Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a wall pre-embedded component installation and positioning structure. Background Technology

[0002] Underground utility tunnels are comprehensive buildings that integrate multiple disciplines such as electrical, HVAC, and water supply and drainage. Due to limited underground space, in order to improve space utilization, pre-embedded parts are fixed to the walls to facilitate the later installation of pipes and cables.

[0003] Currently, the main method for installing embedded parts in underground utility tunnels is by welding them to the reinforcing steel bars. However, this method cannot be completed independently by a welder and requires multiple people to work together. Furthermore, the welding process, which involves welding the embedded parts to the wall reinforcement, can damage the main reinforcement bars, affecting the structural durability and safety. After welding, any deviations in the spacing of the embedded parts are difficult to correct. Since the embedded parts and the wall reinforcement form a unified whole, if the reinforcement bars tilt and need correction, the position of the embedded parts will shift along with the steel bars. Repairing the embedded parts after the concrete is poured is not only time-consuming and labor-intensive but also compromises the integrity of the embedded parts.

[0004] Chinese patent application document with application number 201611203730.7 discloses a building embedded part installation and fixing structure, including embedded parts, templates and template fixing frames. The rivet steel bars of the embedded parts are set in the concrete steel reinforcement skeleton. The plate of the embedded parts is provided with at least two tie bolt through holes. The template is placed on the outside of the plate of the embedded parts. The back rib square timber is placed on the outside of the template. The vertical steel pipe is placed on the outside of the channel steel. The tie bolts are sequentially passed through the bolt through holes on the plate of the embedded parts, the tie bolt through holes on the template and the gap between the two vertical steel pipes. A washer and a nut are set on the tie bolts on the outside of the template. A slotted plate is set on the tie bolts on the outside of the vertical steel pipe. Two nuts are set on the tie bolts on the outside of the plate. The following shortcomings exist in the installation and fixing structure of the building's embedded parts: After the template is accurately positioned, the embedded parts are then fixed to the template one by one by tie bolts. On the one hand, due to the limitation of the template, it is difficult to adjust the height and relative position of each embedded part, which affects the positioning accuracy; on the other hand, the relative position of each embedded part is repositioned during the fixing process and the height of each embedded part is adjusted one by one during the fixing process, which is cumbersome and inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a wall pre-embedded part installation and positioning structure with high positioning accuracy, easy operation and high construction efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A wall pre-embedded component installation and positioning structure includes a wall steel frame and two templates located on both sides of the wall steel frame. The wall pre-embedded component installation and positioning structure also includes a vertically arranged positioning rod and multiple pre-embedded components. The positioning rod is adjustablely embedded in any template to divide the template into two sub-molds. Each of the pre-embedded components is fixed inside the positioning rod and arranged at intervals along the vertical direction.

[0007] As a further improvement to the above technical solution: The molded body and the positioning rod are respectively provided with vertical grooves and vertical inserts on opposite sides, and the vertical inserts are vertically inserted into the vertical grooves.

[0008] The inner surface of the positioning rod is flush with the inner surface of the mold body.

[0009] The embedded part is fixed to the positioning rod by fixing bolts.

[0010] The embedded component includes an embedded plate and an anchor rod. The embedded plate is attached to the inner side of the positioning rod and has a vertical groove. The fixing bolt passes through the vertical groove, and the anchor rod is fixed on the side of the embedded plate facing away from the positioning rod.

[0011] The two templates are connected by a docking mechanism.

[0012] The docking mechanism includes a docking screw, with clamping nuts at both ends of the docking screw. A crossbar is provided on the outer side of each of the two templates. The docking screw passes through the two templates, and the clamping nuts at both ends of the docking screw are respectively clamped onto the crossbars on the outer side of the two templates.

[0013] The wall embedded part installation and positioning structure also includes a lifting and adjusting mechanism for lifting and adjusting the positioning rod.

[0014] The lifting and adjusting mechanism includes a base and a telescopic adjusting component. An external protrusion is fixed on the outer side of the bottom of the positioning rod. The base is located on the ground. The bottom end of the telescopic adjusting component is connected to the base, and the top end is connected to the external protrusion. The inner side of the base is close to the outer side of the embedded part and the two molded bodies.

[0015] The telescopic adjustment assembly includes a lower screw, an upper screw, and a threaded sleeve with opposite internal thread directions at both ends. The bottom end of the lower screw is connected to the base, and the top end is threaded to the bottom end of the threaded sleeve. The bottom end of the upper screw is threaded to the top end of the threaded sleeve, and the top end is connected to the outer protrusion.

[0016] Compared with the prior art, the advantages of this utility model are: The construction process of this utility model's wall embedded part installation and positioning structure is as follows: First, the embedded parts are fixed to the inside of the positioning rod according to the actual vertical spacing requirements. After two templates are fixed to both sides of the wall steel frame (one template includes two sub-molds, with a gap reserved between the two sub-molds for the vertical insertion of the positioning rod), the positioning rod is vertically inserted between the two sub-molds. The positioning rod is then adjusted to the required height and fixed. Alternatively, one sub-mold, the positioning rod, and another sub-mold can be horizontally positioned and fixed sequentially, splicing them into a single piece. Since each embedded part is first positioned and fixed at a relative distance on the positioning rod, and then the whole assembly is positioned between the two sub-molds using the positioning rod, on the one hand, the overall height can be adjusted by raising and lowering the positioning rod, eliminating the need to adjust the relative positions of each embedded part, resulting in high positioning accuracy. On the other hand, each embedded part can be pre-positioned and fixed on the positioning rod (e.g., pre-fixed on a horizontally placed positioning rod at the factory), and the overall height can be adjusted on-site, making the operation easy and the construction efficiency high.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example 1: Figures 1 to 6This invention illustrates an embodiment of the wall embedded part installation and positioning structure. The wall embedded part installation and positioning structure of this embodiment includes a wall steel frame 1 and two templates 2 located on both sides of the wall steel frame 1. The wall embedded part installation and positioning structure also includes a vertically arranged positioning rod 3 and multiple embedded parts 4. The positioning rod 3 is adjustablely embedded in any template 2, dividing the template 2 into two mold bodies 21. Each embedded part 4 is fixed on the inner side of the positioning rod 3 (towards the wall steel frame 1) and arranged vertically at intervals.

[0033] The construction process of this wall embedded part installation and positioning structure is as follows: First, fix the embedded part 4 to the inside of the positioning rod 3 according to the actual vertical spacing requirements. After the two templates 2 are fixed to both sides of the wall steel frame 1 (one template 2 includes two sub-molds 21, with a gap reserved between the two sub-molds 21 for the vertical insertion of the positioning rod 3), vertically insert the positioning rod 3 between the two sub-molds 21. After adjusting the positioning rod 3 to the required height, fix it. Of course, one sub-mold 21, the positioning rod 3, and the other sub-mold 21 can also be horizontally positioned and fixed sequentially, splicing them into a whole piece. Since each embedded part 4 is first positioned and fixed on the positioning rod 3 with a relative spacing, and then the whole is positioned between the two molded bodies 21 by the positioning rod 3, on the one hand, the overall height can be adjusted by raising and lowering the positioning rod 3, without the need to adjust the relative position of each embedded part 4, resulting in high positioning accuracy. On the other hand, each embedded part 4 can be pre-positioned and fixed on the positioning rod 3 (such as pre-fixed on a horizontally placed positioning rod 3 in the factory), and the overall height can be adjusted on site, making the operation easy and the construction efficiency high.

[0034] Furthermore, such as Figure 3 As shown, in this embodiment, the mold-parting body 21 and the positioning rod 3 are respectively provided with vertical grooves 211 and vertical inserts 31 on opposite sides, and the vertical inserts 31 are vertically inserted into the vertical grooves 211. In this way, the mold-parting bodies 21 on the left and right sides can be positioned and fixed first, and then the positioning rod 3 is inserted from top to bottom between the left and right mold-parting bodies 21, so that the vertical inserts 31 on the opposite sides of the mold-parting body 21 and the positioning rod 3 are vertically inserted into the vertical grooves 211.

[0035] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the inner surface of the positioning rod 3 is flush with the inner surface of the mold body 21. Thus, after the concrete structure is formed by pouring concrete in the space where the wall steel frame 1 is located, the embedded part 4 can be flush with the outer surface of the concrete structure, thus protruding to the outside.

[0036] Furthermore, such as Figure 5 As shown, in this embodiment, the embedded part 4 is fixed to the positioning rod 3 by the fixing bolt 8, which makes disassembly and adjustment convenient.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the embedded part 4 includes an embedded plate 41 and an anchor rod 42. The embedded plate 41 is attached to the inner side of the positioning rod 3 and has a vertical groove 411. The fixing bolt 8 passes through the vertical groove 411, and the anchor rod 42 is fixed to the side of the embedded plate 41 facing away from the positioning rod 3. The fixing bolt 8 passes through the vertical groove 411. Loosening the fixing bolt 8 can adjust the relative spacing of the fixing bolt 8. After adjustment, the fixing bolt 8 can be loosened again. Of course, in other embodiments, the fixing bolt 8 can be replaced by a screw, and the vertical groove 411 can be replaced by multiple vertically spaced threaded holes. The fixing bolt 8 is threadedly connected to the threaded holes. Preferably, an embedded part 4 is fixed by at least two fixing bolts 8, which helps to prevent rotational displacement and improve stability.

[0038] Furthermore, in this embodiment, the two templates 2 are connected by a docking mechanism 5 to improve overall strength. Of course, the outer side of the template 2 can be fixed to the ground by a fixing frame.

[0039] Further, in this embodiment, the docking mechanism 5 includes a docking screw 51, with clamping nuts 52 at both ends of the docking screw 51. Crossbars 53 are provided on the outer sides of the two templates 2. The docking screw 51 passes through the two templates 2, and the clamping nuts 52 at both ends of the docking screw 51 are respectively clamped onto the crossbars 53 on the outer sides of the two templates 2. Preferably, as shown... Figure 1 As shown, the crossbars 53 are arranged in pairs, one above the other, with the ends of the crossbars 53 passing between the two pairs of crossbars 53. The clamping nuts 52 are pressed onto the two pairs of crossbars 53 by pressure pads.

[0040] Furthermore, multiple fixing rods 9 are provided on the outer side of the positioning rod 3. The fixing rods 9 are fixed to the crossbar 53 by fixing nuts 91, thereby improving the stability of the positioning rod 3. Specifically, the fixing rods 9 pass between a corresponding pair of crossbars 53, and the fixing rods 9 are provided with fixing nuts 91. The fixing nuts 91 are pressed tightly onto the pair of crossbars 53 by pressure pads.

[0041] Example 2: Figures 7 to 10 This illustration shows an embodiment of the wall embedded part installation and positioning structure of this utility model. The wall embedded part installation and positioning structure of this embodiment also includes a lifting and adjusting mechanism 6 for raising and lowering the positioning rod 3. The height of the positioning rod 3 can be adjusted using the lifting and adjusting mechanism 6, thereby adjusting the height of each embedded part 4, which is convenient.

[0042] Furthermore, such as Figure 7 and Figure 10As shown, in this embodiment, the lifting adjustment mechanism 6 includes a base 61 and a telescopic adjustment assembly 62. An external protrusion 7 is fixed to the outer bottom of the positioning rod 3. The base 61 is placed on the ground. The bottom end of the telescopic adjustment assembly 62 is connected to the base 61, and the top end is connected to the external protrusion 7. The inner side of the base 61 is pressed against the outer surface of the embedded part 4 and the two mold-forming bodies 21. The height of the positioning rod 3 can be adjusted by the telescopic action of the telescopic adjustment assembly 62. Furthermore, the inner side of the base 61 is pressed against the outer surface of the embedded part 4 and the two mold-forming bodies 21 to prevent grout leakage.

[0043] Furthermore, such as Figure 10 As shown, in this embodiment, the telescopic adjustment assembly 62 includes a lower screw 621, an upper screw 622, and a threaded sleeve 623 with opposite internal thread directions at both ends. The bottom end of the lower screw 621 is connected to the base 61, and its top end is threadedly connected to the bottom end of the threaded sleeve 623. The bottom end of the upper screw 622 is threadedly connected to the top end of the threaded sleeve 623, and its top end is connected to the outer protrusion 7. The overall length of the telescopic adjustment assembly 62 can be adjusted by rotating the threaded sleeve 623, thereby adjusting the height of the positioning rod 3.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
