An adjustable mold capable of making castings of various configuration is provided. The adjustable mold has an adjustable die with a core and an adapter, a protrusion, a cavity, and an outer portion with at least two sidewalls, at least two endwalls, and a base therebetween, which outer portion at least partially surrounds the adjustable die to thereby define a mold. During casting, molding material is poured in the mold and allowed to cure to make a casting. The adapter is replaceable to enable castings of multiple configurations to be cast suing the adjustable mold.

Wall block (2) made of artificial stone material; it has an overall elongate form and a first seating surface (10); an opposing second seating face (12); a first end face (14); an opposing second end face (16); a first wall surface side (18); an opposing second wall surface side (20); it has, on its first seating face, a first seating surface (4) and, on its second seating face, a second seating surface (6); it has a lateral surface (8) and a plurality of extension arrangements (30) arranged in a row on its first seating face (10) and a plurality of receiving arrangements (40) arranged in a row on its second seating face (12), these arrangements each being complementary to one another such that a particular extension arrangement fits in form-fitting engagement with a particular receiving arrangement of a third further wall block which is designed as a receiving arrangement of the claimed wall block, and such that a particular receiving arrangement fits in form-fitting engagement with a particular extension arrangement of a fourth further wall block which is designed as an extension arrangement of the claimed wall block, the particular extension arrangement and the particular receiving arrangement being designed such that the form-fitting engagement—considered per se—is possible both when the longitudinal central axes of the claimed wall block and of the third further or fourth further wall block are parallel to one another and when the longitudinal central axes of the claimed wall block and of the third further or fourth further wall block—seen in plan view of the first seating face or the second seating face of the claimed wall block—extend at an angle (81) to one another; and it is formed having a fin (60) at the transition between its first end face and its first wall surface side, and/or at the transition between its first end face and its second wall surface side, which fin protrudes beyond a virtual flat surface (61) located at the center of the first end face at a right angle to the longitudinal axis of the wall block.

A bulkhead system for a concrete casting bed includes a pair of base track members spaced apart from one another along a longitudinal direction and a pair of form walls each removably attached to one of the base track members. Each of the form walls has a lower end abutting one of the base track members and an upper end opposite the lower end in a vertical direction perpendicular to the longitudinal direction. Each of the form walls has a tendon slot extending into the form wall in the vertical direction from at least one of the upper end and the lower end. The tendon slot receives a tendon extending in the longitudinal direction.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

Flexible molds have an elastic membrane supported by modules, arranged next to one another along a horizontal longitudinal axis of the mold. Each module has traction units, each forming a respective group with a respective thrust unit, with the groups arranged opposite one another at a preset distance. Pairs of traction units are arranged opposite one another in a direction perpendicular to the axis, and the respective thrust units thereof are arranged therebetween. The modules hold the membrane with the mold via reinforced eyelets distributed on both edges parallel to the axis. Each traction unit has linear actuators arranged horizontally and another linear actuator arranged vertically, which together enable movement. The membrane is previously deformed according to an approximation of the prior design of a part to be molded, and prestressed according to a mathematical prediction of the deformation thereof after receiving a conglomerate in liquid or plastic state.

A catch basin trap for attachment to an opening in a side wall of a catch basin. The catch basin trap has a body with a front side for facing outside the catch basin, and a back for side facing inside the catch basin. The body defines a chamber, an inlet opening in the back side, and an outlet opening in the front side. A collapsible outlet pipe connector is attached to the outlet opening, configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end for coupling to an outlet pipe positioned outside the catch basin. The collapsed configuration stows the collapsible outlet pipe connector within the body, and the extended configuration permits watertight coupling of the discharge end to the outlet pipe. A method of installing a catch basin trap, and a method of making a concrete catch basin are also disclosed.

A formwork core for a formwork system for concreting a bell body including a base frame and two corner supports detachably fastened at a variable distance. The corner supports each bear two corner connection panels, which are arranged at a right angle to each other around the corner and can be synchronously retracted and extended without touching each other. The corner supports also bear corner angle pieces, which likewise can be retracted and extended and, in the completely extended state, close the gap between the two associated corner connection panels in order to form a vertical outer shell of the formwork core. The vertical edges of the corner connection panels, which vertical edges are distant from the corner, have screw flanges facing inward. Optionally, at least one side formwork panel can be inserted between the corner connection panels one side.
