[0028] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Reference Figures 1 to 7 As shown, the present invention provides a rotatable and easily dismantled dividing bar device, comprising: a hard isolating member 1 and a dividing bar assembly 2.

[0031] Among them, see Figure 1 As shown, the hard spacer 1 is in a grid shape. The hard spacer 1 is formed with a receiving groove 10, and the cross section of the receiving groove 10 is in an inverted trapezoidal shape.

[0032] The partition bar assembly 2 is detachably embedded in the receiving groove 10 .

[0033] Specifically, the spacer bar assembly 2 includes a plurality of pipe sections 21 and a plurality of connectors 22 .

[0034] The connector 22 is in a cross shape, a straight shape, a T shape or an L shape.

[0035] Multiple pipe sections and multiple connectors are spliced ​​together to form a grid shape. Figure 2 As shown, the shape and size of the cross section of the pipe section 21 are adapted to the shape and size of the cross section of the receiving groove 10 .

[0036] The pipe section 21 has an upper wide side and a lower narrow side opposite to each other. Two oblique waist sides are connected between the upper wide side of the pipe section 21 and the lower narrow side of the pipe section 21. The upper wide side of the pipe section 21 is provided with a hook hole.

[0037] The connector has at least two ends. At least two ends of the connector 22 are respectively formed with plug connectors 221. The plug connector 221 is detachably inserted into the pipe opening of the pipe section 21. The outer diameter of the connector 22 is adapted to the outer diameter of the pipe section 21.

[0038] As a preferred embodiment, the thickness of the hard isolating member 1 is 0.1 mm. The wall of the accommodating groove 10 is adsorbed on the dividing bar assembly 2 by water.

[0039] In this embodiment, the hard spacer 1 is a hard plastic spacer.

[0040] See also Figures 3 to 6 As shown, the outer wall of the plug connector 221 is formed with a convex point 222. The plug connector 221 is interference-fitted with the pipe opening of the pipe section 21 through the convex point 222.

[0041] In this embodiment, the pipe section is a trapezoidal cross-section stainless steel pipe with a length modulus of 2m or 3m. The length of the upper bottom of the cross section is 20mm, the length of the lower bottom is 15mm, and the height is 30mm. The isosceles trapezoidal cross section is conducive to the complete removal of the separator assembly, and will not damage the concrete, resulting in missing edges and corners of the separation joint. The top surface of the pipe section (i.e., the upper wide side) is provided with 20mm×5mm hook holes at intervals of one meter, which are used in conjunction with the pull hook during removal.

[0042] The hard spacer is made of a hard plastic film. The thickness of the plastic film is 0.1mm, slightly thicker than a standard A4 paper of 70g, and is pressed into an isosceles trapezoid that is consistent with the cross-section of the separator assembly. When in use, first wet the outer surface of the separator assembly, and then use the surface tension of water to gently fit the hard spacer to the bottom and both sides of the separator. When removed, the hard spacer and the separator assembly will fall off naturally.

[0043] The connector is made of a stainless steel trapezoidal tube. The cross-sectional size of the connector end is reduced by 2mm and a convex point is set to clamp the pipe section. The connector is divided into four different shapes: "+", "L", "T", and "-", which are used to connect pipe sections in different parts and play the role of connection and overall fixation.

[0044] In addition, when in use, mortar needs to be placed under the hard isolation piece to make the top surface of the dividing strip device flush with the elevation of the concrete living surface, to assist in controlling the elevation and flatness of the living surface.

[0045] The pull hook cooperates with the hook hole at the top of the separator bar assembly, and the separator bar assembly is gently pulled out.

[0046] The rotatable and easily removable dividing strip device of the present invention achieves the purpose of easy removal, rotatability, straight and complete dividing seams, and high surface flatness by setting the dividing strip cross-section as a trapezoidal structure that is wide at the top and narrow at the bottom, arranging a hard isolation piece at the bottom, and setting a hook hole at the top, and fixing the whole device with connectors of different shapes.

[0047] The rotatable and easily dismantled dividing strip device of the present invention is used for setting dividing strips in concrete construction of roofs, floors and other parts, and can efficiently and conveniently reserve dividing strips. Moreover, due to the high rigidity of the (stainless steel) dividing strip assembly, the survival quality of the dividing strips and the surface layer is higher than that of traditional practices, which reduces rework and repairs and achieves one-time excellence. The device can be widely used in concrete roof and floor construction and is popularizable.

[0048] The present invention provides a construction method for a rotatable and easily dismantled separator strip device, which is characterized by comprising the following steps:

[0049] S1. Lay mortar on the construction position along the dividing joint on the working surface to form a cushion layer.

[0050] S2, embedding the partition bar assembly 2 into the receiving groove 10 of the hard isolation component 1.

[0051] S3. Place the hard isolation member 1 embedded with the partition bar assembly 2 on the cushion layer, so that the top surface elevation of the partition bar assembly 2 is adapted to the top surface elevation of the three layers of concrete to be poured.

[0052] S4, pouring concrete 3 on the working surface so that the hard isolation member 1 is buried in the liquid surface of the concrete 3.

[0053] S5. Provide a hook. After the concrete 3 solidifies, extend the hook into the pipe section 21 through the hook hole on the pipe section 21 of the dividing strip assembly 2 and hook the inner wall of the pipe section 21 to pull the dividing strip assembly 2 out of the accommodating groove 10, so that the dividing strip assembly 2 is separated from the hard isolation member 1.

[0054] The construction method of the recyclable and easily dismantled separator strip device of the present invention firstly arranges and calculates the length of the separator strip. The length modulus of the pipe segments of the separator strip assembly is set to 2m and 3m, and after combination, it can meet the use requirements of the separator strip spacing of 2 to 6 meters. Before use, the separator strip layout diagram is first drawn on the CAD to calculate the required amount of pipe segments.

[0055] After the separator assembly is assembled, the hard spacer is attached to the separator assembly. When using, first moisten the outer surface of the separator assembly with clean water, and then use the surface tension of water to gently attach the hard spacer to the bottom and both sides of the separator assembly. When removing, the hard spacer and the separator assembly will fall off naturally.

[0056] Next, according to the layout diagram of the partition seams, the pipe sections are connected with the help of four connectors, namely "+", "L", "T" and "-", to form a partition seam network combination and connect them into a whole.

[0057] After the mortar is used to pile up a triangular cross-section cushion, the assembled dividing strip device is placed on the cushion so that the top surface of the dividing strip device is flush with the concrete live surface elevation, further assisting in the control of the live surface elevation and flatness. During concrete construction, the surface is closed to the top elevation of the dividing strip device.

[0058] After the concrete solidifies, remove the separator assembly. Use a hook to hook the hook hole on the top of the pipe section or connector, and gently pull out the pipe section from one end. At this time, the separator assembly and the hard isolation piece will fall off naturally, and the hard isolation piece will remain in the separation gap as a consumable.

[0059] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
