Description

Technical Field

[0001] This invention relates to a rebar tying platform device, and more particularly to a rebar tying platform device for non-vertical concrete walls. Background Technology

[0002] Currently, when the height of a reinforced concrete wall exceeds 2 meters, a rebar tying platform needs to be erected to assist in the rebar tying construction. There are various construction techniques or auxiliary tying devices for traditional concrete wall rebar tying, such as erecting precast frames for precast rebar mesh installation, erecting external disc-type or cup-type scaffolding for rebar mesh tying, and erecting internal disc-type or cup-type scaffolding work platforms for rebar tying. The above-mentioned wall reinforcement construction techniques or tools are mainly for vertical or near-vertical internal reinforcement wall binding, where there are conditions for setting up a construction platform inside or outside the reinforcement wall, or where the reinforcement binding does not have very strict requirements and prefabricated mesh can be used for overall binding construction. However, the existing disc-lock scaffolding or bowl-lock scaffolding construction platforms are not suitable for non-vertical walls, especially for reinforcement walls where the horizontal main reinforcement is located inside the vertical reinforcement. Even if they are usable, installation and dismantling are cumbersome and delay the construction period. While setting up a prefabricated reinforcement binding frame for prefabrication and overall installation of reinforcement mesh is relatively usable, it is not suitable for reinforcement mesh installation with large diameter reinforcement, high installation quality requirements, straight threaded sleeve connection or other mechanical connection methods. Centering the reinforcement mesh is very difficult.

[0003] In recent years, with social development, various rebar tying construction techniques have been further improved and optimized, and the requirements for rebar tying accuracy, installation quality, and construction safety management have become increasingly stringent. For lock engineering, the lock chamber wall is a non-complete vertical structure, with horizontal rebar inside the vertical rebar and large-diameter rebar, generally requiring straight threaded sleeve connections, with no more than 2 exposed threads. These construction requirements mean that the overall installation of precast mesh does not meet the requirements for straight threaded sleeve connections. Erecting an external support platform for the wall makes it impossible to hoist the rebar, and manual transfer is time-consuming and labor-intensive. Erecting an internal support platform results in an off-center center of gravity, posing safety hazards. Furthermore, any platform erection involves cumbersome installation and dismantling, is time-consuming, and is difficult for workers to execute.

[0004] To address the above difficulties, if the wall is not completely vertical and is relatively thick, a scaffolding system can be used for rebar tying. However, in lock-like projects, most lock chamber walls are not very thick, making it impossible to erect the scaffolding system in a balanced manner, and even if erected, it poses significant safety hazards. Therefore, how to achieve rapid rebar tying while reducing the workload of scaffolding erection and manual rebar transfer has become a pressing problem to be solved in the construction of non-vertical walls. Summary of the Invention

[0005] To address the above shortcomings, this invention provides a rebar tying platform device for non-fully vertical walls that can accelerate the rebar tying process, standardize rebar tying construction, ensure construction safety, and save construction time and machinery costs.

[0006] Specifically, this application adopts the following technical solution: a non-vertical concrete wall reinforcement binding platform device, including a rectangular steel scissor brace for supporting the vertical and non-vertical wall reinforcement. The rectangular steel scissor brace is formed by the intersection of two rectangular steel bars. Bolt holes and scissor brace locking bolts are provided at the intersection of the two rectangular steel bars. The scissor brace locking bolts are inserted into the bolt holes to lock the rectangular steel scissor brace. When the rectangular steel scissor brace is unfolded, the line connecting the upper and lower ends on one side of the rectangular steel scissor brace is perpendicular to the ground and parallel to the vertical wall reinforcement. The line connecting the upper and lower ends on the other side of the rectangular steel scissor brace is parallel to the non-vertical wall reinforcement. The line connecting the upper two ends of the rectangular steel scissor brace is horizontal, and the line connecting the lower two ends of the rectangular steel scissor brace is also horizontal. A transverse pin is provided between the upper two ends of the rectangular steel scissor brace, and the transverse pin is horizontally engaged between the upper two ends of the rectangular steel scissor brace.

[0007] Furthermore, the lengths of the two rectangular steel bars of the rectangular steel scissor brace and the intersection point of the two rectangular steel bars are determined according to the shape and size of the non-vertical concrete wall structure to ensure that the rectangular steel scissor brace can match the cross-sectional shape of the non-vertical concrete wall reinforcement when locked and unfolded using scissor brace locking bolts.

[0008] Furthermore, steel reinforcement clamping pipes are provided at all four ends of the rectangular steel scissor brace. The steel reinforcement clamping pipes are used to fix the two rectangular steels of the rectangular steel scissor brace to the wall reinforcement.

[0009] Furthermore, the steel rebar clamping pipe includes a cylindrical portion for accommodating the steel rebar. The cylindrical portion has a through side opening, and each of the two sides of the side opening has an outwardly parallel extending locking portion. A fastening bolt is provided between the extending locking portions. When the fastening bolt is tightened, the diameter of the cylindrical portion can be reduced to secure the steel rebar located therein.

[0010] Furthermore, the reinforcing bar positioning steel pipes are welded to the four ends of the rectangular steel scissor brace, and the cylindrical portions of the reinforcing bar positioning steel pipes at the upper and lower ends on one side of the rectangular steel scissor brace are parallel to the vertical wall reinforcement, so that the vertical wall reinforcement can be inserted into the cylindrical portion parallelly from the side opening of the cylindrical portion; the cylindrical portions of the reinforcing bar positioning steel pipes at the upper and lower ends on the other side of the rectangular steel scissor brace are parallel to the non-vertical wall reinforcement, so that the non-vertical wall reinforcement can be inserted into the cylindrical portion parallelly from the side opening of the cylindrical portion.

[0011] Furthermore, hooks are provided at both ends of the transverse pin, and pin grooves are provided on the inner sides of the two upper ends of the rectangular steel scissor brace. When the hooks at both ends of the transverse pin are engaged in the pin grooves, the transverse pin is in a horizontal position.

[0012] Furthermore, multiple identical rectangular steel scissor braces are set along the horizontal direction, and a work platform is erected between the transverse pins of two adjacent rectangular steel scissor braces; multiple layers of rectangular steel scissor braces can be set in the vertical direction.

[0013] Furthermore, the overall shape of the multi-layer rectangular steel scissor bracing matches the overall cross-sectional shape of the non-vertical concrete wall reinforcement, and the length of the transverse pin of the upper rectangular steel scissor bracing is less than the length of the transverse pin of the lower rectangular steel scissor bracing.

[0014] A method for operating a rebar tying platform device for non-vertical concrete walls is also provided, comprising the following steps:

[0015] Step 1: Before installing the rectangular steel scissor bracing, complete the binding of the first layer of wall reinforcement within the height range of the first layer of rectangular steel scissor bracing;

[0016] Step 2: After the first layer of wall reinforcement is tied, multiple rectangular steel scissor braces are installed based on the first layer of wall reinforcement at this height to form the first layer of rectangular steel scissor brace support.

[0017] Step 3: After the first layer of rectangular steel scissor bracing is installed, steel or wooden planks are erected on it to form a working platform. The second layer of wall reinforcement is then tied using the working platform.

[0018] Step 4: After the second layer of wall reinforcement is tied, repeat steps 2 and 3 to complete the erection of the second layer of rectangular steel scissor bracing and the tying of the third layer of wall reinforcement.

[0019] Step 5: After completing all the wall reinforcement binding work, dismantle the work platform and rectangular steel scissor bracing from top to bottom.

[0020] Further, in step 2, the rectangular steel scissor brace is first opened, and then the cylindrical parts of the two locking steel pipes at the upper end of the rectangular steel scissor brace are respectively fitted onto the vertical and non-vertical wall reinforcement bars on both sides. The lower end of the rectangular steel scissor brace is in contact with the concrete ground and the bottom is kept flat. The cylindrical parts of the two locking steel pipes at the lower end of the rectangular steel scissor brace are also respectively fitted onto the vertical and non-vertical wall reinforcement bars on both sides. Then, the bolts of the locking steel pipes are tightened to prevent the locking steel pipes from falling off. Finally, the horizontal pin is engaged into the pin groove at the upper part of the rectangular steel scissor brace. Multiple rectangular steel scissor braces are installed in sequence and side by side to form the first layer of rectangular steel scissor brace support.

[0021] This device is designed using the principles of scissor bracing and disc-locking pins to create a support platform that can be hooked onto reinforcing bars. The platform is designed in layers according to the maximum height of a single reinforcing bar binding. This platform support design enables the rapid erection and dismantling of the reinforcing bar binding work platform, saving construction time. It also allows for the temporary lifting and storage of reinforcing bars on the platform, enabling workers to pick up reinforcing bars nearby for binding construction. This greatly reduces the continuous transfer of reinforcing bars, improves construction efficiency, and achieves the goal of improving quality and efficiency, thus realizing a dual improvement in economic and social benefits.

[0022] The materials used in this device are all common materials, which are easy to purchase, simple to manufacture and easy to replicate. The manufacturing and usage costs are lower compared to commonly used construction platforms such as disc-lock scaffolding.

[0023] The device is lightweight with a single layer and single piece, requiring only 1-2 workers to install and disassemble. It has a high degree of modularity and is easy and quick to install and disassemble.

[0024] This device perfectly solves the problem of the unsuitability of traditional rebar tying construction platforms, meets the requirements of standardized and prefabricated on-site construction, improves the safety of rebar tying operations, saves labor and working time, and achieves the goals of improving quality and efficiency and meeting the requirements of creating quality projects, resulting in significant economic and social benefits.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-3 As shown, the non-vertical concrete wall reinforcement binding platform device of the present invention includes a rectangular steel scissor brace 1 supported between vertical and non-vertical wall reinforcement. The rectangular steel scissor brace 1 is formed by the intersection of two rectangular steel bars. Bolt holes and scissor brace locking bolts 2 are provided at the intersection of the two rectangular steel bars. The scissor brace locking bolts 2 are inserted into the bolt holes to lock the rectangular steel scissor brace 1. The rectangular steel scissor brace 1 can be extended or retracted around the scissor brace locking bolts 2. When the rectangular steel scissor brace 1 is extended, its shape matches the cross-sectional shape of the non-vertical concrete wall reinforcement. That is, when extended, the line connecting the upper and lower ends on the left side of the rectangular steel scissor brace 1 is perpendicular to the ground and parallel to the vertical wall reinforcement; the line connecting the upper and lower ends on the right side of the rectangular steel scissor brace 1 is parallel to the non-vertical wall reinforcement. The line connecting the upper two ends of the rectangular steel scissor brace 1 is horizontal, and the line connecting the lower two ends of the rectangular steel scissor brace 1 is also horizontal.

[0033] Since the shapes of the reinforcing bars in non-vertical concrete walls vary, when designing the rectangular steel scissor brace 1, the lengths of the two rectangular steel bars and the intersection points of the two rectangular steel bars should be determined according to the shape and size of the non-vertical concrete wall structure to ensure that when the scissor brace locking bolt 2 is used to lock and unfold, it can match the cross-sectional shape of the reinforcing bars in the non-vertical concrete wall.

[0034] Steel reinforcing pipes 3 are provided at all four ends of the rectangular steel shear brace 1, such as... Figure 2 As shown, the steel rebar clamping pipe 3 includes a cylindrical part for accommodating the steel rebar. The cylindrical part has a through side opening, and each of the two sides of the side opening has an outwardly parallel extending locking part. A fastening bolt is provided between the extending locking parts. When the fastening bolt is tightened, the diameter of the cylindrical part can be reduced to fasten the steel rebar located therein.

[0035] In one embodiment, the reinforcing bar clamping steel pipes 3 are welded to the four ends of the rectangular steel scissor brace 1, and the cylindrical portions of the reinforcing bar clamping steel pipes 3 at the upper and lower ends on the left side of the rectangular steel scissor brace 1 are parallel to the vertical wall reinforcing bars, so that the vertical wall reinforcing bars can be inserted into the cylindrical portion parallelly from the side opening of the cylindrical portion; the cylindrical portions of the reinforcing bar clamping steel pipes 3 at the upper and lower ends on the right side of the rectangular steel scissor brace 1 are parallel to the non-vertical wall reinforcing bars, so that the non-vertical wall reinforcing bars can be inserted into the cylindrical portion parallelly from the side opening of the cylindrical portion.

[0036] like Figure 3-4As shown, it also includes a transverse pin 4, with hooks at both ends. Pin grooves are provided on the inner sides of the two upper ends of the rectangular steel scissor brace 1. When the hooks at both ends of the transverse pin are engaged in the pin grooves, the transverse pin is in a horizontal position. The transverse pin 4 serves two purposes: firstly, to fix the rectangular steel scissor brace 1, and secondly, to support the work platform ramp.

[0037] Multiple identical rectangular steel scissor braces 1 are set at intervals along the horizontal direction. A work platform plank is erected between the transverse pins 4 of two adjacent rectangular steel scissor braces 1 to facilitate workers' movement and operation.

[0038] like Figure 5 As described above, multiple layers of rectangular steel scissor bracing 1 can be set in the vertical direction. The overall shape of the multiple layers of rectangular steel scissor bracing 1 matches the overall cross-sectional shape of the non-vertical concrete wall reinforcement. In one embodiment, the length of the horizontal pin 4 of the upper layer of rectangular steel scissor bracing 1 is less than the length of the horizontal pin 4 of the lower layer of rectangular steel scissor bracing 1.

[0039] like Figure 6 As shown, multiple rectangular steel scissor braces 1 are installed horizontally and vertically to form a complete rebar tying platform device for non-vertical concrete walls. The rebar tying platform device for non-vertical concrete walls is divided into multiple layers and rows according to the height and length of the reinforced concrete wall. Layers are defined by the height of a single manual rebar tying operation, generally 1.8m, with a maximum of 2.2m. Rows are determined by the length and rigidity of the planks erected on the platform, generally 2-4m.

[0040] like Figure 5 As shown, based on the height of the gate chamber wall, each row of devices is fabricated in three layers to form a complete set. Because the wall surface is not vertical, each layer of the support device in the set has a certain dimensional deviation. Therefore, the device design should strictly follow the shape of the steel reinforcement arrangement to ensure accurate installation.

[0041] The specific dimensions of each layer and row of the device are determined from the drawings. To prevent dimensional deviations that may affect installation, cross-sectional views and detailed drawings of the device are drawn on-site according to the actual dimensions of the wall. The device is then manufactured with the ground dimensions as a reference.

[0042] In one embodiment, the rectangular steel scissor brace is made of rectangular steel with specifications of 30cm*50cm*1.5mm. It is cut according to the actual ground measurement drawing and the cutting line is left to allow for the welding of the steel pipe for the reinforcing bar.

[0043] The locking bolt 2 for the scissor brace uses a capped bolt with a diameter of 2cm and a length of not less than 8cm. First, arrange the two rectangular steel sections into a scissor brace shape according to the actual ground measurement diagram. Drill a hole with a diameter of 2.2cm at the center of the intersection of the scissor brace. Use the locking bolt to lock the rectangular steel through the hole. The two steel rods can rotate freely perpendicular to the bolt.

[0044] The steel pipe 3 for securing the reinforcing bar is made of a steel pipe with an inner diameter of 32mm, a steel plate of 5mm, and bolts with a diameter of 10mm. The prepared steel pipe is welded to the end of the rectangular steel shear brace and kept parallel to the reinforcing bar to be secured.

[0045] The horizontal pin is made of 48mm diameter steel pipe, with hooks made of 5mm thick steel plate welded to both ends, so that the pin can be hung horizontally in the pin slots reserved at both ends of the top surface of the scissor brace to fix the scissor brace and support the work platform plank.

[0046] In one embodiment, depending on the length of the gate chamber wall, if the new platform devices are arranged in rows of 2m, then 5 rows of complete sets of devices are required so that scaffolding can be erected on the same floor to form a complete construction platform for steel reinforcement binding.

[0047] Based on the wall height and length, it is divided into multiple layers and multiple rows. As mentioned above, it is designed based on the gate chamber wall. During installation and use, it needs to be carried out layer by layer from bottom to top. Specifically, the operation method of the non-vertical concrete wall reinforcement binding platform device of the present invention includes the following steps:

[0048] Step 1: Before installing the rectangular steel scissor brace 1, first complete the binding of the first layer of wall reinforcement within the height range of the rectangular steel scissor brace 1 device. This height shall not exceed the maximum installation height of the worker at one time, that is, not more than 2.2m.

[0049] Step 2: After the first layer of wall reinforcement is tied, install multiple rectangular steel scissor braces based on the first layer of wall reinforcement at this height to form the first layer of rectangular steel scissor brace support. First, open the rectangular steel scissor braces, then put the cylindrical parts of the two locking steel pipes at the top of the rectangular steel scissor braces onto the vertical and non-vertical wall reinforcement on both sides respectively. The lower end of the rectangular steel scissor braces should contact the concrete ground and keep the bottom flat. The cylindrical parts of the two locking steel pipes at the bottom of the rectangular steel scissor braces should also be put onto the vertical and non-vertical wall reinforcement on both sides respectively. Then, tighten the bolts of the locking steel pipes to prevent the locking steel pipes from falling off. Finally, engage the horizontal pins into the pin slots at the top of the rectangular steel scissor braces. Install multiple rectangular steel scissor braces in sequence and side by side to form the first layer of rectangular steel scissor brace support.

[0050] Step 3: After the first layer of rectangular steel scissor bracing is installed, steel or wooden planks are erected on it to form a working platform. The second layer of wall reinforcement is tied using the working platform. Reinforcement tying workers can climb onto the working platform using steel ladders to tie the second layer of reinforcement. Semi-finished reinforcement can also be hoisted onto the working platform by a crane so that workers can pick it up and tie it nearby.

[0051] Step 4: After the second layer of wall reinforcement is tied, repeat steps 2 and 3 to complete the erection of the second layer of rectangular steel scissor bracing and the tying of the third layer of wall reinforcement.

[0052] Step 5: After all the rebar tying work is completed, dismantle the work platform and rectangular steel scissor bracing from top to bottom.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
