Abstract
The invention discloses a wedge pressure anchorage device based on powder concrete application. The appearance of a steel anchorage cup is machined to be in a step shape, and a powder concrete high-pressure forming technology is applied to embed the steel anchorage cup into the device to be cured at the high temperature and high pressure for 48 hours; and the pressure-resisting strength of powder concrete can reach more than 300Mpa and can approach to the pressure resisting strength of a steel material. The contact area between the anchorage device and concrete is expanded, and local stress of anchorage concrete is smaller than the pressure-resisting design strength of a concrete structure. The wedge pressure anchorage device has the advantages that an embedded anchorage pad plate in a concrete structure can be eliminated, and structural peripheral construction reinforcing steel bars are reduced accordingly; vibratory compaction of the concrete is facilitated, and the greatest advantage is that even diffusion and distribution of the prestress in the concrete structure is facilitated, the service life of the concrete structure is prolonged, the construction quality is ensured better, and the engineering cost is correspondingly reduced.
Description
Technical field
The present invention relates to ground tackle product technical field, particularly relate to a kind of embedding pressure ground tackle based on the application of powder concrete.
Background technology
Along with high strength steel is widely used among long span building structure, the use amount of prestressed anchor is also in continuous increase.Ground tackle is the necessary device to structure Shi Hanzhang, usually be made up of anchor cup, intermediate plate and anchor plate, the stretching force of jack is passed to anchor cup by intermediate plate by high tensile steel wire, and power is passed to again the anchor plate be attached thereto by anchor cup, and power is diffused among concrete structure by anchor plate again.Because concrete compressive strength only can reach about 50Mpa, anchor plate periphery concrete needs to configure more distributing bar, the concentrated force that ground tackle could be transmitted is diffused among concrete structure far away equably, and affect because reinforcing bar is too close during site operation and vibrate, often have, because of concrete vibrating leakiness, the phenomenons such as anchor plate destruction, concrete local chips occur.Easily there is localized cracks at the stress concentrated position of prestress anchoraging in some large bridges, affect structure application life in operation process.
Summary of the invention
The object of the present invention is to provide a kind of embedding pressure ground tackle based on the application of powder concrete, the new product of the embedding pressure ground tackle of a kind of high strength powder is provided, the key of this ground tackle is that the sharp processing of steel anchor cup is become step, powder concrete high-pressure molding technique is used to be embedded wherein by steel anchor cup, HTHP maintenance 48 hours, the compressive strength of powder concrete can reach more than 300Mpa, can close to the compressive strength of steel.Its object expands ground tackle and concrete contact area exactly, the local stress of concrete below anchor is made to be less than the resistance to compression design strength of concrete structure, its advantage to cancel pre-buried anchor plate in concrete structure, structural perimeter distributing bar also can reduce thereupon, be conducive to concrete vibration compacting, maximum advantage is conducive to prestressing force even diffusion profile in concrete structure, can improve the application life of concrete structure, construction quality is more guaranteed, and construction costs also can correspondingly reduce.
For effectively solving the problems of the technologies described above, the technical scheme that the present invention takes is as follows:
Based on the embedding pressure ground tackle of powder concrete application, comprise steel anchor cup and powder concrete two parts, described steel anchor cup build-in wherein makes its consolidation be integral type combining structure by described powder concrete, described steel anchor cup lateral surface is terraced structure, and comprise an endoporus, described endoporus is conical bore, described powder concrete liner ring like steel wire.
Especially, described steel anchor cup comprises single hole anchor cup and porous anchor cup, and the lateral surface step of described single hole anchor cup can be divided into 4 grades, and the lateral surface of described porous anchor cup can be divided into multi-stage stairs according to ground tackle height.
Especially, the compressive strength of described powder concrete is no less than 300Mpa.
Especially, described powder concrete is truncated cone-shaped, and establishes ring like steel wire in inside lining.
Especially, described powder concrete comprises mud jacking hole.
Beneficial effect of the present invention is: the embedding pressure ground tackle based on the application of powder concrete provided by the invention, improve the phenomenon that concrete structure local pressure is excessive, can extending structure application life, by powder concrete ground tackle, end bearing area is increased, δ=F/S(δ stress, F pressure, S bearing area), normal pressure F is constant, and S increases, and stress δ diminishes; Anchor cup and embedding accessory kit--the anchor plate of pressing the ground tackle of one can cancel existing anchoring system of powder concrete, the effect of anchor plate is exactly be diffused among concrete structure by the concentrated force of ground tackle, and this patent product solves this problem well, anchor plate loses the value of existence naturally; Along with construction technology simplifies and accessory minimizing, construction cost is also along with decline; Because local structure reinforcing bar reduces, the easier vibration compacting of structural concrete, workmanship is more guaranteed; The labour intensity of construction worker also reduces thereupon.
