Abstract
The utility model discloses a hinged drawing type steel internal die which comprises a first member and a second member. The first and second members are both divided into two segments arranged symmetrically up and down, and the upper and lower segments are hinged by a hinge point. The first and second members are connected by an oblique wedge joint. An arm plate is arranged between the upper and lower segments of the first and second members. The arm plate is divided into an upper section and a lower section, and the upper and lower sections are connected by a pull rod. The hinged drawing type steel internal die has the advantages that the quality defects that the traditional airbag internal die is difficult to position and easy to float up, causes exposed tendons, distorted internal chamber, linear non-straightness and the like are avoided; the hinged drawing type steel internal die has the characteristics of simple operation, convenient de-molding, greatly shortened assembly and disassembly time and convenient use; and the hinged drawing type steel internal die reduces the cost, improves working efficiency, gets remarkable economical benefit and is easy to popularize.
Description
Technical field
The utility model relates to the highway bridge construction field, particularly relates to a kind of hinged drawing and pulling type steel internal mold.
Background technology
In the highway bridge construction; The used plate-girder internal mold of the tradition prefabricated worker's method of hollow slab beam adopts contour forming in the rubber pneumatic bag more, because the intrinsic propesties of rubber pneumatic bag, its rigidity is not enough; The inner inflatable body; The big location difficulty of buoyancy, so the physical dimension of internal mold is prone to produce distortion, come-up, mass defect such as the common dew muscle of hollow slab beam internal mold contact surface of shaping, linear dimension error are big.And application life is on the low side to be unfavorable for down usefulness, in case damaged difficult the reparation, input cost is bigger.
The utility model content
The utility model has overcome the shortcoming in the present technology, and a kind of hinged drawing and pulling type steel internal mold is provided.
The technical scheme of the utility model is: a kind of hinged drawing and pulling type steel internal mold, comprise first member and second member, and first member and second member are divided into laterally zygomorphic two sections, and two sections are hinged through pin joint up and down; Adopt oblique wedge mouth seam to connect between first member and second member; First member and second member be provided with the arm plate between two sections up and down, the arm plate is divided into two sections, and connects through pull bar between the two sections.
Second member is provided with hinged flat segments, and is hinged through pin joint between two sections up and down of second member and the two ends of hinged flat segments.
Compared with prior art, the utility model has the advantages that: avoided traditional use air bag internal mold location difficulty, be prone to come-up, produced mass defect such as reveal muscle, inner room distortion, linearity is not straight; Have simple to operate, the demoulding is convenient, shorten to install significantly, the dismounting time, convenient characteristics of falling usefulness have reduced cost and have improved work efficiency, remarkable in economical benefits is easy to promote.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of hinged drawing and pulling type steel internal mold;
Fig. 2 is the preceding user mode figure of moulding/demoulding in the hinged drawing and pulling type steel;
Fig. 3 is the user mode figure behind the moulding/demoulding in the hinged drawing and pulling type steel.
The specific embodiment
A kind of hinged drawing and pulling type steel internal mold; Extremely shown in Figure 3 like Fig. 1; Comprise: first member 1, second member 2, hinged flat segments 3, pull bar 5 and arm plate 6; Wherein: first member 1 and second member 2 are divided into laterally zygomorphic two sections, and two sections up and down of first member 1 are hinged through pin joint, and it is hinged to pass through pin joint between two sections up and down of second member 2 and the two ends of hinged flat segments 3; Adopt oblique wedge mouth seam to connect between first member 1 and second member 2; First member 1 and second member 2 be provided with arm plate 6 between two sections up and down, be used to support internal mold; Arm plate 6 is divided into two sections, connects through pull bar 5 between two sections.Outwards during pumping mode, only need two sections up and down of pulling pull bar 5, the first members 1 and second member 2 to rotate through hinge; Arm plate 6 is inwardly shunk, and the last sections of first member 1 and second member 2 falls, and is easy to operate, flexible; Dismounting speed is fast, and long service life is outwards laborsaving during pumping mode.
Through hinged flat segments 3, can control the stroke of second member, 2 hinged expansion, enlarge demoulding distance as far as possible, first member 1 and second member 2 interfere and influence the demoulding when avoiding the demoulding.
