Description
Technical field
The utility model relates to a kind of steel column crab-bolt is installed, and specifically relates to a kind of adjustable crab-bolt of combination that steel column is installed that is applicable to.
Background technology
In steel column installation process, for improving installation strength and the firmness of steel column, can installation crab-bolt be set in steel column bottom, and existing installation crab-bolt is several reinforcing bars of simple welding under steel plate mostly, one of outer likeness in form little " stool ", structure is fixed, and after processing, shared volume is larger, inconvenience transportation, it is too simple that while crab-bolt also exists structure, intensity is less, and can not spacing, and poor accuracy is installed.When Steel for Large Steel Column is installed, crab-bolt can be low because of intensity, grab that ground ability poorly makes steel column that firmness is installed, safety reduces.
Utility model content
The purpose of this utility model be for existing steel column install crab-bolt structural strength low, grab the problems such as ground ability, inconvenience transportation, provide a kind of be convenient to transportation, installation capable of being combined, adjustable, grab the strong Steel for Large Steel Column installation crab-bolt of ability.
The technical scheme in the invention for solving the technical problem is:
A kind of adjustable crab-bolt of combination that is applicable to steel column installation, mainly comprise lower plate, upper plate and connecting screw rod, lower plate, upper plate, connecting screw rod are all set to the absolute construction of detachable and installation capable of being combined, are convenient to transportation and the assembling of crab-bolt, also reduced the welding assembly cost of crab-bolt.It is characterized in that: described lower plate and upper plate are all set to circular configuration, and be provided with shift holes on lower plate and upper plate, described lower plate thickness is greater than plate thickness, can improve crab-bolt intensity and grab ground ability, be applicable to the installation of Steel for Large Steel Column, both expand the scope of application of crab-bolt, and can increase again the firmness after steel column is installed.
The two ends of described connecting screw rod are separately positioned in the shift holes on lower plate and upper plate, and be provided with butt hook in the bottom of connecting screw rod, on the top of connecting screw rod, be provided with setscrew nut and bolt, connecting screw rod can be in shift holes adjusting position, meet the installation needs of different steel columns, can improve the degree of accuracy that steel column is installed.Described butt hook is arranged on the junction of connecting screw rod and lower plate, and described setscrew nut is arranged on the bottom of upper plate, by setscrew nut, can regulate the position of upper plate on connecting screw rod, can regulate steel column installation level and intensity.Described bolt is arranged on the top of upper plate, and the installation of being convenient to steel column is fixed.
Further, described shift holes is set to arcuate structure, and its quantity is 4-8.
Beneficial effect: the utility model lower plate, upper plate, connecting screw rod are set to independently syndeton, can combine installation in use, and is convenient to transportation.Arc shift holes is set in upper plate and lower plate, and convenient installation regulates, and can improve the degree of accuracy that steel column is installed.In connecting screw rod one end, be provided with butt hook, can improve the ground ability of grabbing of crab-bolt, thereby improve firmness and the safety that steel column is installed.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1. lower plate, 2. upper plate, 3. connecting screw rod, 4. shift holes, 5. butt hook, 6. setscrew nut, 7 bolts.
The specific embodiment
Below with reference to accompanying drawing, the utility model is described in detail.
As shown in accompanying drawing 1,2: a kind of adjustable crab-bolt of combination that is applicable to steel column installation, comprises lower plate 1, upper plate 2, connecting screw rod 3, shift holes 4, butt hook 5, setscrew nut 6, bolt 7.The utility model is all set to lower plate 1, upper plate 2, connecting screw rod 3 absolute construction of detachable and installation capable of being combined, is convenient to transportation and the assembling of crab-bolt, has also reduced the welding assembly cost of crab-bolt.It is characterized in that: described lower plate 1 is all set to circular configuration with upper plate 2, and be provided with shift holes 4 on lower plate 1 and upper plate 2, described lower plate 1 thickness is greater than upper plate 2 thickness, can improve crab-bolt intensity and grab ground ability, be applicable to the installation of Steel for Large Steel Column, both expanded the scope of application of crab-bolt, can increase again the firmness after steel column is installed, the two ends of described connecting screw rod 3 are separately positioned in the shift holes 4 on lower plate 1 and upper plate 2, and be provided with butt hook 5 in the bottom of connecting screw rod 3, on connecting screw rod 3 tops, be provided with setscrew nut 6 and bolt 7, connecting screw rod 3 can be at the interior adjusting position of shift holes 4, meet the installation needs of different steel columns, can improve the degree of accuracy that steel column is installed.Described butt hook 5 is arranged on the junction of connecting screw rod 3 and lower plate 1, and described setscrew nut 6 is arranged on the bottom of upper plate 2, by setscrew nut 6, can regulate the position of upper plate 2 on connecting screw rod 3, can regulate steel column installation level.Described bolt 7 is arranged on the top of upper plate 2, and the installation of being convenient to steel column is fixed.As preferably, described shift holes is set to arcuate structure, and its quantity is 6, is evenly distributed on lower plate 1, upper plate 2.The utility model can improve the degree of accuracy and the safety that Steel for Large Steel Column is installed.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
