Technical Field
[0001] The utility model relates to the field of building construction tools, in particular to a pre-embedded fixing device for cantilevered I-beams in building construction. Background Art
[0002] On construction sites, cantilever I-beams are often required for the construction and protection of special parts and wall facades. Cantilever I-beams are embedded and fixed as pre-embedded parts. They are disposable and are usually cut off directly when the embedded parts are removed. They cannot be recycled. Since there are a large number of cantilever I-beams embedded in the exterior walls of buildings, the consumption of a large number of cantilever I-beams greatly increases the construction cost.

[0004] The technical solution is as follows:
[0005] The embedded fixing device for cantilevered I-beams in construction includes: a first connecting plate, a sleeve, a screw, and a second connecting plate; the first connecting plate is provided with a plurality of first connecting through holes, the screws are fixedly connected in the first connecting through holes, and the screws are sleeved with sleeves; the second connecting plate is provided with a plurality of second connecting through holes, the upper part of the screws is passed through the second connecting through holes, a gasket and a nut are installed at the top of the screws, and the second connecting plate is located at the upper part of the sleeve.
[0006] Furthermore, the first connecting plate and the second connecting plate are rectangular steel plates, the first connecting plate is connected to two screw rods, and the second connecting plate is provided with two second connecting through holes.
[0007] Furthermore, a gasket and two nuts are connected to the upper end of the screw rod. The gasket is rectangular in shape, and a spring washer is arranged under the gasket.
[0008] Furthermore, the screw is connected in the first connecting through hole by double-sided full welding.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] The embedded parts for the construction of cantilever I-beams are simple and compact in design, cheap in cost, and can effectively avoid the waste of cantilever I-beams in the construction of the wall facade. The cantilever I-beams can be effectively recycled, and are suitable for promotion and use on construction sites. When the embedded parts for the construction of cantilever I-beams can be used, the embedded parts can be fixed at a specified position before pouring concrete, a sleeve can be put on the outside of the screw, and the screws can be poured together in the concrete during the pouring of concrete. When the concrete strength reaches the design value, the cantilever I-beam is fixed at the specified position of the concrete, and the front and rear ends of the cantilever I-beam are fixed by the screws, pressing sheets and nuts on the top of the embedded parts. After the cantilever I-beam is removed, the embedded parts can be partially recycled by manual labor and reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a structural schematic diagram of the second connecting plate in the utility model. DETAILED DESCRIPTION
[0013] The following description sufficiently illustrates specific embodiments of the present invention to enable those skilled in the art to practice and reproduce the same.
[0014] like Figure 1 As shown, it is a structural schematic diagram of the pre-embedded fixing device of the cantilever I-beam in the construction of the utility model; Figure 2 The figure is a schematic diagram of the structure of the second connecting plate in the present invention.
[0015] The embedded fixing device for cantilevered I-beams in construction comprises: a first connecting plate 1, a sleeve 2, a screw 3, and a second connecting plate 4; the first connecting plate 1 is provided with a plurality of first connecting through holes, a plurality of screws 3 are respectively installed in the plurality of first connecting through holes, the screws 3 are connected in the first connecting through holes by double-sided full welding, the first connecting plate 1 is connected to the screws 3, and the screws 3 are sleeved with the sleeve 2; the second connecting plate 4 is provided with a plurality of second connecting through holes 7, the upper part of the screws 3 is penetrated in the second connecting through holes 7, a gasket 5 and a nut 6 are installed at the top of the screws 3, and the second connecting plate 4 is located at the upper part of the sleeve 2.
[0016] In the preferred embodiment, the first connecting plate 1 and the second connecting plate 4 are rectangular steel plates. The first connecting plate 1 is connected to two screw rods 3 , and the second connecting plate 4 is provided with two second connecting through holes 7 .
[0017] A washer 5 and two nuts 6 are connected to the upper end of the screw rod 3 to strengthen the connection strength between the second connecting plate 4 and the screw rod 3. The washer 5 is rectangular in shape, and a spring washer may also be provided under the washer to improve impact resistance.
[0018] The rectangular steel plate 1, the screw rod 3, the rectangular steel plate 4, the rectangular steel plate gasket 5, and the nut 6 are all made of Q345 steel, which is durable and has good corrosion resistance. The casing 2 is made of PVC pipe, which is soft and has good elasticity. It is not easy to break after being stressed, and is suitable for use on construction sites.
[0019] When construction is required at special parts of a building or on the facade of a wall, or when protective construction is required later, the first connecting plate 1 is pre-buried at a designated position, and the screw 3 is located outside the concrete. After the concrete solidifies, if the cantilever I-beam is wide, multiple fixing holes can be pre-set on the cantilever I-beam, and the screw 3 passes through the fixing holes and is fixed with a gasket 5 and a nut 6. Then the cantilever I-beam can be used to build a walking passage, which is convenient for walking, construction and maintenance on the facade of the wall.
[0020] If the width of the cantilevered I-beam is narrow, the end of the cantilevered I-beam can be placed between two screw rods 3 and then fixed with a gasket 5 and a nut 6.
