Abstract
The utility model discloses a device for controlling tensioning of prestressed reinforcements of a track plate, comprising an anchor recess pad plate pre-embedded in concrete, an anchor recess cone fixedly connected with the anchor recess pad plate, and a side mold fixedly connected with the anchor recess cone; the anchor recess cone is provided with a central hole that is internally provided with a fastening bolt which is connected with the prestressed reinforcement; a rubber pad is arranged between the anchor recess cone and the side mold; the rubber pad is connected with the anchor recess cone and the side mold by bolts; and the rubber pad is connected with the anchor recess cone, the side mold and the anchor recess pad plate by bolts. The device has simple structure, good use effect, low cost and high efficiency, reduces heavy physical labor, and is humanized.
Description
Technical field
The utility model relates to the device of deformed bar stretch-draw, relates in particular to a kind of device that is used to control the track slab prestress reinforced bar stretching.
Background technology
The device of the control track slab prestress reinforced bar stretching that China is at present used, comprise the anchor recess backing plate that is embedded in the concrete, the anchor recess backing plate is connected with anchor recess cone, side form by bolt, and the anchor recess cone is provided with centre bore, and the fastening bolt that is connected with deformed bar is installed in the hole.Deformed bar is to add fastening bolt at the center of anchor recess cone to fix, and when the railway plate die side form was opened, side form drove that the anchor recess cone is outer together moves, in moving process, and the anchor recess cone concrete of can damaging, pin easily stretches tight; Said structure enters in the bolt hole when concreting re-packs easily, cause bolt to twist not come out, be easy to generate crackle, damage during the demoulding of track plate, and working strength of workers is big, efficient is low, cost is high, the track plate poor quality who is shaped can't adapt to present development of high-tech fully.
The utility model content
The purpose of this utility model is just in order to overcome above-mentioned deficiency of the prior art, a kind of device that is used to control the track slab prestress reinforced bar stretching is provided, the track plate that uses this device to be shaped is bright and clean, beautiful, concrete crackle useless, the pin that stretches tight, and quality is good, and this device uses efficient and convenient laborsaving.
The utility model is achieved by following technical proposals: a kind of device that is used to control the track slab prestress reinforced bar stretching, comprise the anchor recess backing plate that is embedded in the concrete, the anchor recess cone affixed with the anchor recess backing plate, the side form affixed with the anchor recess cone, the anchor recess cone is provided with centre bore, the fastening bolt that is connected with deformed bar is installed in the hole, be provided with rubber blanket between described anchor recess cone and the side form, described rubber blanket is connected by bolt with side form with the anchor recess cone, is connected by bolt with anchor recess cone, side form, anchor recess backing plate.
The periphery of described rubber blanket is provided with tapering.
The tapering of described rubber blanket periphery is: 5 °～25 °.
The thickness of described rubber blanket is: 5mm～30mm.
The beneficial effects of the utility model are: simple in structure, result of use is good, and cost is low, and the efficient height reduces heavy manual labor, hommization.
Description of drawings
Fig. 1 is the utility model structural representation.
Reference numeral: 1, side form, 2, rubber blanket, 3, the anchor recess cone, 4, concrete, 5, deformed bar, 6, the anchor recess backing plate, 7, bolt, 8, fastening bolt, 9, bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, a kind of device that is used to control the track slab prestress reinforced bar stretching of the utility model is provided with rubber blanket 2 between anchor recess cone 3 and side form 1, and anchor recess cone 3, rubber blanket 2, side form 1 link into an integrated entity by bolt 9; The anchor recess backing plate 6, anchor recess cone 3, rubber blanket 2, the side form 1 that are embedded in the concrete 4 connect by bolt 7; Anchor recess cone 3 is provided with centre bore, and the fastening bolt 8 that is connected with deformed bar 5 is installed in the hole.
The periphery of above-mentioned rubber blanket is provided with tapering.Tapering is: 5 °～25 °.
The thickness of rubber blanket is: 5mm～30mm.
When railway plate die side form 1 is opened, unclamp fastening bolt 8 and bolt 7 respectively, side form 1 drives rubber blanket 2, prestressed anchor recess cone 3 and moves outward together, in moving process, because rubber blanket is soft, can not bump concrete in moving process; Because rubber is lined with tapering, make concrete can not form wedge angle in addition, concrete is difficult for arrisdefect; And because rubber blanket has sealing function, concrete can not enter in the bolt hole when re-packing building, and bolt just can be turned on easily, can not crack during the demoulding of track plate, damage, reduce working strength of workers, the efficient height, cost is low, and the track plate quality of shaping is good.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
