In addition, the integral extruded body 2 has no sanding portion formed on the exposed surface 11.
  • the fixing bolt 3 is inserted into the fixing member accommodating portion 18 of one integral extrusion molded body.
  • the bolt 3 housed between the bolt support walls 19 of the one integrally extruded body 2 has the leg portion 3b protruding from the fixture housing groove 12 to the outside of the contact surface 10.
  • the leg portion of the bolt 3 is passed through the through hole 21 of the other integral extruded body 2.
  • the positions of the two integrally extruded bodies 2 in the extrusion direction may be shifted, but before the bolts 3 and the nuts 4 are fixed, the positions of the two integral extruded bodies 2 in the direction of extrusion are aligned. do.
  • the shift preventing portions 16 and 17 formed on the close contact surface 10 have the same cross-sectional shape in the extrusion direction, it is possible to easily align the integral extrusion molded body 2 in the extrusion direction.
  • the joint surfaces 10 are opposed to each other so that the edges 14 of the exposed surfaces 11 exposed to the outside in use are brought into close contact with each other.
  • the nut 4 is attached to the leg 3 b of the bolt 3 that has passed through the through hole 21 of the other integral extruded body 2, and the two integral extruded bodies 2 are fixed by a fixing member 30 including the bolt 3 and the nut 4.
  • the exposed surface 11 is subjected to sanding, and the sanding part 13 is integrally formed on the exposed surfaces of the two integral extrusions 2.
  • the sanding process is performed along the extrusion direction of the integrally extruded body 2, thereby making it difficult to visually recognize the boundary 9 between the integrally extruded bodies 2 from the outside.
  • the integrally extruded molded product assembly 1 of the present embodiment includes building materials, architectural handrails, crime prevention face grids, deck materials, building members such as balcony louvers, and members such as furniture, furniture, and lighting fixtures. Useful as. In particular, it is possible to conceal the boundary 9 by combining a plurality of integral extruded bodies 2 with a wide building member, and by a sanding processing portion integrally formed on the exposed surface 11 of the plurality of integral extruded bodies 2. it can. For this reason, the assembly 1 of the integrally extruded body according to the present embodiment is useful as an inexpensive wide building material.
  • a wide width can be obtained by combining a plurality of integrally extruded bodies having a coating layer provided on only a part of the metal core material.
  • An assembly of integrally molded products can be obtained. Therefore, it can be made inexpensive compared with manufacturing a wide integral extruded body.
  • the plurality of extruded molded bodies have a shape in which the edges are in close contact with each other, and the exposed surface of each integrally extruded molded body is continuous without a step between the edges during the assembly, and the coating layer is a joint surface. Since it is located only in the part, it can be fixed with sufficient strength by fixing the core material.
  • an assembly 1 of a wide integral extrusion body it can be handled by combining three or more integral extrusion bodies 2, and the assembly 1 of various width integral extrusion bodies. Can be easily formed.
  • each integral extrusion molded body at the time of the combination is a sanding portion formed integrally, the boundary between adjacent integral extrusion molded bodies is difficult to be visually recognized, and has a wide appearance. It is possible to obtain an assembly of an integrally extruded body and a building member using the assembly.
  • this invention is not limited to the said embodiment, It can implement in another various aspect.
  • the two monolithic extrusions need not have exactly the same structure, but can have different securing mechanisms.
  • the support wall 19 and the intermediate wall 20 are formed only on one integral extruded body 2 to which the bolt 3 is fixed, and the other integral extruded body 2 has a fixture storage groove. Only 12 may be formed.
