Description

Technical Field

[0001] This invention belongs to the field of guardrail technology, and more specifically, relates to a pre-embedded component device and its construction method that are easy to install and integrate with adjacent guardrails. Background Technology

[0002] In construction projects, the edges of stair treads, exposed areas of floor slabs, and balcony curbs are high-risk areas for falls from heights, and safety railings must be installed throughout the entire process to ensure construction and usage safety. Temporary edge railings must be erected from structural construction to the completion of interior decoration to meet on-site safety requirements; permanent decorative railings must be installed before project handover, serving both protective and architectural aesthetic purposes. Both types of railings require reliable bases for fixation to the building's concrete structure, and their installation process closely overlaps with the laying of floor tiles, stone, aluminum panels, and other decorative surfaces in terms of timing and space, making it a crucial aspect requiring coordination between architectural decoration and safety protection projects.

[0003] To address the issue of the connection between railing installation and decorative construction, existing technologies have developed various solutions. Some solutions use pre-embedded sleeve bases to position and connect railing posts, while others use zigzag connecting pieces with expansion bolts and grouting material to quickly assemble the posts. Still others involve casting the pre-embedded parts entirely within the concrete structure and covering them with the decorative surface to ensure the integrity of the appearance. However, all of the above solutions have the following drawbacks: (1) There are no special installation tools for sleeve connections, making it difficult to guarantee the connection's firmness, and welding the posts to the steel plates can easily damage the appearance of the decorative surface; (2) The practice of reserving pre-embedded holes and sealing them with grout is only applicable to balcony curbs, and construction on floor slabs and stairs will damage the protective layer of the structural steel reinforcement; (3) The solution of covering the pre-embedded parts entirely requires the complete removal of temporary guardrails before the decorative surface is laid, resulting in a long period of safety protection gaps in the adjacent areas.

[0004] Therefore, there is an urgent need for a connector and usage method that facilitates decoration and can be combined with edge protection railings, effectively avoiding the safety hazards caused by removing the railings when laying floor tiles, thereby achieving a permanent and temporary combination of edge protection, safe and efficient decoration construction, and complete unity of decorative effect. Summary of the Invention

[0005] To address the shortcomings of existing guardrail construction techniques, which cannot simultaneously achieve the reuse of bases for temporary and permanent guardrails, the continuity of edge protection during the decoration phase, and the integrity of the decorative surface layer, as well as the cumbersome installation process, limited applicable scenarios, and serious material waste, this invention provides a pre-embedded component device and its construction method that are easy to integrate with temporary guardrails and facilitate decoration.

[0006] To achieve the above objectives, the present invention provides an embedded component device that is easy to install and integrate with adjacent guardrails, comprising: an anchor bar embedded in a concrete foundation layer, with an embedded steel plate fixed to its top and an embedded threaded sleeve fixed to the bottom center of the embedded steel plate; an adapter threadedly connected to the embedded threaded sleeve, the adapter comprising a lower threaded portion and an upper connecting portion; a socket fitting fitted onto the upper connecting portion, the socket fitting having countersunk grooves around its perimeter; and a displacement component for adjusting the horizontal position of the socket fitting, including a component embedded in the countersunk groove. The countersunk sliding plate inside the groove passes through the countersunk screws that connect to the upper connecting part, and a pre-tightening spring is fitted on the countersunk screws; the adapter is screwed into the pre-embedded screw sleeve for fixation, and the corresponding specification socket plug is installed. The position of the socket plug is finely adjusted to align with the post through the displacement component. After inserting it into the temporary guardrail post, it is locked with bolts; the temporary post is removed, and floor tiles or stone are laid; the socket plug is replaced with one suitable for the permanent railing. After fine-tuning the alignment, neutral structural adhesive is applied to the socket contact surface, and it is inserted into the permanent railing post and locked for fixation, completing the temporary-permanent conversion construction.

[0007] Furthermore, the upper connecting part of the adapter has an adjusting screw hole at the position corresponding to the countersunk groove, and the countersunk screw engages with the adjusting screw hole to achieve locking.

[0008] Furthermore, the countersunk sliding plate is an arc-shaped structure or a flat plate structure adapted to the inner wall of the socket plug, the countersunk hole of the countersunk sliding plate is a countersunk structure, and the screw head does not protrude from the outer wall of the socket plug after the countersunk screw is tightened.

[0009] Furthermore, there are two or more anchor bars, the top of which is fully welded to the bottom of the pre-embedded steel plate, and the anchor bar body is tied and anchored to the building structure reinforcement.

[0010] Furthermore, the displacement components are arranged in four groups, symmetrically distributed in pairs around the socket, to achieve bidirectional fine adjustment of the socket horizontally.

[0011] Furthermore, the socket is a variable diameter tubular structure, including a first socket section with a constant diameter at the bottom and a second socket section with a reduced diameter at the top, which are adapted to guardrail posts of different pipe diameters.

[0012] Furthermore, the side wall of the connector is provided with a connecting screw sleeve, and the connector is inserted into the guardrail post and locked and fixed by bolts and connecting screw sleeves.

[0013] Furthermore, two sets of auxiliary bearing plugs are symmetrically arranged on the upper surface of the pre-embedded steel plate. The two sets of auxiliary bearing plugs are located on both sides of the bearing plug and are lower in height than the bearing plug, and are used to support the end posts of two adjacent sections of guardrail.

[0014] Furthermore, a bonding layer is formed by injecting structural adhesive into the connector 13, thereby bonding the connector 13, adapter 16, and displacement assembly 17 together.

[0015] According to another aspect of the present invention, a construction method for an embedded part device that is easy to decorate and integrate with adjacent guardrails is also provided, comprising the following steps: S1 structural pre-embedded construction: tie and fix the anchor bars to the structural steel bars, level the pre-embedded steel plate, seal the pre-embedded screw opening to prevent cement slurry from entering, and pour concrete to complete the concealed installation of the pre-embedded parts. S2 Temporary Protection Erection: Screw the adapter into the pre-embedded screw sleeve for fixation, install the corresponding specification socket plug, finely adjust the position of the socket plug with the displacement component to align with the post, insert it into the temporary guardrail post and lock it with bolts. S3 Decorative Surface Paving: Remove temporary columns and lay floor tiles or stone; S4 Permanent Railing Installation: Replace the socket plug with one suitable for the permanent railing, fine-tune the alignment, apply neutral structural adhesive to the socket contact surface, insert the permanent railing post and lock it in place to complete the temporary-permanent conversion construction.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The embedded part device of the present invention solves the inherent contradiction between traditional edge protection and decoration construction: during the temporary protection stage, the railing posts can be quickly inserted to meet the safety production requirements of the construction site; during the decoration and paving stage, only the temporary posts need to be pulled out, and the embedded parts are completely hidden under the paving layer. There is no need to dismantle the overall protection system, which completely eliminates the safety gap in the edge area, while ensuring the integrity of the decorative surface layer. It achieves a seamless connection between temporary protection and permanent railings, and takes into account the unity of construction safety and decorative effect.

[0017] 2. The embedded part device of the present invention adopts a modular and universal design, which can be adapted to the edge protection needs of all scenarios in building engineering: it can be adapted to ordinary steel pipe guardrails to meet the needs of scattered edge protection such as stairs and balconies; it can also be adapted to long-distance tool-type assembly guardrails, so that a single embedded part can support the splicing of two sections of guardrails, greatly reducing the number of embedded points; at the same time, it can be compatible with temporary protective columns and permanent decorative columns of different pipe diameters, comprehensively covering various edge protection scenarios of residential, commercial and industrial buildings, without the need to design embedded parts separately for different scenarios.

[0018] 3. The pre-embedded component device of the present invention has strong construction tolerance and flexible adjustment capabilities: it can realize bidirectional fine adjustment of the horizontal connector to offset the positional deviation caused by the pre-embedded construction and avoid rework caused by pre-embedded misalignment; at the same time, through the conversion connection structure, it can be adapted to different specifications of railing posts, and can be adapted to different types of railings without re-embedding, which greatly reduces the accuracy requirements of pre-embedded construction and the difficulty of on-site adjustment, and effectively improves on-site installation efficiency and adaptability.

[0019] 4. The embedded part device of the present invention has both economic and environmental benefits: on the one hand, the double socket design can significantly reduce the number of embedded points and reduce the material and labor costs of embedded construction; on the other hand, the device as a whole can be recycled and reused. After the temporary protection is removed, the embedded parts can be directly used for permanent railing installation without additional drilling or rebar installation, thus avoiding damage to the building structure; at the same time, no additional splicing or sealing components are required, reducing on-site material waste and having the dual advantages of improved construction efficiency and green environmental protection.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1 like Figure 1-2 As shown, this invention provides a pre-embedded component device that is easy to install and integrate with temporary guardrails. The device includes an anchor bar 11, a pre-embedded steel plate 12, and a socket 13. The socket 13 is inserted into the bottom of the post 21 of the guardrail 2, and includes a first socket section 131 and a second socket section 132. In this embodiment, the pre-embedded component device 1 is embedded inside the concrete foundation layer 3, with only the upper part of the socket 13 exposed. It directly connects to the steel pipe post 21 of the guardrail 2 without welding or subsequent drilling, making installation and dismantling convenient. This device is a permanent and temporary integrated pre-embedded connector adapted to steel pipe edge guardrails, mainly used in building stair treads, open areas of floor slabs, balcony curbs, and other edge locations. It can be pre-embedded during the structural construction stage, seamlessly connecting the entire process of temporary guardrail erection, decorative surface paving, and permanent railing installation. This solves the installation problems of traditional solutions where brickwork requires the removal of guardrails, resulting in safety gaps and the destruction of decorative integrity by posts penetrating bricks.

[0024] The anchor bar 11 is made of hot-rolled steel bars commonly used in construction engineering. It has at least two bars, and the bar body is a smooth round or ribbed structure. The top of the anchor bar 11 is fixed to the bottom of the pre-embedded steel plate 12 by full welding. The welding strength meets the requirements of pull-out resistance and lateral displacement resistance. Before pouring concrete for the foundation layer 3, the anchor bar 11 is tied and spot-welded to the original reinforcing steel bars of the building structure and anchored into the foundation layer 3 as a whole with the concrete pouring. Its function is to evenly transfer the load of the upper railing to the concrete structure, prevent the pre-embedded parts from shaking or being pulled out by external forces, and ensure the structural safety of the edge protection.

[0025] The embedded steel plate 12 is a rectangular flat steel plate with anchor bars 11 fixed at its bottom and a socket head cap 13 fixed at the center of its top. During installation of the embedded steel plate 12, the opening of the socket head cap 13 must be sealed with tape to prevent cement slurry from entering and clogging the pipe cavity. After pouring and demolding, the embedded steel plate 12 is completely hidden inside the concrete foundation layer 3, with only the socket head cap 13 exposed. By providing the embedded steel plate 12, it serves as the mounting base for the socket head cap 13, while also distributing the concentrated load from above, thus preventing stress concentration damage at the root of the socket head cap.

[0026] The socket 13 is vertically fixed to the top of the embedded steel plate 12 and exposed on the foundation layer 3. It is inserted into the steel pipe post 21 of the guardrail 2 and includes a first socket section 131 and a second socket section 132. The first socket section 131 is the lower section of the socket 13, which is a straight pipe section of equal diameter. Its outer diameter precisely matches the bottom inner diameter of the steel pipe post 21. It can be directly inserted into the internal cavity of the steel pipe post 21 to form a clearance fit, completing the quick positioning and initial socket connection of the post without the need for on-site adjustment. The second socket section 132 is the upper section of the socket 13. It adopts a reducing head structure, with a pipe diameter smaller than that of the first socket section 131. It can be adapted to steel pipe guardrail posts and conversion connectors of different specifications, and is compatible with different post pipe diameters of temporary guardrails and permanent decorative railings, achieving universal use for both temporary and permanent purposes.

[0027] Furthermore, connecting screw sleeves 133 are respectively provided on the side walls of the first socket section 131 and the second socket section 132. After the column 21 is inserted into place, the bolt is threaded through the side wall of the column and connected to the connecting screw sleeve 133 to achieve rigid fixation between the column 21 and the socket 13, preventing the temporary guardrail from shaking or falling off due to collision or wind, and ensuring the safety and reliability of the edge protection.

[0028] In this embodiment, during the installation of the device, the anchor bar 11 is fixed to the structural steel reinforcement, the embedded steel plate 12 is leveled, the pipe opening of the socket 13 is sealed, and then concrete is poured to complete the pre-installation of the embedded device 1. During the temporary protection stage, the bottom of the post 21 of the steel pipe guardrail 2 is aligned with the socket 13 and inserted, and the bolt is tightened through the connection hole 133 to quickly erect temporary edge protection, meeting the construction safety requirements. During the decoration and paving stage, it is only necessary to unscrew the bolts and pull out the temporary post 2. 1. It can completely lay paving layers such as floor tiles and stone. 5. When laying floor tiles, a hole opener can be used to make holes in the floor tiles according to the outer diameter of the embedded part socket pipe. The processed floor tiles are then inserted into the socket pipe. After the floor tiles are laid, the entire protection system does not need to be removed and there is no safety gap period. During the permanent railing installation stage, neutral structural adhesive is applied to the surface of the socket plug 13 and the bottom of the permanent decorative railing post. The permanent decorative railing post is then inserted to complete the final fixation and achieve a seamless connection between permanent and temporary edge protection.

[0029] Example 2 like Figure 3-4 As shown, this embodiment provides a pre-embedded component device that is easy to decorate and integrate with adjacent guardrails. The device includes an anchor bar 11, a pre-embedded steel plate 12, a socket plug 13 and a secondary socket plug 14. The secondary socket plugs 14 are symmetrically arranged on both sides of the socket plug 13. The two sets of secondary socket plugs 14 serve as the end post socket bases for two adjacent sections of tool-type guardrails.

[0030] In this embodiment, the socket 13 is a centrally reserved component. It is a variable diameter pipe or equal diameter pipe structure, vertically fixed to the central position of the top of the embedded steel plate 12, and exposed on the foundation layer 3. During the temporary protection stage, it is left unconnected to the column and used as a reserved interface.

[0031] The bottoms of the two sets of auxiliary connectors 14 are fully welded to the upper surface of the embedded steel plate 12, and the pipe body does not contact the side wall of the connector 13, maintaining an independent insertion space. Furthermore, the auxiliary connector 14 is lower in height than the connector 13. When the connector 13 is inserted into the intermediate column 21, the flange, reinforcing rib, or transverse connecting rod at the bottom of the column will not collide or interfere with the top surface of the auxiliary connector 14, ensuring that the intermediate column can be fully inserted. Simultaneously, the left and right end columns can also be inserted independently without interference. Furthermore, the side wall of the auxiliary connector 14 is also provided with a connecting threaded sleeve 133. After the column 21 is inserted, a bolt is threaded through the side wall of the column and connected to the connecting threaded sleeve 133, achieving rigid fixation between the column 21 and the auxiliary connector 14.

[0032] By symmetrically arranging two sets of auxiliary connectors 14 on both sides of the connector 13, the right end post of the left tool-type guardrail 2 is inserted into the left auxiliary connector 14, and the left end post of the adjacent tool-type guardrail 2 on the right is inserted into the right auxiliary connector 14, leaving the middle connector 13 unused; through this design, a single embedded part can achieve the splicing and docking of two sections of tool-type guardrail, eliminating the need to set independent embedded parts at the splicing points of the two sections of guardrail. Long-distance edge protection can reduce the number of embedded points by 50%, significantly reducing the amount of embedded construction work; at the same time, the splicing nodes share a single embedded part, making the overall continuity of the guardrail stronger and preventing loosening and misalignment at the splicing points.

[0033] In this embodiment, during the installation of the device, the anchor bar 11 is fixed to the structural steel bar, the embedded steel plate 12 is leveled, and the pipe openings of the socket 13 and the auxiliary socket 14 are sealed respectively before pouring concrete to complete the pre-embedded installation of the embedded device 1. During the temporary protection stage, the right end post of the left tool-type guardrail 2 is inserted into the left auxiliary socket 14, and the left end post of the adjacent right tool-type guardrail 2 is inserted into the right auxiliary socket 14, leaving the middle socket 13 unattended. The bolts are screwed into the connecting sleeves 133 of the auxiliary socket 14 and locked, quickly completing the assembly of the long-distance continuous protection. No additional splicing components are required. During the decoration and paving stage, only the bolts need to be unscrewed and the end posts of the two sections of guardrail need to be pulled out to completely lay the paving layer 5, such as floor tiles and stone. The socket plug 13 and the auxiliary socket plug 14 are both hidden under the paving layer. The entire protection system does not need to be removed throughout the process, and there is no safety gap period. During the permanent railing installation stage, neutral structural adhesive is applied to the surface of the middle socket plug 13 (or auxiliary socket plug 14), the permanent decorative railing post is inserted, and the bolt is screwed into the connecting sleeve 133 to lock it, thus completing the final fixation and achieving a seamless permanent connection of edge protection.

[0034] Example 3 like Figure 5-7 As shown, this embodiment provides a pre-embedded component device that is easy to install and integrate with temporary guardrails. The device includes an anchor bar 11, a pre-embedded steel plate 12, a socket head cap 13, a pre-embedded threaded sleeve 15, an adapter 16, and a displacement component 17. The pre-embedded threaded sleeve 15 is fixedly installed at the center of the bottom of the pre-embedded steel plate 12, located within the foundation layer 3. The adapter 16 includes a lower threaded rod 161 and an upper connecting part 162. The lower threaded rod 161 is threadedly connected to the pre-embedded threaded sleeve 15, and the upper connecting part 162 is fitted inside the socket head cap 13. By providing the adapter 16, it can adapt to different types of socket head caps 13, avoiding incompatibility due to differences in specifications between temporary and permanent guardrail posts 21. The displacement component 17 is used to adjust the horizontal and vertical positions of the socket head cap 13, preventing errors during pre-embedding operations from causing the socket head cap 13 to malalign with the post 21. The embedded part device 1 in this embodiment is an adjustable, multi-specification adaptable permanent and temporary combined embedded connection part, which is suitable for scenarios with high installation accuracy requirements and large differences in specifications between temporary and permanent railing posts, such as balconies of fine-decorated residences, edges of commercial public areas, stair treads, etc. The embedded part device 1 is compatible with different specifications of sockets 13 and posts 21 through adapter 16, which solves the problem of mismatch between the pipe diameters of temporary and permanent railing posts. The displacement component 17 realizes the horizontal and vertical two-way fine adjustment of the socket 13, which offsets the positional error caused by the pre-embedded construction and ensures the precise alignment of the posts.

[0035] The anchor bar 11 is vertically fixed at the bottom of the embedded steel plate 12. The embedded steel plate 12 is a rectangular flat steel plate with a through hole in the center for the lower screw part 161 of the adapter 16 to pass through. An embedded screw sleeve 15 is vertically fixed at the center of its bottom. The top is connected to the socket plug 13 through the adapter 16, forming a layered structure of embedded base-adjustment conversion-socket column.

[0036] The socket 13 is an adjustable socket component with an overall tubular structure. It is sleeved on the outside of the upper connecting part 162 of the adapter 16. The side wall of the tube has a countersunk groove 134, which can be adapted to guardrail posts 21 of different specifications. The socket 13 of the corresponding specification can be replaced according to the tube diameter of the post of the temporary guardrail or permanent decorative railing. Universal connection can be achieved through the adapter 16 without the need for re-embedding.

[0037] The pre-embedded threaded sleeve 15 is an internally threaded sleeve, vertically welded and fixed to the center of the bottom of the pre-embedded steel plate 12, and completely embedded inside the concrete foundation layer 3. The threaded opening is aligned with the center through hole of the pre-embedded steel plate 12. The pre-embedded threaded sleeve 15 is threadedly connected to the lower threaded part 161 of the adapter 16, realizing the rigid fixation of the adapter 16 to the pre-embedded base, thereby providing reliable threaded connection strength for the adapter 16, realizing the detachable replacement of the adapter 16, and adapting to different adjustment needs.

[0038] The adapter 16 is a specification conversion and connection transition component, including a lower screw part 161 and an upper connecting part 162. The lower screw part 161 is an externally threaded rod that passes through the central through hole of the pre-embedded steel plate 12 and is threadedly tightened with the pre-embedded screw sleeve 15 to achieve rigid fixation between the adapter 16 and the pre-embedded base. The upper connecting part 162 is a columnar structure with an outer diameter smaller than the inner diameter of the socket plug 13. Its top is located below the connecting screw sleeve 133 and serves as a sliding adjustment base for the socket plug 13 by being fitted inside it. Furthermore, the side wall of the upper connecting part 162 is provided with four sets of adjusting screw holes 163 to provide a locking reference for displacement adjustment.

[0039] The displacement assembly 17 is used to achieve horizontal bidirectional fine adjustment of the socket 13, and there are 4 sets in total. Each set of displacement assembly 17 includes a countersunk slide plate 171, a countersunk screw 172, and a spring 173. The countersunk slide plate 171 is adapted to the countersunk groove 134. It is an arc-shaped slider or a flat slider with an isosceles trapezoidal vertical cross section that tapers from the outside to the inside and is embedded in the countersunk groove 134 of the socket 13. It can slide laterally along the countersunk groove 134. A countersunk hole 174 is opened in the center of the plate for the countersunk screw 172 to pass through. Furthermore, the diameter of the countersunk hole 174 is slightly larger than the body of the countersunk screw 172. When the socket 13 is a cylindrical structure, the countersunk screw 172 can be axially adjusted to align with the adjusting screw hole 163. After the countersunk screw 172 is tightened, the screw head does not protrude from the outer wall of the socket 13. The countersunk screw 172 passes through the countersunk hole 174 of the countersunk slide plate 171 and is screwed into the adjusting screw hole 163 of the upper connecting part 162 of the adapter 16 to achieve locking. The spring 173 is sleeved on the shank of the countersunk screw 172, with its two ends abutting against the inner wall of the socket 13 and the outer wall of the upper connecting part 162 of the adapter 16, respectively, to provide pre-tightening force.

[0040] When a positional error occurs during pre-embedding, loosen the four sets of countersunk screws 172. The socket 13 can then be adjusted horizontally and vertically along the countersunk groove 134 to align with the installation position of the column 21. After adjustment, tighten the countersunk screws 172. The preload of the spring 173 prevents the socket 13 from shifting due to external forces, achieving precise locking. By incorporating the displacement component 17, small-range pre-embedding positional errors can be offset, significantly reducing the precision requirements of pre-embedding construction, avoiding rework due to pre-embedding misalignment, and improving installation efficiency.

[0041] In this embodiment, during the pre-embedded construction of the device, the anchor bar 11 is fixed to the structural steel bar, the pre-embedded steel plate 12 is leveled, the threaded opening of the pre-embedded threaded sleeve 15 is sealed, and then concrete is poured to complete the pre-embedded installation of the pre-embedded component base. During the temporary protection stage construction, the lower screw part 161 of the adapter 16 is screwed into the pre-embedded threaded sleeve 15 for fixation. The socket plug 13, which is compatible with the specifications of the temporary protection column, is inserted, and the position of the socket plug 13 is finely adjusted by the displacement component 17 to align with the column 21. During the decoration and paving stage construction, the bolts are unscrewed, the temporary column 21 is pulled out, and the device is removed. The socket plug 13 is used for laying floor tiles and stone without any safety gaps. During the permanent railing installation phase, the socket plug 13 is replaced with one that matches the specifications of the permanent decorative post, and the alignment is finely adjusted using the displacement component 17. Structural adhesive is injected into the socket plug 13 to form a bonding layer, which binds the socket plug 13, adapter 16, and displacement component 17 together to prevent shaking. After completion, neutral structural adhesive is applied to the surface of the socket plug 13 and the bottom of the permanent decorative railing post, and then inserted into the permanent decorative railing post to complete the final fixation and achieve a seamless permanent-temporary connection for edge protection.

[0042] The embedded part device of this invention solves the inherent contradiction between traditional edge protection and decoration construction: the railing posts can be quickly inserted during the temporary protection stage to meet the safety production requirements of the construction site; during the decoration and paving stage, only the temporary posts need to be pulled out, which completely eliminates the safety gap in the edge area, while ensuring the integrity of the decorative surface layer, realizing the seamless connection between temporary protection and permanent railings, and taking into account the unity of construction safety and decorative effect.

[0043] The embedded part device of the present invention adopts a modular and universal design, which can be adapted to the edge protection needs of all scenarios in building engineering: it can be adapted to ordinary steel pipe guardrails to meet the needs of scattered edge protection such as stairs and balconies; it can also be adapted to long-distance tool-type assembled guardrails, so that a single embedded part can support the splicing of two sections of guardrails, greatly reducing the number of embedded points; at the same time, it can be compatible with temporary protective columns and permanent decorative columns of different pipe diameters, comprehensively covering various edge protection scenarios of residential, commercial and industrial buildings, without the need to design embedded parts separately for different scenarios.

[0044] The pre-embedded component device of the present invention has strong construction tolerance and flexible adjustment capabilities: it can realize bidirectional fine adjustment of the horizontal connector to offset the positional deviation caused by the pre-embedded construction and avoid rework caused by pre-embedded misalignment; at the same time, through the conversion connection structure, it can be adapted to different specifications of railing posts, and can be adapted to different types of railings without re-embedding, which greatly reduces the accuracy requirements of pre-embedded construction and the difficulty of on-site adjustment, and effectively improves on-site installation efficiency and adaptability.

[0045] The embedded part device of the present invention has both economic and environmental benefits: on the one hand, the double socket design can significantly reduce the number of embedded points and reduce the material and labor costs of embedded construction; on the other hand, the device as a whole can be recycled and reused. After the temporary protection is removed, the embedded parts can be directly used for permanent railing installation without additional drilling or rebar installation, thus avoiding damage to the building structure; at the same time, no additional splicing or sealing components are required, reducing on-site material waste and combining the dual advantages of improved construction efficiency and green environmental protection.

[0046] The present invention also provides a construction method for a pre-embedded component device that is easy to install and integrate with adjacent guardrails, comprising the following steps: S1 structural pre-embedded construction: tie and fix the anchor bars to the structural steel bars, level the pre-embedded steel plate, seal the pre-embedded screw opening to prevent cement slurry from entering, and pour concrete to complete the concealed installation of the pre-embedded parts. S2 Temporary Protection Erection: Screw the adapter into the pre-embedded screw sleeve for fixation, install the corresponding specification socket plug, finely adjust the position of the socket plug with the displacement component to align with the post, insert it into the temporary guardrail post and lock it with bolts. S3 Decorative Surface Paving: Remove temporary columns and lay floor tiles or stone; S4 Permanent Railing Installation: Replace the socket plug with one suitable for the permanent railing, fine-tune the alignment, apply neutral structural adhesive to the socket contact surface, insert the permanent railing post and lock it in place to complete the temporary-permanent conversion construction.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
