Abstract
The utility model belongs to the field of the cast-in-situ engineering of a delivery pipe with large caliber. The utility model is composed of two semi-circular arc-shaped arced support frames whose cross sections form T shapes; the ends of the two semi-circular arc-shaped support frames are hinged symmetrically with a center; the rest ends of the two semi-circular arc-shaped support frames are connected by a reverse bolt. The inner mold support of a knee pipe is composed of the semi-circular arc-shaped support frames and a bivariate arc pad mold. The utility model has the advantages of low investment, manpower saving, convenient installation, construction and convenience, high laying speed, high quality, etc., and can be widely suitable for the cast-in-situ engineering of hafnium pipelines with large caliber and knee pipes.
Description
The utility model belongs to the cast-in-place engineering of heavy caliber conduit pipe field.
The deficiency of advanced " steel drags the mould construction method " is at present: (1) structure section is yielding; (2) construction time is long; (3) large diameter pipeline is not too adapted to; (4) end arch is built usually leakiness; (5) broken line shape curved pipe convection cell resistance is big.
The purpose of this utility model is the deficiency at above-mentioned prior art, and has designed a kind of less investment, economizes the labour, and speed of application is fast, heavy caliber hafnium pipeline that construction quality is high and bend pipe internal mold support device.
The technical solution of the utility model is: it is by two semicircular arcs, and its cross section is that "T"-shaped arc supporting frame is formed, and an end symmetry center of two semicircular arc supporting frames is hinged.Connect by reverse bolt between the other end of two semicircular arc supporting frames.The bend pipe internal mold supports by semicircular arc supporting frame and two arc pad moulds that become to be formed.
The utility model is compared with prior art, has less investment, economizes the labour, the installation convenient disassembly, and speed of application is fast, and fluid resistance is little, the quality advantages of higher.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model user mode schematic representation.
Fig. 3 is two arc pad mode structure schematic representation that become for the bend pipe internal mold supports.
The embodiment given below in conjunction with accompanying drawing describes in further detail the utility model: for stability and the rigidity that improves core, adopt the good "T"-shaped semicircular arc steel supporting frame (1) of stress performance power, for easy installation and removal, the one end symmetry center hinged (2) of two semicircular arc supporting frames (1) is connected by reverse bolt (3) between the other end of two semicircular arc supporting frames (1).For the accommodation curve pipeline, solve reinforced concrete pipiline not slick and sly difficult problem of broken line shape on circular curve segment in the past.Set up two change arc pad moulds (4), according to center line drift angle size, the radius of turn size is divided into each section with the pipeline arc section, is used by semicircular arc supporting frame (1) and two arc pad moulds (4) that become.When two change arc pad moulds (4) become predetermined radian in the power effect lower support of semicircular arc supporting frame (1).Only need the reverse bolt of degree of tightness (3) to finish when the need installing/dismounting, heavy caliber hafnium pipe and bend pipe job site implementation result are fabulous, and the labour is economized in the investment-saving, and speed is fast.The quality height.
Claims (2)
1, a kind of heavy caliber hafnium pipeline and bend pipe internal mold support device, it is characterized in that it is by two semicircular arcs, its cross section is that "T"-shaped arc supporting frame (1) is formed, two semicircular arc supporting frame (1) one end symmetry center hinged (2) are connected by reverse bolt (3) between the other end of two semicircular arc supporting frames (1)
2, heavy caliber hafnium pipe as claimed in claim 1 and bend pipe internal mold support device is characterized in that the bend pipe internal mold supports by semicircular arc supporting frame (1) and two arc pad moulds (4) that become to form.
