The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Slidably build a pre-buried composite member, comprise C type channel-section steel 1, the cross section of C type channel-section steel 1 is rectangle (as Fig. 1), the b middle part of a certain length of side that opening part is rectangle.The size of its opening a and channel-section steel plate thickness need according to requirements, by drawing after common mechanics load capacity calculation.For the less position of requirement for bearing capacity, the dimensions of C type channel-section steel 1 requires less, and opening requires also corresponding less; Otherwise contrary.On the external surface of C type channel-section steel 1, having a plurality of lug, nib 9(can be also a plurality of grooves), there is such structure, built-in fitting and concrete interlock are better, more stable after installation.
C type channel-section steel 1 opening part is provided with at least one bolt connection piece.For fear of C type channel-section steel 1, stop up notch when the pre-buried concrete, the inside of C type channel-section steel 1 is filled with granular polystyrene 2(as Fig. 1).In the present embodiment, bolt connection piece is one or surpasses one, and each bolt connection piece is comprised of bolt 2 and nut 5, and bolt forms (as shown in Figure 3) by head 31 and the screw rod 32 of bolt; The cross section of the head 31 of bolt is rectangle (being preferably the rectangle of chamfering) (as Fig. 2), and the long limit c of this rectangle is greater than the A/F a of C type channel-section steel 1, and meanwhile, the long limit c of rectangle is less than the side length b of the opening edge of C type channel-section steel 1; The minor face d of this rectangle is slightly larger than the A/F a of C type channel-section steel 1, when the minor face d of this rectangle tilts, the head of bolt 31 can be put into C type channel-section steel 1 and does not come off, and four jiaos, this rectangle arranges chamfering; Screw rod 32 is entire body screw thread, and diameter is slightly less than the A/F a of C type channel-section steel 1, can be in the interior any slip of C type channel-section steel 1.; The diameter of the screw rod of described bolt 3 is less than the A/F of C type channel-section steel 1.
The present embodiment is on the basis of above-mentioned any one embodiment, to increase following characteristics: a plurality of lug, nib 9(on the table of the outside of C type channel-section steel 1 can be also a plurality of grooves) bearing of trend all with the axially parallel (as Fig. 4) of C type channel-section steel 1, lug, nib and groove are so arranged, from mechanics angle analysis, stronger with concrete snap-in force, so the installation stability of built-in fitting is better.
The difference of the present embodiment and embodiment 1 is, the cross section of the C type channel-section steel 1 of this enforcement is trapezoidal.Opening part is the middle part (as shown in Figure 5) on trapezoidal arbitrary base (being preferably shorter base).The size of its opening a and channel-section steel plate thickness need according to requirements, by drawing after common mechanics load capacity calculation.
In the present embodiment, as shown in Figure 6,7, C type channel-section steel 1 cross section is designed to the trapezoidal C type channel-section steel 1 that can make and is embedded into after concrete, can be anchored at preferably in the concrete of sclerosis, while being subject to the pulling force of the weights such as equipment when composite member, the concrete of C type channel-section steel 1 both sides blocks C type channel-section steel 1, stops the trend of its relative sliding, thereby has strengthened the mechanics supporting capacity of pre-buried composite member.
Embodiment is on the basis of embodiment 3, increases following feature:
1, the cross section of C type channel-section steel 1 is isosceles trapezoid, and the acute angle that its base and hypotenuse form is 60 degree to 70 degree.
2 bolt connection pieces also comprise metallic gasket 4, and described metallic gasket 4 is socketed on the screw rod of bolt, and between the head and bolt of nut.This metallic gasket is perforated metal part, and its dimensions is with bolt head length of side c, d, and hole is positioned at pad central authorities, inner wall smooth.The size of hole is a bit larger tham the screw diameter of bolt, can be free to slide.
As shown in Figure 8,9, after having increased metallic gasket 4, the bolt connection piece that this enforcement is installed can be more stable, by the cross section of C type channel-section steel 1, be isosceles trapezoid simultaneously, the acute angle that its base and hypotenuse form is 60 degree to 70 degree, the selection of symmetrical structure and angle the experiment proved that like this, in the time of can making to be subject to the pulling force of the weights such as equipment when composite member, the strength that the concrete of C type channel-section steel 1 both sides blocks C type channel-section steel 1 is the strongest, stop the trend of its relative sliding also best, thereby greatly strengthened the mechanics supporting capacity of pre-buried composite member.
The present embodiment is on the basis of above-mentioned any embodiment once, to increase following technical characterictic:
The edge of the opening of C type channel-section steel 1 upwards forms and turns up part, and turn up part is obtuse angle alpha (as Figure 10) with the base formation angle of the opening of C type channel-section steel 1 simultaneously.In the present embodiment, because the opening of C type channel-section steel 1 is turned up part, therefore the width of bolt connection piece head is also wanted adaptive adjustment, bolt connection piece installs can be difficult a little, once but install, can more be not easy to come off, bolt connection piece slides and also can be more prone to simultaneously.
The pre-buried composite member of any one example of the present utility model through pre-buried C type channel-section steel 1 after reaching certain length of time in concrete, empty granular polystyrene 2 wherein, the head of bolt 3 31 is positioned in C type channel-section steel 1, after adjusting to the right place, fastening nut 5(is if any 4 cover upper metallic gaskets 4 of metallic gasket), assemble complete.The bolt foot extending out can be connected and fixed with weights such as equipment.
Although the utility model is described and specific explanations with reference to a plurality of embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification, combination or improvement to the composition structure of subject combination layout and/or layout.Except modification and the improvement carried out forming structure and/or layout, to those skilled in the art, other purposes will be also obvious.
