Abstract
The utility model is a clamping apparatus with dual steel pipes, which comprises a cartridge cross beam. On top end of the cross beam, a connection part fixed onto a pressure device is provided; the cartridge is movably connected below the cross beam; the cartridge comprises a fixed splint and a replaceable movable splint; the movable splint is movably linked to the fixed splint; the hydraulic cylinder is fixed to connect with the movable splint; besides, a wedging block is also included to match with the cartridge; the wedging block is embedded inside a drum hole that is formed with sleeve pipes on the internal and external protective walls. The wedging block is secured onto the circular crown plate; the radial width where the circular crown plate offsets the cartridge is slightly larger than the radial width of corresponding drum holes. The utility model of clamping apparatus is connected with the sleeve pipes through the cartridge, so that the clamping apparatus can be removed after pressure piling; then, the reinforcing cage can be placed into the drum hole, in order to prevent the reinforcing cage from being damaged when being pressed; the clamping apparatus is equipped with the wedging block that is embedded inside the drum hole, so that sleeve pipe deformation can be reduced; the reinforcing cage can be directly put in from the top end of the drum hole without necessity of elevating the sleeve pipe, for which execution difficulty can be considerably lowered.
Description
(1) technical field
The utility model relates to a kind of steel pipe pile anchor clamps, especially is suitable for and bitubular pilework.
(2) background technology
In prior art, as being 98113070.4 in the patent No., name is called in the patent of invention of the job practices of the concrete barrel that is embedded in subgrade and forced one-shot forming device, a kind of tube forming pile device of double-cylinder type is disclosed, it is that inside and outside retaining wall cover is fixedly connected on the gland, directly sleeve pipe is exerted pressure during piling by gland, the fixed structure of this gland and protection casing makes and has following shortcoming in the work progress: 1, must be placed on reinforcing cage in the hole earlier before exerting pressure, and then exert pressure, reinforcing cage is impaired easily; 2, need promote certain altitude to sleeve pipe could be placed into reinforcing cage in the hole, and construction intensity is big, difficulty is big; 3, exert pressure and make casing deformation easily; 4, need gland and above force application apparatus on offer mudhole.
(3) summary of the invention
Fixedly connected with sleeve pipe in order to overcome above-mentioned gland that existing reinforcing cage is impaired easily, construction is complicated, the deficiency of sleeve pipe easy deformation, provide a kind of simple in structure, flexibly connect, avoid the impaired two steel pipe pile anchor clamps of reinforcing cage with sleeve pipe.
For this reason, the technical solution adopted in the utility model is: a kind of pair of steel pipe anchor clamps, include the chuck crossbeam, the upper end of crossbeam is provided with device for exerting and is fixedly coupled part, and chuck is movably connected in described crossbeam below, and described chuck includes strap and removable moving clamping plate, described moving clamping plate and strap flexibly connect, hydraulic jack is fixedlyed connected with described moving clamping plate, also includes the voussoir that cooperates with described chuck, and described voussoir is embedded in the tube hole of inside and outside protection casing formation.
Further, described voussoir is connected with described sleeve pipe by fastener, is fixed in the described wall chamber.
Further, described voussoir is fixed on the annular roof plate, and the radial width that described annular roof plate departs from the clip position place is slightly larger than the radial width in corresponding tube hole.
Further, described voussoir is the voussoir group of primary and secondary structure, and female voussoir is fixed on the described top board, and removable sub-voussoir is connected with described female voussoir, and described voussoir group can closely place in two steel pipe barrel chambeies by changing sub-voussoir.
The utility model has the advantages that: 1, anchor clamps are connected by chuck with sleeve pipe, can unload lower clamp behind the piling back of exerting pressure, and reinforcing cage are placed in the hole again, avoid reinforcing cage impaired when exerting pressure; 2, anchor clamps are furnished with the voussoir that embeds in the tube hole, can reduce casing deformation; 3, simple in structure, mudhole needn't be set; 4, reinforcing cage is directly put into from upper end, tube hole, need not to promote sleeve pipe, greatly reduces difficulty of construction.
(4) description of drawings
Accompanying drawing 1 is the utility model (unloading lower wedge block) structural representation
Accompanying drawing 2 is annular roof plate schematic diagrames described in the utility model
Accompanying drawing 3 is work schematic diagrames described in the utility model
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing, a kind of pair of steel pipe anchor clamps, include chuck crossbeam 1, the upper end of crossbeam is provided with device for exerting and is fixedly coupled part 2, chuck is movably connected in described crossbeam 1 below, described chuck includes strap 4 and removable moving clamping plate 3, described moving clamping plate 3 flexibly connect with strap 4, hydraulic jack 13 is fixedlyed connected with described moving clamping plate 3, also include the voussoir 5 that cooperates with described chuck, described voussoir is embedded in internal wall protecting casing 6, in the tube hole 8 that outer protection casing 7 forms, described voussoir 5 is fixed on the annular roof plate 9, described annular roof plate 9 departs from the radial width of the radial width at clip position place greater than corresponding tube hole, and described top board places described pair of steel pipe tube upper surface.Described voussoir 5 is the voussoir group of primary and secondary structure, and female voussoir 10 is fixed on the described top board, and removable sub-voussoir 11 is connected with described female voussoir, and described voussoir group can closely place in two steel pipe tube tube holes 8 by changing sub-voussoir.Described top board below also be provided with two with described pair of steel pipe tube tube hole coupling, and the fixed block 12 of described voussoir " ten " word symmetry.
When conversion clamps steel pipe, earlier anchor clamps are unclamped, unload moving clamping plate 3, change the moving clamping plate that mate with folded steel pipe, annular roof plate 9 is pulled out in the tube hole together with the primary and secondary voussoir, change sub-voussoir 11, two steel pipe tubes are clamped voussoir 5 embeddings and tube hole 8 interior getting final product in position between alignment jig.
