Description

Technical Field

[0001] The utility model belongs to the technical field of sleeper moulds, and in particular relates to a mould for integrally forming a concrete sleeper and a spike anchor. Background Art

[0002] Concrete sleepers need to be anchored with spikes before fasteners can be installed and rails can be fixed. At present, the method of anchoring spikes on sleepers usually involves first forming the sleepers, reserving anchor holes when forming the sleepers, and then using insulating anchors to install and fix the spikes in the anchor holes. The disadvantages of this method of anchoring spikes on sleepers are: 1) It involves operations such as installing anchor frames, grouting, inserting spikes, removing anchor frames, and cleaning anchor surfaces. The procedures are extremely cumbersome and consume a lot of manpower; 2) During online construction, due to the complex construction environment, the anchoring quality is often not up to standard due to unequal objective conditions for sleeper placement and insufficient injection of insulating anchors, thereby affecting the insulation of the sleepers;

[0003] Although pre-anchoring the spikes on the concrete sleepers can solve the above-mentioned problems caused by forming the sleepers first and then anchoring the spikes, the traditional pre-anchoring mold usually only installs the spikes on the mold. The spikes produced by the pre-anchored sleepers are in direct contact with the concrete, and the insulation of the concrete is poor. Therefore, the insulation performance of the concrete sleepers produced with pre-anchored spikes is unqualified; and when insulating concrete is used to produce pre-anchored spike sleepers, it not only increases the production cost, but also causes changes in its mechanical properties due to the addition of a large amount of insulating agent to the concrete, thereby affecting its normal use. Therefore, a mold for integrally forming the concrete sleeper and the spike anchor is developed, so that the spikes can be pre-anchored in the concrete sleeper through the insulating anchoring agent when the concrete sleeper is formed. It not only realizes the simultaneous forming of the sleeper and the spike anchoring, so as to solve a series of problems caused by the need to form the sleeper first and then anchor the spikes in the prior art, but also avoids direct contact between the spikes and the concrete, and solves the defect of decreased insulation performance of the sleeper caused by direct contact between the spikes and the concrete. Utility Model Content

[0021] The utility model arranges a spike fixing device on a sleeper mould, and arranges an isolation cylinder in the sleeper mould, and before the sleeper is formed, the spike is fixed to the mould by the spike fixing device, so that the sleeper forming and the anchoring of the spike are formed in one piece, and a series of problems caused by the sleeper being formed first and the spike being anchored later in the prior art are solved; and the arrangement of the isolation cylinder isolates the concrete of the formed sleeper from the insulating anchoring agent during the sleeper forming process, so that the insulating anchoring agent with insulating performance is coated on the outside of the spike, thereby providing insulation for the sleeper, and avoiding direct contact between the concrete and the spike, which causes unqualified insulation performance of the sleeper.
