Several preset steel bars 2 are correspondingly installed with auxiliary pouring mechanisms. Several auxiliary pouring mechanisms are installed in the cap beam 1. After the installation is completed, the cap beam 1 and the pier column 3 are fixedly connected in cooperation with concrete.

[0058] When the cap beam 1 lifting and installation device is used, firstly, the pier 3 is erected at the construction site, and prefabricated steel bars are installed on the pier 3. Then, the auxiliary casting mechanism is installed on the prefabricated steel bars. After the installation of the auxiliary casting mechanism is completed, the cap beam 1 is installed on the pier 3. At the same time, it is ensured that the auxiliary casting mechanism is installed in the cap beam 1 to complete the installation of the cap beam 1 and the pier 3. At the same time, concrete is poured between the cap beam 1 and the pier 3 to ensure the stable connection between the cap beam 1 and the pier 3.

[0059] Reference Figure 4 and Figure 5 The cap beam 1 includes several evenly arranged pouring cavities 11, which are opened at the connection between the cap beam 1 and the pier 3. The pouring cavity 11 is truncated cone-shaped, and the inner diameter of the pouring cavity 11 close to the pier 3 is larger than the inner diameter of the pouring cavity 11 away from the pier 3. Several evenly distributed guide rails 12 are arranged on the inner wall of the pouring cavity 11. The number of guide rails 12 is four, and the guiding direction of the guide rails 12 is the same as the busbar of the truncated cone-shaped pouring cavity 11. The guide rails 12 are connected to the auxiliary pouring device 4. An air guide hole 13 is opened on the end of the cap beam 1 away from the pouring cavity 11, and several pouring cavities 11 are connected to the air guide hole 13.

[0060] When the cap beam 1 is installed on the pier 3, the auxiliary pouring device 4 installed on the preset steel bar 2 is installed in the pouring cavity 11 accordingly, and concrete is poured into the pouring cavity 11 through the auxiliary pouring device 4. While pouring concrete into the pouring cavity 11, the air in the pouring cavity 11 is discharged through the air guide hole 13. When the pouring cavity 11 is full of concrete, the concrete is filled into the air guide hole 13. By observing the concrete liquid level in the air guide hole 13, the filling amount of concrete poured into the pouring cavity 11 is observed. When the air guide hole 13 is full of concrete, the concrete pouring is stopped.

[0061] Reference Figure 4 and Figure 5The pier 3 includes a plurality of uniformly arranged gas cavities 34, each of which is provided at one end of the pier 3 in contact with the cap beam 1, each of which is provided with an auxiliary pouring device 4, and a partition 38 is fixedly installed at the bottom of the gas cavity 34, and a concrete cavity 31 is provided at one end of the partition 38 away from the gas cavity 34, and the concrete cavity 31 is provided in the pier 3. The partition 38 is provided with a plurality of uniformly distributed gas outlet holes 37, one end of which is connected to the gas cavity 34, and the other end of which is connected to the concrete cavity 31.

[0062] A gas generator 35 is installed in the gas cavity 34. The gas generator 35 can generate gas. The gas generator 35 is a prior art and will not be described in detail here. The gas generator 35 is electrically connected to the control switch 36. The trigger quick switch is installed on the auxiliary pouring device 4. The control switch 36 is used to control the gas generator 35 to work and generate gas.

[0063] Several concrete cavities 31 are evenly opened in the pier 3, and two adjacent concrete cavities 31 are connected to each other through concrete connecting pipes 33. Among the several concrete cavities 31, two concrete cavities 31 are connected to one end of a concrete conduit 32, and the two concrete cavities 31 connected to the concrete conduit 32 are symmetrically opened in the pier 3, and concrete enters the concrete conduit 32 through the other end of the concrete conduit 32 and flows into the concrete cavity 31.

[0064] The preset steel bars 2 fixedly installed on the pier 3 are correspondingly penetrated in the gas cavity 34 and the concrete cavity 31. The end of the preset steel bar 2 away from the concrete cavity 31 is arranged above the top of the pier 3. The preset steel bar 2 is fixedly penetrated on the partition 38. The preset steel bar 2 and the partition 38, the concrete cavity 31 and the gas cavity 34 are all on the same axis.

[0065] When the cap beam 1 is installed, the preset steel bars 2 with the auxiliary pouring device 4 installed are installed in the pouring cavity 11, and the bottom wall of the cap beam 1 is in contact with the top of the pier 3. After the cap beam 1 and the pier 3 are installed, the cap beam 1 drives the auxiliary pouring device 4 to work, and the auxiliary pouring device 4 works to trigger the control switch 36. The control switch 36 transmits a signal to the gas generator 35 through an electrical connection, and the gas generator 35 starts to generate gas, and at the same time, concrete is filled into two concrete cavities 31 connected to the concrete conduit 32 through the concrete conduit 32, and at the same time, concrete is filled into other concrete cavities 31 through the concrete connecting pipe 33. The gas generator 35 generates gas, and the gas pressurizes the concrete cavity 31 through the gas outlet 37. The concrete in the concrete cavity 31 flows into the auxiliary pouring device 4 under pressure, and the concrete is filled into the pouring cavity 11 through the auxiliary pouring device 4, completing the installation of the cap beam 1.

[0066] Reference Figure 4 and Figure 5 The auxiliary pouring device 4 includes several guide sleeves 41, one end of each guide sleeve 41 is correspondingly sleeved on several baffles 416, a sleeve cavity 412 is provided on the inner wall of the guide sleeve 41, and the bottom of the sleeve cavity 412 is connected to the concrete cavity 31. An embedding groove 411 is provided on the end of the guide sleeve 41 away from the concrete cavity 31, and a control switch 36 is installed in the embedding groove 411. A steel sleeve 42 is slidably penetrated in the guide sleeve 41, and the steel sleeve 42 is fixedly sleeved on the preset steel bar 2. The steel sleeve 42 is adaptively adjusted and replaced according to the diameter of the preset steel bar 2 to ensure that the steel sleeve 42 is tightly sleeved with the preset steel bar 2. An abutment block 43 is fixedly connected to one end of the steel sleeve 42, and the abutment block 43 can be correspondingly and tightly embedded in the embedding groove 411. When the abutment block 43 is embedded in the embedding groove 411, the abutment block 43 triggers the control switch 36.

[0067] A fixing ring 44 is fixedly sleeved on the steel sleeve 42 , and one end of a buffer spring 45 is fixedly connected to the fixing ring 44 . One end of the buffer spring 45 away from the fixing ring 44 is fixedly connected to the top of the inner wall of the guide sleeve 41 . The buffer spring 45 is sleeved on the steel sleeve 42 .

[0068] Two groups of perfusion holes 413 are provided on the outer wall of the guide sleeve 41. Each group of perfusion holes 413 includes four perfusion holes 413 evenly provided on the wall of the guide sleeve 41. One end of the perfusion hole 413 is connected to the perfusion cavity 11, and the other end of the perfusion hole 413 is connected to the sleeve cavity 412. Each group of perfusion holes 413 is coaxially provided with a corresponding guide hole 414. The guide hole 414 is provided on the inner wall of the guide sleeve 41 on the side away from the perfusion hole 413. The aperture of the perfusion hole 413 is larger than the aperture of the guide hole 414. A connecting rod 417 is inserted into the guide hole 414. The connecting rod 417 fits tightly with the guide hole 414. The end of the connecting rod 417 away from the guide hole 414 is correspondingly inserted into the perfusion hole 413. The end of the connecting rod 417 away from the guide hole 414 is fixedly sleeved on the slider 415. The slider 415 is slidably connected in the guide rail 12. A baffle plate 416 is also fixedly sleeved on the connecting rod 417 . The baffle plate 416 is disposed in the sleeve cavity 412 . The baffle plate 416 fits tightly with the injection hole 413 .

[0069] When the cap beam 1 is installed on the pier 3, the auxiliary pouring device 4 starts to work, and the slider 415 is slidably installed in the guide rail 12. As the inner diameter of the pouring cavity 11 gradually changes, the slider 415 moves horizontally toward the guide sleeve 41, and at the same time, the baffle 416 moves away from the pouring hole 413. The sleeve cavity 412 is connected to the pouring cavity 11 through the pouring hole 413. When the abutment block 43 abuts against the top of the pouring cavity 11, under the action of the gravity of the cap beam 1, the abutment block 43 drives the steel sleeve 42 to move toward the pier 3. When the steel sleeve 42 moves, the buffer spring 45 is stretched, which plays a buffering role on the steel sleeve 42 and the guide sleeve 41. When the cap beam 1 abuts against the pier 3, the abutment block 43 is nested in the embedding groove 411 and the control switch 36 is triggered at the same time. The control switch 36 controls the gas generator 35 to start generating air. Under the action of air pressure, the concrete poured in the concrete cavity 31 enters the sleeve cavity 412 through the bottom of the sleeve cavity 412, and flows into the pouring cavity 11 through the pouring hole 413, thereby realizing the concrete pouring work of the pouring cavity 11.

After the auxiliary pouring mechanism is installed, the cap beam 1 is installed on the pier column 3, and at the same time, the auxiliary pouring mechanism is ensured to be installed in the cap beam 1, and the installation of the cap beam 1 and the pier column 3 is completed. At the same time, concrete is poured between the cap beam 1 and the pier column 3 to ensure a stable connection between the cap beam 1 and the pier column 3.

[0071] The embodiment of the present application also discloses a method for using a device for hoisting and installing the cap beam 1 .
