In accompanying drawing:
Bearing 01, upper pinner 02, upper steel plate 03, pinner formwork structure 04, the first panel 10,Two panels 11, back cord 12, triangle back cord 13, screw rod 14, locking member 15, blast pipe 16 and groutingPipe 17.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in further details.
The utility model provides a kind of pinner formwork structure, and its structure as depicted in figs. 1 and 2, comprising:
The first panel 10, the second panel 11, back cord 12, the triangle back of the body wedge 13, screw rod 14 and locking member15。
The length of above-mentioned the first panel 10 is greater than the length of the second panel 11, and the two adopts thickness to beThe phenolic aldehyde bamboo plywood coated with film of 1.0cm~2cm, adopts woodworking machinery machine-shaping according to on-the-spot pinner size.The first panel 10 is two, the identical and positioned opposite of shape; The second panel 11 is two, shape phaseWith and be oppositely disposed between two described the first panels 10, and in surrounding with described the first panel 10Cavities, this cavity holds upper pinner to be repaired.
Above-mentioned back cord 12 is two, and it adopts the lumps of wood, and as adopted the 3*4 lumps of wood, it is separately positioned on phaseTo the outside of the first panel 10 of arranging, between itself and the first panel 10, fix with iron nail.
In order to reinforce the utility model, the outside of above-mentioned the second panel 11 also can arrange back cord 12, twoBetween person, fix with iron nail.
The two ends of above-mentioned screw rod 14 is passed respectively the first panel 10 of positioned opposite, this screw rod successively14 can adopt the screw rod of φ 14~φ 18, preferably adopt the screw rod of φ 16.
Above-mentioned triangle back of the body wedge 13 is processed with the lumps of wood according to on-the-spot actual angle, and it is inserted in above-mentioned screw rod 14Two ends, and near the outside of back cord 12, and use the locking member 15 supporting with above-mentioned screw rod 14 (asNut and packing ring) fastening.
The side of above-mentioned pinner formwork structure is also offered grout hole and is penetrated grout pipe 17. This grout pipe 17Least significant end exceed the upper surface of pinner on bearing. This grout pipe close is inserted in one end of this grout pipe 17Envelope, the other end exceeds the upper surface of pinner formwork structure. This grout pipe can be pvc pipe, also canFor steel pipe, diameter is Φ 30mm~Φ 70mm, preferably Φ 50mm.
Above-mentioned pinner formwork structure is also buried one or more blast pipes 16 underground. This blast pipe 16 can be buried undergroundAt the side of pinner formwork structure, also can be embedded in first panel 10 and second of pinner formwork structureIn the inner space that panel 11 surrounds. When blast pipe 16 is embedded in the side of pinner formwork structure,Need the corresponding side at pinner formwork structure to offer multiple steam vents 16 and at itself and blast pipe 16Cooperation place good seal. When blast pipe 16 is embedded in internal cavities, the least significant end of this blast pipe 16 is highIn the upper surface of the upper steel plate 03 of upper pinner 02 bottom, most significant end is higher than the upper table of pinner formwork structureFace. This blast pipe 16 can be pvc pipe, can be also the pipe of other material, as rubber tube, steelPipe etc., diameter is Φ 10mm~Φ 30mm, preferred diameter is Φ 20mm.
Enrich for the position grouting that ensures to come to nothing, in the utility model, one of them blast pipe 16 connectsHave elbow, upward, the other end of elbow also can be connected with blast pipe and match the other end of its elbowAdd senior executive; Equally, one of them grout pipe 17 is connected with elbow, the other end of its elbow upward,The other end of elbow also can be connected with grout pipe matches and add senior executive. Can ensure like this blast pipeOr the most significant end of grout pipe and the distance of least significant end are not less than the difference in height threshold value of setting, thereby canCome to nothing position grouting of guarantee is enriched.
While using this pinner formwork structure, need to be at the surrounding Assembling of upper pinner to be repaired. GroupWhen dress, first a pair of back cord 12 is placed on respectively to the outside of two the first panels 10, then by firstPanel 10 penetrates respectively the two ends of screw rod 14, secondly installs successively three respectively at the two ends of screw rod 14Angle back of the body wedge 13 and locking member 15; Two the second panels 11 are arranged symmetrically with and are placed on the first panel 10Inner side, and with locking member 15 pretensions; Then adjust the position of the first panel 10 and the second panel 11,Make it be close to upper pinner to be repaired; Finally reinforce locking by locking member 15, form main template body,Mould seam crossing is sealed with sealing joint strip and quick-dry type fluid sealant; Then bury blast pipe 16 Hes undergroundGrout pipe 17, and by good the position seals of itself and the perforate of pinner formwork structure, form as shown in Figure 3Structure; Finally be in the milk by grout pipe 17 again.
Can be found out by above-mentioned embodiment of the present utility model, the utility model adopts Assembling, tears openThe mode of unloading designs, and adopts phenolic aldehyde film coating plywood to form template as panel and the little lumps of wood as back cordMain body, fixes to a pair of Screw arbor with nut at both-ends of back cord arranged outside along bridge, and close with sealing joint strip and quick-dry typeSealing is sealed mould seam crossing.
Although with preferred embodiment openly as above, embodiment does not limit this practicality to the utility modelNovel. Not departing from the spirit and scope of the utility model, any equivalence of doing changes or retouching,Belong to equally the protection domain of the utility model. Therefore protection domain of the present utility model should be with this ShenThe content that claim please defines is standard.
