DETAILED DESCRIPTION

[0022] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples or drawings are used to illustrate the utility model, but not to limit the scope of the utility model.

[0023] A flexible support pile head anti-settling device, as shown in Figures 1 to 5 Fig. 1, comprises a pile foundation top plate 1, a pile head connecting plate 2, a stabilizing shaft sleeve 3, a stabilizing shaft 4, and an upper top plate 5. The pile foundation top plate 1 is installed on the pile foundation. The pile head connecting plate 2 is installed on the pile foundation top plate 1. The upper top plate 5 is located above the pile head connecting plate 2 and is used to support the cross beam 10. The stabilizing shaft sleeve 3 is located between the pile head connecting plate 2 and the upper top plate 5, and the stabilizing shaft sleeve 3 is fixed on the pile head connecting plate 2. The stabilizing shaft 4 is fixedly installed on the upper top plate 5, and the lower end of the stabilizing shaft 4 extends into the stabilizing shaft sleeve 3.

[0024] The lower end of the upper top plate 5 is provided with two positioning clamps 6, which are symmetrically distributed on both sides of the stabilizing shaft sleeve 3. Two stabilizing clamps 7 are placed inside the positioning clamps 6. A support clamp 8 is placed inside the stabilizing clamp 7. The spring device 9 is arranged between the support clamp 8 and the stabilizing shaft sleeve 3. The positioning clamps 6, the stabilizing clamps 7, and the support clamps 8 are closely arranged between the pile head connecting plate 2 and the upper top plate 5.

[0025] When the pile foundation initially appears a settlement phenomenon, the stabilizing shaft sleeve 3, the stabilizing clamps 7, and the support clamps 8 sink together with the pile head connecting plate 2 connected with the pile foundation. The stabilizing shaft 4 and the positioning clamps 6 remain at the initial height because the upper top plate 5 connected with the cross beam 10. The spring device 9 increases the friction force between the two stabilizing clamps 7 and between the stabilizing clamp 7 and the support clamp 8, so that the relative positional relationship between the stabilizing clamps 7 and the support clamps 8 remains unchanged, showing a movement state that the stabilizing clamps 7 and the support clamps 8 move downward relative to the positioning clamps 6. With the settlement phenomenon of the pile foundation, the stabilizing clamps 7 and the positioning clamps 6 are clamped, the two adjacent stabilizing clamps 7 are clamped with each other, and the support clamps 8 and the stabilizing clamps 7 are clamped in turn. At different settlement depths, the cross beam 10 load is supported, and the upward force caused by wind suction can also be resisted, avoiding the occurrence of large internal force changes of the top cross beam 10 due to the settlement phenomenon, thereby preventing the deformation of the cross beam 10. It can allow a certain range of pile foundation settlement phenomenon, achieve the function of protecting the structure stability of the cross beam 10;

[0027] As Figure 4 shown, the lower end of the stabilizing shaft 4 is provided with a clamping block 16 which is inside the stabilizing shaft sleeve 3.

[0028] When the pile foundation has a certain amount of first stage settlement, the stabilizing clamp 7 which is close to the positioning clamp 6 is preset to be the outer stabilizing clamp 7, the clamping block 15 on the outer stabilizing clamp 7 is lowered to the same height as the clamping groove 14 on the positioning clamp 6, under the action of the spring device 9, the clamping block 15 and the clamping groove 14 are clamped, the relative position relationship between the outer stabilizing clamp 7 and the positioning clamp 6 is fixed, at this time, the outer stabilizing clamp 7 cooperates with the positioning clamp 6 to support the load of the top beam 10;

[0029] Similarly, when the pile foundation has a certain amount of second stage settlement again, the inner stabilizing clamp 7 is lowered relative to the outer stabilizing clamp 7, the clamping block 15 on the inner stabilizing clamp 7 is clamped with the clamping groove 14 on the outer stabilizing clamp 7, the inner stabilizing clamp 7 can also support the load of the top beam 10;

[0030] Similarly, when the pile foundation has a certain amount of third stage settlement for the third time, the supporting clamp 8 is lowered relative to the inner stabilizing clamp 7, the clamping block 15 on the supporting clamp 8 is clamped with the clamping groove 14 on the inner stabilizing clamp 7, the supporting clamp 8 can also support the load of the top beam 10; for different stages of settlement, when the wind suction condition, the upward force of the beam 10 can be tightened by the nut at the upper end of the stabilizing shaft 4, so that the stabilizing shaft 4 inside the stabilizing shaft sleeve 3 and the clamping block 16 are lifted and closely fit with the inner measurement of the upper part of the stabilizing shaft sleeve 4, to resist the wind suction force.

[0031] After the above three settlements, the stabilizing shaft 4 reaches the top end of the inner wall of the stabilizing shaft sleeve 3, the relative sliding distance between the stabilizing shaft sleeve 3 and the stabilizing shaft 4 reaches the maximum value, the stabilizing shaft 4 and the stabilizing shaft sleeve 3 are clamped and fixed, preventing the upper structure of the pile head from moving up, thereby ensuring the stability of the pile foundation within a certain range of sinking without affecting the structure of the upper beam 10, and ensuring the stability of the upper beam 10.

[0032] The pile head connecting plate 2 is fixed on the pile foundation top plate 1 by fasteners, the pile foundation top plate 1 is fixed on the pile foundation by fasteners, the stabilizing shaft sleeve 3 is fixed on the pile head connecting plate 2 in a threaded connection manner, and the stabilizing shaft 4 is fixedly connected with the upper top plate 5 by threaded fasteners.

[0033] The positioning clamping piece 6 is fixed on the upper top plate 5 in a welding manner, and the lower end of the positioning clamping piece 6 is in abutment with the upper end of the pile head connecting plate 2 in an initial state.

[0034] Two corner codes 12 are arranged on the upper end of the upper top plate 5, and a cross beam transition plate 11 is welded on the side of the cross beam 10, and the cross beam transition plate 11 is connected with the corner code 12 through a bolt fastener 13.
