Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried steel casing fixing, in particular to a pre-buried steel casing fixing structure. Background Art

[0002] In construction projects, the installation of fresh air, air conditioners, heaters, etc. requires pre-buried casings or reserved holes in the building's exterior wall structure. The length of traditional pre-buried casings is only the same as the width of the building's exterior wall structure. The steel casing is shorter, and one end is fixed to the formwork or fixed with wire. During the concrete pouring process, the steel casing will shift due to the vibration of the vibrating pump.

[0003] Based on this, a pre-buried steel casing fixing structure is now provided to eliminate the drawbacks of the existing device. Utility Model Content

[0006] A pre-buried steel casing fixing structure comprises a steel casing, a common template is arranged at the left end of the steel casing, the right end of the steel casing passes through a movable connecting aluminum alloy template and a circular through hole, the lower end of the aluminum alloy template is connected to the right side of the foundation, the lower end of the common template is connected to the left side of the foundation, tension bolts pass through the aluminum alloy template and the common template, the upper end of the middle part of the steel casing is connected to a welding block, the welding block is connected to a welding rib, the upper end of the welding rib is connected to a horizontal wall beam steel bar, the wall beam steel bar is connected to a vertical longitudinal steel bar, and the lower end of the longitudinal steel bar is arranged in the foundation.

[0007] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In an optional solution: a plastic sealing film is provided on the left end surface of the steel casing, and the plastic sealing film is pressed onto the common template by the left end surface of the steel casing.

[0009] In an optional solution, the outer diameter of the steel sleeve matches the diameter of the circular through hole.

[0010] In an optional solution, the welding block is a strip steel plate welded on a steel sleeve.

[0011] In an optional solution: the welded reinforcement is an L-shaped reinforcement welded to the wall beam reinforcement.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model fixes the steel sleeve by welding through L-shaped welding ribs and welding blocks, so that the steel sleeve can maintain a position without deviation when pouring concrete.

[0014] The utility model welds a welding block on the outer wall of the steel casing, welds one end of an L-shaped welding rib on the wall beam steel bar above the steel casing, and the other end of the L-shaped welding rib is close to the surface of the steel casing. The steel casing is rotated to adjust the position of the welding block so that the welding block contacts the welding rib, and then the contact point is welded to fix it. Compared with directly using the L-shaped welding rib to fix the steel casing on the wall beam steel bar, the utility model reduces the operation difficulty and improves the accuracy of burying the steel casing.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] In one embodiment, Figure 1-Figure 4As shown, a pre-buried steel casing fixing structure includes a steel casing 101. A common template 203 is provided at the left end of the steel casing 101, and the right end of the steel casing 101 penetrates the movable connection aluminum alloy template 201 and the circular through hole 202, the lower end of the aluminum alloy template 201 is connected to the right side of the foundation 204, and the lower end of the common template 203 is connected to the left side of the foundation 204, and the tension bolts 205 are penetrated between the aluminum alloy template 201 and the common template 203, and the upper end of the middle part of the steel casing 101 is connected to the welding block 102, and the welding block 102 is connected to the welding rib 103. The upper end of the welding rib 103 is connected to the horizontal wall beam steel bar 206, and the wall beam steel bar 206 is connected to the vertical longitudinal steel bar 207. The lower end of the longitudinal steel bar 207 is set in the foundation 204. After the steel sleeve 101 is inserted between the aluminum alloy template 201 and the ordinary template 203 through the circular through hole 202, the welding block 102 is welded to the outer wall of the steel sleeve 101, and the welding rib 103 is welded to the wall beam steel bar 206. After the steel sleeve 101 is rotated to make the welding block 102 contact the welding rib 103, the welding contact point is fixed.

[0022] In one embodiment, Figure 1 As shown, the left end face of the steel casing 101 is provided with a plastic sealing film, and the left end face of the steel casing 101 presses the plastic sealing film onto the common formwork 203 to prevent concrete from flowing into the interior of the steel casing 101 from the gap between the steel casing 101 and the common formwork 203 .

[0023] In one embodiment, Figure 1 and Figure 3 As shown, the outer diameter of the steel casing 101 matches the diameter of the circular through-hole 202 , preventing the concrete slurry from flowing out from the gap between the steel casing 101 and the circular through-hole 202 .

[0024] In one embodiment, Figure 3 and Figure 4 As shown, the welding block 102 is a strip steel plate welded on the steel sleeve 101 , and the position of the welding block 102 can be adjusted by rotating the steel sleeve 101 .

[0025] In one embodiment, Figure 3 and Figure 4 As shown, the welding rib 103 is an L-shaped steel bar welded to the wall beam steel bar 206.
