Abstract
The utility model relates to an anchor bolt, which comprises N bolt unit components and M thread casing components, wherein N is odd; each bolt unit component is a stud; M is even; and one thread casing component is sleeved between every two bolt unit components. The anchor bolt has the beneficial effects that due to processing in segments and breaking up the whole into parts, the processing is simplified, the cost is reduced, the anchor bolt is convenient to transport, the performance of the anchor bolt is ensured, and the use effect is not affected.
Description
Technical field
The utility model relates to being connected of a kind of high-rise building and underground foundation, relates in particular to a kind of anchor bolt.
Background technology
Because the forceful action of earthquake, wind load and other shock wave, the superstructure of super highrise building, particularly roof parts are easy to produce roll and pitch, frequent shake, even excessive deformation, inclination appear.The consequence that these powerful external force produce, all the stability and security to super high rise building constitutes a latent danger, even causes serious security incident.
In order to reduce this class hidden danger, eliminate potential threat, between the ground and underground structure of modern super high rise building, all adopt mechanical firm joint device, improve on the ground bonding strength with underground structure, assurance is controlled at dangerous factors such as the runout of top of building, shake, inclination in the scope of design permission.
The affixed mode of building up-down structure has multiple, and wherein the most frequently used is (high-strength prestress) anchor bolt and composite set.The anchor bolt outward appearance of this device is like an especially big stud, and diameter can be as big as 100mm, and length reaches 10m, and material mostly is high-quality alloy steel, and through appropriate heat treatment, guarantees its high-intensity performance and fully long application life.
In the engineering practice, anchor bolt (being called for short " crab-bolt ") hypomere and anchoring annex are buried in underground foundation, to guarantee affixed intensity, keep the stability of building.In order to strengthen affixed intensity, treat that the basis is dry after, crab-bolt is applied prestressing force (its value is greater than the real work tensile stress), no longer produce distortion (elongation) when making crab-bolt work, assurance crab-bolt and foundation structure become a flawless integral body.
Crab-bolt is born huge pulling force, and cross section diameter can be not little; The crab-bolt hypomere is buried underground, and length can not lacked.So a not only thick but also long crab-bolt processing just becomes a difficult problem: equipment such as blanking, forging and pressing, cutting, heat treatment, detection must be oversized, and increase man-hour, the difficulty of processing height, thereby cost improves.And general factory can't process.
Be worth mentioning especially: the crab-bolt large usage quantity.According to statistics, the crab-bolt consumption of an engineering, hundreds of at least, thousands of at most, super large engineering even up to ten thousand.The total cost of crab-bolt consumption has become an important problem.
Monolithic (high-strength prestress) crab-bolt commonly used is the problem that the technician will solve as how multistage releasable connection bolt replaces.
Summary of the invention
The utility model technical issues that need to address have provided a kind of anchor bolt, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: N bolt unit assembly; Described N is an odd number; Described each bolt unit assembly is a stud; Also comprise: M threaded sleeve assembly; Described M is an even number; Threaded sleeve assembly of socket between described per 2 bolt unit assemblies.
Compared with prior art, the beneficial effects of the utility model are: owing to segmental machining, break the whole up into parts, thereby simplify processing, reduce cost, convenient transportation, and guaranteed performance do not influence result of use.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: N bolt unit assembly 1; Described N is an odd number; Described each bolt unit assembly is a stud; Also comprise: M threaded sleeve assembly 2; Described M is an even number; Threaded sleeve assembly 2 of socket between described per 2 bolt unit assemblies 1.
The crab-bolt segmental machining reduces the crab-bolt difficulty of processing, and equipment is popular, and reduce man-hour, and cost descends, a large amount of uses of favourable crab-bolt, and general factory can both produce in batches with low cost.
Claims (1)
1. an anchor bolt is characterized in that comprising: N bolt unit assembly; Described N is an odd number; Described each bolt unit assembly is a stud; Also comprise: M threaded sleeve assembly; Described M is an even number; Threaded sleeve assembly of socket between described per 2 bolt unit assemblies.
