Description

Technical Field

[0001] The utility model relates to an embedded box, in particular to an embedded box for a template that does not require disassembly. Background Art

[0002] In the traditional construction of pre-embedded wire boxes, it is usually necessary to first punch holes in the template, and then use wire ties to fix the pre-embedded wire box for construction on the template. After the concrete is poured, the template is removed, leaving the pre-embedded box on the building structure. However, after the construction using the non-disassembly template, since the non-disassembly template does not need to be removed after the concrete is poured, the installation hole is opened on the non-disassembly template. The gap between the installation hole and the existing embedded box is difficult to ensure sealing. When pouring concrete, it is easy to form concrete leakage and sagging, which affects the appearance of the non-disassembly template. In order to prevent the slurry from entering the wire box, it is necessary to wrap and fill the wire box before embedding, and the slurry entering the embedded box and the wrapping and filling materials before embedding need to be cleaned after pouring. In addition, since the thickness of the non-disassembly template has a variety of specifications, for the traditional embedded box with a fixed depth, it is impossible to adapt to the non-disassembly template of different thicknesses, so that the terminal box port is flush with the outer side of the non-disassembly template, and the installation quality of the embedded wire box cannot be guaranteed. Utility Model Content

[0003] The utility model aims to provide an embedded box for a non-disassembly formwork, so as to solve the problems that the existing traditional embedded boxes are prone to leakage and the installation quality cannot be guaranteed when used for the non-disassembly formwork.

[0015] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model is an embedded box for a non-disassembly template 1, mainly comprising a bottom box 2, a telescopic joint 3 and an adjustment mechanism. The bottom box 2 is a tubular structure with an opening at one end, the telescopic joint 3 is a tubular structure with openings at both ends, the telescopic joint 3 is located in the bottom box 2, and the telescopic joint 3 and the bottom box 2 are slidably connected, a wing plate 4 extending outward around the open end of the bottom box 2 is provided, and an adjustment mechanism is provided between the telescopic joint 3 and the bottom box 2, and the adjustment mechanism is used to adjust the length of the telescopic joint 3 extending outward from the open end of the bottom box 2.

[0017] The adjusting mechanism includes an adjusting bolt 6 and an adjusting nut 7. The adjusting bolt 6 is connected to the telescopic joint 3, and the adjusting nut 7 is fixed on the bottom box 2. The telescopic joint 3 is driven to telescopically slide in the bottom box 2 by rotating the adjusting bolt 6, thereby adjusting the length of the telescopic joint 3 extending outward from the opening end of the bottom box 2.

[0018] Specifically, a through-connection portion 11 is provided on the outer side of the outer port of the telescopic joint 3, a through-connection hole is opened on the through-connection portion 11, a fixing portion 12 is provided on the side wall of the bottom box 2, an adjusting nut 7 is embedded and fixed on the fixing portion 12 and is coaxial with the through-connection hole, an adjusting bolt 6 is threadedly connected with the adjusting nut 7 after passing through the through-connection hole, and the adjusting bolt 6 passes through the fixing portion 12, and at the same time, a clamping ring 8 is fixedly provided on the adjusting bolt 6, the through-connection portion 11 is located between the clamping ring 8 and the bolt head of the adjusting nut 7, and the clamping ring 8 is used to limit the relative movement between the adjusting bolt 6 and the through-connection portion 11 along the axial direction. In this way, when the adjusting nut 7 is rotated, the telescopic length of the telescopic joint 3 can be adjusted.

[0019] Furthermore, a concave slide groove 9 is provided on the outer side surface of the side walls of both sides of the telescopic joint 3, and a sliding structure 10 cooperating with the slide groove 9 is provided on the side walls of both sides of the bottom box 2. The sliding structure 10 is located in the slide groove 9, and the sliding structure 10 cooperates with the slide groove 9 to guide the movement of the telescopic joint 3. Among them, the fixing part 12 is located on the sliding structure 10, and the connecting part 11 is located at the end of the slide groove 9.

[0020] Furthermore, the sliding structure 10 is a U-shaped structure formed by the inward concave side wall of the bottom box 2 , and the inner side surface of the U-shaped structure contacts the surface of the slide groove 9 .

[0021] In order to ensure that the port of the expansion joint 3 can be completely flush with the outer side of the non-disassembly formwork 1, a countersunk hole is provided in the connecting portion 11, and the bolt head of the adjusting bolt 6 is located in the countersunk hole, which can prevent the adjusting bolt 6 from protruding from the outer side of the non-disassembly formwork 1.

[0022] The surface of the wing plate 4 is flush with the open end of the bottom box 2. The wing plate 4 can be connected to the pre-removed template by self-tapping screws. A plurality of through holes 5 are opened on the wing plate 4. Generally, there are four through holes 5, and the four through holes 5 are located at the four corners of the bottom box 2. When the bottom box 2 is fixedly connected to the non-removal template 1, the self-tapping screws are inserted into the through holes 5, and the self-tapping screws are inserted into the non-removal template 1 and tightened, so that the surface of the wing plate 4 is closely fitted with the inner side of the non-removal template 1.

[0023] Since the existing pre-buried wire boxes are all rectangular, the outlines of the bottom box 2, the telescopic joint 3 and the wing plate 4 of the utility model are also rectangular.

[0024] The utility model is a pre-buried wire box specially used for the non-disassembly template 1. When the pre-buried wire box is constructed, the process is as follows: according to the design requirements, a pre-buried box hole is opened at the corresponding position on the non-disassembly template 1, and the size of the pre-buried box hole is consistent with the outline size of the expansion joint 3; according to the thickness of the non-disassembly template 1, the adjusting bolt 6 is rotated to make the length of the expansion joint 3 exposed from the port of the bottom box 2 equal to the thickness of the non-disassembly template 1; the utility model is placed into the pre-buried box hole from the inner side of the non-disassembly template 1, and the self-tapping screw is inserted into the through hole 5 on the wing plate 4 to fix the bottom box 2 of the utility model on the non-disassembly template 1. After tightening the self-tapping screw, the wing plate 4 and the non-disassembly template 1 can be closely fitted to form a sealing surface, which can effectively prevent leakage of slurry at the pre-buried box hole during subsequent concrete pouring, and can ensure the cleanliness of the inside of the wire box, so that the subsequent construction can be carried out directly.
