[0018] Beneficial effects

[0019] The present invention provides a device for constructing concrete beam-column joints. Compared with the prior art, it has the following advantages:

[0020] 1. This device is used for the construction of concrete beam-column nodes. It realizes the rapid adjustment and positioning of the template through mechanical transmission.

It ensures that the template and the beam-column surface fit with an accuracy of ±1mm through a multi-dimensional adjustment system and mechanical linkage clamping, which can effectively avoid leakage. At the same time, the graded fixed structure forms a stable whole through the pre-embedded fixation of support bolts and columns, the rigid connection of support blocks and support plates, and the close fit of side templates and beam-column surfaces. There is no displacement under the action of concrete's own weight, so that the node forming size error is ≤3mm, meeting high-standard construction requirements and solving the quality problems of traditional templates caused by inaccurate positioning and unstable fixation.

[0022] 3. This device is used for the construction of concrete beam-column nodes. By adjusting the height of the folding plate and adapting the size of the adjustment component, it can cover the cross-sectional sizes of beam-column nodes from 300mm×300mm to 800mm×800mm. There is no need to customize templates for nodes of different specifications, which greatly reduces construction costs, improves equipment utilization, and solves the problems of poor versatility and high cost of traditional templates.

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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-6 , the present invention provides a technical solution:

[0032] A device for constructing a concrete beam-column node comprises a column 1 and a beam 2. The beam 2 is mounted on one side of the column 1. A plurality of support bolts 3 are embedded on one side of the column 1 and below the beam 2. The surface of the support bolts 3 is threadedly connected to a support block 4. A support plate 5 is mounted on the top of the support block 4. The interior of the support plate 5 is adjusted by an adjustment component 6 to allow a bottom plate 7 to slide. A clamping mechanism 8 is provided on the surface of the bottom plate 7 for forming a casting groove at the beam-column node. The clamping mechanism 8 comprises:

[0033] The clamping assembly 81 includes a sliding rod 811 slidably mounted on the bottom of the base plate 7. One end of the sliding rod 811 is fixedly connected to a connecting plate 812. A folding plate 813 is slidably connected to the interior of the connecting plate 812. The surface of the folding plate 813 is provided with multiple groups of fixing holes 814. The inner surfaces of the fixing holes 814 are threadedly connected to fixing bolts 815. The surface of the fixing bolts 815 is threadedly connected to the inner threads of the connecting plate 812. One end of the folding plate 813 is fixedly mounted to a side template 816 by bolts. The bottom of the side template 816 is in contact with the top of the base plate 7.

[0034] The control component 82 is arranged at the bottom of the base plate 7 and is used to realize the sliding operation of the side template 816.

[0035] The support bolts 3 are made of 8.8 grade high-strength bolts with a pre-embedded depth of 200mm. The support blocks are made of Q235 steel, and the support plates are made of 12mm thick Q355 steel plates.

[0036] The side template 816 is installed on one end of the folding plate 813 by bolts. The side template 816 can be flexibly disassembled and assembled through multiple sets of bolts, and the height of the side template 816 can be flexibly adjusted through the fixing bolts 815 and the corresponding fixing holes 814.

[0037] The template is quickly adjusted and positioned through mechanical transmission. The bidirectional screw 62 of the adjustment component 6 cooperates with the linkage component 63 to complete the vertical lifting and horizontal fine-tuning of the base plate 7 in a short time. The bevel gear of the clamping mechanism 8 and the transmission screw 91 are transmitted to quickly drive the side template 816 to open and close. The entire process does not require multiple disassembly and reinstallation. Compared with the traditional manual installation method, the template installation time is shortened by more than 40%, which greatly reduces the labor intensity. Especially in the construction of batch nodes, the efficiency improvement is more significant.

[0038] In this embodiment, the control component 82 includes a control box 821 installed at the bottom of the base plate 7. One side of the control box 821 is rotatably connected to a control rod 822. One end of the control rod 822 extends through the interior of the control box 821 and is fixedly connected to a control bevel gear 823. The surface of the control bevel gear 823 causes the sliding rod 811 to slide through the transmission component 9, and the interior of the control box 821 is slidably connected to the surface of the sliding rod 811.

[0039] The other end of the control rod 822 extends through the outside of the control box 821 and is fixedly connected to the control block.

[0040] In this embodiment, the transmission assembly 9 includes a transmission screw 91 rotatably installed inside the control box 821. The surface of the transmission screw 91 is connected to the internal thread of the sliding rod 811. One end of the transmission screw 91 is fixedly connected to a transmission bevel gear 92. The surface of the transmission bevel gear 92 is meshed with the surface of the control bevel gear 823.

[0041] The transmission screw rod 91 and the transmission bevel gear 92 are symmetrically designed and there are two sets.

[0042] In this embodiment, the upper surface of the base plate 7 is in contact with the bottom of the beam 2, one side of the base plate 7 is in contact with one side of the column 1, the inner side of the side template 816 is in contact with the surface of the beam 2, and one side of the side template 816 is in contact with one side of the column 1.

[0043] The side formwork 816 panel is made of 15-21mm thick phenolic coated plywood with a smooth surface, a waterproof grade ≥ IPX7, and can be reused more than 50 times;

[0044] The bottom plate 7 is made of 12-18 mm thick Q235 steel plate.

[0045] In this embodiment, the adjustment component 6 includes an adjustment motor 61 installed on one side of the support plate 5. One end of the output shaft of the adjustment motor 61 is fixedly connected to a bidirectional screw rod 62 through a coupling. The surface of the bidirectional screw rod 62 is connected to the internal rotation of the support plate 5. The surface of the bidirectional screw rod 62 causes the mounting plate 64 to slide through the linkage component 63, and the mounting plate 64 is installed at the bottom of the base plate 7.

[0046] The regulating motor 61 is a three-phase asynchronous reduction motor.

[0047] In this embodiment, the linkage assembly 63 includes a linkage block 631, the interior of the linkage block 631 is threadedly connected to the surface of the bidirectional screw rod 62, the top of the linkage block 631 is rotatably connected to a linkage rod 632, and one end of the linkage rod 632 is rotatably connected to the bottom of the mounting plate 64.

[0048] In this embodiment, a symmetrical limiting sliding groove 10 is formed on the top of the support plate 5 , and the inner surface of the limiting sliding groove 10 is slidably connected to the surface of the linkage block 631 .

[0049] The linkage block 631 can be limited in horizontal sliding by the limiting sliding groove 10 .

[0050] In this embodiment, a positioning rod 11 is slidably connected to the interior of the support plate 5 , and the top end of the positioning rod 11 is fixedly connected to the bottom of the base plate 7 .

[0051] The bottom plate 7 can be used to limit the vertical sliding of the bottom plate 7.

[0052] The multi-dimensional adjustment system and mechanical linkage clamping ensure that the template and the beam and column surface fit with an accuracy of ±1mm, which can effectively avoid leakage. At the same time, the graded fixing structure forms a stable whole through the embedded fixation of the support bolts 3 and the column 1, the rigid connection of the support block 4 and the support plate 5, and the close fit of the side template 816 and the beam and column surface. There is no displacement under the action of the concrete's own weight, so that the node forming size error is ≤3mm, meeting high-standard construction requirements and solving the quality problems of traditional templates caused by inaccurate positioning and unstable fixation.

[0053] By adjusting the height of the folding plate 813 and adapting the size of the adjustment component 6, the cross-sectional dimensions of the beam-column nodes ranging from 300mm×300mm to 800mm×800mm can be covered. There is no need to customize templates separately for nodes of different specifications, which greatly reduces construction costs, improves equipment utilization, and solves the problems of poor versatility and high cost of traditional templates.

[0054] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] The device realizes the precise installation and firm fixation of the beam-column node template through three-level coordinated operation. First, the support fixing mechanism firmly fixes the support plate 5 to the side of the column 1 through the threaded connection of the support bolt 3 embedded in the column 1 and the support block 4, forming the basic support layer of the device. The horizontal height of the support plate 5 can be fine-tuned by rotating the support block 4 to ensure the accuracy of the overall installation benchmark. Secondly, after the adjustment component 6 is started, the adjustment motor 61 drives the bidirectional screw rod 62 to rotate. Since the threads at both ends of the bidirectional screw rod 62 are in opposite directions, the two sets of linkage blocks 631 slide synchronously in opposite directions along the limiting slide groove 10, driving the linkage rod 632 to push the installation plate 64 and the bottom plate 7 to perform vertical lifting and horizontal fine-tuning until the upper surface of the bottom plate 7 is aligned with the bottom of the beam body 2 and one side of the bottom plate 7. It fits tightly with the side of the column 1 to complete the positioning of the bottom of the template. Finally, the clamping mechanism 8 starts to work, and the control rod 822 is turned to make the control bevel gear 823 drive the transmission bevel gears 92 and the transmission screw 91 on both sides to rotate. The transmission screw 91 drives the sliding rod 811 to move horizontally, thereby driving the connecting plate 812, the folding plate 813 and the side template 816 to move toward the beam-column direction. At the same time, the folding plate 813 slides in the connecting plate 812 and is locked with the fixing bolt 815. The height of the side template 816 is adjusted to adapt to the size of the beam. Finally, the inner side of the side template 816 is tightly fitted with the surface of the beam and the side of the column. The two sets of side templates 816, the bottom plate 7, the column 1 and the beam 2 are jointly enclosed to form a sealed casting trough to meet the concrete pouring requirements.
