Abstract

The utility model relates to a section steel lower chord truss type supporting lever with opening cold formed section steel upper chords and circular tube web members; the supporting lever comprises cold formed U-shaped or M-shaped upper chord members, square, circular or H-shaped lower chord members, and the circular tube web members which weld the upper chord members and the lower chord members with the lower parts adhered together tightly through that both ends are flattened; the supporting lever is characterized in that the circular tube web members connect the upper chord members and the lower chord members into truss purlins; the lower chords of the truss serve as supporting levers and are connected with girders, and the upper chords can serve as general purlins used to support house panels; and angle steel is also arranged between the adjacent trusses to laterally connect the lower chords and the upper chords. The supporting lever is applicable to factory prefabrication, can realize large-scale industrial production, realize industrialization and standardization, and improve economy.

Description

The opening cold-rolled forming section winds up, pipe web member, shaped steel lower edge truss-like support tie-rod

Technical field

The utility model relates to the steel truss that roofing supports, and relates to a kind of steel truss formula tie-rod that is used for the slingcart Roof system specifically.

Background technology

Traditional slingcart factory building generally adopts joist to add the way of cold-rolled forming section purlin or ratio-frequency welding H shaped steel purlin; Support the rigid support that then adopts angle steel usually; And the tie-rod between supporting generally adopts H shaped steel or pipe, is provided with respectively with roof purline; Overall steel using amount is bigger.

The utility model content

Technical problem to be solved in the utility model is to provide that a kind of opening cold-rolled forming section that is used for slingcart roof purline system winds up, pipe web member, shaped steel lower edge truss-like support tie-rod.

Technical problem to be solved in the utility model realizes by the following technical solutions,

A kind of opening cold-rolled forming section winds up, pipe web member, shaped steel lower edge truss-like support tie-rod, it is by the upper chord of clod wash U type or M type, the lower chord of square, circle or H type, towards flat upper chord and lower chord are pasted the pipe web member of pin weld seam welding by two ends, it is characterized in that: described pipe web member links together upper chord and lower chord becomes the truss purlin, the lower edge of this truss is connected with girder as supporting tie-rod, and it winds up and can be used as the general purlin that supports roof panel; Angle steel also is set with lower edge or wind up and do the connection of side direction between described adjacent truss.

Described upper chord is bent into identical shaped cross sectional shape by the steel plate one, with be connected as lower edge after, the two ends part that stretches out, described lower chord adopts square tube or pipe or H shaped steel, two ends are connected by connector with the middle part of girder H shaped steel, described upper chord stretches out after the part, is positioned at the top of girder, and going up between the shoulder of girder H shaped steel connects by the high bearing of frame.

Connector overhanging on described double lower chord two ends of doing tie-rod truss purlin and the girder H shaped steel links to each other with bolt.

In the utility model, according to the layout of considering tie-rod as the support arrangement needs of slingcart roofing, so not only reduce the structural steel amount fully, but also can ensure the rigid support of roofing, because the steel truss in the utility model is welded by the last lower chord and the pipe web member of steel, thereby be applicable to that batch production is prefabricated, and can realize large-scale industrial production, its cost has advantage more.

In addition, the height that the utility model truss-like supports tie-rod will effectively be utilized, owing to have a lot of spaces between the web member of each truss, the equipment installation of certain size can freely be walked between truss, has effectively saved interior net storey height.And because upper chord itself has cold-rolled forming section to constitute, its smooth upper chord plane can be connected with various roof panel, thereby has saved more investment.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, the truss purlin that the pipe web member 4 that opening cold-rolled forming section of the present utility model winds up, pipe web member, shaped steel lower edge truss-like support square tube, pipe or H shaped steel lower chord 3 that tie-rod 1 extends in parallel by elongate cold-rolled forming section upper chord 2, with upper chord 2 and many indentations are connected upper chord 2 and lower chord 3 with arranging connects and composes, wherein the two ends of pipe web member 4 adopt towards flat and upper chord 2 and lower chord 3 paste the welding of pin weld seams after, combine by being connected with the girder 5 of roofing.Wherein a part of lower edge truss is connected with girder 5 as supporting tie-rod, the double tie-rod of doing of remaining truss purlin of arrangement between the adjacent lower edge truss, and angle steel 6 also is installed between adjacent lower edge truss lower edge truss lateral support is connected.

As described in Figure 2, the lower edge truss comprises lower chord 3, cold-rolled forming section upper chord 2 and the pipe web member 4 of square tube type, the two ends of upper chord 2 stretch out a part of 21, the two ends of the lower chord 3 of square tube type contact with the middle part of the H shaped steel of girder 5, welding support 51 on the girder contact surface of H shaped steel, fixedly connected between support 51 and the lower chord 3 by bolt 8.Because upper chord 2 extends outward a part 21, the top that a part 21 that has more is takeed on the H of girder 5 shaped steel, on a part 21 of stretching out and the H shaped steel between the shoulder the high bearing of installing rack 22 fixedly connected.

As shown in Figure 3, the lower chord 3 of remaining truss purlin directly ride over two ends girder 5 H shaped steel on take on, sequence interval is arranged, by pasting the welding of pin weld seam.

As shown in Figure 4, between per three adjacent lower edge truss, middle middle part angle steel connector 31 of prefabricated welding in factory of placing the lower chord 3 of lower edge truss, angle steel connector 31 is made of steel disc, and have screw 32 in the above, each fixedly connected angle steel 7 at two end points places of two lower edge truss that do not have angle steel connector 31, in the middle of the other end of angle steel 7 just is fixed on by bolt 8 between the screw 32 of the angle steel connector 31 of lower edge truss, form right-angled intersection, strengthen the rigid support of roofing, improve the suspension load capacity of truss.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
