Description

Technical Field

[0001] This invention belongs to the field of building intelligent equipment technology, specifically relating to a concrete partition device for beam-column joint construction. Background Technology

[0002] In building construction, beams and columns intersect, and since the concrete strength requirements for beams and columns are different, they need to be poured separately. When pouring the columns, partitions need to be installed at a certain distance on both sides of the column to prevent concrete from scattering during pouring.

[0003] Because the reinforcing cage of the beam is a rectangular frame made of tied reinforcing bars, setting up partitions inside the beam requires considering the need to pass through the densely packed reinforcing bars to enter the interior of the beam's reinforcing cage, making conventional formwork unsuitable. Currently, there are several types of beam-column casting partitions, including tightly bound mesh partitions and inflatable partitions. Tightly bound mesh partitions involve binding a mesh inside the reinforcing cage. However, the mesh cannot completely block the concrete, and some concrete still flows to the outside. Furthermore, the mesh can crack under the pressure of the concrete, causing a large amount of concrete to spill out. After the concrete is poured, the mesh itself has low strength and cannot be removed. Inflatable partitions use multiple balloon-like containers, which are inflated to fill the reinforcing cage of the beam, thus creating a partition around the concrete. However, with this method, the inflated containers are prone to exploding, causing a large amount of concrete to spill out, rendering the partition ineffective. The inflatable material of inflatable partitions is mostly rubber. After the concrete is poured, the rubber material adheres to the concrete and cannot be disassembled and reused. Neither of the above two types of partitions can be recycled and reused, so they are consumables, which increases construction costs. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete partition device for beam-column joint construction, so as to solve the technical problem that the concrete at the beam-column joint cannot be properly partitioned during concrete pouring in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A concrete partition device for beam-column joint construction includes a base for placement at the concrete partition location of the beam-column joint, a left sliding component and a right sliding component that slide along the left-right direction of the base, an upper sliding component and a lower sliding component that slide along the up-down direction of the base, and a driving component for driving the left sliding component, right sliding component, upper sliding component, and lower sliding component to slide. The left sliding component includes a left square structure located in the middle and left triangular structures located above and below the left square structure. The left triangular structures slide synchronously with the left square structure to supplement the left square structure into a left trapezoidal structure. The right sliding component has the same structure as the left sliding component and is symmetrically arranged. The upper sliding component includes an upper square structure located in the middle and upper triangular structures located to the left and right of the upper square structure. The upper triangular structures slide synchronously with the upper square structure to supplement the upper square structure into an upper trapezoidal structure. The lower sliding component has the same structure as the upper sliding component and is symmetrically arranged. The left sliding component, right sliding component, upper sliding component, and lower sliding component cooperate to slide and form a square plate identical to the concrete poured at the beam-column joint partition.

[0007] Furthermore, the base includes a first mounting plate, a second mounting plate, and a third mounting plate connected in parallel in the front-rear direction; a left sliding component and a right sliding component are installed between the first mounting plate and the second mounting plate; an upper sliding component and a lower sliding component are installed between the second mounting plate and the third mounting plate; and a driving component is installed on the front side of the third mounting plate.

[0008] Furthermore, the second mounting plate has a left sliding groove on the side near the left sliding component for the left triangular structure to slide back and forth along the hypotenuse. The left triangular structure has a left sliding bar corresponding to the left sliding groove. The left square structure has a left limiting rod extending in the vertical direction. The left triangular structure has a left limiting sleeve that slides up and down along the left limiting rod. The position of the left limiting sleeve on the left triangular structure corresponds to the position of the left limiting rod on the left square structure. When the left square structure moves left and right, the left limiting sleeve moves left and right with the left limiting rod, and thus the left triangular structure moves left and right. Under the limiting conditions of the left sliding groove and the left sliding bar, the left triangular structure can only move along the hypotenuse when moving left and right, thus completing the left square structure into a left trapezoidal structure. The cooperation structure between the right sliding component and the second mounting plate is the same as that between the left sliding component and the second mounting plate.

[0009] Furthermore, the first mounting plate is provided with a left limiting groove for limiting the left square structure to slide in the left and right directions, and the left square structure is provided with a left limiting block corresponding to the left limiting groove; the mating structure between the right square structure and the first mounting plate is the same as the mating structure between the left square structure and the first mounting plate.

[0010] Furthermore, the second mounting plate has an upper sliding groove on the side near the upper sliding component for the upper triangular structure to slide back and forth along the hypotenuse. The upper triangular structure has an upper sliding bar corresponding to the upper sliding groove. The upper square structure has an upper limit rod extending in the left-right direction. The upper triangular structure has an upper limit sleeve that slides left and right along the upper limit rod. The position of the upper limit sleeve on the upper triangular structure corresponds to the position of the upper limit rod on the upper square structure. When the upper square structure moves up and down, the upper limit sleeve moves up and down with the upper limit rod, thereby moving the upper triangular structure up and down. Under the limiting conditions of the upper sliding groove and the upper sliding bar, the upper triangular structure can only move along the hypotenuse when moving up and down, thus supplementing the upper square structure into an upper trapezoidal structure. The mating structure of the lower sliding component and the second mounting plate is the same as the mating structure of the upper sliding component and the second mounting plate.

[0011] Furthermore, the third mounting plate is provided with an upper limit groove for limiting the upper square structure to slide in the vertical direction, and the upper square structure is provided with an upper limit block corresponding to the upper limit groove; the mating structure between the lower square structure and the third mounting plate is the same as the mating structure between the upper square structure and the third mounting plate.

[0012] Furthermore, the driving component is detachably connected to the third mounting plate, and the driving component includes four electric push rods: a left electric push rod, a right electric push rod, an upper electric push rod, and a lower electric push rod, which are respectively detachably connected to the left sliding component, the right sliding component, the upper sliding component, and the lower sliding component.

[0013] Furthermore, the free end of the left electric push rod is detachably connected to the left square structure by bolts, and the connection structure between the right sliding component and the right electric push rod is the same as the connection structure between the left sliding component and the left electric push rod; the free end of the upper electric push rod is detachably connected to the upper square structure by bolts; and the connection structure between the lower sliding component and the lower electric push rod is the same as the connection structure between the upper sliding component and the upper electric push rod.

[0014] Furthermore, the outer periphery of the left sliding component, right sliding component, upper sliding component, and lower sliding component are all separately covered with elastic rubber to avoid the reinforcing bars.

[0015] Furthermore, the drive component is equipped with a retractable hook for hanging the drive component on the top reinforcing bars of the reinforcing cage of the cast beam. The base is in a suspended state during use, which facilitates the outward sliding of the left sliding component, right sliding component, upper sliding component, and lower sliding component.

[0016] The beneficial effects of this invention are:

[0017] The concrete partition device for beam-column joint construction of this invention, formed by the sliding of left, right, upper, and lower sliding components into a trapezoid, allows the entire base to expand and contract into a complete rectangular plate structure, completely isolating the concrete. This rectangular plate structure prevents concrete leakage, has high strength, is not prone to breakage, and can be recycled and reused after use, reducing construction costs. A retractable hook is used to hang the base on top of the reinforcing cage of the beam to be poured, suspending the base in the air. By controlling the left, right, upper, and lower electric push rods, the left, right, upper, and lower electric push rods push the left, right, upper, and lower square plates outwards, simultaneously moving the left, right, upper, and lower triangular plates to form a complete square. The elastic rubber is compressed when it touches the reinforcing steel, and extends outwards where it is not in contact with the steel, cooperating with the formwork outside the reinforcing cage of the beam to form a sealed structure, preventing concrete leakage. After pouring, by controlling the left, right, upper, and lower electric push rods, the left, right, upper, and lower square plates are pushed inward to slide, while simultaneously moving the left, right, upper, and lower triangular plates. After retraction, the base can be removed for reuse, reducing production costs. After pouring, the drive components can be removed before the concrete has completely hardened, improving the turnover rate of the drive components. Attached Figure Description

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] Example 1

[0031] The concrete partition device for beam-column joint construction in this embodiment includes a base 100 for placement at the concrete partition location of the beam-column joint, a left sliding component 200 and a right sliding component 300 that slide along the left-right direction of the base 100, an upper sliding component 400 and a lower sliding component 500 that slide along the up-down direction of the base, and a driving component 600 for driving the left, right, upper, and lower sliding components to slide. The left, right, upper, and lower sliding components cooperate to form a square plate that is identical to the concrete poured at the beam-column joint partition. The base 100 includes a first mounting plate 110, a second mounting plate 120, and a third mounting plate 130 connected in parallel in the front-back direction. The middle parts of the first, second, and third mounting plates are fixedly connected by a central shaft seat 140. The left and right sliding components are installed between the first and second mounting plates. The upper and lower sliding components are installed between the second and third mounting plates, and the driving component is installed on the front side of the third mounting plate.

[0032] The left sliding component 200 includes a left square structure 210 located in the middle and left triangular structures 220 located above and below the left square structure. The left triangular structure slides synchronously with the left square structure so that the left triangular structure completes the left square structure into a left trapezoidal structure. The left square structure is a left square plate, and the left triangular structure is a left triangular plate. Both the left square plate and the left triangular plate are steel plates.

[0033] The second mounting plate 120 has a left sliding groove 121 on the side near the left sliding component, which allows the left triangular structure 210 to slide back and forth along its hypotenuse. A left sliding strip 221 corresponding to the left sliding groove 121 protrudes from the left triangular structure 220 and is welded to the left square plate. A left limiting rod 211 extending vertically is provided on the left square structure 210. The upper and lower ends of the left limiting rod 211 are supported by two left limiting seats 212, keeping the left limiting rod suspended relative to the left square plate. The left limiting seats are welded to the left square plate, and the left limiting rod is fixed to the left limiting seats with bolts. A left limiting sleeve 222 that slides vertically along the left limiting rod is welded to the left triangular structure 220, i.e., the left limiting sleeve 222 is fitted onto the left limiting rod 211. The position of the left limiting sleeve on the left triangular structure corresponds to the position of the left limiting rod on the left square structure, so that the left triangular plate and the left square plate form a trapezoid. When the left square structure moves left and right, the left limiting sleeve moves left and right along with the left limiting rod, and then the left triangular structure moves left and right. Under the limiting conditions of the left sliding groove and the left sliding bar, the left triangular structure can only move along the hypotenuse when moving left and right, thus completing the left square structure into a left trapezoidal structure. The first mounting plate 110 is provided with a left limiting groove 111 for limiting the left square structure 210 to slide in the left and right directions, and a left limiting block 213 corresponding to the left limiting groove is welded onto the left square structure 210.

[0034] The right sliding component 300 includes a right square structure 310 located in the middle and right triangular structures 320 located above and below the right square structure. The right triangular structure 310 slides synchronously with the right square structure so that the right triangular structure completes the right square structure into a right trapezoidal structure. The right square structure is a right square plate, and the right triangular structure is a right triangular plate. Both the right square plate and the right triangular plate are steel plates.

[0035] The structure of the right sliding component is the same as that of the left sliding component and they are symmetrically arranged. The mating structure between the right sliding component and the second mounting plate is the same as that between the left sliding component and the second mounting plate. The mating structure between the right square structure and the first mounting plate is the same as that between the left square structure and the first mounting plate. The specific structure is as follows: A right sliding groove 122 is provided on the side of the second mounting plate 120 near the right sliding component, which allows the right triangular structure 320 to slide back and forth along the hypotenuse. A right sliding strip 321 corresponding to the right sliding groove 122 is protruding on the right triangular structure 320, and the right sliding strip is welded to the right square plate. A right limiting rod 311 extending in the vertical direction is provided on the right square 310. The upper and lower ends of the right limiting rod are supported by two right limiting seats 312, so that the right limiting rod is suspended relative to the right square plate. The right limiting seats are welded to the right square plate, and the right limiting rod is fixed to the right limiting seats by bolts. A right limiting sleeve 322, which slides up and down along the right limiting rod, is welded onto the right triangular structure 321. The right limiting sleeve is fitted onto the right limiting rod. The position of the right limiting sleeve on the right triangular structure corresponds to the position of the right limiting rod on the right square structure. When the right square structure moves left and right, the right limiting sleeve moves left and right along with the right limiting rod, thereby causing the right triangular structure to move left and right. Under the limiting conditions of the right sliding groove and the right sliding bar, the right triangular structure can only move along its hypotenuse when moving left and right, thus completing the right square structure into a right trapezoidal structure. The first mounting plate 110 is provided with a right limiting groove 112 for limiting the right square structure to slide in the left and right directions. A right limiting block 313 corresponding to the right limiting groove is welded onto the right square structure 310.

[0036] The upper sliding component 400 includes an upper square structure 410 located in the center and upper triangular structures 420 located to the left and right of the upper square structure. The upper triangular structures slide synchronously with the upper square structure so that the upper triangular structures supplement the upper square structure into an upper trapezoidal structure. The upper square structure is an upper square plate, and the upper triangular structure is an upper triangular plate. Both the upper square plate and the upper triangular plate are steel plates.

[0037] The second mounting plate 120 has an upper sliding groove 123 on the side near the upper sliding component, which allows the upper triangular structure to slide back and forth along the hypotenuse. An upper sliding strip 421 corresponding to the upper sliding groove protrudes from the upper triangular structure 420 and is welded to the upper triangular plate. An upper limit rod 411 extending in the left-right direction is provided on the upper square structure 410. The left and right ends of the upper limit rod are supported by two upper limit seats 412, keeping the upper limit rod suspended relative to the upper square plate. The upper limit seats are welded to the upper square plate, and the upper limit rod is fixed to the upper limit seats with bolts. An upper limit sleeve 422 that slides left and right along the upper limit rod is welded to the upper triangular structure 420. The position of the upper limit sleeve on the upper triangular structure corresponds to the position of the upper limit rod on the upper square structure. When the upper square structure moves up and down, the upper limit sleeve moves up and down with the upper limit rod, thereby causing the upper triangular structure to move up and down. Under the limiting conditions of the upper sliding groove and the upper sliding strip, the upper triangular structure can only move along the hypotenuse when moving up and down, thus supplementing the upper square structure into an upper trapezoidal structure. The third mounting plate 130 is provided with an upper limit groove 131 for limiting the upper square structure to slide in the vertical direction, and an upper limit block 413 corresponding to the upper limit groove is welded on the upper square structure 410.

[0038] The structure of the lower sliding component 500 is the same as that of the upper sliding component and is symmetrically arranged. The mating structure between the lower sliding component and the second mounting plate is the same as that between the upper sliding component and the second mounting plate. The mating structure between the lower square structure and the third mounting plate is the same as that between the upper square structure and the third mounting plate. The specific structure is as follows: The lower sliding component 500 includes a lower square structure 510 located in the middle and lower triangular structures 520 located to the left and right of the lower square structure. The lower triangular structures slide synchronously with the lower square structure so that the lower triangular structure completes the lower square structure into a lower trapezoidal structure. The lower square structure is a lower square plate, and the lower triangular structure is a lower triangular plate. The lower square plate and the lower triangular plate are steel plates. The side of the second mounting plate 120 near the lower sliding component is provided with a downward groove 124 for the lower triangular structure to slide back and forth along the hypotenuse. The lower triangular structure 520 is provided with a downward strip 521 corresponding to the downward groove, and the downward strip 521 is welded to the lower triangular plate. The lower square structure 510 is provided with a lower limit rod 511 extending in the left-right direction. The left and right ends of the lower limit rod are supported by two lower limit seats 512, so that the lower limit rod is suspended relative to the lower square plate. The lower limit seats are welded to the lower square plate, and the lower limit rod is fixed to the lower limit seats by bolts. The lower triangular structure 520 is provided with a lower limit sleeve 522 that slides left and right along the lower limit rod. The position of the lower limit sleeve on the lower triangular structure corresponds to the position of the lower limit rod on the lower square structure. When the lower square structure moves up and down, the lower limit sleeve moves up and down with the lower limit rod, and then the lower triangular structure moves up and down. Under the limiting conditions of the sliding groove and the sliding bar, the lower triangular structure can only move along the hypotenuse when moving up and down, thus supplementing the lower square structure into a lower trapezoidal structure. The third mounting plate 130 is provided with a lower limit groove 132 for limiting the sliding of the lower square structure in the up and down direction. The lower square structure 510 is provided with a lower limit block 513 corresponding to the lower limit groove 132.

[0039] The drive component 600 is detachably connected to the third mounting plate. The drive component 600 includes four electric actuators: a left electric actuator 610, a right electric actuator 620, an upper electric actuator 630, and a lower electric actuator 640, which are detachably connected to the left sliding component, the right sliding component, the upper sliding component, and the lower sliding component, respectively. The free end of the left electric actuator is detachably connected to the left square structure by bolts. The connection structure between the right sliding component and the right electric actuator is the same as that between the left sliding component and the left electric actuator. The free end of the upper electric actuator is detachably connected to the upper square structure by bolts. The connection structure between the lower sliding component and the lower electric actuator is the same as that between the upper sliding component and the upper electric actuator.

[0040] The outer periphery of the left sliding component, right sliding component, upper sliding component, and lower sliding component are all separately covered with elastic rubber 700 to avoid the reinforcing bars.

[0041] The drive component is protected by a housing 650. The housing of the drive component is equipped with a retractable hook 800 for hanging the drive component on the top reinforcing bars of the reinforcing cage of the cast beam. The base is suspended in use, which facilitates the outward sliding of the left sliding component, right sliding component, upper sliding component and lower sliding component.

[0042] Example 2

[0043] The structure of the concrete partition device for beam-column joint construction in this embodiment is roughly the same as that in embodiment 1, except that: the upper sliding groove is opened on the third mounting plate, the upper limit groove is opened on the second mounting plate, and the connection structure between the upper sliding component and the lower sliding component and the second and third mounting plates is adjusted accordingly.

[0044] Example 3

[0045] The structure of the concrete partition device for beam-column joint construction in this embodiment is roughly the same as that in Embodiment 1, except that the telescopic hook is fixed on the third mounting plate.

[0046] In practical use, a retractable hook is used to hang on the top of the reinforcing cage of the beam to be poured, so that the base is suspended in the air. By controlling the left, right, upper and lower electric push rods, the left, right, upper and lower electric push rods push the left, right, upper and lower square plates to slide outward, while simultaneously moving the left, right, upper and lower triangular plates to form a complete square. The elastic rubber is squeezed when it touches the reinforcing steel, and extends outward in the areas that do not touch the reinforcing steel, cooperating with the formwork outside the reinforcing cage of the beam to form a sealed structure and prevent concrete leakage. After pouring, by controlling the left, right, upper, and lower electric push rods, the left, right, upper, and lower square plates are pushed inward to slide, while simultaneously moving the left, right, upper, and lower triangular plates. After retraction, the base can be removed for reuse, reducing production costs. After pouring, the drive components can be removed before the concrete has completely hardened, improving the turnover rate of the drive components.
