Definitions
- the invention relates to a piping nozzle comp ⁇ rising " housing having an exit opening for liquid-con ⁇ taining jointing material which is introduced under pressure into the housing interior through an inlet open- ing in the wall of the housing, with the aid of a pipe.
- Such piping nozzles intended for supplying jointing material by which is meant here and in the fol ⁇ lowing a pumpable mortar or like substance used to bind together building blocks or like elements in the construc- tion of masonry walls or facades, form part of plant appa ⁇ ratus with which jointing material is pumped from a cent ⁇ ral storage container to the masonry site through hoses or some other form of conduit.
- a prime object of the invention is to provide a piping nozzle which will fully restore, or at least substantially fully restore the mortar to its original consistency and viscosity, and mix the more readily flowing layer of mortar into the more sluggish mass of mortar.
- Figure 1 illustrates an exemplifying embodi ⁇ ment of a piping nozzle according to the invention used in the construction of a masonry wall;
- Figure 2 is a cross-sectional view taken on the line II-II in Figure 1 ;
- Figure 3. is a cross-sectional view taken on the line III-III in Figure 1 ; and Figure 4 illustrates the cross-section of a modified nozzle.
- Figure 1 illustrates part of a masonry wall constructed from building blocks, of which three are referenced 1 , 2 and 3.
- the building blocks are held together by bed joints, for example the bed joints 4, comprising mortar or some other liquid-containing jointing material, and heading joints, such as the illustrated heading joints 5 and 6.
- the upper building block 1 together with the remaining blocks incorporated in the same horizontal layer as thebuilding block 1 , is intended to receive a bedding layer of mortar for a subsequent layer of blocks, and the heading joints bet ⁇ ween adjacent blocks are to be filled.
- the bed joints comprise two mutually parallel strings or beads of mortar applied during movement of the nozzle in the direction of the arrow C, with the aid of two strings of mortar A and B.
- the piping nozzle of this embodiment comprises a housing 7 having a for- wardly located wall 8 ( Figure 2) as seen in the direc- tion of movement C, and a rearwardly located wall 9, which is parallel with the forwardly located wall 8.
- the two walls 8 and 9 are connected to two mutually parallel, rectangular side-walls 10 and 11, the vertical extension of which is somewhat greater than the vertical extension of the rectangular walls 8 and 9, so as to leave a lower mortar-exit opening 12 which presents a centrally located tongue-like scraper device 13, the lower edge part of which lies on the same level as lower, straight or optionally slightly arcuate edges 14, 15 of respective side-walls 10, 11, these edges 14, 15 forming "guides" for the housing 7 and sliding against the building blocks as the nozzle moves there- along.
- the inlet pipe is suitably displaceable verti ⁇ cally on the side-walls, in order to permit adjustment of the distance between the underside of the pipe and the underlying building blocks.
- the forwardly located wall 8 which similar to the rearwardly located wall 9 has a length correspond ⁇ ing substantially to the width D of the building blocks, has a lower edge located on the same level as the afore- said edges 14 and 15, although this is not absolutely essential and an opening of, for example, the same height as the opening 12 can be left.
- the side-wall 11 has provided therein an inlet pipe 17 to which there is connected a hose or like conduit 18, through which mortar is conducted from the storage container or silo mentioned in the introduction.
- a tubular inlet means 20 Connected to the inlet opening formed by the inlet pipe 17 ( Figures 2 and 3) is a tubular inlet means 20, which in the illustrated embodiment is assumed to have a circular cross-section, as has also the inlet pipe 17, and which extends bet ⁇ ween the two side-walls 10 and 11 and is terminated by the wall 10.
- the peripheral part of the inlet means 20 remote from the outlet opening 12 has formed therein an upwardly open slot 21.
- this slot has been formed by removing the pipe-wall in a plane such as to obtain a V-shaped opening, the greatest width of the opening being located at the side- wall 10 and its smallest width at the inlet opening 19.
- This embodiment is of particular importance when rela- tively large quantities of mortar are pumped into the housing, the intention being to compensate for the pressure drop occurring along the whole length of the inlet means 20, and thus to cause the same quantity of mortar to flow out along the whole length of the inlet means.
- the slot 21 may be given a uniform or at least substantially uniform width.
- a dividing means 22 Arranged centrally above and along the slot 21 is a dividing means 22, which in the illustrated embodiment also form the roof of the housing 7 remote from the inlet opening 12.
- the dividing means 22 of the illustrated embodiment comprises two substantially semi-cylindrical plates 23 and 24, the mutually facing edge parts of which are joined together to form a wedge-shaped edge 25, the apex of which lies along the geometric centre axis of the inlet opening 19 and the inlet pipe 17, and which projects slightly in ⁇ wardly of the defining line of the inlet opening 19.
- Two mutually parallel outer edges of the plates 23 and 24 are joined to the forward and rearward walls 8 and 9.
- the illustrated arrangement merely constitutes an exemplifying embodiment of the invention, and can thus be modified in various ways.
- the illustrated dividing means may be replaced with a metal plate bent to a triangular shape, as indicated by the broken line 26 in Figure 2 and the apex of the triangle may be caused to project into the mass of mortar pumped through the opening 19.
- the dividing means 22 preferably extends along the whole width of the nozzle, as assumed in the aforegoing, said means may be made much shorter, for example half the aforesaid width, while still effectively mixing the mass of jointing material.
- the mass of jointing material will not be subjected to the same preferred deflecting movement as that obtained with the semi-cylinders 23 and 24, although the defining or terminating walls 8 and 9 form requisite guide means.
- the outer walls 8 and 9 of the housing 7 may have the form of part-cylin- ders, wherewith the guiding and mixing effect obtained is equally as good as that obtained with the dividing means 22.
- the upper part may be provided with a single plate directed towards the gap 21, this plate being effective to divide the stream of jointing material flowing through the gap 21 in the manner desired.
- Figure 4 is a sectional view taken in accordance with Figure 2.
- the two walls 8 and 9 have cylind- rical upper parts whose edges are joined together along a line 28 which extends along the gap 21 and which is adjoined by an elongated, planar plate 27, which forms the dividing means.
