[0025] The present application embodiment provides a pre-embedded device for a cable trough box through a floor of an electric well, referring to Figures 1 to 4 ,include:

[0026] Embedded box, connecting piece 1, fixing piece 3, including:

[0027] The upper and lower ends of the embedded box are both provided with openings, and the two connecting pieces 1 are respectively connected to the first side wall 6 and the second side wall 7 of the embedded box which are arranged opposite to each other.

[0028] Specifically, the embedded box body may be in a square barrel shape, and has at least four side walls, namely, a first side wall 6 , a second side wall 7 , and a third side wall 8 and a fourth side wall 9 , which are opposite to each other.

[0029] In some embodiments, the embedded box and the corresponding cable trough box are of the same size.

[0030] Specifically, the specific dimensions (length, width, height) of the embedded box are determined according to the actual specifications of the cable trough box and the thickness of the floor plate. The length and width of the embedded box are consistent with the model of the cable trough box. The height of the embedded box is determined according to the actual thickness of the civil floor plate, and the height of the embedded box is consistent with the thickness of the civil floor plate.

[0031] One end of the connecting piece 1 is rotatably connected to one end of the first side wall 6 or the second side wall 7 close to the opening. Two connecting pieces 1 are respectively provided at the upper and lower ends of the embedded box, and connecting holes 4 are opened on the connecting pieces 1.

[0032] In some embodiments, one end of the connecting plate 1 is rotatably connected to the first side wall 6 or the second side wall 7 through a flat-open back thread 2, one end of the back thread 2 is welded to one end of the connecting plate 1, and the other end of the back thread 2 is welded to an end of the first side wall 6 or the second side wall 7 close to the opening.

[0033] Specifically, the foldable connecting piece 1 is welded and connected to the embedded box body by using a flat open back thread 2. When embedded, the connecting piece 1 is folded into the embedded box body, sealed and protected with sealing glue, and taken out from the embedded box body to be connected to the bridge frame during installation. When the cable trough box embedded device is embedded, a hole can be directly opened on the embedded device, and the wire tube that needs to be connected to the bridge frame can be directly connected to the position with a lock buckle during the embedded process.

[0034] In some embodiments, the connection hole 4 is elliptical, and the size of the connection hole 4 matches the connection nut of the cable trough box.

[0035] In some embodiments, the connection hole 4 is 0.5 cm-1.5 cm wide and 7.5 cm-8.5 cm long.

[0036] Specifically, an elliptical connection hole 4 is provided to provide a sufficient adjustable range when connected to the cable trough box, and can be adjusted up and down. The size of the nut connection hole 4 matches the connection nut of the cable trough box.

[0037] One end of the fixing member 3 is connected to the first side wall 6 or the second side wall 7 or the third side wall 8 or the fourth side wall 9 of the embedded box body which is arranged opposite to each other.

[0038] In some embodiments, the fixing member 3 is L-shaped, one end of the L-shaped fixing member 3 is connected to the third side wall 8 or the fourth side wall 9 , and the other end is provided with a fixing hole 5 .

[0039] In some embodiments, there are two fixing members 3, which are respectively arranged on the third side wall 8 and the fourth side wall 9; or,

[0040] There are four fixing members 3 , which are respectively arranged on the first side wall 6 , the second side wall 7 , the third side wall 8 and the fourth side wall 9 .

[0041] Specifically, the L-shaped fixing member 3 can be set at different positions outside the side wall of the embedded box, with a minimum of 2 and a maximum of 4. The specific number and position are determined according to the embedded position conditions on site, and the size of the fixing hole 5 on the L-shaped fixing member 3 is determined according to the type and size of the screw to be fixed, or the fixing hole 5 may not be left, and a pistol drill may be used to drill it during installation.

[0042] When the cable trough box pre-embedded device for electric wells through floor slabs provided in the above embodiment is used, the cable trough box pre-embedded device is customized according to the designed bridge specifications, floor slab thickness and pre-embedded position through the on-site construction drawings. The height of the cable trough box pre-embedded device is determined according to the floor slab thickness, the length and width of the cable trough box pre-embedded device are determined according to the bridge specifications, and the setting position of the cable trough box pre-embedded device fixing part 3 is set according to the favorable fixing point of the on-site pre-embedded position. In this way, the adaptability of the pre-embedded device can be improved.

[0043] Specifically, the design and production process of the pre-buried device for the cable trough box through the floor of the electric well includes:

[0044] (1) Customize the pre-buried cable trough device from the manufacturer according to the model and size of the cable trough box that needs to be installed. The pre-buried cable trough device for the electrical well through the floor slab should be consistent with the model and size of the cable trough box that needs to be installed, and the material should be consistent. The height of the pre-buried device should be the same as the thickness of the floor slab.

[0045] (2) The pre-embedded device of the cable trough box for the electric well through the floor is equipped with two foldable connecting pieces 1 at each end. The connecting pieces 1 are welded to the inner side of the pre-embedded device with a flat open back thread 2. The width of the connecting piece 1 is the same as the inner width of the pre-embedded device and can be folded into the pre-embedded device. The length of each connecting piece 1 is 100 mm, and each connecting piece 1 has an elliptical connecting hole 4 with a width of 1 cm and a length of 8 cm.

[0046] (3) Two fixing plates are added on both sides of the embedded device according to the requirements of the construction site. Screw holes are punched on the fixing plates to facilitate fixing to the formwork with bolts to prevent displacement.

[0047] (4) The floor heights of standard residential floors are all the same, so after the pre-buried device of the cable trough box through the floor slab is completed, the cable trough box is customized according to the floor height. The floor height of civil residential buildings is generally 3m, minus the floor slab thickness of 0.1m, the clearance height between floors is 2.9m, and the length of each section of the customized cable trough box is 2.88m.

[0048] Specifically, the implementation process of the construction technology of the pre-embedded device of the cable trough box through the floor of the electric well includes:

[0049] (1) First, optimize the drawings and determine the layout of the cable trough box in the electrical well according to the actual layout of the equipment inside the electrical well.

[0050] (2) At the first floor construction site, according to the optimized drawings, the cable trough box installation position is first determined on the template. Before positioning, the civil engineering must also cooperate and the electrical well wall line is first laid out. The cable trough box embedded device is fixed to the template with bolts. To prevent displacement, at least two points are fixed. After fixing, the cable trough box embedded device is sealed with sealing glue to prevent concrete from entering.

[0051] (3) To ensure that the same set of cable trough box embedded devices can be embedded in the same vertical line, when embedding the upper layer, it is necessary to use infrared rays to lead two diagonal points from the embedded cable trough box embedded devices of the lower layer to the bottom surface of the upper template, and use a pistol drill to drill two holes in the template at the two leading points. The cable trough box embedded devices of the upper layer are installed and positioned according to the positions of the two holes. The two points are led out from the two points on the diagonal line of the cable trough box embedded devices.

[0052] (4) The floor heights of standard residential buildings are all the same, so after the pre-buried cable trough box device is pre-buried, the bridge is customized according to the floor height. The floor height of a civil residential building is generally 3m, minus the floor plate thickness of 0.1m, and the clearance height between floors is 2.9m. The length of each section of the customized cable trough box is 2.88m, and the length of the cover plate is consistent with the length of the cable trough box.

[0053] (5) After the customized bridge arrives at the site and meets the installation conditions, construction and installation can begin. During installation, the sealing glue of the embedded device of the cable trough box is cleared out, the connecting piece 1 is taken out and connected to the cable trough box with the special bolts of the cable trough box. After the laying of wires and cables is completed, the cable trough box cover is covered and the cable trough box installation is completed.

[0054] In summary, compared with the prior art, the pre-embedded device for cable trough boxes through floor slabs provided by the present application replaces the traditional reserved hole construction method, pre-embeds and forms in one step, eliminates the traditional complicated process, greatly guarantees the quality, improves work efficiency, improves the visual quality of the installation project, and reduces construction costs. The purpose of improving construction efficiency and construction quality is achieved, while achieving the purpose of energy saving, consumption reduction, and green environmental protection. The use of pre-embedded devices for cable trough boxes through floor slabs for electric wells is more unified and standardized, has good economic benefits, and has a wide range of applications.

[0055] Specifically, compared with the prior art, the present application has at least one of the following beneficial effects:

[0056] The cable trough box pre-embedded device for the electric well through the floor slab obtained in the present application avoids the traditional cable trough box reserved hole construction method, pre-embeds and forms in one time, and saves the traditional complicated construction process. The integrity, appearance, standardization and consistency are improved, and the construction quality is guaranteed.

[0057] The present application has a simple structure, is practical, economical, easy to operate, and convenient to install. It can be pre-buried and formed at one time. After the concrete construction is completed, the visual effect is good, and the complex processes such as filling holes and blocking in the later stage are eliminated. The length of the cable trough box in the later stage is customized according to the floor height, which is convenient and quick to install. The cable trough box and the cover plate do not need to be processed secondary during installation due to length issues, and can be directly installed and formed. When pre-buried cable trough boxes and pre-buried devices are pre-buried, holes are drilled in the cable trough box pre-buried devices, and the wire pipes that need to be connected to the bridge are connected in place at one time with locking buckles, eliminating the need to drill holes and secondary piping on the bridge in the later stage, thereby improving the visual quality. It can save labor and material costs to the maximum extent, speed up the construction progress, effectively shorten the project construction period, enhance the construction quality, and greatly promote environmental protection and safe and civilized construction.

[0058] This application can be used not only in standard floor slabs, but also in basements and other places where shear walls and slabs are worn. It is easy and simple to install and fix during pre-embedded construction.

[0059] This application solves and avoids many subsequent problems through one-time pre-embedded molding: (1) It solves the problems of loose and uneven sealing of the bridge openings in the later stage, and improves the visual quality; (2) It avoids the pollution of the finished bridge during the later hole repair; (3) It eliminates all safety problems that may arise when working at heights during the later hole repair; (4) It saves installation time, speeds up the installation progress, and improves the installation quality. This application eliminates the traditional method of reserving holes and uses one-time pre-embedded molding to unify its integrity, appearance, and standardization, ensures the construction specifications and construction quality, reduces construction costs, and has broad practicality and development prospects.
