Description

Technical Field

[0001] This invention relates to an isolation device and method suitable for distinguishing concrete of different strengths at beam-column joints. Background Technology

[0002] When the concrete strengths of beams and columns are different, they need to be poured in two stages, first the column and then the beam. However, due to the dense reinforcement, complex joints, and small construction space at the beam-column junction, it is not easy to carry out construction operations. The problem of setting up barriers of different strength concrete at the beam-column junction is a difficult technical problem to solve.

[0003] Currently, steel wire mesh is used for enclosure on site. However, due to the limited construction space, it is difficult to install the steel wire mesh properly. A large amount of concrete slurry flows into the beam from the gaps on the side and bottom of the beam, resulting in a large color difference at the bottom of the beam and increasing construction costs. Summary of the Invention

[0004] The purpose of this invention is to provide an isolation device and method suitable for distinguishing concrete of different strengths at beam-column joints.

[0005] To address the above problems, the present invention provides an isolation device suitable for distinguishing concrete of different strengths at beam-column joints, comprising:

[0006] angle iron;

[0007] Multiple isolation bars, one end of each isolation bar is connected to an angle iron, and the isolation bars can rotate along the axis of the isolation bar;

[0008] Comb teeth, with multiple comb teeth vertically spaced on each isolation bar;

[0009] A polymer mesh is disposed on the beam-column joint, and the polymer mesh is formed on the surface of the isolation rod and the comb teeth.

[0010] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the polymer material mesh is a polycaprolactone polymer material.

[0011] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the isolation rod and comb teeth are inserted into the beam-column joint.

[0012] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, one end of each isolation rod rotates 90 degrees around the axis of the isolation rod, so that each comb tooth on the isolation rod rotates 90 degrees, and then each isolation rod and each comb tooth is combined to form a grid-like planar network.

[0013] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the polymer material mesh is formed on the grid-shaped planar mesh.

[0014] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the thickness of the polymer mesh is greater than the thickness of the grid-shaped planar mesh.

[0015] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the grid-shaped planar mesh is obliquely inserted into the end of the beam at the beam-column joint.

[0016] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, the number of isolation rods and comb teeth is determined according to the width of the beam.

[0017] Furthermore, in the aforementioned isolation device applicable to distinguishing concrete of different strengths at beam-column joints, a handle is connected to the angle iron.

[0018] According to another aspect of the present invention, an isolation method is also provided that employs the isolation device described in any one of the preceding claims for distinguishing concrete of different strengths at beam-column joints, the method comprising:

[0019] Adjust the number and spacing of the isolation rods and comb teeth according to the width of the beam at the beam-column joint;

[0020] After the isolation rod and comb teeth are inserted obliquely into the end of the beam at the beam-column joint, one end of the isolation rod is rotated 90 degrees around the axis of the isolation rod so that each comb tooth on the isolation rod rotates. Then, each isolation rod and each comb tooth is combined to form a grid-like planar network.

[0021] A polymer material is sprayed onto a grid-shaped planar mesh to form a polymer material network;

[0022] Once the polymer mesh meets the required strength, rotate one end of each isolation rod by -90 degrees relative to the angle iron, and then pull out the isolation rod and comb teeth from the end of the beam.

[0023] Compared with existing technologies, this invention includes: angle iron, isolation rods, comb teeth, and a polymer material mesh. The angle iron has evenly spaced holes. The isolation rods can be fixed to the holes in the angle iron using nuts or rivets, and can rotate along their axis. The isolation rods have evenly spaced comb teeth. After rotation, the comb teeth and the isolation rods form a grid-like planar mesh. Then, a polymer material is sprayed onto the grid-like planar mesh. The dense grid-like planar mesh facilitates the rapid formation of polycaprolactone. After the polycaprolactone hardens upon contact with air, the comb teeth are rotated back, and the isolation device is pulled out by holding the handle. At this point, the polymer material mesh, either flat or inclined, remains within the concrete component, functioning independently as an isolation mesh. This achieves the goal of blocking concrete on one side during pouring, thereby improving the pouring quality of concrete at beam-column joints with varying elevations. Furthermore, this isolation mesh has a simple structure and is convenient, fast, and effective to operate. Attached Figure Description

[0026] Figure 3 This is an installation schematic diagram of an isolation device according to an embodiment of the present invention, suitable for distinguishing concrete of different strengths at beam-column joints. Detailed Implementation

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown, the present invention provides an isolation device suitable for distinguishing concrete of different strengths at beam-column joints, comprising:

[0029] Angle iron 2;

[0030] Multiple isolation rods 3, one end of each isolation rod 3 is connected to angle iron 2, and the isolation rod 3 can rotate along the axis of the isolation rod;

[0031] Comb teeth 5, each isolation rod 3 has multiple comb teeth 5 vertically spaced;

[0032] The polymer material mesh 4 is disposed on the beam-column joint, and the polymer material mesh 4 is formed on the surface of the isolation rod 3 and the comb teeth 5.

[0033] Here, different grades of concrete can be poured on both sides of the polymer material mesh 4 of the present invention, which can provide a quick-installing, reusable isolation mesh for beam-column joints with different grades of concrete, and is used to distinguish concrete of different strengths at beam-column joints.

[0034] This invention includes angle iron, a separator rod, comb teeth, and a polymer mesh. The angle iron has evenly spaced holes. The separator rod can be fixed to the holes in the angle iron with nuts or rivets, and can rotate along its axis. The separator rod has evenly spaced comb teeth. After rotation, the comb teeth and the separator rod form a grid-like planar mesh. Then, a polymer material is sprayed onto the grid-like planar mesh. The dense grid-like planar mesh facilitates the rapid formation of polycaprolactone (PVC). After the PVC hardens upon contact with air, the comb teeth are rotated back, and the separator is pulled out by holding the handle. At this point, the planar or inclined surface of the polymer mesh remains within the concrete component, functioning independently as a separator. This achieves the goal of blocking one side of the concrete during pouring, thereby improving the pouring quality of concrete at beam-column joints with varying elevations. Furthermore, this separator has a simple structure and is convenient, fast, and effective to operate.

Moreover, this isolation mesh is simple to operate and easy to use.

[0044] In one embodiment of the isolation device of the present invention for distinguishing concrete of different strengths at beam-column joints, the number of isolation rods and comb teeth is determined according to the width of beam 6.

[0045] Here, the spacing of the polymer material isolation net of the present invention can be flexibly adjusted to adapt to various concrete components, such as: adjustable angle iron hole spacing and number of holes for installing different numbers of isolation rods, adjustable isolation rod length, adjustable comb tooth spacing and length on the isolation rods, etc., which can be applied to beam molds of various sizes and has a high turnover rate.

[0046] In one embodiment of the isolation device of the present invention for distinguishing concrete of different strengths at beam-column joints, the angle iron 2 is connected to a handle 1 to facilitate the insertion and removal of the isolation device.

[0047] According to another aspect of the invention, a consistent isolation method for distinguishing concrete of different strengths at beam-column joints is also provided, the method comprising:

[0048] Step S1: Adjust the number and spacing of the isolation rods 3 and comb teeth 5 according to the width of the beam at the beam-column joint;

Then, each isolation rod 3 and each comb tooth 5 are combined to form a grid-like planar network.

[0050] Step S3: Spray polymer material onto the grid-shaped planar mesh to form polymer material mesh 4;

[0051] Step S4: After the polymer material mesh 4 meets the strength requirements, rotate one end of each isolation rod 3 by -90 degrees relative to the angle iron 2, and then pull out the isolation rod 3 and comb teeth 5 from the end of the beam 6.
