Description
Technical Field
[0001] The utility model relates to the technical field of embedded parts for stairs, in particular to an embedded part structure for a cantilevered steel structure staircase. Background Art
[0002] Embedded parts (prefabricated embedded parts) are components that are pre-installed (buried) in concealed projects. They are components placed during structure casting and are used for splicing when building the superstructure to facilitate the installation and fixation of the foundation of external engineering equipment. Embedded parts are mostly made of metal, such as steel bars or cast iron, and non-metallic rigid materials such as wood and plastic can also be used.
[0003] Embedded parts of stairs are used to enhance tensile strength. Stairs are components used for vertical transportation between floors in buildings. They are used for transportation between floors and when there is a large height difference. Stairs must also be installed in multi-story and high-rise buildings that have elevators and escalators as the main means of vertical transportation. Although high-rise buildings use elevators as the main means of vertical transportation, stairs must still be retained for escape in case of fire. Stairs are composed of continuous steps, platforms and enclosing components.
[0004] When the embedded parts of the stairs are used, since the rigid components on the embedded parts are fixed, the embedded parts and the stairs can only be spliced when the stairs and the embedded parts are completely on the same horizontal line. The position of the rigid components cannot be adjusted, which results in the need to adjust the overall position of the embedded parts when there is a certain deviation between the stairs and the embedded parts, which makes it inconvenient to splice the embedded parts with the stairs, affecting the efficiency of splicing the stairs and the embedded parts.
[0005] Therefore, the utility model provides an embedded component structure of a cantilevered steel structure staircase to solve the above problems. Utility Model Content
[0006] The utility model provides an embedded part structure for a cantilever steel structure staircase, aiming to solve the problem proposed in the background technology that the embedded part structure of the existing cantilever steel structure staircase cannot adjust the position of the rigid components, resulting in the need to adjust the overall position of the embedded parts when there is a certain deviation between the stairs and the embedded parts, which makes it inconvenient to splice the embedded parts with the stairs.
[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an embedded component structure for a cantilevered steel structure staircase, the embedded component structure comprising an embedded component body, sliding grooves arranged in a rectangular array on the upper surface of the embedded component body, sliding blocks slidably connected to the interior of the sliding grooves, a mounting mechanism mounted on the upper surface of the embedded component body, a plug-in mechanism mounted on the surface of the mounting mechanism, and an adjustment mechanism mounted inside the mounting mechanism;
[0008] The adjustment mechanism includes two main plates installed inside the installation mechanism, a sub-plate slidably arranged inside the two main plates, connecting grooves arranged in a rectangular array on the surface of the sub-plate, and a rotating rod arranged in the middle of the upper surface of the sub-plate;
[0009] The adjustment mechanism also includes a rotating disk installed on one end of the rotating rod, a knob arranged at the other end of the rotating rod, a linkage rod arranged on both sides of the lower surface of the rotating disk through a pin shaft, and four support blocks symmetrically arranged on the upper surfaces of the two main boards.
[0010] Furthermore, in the embedded part structure of the above-mentioned cantilever steel structure staircase, the installation mechanism includes two support plates respectively arranged on the surface of the sliding block, limiting grooves opened in a rectangular array on the outside of the support plates, limiting plates slidably arranged in the corresponding limiting grooves and arranged on the upper surface of the embedded part body, and guide grooves opened in a rectangular array on the inside of the support plates.
[0011] Furthermore, in the embedded part structure of the above-mentioned cantilever steel structure staircase, the installation mechanism also includes a guide rod arranged inside the sliding groove, a clamping spring arranged on the surface of the guide rod and arranged on the sliding block and the inner wall of the sliding groove, and a support block slidably arranged inside the guide groove and arranged in the middle of the upper surface of the embedded part body.
[0012] Furthermore, in the embedded parts structure of the above-mentioned cantilever steel structure staircase, the plug-in mechanism includes four adjustment boxes respectively arranged on both sides of the upper surface of the two support plates, a threaded rod arranged inside the adjustment box through a bearing seat, a plug-in block threaded on the surface of the threaded rod, a limiting mechanism installed inside the plug-in block, and a turntable arranged at one end of the threaded rod.
[0013] Furthermore, in the embedded parts structure of the above-mentioned cantilever steel structure staircase, the limiting mechanism includes a push plate arranged inside the plug-in block, a push rod arranged at the four corners of the lower surface of the push plate through a pin shaft and arranged inside the plug-in block, two flip plates respectively attached to one side of the two corresponding push rods, and an arc-shaped limit block arranged on one side of the flip plate.
[0014] Furthermore, in the embedded parts structure of the above-mentioned cantilever steel structure staircase, a stabilizing ring that fits with the sub-plate is provided on the surface of the rotating rod, and elastic rods are provided on both sides of the lower surface of the pushing plate. The elastic rods are arranged inside the plug-in block, and the surface of the plug-in block is provided with a plug-in groove corresponding to the existing staircase.
[0015] Beneficial effects:
[0016] By setting up the structures such as the embedded part body, the installation mechanism and the adjustment mechanism, the rotating rod is rotated according to the position of the cantilever steel structure staircase, so that the rotating disk drives the linkage rod to rotate, so that the linkage rod pulls the two support plates closer to or away from each other, thereby adjusting the distance between the two support plates, and adjusting the distance between the plug-in mechanism and the installation mechanism. In addition, the position of the plug-in block is fine-tuned by the mutual cooperation between the threaded rod and the plug-in block, making it more convenient to splice the cantilever steel structure staircase with the plug-in mechanism, facilitating the splicing of the cantilever steel structure staircase with the embedded part body, and making the embedded part body more convenient to use.
[0017] By setting structures such as the plug-in mechanism and the limiting mechanism, when adjusting the spacing between the support plates, the limiting plate and the supporting block cooperate with each other to support the two support plates, making the support plates more stable when moving, and applying a tightening force to the support plates through the elastic force of the tightening spring, thereby making the rotating rod more stable when adjusting the spacing between the support plates, making the spacing adjustment of the support plates more accurate;
[0018] After the cantilevered steel structure staircase is spliced with the embedded part body, concrete is poured on the embedded part body so that the concrete wraps the entire embedded part, thereby fixing the arc-shaped limit block, the push plate and other components through the concrete, making the cantilevered steel structure staircase more stable inside the plug-in block, and through the provision of components such as the support plate, the contact area between the embedded part body and the concrete is increased, thereby improving the overall stability of the device.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The utility model provides a pre-embedded component structure of a cantilevered steel structure staircase, such as Figure 1-Figure 5 As shown, an embedded component structure for a cantilevered steel structure staircase includes an embedded component body 1, sliding grooves 7 arranged in a rectangular array on the upper surface of the embedded component body 1, sliding blocks 8 slidably connected to the interior of the sliding grooves 7, a mounting mechanism mounted on the upper surface of the embedded component body 1, the sliding grooves 7 and the sliding blocks 8 cooperating with each other to make the mounting mechanism more stable when the position is adjusted by the adjustment mechanism, a plug-in mechanism mounted on the surface of the mounting mechanism, and an adjustment mechanism mounted inside the mounting mechanism;
[0028] The adjustment mechanism includes two main boards 2 installed inside the installation mechanism, a sub-board 3 that is slidably arranged inside the two main boards 2, a connecting groove 4 opened in a rectangular array on the surface of the sub-board 3, and a rotating rod 5 arranged in the middle of the upper surface of the sub-board 3. Through the mutual cooperation between the main board 2 and the sub-board 3, when the support plate 9 is adjusted in position, the main board 2 will not cause movement obstruction to the support plate 9, and can also guide the movement of the support plate 9, so that the support plate 9 is more stable when moving.
[0029] The adjustment mechanism also includes a rotating disk 6 installed at one end of the rotating rod 5, a knob set at the other end of the rotating rod 5, a linkage rod 24 set on both sides of the lower surface of the rotating disk 6 through a pin shaft, and four fixed blocks symmetrically set on the upper surfaces of the two main boards 2.
[0030] By rotating the rotating rod 5, the rotating disk 6 rotates accordingly, so that the linkage rod 24 moves synchronously, pulling the support plate 9 to move, adjusting the distance between the two support plates 9, and thus the position of the plug-in mechanism on the support plate 9 is adjusted synchronously, so that the plug-in mechanism and the cantilevered steel structure stairs can be spliced more accurately.
[0031] Exemplarily, the mounting mechanism includes two support plates 9 respectively arranged on the surface of the sliding block 8, limit grooves 10 opened in a rectangular array on the outside of the support plate 9, limit plates 11 slidably arranged inside the corresponding limit grooves 10 and arranged on the upper surface of the embedded part body 1, and guide grooves 12 opened in a rectangular array on the inside of the support plate 9.
[0032] By inserting the limiting plate 11 into the limiting groove 10, the support plate 9 is limited, so that the support plate 9 is more stable when in use. When the spacing of the support plates 9 is adjusted, the limiting groove 10 to which the limiting plate 11 is inserted is replaced, so that the limiting plate 11 can continue to support and limit the support plate 9, so that the support plate 9 is more stable after adjustment.
[0033] During the adjustment of the support plate 9, the support block 13 slides inside the guide groove 12, so that the support block 13 and the guide rod 14 synchronously limit the support plate 9, and through the mutual cooperation of the support block 13 and the guide rod 14, the contact area between the embedded part body 1 and the concrete is increased, thereby making the embedded part body 1 more stable during installation.
[0034] The mounting mechanism also includes a guide rod 14 arranged inside the sliding groove 7, a tightening spring 15 arranged on the surface of the guide rod 14 and arranged on the sliding block 8 and the inner wall of the sliding groove 7, and a support block 13 slidably arranged inside the guide groove 12 and arranged in the middle of the upper surface of the embedded part body 1.
[0035] Through the mutual cooperation between the guide rod 14 and the clamping spring 15, a clamping force is applied to the support plate 9, so that when the rotating rod 5 drives the support plate 9 to adjust the spacing, the support plate 9 is supported by the clamping force, making the support plate 9 more stable during the adjustment process and making the spacing adjustment of the support plate 9 more accurate.
[0036] Exemplarily, the plug-in mechanism includes four adjustment boxes 16 respectively arranged on both sides of the upper surface of the two support plates 9, a threaded rod 17 arranged inside the adjustment box 16 through a bearing seat, a plug-in block 18 threadedly arranged on the surface of the threaded rod 17, a limiting mechanism installed inside the plug-in block 18, and a turntable arranged at one end of the threaded rod 17.
[0037] By rotating the threaded rod 17, the plug-in block 18 slides on the surface of the adjustment box 16, and the position of the plug-in block 18 is adjusted so that the plug-in block 18 is more adapted to the joint of the cantilevered steel structure staircase, thereby making the cantilevered steel structure staircase more accurate when spliced with the embedded part body 1, so that the embedded part body 1 can be suitable for splicing cantilevered steel structure stairs at different positions.
[0038] The limiting mechanism includes a push plate 19 arranged inside the plug-in block 18, a push rod 20 arranged at the four corners of the lower surface of the push plate 19 through a pin shaft and arranged inside the plug-in block 18, two flip plates 21 respectively attached to one side of the two corresponding push rods 20, and an arc-shaped limit block 22 arranged on one side of the flip plate 21.
[0039] When the joint of the cantilever steel structure staircase is inserted into the interior of the plug-in block 18, the extrusion push plate 19 slides inside the plug-in block 18, so that the push rod 20 pushes the flip plate 21 to rotate inside the plug-in block 18, so that the flip plate 21 drives the arc-shaped limit block 22 to fit the joint of the cantilever steel structure staircase, limiting the joint of the cantilever steel structure staircase, so that when the concrete is poured subsequently, the concrete enters the interior of the plug-in block 18, and the mutual cooperation between the concrete and the arc-shaped limit block 22 makes the splicing of the cantilever steel structure staircase and the plug-in block 18 more stable.
[0040] The surface of the rotating rod 5 is provided with a stabilizing ring that fits with the sub-plate 3, and elastic rods 23 are provided on both sides of the lower surface of the push plate 19. The elastic rods 23 are arranged inside the plug-in block 18, and the surface of the plug-in block 18 is provided with a plug-in groove corresponding to the existing staircase. Through the setting of the elastic rod 23, the cantilevered steel structure staircase is prevented from falling directly into the interior of the plug-in block 18 and affecting the plug-in block 18. In addition, through the setting of the elastic rod 23 on the stabilizing ring, the contact area between the concrete and the embedded part body 1 is increased, thereby improving the overall stability of the device.
[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
