[0077] Production Figure 1-6 A method for producing a building board, the method using Fig.14 The mold shown is made, and the specific method includes:

[0078] The panel 200 is placed face down in the placement area 6021 of the right mold 602 by a robot, and the first foaming material 201 is coated on the back of the panel 200. The bottom plate 300 is placed face down in the placement area 6011 of the left mold 601 by a robot, and the second foaming material is coated on the back of the bottom plate 300.

[0079] Two longitudinal profiles 401 and two transverse profiles 402 are vertically spliced, and angle brackets 403 are set at the connection between the longitudinal profiles 401 and the transverse profiles 402, and the longitudinal profiles 401 and the transverse profiles 402 are connected through the angle brackets 403 to obtain a rectangular frame 400;

[0080] The frame 400 is fixed around the honeycomb core 100 by an existing fixing method such as iron wire or screws, and the left mold 601 is turned to the right through the hinge 603 between the left mold 601 and the right mold 602, so that the left mold 601 is buckled on the right mold 602, and a certain pressing force is applied to the left mold 601 and the right mold 602 by the quick clamp 6022 provided on the right mold 602 to achieve compression molding. Through the compression molding method, the panel 200 is bonded to the upper end of the honeycomb core 100 through the first foaming material 201, the bottom plate 300 is bonded to the lower end of the honeycomb core 100 through the second foaming material 301, the first foaming material 201 is filled into the honeycomb hole 101 near the upper end of the honeycomb core 100 and is bonded to the hole wall of the honeycomb hole 101, and the second foaming material 301 is filled into the honeycomb hole 101 near the lower end of the honeycomb core 100 and is bonded to the hole wall of the honeycomb hole 100;

[0081] After the first foaming material 201 and the second foaming material 301 are solidified, the demoulding step of the compression molding is performed to obtain the building board 10 .

[0082] In the present method, the corner code 403 is made of plastic, which is cheap and easy to obtain, and the longitudinal profile 401 and the transverse profile 402 are made of aluminum profile, which is sturdy, durable and light in weight; preferably, a mounting groove 4011 is provided on the side wall of the longitudinal profile 401 away from the honeycomb core 100, so as to facilitate the setting of a connecting strip during splicing, and in order to enhance the fixing effect between the mounting groove 4011 and the connecting strip, a barb 4012 is provided on the groove wall of the mounting groove 4011 of the longitudinal profile 401, and the barb 4012 extends along the extension direction of the mounting groove 4011.

A robot is used to place the panel and the base plate, and the position is accurate and not easy to be misplaced. Since the molding pressure is small, there is no need to use complex molding equipment, which can greatly reduce production costs.

Place a building sheet panel horizontally upward, and place another building sheet panel vertically to the left so that the vertically placed building sheet is located above the right side portion of the horizontally placed building sheet; b. inserting the upper end of the connecting strip having a straight cross section into the mounting groove on the lower side of the vertically placed building board so that the lower end of the connecting strip extends downward in the vertical direction; Fix the connecting aluminum profile to the profile on the right side of the horizontally placed building board by self-tapping screws, install a sealing strip in the first groove of the aluminum profile, so that the outer wall on the left side of the sealing strip is in contact with and tightly pressed against the right side surface of the panel of the horizontally placed building board; c. Move the vertically placed building board downward for splicing, insert the lower end of the connecting strip into the second groove of the aluminum profile, and make the upper outer wall of the sealing strip fit and press against the lower side of the panel of the vertically placed building board; d. Apply a seam-beautifying agent to the gap between the two panels of the spliced ​​building boards; It is characterized in that The building board in step a comprises: A honeycomb core, wherein the honeycomb core has a plurality of honeycomb holes, and the axis of the honeycomb holes is perpendicular to the plane where the honeycomb core is horizontally extended; A panel, wherein the panel is bonded to the upper end of the honeycomb core through a first foaming material, wherein the first foaming material is filled into honeycomb holes near the upper end of the honeycomb core and bonded to the cell walls of the honeycomb holes; A bottom plate, wherein the bottom plate is bonded to the lower end of the honeycomb core through a second foaming material, and the second foaming material is filled into the honeycomb holes near the lower end of the honeycomb core and bonded to the hole walls of the honeycomb holes; A frame, wherein the frame is a rectangular frame, and the frame is detachably arranged around the honeycomb core and constitutes the surrounding edge of the honeycomb core. The frame is formed by vertically splicing two longitudinal profiles and two transverse profiles, and the splicing of the longitudinal profile and the transverse profile is connected by an angle code. A mounting groove is provided on the side wall of the profile away from the honeycomb core, and a barb is provided on the groove wall of the mounting groove, and the barb extends along the extension direction of the mounting groove; Before step c, the method further includes coating structural adhesive in the second groove of the aluminum profile.

2. The splicing method according to claim 1, characterized in that: The corner bracket is a plastic corner bracket, and the profile is an aluminum profile.

3. The splicing method according to claim 1, characterized in that: The upper surface of the frame is in contact with the lower surface of the panel, and the lower surface of the frame is flush with the lower surface of the bottom plate.

4. The splicing method according to claim 1, characterized in that: The first foaming material and the second foaming material are both polyurethane composite materials, which are composed of two components, one component is a hydroxyl-containing polyether, and the other component is a curing agent for polymerized diphenylmethane diisocyanate, and the mass ratio of the hydroxyl-containing polyether and the curing agent for polymerized diphenylmethane diisocyanate when mixed is 1:

1.

5. The splicing method according to claim 1, characterized in that: The panel comprises a ceramic tile, the bottom plate comprises a color steel plate, the honeycomb core is made of paper or aluminum, the weight per unit area of ​​the honeycomb core is 100 to 2500 g / ㎡, and the thickness of the honeycomb core in the up and down directions is 6 to 30 mm.
