Description
Technical Field
[0001] This invention relates to the field of building equipment technology, and in particular to a beam bottom reinforcement device and reinforcement method applicable to building construction. Background Technology
[0002] Beams are the core horizontal load-bearing components of a building, transferring the floor load to columns or walls. They are classified according to the stress they bear, such as main beams, secondary beams, and connecting beams; and according to the material, such as reinforced concrete beams and steel beams. The core of their construction lies in precise formwork support, standardized rebar tying, and dense pouring and curing of concrete to ensure structural safety.

The excessively concentrated load can cause the beams under the slab to bear excessive bending moments, resulting in bending moment deformation of the beams.

[0017] In specific application scenarios, the rapid erection module 7 is mainly suitable for the rapid erection stage in the rapid erection process.

[0019] In specific application scenarios, the separation module 8 is mainly used in the separation stage of the separation process. That is, the separation module 8 uses the insertion slot 801 and the separation frame 802 to enable the device to quickly and conveniently separate from the supporting steel pipe 5 after the device has completed the support of the beam, so as to carry out the next support system erection. This greatly improves the speed and difficulty of personnel operation and increases the efficiency of the device in erecting the beam bottom support. The limit rod 803, guide buckle 804 and lever 805 can effectively lock the position of the insertion slot 801 and the stabilizing platform 1, thereby avoiding the situation where the separation frame 802 is not installed properly on the stabilizing platform 1 and collides or gets stuck with other structures, thus ensuring the stable operation of the device.
[0020] A method for reinforcing the bottom of beams used in building construction, using the aforementioned device for reinforcing the bottom of beams used in building construction, includes the following steps: Step 1: After confirming the location of the beam that needs to be supported and reinforced, set up the stabilizing platform 1 on the ground under the beam, unfold the vertical frame 4 and keep it vertically locked to the stabilizing platform 1. Step 2: Place the support plate 6 and steel pipe 5 on the stabilizing platform 1 and the vertical frame 4, with the steel pipe 5 at an angle. Use the quick-erecting module 7 to gradually push the steel pipe 5 using the pushing block 3, gradually changing the steel pipe 5 from an angled position to a vertical position. During this process, place the support plate 6 against the bottom of the beam (after confirming the location of the beam requiring support and reinforcement, erect the stabilizing platform 1 on the ground under the beam, unfold the vertical frame 4 and keep it vertically locked to the stabilizing platform 1. At this time, the locking pin 718 is inserted into the receiving seat 720 under the elastic force of the spring 719. Place the support plate 6 and steel pipe 5 on the stabilizing platform 1 and the vertical frame 4, with the steel pipe... 5. With the steel pipe 5 tilted, insert the round rod 715 on the lower support 714 into the lower slot 716 at the bottom of the steel pipe 5. Push the push block 3 to slide in the mounting groove 2, so that the push block 3 abuts against the outside of the lower support 714. Continuously and lightly press the pedal 740, so that the air in the elastic airbag 738 is delivered to the hollow tube 733 through the air guide tube, so that the air pressure in the hollow tube 733 continuously increases, thereby pushing the piston 734 to move in the hollow tube 733. This pushes the push rod 735 to continuously move the push block 3 towards the vertical frame 4, thereby gradually turning the steel pipe 5 from tilted to vertical. During this process, the upper slot 713 at the top of the steel pipe 5 will... The round rod 715 on the upper support 709 is connected to the screw rod 707. After connection, the support plate 6 connected to the screw rod 707 is pushed upward and finally contacts the bottom of the beam. The pedal 740 is pressed to make the push block 3 continue to move. The limit block 728 will engage with the rack 726 when the push block 3 moves to prevent the push block 3 from moving backward. After the steel pipe 5 is completely vertical, the lower support seat 714 will be pushed onto the wooden board 725 by the push block 3. The first pin 711 and the second pin 717 are inserted into the first pin seat 710 and the second pin seat 712 on the same side to form a whole. When the height of the bottom of the beam is too high, the screw rod 706 is rotated to make the screw rod 707... 06. Drive the lifting frame 701 connected to the transmission block 705 to rise on the vertical frame 4, or rotate the double nut 708 and the upper support 709 to adjust the position of the double nut 708 and the upper support 709 on the screw 707. If the steel pipe 5 is tilted on the vertical frame 4 due to the force when placing it, or if the round rod 715 is not perfectly aligned with the upper slot 713 and the lower slot 716, lightly press the lever 729 to make the lever 729 drive the long rod 727 to rotate against the torque of the coil spring 732, so that the limit block 728 is released from the engagement with the rack 726, pull the push block 3 back, adjust the position of the steel pipe 5, and then continue. Step 3: After the steel pipe 5 is pushed to the vertical position, use the separation module 8 to separate the stabilizing platform 1 and the vertical frame 4 from the steel pipe 5 and the support plate 6, in preparation for the next point of beam bottom support (after the steel pipe 5 supports the beam bottom, push the push block 3 back to its original position to expose the separation frame 802, grasp the lever 805 and push it gently to make the limit rod 803 slide backward against the elastic force of the spring 807, release the lock on the separation frame 802, pull the separation frame 802 out of the insertion slot 801, pull the locking pin 718 out of the receiving seat 720, lower the lifting frame 701, move the stabilizing platform 1, so that the whole formed by the steel pipe 5, the lower support seat 714 and the support plate 6 can be separated from the stabilizing platform 1 from the notch formed by the insertion slot 801).
