Abstract

The invention relates to a prefabricated reinforced concrete hollow template internally provided with cross holes and a molding and forming device of the prefabricated reinforced concrete hollow template. The hollow template is internally provided with longitudinal through holes with round cross sections along the length direction and latitudinal through holes with square cross sections along the width direction, wherein the longitudinal through holes are arrayed parallel one another, the latitudinal through holes are also arrayed parallel one another, and the diameter of each longitudinal through hole is less than the length of the side of each latitudinal through hole. Two large surfaces of the hollow template are flat surfaces formed by molding. A casting mold of the molding and forming device is of a vertical type and provided with one or more mold cavities; each mold cavity is surrounded by a front face plate, a rear face plate, a left side plate and a right side plate; a core tube frame or upper side plate capable of fixing a vertical core tube is arranged on the upper part or above each mold cavity; and the left side plate, the right side plate and the upper side plate are provided with a plurality of horizontal holes and vertical holes respectively. Each surface of the hollow template processed by using the molding and forming device is flat without being polished and subjected to similar treatment. The hollow template is high in strength and good in quality, can be directly used for the construction of a load-bearing wall with few procedures in a short time and can ensure that the load-bearing wall is not easy to shrink and crack.

Description

technical field

[0001] The invention relates to a formwork for building and its forming equipment, in particular to a reinforced concrete hollow formwork for building with vertical and horizontal two-way intersecting holes and a vertical mold forming equipment for making the hollow formwork. Background technique

[0002] In the existing building construction, formwork is usually installed first, and then concrete is poured on-site between the formwork to form a wall, and the above-mentioned formwork is removed after the wall reaches a certain strength requirement. The construction method has many procedures, long construction period, huge workload of on-site assembling and dismantling formwork, and a considerable part of the dismantled formwork cannot be reused many times, resulting in waste of materials.

[0003] Existing prefabricated panel processing equipment usually uses horizontal molds, and the processed panel is in a horizontal position, and only one panel can be pro...
