a positioning plate for fixedly supporting the main rod A is arranged on the positioning upright column, and the main rod A is placed on the positioning plate so that the main rod A is overlapped with a projection line of the main rod A on the steel plate;
the web members are fixed to the main bar a, the main bar B, and the main bar C.
The beneficial effects of the invention on one hand are as follows: the method can accurately position the spatial position of the truss rod piece, thereby achieving the purpose of quickly assembling the triangular truss, particularly the spatial twisted variable-section triangular truss.
Drawings
Fig. 1 is a front view in the process of assembling a triangular truss according to an embodiment of the present invention.
Fig. 2 is a plan view during an assembly process of a triangular truss according to an embodiment of the present invention.
Detailed Description
The invention is described in further detail below with reference to the figures and the detailed description.
The triangular truss assembling device comprises a steel plate 1, a baffle plate 2, a plumb bob 3, a positioning upright post 4 with scales, a positioning plate 5, a jack 13, a baking gun 14 and the like.
The method for assembling the triangular truss by using the assembling device of the triangular truss of the embodiment comprises the following steps:
and (4) leveling the field, horizontally placing the steel plate 1 on the ground, and adjusting by using a level gauge to ensure that the steel plate 1 is on the horizontal plane.
And bending and molding the main rod A9, the main rod B10 and the main rod C11 according to the drawing size.
The main bar B10 and the main bar C11 are fixed to the steel plate 1.
According to the cross section of the truss, the distance from the main rod A9 projected to the main rods B10 and C11 is determined, and a projection line 12 of the main rod A9 on the steel plate 1 is drawn.
And respectively fixing a plurality of positioning upright posts 4 with scales on projection points of each node of the main rod A9 on the steel plate 1, wherein the positions of the nodes are determined according to a drawing.
A positioning plate 5 for supporting a main rod A9 is arranged on a positioning upright post 4, the main rod A9 is placed on the positioning plate 5, the main rod A9 is overlapped with a projection line 12 of the main rod A9 on a steel plate 1, and the distance from the main rod A9 to the steel plate 1 can be determined according to a truss section diagram.
The web members are fixed to the main bar A9, the main bar B10, and the main bar C11, and include a web member a 6, a web member B7, and a web member C8, as shown in fig. 1.
Wherein the main bar B10 and the main bar C11 may be fixed on the steel plate 1 by: lofting the main rods B10 and C11 on the steel plate 1, and respectively drawing the radian sizes of the main rods on the steel plate 1; then, the main rod B10 and the main rod C11 are placed at the positions where lofting is performed on the steel plate 1 in advance and are fixed by the baffles 2, for example, the baffles 2 are positioned at the two sides of the main rod B10 and the main rod C11; the part (such as the position of each node) needing fine adjustment is tightly jacked by a jack 13, a baking gun is used for baking and bending the steel pipe, and the bending degree of the main rod B10 and the main rod C11 is slightly adjusted until the main rod B10 and the main rod C11 are respectively superposed with the corresponding lofting lines.
Wherein, can judge whether the king post A9 overlaps with its projection lines 12 through the plumb bob 3, to needing the part of fine setting (for example the position of each node) with jack 13 top-up, and the baking gun is heated and is buckled king post A9, adjust the crookedness slightly, until the tip of plumb bob 3 contacts the projection lines 12 of king post A9.
The innovation points of the invention are as follows: the vertical rod with the scales and the plumb bob can position the space position of the truss rod piece up, down, left and right, thereby achieving the purpose of quickly assembling the triangular truss, in particular to the space-distorted variable-section triangular truss. Through the projection of mobile jib and the location of taking the location stand and the plumb bob of scale, the radian of roast rifle of jack cooperation fine setting mobile jib is heated fire in addition, can solve the problem of space member quick positioning, accurate location fast.
