It also includes a support component for enhancing the stability between the foundation beam 13 and the short column body 2, and the support component is installed between the foundation beam 13 and the short column body 2; a support component for sealing the front and rear sides of the gap between the two foundation beams 13, and the support component is installed on the outside of the two foundation beams 13; a reinforcement component for enhancing the firmness of the support component, and the reinforcement component is installed on the outside of the support component. There are two groups of reinforcement components, which are symmetrically distributed.

[0033] The support assembly includes a threaded sleeve 14 embedded in the interior of the short column body 2. A plurality of protrusions 15 are provided on the outside of the threaded sleeve 14. The protrusions 15 are used to increase the contact surface between the threaded sleeve 14 and the concrete. Two symmetrically distributed angle brackets 16 are installed on the outside of the short column body 2 near its upper end, and the upper end surface of the angle bracket 16 is movably abutted against the lower end surface of the foundation beam 13.

[0034] A diagonal brace 17 is fixedly installed on the inner side of the angle bracket 16, and the shape formed by the angle bracket 16 and the diagonal brace 17 is a triangle. A bolt 18 is fixedly installed on the angle bracket 16 corresponding to the threaded sleeve 14, and the connection between the bolt 18 and the threaded sleeve 14 is a threaded connection. A pad 19 is fixedly installed on the angle bracket 16 corresponding to the bolt 18. The pad 19 prevents the bolt 18 from being embedded in the inner side of the angle bracket 16, can expand the operating space of the bolt 18, and the bolt 18 passes through the pad 19.

[0035] A plurality of dowel bars 11 equidistantly distributed around the circumference are inserted into the through hole 9 on the short column body 2. In order to enable the dowel bars 11 to be smoothly placed into the through hole 9 of the component, a bending portion is provided on the dowel bar 11. A plurality of equidistantly distributed hoops 12 are fixed to the outer side of the dowel bar 11 by iron wire, and the plurality of dowel bars 11 and the plurality of hoops 12 are located between two foundation beams 13.

[0036] The support assembly includes a steel formwork 20 that is movably fitted with the two foundation beams 13. There are two groups of steel formworks 20, which are symmetrically distributed. The steel formworks 20 are used to shape the concrete poured between the two foundation beams 13. At the same time, two symmetrically distributed support plates 21 are fixedly installed on the lower end of the steel formwork 20, and the support plates 21 are fixedly connected to the angle bracket 16 by bolts 22.

[0037] Working principle: After completing the cushion construction, first hoist the cap-short column integrated component to the place where the cast-in-place pile 3 picks out the steel bars 10. After alignment, the steel bars 10 picked out from the top of the cast-in-place pile 3 are placed in the through hole 9 of the cap body 1. After completing the positioning of the cast-in-place pile 3 and the cap-short column component, insert the reinforcement 11 into the through hole 9 of the short column body 2. After locating the axis position, tie the hoop 2 12. After the insertion reinforcement 11 is positioned and tied, hoist the foundation beam 13 to complete the positioning of the foundation beam 13. The two ends of the foundation beams 13 are close to each other, and the steel bars picked out at one end avoid each other, leaving enough space for inserting the steel bars. After the foundation beam 13 is hoisted, concrete is poured.

[0038] Before hoisting and positioning the foundation beam 13, personnel install bolt 18 into the threaded sleeve 14 and use bolt 18 to fix the angle bracket 16 to the outside of the short column body 2. Later, when hoisting the foundation beam 13, the angle bracket 16 can increase the support surface of the short column body 2 on the foundation beam 13, thereby increasing the stability of the foundation beam 13 during installation.

[0039] Before pouring concrete, personnel use bolts 22 to fix two steel formworks 20 on the outside of the two foundation beams 13 to shape the concrete poured between the two foundation beams 13. The two steel formworks 20 are supported and positioned by angle brackets 16, which effectively enhances the stability during the concrete pouring process.

[0040] Example 2: Please refer to Figure 5 、 Figure 8 This embodiment further explains Example 1. The reinforcement component includes two symmetrically distributed L-shaped plates 24. The lower end of the L-shaped plate 24 movably abuts the limit seat 23, and the connection between the limit seat 23 and the steel template 20 is a fixed connection. The L-shaped plate 24 is movably plugged into the limit seat 23 through the embedding groove 33, and the end of the embedding groove 33 away from the steel template 20 is in an open state, and one end of the embedding groove 33 is in an open state, which facilitates the insertion of the L-shaped plate 24 into the limit seat 23.

[0041] The two L-shaped plates 24 are both movably embedded with a movable inner plate 25 at one end close to each other. The two inner plates 25 are fixedly connected at one end close to each other through a connecting seat 26. Two symmetrically distributed balls 27 are installed on the outer side of the inner plate 25, and the balls 27 are movably embedded in the interior of the L-shaped plate 24. The balls 27 are used to prevent the inner plate 25 from separating from the L-shaped plate 24.

[0042] The L-shaped plate 24 is in rolling contact with the inner panel 25 through the limiting straight groove 28. An adjusting bolt 29 is rotatably installed at the inner center of the connecting seat 26 through a bearing. A threaded sleeve 30 is threadedly sleeved on the outer side of the adjusting bolt 29. Two symmetrically distributed hinged seats 31 are fixedly installed on the outer side of the threaded sleeve 30. A diagonal tie rod 32 is hingedly installed on the inner side of the hinged seat 31. The adjusting bolt 29 can drive the two L-shaped plates 24 to move closer to or away from each other through the diagonal tie rod 32, and the end of the diagonal tie rod 32 away from the hinged seat 31 is movably hinged to the inner panel 25.

[0043] In this embodiment, since the support points of the two steel templates 20 are located on the lower side of the steel templates 20, the steel templates 20 may be deformed or expanded when subjected to pressure or external force. In order to effectively fix the templates, reinforcement components need to be installed on the upper side of the two steel templates 20 before pouring concrete.

[0044] When installing the reinforcement assembly, personnel insert the lower ends of the two L-shaped plates 24 into the embedded grooves 33 on the two limit seats 23 respectively. Then, personnel use tools or equipment to rotate the adjusting bolt 29 so that the adjusting bolt 29 drives the threaded sleeve 30 to move upward. During the upward movement, the threaded sleeve 30 drives the two L-shaped plates 24 to move closer to each other through the two inclined rods 32 until the two L-shaped plates 24 are against the limit seats 23, thereby preventing the steel formwork 20 from being expanded when pouring concrete.

[0045] Example 3: Please refer to Figure 5-Figure 7 This embodiment further explains Example 2. A limiting assembly is installed between the limiting seat 23 and the L-shaped plate 24. The limiting assembly includes two movable pins 34 that are movably embedded in the limiting seat 23 and can move. The two pins 34 are symmetrically distributed. The two pins 34 are provided with a beveled edge on the side away from the steel template 20, and the beveled edge is located at one end of the two pins 34 close to each other. The beveled edge can reduce the friction resistance between the pins 34 and the L-shaped plate 24. Two symmetrically distributed extension seats 35 are fixedly embedded on the outer side of the limiting seat 23 corresponding to the pins 34.

[0046] The two pin rods 34 are fixedly connected to a gasket 36 at one end away from each other, and the gasket 36 can move inside the limit seat 23 and the extension seat 35. The gasket 36 is used to prevent the pin rod 34 from separating from the limit seat 23. The side of the gasket 36 away from the pin rod 34 is movably abutted against a spring 37. A slot 38 is provided on the outer side of the L-shaped plate 24 corresponding to the pin rod 34, and the lower end of the slot 38 is open.

[0047] In this embodiment, when the two L-shaped plates 24 move against the limit seat 23, the L-shaped plates 24 will drive the two pins 34 to move away from each other through the oblique edge portion. When the slot 38 on the L-shaped plate 24 moves to the pin 34, the pin 34 will be embedded in the slot 38 under the drive of the spring 37, so that when the cast-in-place concrete is dry and demoulded, the personnel first loosen the bolt 22 and then rotate the adjustment bolt 29 to move the two L-shaped plates 24 away from each other. In the process, the L-shaped plate 24 will drive the steel formwork 20 to move through the pin 34, so that the steel formwork 20 is separated from the concrete, thereby assisting the two steel formworks 20 to be quickly demoulded. Since the lower end of the slot 38 is in an open state, when the steel formwork 20 is separated from the concrete, the L-shaped plate 24 can directly separate from the limit seat 23 through the slot 38.
