The utility model discloses a chiseling-free mould product for concrete forming in the technical field of concrete pouring, which comprises a bottom plate, a plurality of rows of large rough forming structures are arranged on the upper surface of the bottom plate, small rough forming structures are arranged among the large rough forming structures in each row, each large rough forming structure is an inverted triangular tooth, and a plurality of small rough forming structures are arranged on the lower surface of the bottom plate. The small rough forming structure comprises two rows of small vertical teeth, the small vertical teeth are lower than the inverted triangular teeth, one row of small vertical teeth abut against the bottom edge of the inclined face of one adjacent inverted triangular tooth in the same row, the other row of small vertical teeth are close to the vertical face of the other adjacent inverted triangular tooth in the same row, and a gap is reserved between the small vertical teeth and the vertical face. Through cooperation of a large rough forming structure and a small rough forming structure, the contact area of new and old concrete is effectively enlarged, the formed new and old concrete is internally fused more firmly, the quality is stable and reliable, the anti-leakage effect can be achieved through cooperation with a formwork, the safety of the whole main body structure can be improved, and zero damage to the structure is achieved; and the service life of the structure is prolonged.

To provide a concrete formwork which can easily eliminate positional deviation even if the positional deviation occurs in the concrete formwork when an iron pin is fixed. [Solution] The concrete formwork comprises a formwork body (10) and a plurality of box-shaped iron pin-through sections (20) fixed to the formwork face (12a) and the face (12b) opposite the formwork face (12a) of the formwork body (10), and iron pins (50) are passed through the iron pin-through sections (20) to fix the formwork body (10) to an installation face (G) by the iron pins (50), forming a concrete formwork (1), and comprises a fine adjustment mechanism (100) that can finely adjust the relative position of the iron pin-through sections (20) based on the position of the iron pins (50) when the iron pins (50) are fixed.

The utility model discloses an angle-adjustable arc-shaped telescopic template, which relates to the technical field of construction templates, and comprises an arc-shaped panel and a support seat, an I-shaped frame is arranged between the arc-shaped panel and the support seat, a turn buckle is arranged between the I-shaped frame and the arc-shaped panel, a protective piece is arranged on the periphery of the turn buckle, and the protective piece is connected with the arc-shaped panel. The protection part comprises a first cover plate and a second cover plate which are mutually closed, extending cylinders are arranged at the upper end and the lower end of the first cover plate and the upper end and the lower end of the second cover plate correspondingly, the extending cylinders, the first cover plate and the second cover plate surround the turn buckles, and the upper end of the supporting base is fixed to the lower end of the I-shaped frame. The periphery of the turn buckle is wrapped by the first cover plate and the second cover plate, the first cover plate and the second cover plate can prevent dust and sundries from entering the turn buckle, the situation that normal operation is affected due to the fact that the turn buckle is difficult to rotate and abraded is avoided, meanwhile, a certain safety protection effect can be achieved, and personnel are prevented from being accidentally touched and injured.
