Problems solved by technology

Generally speaking, since the bolts are connected under pressure to the plate and rod-shaped members, in order to ensure the design strength, the position and diameter of the bolt holes opened in the plate and rod-shaped members need to be processed with high precision. Since multiple sets of bolt holes of the plate and bar-shaped members are aligned with each other, there is a problem in terms of assembly workability

[0037] figure 1 It shows the completed state of the joint of the first embodiment of the present invention. This joint is used to connect the rod-shaped member 11 a and the rod-shaped member 11 b divided along the virtual dividing plane 1 . Since the structure of the joint is plane-symmetrical with respect to the dividing surface 1, in the following description, unless otherwise specified, the rod-shaped member 11a side of the dividing surface 1 will be described, and the description of the rod-shaped member 11b side will be omitted. illustrate. In addition, by replacing the reference sign a with the reference sign b, the description on the rod-shaped member 11a side can be reread as the description on the rod-shaped member 11b side.

[0038] A step 21 a and a step 22 a are respectively provided at an end portion of the rod-shaped member 11 a on the side of the dividing plane 1 , and the connection member 31 engages with the steps. The connecting member 31 has an engaging p...

[0054] Below, use Figure 5 A second embodiment of the present invention will be described. Figure 5 is an enlarged view of a rod-shaped member having a step according to a second embodiment of the present invention. The second embodiment differs from the first embodiment in the positions of the steps 21a, 22a and the welding method of the steps 21a, 22a. The steps 21a, 22a are provided at positions spaced a small distance from the ends of the rod-shaped member 11a. Thus, overlay welds are used at weld lines 41a, 42a, 47a, 48a and edge welds are used at weld lines 43a, 46a. In this structure, by using the distance from the welding lines 47a, 48a to the end of the rod-shaped member 11a as a margin for adjustment, even if the longitudinal dimensional accuracy of the rod-shaped member 11a is not high, the structure of the present invention can be realized.

[0056] use Figure 6 A third embodiment of the present invention will be described. Figure 6 is an enlarged view of a rod-shaped member with a step according to a third embodiment of the present invention. The third embodiment differs from the first embodiment in the positions of the steps 21a, 22a and the joining structure of the steps 21a, 22a. In the third embodiment, the steps 21a, 22a are respectively arranged on the front ends of the flat plates 12a, 13a on the side of the dividing plane 1, and the welding lines 41a, 42a are welded by overlay welding, while the welding lines 49a, 52a are edge welded. , and butt welding is used at welding lines 50a, 51a. At this time, the surfaces of the steps 21a, 22a near the welding lines 50a, 51a and the surfaces of the flat plates 12a, 13a are located on the same plane. In this joining structure, since there is no weld seam on the split surface 1 side, the steps 21a, 22a can be brought closer to the split surface 1, thereby short...

Abstract

The invention provides a stretching joint of a truss structure, which has excellent assembling operability and can bear high load. The joint structure of the invention is obtained through connecting rod-shaped components on which an extending load is applied through connecting components. The joint structure is characterized in that: the rod-shaped components which are interconnected respectively have a step; each step has a snapping surface which is snapped with the connecting component; each connecting component has a snapping surface which contacts with the snapping surface of the step; through the snapping surfaces of the connecting components, the steps of the rod-shaped components which are interconnected are clamped for snapping with the step; and furthermore on condition that the stretching load is applied, the rod-shaped components comprising the step are separated from one another.

Description

technical field [0001] The present invention relates to a joint structure, a passenger conveying device with the joint structure and an installation method for the passenger conveying device, in particular to a joint structure of a bar-shaped member with good assembly workability and high load bearing capacity, and a passenger conveying device with the joint structure Equipment and its method of installation. Background technique [0002] A truss structure or a structure similar to a truss structure is used in general escalators, moving passages, cranes, and some bridges, in which a plurality of rod-shaped members are joined and assembled. That is, the axial force in the tensile direction or the compressive direction dominates the load acting on the rod-shaped member. [0003] However, since the above-mentioned products are all large-scale products, they need to be separated into multiple parts and transported to the installation site, where the parts are assembled. The jo...
