Description

Technical Field

[0001] This utility model belongs to the field of building wall casting, and specifically relates to a tool for separating and blocking high and low grade concrete in shear walls. Background Technology

[0002] In some locations, there are horizontal divisions between high and low concrete grades in shear walls, or the concrete grades between the wall ties and the concrete wall are inconsistent. The two grades of concrete need to be poured separately, but the connection between them should be tight without cold joints. That is, when the division is clear, if the concrete grades differ by more than two, it is necessary to stop the flow. If the low grade concrete flows into the high grade concrete, it will cause insufficient strength, and if the high grade concrete flows into the low grade concrete, it will cause cost waste.

[0003] The common practice is to use wire mesh as a barrier. However, during the pouring process, the wire mesh is easily damaged due to its low rigidity, resulting in an unsatisfactory barrier effect. Utility Model Content

[0004] This utility model provides a tool for separating and blocking concrete of different grades in shear walls, in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shear wall high and low grade concrete separation and retaining tool, installed between casting templates, includes a retaining panel and retaining flanges. The retaining panel is set perpendicular to the casting template, and the retaining flanges are set on both horizontal sides of the retaining panel. The casting templates on both sides are fixed by tie rods. The ends of the retaining flanges are attached to the tie rods. Horizontal and vertical steel bars are set between the casting templates, and two vertical retaining steel bars are fixed on the horizontal steel bars. A retaining tie bar parallel to the retaining panel is connected between the two vertical retaining steel bars. The two ends of the retaining tie bar are hooked on the vertical retaining steel bars and retain the retaining flanges. The tie rod is attached to the side of the stubble panel away from the stubble edge. Different grades of concrete are poured on both sides of the stubble panel. The stubble panel and the stubble edge are assembled and connected in the height direction, including the end plate, the standard plate and the first section plate. The first section plate is located at the bottom, the end plate is located at the top and extends upward from between the casting templates. The standard plate is set with several sections and is connected in sequence and installed between the first section plate and the end plate. The end plate, the standard plate and the first section plate are connected by hinge plate one, hinge plate two and hinge pin. Hinges plate one and hinge plate two are respectively fixed on adjacent sections of the stubble panel. Both hinge plates one and hinge plate two have connecting bushings and are connected by hinge pins.

[0006] By adopting the above technical solution, the stubble-blocking folded edge of this tool can not only serve as a positioning and fixation mechanism, but also ensure that the tool is stably supported vertically in sequence. It has high overall rigidity and is not easily damaged. During the pouring process, both sides are vibrated to ensure compaction without cold joints. This prevents low-grade concrete from flowing into the high-grade side and high-grade concrete from flowing into the low-grade side, thus avoiding insufficient concrete strength and wasted costs. Furthermore, the height direction is assembled from the end plate, standard plate, and first section plate, making construction convenient and simple, facilitating the turnover and transportation of parts, and resulting in high construction efficiency.

[0007] Preferably, the top of the first section plate, the bottom of the end plate, and the two ends of the standard plate have 45° bevels at the stubble edges.

[0008] By adopting the above technical solution, this stubble-blocking tool interlocks with oblique openings, thus maintaining high structural strength while being detachable and reassembled, and stably completing the stubble-blocking work.

[0009] Preferably, the part of the end plate that extends out of the casting template has two upward auxiliary operation holes.

[0010] By adopting the above technical solution, the stubble-blocking tool can be removed using the lifting auxiliary operation hole after pouring, and can be reused.

[0011] Preferably, a vibration motor is also installed at the part of the end plate that extends out of the casting template.

[0012] By adopting the above technical solution, the vibration motor can be started when the stubble-blocking tool needs to be removed after the concrete is poured, and the stubble-blocking tool can be easily removed after the concrete is vibrated.

[0013] Preferably, the width of the retaining panel is the distance between the two casting templates minus the thickness of the inner and outer protective layers minus the diameter of the inner and outer vertical reinforcing bars minus the diameter of the inner and outer horizontal reinforcing bars.

[0014] By adopting the above technical solution, the width of the stubble-blocking device is reasonable, which not only does not affect the protective layer, but also maximizes the separation of concrete of different grades.

[0015] Preferably, a water-stop steel plate groove is opened at the bottom center of the first section plate.

[0016] By adopting the above technical solution, a waterstop steel plate can be inserted without affecting the construction of the waterstop steel plate.

[0017] Preferably, there are two hinge plates, one hinge plate and two hinge pins in the width direction of the stop panel.

[0018] By adopting the above technical solution, the assembled structure has high strength.

[0019] Preferably, the stubble panel and stubble edge are made of 3mm thick steel plate, the stubble edge is 50mm long, the end plate and standard plate are 500mm high, and the first section plate is 800mm high.

[0020] By adopting the above technical solution, the dimensions are reasonable, the strength is sufficient, and the construction is convenient.

[0021] The beneficial effects of this utility model are as follows: the stubble-stopping tool's folded edge not only provides positioning and fixation but also ensures the tool is stably supported vertically, resulting in high overall rigidity and resistance to damage. During pouring, both sides are vibrated to ensure compaction without cold joints, preventing low-grade concrete from flowing into the high-grade side and vice versa. This avoids insufficient concrete strength and wasted costs. Furthermore, the height is achieved by assembling the end plate, standard plate, and first section plate, making construction convenient and simple, facilitating component turnover and transportation, and resulting in high construction efficiency.

[0022] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of this invention may be realized and obtained by means of the methods particularly pointed out in the description.

The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0030] Combination Figure 1-5 A shear wall high-low grade concrete separation and retaining tool is installed between casting templates 1. It includes a retaining panel 2 and retaining flanges 3. The retaining panel 2 is perpendicular to the casting template 1. The retaining flanges 3 are located on both horizontal sides of the retaining panel 2. The casting templates 1 on both sides are fixed by tie rods 4. The ends of the retaining flanges 3 are attached to the tie rods 4. Horizontal steel bars 5 and vertical steel bars 6 are provided between the casting templates 1, and two vertical retaining steel bars 7 are fixed on the horizontal steel bars 5. A retaining tie bar 8 parallel to the retaining panel 2 connects the two vertical retaining steel bars 7. The two ends of the retaining tie bar 8 are hooked onto the vertical retaining steel bars 7, and the retaining tie bar 8 is attached to the side of the retaining panel 2 away from the retaining flanges 3. Different grades of concrete are poured on both sides of the stubble panel 2. The stubble panel 2 and the stubble fold 3 are assembled and connected in the height direction, including the end plate 9, the standard plate 10 and the first section plate 11. The first section plate 11 is located at the bottom, the end plate 9 is located at the top and extends upward from between the pouring templates 1. The standard plate 10 is provided with several sections and is installed between the first section plate 11 and the end plate 9 after being connected in sequence. The end plate 9, the standard plate 10 and the first section plate 11 are connected by hinge plate 1 21, hinge plate 22 and hinge pin 23. Hinges plate 1 21 and hinge plate 22 are respectively fixed on adjacent sections of the stubble panel 2. Both hinge plates 1 21 and hinge plate 22 have connecting bushings and are connected by hinge pin 23.

[0031] The stubble-blocking folded edge of this tool not only serves for positioning and fixation but also ensures that the tool is stably supported vertically. It has high overall rigidity and is not easily damaged. During the pouring process, both sides are vibrated to ensure compaction without cold joints. This prevents low-grade concrete from flowing into the high-grade side and vice versa, thus avoiding insufficient concrete strength and wasted costs. Furthermore, the tool is assembled from the end plate 9, standard plate 10, and first section plate 11 in the height direction, making construction convenient and simple. The parts are easy to transport and relocate, resulting in high construction efficiency.

[0032] The top of the first section plate 11, the bottom of the end plate 9, and the two ends of the standard plate 10 each have a 45° bevel 12. This stubble-stopping tool interlocks with each other through the bevels, thus maintaining high structural strength and stably completing the stubble-stopping work while being detachable and reassembled.

[0033] Two lifting auxiliary operation holes 13 are provided at the part of the end plate 9 that extends out of the casting template 1. After casting, the stubble-blocking tool can be taken out using the lifting auxiliary operation holes 13 and reused.

[0034] A vibration motor 14 is also installed at the part of the end plate 9 that extends out of the casting template 1. When the stubble-blocking tool needs to be removed after the casting is completed, the vibration motor 14 can be started, and the stubble-blocking tool can be easily removed after the concrete is vibrated.

[0035] The width of the retaining panel 2 is the distance between the two casting templates 1 minus the thickness of the inner and outer protective layers, minus the diameter of the inner and outer vertical reinforcing bars 6, and minus the diameter of the inner and outer horizontal reinforcing bars 5. The width of the retaining device is reasonable, which neither affects the protective layer nor fails to maximize the separation of concrete of different grades.

[0036] The bottom center of the first section plate 11 has a groove 15 for a water-stop steel plate, which can be inserted into the water-stop steel plate without affecting the construction of the water-stop steel plate.

[0037] Two hinge plates 21, 22 and 23 are provided in the width direction of the retaining panel 2, resulting in high assembly strength.

[0038] The stubble panel 2 and the stubble fold 3 are made of 3mm thick steel plates. The stubble fold 350mm long, the end plate 9 and the standard plate 10 are 500mm high, and the first section plate 11 is 800mm high. The dimensions are reasonable, the strength is sufficient, and the construction is convenient.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
