The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

Buildings are constructed using the tilt-up technique from concrete elements that have contours that are at least partially curved. The concrete elements are made by casting in molds. The molds are assembled from mold pieces selected in a kit that contains a limited set of shapes. Molds assembled differently can produce concrete elements with a large variety of contour shapes.

What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

A method for adjusting a sidewall unit (1) of a casting mold for concrete products, which sidewall unit comprises a support structure (2, 32, 42) and a mold surface plate (3, 3′, 33, 43) fixed to the support structure, and which sidewall unit is fixed on a casting bed (8), wherein the mold surface plate comprises at least two portions (3, 3′) extending along the length of the sidewall unit and connected to the support structure (2) and the vertical position of at least one of the portions (3), defined by orientation of the sidewall unit (1) fixed on a casting bed (8), is adjusted to form a gap (9) extending along the length of the sidewall unit between the portions. The invention also relates to such a sidewall unit.

An atypical-molded-body manufacturing device according to the present invention comprises at least one shape output unit comprising a plurality of movable rods provided to be able to move up and down and arranged along a first direction. A driving module transfers a driving force to the movable rods, thereby moving each of the plurality of movable rods to a predetermined height. An atypical curvature is formed by a difference in level configured by the upper end of each of the plurality of movable rods that have moved to the predetermined height.

A manhole base assembly and a method for making the same employ a non-cylindrical, low-volume concrete base that is fully lined to protect the concrete against chemical and physical attack while in service. This lined concrete manhole base assembly may be readily produced using a modular manhole form assembly which can be configured for a wide variety of geometrical configurations compatible with, e.g., varying pipe angles, elevations and sizes. The form assembly is configurable to provide any desired angle and elevation for the pipe apertures to interface with various underground systems, and can be formed on-site to facilitate compatibility with existing structures. The assembly provides for flexible, modular construction of a wide variety of lined manhole base assemblies at minimal cost, reduced concrete consumption and reduced operational complexity. The modular nature of the production form assembly also facilitates reduced inventory requirements when various manhole base assembly geometries are needed.

An aspect concerns a method (10) of producing a precast building product. The method (10) includes providing a mould (26) to receive a pourable building substance to be cured. The method further includes the steps of pouring the building substance into the mould and allowing the poured building substance to cure inside the mould to form a sold mass body. The method further includes providing a wire-cutting assembly operatively associated with the mould and cutting the solid mass body inside the mould into separate building products.
