Description

Novel bamboo laminated wood sandwich shear wall

Technical Field

The invention relates to a bamboo structure building in the field of constructional engineering, in particular to a novel bamboo laminated wood sandwich shear wall.

Background

At present, traditional bamboo wood shear force wall all has bearing capacity not high, the little shortcoming of rigidity, the mechanical properties of timber structure is also less than the integrated material of bamboo, traditional bamboo wood shear force wall adopts mostly to arrange the skeleton between two blocks of wallboard and passes through the form that self-tapping screw is fixed, the wallboard destroys easily when the atress, the upper portion connected mode of traditional shear force wall is connected through self-tapping screw and roof beam usually, upper portion destroys easily when the atress, bearing capacity is not high, the actual requirement of various engineerings can't be adapted to, the scope of use is narrower.

Patent No. CN 212715499U, a wood shear wall with cellular wall skeleton is proposed, through with cellular wall skeleton and outer frame attach, the front and back terminal surface that overlay panel connects outer frame and cellular wall skeleton constitutes the shear wall and bears, this shear wall's shortcoming is that the structure is complicated, need prefabricate a large amount of cellular wall skeletons, the cost is high, and this shear wall upper portion and roof beam junction destroy easily, the overlay panel easily destroys because the nail destroys, and the mechanical properties of timber structure is general, bearing capacity is weak.

Patent No. CN 211286137U, an assembled bamboo shear wall is proposed, form the skeleton through the roof beam board, the sill slab, end post and center pillar, the skeleton is connected with the anchor, the last prestressing tendons that welds of anchor, fix the steel filler plate through self tapping screw at last, bamboo offset plate and gypsum board form wholly, the shortcoming of this shear wall is that the structure is complicated, it is inconvenient to produce, can't carry out industrial production, the cost is high, and the upper portion and the roof beam junction of this shear wall are fragile, the steel filler plate of outside nail connection, bamboo offset plate and gypsum board are fragile.

To the above-mentioned circumstances that exists, it is fixed with the skeleton to provide one kind, and wallboard is cliied to two skeletons, runs through to the novel sandwich shear force wall of another skeleton from a skeleton through self-tapping screw, and the wall body part comprises the integrated material of bamboo. Make bamboo laminated wood wall body and roof beam be connected more conveniently through H shaped steel connecting piece to and compare in the nail connected mode of traditional bamboo wood shear force wall upper portion and roof beam, improved the bearing capacity of bamboo laminated wood wall body upper portion and roof beam junction. Through cliping the wallboard with two skeletons and running through to another skeleton with self-tapping screw from a skeleton, extrude the wallboard between the skeleton, improved the bearing capacity of wallboard. The novel bamboo laminated material sandwich shear wall can better adapt to actual requirements of various projects, is simple in structure, strong in rigidity and bearing capacity, low in manufacturing cost, convenient to obtain materials and good in application prospect.

Disclosure of Invention

The invention aims to provide a novel bamboo laminated material sandwich shear wall, which is used for solving the problems that the traditional bamboo shear wall is low in rigidity and weak in bearing capacity, and under the common conditions, the traditional bamboo shear wall is complex in production process and high in manufacturing cost, cannot well adapt to the actual requirements of various projects and the like.

In order to achieve the above purpose, the invention provides the following technical scheme: the utility model provides a novel bamboo laminated wood sandwich shear force wall, includes H shaped steel connecting piece and bamboo laminated wood wall body, wherein the bamboo laminated wood wall body includes skeleton, wallboard and self-tapping screw, and the skeleton includes top sill plate and vertical fossil fragments.

The vertical keel is positioned between the top and bottom beam plates, the top and bottom beam plates are mutually vertical to the vertical keel, and the top and bottom beam plates and the vertical keel are fixed into a framework by driving self-tapping screws.

The wallboard is located between the skeleton, and four angles of wallboard and four angle laminating of skeleton make skeleton and wallboard fixed into the integrated material wall body of bamboo through squeezing into self-tapping screw. Self-tapping screw is squeezed into from one of them skeleton, runs through this skeleton, wallboard and another skeleton, through self-tapping screw firmly fixed with the wallboard between the skeleton, makes the wallboard be difficult for droing through skeleton extrusion wallboard and has improved the bearing capacity and the rigidity of wallboard.

The H-shaped steel connecting piece is fixed with the bamboo laminated wood wall body into a whole through the bolts, holes are formed in the H-shaped steel connecting piece, the corresponding positions of the bamboo laminated wood wall body are punched, the bolts are inserted to enable the H-shaped steel connecting piece and the bamboo laminated wood wall body to be fixed into a whole, bearing capacity and rigidity are improved, and the H-shaped steel connecting piece is arranged above and below the bamboo laminated wood wall body.

The framework and the wallboard are both made of bamboo laminated materials, the bamboo laminated materials are superior in mechanical property, and compared with the traditional bamboo materials, various mechanical properties are remarkably improved.

Compared with the prior art, the invention has the beneficial effects that:

1. the invention overcomes the defects that the bamboo shear wall in the traditional connection mode has low bearing capacity and low rigidity, and the connection part of the upper part of the bamboo shear wall and a beam and the wallboard is easy to damage. Through with the bolt with H shaped steel connecting piece and wall body fixed for bamboo laminated wood wall body upper portion is difficult for destroying with the roof beam junction, through with the skeleton put the wallboard outside, the skeleton is fixed with self-tapping screw after cliping the wallboard, makes the difficult bucking of wallboard break away from the destruction, thereby has improved the bearing capacity and the rigidity of wall body.

2. The invention overcomes the defects of complex production process, high manufacturing cost, low safety factor and the like of the bamboo shear wall in the traditional connection mode, improves the bearing capacity and rigidity, has safe and reliable structure, can adapt to various engineering practices, and is beneficial to popularization.
