Abstract
Description
Technical Field
[0001] This utility model relates to the field of precast wall technology, and more specifically, to a precast wall panel. Background Technology
[0002] Precast wall panels are pre-manufactured wall panels that can be quickly installed on the construction site, effectively saving time and improving production efficiency. Precast wall panels are usually made of raw materials such as concrete, sand, gravel, and aggregates, and their appearance and performance are similar to ordinary brick walls. During installation, precast wall panels need to be fixed to the pre-embedded steel bars and steel columns on the ground of the construction site.
[0003] Precast wall panels typically consist of the panel body, anchoring steel bars, and grouting sleeves. When hoisting precast wall panels, the embedded steel bars need to be inserted into the grouting sleeves. Subsequently, concrete is poured into the grouting sleeves to fix the precast wall panels to the embedded steel bars. The anchoring steel bars are used to tie the precast wall panels to the steel columns on the construction site to complete the connection between the precast wall panels and the adjacent walls.
[0004] However, since the existing anchoring steel bars are all fixed to the wall panel body, the anchoring steel bars will interfere with the steel column during the process of aligning the grouting sleeve with the pre-embedded steel bars. In actual production, before hoisting the precast wall panel, it is necessary to manually bend the anchoring steel bars at a certain angle to reduce the possibility of interference with the steel column. When fixing the anchoring steel bars to the steel column, it is necessary to bend the anchoring steel bars again, which is time-consuming and labor-intensive.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated wall panel.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a precast wall panel, comprising a wall panel body and anchoring steel bars, wherein the anchoring steel bars include a fixing part and an adjusting part, wherein the fixing part includes a hollow round rod arranged along the height direction of the wall panel body, and the adjusting part includes a long rod rotatably connected in the hollow round rod and an L-shaped frame for binding steel columns, wherein a groove is provided on the outer peripheral wall of the hollow round rod, and the end of the L-shaped frame passes through the groove and is welded to the long rod, wherein the adjusting part is provided with a limiting member having one end passing through the groove and threadedly connected to the long rod, the limiting member being used to limit the relative rotation between the long rod and the hollow round rod.
[0008] The present invention is further configured such that: the fixing part further includes a plurality of skeleton steel bars fixed in the wall panel body, the ends of the skeleton steel bars protruding on the side wall of the wall panel body, and the hollow round rod is welded to the ends of the skeleton steel bars.
[0009] The present invention is further configured such that the number of the limiting members is less than the number of the L-shaped frame.
[0010] The present invention is further configured such that the outer diameter of the long rod is smaller than the inner diameter of the hollow round rod.
[0011] The present invention is further configured such that a deformation groove is provided at the bend of the L-shaped frame.
[0012] The present invention is further configured such that the L-shaped frame is made of Q235 steel.
[0013] In summary, this utility model has the following beneficial effects:
[0014] Before hoisting the precast wall panels, the construction workers first remove the restrictive parts, allowing the long rod to rotate within the hollow round rod. When coordinating the hoisting of the precast wall panels with the embedded steel bars, rotating the round rod allows the L-shaped frame to slide along the groove, thus preventing the adjustment part from interfering with the steel columns on the construction site. This rotation method reduces the possibility of interference between the anchored steel bars and the steel columns. Compared to the existing method of manually bending the anchored steel bars, the above method is more labor-saving. Moreover, when the long rod is rotated, all L-shaped frames welded to the same long rod will rotate synchronously, making the angle adjustment of the L-shaped frame more time-saving.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] A type of precast wall panel, such as Figure 1As shown, the wall panel includes a wall panel body 1 and anchoring reinforcement bars. The anchoring reinforcement bars include a fixing part and an adjusting part. The fixing part includes a hollow round rod 2 arranged along the height direction of the wall panel body 1. The adjusting part includes a long rod 3 rotatably connected in the hollow round rod 2 and an L-shaped frame 4 for binding steel columns. A groove 5 is provided on the outer peripheral wall of the hollow round rod 2. The end of the L-shaped frame 4 passes through the groove 5 and is welded to the long rod 3. The adjusting part is provided with a limiting member 6, one end of which passes through the groove 5 and is threadedly connected to the long rod 3. The limiting member 6 is used to limit the relative rotation between the long rod 3 and the hollow round rod 2. Before hoisting the precast wall panel, the construction personnel first remove the limiting member 6 so that the long rod 3 can rotate in the hollow round rod 2. When the precast wall panel is hoisted and coordinated with the embedded reinforcement bars, the L-shaped frame 4 can slide along the groove 5 by rotating the round rod, so that the adjusting part is less likely to interfere with the steel columns on the construction site. The operation method reduces the possibility of interference between the anchoring steel bars and the steel column. Compared with the existing method of manually bending the anchoring steel bars, the above setting is more labor-saving. Moreover, when the long rod 3 is rotated, the L-shaped frames 4 welded to the same long rod 3 will all rotate synchronously, making the angle adjustment of the L-shaped frames 4 more time-saving. After the precast wall panel is hoisted, the long rod 3 is rotated again to make the L-shaped frames 4 contact the steel column. After the L-shaped frames 4 are tied to the steel column, the previously disassembled limiting parts 6 are reinstalled on the adjustment part, making it less likely for the L-shaped frames 4 to rotate relative to the hollow round rod 2. This can better ensure the stability of the connection between the L-shaped frames 4 and the steel column, and facilitate the subsequent grouting and fixing of the anchoring steel bars and the steel column. In addition, the limitation of the long rod 3 in the hollow round rod 2 by the limiting parts 6 can also reduce the possibility of the adjustment part colliding with other precast wall panels and other objects during the transportation of the precast wall panel.
[0020] like Figure 1 and Figure 2As shown, the fixing part also includes several skeleton steel bars 7 fixed in the wall panel body 1. The ends of the skeleton steel bars 7 are exposed on the side wall of the wall panel body 1. The hollow round rod 2 is welded to the ends of the skeleton steel bars 7. Specifically, the wall panel body 1 is prefabricated by a mold. When prefabricating the wall panel body 1, the skeleton steel bars 7 are placed in the mold together, with both ends of the skeleton steel bars 7 exposed on both sides of the mold. After the wall panel body 1 solidifies, the hollow round rod 2 with the groove 5 is welded to the skeleton steel bars 7. On the one hand, the skeleton steel bars 7 can ensure the strength of the wall panel body 1. On the other hand, the skeleton steel bars 7 can ensure the connection strength between the hollow round rod 2 and the wall panel body 1. The number of limiting parts 6 is less than the number of L-shaped frames 4. Reducing the number of limiting parts 6 can reduce the number of times the construction personnel need to install the limiting parts 6 without affecting the degree of freedom of rotation of the long rod 3 in the hollow round rod 2, thereby effectively improving the efficiency of prefabricated wall panel installation. The outer diameter of the long rod 3 is smaller than that of the hollow round rod. The inner diameter of rod 2 is reduced, which decreases the contact area between the long rod 3 and the hollow round rod 2, reducing the relative friction between them when the long rod 3 rotates. This makes rotating the long rod 3 easier. Furthermore, during subsequent grouting to fix the anchor bars and steel columns, mortar can enter the hollow round rod 2 through the gap between the hollow round rod 2 and the long rod 3. After the mortar solidifies, the possibility of the long rod 3 rotating within the hollow round rod 2 is further reduced, thus better ensuring the subsequent precast wall panels and... To ensure the stability of the steel column fixing, deformation grooves 8 are provided at the bends of the L-shaped frame 4. The deformation grooves 8 make it easy for the L-shaped frame 4 to deform at the bends, which facilitates the construction personnel to tie the L-shaped frame 4 to the steel column. The L-shaped frame 4 is made of Q235 steel, which has good ductility. When the L-shaped frame 4 made of this material is tied to the steel column, it can undergo greater deformation, thereby increasing the contact area between the L-shaped frame 4 and the steel column and improving the stability of the anchoring steel bars and the steel bar connection.

All technical solutions falling within the scope of this utility model's concept are protected.
