It is necessary to build a funnel formwork on the side of the pouring joint, and through opening holes in the upper floor slab, pour the concrete into the funnel formwork from the openings in the upper floor slab to complete the joint pouring.

[0003] Due to the funnel formwork support in the above traditional joint pouring method, an inevitable concrete inclined block will be left after pouring, which needs to be cut manually using cutting machinery. And due to the construction position at the top of the column and the high concrete strength of the column, the cutting is difficult and consumes a lot of labor. Summary of the Invention

[0009] Furthermore, in the above-mentioned PEC beam-column node casting device structure, the shape of the opening is a rectangle, and the width of the opening is the same as the width of one side where the polygonal tube overlaps with the rectangular side plate.

[0010] Furthermore, in the above-mentioned PEC beam-column node casting device structure, the opening is located at the upper part of the rectangular side plate, and the upper edge of the polygonal tube is flush with the upper edge of the rectangular side plate.

[0030] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the embodiments and with reference to the drawings.

[0031] Please refer to Figures 1 to 7The specific embodiment of the present invention relates to a PEC beam-column node casting device, comprising two symmetrical casting mold monomers 1, the casting mold monomer 1 comprising a rectangular side plate 11 and a rectangular bottom plate 12, one side of the rectangular side plate 11 is vertically connected to the lower side of the rectangular side plate 11, the rectangular side is provided with an opening 111, and a polygonal tube 13 arranged in a vertical direction is connected to the opening 111, and a movable part 14 is provided in the polygonal tube 13, and the movable part 14 is transitionally connected to the inner wall of the polygonal tube 13, and a driving part 15 is connected to the lower part of the movable part 14, and the driving part 15 is used to drive the movable part 14 to move in the vertical direction in the polygonal tube 13. When in use, the sides of the rectangular bottom plates 12 of the two casting mold monomers 1 that are away from the rectangular side plates 11 are attached to each other, so that a rectangular space opened at the front, back and top is enclosed between the two casting mold monomers 1.

[0032] In the above implementation manner, the formwork casting method of the PEC beam-column node casting device comprises the following steps:

[0033] Step 1: pre-open a hole 31 at a position of the floor slab 3 close to the PEC beam-column node, and the position of the hole 31 is opposite to the two holes 31 for subsequent pouring of concrete;

[0034] Step 2: The sides of the rectangular bottom plates 12 of the two casting mold monomers 1 that are away from the rectangular side plates 11 are attached to each other and fixed, so that a rectangular space that is open at the front, back and top is enclosed between the two casting mold monomers 1, and the two connected casting mold monomers 1 are positioned at one end of the I-beam of the PEC beam 5 close to the PEC column 4, so that the upper end of the multi-prism tube 13 is directly opposite to the opening 31, so that a closed casting space is formed between the two connected casting mold monomers 1 and the PEC beam-column node;

[0035] Step 3: The driving member 15 drives the movable member 14 to move downward, so that the opening 31 is connected to the casting space through the polygonal cylinder 13 and the opening 111;

[0036] Step 4: pouring concrete into the pouring space from the opening 31, so that the concrete fills the pouring space;

[0037] Step 5: Control the driving member 15 to drive the movable member 14 to move upward, so as to extrude the concrete in the polygonal cylinder 13 upward through the opening 31;

[0038] Step 6: Scrape the concrete at the opening 31, disassemble the two casting mold monomers 1, and complete the casting of the PEC beam-column node.

[0039] In the above embodiments, a PEC beam-column joint pouring device with a simple structure and low manufacturing cost is designed. The PEC beam-column joint pouring work can be achieved through simple pouring operations. After pouring, the excess concrete at the pouring hole can be extruded upward through the movable part 14 in the multi-faceted cylinder 13. On the one hand, it fills the pre-opened hole 31 of the floor slab 3, and there is no need for additional subsequent filling of the opening 111. On the other hand, compared with the traditional pouring method, there is no need to cut the concrete block left by the pouring hole subsequently, which greatly saves labor costs and working hours. Each pouring mold unit 1 is a plate-like structure, which can be welded by steel molds, has high structural strength, is not prone to deformation, is easy to load and unload, and can be reused.

[0040] As an alternative embodiment, the multi-faceted cylinder 13 is a quadrangular cylinder.

[0041] In the above embodiments, it is preferred that the multi-faceted cylinder 13 is a regular multi-faceted cylinder 13, which can improve the fluidity of concrete pouring and the smoothness of the operation of extruding excess concrete through the movable part 14.

[0042] As an alternative embodiment, the movable part 14 includes an upper movable plate 141 and a side movable plate 142 that are perpendicularly connected to each other. The shape of the upper movable plate 141 is a rectangle that is in transitional fit with the inner wall of the quadrangular cylinder. The side movable plate 142 is connected to the lower part of the side of the upper movable plate 141 facing the rectangular side plate 11, and the width of the side movable plate 142 is the same as the width of the upper movable plate 141.

[0043] In the above embodiments, on the one hand, the function of the movable part 14 is to extrude the excess concrete upward from above the multi-faceted cylinder 13 after pouring, which is achieved by the upper movable plate 141. On the other hand, it is necessary to flatten the concrete at the opening 111 to ensure the flatness of the concrete pouring at the opening 111 of the rectangular side plate 11, which is achieved by the side movable plate 142.

[0044] As an alternative embodiment, the shape of the opening 111 is rectangular, and the width of the opening 111 is the same as the width of the side where the multi-faceted cylinder 13 coincides with the rectangular side plate 11.

[0045] In the above embodiments, the design of the shape and width of the opening 111 can improve the fluidity of concrete pouring and ensure that the movable part 14 can completely push and discharge the excess concrete in the multi-faceted cylinder 13 upward.

[0046] As an alternative embodiment, the opening 111 is located at the upper part of the rectangular side plate 11, and the upper edge of the multi-faceted cylinder 13 is flush with the upper edge of the rectangular side plate 11.

[0047] In the above embodiments, more preferably, a convex edge may be further extended outward along the upper edge of the multi-faceted cylinder 13. During formwork installation, it can ensure that the upper edge of the multi-faceted cylinder 13 fits the lower edge of the opening 31 in the floor slab 3, so that when the movable member 14 pushes the excess concrete in the multi-faceted cylinder 13 upward and discharges it, it can accurately fill the pre-opening 31 of the floor slab 3.

[0048] As an alternative embodiment, the rectangular side plate 11 is provided with through holes 112 for passing the tie bolts 2.

[0049] In the above embodiments, in the formwork pouring method of the corresponding PEC beam-column joint pouring device, step 2 is specifically as follows: The sides of the rectangular bottom plates 12 of the two pouring mold units 1 facing away from the rectangular side plates 11 are mutually abutted and fixed, so that a cuboid space that is open in the front, rear, and upper directions is formed between the two pouring mold units 1. The two connected pouring mold units 1 are positioned at one end of the I-beam of the PEC beam 5 close to the PEC column 4, so that the upper end of the multi-faceted cylinder 13 is directly opposite to the opening 31. The tie bolts 2 are passed through the through holes 112 of the two pouring mold units 1 to assist in fixing the two rectangular side plates 11, so that a sealed pouring space is formed between the two connected pouring mold units 1 and the PEC beam-column joint.

[0050] As an alternative embodiment, the driving member 15 includes a vertical screw 151 and a nut 152. The upper end of the vertical screw 151 is rotatably connected to the lower part of the movable member 14. The vertical screw 151 is in threaded engagement with the nut 152, and the nut 152 is connected to the rectangular side plate 11 through a connecting member 153.

[0051] In the above embodiments, the driving member 15 adopts the form of a screw cooperating with the nut 152. By rotating the screw, the movable member 14 can be controlled to move up and down slowly and stably. Thus, by controlling the smooth upward movement of the movable member 14, the excess concrete can be stably extruded from above the multi-faceted cylinder 13.

[0052] As an alternative embodiment, a connecting plate 16 extends vertically downward from the side of the rectangular bottom plate 12 of the pouring mold unit 1 facing away from the rectangular side plate 11, and the connecting plate 16 is provided with a connecting hole 161.

[0053] In the above embodiments, a reinforcing rib 162 is connected between the connecting plate 16 and the rectangular bottom plate 12. By passing bolts through the two connecting holes 161, the two connecting plates 16 are mutually abutted and fixed, so as to realize the mutual abutment and fixation of the sides of the rectangular bottom plates 12 of the two pouring mold units 1 facing away from the rectangular side plates 11.

[0054] As an optional implementation, a circular cylinder 17 with its axial direction in the vertical direction is connected to the lower part of the rectangular bottom plate 12 of one of the casting mold units 1 .

[0055] In the above embodiments, the annular cylinder 17 is used to connect the support rod;

[0056] In the above-mentioned formwork casting method of the PEC beam-column node casting device, the step 2 is specifically as follows: the sides of the rectangular bottom plates 12 of the two casting mold monomers 1 that are away from the rectangular side plates 11 are attached to each other and fixed, so that a rectangular parallelepiped space open at the front, rear and top is formed between the two casting mold monomers 1, and the two connected casting mold monomers 1 are positioned at one end of the I-beam of the PEC beam 5 close to the PEC column 4, so that the upper end of the multi-faceted tube 13 is aligned with the opening 31, and the two casting mold monomers 1 are fixed to each other. A tension screw 2 is passed through the through hole 112 of the mold unit 1 to assist in fixing the two rectangular side panels 11, so that a closed casting space is formed between the two connected casting mold units 1 and the PEC beam-column node; the upper end of the support rod is inserted into the circular cylinder 17, and the lower end is supported and positioned on the lower floor slab 3. Preferably, the support rod can be designed with a length adjustment structure, and the length of the support rod can be adjusted by the length adjustment structure, so that the support rod is vertically and stably supported in the lower floor slab 3 and the circular cylinder 17.

[0057] As an optional implementation, the connecting member 153 is a supporting plate 1531 parallel to the rectangular bottom plate 12 .

[0058] In the above embodiment, as a preferred solution, vertical reinforcing plates 1532 can be designed on both sides of the support plate 1531, and a notch 1533 is provided at the upper end of the reinforcing plate 1532 close to one end of the rectangular side plate 11. Correspondingly, a limiting portion 1421 protruding outward is provided at the lower end of the side movable plate 142. The limiting portion 1421 is used to limit the extreme position of the upward and downward movement of the movable part 14. For example, when the movable part 14 moves upward, the limiting portion 1421 can be stuck on the lower edge of the polygonal cylinder 13 to limit its continued upward movement, and when the movable part 14 moves downward, the limiting portion 1421 can be stuck at the above-mentioned notch 1533 to limit its continued downward movement.
