- a device according to the invention is useful for flooring, wherein a flooring material, such as a cementitious flooring material, anhydrite flooring material or similar, is supplied to a floor structure.
- a flooring material such as a cementitious flooring material, anhydrite flooring material or similar
- One common type of flooring materials of this type is screed, underlayment, overlayment and other floor levelling materials.
- Such devices can also be used for supplying façade materials, such as rendering materials, and other types of materials, such as plaster, resin, etc. to a wall structure or other types of structures.
- the invention also relates to a system for supplying a hardening and pumpable or blowable building material to a material application site.
- the invention also relates to the use of such a device and the use of such a system.
- Flooring material such as screed
- the flooring material is supplied from the truck to an application site through a hose by pumping.
- the pump is, for example, arranged on the truck.
- the hose is connected to a material supply of said truck and extends to the application site, such as into a building structure.
- the hose is handled manually by an operator to distribute the flooring material, wherein the operator carries the hose and positions a free end of the hose at the desired application site.
- the hose is handled manually by a first operator and a second operator, wherein the first operator handles an outlet end of the hose for application of the flooring material at the desired position, and wherein the second operator lifts and moves the hose in suitable positions between the outlet and the truck to facilitate for the first operator to position the outlet end of the hose at the desired position.
- An object of the invention is to avoid the above mentioned problem of the prior art and provide a device and a system for supplying a hardening and pumpable or blowable or sprayable building material to a material application site which result in improved working conditions and reduces the risk of musculoskeletal disorders for at least one of the operators.
- Building materials of this type are generally heavy and often requires a heavy duty hose to be conducted a substantial distance by pumping or blowing. Hence, the combination of hose and material is heavy and cumbersome for manual handling according to the prior art.
- the present invention relates to a device for supplying a hardening and pumpable or blowable or sprayable building material to a material application site, comprising a hose for conducting said material from a material supply to an operator manually distributing said material on the application site by means of the device, the device comprises a load distribution support and a connector, wherein the load distribution support is connectable to the operator and comprises one or more connecting devices, and wherein the connector is connected to the hose and is connectable to the one or more connecting devices of the load distribution support to form an articulated connection between the support and the hose, so that the hose is supported on the operator through the articulated connection when the device is operated by the operator to distribute said material on the application site.
- the device according to the invention results in a favourable load distribution during operations, such as flooring operations with flooring materials in the form of screed, cementitious flooring materials, anhydrite flooring materials and similar, and improved working conditions for the operators.
- the load distribution support can comprise a waist belt and optionally one or two shoulder straps to form a harness. Such a load distribution support can quickly and easily be connected to the operator and distributes the load efficiently to the hip and shoulders of the operator.
- the device comprises a flexible tube connected to the hose.
- the hose can be a heavy duty hose adapted for transportation of cementitious materials, wherein the hose is quite rigid and heavy and is not easily bent or handled manually by the operator.
- the flexible tube can more easily be bent and carried over the shoulder of the operator than the hose. Further, the flexible tube can facilitate distribution of the material as it more easily than the hose can be bent in the desired direction.
- the flexible tube can be lighter and more flexible than the hose. Hence, the flexible tube results in a device which is easier and lighter to handle for the operator, which further reduces the risks of musculoskeletal disorders for the operator.
- the flexible tube can be connected to a rigid tube to be gripped and handled by the operator, wherein the flexible tube is arranged between the hose and the rigid tube.
- the rigid tube can be lighter than the hose. Hence, the rigid tube forms a manoeuverable part of the device, which can be directed in different directions due to the flexible tube.
- the rigid tube can be connected to a foldable tubing, such as a soft rubber tubing, to be manually folded by the operator to more easily prevent material from dripping from the device, e.g. when a pump for pumping the material or a compressor for blowing the material has been turned off and the device is to be moved to another position or location.
- the foldable tubing can be more flexible than the hose and the flexible tube, wherein the foldable tubing is easier to fold manually than the hose and the flexible tube. Hence, undesired drops of the hardening material on a floor structure can more easily be avoided.
- the connecting device can be arranged on a back part of the load distribution support, such as on the back part of the waist belt or on the back part of a harness.
- the connecting device can be arranged in a lower central part of such a harness.
- the hose can be connected to the back of the load distribution support, wherein the flexible tube can be arranged over the shoulder of the operator while the rigid tube is handled in front of the operator to efficiently distribute the load and provide a favourable working posture for flooring operations.
- the connecting device can be arranged at a side part of the load distribution support, such as on a side part of the waist belt or the harness, so that the hose can be carried at the hip of the operator while the flexible tube and the rigid tube can extend in the front of the operator to provide efficient load distribution and a favourable working posture.
- the connector can be connected to the hose through a swivel, so that the connector is rotatable around the hose. Hence, adverse effects due to forces applied on the connector by the hose can be avoided when the hose is positioned and moved around at a building site or similar.
- the connector can be displaceable along the hose. Hence, the connector can be positioned at the desired position along the hose. Further, the flexible tube, the rigid tube and the foldable tubing can be removed, e.g. intentionally or due to disorders, wherein the connector can be positioned correctly and be connected to the load distribution support while the hose is arranged on the shoulder of the operator or is handled directly by the operator in another way.
- the connecting device can be arranged as a wire extending between side portions of the load distribution support, wherein the connector is displaceable along said wire.
- the wire results in increased movability of the hose and flexible tube in the lateral direction, which is particularly useful when the flexible tube is arranged over the shoulder of the operator.
- the wire can be connected to the load distribution support through quick release fasteners, such as pins, wherein the wire rapidly can be disconnected from the load distribution support in an emergency.
- the shoulder strap or both of the shoulder straps can be provided with a guide, such as a soft, bent or moulded article forming a groove, for receiving and engaging a part of the flexible tube or the hose on the shoulder of the operator. Hence, by means of the guide the flexible tube is held safely in position on the shoulder of the operator.
- the shoulder strap and/or the guide can comprise a soft and/or insulating material to reduce impact from the hose or flexible tube and insulate from cold material.
- the connector can be arranged on a handle, such as a handle arranged between the connector and the hose, wherein the hose with the connector easily can be lifted, moved and connected to the connecting device.
- the invention also relates to a system for supplying a hardening and pumpable or blowable or sprayable building material to a material application site, comprising a device as mentioned above, said device comprising a first load distribution support to be used by a first operator applying said material on the application site, wherein the system comprises a second load distribution support to be used by a second operator positioning a portion of the hose, and a tool with a connector for connection with a connecting device of the second load distribution support.

Description
- The invention relates to a device for supplying a hardening and pumpable or blowable or sprayable building material to a material application site. This type of device is, for example, used for supplying a moist, wet, liquid, semi-liquid or paste material to an application site or a surface, such as a floor, a roof or a wall structure, wherein the material hardens to form a solid surface or coating. A device according to the invention is useful for flooring, wherein a flooring material, such as a cementitious flooring material, anhydrite flooring material or similar, is supplied to a floor structure. One common type of flooring materials of this type is screed, underlayment, overlayment and other floor levelling materials. Such devices can also be used for supplying façade materials, such as rendering materials, and other types of materials, such as plaster, resin, etc. to a wall structure or other types of structures. The invention also relates to a system for supplying a hardening and pumpable or blowable building material to a material application site. The invention also relates to the use of such a device and the use of such a system.
- Flooring material, such as screed, is generally provided by means of a truck containing said flooring material. The flooring material is supplied from the truck to an application site through a hose by pumping. The pump is, for example, arranged on the truck. The hose is connected to a material supply of said truck and extends to the application site, such as into a building structure. According to the prior art the hose is handled manually by an operator to distribute the flooring material, wherein the operator carries the hose and positions a free end of the hose at the desired application site. Generally, the hose is handled manually by a first operator and a second operator, wherein the first operator handles an outlet end of the hose for application of the flooring material at the desired position, and wherein the second operator lifts and moves the hose in suitable positions between the outlet and the truck to facilitate for the first operator to position the outlet end of the hose at the desired position.
- One problem with prior art systems for supplying a flooring material to a floor structure is that the working conditions are adverse. The operators are subject to heavy loads during long periods of time. Hence, there is a need for improvement of the working conditions for the operators during supply of heavy pumpable or blowable or sprayable materials for flooring or render applications. Know prior art devices and systems are shown in
US 5 433 288 ,US 4 762 257 ,US 2010/001028 andCN 203 556 086 U . - As a result of extensive research it has been found that the working posture of a flooring operator applying flooring material on an application site according to the prior art is adverse, wherein the operator is subject to increased risk for musculoskeletal disorders, particularly in the neck and the lower back. When flooring operations are performed by a first operator handling an outlet end of a hose for supplying the flooring material, and a second operator positioning a middle portion of the hose according to the prior art, the first operator may be subject to increased risk of disorders in the neck and lower back due to forward bending in combination with heavy loads during long periods of time, wherein the second operator may be subject to increased risk of disorders in the neck, lower back and shoulders due to repetitive lifting, pulling and carrying of the hose.
- An object of the invention is to avoid the above mentioned problem of the prior art and provide a device and a system for supplying a hardening and pumpable or blowable or sprayable building material to a material application site which result in improved working conditions and reduces the risk of musculoskeletal disorders for at least one of the operators. Building materials of this type are generally heavy and often requires a heavy duty hose to be conducted a substantial distance by pumping or blowing. Hence, the combination of hose and material is heavy and cumbersome for manual handling according to the prior art.
- The present invention relates to a device for supplying a hardening and pumpable or blowable or sprayable building material to a material application site, comprising a hose for conducting said material from a material supply to an operator manually distributing said material on the application site by means of the device, the device comprises a load distribution support and a connector, wherein the load distribution support is connectable to the operator and comprises one or more connecting devices, and wherein the connector is connected to the hose and is connectable to the one or more connecting devices of the load distribution support to form an articulated connection between the support and the hose, so that the hose is supported on the operator through the articulated connection when the device is operated by the operator to distribute said material on the application site. The device according to the invention results in a favourable load distribution during operations, such as flooring operations with flooring materials in the form of screed, cementitious flooring materials, anhydrite flooring materials and similar, and improved working conditions for the operators.
- The load distribution support can comprise a waist belt and optionally one or two shoulder straps to form a harness. Such a load distribution support can quickly and easily be connected to the operator and distributes the load efficiently to the hip and shoulders of the operator.
- The device comprises a flexible tube connected to the hose. The hose can be a heavy duty hose adapted for transportation of cementitious materials, wherein the hose is quite rigid and heavy and is not easily bent or handled manually by the operator. The flexible tube can more easily be bent and carried over the shoulder of the operator than the hose. Further, the flexible tube can facilitate distribution of the material as it more easily than the hose can be bent in the desired direction. The flexible tube can be lighter and more flexible than the hose. Hence, the flexible tube results in a device which is easier and lighter to handle for the operator, which further reduces the risks of musculoskeletal disorders for the operator.
- The flexible tube can be connected to a rigid tube to be gripped and handled by the operator, wherein the flexible tube is arranged between the hose and the rigid tube. The rigid tube can be lighter than the hose. Hence, the rigid tube forms a manoeuverable part of the device, which can be directed in different directions due to the flexible tube.
- The rigid tube can be connected to a foldable tubing, such as a soft rubber tubing, to be manually folded by the operator to more easily prevent material from dripping from the device, e.g. when a pump for pumping the material or a compressor for blowing the material has been turned off and the device is to be moved to another position or location. The foldable tubing can be more flexible than the hose and the flexible tube, wherein the foldable tubing is easier to fold manually than the hose and the flexible tube. Hence, undesired drops of the hardening material on a floor structure can more easily be avoided.
- The connecting device can be arranged on a back part of the load distribution support, such as on the back part of the waist belt or on the back part of a harness. The connecting device can be arranged in a lower central part of such a harness. Hence, the hose can be connected to the back of the load distribution support, wherein the flexible tube can be arranged over the shoulder of the operator while the rigid tube is handled in front of the operator to efficiently distribute the load and provide a favourable working posture for flooring operations. Alternatively, the connecting device can be arranged at a side part of the load distribution support, such as on a side part of the waist belt or the harness, so that the hose can be carried at the hip of the operator while the flexible tube and the rigid tube can extend in the front of the operator to provide efficient load distribution and a favourable working posture.
- The connector can be connected to the hose through a swivel, so that the connector is rotatable around the hose. Hence, adverse effects due to forces applied on the connector by the hose can be avoided when the hose is positioned and moved around at a building site or similar.
- The connector can be displaceable along the hose. Hence, the connector can be positioned at the desired position along the hose. Further, the flexible tube, the rigid tube and the foldable tubing can be removed, e.g. intentionally or due to disorders, wherein the connector can be positioned correctly and be connected to the load distribution support while the hose is arranged on the shoulder of the operator or is handled directly by the operator in another way.
- The connecting device can be arranged as a wire extending between side portions of the load distribution support, wherein the connector is displaceable along said wire. The wire results in increased movability of the hose and flexible tube in the lateral direction, which is particularly useful when the flexible tube is arranged over the shoulder of the operator. Further, the wire can be connected to the load distribution support through quick release fasteners, such as pins, wherein the wire rapidly can be disconnected from the load distribution support in an emergency.
- The shoulder strap or both of the shoulder straps can be provided with a guide, such as a soft, bent or moulded article forming a groove, for receiving and engaging a part of the flexible tube or the hose on the shoulder of the operator. Hence, by means of the guide the flexible tube is held safely in position on the shoulder of the operator. The shoulder strap and/or the guide can comprise a soft and/or insulating material to reduce impact from the hose or flexible tube and insulate from cold material.
- The connector can be arranged on a handle, such as a handle arranged between the connector and the hose, wherein the hose with the connector easily can be lifted, moved and connected to the connecting device.
- The invention also relates to a system for supplying a hardening and pumpable or blowable or sprayable building material to a material application site, comprising a device as mentioned above, said device comprising a first load distribution support to be used by a first operator applying said material on the application site, wherein the system comprises a second load distribution support to be used by a second operator positioning a portion of the hose, and a tool with a connector for connection with a connecting device of the second load distribution support. Hence, an efficient system is provided, e.g. for flooring applications, wherein improved working conditions for the first and second operators are achieved.
