Description
Technical Field
The utility model relates to a tunnel preliminary bracing's steel frame joint design especially relates to a buckle formula high-speed joint steel frame connects.
Background
At present, tunnels built in China and other large underground projects mostly adopt a mine method and a certain number of TBM methods, a large number of steel frames are adopted for supporting to ensure construction safety, the section shapes of the steel frames which can be manufactured are flexible, the steel frames also have certain adaptability to surrounding rock deformation, and the steel frames have great advantages, and particularly, the steel frames are adopted as primary supports for the tunnels built in poor strata such as soft rock large deformation zones and fault broken zones, so that the steel frames have great benefits. However, the existing steel frame joint adopts a bolt flange connection mode, as shown in fig. 1, screws and nuts need to be threaded, so that the following problems exist:
1. at present, most of the process is finished by manpower, and the process has the prominent difficulties of difficult manual steel frame positioning, scaffold needed in the tightening process and the like;
2. the consumed manpower and the consumed time are large, and the requirement of quick support is not met;
3. the steel arch structure mostly mainly takes small eccentric compression-bending as a main condition, so that the connecting joint has compression resistance and certain anti-dislocation capacity, and the existing angle steel-flange plate connecting form has poor economy.
Therefore, there is a need for a new snap-in quick connect steel frame joint that overcomes the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect, provide a buckle formula high-speed joint steel frame connects, mainly to adopting the steelframe as the tunnel and other underground works that just prop up, improved quick construction ability.
The utility model discloses a realize like this:
the utility model provides a buckle formula high-speed joint steelframe connects, including the first steel sheet and the second steel sheet that set up respectively, the joint is formed by first steel sheet and second steel sheet butt joint, all be equipped with on first steel sheet and the second steel sheet and tie head and draw-in groove, but the tie head of first steel sheet and the draw-in groove position of second steel sheet are corresponding and the joint cooperation, but the tie head of second steel sheet and the draw-in groove position of first steel sheet are corresponding and the joint cooperation.
Furthermore, the clamping groove is an L-shaped groove, and the bolt head is clamped after moving along a certain track in the L-shaped groove correspondingly matched with the bolt head.
Furthermore, a pre-dislocation amount is arranged between the bolt head and the L-shaped groove.
Further, an enlarged head is arranged on the outer side of the bolt head.
The utility model discloses following beneficial effect has:
1. the utility model discloses take steelframe quick-operation joint to connect with the form of hole chucking, buckle and draw-in groove have interlock, anticreep effect, connect the resistance to compression effectual, and anti dislocation rigidity is big, and has certain resistance to plucking ability, and it is strong to resist special loading ability.
2. The steel frame installation time is greatly shortened, the steel frame installation working strength is reduced, the steel frame can be quickly constructed in a severe and narrow tunnel working environment, the steel frame can be closed into a ring in time, the supporting resistance is provided, the stability of tunnel surrounding rock can be quickly improved, the construction safety is ensured, and good social benefits are achieved.
3. Due to the adoption of the buckle type joint, the using amount of the traditional joint angle steel can be properly reduced, the bolt is omitted, and the economic benefit is higher.
4. The utility model discloses only connecting to current steelframe and reforming transform, utilizing existing steelframe main part, can not increase too many materials, the cost is lower.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention (taking the grid steel frame as an example), and for those skilled in the art, other drawings (such as the steel frame) can be obtained according to the drawings without creative efforts.
