In the main structure of a house, walls, columns, beams, and slabs are the main force-transmitting components. To ensure the force-transmitting effect and safety of the force-transmitting components, designers generally require the use of higher-strength concrete at the beam-column joints to meet the design concept of strong columns and weak beams. During the construction of concrete of different strength grades at the existing beam-column joints, the core node area and the surrounding areas cannot be poured at the same time, and isolation devices need to be used to separate them.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-4 In this embodiment, a concrete pouring isolation device with different strength grades at a beam-column joint includes a hollow support rod 1, an isolation mechanism is arranged on the outside of the hollow support rod 1, and a reinforcement component is arranged on the bottom of the hollow support rod 1.

[0025] Embodiment 1: The isolation mechanism includes a connecting seat 2 which is sleeved with a hollow support rod 1, and a mounting hole is opened inside the connecting seat 2. The connecting seat 2 is sleeved with the hollow support rod 1 through the mounting hole, which facilitates the connection between the connecting seat 2 and the hollow support rod 1, and is convenient for the user to disassemble and adjust the position of the connecting seat 2. A threaded pull rod 3 is inserted into the interior of the connecting seat 2, and a through hole 201 is opened inside the connecting seat 2. The threaded pull rod 3 is inserted into the connecting seat 2 through the through hole 201, which facilitates the connection between the threaded pull rod 3 and the connecting seat 2, and is convenient for the user to rotate the threaded pull rod 3 for adjustment, and is convenient for installing and disassembling the connecting seat 2. A telescopic spring 4 is sleeved on the outside of the threaded pull rod 3, and the external thread of the threaded pull rod 3 is connected to a movable plate 5 fixedly connected to the telescopic spring 4.

[0026] Among them, a threaded hole 501 is provided inside the movable plate 5, and the threaded pull rod 3 is threadedly connected to the movable plate 5 through the threaded hole 501, which is convenient for the connection between the threaded pull rod 3 and the movable plate 5. The movable plate 5 moves, driving the threaded pull rod 3 to move, which is convenient for limiting and fixing the connecting seat 2. The left and right sides of the movable plate 5 are fixedly connected with sliders 6 that are slidably connected to the connecting seat 2. Two sliding grooves are provided inside the connecting seat 2. The slider 6 is slidably connected to the connecting seat 2 through the sliding groove, which limits the movable plate 5 so that the movable plate 5 does not rotate with the threaded pull rod 3, which is convenient for the up and down movement of the movable plate 5. The bottom end of the threaded pull rod 3 is fixedly connected to the limiting block 7, and the top end of the threaded pull rod 3 is fixedly connected to the rotating wheel 8.

[0027] In addition, the bottom of the connecting seat 2 is fixedly connected to the isolation steel plate body 9, and the interior of the hollow support rod 1 is provided with a number of through grooves 101. The threaded pull rod 3 and the limit block 7 extend to the interior of the hollow support rod 1 through the through grooves 101, which is convenient for limiting the connecting seat 2 and reducing the sliding and deviation of the connecting seat 2 and the isolation steel plate body 9. The telescopic spring 4 is reset to push the movable plate 5 to move downward. The movable plate 5 drives the threaded pull rod 3 and the limit block 7 to move downward, so that the threaded pull rod 3 and the limit block 7 extend to the interior of the hollow support rod 1, and then, the threaded pull rod 3 is rotated to adjust the angle of the limit block 7 so that the limit block 7 is engaged with the hollow support rod 1 to complete the installation and fixation of the connecting seat 2 and the isolation steel plate body 9.

[0028] It should be noted that by setting up an isolation mechanism, the isolation steel plate is limited and fixed, which reduces the sliding deviation of the isolation steel plate during use, improves the isolation effect of the isolation device on concrete of different strengths, and solves the problem that the isolation steel plate is limited only near the two ends of the circular support rod, which may easily cause the isolation steel plate to slide and deviate during the use of the isolation device, affecting the isolation effect of the isolation device on concrete of different strengths.

[0029] Specifically, when using the isolation device to isolate concrete of different strength grades at the column node, the two ends of the hollow support rod 1 are fixed to the steel bars, and the isolation steel plate body 9 is placed on the pouring interface of concrete of different strength grades to isolate the concrete of different strength grades. During the pouring process, due to the clamping connection between the limit block 7 and the hollow support rod 1, the connecting seat 2 and the isolation steel plate body 9 are limited and fixed, thereby reducing the sliding deviation caused by the concrete squeezing the isolation steel plate body 9, thereby achieving the purpose of increasing the stability of the isolation steel plate, reducing the sliding deviation of the isolation steel plate, and facilitating the isolation device to isolate the pouring of concrete of different strengths.

[0030] Example 2: Please refer to Figure 1 and Figure 3 The reinforcement component includes a circular support shaft 10 fixedly connected to the isolation steel plate body 9, a wire brush 11 is fixedly connected to the outside of the circular support shaft 10, and a fixing screw 12 is connected to the internal thread of the circular support shaft 10. The circular support shaft 10 is fixedly connected to the isolation steel plate body 9 through the fixing screw 12, which facilitates the connection between the circular support shaft 10 and the isolation steel plate body 9. The wire brushes 11 on the outside of the circular support shaft 10 are distributed in a fan shape, and the mixing of concrete of different strengths is reduced by the wire brushes 11.

[0031] It should be noted that by providing a reinforcement component, the isolation effect of the isolation device on concrete of different strengths is increased, and the mixing of concrete of different strengths is reduced.

[0032] Specifically, when the isolation device is used to isolate concrete of different strength grades at the column joint, the wire brush 11 fills the pouring interface of concrete of different strength grades to reduce the mixing of concrete of different strengths during the pouring process.

[0033] The working principle of the above embodiment is:

[0034] (1) The isolation device for casting concrete of different strength grades at the beam-column joint, when using the isolation device to isolate concrete of different strength grades at the column joint, fix the two ends of the hollow support rod 1 to the steel bars, and place the isolation steel plate body 9 on the interface of the concrete casting of different strength grades to isolate the concrete of different strength grades. During the casting process, due to the clamping connection between the limit block 7 and the hollow support rod 1, the connecting seat 2 and the isolation steel plate body 9 are limited and fixed, reducing the sliding deviation caused by the concrete squeezing the isolation steel plate body 9, thereby achieving the purpose of increasing the stability of the isolation steel plate, reducing the sliding deviation of the isolation steel plate, and facilitating the isolation device to isolate the casting of concrete of different strengths.

[0035] (2) The isolation device for pouring concrete of different strength grades at the beam-column joint. When the isolation device is used to isolate concrete of different strength grades at the column joint, the wire brush 11 fills the pouring interface of concrete of different strength grades to reduce the mixing of concrete of different strengths during the pouring process.
