摘要:
A concrete block having comparatively light weight and capable of being manufactured easily and used in various fields of application; a block joint for the concrete blocks, capable of carrying out the arrangement of the concrete blocks simply and retaining the arranged concrete blocks in good order; and a structure made by using the concrete blocks and the block joints. The joint (1,2) has seats (1b,2b) which are formed by cutting off predetermined portions thereof and adapted to restrict positions in which the concrete blocks (3) are arranged horizontally and vertically so that horizontally adjacent and vertically adjacent concrete blocks have clearances therebetween, and which support corner portions of the concrete blocks (3) thereon, each of the concrete blocks (10) being formed in a cubic or parallelepipedal outer shape so that it has an outwardly opened hollow structure, by using a split core (12) which can be broken down and removed after the concrete has been hardened, thus obtaining a structure of which the interior of the concrete blocks (10) communicate with each other when a plurality of blocks (10) are horizontally and vertically arranged.

Es wird eine Befestigung von Verkehrsflächen im Freien mit Pflastersteinen (4) oder Platten aus Kunst- und/oder Natursteinmaterial angegeben, wobei die Steine in einem Bett aus Sand und/oder Splitt verlegt sind. Dabei ist vorgesehen, daß die Steine zusätzlich durch ein auf das Bett aufgelegtes, mit Durchbrechungen (5) versehenes, flächenhaftes Tragelement (1) abgestützt sind.
摘要:
Ein Abstandshalter 1 zum Festlegen der Fugenbreite zwischen Steinen, Platten 19, 20, 21, 22 oder dergl. besteht aus mehreren hohlzylinderförmigen, in etwa parallel zueinander verlaufenden Elementen 2, 3, 12 und jeweils benachbart liegende Elemente 2, 3, 12 sind dabei durch Stege 4, 5 miteinander verbunden. Damit sie eine schnelle Verlegung der Steine, Platten 19, 20, 21, 22 oder dergl. ermöglichen sowie eine saubere Anlage für die auf Fuge zu verlegenden Steine, Platten 19, 20, 21, 22 oder dergl. bilden und darüber hinaus eine erhöhte Gestaltfestigkeit erreichen, bilden jeweils zwei zueinander parallele Stege 4 und 5 die Verbindung zwischen den hohlzylinderförmigen Elementen 2, 3, 12.
摘要:
Metalled road with a road direction and constructed from road covering slabs (2,3) following one another in the road direction and plastic profiles (4) lying between consecutive road covering slabs, wherein the two consecutive road covering slabs are provided on their opposite-lying ends with a respective groove (7), and wherein the plastic profile extends into the respective grooves to form a tongue-and-groove-shaped joint, said joint linking two consecutive road covering slabs to form the metalled road.
摘要:
Apparatus for forming a liquid-tight seal across a gap formed between adjacent, interconnected first and second mats in a load-supporting surface includes first and second liquid impermeable, elongated seal members extending into the gap from the first and second mats, respectively. The seal members abut one another in the gap to form a liquid tight seal therebetween.
