Description

Construction method for connecting steel beams

Technical Field

The invention relates to the field of steel structure construction, in particular to a construction method for steel beam connection.

Background

In the steel structure building construction, referring to fig. 1, adjacent steel columns 100 are connected by using a first steel beam 110, and in the production process of the steel columns 100, a first steel beam 110 with a certain length is generally extended from a preset height, then the steel columns are transported to a construction site and the steel columns 100 are fixed, the first steel beam 110 extended from the adjacent steel columns is connected by using a second steel beam 200, so that the adjacent steel columns 100 are connected, and after the second steel beam 200 is connected with the first steel beam 110, the rigidity is poor, so that H-shaped double-plywood needs to be fixed on the second steel beam 200 and the web 111 of the first steel beam 110 at the same time, so as to reinforce the connection between the second steel beam 200 and the steel columns 100.

In the related art, referring to fig. 1, four clamping plates are arranged on the h-shaped double clamping plate, and are divided into a first clamping plate 210, a second clamping plate 220, a third clamping plate 230 and a fourth clamping plate 240, and the four clamping plates are all fixed on the second steel beam 200, wherein: the first clamping plate 210 and the second clamping plate 220 are oppositely arranged, the third clamping plate 230 and the fourth clamping plate 240 are oppositely arranged, the first clamping plate 210 and the fourth clamping plate 240 are arranged at intervals, and the second clamping plate 220 and the third clamping plate 230 are arranged at intervals. The final purpose is as follows: the second and third clamping plates 220 and 230 are fixed to one side of the web 111, and the first and fourth clamping plates 210 and 240 are fixed to the other side of the web 111, thereby achieving the connection of the reinforced steel beam and the steel column. Because the distance between the webs 111 on the preset first steel beam 110 on the adjacent steel columns 100 is less than the length of the second clamping plate 220 and the third clamping plate 230 which are arranged at intervals, when the H-shaped double clamping plates are hoisted to be in butt joint with the preset steel beams, the following difficulties exist: when the H-shaped double clamp plates are directly hoisted, the second clamp plate 220 and the third clamp plate 230 cannot cross the web 111 to realize that the second clamp plate 220 and the third clamp plate 230 are arranged on the side of the web 111 away from the first clamp plate 210 and the fourth clamp plate 240. Therefore, in the field construction, the clamping plate to be installed on one side of the web 111 is hoisted, then the clamping plate to be installed on the other side of the web 111 is hoisted, and then the clamping plate and the web 111 are spliced. So will consume great man-hour on the hoist and mount to the splint, lead to the construction cycle overlength of steel construction, and because the hoist and mount process to each splint is more, reduced the high altitude construction security of steel construction.

The construction method of steel beam connection is used for connecting adjacent steel columns 100, a first steel beam 110 is arranged at a preset height of each steel column 100, the first steel beams 110 of the adjacent steel columns 100 are oppositely arranged, and a gap 300 exists between the first steel beams 110.

In some embodiments, referring to fig. 2, 4 and 5, a construction method of steel beam connection includes:

s1, preparing a first clamping plate 210, a second clamping plate 220, a third clamping plate 230, a fourth clamping plate 240 and a second steel beam 200.

S2, fixing the first clamping plate 210 and the fourth clamping plate 240 on one side surface of the second web 201, so that part of the first clamping plate 210 and the second web 201 are laminated, and part of the fourth clamping plate 240 and the second web 201 are laminated; the second clip 220 and the third clip 230 are rotatably connected to the other side surface of the second web 201, respectively, and the second clip 220 and the third clip 230 are stacked on each other in a closed state. The process is to fix the first, second, third and fourth clamping plates 210, 220, 230 and 240 to the second steel beam 200 and to make the second and third clamping plates 220 and 230 in a closed state.

S3, lifting the second steel beam 200, and enabling the second clamping plate 220 and the third clamping plate 230 to penetrate through the gap 300.

And S4, stacking and fixing the part of the first clamping plates 210 lifted to the preset height on one side surface of one first web plate 111, and stacking and fixing the part of the fourth clamping plates 240 lifted to the preset height on one side surface of the other first web plate 111. The process is to fix the first clip 210 and the fourth clip 240 to the first web 111.

S5, rotating the second clamping plate 220 and the third clamping plate 230 to open the second clamping plate 220 and the third clamping plate 230 to be in an unfolded state; a third clip 230 is attached and secured to the first and second webs 111, 201 and a fourth clip 240 is attached and secured to the other of the first and second webs 111, 201. The process is to spread the second and third jaws 220 and 230 apart so that they can be smoothly mounted on the second and corresponding first webs 201 and 111.

Along the width direction of the second web 201, since each clamping plate protrudes relative to the second web 201, and the protruding portion needs to be installed on the first web 111, in this direction, the overall length of the first clamping plate 210 and the fourth clamping plate 240 (i.e. the distance between the side of the first clamping plate 210 facing away from the fourth clamping plate 240 and the side of the fourth clamping plate 240 facing away from the first clamping plate 210), and the overall length of the second clamping plate 220 and the third clamping plate 230 (i.e. the distance between the side of the second clamping plate 220 facing away from the third clamping plate 230 and the side of the third clamping plate 230 facing away from the second clamping plate 220) are both greater than the distance between the two first steel beams 110. The second and third jaws 220 and 230 in the unfolded state cannot pass from one side of the first web 111 to the other side of the first web 111.

In the embodiment of the present invention, the second clamping plate 220 and the third clamping plate 230 in the closed state pass through the gap 300 from one side of the first steel beam 110 to the other side, and then the closed state is changed to the unfolded state, so that the first clamping plate 210, one of the first webs 111 and the second clamping plate 220 are sequentially stacked, and the fourth clamping plate 240, the other of the first webs 111 and the third clamping plate 230 are sequentially stacked, that is, in the process of installing the second steel beam 200 and each clamping plate between adjacent first steel beams 110, the four clamping plates can be simultaneously hoisted and smoothly installed between adjacent first steel beams 110 at one time, and the construction period of the steel structure is shortened; and the hoisting of the four clamping plates and the second steel beam 200 is completed at one time, so that the construction safety of the steel structure is improved.

In some embodiments, referring to fig. 7, S1 comprises: a plurality of rotation members 400 and a plurality of ring structures 500 are prepared. S2 comprises the following steps: fixing one of the rotating member 400 or the annular structure 500 to the second clamping plate 220 and the other one to the second web 201, and inserting the rotating member 400 into the annular structure 500; one of the rotating member 400 or the ring structure 500 is fixed to the third clamping plate 230, and the other is fixed to the second web 201, and the rotating member 400 is inserted into the ring structure 500.

The second clamping plate 220 and the third clamping plate 230 can be rotatably connected to the second steel beam 200 by inserting the rotating member 400 into the annular structure 500, so that the operation is simple and the use is convenient.

Specifically, referring to fig. 8, the rotating member 400 is L-shaped, and is divided into a first column 410 and a second column 420, the annular structure 500 is annular and has a through hole 510 penetrating along the axial direction, and the first column 410 is inserted through the through hole 510 and can rotate along the axial direction of the annular structure 500; in this embodiment, the ring structure 500 is welded to the second web 201, the second column 420 of the partial rotation member 400 inserted into the corresponding ring structure 500 is welded to the second clamping plate 220, and the second column 420 of the partial rotation member 400 inserted into the corresponding ring structure 500 is welded to the third clamping plate 230.

In other embodiments, referring to fig. 9, the partial ring structure 500 may be welded and fixed to the edge of the second clamping plate 220, the partial ring structure 500 may be welded and fixed to the edge of the third clamping plate 230, and in each rotating member 400, the first column 410 penetrates through the corresponding ring structure 500, and the second column 420 is welded and fixed to the second web 201. This arrangement also enables the second and third clamping plates 220, 230 to be pivotally connected to the second steel beam 200.

It is understood that, in the above two embodiments, besides the fixing manner of welding the rotating member 400 and the annular structure 500 to the corresponding second clamping plate 220, third clamping plate 230 and second web 201, other fixing manners, such as screw fixing, may be adopted, so as to fix the rotating member 400 and the annular structure 500, which is not described herein too much.

In some embodiments, referring to fig. 1, the construction method of steel beam connection further includes a step S6 provided after the step S5, and the step S6 includes: the rotor 400 and the ring structure 500 are removed.

The removed rotating member 400 and the ring structure 500 can be reused, avoiding waste; on the other hand, the second steel beam 200 can be more beautiful as a whole by detaching the two from the second steel beam 200.

In some embodiments, the S3 step further comprises: the first clamping plate 210 and the fourth clamping plate 240 are placed at one side of the second steel beam 200, and then the second steel beam 200 is lifted. The step S4 further comprises the following steps: after the second steel beam 200 is lifted to a predetermined height, the second steel beam 200 is moved toward the first web 111 such that a portion of the first clamping plate 210 and a portion of the fourth clamping plate 240 are stacked on the corresponding first web 111.

Along the width direction of the second web 201, since the overall length of the first clamping plate 210 and the fourth clamping plate 240 and the overall length of the second clamping plate 220 and the third clamping plate 230 are greater than the distance between the two first steel beams 110, the second steel beam 200 cannot be directly lifted below the first steel beam 110, and therefore, the second steel beam 200 needs to be lifted to the side of the first steel beam 110, the second steel beam 200 is moved toward the first steel beam 110, and the first clamping plate 210 and the fourth clamping plate 240 of the protruding portion are stacked on the corresponding first web 111.

It can be understood that, since the second clamping plate 220 and the third clamping plate 230 are in the closed state, the second clamping plate 220 and the third clamping plate 230 can smoothly pass through the gap 300 during the process that the second steel beam 200 moves towards the first steel beam 110 at one side of the first steel beam 110.

In some embodiments, referring to fig. 6-7, S4 includes a lifting and positioning step, where the lifting and positioning step is: aligning the mounting holes 600 on the first clamping plate 210 and the first web 111 and the mounting holes 600 on the fourth clamping plate 240 and the first web 111, fixing the first clamping plate 210 and the first web 111 by spot welding, and fixing the fourth clamping plate 240 and the first web 111 by spot welding.

By corresponding the first clamping plate 210 to the corresponding mounting hole 600 on the first web 111, the position determination of the first clamping plate 210 and the first steel beam 110 can be realized, so as to realize the height calibration of the first steel beam 110 and the second steel beam 200; by corresponding the fourth clamping plate 240 to the corresponding mounting hole 600 on the first web 111, the position of the fourth clamping plate 240 and the first steel beam 110 can be determined, so as to calibrate the height of the first steel beam 110 and the second steel beam 200.

In some embodiments, referring to fig. 10, S3 comprises: the second steel beam 200 is lifted to a predetermined height, and the second flange 202 is butted against the first flange 112. In this embodiment, the flanges of the second steel beam 200 lifted to the two opposite sides of the second steel beam 200 are respectively butted with the flanges of the first steel beam 110, so that the height calibration of the second steel beam 200 and the first steel beam 110 can be realized. Specifically, after second flange 202 and first flange 112 are butted, they are welded and fixed at the butted points.

It is understood that the welding step after the second flange 202 and the first flange 112 are butted and butted against the butt joint may be performed before the second clamping plate 220 and the third clamping plate 230 are fixed to the first steel beam 110, or after the second clamping plate 220 and the third clamping plate 230 are fixed to the first steel beam 110, which may be selected according to actual needs.

Two different methods are shown in the above two embodiments to calibrate the height of the second steel beam 200 and the first steel beam 110. That is, the height of the second steel beam 200 and the first steel beam 110 may be calibrated in S3 (i.e., the present embodiment) or in S4 (i.e., the previous embodiment), and may be specifically selected according to actual needs.

In some embodiments, referring to fig. 3, S2 comprises: after the first clamping plate 210 and the fourth clamping plate 240 are attached to the second web 201, the first bolt 700 is inserted into the first clamping plate 210 and the second web 201 and fixed by spot welding, and the first bolt 700 is inserted into the fourth clamping plate 240 and the second web 201 and fixed by spot welding.

It can be understood that when the first clamping plates 210 and the fourth clamping plates 240 are fixed by using the first bolts 700, the following difficulties are caused if the first clamping plates 210 and the second web 201, and the fourth clamping plates 240 and the second web 201 are locked by nuts: during the process of changing the second clamping plate 220 and the third clamping plate 230 from the closed state to the unfolded state, the second clamping plate 220 and the third clamping plate 230 cannot be directly mounted on the second web 201 because nuts exist between the second clamping plate 220 and the second web 201 and between the third clamping plate 230 and the second web 201.

Therefore, in the present embodiment, the first bolt 700 is inserted through the first clamping plate 210 and the second web 201 and fixed by the spot welding method, and the first bolt 700 is inserted through the fourth clamping plate 240 and the second web 201 and fixed by the spot welding method, so that the first clamping plate 210 and the second steel beam 200, and the fourth clamping plate 240 and the second steel beam 200 can be temporarily fixed before the second clamping plate 220 and the third clamping plate 230 are in the unfolded state, and the first bolt 700 can be directly inserted through the mounting hole 600 of the corresponding second clamping plate 220 and third clamping plate 230 in the subsequent process of changing the closed state of the second clamping plate 220 and the third clamping plate 230 into the unfolded state.

In some embodiments, S5 comprises: in the process of changing the closed state of the second splint 220 and the third splint 230 into the unfolded state, after the first bolt 700 at the corresponding position is inserted into the third splint 230 and the second splint 220, the second splint 220 and the third splint 230 are in the unfolded state; the first clamping plate 210, the second clamping plate 220, the third clamping plate 230, and the fourth clamping plate 240 are fixed to the second steel beam 200 by tightening the first bolt 700 (e.g., using nuts).

In the embodiment, after the second steel beam 200 is lifted to a preset height, the first bolts 700 pre-arranged on the first clamping plates 210 and the second web plate 201, the fourth clamping plates 240 and the second web plate 201 are correspondingly arranged on the mounting holes 600 arranged on the second clamping plates 220 and the third clamping plates 230, so that the first clamping plates and the second web plate 201 are stacked.

In some embodiments, referring to fig. 5, the S4 step includes: after the first clamping plate 210 and the fourth clamping plate 240 are stacked on the first web 111, the second bolt 800 is inserted into the first clamping plate 210 and the first web 111, and the fourth clamping plate 240 and the first web 111, and the second bolt 800 is temporarily fixed (for example, spot-welded). S5 comprises the following steps: after the second clamping plate 220 and the third clamping plate 230 are respectively attached to the two first webs 111, the second bolt 800 is inserted through the second clamping plate 220 and the first webs 111, and the third clamping plate 230 and the first webs 111, and the second bolt 800 is locked. In brief, the present embodiment fixes the first clamping plate 210, the second clamping plate 220, the third clamping plate 230, and the fourth clamping plate 240 to the corresponding first steel beam 110 using the second bolt 800.

In this embodiment, in the step S4, the second bolt 800 is temporarily fixed on the first clamping plate 210 and the first steel beam 110, the fourth clamping plate 240 and the first steel beam 110, and in order to facilitate the process of subsequently changing the closed state of the second clamping plate 220 and the third clamping plate 230 into the unfolded state, the second bolt 800 can smoothly penetrate through the mounting hole 600 of the corresponding second clamping plate 220 and third clamping plate 230; in the present embodiment, in step S5, the second bolts 800 temporarily fixed on the first clamping plate 210 and the first steel beam 110, the fourth clamping plate 240 and the first steel beam 110 are correspondingly inserted into the mounting holes 600 of the second clamping plate 220 and the mounting holes 600 of the third clamping plate 230, so that the first clamping plate 210 and the second clamping plate 220 are stacked and fixed on the corresponding first web 111, and the third clamping plate 230 and the fourth clamping plate 240 are stacked and fixed on the corresponding first web 111.

The second clamping plate 220 and the third clamping plate 230 in the closed state are temporarily fixed, so that the second steel beam 200 can be lifted up, the second clamping plate 220 and the third clamping plate 230 are prevented from shaking, and meanwhile, the second clamping plate 220 and the third clamping plate 230 can smoothly pass through the gap 300 in the S3 process.

Specifically, the second clamping plate 220 and the third clamping plate 230 are bolted in this embodiment, so that the bolts can be conveniently detached when the second clamping plate 220 and the third clamping plate 230 need to be unfolded later.
