Solid wood wall panels Structural classification

Wall panels pictures (7 CDs) consists of walls and floors bearing system of structure. Wall both load-bearing components, also made room interval, are commonly used in residential buildings and the structure of the economy. Drawback is that the flexibility of room layout is poor, in order to overcome this shortcoming, present development is heading towards the big Bay. Wall plates and more for homes, flats, can also be used for Office buildings, schools and other public buildings. Wall-slab structure of bearing wall brick, masonry, precast or cast concrete. Floor slab for precast reinforced concrete or prestressed concrete hollow core slabs, grooved plates, solid plate; Precast and cast-overlap floor; Full-cast floors.

2 wall panels classified according to the materials and construction methods are divided into three categories.

Hybrid structure

Composite structure with brick or block wall, made of reinforced concrete or prestressed concrete slab housing. Because of its simple construction, low cost, and is a structure of wide application; But greater weight, poor earthquake-resistant properties of the wall, to improve their seismic performance, at the corner at the junction of the wall and wall both inside and outside addition reinforced concrete constructional column, also known as earthquake-resistant columns. Structural columns and floor, roof beam connection in order to enhance the integrity of the House, strength and deformation capability. When the wall such as hollow block masonry, steel inserts that are available through the holes in the block, pouring concrete in the hole formed reinforced concrete columns, increase earthquake resistance ability.

Precast structure

Precast structure with precast concrete wall panels and floor Assembly into housing structure was developed after the second world war, a structural system with higher levels of industrialization. The main advantage of commercial production, high construction efficiency, low labor strength, lighter weight, strength and deformation capacity of hybrid structure. But the cost is higher, required large hoisting transport machines, floor is not flexible enough. Wall plate with architectural features into an interior wall plates and wall plates. Wall plates are mainly used as load-bearing components, made with a single material. Wall panels are generally non-load-bearing walls, and insulation, heat insulation, waterproof function, structure is complex, made composite wall panels in a variety of materials. Wall panels by the used materials consists of concrete hollow wallboard, solid wall panels, lightweight aggregate concrete wall panels, industrial waste concrete wall plate, vibration brick wall panels. Precast structures constructed houses can give full play to the strength of connection, ensure the necessary stiffness and space key to overall performance. Ways of strengthening connections:

① to bottom wall plate and the adjacent floor out of welded steel;

② wall and slab sided slot to increase the joint transfer of shear capacity;

③ joints with concrete poured into a whole. Also adds vertical prestress in the walls, floor and wall panels into the overall connection method.

Internal force calculation: the wall panels, floor slabs and joints should be vertical and horizontal load intensity calculation. Internal force analysis of wall: the vertical load and out-plane horizontal loading when the fixed hinges at both ends of the wall supports to the roof, floors and Foundation of the vertical component is calculated; At the time of in-plane lateral loads, wall embedded in the basic calculation of the vertical cantilever structure, taking into account vertical and transverse wall work affect and effect of wall opening size.

Cast-style wall plates

Cast type wall plate wall of cast in place concrete, precast floor slab or cast structures. Main advantage is better seismic performance. Compared with the hybrid structure, plastering the walls significantly reduce, reduce labor intensity, less employment; Compare with precast structures, construction is simple, rapid development has become China's earthquake zone of multi-storey and high-rise residential forms one of the main structure. Cast of the wall plate wall materials and construction methods can be divided into internal and external wall all in-situ concrete and inner longitudinal wall and cross wall casting, exterior walls constructed of fabricated slab (called gate plug-in) or brick blocks (called gate outside the building) in two categories, cast wall Solid wood wall panels Stereotypes can be used template (template, portfolio templates, tunnel form template) using sliding mode and construction, methods of construction. Floor slabs using in-situ concrete floor slab, precast bar or plate, the floor should be made continuously, to improve the integrity of the House. Water the outer masonry wall structure should be built outside the walls, poured concrete walls after to ensure internal and external wall well.

Calculation of internal forces: under vertical loads, horizontal area of the wall section ratio distribution of internal forces. When horizontal loads, outer longitudinal wall flange can be used as wall as part of calculating graphics can be reduced to the framework, cross wall wall as columns, beams as beam of the cross wall, floor hinge series, distribution according to work together all transverse wall horizontal force calculation. When horizontal loads, transverse wall work, structure lengthwise by vertical and horizontal wall space structure system work together, compute graphics can be reduced to a composite frame made up of Interior and exterior wall, outer longitudinal wall beams as beam, longitudinal wall of wall and cross wall columns. If the wall material is not the same as wall thickness should be outside, interior wall material modulus ratio to be converted.
