[0002] During the construction of steel structures, especially portal steel frames, multiple sections of steel beams need to be assembled on the ground before being hoisted. Since the steel beams of a single steel frame are multi-fold line-shaped as a whole, and the slopes of the fold line nodes are different, it is necessary to customize a special tire frame for the splicing of the angle nodes of the multi-fold line steel beams, which has high construction costs and poor versatility of the tire frame.

[0003] If ordinary tire frames are used, they cannot adapt to the splicing angles of steel beams, and a car crane is needed for splicing. However, the car crane can only be unhooked after the steel beams are spliced ​​and formed, resulting in low efficiency of the car crane, and the steel beams are prone to overturning and collision, etc., which creates safety hazards. Therefore, it is necessary to provide an auxiliary splicing device for multi-angle folding beams, which can solve the problem in the prior art that the splicing of multi-folding steel beams requires the customization of special tire frames or the splicing of ordinary tire frames requires the cooperation of car cranes.

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Please see attached Figure 1 To Attachment Figure 3 An auxiliary splicing device for multi-angle folding beams, comprising a sliding base 01, a vertical force transmission platform 02, a lifting mechanism 03, a balance beam 04, a fine-tuning mechanism 05 and an anti-overturning mechanism 06; the sliding base 01 is arranged on the ground below the splicing ends of two adjacent sections of steel beams 09, the lower ends of a pair of vertical force transmission platforms 02 are slidably arranged on the sliding base 01, and a pair of balance beams 04 are liftably arranged on a pair of vertical force transmission platforms 02 through the lifting mechanism 03; each balance beam 04 is provided with a pair of anti-overturning mechanisms 06 and a plurality of fine-tuning mechanisms 05, and two adjacent sections of steel beams 09 are respectively adjustably placed on the fine-tuning mechanisms 05 on the top of a pair of balance beams 04, so that the splicing ends of the steel beams 09 are located between the pair of anti-overturning mechanisms 06.

[0025] The number of auxiliary splicing devices is set according to the number of sections of the steel beam 09 and the position of the splicing nodes. The sliding base 01 provides sliding adjustment along the length direction of the steel beam 09 for a pair of vertical force transmission platforms 02, so that two adjacent sections of the steel beam 09 can slide close to each other after being hoisted onto a pair of vertical force transmission platforms 02, thereby facilitating the splicing ends of the two sections of the steel beam 09.

[0026] The lifting mechanism 03 can use a large-sized jack. The lifting mechanism 03 provides vertical height adjustment for the steel beam 09, thereby ensuring that the spliced ​​ends of the two sections of the steel beam 09 are at the same elevation, ensuring accurate splicing, and the adjustment range of the lifting mechanism 03 can be adaptively selected according to the splicing height and angle of the steel beam 09. At the same time, the two ends of the steel beam 09 are lifted to different heights by the lifting mechanism 03, respectively, and the angle of the steel beam 09 and the splicing height of the previous section of the steel beam 09 can be accurately controlled.

[0027] The balance beam 04 is used to place the steel beam 09. The balance beam 04 can be set perpendicular to the length direction of the steel beam 09 to ensure stable support of the steel beam 09. The fine-tuning mechanism 05 can use a small-sized jack to fine-tune the height and angle of the steel beam 09 in a small range to further ensure the precise splicing of the steel beam 09. The anti-overturning mechanism 06 can use steel rods set in pairs. The steel rods are abutted on both sides of the steel beam 09 to prevent the steel beam 09 from tilting and ensure that the steel beam 09 remains stable after being hoisted on the balance beam 04, so that the truck crane can quickly unhook, reducing the time occupied by the truck crane, and also ensuring the stability of the steel beam 09 during the position and angle adjustment process and the splicing process.

[0028] Please see attached Figure 1 To Attachment Figure 3 The sliding base 01 includes a pair of base units, which are long strip structures arranged along the length direction of the steel beam 09, and the pair of base units are parallel to each other; the lower end of each vertical force transmission platform 02 is slidably connected to a pair of base units.

[0029] Preferably, the base unit can be made of square steel pipes, and the specifications and lengths of the square steel pipes can be adaptively selected according to actual adjustment and load requirements. It is used to provide installation and sliding for the vertical force transmission platform 02 and transmit the gravity of the steel beam 09 to the ground, with high stability in setting and use.

[0030] Please see attached Figure 2 and attached Figure 3 A first slide groove 011 is formed along the length direction of each base unit, and the vertical force transmission platform 02 is an inverted U-shaped structure. The lower ends of both sides of the vertical force transmission platform 02 can be slidably inserted into the first slide grooves 011 of a pair of base units.

[0031] A first slide groove 011 is provided on the square steel pipe, and the size of the first slide groove 011 can be adaptively adjusted according to actual use requirements. The vertical force transmission platform 02 can be formed by splicing three square steel pipes, and the square steel pipe specification of the vertical force transmission platform 02 is smaller than the square steel pipe specification of the sliding base 01.

[0032] The horizontal square steel pipe of the vertical force transmission platform 02 is used to install the jacking mechanism 03. The vertical square steel pipe of the vertical force transmission platform 02 is inserted into the first slide groove 011 to bear and transmit the gravity of the steel beam 09 and drive the steel beam 09 above it to slide along the first slide groove 011. After sliding into place, the vertical square steel pipe of the vertical force transmission platform 02 can be locked and fixed to the base unit by bolts and nuts, which is convenient for the splicing operation of the two sections of steel beams 09.

[0033] Please see attached Figure 2 and attached Figure 3 The balance beam 04 is in the form of an elongated strip, and a second slide groove 041 is formed along the length direction of the balance beam 04. The lower end of the anti-rollover mechanism 06 can be slidably inserted into the second slide groove 041, so that a pair of anti-rollover mechanisms 06 can abut against the two side surfaces of the steel beam 09.

[0034] The balance beam 04 can be made of a square steel tube, on which a second slide groove 041 is provided, and the size of the second slide groove 041 can be adaptively adjusted according to actual use requirements. The anti-overturning mechanism 06 can be made of a square steel rod, which is used to slide and insert into the second slide groove 041 and slide and adjust to the two sides of the steel beam 09 to prevent the steel beam 09 from tilting, and can adapt to steel beams 09 of different specifications and sizes. After the anti-overturning mechanism 06 slides into place, the anti-overturning mechanism 06 and the balance beam 04 can be locked and fixed by bolts and nuts to ensure the anti-overturning effect.

[0035] Please see attached Figure 3 The anti-overturning mechanism 06 is provided with a tie rod 07, the end of the tie rod 07 passes through the connecting plate 091 of the spliced ​​end of the steel beam 09, and is locked and fixed to the connecting plate 091 by a locking nut 071.

[0036] The tie rod 07 can be made of a steel bar, one end of which is welded to the anti-overturning mechanism 06, and the other end of which is threaded for screwing on the locking nut 071. When the anti-overturning mechanism 06 abuts against the side of the steel beam 09, the other end of the tie rod 07 passes through the bolt hole reserved on the connecting plate 091 at the spliced ​​end of the steel beam 09, and the locking nut 071 is screwed on the other end of the steel bar and abuts against the connecting plate 091. The connecting plate 091 is located between the anti-overturning mechanism 06 and the locking nut 071, thereby further improving the stability of the steel beam 09 on the balance beam 04, so that it can slide synchronously with the vertical force transmission platform 02.

[0037] Please see attached Figure 3 The side end of the balance beam 04 is provided with a slope measuring instrument 08 , and the slope measuring instrument 08 is arranged at the bottom of a steel beam 09 placed on the balance beam 04 .

[0038] The inclination angle of the steel beam 09 is measured by the slope measuring instrument 08, so as to ensure that the splicing angle of two adjacent sections of the steel beam 09 of the multi-angle folded beam meets the design requirements.

[0039] Please see attached Figure 4 and attached Figure 5 The slope measuring instrument 08 includes a connecting rod 081, a measuring disk 082 and a measuring rod 083; the horizontal section of the connecting rod 081 of the L-shaped structure is a telescopic section and is connected to the side end of the balance beam 04, and the middle part of the measuring rod 083 is rotatably arranged on the vertical section of the connecting rod 081 through a rotating shaft, so that the measuring rod 083 can be attached to the bottom surface of the steel beam 09 placed on the balance beam 04; the measuring disk 082 is fixedly arranged on the vertical section of the connecting rod 081.

[0040] The horizontal section of the connecting rod 081 can adopt a telescopic section structure composed of two round steel pipes, which is used to adjust the horizontal position of the measuring rod 083 so that it can move to fit the bottom of the inclined steel beam 09. The measuring rod 083 can rotate around the rotating shaft to fit the steel beam 09 with different inclination angles. When the measuring rod 083 rotates, it rotates relative to the measuring disk 082, so that the rotation angle of the measuring rod 083, that is, the inclination angle of the steel beam 09, can be measured by the measuring disk 082, which can improve the splicing accuracy of the angle of the steel beam 09.

[0041] Please see attached Figure 5 The measuring disk 082 is a circular structure, and angle scale lines are formed circumferentially at the edge of the measuring disk 082; the rotating axis of the measuring rod 083 is located at the center of the measuring disk 082, and the two ends of the measuring rod 083 extend to both sides of the measuring disk 082 and are aligned with the angle scale lines.

[0042] The measuring range of the angle scale line of the quasi-measuring disk 082 is 0°-180°. When the measuring rod 083 is in a horizontal state, the measuring rod 083 is aligned with the 0° angle of the angle scale line of the measuring disk 082. When the measuring rod 083 rotates relative to the measuring disk 082 and fits the bottom surface of the steel beam 09, the angle pointed by the measuring rod 083 on the angle scale line is the inclination angle of the steel beam 09.

[0043] Please see attached Figure 1 To Attachment Figure 5 , the method of using the utility model is:

[0044] (1) According to the length of the steel beam 09, the auxiliary splicing device of the utility model is placed at the corresponding splicing position on the construction site to ensure that an auxiliary splicing device is placed under the butt joint of two adjacent sections of the steel beam 09. An auxiliary splicing device is also placed under the non-splicing end of the steel beam 09 at both ends of the folding beam to ensure stable support for the first and last sections of the steel beam 09.

[0045] (2) The first section of steel beam 09 is hoisted by a truck crane and placed on the fine-adjustment mechanism 05 of the balance beam 04 of the first and second auxiliary splicing devices, and a pair of anti-overturning mechanisms 06 are moved along the second slide groove 041 to make them close to the two side surfaces of the first section of steel beam 09 to prevent the first section of steel beam 09 from overturning. Then the truck crane can be unhooked.

[0046] (3) Adjust the lifting mechanisms 03 at both ends of the first steel beam 09 to form a certain angle between the first steel beam 09 and the ground. The angle is determined according to the splicing angle of the first steel beam 09, so that the connecting plate 091 at the splicing end of the first steel beam 09 is perpendicular to the ground.

[0047] When each section of steel beam 09 is manufactured, the angle between the connecting plate 091 at its end and the steel beam 09 is customized to match the angle of the folding angle. During the splicing process, the connecting plates 091 of the two adjacent sections of steel beam 09 are at the same elevation and perpendicular to the ground. The connecting plates 091 of the two adjacent sections of steel beam 09 can be spliced ​​to complete the splicing of the two adjacent sections of steel beam 09.

[0048] (4) The truck crane hoists the second steel beam 09 and places it on the fine-tuning mechanism 05 of the balance beam 04 of the third and fourth auxiliary splicing devices, and moves a pair of anti-overturning mechanisms 06 along the second slide groove 041 to make them close to the two side surfaces of the second steel beam 09 to prevent the second steel beam 09 from overturning. Then the truck crane can remove the hook.

[0049] (5) Adjust the lifting mechanism 03 at one end of the second steel beam 09 close to the first steel beam 09 so that the connecting plate 091 of the second steel beam 09 and the connecting plate 091 of the first steel beam 09 are at the same elevation.

[0050] (6) Adjust the lifting mechanism 03 at the other end of the second steel beam 09, and measure the angle of the second steel beam 09 by the slope measuring instrument 08. When the slope value is consistent with the design drawing, stop adjusting the lifting mechanism 03.

[0051] (7) The tie rod 07 is passed through the high-strength bolt hole reserved on the connecting plate 091 of the second section of the steel beam 09 and is locked by the locking nut 071. The vertical force transmission platform 02 is pushed by the driving device to slide slowly along the first slide groove 011 on the sliding base 01 until the connecting plates 091 of the first section and the second section of the steel beam 09 are in contact with each other.

[0052] (8) Remove the locking nut 071, and adjust the elevation of the connecting plate 091 of the two sections of the steel beam 09 through the fine-tuning mechanism 05 so that the bolt holes on the connecting plates 091 of the two sections of the steel beam 09 are completely aligned and the two connecting plates 091 are completely fitted together. Insert high-strength bolts to tighten the two connecting plates 091, so that the first section and the second section of the steel beam 09 are spliced ​​at a specified angle.

[0053] (9) Repeat the above steps (4)-(8) to install the third section of steel beam 09 and subsequent steel beams 09 until all steel beams 09 are spliced ​​together to form a multi-angle folded beam.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
