Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically to a concrete interception device of different grades. Background Technology

[0002] Currently, in high-rise building projects, there are differences in concrete grades between the lower-grade walls / columns and beams / slabs. To prevent lower-grade concrete (beams / slabs) from seeping into higher-grade concrete (walls / columns) and thus avoiding serious quality accidents, projects often use wire mesh or airbags to intercept the concrete of different grades. While these measures solve the concrete interception problem, they have some shortcomings. Using inflatable airbags for interception is difficult because the spacing between the reinforcing bars in the main beams of building projects is small, making it hard to install the airbags properly. Furthermore, workers often have poor control over the inflation volume, resulting in poor sealing effects. Additionally, these airbags are easily damaged and cannot be reused. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a concrete interception device with different grades, which can use a two-layer sealing method of support frame and rubber baffle to reduce the risk of concrete overflow. The rubber baffle is easy to replace and relatively sturdy, reducing the risk of damage due to concrete impact.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete interception device of different grades, comprising a horizontal support rod, both ends of which are slidably connected to a vertical support rod, a plurality of support plates being detachably connected to the horizontal support rod, and baffle plates being detachably connected to the vertical support rod.

[0005] The above structural design allows for a two-layer sealing method using support plates and baffles, reducing the risk of concrete overflow. The rubber baffles are easy to replace and relatively sturdy, reducing the risk of damage from concrete impact.

[0006] Preferably, the upper end of the support piece is inserted into the transverse support rod.

[0007] The above structural design simplifies the connection between the support plate and the horizontal support rod, making it easier to install and position quickly.

[0008] Preferably, the upper end of the support plate is fixedly connected to symmetrically arranged plug rods, and the outer wall of the transverse support rod is provided with a plug groove that matches the plug rod. A positioning bolt passes through the plug rod, and the outer wall of the positioning bolt is in contact with the upper surface of the transverse support rod.

[0009] The above structural design enhances the connection strength between the symmetrical plug rod and the plug groove, preventing the support plate from tilting or falling off. The positioning bolts further lock the position, preventing the support plate from loosening due to concrete impact or vibration during construction, thus improving the overall stability of the device.

[0010] Preferably, the upper end of each vertical support rod is provided with a locking screw, the lower end of each locking screw is fixedly connected with an anti-slip pad, and the lower end of the locking screw abuts against the upper surface of the horizontal support rod.

[0011] With the above structural design, the locking screw can fix the relative positions of the horizontal and vertical support rods by tightening, preventing them from sliding relative to each other during construction; the anti-slip pad increases friction, further enhancing the locking effect, ensuring the stability of the device dimensions, and guaranteeing the accuracy of baseline control.

[0012] Preferably, the baffle is made of a flexible material that can prevent concrete from sticking, and the flexible material is non-stick rubber.

[0013] With the above structural design, the anti-stick properties prevent concrete from sticking to the baffle, and the flexible material can adapt to slight deformations, ensuring a tight fit between the baffle and other components and preventing concrete leakage.

[0014] Preferably, each of the vertical support rods has multiple first threaded holes, and the baffle has through holes corresponding to the first threaded holes.

[0015] The above structural design and threaded connection make the baffle plate and the vertical support rod more securely fixed.

[0016] Preferably, the vertical support rod has a long insertion port that matches the baffle, and a clamping bolt is threaded through the vertical support rod.

[0017] The above structural design allows for flexible adjustment of the baffle length to accommodate steel bars with different spacings; the clamping bolts fix the baffle by compression, making operation simple and reliable, while also facilitating quick disassembly and position adjustment, thus improving construction efficiency.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This device uses a two-layer sealing method of support plates and baffles to reduce the risk of concrete overflow. The rubber baffles are easy to replace and relatively sturdy, reducing the risk of damage due to concrete impact. Within a certain range, this device can be adaptively adjusted according to the spacing between the two sides of the beam reinforcement, so that it can be installed on both sides of the beam reinforcement, improving the applicability of this device.

Detailed Implementation

[0020] Example 1: Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a concrete interception device of different grades, including a horizontal support rod 1, both ends of which are slidably connected to a vertical support rod 2. The sliding connection between the horizontal support rod 1 and the vertical support rod 2 enables flexible adjustment of the device width, which can be adaptively adjusted according to the spacing between the two sides of the beam reinforcement. Multiple support plates 3 are detachably connected to the horizontal support rod 1, and the support plates 3 are equally spaced on the horizontal support rod 1. The number of support plates 3 can be increased or decreased according to the spacing between the two sides of the beam reinforcement. A baffle plate 4 is detachably connected to the vertical support rod 2.

[0021] Each vertical support rod 2 has a locking screw 21 inserted through its upper end. The lower end of each locking screw 21 is fixedly connected to an anti-slip pad, and the lower end of the locking screw 21 abuts against the upper surface of the horizontal support rod 1. Tightening the locking screw 21 secures the relative position of the horizontal support rod 1 and the vertical support rod 2, preventing relative sliding under concrete pouring pressure. The anti-slip pad increases friction, further enhancing the locking effect and ensuring the overall dimensional stability of the device.

[0022] The upper end of the support plate 3 is inserted into the transverse support rod 1. The upper end of the support plate 3 is fixedly connected to symmetrically arranged insertion rods 31. The outer wall of the transverse support rod 1 is provided with an insertion groove 32 that matches the insertion rod 31. A positioning bolt 33 passes through the insertion rod 31. The outer wall of the positioning bolt 33 is in contact with the upper surface of the transverse support rod 1. The positioning bolt 33 is a threaded taper pin with threads only at the tail end.

[0023] Insert the connector 31 axially along the connector groove 32, then pass the positioning bolt 33 through the connector 31, and finally tighten the nut. The symmetrical connector 31 and connector groove 32 enhance the connection strength between the support plate 3 and the transverse support rod 1, preventing the support plate 3 from tilting or falling off; the positioning bolt 33 further locks the position, preventing the support plate 3 from loosening due to construction vibration, ensuring that the support plate 3 forms a continuous interception auxiliary structure, and improving the overall impact resistance of the device.

[0024] The baffle 4 is made of a flexible material that prevents concrete from sticking together. This flexible material is an anti-stick rubber, such as square-shaped butyl rubber. The anti-stick property prevents concrete from adhering to the baffle 4, reducing cleaning work during dismantling and improving turnover efficiency. The flexible material can adapt to minor deformations, ensuring that the baffle 4 fits tightly against the reinforcing steel or other components, effectively blocking concrete overflow while avoiding damage to the reinforcing steel or structure from rigid contact, thus ensuring the sealing of the interception.

[0025] Each of the vertical support rods 2 has multiple first threaded holes 51, and each baffle 4 has a through hole 52 corresponding to the first threaded holes 51. A bolt is inserted into the through hole 52, and then the bolt is installed into the first threaded hole 51. The threaded connection securely fixes the baffle 4 to the vertical support rod 2.

[0026] Working principle: First, the staff adjusts the overall width of the device according to the actual spacing on both sides of the beam reinforcement. Then, the staff determines the number of support plates 3 (arranged at equal intervals). The symmetrical plug-in rods 31 at the upper end of each support plate 3 are aligned with the plug-in slots 32 on the outer wall of the transverse support rod 1, inserted and initially positioned. The positioning bolts 33 (conical pins) are passed through the reserved holes on the plug-in rods 31. Nuts are installed and tightened on the other side of the transverse support rod 1 to ensure that the support plates 3 are vertical and stable, without tilting or loosening. Next, the staff slides the vertical support rods 2 at both ends of the transverse support rod 1 along the transverse support rod 1. Then, the locking screws 21 at the upper end of the vertical support rods 2 are rotated so that the anti-slip pads at the lower end of the vertical support rods 2 are in close contact with the upper surface of the transverse support rod 1. The relative positions of the transverse support rods 1 and the vertical support rods 2 are fixed by tightening the locking screws 21 to prevent the frame from sliding in subsequent operations. Next, installation is required during the rebar binding process. The horizontal support rod 1 and the vertical support rod 2 are fixedly connected to the external support frame. Then, the workers cut the baffle 4 according to the construction needs and drill through holes 52 on the baffle 4. The bolts are passed through the through holes 52 and screwed into the first threaded hole 51. The bolts are tightened one by one, and the baffle 4 is tightly attached to the support plate 3 to form a sealed interception surface.

[0027] Example 2: Please see Figure 4 Compared with Embodiment 1, Embodiment 2 is an improvement. A long insertion port 61 matching the baffle 4 is provided on the vertical support rod 2, and a clamping bolt 62 is threaded through the vertical support rod 2. The end of the baffle 4 is inserted into the long insertion port 61, and the clamping bolt 62 quickly fixes the baffle 4 by compression. This method is simple to operate and provides reliable fixation, facilitating rapid adjustment of the baffle 4's position in confined spaces, thus improving construction efficiency and interception accuracy. For other parts, please refer to Embodiment 1.

[0028] Working principle: First, the staff adjusts the overall width of the device according to the actual spacing on both sides of the beam reinforcement. Then, the staff determines the number of support plates 3 (arranged at equal intervals). The symmetrical plug-in rods 31 at the upper end of each support plate 3 are aligned with the plug-in slots 32 on the outer wall of the transverse support rod 1, inserted and initially positioned. The positioning bolts 33 (conical pins) are passed through the reserved holes on the plug-in rods 31. Nuts are installed and tightened on the other side of the transverse support rod 1 to ensure that the support plates 3 are vertical and stable, without tilting or loosening. Next, the staff slides the vertical support rods 2 at both ends of the transverse support rod 1 along the transverse support rod 1. Then, the locking screws 21 at the upper end of the vertical support rods 2 are rotated so that the anti-slip pads at the lower end of the vertical support rods 2 are in close contact with the upper surface of the transverse support rod 1. The relative positions of the transverse support rods 1 and the vertical support rods 2 are fixed by tightening the locking screws 21 to prevent the frame from sliding in subsequent operations. Next, during the rebar tying process, the horizontal support rod 1 and the vertical support rod 2 are fixedly connected to the external support frame. Then, the workers insert the end of the baffle 4 into the long socket 61 and tighten the bolt 62 to quickly fix the baffle 4 by squeezing. The operation is simple and the fixation is reliable. It is easy to quickly adjust the position of the baffle 4 in a narrow space. The baffle 4 is close to the support plate 3 to form a sealed interception surface.
