[0002] In the construction industry, precise control of cast-in-place slab thickness is a key link to ensure structural safety and construction quality, especially when dealing with large-area concrete floors, floors and roofs. The commonly used slab thickness control methods in the industry, such as the traditional marking high-pull wire control method, have been used in practice for a long time, but due to the elevation error in the operation process, the inaccuracy of the control height and the relative lag in the pouring progress, it is difficult to meet the high-precision requirements of modern construction. Another common method is to control the slab thickness through a slab thickness controller designed with fixed dimensions. However, this method is inadequate and difficult to adapt flexibly when there are different slab thickness requirements on the same floor and the slope of the floor or roof slab requires slope finding.

[0027] Specific embodiments, such as Figures 1 to 6 A height-adjustable cast-in-place floor slab thickness control device is shown, comprising a base 2 that can be fixed to a contact surface, the base 2 is connected to an adjusting mechanism 1 with adjustable height, and the upper end of the adjusting mechanism 1 is connected to a positioning device 3 for determining the finished casting surface.

[0028] Preferably, the adjustment mechanism 1 includes a lower adjustment seat 11 disposed on the base 2, and an upper adjuster 12 is movably connected to the lower adjustment seat 11. By movably connecting the upper adjuster 12 to the lower adjustment seat 11, the height adjustment function of the adjustment mechanism 1 is realized, making the height adjustment of the device more flexible and accurate, thereby meeting the control requirements when pouring floors of different thicknesses; the upper adjuster 12 includes a connecting member 121 movably connected to the lower adjustment seat 11, so that the connection between the upper adjuster 12 and the lower adjustment seat 11 is more stable and reliable, and a supporting device 122 is provided between the connecting member 121 and the positioning device 3. The design of the supporting device 122 enables the positioning device 3 to be stably connected to the upper adjuster 12. This supporting effect ensures the accuracy and stability of the positioning device 3, thereby improving the accuracy of determining the finished pouring surface.

[0029] Preferably, the lower adjustment seat 11 is a hollow sleeve for the connector 121 to extend into, and the connector 121 is a sleeve adapted to the inner diameter of the lower adjustment seat 11, which simplifies the structure of the device and makes the height adjustment smoother and more convenient. The connector 121 is a sleeve adapted to the inner diameter of the lower adjustment seat 11, which ensures the tightness and stability of the connection. At the same time, this also makes it difficult for the connector 121 to shake or deflect during the up and down adjustment process, further improving the reliability of the device. The lower adjustment seat 11 is provided with a locking mechanism 13 to fix the upper adjuster 12 to the lower adjustment seat 11. The locking mechanism 13 can fix the upper adjuster 12 and the lower adjustment seat 11 after adjusting to a suitable height. This fixing effect not only ensures the stability of the device during the construction process, but also prevents the height change caused by the instability of the device, thereby preventing the floor slab from having quality problems during pouring.

[0030] Preferably, the inner wall of the lower adjusting seat 11 is provided with a thread, and the outer wall of the connecting piece 121 is provided with a thread adapted to the lower adjusting seat 11, so that the two are threadedly connected. The adjustment method of the threaded connection makes the height adjustment more precise and flexible. By rotating the connecting piece 121, its relative position with the lower adjusting seat 11 can be precisely controlled, thereby achieving precise adjustment of the floor thickness. In addition, the threaded connection also has a certain self-locking property, which can resist interference from external factors to a certain extent, such as reducing the vibration generated by concrete vibration during pouring operations. This self-locking property enables the device to remain stable after the height is fixed and is not easily affected by construction activities.

[0031] Preferably, the locking mechanism 13 includes a reinforcement channel 131 protruding outward from one side of the lower adjustment seat 11, and a locking member 132 connected to the side end of the connecting member 121 is provided in the reinforcement channel 131. The locking member 132 passes through the reinforcement channel 131 and is connected to the side end of the connecting member 121 to limit the movement of the connecting member 121, thereby further reinforcing the relative position between the upper adjuster 12 and the lower adjustment seat 11.

[0032] Preferably, the reinforcement channel 131 is in the shape of a truncated cone with a thread inside. The locking piece 132 is a screw that matches the reinforcement channel 131. The truncated cone shape enhances the bearing capacity of the reinforcement channel 131. Providing threads in the channel and using screws as the locking piece 132 can improve the firmness of the connection between the two, while further improving the limiting capacity of the connecting piece 121.

[0033] Preferably, the supporting device 122 includes a first supporting plate 1221 connecting the positioning device 3 and the connecting member 121, and a second supporting plate 1222 forming a T-shaped plate is connected to one side of the first supporting plate 1221, thereby increasing the load-bearing area of ​​the supporting device 122 and improving the supporting capacity. It can also effectively disperse external forces and reduce the pressure on a single supporting point. A steel bar bracket 1223 for supporting steel bars is also provided on the other side of the first supporting plate 1221 to ensure the position and stability of the steel bars during the pouring process, while reserving the height of the protective layer to protect the steel bars.

[0034] Preferably, a first rib 1224 is provided on the upper part of the first support plate 1221 and is fixedly connected to the lower end of the positioning device 3, and a second rib 1225 is provided on the lower part of the first support plate 1221 and is fixedly connected to the upper end of the connecting member 121; the upper and lower ends of the steel bar bracket 1223 are respectively connected to the upper end of the first rib 1224 and the upper end of the second rib 1225. By adding the first rib 1224 and the second rib 1225, and optimizing the connection method between the steel bar bracket 1223 and the rib, the structural strength and stability of the device are significantly improved.

[0035] Preferably, the base 2 is a regular octagonal mounting base plate, and four fixing holes 21 are arranged in an array along the central circumference of the base 2. The regular octagonal structure has a uniform force distribution characteristic, which can effectively resist the external force during the construction process and ensure the stability of the device when it is in a fixed position. In addition, by inserting fixings, such as bolts or steel bars, into the fixing holes 21, the base 2 can be firmly fixed to the ground to prevent the device from shifting or tipping over during the construction process. In addition, other regular polygonal mounting base plates and additional fixing holes 21 can be selected according to actual needs to ensure that the device has sufficient stability and flexibility when fixed to meet various construction needs.

[0036] Preferably, the upper end of the lower adjustment seat 11 is sleeved with an anti-seepage device 4. In this embodiment, an anti-seepage water-stop ring is selected to prevent water leakage of the floor slab in the later stage and erosion of the internal reinforced concrete structure.

[0037] Preferably, in the aforementioned height-adjustable cast-in-place floor thickness control device, the positioning device 3 is a circular leveling plate with a smooth surface, which can ensure a closer and smoother contact with the surface of the cast-in-place floor. The smooth surface reduces the friction with materials such as concrete, so that during the pouring process, the positioning device 3 reduces the impact of concrete flow and improves the control accuracy of the floor thickness.

[0038] Furthermore, when there is a requirement for slope finding during the pouring of the floor slab, the pouring slope of the floor slab can be controlled by setting multiple or multiple groups of devices proposed in this embodiment at different heights.

[0039] The working principle of this embodiment is as follows:

[0040] This embodiment provides a height-adjustable cast-in-place floor thickness control device, which mainly includes a base, a lower adjustment seat, an upper adjustment seat, a connecting piece, a supporting device, a positioning device, etc. The base adopts a regular polygonal mounting base plate design, and a circular array of fixing holes is provided along the center of the base plate to facilitate the device to be firmly fixed on the construction surface.

[0041] The lower adjustment seat is installed on the base and connected to the base by bolts and other fasteners. The lower adjustment seat is provided with a reinforcement channel inside. The channel is in the shape of a truncated cone and has threads inside. The upper adjustment seat is connected to the lower adjustment seat through a connector. The connector can slide in the reinforcement channel to adjust the distance between the upper and lower adjustment seats. A support device is provided above the upper adjustment seat. The device includes a first support plate, a second support plate and a steel bar bracket. The first support plate is connected to the upper adjustment seat, and the second support plate and the first support plate form a T-shaped plate, which enhances the load-bearing capacity of the support device. The steel bar bracket is provided on the support plate to support the steel bar to ensure its position and stability during the pouring process, while ensuring the thickness of the steel bar protective layer so that the steel bar is adequately protected.

[0042] The positioning device adopts a circular leveling plate with a smooth surface, which is installed above the supporting device. The smooth surface of the leveling plate ensures close and smooth contact with the cast-in-place floor slab, reduces the impact of concrete flow during pouring, improves the accuracy and stability of positioning, and further ensures the accuracy of thickness control.

[0043] In addition, an anti-seepage water-stop ring is sleeved on the upper end of the lower adjustment seat. The device is made of anti-seepage material and can prevent water leakage from the floor slab in the later stage and erode the internal reinforced concrete structure.

[0044] In actual construction, first adjust the distance between the upper and lower adjustment seats according to the designed thickness of the floor slab so that the supporting device and the positioning device reach the predetermined height. Then, fix the base to the construction surface through the fixing holes. Next, place the steel bars on the steel bar brackets and cast the floor slab. During the casting process, the positioning device can ensure that the thickness and position of the floor slab are accurate. After the casting is completed, wait for the concrete to solidify, then remove the formwork and cast the next floor slab.
