Adjustable support frame for template of constructed beam

The utility model relates to an adjustable support frame for a template of a constructed beam. The adjustable support frame comprises an adjustable cross frame, vertical frames, oblique supports and split bolts, wherein the adjustable cross frame is split into a cross-bar I and a cross-bar II which are clung to each other and can move relative to each other; the middle parts of the cross-bar I and the cross-bar II are vertically welded with the vertical frames respectively; the oblique supports are welded between the tails of the cross-bar I and the cross-bar II and the bottoms of the vertical frames; the split bolts are fixed between the vertical frames at the two sides; the cross-bar I and the cross-bar II are connected by connecting bolts; the split bolts can move vertically; the included angle between the vertical frames and the oblique supports is 30-45 DEG. Compared with the prior art, the adjustable support frame has the beneficial effects that 1) the space between the vertical frames can be adjusted according to the cross-section width of the beam, the scope of use is enlarged, reusability is realized, and the cost is reduced; 2) the structure is simple, installation and adjustment are convenient, and the construction progress is improved effectively; 3) the split bolts and triangles on both sides are arranged to fix the oblique supports, the structure is firm and stable, and the geometry size and appearance quality of a building are favorably guaranteed.
