Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a building support batten comprises a batten body 1, glass fibers 2 and an adhesive 3; the batten body 1 comprises a plurality of battens 10, the battens 10 are processed by a mixture of sodium hydroxide and sodium sulfite, the battens 10 are tightly attached after being pressed at a high temperature, wherein the end parts of the battens 10 on the same straight line can be spliced with each other, the end parts of two adjacent battens 10 attached with each other are not parallel and level, and any two adjacent battens 10 are bonded by an adhesive 3; the glass fiber 2 surrounds the periphery of the batten body 1, the waterproof layer 4 is wrapped and bonded on the surface of the outer layer of the glass fiber 2, and the adhesive 3 bonds the batten body 1 and the glass fiber 2.

Specifically, in the embodiment of the present invention, the battens 10 are square battens and can be stacked, before the battens 10 are extruded and attached, the battens need to be soaked in a mixture of sodium hydroxide and sodium sulfite, and then extruded at a high temperature of 100 ℃ or higher, so as to remove part of lignin in the battens 10, reduce the thickness of the battens 10, but improve the density of the battens 10, thereby improving the strength of the battens 10; the end parts of any two adjacent battens 10 which are mutually attached are not flush, so that the possibility of breakage of the joint of the front and rear adjacent battens 10 of the batten body 1 can be reduced; in order to ensure that the plurality of wood strips 10 are not scattered after being pressed and pressed, the adjacent wood strips 10 are bonded by using the adhesive 3; in order to further increase the compactness of the batten body 1, the periphery of the batten body 1 is wrapped by the glass fibers 2, the glass fibers 2 are not easy to corrode due to the nature of the glass fibers, and the waterproof layer 4 wrapped by the outer surface layer of the glass fibers 2 can protect the batten body 1 from being affected with damp, corrosion, insect pests and the like, so that the wood recycling rate in the batten is improved.

Wherein, the embodiment of the utility model provides an adhesive between the adjacent stuff adopts bonding epoxy, and the remaining adopts unsaturated polyester resin.

Further, the glass fiber 2 comprises glass fiber cloth 20 and glass fiber yarns 21, the glass fiber yarns 21 evenly cover the surface of the batten body 1 along the length direction of the batten body 1, the glass fiber cloth 20 surrounds and wraps the glass fiber yarns 21 and the batten body 1, and the adhesive 3 is filled in gaps among the glass fiber cloth 20, the glass fiber yarns 21 and the batten body 1 and is bonded with the glass fiber cloth 20, the glass fiber yarns 21 and the batten body 1. The glass fiber yarns 21 and the battens 10 are extruded together and are uniformly distributed and bonded on the outer surface of the batten body 1, the tensile strength of the batten body 1 is improved, and after the glass fiber yarns 21 and the battens 10 are extruded and bonded together, the glass fiber cloth 20 wraps and encloses the batten body 1 and the glass fiber yarns 21.

Further, the wood strips 10 on the same straight line are spliced in a finger joint mode. Through the finger joint connection mode, the capability of bearing transverse shearing force at the connection part between the end parts of the front and rear adjacent battens 10 on the same straight line can be improved, and the possibility of breaking the batten body 1 is reduced.

Further, the batten also comprises a wood reinforcing agent which is coated on the surfaces of the plurality of battens 10. Before the batten 10 is extruded, the outer surface of the batten 10 is sprayed with the wood reinforcing agent, so that micro cracks on the surface of the batten 10 can be closed, and meanwhile, the moisture-proof and corrosion-proof capabilities of the batten 10 can be improved.

Further, this flitch still includes billet 5, and billet 5 is located the four angles of flitch body 1 to pass through adhesive 3 and adhere with flitch body 1. The steel strip 5 and the battens 10 are extruded and bonded together, and are positioned at four corners of the batten body 1 after the batten body 1 is formed, and the steel strip 5 and the batten body 1 are combined to form a square structure, so that the toughness of the batten is further improved.

Further, this flitch still includes end cover 6, and end cover 6 covers the both ends of closing flitch body 1. Because the flitch is continuous long strip structure after producing, and length is too long to be unfavorable for transportation and use, generally need cut the segmentation, and the flitch is after the cutting, and flitch body 1 is in incision department and external air direct contact, and flitch body 1 is easily affected with damp, is corroded etc. in this department, so the flitch still covers at the incision both ends and closes end cover 6, protects the both ends of flitch.
