Abstract
The utility model relates to a protective-layer spacer block for a magnetic suspension rail beam, which comprises a cement spacer block [1]. The utility model is characterized in that the cement spacer block [1] is provided with a plastic card structure, the lower half part of the plastic card is pre-buried in the cement spacer block [1], and the upper half part extends outwards from the surface of the cement spacer block [1]; the extended upper half part is composed of at least a pair of parallel elastic arms, and the inner sides of the top parts of the parallel elastic arms are provided with V-shaped inserted guide surfaces [3]. The top part of the original cement spacer block is pre-buried with the elastic plastic card structure, the cement spacer block is clamped directly on a steel bar by using the elastic plastic card structure, and therewith, the cement spacer block is fixed conveniently and reliably on the steel bar to form a protective-layer spacer block structure. The utility model can be used for the protecting-layer structure of a main span beam of traffic infrastructures, such as light rails, undergrounds, tunnels, highways, viaducts, bridge over strait bridges, etc. The utility model is characterized in that the protective-layer spacer block can be directly inserted and fixed and is not easy to disengage and displace, avoids the defect that the existing protective-layer spacer block is bound and fixed by using an iron wire through handiwork, the work efficiency is enhanced, and the installation is convenient.
Description
Technical field
The utility model relates to magnetic suspension, light rail, subway, speedway, viaduct, bridge spanning the sea etc. and strides a kind of preburied component that uses in the topping in the beam construction, is specifically related to a kind of topping cushion block structure.
Background technology
In similar traffic infrastructures of striding girder construction such as magnetic suspension rail are built; generally to build one with reinforcing bar earlier and stride beam framework; many topping cushion blocks along the skeleton outer reinforcement towards external fixation then; utilize the thickness of these cushion blocks to control protective layer thickness, mix to doubt soil with cement at last and become to stride girder construction with cage of reinforcement and topping cushion block are integrated poured.This shows; the topping cushion block is one of important component of striding the girder construction sealer; its effect is not only and is used for controlling the thickness of topping and the dimensional accuracy that guarantees the system beam, and can strengthen the topping bulk strength, prevents to crack because of vibration, impact and variations in temperature.In the known technology, light rail, subway, speedway, viaduct, bridge spanning the sea etc. are striden the beam topping and are adopted traditional spacer structure at present, will be with the iron wire colligation on reinforcing bar during use.Although such topping cushion block used for many years in the past, also can play a role, there is following defective in traditional cushion block: 1, need be fixed on the cage of reinforcement by manual colligation with iron wire, inconvenience is installed; 2, owing to adopt iron wire by manual colligation, so colligation is not firm, comes off easily, does not have protective effect; 3, the intensity of cushion block and hardness are not enough, and cracked easily, protective capacities is relatively poor.Along with developing rapidly of traffic infrastructure construction, especially key state project puts into operation, and is more and more higher to the requirement of construction quality, adopts the needs of the incompatible current development of the situation of traditional spacer structure.For this reason, the utility model is from improving the angle of structure, and the new structure that provides a kind of magnetic suspension rail etc. to stride beam topping cushion block is to overcome above-mentioned deficiency.
Summary of the invention
For achieving the above object; the technical solution adopted in the utility model is: a kind of magnetic suspension rail topping cushion block; comprise spacer; on spacer, be provided with the plastic clip structure; this plastic clip Lower Half is embedded in the spacer; the first half is protruding from the spacer surface, and the first half that stretches out is made of at least one pair of elastic arm arranged side by side, and elastic arm inside top arranged side by side is provided with V-arrangement and inserts guide surface.
The related content and the change interpretation of technique scheme are as follows:
1, in the technique scheme, described elastic arm arranged side by side specifically can adopt symmetrically arranged two elastic hook structures face-to-face, and V-arrangement inserts guide surface and is positioned at inboard, two elastic hook tops, and two bill partial parallels are opposed, establish zigzag structure on the opposed faces.
2, in the technique scheme, the quantity of described elastic arm arranged side by side can be made up of a pair of, also can be made of two pairs of arrangements, can also be made of three pairs of arrangements.Adopt the two pairs of elastic arms to arrange generally speaking and constitute, therefore best results designs not only economy like this but also can guarantee the clamping fastness.
3, in the technique scheme, described cushion block bottom side is provided with notch, and notch radially connects at cushion block.Its effect is can irritate logical by the notch seepage when casting cement, improves bond strength.
4, in order to improve cushion block self intensity, this programme cushion block can adopt C55 level intensity mortar, can use auxiliary materials such as the extremely strong cementitious additives of adhesion stress, crushed crude pearlite, high-mark cement in the mortar prescription.
The utility model principle is: the pre-buried elastoplast card structure in top at original spacer, and utilize the elastoplast card structure directly to be stuck on the reinforcing bar, with this spacer is fixed on conveniently, reliably and forms topping cushion block structure on the reinforcing bar.The utility model can be applicable on the main span beam protective layer structure of traffic infrastructures such as light rail, subway, tunnel, speedway, viaduct, bridge spanning the sea.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model is provided with the plastic clip structure that directly snaps in reinforcing bar, avoided the shortcoming of in the past fixing by manual colligation with iron wire, improved work efficiency, install easier.
2, because the utility model is provided with the plastic clip structure that directly snaps in reinforcing bar, fixing reliable at elasticity card and serrated face effect lower cushion block, be not easy generation and come off and inconsistent phenomenon, obtained effect significantly.
3, the utility model elastic arm adopts the elastic hook structure, has increased the elastic deformability, can adapt to the cage of reinforcement of multiple different-diameter.
4, the utility model is in order to improve cushion block intensity; prescriptions such as the extremely strong cementitious additives of adhesion stress, crushed crude pearlite, high-mark cement have been adopted; the plastic clip at made its top of topping cushion block can be stuck on the reinforcing bar of different thicknesses arbitrarily; characteristics such as that the bottom cushion block has is hard, antidetonation, cracking resistance, shock resistance, wear-resisting, cold-resistant, high temperature resistant, corrosion-resistant, the anti-width of cloth are penetrated, anti-aging have thoroughly changed traditional in the past cushion block shortcoming.
