Abstract
The utility model relates to an endpoint node configuration of a belt gallery steel truss, which belongs to the field of industrial or civil steel buildings. The endpoint node configuration of the belt gallery steel truss comprises a rigid frame pier, and a short corbel extending from the side surface of the rigid frame pier, wherein the lower chord support of the belt gallery steel truss is supported on the short corbel; the upper chord of the belt gallery steel truss is connected with the top plate of the rigid frame pier through a top connection plate; a first horizontal long elliptical bolt hole is formed on the top connection plate; a first bolt passes through the first horizontal long elliptical bolt hole; and a second bolt passes through a second long elliptical bolt hole on the steel plate on the top of the short corbel and the lower chord support to connect the belt gallery steel truss and the rigid frame pier in a slide manner. The endpoint node configuration with the advantage of the prior sliding bearing can ensure a horizontal relative displacement between the belt gallery and the rigid frame pier, so that the belt gallery loads can be transmitted effectively without changing the force state of the rigid frame pier, and the lateral rigidity of the belt gallery is also increased. The endpoint node configuration has the advantages of simple structure, reliable force transmission and convenient construction.
Description
Technical field
The utility model relates to a kind of joint structure, relate in particular to a kind of when the belt porch steel truss is connected in the rigid-frame column side belt porch steel truss endpoint node structure of truss, it belongs to industry or civilian construction steel building field.
Technical background
When the belt porch steel truss is connected with rigid-frame column, if directly the belt porch steel truss is connected in the rigid-frame column top by the lower edge bearing, can guarantee that belt porch steel truss vertical load is directly delivered on the rigid-frame column, the wind load of belt porch side direction can only be born by two steel trusss and the girder steel that is connected in two steel trusss; Invar truss end montant is generally angle steel, and rigidity own is little, causes the belt porch lateral rigidity weak.If the belt porch steel truss is connected in the rigid-frame column side, utilize the big advantage of rigidity in the rigid frame plane, bear the side leading wind load of belt porch jointly by rigid frame, then be enough to solve the problem of belt porch lateral rigidity weakness.
The utility model content
The utility model is exactly in order to solve the problems of the technologies described above, and provide a kind of belt porch steel truss endpoint node to construct, purpose is to make it have the advantage of traditional sliding support, when guaranteeing belt porch load normal delivery, also strengthened the belt porch lateral rigidity, and simple structure, power transmission is reliable, easy construction.
In order to solve the problems of the technologies described above, the utility model is achieved in that belt porch steel truss endpoint node structure, comprise rigid-frame column, stretch out short bracket in the rigid-frame column side, the lower edge seat supports of belt porch steel truss is on short bracket, and the belt porch steel truss winds up and is connected with the rigid-frame column top board by the top junction plate; The level that leaves on the junction plate of top is to the first Long Circle bolt hole, first bolt passes level to the first Long Circle bolt hole, pass the second oval bolt hole and the lower edge bearing of short bracket top steel plate with second bolt, belt porch steel truss and rigid-frame column are slidingly connected.
Described top junction plate and rigid-frame column top board are welded to connect.
Advantage of the present utility model and effect are as follows:
The utility model guaranteed belt porch and rigid-frame column can the generation level to relative displacement, it has the advantage of traditional sliding support, the belt porch load is effectively transmitted, can not change the stress of rigid-frame column, also strengthened the belt porch lateral rigidity simultaneously, and simple structure, power transmission is reliable, easy construction.
Description of drawings
Fig. 1 is a lateral view of the present utility model.
Fig. 2 is a top plan of the present utility model.
Fig. 3 is a bottom plan view of the present utility model.
Among the figure, 1, short bracket; 2, lower edge bearing; 3, top junction plate; 4, rigid-frame column top board; 5, the first Long Circle bolt hole; 6, first bolt; 7, second bolt; 8, the second oval bolt hole; 9, rigid-frame column; 10, belt porch steel truss; 11, the belt porch steel truss winds up.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model structure is as follows: belt porch steel truss endpoint node structure, comprise rigid-frame column 9, stretch out short bracket 1 in rigid-frame column 9 sides, the lower edge bearing 2 of belt porch steel truss 10 is supported on the short bracket 1, and the belt porch steel truss winds up and 11 is connected with rigid-frame column top board 4 by top junction plate 3; The level that leaves on the top junction plate 3 is to the first Long Circle bolt hole 5, first bolt 6 passes level to the first Long Circle bolt hole 5, pass second oval bolt hole 8 and the lower edge bearing 2 of short bracket 1 top steel plate with second bolt 7, the top steel plate of short bracket 1 must not weld with belt porch steel truss lower edge bearing 2, belt porch steel truss 10 and rigid-frame column 9 are slidingly connected, and top junction plate 3 is welded to connect with rigid-frame column top board 4.
The first Long Circle bolt hole 5 and the second oval bolt hole 8 can make belt porch and rigid-frame column can the generation level it has the advantage of traditional sliding support to relative displacement, the belt porch load is effectively transmitted, can not change the stress of rigid-frame column, also strengthened the belt porch lateral rigidity simultaneously, and simple structure, power transmission is reliable, easy construction.
