Detailed Description

The present application is described in further detail below in conjunction with figures 1-7.

The embodiment of the application discloses a temporary connection structure of steel column. Referring to fig. 1 and 2, the temporary connection structure of the steel column 1 includes an ear plate 2 adjacent to the ends of two sections of the steel column 1, connection clamping plates 3 disposed at both sides of the ear plate 2, and a fixing rod 4 connecting the two connection clamping plates 3.

Referring to fig. 3, when the steel column 1 is lifted in place, after the steel column 1 coincides with the center line of the next section of steel column 1, the worker adjusts the temporary connecting clamping plate 3 and wears the mounting bolts 12, thereby temporarily fixing the positions of the upper and lower sections of steel columns 1, and preparing for subsequent measurement correction and welding.

The dead lever 4 links into a whole with two solitary connecting splint 3, when dead lever 4 and otic placode 2 looks butt for otic placode 2, connecting splint 3's through-hole is on same horizontal plane, in order to reduce the handheld connecting splint 3 of staff and otic placode 2 to the construction step in hole.

Referring to fig. 2 and 3, for convenience of description, the lug plate 2 of the upper section of steel column 1 is defined as a first lug plate 21, and the lug plate 2 of the lower section of steel column 1 is defined as a second lug plate 22.

Specifically, the ear plate 2 is provided with a plurality of first through holes 6, and the connecting clamping plate 3 is provided with a plurality of second through holes 7 corresponding to the first through holes 6 one by one. After the first through hole 6 and the second through hole 7 are aligned, the bolt 12 is sequentially worn on the second through hole 7, the first through hole 6 and the second through hole 7 and then fixedly connected with the first through hole and the second through hole 7, so that the positions of the upper steel column 1 and the lower steel column 1 are temporarily fixed.

In this embodiment, the first ear plate 21 and the second ear plate 22 are both provided with three first through holes 6, and the connecting plate is provided with six second through holes 7.

And, the upper end of connecting splint 3 has seted up the third through-hole 8 that supplies dead lever 4 to wear to establish, and third through-hole 8 sets up in second through-hole 7 top. And the two ends of the fixed rod 4 are also provided with limiting pieces 5 for limiting the connecting clamping plate 3 from sliding off the end part of the fixed rod 4.

In this embodiment, the limiting member 5 is integrally formed with the connecting rod. In the mill of preparation steel column 1, after the staff wears the dead lever 4 and establishes two connecting splint 3, utilize modes such as punching press, welding to set up locating part 5, the diameter of locating part 5 is greater than the diameter of third through-hole 8 to the landing of limiting connecting splint 3.

In other embodiments, the limiting member 5 may also be a nut, and the two ends of the fixing rod 4 are correspondingly provided with threads matched with the nut. The staff can assemble the fixed rod 4 and the connecting clamping plate 3 on the ground and then take the work to the high altitude.

The implementation principle of the temporary connection structure of the steel column in the embodiment of the application is as follows:

the staff slides the connecting clamping plate 3 to the two ends of the fixed rod 4, and the fixed rod 4 is placed on the upper edge of the first clamping plate; the worker then moves the connecting clamping plates 3 on both sides of the ear plate 2 toward the middle so that the connecting clamping plates 3 and the ear plate 2 approach each other.

At this time, the first through hole 6 of the ear plate 2 and the second through hole 7 of the connecting clamping plate 3 are on the same horizontal plane, so that the step that the connecting clamping plate 3 and the ear plate 2 are opposite to each other by the hand of a worker is reduced, the construction process is simplified, and the installation efficiency of the worker is improved.

After that, the worker moves along the length direction of the first ear plate 21 so that the first through holes 6 are in one-to-one correspondence with the second through holes 7. The worker installs the two bolts 12 at the uppermost and the lowermost, further fixes the positional relationship between the connecting clamp plate 3 and the ear plate 2, installs the bolts 12 with other through holes, tightens all nuts 13, and temporarily fixes the upper and lower sections of steel columns 1.

In this embodiment, this steel column 1 temporary connection mechanism simple structure has advantages such as simplified staff's installation step, optimized staff's installation environment simultaneously, improves staff's installation effectiveness.

Example 2:

example 2 was further set up on the basis of example 1.

In this embodiment, the fixing rod 4 is primarily fixed to the first ear plate 21 by means of a clamping connection. When the fixing rod 4 is abutted against the first lug plate 21, the first through holes 6 and the second through holes 7 are in one-to-one correspondence. The construction steps that workers need to locate holes for the second time are reduced.

Referring to fig. 4, specifically, the upper end of the first ear plate 21 starts to have a first groove 9 matching with the shape of the fixing rod 4, and when the bottom of the fixing rod 4 abuts against the bottom of the first groove 9, the first through holes 6 are in one-to-one correspondence with the second through holes 7.

the staff places the fixed rod 4 of the connection structure at the upper edge of the first ear plate 21, and then the staff moves the fixed rod 4 so that the fixed rod 4 falls into the first groove 9, thereby reducing the step of secondary hole alignment of the staff. The staff then moves the connecting clamping plates 3 at the two sides of the ear plate 2 to the middle, thereby preliminarily fixing the relative position between the connecting structure and the ear plate 2. At this time, the second through holes 7 of the connecting clamping plate 3 and the first through holes 6 of the ear plate 2 are in one-to-one correspondence.

Referring to fig. 5, in other embodiments, a second groove 10 that is matched with the upper ear plate 2 may be formed in the middle of the fixing rod 4, so that when the bottom of the second groove 10 abuts against the first ear plate 21, the first through holes 6 and the second through holes 7 are in one-to-one correspondence.

Example 3:

example 3 was further set up on the basis of example 2.

In the present embodiment, the non-slip sheet 11 is provided between the fixing lever 4 and the first ear plate 21. The antiskid sheet 11 restricts the relative sliding between the fixing rod 4 and the first ear plate 21, and improves the stability of the preliminary fixation of the connecting structure with the first ear plate 21.

The situation that the fixing rod 4 inclines and moves and the secondary adjustment of the staff is needed due to the fact that the distances from the connecting clamping plates 3 on the two sides of the first groove 9 to the center of the lug plate 2 are different is reduced.

Referring to fig. 6, specifically, the non-slip sheet 11 is disposed at the bottom of the first groove 9, and the area of the non-slip sheet 11 is smaller than the bottom area of the first groove 9, thereby reducing the influence of the non-slip sheet 11 on the connection clamping plate 3.

In other embodiments, referring to fig. 7, the non-slip sheet 11 may be disposed at the bottom of the second groove 10.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
