However, the existing reinforcement method results in significant waste of formwork, the support structure is not reusable, and it is inconvenient to use and dismantle. Furthermore, existing formwork suffers from common quality defects such as bulging and grout leakage, as well as aesthetic issues. To avoid these problems, a beam-column joint formwork support structure that solves the aforementioned issues is needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a formwork support structure for beam-column joints, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: a formwork support structure for beam-column joints, comprising: a foundation pile, an inner steel bar connected to the outer wall of the foundation pile, an inner metal chain provided on the outer wall of the inner steel bar, a supporting steel bar connected to the outer wall of the foundation pile, a reinforcing chain provided on the outer wall of the supporting steel bar, a column formwork provided at the top of the foundation pile, a groove provided on the outer wall of the column formwork, a clamp installed on the outer wall of the column formwork, a column body filled in the inner wall of the column body, a beam body provided on the outer wall of the column body, a beam formwork installed on the outer wall of the column body, a support plate connected to the outer wall of the beam formwork, a metal rod sleeved on the inner wall of the beam formwork, a connecting plate sleeved on the outer wall of the metal rod, a pushing screw sleeved on the inner wall of the connecting plate, a tightening nut sleeved on the outer wall of the pushing screw, a circular plate movably connected to the side of the pushing screw away from the tightening nut, a tightening spring connected to the outer wall of the circular plate, and a tightening plate connected to the other side of the tightening spring away from the circular plate.

[0005] Preferably, the bottom of the inner steel bar is disposed in the inner cavity of the foundation pile, and a plurality of inner metal chains are arranged on the outer wall of the inner steel bar.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The formwork support structure at the beam-column joint, by setting up column formwork, beam formwork, clamping plates, and pushing screws, allows for additional support at the beam-column joint when additional support is needed. The beam formwork is installed on the side of the column formwork, and the metal rod penetrates the inner cavity of the beam formwork. When the clamping nut is turned, the pushing screw moves closer to the beam formwork, thereby compressing the clamping spring on the device and pressing the clamping plate tightly against the outer wall of the beam formwork. Thus, after the beam is poured, the beam formwork can be used for side support.

[0014] 2. The formwork support structure at the beam-column joint uses beam formwork, connecting plates, push screws, and clamping springs to support the side of the column at the beam joint. The push screws on both sides of the connecting plate work with the clamping springs for support. The beam formwork wraps around three sides of the beam in a "U" shape. The support structure is simple, strong, convenient, quick, and reusable, thus avoiding common quality problems such as poor quality, bulging, and grout leakage at the joint after molding. Furthermore, after the beam-column joint is formed, the excess part of the metal rod is removed to maintain the overall aesthetic appearance of the column. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A formwork support structure for beam-column joints includes: a foundation pile 1, with inner reinforcing bars 2 connected to the outer wall of the foundation pile 1, and inner metal chains 3 provided on the outer wall of the inner reinforcing bars 2; supporting reinforcing bars 4 connected to the outer wall of the foundation pile 1, and reinforcing chains 5 provided on the outer wall of the supporting reinforcing bars 4; a column formwork 6 provided at the top of the foundation pile 1, with grooves 7 on the outer wall of the column formwork 6; clamps 8 installed on the outer wall of the column formwork 6; a column body 9 filled in the inner wall of the column formwork 6; a beam body 10 provided on the outer wall of the column body 9; and beam formwork installed on the outer wall of the column body 9. The outer wall of the beam formwork 11 is connected to a support plate 12. The inner wall of the beam formwork 11 is fitted with a metal rod 13. The outer wall of the metal rod 13 is fitted with a connecting plate 14. The inner wall of the connecting plate 14 is fitted with a push screw 15. The outer wall of the push screw 15 is fitted with a tightening nut 16. A circular plate 17 is movably connected to the side of the push screw 15 away from the tightening nut 16. A tightening spring 18 is connected to the outer wall of the circular plate 17. A tightening plate 19 is connected to the other side of the tightening spring 18 away from the circular plate 17.

[0023] The bottom of the inner steel bar 2 is set in the inner cavity of the foundation pile 1, and multiple inner metal chains 3 are arranged on the outer wall of the inner steel bar 2. Since the bottom of the inner steel bar 2 is set in the inner cavity of the foundation pile 1, when the foundation pile 1 is buried in the ground, the inner steel bar 2 extends upward and protrudes from the ground, and multiple inner metal chains 3 fix multiple inner steel bars 2.

[0024] The bottom of the supporting steel bar 4 is set in the inner cavity of the foundation pile 1, and multiple reinforcing chains 5 are wrapped around the outer wall of the supporting steel bar 4. By setting the bottom of the supporting steel bar 4 in the inner cavity of the foundation pile 1, the supporting steel bar 4 on the device is vertically upward on the foundation pile 1. The length of the supporting steel bar 4 is adapted according to the structural requirements of the column. Multiple reinforcing chains 5 are used to bind the supporting steel bar 4 around the outer wall, so that the multiple supporting steel bars 4 do not swing or become unstable.

[0025] The column template 6 consists of four pieces, which fit together to form a square. The four column templates 6 are installed on the device, and square notches are provided on both sides of the column template 6. When the four column templates 6 fit together to form a square, the notches on both sides of the column template 6 fit together, thereby preventing concrete from overflowing from the edge of the column template 6 during the pouring process.

[0026] The inner wall of the groove 7 is adapted to the outer wall of the beam 10, and the beam template 11 is installed on the outer side of the column template 6. By adapting the inner wall of the groove 7 on the device to the outer wall of the beam 10, the columns 9 on the device can be extended outward to form beams 10. Before the beam 10 is poured, the beam template 11 is first erected along the outer wall of the groove 7. The beam template 11 is made of 15mm thick plywood and is a U-shaped special template, so that the inner cavity of the beam template 11 can be poured with concrete.

[0027] The outer wall of the push screw 15 is provided with external threads, and the outer wall of the push screw 15 is threadedly connected to the inner wall of the clamping nut 16. Because the outer wall of the push screw 15 is provided with external threads, the inner wall of the clamping nut 16 is provided with internal threads, and the push screw 15 is threadedly connected to the clamping nut 16. When the clamping nut 16 is twisted, the outer wall of the push screw 15 moves closer to the beam template 11, thereby pushing the push screw 15 to continuously squeeze the circular plate 17 and compress the clamping spring 18.

[0028] Both the clamping plate 19 and the circular plate 17 are circular, and the clamping plate 19 is attached to the outer wall of the beam template 11. Since both the clamping plate 19 and the circular plate 17 on the device are circular, when the circular plate 17 on the device is pushed closer to the clamping plate 19 by the push screw 15, the clamping plate 19 will be attached to the outer wall of the beam template 11, and the clamping spring 18 will gradually compress between the circular plate 17 and the clamping plate 19, thereby making the beam template 11 located on both sides of the beam 10 more and more tightly attached to the outer wall of the beam 10.

[0029] The connecting plate 14 is equipped with a level 20 on its outer wall, and the inner cavity of the level 20 contains a water bubble. By using the level 20 on the outer wall of the connecting plate 14, when the connecting plate 14 is installed evenly on both sides of the beam formwork 11, the water bubble in the inner cavity of the level 20 can be observed to determine whether the connecting plate 14 is in a horizontal state.

[0030] The working principle involves first setting up a column template 6, a beam template 11, a clamping plate 19, and a pushing screw 15. When additional support is needed at the joint between the side of the column 9 and the beam 10, the beam template 11 is installed on the side of the column template 6, with the metal rod 13 penetrating the inner cavity of the beam template 11. Twisting the clamping nut 16 causes the pushing screw 15 to move closer to the beam template 11, thus compressing the clamping spring 18 and simultaneously pressing the clamping plate 19 tightly against the outer wall of the beam template 11. Therefore, after the beam 10 is poured, the beam template 11 can provide lateral support. The work involves setting up beam template 11, connecting plate 14, push screw 15, and clamping spring 18, so that the side of the column 9 on the device and the joint of the beam 10 are supported by the push screw 15 on both sides of the connecting plate 14 and the clamping spring 18. The beam template 11 wraps around the three sides of the beam 10 in a "U" shape. The support structure on the device is simple, strong, convenient and quick, and can be reused, thus avoiding common quality problems such as poor quality, bulging and leakage at the joint after molding. After the beam-column joint is formed, the excess part of the metal rod 13 is removed to keep the column aesthetically pleasing.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
