Problems solved by technology
[0002] In order to pre-groove or hole in the formed concrete, the current construction method is relatively complicated: it is necessary to use at least eight formworks to arrange a zigzag pouring cavity, and then pour concrete mortar into the cavity. Remove formwork
Due to the many edges and corners of the concrete channel-shaped beam, the construction period is longer, especially in order to support the eight formworks, it takes a lot of labor and time, and the construction quality cannot be guaranteed.

Embodiment Construction
[0007] 1. Make a foam strip 1 with the same size as the slot or hole.
[0008] 2. Fix the foam strip 1 on one side of the template 2.
[0009] 3. The formwork 2 and other formworks 3, 4 and 5 are surrounded to form a concrete pouring cavity and relatively fixed.
[0010] 4. Pour concrete mortar 6 into the cavity.
[0011] 5. After maintenance, after the concrete mortar 6 is cured, remove all formworks 2, 3, 4, and 5, and remove the foam strip 1, leaving the groove or hole required for the design at the position where the original foam strip 1 was located.

The invention discloses a construction method for grooving and punching on concrete, relating to the technical field of construction engineering, in particular to an engineering technology for grooving and punching on concrete. The method comprises the following steps of: manufacturing a foam bar of which the size is same as that of a groove or a hole, fixing the foam bar on one side of a template, and enclosing the template and other templates into a concrete pouring cavity; and pouring concrete mortar into the cavity, detaching the template after the concrete mortar is cured, and removing the foam bar. Due to the adoption of the method, the erection of at least three templates is reduced, the shaping size accuracy of the foam bar is easy to control, and the foam bar is convenient to fix with the template, and is more convenient to remove after molding. According to the method, convenience is brought to manufacturing, the labor force and work period are saved, and the quality accuracy is high.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to the engineering technology of retaining grooves and retaining holes in concrete. Background technique [0002] In order to pre-groove or hole in the formed concrete, the current construction method is relatively complicated: it is necessary to use at least eight formworks to arrange a zigzag pouring cavity, and then pour concrete mortar into the cavity. Remove formwork. The many edges and corners of the concrete trough-shaped beam make the construction period longer, especially for supporting the eight formworks, it takes a lot of labor and time, and the construction quality cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to propose a construction method capable of ensuring the accurate size of concrete retaining grooves and retaining holes. [0004] In the present invention, foam strips of the same size as the...
