Abstract
The utility model discloses to a longspan expanding structure beam belonging to construction beam. The beam structure is connected by a plurality of intercrossed pull rods by bolts, and the upper of the beam structure is provided with an approach slab, while the lower is connected by a foldable pull rod, the loading capability of the beam is further improved, each connecting rod is provided with three to five connecting points, and the distance of two connecting points is not equal, and the height and span of the arc can be adjusted by the finished integration. The beam can be applicable to bridges and roof beams, and during wartime or flood disasters the beam in particular has special advantages of quickly installation, convenience, time saving, material saving, wide use and great social benefit and economic benefit.
Description
The utility model relates to the building girder construction, particularly a kind of large span stretching structure beam body that is mainly used in house and bridge construction.
As everyone knows, long-span beams body applied range, back timber such as indoor sport venue, movie theatre, bulk storage plant, aircraft repair factory building, overpass in the modern urban construction, all need the beam body of large span across the bridge of rivers, existing road bridge, the prefabricated template beam body of most of use rides on the thick bridge pier, and for about 30 meters bridge, the centre is wanted two big cement master piers of frame at least; Existing wideer slightly factory building, movie theatre, warehouse, indoor many principal post supporting top beams are arranged all, both taken up an area of face, and taken material again and also be in the way, the bridge of this class large span, must make whole back in advance installs, volume is big and weigh, and lifts very difficultly, and installation rate is slow, especially during the war years, for striving for the fight triumph, often need to set up in a short period of time the bridge of a large span, be difficult to meet the demands with traditional long span building mode.
The purpose of this utility model provides a kind of large span stretching structure beam body.Can draw in and extend after the assembling of this beam body, dome height can lifting, even can make the plane.Transportation and lift easyly can once lift and puts in place, both saves trouble, and saves time again, can reduce cost, and its span can surpass the length of traditional beam body, all is well suited for for permanent installation and provisional installation.
The purpose of this utility model is achieved in that a kind of large span stretching structure beam body, it is characterized in that: by the bolt block construction beam body that is formed by connecting, in the middle of the upper extreme point that per two connecting rods connect, accompany attachment strap by the many equidistant mutual intersections of connecting rod; Adjacent two end points couple together with pull bar in the bottom, and the two ends of beam body is fixed on the support.
The tie point of described equidistant cross one another connecting rod is 3-5, and distance does not wait between every connecting rod two contact.
The pull bar of described tie-beam body bottom adjacent both ends point is made up of two joints, and its middle part has movable axis to connect.
The fixing support in beam body two, described unit is bridge pier or house column.
The support of described clamped beam body also is equipped with the lifting gear of control arch face lifting.
The utility model is compared with prior art: for build bridge, build a house, the utility model lifts very convenient under rounding state, can once lift and put in place, overcome the segmental hoisting of prior art, volume is big, and installation rate is slow, shortcoming long in time limit, have save time, material-saving, save money, span can adjust at any time, particularly in the wartime or run into extraodinary flood disaster period, in very short time, build bridge, strive for triumph, the utility model occupies special advantage.
Below in conjunction with description of drawings the utility model is illustrated.
Fig. 1 is a large span stretching structure beam body schematic diagram.
Fig. 2 is the rounding state schematic diagram of Fig. 1.
Figure 1 shows that large span stretching structure beam body schematic diagram, have 3-5 bolt hole 3 on the connecting rod 2 of this beam body, and the distance between per two holes is unequal.A unit beam body is to penetrate bolt hole 3 by the cross one another connecting rod 2 usefulness bolts 4 of two rows, connects into double rhombus, forms expansion bracket, and it connects length and is decided by the beam body span that designs.Between two connecting rods 2 of each end points of expansion bracket top, accompany to take and pull 1, couple together, couple together with strengthening sheet 11 taking to pull between 1 middle part and the upper extreme point with bolt 4; Two end points adjacent in the bottom of expansion bracket couple together with folding pull rod 5, can strengthen the supporting capacity of arched frame face, and every folding pull rod 5 all is to be connected by pull bar movable axis 6 by two short section pull bars.Its two ends of beam body that are assembled into are fastened on the support 7 with screw 8 and nut 9 again, when this support 7 is bridge pier, then are assembled into the arch bridge of large span, and by the height that is installed in the bridge floor lifting gear 10 control bridge floors on the bridge pier.If support 7 is the house column, then form the back timber of Long Span Roof.
Figure 2 shows that the rounding state of long-span beams body, when lifting, it is little, easy to operate to take up room, and can settle at one go, fixes one earlier, as fulcrum, stretchs out the opposite again and just has been easy to.
