[0002] Reinforced concrete beams are beams made of reinforced concrete materials. Reinforced concrete beams can be made into independent beams, or they can be made into beam-slab floor slabs with reinforced concrete slabs, or they can be made into single-layer or multi-layer frames with reinforced concrete columns.

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, the method for horizontally lifting a reinforced concrete beam segment includes a reinforced concrete beam segment 1 and a handle 2 arranged outside the reinforced concrete beam segment 1. A counterweight device 3 is arranged outside the reinforced concrete beam segment 1. Both end sides of the reinforced concrete beam segment 1 are provided with transverse lifting holes 101. The inside of the transverse lifting hole 101 is provided with a steel bar 4 extending out of the hole. The four ends of the handle 2 are provided with rings 201. The lifting steps of the reinforced concrete beam segment 1 are as follows: Step 1: Put the ring 201 of the handle 2 on the steel bar 4 outside the horizontal lifting hole 101, and tie the ring 201 and the steel bar 4 together, and hook the crane hook 5 on the middle intersection of the handle 2; Step 2: slowly lift the reinforced concrete beam section 1 and observe whether it is level; Step 3: If tilt occurs, place a counterweight device 3 on the reinforced concrete beam segment 1, and level the reinforced concrete beam segment 1 by adjusting the counterweight device 3 and its position.

[0020] In this embodiment, the counterweight device 3 is composed of a sling 301 and a carrying bag 302. The number of the slings 301 and the carrying bag 302 are both two. The two slings 301 are placed on the top of the reinforced concrete beam section 1. The carrying bags 302 are fixedly installed on the left and right ends of the bottom of the sling 301. The carrying bags 302 are located on the left and right sides of the reinforced concrete beam section 1. The two slings 301 are parallel to each other and perpendicular to the longitudinal axis of the reinforced concrete beam section 1.

[0021] Specifically, when one end of the reinforced concrete beam section 1 and any side of the end are warped, the counterweight device 3 needs to be moved to the end, and the counterweight material needs to be added to the carrier bag 3 on the warped side to adjust the balance.

[0022] The weight material filled in the carrying bag 3 can be made from local materials, such as bricks or stones; the handle 2 is formed by two steel bars or steel wire ropes tied together at the intersection in the middle.

[0023] In this embodiment, the ring 201 is put on the steel bar 4, and the ring 201 is fixedly connected to the steel bar 4 by a cross-binding method. A U-shaped clamping ring is arranged on the outside of the steel bar 4, and a hand-tightened bolt is threadedly installed on the end of the U-shaped clamping ring. The ring 201 is located between the U-shaped clamping ring and the reinforced concrete beam section 1.

[0024] It should be noted that after the ring 201 is tied to the steel bar 4, the U-shaped clamp can be fixed on the steel bar 4 and the ring 201 can be shielded by manually tightening the hand bolt, so as to avoid the ring 201 from shifting on the steel bar 4 during the lifting of the reinforced concrete beam section 1, thereby making the lifting of the reinforced concrete beam section 1 safer.

[0025] In this embodiment, the method for judging whether the reinforced concrete beam section 1 is horizontal in step 2 is as follows: when the reinforced concrete beam section 1 is slowly lifted, a transparent hose whose length exceeds the length of the reinforced concrete beam section 1 is selected, and a sufficient amount of water is injected into the hose, and the water surface at one end of the hose is kept flush with the center of the upper edge of one end of the reinforced concrete beam section 1, and the water surface at the other end of the hose is checked to see whether it is flush with the center of the upper edge of the other end of the reinforced concrete beam section 1, thereby judging whether the two ends of the reinforced concrete beam section 1 are flush; The method for judging whether both sides of the reinforced concrete beam segment 1 are horizontal in step 2 is as follows: when the reinforced concrete beam segment 1 is slowly lifted, a transparent hose whose length exceeds the width of the reinforced concrete beam segment 1 is selected, sufficient water is injected into the hose, and the water surface at one end of the hose is kept flush with the center of the upper edge of one side of the reinforced concrete beam segment 1, and the water surface at the other end of the hose is checked to see whether it is flush with the center of the upper edge of the other side of the reinforced concrete beam segment 1, thereby judging whether both sides of the reinforced concrete beam segment 1 are flush.

[0026] In this embodiment, on the basis of embodiment 1, the present invention provides a technical solution: a method for horizontally lifting a reinforced concrete beam segment, comprising a reinforced concrete beam segment 1 and a handle 2 arranged outside the reinforced concrete beam segment 1, a counterweight device 3 is arranged outside the reinforced concrete beam segment 1, longitudinal lifting holes 102 are arranged at both end surfaces of the reinforced concrete beam segment 1, and the longitudinal lifting holes 102 are provided with steel bars 4 extending out of the holes, and rings 201 are arranged at the four ends of the handle 2. The lifting steps of the reinforced concrete beam segment 1 are as follows: Step 1: Put the ring 201 of the handle 2 on the steel bar 4 outside the longitudinal lifting hole 102, and tie the ring 201 and the steel bar 4 together, and hook the crane hook 5 on the middle intersection of the handle 2; Step 2: slowly lift the reinforced concrete beam section 1 and observe whether it is level; Step 3: If tilt occurs, place a counterweight device 3 on the reinforced concrete beam segment 1, and level the reinforced concrete beam segment 1 by adjusting the counterweight device 3 and its position.

[0027] In this embodiment, the method for adjusting the counterweight device 3 and its position to level the reinforced concrete beam segment 1 is as follows: When one end of the reinforced concrete beam section 1 is tilted, the counterweight device 3 needs to be moved to that end, and weights of the same weight need to be added to the carrying bags 3 on both sides to adjust the balance; When one side of the reinforced concrete beam section 1 is tilted, the counterweight device 3 is placed in the middle, and a counterweight needs to be added to the carrier bag 302 on that side to adjust the balance; When one end of the reinforced concrete beam section 1 and any side of the end are warped, the counterweight device 3 needs to be moved to the end, and counterweight material needs to be added to the carrier bag 3 on the warped side to adjust the balance.

[0028] It should be noted that the handle 2 is made of steel wire rope or steel bar material, the ferrule 201 is formed by processing and welding the end of the handle 2 using a three-two splicing method, and the four ferrules 201 are of the same size.

[0029] The reinforced concrete beam section 1 can be prepared by prefabrication or on-site cutting. During prefabrication, embedded holes need to be set in the reinforced concrete beam section 1. During on-site cutting, drilling is required.

[0030] In addition, the distances from the transverse lifting hole 101 to the upper surface and end face of the reinforced concrete beam segment 1 are equal, the distances from the longitudinal lifting hole 102 to the upper surface and side face of the reinforced concrete beam segment 1 are equal, the distances from the transverse lifting hole 101 and the longitudinal lifting hole 102 to the upper surface of the reinforced concrete beam segment 1 are smaller than the distances to the lower surface of the reinforced concrete beam segment 1, and the transverse lifting hole 101 and the longitudinal lifting hole 102 can be through holes or blind holes.

The total length of the bridge is 100m and the width of the bridge deck is 15m. The entire project requires the hoisting of 20 prefabricated reinforced concrete beam segments 1. Each reinforced concrete beam segment 1 is 6m long, 1.5m wide, 0.5m high, and weighs about 3t.

[0032] 1) The reinforced concrete beam segment 1 is prefabricated in the factory, wherein two rows of 3 holes in each row, a total of 6 holes, with a diameter of 36 mm are set at the ends and sides of the two ends. The uppermost hole for inserting reinforcement is 0.2 m away from the top surface of the beam. HPB400 reinforcements are inserted into the holes for inserting reinforcements, and both sides of the reinforcements extend out of the holes by 0.3 m. 2) Select two steel wire ropes with a length of 7.4m and a diameter of 20mm, tie them with 4mm galvanized iron wire at the intersection in the middle, and reserve 120mm at both ends, and use the three-two splicing method to obtain a ring 201 with a diameter of about 38mm to form a handle 2; 3) Put the ring 201 at the end of the handle 2 onto the steel bar 4 outside the insertion hole, and tie the ring 201 and the steel bar 4 with a galvanized iron wire with a diameter of 4mm; 4) Use a crane hook 5 with a load-bearing capacity of 5 tons to hook the handle 2 and slowly lift it up, select a transparent hose with a length of 7 meters and a diameter of 15 mm, fill it with water, and place it at both ends of the reinforced concrete beam segment 1, and at the same time place a counterweight device 3 horizontally on the reinforced concrete beam segment 1; 5) Observe the water in the hose and the upper surface of the reinforced concrete beam segment 1 to determine whether it is horizontal. It is found that one end of the reinforced concrete beam segment 1 sinks and the center of gravity shifts to one end; 6) Place the counterweight device 3 at the raised end of the reinforced concrete beam section 1, and add the same counterweight to the two carrier bags 302 until the reinforced concrete beam section 1 is horizontal.

[0033] 7) Repeat steps 3), 4), 5) and 6) to complete the subsequent lifting.

In order to ensure production safety, it was decided to reinforce and renovate the factory building. The main work included dismantling some old beam sections, drilling holes in the beam sections and inserting reinforcement bars at key locations. The beam sections were 5m long, 1.2m wide and 0.5m high.

It is found that one side of the reinforced concrete beam segment 1 sinks and the center of gravity shifts to one side; 6) Place a counterweight device 3 on the top of the reinforced concrete beam section 1, and add counterweight to the tilted side loading bag 302 until the reinforced concrete beam section 1 is level.

[0036] 7) Repeat steps 3), 4), 5) and 6) to complete the subsequent lifting.

[0037] Example 3 A foundation pit support beam section project involves the foundation pit support work of a high-rise building. The total depth of the foundation pit is 15m and the width is 20m. In order to ensure the safety and stability of the foundation pit, the project requires the hoisting of 15 prefabricated reinforced concrete support beam sections. Each beam section is 6m long, 1m wide, 0.5m high and weighs 2.5t.

[0038] 1) Complete the prefabrication of reinforced concrete beam segment 1 in the factory, punch holes at both ends or both sides of reinforced concrete beam segment 1, set two rows, 3 holes in each row, a total of 6, 36mm diameter transverse lifting holes 101 or longitudinal lifting holes 102 (i.e., reinforcement holes), the uppermost reinforcement hole is 0.2m away from the top surface of the beam, insert HPB400 reinforcement 4 into the reinforcement hole, and both sides of the reinforcement 4 extend out of the hole by 0.4m; 2) Select two steel wire ropes with a length of 7.2m and a diameter of 20mm, tie them with 4mm galvanized iron wire at the intersection in the middle, and reserve 120mm at both ends, and use the three-two splicing method to obtain a ring 201 with a diameter of about 38mm to form a handle 2; 3) Put the ring 201 at the end of the handle 2 onto the steel bar 4 outside the insertion hole, and tie the ring 201 and the steel bar 4 with a galvanized iron wire with a diameter of 4mm; 4) Use a crane hook 5 with a load-bearing capacity of 5 tons to hook the handle 2 and slowly lift it up. Select two transparent hoses, one with a length of 7 meters and a diameter of 15 mm, and the other with a length of 2 meters and a diameter of 15 mm. Fill them with water, place the 7-meter-long transparent hose at both ends of the reinforced concrete beam segment 1, and place the 2-meter-long transparent hose on both sides of the reinforced concrete beam segment 1. At the same time, place a counterweight device 3 horizontally on the reinforced concrete beam segment 1; 5) Observe the water in the hose and the upper surface of the reinforced concrete beam segment 1 to determine whether it is horizontal. It is found that one end of the reinforced concrete beam segment 1 sinks and one side sinks, causing the center of gravity to shift to one end. At the same time, the center of gravity shifts to one side. 6) Place the counterweight device 3 at the raised end of the reinforced concrete beam section 1, and add different counterweights to the two carrier bags 302 until the reinforced concrete beam section 1 is horizontal.
