The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one.
As shown in Figure 1, 2.
A kind of self-falling type anchorage of suspension cantilever beam laying end for construction, it buries two of being fixed in the concrete main body structure 6 and gives pipe laying 1 (can adopt plastic pipe), two bolts 2, a backing plate 3 and two fastening nuts 4 and form by giving, as shown in Figure 1.Bolt 2 is installed on to give in the pipe laying 1 and (can installs easily, dismounting), the lower end that described each bolt 2 passes concrete main body structure 6 is connected with load anticreep plate 7, load anticreep plate 7 can link to each other with bolt 2 welding or screw thread, the nut of also available increasing external diameter or BIG SIZE BOLTS head replace (at this moment, the lower end of bolt 2 and load anticreep plate 7 are actually an overall structure), in order to guarantee that ground tackle can bear enough pulling force, the area of load anticreep plate 7 should be big as far as possible, it should be described 4 times of giving pipe laying 1 sectional area at least in theory, an end that is positioned at concrete main body structure 6 of each bolt 2 passes backing plate 3 and fastening nut 4 is installed, preferably install pad additional between fastening nut 4 and backing plate 3, the beam 5 of encorbelmenting is positioned between the upper surface of described backing plate 3 and concrete main body structure 6.In order to satisfy the encorbelment needs of beam width of difference, and the consumption of minimizing backing plate 3, can respectively be provided with the strip roll adjustment groove 10 that a width and bolt 2 external diameters match at the two ends of backing plate 3, as shown in Figure 2, two roll adjustment grooves 10 also can connect into one and be similar to groove shown in Figure 5.
During concrete the use, each beam of encorbelmenting preferably uses two ground tackles of the present utility model.Load anticreep plate can be pre-buried together when floor is poured into a mould with giving pipe laying 1, at this moment, should add coating release agent on load anticreep plate 7 and one side that floor contacts.Also can after finishing, the floor cast install again.
The using method of present embodiment is:
Can directly backing plate 3 be enclosed within on the bolt 2 for giving when burying at load anticreep plate 7, screw on fastening nut 4, mention backing plate 3, an end of the beam 5 of will encorbelmenting then inserts the bottom of backing plate 3, with spanner fastening nut 4 is tightened to get final product.During dismounting, unclamp firm nut 4 earlier, extract the beam of encorbelmenting out, knock bolt 2 downwards bolt 2 is separated with floor, can use next time after the collection.
, at first bolt 2 should be passed from the bottom of floor and give pipe laying 1 during at load anticreep plate 7 for pre-embedded type structure not, and then cover upper padding plate 3, screw on fastening nut 4, insert an end of the beam of encorbelmenting, tighten fastening nut 4 and get final product.Dismounting is with preceding identical.
Embodiment two.
Shown in Fig. 3,4,5,2.
A kind of self-falling type anchorage of suspension cantilever beam laying end for construction, it buries two of being fixed in the concrete main body structure 6 and gives pipe laying 1 by giving, two bolts 2, a backing plate 3, two fastening nuts 4 and a lower bolster 8 are formed, as shown in Figure 3, bolt 2 is installed on to give in the pipe laying 1 and can move up and down and (can be tight fit, also can be loose fit), backing plate 3 and lower bolster 8 lay respectively at the upper and lower surface of concrete main body structure 6, the beam 5 of encorbelmenting is positioned between the upper surface of backing plate 3 and concrete main body structure 6, lower bolster 3 is all passed in the lower end of two bolts 2, load anticreep plate or anticreep nut 9 are installed on it, tightening nut 4 is installed on the end that bolt 2 passes backing plate 3, can install elastomeric pad additional between firm nut 4 and backing plate 3.Equally for the width of the beam of encorbelmenting that adapts to different size, on backing plate 3, be provided with the strip roll adjustment groove 10 that or two width and bolt 2 external diameters match, be similar to shown in Fig. 2,5, the external diameter of its width and bolt 2 is quite or bigger getting final product.Same in order to be applicable to the different beams of encorbelmenting, on lower bolster 8, be provided with the strip roll adjustment groove 11 that or two width and bolt 2 external diameters match, shown in Fig. 3,4.Equally, be used for the load anticreep plate that offsets with lower bolster 8 or anticreep nut 9 also can be directly and bolt 2 lower ends be weldingly connected, or link to each other by screw thread.When using the structure of present embodiment, the size of load anticreep plate or anticreep nut 9 can be smaller, because at this moment, the major part of the pulling force of the beam of encorbelmenting is born by lower bolster 8, the load anticreep plate 7 of embodiment one then need directly bears the pulling force of the beam of encorbelmenting.
During concrete enforcement, lower bolster 8 also can give on the soffit that is embedded in floor (being concrete main body structure 6) as the load anticreep plate 7 of embodiment one, and at its external coating release agent, so that dismounting.
The using method of present embodiment and embodiment one are identical.
By the encorbelment fixed form of beam of change, the problem of management of utilizing simple load and unload screw connection structure to solve installation, construction and the machine equipment of construction site is main points of the present utility model.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
