Example Embodiment
[0033] Example 1
[0034] Using fir or poplar wood as raw materials, sawn into sawn timber and dried to a moisture content of 8-10%, and further processed into three specifications of planks and wood strips (if the length of the wood is insufficient, it can be extended by finger joints):
[0035] Board 1: 50mm (width) × 25mm (height) × 1200mm (length)
[0036] Narrow wooden strip 2: 25mm(width)×25mm(height)×400mm(length)
[0037] Wide wood strip 3: 50mm(width)×25mm(height)×400mm(length)
[0038] The wooden planks and wooden strips are processed into wooden structure building slabs in the following way:
[0039] As shown in Figure 1, the two-component API glue is applied to the side of the board 1, and the amount of glue applied on one side is about 240-260g / m 2 , Adopt the lateral pressure of 1.5-2MPa during cold pressing of the splicing machine, and the cold pressing time is 50-60 minutes to obtain the upper and lower laminates respectively;
[0040] After applying two-component ...
Example Embodiment
[0044] Example 2
[0045] Using fir or poplar wood as raw materials, sawn into sawn timber and dried to a moisture content of 8-10%, and further processed into three specifications of planks and wood strips (if the length of the wood is insufficient, it can be extended by finger joints):
[0046] Board 1: 100mm (width) × 10mm (height) × 1200mm (length)
[0047] Narrow wooden strip 2: 10mm(width)×10mm(height)×800mm(length)
[0048] According to the method of Example 1, the planks 1 and the narrow wooden strips 2 are used to process the floor slab with a three-layer structure, but the middle layer only uses the narrow wooden strips 2 to be arranged in parallel at 1-2 times the spacing, and no grooves are formed.
[0049] Figure 2 is a schematic cross-sectional view of the floor slab, and its performance indicators refer to Example 1.
