Abstract
The utility model relates to a high stability settling observing mark. The existing cylindrical steel body or a copper body which is provided with a mark guide hole in which an observing head is arranged and installed in converted into a column-shaped steel body or a copper body with an orthohexagonal outer edge, and at least two stopping grooves are arranged on the outer edge of the column-shaped steel body or the copper body. The utility model has the advantages of good rotation prevention property, good displacement property, small size, light weight, less consumption of steel materials or copper materials, low price, convenient site operation, etc. The actual weight of the utility model relates to one half of the original cylindrical steel body or the copper body, and the cost can be reduced for more than one third. The utility model can be used as a standard component for vertical displacement measurement.
Description
Technical field
The utility model relates to a kind of settlement observation sign, and particularly a kind of sign of burying underground that is used to detect the sedimentation situation on building masonry wall or the large-scale structures that is laid in belongs to the perpendicular displacement fields of measurement.
Background technology
In order to guarantee the safety of large-scale structures such as buildings, bridge, whether regularly detect its sedimentation situation is very important in allowed band, requirement according to the national project specifications of surveys, to multilayer and skyscraper, large bridge, dam etc. be engineering all, and all needing to distribute on the body of wall around it, it is several to tens permanent markers that are used to detect its sedimentation situation to be embedded with.Use reinforcing bar or band iron to bury sign underground in the past, the one end is embedded in the body of wall, and the other end stretches out body of wall to be used for detecting, and owing to extension had both influenced attractive in appearancely, is subjected to displacement easily again and damages, and causes observation data to be forbidden, and does not now re-use.The present settlement observation wall sign that generally uses, mainly be to be provided with on the body of wall that sign guide hole and the cylindrical steel body that is connected screw or copper body that the observation head is installed is embedded in setting height with one to form, the structure of its cylindrical steel body or copper body as shown in Figure 1, at ordinary times with the hexagon socket head cap screw plug be contained in the sign guide hole in case foreign material enter, during use, the hexagon socket head cap screw plug is taken out, pack into the connecting link of observation head in the sign guide hole and tighten with screw thread after can detect the sedimentation situation.But because the outer rim of cylindrical steel body or copper body is circular, be contained in the body of wall and still rotate easily or displacement, cause observational error, in order to prevent to rotate or displacement, increase the friction force with body of wall as far as possible, its external diameter generally need reach more than the 32MM, need to install with high-power reciprocating drill boring, exist construction inconvenient and volume is big, Heavy Weight, weak point such as steel or copper material consumption are big.
Summary of the invention
The purpose of this utility model is in order to overcome the weak point of above-mentioned wall sign, designs a kind of easy construction, volume is little, and is in light weight, and steel or copper material consumption are few, and low price can effectively prevent to rotate or the high stability settlement observation wall sign of displacement.
High stability settlement observation sign of the present utility model, comprise being provided with the sign guide hole and the cylindrical steel body that is connected screw or copper body and hexagon socket head cap screw plug that the observation head is installed that the outer rim that it is characterized in that cylindrical steel body or copper body is that regular hexagon is no less than 2 back stop slots with being provided with.
High stability settlement observation sign of the present utility model, the optimum length of its regular hexagon steel body or copper body is 70-110MM, the orthohexagonal best opposite side distance of cylindrical steel body or the external edge of copper is 22-24MM.
High stability settlement observation sign of the present utility model, because its outer rim is a regular hexagon, not only can use existing section bar but also be convenient to production and processing, with being that available water mud is embedded in the body of wall after the punching of common reciprocating drill, the anti-rotation performance is fine, also has plural back stop slot, prevent that displacement performance is good, so, can can effectively reduce its physical dimension guaranteeing to indicate under the situation of guide hole intensity, it is little to have a volume, in light weight, steel or copper material consumption are few, advantages such as low price and site operation are convenient, actual weight be about former columniform half, cost also can descend more than 1/3rd.
Description of drawings
Accompanying drawing 1 is the structural representation of former cylindrical sign; Among the figure 1 is the sign guide hole, the 2nd, connect screw, and the 3rd, cylindrical steel body or copper body, the 4th, back stop slot.
Accompanying drawing 2 is structural representations of the present utility model.
Embodiment
Referring to accompanying drawing 2,21 among the figure is sign guide holes, the 22nd, connect screw, and the 23rd, regular hexagon steel body or copper body, the 24th, back stop slot.Because its outer rim is a regular hexagon, not only can use existing section bar but also be convenient to production and processing, because it is square better naturally than circular anti-rotation performance, also has plural back stop slot, prevent that displacement performance is also better, so can effectively reduce its physical dimension, the optimum length of its regular hexagon steel body or copper body is 70-110MM, and the orthohexagonal best opposite side distance of cylindrical steel body or the external edge of copper is 22-24MM.In the actual production process, also can elect the internal diameter of sign guide hole 21 as 18MM, 12MM is selected in the aperture that connects screw 22 for use, can be easily and the supporting use of an existing observation connecting link.At ordinary times, available hexagon socket head cap screw plug is contained in the sign guide hole in case foreign material enter, because the hexagon socket head cap screw plug is identical with the structure of use at present, so do not draw in the drawings.During on-the-spot the installation, because orthohexagonal maximum opposite side distance is 24MM, its diagonal line is 25.3MM, so available diameter is the drill bit of 25MM, use the installation of can punching of common reciprocating drill, have the advantage of easy construction, simultaneously because external diameter is less, have also that volume is little, in light weight, steel or advantages such as the copper material consumption is few, low price, actual weight be about former columniform half, cost also can descend more than 1/3rd.Can do the standard component use that perpendicular displacement is measured, have very big market outlook.
Claims (2)
1, a kind of high stability settlement observation sign, comprise being provided with the sign guide hole and the cylindrical steel body that is connected screw or copper body and hexagon socket head cap screw plug that the observation head is installed that the outer rim that it is characterized in that cylindrical steel body or copper body is that regular hexagon is no less than 2 back stop slots with being provided with.
2, high stability settlement observation sign as claimed in claim 1, the optimum length that it is characterized in that described regular hexagon steel body or copper body is 70-110MM, the orthohexagonal best opposite side distance of cylindrical steel body or the external edge of copper is 22-24MM.
