Description
Technical Field
The utility model belongs to the technical field of the steel strand wires, specifically be a prestressing force steel strand bundle for building.
Background
With the development of society and the continuous progress of science and technology, concrete members are important prestressed components in the building industry, and prestressed wires or steel strands are mostly used as reinforcing bars in the prestressed members in order to increase the mechanical properties of the members, such as compression resistance, earthquake resistance and the like. The quality of the bond stress between a reinforcing bar and concrete is an important factor for determining the quality of a prestressed concrete member, and meanwhile, the bond stress between the reinforcing bar and the concrete is also an important factor for improving the compression resistance and the earthquake resistance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prestressing force steel strand bundle for building to solve the problem that proposes among the above-mentioned background art.
The utility model provides a prestressing force steel strand bundles for building, includes core 1, interior steel strand layer 2, outer steel strand layer 3, interior steel strand layer 2 is twisted each other and twines outside core 1 by stranded steel wire, outer steel strand layer 3 is twisted each other and twines outside interior steel strand layer 2 by stranded steel wire, the steel wire direction of twisting of interior steel strand layer 2 is opposite with the steel wire direction of twisting of outer steel strand layer 3.
The twisting direction of the steel wires of the outer steel strand layer 3 is right twisting.
The inner steel strand layer 2 is composed of 7 strands of steel wires.
The outer steel strand layer 3 is composed of 13 strands of steel wires.
The core body 1 comprises a steel wire core and a corrugated pipe formed by spirally winding steel wires outside the steel wire core.
And the outer steel strand layer 3 is spirally wound with a spiral steel wire outer layer 4.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
the utility model discloses compact structure, convenient to use, the outer multiplicable bond strength with the concrete of steel wire through outmost spiral winding, be fit for the ground tackle gripping more, through twisting to opposite two-layer steel strand wires, make whole steel strand wires compact structure, use difficult loose, intensity is high, and lax performance is good, improves the prestressing force of steel strand wires greatly, has good economic benefits and social, suitable using widely.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention;
the labels in the figure are: a core body 1; an inner steel strand layer 2; an outer steel strand layer 3; an outer layer of spiral wires 4.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
Example 1:
the utility model provides a prestressing force steel strand bundles for building, includes core 1, interior steel strand layer 2, outer steel strand layer 3, interior steel strand layer 2 is twisted each other and twines outside core 1 by stranded steel wire, outer steel strand layer 3 is twisted each other and twines outside interior steel strand layer 2 by stranded steel wire, the steel wire direction of twisting of interior steel strand layer 2 is opposite with the steel wire direction of twisting of outer steel strand layer 3. The two layers of steel strands with opposite twisting directions ensure that the whole steel strand bundle has compact structure, difficult loosening in use, high strength and good loosening performance, greatly improves the prestress of the steel strand bundle,
the twisting direction of the steel wires of the outer steel strand layer 3 is right twisting.
The inner steel strand layer 2 is composed of 7 strands of steel wires.
The outer steel strand layer 3 is composed of 13 strands of steel wires.
Example 2
On the basis of the embodiment 1, the outer steel strand layer 3 is spirally wound with a spiral steel wire outer layer 4. The outer layer of the spiral steel wire can increase the bond stress with concrete, and is more suitable for being gripped by the anchorage device.
Example 3
On the basis of embodiment 1, the core body 1 comprises a steel wire core and a corrugated pipe in which steel wires are spirally wound outside the steel wire core.
The above description is only exemplary of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention should be considered within the scope of the present invention.
