[0023] like Figures 1 to 4 As shown, the present application provides a floor thickness control and wire pipe positioning device, including a first support assembly 1, a vertical rod 5, a wire pipe positioning assembly and a second support assembly, wherein the first support assembly 1 is installed on the floor surface; the vertical rod 5 is connected to the end of the first support assembly 1 away from the floor; the wire pipe positioning assembly includes a first sleeve 2 and a positioning member 6, the first sleeve 2 is sleeved on the vertical rod 5 and is snap-connected with the first support assembly 1, the positioning member 6 is vertically arranged on the first sleeve 2 for supporting the wire pipe; the second support assembly is arranged on the upper part of the vertical rod 5.

[0024] Specifically, the first support assembly 1 is directly placed on the floor surface to support the entire floor thickness control and wire pipe positioning device. The bottom steel mesh is fixed to the first support assembly by binding, so as to ensure that the bottom steel mesh can obtain sufficient stability and support force. The vertical rod 5 is firmly connected to the first support assembly 1 by threaded connection, welding or special fasteners to ensure stability in the vertical direction and avoid any shaking. The first sleeve 2 is sleeved on the vertical rod 5, and its diameter is larger than the inner diameter of the vertical rod 5. Its connection method is practical and flexible. The sleeve can be installed at the position where the wire pipe is not required, which can effectively reduce the cost. Through the sliding or locking mechanism (such as screws, buckles) and the vertical rod 5, it is tightly matched to achieve flexible adjustment while maintaining stability. The positioning member 6 is vertically fixed to the outer wall of the first sleeve 2 and is directly used to support the wire pipe. Its structure can be a fixed bracket or a slot to ensure that the wire pipe can be accurately fixed in a predetermined position to avoid displacement during concrete pouring. The second support assembly is located on the upper part of the vertical rod 5, and the surface steel mesh is fixed to the second support assembly by binding, so as to ensure that the surface steel mesh can obtain sufficient stability and supporting force.

[0025] The above technical solution adopted by the floor thickness control and wire tube positioning device provided in the present application can achieve the following beneficial effects:

[0026] By setting the first support assembly 1, the vertical rod 5, the second support assembly, the first sleeve 2 and the positioning piece 6, the first sleeve 2 is connected to the first support assembly 1 by snapping, ensuring that the positioning piece 6 vertically installed on the first sleeve 2 is stable and does not shake, so that the installation of the wire pipe on the positioning piece 6 becomes firm, further strengthening the stability of the wire pipe, and effectively preventing the displacement of the wire pipe during concrete pouring, thereby greatly improving the crack resistance of the concrete structure and ensuring the construction quality and safety; the first sleeve 2 is installed in the middle of the vertical rod 5 in a sleeve manner, and the direction can be adjusted by rotating the first sleeve 2 according to the buried path of the wire pipe; through the hierarchical layout of the upper (second support assembly), middle (first sleeve 2 and positioning piece 6), and lower (first support assembly 1), it is ensured that the wire pipe can be securely It is placed between two layers of steel mesh to maintain a certain distance between the wire tube and the steel bar, avoiding the interference caused by direct contact between the wire tube and the steel bar, which may affect the normal arrangement and anchoring of the steel bar, and at the same time reduce the weakening of the concrete cross-section in the multi-wire tube gathering area, reduce the risk of stress concentration, promote uniform pouring of concrete, and improve the bearing capacity and crack resistance of the floor slab; the first support assembly 1 is directly placed on the floor slab surface to support the entire floor slab thickness control and wire tube positioning device, and the bottom layer of steel mesh is fixed to the first support assembly 1 by binding, so as to ensure that the bottom layer of steel mesh can obtain sufficient stability and supporting force; the second support assembly is arranged on the upper part of the vertical rod 5, which is used to bear the surface steel mesh, and echoes the first support assembly 1 up and down to jointly construct a three-dimensional support system for the steel mesh.

[0027] In one embodiment, a notch 21 is provided at the lower portion of the first sleeve 2 , and the first sleeve 2 is engaged with the first supporting assembly 1 via the notch 21 .

[0028] Specifically, the lower part of the first sleeve 2 is provided with a plurality of slots 21 matching the first support assembly 1. During installation, the slots 21 are inserted into the first support assembly 1 for snap connection, so that the first sleeve 2 does not rotate, and plays a role in fixing and positioning the pre-buried wire tube, and can resist external force impact and vibration from all sides, prevent the wire tube from shifting or sinking, and ensure the correct layout of the electrical pipeline. The slot 21 and the snap connection design simplify the on-site installation steps, and facilitate the on-site construction personnel to quickly complete the assembly and adjustment of the positioning assembly without complicated tools or techniques, which greatly improves the construction efficiency and reduces the possibility of operation errors.

[0029] In one embodiment, one end of the positioning member 6 away from the first sleeve 2 is bent upward.

[0030] Specifically, the positioning member 6 is made of a high-strength metal strip, one end of which is fixed to the first sleeve 2 by welding, threaded connection or special fasteners, and the end away from the first sleeve 2 is bent upward, which not only reserves a physical installation space for the wire pipe, but also allows the bending angle and height to be adjusted according to the diameter and layout requirements of the wire pipe. During the installation process, the wire pipe is tightly and safely tied to the bend of the metal strip with iron wire, which enhances the stability of the wire pipe in the vertical hanging state and avoids the problem of cracks in the concrete casting layer that may be caused by accidental displacement or falling of the wire pipe.

[0031] In one embodiment, the second supporting assembly includes a second sleeve 3 and a supporting member 4 , the second sleeve 3 is detachably connected to the upper portion of the vertical rod 5 , and the supporting member 4 is disposed on the peripheral side of the second sleeve 3 .

[0032] Specifically, the second support assembly includes a second sleeve 3 and a support member 4, wherein the second sleeve 3 is detachably connected to the upper part of the vertical rod 5, and can adopt mechanisms such as threaded connection, snap-on design, pin fit or quick-release joints, so that operators can easily install or remove the second sleeve 3, and the distance between the support member 4 and the top of the vertical rod 5 can be adjusted to meet the different concrete protective layer thicknesses above the surface steel mesh. The support member 4 is vertically fixed to the outer wall of the second sleeve 3, which may be achieved by welding, bolting, plugging or specially designed fasteners to ensure that it is firmly connected to the second sleeve 3, so as to provide the necessary support force for the surface steel mesh. The specific form of the support member 4 (such as a beam, bracket, etc.) will be determined according to the actual application requirements.

[0033] Based on the above technical solution, the second supporting assembly further includes a limiting plate 7, which is arranged on the vertical rod 5, and the second sleeve 3 cooperates with the limiting plate 7 in limiting position in the gravity direction.

[0034] Specifically, the stopper 7 is mounted on the vertical rod 5, and is usually firmly attached to a specific part of the vertical rod 5 by welding, screw fixing or snapping, etc., to ensure that it is stable and does not shift. The cross-sectional size of the stopper 7 is smaller than the inner diameter of the first sleeve 2, so that the first sleeve 2 can be smoothly inserted into the vertical rod 5, and at the same time larger than the inner diameter of the second sleeve 3, ensuring that the second sleeve 3 can be firmly placed on the stopper 7. Such a design not only ensures the coordinated assembly between the components, but also maintains the portability of the assembly.

[0035] In one embodiment, the support member 4 is overlapped on the upper end of the first sleeve 2 .

[0036] Specifically, in some cases, in order to reduce costs, a simpler method can be adopted to install the second sleeve 3, that is, not relying on the limit plate 7. The length of the first sleeve 2 is extended, and the supporting member 4 matched with the second sleeve 3 is directly overlapped to the upper end of the first sleeve 2, eliminating the use of the limit plate 7. By abandoning the use of the limit plate 7, the need for additional parts is directly reduced, thereby reducing material costs.

[0037] In a more preferred embodiment, the second sleeve 3 and the vertical rod 5 are threadedly connected.

[0038] Specifically, during the concrete pouring process, considering the influence of external forces, the second sleeve 3 may rotate regardless of whether it is installed on the stopper 7 or the support member 4 is overlapped on the upper end of the first sleeve 2, which will directly affect the accuracy of its predetermined position. Therefore, the second sleeve 3 and the vertical rod 5 are connected by threaded connection, which enhances the mechanical engagement between the two, significantly improves the torsion resistance, and effectively prevents the second sleeve 3 from rotating during construction.

[0039] In one embodiment, the support member 4 includes an upper bending support frame, which is vertically arranged on the second sleeve 3 and has one end away from the second sleeve 3 bent upward at a right angle.

[0040] Specifically, the support member 4 includes an upper bending support frame, which is composed of four high-strength metal bars, one end of which is fixed to the second sleeve 3 by welding, threaded connection or special fasteners, and the end away from the second sleeve 3 is bent upward, which reserves a physical installation space for the steel bars on the surface steel mesh. During the installation process, the steel bars are tied to the metal bars with iron wire to avoid cracks in the concrete casting layer caused by accidental displacement of the steel bars.

[0041] In one embodiment, the first support assembly 1 comprises a buckle support frame, and one end of the buckle support frame away from the vertical rod 5 is bent downward at a right angle.

[0042] Specifically, the first support assembly 1 includes a buckle support frame, which is a cross frame composed of four high-strength metal bars, which are built perpendicular to each other. One end of the metal bar is fixed to the second sleeve 3 by welding, threaded connection or special fasteners, and the end away from the second sleeve 3 forms a downward bending shape to ensure stable contact and support with the floor surface. The steel bars on the bottom steel mesh are tied to the metal bars by wire to avoid the problem of cracks in the concrete casting layer caused by accidental displacement of the steel bars.

[0043] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application should be based on the attached claims.
