Referring to fig. 1-7, the utility model relates to a pour template convenient to go into mould, including comb type board 4 and mould chamber board. The appropriate cavity plate is typically selected for the desired preform beam shape and size, and for a preform T-beam the cavity plate typically includes associated transverse and longitudinal cavities. When the cavity plate is used for pouring the T-shaped beam, the upper end of the cavity plate is open, and a transverse cavity is defined by the comb-shaped plate 4 and the upper end of the cavity plate. The comb-shaped plate 4 is provided with a plurality of clamping grooves with openings at the upper ends, and the depth and the width of the clamping grooves are generally arranged according to the wing plate steel bars 11.

The clamping assembly may be a latch structure, or a jack or the like. When the clamping assembly is a jack, a plurality of clamping assemblies are generally arranged in the vertical direction and respectively act on the side plates 2 from different height positions to keep the two side plates 2 at relative positions. Preferably, the clamping assembly comprises a first pull rod 61, a second pull rod 62 and a support frame 3. The supporting frame 3 is located outside the side plate 2, and the first pull rod 61 and the second pull rod 62 respectively penetrate through the supporting frame 3 and are located at different height positions. Generally, both ends of the first pull rod 61 and the second pull rod 62 are provided with threads, or are provided with threaded rods, and are provided with nuts in a matching way to achieve a tensioning effect.
