Abstract

The utility model discloses a foldable girder grillage which comprises girder grillage rod parts and connecting parts, wherein, rib rods is arranged on the girder grillage rod parts; a plurality of the girder grillage rod parts are connected with rib rods arranged on each girder grillage part through the connecting parts for forming a girder grillage structure; at least a part of the rib rods and the connecting parts form the foldable girder grillage rotating connection. Because a part of the rib rods and the connecting parts of the foldable girder grillage provided by the utility model form the foldable girder grillage rotating connection, when the assembled girder grillage needs to be packed and transported, the girder grillage only needs to be folded forcefully to mutually folding the girder grillage rod parts with the connecting parts. Thus, the space occupation by the girder grillage is greatly reduced so that the girder grillage is convenient for package and transportation; when transported to the destination, the girder grillage can restore only through rotating the girder grillage rod parts and the connecting parts; the series of operation is convenient, and needs little labor and time; and thus, the work efficiency can be greatly improved.

Description

Foldable truss

Technical field

The utility model relates to a kind of portable truss, especially Foldable cellular truss.

Background technique

Each quasi-truss of Chu Xianing mainly comprises truss member and link in the market, has floor on the truss member, and the floor that connects on each truss member by link between a plurality of truss members forms truss structure.This truss only needs link and truss member assembling are got final product when needs are taken dress, just need when needing to shift transportation again link and truss member to be split packing, again take dress when arriving the another location, in this process, be used to time of assembling and splitting comparatively, very expend man-hour.

Summary of the invention

Thereby technical problem to be solved in the utility model provide a kind of under assembling condition the collapsible foldable truss that shifts and pack be convenient to.

For this reason, the foldable truss that the utility model provides comprises truss member and link, have the rib bar on the truss member, the rib bar that connects on each truss member by link between a plurality of truss members forms truss structure, forms to small part rib bar and link and makes that truss is folding to be rotationally connected.

Truss is folding to be rotationally connected because the part rib bar of the foldable truss that the utility model provides and link formation make, so folded truss of when the truss that assembles need be packed and shift, only need exerting oneself, truss member and link are superimposed with each other, thereby significantly reduced the volume that truss takies, make it be convenient to packing and transfer more, only need rotate truss member and link when waiting to arrive the destination gets final product the truss reinstatement, these a series of operations are very convenient, artificial and the time that needs is also few, therefore can increase work efficiency greatly.

Description of drawings

The perspective view of the foldable truss that Fig. 1 provides for the utility model.

Fig. 2 be among Fig. 1 truss member end view drawing.

In each accompanying drawing: 1, truss member, 2, link, 3, the rib bar, 4, breach.

Embodiment

As Fig. 1, shown in Figure 2, comprise truss member 1 and link 2 among first kind of embodiment of the foldable truss that the utility model provides, link 2 generally is the butterfly sheet, have rib bar 3 on the truss member 1, the rib bar 3 that connects on each truss member 1 by link 2 between a plurality of truss members 1 forms truss structure, form to small part rib bar 3 and link 2 and to make that truss is folding to be rotationally connected, have axle sleeve and rotating shaft respectively on rib bar 3 that formation is rotationally connected and the link 2, the mutual socket of rotating shaft and axle sleeve, it is tabular one-body molded with main body that in the both sides of the chest bar 3 of truss member 1 one of them is, another rib bar 3 is the axle sleeve form with the joint of link 2, the cross section of axle sleeve is the arc shape that has breach 4, the opening of breach 4 distance less than with the diameter of the supporting rotating shaft of this axle sleeve, breach 4 can be used for the rotating shaft on the link 2 is snapped in the arc axle sleeve.

With reference to Fig. 1, shown in Figure 2, comprise truss member 1 and link 2 among second kind of embodiment of the foldable truss that the utility model provides, link 2 generally is the butterfly sheet, have rib bar 3 on the truss member 1, the rib bar 3 that connects on each truss member 1 by link 2 between a plurality of truss members 1 forms truss structure, part rib bar 3 and link 2 forms and makes that truss is folding to be rotationally connected, have rotating shaft and axle sleeve respectively on rib bar 3 that formation is rotationally connected and the link 2, the mutual socket of rotating shaft and axle sleeve, the cross section of axle sleeve is the arc shape that has breach 4, the opening of breach 4 distance less than with the diameter of the supporting rotating shaft of this axle sleeve, the existence of this breach 4 makes things convenient for rotating shaft to snap in the axle sleeve, wherein truss member 1 is provided with two rib bars 3, article two, the angle between the rib bar 3 becomes 90 degree, the rib bar 3 that link 2 connects on four truss members 1 forms four bar truss, two links 2 that are oppositely arranged form with rib bar 3 and are rotationally connected, remaining two links 2 form a fixed connection with rib bar 3, it is tabular one-body molded with main body that in the both sides of the chest bar 3 of this truss member 1 one of them is, and another rib bar 3 is the rotating shaft form with the joint of link 2.
