Definitions
- This invention relates to spraying apparatus and, more especially, to apparatus which is suitable for spraying building materials such as concrete or plaster.
- Coating materials such as concrete or plaster used in the building trade are conventionally applied to surfaces using hand tools. These hand processes require a certain degree of skill and are not particularly efficient where large surface areas need to be covered, especially where time is limited.
- the floor/ceiling structure is a composite structure comprising steel rods and concrete with wood wool wadding inserts. It has been found, however, that with this sort of construction, there is a tendency for the concrete to recede from the steel rods into the wood wool wadding leaving the steel rods exposed. This can be dangerous because the rods are exposed to corrosion and are also liable to buckle in a fire.
- apparatus for applying a coating to a surface comprising a mobile carriage and a boom mounted on the carriage, the boom carrying a spray head adapted to be supplied, in use, with the material to be applied as the coating and adapted to spray the material on to the surface to be coated.
- a suitable building material such as concrete or plaster is sprayed on to the surface from an easy to handle and mobile apparatus. Large areas can be covered easily and quickly even in the case of ceilings.
- An early prototype of the apparatus has been used experimentally on a building suffering from the contruction defects mentioned above and resulted in the completion in two weeks of work which would have previously taken up to three months.
- the apparatus is capable of applying many forms of industrial, agricultural and domestic coatings to various surfaces.
- the boom may be hollow and the coating substance is supplied to the spray head through the inside of the boom, or may be supplied via a pipe attached to the boom, and is ejected from the spray head by a compressed gas, conveniently air, from a gas supply line running alongside the boom, or possibly also inside.
- the boom may be formed from a number of sections telescoped together so that its length may be adjusted. Such adjustment may simply be by hand or the apparatus may be constructed to be adjusted by other means, for example mechanically, electrically, hydraulically or pneumatically.
- the carriage may comprise a trolley on which is mounted a vertically extending support shaft which carries the boom, the boom being mounted on the shaft for pivotal motion in a vertical plane and the shaft being mounted on the trolley for rotation about a vertical axis.
- the rotational freedom of the support shaft may be achieved by providing the support shaft with a hollow lower section forming a sleeve which fits over a vertically extending column on the trolley.
- the advantage of this arrangement is that coating substance falling from the surface being coated does not foul the mounting.
- the trolley is wheeled or tracked and it may be provided with a motor e.g. on air, diesel, petrol or electric motor so that the operator does not have to push the trolley.
- the boom may also be provided with a counter-weight and/or the relative motion of the boom and support shaft may be damped so that it is easier to handle.
- the spray head may comprise a chamber to which the substance and gas under pressure is supplied and an aperture allowing communication between the chamber and the atmosphere and through which the substance is forced by the gas.
- the chamber may be defined by a bowl shaped flare on the end of the boom, the open end of the flare being closed by a cap containing the aperture and made from plastics or rubber.
- Different designs of cap or different types of spray head may be provided to provide different shapes of the spray dishcarge or to cope with different substances to be sprayed.
- the counter-weight may have a variable weight and/or position to allow it to be adjusted to different density spraying materials.
- FIG. 1 is a side view of apparatus embodying the invention
- Figure 2 shows alternative parts for the apparatus of figure 1;
- Figure 3 shows a part of the apparatus of figure 1?
- Figure 4 is a top view of the apparatus of figure 1;
- Figure 5 is a side view of part of the apparatus of figure 1?
- Figure 6 show further alternative parts of the apparatus of figure 1;
- Figure 7 is a cross-sectional view of a spray head used on the apparatus of figure 1.
- the spraying apparatus comprises a wheeled carriage 1 on which is pivotally mounted a boom 3.
- the carriage 1 comprises a trolley having a base part 5 to which the wheels 9 are attached and a vertically extending column 7 on which a hollow or part-hollow shaft 11 is mounted.
- At least the lower part 13 of the shaft 11 is hollow and fits over on the column 7 and is mounted on an internal pivot 19 which includes a downwardly extending pin 20 which engages a hole in the top of the column 7.
- the upper part 15 of the shaft may be hollow or solid.
- a locking screw 21 which may be tightened against the column 7 to lock the shaft in any particular position or simply to damp the motion of the shaft.
- the carriage 1 is provided with four wheels 9, although in an alternative embodiment, shown in figure 3, three wheels may be used.
- the wheels are adapted to the particular conditions in which the apparatus is to be used - e.g. they may have low pressure tyres fitted if the ground is rough.
- the trolley may alternatively be provided with tracks. In the illustrated embodiment the trolley is not powered but is simply wheeled into position and moved around by the operator. In an alternative embodiment, however, a motor is provided which may be powered, e.g. by the compressed gas used in the spraying equipment or by another type of motor, so that the apparatus can be moved under power.
- the boom 3 is mounted on the shaft 11 by means of a axle 25 retained in a slot 23 in the top of the mounting shaft.
- the fact that the boom is held on the shaft and in turn the shaft is held on the column 7 simply by their own weight means that the apparatus may be readily disassembled either for storage or transport and so that different length booms, as shown in figure 2, or different length shafts as shown in figure 6, may be fitted.
- the different length shafts and different length booms allow the apparatus to be used in a variety of locations.
- the boom 3 is constructed from several sections telescoped together so that its length may be varied.
- the shaft 11 may also be formed in this way. In both cases locking or damping means are provided so that the length of the boom or shaft do not vary during spraying.
- the boom 3 comprises a hollow part 4 terminated at one end by the spray head 32 and at the other end by an inlet 30 to which the substance to be sprayed is supplied.
- the inlet 30 is disposed on the opposite side to the spray head of the boom's pivotal mounting point but in alternative embodiments it may be on the same side.
- the inlet 30 is adapted so that a standard pressure hose for the substance being sprayed can be connected to it.
- a counter weight 38 On the opposite end of the boom to the spray head there is provided a counter weight 38 which may have a variable mass e.g. by the addition or subtracting of fluid, for example water or sand, and/or may have a variable position along the boom.
- the counter-weight is provided to balance, the weight in the hollow part 4 of the boom of the substance being sprayed.
- the boom is provided with two handles 40 and 42 positioned so that the operator can easily guide the spray head.
- a damper may be provided to damp the relative movement of the boom and the mounting shaft.
- a locking screw is provided (not shown) so that the boom may be locked in a particular angular position relative to the shaft.
- the substance is sprayed by a compressed gas, in this case, air, supplied to the spray head by an air line 34 running along side the boom and terminating in a connector 36 near to the inlet 30.
- the spray head comprises a flared, bowl-like chamber formed on the end of the hollow boom and to which compressed gas is supplied via pipe 34 and the substance to be sprayed via the hollow boom 4.
- the bowl is capped by a rubber or plastics cap 33 held on, if necessary, by a hose clip or clamping ring (not shown) and including an aperture 35 through which the substance is sprayed.
- substance supplied via the boom 4 fills the chamber 37 and is sprayed out from it by compressed gas supplied via line 34.
- Different caps having different apertures may be used for different spray patterns or different substances.
- the use of a removable cap 33 allows the spray head to be cleaned easily.
- the spray head is adapted to be removable for cleaning and/or to provide different spray patterns or spray different substances.
- This embodiment of the apparatus is particularly useful for spraying concrete, but it is envisaged that other embodiments may be used for spraying other building materials, e.g. plaster.
- This apparatus is easily usable with the conventional equipment for mixing and pumping concrete (which may, for example, use a screw pump which mixes as well as pumps the concrete or other material) .
- Such equipment conventionally includes an air compressor.
- the boom and trolley are constructed from aluminium although any other material can be used which is reasonably resistant from corrosion - particularly from corrosion by the substances which are being sprayed.
- the movement of the boom is also possible for the movement of the boom to be powered, for example with electrical, hydraulic or pneumatic assistance and, where a telescoping boom and/or shaft are used, for the telescoping action similarly to be power actuated.
