Description

Technical Field

[0001] This application relates to the field of exterior wall installation technology, and in particular to a prefabricated exterior wall installation and positioning device. Background Technology

[0002] During the installation of exterior walls, the hoisting and placement of prefabricated wall components is a crucial step that affects the construction progress and quality control of prefabricated buildings. This is especially true since most projects use a large number of prefabricated exterior walls, making the impact even more pronounced.

[0003] Currently, the hoisting of prefabricated walls in domestic prefabricated buildings often involves first hoisting them into position. During this process, to ensure the prefabricated wall aligns with the pre-embedded positioning steel bars in the ground, workers typically need to kneel on the ground to observe the position of the positioning holes on the bottom of the prefabricated wall. They then work with other workers to continuously adjust the position of the prefabricated wall until the positioning holes align with the positioning steel bars, thus completing the subsequent precise installation. This calibration process consumes a significant amount of time and substantially impacts the completion progress of the vertical component hoisting. Therefore, further improvements are warranted. Utility Model Content

[0004] In order to simplify the installation of prefabricated exterior walls and improve their installation efficiency, this application provides a prefabricated exterior wall installation and positioning device.

[0005] The prefabricated exterior wall installation and positioning device provided in this application adopts the following technical solution:

[0006] A prefabricated exterior wall installation and positioning device includes a positioning bracket fixedly installed on the ground, a positioning guide rail installed on the positioning bracket, and a positioning rod installed on the prefabricated exterior wall. The positioning guide rail is vertically fixedly installed on the side of the positioning bracket facing the installation point of the exterior wall, and the positioning rod is vertically and detachably fixedly installed on the back side of the prefabricated exterior wall. The positioning rod and the positioning guide rail are paired and cooperate, and during the hoisting and lowering of the prefabricated exterior wall, the positioning rod slides and engages with the positioning guide rail as the prefabricated exterior wall is lowered.

[0007] By adopting the above technical solution, during the actual installation process, workers can pre-fix the positioning brackets according to the installation position of the precast exterior wall. As the precast exterior wall is hoisted and lowered, workers adjust its lowering posture, allowing the positioning rod to slide into the positioning guide rail. At this time, the lowering posture of the precast exterior wall is restricted and positioned by the positioning guide rail. After the precast exterior wall is fully installed in place along the positioning guide rail, the positioning holes at the bottom of the precast exterior wall can automatically align with the pre-installed positioning steel bars on the ground, eliminating the need for workers to constantly observe and adjust the positioning holes and pre-installed positioning steel bars at the bottom of the precast exterior wall. This greatly simplifies the installation work of the precast exterior wall and improves its installation efficiency. In addition, in the traditional installation process, after the precast exterior wall is positioned, lowered, and installed, it is necessary to install corresponding diagonal braces to support and fix the precast exterior wall. However, this application can use the positioning brackets to simultaneously support the precast exterior wall after it is lowered and installed, further simplifying the actual installation work of the precast exterior wall.

[0008] Optionally, the positioning bracket includes a support base and a support side frame. The support base is provided with connecting ears for connecting and fixing to the ground. An inclined support rod connects the support base and the support side frame.

[0009] By adopting the above technical solution, the positioning bracket is connected to the ground through connecting ears. At the same time, with the help of the inclined support rod, the overall structural stability of the entire positioning bracket can be further improved, so as to ensure the stability of subsequent support for the prefabricated exterior wall.

[0010] Optionally, the number of positioning guide rails is two sets, and they are respectively installed on the left and right sides of the positioning bracket.

[0011] By adopting the above technical solution and utilizing two sets of positioning guide rails, the stability of the positioning, installation and lowering process of the prefabricated exterior wall and the subsequent support stability of the prefabricated exterior wall can be further improved.

[0012] Optionally, the inlet of the internal slide of the positioning guide rail is chamfered.

[0013] By adopting the above technical solution, and by forming a chamfer at the entrance of the internal slide of the positioning guide rail, it is possible for workers to quickly insert the positioning rods on the prefabricated exterior wall into the positioning guide rail during the lowering process, which facilitates the actual installation operation.

[0014] Optionally, the positioning rod is in the form of a hollow tube.

[0015] By adopting the above technical solution and further hollowing out the positioning rod, the overall weight of the positioning rod is reduced, which facilitates the installation and disassembly of the positioning rod by workers.

[0016] Optionally, a damping element is installed on the positioning bracket, and the damping element is horizontally arranged and installed below the positioning guide rail.

[0017] By adopting the above technical solution, during the hoisting and lowering installation of the precast exterior wall along the positioning guide rail, as the precast exterior wall is lowered, the bottom of the positioning rod protrudes from the bottom of the positioning guide rail and is then supported on the damping component. At this time, the damping component can assist in the lowering, further improving the stability of the precast exterior wall during installation. Furthermore, if the hoisted precast exterior wall accidentally detaches from the slings and falls freely during this process, the damping component can cushion the free fall of the precast exterior wall, making it less likely to violently impact the ground, thus further ensuring the safety of the installation process.

[0018] Optionally, the damping component includes a lower support plate, an upper support plate, and an elastic component installed between the lower support plate and the upper support plate. The lower support plate is fixedly installed on the positioning bracket, and the upper support plate is floating.

[0019] By adopting the above technical solution, during the lowering process of the precast exterior wall, when the positioning rod is supported by the upper support plate in the damping component, the elastic component between the lower support plate and the upper support plate is compressed to achieve buffering.

[0020] Optionally, a protective rubber pad is provided on the top of the upper support plate, and the protective rubber pad is arranged and installed directly below the positioning guide rail.

[0021] By adopting the above technical solution and setting protective pads, when the positioning rod comes into contact with the damping component, the protective pads can isolate and protect it. At this time, the positioning rod will not make direct rigid contact with the upper support plate in the damping component and deform, so as to better protect the bottom end of the positioning rod, so that the positioning rod can be smoothly inserted and matched with the positioning guide rod when used again in the future.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In the actual installation process, workers can pre-fix the positioning brackets according to the installation position of the precast exterior wall. As the precast exterior wall is hoisted and lowered, the workers adjust the lowering posture of the precast exterior wall so that the positioning rod slides into the positioning guide rail. At this time, the lowering posture of the precast exterior wall is restricted and positioned by the positioning guide rail. After the precast exterior wall is fully installed in place along the positioning guide rail, the positioning hole at the bottom of the precast exterior wall can automatically align with the pre-installed positioning steel bars on the ground. This eliminates the need for workers to observe the positioning hole at the bottom of the precast exterior wall and the pre-installed positioning steel bars on the ground in real time and make various adjustments, which greatly simplifies the installation work of the precast exterior wall and improves its installation efficiency. In addition, in the traditional installation process, after the precast exterior wall is positioned and lowered, it is necessary to install corresponding diagonal braces to support and fix the precast exterior wall. However, this application can use the positioning brackets to support the precast exterior wall at the same time after it is lowered and installed, which can further simplify the actual installation work of the precast exterior wall.

[0024] 2. By further hollowing out the positioning rod, the overall weight of the positioning rod is reduced, which makes it easier for workers to install and disassemble the positioning rod;

[0025] 3. During the hoisting and lowering installation of the precast exterior wall along the positioning guide rails, as the precast exterior wall is lowered, the bottom of the positioning rod protrudes from the bottom of the positioning guide rails and is then supported by the damping component. At this time, the damping component assists in the lowering, further improving the stability of the precast exterior wall during installation. Additionally, if the hoisted precast exterior wall accidentally detaches from the slings and falls freely, the damping component can cushion the free fall, preventing a violent impact with the ground and further ensuring the safety of the installation process.

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a prefabricated exterior wall installation and positioning device.

[0032] Reference Figure 1 A prefabricated exterior wall installation and positioning device includes a positioning bracket 1 fixedly installed on the ground, a positioning guide rail 2 installed on the positioning bracket 1, and a positioning rod 3 installed on the prefabricated exterior wall 100, wherein the positioning guide rail 2 and the positioning rod 3 are paired. The positioning guide rail 2 is fixedly installed on the side of the positioning bracket 1 facing the installation point on the exterior wall. In this embodiment, there are two sets of positioning guide rails 2, both vertically arranged and respectively on the left and right sides. Correspondingly, the positioning rod 3 is fixedly installed on the back side of the prefabricated exterior wall 100. There are also two sets of positioning rod 3, both vertically arranged and respectively on the left and right sides, and each set of positioning rod 3 corresponds to one set of positioning guide rail 2.

[0033] During actual installation, workers can pre-fix the positioning bracket 1 according to the installation position of the precast exterior wall 100. As the precast exterior wall 100 is hoisted and lowered, the workers adjust the lowering posture of the precast exterior wall 100 so that the positioning rod 3 slides into the positioning guide rail 2. At this time, the lowering posture of the precast exterior wall 100 is restricted and positioned by the positioning guide rail 2. After the precast exterior wall 100 is fully installed in place along the positioning guide rail 2, the positioning hole at the bottom of the precast exterior wall 100 can automatically align with the pre-installed positioning steel bars on the ground. This eliminates the need for workers to observe the positioning hole at the bottom of the precast exterior wall 100 and the pre-installed positioning steel bars on the ground in real time and make various adjustments, which greatly simplifies the installation work of the precast exterior wall 100 and improves its installation efficiency.

[0034] In addition, in the traditional installation process, after the prefabricated exterior wall 100 is positioned and lowered, it is necessary to install corresponding diagonal braces to support and fix the prefabricated exterior wall 100. However, in this application, after the prefabricated exterior wall 100 is lowered and installed, the positioning bracket 1 can be used to support the prefabricated exterior wall 100 at the same time, which can further simplify the actual installation work of the prefabricated exterior wall 100.

[0035] In this embodiment, the positioning rod 3 is installed and fixed to the prefabricated outer wall 100 by pre-embedded bolts and matching nuts to achieve detachable installation, which will not be described in detail here.

[0036] Specifically, in this embodiment, the positioning bracket 1 includes a supporting base 11 and supporting side frames 12; the supporting base 11 is provided with connecting ears 13 for connecting and fixing to the ground. An inclined support rod 14 connects the supporting base 11 and the supporting side frames 12 to improve the connection strength between the supporting base 11 and the supporting side frames 12, thereby improving the overall structural stability of the entire positioning bracket 1 and ensuring the stability of subsequent support for the precast exterior wall 100.

[0037] In this embodiment, the positioning rod 3 is a hollow tube to reduce its overall weight, thereby facilitating the installation and disassembly of the positioning rod 3 by workers. The inlet of the internal slide of the positioning guide rail 2 is chamfered to facilitate quick insertion of the positioning rod 3 on the prefabricated exterior wall 100 into the positioning guide rail 2 during the lowering process of the prefabricated exterior wall 100, thus facilitating the actual installation operation.

[0038] Reference Figure 1 In this embodiment, a damping component 4 is also installed on the positioning bracket 1. The damping component 4 is horizontally arranged and installed below the positioning guide rail 2.

[0039] Reference Figure 2 The damping component 4 includes a lower support plate 41, an upper support plate 42, and an elastic component 43 installed between the lower support plate 41 and the upper support plate 42. In this embodiment, the elastic component 43 is a spring. The elastic component 43 is arranged at intervals along the length direction of the lower support plate 41 and the upper support plate 42, and the upper and lower ends of the elastic component 43 are fixedly connected to the lower support plate 41 and the upper support plate 42, respectively. The lower support plate 41 and the upper support plate 42 are both horizontally arranged, and the lower support plate 41 is fixedly installed on the positioning bracket 1, while the upper support plate 42 is floating.

[0040] During the hoisting and lowering installation of the precast exterior wall 100 along the positioning guide rail 2, as the precast exterior wall 100 is lowered, the bottom of the positioning rod 3 protrudes from the bottom of the positioning guide rail 2 and is then supported on the damping member 4. At this time, the elastic component 43 between the lower support plate 41 and the upper support plate 42 is compressed to achieve buffering, thereby assisting the lowering with the help of the damping member 4 and further improving the stability of the lowering and installation of the precast exterior wall 100. In addition, during this process, if the hoisted precast exterior wall 100 accidentally detaches from the sling and falls freely, the damping member 4 can buffer the free fall of the precast exterior wall 100, making it less likely to have a violent impact with the ground, thereby further ensuring the safety of this installation process.

[0041] In other embodiments, the elastic member 43 may be an elastic structural member with a buffering effect, such as a damping rod.

[0042] Reference Figure 2In this embodiment, a protective pad 5 is provided on the top of the upper support plate 42, and the protective pad 5 is arranged and installed directly below the positioning guide rail 2. By providing the protective pad 5, when the positioning rod 3 comes into contact with the damping member 4, the protective pad 5 can isolate and protect it. At this time, the positioning rod 3 will not make direct rigid contact with the upper support plate 42 in the damping member 4 and deform, so as to better protect the bottom end of the positioning rod 3, so that the positioning rod 3 can be smoothly inserted and matched with the positioning guide rod when used again in the future.

[0043] The implementation principle of the prefabricated exterior wall installation and positioning device in this application embodiment is as follows: During the actual installation process, the worker can pre-fix the positioning bracket 1 according to the installation position of the prefabricated exterior wall 100. As the prefabricated exterior wall 100 is hoisted and lowered, the worker adjusts the lowering posture of the prefabricated exterior wall 100 so that the positioning rod 3 slides into the positioning guide rail 2. At this time, the lowering posture of the prefabricated exterior wall 100 is restricted and positioned by the positioning guide rail 2. After the prefabricated exterior wall 100 is fully installed in place along the positioning guide rail 2, the positioning hole at the bottom of the prefabricated exterior wall 100 can automatically align with the pre-installed positioning steel bars on the ground without the need for the worker to observe the positioning hole at the bottom of the prefabricated exterior wall 100 and the pre-installed positioning steel bars on the ground in real time to make various adjustments. This can greatly simplify the installation work of the prefabricated exterior wall 100 and improve its installation efficiency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
