Description

Technical Field

[0001] The utility model relates to the field of housing construction engineering, in particular to a device for separating concrete with different strengths at a plate-column joint. Background Art

[0002] In housing construction, the strength of column concrete during the main structure construction phase is typically higher than that of slab concrete. Currently, there are no effective methods or measures to ensure that column concrete is poured all the way to the top of the slab in one go. This results in the inclusion of low-strength slab concrete within the column height. This makes column concrete pouring difficult to ensure quality, does not meet the seismic requirements of strong columns and weak beams, and poses a safety hazard to the main structure during its design lifecycle. Utility Model Content

[0003] The utility model aims to provide a concrete separation device with different strengths at a plate-column joint, which can separate the concrete in the column from the plate concrete.

The bottom of the first flat steel is welded to the bottom surfaces of the square steels on both sides of the square steel notch, and the upper part of the first flat steel is welded to the side wall of the square steel via a transverse second flat steel. The upper end of the first flat steel exceeds the setting position of the second flat steel, and the second flat steel is filled with steel balls.

[0008] To optimize the above technical solutions, specific measures taken also include:

[0009] The first flat steel and the second flat steel on both sides of the square steel notch are symmetrically arranged, and the second flat steel on both sides of the square steel notch are filled with the same steel balls.

[0010] The two ends of the square steel are blocked and enclosed to form a concrete partition device, and adjacent square steels are buckled through connectors.

[0011] Furthermore, one end of the square steel is sealed by welding with a fourth flat steel, and the other end is sealed with a rubber plug. The fourth flat steel sealing ends of adjacent square steels are buckled at the rubber plug sealing locations of adjacent square steels through connectors.

[0012] The connecting piece comprises two adjacent slots, and the two slots are respectively used for inserting two square steels in different directions.

[0013] Furthermore, a hole is provided on the wall of the slot, and a flat-head self-tapping screw is screwed into the hole to fix the square steel in the slot.

[0014] As a preferred solution, a square concrete partition device is enclosed by four square steels, and adjacent square steels are perpendicular to each other.

[0015] Furthermore, the sealing position of the rubber plug on the square steel can be adjusted to accommodate column sections of different sizes.

The interior of the separation device is the high-strength column concrete poured in advance, and the exterior of the separation device is the low-strength slab concrete poured subsequently. The separation device can effectively prevent the low-strength slab concrete from flowing into the column, ensuring that the high-strength column concrete can be poured onto the slab surface at one time, solving the problem that the column concrete cannot be poured onto the slab surface, and ensuring the quality of the column concrete pouring.

[0020] The movable partition steel sheet is inserted upward from the notch of the square steel into the interior of the square steel. The interior of the square steel is filled with steel balls to reduce the installation resistance of the third flat steel at the upper end of the movable partition steel sheet.

[0033] The utility model provides a concrete separation device with different strengths for a plate-column joint, comprising a square steel 1, a movable separation steel sheet 7 and a steel ball 5. Figure 1 As shown, a plurality of square steels 1 are enclosed to form a concrete partition device;

[0034] like Figure 2 As shown, a full-length square steel notch 12 is opened at the bottom of the square steel 1, and first flat steels 3 perpendicular to the square steel notch 12 are welded on both sides of the square steel notch 12. The bottom of the first flat steel 3 is welded to the bottom surface of the square steel 1 on both sides of the square steel notch 12, and the upper part of the first flat steel 3 is welded to the side wall of the square steel 1 through the horizontal second flat steel 4; the upper end of the first flat steel 3 exceeds the setting position of the second flat steel 4, and the second flat steel 4 is filled with steel balls 5.

[0035] like Figure 3 As shown, the movable separation steel sheet 7 is inserted upward from the square steel notch 12 into the interior of the square steel 1 ; a transverse third flat steel 6 is welded to the top of the movable separation steel sheet 7 , and the third flat steel 6 is located between the steel ball 5 and the inner side of the top surface of the square steel 1 .

[0036] The steel ball 5 is a rotatable sphere and has a small contact area with the surrounding planar structures. Its shape and friction resistance contact surface can play a role in reducing resistance.

[0037] The two ends of the square steel 1 are blocked and enclosed to form a concrete partition device, and the adjacent square steels 1 are buckled together by connecting pieces 10, such as Figure 6 shown.

[0038] In some embodiments, a square concrete partition device is enclosed by four square steels 1 , and adjacent square steels 1 are perpendicular to each other.

[0039] The first flat steels 3 and the second flat steels 4 on both sides of the square steel notch 12 are symmetrically arranged, and the second flat steels 4 on both sides of the square steel notch 12 are filled with the same steel balls 5 .

[0040] In some embodiments, one end of the square steel 1 is welded and sealed with the fourth flat steel 2, and the other end is sealed with a rubber plug 8. The sealed ends of the fourth flat steels 2 of the adjacent square steels are buckled at the sealing places of the rubber plugs 8 of the adjacent square steels 1 through connectors, such as Figure 4 、 Figure 1 shown.

[0041] In some embodiments, the connector 10 includes two adjacent slots, and the two slots are respectively used to insert two square steels 1 in different directions.

[0042] A hole is provided on the wall of the slot, and a flat head self-tapping screw 11 is screwed into the hole to fix the square steel 1 in the slot.

[0043] In some embodiments, a punched circular hole 9 is provided on the wall of the movable partition steel sheet 7 for the plate reinforcement to pass through, such as Figure 5 shown.

[0044] In the solution of the present invention, the sealing position of the rubber plug 8 on the square steel 1 can be adjusted to adapt to column cross-sections of different sizes.

[0045] The following is further described in detail with reference to specific embodiments:

[0046] A device for separating concrete plates of different strengths at a column-plate joint comprises a square steel bar 1 having a length of column section plus 200 mm selected according to the column section size, a 4 mm wide slot being opened along the entire length of the lower portion of the square steel bar 1, one end of the square steel bar 1 being welded and sealed with a fourth flat steel bar 2, and the other end being sealed with a rubber plug 8 after a movable separation steel sheet 7 is installed.

[0047] The movable partition 7 of the device is arranged around the column (except the beam width) to prevent the column concrete from flowing into the plate outside the column.

[0048] Movable separation steel sheets 7 are made according to the spacing of the plate reinforcement bars. The movable separation steel sheets 7 are installed into the inside of the square steel 1 through the square steel notches 12 and sealed with rubber plugs 8 after installation. The vertical and horizontal square steels 1 around the column are fastened with connectors 10 and fixed with flat-head self-tapping screws 11, thereby forming a concrete separation device with different strengths for the plate and column. This device effectively blocks the low-strength concrete of the plate from flowing into the column, ensuring that the high-strength concrete of the column can be poured onto the plate surface at one time, solving the problem that the column concrete cannot be poured onto the plate surface and ensuring the quality of the column concrete pouring.

[0049] When the square steel 1 is installed in the frame beam, a beam width gap is reserved in the middle. No movable separating steel plate 7 is set at the beam width gap, that is, the movable separating plate 7 is set on both sides of the beam, and no movable separating plate is set within the beam width range, that is, this device does not divide the connection between the beam and the column concrete.

[0050] The square steel 1 is a rectangular square steel with a width of 30mm, a height of 50mm and a steel plate thickness of 2mm. The length is the column length or the column width + 200mm. The lower part is grooved with a length of 4mm. One end is sealed with a 2mm thick fourth flat steel 2, and the other end is sealed with a rubber plug 8 after the movable partition steel sheet 7 is installed.

[0051] The fourth flat steel 2 has a steel plate thickness of 2 mm, a width of 30 mm, and a height of 50 mm, and is used to seal one end of the square steel 1 .

[0052] The first flat steel 3 has a steel plate thickness of 2 mm, a height of 40 mm, and a length equal to the column length + 200 mm or the column width + 200 mm, and is welded to the square steel notch 12 by argon arc welding.

[0053] The second flat steel 4 is 2mm thick, 9mm wide, and has a length equal to the column length + 200mm or the column width + 200mm. It is welded to the first flat steel 3 and the inner wall of the square steel 1 using argon arc welding. The groove formed by welding the first and second flat steels 3 and 4 is used to accommodate φ10mm steel balls 5. The steel balls 5 fill the groove to reduce resistance during the installation of the movable partition steel plate 7.

[0054] The third flat steel 6 has a steel plate thickness of 2 mm, a width of 22 mm, and a length equal to the spacing between the plate reinforcements, and is welded to the movable separation steel sheet 7 by argon arc welding.

[0055] The thickness of the movable partition steel sheet 7 is 2mm, the width is the spacing between the plate reinforcements, and the length is the plate thickness + 40mm. It is welded to the third flat steel 6 by argon arc welding. The width of the movable partition steel sheet 7 needs to be determined according to the spacing between the plate reinforcements designed in the drawing, and can be made into widths of 150mm, 180mm, 200mm and other spacings.

[0056] The rubber plug 8 blocks the other end of the square steel 1 after the movable separating steel sheet 7 is installed according to the steel bar spacing designed in the drawing.

[0057] The punched circular hole 9 is φ20mm in size and is used for the plate reinforcement to pass through.

[0058] The connecting piece 10 is formed by welding two U-shaped slots, and is a connecting piece 10 in which 2 mm thick square steel 1 intersects vertically, and is formed by welding two U-shaped slots.

[0059] The flat head self-tapping screw 11 is of φ5mm and is used to fix the connecting piece 10 and the square steel 1 to ensure that the vertically intersecting square steels 1 do not slip.

[0060] The concrete separator is installed along the four sides of the column, which can ensure that the column concrete does not overflow and can be poured to the top of the slab at one time. After the column concrete is initially set, the connector 10 is removed and the square steel rod 1 is taken out, and the beam and slab concrete can be poured, thereby ensuring that the column concrete does not overflow and the slab concrete does not flow into the column, thereby achieving the effect of separating the concrete.

[0061] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modification, equivalent replacement and improvement made by any technician familiar with the profession to the above embodiments based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
