Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a barrier device for pouring high-grade concrete at the junction of beams and columns. Background Art

[0002] Columns and walls in cast-in-place concrete frame structures usually need to bear greater loads, so higher-grade concrete is required to meet their bearing capacity and stiffness requirements. The loads on beams and slabs are relatively small, so lower-grade concrete can be used. During the pouring process, columns and walls are usually poured first, and then beams and slabs. When pouring beams and columns, the existing concrete airbags have a high height. During pouring, the high-grade concrete and the low-grade concrete share the same steel frame, so the concrete formwork cavity is connected. When pouring high-grade concrete, a temporary barrier device needs to be set at the junction to prevent high-strength concrete from flowing into low-strength areas, avoid excessive use of high-grade concrete, and reduce overall construction costs.

[0003] For example, the patent with announcement number CN219298800U discloses a barrier for pouring concrete of different types at beam-column joints. The barrier includes a square tube crossbeam, under which a long slot is installed to connect the barrier teeth, and the airbag assembly is installed on the outer sleeve of the teeth. After installation, the gap is inflated to improve the concrete barrier effect. However, when pouring beams and columns, the existing concrete airbags are prone to serious deformation due to a certain height. During the pouring process, the airbags cannot withstand the pressure of concrete, resulting in deformation and collapse of the overall structure, which leads to leakage and inconvenience in use.

When the T-block 4 is inserted and pulled out in the vertical hole formed by the L-shaped groove 3 after the first plug plate 1 and the second plug plate 2 are aligned and spliced, the T-block 4 is used to squeeze and roll the rubber roller 711, thereby driving the worm gear ring 714 to push the worm 72 to rotate, and then the cooperation of the worm 72, the bevel gear set 73 and the adjusting screw 74 is used to push the clamping block 75 to move left and right in the through-hole on the middle plate of the positioning groove 5 and the installation cavity 7, so as to realize the clamping, locking, control and unlocking of the steel bars at the bottom of the crossbeam steel cage in the positioning groove 5 by the clamping block 75.

[0035] Specifically, the first plug plate 1 and the second plug plate 2 are sequentially placed in the cross beam reinforcement cage, so that the first plug plate 1 and the second plug plate 2 are upright and the positioning grooves 5 at the upper and lower ends of the outer sides engage the four corners of the cross beam reinforcement cage, and after the four corners of the cross beam reinforcement cage are engaged in the middle of the U-shaped airbag 6 in the positioning groove 5, the U-shaped plate 52 is deflected to engage the convex groove 51, and the positioning bolt 53 is tightened to insert it into the positioning hole 54 on the U-shaped plate 52, so that the opening of the U-shaped groove on the U-shaped plate 52 and the opening of the positioning groove 5 are misaligned to lock the four corners of the cross beam reinforcement cage, and the four corners of the cross beam reinforcement cage squeeze the U The airbag 6 is deformed to fill the gap between the steel bar and the U-shaped plate 52 and the inner wall of the beam casting template, and the sealing of the first plug plate 1 and the second plug plate 2 with the inner wall of the beam casting template is strengthened, so that the first plug plate 1 and the second plug plate 2 are aligned and stand at the intersection of the beam and column casting, and the first plug plate 1 and the second plug plate 2 are attached to the inner wall of the casting template outside the steel cage to form a barrier, and the T-block 4 is inserted into the vertical hole formed by the L-shaped groove 3 after the first plug plate 1 and the second plug plate 2 are aligned and spliced. When the T-block 4 moves down, it squeezes the adjusting wheel 71 in the L-shaped groove 3 to slightly deform, and drives the adjusting wheel 71 to move When the adjusting wheel 71 rotates, the worm 72 is driven to rotate. When the worm 72 rotates, the bevel gear set 73 drives the adjusting screw 74 to rotate, thereby pushing the clamping block 75 at the end of the adjusting screw 74 to move in the through opening on the positioning groove 5 and the middle plate of the installation cavity 7, so that the clamping block 75 extends into the positioning groove 5 to clamp the bottom steel bar of the crossbeam steel cage inside it, thereby cooperating with the lock buckle of the U-shaped plate 52 to fix the first plug plate 1 and the second plug plate 2, and after the T-shaped block 4 is fully inserted into the L-shaped groove 3, the splicing end of the first plug plate 1 and the second plug plate 2 is restricted and positioned, so that the first plug plate 1 and the second plug plate 2 are realized. The automatic locking of the bottom steel bars of the beam reinforcement cage by the plate 1 and the second plug plate 2 ensures the stability of the first plug plate 1 and the second plug plate 2 in fitting with the inner wall of the template at the intersection of the beam for partition, and avoids the problem of leakage caused by the deformation and collapse of the overall structure of the traditional concrete airbag due to the gravity impact of high-grade concrete when pouring the supporting column of the house. After the concrete of the column is initially solidified, the clamping block 75 moves in the opposite direction to contact the clamping of the steel bars, and the positioning bolts 53 are unscrewed to remove the first plug plate 1 and the second plug plate 2 from the four corner steel bars of the beam reinforcement cage, which is easy to operate.

[0036] like Figure 2-Figure 7 As shown, in order to realize the rapid inflation and deflation operation of the multiple U-shaped airbags 6 on the first plugboard 1 and the second plugboard 2, this embodiment provides the following technical solutions:

[0037] A piston cylinder 76 is fixedly connected between the inner walls at the middle of the installation chamber 7, a piston rod 761 is movably sleeved in the piston cylinder 76, the top of the piston rod 761 extends through the first plugboard 1 and the outside of the top of the second plugboard 2, a fixing plate 762 is fixedly connected to the outer wall of the piston rod 761 in the installation chamber 7, a return spring 763 is fixedly connected between the lower end of the top plate of the installation chamber 7 and the top of the fixing plate 762, a connected air supply pipe 764 is fixedly connected to the side wall at the bottom of the piston cylinder 76, a three-way pipe 765 is fixedly connected to the end of the air supply pipe 764, and a one-way air outlet pipe 767 is fixedly connected to the ends of the other two ends of the three-way pipe 765, respectively, and the one-way air supply pipe 766 and the one-way air outlet pipe 767 at the upper and lower ends of the three-way pipe 765 are respectively connected to the U-shaped airbag 6.

[0038] The tops of the first plug plate 1 and the second plug plate 2 on one side of the piston rod 761 are rotatably connected to the movable rod 10 respectively. A pressure plate 11 is fixedly connected to the outer wall of the movable rod 10. The movable rod 10 is fixedly connected to the edge of one side of the pressure plate 11.

[0039] Specifically, after the first plug plate 1 and the second plug plate 2 are spliced ​​and fixed with the bottom steel bars of the cross beam steel cage, the piston rod 761 on the top of the first plug plate 1 and the second plug plate 2 is pressed downward, the piston rod 761 moves downward and contracts in the piston cylinder 76 and stretches the return spring 763, and the piston rod 761 squeezes the compressed gas stored in the piston cylinder 76 downward, so that it enters the three-way pipe 765 through the air supply pipe 764, and then enters the U-shaped airbags 6 in the upper and lower positioning grooves 5 of the first plug plate 1 and the second plug plate 2 through the one-way air intake pipe 766 at the upper and lower ends of the three-way pipe 765, respectively, so that the multiple U-shaped airbags 6 on the first plug plate 1 and the second plug plate 2 are inflated synchronously, so that after the expansion, the four corner steel bars of the cross beam steel cage engaged in the positioning groove 5 are fully wrapped, and the risks between the U-shaped plate 52 and the steel bars and the inner wall of the casting template are further compressed and filled, so as to strengthen the first plug plate 1 The sealing of the internal groove of the casting template with the second plug plate 2 prevents the waste caused by the high-grade concrete leaking into the beam casting space from the gap between the positioning groove 5 and the inner wall of the casting template when casting the house support column. After the top of the piston rod 761 is flush with the top of the first plug plate 1 and the second plug plate 2, the pressure plate 11 is rotated based on the movable rod 10, and the pressure plate 11 is rotated to the top of the piston rod 761 and then restricted to ensure the normal operation of the U-shaped air bag 6 during casting. After the concrete of the column is initially solidified, the pressure plate 11 is rotated to one side of the piston rod 761. The piston rod 761 automatically moves up and resets under the action of the reset spring 763. The piston rod 761 uses the cooperation of the air supply pipe 764, the three-way pipe 765 and the one-way air outlet pipe 767 to automatically extract the gas in each U-shaped air bag 6, so that it is restored to facilitate the removal of the first plug plate 1 and the second plug plate 2, which is convenient and quick.

[0040] In order to realize the rapid alignment and splicing of the first plugboard 1 and the second plugboard 2, as shown in FIG. Figure 3 and Figure 8-Figure 10 As shown, this embodiment provides the following technical solutions:

[0042] The adjusting rod 96 includes an intermediate sleeve 961 and a driving screw rod 962 which are respectively threadedly sleeved on both ends of the intermediate sleeve 961. The ends of the driving screw rod 962 are fixedly connected with a clamping block 963.

[0043] Specifically, the first plug plate 1 and the second plug plate 2 are placed in the crossbeam steel cage at the intersection of the crossbeams, and after the U-shaped plate 52 is locked to the steel bars at the bottom of the crossbeam steel cage, the first plug plate 1 and the second plug plate 2 are pushed to move slightly on the steel bars of the crossbeam steel cage in turn, so that the J-shaped hooks 93 on the side walls of the first bracket 91 and the second bracket 92 are respectively attached to the side walls of the first plug plate 1 and the second plug plate 2, that is, the splicing and calibration of the first plug plate 1 and the second plug plate 2 are automatically completed, and the horizontal parallel straightness of the first plug plate 1 and the second plug plate 2 is ensured, so as to ensure the smooth sliding of the T-block 4 in the L-shaped groove 3 after the first plug plate 1 and the second plug plate 2 are aligned. After the calibration of the first plug plate 1 and the second plug plate 2 is completed, the ends of the intermediate sleeve 961 are The card blocks 963 are respectively movably engaged in the card grooves 95 on the side walls of the first bracket 91 and the second bracket 92, and the intermediate sleeve 961 is rotated. The intermediate sleeve 961 rotates along the outer wall of the driving screw 962 based on the thread on the inner wall, so that the driving screw 962 cooperates with the card blocks 963 to push the first bracket 91 and the second bracket 92 to move in the opposite direction in the mounting grooves 8 on the first plug plate 1 and the second plug plate 2. After the distance between the first bracket 91 and the second bracket 92 becomes larger, the ends of the J-shaped hooks 93 on each other's side walls are pulled to respectively buckle the positioning columns 94 on the side walls of the first plug plate 1 and the second plug plate 2, thereby realizing the auxiliary locking of the spliced ​​contact ends of the first plug plate 1 and the second plug plate 2, further enhancing its stability of isolation in the beam calibration template, which is convenient and practical.
