site operation expense.

The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See that Fig. 1 is to shown in Figure 4: H type prestressed concrete column of the present utility model has a cylinder 10 of being made by cement, sand, stone, water and Admixture, and the appearance and size of cylinder 10 is 300mm * 300mm * L (L is a length, can determine according to the job site); Be embedded with net sheet and reinforcing bar 11 in the cylinder 10, the wherein one side 101 of cylinder 10 is plane, is provided with the embedded nut 12 that is used for fixing suction/sound insulating panel 20 in it.For improving the visual effect of H type prestressed concrete column, cylinder 10 is an arc surface towards the another side 102 of sound source.Under the prerequisite of the mechanical property that guarantees H type prestressed concrete column and intensity, rigidity and stability, to install and transportation for convenient, an end of cylinder 10 is provided with a lifting eye 13.
See Fig. 5 and shown in Figure 6: the basis of H type prestressed concrete column is adopted and is enlarged basis 30 (also can adopt hand excavated pile), enlarging the basis 30 inner 400mm * 400 * 1000mm rims of a cup of reserving, adopt crane that cylinder 10 is put into rim of a cup, proofread and correct, in rim of a cup, pour into thin real concrete.Cylinder 10 is main bearing member of sound barrier, and it is fixing by enlarging basis 30; Cylinder 10 sections are " H " shape.It is fixing that suction/sound insulating panel 20 passes through connecting bolt 40 and pressing plate and cylinder 10, and the space between cylinder 10 and the suction/sound insulating panel 20 is filled airtight with cement mortar or rubber strip.Steel Structure Installation materials such as connecting bolt 40 adopt the galvanizing by dipping preservative treatment.
Advantage of the present utility model is as follows:
(1) this product adopts Prefabrication, can greatly shorten site operation amount and construction period.
(2) H type prestressed concrete column is arc modeling near the sound source side, can make the sound barrier good looking appearance, and visual impression is soft, can improve the degrees of fusion of Noise Barrier Works and surrounding environment.
(3) H type prestressed concrete column has been reserved every (suction) sound plate hold-down nut, can guarantee during installation every (suction) sound plate upper thread bar smoothness, and is smooth.
(4) H type prestressed concrete column can select optimal coloured cement to make as required, coordinates mutually with view on every side.
(5) H type prestressed concrete column mainly adopts concrete and heatproof good weatherability, aging-resistant material. Have in light weight, intensity is high, corrosion-resistant, freeze thawing resistance, do not fire, the characteristics such as water absorption rate is low. Satisfy the technical requirement that uses under Line for Passenger Transportation, bridge and the open-air harsh weather fully. Do not need manual maintenance, maintenance after building up. Can reach more than 30 years service life.
