In above-mentioned steps (b), by successively U-shaped clamping type connector being inserted in the first steel bushing on adjacent two panels steel form flange, adjacent two panels punching block board load is connect, four steel forms is enclosed and is assembled into square conical cushion cap wide at the top and narrow at the bottom; In above-mentioned steps (c), the crotch at support member two ends is inserted in the second steel bushing that on steel form, base is middle, bracing reinforcement cushion cap.
The pile foundation support table periphery facade bed course tool-type punching block of the present invention have employed batch production, the thinking of recycling, and steel form adopts and makes and reusable according to pile cap shape size burst. Steel form processing and fabricating and assembling are simple, and structure stress is reasonable. On steel form, welded reinforcement is put more energy into muscle, makes steel template structure reasonable stress, simple for production, saves material. The flange of steel form side is easy to U-shaped clamping type connector by adjacent two panels steel form clamping, makes the tight not spillage of splicing seam. Adopt the pile foundation support table periphery facade bed course that steel form makes to have compared with brick tyre mould making operation is simple, material therefor kind is single, can the advantage such as one-shot forming, construction cost can be substantially reduced, improve speed of application and finished product concrete quality. The present invention is that pile foundation support table periphery cushion construction provides a kind of simple and practical construction tool and construction method.

Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, pile foundation support table periphery facade bed course tool-type punching block includes and is enclosed in the square conical wide at the top and narrow at the bottom of pile foundation 4 periphery, the support member 2 being respectively supported between the trapezoidal steel form of relative two panels 1 by four trapezoidal steel forms 1, connects the U-shaped clamping type connector 3 of adjacent two panels steel form. The side of steel form is with the flange 1a outwards dug, and U-shaped clamping type connector 3 is installed on the flange of adjacent two panels steel form, by adjacent two panels steel form against connection. Steel form is provided with ribs 1d. Ribs 1d adopt reinforcement welding steel form periphery, on centre position between base and bottom, diagonal positions, to increase the rigidity of steel form so that it is be unlikely to deform in cushion cap periphery facade blinding concrete casting process, it is ensured that pouring quality. Being respectively welded the steel bushing assembly for punching block at steel form along two side flanging upper-lower positions, U-shaped clamping type connector 3 inserts in the first steel bushing 1b of adjacent two panels punching block, adjacent two panels punching block version is connected. Support member 2 is the two ends steel ribs with crotch 2a, on every steel form, the second steel bushing 1c is welded in centre position, base, the crotch 2a at support member 2 two ends inserts in the second steel bushing of relative two pieces of steel forms respectively, is supported reinforcing from steel form point midway suitable for reading to tool-type punching block. Steel form adopts Q235 steel plate to make, steel plate thickness 2.5mm.Steel form size makes according to pile foundation support table size, and each piece of punching block is shaped as wide at the top and narrow at the bottom trapezoidal, the side flange width 30mm of steel form, with steel plain be 90 �� vertical. The reinforcement fabrication of U-shaped clamping type connector diameter 25mm. Support member 2 is also adopted by the reinforcement fabrication of diameter 25mm.
The construction of pile foundation support table periphery facade bed course tool-type punching block of the present invention adopts the construction method of on-site consolidation, specifically comprises the following steps that
(a) unwrapping wire: longitudinally put cushion cap periphery center line, i.e. the location line of pile foundation support table periphery bed course tool-type punching block on the raft plate cushion layer structure face need mounting tool type punching block with axis of pitch respectively;
B () installs pile foundation support table periphery facade bed course tool-type punching block: in cushion cap foundation ditch, adjacent two panels punching block board load connect with U-shaped clamping type connector 3 successively, four steel forms 1 are enclosed and is assembled into square conical cushion cap wide at the top and narrow at the bottom; Next adjust the vertical position of punching block with level gauge, if punching block vertical position has deviation, then adjust its vertical position with cushion blocks such as flitches; Punching block position adjustment is pushed against in pile crown with flitch etc. after completing, it is ensured that in concreting process, punching block does not misplace;
C () installs support member: connect with the center line of engineering bundle of lines cushion cap periphery and fix successively, midpoint suitable for reading for tool-type punching block is overlapped with engineering line, fix the position of punching block, support member 2 is respectively mounted and is supported between the trapezoidal steel form 1 of relative two panels.
In above-mentioned steps (b), by successively U-shaped clamping type connector 3 being inserted in the first steel bushing 1b on adjacent two panels steel form flange, adjacent two panels punching block board load is connect, four steel forms 1 is enclosed and is assembled into square conical cushion cap wide at the top and narrow at the bottom; In above-mentioned steps (c), the crotch 2a at support member 2 two ends is inserted in the second steel bushing 1c that on steel form, base is middle, bracing reinforcement cushion cap.
The present invention, through Practical Project verification experimental verification, can make the engineering project raft foundation bearing platform construction that namely quantity performed is huge in high quality under shorter time and less personnel put into, save engineering time and cost.
