Abstract
The invention discloses an anchor head arranged in a concrete faceplate. The anchor head comprises an anchor cable, an anchor head body, a steel base plate, channel steel and the cast-in-place concrete faceplate, wherein the anchor cable penetrates through an anchor hole performed in a side slope in advance, and the incoming end of the anchor cable is fixed by pouring cement paste after the anchor cable penetrates through the anchor hole; the cast-in-place concrete faceplate is arranged on the outer wall of the side slope internally provided with two layers of reinforcement fabrics, and the channel steel is clamped between the two layers of reinforcement fabrics; the anchor cable stretches into the cast-in-place concrete faceplate, penetrates through the double-channel steel and is fastened to the outer wall of the double-channel steel through the anchor head body finally; the steel base plate is arranged between the anchor head body and the outer wall of the channel steel, and the anchor cable also penetrates through the steel base plate. By adopting the technical scheme, through the arrangement of the channel steel and the two layers of reinforcement fabrics, the supporting and protecting stability is guaranteed, and the overall structure and the durability are greatly improved.
Description
Technical field
The present invention relates to civil building, water conservancy and hydropower, highway, railway construction engineering etc. for slope retaining field, be particularly a kind ofly placed in anchor head in concrete slab and construction method thereof.
Background technology
In slope project, the instability of exposed rock stratum forms harm to the Safety Section of building, need carry out supporting to administer.Anchor cable is as a kind of side slope antiskid structure; general routine adopts the mode of Shi Hanzhang to carry out reinforcing side slope; concrete protective surface layer generally adopts sprayed mortar or cast-in-situ concrete; anchor pad pier is generally external; adopt pouring concrete, during this form construction, after needing anchor pier to reach some strength, carry out slip casting; and reach after desired strength until slurries and just can carry out stretch-draw, finally carry out sealing off and covering anchorage with concrete.But anchor pier reaches certain intensity needs the regular hour, the corrosion resistance of another billet and period of validity comparatively concrete are poor, are very easily subject to the corrosion of rainwater.
Summary of the invention
The present invention is directed to above-mentioned technical problem, proposing one can the reduction of erection time, meet again life requirement can be used for slope retaining be a kind ofly placed in anchor head in concrete slab and construction method thereof.
For reaching above object, be achieved through the following technical solutions:
Be placed in the anchor head in concrete slab, comprise: anchor cable, anchor head, billet, channel-section steel and cast-in-situ concrete panel;
Wherein, anchor cable penetrates in advance in the anchor hole that side slope is accomplished fluently, and anchor cable inserting end is fixed by casting cement slurry after penetrating anchor hole by anchor cable;
Cast-in-situ concrete panel is arranged at side slope outer wall;
Be built-in with two-layer steel mesh reinforcement in cast-in-situ concrete panel, and be clamped with channel-section steel between two-layer steel mesh reinforcement; Its stream line stretches into cast-in-situ concrete panel itself and through double flute steel, is anchored on double flute steel outer wall eventually through anchor head;
Be provided with billet between anchor head and channel-section steel outer wall, namely anchor cable is equally through billet.
Be placed in a construction method for the anchor head in concrete slab, comprise the following steps:
Step one, first smooth side slope surface, then opens anchor hole in side slope, then is stretched into by anchor cable, fastening finally by pouring into a mould M30 cement paste in anchor hole;
Step 2, first lay one deck steel mesh reinforcement, arrange double flute steel at steel mesh reinforcement outer wall, anchor cable runs through this one deck steel mesh reinforcement and channel-section steel successively, and the stretch-draw then carrying out anchor cable locks anchor cable finally by the assembling of anchor head and billet; Wherein, according to the difference of prestressd anchor cable, selected the channel-section steel of different model and varying number by correlation computations;
Step 3, then lays opposite side steel mesh reinforcement at channel-section steel outer wall, and realizes the overlap joint of steel mesh reinforcement at two-layer steel mesh reinforcement edge;
Step 4, by formwork supporting plate, and carries out concreting, and forming thickness is the topping of 50mm, completes sealing off and covering anchorage work.
The present invention of technique scheme is adopted to have the following advantages:
1, this anchor head structural shape can overcome the low shortcoming of conventional support pattern durability.
2, separately anchor head is built-in reduces the erosion of rain drop erosion to anchor head structure, avoids pedestrian to climb and causes unnecessary danger, adds somewhat to the safety of side slope.
3, anchor head is built-in can integral construction, shortens the duration.
4, the surfacing of this anchor head pattern is succinct, can promote the overall appearance degree of environment.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of manual, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
