摘要:
A modular block, comprises a front surface, a rear surface and two sides each side extending between an edge of the front surface and an edge of the rear surface of the block, a channel extending through the block between the two sides and open at a bottom surface of the block, and a through-bore extending between a top surface of the block and into the channel to receive an arm of a lifting or support member.
摘要:
A lever arm (5) is pivotable relative to a support mounting (2) to engage and displace a contact which causes clamping limbs (12a,12b) pivotally mounted to the support mounting (2) to be pivotally displaced between a release configuration (in which an object is not clamped for lifting) and a release configuration (in which the object is clamped for lifting). The lever arm (5) by which the apparatus and object are lifted provides high mechanical advantage for the clamping force.

There is disclosed a calliper-type lifting device wherein the work engaging parts at the ends of the pivotted levers are adapted for location in a narrow space suiting the aid for the manoeuvering of kerbstones, paving flags, building blocks or the like.
摘要:
The invention concerns a block and a method for building walls wherein the blocks are assembled through thin joints, the block being easily adjusted, with blocks adapted to provide high manufacturing dimensional tolerance. The binder required to assemble the blocks is carried out by levelling the binder deposited in a groove of the building block. The building block is gripped, handled, deposited and adjusted when the wall is being constructed with a handle hammer specific to the block. The height of the blocks eliminates the need to produce cuts to adapt to the modulation of a building. The corners and masonry structural walls are built by bonding together the walls without nesting.

L'invention concerne un élément de construction 101,101',201,301 ayant une longueur l, une largeur d et une hauteur h avec des axes sensiblement perpendiculaires, où ladite longueur l est préférablement au moins égale à la largeur d. L'élément de construction comporte une première et une deuxième faces 111,112, sensiblement orientées dans des plans parallèles aux axes de la longueur l et la largeur d et écartées dans l'axe de la hauteur h, et une troisième et une quatrième faces 113,114, sensiblement orientées dans des plans parallèles aux axes de la largeur d et la hauteur h, et écartées dans l'axe de la longueur l. Ladite première face 111 comporte deux nervures 121,122 longitudinales et écartées dans l'axe de la largeur d par un premier creux 123. Chaque nervure 121,122 a une hauteur h ni de 5 à 17 mm, préférablement 7 à 8 mm, relativement au fond dudit premier creux 123. Ledit premier creux 123 est ouvert au moins sur ladite troisième face 113. L'invention concerne aussi un procédé de production par moulage dudit élément de construction 101,101',201,301, un procédé pour construire un mur avec une pluralité de tels éléments de construction 101,101',201,301, ainsi qu'un mur construit suivant ledit procédé de construction.
摘要:
Device to carry construction material, which consists of two parts rotatably connected by means of a mobile axis (18), a first part (A) consisting of a basically square angle plate (6) one face of which is fixed to an end of a bar (4) and a second part (B) consisting of a second basically square angle plate (16) one face of which is fixed to a control handle (12) through means (14,15) adapted to be rotatably connected to said bar (4); said rotation being allowed on a plane which is common to said handle (12) and said bar (4), and said plates (6,16) presenting their concave parts facing each other when the two walls of the device are joined by means of said axis (18).

Die Einrichtung dient zum Heben von Hohlblockmauersteinen. Paarweise sind in einer Ebene liegende, L-förmige Greifer (1, 2) vorgesehen, deren eine Schenkel (3) nach unten gerichtet sind und deren waagrechte Schenkel (4) einander zugewandt sind. An den Enden der einander zugewandten Schenkel (4) sind selbsthemmende Gewinde (5) vorgesehen, wobei das Gewinde des einen Schenkels ein rechtsgängiges und das Gewinde des anderen Schenkels ein linksgängiges Gewinde ist. Diese Gewinde (5) sind von fluchtend zueinander liegenden Gewindebohrungen (6) einer Muffe (7) aufgenommen. Diese Muffe (7) weist einen rechtwinkelig zur Achse der fluchtenden Gewindebohrungen (6) seitlich abstehenden Handgriff (8) auf. (Fig. 1)
