Description

Technical Field

[0001] The invention relates to the technical field of hanging beam installation, and in particular to an auxiliary hanging beam device for prefabrication of T beams. Background Art

[0002] At present, the production of beams and slabs mainly relies on manual processing and production. The prefabrication of beams and slabs mainly includes the following processes: ① Installing and fixing the base; ② Binding and making the steel skeleton; ③ Setting up the outer formwork and fixing the end formwork; ④ Checking the inner formwork; ⑤ Pouring concrete; ⑥ Removing the formwork; ⑦ Tensing the steel strands (there is no such process for the prefabrication of non-prestressed beams and slabs); ⑧ Curing to the finished product; ⑨ Grouting and sealing the anchor. The various processes of beam and slab prefabrication are mainly based on manual work, which not only has low production efficiency, but also low product precision and high safety risks. In the process of T-beam prefabrication construction, the support of the end formwork is an important link. Ensuring that the prefabricated structural dimensions of the beam and slab and the slope of the end of the beam and slab meet the design requirements is a construction focus. In actual construction, the traditional construction process requires multiple corrections and positioning. If the formwork is not firmly supported, there will be problems such as T-beam end concrete leakage caused by formwork running and structural dimensions not meeting the design requirements. Therefore, an auxiliary beam hanging device is needed to help the installation of the hanging beam.

[0003] Among them, the patent with announcement number CN221116747U discloses a flexible prefabricated T-beam bottom hanging beam device, including a hanging beam mechanism, and also includes a support frame, a sliding frame, a reciprocating motor, a threaded rod, a slider, a threaded sleeve, a connecting plate and a laser marking light. The inner side of the top end of the support frame is connected to the outer side of the sliding frame, the right end of the sliding frame is connected to the inner end of the reciprocating motor, the output end of the reciprocating motor is connected to the right end of the threaded rod, the threaded rod is rotatably connected to the inner side of the sliding frame, the inner side of the sliding frame is also slidably connected to the outer side of the slider, a threaded sleeve is provided on the inner side of the slider, the inner wall of the threaded sleeve is threadedly connected to the outer wall of the threaded rod, the bottom end of the slider is connected to the bottom end of the hanging beam mechanism, the output end of the hanging beam mechanism is connected to the outer side of the connecting plate, the middle part of the bottom end of the connecting plate is connected to the top of the laser marking light, and a projection mechanism is provided on the outer side of the sliding frame.

[0004] When the structure is in use, the reciprocating motor is operated to rotate the threaded rod inside the slide frame. The threaded rod is screwed with the threaded sleeve to make the slider slide to the corresponding position inside the slide frame and drive the connecting piece to move, so that the laser marking light stops after acting at the end position, and then the prefabrication construction is completed. The laser marking projection can assist in measurement, so that the prefabrication position is more accurate and the reliability is improved. However, the structure is not easy to position the various ends of the suspension beam during installation, resulting in low stability during the installation of the suspension beam. Summary of the invention

[0005] The present invention provides an auxiliary beam hanging device for T-beam prefabrication, aiming to solve the problems raised in the above background technology.

[0006] The present invention is implemented in this way. The present invention provides the following technical solutions: an auxiliary beam hanging device for T-beam prefabrication, comprising a support frame, on which a connecting assembly is provided;

[0007] The connecting assembly comprises a guide cylinder arranged in the middle of the support frame, a plurality of first connecting rods with adjustable angles are hingedly connected to the outer side of the guide cylinder, and one end of each of the first connecting rods is hingedly connected to a second connecting rod with adjustable angles, a positioning block is arranged at the bottom of the plurality of second connecting rods, and a shaft pin seat hingedly connected to the corresponding second connecting rod is fixedly arranged on one side of each of the positioning blocks;

[0008] A first positioning plate is provided at the bottom of each of the positioning blocks, and a second positioning plate is provided at the top of each of the first positioning plates, a plurality of angle-adjustable reinforcing rods are hinged on the outer side of the first positioning plate, and a limited support plate is fixedly provided at the bottom of each of the reinforcing rods, a plurality of angle-adjustable first electric push rods are hinged on the outer side of the second positioning plate, and each of the first electric push rods is respectively located at the top of the corresponding reinforcing rod, a connecting frame is fixedly provided at one end of the first electric push rod, and the connecting frame cover is provided on the reinforcing rod and hinged to the reinforcing rod.

[0009] It can be seen that in the above technical solution, the output end of the first electric push rod extends to drive the connecting frame to drive the reinforcing rod to rotate along the axial point of the connection between the reinforcing rod and the first positioning plate, so that the reinforcing rod drives the limit support plate to deflect, and makes each limit support plate gather or spread, and the limit support plate and the reinforcing rod are distributed in a triangular shape, so that each limit support plate and the reinforcing rod can be located at the end of the T-beam and on both sides of the end, so that the limit support plate can be easily wrapped around the end of the T-beam to avoid shaking of the T-beam during installation and lifting, which causes the T-beam to be offset during installation.

[0010] Optionally, in a possible embodiment, a plurality of the second connecting rods are provided with a sliding groove on one side, and a slider is slidably connected in each of the sliding grooves, a spring is fixedly provided on the plurality of sliders, a limiting ring is provided on the top of the second connecting rod, a plurality of connecting sleeves are provided on the limiting ring, and one end of each of the springs extends to the corresponding connecting sleeve and is fixedly connected to the connecting sleeve, a plurality of cross bars are fixedly provided on the limiting ring, and one end of each of the cross bars is rotatably connected to a guide sleeve, and a plurality of the guide sleeves extend to the support frame and are slidably connected to the support frame.

[0011] It can be seen that in the above technical solution, the second connecting rod deflection slider slides in the slide groove, and the displacement of the slider by the traction force when the second connecting rod is deflected will drive the spring to be stressed. The second connecting rod is positioned through the elasticity of the spring itself, so that the second connecting rod can be subjected to a certain resistance when it is deflected, which is used to ensure the stability of the second connecting rod when it is deflected, and the limit ring slides on the support frame through the guide sleeve through the elasticity of the spring, which makes it easy for the second connecting rod to be fully deployed while ensuring that each second connecting rod is evenly stressed, making it easy to install the T-beam and also easy to demold the T-beam during the prefabrication construction of the T-beam, avoiding large wear between the end and the template and causing damage to the T-beam.

[0012] Optionally, in a possible embodiment, a second electric push rod is provided above the guide cylinder, the second electric push rod is installed on the support frame by bolts, and the output end of the second electric push rod extends to the top of the guide cylinder and is detachably connected to the guide cylinder by bolts, a plurality of lifting rods are provided on the outside of the second electric push rod, a column is provided at the bottom of the guide cylinder, the column is fixed on the support frame, the guide cylinder is sleeved on the outside of the column and is slidably connected to the column, the tops of multiple lifting rods all pass through the support frame and extend to the top of the support frame, the bottoms of multiple lifting rods all extend to the outside of the guide cylinder and are detachably connected to the guide cylinder by bolts, a locking plate is provided on the top of the lifting rod, multiple positioning blocks and second connecting rods are triangularly distributed along the axis point of the support frame, and each positioning block is rotatably connected to the corresponding second positioning plate.

[0013] It can be seen that in the above technical solution, after the second electric push rod is started, the output end of the second electric push rod drives the guide cylinder to slide on the column. When the guide cylinder is displaced, it will drive the first connecting rod to be displaced, so that the second connecting rod is rotated along the axis point of the connection between the second connecting rod and the support frame through the traction force when the first connecting rod is displaced, and then each positioning block can be unfolded, so that each positioning block is easy to cover the three ends of the T-beam respectively, and it is easy to position each end of the T-beam at the same time, thereby ensuring the stability of the T-beam during hoisting.

[0014] The present invention has the following advantages:

[0015] 1. The present invention drives the first connecting rod to move when the guide cylinder moves, so that the second connecting rod rotates along the axis point of the connection between the second connecting rod and the support frame through the traction force when the first connecting rod moves, and then each positioning block is unfolded, so that each positioning block is easily covered at the three ends of the T beam, and each end of the T beam is easily positioned at the same time, ensuring the stability of the T beam during hoisting;

[0016] 2. The present invention extends the drive connection frame through the output end of the first electric push rod to drive the reinforcing rod to rotate along the axis point of the connection between the reinforcing rod and the first positioning plate, so that the reinforcing rod drives the limit support plate to deflect, and makes each limit support plate gather or spread, and the limit support plate and the reinforcing rod are distributed in a triangular shape, so that each limit support plate and the reinforcing rod can be located at the end of the T beam and both sides of the end, so that the limit support plate can be easily wrapped around the end of the T beam, so as to avoid the T beam shaking during installation and lifting, which causes the T beam to deviate during installation;

[0017] 3. The second connecting rod deflection slider of the present invention slides in the slide groove. The displacement of the slider by the traction force when the second connecting rod is deflected will drive the spring to be stressed. The second connecting rod is positioned by the elasticity of the spring itself, so that the second connecting rod can be subjected to a certain resistance when deflected, so as to ensure the stability of the second connecting rod when deflected;

[0018] 4. The limit ring of the present invention slides on the support frame through the guide sleeve by the elasticity of the spring, which makes it easy to fully unfold the second connecting rod while ensuring that each second connecting rod is evenly stressed, and is easy to install the T-beam and demould the T-beam during the prefabrication construction of the T-beam, thereby avoiding large wear between the end and the template causing damage to the T-beam;

[0019] To summarize, through the corresponding coordinated use of various structures, each positioning block is respectively covered on the three ends of the T-beam, which is easy to position each end of the T-beam at the same time, ensuring the stability of the T-beam during hoisting. The limiting support plate and the reinforcing rod are distributed in a triangle, so that each limiting support plate and the reinforcing rod can be located at the end of the T-beam and both sides of the end, which makes it easy for the limiting support plate to be wrapped around the end of the T-beam to avoid shaking of the T-beam during installation and hoisting, which causes the T-beam to be offset during installation. The limiting ring slides on the support frame through the guide sleeve through the elasticity of the spring, which makes it easy for the second connecting rod to be fully deployed while ensuring that each second connecting rod is evenly stressed, making it easy to install the T-beam and also easy to demold the T-beam during the prefabrication construction process to avoid damage to the T-beam caused by large wear between the end and the template.

[0035] A slide groove 13 is provided on one side of the plurality of second connecting rods 4, and a slider 14 is slidably connected in each slide groove 13, and a spring 15 is fixedly provided on the plurality of sliders 14.

[0036] A second electric push rod 20 is arranged above the guide cylinder 2, and the second electric push rod 20 is installed on the support frame 1 by bolts, and the output end of the second electric push rod 20 extends to the top of the guide cylinder 2 and is detachably connected to the guide cylinder 2 by bolts, and a plurality of lifting rods 21 are arranged on the outside of the second electric push rod 20, and a column 22 is arranged at the bottom of the guide cylinder 2, and the column 22 is fixed on the support frame 1, and the guide cylinder 2 is sleeved on the outside of the column 22 and is slidably connected to the column 22, and the tops of multiple lifting rods 21 all penetrate the support frame 1 and extend to the top of the support frame 1, and the bottoms of multiple lifting rods 21 all extend to the outside of the guide cylinder 2 and are detachably connected to the guide cylinder 2 by bolts, and a locking disk 23 is arranged on the top of the lifting rod 21, and multiple positioning blocks 5 and second connecting rods 4 are triangularly distributed along the axis point of the support frame 1, and each positioning block 5 is rotatably connected to the corresponding second positioning disk 8.

[0037] When using the above structure, the staff installs the device on the crane. When assisting the installation of the T-beam, the second electric push rod 20 is started, and the output end of the second electric push rod 20 drives the guide cylinder 2 to slide on the column 22. When the guide cylinder 2 is displaced, it will drive the first connecting rod 3 to be displaced, so that the second connecting rod 4 is rotated along the axis point of the connection between the second connecting rod 4 and the support frame 1 through the traction force when the first connecting rod 3 is displaced, and then each positioning block 5 is unfolded, so that each positioning block 5 is easy to cover the three ends of the T-beam respectively, and it is easy to position each end of the T-beam at the same time, ensuring the stability of the T-beam during hoisting.
