Embodiment 2
The utility model embodiment 2 provides a kind of Cantilever Beams fastening devices for building, this Cantilever Beams fastening devices for building comprises all technical characteristic of the Cantilever Beams fastening devices for building that embodiment 1 provides, and the Cantilever Beams fastening devices for building that embodiment 2 provides also comprises following technical characteristic:
The structural representation of the Cantilever Beams fastening devices for building that Fig. 2 provides for the utility model embodiment 2; The side-looking structural representation of the Cantilever Beams fastening devices for building that Fig. 3 provides for the utility model embodiment 2; Refer to Fig. 2 and Fig. 3, stressed plate 201 is respectively arranged with ear 203 in the both sides of side 102, and screwed hole is arranged in ear 203.
Ear 203 is set respectively by the both sides at side 102, and screwed hole is set in Liang Ge ear 203, make ear 203 can bear the fastening force of lock bolt 202, and by arranging ear 203, be convenient to arrange multiple screwed hole in ear 203.
Stressed plate 201 is circular or square, and the part that ear 203 protrudes from side 102 by the both sides of stressed plate 201 is formed.Refer to Fig. 3, in the present embodiment, diagram merely illustrates square stressed plate 201.
Circular or square by stressed plate 201 is set to, increase the area of stressed plate 201, and form semicircle or square ear 203, be convenient to arrange screwed hole, make ear 203 can bear the fastening force of lock bolt 202 well.
The structural representation of the reinforcing rib 204 of the Cantilever Beams fastening devices for building that Fig. 4 provides for the utility model embodiment 2; Refer to Fig. 2 ~ Fig. 4, stressed plate 201 is provided with reinforcing rib 204 near the side of Cantilever Beams 301, and reinforcing rib 204 is connected with side 102.
When inwardly tightening lock bolt 202, because ear 203 protrudes from side 102, the fastening force of lock bolt 202 may make ear 203 inwardly deviation, produce deformation, after ear 203 deviation, lock bolt 202 cannot vertically act on Cantilever Beams 301, can not carry out the fixing of side direction well, and be unfavorable for reusing for a long time to Cantilever Beams 301.By arranging reinforcing rib 204, the fastening force reducing lock bolt 202, on the impact of ear 203, is avoided producing inside deviation and causing side direction fixed effect poor.
Screwed hole is four, is relatively arranged in ear 203 between two, and the quantity of lock bolt 202 is correspondingly four.By screwed hole is set to four, and be relatively arranged between two in ear 203, make same group of relative lock bolt 202 after locking, be in corresponding position, Cantilever Beams 301 both sides, effectively prevent moving left and right of Cantilever Beams 301, fixing effect can be played well.
Certainly, the quantity of lock bolt 202 is not limited to four, can be one, two, three or multiple, only Cantilever Beams 301 side direction can be fixed.
Refer to Fig. 2, top margin 101 is straight flange or arc-shaped side.By top margin 101 is set to straight flange or arc-shaped side, make top margin 101 can prop up the top of Cantilever Beams 301.What in the present embodiment, top margin 101 adopted is arc-shaped side, and top margin and two sides form U-shaped, as long as top margin 101 can prop up the top of Cantilever Beams 301.
Side 102 cover has PVC sleeve pipe, and the size of PVC sleeve pipe 105 is slightly larger than the size of side 102.During installation, by PVC sleeve pipe 105 embedded structure floor 401, side 102 passes from PVC sleeve pipe 105, by side 102 is passed PVC sleeve pipe 105, decreases the impact on structure floor 401.
Backing plate 106 is provided with between base plate 103 and structure floor 401.It is fixing more firm to make.Backing plate 106 can be cushion, such as rubber pad; Also can be metal sheet, such as steel plate.And the effect of cushion is better.
Embodiment 3
The utility model embodiment 3 provides a kind of Cantilever Beams fastening devices for building, and the difference of the Cantilever Beams fastening devices for building that this Cantilever Beams fastening devices for building and embodiment 2 provide only is also to be provided with force transmission element 205 between the stressed plate 201 of the Cantilever Beams fastening devices for building that embodiment 3 provides and Cantilever Beams 301.
The structural representation of the Cantilever Beams fastening devices for building that Fig. 5 provides for the utility model embodiment 3, refers to Fig. 5, is provided with force transmission element 205 between stressed plate 201 and Cantilever Beams 301.
Because Cantilever Beams 301 is generally i iron, its sunk part is general comparatively dark, directly adopts lock bolt 202 to carry out locking, the lock bolt 202 needing length longer, uses longer lock bolt 202 after passing stressed plate 201, its direction is difficult to control, and is easy to offset.
By arranging force transmission element 205, namely shorter lock bolt 202 is used, only need lock bolt 202 through stressed plate 201, then act on force transmission element 205, by force transmission element 205, fastening force is passed to the recess of Cantilever Beams 301, can ensure that side direction is fixed, avoid again using longer lock bolt 202.
Force transmission element 205 is elastomeric element.Force transmission element 205 adopts elastomeric element, such as rubber pad, cushioning effect can be played, and the friction factor between elastomeric element and Cantilever Beams 301 is larger, prevent lock bolt 202 by force transmission element 205 act on Cantilever Beams 301 is fixed time, there is Relative sliding between force transmission element 205 and Cantilever Beams 301, make the side direction of Cantilever Beams 301 fixing more firm.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
