Description

[Detailed explanation of the invention] This invention is suitable for assembling heavy temporary structures for the entry of transport vehicles and heavy machinery, such as truck entry berths or trotsko piers, using steel frames such as H-shaped steel piles and angles. This relates to assembly fittings for heavy temporary pedestals used, and is particularly provided for joining angles as horizontal braces to the flange end faces of steel piles.

Next, the assembly fitting of this invention will be explained in detail based on the drawings of the embodiments.

1 to 3 are a perspective view, a front view, and a side view of an assembly fitting for a heavy temporary gantry according to a first embodiment of the present invention.

1 is a metal fitting main body, and 2 is a holding part having a vertical holding groove 3 in a base piece 1a at the proximal end of this metal fitting main body 1, and facing inward from the left and right outer sides on a common axis a-a. Female threaded portions 4, 4 are provided.

Reference numerals 5 and 5 indicate clamping bolts that are screwed into the female threads 4 and 4 and tightened against the flanges of the steel pile A housed in the clamping part 2. When using high tension bolts with tip projections, Can be tightened strongly with effective biting force.

Reference numeral 6 denotes a clamping groove opened in the horizontal direction in the arm piece 1b at the tip of the metal fitting main body 1 at the horizontal axes that intersect with each other at an appropriate interval (l dimension) downward from the axes of the clamping bolts 5, 5 on the proximal end side. 7. This is the tip-side clamping portion having a diameter of 7.

Reference numerals 8 and 8 indicate internally threaded portions located above and below the clamping portion 6 of the distal end portion and provided on a common axis bb perpendicular to the axis aa of the clamping bolts 5, 5; This is a clamping bolt that is screwed into the internally threaded parts 7, 7 and tightened facing the flange of the angle L housed in the clamping part 6. Like the clamping bolts 5, 5 on the proximal end side, it is a high tension bolt with a protrusion at the tip. If a bolt is used, it can be strongly tightened with effective biting force against the steel material.

When using the assembly fitting of this invention with the above structure, as shown in Figs. Fit the clamping groove 3 and tighten the clamping bolts 5, 5 from the left and right with a specified tightening torque to fix the metal fitting, and in this state insert the flange L1 of the angle L into the clamping part 6 on the tip side of the metal fitting main body 1. It is housed horizontally and joined by tightening the clamping bolts 9, 9 from above and below with a predetermined tightening torque.

The angle of this angle L with respect to the steel pile A is the fifth
As shown in the figure, it can be installed at right angles or in a certain range of angles.

The assembly fitting of this first embodiment is not only a combination of H-shaped steel and L-shaped steel as described above, but also
It can also be applied to joining H-shaped steel and channel steel.

FIG. 6 is a plan view of the second embodiment, and when protruding the arm piece 1b on the distal end side of the metal fitting main body 1, its angle is set in a plane with respect to the axis a-a of the proximal side clamping bolts 5, 5. By swinging an appropriate angle θ from the right angle direction and making the position of the clamping part 6 on the tip side perpendicular to the axis a-a of the clamping bolts 5, 5 on the proximal side as described above, and eccentrically as appropriate, the steel frame pile can be formed. The mounting angle of angle L relative to A can be made larger,
The protruding length of one arm is also relatively short.

In each of the above-mentioned embodiments of this invention, clamping bolts 5, 5 and 9, 9 facing each other on a common axis are provided in the clamping parts 3 and 6, respectively, but it is possible to remove one of the clamping bolts. Similar effects can be obtained when a receiving surface 10 with a tip projection is provided at that location (FIG. 7).

Since the assembly fittings of this invention are constructed and used as described above, there is no danger compared to welding or bolted connections, and quality control can be performed accurately by tightening with a constant tightening torque. Labor saving,
Rationalization is realized.

Furthermore, during dismantling, there is no loss of material at the end of the steel material, and there is no fear of cross-sectional damage to the steel material, making it economical.

Particularly, according to the assembly fitting of this invention, it is possible to widen the mounting angle of the horizontal brace by an angle or the like with respect to the steel frame pile, which has the effect of widening the range of use of the horizontal brace.

In addition, it is easy to construct and handle, so it is useful in practice.
