The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, not do under the situation of opposite explanation, the noun of locality of use mainly is to be directed against the direction shown in the view; For example, the left and right directions shown in Fig. 2 is the length direction of screed, and above-below direction is the short transverse of screed; In addition; Two ends near length direction are referred to as " outward ", otherwise, then be referred to as " interior " near the center of length direction.
Screed all is the bilateral symmetry structure usually, therefore, mainly is that the situation with screed one side is that example describes below.But what need particularly point out is, the screed of symmetry fully about the utility model is not limited to, as long as any side of screed has comprised the content of the utility model, it should drop within the protection domain of the utility model equally.
Also need to prove in addition; The utility model is than prior art, and its main improvements are to support pull bar, therefore; Other aspects for screed; Under the situation that the utility model does not specify, can adopt prior art, this should be to understand easily and enforcement to those skilled in the art.
Fig. 2 has shown the screed according to a kind of embodiment of the utility model.As shown in Figure 2; This screed comprises basic screed 10 and a plurality of lengthening screeds 20 that are positioned at these basic screed 10 1 sides; Length direction along said screed is provided with a plurality of support pull bars 30; Adjacent two support pull bars 30 are hinged to the upper end of a bracing frame 40, and the lower end of this bracing frame 40 is hinged on one of them lengthening screed 20.
As a kind of concrete embodiment, shown among Fig. 2 that a side of basic screed 10 has the situation of four lengthening screeds 20.For the ease of describing; Can be referred to as first to fourth lengthening screed from inside to outside successively; Between basic screed 10 and the 3rd lengthening screed, have two support pull bars 30; These two support pull bars 30 are hinged to the upper end of a bracing frame 40, and the lower end of this bracing frame 40 then is hinged to the outboard end of first lengthening screed 20.The support pull bar of the inboard in two support pull bars 30 is connected between basic screed and the bracing frame, and the support pull bar in the outside is connected between bracing frame and the lengthening screed.
Obviously, shown in Fig. 2 only is an embodiment of the utility model, and according to actual conditions, the number of lengthening screed 20 can be less than four, also can be more than four.In like manner, on the length direction of screed, the number of support pull bar 30 can be 3 even more a plurality of, then uses a bracing frame 40 to link to each other between every adjacent two support pull bars 30.
Than prior art, owing to connect two support pull bars 30 through a bracing frame 40, therefore the length of single support pull bar 30 can shorten greatly, therefore installs and regulate all becoming very convenient.In addition, can clearly be seen that from Fig. 2 that owing to the middle bracing frame 40 that adopts supports, therefore, the support pull bar 30 in the outside and the increase of the angle a between the screed for example generally can be spent 15～25, thereby can significantly improve the integral rigidity of screed.
Preferably, the lower end of bracing frame 40 is hinged to the outside portion of corresponding lengthening screed 20.Because each lengthening screed generally is the body structure of sealing, simultaneously, lengthening screed 20 generally is stitched together through the mode of mechanical connection each other.Therefore, the outside portion intensity of lengthening screed is compared other positions and is wanted big.Therefore, based on the consideration of space layout and bonding strength requirement, preferably bracing frame is connected to the outside portion of lengthening screed.
As shown in Figure 2, as another preferred embodiment, the lower end of bracing frame 40 can also be connected to basic screed 10 through an auxiliary support pull bar 30 '.This mode can promote the integral rigidity of screed mid portion, strengthens the whole structural stability of screed.
Particularly; The outside of screed 10 generally has upwardly extending boss 11 and is formed at the ear seat 12 on this boss 11, and the medial extremity of the most inboard support pull bar 30 in said a plurality of support pull bars and the medial extremity of said auxiliary support pull bar 30 ' can be hinged on this ear seat 12.This arrangement is simple and reasonable for structure.
Fig. 3 has shown the screed according to the another kind of embodiment of the utility model.
As shown in Figure 3, in a side of basic screed 10, have six lengthening screeds 20, correspondingly, between basic screed and lengthening screed, have three support pull bars 30 and two bracing frames 40.the most inboard support pull bar in three support pull bars 30 is connected between basic screed and the inboard bracing frame, and outermost support pull bar is connected between the bracing frame and lengthening screed in the outside, and middle support pull bar is connected between two bracing frames.In addition, also be connected with an other auxiliary support pull bar 30 ' between the lower end of the upper end of the medial branch support in two bracing frames and lateral branch support.Other aspects of this embodiment can be with reference to first kind of above-mentioned embodiment, and the utility model repeats no more to this.
Fig. 4 has shown the sketch map of the bracing frame of a kind of embodiment of the utility model.Fig. 5 is the left view of Fig. 4.
Like Fig. 4 and shown in Figure 5; The lower end of bracing frame 40 has following hinge hole 41; The inside and outside both sides of upper end have interior hinge hole 42 and outer hinge hole 43 respectively; Adjacent two support pull bars 30 can be hinged on the support frame as described above 40 through the bearing pin that passes said interior hinge hole 42 and outer hinge hole 43 respectively, and 40 of this bracing frames can be hinged on the corresponding lengthening screed through passing the said bearing pin of hinge hole 41 down.
The utility model also requires to protect a kind of paver, and this paver comprises above-mentioned any one screed that the utility model provides.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
