Abstract

The utility model discloses a high-span roofing space pipe truss structure for heavy industry, comprising a plurality of horizontal pipe trusses and vertical pipe trusses which are mutually connected. The high-span roofing space pipe truss structure is characterized in that the horizontal pipe trusses comprise horizontal upper chord pipes, horizontal lower chord pipes and a plurality of horizontal branch pipes, wherein each horizontal upper chord pipe comprises two steel pipes; each horizontal lower chord pipe is one steel pipe under the center of the two steel pipes forming one horizontal upper chord pipe; and the horizontal branch pipes are connected with the horizontal upper chord pipes and the horizontal lower chord pipes; and the vertical pipe trusses comprise vertical upper chord pipes, vertical lower chord pipes and a plurality of vertical branch pipes, wherein each vertical upper chord pipe and each vertical lower chord pipe are respectively one steel pipe, and the vertical branch pipes are connected with the vertical upper chord pipes and the vertical lower chord pipes. The high-span roofing space pipe truss structure is economical and practical, and has better social and economic benefits.

Description

A kind of heavy industry long-span roofing space tube truss structure

Technical field

The utility model belongs to the industrial construction field, relates to a kind of heavy industry long-span roofing form of structure, especially a kind of heavy industry long-span roofing space tube truss structure.

Background technology

At present, the roof structure form relates to multiplely in the industrial construction, mainly is divided into steel work and concrete structure two big classes.Concrete structure generally is prefabricated thin webbed girder structure, is fit to the factory building of 9 meters to 18 meters of spans; Steel work generally is triangle steel roof truss, trapezoidal steel roof truss, portal frame etc., wherein triangle steel roof truss, trapezoidal steel roof truss are fit to the factory building of 18 meters to 36 meters of spans, portal-rigid frames generally are applied in the light Steel-Structure Factory with Steel, triangle steel roof truss, trapezoidal steel roof truss etc. are the form of structure that present heavy industry factory building often adopts, but their common feature all belongs to the plane structure system.When the factory building span was big, concrete structure was not suitable for, as adopts above-mentioned steel roof truss form, and roof truss height and rod member size increase thereupon, and steel quantity consumption is very big, the cost height.

The utility model content

In order to overcome above-mentioned defective, technical problem to be solved in the utility model is to provide a kind of economical and practical heavy industry long-span roofing space tube truss structure.

For achieving the above object, technical solutions of the utility model are as follows:

Roofing space tube truss structure comprises the interconnected transverse pipe truss of some Pin and vertically manages truss, it is characterized in that: the transverse pipe truss is made up of the pipe that laterally winds up, horizontal lower chord tube and several athwartship legs, the pipe that laterally winds up is made up of 2 steel pipes, laterally lower chord tube is 1 steel pipe, be positioned at the central lower of 2 steel pipes of the pipe that laterally winds up, athwartship leg is connected with horizontal lower chord tube with the pipe that laterally winds up; Vertically the pipe truss is by the pipe that vertically winds up, vertically lower chord tube and several vertical arms are formed, vertically wind up pipe and vertically lower chord tube be 1 steel pipe, vertically arm is connected with vertically winding up to manage with vertical lower chord tube.

The utility model is applied in the large span heavy industry factory building roof structure, be particularly suitable for large-tonnage heavy-duty and factory building span greater than the large span mill construction more than the 50m, function of use when normally moving except satisfying crane requires, because space tube truss system integral rigidity and bending-twisting ability that the space is formed in length and breadth are big, the operating condition that more can adapt to the industrial premises complexity, with traditional roof truss structure contrast, the pipe trussed construction is saved the construction costs cost and is reached more than 20%, has good social and economic benefit.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

As shown in Figure 1, the utility model is according to technological requirement, and its factory building span is 56.05m, and roofing space tube truss structure comprises the interconnected transverse pipe truss 1 of some Pin and vertically manages truss 2.

Shown in Fig. 2,3 and 4, transverse pipe truss 1 is by the pipe 3 that laterally winds up, laterally lower chord tube 4 and several athwartship legs 5 are formed, and the pipe 3 of laterally winding up is made up of 2 steel pipes, employing pair sloping roof trusses, and the every steel pipe gradient is 1/15; Laterally lower chord tube 4 is 1 steel pipe, is positioned at the central lower of 2 steel pipes of the pipe 3 that laterally winds up; Laterally wind up pipe 3 with laterally be provided with athwartship leg 5 between the lower chord tube 4, and with pipe 3 and laterally lower chord tube 4 welding of laterally winding up, thereby the transverse pipe truss 1 of formation del is provided with 11 Pin transverse pipe truss 1 altogether.

Roof purline 8 is set on transverse pipe truss 1, is used for factory building roof is gone along with sb. to guard him the support of steel plate.

Every Pin transverse pipe truss 1 and hollow ball node 7 welding, ball node 7 is seated on the factory building column cap.

As shown in Figure 5, in the both sides of transverse pipe truss 1 and the skylight 4 roads be set respectively for 6 times vertically manage truss 2, vertically pipe truss 2 is single truss structure, form by the pipe 9 that vertically winds up, vertical lower chord tube 10 and several vertical arms 11, the pipe 9 that vertically winds up is 1 steel pipe with vertical lower chord tube 10, vertically arm 11 and pipe 9 and vertical lower chord tube 10 welding of vertically winding up.

Vertically the pipe 9 that vertically winds up of pipe truss 2 is managed 3 welding with laterally winding up of transverse pipe truss 1, vertically lower chord tube 10 and hollow ball node 7 welding.Thereby factory building roof has formed the space that can bear the large-tonnage heavy duty crane stable, large span and has managed truss stability structural system in length and breadth.

The utility model bar cross section has adopted the pipe cross section, in use can be according to technology and total figure arrangement requirement, determine factory building columns distance and span, the factory building span is generally to be advisable more than 45 meters, the crane tonnage can be unrestricted, calculate to determine the height of pipe truss and the caliber and the wall thickness of each chord member and arm by structural analysis, also can be according to the material situation of locality, change the pipe cross section into I-shaped, rectangle and square tube cross section.Arrange the size and the position in skylight by building and air-conditioning requirement.
