Abstract

The utility model relates to a light roof boarding using channel-section steel for a frame. The utility model is characterized in that a skeleton is formed by that a steel plate cold bending channel-section steel is used as a frame, and steel framing beams are used as secondary beams; the steel framing beams are ranged in the frame at equal intervals to form grids for the two orthogonal directions of the frame and the steel framing beams; the inner parts of the grids are filled with low weight insulation blocks; the upper and the lower sides of thermal insulation material are both stuck with a steel reinforcing mesh layer and a steel plate mesh layer; the upper and the lower steel reinforcing meshes are welded into a three dimensional space mesh frame by steel reinforcing rods; the faces of the three dimensional space mesh frame are coated with cement mortar layers. Compared with similar technical products, the utility model has the advantages of light self-weight, large span, high strength, and high safety coefficient, and the utility model with an upper and a lower metal mesh layers wrapped in cement mortar has durability and good safety.

Description

Light steel light roof board

The utility model relates to a kind of light steel light roof board of making the building roof material, belongs to the building material technical field.

In industry and civilian construction, space truss structure is widespread usage in the past, but with the supporting roof panel of rack mainly be that concrete gives making sheet, this plate is from great, and heat-insulating property is poor, requires high to the ground of whole building, the weight capacity of body of wall, and construction is complicated, and the cycle is long, and comprehensive benefit is poor.

The purpose of this utility model is to overcome weak point of the prior art and provides a kind of light-duty, and intensity can satisfy collection lightweight, insulation, the waterproof of modern building requirement, and installation is simpler than the light steel light roof board of one.

The purpose of this utility model is that the following technical scheme of nationality realizes, referring to Fig. 1-3, its skeleton is that the channel-section steel that becomes with steel plate cold bending is frame (1), make secondary beam with steel structure stringer (4), steel structure stringer (4) is arranged in frame (1) moderate distance, two directions are orthogonal, form grid, filling light thermal insulation material piece (5) in each grid, on the piece, following both sides are steel mesh reinforcement (3), be welded into the three dimensions rack with the reinforcing rod that passes heat insulating material piece (5) between two-layer steel mesh reinforcement (3), on, there is expanded metal lath (2) in the outside of following steel mesh reinforcement (3), orlop (on, soffit) spray is smeared with cement mortar (6), and cement mortar sees through expanded metal lath (2) and steel mesh reinforcement (3), and the wire lath sheet is bonded in cement mortar; The two ends of steel structure stringer (4) are welded on the frame (1), and four limits of steel mesh reinforcement (3) also are welded on the frame (1), and cement mortar is filled in steel mesh reinforcement (3) and the expanded metal lath (2), form the reinforced concrete structure, and its thickness is concordant with the channel-section steel frame.

Compare with similar technology, advantage of the present utility model is:

1, big from heavy and light, span, can be directly installed on supporting node or the purlin and bear the single-direction and dual-direction load.

2, the utility model adopts three-dimensional lightweight steel construction carrying, so the intensity height has bigger margin of safety (safety factor＞3.5), this is vital to roof panel.

3, upper and lower double layer of metal net sheet bonds in cement, and metal can corrosion, bulk strength height, the durability and the safety that can improve roofing materials.

4, in the roofing construction of large span, use light steel light roof board, can reduce construction costs.

Description of drawings:

The generalized section of the light steel light roof board of Fig. 1;

The interlayer sectional drawing of the light steel light roof board of Fig. 2;

The stereochemical structure of each layer of frame section of the light steel light roof board of Fig. 3 and the schematic diagram that puts in order.

Embodiment:

Accompanying drawing 1-3 is embodiment figure of the present utility model, each member among the figure: expanded metal lath (2) is for forming the net with prismatic hole with the perpendicular vivid mouthful of horizontal drawing in back of steel plate; Steel mesh reinforcement (3) is that the reinforcing bar with φ 3-5m/m is welded into the net with grid square shape hole; Upper and lower two-layer steel mesh reinforcement (3) is welded into the three dimensions rack with the reinforcing rod (7) that passes adiabator layer (5), and the structure of steel structure stringer (4) as shown in Figure 3, the one side reinforcing bar, another side is with angle steel or the upper and lower reinforcing bar of all using, middle diagonal brace, and the summit of diagonal brace is welded on reinforcing bar and the angle steel; Heat insulating material (5) is according to designing requirement expanded pearlite rock beam, light material such as rock cotton board or polystyrene board, light material piece (5) and steel structure stringer (4) uniform thickness, add cement sand bed (6), its gross thickness and channel-section steel frame (1) uniform thickness that the spray of upper and lower steel mesh reinforcement and expanded metal lath and the superiors is smeared.
