Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a method for pre-embedded construction of a switch socket electrical bottom box. Background Art

[0002] In recent years, demands for fully decorated homes have emerged across the country. There are multiple considerations behind the implementation of fine-decoration delivery, including policy guidance, market demand, and the implementation of environmental protection concepts.

[0003] First, from a policy perspective, it is clearly stated that the development of finished houses should be accelerated to improve housing quality. The purpose is to adapt to the improvement of people's economic level and the requirements for living environment, so that people can choose finished houses that are easy to use, labor-saving and money-saving, and can be moved in with just a bag. Secondly, in terms of market demand, with the continuous development of the real estate market, consumers have higher and higher requirements for the quality and convenience of housing. Fine decoration delivery can meet consumers' needs for a one-stop home buying experience and reduce the troubles and time costs of decoration after buying a house. Finally, the implementation of environmental protection concepts is also an important consideration for fine decoration delivery. Some fine decoration projects fully implement the ecological, environmental protection, and green development concepts during the design and construction process, and reduce the negative impact on the environment and improve the environmental performance of housing by adopting green building materials, energy-saving equipment and other measures.

[0004] In order to meet the standards of fine decoration delivery, higher quality requirements are placed on the accuracy of the reserved and embedded electrical boxes of switches, sockets and electrical boxes during the main building construction process.

[0005] At present, during the construction of the main building, the switch socket electrical bottom box is located at the column or shear wall. It needs to be pre-buried and installed before pouring concrete during structural construction, and the finished product must be well protected. The construction process of the switch socket electrical bottom box here is as follows: 1. Chisel and clean the concrete on the slab surface; 2. Clean the short pipes of the reserved wire pipes on the floor surface, remove the sealing tape on the pipe heads of the short pipes, and remove the pipe plugs inside; 3. Measure and draw lines, and position the height lines of the switches and sockets on the design drawings on the steel bars; 4. Knock out the knockout holes on the electrical bottom box of the switches and sockets and install the pipe joints, fill the bottom box with foam blocks and seal it with tape to prevent the concrete slurry from flowing in; 5. Cut the short pipes of the required length according to the height of the lines and the length of the reserved pipes on the slab surface, and connect the short pipes to the pipe joints on the electrical bottom box and the short pipes of the reserved wire pipes on the slab surface; 6. Fix the electrical bottom box of the switches and sockets connected with the pipes to the steel bars of the wall columns by steel wire tying; 7. According to the thickness of the wall columns, make and cut short steel bars of corresponding lengths as positioning steel bars, and weld the positioning steel bars in the middle of the front and rear templates as reinforcement support to prevent the electrical bottom box from shifting due to the swing of the steel bars; 8. Release the edge lines of the wall columns along the ground, seal the templates around the wall columns, and pour concrete.

[0006] The following problems exist in the construction process of pre-buried switch and socket electrical bottom box: 1. Stuff the foam block in the bottom box and seal it with tape to prevent the concrete slurry from flowing in. This method costs a lot of manpower and materials, and it will take a lot of manpower to clean it up after the formwork is removed later; 2. Even if the bottom box is filled with foam and sealed with tape, when the vibrator vibrates on the electrical bottom box during concrete pouring, the pipe joints are prone to breakage, leakage and pipe blockage; 3. Tie the electrical bottom box to the wall column reinforcement and weld the positioning reinforcement to prevent it from shifting. This method can effectively prevent the pre-buried electrical bottom box from shifting for wall columns with a thickness greater than 200mm and double-sided reinforcement. However, in the case of single-row reinforcement, the welded positioning reinforcement cannot achieve effective fixation, and a large number of electrical bottom boxes on site are shifted.

[0007] 4. When fixing by welding, on-site electric welding operations are prone to fire and pose a safety hazard. Summary of the invention

[0008] The purpose of the present invention is to solve the problems of pre-embedded deviation, pipe leakage and pipe blockage, and the need for hot work in the current construction process of pre-embedded construction of switch socket electrical base boxes. The present invention provides a pre-embedded construction method for switch socket electrical base boxes, aiming to avoid on-site hot work and reduce the risks of pre-embedded deviation and pipe leakage and pipe blockage.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows.

[0010] A method for pre-embedded construction of a switch socket electrical bottom box, the method comprising the following steps: A. Chisel and lay out the wires and tie the steel bars; B. Clean the pipe opening; C. Seal one side of the formwork; D. Measure and draw lines; E. Open holes in the aluminum formwork; F. Lock the electrical bottom box; G. Connect the pipes; H. Seal the remaining formwork; I. Pour concrete; J. Remove the formwork; The electrical bottom box is provided with pipe interfaces at both ends, and knock-out holes are preset at the pipe interfaces; The step I is to pour concrete into the constructed formwork when pouring concrete.

[0011] Preferably, the step A is to roughen and clean the slab surface concrete, lay out the edge lines of the wall columns on the ground, and tie the wall column reinforcements.

[0012] Preferably, the step B is to clean the short pipe of the electrical wire pipe reserved on the floor surface, remove the sealing tape on the head of the short pipe, and remove the pipe plug inside.

[0013] Preferably, the step C is to fix and seal the aluminum template on the wall where the switch socket is located, and the size and structure of the aluminum template used are determined by the design drawings.

[0014] Preferably, the step D is to draw lines to locate the position of the switch socket electrical base box on the design drawing on the aluminum template.

[0015] Preferably, the step E is to drill holes on the aluminum template with a twist drill according to the spacing of the four fixing holes on the electrical bottom box.

[0016] Preferably, the step F is to align the four fixing holes of the electrical bottom box with the four holes on the aluminum template, and use self-tapping screws to penetrate the template holes from the outside and drill into the fixing holes of the electrical bottom box to lock the electrical bottom box on the aluminum template.

[0017] Preferably, step G is to knock off the knockout hole plate at the position where the pipe needs to be connected on the electrical base box to expose the pipe interface, and cut the wire pipe to extend it according to the actual length of the pipe reserved from the electrical base box to the ground; the wire pipe connected to the electrical base box is directly inserted into the inside of the wire box and a certain length margin is left to facilitate the aluminum mold to adjust the gap, and the wire pipe head inserted into the electrical base box is sealed with a pipe plug.

[0018] Preferably, the step H is to fix the remaining surface templates along the edge lines on the ground.

[0019] Preferably, in step J, after the concrete reaches a certain strength, the self-tapping screws on the formwork are first removed, and then the formwork is disassembled.

[0020] Compared with the existing construction method, the method of the present invention directly locks the switch socket electrical bottom box on the aluminum template to avoid the risk of deviation during concrete pouring. After the template is removed, the bottom box is completely attached to the template and pre-buried in one step, reducing the cost of secondary chiseling. No hot work is required, which reduces the fire hazard. There is no need for direct head connection between the wire pipe and the electrical bottom box, which reduces the interface and reduces the risk of leakage and pipe blockage during vibration.
