Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a lintel sleeve which is installed without welding. Background Art

[0002] The traditional lintel sleeve fixed installation construction process is to place the sleeve inside the beam first. In order to ensure good fixation of the sleeve, special operations personnel are arranged to weld the sleeve to the steel bars at the same time, which makes the installation more cumbersome.

[0003] The existing casing pre-embedding process directly welds the casing on the structural beam 4. The construction workers must wear electric welding machines for pre-embedding, and the horizontality of the casing is not well controlled. At the same time, welding damages the performance of the structural beam 4, the casing has poor stability, and the distance between the pre-embedded casing and the top plate cannot be adjusted according to the size of the structural beam 4, which makes the later installation of the machine very inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a lintel sleeve that is simple in design and easy to operate, can make the pre-buried height of the sleeve more accurate, and at the same time, does not cause shaking during the pouring process by using dovetail nails for fixing, and can also be suitable for welding-free installation of pre-buried sleeves of different specifications and sizes.

[0005] The utility model is achieved through the following measures:

[0006] A lintel sleeve for welding-free installation, characterized in that it comprises a fixed support plate of the sleeve, characterized in that threaded holes are provided at both ends of the fixed support plate, and the threaded holes are used for fixing dovetail nails and aluminum films;

[0007] The fixed support plate is connected to the threaded hole by dovetail nails, and the fixed support plate is prefabricated and connected to the lintel sleeve in advance.

[0008] The specific features of the utility model also include:

[0009] There is a safety gap between the fixed support plate and the beam plate.

[0010] At least one end of the top of the sleeve to be embedded under the plate is flush with the top plate of the bottom building.

[0011] By setting a fixed support plate, the fixed support plate can accurately control the pre-embedded height of the casing, greatly improving the pre-embedded accuracy;

[0012] By setting dovetail nails and aluminum film fixing, it replaces the traditional top plate welding, saving time and labor;

[0013] By setting a fixed support plate, multiple specifications and types can be provided to meet the needs of different embedded casing sizes.

[0014] When in use, first connect the two fixed support plates to the embedded sleeve according to the height difference of the structure, then seal the port of the embedded sleeve tightly, put the embedded sleeve into the beam groove during the binding process of the structural beam 4, and use dovetail nails to firmly connect the fixed support plate and the aluminum film of the embedded sleeve together. This is a preferred specific implementation manner of the utility model, but the embedded scope of the utility model is not limited to this, and it is suitable for beams of different sizes, embedded sleeves with different elevation requirements, etc.

[0015] The beneficial effects of the utility model are: simple design, easy operation, and the ability to make the pre-buried height of the casing more accurate. At the same time, dovetail nails are used to fix the casing during the pouring process without causing shaking, and the utility model can also be suitable for pre-buried casings of different specifications and sizes.

[0019] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0020] See also Figure 1 and 2 A welding-free installation lintel sleeve comprises a fixed support plate 2 of the sleeve, wherein both ends of the fixed support plate 2 are provided with threaded holes, and the threaded holes are used for fixing dovetail nails and aluminum films;

[0021] The fixed support plate 2 is connected to the threaded hole by dovetail nails, and the fixed support plate 2 is prefabricated and connected to the lintel sleeve in advance.

[0022] There is a safety gap between the fixed support plate 2 and the beam plate.

[0023] At least one end of the top of the casing embedded under the board must be flush with the top board of the bottom building.

[0024] By setting the fixed support plate 2, the fixed support plate 2 can accurately control the pre-embedded height of the casing, greatly improving the pre-embedded accuracy;

[0025] By setting dovetail nails and aluminum film fixing, it replaces the traditional top plate welding, saving time and labor;

[0026] By setting the fixed support plate 2 , multiple specifications and types can be provided to meet the needs of different sizes of embedded sleeves 3 .

[0027] When in use, first connect the two fixed support plates 2 to the embedded sleeve 3 according to the height difference of the structure, then seal the port of the embedded sleeve 3 tightly, put the embedded sleeve 3 into the beam groove during the binding process of the structural beam 4, and use dovetail nails to firmly connect the fixed support plate 2 and the aluminum film of the embedded sleeve 3 together. This is a preferred specific implementation manner of the utility model, but the embedded scope of the utility model is not limited to this, and it is suitable for beams of different sizes, embedded sleeves 3 with different elevation requirements, etc.
