Compared with the traditional cast-in-place floor, steel bar truss floor support plate can be directly laid on the beam and then poured, without the need for formwork, greatly shortening the construction period. Steel bar truss floor support plate is welded by steel bars and thin steel plates, and has a relatively light weight, which can effectively reduce the overall load of the building. When lifting the steel bar truss floor support plate, a metal rod is usually inserted into the marked position of the steel bar truss floor support plate, and then the lifting process is completed through the lifting device.

[0003] Most of the side walls of the steel bar truss floor support plate are not marked, which results in the need for manual measurement of the lifting insertion position each time. At this time, the distance from the insertion rod to the center of the floor support plate is required to be equal to the distance from the insertion rod to the edge of the floor support plate, so as to ensure the balance of the pressure at both ends during lifting.

[0082] Embodiment two, please refer to Figure 2 - Figure 8 The application is a kind of steel truss floor support plate construction hoisting device, based on embodiment one, the measuring assembly 21 includes a gear one 213 rotatably connected to the inner wall of the shell 212, the side wall of the gear one 213 is sleeved with a belt one 214;

[0083] Wherein, the two gears one 213 are in meshing state, when measuring, two workers each pull one end of a belt one 214, and move towards the two ends of the floor support plate, at this time, the gear one 213 rotates while the belt one 214 gradually expands outward.

[0086] Wherein, the number of gears of the gear two 221 is twice the number of gears of the gear one 213, when the gear one 213 rotates twice, it will drive the gear two 221 to rotate one circle through the transmission gear 223.

[0087] The hoisting assembly 11 includes a T-shaped plate 113 fixedly connected to the end of the pulling belt 111, a recess 114 is formed in the side wall of the contact plate 112;

[0088] Wherein, after the contact plate 112 is inserted into the balance position, at this time, the worker puts the T-shaped plate 113 into the inner wall of the recess 114, so that the connecting frame 13 can drive the contact plate 112 and the floor support plate to perform the hoisting process through the pulling belt 111;

[0089] When the belt one 214 expands outward, the belt one 214 will pass through the square tube 313 and the rolling column 312, due to the increase of the contact area, this makes the resistance increase when the belt one 214 passes through the above area, the resistance will act on the L-shaped plate 311, so that the L-shaped plate 311 drives the relaxed belt two 222 to be in the straightened state again, avoiding the phenomenon of relaxation of the belt two 222 due to external pulling force, causing inaccurate positioning.

[0090] The adaptive assembly 12 comprises sliding hydraulic plates 123 slidingly connected at the inner wall of the fixed frame 122;

[0091] The inside of the hydraulic groove 121 is always filled with hydraulic oil before use, and the sliding hydraulic plates 123 slide relative to each other, and the inner wall of the hydraulic groove 121 and the bottom of the sliding hydraulic plate 123 form a sealed space;

[0092] After the measurement is completed, the contact plate 112 can be inserted into the indicated position of the floor support plate at this time, and then the connecting frame 13 drives the floor support plate by pulling the belt 111 to perform the lifting process, at this time the weight of the plurality of floor support plates acts on the reinforcement inside the floor support plate, so that the reinforcement pressure acts on the top of the sliding hydraulic plate 123, so that part of the sliding hydraulic plate 123 slides downward, and the downward sliding sliding hydraulic plate 123 will press the hydraulic oil inside the hydraulic groove 121, so that the remaining sliding hydraulic plate 123 slides upward.

[0093] The friction assembly 31 comprises a square tube 313 connected through the side wall of the L-shaped plate 311;

[0094] When the belt 214 passes through the square tube 313 and the rolling column 312, the rolling column 312 will increase the sliding resistance of the belt 214, and the resistance is transmitted to the L-shaped plate 311 through the rolling column 312, so that the L-shaped plate 311 carries the belt 222. Synchronously move outward;

[0095] Through the application of the adaptive assembly 12, the contact surface between the sliding hydraulic plate 123 and the reinforcement is increased to avoid the phenomenon of deviation caused by the blowing of the external environmental wind force when the contact surface is too small.

[0096] The hook assembly 32 comprises a hook 321 fixedly connected to the end of the belt 214 away from the gear 213;

[0097] Wherein, the worker can hang the hook 321 on the edge of the floor support plate after reaching the edge position of the floor support plate, and after the hook 321 reaches the edge position, the position of the L-shaped plate 311 will be the balance position of the two ends of the floor support plate.

[0098] One specific application of the embodiment is that before use, the connecting frame 13 is installed at the lifting arm position, and then the connecting frame 13 is transported to the required position by the lifting arm;

[0099] When in use, one of the hooks 321 is hung on one end of the floor deck, and then the other hook 321 is picked up and moved to the other end of the floor deck. During this process, as the belt 1 214 extends outward, the belt 1 214 will drive the gear 1 213 to rotate on the inner wall of the shell 212, and the rotating gear 1 213 drives the gear 2 221 to rotate in the same direction through the transmission gear 223. During the process of the belt 1 214 extending outward, since the gear ratio of the gear 1 213 and the gear 2 221 is two to one, that is, when the gear 1 213 rotates two circles, the gear 2 221 will rotate one circle. As the belt 1 214 extends outward, when the gear 2 221 rotates, the belt 2 222 will become loose. When the belt 1 214 passes through the square tube 313 and the roller 312, the contact surface increases, which increases the resistance of the belt 1 214 when passing through the above area. The resistance acts on the L-shaped plate 311, causing the L-shaped plate 311 to drive the loose belt 2 222 to be straightened again. This process ensures that the L-shaped plate 311 is always at the center of the outward length of the belt 1 214 during its outward movement. When the hooks 321 are hung on the two ends of the floor deck, the positions of the two L-shaped plates 311 are in the balance area of ​​the floor deck. At this time, the distances between the two L-shaped plates 311 and the edge of the floor deck are equal, and the distances between the two L-shaped plates 311 and the center of the floor deck are also equal.

[0100] After the measurement is completed, the contact plate 112 can be inserted into the indicated position of the floor deck, such as Figure 2 As shown, the T-shaped plate 113 is clamped inside the groove 114. After confirming that the contact plate 112 is stable, the connecting frame 13 then drives the floor deck through the pulling belt 111 to perform the lifting process;

[0101] During this process, the weight of multiple floor decks will act on the steel bars of the floor decks, so that the pressure of the steel bars will act on the top of the sliding hydraulic plates 123, causing some of the sliding hydraulic plates 123 to slide downward, and the downward-moving sliding hydraulic plates 123 will compress the hydraulic oil in the hydraulic tank 121, causing the remaining sliding hydraulic plates 123 to slide upward. By using the above components, the contact area between the sliding hydraulic plates 123 and the steel bars is increased during operation of the equipment, avoiding the contact area being too small, which may cause deviation under the blowing of external wind.

[0102] After reaching the desired position, the staff can remove the hook 321. At this time, the turbine spring 224 will release the accumulated mechanical power, drive the gear 2 221 and the gear 1 213 to rotate, and recover the belt 1 214 and the belt 2 222 remaining outside.
