Description
Technical field
This utility model relates to structural connection protection device, is specially a kind of simple split type anchor bolt protective cap.
Background technology
The effect of foundation bolt fixes machinery, equipment, large scale structure or component on the ground use.Because it has stronger steadiness, apply on railway, highway, bridge, mine, power plant, electric power and the shaft tower that communicates, tower crane, boiler steel structure, large-span steel and heavy construction etc. so being frequently seen it.The making material of foundation bolt typically uses Q235 carbon structural steels, also has employing Q345 low-alloy high-tensile structural steel to make.
Foundation bolt is substantially made up of the section of appearing and anchoring section two parts.The section of appearing, is i.e. exposed to the part of basis end face, including bolt, nuts and washers three part.Anchoring section i.e. buried foundation or under ground portion.According to anchoring section stud base's shape and structure, foundation bolt can be divided into L-type foundation bolt, J-type foundation bolt, ratchet-type foundation bolt and T-shaped foundation bolt (i.e. strap bolt connects foundation bolt and the foundation bolt of welding anchor slab of anchor slab) etc..
In order to ensure anchor force enough between foundation bolt and basis, prevent foundation bolt to be pulled out and cause equipment or connection loosing, shift or topple, the requirement being provided with buried depth and angle of foundation bolt.Type and the type of foot bolt fastening basic material and intensity bottom base area foot bolt raw material intensity, foundation bolt diameter, foundation bolt, foundation bolt has the different sections of appearing and anchoring depth.Conventional foundation bolt segment length of appearing is 25mm ~ 440mm, and anchoring depth is 60mm ~ 4900mm.
As structure or the important anchorage element of equipment, the design service life of foundation bolt is usually quite length, generally requires and reach decades.But, foundation bolt is after mounting, often due to environmental activity, the foundation bolt section of appearing is exposed in atmosphere, inevitably produces corrosion, the most by the sea, in the first-class complex environment in mountain, corrosion failure power is even more serious, as time went on, intensity own on foundation bolt and steadiness will cause the biggest impact, bring potential safety hazard to the equipment fixed.
Therefore, it is necessary to protective cap a kind of to foundation bolt design.
Summary of the invention
The purpose of this utility model is to provide a kind of novel anchor bolt protective cap, for the effective protection to foundation bolt.
This utility model adopts the following technical scheme that realization:
A kind of simple split type anchor bolt protective cap, including nut sleeve and the screw sleeve of protecting field foot bolt screw rod of protection anchor bolt nut；It is coated with epoxy resin layer between described nut sleeve bottom surface and foundation bolt base；Described nut sleeve top is threaded connection mode and installs screw sleeve, the external screw thread of described screw sleeve lower end and the screw-internal thread fit at nut sleeve top and between be coated with epoxy resin layer.
During use, nut sleeve is directly set in outside anchor bolt nut, nut sleeve will be located in the packing ring below anchor bolt nut simultaneously and includes in it, arranges epoxy resin layer and prevents air from entering, foundation bolt is caused corrosion oxidation between nut sleeve bottom surface and foundation bolt base.Screw sleeve is directly set on foundation bolt screw rod, in utilizing the female thread screwing into nut sleeve top of screw sleeve bottom, completes the protection to foundation bolt.
Preferably; in order to further make closely cooperating of screw sleeve and foundation bolt screw rod; the inwall of described screw sleeve is provided with the screw thread coordinated with foundation bolt screw rod; so screw sleeve is threadingly set in outside foundation bolt screw rod; and by, in the female thread screwing into nut sleeve top of screw sleeve bottom, completing the protection to foundation bolt.So, screw sleeve is more firm, increases the protected effect to foundation bolt.
This utility model also provides for the protective cap of another kind of version.
A kind of simple split type anchor bolt protective cap, including nut sleeve and the screw sleeve of protecting field foot bolt screw rod of protection anchor bolt nut；It is coated with epoxy resin layer between described nut sleeve bottom surface and foundation bolt base；Described screw sleeve is threaded connection mode and is installed on foundation bolt screw rod, and the bottom of described screw sleeve is coated with epoxy resin layer in the headspace of nut sleeve and between the bottom of screw sleeve and the headspace of nut sleeve.
During use, nut sleeve is directly set in outside anchor bolt nut, nut sleeve will be located in the pad below anchor bolt nut simultaneously and includes in it, arranges epoxy resin layer and prevent air from entering between nut sleeve bottom surface and foundation bolt base, prevents from foundation bolt is caused corrosion oxidation.Screw sleeve threadingly structure is set on foundation bolt screw rod; screw sleeve bottom is stretched in the headspace at nut sleeve top; arrange epoxy resin layer between prevents air from entering simultaneously, prevents from foundation bolt is caused corrosion oxidation, effectively protects foundation bolt.
This utility model has the advantage that
1, protective cap coordinates with foundation bolt closely, by epoxy resin layer, foundation bolt and moisture, air is effectively completely cut off, it is therefore prevented that the corrosion of foundation bolt, extends the service life of foundation bolt.
2, between nut sleeve and foundation bolt, bond with epoxy resin layer between screw sleeve and nut sleeve, play anti-theft function, it is to avoid the people destructively nut of the foot bolt section of spilling, pad and screw rod, for machinery, equipment and structure are played a protective role.
3, protective cap uses split type, it is possible to be applied on the foundation bolt of major part all size, applied range.
This utility model is reasonable in design, simple in construction, and nut sleeve and screw sleeve can use metal or organic plastics to make, it is possible to play a very good protection foundation bolt, reach to design requirement, have good marketing using value.
