Abstract

A concrete sound insulation board comprises a sound insulation main board and a bearing post with insertion-type mounting grooves; and the sound insulation main board can be inserted into the mounting grooves quickly and can be superimposed to the corresponding height, and then is fixed quickly through spring bolts. The concrete sound insulation board is manufactured by C50 concrete, steel mesh, and U-steel for reinforcement; the concrete sound insulation board has the advantages of high strength, good durability, shock resistance, quickness in mounting, low construction cost and the like, and can be used as a sound insulation barrier for high-speed railway and expressway.

Description

The concrete sound barrier

Technical field

A kind of concrete sound barrier that is used for super expressway can be assembled into the concrete sound-proof wall quickly and easily, belongs to the precast unit field.

Background technology

Along with the fast development of high-speed railway and speedway, wheel that runs up and track and the huge noise that ground friction produced, increasing to the influence that peripheral resident's life and rest causes, the application of super expressway sound barrier (wall) is more and more general.The noise that the super expressway sound barrier can effectively reduce urban traffic and produced is for road periphery resident provides relatively quietly living environment.Available coagulation soil sound barrier (wall) is an ordinary reinforced concrete structure, and its strength grade of concrete is C30, splices through the i iron column between plate and the plate; Because it is relatively heavy, and splice loaded down with trivial detailsly, construction is very inconvenient; Particularly because of its intensity is low, poor durability is difficult to bear the HI high impact of high-speed railway, the effect of high suction wind pressure; And involve great expense, so be difficult to satisfy the demand of the high-speed railway and the speedway of present high speed development.

Summary of the invention

In order to overcome the deficiency of prior art, ad hoc counted a kind of simple in structure, easy to assembly, the concrete sound barrier of anti-high blast, splicing structure that durability is good.

It is a kind of simple in structure that the utility model provides, and assembly unit is the concrete sound barrier easily, and sound barrier is a reinforced concrete structure, constitute by sound insulation mainboard and bearing post, and supporting cornice mounting groove, the sound insulation mainboard can insert in the mounting groove fast, is superimposed to corresponding height.The sound insulation mainboard is a cube, and thickness is 50mm-100mm, is built with channel-section steel by C50 concrete, steel mesh reinforcement, reinforcement to form, and mainboard can freely superpose in short transverse, forms the sound-proof wall of different demands.Bearing post is " worker " font reinforced concrete structure, is made up of cylinder and steel sole plate, and bearing post master muscle inserts in the steel sole plate preformed hole and is weldingly connected with base plate.Bearing post both sides sunk part is the Fast Installation groove; Groove middle part prepared screw-bolt hole, outside embedded nut, mainboard can insert in the mounting groove easily; Link to each other with bearing post apace through spring bolt, be assembled into super expressway (railway, the highway) sound-proof wall of various height random lengths quickly and easily.

The advantage of the utility model is by C50 concrete, steel mesh reinforcement and strengthens watering the sound insulation mainboard that builds up with channel-section steel; Have advantages such as intensity height, anti-HI high impact, high suction blast; Adopt the quick-assembling structure can significantly reduce the on-site installation work amount; The spring bolt method of attachment can reduce the structure results in premature failure that is caused by vibration, improves durability, thereby has characteristics such as integrated cost is low, defening effect is good.

Description of drawings

Be the description of drawings of the utility model below, Fig. 1 is the organigram of sound barrier, and [1] is concrete; [2] be sound barrier master muscle, [3] are the sound barrier stirrup, and [4] are channel-section steel; Fig. 2 is a sound barrier arrangement of reinforcement sketch map, and Fig. 3 is the bearing post structural representation, and [5] are the bearing post lengthways main steel bar; [6] be outside stirrup, [7] are inner stirrup, and [8] are the longitudinal structure muscle.Fig. 4 is bearing post steel sole plate figure, and [9] are bearing post and base plate connecting hole.

The specific embodiment

The specific embodiment of the utility model is described now, to make length 3000mm, height 500mm; The sound barrier of thickness 70mm is an example, and like Fig. 1, shown in Figure 2, mainboard selects for use 10 Φ, 8 horizontal main muscle and 16 Φ 4 stirrups to constitute three-dimensional steel mesh reinforcement; No. 10 channel-section steels that channel-section steel adopts height 500mm are strengthened at two ends, and steel mesh reinforcement, reinforcement channel-section steel fuse with welding manner, with C50 concreting moulding; The overall dimensions of " worker " font bearing post are height 2000mm, width 200mm, thickness 300mm; Base plate adopts 300 * 200 * 10 A3 steel, above as shown in Figure 4ly have 8 Φ 13 holes and be used for linking to each other with the lengthways main steel bar of bearing post, the bearing post steel mesh reinforcement is as shown in Figure 3 to be made up of 8 Φ 12 lengthways main steel bars, 4 Φ 8 longitudinal structure muscle, 11 Φ 4 outside stirrups and 21 Φ 6 internal layer stirrups; The degree of depth of intermediate groove is 50mm, and width is 103mm, and short transverse is pre-buried 8 layers of M14 nut altogether; Reserve 8 layers of Φ 16 hole, every layer of nut and preformed hole quantity are two, each one on two limits.Every sound insulation mainboard is fixed on two bearing posts through four spring bolts.Supporting is with C50 concreting moulding.During installation sound barrier is inserted in the groove of bearing post, with the spring bolt of M14 sound barrier is fixed on the bearing post, per two bearing posts and four sound barriers can be assembled into one section high 2 meters sound-proof wall.Bearing post of every increase and four sound barriers can increase a long measure, but quick-assembling becomes the sound-proof wall of Len req.

Claims

1. a concrete sound barrier is made up of sound insulation mainboard and bearing post, it is characterized in that supporting the cornice mounting groove, and the sound insulation mainboard can insert in the mounting groove fast, is superimposed to corresponding height.

2. like the concrete sound barrier of claim 1 as stating; It is characterized in that described bearing post is a reinforced concrete structure; External form is " worker " font, and the both sides sunk part is a mounting groove, mounting groove middle part prepared screw-bolt hole; Outside embedded nut, bearing post master muscle inserts in the steel sole plate preformed hole and is weldingly connected with base plate.

3. like the concrete sound barrier of claim 1 as stating, the mainboard that it is characterized in that insulating against sound links to each other with bearing post through spring bolt after inserting mounting groove.
