[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiments of the present application disclose a ground elevation control device and a construction method.

[0035] In a first aspect, an embodiment of the present application discloses a ground elevation control device.

[0036] Reference Figure 1 and Figure 2 , a ground elevation control device, comprising a vertical pole 1, the vertical pole 1 is 50mm long and 12mm in diameter; a 2mm thick fixing gasket 2 is fixedly connected to the lower end of the vertical pole 1, the vertical pole 1 and the fixing gasket 2 are arranged perpendicular to each other, the vertical pole 1 is arranged at the axis of the fixing gasket 2, and four fixing holes 21 with a diameter of 2mm are opened on the fixing gasket 2. The four fixing holes 21 are penetrated from top to bottom with mounting nails 22. During installation, the fixing gasket 2 is placed on the upper end surface of the floor slab, and then a plurality of mounting nails 22 are passed through the fixing holes 21, and the mounting nails 22 are driven into the interior of the floor slab, and the mounting nails 22 are extended to the bottom of the fixing gasket 2 to fix the vertical pole 1, which can effectively reduce the occurrence of the vertical pole 1 toppling during the subsequent concrete pouring; at this time, the vertical pole 1 has been fixed to the upper end of the floor slab, and multiple ground elevation control devices can be arranged on the floor slab, which can be placed according to the corner position of the ground separation joint, or can be densely arranged according to the integer multiple relationship of the separation joint width, so as to improve the precision requirement of large-area construction.

[0037] The installation nails 22 in this embodiment are preferably cement nails, which can fix the fixing gasket 2 on the floor.

[0038] When constructing the floor slab, the construction workers can also pre-embed the vertical pole 1 and the fixing gasket 2 into the floor slab, so that the vertical pole 1 extends to the top of the floor slab, which can further save the construction efficiency.

[0039] Reference Figure 1 and Figure 2 The outer surface of the vertical pole 1 is provided with a scale for elevation identification. After installing multiple ground elevation control devices, the scale elevation needs to be uniformly reviewed to reduce the measurement error caused by the uneven original foundation surface. For the position where the elevation error exists on the original foundation surface, appropriate padding or cutting can be carried out after verification. Only after the scale elevation is verified, large-scale construction can be carried out to ensure the accuracy of large-area ground construction with precise scale; then concrete can be poured on the floor slab. After the poured concrete reaches the specific scale of several vertical poles 1, the pouring can be stopped to complete the construction. The flatness of the poured surface can be checked on multiple vertical poles 1, thereby improving the flatness of the poured surface.

[0040] Reference Figure 1 and Figure 2Before pouring, a steel mesh is usually built into the area where pouring is required. Four hooks 3 for placing steel bars are arranged vertically and evenly on one side of the length direction of the vertical pole 1. The distance between adjacent hooks 3 is 10 mm to meet the requirements of different steel mesh pad heights. By providing hooks 3 of more heights for selection, the effect of convenient construction is achieved.

[0041] Reference Figure 2 and Figure 3 After several vertical poles 1 are installed on the floor slab, the steel mesh can be placed.

[0042] Among them, the steel mesh is a mesh formed by a number of steel bars of different heights and perpendicular to each other.

[0043] Reference Figure 2 and Figure 3 The hook 3 includes a horizontal rod 31 and a vertical rod 32. The length of the horizontal rod 31 is 5 mm. The end of the horizontal rod 31 away from the vertical rod 1 is fixedly connected to the vertical rod 32. The vertical rod 32 is fixedly connected to the upper end of the horizontal rod 31. The end of the horizontal rod 31 close to the vertical rod 1 is fixedly connected to the vertical rod 1. Reference Figure 2 and Figure 3 , the staff can place several steel bars on the upper end of the hook 3 with the lowest height among the several vertical poles 1, and then place several steel bars on the upper end of the hook 3 with the second to last height among the several vertical poles 1, so that the two groups of steel bars are arranged in a perpendicular and crossed direction to each other; then repeat the above steps again to complete the arrangement of the steel mesh. The staff does not need to use stirrups to support the steel mesh, thereby improving the construction efficiency and the functionality of the ground elevation control device. The hook 3 can be used to support the steel mesh, and the scale on the vertical pole 1 can be used to identify the elevation.

[0044] Reference Figure 2 and Figure 3 By laying out steel mesh, the structural strength and stability of concrete can be significantly improved after the subsequent pouring of concrete, effectively enhancing the bearing capacity of the building; and by evenly distributing the load, the steel mesh can reduce stress concentration in the structure, prevent the occurrence of cracks, and extend the service life of the ground structure.

[0045] Reference Figure 1 and Figure 2 After the steel mesh is laid out, the concrete can be poured. After pouring to a specific height of the vertical pole 1, the remaining part of the vertical pole 1 located at the upper end of the pouring ground can be cut off after the concrete is completely solidified. Depending on the working conditions, the vertical pole 1 can also be cut after determining the pouring height of the concrete before pouring the concrete. The staff can make a choice according to different working conditions.

[0046] The vertical pole 1 is made of plastic material, which is convenient to process and has low cost. It is also easier to cut the vertical pole 1 when cutting it, thereby improving the efficiency of the construction.

[0047] Reference Figure 4 and Figure 5 The ground elevation control device also includes a connecting rod 4, which is detachably connected to the upper end of the vertical pole 1. If the thickness of the concrete to be poured is large and the height of the vertical pole 1 is not high enough, the connecting rod 4 can be installed on the upper end of the vertical pole 1. The outer surface of the connecting rod 4 is also provided with a scale for elevation identification, and then the height of the scale is increased, and then the concrete can be poured. After pouring to a specific height of the connecting rod 4, after the concrete is completely solidified, the connecting rod 4 located at the upper end of the pouring ground can be cut off, which has high applicability.

[0048] Among them, according to different working conditions, the connecting rod 4 can also be cut after determining the pouring height of the concrete before pouring the concrete, and the staff can make a choice according to different working conditions.

[0049] Reference Figure 4 and Figure 5 A threaded rod 41 is extended from the lower end of the connecting rod 4, and a threaded groove 11 adapted to the threaded rod 41 is opened at the upper end of the vertical rod 1; the connection between the vertical rod 1 and the connecting rod 4 is completed by screwing the threaded rod 41 into the threaded groove 11, which has a simple structure and is convenient to connect.

[0050] Among them, the connecting rod 4 is also made of plastic. The connecting rod 4 made of plastic is easier to process and has lower cost. When the design thickness of the concrete does not match the device modulus, it can be processed by horizontal cutting along the entire scale line position to meet on-site use requirements. It is more convenient to cut the connecting rod 4 and the vertical pole 1.

[0051] Reference Figure 4 and Figure 5 Hooks 3 are also arranged vertically at equal intervals on one side of the length direction of the connecting rod 4. The staff can also place steel mesh on the hooks 3 of the connecting rod 4, thereby improving the structural strength of the subsequent concrete. There is no need to use stirrups to support the steel mesh, thereby improving the efficiency of construction.

[0052] Reference Figure 4 and Figure 5 The hooks 3 on the vertical pole 1 and the connecting rod 4 are both made of steel. The steel hooks 3 can hook the steel mesh to meet the thickness requirement of the steel mesh protective layer. After pouring concrete, the hooks 3 can also play an anchoring effect with the ground concrete, thereby strengthening the connection between concrete and steel bars and further improving the structural strength of the ground.

[0053] The working principle of a ground elevation control device in an embodiment of the present application is as follows: first, a fixed gasket 2 is placed on the upper end surface of the floor slab, and then a cement nail is passed through the fixing hole 21, and the cement nail is driven into the floor slab to fix the fixed gasket 2, and a plurality of ground elevation control devices are installed on the floor slab in sequence, and then a steel mesh is placed on the hook 3 to improve the structural strength of the concrete after pouring, and then the concrete can be poured; if the thickness of the concrete to be poured is relatively large, a connecting rod 4 can be threadedly connected to the upper end of the vertical pole 1 to increase the height of the scale, and a steel mesh can be placed on the hook 3 of the connecting rod 4 to improve the structural strength of the concrete after pouring, and then the concrete can be poured. After pouring to a specific height of the connecting rod 4, the connecting rod 4 located at the upper end of the pouring ground can be cut off, and the applicability is relatively high.

[0054] Embodiment 2: Reference Figure 6 and Figure 7 The difference between the second embodiment and the first embodiment lies in the different arrangements of the vertical rod 1 and the connecting rod 4.

[0055] Reference Figure 6 and Figure 7 A number of marking holes 5 are provided on the vertical pole 1 and the connecting rod 4. The marking holes 5 correspond to the scales. The height of the marking holes 5 is the same as the height of the corresponding scales. A number of marking holes 5 are provided on the side of the vertical pole 1 away from the hook 3. A number of marking holes 5 can be inserted with marking plates 6 adapted to the marking holes 5 for elevation identification. After determining the height to be poured, the marking plate 6 is inserted into the marking hole 5 in the opposite direction of the determined scale. When the staff is pouring, they can slowly pour by checking the distance between the concrete liquid level and the marking plate 6, thereby improving the convenience of locating the concrete height during pouring.

[0056] Embodiment three: Reference Figure 8 The difference between the third embodiment and the above embodiments is that the setting of the hook 3 is different.

[0057] Reference Figure 8 There are four hooks 3 on the vertical pole 1, which are arranged as the first hook, the second hook, the third hook and the fourth hook from top to bottom; the first hook and the third hook are both vertically slidably connected to the vertical pole 1; when placing the steel mesh, first place a number of steel bars on the fourth hook of the vertical pole 1, and then place a number of steel bars on the third hook of the vertical pole 1. At this time, the third hook is pressed and slides along the height direction of the vertical pole 1. At this time, the steel bar fits on the steel bar hung on the fourth hook, and the subsequent staff can easily tie the steel bars, thereby improving the convenience of the staff in construction.

[0058] Among them, the first hook and the third hook are slidably connected to the vertical pole 1, which is a prior art. The first hook and the third hook can be slid on the vertical pole 1, and no more details will be given in this embodiment.

[0059] In a second aspect, an embodiment of the present application discloses a construction method of a ground elevation control device.

[0060] A construction method for a ground elevation control device comprises the following steps: S1: Place the fixing gasket 2 on the floor slab, drive the mounting nails 22 through the fixing holes 21 and into the floor slab, fix the fixing gasket 2 on the floor slab, and if the concrete pouring thickness exceeds 50 mm, screw the threaded rod 41 of the connecting rod 4 into the screw hole of the vertical rod 1; S2: Repeat step S1 to install poles 1 at the four corners of the floor, and then install multiple poles 1 at equal intervals on the floor between the poles 1; S3: placing a plurality of reinforcing bars horizontally in sequence on the hook 3 of the lowest height where no reinforcing bars are currently placed; placing a plurality of reinforcing bars on the hook 3 of the second-to-last height, crossing with the previously placed reinforcing bars; S4: Repeat step S3 to complete the layout of the steel mesh.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
