Description
Technical field
This utility model relates to a kind of charger, particularly relates to a kind of structural framing test vertical loading device.
Background technology
Structural test is an important channel of the mechanical property of research framework structure own, and the stressing conditions under phantom frame actual condition is to ensure that the effective Main Means of structural test data.But the in test loading insufficient space of framework, causes testing equipment bulk deposition in narrow space, the collection of the most inconvenient test data, on the other hand easily there is in test security incident.Simultaneously, horizontal displacement can be produced under by horizontal loads owing to loading equipemtn is fixed on test specimen on loading beam in loading, causing loading equipemtn to produce relative displacement with test specimen, vertical load reduces along with the increase of horizontal displacement, causes load(ing) point data acquisition inaccurate.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, proposes a kind of structural framing test vertical loading device.
In order to realize above-mentioned technical purpose, proposition techniques below scheme:
This utility model includes: assembly pulley, steel strand wires, and steel strand wires one end is connected with grade beam by connecting ring, and the other end is connected with bottle gouard moved by hands by assembly pulley, and bottle gouard moved by hands is connected with counterweight steel ingot.
Described steel strand wires are provided with pulling force sensor.
Described assembly pulley includes: the outer reaction frame fixed pulley of fixed pulley, grade beam fixed pulley, plane, described fixed pulley is fixed on test frame roof, and grade beam fixed pulley is fixedly mounted on grade beam；The outer reaction frame fixed pulley of plane and grade beam fixed pulley homonymy, reaction frame and test frame parallel placement, a certain distance is left in centre；The fixed installation of reaction frame lower end is perpendicular to test the reaction frame fixed pulley of frame plane, and the steel strand wires at test framework two ends are parallel with test frame column axis.
This utility model passes through assembly pulley and steel strand wires, is transferred to outside frame plane by the vertical load applying test framework, thus solves testing equipment and load the problems such as insufficient space on test framework, it is ensured that the safety that test loads.Vertical load is avoided to reduce along with the increase of horizontal displacement simultaneously as the test frame roof fixed pulley in assembly pulley links with test frame structure.
Described capital fixed pulley is for two kinds of forms of different tests Frame Design: a kind of frame beam column cross section is narrower, or post uses H profile steel or is assembled into the split cross section being similar to H profile steel cross section.Can use single pulley, pulley seat perforate is used for steel strand；Another kind of frame beam column cross section is wider, uses three fixed pulley isosceles triangle combining forms, and described frame roof fixed pulley is isosceles triangle fixed pulley group, the center distance of two pulleys in lower section be above pulley center to 3/2 times of lower section pulley center line distance.Keep fixing spacing ratio between each pulley thus ensure that same position payload values is equal.
Described manual calabash upper end is connected with steel strand wires, lower end is connected with balancing weight in loading procedure and balancing weight can all be mentioned applying balancing weight total weight on test specimen, it is also possible to is not mentioned completely by balancing weight and applies corresponding load according to the numerical value of the pulling force sensor being connected with steel strand wires.
Described steel strand wires and pulley contact position coating lubricating oil.

Detailed description of the invention
With example, this utility model is further illustrated below in conjunction with the accompanying drawings
As it is shown in figure 1, simply with the orientation in scheming, concrete implementation is described to describe, but assembling mode of the present utility model is not limited to the mode of Fig. 1, can use flexibly according to the concrete condition of test chamber.Install on the grade beam of the test framework lower left corner and connect ring 3(as shown in Fig. 5-Fig. 6) in order to be connected with steel strand wires 2, lower right corner fixed installation fixed pulley 4.Steel strand wires 2 are from the bottom up through the assembly pulley 1 on overtesting framework top, it is passed down through fixed pulley 4, being pulled upwardly and be connected with bottle gouard moved by hands 7 after the pulley 6 on reaction frame 11, bottle gouard moved by hands 7 chain hook is connected with counterweight 8, and test framework left and right steel strand wires must be parallel with framework itself.Pulling force sensor 9 is arranged on steel strand wires measurement pulling force numerical value.In each steel strand wires 2 and coating lubricating oil on each rubbing surface of pulley.
During loading, counterweight 8 is positioned over reaction frame 11 times, with bottle gouard moved by hands 7 pull-up slowly, stops when pulling force sensor reaches numerical value.Or, the weight of the vertical load half required in Selection experiment is all pulled away from ground as counterweight.For multipoint excitation, can many people simultaneously slowly multiple bottle gouard moved by hands of pull-up, it is also possible to take symmetric form, several times Slow loading.Guarantee that test framework occurs without the deformation being unfavorable for test owing to loading too fast and the asymmetric generation of load when adding vertical load.
The vertical load applied on test framework is 2 times of pulling force sensor display numerical value.
As in figure 2 it is shown, be the front view of test framework, Fig. 2 illustrates that this charger may be used on beam and capital loads.Test concrete loading scheme to arrange according to concrete testing program, be not limited to the loading scheme shown in Fig. 2.
Fig. 3-Fig. 4 is isosceles triangle assembly pulley compound mode, in order to ensure that under assembly pulley, each point stress is equal, need to ensure in figure, a represents that top pulley center is to lower section pulley center line distance, b represents the OC half of two pulleys in lower section, and a/b=3/4, assembly pulley should be symmetrical simultaneously.For preventing the highest unstability of assembly pulley, steel plate 12 such as Fig. 4 can be welded with in assembly pulley both sides.
Being that capital fixed pulley can use the fixed pulley as shown in Fig. 5-Fig. 6 for vertical uniform load q on the post that the webs such as H profile steel post or combination H type cross section are narrower, pulley seat is in the position perforation that steel wire passes.
Each fixed pulley in this utility model must fixing with each position be connected, and fixed pulley 4 fixed pulley 6 and connection ring 3 are main bearing member, it should meets its actual force request.
