A connector comprises connection sleeves which are communicated with one ends of grouting pipe connectors, the other ends of the grouting pipe connectors are communicated with rigid plastic pipes, the axis of the grouting pipe connectors and that of the rigid plastic pipes are on a same straight line, an included angle of 45 degrees is formed between the axis of the grouting pipe connectors and that of the rigid plastic pipes, and one ends of the connection sleeves are connected with a prestressed pipeline while the other ends of the connection sleeves are connected with anchor subplates. The continuous beam vertical prestressed pipeline connection structure has the advantages that blockage of the vertical prestressed pipeline is effectively prevented, and grouting of the continuous beam vertical prestressed pipeline is guaranteed, so that the service life of a continuous beam is guaranteed, manpower, financial resources and material resources consumed for searching blocked pipelines manually are avoided. Consequently, the continuous beam vertical prestressed pipeline connection structure has good economic and social benefits.
Description
Technical field
The utility model belongs to the technical field of continuous beam vertical prestressing pipeline construction, is specifically related to a kind of continuous beam vertical prestressing pipe connecting structure.
Background technology
Along with the fast development of high-speed railway and speedway, stride highway, stride railway, cross a river high pier continuous beam increases gradually.Original vertical prestressing pipeline connection technology all is to adopt direct insertion connected mode, directly is inserted into the plastic pipe of prestress pipe, defaults in together in the concrete then ventilation of a mud jacking.This connected mode is to have many-sided shortcoming, because vertical prestressing pipe design internal diameter is generally 35mm, wall thickness is 0.5mm, the prestressed reinforcement diameter is generally 25mm, between the space very little, cause the plastic pipe diameter of use to be very restricted, and deflection occurs in plastic pipe easily in default process, pressure is larger when causing mud jacking like this, and effect is quite undesirable, and there is clogging in most vertical prestressing pipeline.
Summary of the invention
The utility model all is to adopt direct insertion connected mode to cause mud jacking plugging phenomenon more serious in order to solve existing continuous beam vertical prestressing pipeline connection technology, and the high problem of construction cost.
The present invention adopts following technical scheme to realize:
Continuous beam vertical prestressing pipe connecting structure, it comprises the connector that is connected respectively with vertical prestressing pipeline upper and lower side, described connector comprises splicing sleeve, an end that is communicated with the Grouting Pipe connector on the splicing sleeve, the other end of Grouting Pipe connector is communicated with again the hard plastic pipe, the axis of the axis of Grouting Pipe connector and hard plastic pipe point-blank, the axis of Grouting Pipe connector axis and splicing sleeve is 45° angle, splicing sleeve one end connects prestress pipe, the other end connects anchor plate, the distance that the intersection point of the axis of Grouting Pipe connector axis and splicing sleeve and splicing sleeve close on anchor plate one end end is 1/3rd of splicing sleeve total length, Grouting Pipe connector deflection anchor plate one side.
The utlity model has following beneficial effect: the clogging that has effectively prevented the vertical prestressing pipeline, guaranteed the slip casting of continuous beam vertical prestressing pipeline, then guaranteed the application life of continuous beam, manpower, financial resources and the material resources of having avoided artificial searching blocking pipe to spend.Have good economic benefit and social benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Among the figure: 1-splicing sleeve, 2-Grouting Pipe connector, 3-anchor plate, 4-hard plastic pipe, 5-vertical prestressing pipeline, 6-finish rolling deformed bar.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
1), the composition of connector
Connector mainly is divided into splicing sleeve, Grouting Pipe connector, anchor plate.An end that is communicated with Grouting Pipe connector 2 on the splicing sleeve 1, the other end of Grouting Pipe connector 2 is communicated with again hard plastic pipe 4, the axis of the axis of Grouting Pipe connector 2 and hard plastic pipe 4 point-blank, the axis of Grouting Pipe connector 2 axis and splicing sleeve 1 is 45° angle, splicing sleeve 1 one ends connect prestress pipe 5, the other end connects anchor plate 3, the distance that the intersection point of the axis of Grouting Pipe connector 2 axis and splicing sleeve 1 and splicing sleeve 1 close on anchor plate 3 one end ends is 1/3rd of splicing sleeve 1 total length, Grouting Pipe connector 2 deflection anchor plates 3 one sides.
2), connector material is selected
Splicing sleeve: because the general internal diameter of vertical prestressing pipeline is φ 35mm in the Continuous beam design, wall thickness is 0.5mm, therefore selecting the connector tube material is that internal diameter must be φ 42.5mm so select common external diameter greater than φ 36mm, and wall thickness is that the steel pipe of 3.25mm is splicing sleeve.
The Grouting Pipe connector: be connected firm connection with splicing sleeve for the rigidity requirement that guarantees the Grouting Pipe connector, select common steel tube internal diameter φ 15.8mm, wall thickness is 2.75mm.
Anchor plate: anchor plate is continuous beam vertical prestressed anchor backing material, JLM-25.
3), connector procedure
Connector has two groups, can be referred to as connector and lower connector, and upper connector is corresponding to upper anchor plate, and lower connector is corresponding to lower anchor plate.
A, be φ 42.5mm with external diameter, wall thickness is the short steel pipes that the common steel tube of 3.25mm is cut into 20cm one joint, and section is polished, and forms splicing sleeve.
B, with internal diameter φ 15.8mm, wall thickness is that the common steel tube of 2.75mm blocks into 10cm one joint short steel pipes, section is 45 ° of oblique angles and polishes, and to increase circulation area, forms the Grouting Pipe joint.
C, the Grouting Pipe connector is welded in 1/3rd places of splicing sleeve according to 45° angle, the hole need to be drawn with splicing sleeve in the junction, and to form the connection form, welding will be made a noise solid, but does not allow its weldering is leaked,
D, splicing sleeve are welded on the central authorities of (descending) anchor plate, and welding must be firm, but do not allow its weldering is leaked,
4), the vertical finish rolling screw thread prestress pipe of assembling, at first draw the hole at the vertical prestressing pipeline place corresponding with the connector gap, be communicated with to form with the vertical prestressing pipeline, then finish rolling deformed bar is through in the vertical prestressing pipeline, at last upper (descending) connector is enclosed within on the vertical prestressing pipeline, and with its sealing mortar leakage prevention;
5), the setting of mud jacking end, outlet side
In order to guarantee that mud jacking end, outlet side expose concrete surface, adopt the hard plastic pipe identical with Grouting Pipe connector external diameter to draw concrete surface.During connection, make it softening the heating of hard plastic pipe first, then insert rapidly the Grouting Pipe connector, outer lap length is not less than 6cm, uses after its cooling at last.
