Definitions

  • the invention relates to a device for inserting a seal. active in a structure, an apparatus for inserting an active joint in a structure and a method for inserting an active joint in a structure.
  • structure means any type of road road, landing strip or other industrial paving in fluid concrete or in a malleable mineral mixture such as sand / gravel / hydraulic or hydrocarbon road binder.
  • Such a groove is advantageously formed in a soil made of a stable and perfectly calibrated material.
  • tools fitted with a narrow coulter such as those described in the document FR-A-2,687,699 or machines comprising at least minus a cylinder of horizontal axis mounted in a frame and driven by means of propulsion, the cylinder comprising at least one peripheral blade in the form of crown, as described in document FR-A-2,581,687.
  • the document FR-A-2,547,330 describes a machine for provide joints in a roadway, or a paving, comprising burial means constituted by two articulated jaws, intended to bury a joint in a strip of pavement.
  • the jaws can be controlled in open-close, they form in the state closed a housing for a joint.
  • the seal is inserted in the strip of the roadway by driving in the closed jaws.
  • Document FR-A-2,601,977 describes a device for inserting active joints in a structure, especially when the creation of a traffic lane. These measures includes a substantially shaped driving member half-disc, for the opening of a receiving trench joint, and a member for closing the trench constituted by a fork with two branches, the sinking member and the member of closure being carried by a common shaft and mounted at pivoting. This machine requires a structure made of a stable material and perfectly calibrated.
  • the object of the invention is to remedy the aforementioned drawbacks.
  • the object of the invention is achieved by a device insertion of an active joint into a structure, comprising a tool intended to form a groove for the introduction of the seal active.
  • the tool comprises a vibrator carrying a blade extending in a first direction and used to form the groove by sinking according to the first direction.
  • the vibrator also carries a series of rods substantially parallel to each other and extending in a second direction so as to be arranged in a plane perpendicular to the orientation of the blade and forming a rake.
  • the vibrator is able to activate the blade, to form the groove, in vibration according to a main component parallel to the first direction, i.e.
  • the vibrator is mounted pivoting so that the blade can be oriented alternately or the rake approximately perpendicular to the surface of the structure.
  • the principle of vibro-sinking is based on the fact that the internal shear strength of a material is strongly lowered by vibrations produced in the material.
  • the application of vibrations transmitted by the rake allows unpack the material on either side of the active joint.
  • the closing of the groove by unzipping the eastern edges essential to keep the seal in vertical position during the material compacting operation with a roller vibrant.
  • the opening and closing of the train path, and advantageously also the introduction of the active seal into the groove, are performed by a single tool. This one is designed from in such a way that we can use the same means intended to activate the vibrating tool for the blade and for the rake.
  • the vibrations necessary for the operation of the tool and the device comprising it can be generated as well by means separate from the device and connected to it by appropriate mechanical means, only by means integrated into the device.
  • the device of the invention ensures a depression efficient and fast tool in a material or structure to form the groove, thanks to the possibility of choosing the frequency and amplitude of vibrations as a function of material, or the nature of the structure, in which the joint active must be inserted.
  • the invention presents a convenience of use since there is no furrow formwork to accompany the driving blade and where the tool and the device comprising such a tool can be controlled by piloting from a cabin of an apparatus or a vehicle fitted with such a tool.
  • the shape and dimensions of the blade and the dimensions and arrangement of rods may vary depending the application of the tool or device.
  • the active joint can have different shapes and dimensions.
  • joints with a cross section approximately sinusoidal cross section show characteristics clearly superior to those of a flat joint.
  • seals with a series are used undulations with a flat at each of its ends.
  • the tool for inserting an active joint into a soil and device comprising such a tool can be mounted on a apparatus for inserting an active joint into a structure or onto a vehicle.
  • the invention also relates to an apparatus insertion of an active joint into a structure, comprising a hydraulic arm, and an insertion device as defined more high.
  • the hydraulic arm serves as toolbox.
  • such an apparatus comprises a frame having the dimensions necessary to allow the frame to step over a section of the structure, the hydraulic arm being mounted rotating on the frame.
  • This arrangement is particularly advantageous to implement an almost automatic installation of joints active, for example on an airport runway.
  • the insertion device is integrated into the suite of different machines used for construction of the track. Guided by one of the edges of the track or by any other suitable means, the device positions the tool at regular distances and orient it so as to lay the joints active regularly and thus obtain, as the case may be, a line continuous active joints or a series of parallel active joints between them and perpendicular to the axis of the runway, or both, continuous line and following, both. Besides, greater regularity of the installation, we also get better quality of work following the elimination of manual tasks for pre-marking the position of the seals and thanks to assistance with repetitive and tedious tasks such as, for example, lowering and raising the tool, tool tilt, sinking time and depth, and vibration time for closing the groove.
  • this device may consist of a vehicle comprising a hydraulic arm and a tool as defined more high. More particularly, such a vehicle is then a machine dedicated whose hydraulic arm is capable of carrying such mechanical and whose control elements are used to handle the tool according to the invention.
  • the invention further relates to a method insertion of an active joint into a structure, with opening a groove intended to receive the active joint, by vibro-sinking.
  • This process includes the steps of positioning a tool such as described above, on the structure, push the blade the tool in the structure by vibration, reassemble the blade, tilt the tool, insert an active seal in the open groove, lower the rake of the tool to push it into the structure, close the groove by vibration while raising the tool.
  • a vehicle fitted with a device according to the invention runs in the axis or along a roadway in order to lay a line of active joints or a series of active joints arranged perpendicular to the axis of the road.
  • the active seal is gripped by a clamp hydraulic part of the device tool and is maintained until its introduction into the furrow.
  • the tool now the active seal is lowered so that drive the rake stems into the road, on both sides on the other side of the groove.
  • the hydraulic clamp is opened and the tool is slowly raised by actuating the rods vibration according to an essentially horizontal component.
  • the method of the invention can be applied for the insertion of an active joint in all kinds of materials foundations such as for example compacted concrete, gravel and sands treated with hydraulic binders, soils and by-products manufacturers treated with hydraulic binders. In these cases, has a working time of the order of two to three hours depending on the workability of the material.
  • the following description is made in the assumption that the active joint is inserted vertically in a ground.
  • the invention is also applicable to a insertion of an active joint in a plane different from a plane vertical and, generally speaking, at an angle different from the right angle to the ground.
  • the device for inserting an active joint into a soil comprises a tool 1 pivotally mounted around an H axis on a stirrup 2.
  • the tool 1 is provided with a blade 3 and a plurality of rods 4 forming a rake 5.
