Abstract

A suspension-arm BBRV anchoring device comprises an upper anchor head, which is composed of an upper protective cover 1, an upper BBRV anchorage cup 2, an upper nut 3, an upper ball cushion 4, an upper seal drum 5, an upper embedded pipe 6, an upper shock absorber 7 and an upper buckler 8, which are connected in order; a suspension arm and string body 9; a lower anchor head, which is composed of a lower buckler 12, a lower shock absorber 13, a lower embedded pipe 14, a lower seal drum 15, a lower ball cushion 16, a lower seal drum 17, a lower BBRV anchorage cup 18 and a lower protective cover 19. The utility model is characterized in that: the BBRV anchorage cup 2 or the lower BBRV anchorage cup 18 is a BBRV anchorage cup with a tensioning interface, while the other is a flat anchorage cup, and an upper thermal shrinkage sleeve 10 and a lower thermal shrinkage sleeve 11 are respectively arranged at the small ends of the upper buckler 8 and the lower buckler 12 and outside the suspension arm and string body near the buckler. The external diameter of the BBRV anchorage cup of the anchor head and the internal diameters of the embedded pipe and the seal drums are smaller than the diameters of the common BBRV anchorage, so that the bridge cost can be reduced, the waterproof performance of anchor rods is good and the anticorrosion property is improved.

Description

Bulb-end anchorage suspension rod ground tackle
One, technical field:
The utility model relates to a kind of prestressed anchor, particularly a kind of bulb-end anchorage suspension rod ground tackle.
Two, background technology:
The existing bulb-end anchorage suspension rod ground tackle (as shown in Figure 2) that existing building operations is used: this suspension rod ground tackle comprises the anchor head parts and the head member that casts anchor; the used part of anchor head parts is the same up and down; they comprise bulb-end anchorage cup 21, nut 22, the ball-type backing plate 23 of protective cover 20, band stretch-draw connector, compositions such as sealing drum 24, pre-pipe laying 25, damper 26, bucker 27, suspension rod cable body 28.The deficiency that this technology exists is: one, the stretch-draw connector of the bulb-end anchorage cup of anchor head all has internal thread up and down, be connected with tension rod by screw thread within the stretch-draw connector of bulb-end anchorage cup, jack applies pulling force to tension rod, to adjust the depth of beam position, therefore the internal thread to the bulb-end anchorage cup will have higher requirement of strength, thereby make the external diameter of bulb-end anchorage cup just bigger, because the bulb-end anchorage cup must pass through pre-pipe laying when construction, make that the internal diameter of pre-pipe laying is bigger, and the internal diameter of pre-pipe laying weakens the intensity of bridge arch or beam greatly than senior general, in order to satisfy the requirement of strength of bridge arch, just must strengthen the diameter of bridge arch, increase the cost of bridge construction.Two, the internal thread of bulb-end anchorage cup will have certain length, makes that the length dimension of sealing drum is bigger, requires the length dimension of pre-pipe laying bigger, when the cross-sectional diameter of arch hour, pre-pipe laying and bucker will stretch out outside the arch, influence attractive in appearance.Three, the waterproof of bucker is not thorough, some the time water still can enter down anchor head, anchor head is corroded.
Three, technical scheme:
The technical problems to be solved in the utility model is: big, pre-pipe laying of bulb-end anchorage cup external diameter in the existing apparatus and sealing drum internal diameter are caused increasing bridging cost and the also not so good problem of anchor pole waterproof greatly.
For this reason, solution of the present utility model is: the one, the anchor cup of last anchor head or following anchor head is designed to not have tapped stretch-draw connector heading anchor slab form, and make its external diameter be dwindled to greatest extent, and then dwindle the internal diameter of pre-pipe laying; The 2nd, at the small end of bucker with near the suspension rod cable body outside of bucker, add thermal shrinkable sleeve, thoroughly anti-sealing enters anchor head.
Its concrete structure is: a kind of bulb-end anchorage suspension rod ground tackle; comprise in turn link to each other by last protective cover; the bulb-end anchorage cup; top nut; last ball-type cushion block; upper seal bore; go up pre-pipe laying; last damper; the last anchor head that last bucker constitutes; suspension rod cable body and by following bucker; following damper; following pre-pipe laying; the lower seal tube; following ball-type cushion block; lower nut connects; following bulb-end anchorage cup; the following anchor head that following protective cover constitutes; it is characterized in that: a bulb-end anchorage cup among described bulb-end anchorage cup or the following bulb-end anchorage cup for band stretch-draw connector; another one is a tack anchor cup, and thermal shrinkable sleeve reached thermal shrinkable sleeve down on the suspension rod cable body outside of the small end of bucker and close bucker respectively had under last bucker reaches.
The utility model advantage:
1. the utility model will go up anchor head or down the anchor cup of anchor head be designed to not have the heading anchor slab form of the stretch-draw connector of internal thread, because no longer stressed, make that its outer diameter D is dwindled to greatest extent, and then the inner diameter d of having dwindled pre-pipe laying, make the sectional dimension of bridge arch dwindle, reduce the cost of bridge construction.
2. since on the utility model or down the heading anchor slab for there not being the heading anchor slab of tapped stretch-draw connector, comparing its length dimension with the bulb-end anchorage cup of original tapped stretch-draw connector can significantly shorten, make the length dimension L of sealing drum significantly be shortened to 1,1 is approximately 3/5 of L, pre-pipe laying and bucker will can not stretch out outside the arch, make the handsome in appearance of whole bridge.
3. at the small end of bucker with near the suspension rod cable body outside of bucker, add thermal shrinkable sleeve, thoroughly anti-sealing enters anchor head, strengthens the antiseptic property of bulb-end anchorage suspension rod ground tackle.
Four, description of drawings:
Fig. 1: be the bulb-end anchorage Hanger Anchor of the utility model structure schematic diagram of signing an undertaking;
Fig. 2: the existing bulb-end anchorage Hanger Anchor structure schematic diagram of signing an undertaking.
Five, the specific embodiment:
Below, the technical characterictic to the utility model bulb-end anchorage suspension rod ground tackle is further described in conjunction with the accompanying drawings.
As shown in Figure 1: a kind of bulb-end anchorage suspension rod ground tackle; comprise in turn link to each other by last protective cover 1; bulb-end anchorage cup 2; top nut 3; last ball-type cushion block 4; upper seal bore 5; go up pre-pipe laying 6; last damper 7; the last anchor head that last bucker 8 constitutes; suspension rod cable body 9 and by following bucker 12; following damper 13; following pre-pipe laying 14; lower seal tube 15; following ball-type cushion block 16; lower nut connects 17; following bulb-end anchorage cup 18; the following anchor head that following protective cover 19 constitutes; the following bulb-end anchorage cup 18 of described anchor head down is the bulb-end anchorage cup of band stretch-draw connector; last bulb-end anchorage cup 2 is a tack anchor cup, and thermal shrinkable sleeve 10 reached thermal shrinkable sleeve 11 down on the suspension rod cable body outside of the small end of bucker 12 and close bucker respectively had under last bucker 8 reaches.
During construction, the heading anchor plate-end of suspension rod can be penetrated pre-pipe laying from bridge floor, will descend bulb-end anchorage cup end to penetrate the pre-pipe laying of beam then, install other part, stretch-draw under beam.
As a kind of conversion of the utility model embodiment, also bulb-end anchorage cup 2 on the last anchor head of this bulb-end anchorage suspension rod ground tackle can be made the bulb-end anchorage cup of band stretch-draw connector, and will descend the following bulb-end anchorage cup 18 of anchor head to make tack anchor cup.
