Abstract

The utility model relates to a novel vertical loading device. In the novel vertical loading device, circular holes with the diameter being the same with that of circular steel rods and provided with threads are arranged at two ends of a long shaft of an oval steel ring; both sides of a short shaft of the oval steel ring are respectively provided with a side circular hole; the short circular steel rods are horizontally over against the side circular holes on both sides of the oval steel ring; and the two circular steel rods are respectively arranged at the upper part and the lower part of the oval steel ring, and are over against the circular holes on both ends of the long shaft of the oval steel ring. The novel vertical loading device overcomes the defects that a hydraulic jack serving as the vertical loading device is not suitable to be fixed, and the test and research accuracy is affected. The novel vertical loading device is convenient to use and accurate to load, overcomes the defects when the hydraulic jack applies vertical load on the top of a structural test model, and has better application prospect in researching the structural performance under the interaction of vertical load and repeated horizontal load.

Description

A kind of novel vertical charger

Technical field

The utility model relates to a kind of charger, particularly a kind of novel vertical charger.

Background technology

Before the present utility model, in the building structure Study of Experiment Model, need the development test model sometimes in vertical load and the structural behaviour under the horizontal loading acting in conjunction repeatedly.At present generally produce the vertical load of a setting on the top of test model with hydraulic jack, the bottom of general hydraulic jack is connected with test model with roller bearing, and the top of hydraulic jack links to each other with reaction frame.But this device is under the effect of horizontal loading repeatedly, and this method that applies vertical load exists vertical load to change and hydraulic jack such as should not fix at problem, directly influences the accuracy of experimental study sometimes.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, design, a kind of novel vertical charger of exploitation.

The technical solution of the utility model is:

A kind of novel vertical charger, its major technique is characterised in that and has identical with the round steel bar, the screwed circular hole of diameter at the major axis two ends of oval steel loop, minor axis two sides at oval steel loop are respectively opened a mother rib lateral rotundum, short round steel bar level is at the mother rib lateral rotundum of oval steel loop both sides, two round steel bars are respectively at the upper and lower place of oval steel loop, all at the circular hole at oval steel loop major axis two ends.

Advantage of the present utility model and effect are a kind of novel vertical charger simple structure, easy to use, load accurately, solved and utilized hydraulic jack to withstand on structural test model top to apply the deficiency that vertical load exists, at the research vertical load with bigger application prospect is arranged aspect the structural behaviour under the horizontal loading acting in conjunction repeatedly.

Other advantage of the present utility model and effect will go on to say below.

Description of drawings

Fig. 1---the utility model structural principle synoptic diagram.

Each label is represented among the figure:

Round steel bar 1, oval steel loop 2, circular hole 3, mother rib lateral rotundum 4, short round steel bar 5.

Embodiment

As shown in Figure 1:

The utility model mainly is made of the two two all screwed round steel bars 1 of end and an oval steel loop 2.

Specifically:

Have diameter and round steel bar 1 identical, screwed circular hole 3 at the major axis two ends of oval steel loop 2, respectively open a mother rib lateral rotundum 4 in minor axis two sides of oval steel loop 2; Short round steel bar 5 horizontal positioned, at 4, two round steel bars 1 of mother rib lateral rotundum of oval steel loop 2 both sides respectively at the upper and lower place of oval steel loop 2, all at the circular hole 3 on the oval steel loop 2.

The explanation of the utility model application process:

One end (outer end) of two round steel bars 1 (omits among the figure with test model respectively, do not draw) upper and lower end fix, two round steel bar 1 other ends (the inner) penetrate the circular hole 3 on the oval steel loop 2 and are threaded, short round steel bar 5 inserts on the oval steel loop 2 in the mother rib lateral rotundum 4 from one (being the right side the figure) side (horizontal direction), rotation by short round steel bar 5, make oval steel loop 2 tensions and two fixing garden steel poles 1 of test model upper and lower end, thereby in the structural test model, produce changeless vertical load, reach vertical loading purposes.

Claims

1. novel vertical charger, it is characterized in that having identical with the round steel bar, the screwed circular hole of diameter at the major axis two ends of oval steel loop, minor axis two sides at oval steel loop are respectively opened a mother rib lateral rotundum, short round steel bar level is at the mother rib lateral rotundum of oval steel loop both sides, two round steel bars are respectively at the upper and lower place of oval steel loop, all at the circular hole at oval steel loop major axis two ends.
