Abstract
The utility model relates to a prestressing external anchoring device which comprises a protective cover 1, a work clamping piece 2, a work anchor plate 3, an anchor plate 4, a spiral bar 5, a preembedded pipe 9 and a protective sleeve pipe 10, wherein an inner cavity of the anchor plate 4 is provided with an isolating sleeve 6 whose shape is similar to the shape of the inner cavity of the anchor plate 4, and the isolating sleeve is made of rubber or other plastic. The prestressing external anchoring device of the utility model has the advantages of lower manufacturing cost, easy construction and simple maintenance, and cables can be changed.
Description
The utility model relates to a kind of prestressing force external tendon ground tackle.
The prestressing force external tendon is a kind of easy to maintenance, prestress anchorage cable that can change rope, just begins starting at present in China, and existing prestressing force external tendon ground tackle mainly contains two kinds of forms:
First kind of form adopts the anchor head resemble like the drag-line form as shown in Figure 1, and it mainly has problems is that cost is very high, and constructional difficulties, reserving hole channel are bigger, weaken bigger to structural strength.
Second kind of form as shown in Figure 2, the problem that it mainly exists is to change rope, maintenance difficulty does not reach the real purpose of prestressing force external tendon---easy to maintenance, can change rope.
The purpose of this utility model be to provide a kind of safe and reliable, cost is lower, can change rope, safeguard simple prestressing force external tendon ground tackle.
For reaching above-mentioned purpose, solution of the present utility model is: the prestressing force external tendon ground tackle to existing second kind of form improves, and at the anchor plate inner chamber one deck TR thin rubber separation sleeve is set, and is used to isolate anchor plate and cement mortar; When changing rope, cut-outs of can keeping vegetarian in the middle of the rope prestressing tendon and be rolled in cement mortar on the rope from the taking-up of anchor plate two ends, reaches the purpose of changing rope.
Its concrete structure is: this prestressing force external tendon ground tackle comprises protective cover, work clip sheet, work anchor slab, anchor plate, spiral bar, pre-pipe laying 9, protective casing 10, it is characterized in that: at the anchor plate inner chamber separation sleeve similar to the anchor plate cavity shape arranged.
Owing to adopt said structure, the utlity model has cost lower, can change rope, easy construction, safeguard simple advantage.
Below, the architectural feature to the prestressing force external tendon ground tackle of the utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1, Fig. 2: existing prestressing force external tendon ground tackle structural representation.
Fig. 3: the prestressing force external tendon ground tackle structural representation of the utility model.
Embodiment
A kind of prestressing force external tendon ground tackle.As shown in Figure 3; this ground tackle comprises: protective cover 1, work clip sheet 2, work anchor slab 3, anchor plate 4, spiral bar 5, pre-pipe laying 9, protective casing 10; at anchor plate 4 inner chambers the separation sleeve 6 similar to anchor plate 4 cavity shapes arranged, these separation sleeve 6 materials are rubber or other plastic material.
Use implementation step: earlier anchor plate 4, spiral bar 5 and pre-pipe laying 9 installation in position; poured into a mould concrete component; treat that concrete component solidifies good back separation sleeve 6 is installed earlier in anchor plate 4; load onto protective casing 10; wear prestressing tendon 8 again; install work anchor slab 3, work clip sheet 2, pretension, stretch-draw.Stretch-draw is back cement injection mortar 7 in the duct well, covers protective cover 1, and the perfusion anticorrosive packing carries out anticorrosion to work clip sheet 2, work anchor slab 3.
Owing to promptly 8 antisepsises of prestressing tendon, 7 pairs of prestressing tendons 8 of while cement mortar are had bond stress again after cement mortar 7 is solidified, the dynamic load of prestressing tendon 8 can pass to separation sleeve 6 by cement mortar 7, pass to anchor plate 4 by separation sleeve 6 again, pass to concrete component again, improve the stress of prestressed anchor work clip sheet so greatly, improve the safety reliability of ground tackle.
Claims (2)
1, a kind of prestressing force external tendon ground tackle; comprise protective cover (1), work clip sheet (2), work anchor slab (3), anchor plate (4), spiral bar (5), pre-pipe laying (9), protective casing (10), it is characterized in that: the separation sleeve (6) similar to anchor plate (4) cavity shape arranged at anchor plate (4) inner chamber.
2, prestressing force external tendon ground tackle as claimed in claim 1 is characterized in that: described separation sleeve (6) material is rubber or other plastics.
