DETAILED DESCRIPTION

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 6 As shown, a PEC beam-column post-cast node construction tool comprises a column body 1 and a structural beam 2 arranged on the column body 1, concrete 201 is cast on the structural beam 2, a prefabricated composite plate 202 is arranged on the concrete 201, a casting tool for easy casting is arranged at the junction of the structural beam 2 and the column body 1, the composite plate 202 is erected on the casting tool to form an integral structure, the casting tool comprises a formwork assembly 3 which is wrapped around the structural beam 2 and a detachable fixing assembly 4 for fastening the formwork assembly 3; the fixing assembly 4 comprises a clamping member 401 for clamping the formwork assembly 3 and a screw 402 for adjusting the clamping width of the clamping member 401 and tightening the clamping member 401; a casting port 3011 which is relatively arranged and used for casting is formed on the formwork assembly 3, and a precast hole 2021 corresponding to the casting port 3011 is provided on the composite plate 202.

[0030] Furthermore, the column 1 is vertically arranged, and the column 1 is a rectangular structure. The structural beam 2 is horizontally connected to the column 1. The structural beams 2 are connected to the four sides of the column 1. The two adjacent structural beams 2 are perpendicular to each other. Concrete 201 is poured on the structural beam 2, and a composite plate 202 is arranged above the concrete 201. When the joint between the structural beam 2 and the column 1, i.e. the node, is to be poured, holes for pouring are opened on the composite plate 202, and the concrete is poured to the node through the holes.

[0031] The formwork assembly 3 is wrapped around the structural beam 2, and the formwork assembly 3 is located at the junction of the structural beam 2 and the column 1. The top of the formwork assembly 3 abuts against the lower surface of the composite plate 202. The fixing assembly 4 is arranged on the formwork assembly 3, and the formwork assembly 3 is fastened to the structural beam 2 through the fixing assembly 4. With the cooperation of the formwork assembly 3 and the fixing assembly 4, when the PEC beam-column node is post-cast, there is no need to open a grouting hole on the upper part of the PEC beam, thereby reducing the structural impact on the PEC beam. While ensuring that the structure is not affected, the construction efficiency of the PEC beam-column post-cast node is improved.

[0032] In addition, since the fixing assembly 4 is a detachable structure and at least two groups of fixing assemblies 4 are arranged on the formwork assembly 3, the fixing assembly 4 can be removed and reused multiple times after the pouring is completed and the concrete is solidified, thereby saving resources and costs; at the same time, when the formwork assembly 3 is tightened, the clamping width of the clamping member 401 can be adjusted through the cooperation of the screw 402 and the clamping member 401, thereby meeting the pouring requirements of structural beams 2 of different sizes, improving the use range of the fixing assembly 4, and thereby improving the practicability of the pouring tooling.

[0033] The pouring ports 3011 opened on the formwork assembly 3 are located on opposite sides of the formwork assembly 3. When the formwork assembly 3 is fastened to the structural beam 2, the composite plate 202 is prefabricated in the factory, and corresponding holes are opened on the composite plate 202 at the same time. The positions of the holes correspond to the pouring ports 3011. Concrete enters the pouring ports 3011 through the holes and is then poured into the formwork assembly 3, thereby improving the pouring efficiency.

[0034] The formwork assembly 3 includes two relatively arranged plates 301, the two plates 301 are located on opposite sides of the structural beam 2, and the two plates 301 are abutted on the structural beam 2, and the two plates 301 and the structural beam 2 form a casting space. Furthermore, the plates 301 are made of wooden material, and the two plates 301 are tightly attached to the opposite sides of the structural beam 2. The bottom of the plates 301 is flush with the bottom of the structural beam 2, and the top of the plates 301 is abutted against the lower surface of the composite plate 202. The two plates 301 and the structural beam 2 and the composite plate 202 form a closed space, which is the casting space. Concrete is poured into the casting space through holes and casting ports 3011. The formed casting space can effectively ensure the tightness of the post-casting nodes to prevent leakage during casting.

[0035] The two pouring ports 3011 are both formed at the top of the corresponding plate 301, and the pouring ports 3011 are located at the side end of the plate 301. Furthermore, the top of the pouring port 3011 abuts against the lower surface of the composite plate 202. The pouring port 3011 is formed at the top edge of the plate 301, and the two pouring ports 3011 are relatively arranged. The pouring port 3011 is a funnel-shaped structure. By adopting a "funnel" device for the pouring port 3011 of the PEC beam-column post-cast node, the opening is larger than the opening on the traditional PEC beam, so the pouring efficiency is higher and the concrete is easier to compact. In addition, after maintenance, the tooling is removed and the excess concrete at the pouring port 3011 is chiseled out. Compared with traditional chiseling, the chiseled out concrete is smaller, which improves the convenience of construction.

[0036] Specifically, the pouring port 3011 is inclined toward the outside of the structural beam 2, that is, the inner side of the pouring port 3011 is an open structure connected to the pouring space, and the outer side of the pouring port 3011 is an inclined flat plate structure. The top of the pouring port 3011 is open, and concrete is poured into the pouring port 3011 from the top opening, and then flows into the pouring space.

[0037] To further explain, the bottom end of the pouring port 3011 is flush with the inner side of the plate 301, and the size of the pouring port 3011 gradually increases from bottom to top. The bottom of the pouring port 3011 is flush with the plate 301. During pouring, the flush setting can prevent concrete from accumulating at the bottom of the pouring port 3011. In addition, the size of the pouring port 3011 gradually increases from the bottom of the pouring port 3011 to the top of the pouring port 3011. During pouring, a large amount of concrete can enter the pouring port 3011, thereby improving the pouring efficiency. In addition, since the outer wall of the pouring port 3011 is inclined toward the outside of the structural beam 2, when the concrete enters the pouring port 3011, the inclined outer wall can make the concrete flow quickly, thereby avoiding the situation where the concrete flows too slowly and accumulates and blocks the pouring port 3011, thereby ensuring the smooth pouring.

[0038] In addition, it should be noted that a support plate 302 for supporting the pouring port 3011 is provided on the side wall of the pouring port 3011, a fixing block 303 for fixing the support plate 302 is provided on the plate 301, the fixing block 303 is fixedly arranged on the plate 301, the support plate 302 is vertically arranged on the upper side of the fixing block 303, and the top of the support plate 302 abuts against the inclined side wall of the pouring port 3011, and the support plate 302 is fixedly connected to the inclined side wall of the pouring port 3011. During pouring, as concrete continuously enters the The pouring port 3011 is in the pouring port 3011, thereby forming a great impact force on the pouring port 3011. As time goes by, the pouring port 3011 may be damaged and the concrete cannot enter the pouring space. Under the action of the fixing block 303 and the supporting plate 302, the pouring port 3011 is supported and fixed, ensuring that the inclined side wall of the pouring port 3011 can withstand the impact of the concrete and that the pouring port 3011 will not be damaged, thereby ensuring that the pouring is carried out smoothly and further improving the pouring efficiency.

[0039] At least two groups of fixing components 4 are arranged on the formwork component 3, and at least two groups of fixing components 4 are arranged along the length direction of the plate 301, and the distance between two adjacent fixing components 4 is the same. By setting at least two groups of fixing components 4, the plate 301 can be divided into several parts with the same spacing along the length direction, thereby ensuring the force balance of the plate 301, and further ensuring that the plate 301 can be firmly fastened to the side of the structural beam 2.

[0040] The clamping member 401 is a U-shaped structure, and the clamping member 401 is clamped on the structural beam 2 to fasten the plate 301. Furthermore, the clamping member 401 is a U-shaped structure with an open top. The clamping member 401 clamps from the bottom of the structural beam 2 to the opposite sides of the plate 301. The inner walls of the clamping member 401 are respectively abutted against the side walls of the corresponding plate 301. Under the action of the clamping member 401, the two plates 301 are fixed, ensuring that the plate 301 will not shake during pouring, thereby avoiding leakage of slurry.

[0041] Further explanation, when the clamping member 401 is clamped on the plate 301, the clamping member 401 is located on the outside of the two plates 301, and the clamping member 401 abuts against the plates 301, that is, the inner walls on both sides of the U-shaped structure of the clamping member 401 abut against the corresponding plates 301, ensuring that the plates 301 and the structural beam 2 are tightly fitted without leaving any gaps, thereby avoiding the penetration of concrete during the pouring process.

[0042] A connecting hole 4011 is formed on the clamping member 401, and the screw 402 passes through the connecting hole 4011 to be connected to the clamping member 401. Furthermore, the connecting hole 4011 is formed on the side wall of the clamping member 401, and the screw 402 is arranged in the connecting hole 4011, and when the clamping member 401 is clamped on the plate 301, the screw 402 is located below the plate 301.

[0043] Nuts 4022 for tightening the clamping member 401 are provided at both ends of the screw rod 402, and the nut 4022 is located on the outside of the clamping member 401. Furthermore, the nut 4022 is threadedly connected to the screw rod 402, and the nut 4022 is arranged on the opposite sides of the clamping member 401. A gasket 4021 sleeved on the screw rod 402 is arranged between the nut 4022 and the clamping member 401. When the clamping member 401 is clamped on the plate 301, the nut 4022 is rotated to shrink the clamping member 401, thereby shrinking the two sides of the clamping member 401, and then clamping the plate 301; when the clamping width of the clamping member 401 does not match the size of the structural beam 2, the position of the nut 4022 on the screw rod 402 is adjusted to achieve the adjustment of the clamping width of the clamping member 401, thereby meeting the use requirements of structural beams 2 of different sizes.

[0044] A construction method of a PEC beam-column post-casting node construction tool comprises the following steps:

[0045] S1, opening precast holes 2021 according to the casting positions on the composite board 202 prefabricated in the factory, and making the formwork assembly 3;

[0046] S2, placing two plates 301 on opposite sides of the structural beam 2, and ensuring that the pouring port 3011 corresponds to the precast hole 2021;

[0047] S3, rotating the nut 4022 to adjust the length of the screw rod 402 in the clamping member 401, thereby adjusting the clamping width of the clamping member 401, clamping the adjusted clamping member 401 on the plate 301, and then tightening the nut 4022 so that the clamping member 401 fixes the plate (301);

[0048] S4, pouring concrete onto the post-cast nodes of the PEC beams and columns through the pre-cast holes 2021 and the pouring ports 3011;
