[0002] With the healthy development of the construction industry, the requirements for the pouring, molding and visual quality of concrete in the beam-column joint area are gradually increasing. Local mixing of high- and low-grade concrete can easily cause discontinuities or bubbles or gaps at the junction, resulting in the inability to completely fill the concrete, and causing cracks due to concrete shrinkage after molding.

[0003] At present, the on-site interception methods include wire mesh + welded steel bar head fixation, inflatable airbag separation, special steel plates, etc., but some problems still exist, resulting in difficulty in removing welding slag, loose airbag gaps, and poor visual quality of concrete after demolding.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0035] Embodiment: A device for separating concrete of different grades at beam-column joints, such as Figure 1 、 2 As shown, it includes an inflatable partition 1, several standard partitions 2 and two side partitions 3.

[0036] Among them, the inflatable partition 1 is assembled into an inverted T-shaped structure by welding six stainless steel plates, with a cavity 101 left inside. Both sides of the cavity 101 are provided with cavity baffles 102 that can move left and right. The top stainless steel plate is reserved with an inflation hole 103 that leads to the cavity 101. The bottom of the inflatable partition 1 is covered with a 3mm thick non-slip silicone plate, so that the inflatable partition 1 can be tightly and firmly connected to the bottom formwork of the beam; both sides of the inflatable partition 1 are densely covered with regularly arranged inflatable dividing rods 104, which are movably connected to the side of the inflatable partition 1 and fixedly connected to the cavity baffle 102. The inflatable dividing rods 104 are rubber rods with a diameter of 1.5mm and are arranged at intervals of 3mm.

[0037] Several standard partitions 2 are distributed on both sides of the inflatable partition 1. The standard partition 2 is made of stainless steel plate and has an inverted T-shaped structure. A standard handle 201 is provided on the top of the standard partition 2. The bottom of the standard partition 2 is covered with a 2mm thick non-slip silicone plate. Both sides of the standard partition 2 are densely covered with regularly arranged standard dividing rods 202. The standard dividing rods 202 are staggered with the inflatable dividing rods 104. The standard dividing rods 202 are rubber rods with a diameter of 1.5mm and are arranged at intervals of 3mm.

[0038] The two side partitions 3 are respectively placed on the two outer sides of the standard partition 2. The side partitions 3 are made of stainless steel plates in an L-shaped structure. A side handle 301 is provided on the top of the side partition 3. The bottom of the side partition 3 is covered with a 4mm thick non-slip silicone plate. The inner side of the side partition 3 is densely covered with regularly arranged side dividing rods 302. The side dividing rods 302 are staggered with the standard dividing rods 202. The side dividing rods 302 are rubber rods with a diameter of 1.5mm and are arranged at intervals of 3mm.

[0039] like Figure 3 As shown, the construction method of the partition device includes:

[0040] Carry out beam and column reinforcement binding and formwork installation according to the drawings, and determine the installation position of the partition device and the number of standard partitions 2;

[0041] Install the side partitions 3 on both sides of the beam formwork 4, press the side partitions 3 against the beam side formwork, and squeeze the anti-slip silicone plate at the bottom of the side partitions 3 to ensure that there is no gap between them and the beam formwork 4;

[0042] Install the standard partition 2 close to the side partition 3, and after avoiding the steel bars, insert the standard partition rod 202 tightly into the side partition rod 302, so that the side and bottom surfaces of the standard partition 2 and the side partition 3 are connected as a whole to form a certain strength and rigidity;

[0043] When the construction project is convenient and the beam cross-section is moderate, the standard partition 2 and the side partition 3 are directly used to form a whole to separate the space on both sides of the beam template 4;

[0044] When the beam section width is large and only using the standard partition 2 is difficult to ensure the effect, align the inflatable partition 1 with the standard partitions 2 on both sides and preliminarily fix them;

[0045] Install the air pump 5 and install the air tube 6 into the air hole 103;

[0046] Start the air pump 5 to inflate the cavity 101 of the inflatable partition 1, push the cavity baffle 102 to drive the inflatable partition rod 104 to move, so that it is tightly combined with the standard partition rods 202 on both sides;

[0047] Close the air filling hole 103 and pour high and low grade concrete on both sides of the beam-column joint in sequence;

[0048] After the concrete is poured, the air holes 103 are connected to pump air, and the cavity baffle 102 is pulled to drive the air-filled separator rods 104 to be retracted, so that they are separated from the standard separator rods 202 on both sides;

[0049] After separation is completed, remove the air pump 5;

[0050] After removing the inflatable partition 1, remove the standard partition 2 in sequence, and finally remove the side partition 3;

[0051] When the inflatable partition 1 is not used, the standard partition 2 is directly removed in sequence, followed by the side partition 3;

[0052] The partition device is flushed and the residual concrete, mortar and other debris on the upper part are removed, and the construction is completed.

[0053] In this embodiment, the cross-connected, tightly interlocking divider bars provide the overall separator with a certain degree of strength and rigidity, effectively intercepting concrete on both sides. The separator is composed of multiple components, allowing for easy cleaning of residual concrete after use, facilitating subsequent use and installation. Furthermore, the separator effectively addresses the quality issues associated with pouring and forming high- and low-grade concrete at beam-column joints, reducing the difficulty of separator installation prior to pouring and facilitating post-pour disassembly.

[0054] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent replacements made using the description and drawings of the present invention, directly or indirectly applied in other related technical fields, are also within the patent protection scope of the present invention.
