The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be described further:
Three lattices that Fig. 1 provides for patent working example of the present invention combine the front view of tower-crane foundation structures.
Three lattices that Fig. 2 provides for patent working example of the present invention combine the top view of tower-crane foundation structures.
Three lattices that Fig. 3 provides for patent working example of the present invention combine the syndeton schematic diagram between bridging, connecting rod, backing plate and laced of battened compression member in tower-crane foundation structures.
Three lattices that Fig. 4 provides for patent working example of the present invention combine the structural representation of tower-crane foundation structure junction plates.
Wherein: 1-concrete bearing platform, 2-laced of battened compression member, 3-bridging, 4-connecting rod, 5-castinplace pile, 6-anchor bar, 7-junction plate, 8-backing plate, 9-tower crane anchor pin, 10-support angle steel.
The specific embodiment
Shown in Fig. 1, disclosed this three lattices combination tower-crane foundation structure of the present embodiment, comprise three castinplace piles of vertically arranging 5, three laced of battened compression member 2 of vertically arranging and concrete bearing platforms 1 that are positioned at described laced of battened compression member top.Wherein, three castinplace pile 5 distributions triangular in shape not on same straight line, concrete bearing platform 1 is roughly triangular in shape, and in concrete bearing platform 1, anchor is provided with several tower crane anchor pin 9 protruded upward, for fixing tower crane.
The lower end of described three laced of battened compression member 2 anchors into respectively in described three castinplace piles 5, the upper end of described three laced of battened compression member 2 all anchors in described concrete bearing platform 1, and all is fixedly installed the bridging 3 of some vertical layouts and the connecting rod 4 of some horizontal arrangement between any two laced of battened compression member 2.In the present embodiment, described bridging 3 and the connecting rod 4 concrete assembling mode on laced of battened compression member 2 can be with reference to shown in Fig. 1 and Fig. 3: be welded with a plurality of junction plates 7 on laced of battened compression member 2, described bridging 3 is weldingly fixed on described junction plate 7; Also be welded with backing plate 8 on described junction plate 7, described connecting rod 4 is weldingly fixed on described backing plate 8.Be that bridging 3 and connecting rod 4 are not directly to be welded on laced of battened compression member 2, but be fixed by junction plate 7 and backing plate 8, this be because: three laced of battened compression member 2 are triangularly arranged, and laced of battened compression member 2 cross sections are rectangular, the whole shape that forms triangular prism of three laced of battened compression member 2 be triangularly arranged, and this triangular prism has at least two vertical sides not to be on same vertical plane with the side of laced of battened compression member 2 self, if bridging 3 and connecting rod 4 directly are welded on two laced of battened compression member 2, to cause part bridging 3, the solder side that connecting rod 4 and laced of battened compression member are 2 is too small, and affect the structural stability on this tower crane basis, and by after junction plate 7, can will after part junction plate 7 bending certain angles, with laced of battened compression member 2, be welded and fixed again, thereby make the vertical side of triangular prism and the junction plate 7 in the same vertical plane, thereby guaranteed the bonding area of 7 of bridging 3, connecting rod 4 and junction plates, as Fig. 4.
In order to strengthen the bonding strength of described laced of battened compression member 2 and concrete bearing platform 1, this example is welded with anchor bar 6 in the upper end of laced of battened compression member 2, and described anchor bar 6 integral body anchor in described concrete bearing platform 1.
In order to strengthen the supporting force of 2 pairs of concrete bearing platforms 1 of described laced of battened compression member, this example also is welded with the support angle steel 10 of being close to concrete bearing platform 1 bottom on laced of battened compression member 2.
As shown in Figure 2, in the present embodiment, it is symmetrical that described three castinplace piles 5 are equilateral triangle, and these three castinplace piles 5 are arranged on three summits of equilateral triangle.Described tower crane anchor pin 9 is provided with four altogether, and these four tower crane anchor pin 9 are square symmetry and distribute, and these three tower crane anchor pin 9 are arranged on foursquare four summits.And the center of gravity of the symmetrical centre of described four tower crane anchor pin 9, the symmetrical centre of described three laced of battened compression member 2 and described concrete bearing platform 1 is on same vertical curve, to guarantee the stability of this tower-crane foundation structure of the present embodiment.
Shown in Fig. 1~Fig. 4, it is now that the job practices brief introduction of this tower-crane foundation structure of the present embodiment is as follows: after three castinplace piles 5 and laced of battened compression member 2 have been constructed, after castinplace pile 5 pile body concrete reach design strength, unloading cubic metre of earth, welding support angle steel 10 and anchor bar 6 on laced of battened compression member 2, the reinforcing bar of colligation concrete bearing platform 1 subsequently, lay tower crane anchor pin 9, concreting, after the cushion cap concrete strength meets the demands, tower crane is installed, stage excavation along with pit earthwork, be welded and fixed junction plate 7 and backing plate 8 on laced of battened compression member 2, then be welded and fixed vertical bridging 3 on junction plate 7, be welded and fixed waling stripe 4 on backing plate 8, successively three laced of battened compression member 2 are connected to integral body, until finish the foundation ditch bottom.
Certainly, above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow people can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformation or modification that according to the present invention, the Spirit Essence of main technical schemes is done, within all should being encompassed in protection scope of the present invention.
