In shuttering assemblies for moulding concrete buildings and structures in situ, it is known to provide sectionalised structures comprising a number of units each of general plate form, assembled edgewise to provide a common surface, and comprising separate tubular waling pieces characterised by stiffness against lateral bending included in the joints between the edges of adjacent panel rows, and crossing the joints of the assembly that are transverse to the rows. The present invention is concerned with this subject matter, and its object is to provide a waling memher having specialised uses difficult or impossible to known waling members while remaining capable of carrying out most if not all of the functions of those members.

The most useful species of known tubular waling members are those comprising a tubular body and a flange extending away from the rear face of the assembly. The adjacent panel edges are grooved so as to provide between them when they are assembled edge to edge a cavity whose crosssectional shape is that of the tubular body. Accordingly, as each row is erected and after the waling members are laid in position in the grooves preparatory to the erection of the next succeed-- ing row of panels, the tubular body projects above the edges of the panels and constitutes the highest level of the assembly. Conversely, if an opening is left in the assembly, the tubular body of the waling member, above the opening, projects downwardly into the opening. At times it is necessary or desirable to have elements extending from the continuous face of the assembly, through the assembly to the opposite face. If the cross-sectional shape of such elements corre sponds to or comprises a part corresponding to that of the waling member and the part is thin (for instance if the element is a sheet metal cross tie of appropriate shape), the projection of the tubular body above or below the joints between the panels is not disadvantageous, because the element can be laid over or under the waling member and included in the joint. But if the element is too thick for inclusion in the joint or does not conform to the cross section of the wal-- ing member, the projection of the tubular body above or below the panels is troublesome.

As an example, the element may be the frame of a door or window to be incorporated in a wall which is to be cast between parallel assemblies. Hitherto, it has been necessary to enclose the frame within the moulding cavity, so that, on demoulding, the architraves are flush with the cast walL The plaster coating subsequently applied to the wall will leave theframes recessed, which is normally not desirable.

The main object of the present invention is to provide a waling member which has all the advantages of the waling members considered above, but which may also be modified at need to permit elements to be passed through the assembly,

According to the invention, a waling member is constructed in two parts detachably secured together and collectively forming a tubular body of the cross-section of which each part provides substantially one half.

Further according to the invention, each part comprises a flange extending beyond the tubular body, the flanges of the two parts being overlapped and detachably secured together.

In one form of the invention, the flanges ex tend beyond the panels in the direction away from the continuous face, and are bolted together there.

The partsmay each also provide oppositely extending flanges which overlap and are included in the joint between adjacent panels; and may further provide elements for anchoring the wal-' ing member to the panels between which it lies.

The particular advantage of the waling member of the invention is that, when the parts are assembled, the member is capable of carrying out all the functions of the known tubular waling members mentioned above. When it is'required to pass an element through the assembly, thetwo parts of the waling member are separated and only one part is used. When engaged with the edges of the panels, the part in use is still a waling member in that it fulfills the function of aligning the panels, but it does so without presenting any significant projection above or below the panel edges as the case may be. Elements such as door and window frames may then be assembled to project beyond the moulding cavity into or even through the panel assemblies. When thus assembled, the frames come into close contact with the panel edges or a flange of the waling member over-lying said edges, so that the assembly is suitable to form the moulding wall.

Referring firstly to Figures III, IV and V, the waling members 2, which are known tubular waling members such as those mentioned above provide a tubular body 3, two flanges 4, and additional flanges v6, 6 forming hooks which engage shoulders I, I on the panels 8, 8.

The units 3, 4, 5, 6 of the members 2 are not separable.

If it is required to pass an element through or partly through th shuttering assembly, it is only possible to do so if the cross-sectional shape of the element corresponds, orcomprises a portion corresponding, to that of the waling member 2; and further, if the element or the said portion of it is thin enough to be included in the joint. For example, a cross tie such as that designated 33 in Figure VII, of sheet metal, can be included in the joint and extend through the joint without interference with the shuttering. But if the element is thick or does not conform with the crosssectional shape of the waling member, the tubular body 3 of the member, since it fills the space defined between the grooves I 0 of the panel edges, prevents it from passing through or-being included in the joint.

For example, such an element may b the frame of a door or window which is to be incorporated in a wall cast between parallel shuttering assemblies.

If an opening such as II (Figure V) were to be left in the shuttering assembly I2 for the frame, part I3 of the tubular body 3 ofgeach waling member 2 would project into the opening. Satisfactory edge engagement between the door fram and the panel edges at the opening I I would be impossible because of the projecting portion I3 of the waling member. Accordingly it is necessary to build the parallel shuttering assemblies without openings and to locate the door frames such as I4, and also window frames, within the moulding cavity I5, as in Figure IV. The frame I4 thus acts as part of the shuttering assembly and is cast into the walls I6 during the moulding operation.

The outer surfaces of the architraves I! of the frame I4 are flush with the faces of the cast walls 16 and, when the latter are plastered, the architraves of the door and window frames are left recessed as is shown in Figure VI. Thisis not desirable because it detracts from the appearance of the completed building and also because the edges IISa of the plaster coat IEb are vulnerable to knocks and liable to be broken.

The waling member of the invention is shown in Figures I and II. It includes the two parts I8, I9 each provided with a depression 20 which is triangular in cross-section and two oppositely directed flanges 2|, 22; and two Z-shaped elements 23, the limbs 24 of which overlap the flanges 2| and the limbs 25 of which are inwardly directed to act as hooks. The parts I8, I5 and the elements 23 are assembled with the flanges 2I and the flanges 22 overlapping and are detachably secured together by a series of bolts 26, which also secure the limbs 25 of the elements 23 to the flanges 2 I.

The waling member thus assembled is the equivalent of the known waling member 2 (Figure III) in that the parts I8 and I9 collectively provide substantially one half each of the crosssection of a tubular body 3a, and in that the flanges 2|, 22 correspond to the flanges 4, 5 of the known waling member 2; while the elements 23 correspond to the flanges 6, 6. Like the flange 4 of the waling member 2, the flange 22 is just wide enough to reach th moulding face 21 of th panels 8 with which the waling member is engaged; whereas the flange 2|, like the flange 5. projects beyond the rear face 28 of the panels. Its projection is, however, more pronounced to allow space for the bolts 26.

The waling member of the invention is able to carry out all the functions of a known waling member such as member 2 in that it align: the panels 8 by being included within the joint between the adjoining edges, and in that it engages the shoulders I of the panels 8 to resist outward bulging of the panels during the moulding operation. Like the known waling members, it is engaged with th panels by relative rotation, as is more fully described in the specification of applicants Patent No. 2,447,670, August 2 1948.

However, the detacha'bility of the two parts I8, I9 permits either part to be separately used, and to function as a waling member to align adjacent panels; while not presenting any obstructive projection above the edges of the panels it aligns, or below them as the case may be. This is illustrated in Figures VII to X. In Figure VII the panels 8 are assembled to provide an opening 28a, in face view, for a door frame Ida. The panels are assembled edgewise, and included in the horizontal joint 29 there is a member 30 which is one of the parts I8 or I9 of the waling member of the invention. The tongue formation 3| of the member 30 engages in the grooves 32 in the lower edges of the panels above the member and there is a cross tie 33 to hold the two shuttering assemblies (of which only one is shown) together.

Within the opening the door frame I 4a is positioned. The upwardly directed face 34 of the architrave I'Ia is jointed with the under face of the flange 22a of the member 38, and the outwardly directed faces 35 of the architrave with the vertical edge faces 35 of the panels 8 at the sides of the opening.

As in the known method, the door frame I411 constitutes part of the shuttering, but in so far as it defines the moulding cavity, the portion I5a of the cavity behind the architrave is wider than the cavity between the panels 8. This is made possible by the butting engagement of the faces 34 and 22a, which permits the architrave Ila to extend beyond the plane of the moulding face 31 of the shuttering and into the opening 28a without impairing the efficiency of the shuttering assembly.

The face 38 of the cast wall l6a is thus recessed relatively to the face 34a of the architrave ila, and, when the wall is plastered, the outer face of the plaster coat may be made flush with the face 34a, or even recessed.

In Figure IX the shuttering assembly is erected to leave an opening 28b, which receives a window frame Mb. Inthis case the member 30a is again one part l3 or H) of the waling member of the invention, but it is arranged with its tongue 31a downward so as not to project into the opening 281). At the upper vertical edge of the frame- Mb, the aligning member (not shown) is again one half of the normal waling member, with'its tongue upwards, as in Figure VII.

In order to centre the frame Mb within the opening angle, brackets 302) may be provided, the brackets being secured to the member 30a by the bolts 26a, and the limbs 300 of the brackets lying against the architraves of the frame Mb.

In Figure X, the sill I40 of the frame extends well beyond the panel assembly and the member 30a. In order to locate the frame 'relatively to the shuttering, an L-shaped bracket 30d is arranged with its limb 30c butting against the end face of the sill.

The use of the waling members of the invention avoids multiplication of the standard units employed to construct the shuttering assembly in that, at openings in the shuttering, the waling members at the horizontal edges of the openings are readily modified, to allow door and window frames to be built into the assembly, merely by detaching one of the two parts I 8 or 19 of the members and using the other alone. that the complete waling member providing the tubular body 3a is present over substantially the entire horizontal extent of the panels themselves, one of the two parts of the member may be made in sections, so that only sufficient of such part need be detached to extend across the door or window frame. This construction is illustrated in Figure XI in which the part I8 is shown in sections. Since the member is reversible end for end, only one of the two parts and one of the two Z-shaped elements 23 need be sectioned.
