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： Provided is a building material manufacturing apparatus and a building material manufacturing method that are suitable for efficiently manufacturing a building material while suppressing clogging of a sieve portion for sieving the building raw material. The building material manufacturing apparatus of the present invention includes, for example, a sieve portion 10 and a receiving tool 30. The sieve portion 10 includes a receiving and sending sheet 11 with no sieve openings, onto which the building raw material M is dropped, and at least one sieve sheet 12 with sieve openings that is located below the sheet. The receiving and sending sheet 11 and the sieve sheet 12 can perform undulating motion, are inclined, and are arranged side by side in the inclination direction. The receiving tool 30 is for receiving the building raw material M that has passed through the sieve openings of the sieve portion 10. In the building material manufacturing method of the present invention, for example, in a state in which the receiving and sending sheet 11 and the at least one sieve sheet 12 are performing undulating motion, the building raw material M is dropped onto the receiving and sending sheet 11, moved from the receiving and sending sheet 11 onto the sieve sheet 12, subjected to sieving by the sieve sheet 12, and the portion that passes through the sieve openings of the sieve sheet 12 is accumulated on the receiving tool 30, whereby a mat with at least one layer is formed.

摘要： An object is to provide an inorganic board and a method for manufacturing the same that are suited to achieving high waterproofness.
A manufacturing method of the present invention includes first to sixth steps. The first step involves depositing a raw material on a receiving plate B1 to form a first layer L1. The second step involves pressing a first portion Ma and a second portion Mb of a raw material mat M including the first layer L1 toward the receiving plate B1 to compress the first portion Ma and the second portion Mb. The first portion Ma and the second portion Mb are one end portion and the other end portion, respectively, of the raw material mat M in a first direction D1. The third step involves depositing a raw material on the first layer L1 to form a second layer L2. The fourth step involves planarizing an exposed surface of the second layer L2. The fifth step involves curing the raw material mat M pressed between the receiving plate B1 and a pressing plate B2 to form a cured plate M′ from raw material mat M. The sixth step involves processing the first portion Ma and the second portion Mb into a first back-side joint part P1 and a first front-side joint part P2, respectively. An inorganic board X1 according to the present invention includes the first back-side joint part P1 and the first front-side joint part P2 that are high-density parts.-
