Abstract
The invention relates to a composite pipe, and in particular relates to a steel pipe rubber concrete member in the composite pipe. The steel pipe rubber concrete member provided by the invention comprises a steel pipe, wherein rubber concrete is filled in the steel pipe. The steel pipe rubber concrete member has the advantages that by applying waste rubber to steel pipe concrete, the steel pipe supplies hooping force to the rubber concrete, so the problem of poor compatibility between rubber particles and cement paste is solved; and due to high deformation performance of the rubber particles, the power performance of the steel pipe concrete is improved.
Description
Technical field
The present invention relates to clad pipe, relate in particular to a kind of steel pipe rubber concrete member in clad pipe.
Background technology
For a long time; the pattern of China's economic development belongs to resource-hungry; China is in the economic period of greatly developing in addition; industrial production will produce increasing solid waste-cullet, scrap rubber, urban household garbage incineration residue; therefore, recycling these solid waste has important practical significance for china natural resources saving, environmental protection.
At present, scrap rubber is applied in concrete, compare with portland cement concrete, the rubber concrete cracking resistance is good, good toughness, deformation performance is good, modulus of elasticity is low, and have lightweight, do advantages such as shrinking the sound insulation little, that coefficient of thermal expansion is low and good, heat insulation, damping.The utilization of scrap rubber meets the fundamental realities of the country of country new period China, also is conducive to simultaneously the realization that China realizes the target of resource-conserving and environment-friendly society.Because the compatibility between rubber grain and cement slurry interface is bad, causes concrete strength to descend, thereby make the application of scrap rubber in concrete be restricted.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of steel pipe rubber concrete member.
The invention provides a kind of steel pipe rubber concrete member, comprise steel pipe, be filled with rubber concrete in described steel pipe.
As a further improvement on the present invention, the closed at both ends of described steel pipe.
The invention has the beneficial effects as follows: pass through such scheme, scrap rubber is applied in concrete filled steel tube, steel pipe provides clamping force for rubber concrete, make the bad problem of rubber grain and cement slurry compatibility improve, simultaneously, because rubber grain deformation performance is good, make the concrete filled steel tube power performance be improved.
Description of drawings
Fig. 1 is a kind of steel pipe rubber concrete of the present invention element cross-section schematic diagram.
The specific embodiment
The present invention is further described below in conjunction with description of drawings and the specific embodiment.
Drawing reference numeral in Fig. 1 is: steel pipe 1; Rubber concrete 2.
As shown in Figure 1, a kind of steel pipe rubber concrete member comprises steel pipe 1, is filled with rubber concrete 2 in described steel pipe 1.
As shown in Figure 1, the closed at both ends of described steel pipe 1.
A kind of steel pipe rubber concrete member provided by the invention, application is extensive, mainly is used as compressed member, as send power transformation member, single or multiple lift industrial premises pillar, high level or Super High civilian construction post etc., also can be used as flexural member, as arch rib in highway or Urban Bridge etc.
The scrap rubber of a kind of steel pipe rubber concrete member provided by the invention is mainly derived from waste rubber goods, junked tire and waste old are simply processed, adopt normal temperature crushing up, make rubber powder or rubber grain (piece), then rubber powder or rubber grain (piece) directly are incorporated in concrete, part replaces the coarse-fine aggregate in the common steel tube concrete.Adopt the rubber grain of 4mm, keep the sandstone constant rate, employing accounts for concrete mix gross mass 0%, 5%, 10%, 20%, 30% rubber grain equal-volume replaces sandstone, concrete design strength is C30, water/binder ratio W/C is 0.43, and sand coarse aggregate ratio β s is 33%, and establishing every cubic meter of concrete mixture quality is 2400kg, benchmark match ratio, cement: water: sand: stone=453:195:578:1174=1:0.43:1.28:2.59.The steel pipe sample dimensions is D * L * t=133mm * 400mm * 4mm, wherein weld with the cover plate that is of a size of 160mm * 160mm * 6mm the bottom, after concrete filled steel tube is poured into a mould, the contraction of 2 ~ 3mm can appear, adopt high-strength mortar to polish after it solidifies, with the cover plate welding that is of a size of 160mm * 160mm.After inner concrete curing 28d, can substantially reach design strength.Under the effect of axial compression, 1 pair of inner concrete of outside steel pipe provides the hoop constraint effect, make core concrete be in the state of three dimension stress, can greatly improve its compressive strength, the inner fill concrete of while steel pipe 1, avoid steel pipe generation unstability, thereby improved the whole mechanical property of member.
A kind of steel pipe rubber concrete member provided by the invention is applied in the common steel tube concrete, partly replaces the coarse-fine aggregate in the common steel tube concrete and the composite steel tube concrete component made with scrap rubber.
The advantage of a kind of steel pipe rubber concrete member provided by the invention is:
1. overcome in the rubber concrete the bad problem of compatibility between rubber grain and aggregate;
The rubber grain is incorporated in cement concrete, because the compatibility between rubber grain and cement slurry interface is bad, causes rubber concrete intensity to descend.On the one hand, pulverized in the rubber grain that forms by junked tire and contain zinc stearate, zinc stearate is white attritive powder, and soapy feeling is arranged, and is water insoluble, and its existence can reduce the adhesion stress between rubber grain and cement mortar; On the other hand, because there are significant difference in inorganic material and organic polymer on chemical constitution and physical aspect, lack compatibility between the two, the caking property between causing both is bad.When the rubber grain mixes in concrete filled steel tube, due to the cuff invigoration effect of steel pipe to core concrete, the core rubber concrete is in the three dimension stress state, make the ability of concrete filled steel tube entire compression bearing capacity and opposing compressive strain obtain certain enhancing, thereby relative rubber concrete, steel pipe rubber concrete depression of bearing force gets more slowly;
2. due to the good deformation performance of rubber grain, make the concrete filled steel tube power performance improve, displacement ductility is improved;
Increase along with the volume of rubber grain, bending component horizontal loading-displacement curve ascent stage slope reduces gradually, the descending branch slope increases gradually, simultaneously, compares with ordinary concrete, rubber steel pipe concrete ductility factor has had raising to a certain degree, when rubber grain volume increases gradually, the relative ordinary concrete of ductility factor increases gradually, when volume reaches 30%, it is nearly 10% that ductility factor has improved, and illustrates that concrete filled steel tubular compression bending member power performance is improved preferably;
3. the extensive application of scrap rubber in concrete filled steel tube, can be recycled scrap rubber effectively, is conducive to energy conservation, preserves the ecological environment, and meets the strategic objective of sustainable development;
4. this invention easy construction, simple to operate, service behaviour is good, can be in Practical Project large-scale application.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
