Description

Technical Field

[0001] The utility model relates to the technical field of embedded structures in building construction, and specifically relates to an embedded structure for building construction. Background Technique

[0002] Building construction refers to the process of transforming building design drawings into physical buildings, covering multiple important steps and processes. During the construction process, construction embedded parts play a key role. These embedded parts are usually pre-installed at various positions in the structure according to the design requirements before concrete pouring. Their main functions include fixing, connecting, and supporting other components in the structure, such as walls, floors, and roofs. The precise installation of the embedded parts ensures the stability and durability of the building structure and also simplifies the subsequent construction process.

[0003] Chinese Patent Publication No. CN219491318U discloses a civil engineering construction embedded part, which relates to the field of building construction, including an installation plate and four embedded columns. Four through holes are provided on the installation plate along its diameter direction for the embedded columns to pass through. The embedded columns are horizontally slidably connected to the through holes, and a locking mechanism for fixing the embedded columns is arranged in the through holes. The utility model has the following advantages and effects: By setting the position-adjustable embedded columns, the distance between the four embedded columns can be adjusted, so as to adapt to external components of different specifications and improve the practicability of the embedded parts.

[0004] However, when this utility model is actually used, the following problems exist:

[0005] 1. When adjusting the position of the ordinary embedded columns, they need to be adjusted one by one in sequence, resulting in cumbersome and time-consuming adjustment steps, and even delaying the construction process;

[0006] 2. The fixed effect of the adjusted embedded columns is poor. During the pouring of cement, it is very easy for the embedded columns to be pushed and displaced again due to the impact force of the cement or the volume expansion of the solidified cement. Moreover, the structure of the ordinary embedded parts is single, resulting in a weakened stabilizing effect on the building. Content of the Utility Model

[0007] (1) Technical Problems to be Solved

[0008] In order to overcome the above-mentioned defects of the prior art, the utility model provides an embedded structure for building construction, which solves the problems in the prior art:

[0010] 2. The fixed effect of the pre-embedded column after adjustment is poor. During the pouring of cement, it is very easy for the pre-embedded column to be pushed and displaced again due to the impact force of the cement or the volume expansion during the solidification of the cement. Moreover, the structure of ordinary embedded parts is single, resulting in a weakened stabilizing effect on the building.

[0011] (II) Technical Solution

[0012] To achieve the above purposes, the present utility model is realized through the following technical solutions: A building construction pre-embedded structure includes a chassis fixed to the bottom of a cover.

Multiple groups of the first pre-embedded steel bars and the second pre-embedded steel bars are evenly and staggeredly distributed around the cover in a circular shaft array manner. Both the first pre-embedded steel bar and the second pre-embedded steel bar are set in a J shape.

[0014] Optionally, multiple groups of the feeding holes are opened. Multiple groups of the feeding holes are evenly distributed on the top end of the cover in a circular shaft array manner. The feeding holes communicate with the inside of the cover and the limiting groove.

[0015] Optionally, the top end of the handle is slidably inserted through the middle of the top end of the cover.

[0016] Optionally, two groups of the anti-loosening bolts are provided. Two groups of the anti-loosening bolts are symmetrically distributed on the top end of the cover. Multiple groups of the threaded holes are opened. Multiple groups of the threaded holes are evenly distributed on the upper surface of the turntable in a circular shaft array manner. The threaded holes are adapted to the anti-loosening bolts. The bottom end of the anti-loosening bolt passes through the cover and is threadedly inserted into the inside of the threaded hole.

[0017] Optionally, a square groove is opened at the bottom end of the cover, and four groups of the square grooves are opened. Four groups of the moving plates are provided. Four groups of the moving plates are evenly distributed on the upper surface of the chassis in a circular shaft array manner. The upper end of the moving plate is adapted to the square groove.

[0018] Optionally, a trapezoidal groove is formed in the top surface of the chassis, and the bottom end of the moving plate is provided as a trapezoidal block, and the trapezoidal block is adapted to the trapezoidal groove.

[0020] Optionally, four groups of limiting slide bars are provided. The limiting slide bars slide inside the limiting grooves, and the two are closely attached to each other without gaps.

[0021] (III) Beneficial effects

[0022] The utility model provides a pre-buried structure for building construction, which has the following beneficial effects:

[0023] 1. For this pre-buried structure for building construction, through the cooperative setting of the handle, chassis, turntable, moving plate, and limiting slide bar, when it is necessary to adjust the positions of multiple groups of second pre-buried steel bars, only need to rotate the handle counterclockwise, so that the limiting slide bar slides along the inside of the limiting groove, and under the limitation of the arc track of the limiting groove, the limiting slide bar drives the moving plate to move away from the cover at the same time. Thus, multiple groups of second pre-buried steel bars can move simultaneously in an expandable manner, making the position adjustment of the second pre-buried steel bars more convenient and rapid. It is not necessary for workers to adjust each group of second pre-buried steel bars one by one, and the operation steps are more simplified. To a certain extent, the construction process can be shortened, and greater convenience is also provided for workers.

[0024] 2. For this pre-buried structure for building construction, through the cooperative setting of the cover, first pre-buried steel bar, chassis, second pre-buried steel bar, anti-loosening bolt, and the formed feeding hole, threaded hole, and limiting groove, compared with ordinary pre-buried parts, the staggered distribution of the first pre-buried steel bar and the second pre-buried steel bar makes the device enhance the stability and tensile resistance of the building. After the turntable is fixed by the anti-loosening bolt, the turntable is not easy to rotate, effectively avoiding the random rotation of the turntable due to the impact force of the cement during cement pouring, resulting in the change of the original position of the second pre-buried steel bar, thereby affecting the pre-buried effect of the device. Then, by pouring the cement into the cover and the limiting groove from the feeding hole, the device is more integrated after the cement solidifies, and the fitting with the cement is closer, and it is not easy to cause accidents such as the depression of the device in the later stage due to the internal void of the device.

[0039] Embodiment 1;

[0040] Please refer toFigure 4 , the rotating assembly 13 includes a connecting column 131, a rotating disk 132 and a clamping groove 133.

Through the arrangement of the connecting column 131, the rotating disk 132 and the clamping groove 133, the turntable 8 and the chassis 5 are not easily separated directly, and the turntable 8 can rotate smoothly;

[0041] Embodiment Two;

[0042] Please refer to Figure 5 , the rotating assembly 13 includes a connecting column 131, a rotating disk 132 and a through groove 134. The through groove 134 is opened through the middle of the chassis 5.

[0043] Embodiment Three;

[0044] Please refer to Figure 6 , the rotating assembly 13 includes a connecting column 131, a rotating disk 132, a through groove 134 and a ball 135. The through groove 134 is opened through the middle of the chassis 5.

[0045] In the present utility model, the working steps of the device are as follows:

[0046] First, place the device at the designated position, and then adjust the positions of multiple groups of second embedded steel bars 6 according to the size requirements of the actual scenario. You can directly rotate the handle 4 counterclockwise. The handle 4 drives the turntable 8 to rotate counterclockwise, and the limit groove 11 rotates with the turntable 8. When the limit groove 11 rotates, since the moving plate 9 is restricted by the side grooves of the chassis 5 and the cover 1, it can only slide parallel to the side groove and the trapezoidal groove on the upper surface of the chassis 5. The limit slide rod 12 and the moving plate 9 are in a fixed state, and multiple groups of limit slide rods 12 will slide inside multiple groups of limit grooves 11 and move away from the handle 4 along the trajectory of the limit groove 11, causing multiple groups of moving plates 9 to move in an expanding manner simultaneously. The moving plate 9 drives the second embedded steel bars 6 to move synchronously. Wait until multiple groups of second embedded steel bars 6 are moved to the appropriate positions. Then, rotate the anti-loosening bolt 7 through the cover 1 and insert it into the threaded hole 10 at the corresponding position, so that the turntable 8 and the cover 1 are fixed, and the turntable 8 will no longer rotate randomly. Finally, when pouring cement, not only should the edges of the device be completely sealed with cement, but also part of the cement should be poured into the cover 1 from the feed hole 3. The cement will fill the gaps inside the cover 1 along the feed hole 3, thereby enhancing the stability and compressive resistance of the device.

[0047] Finally, the following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense.
