The specific embodiment

For the benefit of the understanding to structure of the present utility model, describes below in conjunction with drawings and Examples.

With reference to Fig. 1, be the sectional structure schematic diagram of the utility model tower-crane foundation structure, as shown in Figure 1, the utility model provides a kind of tower-crane foundation structure, comprising: the formed concrete foundation 1 of once grouting; Be fixed on the many spacer barss 2 in concrete foundation 1; Be arranged at the sole plate 3 at spacer bars 2 tops; And be arranged at the cushion cap 6 on sole plate 3.

In the present embodiment, the utility model tower-crane foundation structure can be constructed according to the following steps, comprises following main process:

A. planting reinforced bar into concrete process

Can be with reference to Fig. 2, for the utility model spacer bars 2 is anchored in the cross-sectional schematic of concrete foundation 1, as shown in Figure 2, during construction, should first carry out: need, in advance according to the load needs of tower crane, calculate cross section, quantity and the anchorage depth thereof of required spacer bars 2.After to be calculated completing, just can be in the concrete foundation 1 of once grouting moulding, (reinforced hole also can be arranged by other rule forms certainly, for example to offer a plurality of reinforced holes of arranging with matrix form, rice font is arranged), the degree of depth of reinforced hole need reach the calculating setting value of anchorage depth.Then, by construction requirement, many spacer barss 2 are implanted in respectively in each reinforced hole, when reinforcing bar 2 to be positioned arrives the anchorage depth of reinforced hole, anchor and position reinforcing bar 2 makes it naturally protrude and be revealed on concrete foundation 1.Mode according to this, forms the bar planting region 8 of a rectangle.

It should be noted that because existing tower crane generally has four lower margins, therefore, with reference to Fig. 3, is the plan structure schematic diagram in four bar planting regions 8 of the utility model formation, as shown in Figure 3, repeats said process, forms four bar planting regions all around.

B. the position fixing process of sole plate 3

Can be with reference to Fig. 4, for the plan structure schematic diagram of the utility model sole plate 3, shown in Fig. 3 and Fig. 4, for each bar planting region 8, prepare in advance a block plate as sole plate 3, on this sole plate 3, need to offer can be corresponding with spacer bars 2 a plurality of locating holes 30.When implementing, can lip block be set in sole plate 3 soffit surroundings, so that sole plate 3 is supported every sky temporarily, and guarantee that each locating hole 30 is interior to there being a spacer bars 2, realize locating every sky of sole plate 3.

C. the levelling process of sole plate 3

Can be with reference to Fig. 5, sectional structure schematic diagram for the utility model immobilizing foundation base plate 3 on the basis of Fig. 3 and Fig. 4, as shown in Figure 5, for each bar planting region 8, because sole plate 3 is supported every sky temporarily, thereby self-assembling formation is every absolutely empty 4 between sole plate 3 and concrete foundation 1, whereby, can carry out to sole plate 3 accurate adjustment of levelness.Particularly, when implementing, can utilize level gauge that sole plate 3 is constantly carried out the detection of levelness and adjusted in real time, until all sole plates 3 in four bar planting regions 8 of base are all in same preset height, realize the levelling of sole plate 3 degree of precision.

D. the fixation procedure of sole plate 3

Can be with reference to Fig. 6, for the utility model is filled grouting to form the sectional structure schematic diagram of leveling layer 5 on the basis of Fig. 5, as shown in Figure 5, for each bar planting region 8, after the levelness of sole plate 3 reaches construction precision and requires, ideal situation is, the upper surface of sole plate 3 flushes with the top of spacer bars 2, now, just can first locating hole 30 and the welded top of spacer bars 2 be fixed up, again the cushion block that is supported in sole plate 3 soffit surroundings is removed, afterwards, just can every absolutely empty 4, carry out back-grouting to formed, filling and enrich every absolutely empty 4.Afterwards, between sole plate 3 and concrete foundation 1, just formed one deck leveling layer 5, with this, stable degree of sole plate 3 has been improved significantly

E. the assignment procedure of cushion cap 6

Can be with reference to Fig. 7, sectional structure schematic diagram for the utility model fixed bearing platform 6 on Fig. 6 basis, as shown in Figure 7, for each bar planting region 8, after leveling layer 5 thoroughly solidifies, just can be on sole plate 3 fixed bearing platform 6, comparatively ideally, cushion cap 6 is fixedly welded on the center of sole plate 3.

F. the assignment procedure of tower crane anchor 7

Can be with reference to Fig. 7 and Fig. 8, Fig. 7 is the plan structure schematic diagram of the utility model cushion cap 6 end faces, Fig. 8 is the utility model fixing sectional structure schematic diagram of tower crane anchor 7 on Fig. 6 and Fig. 7 basis, shown in Fig. 7 and Fig. 8, for each bar planting region 8, because the upper surface of each cushion cap 6 all has locating wheel profile 60, after cushion cap 6 is welded and fixed, tower crane anchor 7 need come by these locating wheel profiles 60 of cushion cap 6 upper surfaces the as far as possible accurately relative permanent position of tower crane anchor 7 and cushion cap 6.

In the present embodiment, concrete foundation 1 is formed in the pit excavating on ground, job site; Can select round bar as spacer bars 2, until all spacer barss 2, be fixed on after concrete foundation 1, need to form four bar planting regions 8 as shown in Figure 3, and each bar planting region 8 is interior all has the included said structure feature of the utility model tower-crane foundation structure as shown in Figure 1; Select square plate as sole plate 3, for corresponding to round bar, offer circular locating hole 30 on sole plate 3, spacer bars 2 is arranged and is welded to connect with the equal matrix of locating hole 30; And, between sole plate 3 and concrete foundation 1, through back-grouting, to fill, be formed with one deck leveling layer 5; The cushion cap 6 of ladder type is fixedly welded on the upper surface center of sole plate 3, and the upper surface of cushion cap 6 is laid with many locating wheel profiles 60, is accurately fixed on the upper surface of cushion cap 6 for tower crane anchor 7.
