[0011] The present invention provides a construction device for reserved holes for water, electricity and heating in residential buildings. It has the following beneficial effects:

[0012] The invention relates to a construction device for pre-installed holes for water, electricity and heating in residential buildings. The pre-installed pipes are composed of a positioning mechanism, an arc plate and a rubber plate. The positioning mechanism is sleeved in the movable groove so that the limiting disc is located above the I-shaped plate. The rotating handle is manually rotated to make the sleeve shaft screw and fix the supporting device, and the through hole on the limiting disc corresponds to the first positioning hole. The positioning pin is then inserted into the through hole of the limiting disc and the first positioning hole, so that the pre-installed pipe composed of the arc plate and the rubber plate is installed in the required position, and the positioning pin can be inserted into different first positioning holes as needed to adjust the position of the pre-installed pipe, which plays a role in positioning and can also fix rows of pre-installed pipes to obtain rows of pre-installed holes. It can ensure the accuracy of the positioning of the rows of pipes and can also control the distance of the pre-installed holes by controlling the distance of the pre-installed pipes as needed, thereby solving the problem that the traditional pre-installed hole construction cannot accurately ensure the accuracy of the position of the rows of pre-installed holes.

[0013] 2. The construction device of the reserved hole for water, electricity and heating in the house is used. The fixed vertical rod is screwed and fixed in the sleeve shaft through the supporting device, and the positioning rod is stuck in one of the grooves of the connecting side block. The lower the groove where the positioning rod is stuck, the greater the extrusion force exerted by the positioning rod on the connecting side block. With the elastic cooperation of the rubber plate, the diameter of the reserved hole can be slightly adjusted, which is convenient for a certain fault tolerance when installing water, electricity and heating pipes, and also convenient for the subsequent work of the staff. After the reserved pipe is placed, concrete is poured around it. The reserved pipe is squeezed by the concrete, and the positioning mechanism is slightly rotated downward, so that the fixed vertical rod drives the connecting plate to move downward, and the inclined plate pushes the positioning rod to both sides. The connecting side block is squeezed to push the arc plate outward to prevent the reserved pipe from being damaged by excessive pressure, thereby playing a protective role.

[0014] 3. The construction device for the reserved holes for water, electricity and heating in residential buildings uses a stabilizing device to fix the curved sleeve on the outer surface of the curved plate through a fixing mechanism. After the concrete is poured, the curved sleeve is squeezed outward by the supporting device. Under the squeezing of the supporting device and the concrete, the air inside the curved sleeve is squeezed out, and the curved sleeve is in a negative pressure state. As the concrete solidifies, the moisture in the concrete is lost, the volume of the concrete decreases, and at the same time, the cavity outside the curved sleeve increases. The positioning mechanism is used to move the supporting device downward, so that the curved plate is squeezed to both sides to make the curved sleeve fit more closely to the concrete, thereby improving the degree of fit between the curved sleeve and the concrete by increasing the contact area and the internal and external air pressure, avoiding loosening of the reserved pipe due to the solidification of the concrete, preventing large changes in the position of the reserved pipe, and further improving the accuracy of the reserved hole position.

[0015] 4. The construction device for the reserved hole for water, electricity and heating in the house is fixed by the fixing mechanism. First, the fixing bolts are passed through the fixing holes of the arc plate and the curved sleeve plate to fix the sleeve shell and the curved sleeve plate on the arc plate. After the fixing bolts are screwed inward to fix them with the magnetic column, they are pushed inward to make the magnetic column gradually slide into the sleeve shell until it is completely retracted into the sleeve shell to prevent the concrete from solidifying the exposed magnetic column and affecting subsequent operations. Since the magnetic column and the magnetic rotating plate repel each other with the same polarity, the magnetic rotating plate opens outward, increasing the contact area with the concrete, which is beneficial to improving the entire reserved pipe To ensure the stability of the pipe, when the concrete is completely solidified, loosen the fixing bolts, take out the entire reserved device by lifting the handle, and leave the shell in the concrete, put the water, electricity and heating pipes into the reserved hole, the magnetic column moves inward, and the telescopic rod is shortened under force, so that the bending plate and the spring are squeezed and force is stored. When the water, electricity and heating pipes are completely put in, the elasticity of the bending plate and the spring exerts extrusion force on the outer wall of the water, electricity and heating pipes, which is convenient for the installation and fixation of the water, electricity and heating pipes. It not only facilitates the construction of the reserved hole, but also provides convenience for the subsequent installation of water, electricity and heating pipes, thereby improving work efficiency.

[0034] Example 3

[0035] like Figure 5-Figure 7 As shown, the stabilizing device 9 includes a curved sleeve 91, the outer surface of the curved sleeve 91 is arranged on the outer surface of the curved plate 7, the outer surface of the curved sleeve 91 is provided with a through groove 93, the number of the through grooves 93 is several, the interior of the curved sleeve 91 is provided with a fixing mechanism 92, the outer surface of the fixing mechanism 92 passes through the curved plate 7, and the outer surface of the curved sleeve 91 is movably connected to the outer surface of the curved plate 7 through the fixing mechanism 92.

[0036] The fixing mechanism 92 includes a casing 921 , and a magnetic rotating plate 922 is rotatably connected to the outer surface of the casing 921 . The number of the magnetic rotating plates 922 is several.

[0037] The inner surface of the housing 921 is slidably connected to a magnetic column 923 , the internal thread of the magnetic column 923 is connected to a fixing bolt 924 , the outer surface of the fixing bolt 924 passes through the arc plate 7 , and the end of the magnetic column 923 away from the fixing bolt 924 is fixedly connected to a telescopic rod 928 .

[0038] The output end of the telescopic rod 928 is fixedly connected to a cylindrical block 925, the outer surface of the cylindrical block 925 is fixedly connected to the inner surface of the sleeve 921, the outer surface of the cylindrical block 925 is fixedly connected to a bending plate 926, the outer surface of the bending plate 926 is fixedly connected to the outer surface of the telescopic rod 928, the outer surface of the bending plate 926 is fixedly connected to a spring 927, the end of the spring 927 away from the bending plate 926 is fixedly connected to the end of the magnetic column 923, and the outer surface of the spring 927 is sleeved on the outer surface of the telescopic rod 928.

[0039] When in use, the curved sleeve 91 is fixed to the outer surface of the curved plate 7 through the stabilizing device 9 and the fixing mechanism 92. After the concrete is poured, the curved sleeve 91 is squeezed outward by the supporting device 6. Under the squeezing of the supporting device 6 and the concrete, the air inside the curved sleeve 91 is squeezed out, and the curved sleeve 91 is in a negative pressure state. As the concrete solidifies, the moisture in the concrete is lost, the volume of the concrete decreases, and at the same time, the cavity outside the curved sleeve 91 increases. The supporting device 6 is moved downward by the positioning mechanism 5, so that the curved plate 7 is squeezed to both sides to make the curved sleeve 91 fit more closely to the concrete, thereby improving the degree of fit between the curved sleeve 91 and the concrete by increasing the contact area and the internal and external air pressure, avoiding the loosening of the reserved pipeline due to the solidification of the concrete, preventing the position of the reserved pipeline from changing significantly, and further improving the accuracy of the reserved hole position.

When the concrete is completely solidified, loosen the fixing bolts 924, take out the entire reserved device by lifting the handle 3, and leave the shell 921 in the concrete. Put the water, electricity and heating pipe into the reserved hole, and the magnetic column 923 moves inward.
