Embodiment

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the sectional view of the utility model pit structure, and Fig. 2 is connection machine shown in Fig. 1 The structural representation of structure.

The pit structure 1 is used to fix pit cushion cap 3 and connection hoistway frame 2, including located at the top of pit cushion cap 3 Bindiny mechanism 11 and in foundation ditch and the support pit cushion cap 3 fixed mechanism 13.

The fixed mechanism 13 includes being located on the side plate 131 of foundation pit side-wall, is covered in the bottom plate 132 of bottom of foundation ditch, erects Straight some first columns 133 being located on bottom plate 132, level are located at the supporting plate 134, second on the top of the first column 133 Column 135 and some support bars 136.

Some support bars 136 are located between the bottom plate 132 and the side plate 131.

Second column 135 is relative with first column 133 located at the bottom and position of the bottom plate 132, described First column 133 is through the bottom plate 132 and is inserted in inside second column 135.

It is that the supporting plate 134 is constituted for reinforced beam or with I-steel, H profile steel and with downward arc-shaped bend Steel structure girder.The pit cushion cap 3 is covered in the top of the supporting plate 134.

The supporting plate 134 is downward arc-shaped bend, thus only can be original downward in the pressure by axial direction Further bent on the basis of bending, without arbitrarily being bent to other directions so that the deformation direction of horizontal supporting plate 134 is able to Effective control.Then again by first column 133 do it is straight to support, make the supporting plate 134 by axial pressure There is reliable rigidity, it is to avoid it is further bent downwardly during power.

First column 133 and second column 135 are respectively steel structural upright column and concrete column.

In the present embodiment, the foundation ditch is square, and the bottom plate 132 is square steel plate, the number of the side plate 131 Measure as four, be respectively arranged on four sides of the bottom plate 132, first column 133 and second column 135 be four and The corner of the bottom plate 132 is respectively arranged on, the quantity of support bar 136 is eight, is respectively arranged on the two of four blocks of side plates 131 End.

The top of first column 133 includes regulation first 1331, and the regulation first 1331 is height fine adjusting function effect, specifically Can be spiral head or telescopic head.

The bindiny mechanism 11 includes foundation bolt 111, the steel plate 115 of anchor nut 113 and first, the foundation bolt 111 are plugged in the anchor nut 113 and the anchor nut 113 is embedded at the pit cushion cap 3, and the connecting rod 15 connects Connect first group 131 and the foundation bolt 111.

Further, the quantity of the foundation bolt 111, the anchor nut 113 and the connecting rod 15 is also four Root, four connecting rods 15 connect four first pile bodies 1311 and four foundation bolts 111 respectively.

First steel plate 115 is fixed in the top of the foundation bolt 111, and first steel plate 115 is formed with four the One mounting hole 1151；The hoistway frame 2 includes the second steel plate 21, and second steel plate 21 is formed with four the second mounting holes 211.

First steel plate 115 and second steel plate 21 are abutted and first mounting hole 1151 and described second is installed The position of hole 211 correspondence, the connecting bolt, which runs through, is located at first mounting hole 1151 and second mounting hole 211, passes through The mutual regulation of the foundation bolt 111 and anchor nut 113, is located at same level by first steel plate 115, reuses Connecting bolt is fixedly connected with the hoistway frame 2 and the bindiny mechanism 11.

2nd, the hoistway frame of the prior art and the bottom are replaced by the close bolt of the first steel plate and the second steel plate The framework of steel reinforcement of hole cushion cap is directly welded, and has both improved fixed stability and intensity, is reduced again and follow-up poured mixed mud and apply The stand-off error that work is caused, is conducive to the hoistway frame to be connected with accurate consolidate of the pit cushion cap.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical fields, are similarly included in scope of patent protection of the present utility model.
