Abstract

The utility model provides a member for building, which is a polyhedron; the volume weight of the polyhedron is less than that of construction material of a floor. The polyhedron provided by the utility model is embedded when the floor is cast, and the self weight of the floor can be reduced on the premise that the bending strength and the rigidity of the floor can be ensured. The utility model has the advantages of concrete saving and low cost. The improved proposal of the utility model is convenient for the layout of dark lines in a floor and a wall body.

Description

Building unit

The utility model relates to a kind of building unit, particularly can be used for the building unit of floor, body of wall.

The girderless floor of large span needs the requirement that bigger thickness satisfies flexing resistance.Because existing large span floor is the solid of being made by steel concrete, therefore deadweight is very big, is not easy to construction, and consumes a large amount of concrete, and cost is very high.

The purpose of this utility model provides a kind of building unit, and concrete is saved in the deadweight of using this building unit can alleviate floor in floor, reduces cost.

For achieving the above object, the utility model is made a polyhedron, and polyhedral unit weight is less than the proportion of floor slab structure material.During practical application, can make the polyhedron that varies in size according to the thickness of floor.During the cast floor, select sizeable polyhedron, make polyhedron can be embedded in the position, intermediate layer of floor.Like this, polyhedron is distributed in the floor, just can be made into the intermediate layer and be evenly equipped with many polyhedral floors.Because polyhedral unit weight less than the proportion of floor slab structure material, has therefore reduced the deadweight of floor.According to theory of mechanics of materials, when floor was subjected to bend, its main force part was at the upper and lower of section, the intermediate layer of floor is stressed very little, even therefore there are many cavities in the intermediate layer of floor, also can obviously not reduce the flexural strength and the rigidity of floor, its principle and i-beam structure are similar.This shows,, reduce cost as long as the polyhedron that pre-buried the utility model provides when the cast floor just can alleviate the floor deadweight, and save concrete under the prerequisite that guarantees floor flexural strength and rigidity.

The utility model has the advantages that to alleviate the deadweight of floor effectively, thereby be more convenient for floor, the particularly construction of floor prefabricated component, and also owing to the proportion of polyhedral unit weight less than the floor slab structure material, therefore the floor of making has better sound insulation property.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an appearance assumption diagram of the present utility model;

Fig. 2 is the layout plan of the utility model in floor;

The A-A sectional view of Fig. 3 Fig. 2.

Polyhedron of the present utility model can be a solid construction, also can be hollow-core construction.When making solid construction, used material proportion should be less than the proportion of floor slab structure material, for example with the material manufacturing of existing manufacturing light-weight brick.If when making hollow-core construction, used material proportion can be greater than the proportion of floor slab structure material, as long as polyhedral unit weight is less than the proportion of floor slab structure material.

Embodiment shown in Figure 1 is a hollow-core construction.Except the shape shown in the figure, can also be other shapes such as regular hexahedron, make as long as be convenient to.The big I of hollow polyhedral calculates according to the thickness and the force-bearing situation of floor, as long as make the floor of making not have excessive cavity, guarantees that floor has enough flexural strengths and rigidity to get final product.Fig. 2 shows Application Example of the present utility model, is evenly distributed with a plurality of hollow polyhedrals 2 in the floor 1 among the figure.Hollow polyhedral 2 can be used organic material such as plastics, or inorganic material such as cement mortar, or organic/inorganic composite material such as resin mortar etc. are made.

Modern architecture often needs to lay concealed wire in floor.As further improvement, referring to Fig. 3, outwardly directed interface channel 3 can be set at least one wall of hollow polyhedral 2, interface channel 3 is communicated with polyhedral hollow cavity 2a.During actual the manufacturing, can by the quantity of interface channel with towards the different hollow polyhedrals of making different size.Cast is during floor, selects the hollow polyhedral of different size for use according to the line alignment of required laying, and adjacent polyhedral interface channel is docked and connected, and all polyhedrons are communicated with and constitute wiring channels.Like this, made floor has just had interior empty passage, sunkens cord thereby need not the cutter hole.In from floor inside lead terminal head,, the cover plate 4 of removable connection can be set at least one wall of hollow polyhedral also for convenience referring to Fig. 3.During the cast floor, the polyhedron that will have covering plate structure is embedded in the place that the floor domestic demand is drawn the end of a thread, and the surface that makes cover plate expose floor, as shown in FIG..Like this, raise cover plate 4 when laying circuit, just can be easily from floor 1 inside lead head.

Can exactly the utility model be arranged in the position, intermediate layer of floor during for the ease of construction, as shown in Figure 3, the spike 5 of projection can be set on polyhedral outside wall surface.During the cast floor, spike can guarantee that the body cavity position of hollow polyhedral just in time is positioned at the position, intermediate layer of floor 1.

The utility model is equally applicable to body of wall.When being applied to body of wall, polyhedron is preferably made with solid material, bearing upper pressure, and appearance and size preferably and existing conventional building block size cooperate.Mainly be for convenience of in wiring within the walls when the utility model is applied to body of wall, be suitable for adopting hollow-core construction, and need not painstakingly hollow polyhedral to be embedded in the body of wall intermediate layer.
