摘要： [Object] To provide a building material manufacturing apparatus and a building material manufacturing method each of which is suitable to vary, in a receiver width direction, a building raw material deposit amount on a building material forming receiver that receives a building raw material under a sieve portion that screens the building raw material.
[Solution] A building material manufacturing apparatus includes a sieve portion 10 and a receiver 30 that receives a building raw material M that has passed through the meshes of the sieve portion 10. The sieve portion 10 includes a series of sheets that are each capable of performing a wave motion when the apparatus is operating, that have an inclination, and that are arranged in a direction of the inclination. The series of sheets include a sieve sheet 12 and a sieve sheet 13 positioned below the sieve sheet 12. In the sieve sheet 12, meshes having an identical size are arranged at a regular pitch in a sheet width direction W. In the sieve sheet 13, meshes having two or more different sizes are arranged or a mesh region R1 and a non-mesh region R2 are arranged, in the sheet width direction W. The receiver 30 is movable below the series of sheets. The building material manufacturing method includes, by using the apparatus, forming a mat on the receiver 30, the mat including a first layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 12 and a second layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 13.

摘要： [Object] To provide a wall material and a wall-material building structure that are suitable for achieving high water resistance in the wall-material building structure.
[Solution] A wall material X of the present invention has a surface-side joint portion 10 and a rear-side joint portion 20. A first resin film 31 is provided on at least one of an end surface 11a of the surface-side joint portion 10 and an end surface 21 of the rear-side joint portion 20. A second resin film 32 is provided on at least one of an extension surface 11b and an extension surface 22b. At a splice part where the surface-side joint portion 10 of one wall material X and the rear-side joint portion 20 of another wall material X are spliced together in a first direction D1, the end surfaces 11a and 21 and the first resin film 31 are disposed such that the end surfaces 11a and 21 face each other while a gap between the end surfaces 11a and 21 is filled with at least the first resin film 31, and the extension surfaces 11b and 22b and the second resin film 32 are disposed such that the extension surfaces 11b and 22b face each other while a gap between the extension surfaces 11b and 22b is filled with at least the second resin film 32. A wall-material building structure Y of the present invention is formed by using such a wall material X.
