Detailed description of the invention
Referring to accompanying drawing, the composition to the preferred embodiments of the present invention and effect are elaborated as follows.At this, should be careful the reference symbol that the element of each accompanying drawing is enclosed, for identical element, clock in different accompanying drawing acceptances of the bid, carry out mark with identical symbol as far as possible.
Fig. 1 is the figure of noise barrier according to an embodiment of the invention.Fig. 2 a to Fig. 2 f is the schematic diagram that illustrates successively the noise barrier of one embodiment of the present of invention or the construction method of retaining wall.
Noise barrier is under normal circumstances along the edge setting of road etc., plays and prevents that noise that vehicle produces is diffused into the division board effect of road surrounding area.Retaining wall refers to the native sand pressure of opposing, prevents the wall body structure that earth collapses.Noise barrier and retaining wall although that object is set is different, there is haply similar shape.
As shown in Figure 1, noise barrier or retaining wall 10 (hereinafter referred to as noise barrier) are constructed with the shape of elongated division board, and extend for realizing stable support along continuous straight runs its underpart, is roughly L font.Noise barrier 10 arranges reinforcing bar therein for ruggedized construction, and to construct around the concrete form of above-mentioned reinforcing steel bar laying.At this, noise barrier uses implication to comprise the retaining wall with similar shape.
The construction of noise barrier in the past, through mould being set in order to meet the shape of noise barrier, is again removed the process of mould after the fluid concrete of the inside of mould again.But above-mentioned existing method has following problem: arrange and remove mould required time and grow and make integral construction time lengthening, thereby cause labour cost to increase.
In the present invention, provide one to utilize movable mould and concrete placer, the method for noise barrier is set with quick and lower operating expenses by mechanization construction technology.Concrete placer is a kind of equipment together using with the movable mould of the type frame as sound insulating wall structure, for example, have the equipment that is called slip form paver.When operation, movable mould and concrete placer together move, and now concrete placer moving in penetration concrete in movable mould.
The height that utilizes movable mould and concrete placer once can construct exists limitation.Therefore, for example,, when in the situation that the height of noise barrier is 3m, use movable mould and the concrete placer height of whole 3m of can not once constructing, but by the mode being layering, need to just can fulfil assignment through twice or three times.
In the situation that fulfiling assignment through twice construction, for example at first can be with the height of the 2m elementary noise barrier of constructing, above elementary noise barrier, the form with the height construction secondary noise barrier of 1m fulfils assignment afterwards.In the situation that fulfiling assignment through three times, for example, at first with the height of the 1.3m elementary noise barrier of constructing, afterwards above elementary noise barrier with the height construction secondary noise barrier of 0.9m, above secondary noise barrier, the form with three grades of noise barriers of height construction of 0.8m fulfils assignment afterwards.
Referring to Fig. 2 a to Fig. 2 f, the method to set up of the noise barrier to one embodiment of the present of invention describes.In the present embodiment, adopt the noise barrier of 3m height through the method for three times constructions.
With reference to Fig. 2 a, first at ground 1 upper concrete floor 31.Concrete floor 31 is to provide basic part in order works to be set on ground 1.
Secondly, the first reinforcing bar 32 is set on concrete floor 31.The first reinforcing bar 32 is for ruggedized construction, as the part that is included in inside concrete, according to the shape setting of noise barrier.
Secondly, with reference to Fig. 2 b, on the fluid concrete basis, bottom 33 of the first reinforcing bar 32, to fix the first reinforcing bar 32.If the first reinforcing bar 32 is not fixed, in the time that movable mould moves, the position change of the first reinforcing bar 32, and the noise barrier of the required form of cannot constructing.For example, the height of concrete foundation 33 can be 15cm.
Fig. 2 c is the view illustrating on the fluid concrete basis, bottom 33 of the first reinforcing bar 32.Now, the upper end 32a of the first reinforcing bar 32 is formed as the state of along continuous straight runs bending.By as described below the reason of the upper end 32a along continuous straight runs bending of the first reinforcing bar 32, after the elementary noise barrier of constructing, be connected with second reinforcing bar on the top that is positioned at the first reinforcing bar 32.
Secondly,, with reference to Fig. 2 d, utilize movable mould and the concrete placer elementary noise barrier 34 of constructing.The height of elementary noise barrier 34 comprises concrete foundation 33 parts, can be about 1.3m.
Fig. 3 illustrates the view of utilizing movable mould and concrete placer construction noise barrier.At this, the first movable mould 100 refers to the mould that meets the shape of elementary noise barrier 34 and make.Concrete placer 2 can be by appts. for transferring ready-mixed concrete 2a to the interior injection concrete of the first movable mould 100.The first movable mould 100 connects concrete placer 2, in the time that concrete placer 2 moves, together moves.Concrete placer 2 moves to the interior continuous injection of the first movable mould 100 is concrete by appts. for transferring ready-mixed concrete 2a simultaneously, and the concrete of injection forms the shape of elementary noise barrier 34 by the first movable mould 100.
Again with reference to Fig. 2 d, elementary noise barrier 34 is positioned at the part of below of noise barrier, can be L font.Now, the first reinforcing bar 32 protrudes to the top of elementary noise barrier 34 slightly with the state of its upper end bending.This is that the first reinforcing bar 32 is difficult to be connected with the second reinforcing bar that is located thereon portion because if the state that concrete is imbedded elementary noise barrier 34 inside completely with the upper end of the first reinforcing bar 32 is while solidifying.
Secondly,, with reference to Fig. 2 e, by vertically stretching the upper end of the first reinforcing bar 32 of bending, be connected with the second reinforcing bar 35 that is positioned at the first reinforcing bar 32 tops.If the first reinforcing bar 32 separates with the second reinforcing bar 35, the structural strength of noise barrier reduces, and therefore needs the first reinforcing bar 32 to be connected with the second reinforcing bar 35.
In the present embodiment, the first reinforcing bar 32 is connected in the mode of overlap joint with the second reinforcing bar 35.Overlap joint is to instigate the first reinforcing bar 32 and the second reinforcing bar 35 overlapping and be hooked the connected mode of utilizing conjunction that lap (P1) is carried out to combination with certain length.The length of lap (P1) can be for example 30 to 50cm.
Secondly,, with reference to Fig. 2 f, utilize the second movable mould (not shown) and concrete placer construction secondary noise barrier 36.The second movable mould is made according to the shape of secondary noise barrier 36.The height of secondary noise barrier 36 can be about 0.9m.Now, the second reinforcing bar 35 protrudes to the top of secondary noise barrier 36 slightly with the form of its upper end bending.This be because if concrete so that the upper end of the second reinforcing bar 35 when imbedding the state of secondary noise barrier 36 inside completely and solidifying, be difficult to be connected with the 3rd reinforcing bar 37 that is positioned at the second reinforcing bar 35 tops.
Suppose, the noise barrier of 3m height uses the method through twice construction, and the height of elementary noise barrier 34 is made as to 2m, and the height of secondary noise barrier 36 is made as 1m and can completes construction.Now, the second reinforcing bar 35 is rendered as the form being included in completely in secondary noise barrier 36, and the shape of the second movable mould is also slightly different thus.
After secondary noise barrier 36 completes construction, by vertically stretching the upper end of the second reinforcing bar 35 of bending, be connected with the 3rd reinforcing bar 37 that is positioned at the second reinforcing bar 35 tops.The second reinforcing bar 35 is connected by the mode of overlap joint with the 3rd reinforcing bar 37.
Secondly, utilize the 3rd movable mould (not shown) and three grades of noise barriers 38 of concrete placer construction.The 3rd movable mould is made according to the shape of three grades of noise barriers 38.The height of three grades of noise barriers 38 can be about 0.8m.
To three grades of noise barriers 38, comprise that the height of the whole noise barrier of elementary noise barrier 34, secondary noise barrier 36, three grades of noise barriers 38 can reach 3m by construction.Because three grades of noise barriers 38 are positioned at most end, therefore the 3rd reinforcing bar 37 is to be included in three grades of forms in noise barrier 38 completely.
The structure of the first movable mould (or movable mould) 100 to one embodiment of the present of invention describes below.Fig. 4 is the plan view of movable mould according to an embodiment of the invention.Figure is the rear elevation of movable mould according to an embodiment of the invention.Fig. 6 is the figure that illustrates the casting portion of the movable mould of Fig. 4.Fig. 7 illustrates the sectional view along A-A line of Fig. 4.
Referring to figs. 1 through Fig. 7, movable mould 100 comprises casting portion 110, front portion 120 and rear portion 130.
Anterior 120 one are connected to the front of casting portion 110.When the movable mould 100 being connected with concrete placer 2 moves, anterior 120 is the parts that contact with the first reinforcing bar 32 at first.Front portion 120 has according to the shape of elementary noise barrier 34 protrudes the front guide portion 121 of making.
From front guide portion 121 to rear guide portion 131, be formed with its cross section and there is the shape of elementary noise barrier 34 wide-open path.Therefore,, in the time that the movable mould 100 being connected with concrete placer 2 moves, when anterior 120 advance, after the first reinforcing bar 32 is guided by front guide portion 121, it is by rear guide portion 131.Now, concrete injects casting portion 110 and tamping, and afterwards again through rear guide portion 131 time, is completed into the shape with elementary noise barrier 34.
Concrete injects to the Part I 110a of casting portion 110.Due to partition board portion 115, the concrete that injects Part I 110a can directly not enter Part II 110b.Injecting the concrete of Part I 110a tamps by the vibration that is arranged on the vibrator (not shown) on the first vibrator installation portion 116 and the second vibrator installation portion 117, move to behind bottom simultaneously, enter Part II 110b by the lower space of partition board portion 115.Enter the concrete of Part II 110b by being arranged on the vibration of the vibrator (not shown) on the 3rd vibrator installation portion 118, be further compacted.
The first vibrator installation portion 116 is installed on partition board portion 115, and extends towards the central authorities of Part I 110a.The second vibrator installation portion 117 is installed on the metope of Part I 110a, and extends towards the central authorities of Part I 110a.The 3rd vibrator installation portion 118 is installed on the metope of Part II 110b.On the first vibrator installation portion 116, the second vibrator installation portion 117 and the 3rd vibrator installation portion 118, vibrator is installed, above-mentioned vibrator plays the effect that improves concrete density.
When there is no, in the situation of partition board portion 115, vibrator to be only arranged on the metope of casting portion 110.Because the lower width of elementary noise barrier 34 is more than 1m, therefore, by being arranged on the vibration of the vibrator on the metope of casting portion 110, be difficult to be delivered to the central authorities of casting portion 110, its result cannot fully be tamped concrete, causes the Quality Down of noise barrier.
In the present embodiment, be arranged on the first vibrator installation portion 116 in partition board portion 115 vibrator can be set, by the vibration of above-mentioned vibrator, can make the concrete that injects casting portion 110 can fully tamp on the whole.In addition, due to partition board portion 115, the concrete that injects Part I 110a can directly not enter Part II 110b, but after fully tamping by the vibration of vibrator, enter Part II 110b by the lower space of partition board portion 115, therefore can further improve concrete density.
In the time that movable mould 100 moves, should fully prevent the movement of reinforcing bar 11 (with reference to Fig. 7).For this reason, the reinforcing bar protection portion 140 that covers the upper end of reinforcing bar 11 and protect is set.Reinforcing bar protection portion 140 can be along laterally running through Part I 110a, and can along anterior 120 and rear portion 130 extend.Reinforcing bar protection portion 140 can be " ∩ " shape, protects to cover the upper end of reinforcing bar 11.In the time that movable mould 100 moves, when reinforcing bar protection portion 140 covers the upper end of reinforcing bar 11 and protects, prevent that reinforcing bar 11 is moved.
In addition, can guide rod 141 be set along laterally running through Part I 110a, to guide the both sides of reinforcing bar 11.Guide rod 141 is positioned at the below of reinforcing bar protection portion 140, when movable mould 100 is moved, prevents that reinforcing bar 11 is moved.Guide rod 141 also can extend along front portion 120 and rear portion 130.
With reference to Fig. 4, the open reinforcing bar guiding in the top identical with the width (w) of reinforcing bar protection portion 140 and unnecessary concrete removal portion 150 can be provided at rear portion 130, with can make the upper end of reinforcing bar 11 expose.
The top of reinforcing bar guiding and unnecessary concrete removal portion 150 is open, and therefore, when movable mould 100 is in the time moving to Part I 110a injection is concrete simultaneously, operator can collect the concrete that is positioned at reinforcing bar 11 upper ends by hand.If this is while being covered by concrete completely due to the upper end of reinforcing bar 11, while noise barrier being set by the method shown in Fig. 2 a to Fig. 2 f, the operation that is connected between the first reinforcing bar 32 and the second reinforcing bar 35 is difficult to carry out.As mentioned above, the object of reinforcing bar guiding and unnecessary concrete removal portion 150 is, while constructing elementary noise barrier 34, can collect the concrete that is positioned at reinforcing bar upper end by hand, thereby being connected between the first follow-up reinforcing bar 32 and the second reinforcing bar 35 can be carried out more easily.
For constructing second movable mould (not shown) of secondary noise barrier 36, and for the shape of the 3rd movable mould (not shown) of the three grades of noise barriers 38 of constructing, different from the shape of the first movable mould 100.Therefore, above-mentioned explanation is only applicable to the first movable mould 100, and is not suitable for the second movable mould and the 3rd movable mould.
