Steel structure buildings are widely used in large public facilities, high-rise buildings, industrial plants, bridges and other fields.

[0030] In order to solve the problem that the connecting devices used in existing steel structure buildings may collide or rub with the connecting devices during the splicing process with the steel structural parts, thereby causing different degrees of wear on both sides, the present invention adopts a movable installation connection method, so that the connecting devices used in steel structure buildings are actively connected before being connected with the steel structural parts, providing a larger activity space for the splicing of the steel structure.
[0031] Embodiment 1: A fast assembled steel structure building connection device, such as Figure 1-Figure 8As shown, it includes an installation frame 10, and two bearing seats 11 distributed in left and right mirror images are fixedly connected to the middle and lower parts of the installation frame 10. A group of first sliding frames 12 are slidably connected to the left and right sides of the installation frame 10, each group includes two symmetrically distributed first sliding frames 12, and two adjacent first sliding frames 12 are located above the adjacent bearing seats 11. The middle part of the installation frame 10 is limitedly slidably connected to two T-shaped frames 13 distributed in left and right mirror images, and the two T-shaped frames 13 move laterally on the installation frame 10, and the T-shaped frames 13 are used to guide the lateral movement of the steel beam. The T-shaped frames 13 are located between the adjacent and mirror-distributed first sliding frames 12, and the installation frame 10 is limitedly slidably connected to two second sliding frames 14 distributed in left and right mirror images, and the two second sliding frames 14 move vertically on the installation frame 10, and the second sliding frames 14 are used to guide the vertical movement of the steel beam. The second sliding frame 14 is located between two adjacent and mirror-distributed first sliding frames 12, and the second sliding frame 14 is limited and slidably matched with the two adjacent and mirror-distributed first sliding frames 12. The second sliding frame 14 is located between the adjacent T-shaped frame 13 and the adjacent bearing seat 11, and the second sliding frame 14 is in contact and matched with the bearing seat 11. The facing sides of the mirror-distributed T-shaped frames 13 are fixedly connected with limiting plates 15 located in the installation frame 10, and the facing sides of the two mirror-distributed limiting plates 15 are in contact and matched with each other. When the facing sides of the two limiting plates 15 are fitted together, the two limiting plates 15 move together to the extreme position, and four limiting columns are fixedly connected to the left side of the right limiting plate 15, and the left limiting plate 15 is provided with four limiting grooves, and the limiting columns on the left limiting plate 15 are limited and slidably matched with the adjacent limiting grooves on the right limiting plate 15.
[0032] like Fig. 9 As shown, the distance between the middle of the installation frame 10 and the mirror distribution limit plate 15 is a, and the distance between the back side of the mirror distribution T-shaped frame 13 and the outer side of the installation frame 10 is b, which is used to make the opposite side of the mirror distribution limit plate 15 coincide with the cross section of the middle of the installation frame 10, and the back side of the mirror distribution T-shaped frame 13 coincide with the edge line of the outer side of the installation frame 10. When the edge line of the limit plate 15 coincides with the cross section of the middle of the installation frame 10, it proves that the lateral movement position of the steel beam has reached the required working position.
[0033] like Figure 5 , Figure 7 , Figure 8 and Fig.12As shown, the back sides of the two limit plates 15 distributed in left and right mirror images are fixedly connected with a fixed plate 20, and the fixed plate 20 is located below the adjacent second sliding frame 14. The back sides of the two fixed plates 20 distributed in left and right mirror images are fixedly connected with first elastic telescopic rods 21 distributed in a linear array. The telescopic parts of the three adjacent first elastic telescopic rods 21 distributed in a linear array are commonly fixedly connected with a limit pin 22, and the upper side of the limit pin 22 contacts and cooperates with the adjacent second sliding frame 14. The facing parts of the two second sliding frames 14 distributed in left and right mirror images are both provided with limit grooves, and the limit grooves on the second sliding frame 14 are limitedly cooperated with the adjacent limit pins 22. Through the cooperation of the first elastic telescopic rod 21, the adjacent limit pins 22 and the adjacent second sliding frame 14, the limit pins 22 provide vertical buffering for the adjacent second sliding frame 14, so as to avoid the steel beam from swinging randomly during splicing, resulting in a hard collision during the contact between the steel beam and the second sliding frame 14, and finally causing wear of the steel beam and the adjacent second sliding frame 14.
[0034] like Figure 7-Figure 9 As shown, a first L-shaped frame 30 is fixedly connected to the lower side of the right limiting plate 15, and a limiting shell 31 is fixedly connected to the lower side of the left limiting plate 15. The limiting shell 31 is limited and slidably matched with the first L-shaped frame 30. A second elastic telescopic rod 32 is fixedly connected to the lower side of the middle part of the left fixed plate 20. The telescopic portion of the second elastic telescopic rod 32 passes through the limiting shell 31 and slidably matched therewith. A limiting groove is arranged on the left side of the first L-shaped frame 30. The limiting groove on the left side of the first L-shaped frame 30 is limited and slidably matched with the telescopic portion of the second elastic telescopic rod 32. When the telescopic portion of the second elastic telescopic rod 32 is inserted into the limiting groove on the left side of the first L-shaped frame 30, the facing sides of the two limiting plates 15 are already fitted. A pad block 33 is limited and slidably connected in the limiting shell 31. The upper side of the pad block 33 is limited and matched with the second elastic telescopic rod 32, and the right side of the pad block 33 is in contact and matched with the first L-shaped frame 30.
[0035] like Figure 7 As shown, the back side of the mirror-distributed limit plate 15 is fixedly connected with a fixed seat 40, the fixed seat 40 on the right side is fixedly connected with a first slide bar 41, and the fixed seat 40 on the left side is limited and slidably matched with the first slide bar 41, and a spring sleeved on the outer periphery of the first slide bar 41 is arranged between the two fixed seats 40 distributed in the left and right mirror images, and the elastic force provided by the adjacent springs of the fixed seat 40 is used to achieve lateral buffering when the steel beam is spliced, so as to avoid the steel beam moving too fast during splicing, resulting in a hard collision between the steel beam and the adjacent T-frame 13 during the contact process, and finally causing wear of the steel beam and the adjacent T-frame 13.
[0036] When it is necessary to use this device to splice steel structural parts (taking the installation process of parts on the right T-shaped frame 13 as an example), the staff first installs the installation frame 10 and its attached parts on the steel column, and then the staff moves the steel beam to the top of the bearing seat 11 in the air, so that the steel beam is in contact with the upper side of the adjacent second sliding frame 14, and then the staff slowly moves the steel beam to the left, so that the steel beam squeezes the adjacent T-shaped frame 13. During the movement of the T-shaped frame 13, the limit plate 15 and the first L-shaped frame 30 are driven to move (the limit plate 15 moves the fixed plate 20, the limit pin 22 and its attached parts are moved synchronously). During the movement of the T-shaped frame 13 and the limit plate 15, the fixed seat 40 drives the first sliding rod 41 to squeeze the adjacent spring, so as to achieve lateral buffering when the steel beam is spliced, avoid the steel beam moving too fast during splicing, resulting in a hard collision between the steel beam and the adjacent T-shaped frame 13 during the contact process, and finally cause wear of the steel beam and the adjacent T-shaped frame 13.
[0037] During the process of splicing the steel beam, the steel beam contacts the adjacent second sliding frame 14. When the steel beam swings up and down, the steel beam squeezes the adjacent second sliding frame 14, so that the adjacent second sliding frame 14 squeezes the adjacent limit pin 22 downward. During the downward movement of the limit pin 22, the telescopic parts of its three adjacent first elastic telescopic rods 21 are squeezed, so that the first elastic telescopic rods 21 buffer the adjacent limit pins 22, so that the limit pins 22 provide vertical buffering for the adjacent second sliding frame 14, thereby preventing the steel beam from swinging randomly during splicing, resulting in a hard collision during the contact between the steel beam and the second sliding frame 14, and finally causing wear of the steel beam and the adjacent second sliding frame 14.
[0038] When the T-shaped frame 13 is squeezed by the steel beam until the edge line on the left side of the adjacent limiting plate 15 coincides with the cross-section of the middle part of the installation frame 10, the right side of the T-shaped frame 13 coincides with the edge line on the right side of the installation frame 10, proving that the lateral movement position of the steel beam has reached the required working position.
[0039] When the left side of the limit plate 15 coincides with the cross section of the middle of the mounting frame 10, the limit pin 22 has been inserted into the limit groove in the adjacent second sliding frame 14, thereby limiting the lateral position of the T-shaped frame 13. The staff then presses the steel beam downward to drive the adjacent second sliding frame 14 to move downward until it is in contact with the adjacent bearing seat 11. At this time, the support of the adjacent second sliding frame 14 by the bearing seat 11 enhances the support effect on the steel beam.
[0040] After completing the adjustment of the horizontal and vertical positions of the steel beam, the staff pushes the two first sliding frames 12 on the right side to the adjacent sides, so that the two first sliding frames 12 on the right side move toward each other and fit with the front and rear sides of the steel beam respectively.
[0041] After the two first sliding frames 12 on the right side are respectively fitted with the front and rear sides of the steel beam, the staff uses bolts to fix the steel beam between the two first sliding frames 12 on the right side, thereby completing the splicing of the right steel beam.
[0042] When the splicing of the right steel beam is completed, the staff moves the new steel beam to the left side of the installation frame 10. During the movement of the steel beam to the right, the T-shaped frame 13 on the left is squeezed, so that the T-shaped frame 13 on the left drives the adjacent limiting plate 15 to move to the right. During the movement of the limiting plate 15 on the left, the limiting shell 31 is driven to move to the right, so that the limiting shell 31 is gradually sleeved on the outer side of the first L-shaped frame 30. When the limiting shell 31 moves to the right side until the left side of the first L-shaped frame 30 is in contact with the right side of the cushion block 33, the limiting plate 15 continues to move to the right side. When the squeezing force of the first L-shaped frame 30 on the cushion block 33 exceeds the squeezing force applied by the telescopic part of the second elastic telescopic rod 32 to the cushion block 33, the cushion block 33 moves to the left synchronously with the first L-shaped frame 30, so that the squeezing force of the telescopic part of the second elastic telescopic rod 32 is applied to the first L-shaped frame 30.
[0043] When the edge line on the right side of the left limiting plate 15 coincides with the cross section in the middle of the mounting frame 10, the telescopic portion of the second elastic telescopic rod 32 has been inserted into the limiting groove on the left side of the first L-shaped frame 30, and several limiting columns on the right limiting plate 15 have been inserted into the adjacent limiting grooves on the left limiting plate 15. At this time, the limiting of the two limiting plates 15, the two T-shaped frames 13 and the accessory parts is completed. Therefore, the splicing of the steel beams and steel columns is completed through the above-mentioned parts.
[0044] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 and Figure 6 As shown, two groups of second sliding bars 50 are also included, and the two groups of second sliding bars 50 are both slidably connected to the installation frame 10, and each group of second sliding bars 50 is symmetrically distributed. A tension spring is arranged between the first sliding frame 12 and the installation frame 10. This tension spring is used to drive the adjacent first sliding frame 12 to move. When the steel beam is not assembled, the second sliding frame 14 is located between the two adjacent first sliding frames 12, so that the adjacent tension springs on the two adjacent first sliding frames 12 are in a stretched state, and the second sliding bar 50 is fixedly connected to the adjacent first sliding frame 12, and a fixing block 51 is fixedly connected to one end of the second sliding bar 50 away from the adjacent first sliding frame 12, and the fixing blocks 51 on each group of first sliding frames 12 are centrally symmetrically distributed. After the second sliding frame 14 moves downward until it is no longer in contact with the two adjacent first sliding frames 12, the first sliding frame 12 moves toward the middle of the installation frame 10 under the action of the adjacent tension springs to realize automatic clamping of the steel beam.
[0045] like Figure 1-Figure 5 , Figure 7 , Figure 10-12As shown, the facing parts of the two second sliding frames 14 distributed in left and right mirror images are fixedly connected with the two second L-shaped frames 60 distributed in front and back mirror images, and the facing sides of the upper parts of the two second L-shaped frames 60 adjacent to each other and distributed in front and back mirror images are fixedly connected with tilting blocks 61. The middle and upper part of the installation frame 10 is limitedly slidably connected with the two third sliding frames 62 distributed in left and right mirror images, and the facing parts of the two third sliding frames 62 distributed in left and right mirror images are fixedly connected with the fixing pins 63 distributed in mirror images. The tilting blocks 61 are pressed and matched with the adjacent fixing pins 63. When the tilting blocks 61 press the adjacent fixing pins 63, the fixing pins 63 drive the adjacent third sliding frames 62 to move to the side away from the installation frame 10. The third sliding frames 62 are provided with sliding parts 64 distributed in mirror images, and the installation frame 10 is provided with two groups of sliding grooves 65. Each group of sliding grooves 65 is symmetrically distributed, and the sliding grooves 65 are slidably matched with the adjacent sliding parts 64.
[0046] like Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 10-12 As shown, the mounting frame 10 is slidably connected with two counterweight blocks 70 distributed in left and right mirror images, and the counterweight blocks 70 are slidably matched with adjacent sliding grooves 65. The lower sides of the two counterweight blocks 70 distributed in left and right mirror images are respectively squeezed and matched with adjacent third sliding frames 62. The counterweight blocks 70 are used to squeeze the adjacent third sliding frames 62. The two counterweight blocks 70 distributed in left and right mirror images are both embedded with the mounting frame 10, so that after the counterweight blocks 70 are inserted into the mounting frame 10, the edge lines on the upper sides of the counterweight blocks 70 can coincide with the edge lines on the upper sides of the mounting frame 10. The lower sides of the two third sliding frames 62 distributed in left and right mirror images are fixedly connected to the limiting frame 80, and the mirror image distributed T-shaped frames 13 are respectively provided with limit grooves that limit the adjacent limit frames 80. During the downward movement of the limit frame 80, it is gradually inserted into the limit grooves on the adjacent T-shaped frame 13, thereby enhancing the stability of the third sliding frame 62 structure.
[0047] When the steel beam is spliced to the mounting frame 10, the steel beam gradually releases the limit on the two adjacent first sliding frames 12 during the process of squeezing the adjacent second sliding frames 14 downwards to fit with the adjacent bearing seats 11; after the second sliding frames 14 fit with the adjacent bearing seats 11, the two adjacent first sliding frames 12 move toward each other under the action of adjacent tension springs (the movement of the first sliding frames drives the adjacent second sliding rods 50 and fixed blocks 51 to move as well), and gradually fit with the front and rear sides of the steel beam to achieve automatic splicing of the two adjacent first sliding frames 12.
[0048] As the second sliding frame 14 moves downward along with the steel beam, it drives the two adjacent second L-shaped frames 60 to move downward synchronously. The two adjacent second L-shaped frames 60 respectively drive the adjacent tilting blocks 61 to move downward. When the tilting blocks 61 move downward, they squeeze the adjacent fixing pins 63, so that the adjacent fixing pins 63 drive the adjacent third sliding frame 62 and the adjacent two sliding parts 64 to move in a direction away from the adjacent second L-shaped frames 60, and make the adjacent two sliding parts 64 contact with the adjacent two sliding grooves 65 respectively.
[0049] After the two adjacent sliding parts 64 contact the two adjacent sliding grooves 65 respectively, under the action of the gravity of the adjacent counterweight block 70, the counterweight block 70 drives the adjacent third sliding frame 62 to slide downward (in the process of the third sliding frame 62 sliding downward, the two adjacent sliding parts 64 slide downward along the two adjacent sliding grooves 65 respectively), and the third sliding frame 62 drives the adjacent limiting frame 80 to move downward synchronously. In the process of moving downward, the limiting frame 80 gradually inserts into the limiting groove on the adjacent T-shaped frame 13 (to achieve the effect of strengthening the structural stability of the third sliding frame 62). In the process of moving downward, the third sliding frame 62 contacts the upper side of the steel beam and squeezes it downward.
[0050] When the lower side of the third sliding frame 62 is in contact with the upper side of the steel beam, the fixation of the steel beam is completed. Then the staff connects all the bearing seats 11 and all the second sliding frames 14 to the lower side of the steel beam through bolts, and then connects all the first sliding frames 12 to the front and rear sides of the steel beam through bolts, and finally connects all the third sliding frames 62 to the upper side of the steel beam through bolts.

The present invention is subject to various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the protection claimed.
