Abstract
The utility model discloses a distance piece which comprises a transverse pole support and a plurality of supporting legs which are fixed at intervals along the length direction of the transverse pole support, wherein the bending resistance section factor of the vertical direction of the transverse pole support is more than that of the horizontal direction. The utility model adopts the transverse pole support with the section shape that the height size is more than the thickness size, so the bending resistance section factor of the vertical direction of the transverse pole support is more than that of the horizontal direction, in this way, the amount of material can be greatly reduced while the equal bending resistance strength is ensured.
Description
Technical field
The utility model relates to a kind of architectural distance piece used when carrying out concrete construction.
Background technology
As a kind of construction material; the distance piece of form shown in Figure 1 is widely used in the modern architecture construction; people generally utilize this distance piece to guarantee the thickness of the topping stipulated in standard; make between template and the reinforcing bar, keep suitable distance between reinforcing bar and the reinforcing bar; make principal rod in cement concrete, be in best stressed position, and this distance piece is made usually by the reinforcing bar of circular cross-section.Because above-mentioned distance piece only bears vertical load in use, therefore adopt the reinforcing bar of circular cross-section to make to exist consumption of materials big, the defective that the material property utilization rate is low.
The utility model content
At the problem that prior art exists, it is a kind of under the prerequisite that guarantees equal enabling capabilities that the purpose of this utility model is to provide, and reduces the distance piece of material usage.
For achieving the above object, a kind of distance piece of the utility model is made of lateral strut and several supporting legs along its length direction fixed interval, and wherein, the bending resistant section coefficient of lateral strut vertical direction is greater than the bending resistant section coefficient of its horizontal direction.
Further, the cross sectional shape of described lateral strut is made of the arc-shaped side edges of the indent of two straight flanges that are parallel to each other up and down and two mutual mirror images, and the height dimension of cross sectional shape is greater than its horizontal breadth size.
Further, the cross sectional shape of described lateral strut is the ellipse that major axis is positioned at vertical direction.
Further, the cross sectional shape of described lateral strut is made of up and down arc limit and two vertical side edge of the evagination of two mutual mirror images, and the height dimension of cross sectional shape is greater than its horizontal breadth size.
Further, the cross sectional shape of described lateral strut is made of the arc-shaped side edges of the indent of the arc limit of the evagination of two mutual mirror images up and down and two mutual mirror images, and the height dimension of cross sectional shape is greater than its horizontal breadth size.
Further, described lateral strut and described supporting leg are made by steel, and welding is fixing between supporting leg and the lateral strut.
After the utility model adopts the lateral strut of height dimension greater than the cross sectional shape of gauge, make the bending resistant section coefficient of the bending resistant section coefficient of lateral strut vertical direction greater than horizontal direction, under the situation that guarantees equal flexural strength, can significantly reduce the consumption of material like this.

The specific embodiment
Figure 2 shows that the utility model distance piece embodiment 1, in this embodiment, distance piece comprises lateral strut 1 and supporting leg 2, and lateral strut 1 and supporting leg 2 are made by steel, and 5 supporting legs 2 equidistantly are weldingly fixed on the lateral strut 1 along lateral strut 1 length direction.
Shown in Fig. 3,4, the cross sectional shape of lateral strut 1 is made of the arc-shaped side edges of the indent of two straight flanges that are parallel to each other up and down and two mutual mirror images, and the height dimension of cross sectional shape is greater than its horizontal breadth size.
According to the mechanics of materials, we know, the bending resistant section coefficient of the main perpendicular direction of flexural strength of transverse bar member is relevant, promptly relevant with the vertical direction size in its cross section, the size of cross section vertical direction is big more, the bending resistant section coefficient is big more, the ability of bearing the vertical direction bending load is big more, therefore, after the utility model is designed to the shape of parallel up and down, bilateral symmetry indent by the cross sectional shape with lateral strut, both made lateral strut have big as far as possible flexural strength, used material again as few as possible, so that reduce construction cost in vertical direction.
In addition, in this embodiment, the upper and lower surface of lateral strut made the plane after, not only convenient supported reinforcing bar is fixing, also makes the support of reinforcing bar more stable.
As shown in Figure 5, in embodiment 2 of the present utility model, the cross sectional shape of lateral strut 1 is the ellipse that major axis is positioned at vertical direction, and this elliptic cross-section can reach the purpose that guarantees flexural strength, reduces material usage equally.
As shown in Figure 6, it is that arc, dual-side are the cross sectional shape of straight flange that lateral strut 1 also can adopt following, and cross section vertical direction size is greater than its horizontal direction size, thereby make the bending resistant section coefficient of the bending resistant section coefficient of its vertical direction greater than its horizontal direction, so that the assurance flexural strength, and reduce material usage.
Figure 7 shows that the 4th kind of embodiment of the utility model, in this embodiment, the cross sectional shape of lateral strut is made of the arc-shaped side edges of the indent of the arc limit of the evagination of two mutual mirror images up and down and two mutual mirror images, and the height dimension of cross sectional shape is greater than its horizontal breadth size.Adopt this cross sectional shape, can reach the purpose that guarantees flexural strength, reduces material usage equally.
Lateral strut in the utility model distance piece is except can adopting the cross sectional shape of putting down in writing in the various embodiments described above, guaranteeing under the situation of vertical direction bending resistant section coefficient greater than horizontal direction bending resistant section coefficient, also can adopt other suitable cross sectional shapes, di sopra and two vertical side edge are straight flange, bottom is the shape on arc limit, etc.
