Abstract

A trapezoid steel roof truss with hollowed-out chord members comprises an upper roof truss chord member (1), a lower roof truss chord member (3), diagonal web members (5), vertical web members (6) and end web members (7). The upper roof truss chord member is connected on the lower roof truss chord member through the diagonal web members, the vertical web members and the end web members, the end web members are positioned at two ends between the upper roof truss chord member and the lower roof truss chord member, the vertical web members are vertical to the upper roof truss chord member and the lower roof truss chord member and uniformly distributed between the two ends of the upper roof truss chord member and the lower roof truss chord member, two of the diagonal web members are mounted between each two adjacent vertical web members, and one end of each diagonal web member is connected with the lower roof truss chord member on the lower portions of the vertical web members while the other end of each diagonal web member is connected with the upper roof truss chord member. The trapezoid steel roof truss with the hollowed-out chord members has the advantages that self weight of long-span steel-truss roofs of industrial factory buildings is reduced, and construction cost is saved as the trapezoid steel roof truss is 15% less than a traditional steel roof truss in steel consumption; the trapezoid steel roof truss is applicable to long-span steel roof truss structures of the industrial factory buildings for power plants, textile enterprises, iron and steel enterprises and the like.

Description

A kind of chord member hollow type trapezoidal steel roof truss
technical field
The utility model relates to a kind of chord member hollow type trapezoidal steel roof truss, belongs to wide span steel roof frame building structure technology field.
background technology
Along with the development of national national economy, very fast to the increase in demand of Long Span Industrial Factory Building, particularly power plant, weaving and iron and steel enterprise are more to the demand of Long Span Industrial Factory Building.
The wide span steel roof frame top-bottom chord of domestic industry factory building generally adopts the real abdomen member such as Two bors d's oeuveres angle steel, H shaped steel, steel roof truss is large with steel material, it is heavier to conduct oneself with dignity, be unfavorable for the stressed of steel roof truss self and supporting construction thereof, in the time that needs are considered vertical earthquake, steel roof truss deadweight is excessive more unfavorable to structure.
The deadweight problem that solves wide span steel roof frame member is the technical problem that structural engineering teacher faces.
summary of the invention
The purpose of this utility model is, the problem weighing very much according to the wide span steel roof frame member dead weight of existing industrial premises, and the utility model is released a kind of chord member hollow type trapezoidal steel roof truss.
The technical solution of the utility model is that a kind of chord member hollow type of the utility model trapezoidal steel roof truss is made up of upper chord of roof truss, roof truss lower chord, diagonal web member, perpendicular web member and end web member.Upper chord of roof truss is connected on roof truss lower chord by diagonal web member, perpendicular web member and end web member, the two ends of end web member between upper chord of roof truss and roof truss lower chord, erect web member perpendicular to upper chord of roof truss and roof truss lower chord, and be evenly distributed between upper chord of roof truss and the two ends of roof truss lower chord; Between adjacent two perpendicular web members, two diagonal web members are installed, diagonal web member one end connects the roof truss lower chord of perpendicular web member bottom, and one end connects upper chord of roof truss.
On the web of the upper chord of roof truss of described roof truss and roof truss lower chord H shaped steel chord member, be evenly distributed with at a certain distance hollow out circular hole; On the web of upper chord of roof truss, be evenly distributed with upper chord of roof truss hollow out circular hole, on the web of roof truss lower chord, be evenly distributed with roof truss lower chord hollow out circular hole.
Near connected node, hole adopts the wide steel plate of the thick 50mm of 10mm to strengthen hole.
Described hollow out Circularhole diameter is 20mm ~ 200mm.
The beneficial effects of the utility model are that the local hollow out of web of the H shaped steel chord member of upper chord of roof truss of the present utility model and roof truss lower chord, greatly reduces the deadweight on industrial premises large span steelframe roof, does not affect again the intensity on steelframe roof simultaneously.The comparable traditional steel roof truss saving steel consumption 15% of the present invention, saves construction costs.
The utility model is applicable to the wide span steel roof frame structure of the industrial premises such as power plant, weaving and iron and steel.
brief description of the drawings
Fig. 1 is the utility model chord member hollow type trapezoidal steel roof truss structural representation;
Picture in picture number: 1 is upper chord of roof truss; 2 is upper chord of roof truss hollow out circular hole; 3 is roof truss lower chord; 4 is roof truss lower chord hollow out circular hole; 5 is diagonal web member; 6 is perpendicular web member; 7 is end web member.
Detailed description of the invention
Detailed description of the invention of the present utility model as shown in Figure 1.
A kind of chord member hollow type of the present embodiment trapezoidal steel roof truss is made up of upper chord of roof truss 1, roof truss lower chord 3, diagonal web member 5, perpendicular web member 6 and end web member 7.Upper chord of roof truss is connected on roof truss lower chord by diagonal web member, perpendicular web member and end web member, the two ends of end web member between upper chord of roof truss and roof truss lower chord, erect web member perpendicular to upper chord of roof truss and roof truss lower chord, and be evenly distributed between upper chord of roof truss and the two ends of roof truss lower chord; Between adjacent two perpendicular web members, two diagonal web members are installed, diagonal web member one end connects the roof truss lower chord of perpendicular web member bottom, and one end connects upper chord of roof truss.
The long 50m of the present embodiment lower chord, hollow out Circularhole diameter is 50mm.
Described upper chord of roof truss 1 and roof truss lower chord 3, by local the web of H shaped steel chord member hollow out, hollow out circular hole 4 is evenly distributed on the web of upper chord of roof truss 1 and roof truss lower chord 3 every 200mm distance; Near connected node, hole adopts the wide steel plate of the thick 50mm of 10mm to strengthen (connected node refers to the position being connected of upper and lower string with the web member of roof truss) to hole.
Chord member needs the hole of hollow out made in the time of produce in factory, needs the hole of strengthening to adopt Plate Welding to strengthen, and remaining on-the-spot processing and fabricating method is with traditional steel roof truss.
