LOCK-JOINT FOR WALL-SLABS, BRICKS, TILES, OR THE LIKE.
Specification, of Letters Patent.
Application filed August 14. 1906.. Serial No. 330.616-
Pmatea Jan. 21, 1908. I
To all whom it may concern:
Be it known that I, R BERT MALANQON, a
citizen of the French Republic, residing at London, England, have invented certain new and useful Improvements in Lock-Joints for Wall-Slabs and the Like, of which the fol lowing is a specification.
This invention has reference to sectional fire-resisting or other partition slabs, bricks and the like elements and it'consists in a new form of lock joint obtained by connecting adjoining sections or elements together by means of a hardsetting grouting which passes from screwed holes in one sectlon .or element to suitably facing holes, also screw threaded, in the juxtaposed section or element. At one side or end of the section these screwed holes are connected together by a transverse hole through which the grouting is supplied. The grouting is then poured in and passes from the transverse hole to the branch holes and their facing holes which form continuations thereof. In a modificationthe facing hole remote from the transverse hole or assage may be closed by a key or plug W ich has a narrower projection, serrated or screw threaded and passing into the hole which leads to the transverse passage. The space between this narrower projection and its surrounding wall may then be filled in with grouting and the juxtaposed slabs thus secured together.
The invention is illustrated upon the accompanying drawings in Which,
Figure 1 1s a perspectiveview of one of the slabs, sections or elements. Fig. 2 is a similar view but more nearly an end elevation.- Fig. 3 is a perspective view of part of a wall formed of these sections. tion on a larger scale of a plug or bolt intended to be inserted into facing holes in a modification of the invention. Fig. 5 is a view of juxtaposed slabs in section upon the fillet or tongue, when fitted with the plug according to Fig. 4.
Q The slab, section or element is composed of any suitable fire-proof, fire -resisting, sound-deadening or other material as desired. The body a is provided on two of its adjoining or meeting sides with a tongue or fillet 1) preferably of inverted V shape. On the remaining two adjacent or meetlng sides of the body a a groove 0 is formed of corresponding shape so that the tongue I) of the next block or element will fit therein. At one of the sidesof the slab the latter is Fig. 4 is an elevafurnished with two or more parallel holes 41 d which are screwed with a thread which may be of coarse itch. The opposite side of the slab is rovi ed with holes d equal in number to an corresponding in position with the holes d. The holes d. are similarly screwthreaded but while the holes d d are connected together by a screw-threaded hole or passageie extending from top to bottom of the slab and into which the holes (1 d deliver, the holes (1 need not be provided with a passage e.
The tongue or fillet b is shown provided with-a small half-round groove f and the groove 0 is also shown with a similar halfround groove g. A strip of binding wire it of white metal or other suitable material, as is well known for this purpose, may be employed' if desired. When the slabs have been placed in position, and strengthened or bound if necessary by the aforesald binding wire, a liquid grouting of plaster, cement or other suitable material is poured down the passage 6 and extends therefrom to the branch holes dd d d on each side of the joint. When the grouting sets hard the slabs are firmly locked together since the coarse threads around the holes in effect bite into tongues 12 and grooves 0 maybe of any desired shape and section.
The slabs a are all of similar construction so that the tongues b of any one slab will engage the grooves c of juxtaposed slabs in such a way as to leave afiush joint and the holes (1 (1 face the holes d d. The arrangement is clearly illustrated in Fig. 3.
In a modification, see Fi s. 4 and 5, I may arrange to insert a screwed plug oi bolt 6 i into one of the holes (1 the projecting end i of the bolt being of narrower section than the plug portion i but it is also screwed with a coarse pitch thread or serrated. The projectin part is then passed into the facing hole (i when the blocks are juxtaposed, see Fi 5, and the space between such narrowed b0 t i and the hole be filled with grouting as in the previous example. In lieu of the holes (1 and d and passage e being screwthreaded they may be otherwise finished in flush with juxtaposed elements, said element having holes in corresponding positions at each of two opposite ends thereof, and a passage extending downwards 1nto said element near one end through which grouting may be fed to said holes, to unite said element with the adjacent elements of the same course, said passage stopping short of the base of said element, to prevent contact of lying course.
2. In a slab, brick or tile for the purposes described, having a plurality of holes at one end of the slab body and correspondingly l alined holes at the opposite end thereof,said v holes extending inwardly of the slab in the plane thereof, a transverse passage extending from the top towards the bottom of the slab and meeting the inner ends of the holes at one end of the slab, in combination with a bolt designed to couple the ends of adjaeent blocks, said bolt being fitted into one end of one block and having a reduced portion adapted to extend into the orifice at the opposite end of the adjacent block, said reduced portion leaving a space for the access of groutlng from the transverse passage.
In testimony whereof I afiiX my slgnature in presence of two witnesses. V sald groutlng w th elements of the under- ROBERT, MALANQON.
