Abstract
The utility model discloses a bolt type settlement observation mark composed of a bolt and a nut, wherein a joint spider mark is arranged at the center of the outer end surface of a bolt head. The bolt adopts an M20 stainless steel bolt. The bolt type settlement observation mark is novel in structural design, simple in machining and manufacturing and capable of ensuring the structural safety and meeting the use function. The bolt type settlement observation mark has very high material reuse efficiency, and the steel consumption is greatly reduced. In addition, few main structures are exposed (only the thickness of the nut), the bolt type settlement observation mark is not easily damaged by foreign objects, and fewer repairing works are caused. The settlement observation mark is not only suitable for the domestic power industry, but also suitable for other engineering industries at home and abroad, and has very strong applicability.
Description
Technical field
The utility model relates to a kind of settlement observation staff.
Background technology
Existing domestic power engineering construction settlement observation point adopts the making of soldering stainless steel plate or soldering stainless steel muscle mostly, and steel are many to be welded with agent structure, so material is one-time investment, is unfavorable for the recycling of material; When needs arrange a plurality of settlement observation point, need configure simultaneously identical material, cause waste to a certain degree; In addition its to expose main structure more, easily destroyed by foreign object, cause repair on the high side.
Summary of the invention
The purpose of this utility model just be to provide a kind of processing and fabricating simple, can realize the screw bolt-type settlement observation staff that material is reused, the resource recycling rate is high.
The utility model is made of bolt and nut, on the bolt head outer face of bolt, the spider sign is set.
Center, bolt head described in the utility model outer face arranges the spider sign.
Bolt described in the utility model adopts the M20 stainless steel bolt.
The utility model structural design is novel, and processing and fabricating is simple, has guaranteed safety of structure, has satisfied the use function.Have very high material and reuse efficient, greatly saved rolled steel dosage.It exposes agent structure seldom (only nut thickness) in addition, is difficult for being destroyed by foreign object, and repair is less.This settlement observation staff is not only applicable to domestic power industry, is applicable to other engineering industry of home and overseas simultaneously yet, has very strong applicability.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is side schematic view of the present utility model;
Fig. 3 is that the utility model uses constitutional diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
The utility model is made of M20 stainless steel bolt 1 and nut 2, and bolt 1 one ends are connected with nut 2 by screw thread, and bolt head 3 centers, outer face of bolt 1 arrange spider sign 4.
The utility model adopts soldering stainless steel plate or soldering stainless steel muscle for conventional settlement observation staff, can utilize the manufactured stainless steel bolt of factory (band nut) is material, with nut and agent structure welding, when needing observation, with bolt and together with the nut that welding is good in advance is screwed in, be masked as benchmark with the red spider on bolt head and observe and getting final product; When not needing to observe, bolt head can be preserved specially, and single independent body building can share a bolt head.The rotatable dismounting of bolt and nut and installation.
