Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is used for an assembled roof structure such as a tunnel lining plate with an assembled plate, a roof for construction, a simple rockfall prevention roof and the like.

[0002]

2. Description of the Related Art Conventional techniques for joining assembled plates include a mortise joint and a hook joint in which unevenness is formed on the joint end face in addition to the butt joint. The joint method is applied together with both sides of the joint, and the joint method is used to join the joints with bolts.

[0003]

In order to form a joint by unevenness in the plate thickness of the joint end face, not only a considerable plate thickness is required, but especially in a concrete assembly plate, the joint end face has irregularities. Processing requires skill, and since the joints cannot withstand the load on the assembly plate, it is necessary to take measures to connect the connecting iron plates with bolts.

In particular, in the case of a concrete assembly plate, this not only requires a troublesome work such as fixing the bolt at a predetermined position and burying it at the time of manufacturing or drilling a bolt hole, This requires a considerable amount of time for joining at the site, so that there are drawbacks such as poor construction efficiency and high construction costs.

An object of the present invention is to improve these drawbacks of the conventional construction method, and by simple processing of the joining portion, to create the meshing of the joining surfaces of the left and right assembly plates without depending on the bolt connection of the connecting iron plates. The purpose of this is to realize a joining method that can withstand the applied load.

[0006]

In order to solve the above problems, the present invention, as shown in FIG. 1, has a protrusion 2 at the joint portion thereof, and a protrusion joint surface 3 and a protrusion. As shown in FIG. 2 and FIG. 4, using the assembly plate processed so that the left and right joint surfaces 4 and 5 of the assembly plate that sandwiches the parts have inclined cut surfaces at the same angle in mutually opposite directions. This is a process in which butt-jointing is repeated in a staggered manner, alternating left and right with respect to the center line.

[0007]

According to the method of the present invention, for example, the protrusion 2 of the right assembly plate is engaged with the recess formed by the left and right joint surfaces 4 and 5 of the left adjacent assembly plates, and the left assembly plate is formed. Also, the protrusion of will also mesh with the recess formed by the left and right joint surfaces of the right adjacent assembly plates,
Moreover, since the protrusion joint surface 3 of each assembly plate and the left and right joint surfaces 4 and 5 of the assembly plate have inclined cut surfaces having the same angle in opposite directions, the assembly plate is mounted after the assembly plate is mounted. As shown in FIG. 3, an action such as a wedge occurs against the load, and the respective assembly plates can integrally resist each other.

Further, since all the joining surfaces of the assembled plate are processed to form inclined cut surfaces at the same angle within the thickness of the assembled plate, the working is easy and thin plate joining is possible. In the case of the curved plate shown in FIG. 4, there is no problem at all.

Further, since the protruding portion joint surface 3 of the joint portion and the left and right joint surfaces 4 and 5 of the assembly plate sandwiching the protrusion portion are inclined cut surfaces having the same angle in mutually opposite directions, they are not joined. Apply the tip of the joining surface of the assembly plate to the inclined cut surface of the joining surface of the existing assembly plate, and push in the direction of the existing assembly plate, slide on the joining surface of the existing assembly plate, and easily It can be guided to the joining position.

EXAMPLE An example will be described below with reference to FIG. 2. First, the waist walls 8 and 8'are set in place by using cast-in-place concrete. On the upper surface of the waist wall, the legs 7 of the left and right assembly plates are attached. Support walls 9 and 9'for fixing 7'are constructed.

The standard width of the assembly plate is about 60 to 100 cm, and the width of the protrusion is 1/2 of that. However, the planned assembly plate 1'for both ends of the roof is a vertical half-split of the standard assembly plate. Since these materials are required, these are taken into consideration when manufacturing the assembly plate in advance.

To start assembling the roof at the site, first,
The vertical half-divided end assembly plate 1'of the standard assembly plate is brought in to a predetermined position by a construction machine such as a wrecker, and its leg portions 7'are brought into close contact with the supporting wall 9'of the waist wall 8 '. At the same time as installing, the joint portion of the assembly plate 1'is held at a predetermined height and temporarily fixed.

Next, the standard assembly plate 1 corresponding to the assembly plate 1 '
Is carried in to a predetermined position by a construction machine such as a wrecker, and its legs 7 are brought into close contact with the support wall 9 of the waist wall 8,
The joint surface 4 of the assembly plate is replaced with the protrusion joint surface 3 of the assembly plate 1 '.
When the construction machine is gradually disengaged while sliding the slanted cutting surface of No. 1, the assembly surfaces of the assembly plates 1 and 1 ′ mesh with each other,
It will come to rest in place.

By repeating such steps, the roof structure is completed as shown in FIG. 2 or FIG. 4, but in order to further strengthen the adjoining of the assembly plates, the protrusions of the assembly plates are previously prepared. It is also possible to provide a through bolt hole 6 for connecting these assembly plates at approximately the center of the portion 2 and use this for bolting.

[0015]

According to the present invention, since the complicated concavo-convex processing and the bolt connection of the iron plate for connection, which are required in the conventional method, are not required within the thickness of the joint end surface of the assembly plate, the construction cost is low. The construction efficiency can be improved, and the wedge effect due to the meshing of the joint surfaces of the assembly plate can provide resistance to the top load.
