Description

Technical Field

[0001] The utility model belongs to the field of building construction structures, and in particular relates to a wire box veneer positioning rib reinforcement structure. Background Art

[0002] During the construction of reinforced concrete shear walls, it is necessary to pre-embed the wire box in advance to facilitate the subsequent installation of the corresponding pipelines. The usual practice for pre-embedded wire box installation is: the wire box uses a finished reinforcing wire box purchased from the market, with a reinforcing hole reserved at the top and bottom, and the steel bars matching the reinforcing holes are inserted into them, and the inserted upper and lower steel bars are tied and fixed to the shear wall steel bars.

[0003] The traditional method of pre-embedded wire box is to fix it by tying two upper and lower steel bars to the shear wall steel bars. However, this method can only ensure the fixed position of the wire box on one side of the shear wall, and cannot ensure the precise limit position in the shear wall space. Under the traditional method, the veneer condition of the wire box and the inside of the shear wall formwork depends on whether the shear wall steel bar binding itself is horizontal and vertical and whether the positioning and installation position is within the allowable deviation range. Otherwise, it cannot ensure that the veneer rate of the wire box and the inside of the shear wall formwork is 100%, and the quality of pre-embedded molding is not controlled. Summary of the invention

[0004] The utility model aims to solve the problem in the prior art that the pre-embedded wire box is difficult to fit the shear wall formwork, and to provide a wire box surface positioning rib reinforcement structure.

[0005] The specific technical solutions adopted by this utility model are as follows:

[0006] A wire box veneer positioning reinforcement structure is used for positioning and installing a reinforcement wire box in a shear wall steel mesh. The top and bottom surfaces of the reinforcement wire box are provided with reinforcement reserved holes, and the reinforcement wire box includes two first vertical measure bars, two second vertical measure bars, two horizontal measure bars and two special-shaped positioning bars.

[0008] Two horizontal measure bars pass through the reinforcement holes on the top and bottom of the reinforcement box respectively, and are tied and fixed to the second vertical measure bars on both sides of the reinforcement box;

After the horizontal steel bar segment is tied and fixed to the first vertical measure bar, the other end extends out of the shear wall steel mesh, and the distance from the other end of the horizontal steel bar segment to the front of the reinforcement wire box is equal to the spacing between the templates on both sides of the shear wall; the angle structure of the two special-shaped positioning bars is respectively clamped on two different horizontal measure bars.

[0010] Preferably, the vertical reinforcement segment of the special-shaped positioning reinforcement reuses the second vertical measure reinforcement.

[0011] Preferably, the horizontal steel bar segments and the vertical steel bar segments in the special-shaped positioning bars are fixed vertically.

[0012] Preferably, the horizontal steel bar segments and the vertical steel bar segments in the special-shaped positioning bars are fixed by welding.

[0015] Preferably, the first vertical measure reinforcement is fixed to the horizontal distribution reinforcement by tying with wire.

[0016] Preferably, the second vertical measure reinforcement is fixed to the horizontal distribution reinforcement by tying with wire.

[0017] Preferably, the horizontal steel bar segment of the special-shaped positioning reinforcement is fixed to the first vertical measure reinforcement by binding with wire.

[0018] Preferably, the binding wires used for binding and fixing are all 22# binding wires.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model proposes to add a special-shaped positioning reinforcement structure on the basis of the traditional pre-buried installation method of the wire box through the reinforcement, so as to realize the precise positioning and limiting of the wire box in the shear wall space.

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0028] In the description of the present utility model, it is necessary to understand that when an element is considered to be "connected" to another element, it can be directly connected to another element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0029] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0030] In a preferred embodiment of the present invention, a wire box veneer positioning reinforcement structure is provided, which is used to position and install a wire box 5 in the shear wall steel mesh to solve a series of construction pain points in the traditional wire box pre-embedded installation, such as the wire box part needs to be corrected by secondary chiseling, secondary plastering, and secondary installation of heightening rings due to the poor veneer rate and uncontrolled pre-embedded molding quality. The wire box 5 used in the present invention can be a finished wire box, and both the top and bottom surfaces have reserved holes 6 for ribs. Figure 1 As shown, the junction box veneer positioning rib reinforcement structure of the utility model includes two first vertical measure ribs 1, two second vertical measure ribs 2, two horizontal measure ribs 3 and two special-shaped positioning ribs 4. The core is to add special-shaped positioning rib reinforcement structure on the basis of traditional practices to achieve precise positioning of the junction box in the shear wall space and achieve 100% veneer rate between the junction box and the inner side of the shear wall formwork.

[0031] Continue to see Figure 1 As shown, the steel mesh inside the shear wall belongs to the prior art, which is formed by binding horizontal distribution bars and vertical distribution bars, wherein the horizontal distribution bars and vertical distribution bars in the shear wall steel mesh are distributed on the side close to the front of the wire box (i.e. the side of the wire box with an opening) and the side close to the back of the wire box. Two first vertical measure bars 1 are arranged on both sides of the reinforcement wire box 5, and are bound and fixed on the horizontal distribution bars of the shear wall steel mesh on the left and right sides of the back of the wire box. In order to ensure the reliability of binding and fixing, each first vertical measure bar 1 needs to be bound and fixed on at least two horizontal distribution bars, preferably using 22# binding wire for binding and fixing.

[0032] In addition, two second vertical measure bars 2 are also arranged on both sides of the reinforcement box 5, and are tied and fixed to the horizontal distribution bars of the shear wall steel mesh on the left and right sides of the front of the box. Similarly, in order to ensure the reliability of the tying and fixing, each second vertical measure bar 2 needs to be tied and fixed to at least two horizontal distribution bars.

[0033] The top and bottom surfaces of the finished reinforcing bar box 5 are provided with pre-reserved holes 6 for reinforcing bar insertion, so one horizontal measure bar 3 passes through the pre-reserved hole 6 for reinforcing bar insertion on the top surface of the reinforcing bar box 5, while the other horizontal measure bar 3 passes through the pre-reserved hole 6 for reinforcing bar insertion on the bottom surface of the reinforcing bar box 5. The two horizontal measure bars 3 can be respectively tied and fixed on the second vertical measure bars 2 on both sides of the reinforcing bar box 5, so as to relatively fix the reinforcing bar box 5 inside the shear wall steel mesh. However, due to the inevitable errors in the actual construction on site, the fixation of the reinforcing bar box 5 at this time is only a preliminary fixation with very low precision. When the shear wall steel mesh is tilted as a whole or some of the steel bars therein are tilted, it often causes the front of the reinforcing bar box 5 to not fit well with the concrete casting formwork of the shear wall. In this case, pouring concrete will cause the front of the reinforcing bar box 5 to be covered in concrete, and the molding quality is out of control. Therefore, the utility model further introduces two special-shaped positioning ribs 4 arranged on both sides of the reinforcement box 5 to ensure the veneer rate between the front side of the reinforcement box 5 and the inner side of the shear wall formwork.

[0034] Continue to see Figure 1 As shown, each special-shaped positioning bar 4 is formed by a horizontal steel bar segment and a vertical steel bar segment cross-fixed, and the end of the horizontal steel bar segment is extended relative to the fixed position, and the extended segment and the vertical steel bar segment form an angle structure for locking and positioning. It should be noted that the end of the horizontal steel bar segment must be extended relative to the fixed position to ensure that the extended segment and the vertical steel bar segment form an angle structure, but the end of the vertical steel bar segment does not necessarily need to be extended relative to the fixed position. Figure 2 As shown in FIG. 1 , both the horizontal reinforcement segment and the vertical reinforcement segment have extension segments at fixed positions, and as shown in FIG. Figure 3 As shown, it shows a form in which only the horizontal reinforcement segment has an extension segment but the vertical reinforcement segment does not have an extension segment. Both methods are feasible.

[0035] It should be noted that the horizontal steel bar segment and the vertical steel bar segment in the special-shaped positioning bar 4 are preferably fixed vertically, but in theory, it is also feasible that the two are not completely vertical. However, for the reliability of quality control during processing and construction, the two steel bars are preferably fixed vertically as much as possible.

[0036] It should also be noted that, in theory, there is no limit to the fixing form between the horizontal steel bar segment and the vertical steel bar segment. For example, welding or fixing with connectors such as snaps are all feasible, as long as the fixing strength can be guaranteed. Taking into account the processing cost and reliability, the two can be fixed directly by welding. The end of the horizontal steel bar segment is extended relative to the welding position, which can be adjusted by adjusting the welding position of the vertical steel bar segment on the horizontal steel bar segment, that is, the vertical steel bar segment cannot be directly welded to the end position of the horizontal steel bar segment, but needs to maintain a certain distance from the end position of the horizontal steel bar segment, so that a small section of the horizontal steel bar segment extends out of the welding position to form an extended section. The above-mentioned two special-shaped positioning bars 4 can be pre-processed in batches in the factory, and can be directly assembled and fixed after being transported to the site.

[0037] Continue to see Figure 1 As shown, the two ends of the vertical steel bar segment of each special-shaped positioning bar 4 are respectively tied and fixed on the two horizontal measure bars 3. For the convenience of description, the two ends of the horizontal steel bar segment are respectively referred to as one end and the other end, the former refers to the end of the extension segment, and the latter refers to the other end. When the special-shaped positioning bar 4 is assembled, the end of the extension segment at one end of the horizontal steel bar segment is retracted relative to the front of the reinforcing wire box 5 to ensure that when the front of the reinforcing wire box 5 is attached to the inner wall of the shear wall formwork, the end of the extension segment at one end of the horizontal steel bar segment will not interfere with the shear wall formwork. After the horizontal steel bar segment is tied and fixed to the first vertical measure bar 1, the other end extends out of the shear wall steel mesh, and the distance from the other end of the horizontal steel bar segment to the front of the reinforcement wire box 5 is equal to the spacing between the templates on both sides of the shear wall. Therefore, during the mold closing process of the templates on both sides of the shear wall, the template on one side will push the other end of the horizontal steel bar segment, and through the conduction of the special-shaped positioning bar 4, the first vertical measure bar 1, the second vertical measure bar 2, the horizontal measure bar 3 and the shear wall steel mesh will be deformed and displaced to a certain extent, so that the front of the reinforcement wire box 5 can just fit the inner wall of the template on the other side, thereby ensuring 100% veneer rate of the wire box and achieving one-time excellent quality of pre-embedded molding.

[0038] In addition, see Figure 1 As shown, the angle structure of the two special-shaped positioning ribs 4 should be respectively clamped on two different horizontal measure ribs 3, so that the two special-shaped positioning ribs 4 can simultaneously apply thrust to the two horizontal measure ribs 3 to ensure that the upper and lower sides of the wire box 5 are subjected to force at the same time and shift synchronously.

[0039] It should be noted that the reinforcing wire box 5 in the present invention can be a single independent box body, or a plurality of box bodies arranged side by side, which is not limited here.

[0040] It should be noted that in the embodiment of the present invention, the first vertical measure bar 1 is fixed to the horizontal distribution bar by tying wire, the second vertical measure bar 2 can also be fixed to the horizontal distribution bar by tying wire, and the horizontal steel bar segment of the special-shaped positioning bar 4 can also be fixed to the first vertical measure bar 1 by tying wire. The tying wire used for tying and fixing each steel bar can be adjusted according to the actual strength requirements, preferably 22# tying wire.

[0041] In addition, since the special-shaped positioning bars 4 of the utility model are subjected to thrust during the process of closing the templates on both sides of the shear wall, the vertical steel bar segments of the two special-shaped positioning bars 4 will also exert thrust on the two second vertical measure bars 2. In order to ensure the reliability of thrust transmission, the vertical steel bar segments of the two special-shaped positioning bars 4 are preferably fitted and fixed to the side of the two second vertical measure bars 2 away from the front of the reinforcement wire box 5, that is, the force of the vertical steel bar segments can be directly transmitted to the second vertical measure bars 2. However, if the vertical steel bar segments of the two special-shaped positioning bars 4 are fixed to the side of the two second vertical measure bars 2 close to the front of the reinforcement wire box 5, the force needs to be transmitted by the binding wire, which is prone to quality defects when the strength of the binding wire is insufficient.

[0042] In addition, in another embodiment of the present invention, there is also provided a Figure 1 The deformation structure of the wire box surface positioning rib reinforcement structure shown. Figure 1 In the structure shown, the structural form of the special-shaped positioning rib 4 is similar to a "7" shape or an L shape. Figure 4 As shown, in this deformation form, the vertical steel bar segment of the special-shaped positioning rib 4 reuses the second vertical measure rib 2. In other words, the vertical steel bar segment of the special-shaped positioning rib 4 does not need to be set independently, but the two second vertical measure ribs 2 are directly used as the vertical steel bar segments of the two special-shaped positioning ribs 4, and the horizontal steel bar segments of the two special-shaped positioning ribs 4 are directly welded to the two second vertical measure ribs 2, so as to form a "T"-shaped positioning rib 7 that is a composite of the second vertical measure rib 2 and the special-shaped positioning rib 4. This "T"-shaped positioning rib 7 can also realize the vertical and horizontal positioning and limiting of the wire box to ensure the purpose of wire box veneer, and relative to Figure 1 The "7"-shaped or L-shaped special-shaped positioning reinforcement 4 shown can also greatly reduce the investment in vertical measure reinforcement, improve construction efficiency and reduce construction costs.

[0043] In summary, the utility model proposes a wire box veneer positioning rib reinforcement structure, which is used to position and install the wire box with reinforcement in the shear wall steel mesh. The utility model adds a special-shaped positioning rib reinforcement structure on the basis of the traditional pre-embedded installation method of the wire box with reinforcement, so as to achieve accurate positioning and limiting of the wire box in the shear wall space, and utilizes its own good structural rigidity to achieve the process of template closing by squeezing the special-shaped positioning ribs to ensure that the wire box is 100% veneered on the inner side of the template, so as to achieve the best quality of pre-embedded molding in one go. The utility model has a simple structure and is easy to install, which solves a series of construction pain points in the traditional pre-embedded installation of wire boxes, such as the need for secondary chiseling and correction, secondary plastering and closing, and secondary installation of heightening rings, etc., due to the poor veneer rate leading to uncontrolled pre-embedded molding quality.

[0044] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
