Abstract
The invention provides a splitting method of a basic unit of a honeycomb-shaped triangular conical mesh shell structure; when in splitting, first a unit to be split is determined; an upper chord ball and three lower chord balls which are connected with the upper chord ball form a triangular conical unit; then one adjacent upper chord ball and three web members form a triangular claw unit; finally, a whole honeycomb unit is changed into three triangular conical units and three triangular claw units; and similarly, the unit to be split is extended outwards, so that the three triangular claw units exist around any one triangular conical unit, and the three triangular conical units also exist around any one triangular claw unit. According to the method, a mesh shell is installed through units, so that the construction is more convenient and quicker.
Description
Technical field:
The invention belongs to a kind of Construction of Steel Structure method, particularly a kind of method for splitting of honeycomb type pyrometric cone latticed shell structure elementary cell.
Background technology:
At present, the characteristics such as the large span that latticed shell structure has because of itself, large space, profile novelty are widely used in the public venue.Latticed shell structure only is hollow ball and connecting rod because structure forms simply, mostly adopts when mounted the high altitude bulk method respectively ball and bar to be carried out lower edge, wind up and locate construction, and the junction is adopted welding again, can finish the installation of structure.But all connector arrangements are constructed when mounted, and construction certainly will reduce efficiency of construction when especially installing in the high-altitude, increases security risk.Honeycomb type net shell has some characteristics own simultaneously, if make good use of, and will be so that construction be easier, quick.
Summary of the invention:
Purpose of the present invention just is to provide a kind of method for splitting of honeycomb type pyrometric cone latticed shell structure elementary cell, and the method is carried out the construction that the net shell is installed with the unit, so that construction is easier, quick.
As above design, technical scheme of the present invention is: a kind of method for splitting of honeycomb type pyrometric cone latticed shell structure elementary cell, it is characterized in that: during fractionation, at first determine split cells, three lower edge balls that wind up ball and join are consisted of a pyrometric cone unit, then in adjacent wind up ball and a triangle pawl unit of three web members compositions, last, whole cellular unit becomes three pyrometric cone unit and three triangle pawl unit; Same reason, split cells make it to form any one pyrometric cone unit and have three triangle pawl unit on every side to external expansion, equally have three pyrometric cone unit around any one triangle pawl unit.
The present invention has following advantage and good effect:
1, the present invention is divided into a plurality of split cells with honeycomb type pyrometric cone structure, three lower edge balls that are about to wind up ball and join are decided to be a pyrometric cone unit, with adjacent wind up ball and triangle pawl unit of three web members compositions, because the pyrometric cone unit is stable, fastness is good, though and triangle pawl unit is incomplete triangular cone, can guarantee the stable of unit but when construction, only need fix in the web ends colligation, can satisfy the cellular installation method of structure in construction period fully.
2, honeycomb type pyrometric cone net shell is after fractionation, finished half lower chord, all prefabricated installation works of web member, approximately finish 60% assembly unit engineering quantity, and this some work amount has been affected by other factors less, can carry out in advance, the arrangement of construction organization is had adjusting, impetus.
3, the prefabricated of split cells can carry out in the fabricating yard, handled easily, and the assembly unit quality is easily controlled.
Description of drawings:
Fig. 1 is honeycomb type pyrometric cone latticed shell structure schematic diagram;
Fig. 2 is that the present invention splits the form schematic diagram.
The specific embodiment:
As shown in Figure 1: honeycomb type pyrometric cone structure combines mutually for the hexagon that winds up, hexagon of lower edge and six triangles, and wherein triangle and hexagon share on one side.Comprise 6 balls that wind up (1), 12 lower edge balls (2) in a honeycomb type, the projection of the ball that winds up is positioned at the triangle that the lower edge ball forms, and the ball that winds up is connected by web member (3) with triangle lower edge ball.
As shown in Figure 2: 4 is the pyrometric cone unit, and 5 is triangle pawl unit.At first definition comprises the pyrometric cone unit of wind up ball and three lower edge balls, three web members, three lower chords in net shell cellular unit, then in its three adjacent triangular cones, determine respectively only by the ball that winds up, three triangle pawl unit that web member forms, after splitting like this, the ball node of structure and a part of rod member all are included in these two kinds of unit.
The pyrometric cone unit is the triangular cone, the unit is stable, and fastness is good, though triangle pawl unit is incomplete triangular cone, but when construction, only need fix in the web ends colligation and can guarantee the stable of unit, can satisfy the cellular installation method of structure in construction period fully.
Honeycomb type pyrometric cone net shell is after fractionation, finished half lower chord, all prefabricated installation works of web member, approximately finish 60% assembly unit engineering quantity, and this some work amount has been affected by other factors less, can carry out in advance, the arrangement of construction organization is had adjusting, impetus.Carrying out built in the fabricating yard in advance of unit, handled easily, the assembly unit quality is easily controlled.
