摘要:
The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod' s ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

The subject of the invention is a novel plasterboard and its manufacturing processes. The novel board comprises, on one side, two first parallel feathered edges and, on the other side, two other, second, parallel feathered edges that are perpendicular to the first ones; or, on one side, two first parallel feathered edges and, either on the same side or on the other side, two second parallel feathered edges that are perpendicular to the first ones, the said other parallel feathered edges having a width of between 100 and 200 mm; or, on one side, two first parallel feathered edges and, either on the same side or on the other side, two second parallel feathered edges that are perpendicular to the first ones, the said second parallel feathered edges having a width such that the ratio of the width of the said second parallel feathered edges to the width of the said first parallel feathered edges is between 1.5 and 5.

A basement wall is provided which includes a precast prestressed hollow core concrete panel. The panel has a plurality of horizontally extending voids and a plurality of horizontally extending tension cables. The panel has a lower portion extending below grade. The panel preferably has a layer of wire mesh positioned between the voids and the inner surface or between the voids and the outer surface. An end cap for the panel is also provided. The panel can have an impressed brick pattern on the above-grade outer surface and the panel can have a window opening, a brick ledge and/or a beam pocket.

The invention relates to a device for the separation of a plastic clay strand (2), movable longitudinally of a transport passage (3), into green bodies (2a), having at least one notching device (1) for notching of the clay strand (2) and a cutting device for cutting the clay strand (2) in the notches, wherein the notching device (1) has notching strips (4) arranged on all sides of the transport passage (3). In order to improve the device with regard to the notching device (1), all notching strips (4) are mounted independently of one another and they are movable at the same time out of a release position into a notching position offset towards the middle axis (3a) of the transport passage (3), and back again.

A method and apparatus for providing radiused corners on a crack control groove is provided. A radius on the two opposing corners of the crack control groove is simultaneously formed by inserting a pilot segment of a rotating cutting blade into the groove to chase the groove with the blade. The cutting blade has side cutting segments on opposing sides of the pilot segment. The side cutting segments have a concave shape with abrasive material thereon and are located and sized to cut a predetermined radius on the opposing corners 32. Convex shaped shoulder segments inhibit the formation of a well if the blade cuts too deeply. The pilot segment advantageously has no abrasive on its sides so it does not widen the groove, and the pilot segment is shorter than the depth of the groove so it does not deepen the groove.
