Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an anti-floating point reinforcement structure and a hollow floor slab. Background Art
[0002] The construction quality of hollow floor slab is a crucial part of the main project construction. The hollow floor slab is delivered with plain concrete, which has high requirements on the surface quality of concrete. Therefore, the reliability of the hollow floor core mold's anti-floating point and the surface quality after demoulding are crucial to the project quality.
[0003] The thickness of the hollow floor in this project ranges from 400 to 500 mm, and the core molds of the hollow floor are all 300 mm high. During the pouring of concrete, the buoyancy exerted by the concrete on the core mold of the hollow floor will be large, which will cause the core mold of the hollow floor to float up, so the core mold will be fixed on the steel bars above the lower template. However, due to the large buoyancy of the core mold, the steel bars fixed to the core mold will be subject to a large buoyancy and float up. Therefore, in order to prevent the displacement and floating of the core mold and the steel bars, corresponding anti-floating point design is required.
[0004] The main traditional anti-floating point measures are: locate the control points on the template according to the design requirements, drill holes with an electric drill, and use 14# iron wire to pass through the template and the horizontal steel pipe of the template support frame at the bottom of the template to fix the steel bars at the bottom of the floor panel to form an anti-floating point. The above traditional anti-floating point method of tying iron wire requires at least two workers to cooperate with each other to complete the operation, and the labor cost is relatively high.
[0005] Therefore, there is an urgent need for a new type of hollow floor anti-floating point reinforcement device that is simple to construct and efficient to solve the above problems. Utility Model Content

[0011] In one embodiment, the bending portion and the connecting portion are both made of polyethylene.
[0012] In one embodiment, the anti-floating point reinforcement structure includes two connecting parts, and the upper ends of the two connecting parts are respectively arranged on opposite sides of the bending part; the bending part includes a first plate segment, a second plate segment and an arc segment, one end of the arc segment is connected to the first side surface of the first plate segment, and the other end of the arc segment is connected to the first side surface of the second plate segment; the second side surface of the first plate segment is connected to the connecting part on one side, and the second side surface of the second plate segment is connected to the connecting part on the other side.
[0013] In one embodiment, the first plate segment extends along a first straight line direction, and the second plate segment extends along a second straight line direction, and both the first straight line direction and the second straight line direction are tangent to the arc direction of the arc segment; the length of the first plate segment in the first straight line direction and the length of the second plate segment in the second straight line direction are both 80 mm ± 1 mm.
[0014] In one embodiment, the thickness range of the first plate segment, the second plate segment and the arc segment is 1.5 mm±0.5 mm.
[0015] In one embodiment, the connecting portion is configured as a plate-like structure, a first side of the connecting portion is connected to the bending portion, a second side of the connecting portion is detachably connected to the building formwork, and the first side is opposite to the second side; the flatness range of the lower plate surface of the connecting portion is 0 mm to 0.5 mm; and the thickness range of the connecting portion is 3 mm ± 1 mm.
[0016] The utility model also proposes a hollow floor slab, which includes a core mold, floor slab steel bars, a building formwork and the above-mentioned anti-floating point reinforcement structure; the floor slab steel bars are arranged alternately in the horizontal direction and the longitudinal direction on a horizontal plane, and the alternately arranged floor slab steel bars intersect each other at the intersection; the floor slab steel bars are connected to the core mold; the plate surface of the building formwork is arranged horizontally, and the building formwork is located below the floor slab steel bars; the connecting part of the anti-floating point reinforcement structure is detachably connected to the top of the building formwork, so that the bent part of the anti-floating point reinforcement structure abuts against the intersection of the floor slab steel bars and presses the floor slab steel bars onto the building formwork.

During the pouring process, since the concrete will generate buoyancy on the core formwork, the core formwork and the steel bars connected to the core formwork will float up under the action of buoyancy; and the anti-floating point reinforcement structure is adopted to fix the floor steel bar and realize the anti-floating of the core formwork and the floor steel bar. The traditional method of tying iron wire to prevent floating requires drilling holes in the building formwork and inserting iron wires on the upper and lower sides of the building formwork to tie and fix the floor slab steel bars to the steel pipes of the formwork frame located below the building floor slab; this construction process requires at least two operators to perform drilling and tying iron wires above and below the formwork, respectively, and the drilling points are sometimes inaccurate during the drilling process and may need to be re-drilled, which is not very accurate, further increasing the workload of anti-floating point construction. However, this anti-floating point reinforcement structure only needs to place the bent part on the floor slab steel bars and allow the connecting part to be detachably connected to the building formwork, so that the floor slab steel bars can be pressed onto the building formwork, eliminating the operations of drilling holes and tying iron wires, reducing the workload, and in the actual anti-floating point construction process, only one operator is required to complete all operations, reducing the labor cost required for anti-floating point construction, so this anti-floating point reinforcement structure has a higher economic benefit.

[0027] The construction quality of hollow floor slab is a crucial part of the main project construction. The hollow floor slab is delivered with plain concrete, which has high requirements on the surface quality of concrete. Therefore, the reliability of the hollow floor core mold's anti-floating point and the surface quality after demoulding are crucial to the project quality.
[0028] The thickness of the hollow floor in this project ranges from 400 to 500 mm, and the core molds of the hollow floor are all 300 mm high. During the pouring of concrete, the core mold of the hollow floor will float up due to the large buoyancy of the concrete on the core mold of the hollow floor, so the core mold will be fixed on the steel bars above the lower template. However, due to the large buoyancy of the core mold, the steel bars fixed to the core mold will be subject to a large buoyancy and float up. Therefore, in order to prevent the displacement and floating of the core mold and the steel bars, corresponding anti-floating point design is required.
[0029] The main traditional anti-floating point measures are: locate the control points on the template according to the design requirements, drill holes with an electric drill, and use 14# iron wire to pass through the template and the horizontal steel pipe of the template support frame at the bottom of the template to fix the steel bars at the bottom of the floor panel to form an anti-floating point. The above traditional anti-floating point method of tying iron wire requires at least two workers to cooperate with each other to complete the operation, and the labor cost is relatively high.
[0030] In order to solve the above problems, the utility model provides the following technical solutions.
[0031] The utility model provides an anti-floating point reinforcement structure.
[0032] See also Figure 1 and 2 In one embodiment of the utility model, the anti-floating point reinforcement structure is applied to the building formwork of the hollow floor, and a floor steel bar is arranged above the building formwork. The anti-floating point reinforcement structure includes a bending portion 1 and a connecting portion 2; the upper ends of the connecting portion 2 are respectively arranged on the opposite sides of the bending portion 1, and there is a preset distance between the lower ends of the bending portion 1 and the connecting portion 2 in the vertical direction; the connecting portion 2 is used to connect with the top of the building formwork, so that the bending portion 1 abuts against the floor steel bar and presses the floor steel bar onto the building formwork.
[0033] The utility model is connected to the building formwork through the connection part 2 of the anti-floating point reinforcement structure, and the bending part 1 of the anti-floating point reinforcement structure presses the floor steel bar on the building formwork, so as to realize the mutual fixation of the floor steel bar and the building formwork. During the pouring process, since the concrete will generate buoyancy on the core mold, the core mold and the steel bars connected to the core mold will float up under the action of buoyancy; and the anti-floating point reinforcement structure is adopted to fix the floor steel bar and realize the anti-floating of the core mold and the floor steel bar. The traditional anti-floating method of tying iron wire requires drilling holes on the building formwork and passing the iron wire through the upper and lower sides of the building formwork to tie and fix the floor steel bar with the steel pipe of the formwork frame located under the building floor. The construction process requires at least two operators to perform drilling and tying iron wire operations above and below the formwork respectively, and the drilling points may sometimes be inaccurate during the drilling process, and may need to be re-drilled, and the accuracy is not high, which further increases the workload of anti-floating point construction. The anti-floating point reinforcement structure only needs to place the bending portion 1 on the floor slab steel bars and allow the connecting portion 2 to be detachably connected to the building formwork, so that the floor slab steel bars can be pressed onto the building formwork, eliminating the operations of punching holes and tying wires, reducing the workload, and in the actual anti-floating point construction process, only one operator is required to complete all operations, reducing the labor cost required for the anti-floating point construction. Therefore, the anti-floating point reinforcement structure has higher economic benefits.
[0034] In addition, after the concrete is poured and formed, it is necessary to remove the formwork. During the demolding process, the steel pipes of the formwork frame under the building formwork need to be removed, and the building formwork needs to be removed. In the traditional anti-floating point method, iron wire is used to tie and fix the floor slab steel bars and the steel pipes of the formwork frame, so all the iron wires need to be cut during the demolding process. After the concrete is formed, part of the iron wire remains inside the formed concrete, and part of the iron wire is exposed on the concrete surface. Each iron wire exposed on the concrete surface needs to be cut off, and the concrete surface with the remaining iron wire is polished with a grinder to make the concrete surface flat. After adopting the anti-floating point reinforcement structure of the utility model, after the concrete is formed, the main part of the connecting part 2 and the bending part 1 are left inside the concrete, and only the bottom surface of the connecting part 2 is exposed on the concrete surface. Since the bottom surface of the connecting part 2 is relatively flat, it is not necessary to polish the surrounding area of the concrete where the bottom surface of the connecting part 2 is exposed, which not only reduces the workload during the demolding process, but also ensures the apparent quality of the concrete surface.
[0035] In the above embodiment, the detachable connection between the connection part 2 of the anti-floating point reinforcement structure and the building template has multiple optional connection modes. Figure 2As an optional embodiment, the anti-floating point reinforcement structure also includes a threaded fastener; a connecting through hole 21 is provided on the connecting portion 2, and the threaded fastener passes through the connecting through hole 21 and is threadedly connected to the building formwork. The threaded connection method is simple to process and has reliable connection, and is suitable for the detachable connection between the anti-floating point reinforcement structure and the building formwork. Furthermore, as an optional embodiment, the threaded fastener can be set as a self-tapping screw. In this way, there is no need to open a screw hole on the building formwork and then lock the threaded fastener into the screw hole. The self-tapping screw can be directly locked to the building formwork using an electric drill or other equipment, and the threaded connection is completed while drilling, saving the operating workload. The self-tapping screw in this embodiment can be set as an M4×20 high-strength cross self-tapping screw. Of course, the user can also choose self-tapping screws of other specifications according to actual construction requirements. The specifications of the self-tapping screws are not limited here.
[0036] See also Figure 1 and 2 In the embodiment of the utility model, the anti-floating point reinforcement structure includes two connecting parts 2, and the upper ends of the two connecting parts 2 are respectively arranged on opposite sides of the bending part 1; the shortest straight line direction from one connecting part 2 to another connecting part 2 is the first direction, the second direction is perpendicular to the first direction, and the second direction and the first direction are both horizontal directions. In this embodiment, the size reference values of the bending part 1 and the connecting part 2 in one case are given. The case is as follows: the thickness range of the hollow floor is 400mm to 500mm, and the core molds of the hollow floor are all 300mm high core molds. In this case, the length of the bending part 1 along the second direction and the length of the connecting part 2 along the second direction are set to 20mm±1mm, and the length of the connecting part 2 along the first direction is 10mm±1mm. The design of each dimension of the bending part 1 and the connecting part 2 has been verified by formulas and actual engineering verification, and can meet the anti-floating point design requirements. Of course, there is no restriction on the optional dimensions of the bending part 1 and the connecting part 2, and the actual size can be adjusted accordingly according to different anti-floating point design requirements.
[0037] In addition, after demolding, since the bottom surface of the connecting portion 2 will expose the lower surface of the formed concrete, if the connecting portion 2 is made of metal material, it is easy to affect the apparent quality of the concrete after rusting. In the embodiment of the utility model, in order to solve the problem that the exposed connecting portion 2 affects the apparent quality of the concrete, the material of the bending portion 1 and the connecting portion 2 is set to polyethylene material. Polyethylene (PE) is a thermoplastic resin with good chemical stability and a certain tensile strength. It is used as the material of the bending portion 1 and the connecting portion 2, which can ensure that the anti-floating point reinforcement device can provide sufficient anti-floating effect while ensuring that the connecting portion 2 exposed on the concrete surface can remain stable for a long time to avoid affecting the apparent quality of the concrete. In addition, since the appearance of the polyethylene material is milky white, and the color of the clear water concrete after forming or stabilization is whitish, the appearance color of the bending portion 1 and the connecting portion 2 made of polyethylene material is close to that of the clear water concrete. After the concrete is formed, there is no need to do additional oil brush painting on the bottom surface of the connecting portion 2, which saves workload.
[0038] See also Figure 1 In the embodiment of the utility model, the anti-floating point reinforcement structure includes two connecting parts 2, the upper ends of the two connecting parts 2 are respectively arranged on the opposite sides of the bending part 1; the bending part 1 includes a first plate segment 11, a second plate segment 12 and an arc segment 13, one end of the arc segment 13 is connected to the first side of the first plate segment 11, and the other end of the arc segment 13 is connected to the first side of the second plate segment 12; the second side of the first plate segment 11 is connected to the connecting part 2 on one side, and the second side of the second plate segment 12 is connected to the connecting part 2 on the other side. Specifically, as an optional embodiment, the first plate segment 11, the second plate segment 12 and the arc segment 13 are integrally formed.
[0039] In the embodiment of the utility model, the first plate segment 11 extends along the first straight line direction, and the second plate segment 12 extends along the second straight line direction, and the first straight line direction and the second straight line direction are both tangent to the arc direction of the arc segment 13. This embodiment provides the size reference values of the bending portion 1 and the connecting portion 2 under one situation. The situation is as follows: the thickness range of the hollow floor is 400mm to 500mm, and the core mold of the hollow floor adopts a 300mm high core mold. In this case, the length of the first plate segment 11 in the first straight line direction and the length of the second plate segment 12 in the second straight line direction are both 80mm±1mm. The thickness range of the first plate segment 11, the second plate segment 12 and the arc segment 13 is 1.5mm±0.5mm. The above-mentioned dimensional designs of the bending portion 1 and the connecting portion 2 have been verified by formulas and actual engineering verifications, and can meet the anti-floating point design requirements. Of course, there is no restriction on the optional sizes of the bending portion 1 and the connecting portion 2, and the actual size can be adjusted accordingly according to different anti-floating point design requirements.
[0040] See also Figure 1 and 2 In the embodiment of the utility model, the connecting part 2 is set as a plate-like structure, the first side of the connecting part 2 is connected to the bending part 1, the second side of the connecting part 2 is detachably connected to the building template, the first side is opposite to the second side, and the flatness range of the lower plate surface of the connecting part 2 is 0mm to 0.5mm. In this way, the lower plate surface of the connecting part 2 is relatively flat, which is convenient for the connection between the connecting part 2 and the building template. This embodiment gives the size reference values of the bending part 1 and the connecting part 2 in one case. The situation is as follows: the thickness range of the hollow floor is 400mm to 500mm, and the core molds of the hollow floor all use 300mm high core molds. In this case, the thickness range of the connecting part 2 is 3mm±1mm. The above-mentioned dimensional designs of the bending part 1 and the connecting part 2 have been verified by formulas and actual engineering verifications, and can meet the anti-floating point design requirements. Of course, there is no restriction on the optional sizes of the bending part 1 and the connecting part 2, and the actual size can be adjusted accordingly according to different anti-floating point design requirements.
[0041] The utility model also proposes a hollow floor, which includes a core mold, floor steel bars, a building formwork and the above-mentioned anti-floating point reinforcement structure; the floor steel bars are arranged in a staggered manner in the horizontal direction and the vertical direction on the horizontal plane, and the staggered floor steel bars intersect each other at the intersection; the floor steel bars are connected to the core mold; the board surface of the building formwork is arranged horizontally, and the building formwork is located below the floor steel bars; the connecting part 2 of the anti-floating point reinforcement structure is detachably connected to the top of the building formwork, so that the bending part 1 of the anti-floating point reinforcement structure abuts against the intersection of the floor steel bars and presses the floor steel bars onto the building formwork. The specific structure of the anti-floating point reinforcement structure refers to the above-mentioned embodiment. Since the hollow floor adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, after adopting the anti-floating point reinforcement structure, the hollow floor of the utility model can realize the mutual fixation of the floor steel bars and the building formwork. During the pouring process, the core mold and the steel bars connected to the core mold will float up due to the buoyancy of the concrete. The anti-floating point reinforcement structure fixes the floor steel bars and realizes the anti-floating of the core mold and the floor steel bars. The traditional anti-floating method of tying iron wires requires drilling holes in the building formwork and passing iron wires through the upper and lower sides of the building formwork to tie and fix the floor steel bars to the steel pipes of the formwork frame located under the building floor. The construction process requires at least two operators to drill holes and tie iron wires above and below the formwork, and the drilling points may sometimes be inaccurate during the drilling process and may need to be re-drilled, which is not very accurate, further increasing the workload of anti-floating point construction. The present anti-floating point reinforcement structure only needs to place the bending portion 1 on the floor steel bar, and allow the connecting portion 2 to be detachably connected to the building formwork, so that the floor steel bar can be pressed onto the building formwork, eliminating the need for drilling and tying wires, reducing the workload, and only one operator is required to complete all operations during the actual anti-floating point construction process, reducing the labor cost required for anti-floating point construction, so the present anti-floating point reinforcement structure has a high economic benefit. When the hollow floor slab of the utility model is demolded, the building formwork needs to be removed, and the main body of the connecting portion 2 and the bending portion 1 are retained in the inner concrete, while the bottom surface of the connecting portion 2 exposed on the concrete surface does not need additional grinding treatment because it is relatively flat, which not only reduces the workload during demolding, but also ensures the apparent quality of the concrete surface.
[0042] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
