Description

Bamboo-based composite structural board as wallboard or floor slab

Technical Field

The utility model relates to the technical field of building boards, in particular to a green building environment-friendly composite board, and specifically relates to a bamboo-based composite structural board used as a wallboard or a floor slab.

Background

The existing bamboo-based composite board design scheme comprises the following steps:

the recombinant bamboo scheme comprises the following steps: the bamboo material is re-organized and reinforced to form new bamboo material, and is produced through processing bamboo into long bamboo strips, bamboo filaments or crushing into bamboo filament bundles, drying, soaking in glue, drying to required water content, spreading in mold, high temperature and high pressure heat curing.

The bamboo winding scheme is as follows: the bamboo winding urban comprehensive pipe gallery is different from pipe galleries of steel pipes, concrete and the like which are commonly adopted, and is a novel pipe gallery which is manufactured by using bamboo as a main raw material, adopting thermosetting resin as an adhesive and adopting a winding process. Compare in the material performance with the concrete pipe gallery with bamboo winding city utility tunnel, its compressive strength is equal with C30 concrete pipe gallery intensity to satisfy city utility tunnel engineering specification requirement. Under the same buried depth and compression conditions, the bamboo-wound urban comprehensive pipe gallery has better shock resistance, anti-settling capacity, heat preservation and anti-freezing performance, corrosion resistance and the like than those of a concrete pipe gallery. In addition, the urban comprehensive pipe gallery wound by bamboo has the outstanding advantages of light weight, convenience in construction and installation, long service life, fire prevention, heat preservation, leakage resistance, corrosion resistance, geological settlement resistance, convenience in transportation, renewable resources, low carbon, environmental friendliness and the like. Test analysis results show that under the condition of burying 1 meter deep and carrying 90 tons on the ground, the maximum vertical deformation of the urban comprehensive pipe gallery wound by the bamboos is less than 1 percent and is far lower than the control standard of 3 percent, and the service life can reach more than 100 years.

The prior art has the following defects:

the recombinant bamboo scheme comprises the following steps: high glue content, complex process, high cost and poor durability. When the recombined bamboo is used for a structural member, the bearing capacity of the recombined bamboo is high, but due to the stability problem, the member cannot be too thin and too small, so that the member is large, the bearing capacity is difficult to exert, great waste is caused, and the structural cost is far higher than that of a conventional building. For example, the recombined bamboo is adopted to be made into a hollow floor slab, the upper panel can meet the bearing capacity requirement only by 1mm, but obviously, the stability, rigidity and comfort level of the recombined bamboo cannot meet the application requirement, the thickness of the recombined bamboo must not be increased at the moment, the recombined bamboo is generally required to be at least 10mm thick, the bearing capacity is far beyond the use requirement, and the manufacturing cost is greatly increased.

The bamboo winding scheme is as follows: the industrial and civil building wallboard has great influence on the construction period, the manufacturing cost, the comfort level and the quality of the house. The bamboo wrapping technique is suitable for making pipes, but is difficult to apply to building wall panels of relatively thin thickness. And the cost is higher, the process is more complicated, the field connection construction is more difficult, and the wallboard has no comprehensive advantages compared with the traditional wallboard. Especially for non-bearing walls, the building consumption is large, the cost of the traditional wallboard is low, and the wallboard is not suitable for popularization of the bamboo winding technology.

In the prior art, only the structure and the mode of assembling the bamboo rib blank are concerned, the problem of the joint connection strength of joints between the bamboo ribs is not fully considered, and the problem of the connection performance of the joints of the composite board structure is not considered, so that the possibility of the occurrence of bamboo rib disjointing, board damage and composite board collapse exists.
