Abstract
An arched corrugated steel roof with enhanced bearing capacity through stay cables comprises upright columns (5), longitudinal beams (4) at the top of each upright column, and an arched corrugated steel roof (1) disposed on the longitudinal beams (4). The arched corrugated steel roof is characterized in that oblique bars (2) are fixed between the upright columns (5) on both sides; transverse bars (9) are fixedly connected between the oblique bars (5) on both sides through nodes (11); and upper bars (10) fixed on the arched corrugated steel roof (1) are arranged on the nodes (11). The arched corrugated steel not only meets the requirements for appearance and function, but also has enhanced bearing capacity, thereby enlarging the application span length.
Description
Technical field
The utility model relates to properties of arched corrugated steel roof, is a kind of properties of arched corrugated steel roof that strengthens bearing capacity by drag-line specifically.
Background technology
Properties of arched corrugated steel roof is a kind of medium and small span arch form thin shell structures, is introduced into China in late nineteen eighties.Its forming process is: adopt special shaping machine set, earlier with thick be that the building color painted steel strip of 0.6～1.6mm is molded into the straight plate of T type or U type cross section, again straight plate is rolled into single corrugated arch, at last each single arch is connected in sequence by cap seaming machine along side.
That properties of arched corrugated steel roof has is in light weight, cost is low, handsome in appearance, be suitable for that span is big, water resistance good, construction is simple and characteristics such as speed is fast, successfully be used for medium and small span buildings such as warehouse, stadiums, commerce and trade market, workshop, Waiting Lounge, military installations at present, have extremely strong vitality and development prospect.
But on China northeast, Xinjiang and Hunan and other places, a lot of properties of arched corrugated steel roof collapse accidents take place in recent years.Tracing it to its cause, is because snow load is bigger on the one hand, has surpassed the supporting capacity of properties of arched corrugated steel roof itself.In addition, the bearing capacity of arch own is low also is wherein main cause.For this reason, " arch properties of arched corrugated steel roof steel roof structure tecnical regulations " (CECS 167:2004) span of properties of arched corrugated steel roof is clearly proposed should not be greater than 30m.
Stride in the construction work in that a lot of individual layers of reality are medium and small, its roofing span is greater than 30m, and its checking of bearing capacity can not meet the demands, and requires to adopt properties of arched corrugated steel roof because the combined factors of construction practical situation is considered still to have.
Summary of the invention
The utility model provides a kind of properties of arched corrugated steel roof by drag-line enhancing bearing capacity, and purpose is to strengthen the bearing capacity of ripple arch roof system and use span.
The described properties of arched corrugated steel roof that strengthens bearing capacity by drag-line, comprise the longeron on column, column top, the properties of arched corrugated steel roof on longeron of stopping over, it is characterized in that: be provided with oblique drawbar between two heel posts, connect cross-tie by the node that is connected with oblique drawbar, also be provided with upper connecting rod and properties of arched corrugated steel roof is fixed from node.
Middle part at oblique drawbar, cross-tie is provided with tightening device.
As a kind of embodiment, described oblique drawbar is connected with longeron.
Elongated shaped steel on described upper connecting rod and the properties of arched corrugated steel roof is fixed, and described elongated shaped steel is fixing by anchor clamps and roof system lock seaming.
Described elongated shaped steel is channel-section steel, i iron, angle steel or steel pipe.
Described oblique drawbar, cross-tie, upper connecting rod are reinforcing bar or wire rope.
The utility model has not only met architectural appearance and functional requirement, and the bearing capacity of properties of arched corrugated steel roof is improved, thereby reaches bearing capacity that strengthens properties of arched corrugated steel roof and the purpose of using span.
Description of drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram,
Fig. 2 is the partial enlarged drawing of roof system and upper connecting rod junction A among Fig. 1.
Among the figure: 1-properties of arched corrugated steel roof, 2-oblique drawbar, 3-tightening device, 4-longeron, 5-column, 6-anchor clamps, the elongated shaped steel of 7-, 8-bolt, 9-cross-tie, 10-upper connecting rod, 11-lock seaming.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the properties of arched corrugated steel roof that strengthens bearing capacity as described in as shown in Fig. 1,2 by drag-line, comprise the longeron 4 on column 5, column top, the properties of arched corrugated steel roof 1 on longeron 4 of stopping over, it is characterized in that: be provided with oblique drawbar 2 between two heel posts 5, connect cross-tie 9 by the node 11 that is connected with oblique drawbar 2, it is fixing with properties of arched corrugated steel roof 1 also to be provided with upper connecting rod 10 from node 11.Described column 5 adopts steel or reinforced concrete member with longeron 4.
Middle part at oblique drawbar 2, cross-tie 9 is provided with tightening device 3, as flower basket bolt etc.
Described oblique drawbar 2 is connected with longeron 4.Perhaps described oblique drawbar 2 is connected with column 5.
As seen from Figure 1, when tension oblique drawbar 2 and cross-tie 9, upper connecting rod 10 tensions will inevitably be stoped arch cover that the arching distortion outwards takes place, thereby strengthen its supporting capacity greatly.
As shown in Figure 2, elongated shaped steel 7 is fixed on described upper connecting rod 10 and the properties of arched corrugated steel roof 1, and described elongated shaped steel 7 is fixed by anchor clamps 6 with roof system lock seaming 11.Anchor clamps 6 have 8 pairs of lock seamings of bolt 11 to clamp and are connected and fixed with elongated shaped steel 7 welding or bolt.Described elongated shaped steel 7 is hot-rolled steel channel or i iron, angle steel, steel pipe etc.
