Abstract
The utility model relates to a compound anchoring device for prestressing force tensioning fiber reinforced ribs, which is characterized in that an annular positioning plate and a hollow screw rod are connected together inside and outside by a sleeve cylinder with a grouting hole through screw threads to form a compound anchoring system which can be sectionally filled with different gelling materials. The compound anchoring device for prestressing force tensioning fiber reinforced ribs can conduct rapid and reliable anchorage for the prestressing force tensioning fiber reinforced ribs.
Description
The utility model relates to a kind of device that utilizes two kinds of dissimilar cementitious material the prestressed stretch-draw fiber reinforced rebar in the civil works to be carried out compound anchoring.
Glass fiber bundle, aromatic polyamide fibre bundle and carbon fiber bar bundle etc. are handled the formed fiber reinforced rebar in back through sufficient resin impregnation, can be used as stretch-draw material in the prestressed structure engineering to substitute common high-strength steel because of it has lightweight, many characteristics such as high-strength, corrosion-resistant.Because fiber reinforced rebar can not position or anchoring by means such as screw thread, heading and wedge type anchor clamps as reinforcing bar when implementing prestressed stretch-draw, therefore, the anchoring of the prestressed stretch-draw fiber reinforced rebar in the existing experiment normally adopts as shown in Figure 1 with resin the prestressed stretch-draw fiber is increased the method that muscle is adhesively fixed and with concrete block the prestressed stretch-draw fiber reinforced rebar bonded fixing method as shown in Figure 2.Prestressed stretch-draw fiber reinforced rebar (10) among Fig. 1 is adhesively fixed on wedge tool (13) by resin (8); Prestressed stretch-draw fiber reinforced rebar (10) among Fig. 2 is to bond fixing by the concrete block (15) that reinforced by reinforcing bar (14).But, though the mode that the prestressed stretch-draw fiber reinforced rebar is adhesively fixed with resin can utilize the fast rigid and high adhesiveness of resin guarantee to test easy, promptly carry out, but because resin lacks the reliability of adhesive strength at a specified future date, therefore, from the life requirement of works, this method should not be applied directly in the actual engineering structures and go.Simultaneously, though bonding fixing method with concrete block can utilize concrete to bond performance reliably the prestressed stretch-draw fiber reinforced rebar is carried out semi-permanent safe anchoring, but make concrete block at the construction field (site) and need and wait for the long required length of time of concrete through many miscellaneous block forming operations, and, stressed location between building block after the moulding and the processed structural element also needs the intermediary of other supplementary means, therefore, to directly apply to actual engineering structures also be unpractical to this method.
The purpose of this utility model is the anchor device that a kind of prestressed stretch-draw fiber reinforced rebar of practicability will be provided, and it can utilize the both convenient and long-term safety of two kinds of dissimilar cementitious material reliably the prestressed stretch-draw fiber reinforced rebar to be carried out directly effective compound anchoring.
The utility model is achieved in that at a band grout hole and has externally threaded sleeve two ends and establishes one respectively and wear muscle hole and bolt apertures, have the ring-type location-plate of internal thread with the external screw thread of sleeve contact one, have externally threaded cored screw with the bolt apertures contact one of sleeve.When the prestressed stretch-draw fiber reinforced rebar is implemented stretch-draw, earlier with resin being adhesively fixed in cored screw from wearing the prestressed stretch-draw fiber reinforced rebar that the muscle hole penetrates.When stretch-draw finishes, directly screw the ring-type location-plate on the sleeve.Then, inject cement mortar by the grout hole on the sleeve in sleeve and further the prestressed stretch-draw fiber reinforced rebar is bonded fixingly, so far, the purpose of this utility model is all reached.
The utility model makes the anchoring gimmick of the prestressed stretch-draw fiber reinforced rebar in the existing experimental stage move towards practicality with the form of simple mechanism.And, because the utility model has been taked the technology of compound anchoring, thus with the existing experimental stage in resin the method that the prestressed stretch-draw fiber reinforced rebar is adhesively fixed is compared, increased the reliability of long-term safety anchoring.Simultaneously, and with concrete block the prestressed stretch-draw fiber reinforced rebar is bonded fixing method in the existing experimental stage and compares, save miscellaneous building block field fabrication operation and need not to wait for reach concrete require the length of time must process long period.
Below accompanying drawing is carried out simple declaration.Fig. 1, Fig. 2 are the signals of prior art situation.Fig. 3 is structure signal of the present utility model.Fig. 4 is operating principle signal of the present utility model.Fig. 5 is the performance signal of the utility model embodiment 1.
Below, the drawing below 3 comes the utility model and embodiment are specified in conjunction with the accompanying drawings.Fig. 3 is structure of the present utility model signal: have grout hole (1) and wear muscle hole (2) and the sleeve (4) of bolt apertures (3), ring-type location-plate (5), cored screw (6), they connect according to aforementioned realization explanatory note of the present utility model by screw thread (16), screw thread (17), form a sectional and inject two kinds of dissimilar cementitious material is carried out the segmentation anchoring to the prestressed stretch-draw fiber reinforced rebar compound anchor systems.Fig. 4 is operating principle of the present utility model signal: compound anchor device (7) utilizes resin (8) and these two kinds of dissimilar cementitious material of cement mortar (9) to realize compound anchoring to prestressed stretch-draw fiber reinforced rebar (10).
Embodiment 1: as shown in Figure 5, the two ends that compound anchor device (7) utilizes resin (8) will be located in the prestressed stretch-draw fiber reinforced rebar (10) in the bellows (11) are adhesively fixed in cored screw (6), and utilize the cement mortar of injecting in the sleeve (4) (9) to implement further to bond fixing to prestressed stretch-draw fiber reinforced rebar (10).Simultaneously, by the stressed location of ring-type location-plate (5), compound anchor device (7) is fixed on prestressed stretch-draw fiber reinforced rebar (10) force part of processed pre-stressed structural member (12).
The 1-hole of being in the milk, 2-wears the muscle hole, the 3-bolt apertures, the 4-sleeve, 5-ring-type location-plate, the hollow screw rod of 6-, 7-compound anchor fixing apparatus, 8-resin, the 9-cement mortar, 10-prestressed stretch-draw fiber reinforced rebar, The 11-bellows, the processed pre-stressed structural member of 12-, 13-wedge Tool, 14-reinforcing bar, the building block of 15-concrete, 16, the 17-screw thread.
Claims (1)
1. the compound anchor device of a prestressed stretch-draw fiber reinforced rebar that is made of sleeve (4), ring-type location-plate (5), cored screw (6), the sleeve (4) that it is characterized in that having grout hole (1) is tied ring-type location-plate (5) and cored screw (6) internal and external antithetical couplet by screw thread (16), (17) and forms the compound anchor system that a sectional injects different cementitious material.
