Description

Temporary road improvement assembly

Technical Field

The utility model relates to a movable road or a movable building road, in particular to a temporary road improvement component.

Background

Safety of construction sites is an important issue. Every time work is done outdoors, there is a risk of accidents. In order to improve the safety of human beings and machines, the current state of the art is to use steel plates. However, the main disadvantage of these steel plates is that they are very slippery, especially when the plates are wet. It is not possible to climb the slope because the plate does not provide sufficient static friction under both wet and dry conditions.

In addition, the steel sheet is currently not managed in a digital element manner. Currently, steel sheets are leased to users and collected again at the end of the lease. However, it is very time consuming for the user to decide how many tablets to rent, where, and for how long.

Disclosure of Invention

In order to solve the above problems, an object of the present utility model is to provide a portable temporary road improvement assembly with a base plate to increase static friction of the portable road assembly and simplify positioning and position history of the portable road assembly.

The base plate is designed to direct a locally limited load acting on the upper side of the base plate down onto an area substantially corresponding to the surface of the base plate. The substrate plate is adapted to be disposed on a soft surface, such as grass, soil, sand, clay, and the like. The mobile roadway assembly also includes a slip resistant layer disposed on the top surface of the base slab. The base plate of the mobile road component is typically made of metal, such as steel or aluminum. The state of the art has attempted to introduce structural components, such as artificial roughness, into metals, such as tear drop designs, and the like. In the presence of moisture or clay, soil, sand, etc. contamination, slip resistance is not guaranteed despite these structural components. The inventors of the present utility model have found that the anti-slip layer provided on the upper side of the base plate and applied in an additional application step ensures the necessary anti-slip properties even if the user wears rubber boots and the mobile road assembly has to overcome a slope.

The object of the utility model is also solved by a mobile road component with a base plate which is designed to direct locally limited loads acting on its upper side down onto an area which corresponds substantially to the edge areas at least two sides of the base plate. The mobile roadway assembly includes an anti-slip layer applied to an upper surface of the base slab. The mobile road assembly is suitable for bridging road gutters, for example during civil engineering activities. Such a mobile road assembly is also referred to as a traversing slab. Typically, the edge area of the mobile road component in the longitudinal direction is above a solid surface, and the middle area of the mobile road component in the longitudinal direction is above the gutter to be bridged. The edge region may have a length of 10% to 25% of the longitudinal direction of the mobile road component. The traversing plate is typically made of a metal such as steel. In the presence of moisture or clay, soil, sand, etc., contamination, slip resistance cannot be ensured. The inventors of the present utility model have found that a slip resistant layer provided on the top surface of the base plate and applied in an additional application step provides the necessary slip resistance even if the user wears rubber boots or other shoes with a very slippery sole.

In one design, the anti-slip layer may include a cushion layer, wherein a bottom surface of the cushion layer is coupled to a top surface of the base plate. In addition, the slip resistant layer contains a spray material coupled to the top surface of the pad layer. The spray material may contain silica sand, fire dried silica sand, gravel, advanced gravel, metal, and/or plastic. The silica sand may have a particle size of 0.3mm to 1.8mm, preferably between 0.6mm and 1.2mm, more preferably between about 0.8mm and about 1.2 mm. The gravel may include diabase gravel, fine gravel, and/or fine gravel. The grit may have a particle size of about 0.5mm to about 5mm, preferably about 1mm to about 3 mm.

The cushion layer may contain an epoxy resin, in particular a 2-component epoxy resin.

An additional layer may be located between the backing layer and the substrate platen, for example, to prevent corrosion of the substrate platen. The word "coupled" should not be construed as necessarily requiring direct connection of the layers.

In another design, the anti-slip layer may include polyurethane.

In one design, the slip resistant layer may be produced using a 2-component material. The first component comprises at least silica, and/or nepheline syenite. The second component at least comprises polyamide and/or propylene glycol monomethyl ether.

In another design, the slip resistant layer or mat layer comprises a thermoplastic or thermoset plastic. The spray material may be provided in a backing layer, such as the spray material described above.

The slip resistant layer or mat may be made of a two-component material. The first component comprises at least epichlorohydrin resin, butanediol diglycidyl ether and/or benzyl alcohol. The second component comprises benzyl alcohol, isophthalamide and/or xylylenediamine.

In another design, the slip resistant layer contains, for example, aluminum and ceramic for electrical use. The layer may be applied using a twin wire arc spray process, also known as metallization or metal deposition. Two aluminum wire coils filled with ceramic oxide were placed on either side of the arc spraying machine and a voltage was applied across the two wires. These wires will arc when they approach at the gun head, melting the material. Dry compressed air is added to atomize the material and push it onto the steel surface. And as the material melts in the arc at the gun head, it begins to solidify in flight. The partially melted particles are propelled at such a speed that when they strike the substrate plate they will agglomerate together to form a rough surface. A primer layer may be disposed between the top surface of the base plate and the bottom surface of the anti-slip layer. The primer layer includes an epoxy material, such as a 2-component epoxy-based primer.

The purpose of the primer layer is to ensure that the substrate panel is prepared in such a way that the anti-slip layer adheres to the substrate panel as effectively as possible.

The mobile road component may be provided with an electronic device with an electronic data memory and an NFC radio (near field communication). The NFC radio is disposed on the base tablet and is designed to receive data via wireless signals and to transmit data stored in the data storage via wireless signals.

The object of the utility model is also solved by a mobile road assembly with a base plate and an electronic device. The base plate is designed to direct a locally limited load acting on the upper side of the base plate down onto an area substantially corresponding to the surface of the base plate. The electronic device has an electronic data memory and an NFC radio. The NFC radio is disposed on the base tablet and is adapted to receive data via wireless signals and to transfer data stored in the data storage via wireless signals.

The electronic device may be disposed in a recess on the base plate. The electronic device may be disposed within the non-slip layer, such as in a cushion layer. The electronic device may be disposed over the primer layer.

The NFC radio may communicate using RFID (radio frequency ID), for example, in the frequency range of 865 to 868 MHz. The NFC radio receives inductive energy stored in an energy storage of the electronic device. This energy is used to transmit data stored in the memory of the electronic device via wireless signals.

The electronic device may comprise a processor adapted to decode a request signal received from the NFC radio and, after decoding the request signal, to read a unique identifier of the mobile road component from the data memory and to transmit the unique identifier as an identification signal over the NFC radio. Each portable road assembly includes an electronic device having a unique Identifier (ID) for the portable road assembly stored therein. This unique identifier is sent to the RFID reader when requested by the RFID reader. The RFID reader can uniquely identify the mobile road component.

A portable road component holder adapted to access the portable road component described above is also disclosed. The mobile roadway assembly holder includes a supplemental NFC radio, such as an RFID reader, adapted to communicate with the NFC radio of the mobile roadway assembly. The mobile road component holder includes a WAN-coupled radio adapted to communicate with a remote server. The mobile road component holder also comprises positioning means adapted to determine the current position of the holder.

The portable roadway assembly holder also further includes a processor adapted to transmit a request signal to the NFC radio of a portable roadway assembly being held when the portable roadway assembly is held by the supplemental NFC radio. The processor is further adapted to decode an identification signal received from the NFC radio of the clamped portable roadway component via the supplemental NFC radio, thereby decoding the identification data of the clamped portable roadway component. The processor is adapted to receive a current position of the gripper from the positioning device. The processor is further adapted to send the current location of the holder and an identifier of the held mobile road component to a remote server over the WAN coupling radio.

In other words, the complementary NFC radio reads a unique identification code of the mobile roadway component from an electronic device of the mobile roadway component. The processor links the unique identifier of the mobile road component to the current location of the holder and sends this data to the remote server. This may enable software running on the processor of the remote server to identify where the mobile road component, the gripper deploying the vehicle, and/or where the deployment vehicle is or has arrived at a particular time. This may enable software running on the processor of the remote server to recognize the location of the mobile road component at the present time, whether it is being used, whether it is within a storage facility, etc.

This data may be used for logistical purposes by software running on the processor of the remote server, such as determining the number of portable road components deployed, such as determining where portable road components are being or have been deployed, such as determining the extent of progress of the deployment procedure, such as determining the number of portable road components that have not been deployed, properly considering the portable road components deployed, etc.

The tracking device may include a GNSS device such as GPS, galileo, or the like.

In one design, the WAN-coupled radio may employ a cellular protocol. The cellular protocols may include GSM, 3G, LTE, 5G, 6G, or other future cellular standards. In this design, the holder is coupled to a cellular modem, for example, disposed within the holder or within a vehicle to which the holder is connected.

In one design, the WAN coupling radio may utilize a local radio protocol to communicate with the complementary WAN coupling radio. The supplemental WAN coupling radio may utilize a wired communication protocol to communicate data received using a local radio protocol to the remote server. For example, the local radio protocol may be IEEE 802.11 (WLAN), bluetooth, zigBee, or the like.

In this design, the WAN-coupled radio may communicate with a local wired modem or equivalent using a local radio protocol to route data to a remote server. For example, such a design may be used within a storage facility for a mobile roadway assembly.

Detailed Description

The utility model will now be described in more detail with reference to fig. 1 and 2, wherein fig. 1 shows a mobile road assembly 100 according to a first design of the utility model, a part of a holder 200 according to the utility model and a connector 300, and fig. 2 shows a mobile road assembly 100' according to a second design of the utility model and a part of a holder 200 according to the utility model.

The mobile roadway assembly 100 according to the first design of the present utility model is adapted to be disposed on a soft surface such as grass, soil, sand, clay, and the like. The mobile roadway assembly 100' according to the second design of the present utility model is adapted for use in bridging a ditch.

Fig. 1 and 2 show a somewhat schematic view, not to scale. The spatial relationship should not be construed as limiting, but merely as an illustration of the present utility model.

The mobile roadway assembly 100,100' includes a base plate 102 with a primer layer 104 applied thereto. The primer layer 104 contains a two-component epoxy resin binder. The primer layer has a thickness of about 50 μm to about 120 μm, preferably about 80 μm to about 100 μm.

A cushion layer 106 containing a two-component epoxy resin is positioned on the primer layer 104. The backing layer 106 has a thickness of about 0.5mm to about 3mm, preferably about 0.5mm to about 1.5 mm.

A spray material 108 is positioned on the mat 106 and extends at least partially into the mat 106. The spray material 108 may comprise quartz sand or gravel. The silica sand has a particle size of 0.3mm to 1.8mm, preferably between 0.6mm and 1.2mm, more preferably between about 0.8mm and about 1.2 mm. The gravel may comprise diabase gravel. The grit may have a particle size of about 0.5mm to about 5mm, preferably about 1mm to about 3 mm.

In another design, the non-slip layer or mat 106 comprises a thermoplastic or thermoset plastic. The slip resistant layer or mat 106 may be fabricated from a bi-component material. The first component comprises at least epichlorohydrin resin, butanediol diglycidyl ether and/or benzyl alcohol. The second component comprises benzyl alcohol, isophthalamide and/or xylylenediamine. In this design, the spray material 108 may also be located in the backing layer 106.

The spray material 108 has a high static coefficient of friction and a high sliding coefficient of friction. This ensures that even if the surface of the portable road assembly 100,100 'is wet and dirty, the vehicle has sufficient static friction to be able to move over the portable road assembly 100, 100'. Furthermore, due to the high static friction coefficient and the high sliding friction coefficient, there is no risk of slipping a person even if the surface of the mobile road assembly 100,100 'is wet or dirty, even if the person wears rubber boots, and the mobile road assembly 100,100' is provided with an angle to overcome the tilting.

A recess 110 is located on the upper side of the base plate 102. An electronic device 112 is disposed, e.g., adhered, in recess 110 above primer layer 104. The electronics 112 in the recess 110 are surrounded by the cushion 106. The electronic device 112 includes an NFC antenna 114, an NFC transceiver 116, an accumulator 118, a processor 120, and a memory 122. The unique identifier of the mobile link assembly 100,100' is stored in the memory 122 of the electronic device 112. The unique identifier may be a serial number, or any other unique identifier. The NFC antenna 114 may be an RFID antenna and the NFC transceiver 116 may be an RFID transceiver. The accumulator 118 may be a capacitor that stores electrical energy extracted from the RFID signal by the NFC antenna 114. The accumulator 118 may utilize the stored energy to power the NFC transceiver 116, the processor 120, and the memory 122 with the stored energy.

The holder 200 is part of the present utility model. The holder 200 includes an NFC antenna 202, an NFC transceiver 204, a processor 206, a memory 208, a GPS sensor 210, and a cellular modem 212. The NFC antenna 202 may be an RFID antenna and the NFC transceiver 204 may be an RFID transceiver. Once the holder 200 holds the portable road assembly 100,100' in any manner known to those skilled in the art, the NFC transceiver 204 sends a request signal to the NFC antenna 114 of the portable road assembly 100 via the NFC antenna 202. The NFC transceiver 116 of the portable roadway assembly 100,100 'decodes the request signal received from the NFC antenna 114 and forwards the decoded signal to the processor 120 of the portable roadway assembly 100, 100'. The processor 120 reads the unique identifier of the portable road component 100,100' from the memory 122 of the portable road component 100,100' and forwards the unique identifier to the NFC transceiver 116 of the portable road component 100,100 '. The NFC transceiver 116 generates an identification signal that is transmitted through the NFC antenna 114 of the mobile roadway assembly 100,100' to the NFC antenna 202 of the holder 200.

The NFC transceiver 204 of the holder 200 decodes the identification signal received from the NFC antenna 202 and forwards the decoded signal to the processor 206 of the holder 200. The processor 206 receives its instructions from the memory 208. The processor 206 of the holder 200 reads the current position of the holder 200 from the GPS sensor 210 of the holder 200. In one design, the processor 206 of the holder 200 may continuously read the current position of the holder 200 from the GPS sensor 210 of the holder 200, thereby permanently tracking the position of the deployment vehicle in which the holder 200 is mounted. The processor 206 then incorporates the identifier of the portable road component 100,100' received via the identification signal into the current location of the holder 200 to form a data record and transmits the data record to a remote server via the portable cellular modem 212.

It is appreciated that the processor 206 can additionally send a timestamp with the data set attached.

It will also be appreciated that a call signal may be sent prior to the mobile road component 100,100' being lowered, thereby determining the position of the slab both when clamped and when lowered.

This may enable software running on the processor of the remote server to monitor where the mobile road component 100,100' and/or deployment vehicle on which the holder 200 is mounted is located or was located at a particular time. This enables software running on the processor of the remote server to recognize the location of the mobile road component at the present time, whether it is being used, whether it is within a storage facility, etc. Such data may be used by software running on the processor of the remote server for logistical purposes, such as determining the number of mobile road components deployed, e.g., determining the number of mobile road components not deployed, to properly account for the mobile road components deployed, determining the location of the deployment vehicle on which the gripper is mounted, etc.

A connector 300 for connecting a plurality of mobile roadway assemblies 100 according to a first design into one is shown in fig. 1. The connector 300 includes a plurality of connection assemblies 302 that can be connected by hinges 304 to enable absorbing irregularities or variations in the surface.

The connection assembly 302 includes holes 306 through which pegs 320 may be placed. The pegs 320 can extend through the spray material 108, through the backing layer 106, through the primer layer 104, and through the substrate plate 102 through holes 130 provided in the stacks and substrate plate 102. The peg 320 contains an internal structure 322 at its upper end, and the peg 320 can be pressed into the surface and against the base plate 102 by the internal structure 322.

An advantage of the present utility model is that the portable road assembly 100,100 'contains anti-slip surfaces on which vehicles and personnel can safely move even if the portable road assembly 100,100' is wet, dirty and/or must overcome a slope. The utility model further has the following advantages: the location and location history of a portable road assembly according to the utility model can be checked by software that is run on a computer remote from the portable road assembly.

The foregoing description is only of the preferred embodiments of the utility model, and it is apparent that the embodiments described are merely some, but not all, of the embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
