Detailed Description

The invention is described in further detail below with reference to the following examples and the accompanying drawings.

The present example provides a glue-free CLT bamboo compacted wood composite board, as shown in fig. 1, the glue-free CLT bamboo compacted wood composite board includes a plurality of adhesive layers 1 with a plurality of first fiber strips 3 and a bamboo layer 2 sandwiched between two adjacent adhesive layers 1, each bamboo layer 2 is composed of bamboo strips arranged side by side, the bamboo strips of two adjacent bamboo layers 2 are arranged in a staggered manner, the plurality of first fiber strips 3 are interwoven in a grid shape, and each first fiber strip 3 is perpendicular to the bamboo strip of one adjacent bamboo layer.

The thickness of the composite board is not less than 2cm, the bamboo strips of the bamboo layer can be rotten bamboos, the bamboo strips are compacted after treatment, the compression ratio is 0.7-0.8, and the bonding layer is formed by melting a PVB resin film, soaking a first fiber strip and pressing the first fiber strip into a PVB film; the pressing method of the board is shown in fig. 2, after the first layer of bamboo strips are laid, the PVB film part with the first fiber strip and shown by BD is folded above the bamboo strips, at the moment, the second layer of bamboo strips can be vertically placed above the BD, and then the PVB film shown by C and the symmetrical position of the C is folded above the top layer of bamboo strips, at the moment, high-frequency densification can be carried out, and the composite board can be obtained after polishing after densification; the first fiber strip can adopt a fiber rope; the thickness of the bamboo strips of the bamboo layer of the present example is 0.5-2 cm; because the length directions of the bamboo strips of the two adjacent bamboo layers 2 are vertical in the example, even if the bamboo layer at the top layer of the board is irradiated by sunlight or wetted by water, the expansion or contraction of the bamboo layer can be restricted by the adjacent bamboo layer, so that the bamboo layer is not seriously deformed, rotten bamboos can be used as raw materials to achieve the purpose of waste utilization, the strength of the composite board is increased by arranging the first fiber strips, and the first fiber strips are still connected with the broken bamboo layers even if the bamboo layers are broken by external force in the using process.

This example provides a no glue CLT bamboo compacted wood composite board, as shown in fig. 4, on the basis of example 1, the compacted wood composite board further includes a second fiber strip 4, the second fiber strip 4 is located at the contact surface of two adjacent bamboo strips in the same bamboo layer 2, and the thickness of the bonding layer at the second fiber strip 4 is greater than that at the first fiber strip. The second fiber strip can adopt a hemp rope, the stitching method of the plate in the example can be to place the hemp rope between gaps of bamboo boards at the bottom layer before stitching, place a PVB film containing the first fiber strip in the example, and stack a bamboo layer formed by bamboo boards to carry out stitching, the stitching method of the plate in the example can also be to soak the hemp rope and the first fiber strip in the melted PVB film together, and the formed PVB film can be directly used.

The present example provides a bonding film for preparing a glue-free CLT bamboo pressed wood composite board, as shown in fig. 5, the bonding film comprises a resin film 30 and second fiber strips 4 inside the resin film 30, a plurality of the second fiber strips 4 are interwoven into two parallel boundary strips and a plurality of intermediate strips vertically arranged between the two boundary strips; wherein the resin film is PVB resin film, and the second fiber strip can adopt hemp rope; the distance between two adjacent middle strips is equal to the width of the bamboo board, and the width of the bamboo board is ensured to be the same when the adhesive film is used; the adhesive film of this example makes it directly put it on the bamboo clapper of bamboo layer when preparing composite board through setting up the second fibre strip, need not workman's manual work and puts, uses manpower sparingly.

The present example provides a bonding film for preparing a glue-free CLT bamboo pressed wood composite board, as shown in fig. 6, the bonding film comprises a resin film 30 and first fiber strips 3 in the resin film 30, a plurality of the first fiber strips 3 are interwoven in a grid shape, each first fiber strip 3 is perpendicular to the bamboo strips of one bamboo layer adjacent thereto; wherein the first fiber strip can adopt the nylon rope, and this example can avoid bamboo strip scattering in the compaction process through setting up the first fiber strip in the adhesive film, through the intensity that increases its composite board of preparation.

This example provides an acoustical panel made of a glue-free CLT bamboo-pressed wood composite board, as shown in fig. 7, which is different from example 1 in that the acoustical panel includes a glue-free CLT bamboo-pressed wood composite board and a sound-deadening layer 5 provided on the top surface or the bottom surface of the glue-free CLT bamboo-pressed wood composite board, a cavity 6 is provided in the sound-deadening layer 5, and a groove 7 having a saw-toothed cross section is provided on the inner bottom surface of the cavity 6.

The sound attenuation layer in the example can be directly connected with the adhesive layer through the adhesive effect of the adhesive layer, and can also be connected in other modes, and the sound attenuation layer and the adhesive layer are within the protection scope of the application; the sound-insulating layer with the cavities and the saw-tooth-shaped grooves is arranged, so that the plate has a sound-insulating effect.

The present example provides a sound-absorbing panel made of a glue-free CLT bamboo-pressed wood composite board, as shown in fig. 8 and 9, the sound-absorbing panel further comprises a connecting member 8 for connecting the composite board and the sound-absorbing layer 5, as shown in fig. 10, the connecting member 8 comprises a U-shaped connecting member 81 with a "U" shaped cross section and two connecting pieces 82 vertically arranged at the end parts of the U-shaped connecting member 81, and through grooves 9 with a "T" shaped cross section are respectively arranged on the side walls of the bamboo layer 2 and the sound-absorbing layer 5.

This example makes bamboo layer and amortization layer swing joint through setting up the connecting piece, simple to operate, and easy to detach can change when bamboo layer or amortization layer are bad.
