Abstract

The utility model relates to an adjustable form shore comprising an upper supporting column 2, a lower supporting column 9 and a thread sleeve 5, wherein, the ends of the upper supporting column and the lower supporting column are respectively provided with an upper base 1 and a lower base 10. A row of longitudinal eyelets 3 is arranged in the upper supporting column 2, and the upper part of the lower supporting column 9 is provided with a thread segment 8. The thread segment 8 is engaged with the thread sleeve 5, and a handle 6 is arranged on the thread sleeve 5. A stop bolt 4 on the thread sleeve 5 is inserted into the eyelets 3 after the stop bolt passes through a slot 7 on the thread segment 8. The utility model has the advantages that large quantity of wood is saved, the installation and the adjustment is rapid and convenient, man-hour is saved and no master mechanics is needed.

Description

Adjustable formwork pillar

The utility model relates to construction equipment, especially a kind of adjustable formwork pillar that is used for support shuttering.

Builing industry be unable to do without the steel bar concrete engineering.Member in the steel bar concrete engineering has plenty of prefabricated, has plenty of cast-in-site.Cast-in-site need be made and touch plate, and steel form has been represented wooden form at present, has saved a large amount of timber.Support shuttering need be used a large amount of pillars.The most area of the pillar that formwork is used also uses timber to make, and not only needs higher manufacturing technology, also wastes a large amount of timber.

The purpose of this utility model is the problem that also needs higher operating technology at a large amount of timber of present use timber formwork pillar consumption, provides a kind of height-adjustable steel adjustable formwork pillar.

The utility model is achieved in that adjustable formwork pillar comprises upper supporting column, lower supporting rod, top bottom-disc, low bottom-disc and a threaded sleeve.There is a top bottom-disc upper end of upper supporting column.One round eye is longitudinally arranged on the upper supporting column.There is a low bottom-disc lower end of lower supporting rod.The top of lower supporting rod is for being shaped on externally threaded thread segment.Longitudinally have a vertical slit on the thread segment.Thread segment and threaded sleeve engagement.Handle is housed on the threaded sleeve.Also be provided with the shop bolt that passes vertical slit of lower supporting rod and upper supporting column eyelet on the adjustable formwork pillar.Upper and lower pillar is hollow section.Four limits on upper and lower chassis all are shaped on arc notch.

During use, upper supporting column inserts in the lower supporting rod, and shop bolt is positioned at threaded sleeve top, behind the vertical slit on the lower supporting rod, inserts in the eyelet of upper supporting column.Rotate threaded sleeve by handle, threaded sleeve just drives upper supporting column by shop bolt and rises or descend, and realizes a small amount of adjustment of pillar.But, change relative position with lower supporting rod to the adjustment direct pull upper supporting column of big distance.

The utility model is compared with wooden pillar, can save a large amount of timber, installs, and adjusts all more conveniently, saves a large amount of man-hours, need not the skilled craftsman simultaneously and operates favourable reduction construction costs.

Fig. 2 is the lower supporting rod front view;

Fig. 3 is the vertical view of Fig. 2;

Fig. 4 is the upper supporting column front view;

Fig. 5 is the vertical view of Fig. 4;
