Abstract
The invention relates to a device for fixing a surface strain gauge base on the surface of a steel structure. The device is of a door-shaped structure consisting of a transverse base fixing screw, a vertical base fixing screw, a transverse fixing screw of the surface strain gauge base, a screw nut with a washer, a slide block, a metal pad with a rubber pad, a base and a magnet. The device for fixing the surface strain gauge base on the surface of the steel structure can ensure that base distance meets the requirement on installing the surface strain gauge, avoids base sliding caused by human causes in a repeated adhesion or base welding process, reduces the intensity of monitoring personnel for installing the surface strain gauge, and has simple structure, convenient assembly and disassembly.
Description
Technical field
The present invention relates to the device that a kind of base that will be used for the surface strain meter of engineering monitoring is fixed in the iron structure surface.
Background technology
At present, to be fixed in the main method on iron structure surface be with base bonding to surface strain meter base or be welded on the iron structure surface.The process of bonding is longer than welding, but base is stronger than welding in the harmony on surface in the bonding process.No matter be the bonding base, still weld base, mainly by hand apply strength direct or indirect remove firm banking.This method of operating makes troubles not only for the monitoring personnel of on-the-spot installation surface strainometer, especially in work high above the ground installation surface strainometer, and influences the installation quality of surface strain meter base.
Summary of the invention
Be fixed in and need in the iron structure surface process to go the inconvenience that fixedly brings in order to solve existing surface strain meter base with hand, improve base installation quality and efficient, the invention provides a kind of device that surface strain meter base is fixed on the adsorbable iron structure surface on it of magnet.This stationary installation can replace the hand firm banking, reduces the fatigue strength of installing, and quantity particularly is installed more for a long time.Avoid base fixing before, slide because of hand applies the base that the strength shakiness causes.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of iron structure surface strain meter stationary installation, by base crosswise fixed screw rod, the vertical standing screw of base, base crosswise fixed screw rod, the accommodation zone washer nut, slide block, backing plate, base, magnet is formed, it is characterized in that: described slide block divides transverse slider and vertical slide block, in described transverse slider and the vertical slide block cavity that is slightly larger than base crosswise fixed screw rod and the vertical standing screw diameter of base is set respectively, transverse slider and vertical slide block are placed on base crosswise fixed screw rod and the vertical standing screw of base by the cavity in it respectively and can be free to slide, and transverse slider and vertical slide block two ends are fixed by the accommodation zone washer nut respectively; Transverse slider links to each other by interior button with vertical standing screw one end of base, and vertical slide block links to each other by interior button with base crosswise fixed screw rod one end, and base links to each other by interior button with the vertical standing screw other end of base; Described backing plate is two metal cauls with rubber blanket, hole diameter is slightly larger than base crosswise fixed screw diameter and is placed on the base crosswise fixed screw rod on the backing plate, be respectively arranged with an adjustable belt washer nut on the base crosswise fixed screw rod in two backing plate outsides, use so that metal caul clamping surface strainometer base; Described base is iron hollow cup dolly, magnet is built on the iron hollow cup dolly, by magnet suction surface strain meter stationary installation is fixed on the iron structure surface, by regulating transverse slider to adapt to surface strain different length needs, by regulating vertical slide block to adapt to the needs of base differing heights.
Wherein, help improving the fixed effect of base with the metal caul of rubber blanket.Magnet in the iron base can absorption surface strainometer stationary installation, and magnet can be adsorbed on the iron structure surface simultaneously.
The tight base of spacer plate holder, reduce vertical slide block in the position of the vertical standing screw of base up to contact iron structure surface, belt washer nut on the vertical standing screw of adjusting base suitably pressurizes, and after base is fixed by bonding or welding by the time, takes off surface strain meter base stationary installation.
The invention has the beneficial effects as follows, guarantee that the base distance satisfies the requirement of installation surface strainometer, avoid repeating to bond or welding the base that causes because of the artificial origin in the base process and slide, reduce the intensity of monitoring personnel installation surface strainometer, simple in structure, be convenient to assembly and disassembly.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the longitudinal profile structural map of first embodiment of steel construction surface strain meter stationary installation.
Fig. 2 is the transverse section structural map of first embodiment of steel construction surface strain meter stationary installation.
Among the figure: 1. base crosswise fixed screw rod, the 2. vertical standing screw of base, 3. surface strain meter base crosswise fixed screw rod, 4. transverse slider, 5. belt washer nut, 6. band rubber blanket backing plate, 7. base, 8. magnet, 9. vertical slide block.
Embodiment
In embodiment illustrated in figures 1 and 2, a kind of device that surface strain meter base is fixed on the iron structure surface of the present invention, by base crosswise fixed screw rod 1, the vertical standing screw 2 of base, surface strain meter base crosswise fixed screw rod 3, belt washer nut 5, slide block, band rubber blanket backing plate 6, base 7, magnet 8 is formed, wherein, slide block divides transverse slider 4 and vertical slide block 9, in transverse slider 4 and the vertical slide block 9 cavity that is slightly larger than base crosswise fixed screw rod 1 and vertical standing screw 2 diameters of base is set respectively, transverse slider 4 and vertical slide block 9 are placed on base crosswise fixed screw rod 1 and the vertical standing screw 2 of base by the cavity in it respectively and can be free to slide, and transverse slider 4 and vertical slide block 9 two ends are fixed by accommodation zone washer nut 5 respectively; Transverse slider 4 links to each other by interior button with vertical standing screw 2 one ends of base, and vertical slide block 9 links to each other by interior button with surface strain meter base crosswise fixed screw rod 3 one ends, and base 7 links to each other by interior button with vertical standing screw 2 other ends of base; Described backing plate 6 is two band rubber blanket backing plates, hole diameter is slightly larger than surface strain meter base crosswise fixed screw rod 3 diameters and is placed on the base crosswise fixed screw rod 3 on the backing plate 6, be respectively arranged with a scalable on the surface strain meter base crosswise fixed screw rod 3 in two backing plate 6 outsides and get belt washer nut 5, use so that metal caul 6 clamps bases; Base 7 is iron hollow cup dolly, magnet 8 is built on the iron hollow cup dolly 7, by magnet 8 suction surface strain meter stationary installation is fixed on the iron structure surface, by regulating transverse slider 4 to adapt to surface strain different length needs, by regulating vertical slide block 9 to adapt to the needs of base differing heights.To reduce the height of slide block 9,, after base 7 is fixed by bonding or welding by the time, take off surface strain meter base stationary installation by accommodation zone washer nut 5 in order to the pressure of increase surface strain meter base crosswise fixed screw rod 3.
