Abstract
The utility model discloses a pattern self-anchor structure with hoop at the end of prestressing tendon, consisting of a pattern self-anchor structure and a steel hoop, which is characterized in that the pattern self-anchor structure has two forms of single pattern self-anchor structure and double pattern self-anchor structure. The front part of the single pattern self-anchor structure is provided with a first pattern steel hoop(2); the front part of a first pattern(1) of the double pattern self-anchor structure is provided with a first pattern steel hoop(2), and the front part of a second pattern(4) is provided with a second pattern steel hoop(5). The utility model can ensure that the pattern will not loose, with no change of the pattern size and no influence by the transportation, thereby effectively improving the usability of the pattern self-anchor structure.
Description
The utility model belongs to builing industry prestressed reinforcement technical field of construction.
The presstressed reinforcing steel end is that list spends type from anchor structure from anchor structure at present, is processed by embossing machine, and when taking out from embossing machine after the presstressed reinforcing steel embossing, the flower type shrinks bigger, and the end is prone to bigger diffusing colored situation, and external dimensions is wayward.In addition, in the laying installation process of presstressed reinforcing steel transportation and job site, the flower type can be subjected to the external force effect inevitably, the flower distortion that also can make it to loose, and this all can make reducing from the anchor function of presstressed reinforcing steel, does not reach the anchoring requirement.
The purpose of this utility model provides a kind of colored type of strap from anchor structure.This have single flower type and two kinds of forms of honeysuckle type from anchor structure, and deflection is very little after the moulding of flower type, and appearance and size is controlled easily, and is not yielding when being subjected to external force pressure, is convenient to transportation and on-the-spot shop muscle and installation.
The purpose of this utility model realizes by following mode: single flower type is in presstressed reinforcing steel end elder generation a stirrup to be installed before embossing from anchor structure, after in embossing machine, extruding the flower type, stirrup just can firmly block the presstressed reinforcing steel end, during taking-up, the flower type has obtained effective assurance from anchor structure from the anchor function.The honeysuckle type is to carry out twice embossing continuously from anchor structure, in the front portion of honeysuckle a stirrup is installed all, and the external dimensions of honeysuckle is controlled easily like this, and is not yielding, reliable and stable when being subjected to external force pressure.In addition, can be according to the specific requirement of engineering structures, place a steel anchor plate at flower type rear portion, also can increase colored type from the anchor function.The honeysuckle type from anchor structure can strengthen greatly the flower type in concrete from the anchor function, can reduce reinforcing bar during stretch-draw to concrete local compressive stress, eliminate the excessive and concrete splitting phenomenon that occurs of stress.In addition, can be according to the specific requirement of engineering structures, place a steel anchor plate at the second bundle flower type rear portion, also can increase colored type from the anchor function.
The utility model is described in further detail below in conjunction with accompanying drawing.Fig. 1 is that single flower type is from the anchor structure schematic diagram.Fig. 2 adds single flower type of steel anchor plate from the anchor structure schematic diagram.Fig. 3 be the honeysuckle type from anchor structure form schematic diagram, form by a bunch of flowers type (1), a bunch of flowers shaped steel hoop (2), the second bundle flower type (4) and the second colored shaped steel hoop of bundle (5).Fig. 4 adds the honeysuckle type of steel anchor plate from the anchor structure schematic diagram, is made up of steel anchor plate (3), the second bundle flower type (4), the second bundle flower shaped steel hoop (5), a bunch of flowers type (1) and a bunch of flowers shaped steel hoop (2).With reference to accompanying drawing, the flower type be single flower type from anchor structure and honeysuckle type from two kinds of forms of anchor structure from anchor structure, and single type of spending is provided with a bunch of flowers shaped steel hoop (2) from the front portion of anchor structure.The honeysuckle type is provided with a bunch of flowers shaped steel hoop (2) from a bunch of flowers type (1) front end of anchor structure, and its second bundle flower type (4) front end is provided with the second bundle flower shaped steel hoop (5).The outer dia of flower type is 5 to 65 times of presstressed reinforcing steel diameter.The length of flower type is 80 to 150mm.Stirrup length is 8 to 10mm, and wall thickness is 2 to 3mm.A bunch of flowers shaped steel hoop (2) is 10 to 20mm apart from presstressed reinforcing steel end distance.In Fig. 3 and Fig. 4, the distance between a bunch of flowers type and the second bundle flower type is 40 to 80mm.
The utility model has been owing to adopted the structural form of stirrup, thus the colored type of presstressed reinforcing steel end from anchor structure after moulding, can guarantee not loose flower, flower molded dimension constant, be not subjected to transport and influence, improved the usability of colored type from anchor structure.
Claims (4)
1, the colored type of presstressed reinforcing steel end strap is from anchor structure, form from anchor structure and stirrup by the flower type, it is characterized in that the flower type from anchor structure for single flower type from anchor structure and honeysuckle type from two kinds of forms of anchor structure, single flower type is provided with a bunch of flowers shaped steel hoop (2) from the front portion of anchor structure; The honeysuckle type is provided with a bunch of flowers shaped steel hoop (2) from a bunch of flowers type (1) front end of anchor structure, and its second bundle flower type (4) front end is provided with the second bundle flower shaped steel hoop (5).
2, the colored type of presstressed reinforcing steel according to claim 1 end strap is from anchor structure, and the outer dia that it is characterized in that flower type (1) (4) is 5 to 6.5 times of presstressed reinforcing steel diameter, and the length of flower type (1) (4) is 80 to 150mm.
3, the colored type of presstressed reinforcing steel according to claim 1 end strap is from anchor structure, and the length that it is characterized in that stirrup (2) (5) is 8 to 10mm, and wall thickness is 2 to 3mm, and a bunch of flowers shaped steel hoop (2) is 10 to 20mm apart from presstressed reinforcing steel end distance.
4, the colored type of presstressed reinforcing steel according to claim 1 end strap is from anchor structure, it is characterized in that distance between a bunch of flowers type and the second bundle flower type is 40 to 80mm.
