Abstract
The utility model belongs to the technical field of urban construction engineering and relates to a concrete structure template supporting frame for a bridge V-type pier, in particular to a concrete structure template supporting frame adopting a balance inverted triangle for a bridge V-type pier. The concrete structure template supporting frame comprises two oblique beams (5) and a top beam (2), wherein the two oblique beams (5) are respectively fixed at two V-type legs of the bridge V-type pier, and the lower ends of the two oblique beams (5) are respectively connected with an embedded piece (6); the embedded pieces (6) are fixed on a pier table of the bridge V-type pier; and the top beam is horizontally mounted, and both ends of the top beam (2) are respectively fixedly connected to the upper ends of the two oblique beams (5). The concrete structure template supporting frame has the advantages of safe operation, quick construction and cost conservation, can be used for manufacturing a V-type pier structure in any case and has a good application prospect in the technical field of urban construction engineering.
Description
Technical field
The utility model belongs to the city construction engineering technical field, relates to a kind of bridge V-type pier concrete bracing frame, is specifically related to a kind of bridge V-type pier concrete structure formwork bracing frame that adopts balance inverted triangle structure.
Background technology
Bridge V-type pier structure is mainly formed the del structure by V limb and No. 0 piece.V-type pier battered leg is board-like concrete structure, and the battered leg axis and the pier center line angle of cut are generally 45
0About, fixed with case beam, pier base respectively up and down.
The V-type pier structure has reduced the span of case beam, mid span moment and all greatly minimizings of the simple power of bearing that the case beam is produced down at equal load action, so the cross section of box-beam structure and reinforcement ratio also can suitably reduce, and practiced thrift the engineering construction cost.Because V-type pier structure good looking appearance, construction cost is low, is therefore often adopted by design and Construction unit.
Conventional V-type pier concrete structure is a stiff skeleton, promptly buries stiff skeleton underground in the V limb, and V-type pier central authorities employing center balance pylon is held stiff skeleton and bed die, during No. 0 piece construction, through pylon load is directly passed to V-type pier bight.
When interior angle was big, No. 0 the beam projected area was very big, and load is bigger, and support force and stability in the bight all can not get guaranteeing, adopt the beam type support this moment usually.
Adopt the beam type support to need that the construction pile foundation is as the basis of support earlier, the cost of foundation pile is higher, and when the constructional difficulties than deeply time of the water level river course in.
More than can find out in two kinds of prior aries: if do not design stiff skeleton in the drawing design, unit in charge of construction can't adopt the stiff skeleton method to construct; Adopt beam type rack construction cost high and in the river course constructional difficulties under the water level condition with higher.
Summary of the invention
The utility model is to the deficiency of prior art; The inverted triangle balancing stand that a kind of steel pipe, shaped steel combination are provided is as V-type pier concrete structure formwork bracing frame; Handling safety, quick construction, saving cost, and be used in the making of V-type pier structure in any case.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
The concrete structure formwork bracing frame of bridge V-type pier; It is characterized in that: comprise two cant beams and a back timber, two cant beams are separately fixed at two V limbs inboards of bridge V-type pier, and the V limb is the battered leg of V-type pier; Two cant beam lower ends are connected with an embedded iron parts respectively; Embedded iron parts is fixed on the pier of bridge V-type pier, and the back timber level is set up, and the two ends of back timber are fixedly connected on two cant beam upper ends respectively.
As preferably, be provided with steel pipe post below the back timber, the steel pipe post upper end is connected with back timber through falsework, and the lower end is fixed on the pre-buried iron plate.Adopt four φ 203 steel pipes to form the center balance column of rectangular steel pipe frame as support, the lower end is fixed on the pre-buried iron plate; Can increase the width of column according to each steel pipe spacing of pier base size reasonable Arrangement as far as possible, improve the stability of the concrete structure formwork bracing frame self of bridge V-type pier.
As preferably, be provided with pull bar between back timber and the embedded iron parts, the pull bar level is set up, and the two ends of pull bar are individually fixed on two cant beams.
As preferably, pull bar has many, is set up in differentiated levels, and it is balanced to increase stress system.
Description of drawings
Fig. 1 is the structural representation of the concrete structure formwork bracing frame of the said bridge V-type of the utility model pier.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment

Back timber 2 belows are provided with steel pipe post 4, and steel pipe post 4 upper ends are connected with back timber 2 through falsework 1, and the lower end is fixed on the pre-buried iron plate 6.Adopt four φ 203 steel pipes to form the center balance column of rectangular steel pipe frame as support, the lower end is fixed on the pre-buried iron plate 6; Can increase the width of column according to each steel pipe spacing of pier base size reasonable Arrangement as far as possible, improve the stability of the concrete structure formwork bracing frame self of bridge V-type pier.
Be provided with two pull bars 3 between back timber 2 and the embedded iron parts 6, pull bar 3 levels are set up, and the two ends of pull bar 3 are individually fixed in two differing heights on the cant beam 5, and it is balanced to increase stress system.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
