Description
Technical field
The present invention relates to prestressed anchor component technology field, especially a kind of welded type anchor plate, and preparation method thereof.
Background technology
Current anchor plate is most of to be cast integrally using gray cast iron material, although gray cast iron material castability
Can be good with damping performance, but its tensile strength and plasticity are low, and the defect of cast member is a lot, and Producing reason is also a variety of more
There is uneven big crystal grain, crystal grain, chill phenomenon, crackle, cracking, overlap crackle phenomenon in sample, such as casting.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of welded type anchor plate, and clever structure is easy to use.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：A kind of welded type anchor plate, by supporting pad
Plate and supporting cylinder are formed, and the support backing plate is provided with presstressed reinforcing steel hole and grout hole；The supporting cylinder is by two shape sizes
The same semicircle cone cylinder splicing composition, the supporting cylinder larger open end is fixedly connected with the support backing plate；The prestressing force
Muscle hole and the grout hole are connected with the supporting cylinder.
Further, it is described to support backing plate and supporting cylinder to be that steel matter is made.
Further, the thickness of the support backing plate is 8~55mm.
Further, the wall thickness of the supporting cylinder is 1~5mm；Taper angle theta is not more than 3 °.
Further, the support backing plate lateral surface fixes step provided with anchor slab, is located at the week in the presstressed reinforcing steel hole
Enclose.
Further, the external diameter of the anchor slab fixation step is more than anchor slab 1~3mm of external diameter, and depth is 2~5mm.
A kind of preparation method of welded type anchor plate as described above, comprises the following steps：
(1), according to wanted matching used anchor slab, it is determined that the size of support backing plate, the punching press presstressed reinforcing steel in the middle part of the support backing plate
Hole and grout hole, and set anchor slab to fix step around the side of presstressed reinforcing steel hole；
(2) two block-shaped equirotal sheet materials, are taken, semicircle cone cylinder, one of upper madjack pipe of use stamping machine punching press one is made；
By two pieces of semicircle cone cylinder make-ups into taper cone barrel；
(3), the taper cone barrel for (2) making support backing plate and step that (1) step makes, it is integral by being welded to connect.
Compared with prior art, the present invention has advantages below：Using separately manufactured support backing plate and supporting cylinder, it is to avoid because
The reasons such as casting technique cause the unqualified problem of product to occur, and the interchangeability of separately manufactured support backing plate and supporting cylinder is strong, and one
It is individual it is unqualified can select another to carry out welding spelling group, evade and standardization requirement be not inconsistent at one just overall wasting phenomenon going out
It is existing.The old-fashioned anchor plate of taper ratio of supporting cylinder is small simultaneously, can preferably avoid the cut-out thing of the presstressed reinforcing steel in stretching process
Part occurs.And this anchor plate that design invention is applied to circle anchor, flat anchor and square anchorage are used, while its shape
Circular, flat can be designed to and square, it has a wide range of application, simple in construction easily fabricated.
Brief description of the drawings
Fig. 1 is the structural representation of welded type anchor plate of the present invention；
Fig. 2 is Fig. 1 right view；
Fig. 3 is Fig. 1 left view；
Diagram mark：
1 presstressed reinforcing steel hole, 2 grout holes, 3 support backing plates, 4 supporting cylinders.
Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings, and the description of this part is only exemplary and explanatory, should not
There is any restriction effect to protection scope of the present invention.
As shown in Figure 1,2 and 3, a kind of welded type anchor plate, is made up of support backing plate 3 and supporting cylinder 4, supports the He of backing plate 3
Supporting cylinder 4 is made of steel material.
The support thickness B of backing plate 3 takes 8~55mm thick, mainly carries the prestressing force of anchorage, can be according to different Kong Shu, difference
Prestressed anchor slab determines the thickness of support backing plate, so can not only meet the requirement of stretch-draw prestressing force but also mitigate the weight of anchor plate
Amount reduction manufacturing cost
Grout hole 2 on support backing plate 3 is stamped to form by stamping machine, then using special tapping tapping female bore, is easy to pre- answer
Mud jacking work after the completion of power tensioning.
Supporting cylinder 4 is made up of two the same half-conicals of shape size, and its thickness of slab b takes 1~5mm, and θ angles are not more than 3 degree, branch
Hold cylinder 4 to be rolled or be stamped to form by steel plate, and meet the coniform or semi-conical of Design Requirement Drawing.
The manufacturing process of above-mentioned welded type anchor plate：
1st, welded type anchor plate is made up of support backing plate 3 and supporting cylinder 4, replaces the ash during casting of old anchor plate to cast using steel
Iron improves the combination property of anchor plate to improve tension, compression strength and the plasticity of support backing plate.Support backing plate has mud jacking hole,
Presstressed reinforcing steel hole and the step of fixed anchor slab.
2nd, the size of presstressed reinforcing steel hole 1 of support backing plate 3 is determined by matched anchor slab, consolidating on support backing plate 3
Determine anchor slab step dimension 1~3mm bigger than anchor slab, δ and take 2~5mm.Mud jacking hole thereon stamps out grout hole 2 by stamping machine, then
Using special tapping tapping female bore, it is easy to the mud jacking work after the completion of prestressed stretch-draw.
3rd, supporting cylinder 4 is made up of two the same half-conicals of shape size, and its thickness of slab b takes 1~5mm, and θ angles are not more than 3 degree,
Mud jacking hole is stamped to form by stamping machine, then using special tapping tapping female bore, the connection for madjack pipe.Support cylinder 4 by
Thickness of slab b takes 1~5mm steel plates to roll or be stamped to form, and θ angles are not more than 3 degree, and meet the coniform or semicircle of Design Requirement Drawing
Taper.
4th, after support backing plate 3 and supporting cylinder 4 is made respectively, by welding manner, support backing plate 3 and supporting cylinder 4 are welded
It is connected into one.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
