Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asphalt mat in which a reinforcing member is arranged so as to be embedded therein, and the reinforcing member is integrally embedded inside a plate-shaped asphalt layer, and more particularly, it supports a marine structure. The present invention relates to an asphalt mat used for stably supporting on the ground.

2. Description of the Related Art When constructing an offshore structure such as a breakwater, a seawall, or a quay, a support foundation is built on the ground of the sea floor with rubble stones, etc., and the top surface of the foundation is leveled and then made of concrete A construction method such as installing a steel caisson or the like is used. Since the lower surface of a structure such as a caisson is concrete or a steel plate, there is a concern that the coefficient of friction with respect to the stone constituting the foundation is small and the caisson moves due to the influence of waves. Moreover, since the stone forming the rubble foundation is a large stone having a weight of about 100 to 300 kg, even if the upper surface thereof is flattened, there are very large irregularities, and structures such as caisson are the foundations of the foundation. When it is placed on the upper surface, it is in a state of riding on the protruding portion of the stone, so that there is a problem that it is easily affected by waves.

Therefore, in order to solve the above-mentioned problems, it is known to use an asphalt mat as disclosed in Japanese Patent Publication No. 47-45284 and the like, and the asphalt mat is arranged below the caisson. As a result, the friction resistance of the caisson to the rubble foundation can be increased. When laying the asphalt mat on a rubble foundation or when using it to prevent scouring of the foundation, configure it as large as possible to improve the efficiency of work using a crane ship. Is being considered. Therefore, asphalt mats commonly used for offshore structures have a width of 3 to
The length is 5 m, and the length is ten and several m, which is very large. In order to handle a large-sized and heavy mat, for example, as shown in Japanese Patent Publication No. 3-76368, a wire rope or the like is integrally embedded inside the mat and the wire rope is used. The method of transporting in a suspended state by a crane and laying it in the construction sea area is used.

When the above-described asphalt mat is integrally attached to the bottom surface of a large caisson or the like, as disclosed in Japanese Patent Laid-Open No. 4-194120,
After attaching mounting members such as iron wires to the mat at predetermined intervals and connecting the iron wires to the bottom rebar of the caisson,
Means such as placing concrete are used. Further, the asphalt mat is configured to have a size as large as possible according to the size of a structure such as a caisson, and corresponds to the bottom surface of the structure,
A structure such as a concrete caisson is constructed with a number of such mats closely arranged.

[0005]

However, in the conventional asphalt mat, since the suspenders such as wire ropes provided with the eye portions on both sides of the mat are projectingly provided, the mats are arranged side by side. In that case, the problem arises that the wire remains between the connecting portions of the mat and a gap is formed. Therefore, by cutting the wire at the end of the mat so that there is no gap between the mats, or by creating a structure such as a caisson on the mat with the wire folded on the mat. A processing method such as preventing the wire from being exposed is used. However, if the wire rope used for loading and unloading the mat is arranged at a distance of 1 m, for example, 10 ropes are used on both sides.
Since there are several lines, the problem that the processing is troublesome remains.

Further, as described above, the conventional asphalt mat is designed to be as large as possible because the construction efficiency and the like are considered as important points.
Since such a large-sized mat cannot be transported on the road, a method is used in which it is manufactured on the coast close to the construction site and transported by a crane ship or the like. Therefore,
When constructing a large-sized asphalt mat as described above, it is necessary to assemble a mat manufacturing apparatus for each construction site to manufacture a mat having an area required at the site. Even when a mat having a relatively small area is manufactured, the price of the mat is often relatively high because the entire equipment for manufacturing the mat is arranged on site.

In addition to the above-mentioned problems, when handling a conventional asphalt mat, it is necessary to hang a large size one horizontally by using a special suspender provided on a crane or the like. The cost of laying the mat is greatly affected because the corresponding hangings are manufactured. On the other hand, rubber mats used in the same way as asphalt mats have a certain size (1m x
The method of securing the required area by combining and laying the products manufactured as 2 m) at the construction site is used. When the rubber mat is used to support a marine structure such as a caisson, the fact that the size is constant does not cause a big problem.

The present invention solves the above-mentioned problems of conventional asphalt mats. The asphalt mat is constructed in a size that can be carried by a truck or the like.
It is an object of the present invention to provide a friction increasing member for a structure that can be manufactured in a factory, can be combined with a plurality of mats according to the situation of the site where it is used, and can easily perform cargo handling and the like.

[0009]

The present invention relates to an asphalt mat in which a reinforcing member is integrally embedded inside and the reinforcing member is covered with an asphalt mastic. In the present invention, a frame body that is arranged on four sides and is made up of steel members that connect the end portions to each other, and the frame body is attached to the steel member to expose the end portions to the surface of the mat member. A plurality of locked members and a mesh member integrally arranged inside the steel member are combined to form a reinforcing member, and the upper and lower surfaces of the reinforcing member and the periphery are integrally covered with asphalt mastic. It constitutes an asphalt mat. Further, in the present invention, the end reinforcing material made of steel material and a connecting member for connecting the end reinforcing material are connected to each other to form a rectangular frame body, and a net is provided inside the frame body. A member is arranged, the member to be locked is attached to the end reinforcing material or the connection member to form a reinforcing member, and the reinforcing member is positioned and arranged inside the mold,
It is also possible that the asphalt mastic is cast in a mold in which the reinforcing member is arranged and the asphalt mastic is formed into a plate shape.

Further, according to the present invention, the end reinforcing member made of steel and the connecting member for connecting the end reinforcing member are connected to each other, and the net-shaped member is arranged inside the rectangular frame to reinforce. A reinforcing member is arranged on the upper surface of the mold, in which the first layer of asphalt layer is cast, and the reinforcing member is positioned and arranged inside the mold on the first layer of asphalt layer. Then, a second layer of asphalt mastic may be cast, and the two layers of asphalt may be integrally connected. Further, in the present invention, in addition to the end reinforcing member and the connecting member, another reinforcing member can be additionally attached to the reinforcing member, and the locked member to be attached to the reinforcing member is It is also possible to provide a screw hole and insert a bolt-shaped hanger to accommodate the lifting action. In addition to the above configuration, in the present invention, a reinforcing bar is arranged inside the frame of the reinforcing member, the end of the reinforcing bar is integrally provided with the frame, and the reinforcing bar and a net-shaped member or a fiber member are arranged. However, it is also possible to provide an intermediate locked member to the reinforcing bar.

With the above-mentioned structure, in the present invention, a standard mat member can be manufactured at the factory, and a large number of mat members can be combined and used at the site where the mat member is used. Eliminates the need to install near the construction site to manufacture matte members. Further, since the mat member of the present invention is used in the field in combination with one having a certain size, by combining the mat member according to the size of the structure such as the caisson to be applied, an arbitrary size can be obtained. The part can be covered, and the mat member can be easily handled. Therefore, unlike the case of using a large-scale asphalt mat, it is not necessary to handle a large-scale one, and the weight per sheet is configured as a unit that facilitates cargo handling. It is not necessary to use equipment etc., and it is not necessary to configure the equipment with a large size.

Further, in the mat member, since a reinforcing member having high strength is integrally embedded in the asphalt layer, the mat member will not be damaged during cargo handling, and can be easily attached to a structure. Even, it can improve durability and reliability. In addition, in the present invention,
Reinforcing bars can be arranged at arbitrary intervals inside the frame with respect to the reinforcing member, and particularly when a large-sized mat member is configured, the longitudinal and lateral reinforcing members and the reinforcing bar are used together, or By arranging the reinforcing bar alone as an internal reinforcing member, it is possible to handle the work of lifting the mat. Then, by attaching the intermediate locked member to the reinforcing bar, the mounting interval of the slings on the mat is set to be narrow, so that the mat supporting action can be performed safely when performing cargo handling or mounting to the structure. It becomes possible to do it in the state.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The friction-increasing member for a structure of the present invention will be described with reference to the examples shown in the drawings. The example shown in FIG. 1 shows one example of the structure of the mat member 1. For example, when the mat member 1 is constructed to have a size that can be transported by land using a truck, the width W is 2 m and the length L is 2 m. The case where it is configured to 4 m is shown. The mat member 1 is configured by embedding a reinforcing member 10 inside an asphalt layer 2, and the reinforcing member 10 includes end reinforcing members 11 and 11a arranged on both sides of the mat member in a width direction and the end reinforcing members 11 and 11a. The connecting members 12 and 12a for connecting the end reinforcing members are mutually connected by welding or the like to form a rectangular or rectangular frame body. As described above, the net-shaped member 15 is integrally attached to the inside of the frame body formed by combining the end reinforcing member and the connecting member, so that the net-shaped member 15 can provide the reinforcing member inside the asphalt layer. Performing the action of connecting together, as in the case of conventional asphalt mats,
It acts as an internal reinforcing member and holds it so that the asphalt layer does not peel off from the mat.

The net-shaped member 15 can be composed of a net-shaped member such as a wire mesh, and the end portions of the iron wires forming the wire mesh are fixed to the end reinforcing member and the connecting member, respectively, to form a frame body. And the wire mesh are integrated. In addition, the net-like member 15 is formed by arranging iron or other linear members vertically or horizontally or obliquely with a predetermined interval at arbitrary intervals, and fixing the end portions of these linear members to the frame body. It can also be configured. In the reinforcing member 10 configured as described above, the locked members 17 used when carrying out cargo handling after completion of the mat member or when attached to a structure such as a caisson are arranged at arbitrary intervals. The locked member is fixed to each of the end reinforcing member 11 or the connecting member 12 by means such as welding at a necessary interval. As will be described later, the locked member 17 is attached to the cap nut. As described above, the member is provided with a screw hole inside, and the bolt member is locked to the locked member 17 so as to correspond to work such as cargo handling.

FIG. 2 shows a cross-sectional view taken along the vicinity of the connecting member of FIG. 1, and FIG. 3 shows a cross-sectional view near the center of the mat member in the longitudinal direction. As shown in FIGS. 2 and 3, in the mat member 1, the reinforcing member 10 is arranged inside the asphalt layer 2, and the metal member forming the reinforcing member 10 is an asphalt layer. It is used as a reinforcing member for the asphalt layer by being protected from being exposed to the outside in the state of being embedded inside Further, the locked member 17 fixed to the end reinforcing material or the connecting member is arranged such that the upper surface is exposed on the surface of the mat member, and is used for loading and unloading into the screw hole provided in the locked member 17. The bolt member and the like can be easily locked. Incidentally, a plug or the like is attached to the threaded hole of the locked member 17 at the time of manufacturing the mat so that the mat member is manufactured after a treatment for preventing foreign matter from entering.

Apart from the mat member 1 of FIG. 1, in the mat member of the present invention, as shown in FIG. 4, the inside of the frame body assembled by the end reinforcing members 11 and 11a and the connecting members 12 and 12a. In addition, the vertical reinforcing member 13 and the horizontal reinforcing member 14
Can be respectively arranged to improve the strength of the frame. In the example shown as the mat member 1a shown in FIG. 4, when the mat member has a large size or a large weight,
Alternatively, it is applied when it is necessary to increase the number of fixing members using the locked members in order to attach to the structure. The locked member 1 is attached to each of the end reinforcing member, the connecting member, the vertical reinforcing member, and the horizontal reinforcing member that form the frame body.
7 ... are attached at predetermined intervals, and when hoisting using the bolt members of the lifting tool, etc., the load carried by each bolt member is evenly distributed, and local stress is applied to the mat member. Be able to prevent it from happening. Also, with respect to the frame body shown in FIG. 4, the net-like member is integrally attached and the net-like member 15 is integrally attached, so that the net-like member 15 is a reinforcing member inside the asphalt layer. And the mat member 1 as in the case of the mat member 1 described above. The reinforcing member acts as an internal reinforcing member, and is held so that the asphalt layer is not peeled from the mat. To do.

As described above, the reinforcing member 10 is embedded in the asphalt layer, and the mat member 1 is provided.
Alternatively, in the case of configuring 1a, since the connecting members 12 and 12a arranged in the width direction of the mat and the members such as the vertical reinforcing member 13 and the horizontal reinforcing member 14 are not used as members corresponding to a relatively large stress. , Flat steel or the like. On the other hand, since the end reinforcing members 11 and 11a arranged on both sides of the mat in the width direction are arranged as members that receive a load when the mat member is lifted, a member having high strength corresponding to the weight of the mat member. To place. For example,
In the example shown in FIG. 1, as shown in FIGS. 2 and 3, an L-shaped angle member is used, and the locked member attached to the end reinforcing material is a mat member from a flat portion of the end reinforcing material. A long member that reaches the surface is used. Apart from the embodiment of FIG. 1, the mat member of the present invention is constructed by using an L-shaped steel constituting the frame body and an end reinforcing member 21 as shown in FIG. The member to be locked 1 is attached to the upper portion of the vertical flange of the end reinforcement 21 made of shaped steel.
7 is fixed and attached. In FIG. 5, the end reinforcing material 21 is arranged so as to be buried in the asphalt layer 2 so that the upper surface of the end reinforcing material 21 is not exposed on the upper surface of the mat member.
Only the upper surface of the locked member 17 is provided so as to be exposed on the surface of the mat member, and the metal end reinforcing material is protected from being affected by the outside environment.

In the example shown in FIG. 6, T is used as the end reinforcing material 22.
Shaped steel is used, and the locked member 17 is fixed to the vertical flange of the end reinforcing member 22. Also in the end reinforcing material 22, the entire T-section steel is arranged so as to be buried inside the asphalt layer, and only the tip of the locked member 17 is exposed on the surface of the mat member. Further, in the example shown in FIG. 7, the end reinforcing material 23 is made of flat steel, and can be applied to a relatively lightweight mat member. Also in the example shown in FIG. 7, the end reinforcing material 23 is embedded inside the asphalt layer, and the long locked members 17 are fixed at predetermined intervals so that the end reinforcing material 23 reaches the surface of the mat member. And place it. Further, in the example shown in FIG. 8, the end reinforcing member 24 is made of grooved steel, and in the end reinforcing member 24, the upper flange is exposed on the surface of the mat member and the screw hole 25 is formed in the upper flange. Is formed so that it can be used for work such as cargo handling. As shown in FIG. 8, even when using grooved steel, the locked member is attached to the upper flange without exposing the upper flange to the surface of the mat member, and the upper surface of the locked member is attached. It is also possible to arrange so that only the surface of the mat member is exposed.

As shown in FIGS. 5 to 8, when the end reinforcing material is formed by using various shaped steels, the end reinforcing material is combined with a connecting member as shown in FIG. The net-shaped member 15 is integrally connected to the frame body,
The mat member can be formed in a state where the entire reinforcing member is embedded in the asphalt layer. In addition, as described above, when the end reinforcing material is arranged to be buried inside the asphalt layer, when the mat member is used as a supporting member for the marine structure, the metal member forming the reinforcing member is directly attached. Since it does not come into contact with seawater, it becomes possible to prevent corrosion of the metal member and improve the durability of the mat member. Furthermore, by combining the mat member,
When it is necessary to cover a large area, wires or the like do not protrude at the end of the mat member unlike the conventional asphalt mat, so the asphalt member is directly adjacent to the mating member connecting portion. Then, the mat member can be easily connected.

Therefore, the mat members 1, 1a manufactured as described above are prefabricated asphalt mats, and it is possible to manufacture a mat member of a certain size in advance in a factory. Then, in order to meet the demand at the mat construction site, the required number of mat members will be shipped, and a predetermined number of mat members will be combined at the site to make the usage form similar to the conventional asphalt mat. Will be possible. Further, by configuring the mat member as a size that can be transported by land on a truck, for example, it is not necessary to limit the mat member manufacturing place to the construction site, and the mat member manufactured at any place can be constructed. It becomes possible to carry it to and construct it.

[0021]

Example 1 The mat member constructed as described above can be manufactured, for example, as shown in FIG. 9, and the mold 30 is assembled in the mat manufacturing yard 31, and the mat 30 is placed inside the mold 30. The reinforcing member 10 in which the end reinforcing members 11 and 11a, the connecting member 12, and the net-shaped member are combined is arranged. As described above, when the reinforcing member is arranged inside the formwork, in order to make the lower part of the reinforcing member float from the surface of the yard, for example, a block 32 ... Let When the block 32 is made of the same material as the asphalt layer, it can be integrated with the cast asphalt layer and the block can be prevented from falling off even when the mat member is laid. Further, the block may be made of rubber or any other material having any size, but it is preferable to use a material having a property similar to that of asphalt. As described above, after the reinforcing member 10 is arranged inside the mold, an asphalt mastic is placed, so that the mold has a constant thickness so as not to press the whole inside of the mold to form a gap. To be installed. Therefore, in the inside of the formwork, the outer member of the end reinforcing material and the lower portion of the net-shaped member are filled with asphalt, and the mat member in a state in which the reinforcing member is embedded inside the asphalt mastic is formed. Manufactured.

The example shown in FIG. 10 shows an example in which an internal reinforcing member such as a glass cloth 16 is used together with the net member 15 arranged on the reinforcing member. However, there is a problem that the asphalt mastic cannot be cast at one time to manufacture a mat member. Therefore, in the example shown in FIG. 10, the first layer of asphalt layer 3 is first applied with a predetermined thickness inside the formwork 30 assembled in the mat manufacturing yard 31, and the asphalt layer below the reinforcing member is formed. Form. after,
Glass cloth 16 impregnated with asphalt component 1
Reinforcement member 1 after laying on the asphalt layer 3 of the layer
By arranging 0 and forming the asphalt layer 4 as the second layer, the mat member 1b is constituted. Therefore, the mat member 1b manufactured as described above includes the frame body of the reinforcing member and the net-like member 1 arranged inside the frame.
5, and since the reinforcing member such as the glass cloth 16 is provided, the asphalt layer can be firmly held by the reinforcing member, and even if an unexpected external force is applied at the time of loading and unloading, the asphalt can be held. Can be prevented from falling off.

The mat member manufactured as described above can be loaded and unloaded by using a lifting device such as a crane as shown in FIG. In the example shown in FIG. 11, with respect to the mat member in which the locked member is constituted by a member such as a cap nut, the suspenders 35 ... The tools 35 ... Can be attached to the locked member of the mat member and suspended. In addition, the hanging device 35 ...
Is configured such that the portion to be attached to the wire is an eye-shaped member, and the lower bolt member is configured to correspond to the screw hole formed in the locked member, and the bolt member is locked by the locked member 1
Attach to 7. Therefore, as described above, a large number of wires 36 ... Corresponding to the number of locked members arranged on the mat member are arranged at the ends of the hanging wires 37 of the crane, and the respective wires 36. Hanging device 35 at the end of
…… Attach. By adjusting the length of the wire so that the mat member can be supported horizontally, the mat member can be suspended in a horizontal state.

As the suspending tool, for example, as shown in FIG. 12, a mat member can be suspended by using a suspending frame 38. When the hanging frame 38 is used, the hanging frame 38 is supported from the hanging wire 37 of the crane through the auxiliary wire 39, and a large number of wires 36 having the same length are arranged on the hanging frame 38. Each wire 36 ……
Arrange the hanger 35 ... at the end of the. Then, as described above, when the suspension frame is used, it is possible to improve the efficiency of cargo handling as compared with the case where the suspension frame is used to suspend the frame. Further, in addition to using the hanging frame as shown in FIG. 12, when handling the mat member of the present invention, a frame body having an arbitrary shape can be used, and the mat member is sufficiently wide in the width direction. Of course, if it has a sufficient bending strength, it is of course possible to use a hanger or the like that holds it from both sides or from all sides. Further, as in the conventional asphalt mat suspension frame device, one in which the suspenders are arranged corresponding to the intervals of the locked members is used for the frame body having a size corresponding to the shape of the mat member. It is also possible.

[0025]

[Embodiment 2] As in the case of the conventional asphalt mat, the mat member constructed as shown in each of the above-mentioned embodiments is attached to a marine structure such as a caisson as a friction increasing member, or a seabed. It can be laid on the ground and used as a support member for the wave-dissipating block or a seabed ground protection member. The example shown in FIG. 13 shows an example in which a mat member is arranged on the bottom surface of the caisson 40. A large number of mat members 1 ... Are laid side by side vertically and horizontally on the seabed 41. On the surface of the mat member, connecting fittings 45 are arranged so as to project at a predetermined interval by using a locked member, and the tip end portions of the connecting fittings 45 ... Are connected to the horizontal reinforcing bars 42 of the caisson 40. In the state where concrete is cast, the connection fitting is embedded and fixed in concrete to ensure the connection with the caisson body.

Further, when the mat members are arranged side by side, if waterproofing or the like is required at the connecting portions of the respective mat members, an adhesive tape 46 or the like is arranged at the connecting portions of the mat members so that they are adjacent to each other. It is also possible to perform processing so that no gap is created between the mat members. Then, after constructing the lower reinforcing bars such as the horizontal reinforcing bars 42 and the like, the vertical reinforcing bars 43 and the like are incorporated, and concrete is placed inside the formwork to manufacture a concrete caisson. Therefore, as shown in FIG. 13, when the caisson is manufactured, the friction increasing member can be easily handled, and even if a large number of mat members are arranged side by side, the bottom surface of the caisson can be arranged. It is possible to set the adhesion of the mat member to the satisfactorily, and when the caisson is lifted, there is no problem such as the mat member falling off. In addition.
Even when the mat member is arranged on the bottom surface of a steel caisson or the like, the mat member is connected to the bottom iron plate of the steel caisson or the like by connecting a bolt-shaped member attached via a locked member. Can be integrally attached.

The example shown in FIG. 14 shows a case where a mat member is arranged on the seabed 50 or on the upper surface of a rubble foundation, and in this embodiment, as in the case of a conventional rubber mat, a predetermined mat is used. The plate-shaped mat member 1 ... of size can be laid on the laying ground with a required width in the vertical and horizontal directions. Further, in a state where the mat members are simply spread, when a problem occurs in fixing the mat members, using a means for laying asphalt mastic with a predetermined thickness on the upper surface of the mat member, or mat members, It is also possible to connect using a bolt member attached to the locked member, to bond and connect a thin sheet-shaped asphalt mastic to the joint portion of the mat member, and to use any other connection fixing means.

[0028]

Third Embodiment Apart from the above embodiment, in the present invention,
It is also possible to use means for increasing the strength of the mat member by additionally providing reinforcing bars together with the net-shaped member arranged inside the frame body made of steel. Then, in order to position and arrange the reinforcing bar at a predetermined portion of the mat member, as shown in FIG.
It is possible to use an intermediate locked member as shown in FIGS. In the example shown in FIG. 15, the intermediate locked member 51 is configured as a cylindrical member made of a material such as metal or plastic. The holes 53 are arranged so as to correspond to the bolt members of the suspending tool, and the horizontal hole 52 penetrating in the horizontal direction is provided in a predetermined portion of the cylinder so that the reinforcing bar 55 can be inserted. The intermediate locked member 51 can also be configured by attaching a pipe-shaped member for inserting a reinforcing bar to a member such as a cap nut.

In the example shown in FIG. 16, a prismatic member is shown as the intermediate engaged member 51a. In the intermediate engaged member 51a, a screw hole 53 is formed by punching from the upper portion. On the other hand, horizontal holes 52 and 52a are arranged at different heights in the lower part, and each of the horizontal holes has
Insert the reinforcing bars 55 and 56. In the embodiment shown in FIGS. 15 and 16, the screw hole 53 disposed on the upper portion of the intermediate locked member is for holding the mat member at the time of lifting by inserting and fixing the bolt member of the lifting tool. use. Further, in the example of FIG. 15, one of vertical and horizontal reinforcing bars is inserted into the horizontal hole provided in the intermediate locked member, and another orthogonal reinforcing bar 56 is bound to the reinforcing bar 55 by a binding means. Use to fix together. Furthermore, in the intermediate locked member 51a shown in FIG. 16, both of the orthogonal reinforcing bars 55 and 56 are inserted into the lateral holes 52 and 52a of the intermediate locked member, respectively, and the reinforcing bar and the intermediate locked member are inserted. The member and the mat member are integrated inside.

In addition to the example of arranging the intermediate locked member with respect to the reinforcing bar, in the frame of the reinforcing member arranged in a state of being embedded inside the mat member, the end of the reinforcing bar is reinforced at the end of the frame. It is also possible to fix it to the material by welding or the like. However, since the reinforcing member provided in the mat member uses shaped steel or the like having a relatively small size, when the end portion of the reinforcing bar is welded and fixed to the end reinforcing material or the connecting member, those steel materials May be distorted, and it may not be preferable to use the distorted frame as a reinforcing member. Therefore, in the present invention, in order to integrally provide the reinforcing member to the reinforcing member,
As shown in FIGS. 17 and 18, by inserting the reinforcing bar into the hole provided in the end reinforcing member, a means for integrating the frame body and the reinforcing bar can be configured.

The example shown in FIG. 17 shows a case where the end portion of the reinforcing bar is attached to the end reinforcing material, and the end reinforcing material 60 is arranged with the opening of the channel steel facing downward, Screw holes 61 are provided at predetermined intervals in the horizontal portion of the. Also,
Horizontal holes 62 are provided at predetermined intervals on the flange as the vertical portion of the end reinforcing material, and the reinforcing bars 55 are inserted and attached to the horizontal holes 62. Then, when attaching the end portion of the reinforcing bar 55 to the end reinforcing member 60, after inserting the reinforcing bar into the lateral hole, the end portion 55a is bent and locked, or the end portion 55 is used.
It is also possible to use a means for inserting and locking the bent state of a into the lateral hole 62 of the flange.

The example shown in FIG. 18 shows a case where the end reinforcing material 63 is made of T-shaped steel, and horizontal holes 64 are provided at a predetermined interval under the web of the end reinforcing material. I will insert the rebar so that I can fix it. Also,
A locked member 65 such as a cap nut is fixedly attached to the side portion of the T-shaped steel web so that the mat member can be suspended. The locked member 6
As shown in each of the above-described embodiments, 5 can be composed of a member having an arbitrary shape, and L having a screw hole is provided.
It can also be configured by attaching a letter-shaped plate member. Further, also in this embodiment, it is possible to use various shapes as described above as the end reinforcing material, and by providing a hole for inserting the reinforcing bar depending on the shape of the shape steel. In addition to the net-shaped member, it is possible to configure an internal reinforcing member using reinforcing bars for reinforcement.

Then, by combining the end reinforcing member and the connecting member having the above-described structure to form a frame body of the reinforcing member, arbitrary reinforcing bars are arranged vertically and horizontally inside the portion surrounded by the frame body. A reinforcing member having high strength can be configured. In addition, when the reinforcing member is fixed to the connecting member, it is assumed that the connecting member is composed of a relatively thin flat plate, so that distortion caused by welding can be easily corrected. It is possible. It is also possible to provide a hole for inserting the reinforcing bar also in the connecting member so that the end portion of the reinforcing bar is fixed and held. Therefore, if necessary, any combination of the connecting member and the reinforcing bar can be combined. The method can be adopted.

As described above, when reinforcing bars are arranged inside the frame to form a mat member having high strength, the mat member 1b as shown in FIG. 19 is manufactured. In the example shown in FIG. 19, the asphalt layer is divided into two layers as shown in FIG. 10, and the first asphalt layer 3 is first constructed, and then the reinforcing bars are integrally provided.

Since the mat member of the present invention is structured as described above, the mat member does not become very heavy like the conventional asphalt mat, and for example, it facilitates cargo handling. It is possible to configure the weight so that it can be performed. In addition, even in a factory that manufactures mat members, it is possible to easily handle the mat members such as stacking, loading on a transport vehicle, and spreading mat members at the caisson manufacturing site without using a large crane or the like. Will be possible. Further, since the mat member of the present invention can be manufactured in a factory in a standardized panel form, by stocking standard products of the mat member in the factory, it is possible to easily cope with demand, It can be easily transported from the factory away from the laying site to the site where it will be used. Therefore, it is not necessary to move the mat manufacturing equipment according to the demand, and the manufacturing cost of the mat member can be maintained constant without being affected by the situation at the site.

Further, in the mat member of the present invention, a reinforcing member having a strength capable of coping with lifting of the mat member during cargo handling is integrally embedded inside the asphalt layer, so that the strength of the mat member itself is sufficiently high. Can be configured as a large one. Due to the above-mentioned structural advantage, even when the mat member is arranged on the lower surface of the marine structure, the supporting action for the structure can be exhibited well. Further, even when the mat member is laid on the ground and used as a support member for an arbitrary structure, the mat member itself has a large strength, so that the durability and the supporting action for a heavy object can be effectively exhibited. Become. In addition, in the present invention, with respect to the reinforcing member, it is possible to arrange the reinforcing bars inside the frame body at an arbitrary interval, and particularly when configuring a large-sized mat member,
By using the vertical and horizontal reinforcing members and the reinforcing bars together, or by arranging the reinforcing bars alone as the internal reinforcing members, the work of lifting the mat can be dealt with. Then, by attaching the intermediate locked member to the reinforcing bar,
It is possible to set the attachment interval of the suspending tool to the mat narrow and to perform the supporting action of the mat in a safe state when carrying out cargo handling or attaching to the structure.
