Abstract

The invention discloses a kind of installation method of lasso protection cover, relate to construction engineering technical field, the protective jacket element of employing, is one section of half body that is provided with draw pin and tongue-and-groove at two junction surfaces, this half body is provided with internal layer, intermediate layer and skin, and intermediate layer is voided layer; Connection Step is first according to the needs of guy cable length, and protective jacket element is welded into a long semicanal one by one; The tongue-and-groove that again two long semicanal one sides' draw pin is inserted to the opposing party is fastened on drag-line outside; Then according to pipe length, the tongue-and-groove that two transparent half body one sides' draw pin is inserted to the opposing party is fastened on pipe outside, fastens successively one by one draw pin and the corresponding crimping of tongue-and-groove of the draw pin of transparent half body and tongue-and-groove and described half body; Finally the power line of Landscape Lamp is passed from the intermediate layer of long semicanal one end, pass from the other end, Landscape Lamp is placed in intermediate layer. It can solve existing protective sleeve of pulling cable installs the problem of Landscape Lamp difficulty.

Description

The installation method of lasso protection cover

Technical field

The present invention relates to construction engineering technical field, especially a kind of method of attachment of protective jacket of building guy cable.

Background technology

Building guy cable is the critical component being applied on architectural engineering, especially bridge structures, drag-line inside is steel wire, shaped by band colligation, pack into again high density polyethylene (HDPE) sheath, protective sleeve of pulling cable plays the antisepsis of hawser, the cross section profile of drag-line is circular, and pe sheath surface is comparatively smooth; Present stage protective sleeve of pulling cable installation, be that one section one section of sheath semicanal is welded to Len req, when welding, weld fused mass can be blocked intermediate layer, the intermediate layer of every section of semicanal can not intercommunication.

Along with the development in city, be arranged on various Landscape Lamps in city more and more, Landscape Lamp not only has the effect of illumination, more city beautify the landscape that has increased a lot of beauty; And each city, the view on bridge cable is peculiar especially, still, because the jacket surface outside bridge cable is comparatively smooth, Landscape Lamp difficulty is installed and even cannot installs, there are a lot of Landscape Lamps all can only be wrapped on sheath, be easy to through exposing to wind and rain impaired, moulding distortion.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of installation method of lasso protection cover, and it can solve the problem that existing stayed-cable bridge is difficult for installing Landscape Lamp on drag-line.

In order to address the above problem, the technical solution used in the present invention is: adopt a kind of protective jacket element, this protective jacket element is one section of half body that is provided with draw pin and tongue-and-groove at two junction surfaces, and this half body is provided with internal layer, intermediate layer and skin, and intermediate layer is voided layer;

Connect according to following steps:

A, according to the needs of guy cable length, protective jacket element is welded into a long semicanal one by one;

B, the tongue-and-groove that two described long semicanal one sides' draw pin is inserted to the opposing party are fastened on drag-line outside and form pipe;

C, according to described pipe length, the tongue-and-groove that two transparent half body one sides' draw pin is inserted to the opposing party is fastened on pipe outside, fasten successively one by one, transparent half inboard wall of tube body two ends bottom and middle part is that be provided with is crimped on the outer field outer wall of described pipe with boss central axes, draw pin and the corresponding crimping of tongue-and-groove of the draw pin of described transparent half body and tongue-and-groove and described half body;

D, the power line of Landscape Lamp is passed from the passage forming between the long semicanal of described protective jacket element and transparent half body, pass from the other end, Landscape Lamp is placed on wherein.

In technique scheme, scheme can also be more specifically: described transparent half tube wall longitudinal separation is inlaid with horizontal reflecting piece.

Further: described boss is provided with non-slipping block with the face of described outer phase crimping.

Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:

1, adopt buckle-type that hyaline layer is installed outward at protective jacket, between hyaline layer and Anti-slip cover, form passage, Landscape Lamp is placed in this passage, appears light by hyaline layer, and Landscape Lamp is not exposed to wind and rain, long service life, and moulding can not become, and installs simple and convenient.

2, because hyaline layer outer wall longitudinal separation is inlaid with horizontal reflecting piece, light get in reflecting piece, have reflective, the more aesthetic feelings of night scene increase of bridge.

Detailed description of the invention

Below in conjunction with accompanying drawing example, the invention will be further described:

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, one section, this lasso protection cover is provided with half body of draw pin 2 and tongue-and-groove 3 at two junction surfaces, this half body is provided with internal layer 1-1, intermediate layer 1-2 and outer 1-3, intermediate layer is voided layer; Multiple protective jacket elements are as shown in Figure 6 connected on drag-line, carry out according to following steps:

A, according to the needs of drag-line 10 length, protective jacket element is welded into a long semicanal one by one;

B, the tongue-and-groove 3 that two long semicanal one sides' draw pin 2 is inserted to the opposing party are fastened on drag-line 10 outsides and form pipes;

C, according to pipe length, the tongue-and-groove 7 that two transparent half body 4 one sides' draw pin 6 is inserted to the opposing party is fastened on pipe outside, fasten successively one by one, transparent half body 4 bottoms, inwall two ends and middle part boss 4-1 that be provided with and central axes are crimped on the outer wall of outer 1-3 of pipe, the non-slipping block 8 being provided with by boss face and the skin of half body are tightly affixed, and the draw pin 6 of transparent half body and tongue-and-groove 7 are corresponding side by side with draw pin 2 and the tongue-and-groove 3 of half body;

D, the power line of Landscape Lamp is passed from the passage 9 forming between the long semicanal of protective jacket element and transparent half body, pass from the other end, Landscape Lamp is placed on wherein.

As shown in Figure 1, transparent half tube wall longitudinal separation is inlaid with horizontal reflecting piece 5, and in the case of the lamp in certain section of protecting pipe goes wrong and do not work, its outer reflecting piece also can reflect car bulb or other light.

The installation method of this lasso protection cover and the installation of Landscape Lamp, simple and convenient, can after installing, drag-line carry out sheath installation, and the present invention can be used for the installation construction of new bridge, can be used for again maintenance and the replacing of old bridge protective sleeve of pulling cable.
