Description

Technical Field

[0001] The utility model relates to the technical field related to construction, and in particular to a reinforced composite floor slab and a reinforcement device. Background Art

[0002] In the field of construction engineering technology, composite floor is a common building structure, which is composed of two layers of floor panels connected by adhesive materials, and has the advantages of high strength, light weight, and convenient construction. However, due to improper construction quality control or the influence of environmental factors, composite floor may have hollowing phenomenon during use, that is, the upper and lower floors are not well connected or partially hollowed out, which will lead to a decrease in the structural bearing capacity and limited use function.

[0003] In order to solve the hollowing phenomenon of composite floor slabs, holes are usually opened on the board surface, and then slurry, such as underwater epoxy, is poured into the gaps between the floor slabs through these holes. The principle of this method is to use the viscosity and fluidity of the slurry to inject it into the gaps between the floor slabs, thereby filling these gaps and increasing the stability of the floor slabs. The existing grouting devices are often complicated and inconvenient to operate, and manual monitoring and adjustment are required during the grouting process, which is inefficient. After grouting, the gaps are only filled with slurry, and the structural strength after repair is poor. It is also impossible to effectively block the expansion joints on the board surface, which easily causes water and dirt to re-enter the gaps between the floor slabs, causing the floor slabs to become hollow and damaged again.

[0004] Therefore, in order to solve the hollowing phenomenon of composite floor slabs in the prior art, when slurry is poured into the gaps between the floor slab plates, there is a problem that the structural strength after repair is poor and hollowing and damage are prone to occur again. Utility Model Content

[0008] The outer diameter of the catheter body is smaller than the inner diameter of the grouting hole, the length of the catheter body is smaller than or equal to the length of the grouting hole, and the outer wall of the catheter body is provided with a plurality of overflow holes at intervals along the circumferential direction. The catheter body is filled with slurry, and the slurry fills the catheter body, overflows from the overflow holes and fills the gap between the outer wall of the catheter body and the inner wall of the grouting hole.

[0009] By adopting the above technical scheme, after the reinforced composite floor disclosed by the utility model is opened with a grouting hole, a conduit body is inserted into the grouting hole for grouting, and because the outer wall of the conduit body is provided with a plurality of overflow holes, the slurry filled and injected into the conduit body can overflow from the overflow holes and fill the gap between the outer wall of the conduit body and the inner wall of the grouting hole, and the conduit body remains in the grouting hole and is integrated with the composite floor, and the conduit body not only completes the restoration of the hollow area, but also plays a role in replacing the steel bar for support, and the conduit body provides connection points and support points in the hollow area of ​​the composite floor, thereby improving the overall bearing capacity and stability of the composite floor, and the strength is higher after repair, and the overflow holes can ensure that the slurry is evenly distributed and evenly filled between the conduit body and the inner wall of the grouting hole, and after repairing the hollowing of the composite floor, it can also prevent the recurrence of hollowing and damage problems.

[0010] After the slurry is filled in the conduit body, the opening of the conduit body is blocked by the sealing part, and the sealing part also blocks the port of the grouting hole on the side surface of the reinforced composite floor slab at the same time. By setting the sealing part, the problem that the existing grouting device cannot effectively seal the expansion joint opening at the board surface is solved, the slurry leakage can be prevented, and water and dirt can be prevented from entering the gap between the floor slab panels again, effectively preventing the floor slab panels from hollowing and damage.

[0011] In another preferred embodiment, the interior of the catheter body has a hollow grouting cavity; the inner side wall of the opening end of the catheter body is provided with an internal thread. The end of the plugging portion is adapted to the opening, and the outer wall of the end of the plugging portion is provided with an external thread adapted to the internal thread. The threaded connection makes it more convenient to screw and install the plugging portion.

[0012] Further preferably, a variable diameter insertion end is provided at one end of the catheter body away from the blocking portion, and a plurality of overflow holes are also provided at intervals along the circumferential direction on the outer wall portion of the variable diameter insertion end.

An overflow hole is provided on the outer wall of the conduit body in the grouting hole to facilitate the slurry to overflow and tightly bond with the inner wall of the grouting hole. The problem that the existing grouting device cannot effectively seal the expansion joint at the board surface is solved by providing a sealing part, so as to prevent water and dirt from entering the gap between the floor plate materials again.

[0042] As mentioned in the prior art, in order to solve the hollowing of composite floor slabs, the prior art generally adopts the method of drilling holes on the board surface, and then pouring slurry into the hollow or gap parts between the floor slab plates through the holes, so that the slurry flows in the hollow or gap area and fills the gap or hollow area. However, this grouting device is often complicated and inconvenient to operate, and the injection amount and pressure of the poured slurry need to be manually monitored and adjusted during the grouting process. Moreover, after grouting, the gap is only filled with slurry, and the structural strength after repair is poor, and the expansion joints at the board surface cannot be effectively sealed, which easily causes water and dirt to re-enter the gap between the floor slab plates, causing the floor slab plates to hollow and be damaged again. When it is necessary to enhance the strength of the filling and repairing area, it is necessary to fill the hollow or gap with structures such as steel bars, and then fill with slurry. The construction process is complicated and the construction efficiency is low.

[0043] To this end, the utility model discloses a reinforced composite floor slab, wherein a grouting hole is opened on the reinforced composite floor slab, and a grouting conduit is embedded and inserted in the grouting hole, and then slurry is injected into the grouting conduit, and a plurality of overflow holes are arranged at intervals along the circumferential direction on the outer wall of the grouting conduit. After the slurry is filled into the conduit body, it will overflow through the overflow holes and fill the gap between the outer wall of the conduit body and the inner wall of the grouting hole. After the slurry is filled, a sealing part is installed at the end of the conduit body to seal the opening of the conduit body and the port of the grouting hole. While filling the hollow of the reinforced composite floor slab, the grouting conduit is retained in the reinforced composite floor slab, which not only completes the restoration of the hollow area, but also plays a role in replacing the steel bar for support, and at the same time improves the overall bearing capacity and stability of the reinforced composite floor slab, so that the strength of the reinforced composite floor slab after repair is higher.

[0044] Example 1

[0045] Specifically, the implementation method of this embodiment discloses a reinforced composite floor slab, see Figure 1 and Figure 2 The reinforced composite floor 100 includes at least two layers of floor panels 110 that are overlapped in sequence. In this embodiment, two layers of overlapping floor panels 110 are taken as an example for illustration. A grouting hole 120 is opened on the surface of one side of the reinforced composite floor 100. In this embodiment, the reinforced composite floor 100 is arranged in the horizontal direction as an example. Therefore, in this embodiment, the thickness direction A of the reinforced composite floor 100 is the vertical direction, the drilling direction of the grouting hole 120 is also the vertical direction, and in this embodiment, the uppermost floor panel 110 is penetrated in the thickness direction A of the reinforced composite floor 100. The grouting conduit 200 is first embedded in and filled in the grouting hole 120. The grouting conduit 200 includes a detachable conduit body 210 and a plugging portion 220. The conduit body 210 is entirely located in the grouting hole 120. The conduit body 210 has a hollow grouting cavity (not shown in the figure) inside. One end of the conduit body 210 is opened close to the grouting hole 120. The outer wall of the conduit body 210 is provided with a plurality of overflow holes 211 at intervals along the circumferential direction. Then, the grout is poured through the opening of the conduit body 210. When pouring the grout, the grout will flow in the grouting cavity of the conduit body 210 and then flow to the conduit body 210. 0, then overflows through the overflow hole 211, and then flows into the hollow area, gap or grouting hole 120 of the reinforced composite floor 100. When the hollow area and the grouting hole 120 of the reinforced composite floor 100 are injected with slurry, the slurry plane in the conduit body 210 will rise by grouting until it fills the grouting hole 120 (including the hollow area or gap inside) and fills the conduit body 210. Finally, the sealing part 220 is detachably arranged at the end of the conduit body 210, and the opening of the conduit body 210 and the port 121 of the grouting hole 120 on one side surface of the reinforced composite floor 100 are sealed.

[0046] It should be noted that in the present embodiment, the reinforced composite floor 100 can be 3 layers, 4 layers, 5 layers or even more layers of overlapping floor panels 110. For example, when the reinforced composite floor 100 is arranged with 4 layers, the area where hollowing occurs is the second layer, and the grouting holes 120 only need to penetrate one or two layers of floor panels 110. When the area where hollowing occurs is the third layer, the grouting holes 120 need to penetrate two or three layers of floor panels 110. That is to say, in the actual application scenario, the opening position and opening depth of the grouting holes 120 are adjusted according to the thickness of the floor panel 110 and the hollowing area or the area to be filled, and the opening aperture of the grouting holes 120 is also adjusted according to the needs to achieve reinforcement of the composite floor.

[0047] The reinforced composite floor 100 disclosed in this embodiment can also be used in ground paving projects or the reinforcement of floor external insulation boards. For example, when applied to the surface of a floor or the external insulation board of a floor, the grouting holes 120 need to be drilled in the horizontal direction. It can be understood that the length of the duct body 210 can be adjusted according to needs, and the duct body 210 can be set as a duct with different cross-sections. In this embodiment, it is preferably set as a cylindrical duct. The opening size of the overflow hole 211 opened on the duct body 210 must at least ensure that the slurry can flow out through the overflow hole 211.

[0048] More specifically, the outer diameter of the conduit body 210 is smaller than the inner diameter of the grouting hole 120. For example, when the inner diameter of the grouting hole 120 is 30 mm, the outer diameter of the conduit body 210 can be set to 20 mm, 25 mm, 27 mm, etc. There is a gap 122 between the outer wall of the conduit body 210 and the inner wall of the grouting hole 120. The slurry flows out of the overflow hole 211 and flows into the gap 122. When there is a hollow, it will also flow into the hollow area to fill it. Then the slurry fills all the gaps 122 in turn and fills the conduit body 210. The length dimension of the duct body 210 is less than or equal to the length dimension of the grouting hole 120. Preferably, in the present embodiment, the length dimension of the duct body 210 is slightly smaller than the length dimension of the grouting hole 120. For example, when the length dimension of the grouting hole 120 is 200 mm, the length dimension of the duct body 210 is set to 180 mm, and a certain size of installation position is reserved for the sealing part 220. Then, after the sealing part 220 is installed at the opening of the duct body 210, the top plane of the sealing part 220 is just flush with the top plane of the reinforced composite floor 100.

[0049] In this embodiment, the plugging portion 220 and the open end of the catheter body 210 can be assembled and connected by various methods such as flange connection, threaded connection, plug-in connection, interference fit connection, etc. This embodiment preferably adopts a threaded connection method, and an internal thread is provided on the inner side wall of the open end of the catheter body 210. The end of the plugging portion 220 is adapted to the opening, and the outer wall of the end of the plugging portion 220 is provided with an external thread adapted to the internal thread. Through such a setting, after the slurry is filled in the catheter body 210, the end of the plugging portion 220 is aligned with the opening so that the internal thread and the external thread are adapted and then screwed and installed, which has the advantages of simple and efficient connection, and also has the advantages of good sealing performance and convenient maintenance, which is conducive to standardized and mass production applications.

[0050] Further preferably, a variable diameter insertion end 212 is provided at one end of the catheter body 210 away from the blocking portion 220, and a plurality of overflow holes 211 are also provided at intervals on the outer wall of the variable diameter insertion end 212 along the circumferential direction. The catheter body 210 can be a square cylindrical structure, a prismatic cylindrical structure, a cylindrical cylindrical structure, etc., and the variable diameter insertion end 212 can be a cone, a pyramid, etc. Figure 1 In this embodiment, the catheter body 210 is preferably configured to be a cylindrical tube structure, and the variable diameter insertion end 212 is conical. The conical variable diameter insertion end 212 is more convenient for the catheter body 210 to be inserted into the grouting hole 120. It should be noted that in order to facilitate the slurry to flow out through the overflow hole 211, in this embodiment, a plurality of overflow holes 211 are densely arranged on the outer wall of the catheter body 210 and the variable diameter insertion end 212.

[0051] More specifically, see Figure 1 The plugging portion 220 includes an opening plugging portion 221 and a port plugging portion 222. In a preferred implementation disclosed in this embodiment, the plugging portion 220 is configured as a cap-shaped structure, and the outer diameter of the port plugging portion 222 is greater than the outer diameter of the opening plugging portion 221, because the inner diameter of the grouting hole 120 is greater than the outer diameter of the catheter body 210, and the opening plugging portion 221 is used to plug the opening of the catheter body 210, and the port plugging portion 222 is used to plug the port 12 of the grouting hole 120. 1. Specifically, the outer wall of the opening sealing portion 221 is provided with an external thread that is adapted to the internal thread at the opening of the conduit body 210. The opening sealing portion 221 is detachably sealed with the opening of the conduit body 210 through the thread. The port sealing portion 222 is located on the side of the opening sealing portion 221 away from the conduit body 210 and covers the port 121 of the grouting hole 120 on one side surface of the composite floor, wherein a sealing colloid is poured between the port sealing portion 222 and the opposite surface of one side surface of the composite floor. That is to say, after the port sealing portion 222 seals the grouting hole 120, a gap may exist between the port sealing portion 222 and the composite floor slab. The gap is formed between the outer peripheral surface of the port sealing portion 222 and the inner wall surface of the grouting hole 120 of the reinforced composite floor slab 100 (that is, the relative surface between the port sealing portion 222 and one side surface of the composite floor slab). Therefore, the gap is sealed by a sealing colloid, which can be various common structural adhesives or curable fluid glues, and this embodiment does not make any specific limitation on this.

[0052] Further preferably, the catheter body 210 is made of a metal material, such as iron or steel, and the slurry includes but is not limited to any one of underwater epoxy grouting, cement mortar, and grouting resin. For example, it can also be sodium silicate grouting, polyurethane grouting, latex grouting, etc. This embodiment does not make specific limitations on this.

[0053] See also Figure 5 In this embodiment, a plurality of grouting holes 120 are arranged at intervals on the reinforced composite floor 100, for example, they are arranged in a plum blossom pattern at a certain distance, and a grouting conduit 200 is arranged in each grouting hole 120. It should be noted that in actual application scenarios, the grouting holes 120 can also be arranged only in the hollow part according to the needs, and then the grouting conduit 200 is inserted for grouting.

[0054] After the grouting hole 120 is opened in the reinforced composite floor 100 disclosed in the present embodiment, the conduit body 210 is inserted into the grouting hole 120 for grouting. Because the outer wall of the conduit body 210 is provided with a plurality of overflow holes 211, the slurry filled and injected into the conduit body 210 can overflow from the overflow holes 211 and fill the gap 122 between the outer wall of the conduit body 210 and the inner wall of the grouting hole 120. The design of the plurality of overflow holes 211 ensures uniform distribution of the slurry, thereby improving the repair quality. The duct body 210 remains in the grouting hole 120 and is integrated with the reinforced composite floor 100. The duct body 210 not only completes the restoration of the hollow area, but also plays a role in replacing the steel bars for support. The duct body 210 provides connection points and support points in the hollow area of ​​the reinforced composite floor 100, thereby improving the overall bearing capacity and stability of the reinforced composite floor 100, and the strength is higher after repair. The overflow hole 211 can ensure that the slurry is evenly distributed and evenly filled between the duct body 210 and the inner wall of the grouting hole 120, and after repairing the hollowing of the reinforced composite floor 100, it can also prevent the recurrence of hollowing and damage problems.

[0055] After the conduit body 210 is filled with slurry, the opening of the conduit body 210 is blocked by the sealing part 220, and the sealing part 220 also blocks the port 121 of the grouting hole 120 on the side surface of the reinforced composite floor 100. By setting the sealing part 220, the problem that the existing grouting device cannot effectively seal the expansion joint opening at the board surface is solved, and slurry leakage can be prevented, and water and dirt can be prevented from re-entering the gap 122 between the floor panels 110, which effectively prevents the floor panels 110 from hollowing and damage.

[0056] Example 2

[0057] This embodiment also discloses a reinforcement device for reinforcing the composite floor slab in Embodiment 1. The reinforcement device includes a grouting assembly 300. Figure 2~Figure 4 ,in Figure 2 and Figure 3 FIG. 2 is a schematic diagram of the grouting assembly 300 pouring grout into the grouting conduit 200. Figure 4 A schematic diagram of the structure of the reinforcement device.

[0058] See also Figure 4The grouting assembly 300 includes a grouting part 310, which is detachably connected to the opening of the duct body 210. In this embodiment, the grouting part 310 is configured to have a structure similar to the plugging part 220. The grouting part 310 has a grouting pipeline 311, which is connected to an external slurry pool. After the grouting part 310 is installed at the opening of the duct body 210 and the connection strength is ensured to be reliable, the grouting pipeline 311 is used to pour slurry into the duct body 210. After the duct body 210 is filled with slurry, the grouting part 310 is removed from the opening of the duct body 210. Finally, the opening of the duct body 210 and the port 121 of the grouting hole 120 on one side surface of the reinforced composite floor 100 are blocked by the plugging part 220. The grouting assembly 300 also includes a pressure detection component 320, which is arranged on the side of the grouting part 310 away from the catheter body 210. The pressure detection end of the pressure detection component 320 passes through the grouting part 310 and extends into the catheter body 210. Preferably, the pressure detection component 320 of this embodiment includes a pressure display instrument and a pressure sensor (not shown in the figure). The pressure sensor is arranged at the pressure detection end. The pressure sensor can be any one of the common piezoresistive pressure sensors, capacitive pressure sensors or Hall plate pressure sensors. The pressure sensor detects the pressure value of the slurry in the catheter body 210 and transmits it to the pressure display instrument to display the specific pressure. When the pressure reaches the threshold or the pressure value does not change, the grouting of the slurry is stopped. The pressure inside the catheter body 210 can be clearly and accurately measured and it can be determined whether the slurry is full.

[0059] The grouting part 310 and the opening of the catheter body 210 are detachably connected by any one of threaded connection, flange connection, clamping, and plugging. In this embodiment, because the opening of the catheter body 210 is provided with an internal thread, the outer wall of the grouting part 310 is provided with an external thread that matches the internal thread, so it is preferred that the grouting part 310 and the opening of the catheter body 210 are connected by threaded connection. It has the advantages of simple and efficient connection, good sealing performance and convenient maintenance, which is conducive to standardized and mass production applications.

[0060] The grouting assembly 300 can be used to quickly and conveniently inject slurry into the grouting hole 120. The grouting pipeline 311 is connected to the external slurry pool to provide slurry to the grouting catheter 200. The flow and pressure of the slurry can be controlled more accurately. The grouting is simple, convenient and efficient, and is convenient for batch operations.

[0061] In summary, the utility model discloses a reinforced composite floor 100 and a reinforcement device. The reinforced composite floor 100 is grouting by opening a grouting hole 120 and inserting a conduit body 210 into the grouting hole 120. The conduit body 210 is retained in the grouting hole 120 to replace the steel bar, which simplifies the construction process and increases the overall bearing capacity and stability of the composite floor. An overflow hole 211 is provided on the outer wall of the conduit body 210 in the grouting hole 120 to facilitate the slurry to overflow and tightly adhere to the inner wall of the grouting hole 120. The sealing part 220 is provided to solve the problem that the existing grouting device cannot effectively seal the expansion joint opening at the board surface, prevent water and dirt from entering the gap 122 between the floor plate materials 110 again, and when the grouting assembly 300 is used to pour the slurry into the conduit body 210, the pressure detection component 320 is used to monitor the pressure change in the grouting process in real time, so as to accurately judge the filling condition of the slurry, avoid insufficient or excessive grouting, and improve the grouting effect. After being filled with slurry, the sealing part 220 is installed by threaded installation. The construction is simple, convenient and more efficient, which effectively reduces the construction cost and labor input, and can be easily applied to various ground laying projects, and has broad application prospects.

[0062] Finally, the reinforcement method or steps of the reinforcement device disclosed in the utility model for reinforcing the composite floor 100 are briefly described:

[0063] First, a grouting hole 120 is drilled on the composite floor slab. Preferably, the grouting hole 120 is opened in a hollow area, and the inner diameter of the grouting hole 120 is larger than the outer diameter of the conduit body 210 to be installed. After the grouting hole 120 is drilled, the inner wall surface of the grouting hole 120 can be roughened or cleaned. After cleaning, the conduit body 210 is placed into the grouting hole 120, and then the conduit body 210 is grouted through the grouting assembly 300. Before grouting, the grouting part 310 and the opening of the conduit body 210 are connected and tightened by threaded connection, and then the grouting pipeline 311 is used to pour slurry into the interior, and the pressure value on the pressure display instrument of the pressure detection component 320 is observed. When the pressure value reaches the threshold value of the slurry filling, or the pressure value on the pressure display instrument shows that the pressure is no longer increasing, it means that the slurry is full, and the grouting is stopped at this time. Then, the grouting assembly 300 is removed by screwing, and the conduit body 210 is left in the grouting hole 120. Then, the prepared plugging part 220 is installed at the opening of the conduit body 210 by screwing and plugging the port 121 of the grouting hole 120. Finally, the gap between the board surface of the composite floor and the plugging part 220 is sealed by applying glue.
