Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a device for reusing post-cast concrete support columns. Background Technology

[0002] In civil buildings, post-cast strip support generally adopts the following two methods: one is steel pipe or other steel-type support reinforcement, and the other is plain concrete column independent support.

[0003] For unsupported plain concrete columns, after the post-cast strip is closed and the column reaches its design strength, it is demolished by chipping and breaking it up. This process is time-consuming and labor-intensive, and the resulting solid waste must be removed from the site, which is also time-consuming and labor-intensive, increasing the removal costs. Utility Model Content

[0004] The present invention aims to provide a device for reusing concrete support columns for post-cast strips, in order to solve the problem in the prior art that the post-cast strips are supported by plain concrete columns, and after the support is completed, the plain concrete columns need to be chipped, broken and dismantled. This process is time-consuming and labor-intensive, and the resulting solid waste also needs to be removed from the site.

[0005] This utility model is achieved using the following technical solution: This utility model provides a device for reusing post-cast concrete support columns, including multiple column templates, which are arranged vertically, and the multiple column templates are assembled together to form a vertical cylindrical structure. At least one horizontal dividing joint is provided on a set of column templates arranged opposite to each other. A horizontal dividing plate is inserted into the horizontal dividing joint, and the horizontal dividing plate passes through the corresponding horizontal dividing joints on the two column templates. At least two layers of reinforcing cages are arranged vertically within the space enclosed by all the column formworks, and the reinforcing cages are layered at the horizontal dividing plate; At least one layer of steel reinforcement support components connects a group of column formworks arranged opposite to each other. The lowest steel reinforcement cage is placed on the bottom plate, and the other steel reinforcement cages are threaded through the corresponding steel reinforcement support components. The space enclosed by all the column formwork is used for pouring concrete.

[0006] The post-cast strip concrete support column reuse device of this utility model can pour concrete in the space formed by all column formwork to form a concrete support column, which can meet the support requirements of the post-cast strip. This utility model's post-cast strip concrete support column reuse device involves creating horizontal dividing joints on a set of column formwork. Horizontal dividing plates can be inserted into these joints. After concrete is poured within the space enclosed by the column formwork, the horizontal dividing plates are inserted into the joints before the concrete initially sets, dividing the entire concrete column into at least two segments. Once the entire concrete column has completed supporting the post-cast strip, it can be dismantled. During dismantling, it can be easily separated into at least two concrete segments for reuse, for example, as precast lintels in masonry structures. Compared to existing technologies that directly use plain concrete columns for support and then dismantle them by chipping and breaking them, which is time-consuming, labor-intensive, generates solid waste, and is still time-consuming, labor-intensive, and costly to remove, this utility model's post-cast strip concrete support column, due to the horizontal division by the dividing plates, not only does not affect the support of the post-cast strip but also easily divides it into at least two segments. Dismantling is convenient and quick, with low labor intensity, and the reuse of the segments saves costs.

[0007] Since plain concrete columns cannot withstand horizontal forces, this invention incorporates a reinforcing cage within the space enclosed by the column formwork. This allows the column to achieve horizontal load-bearing capacity, meeting the requirements for precast lintels in masonry structures. While reinforcing cages are typically continuous, this invention arranges them in layers, specifically at the horizontal dividing plate. This facilitates subsequent segmentation, resulting in multiple reinforced concrete segments that can serve as precast lintels in masonry structures. The upper reinforcing cage is then fixed at the target height using reinforcing steel support components mounted on the column formwork.

[0008] The post-cast strip concrete support column reuse device of this utility model can reuse the post-cast strip concrete support column, so that one component has two uses and at least two reinforced concrete segments are obtained. Compared with the existing technology of chipping and breaking up used concrete columns, the reinforced concrete support column of this utility model is easy to divide, simple and convenient to operate, saves time and effort, reduces manpower waste, and can be used as a precast lintel for masonry structure without the need for solid waste transportation, reducing resource waste. It can also reduce the need to prepare precast lintels for masonry structure on the construction site, save costs, reduce manpower and material input, improve efficiency, and shorten the construction cycle.

[0009] As a preferred technical solution: The horizontal dividing joints are horizontal joints, and all the horizontal dividing joints are arranged at vertical intervals along the column formwork.

[0010] As a preferred technical solution: A horizontal dividing joint is provided on a set of column templates arranged opposite to each other, and a horizontal dividing plate is inserted into the horizontal dividing joint; Two layers of steel reinforcement cages are arranged vertically within the space enclosed by all the column formworks, with the two layers of steel reinforcement cages located on the upper and lower sides of the horizontal dividing plate, respectively. A layer of steel reinforcement support components connects a group of column formworks arranged opposite to each other. The steel reinforcement cage located below the horizontal dividing plate is placed on the bottom plate, and the steel reinforcement cage located above the horizontal dividing plate passes through the steel reinforcement support components.

[0011] As a preferred technical solution: The steel cage includes vertically arranged lintel main bars and circumferentially arranged stirrups, and the stirrups are fixedly connected to the lintel main bars; A protective retaining ring is placed on the stirrup.

[0012] As a preferred technical solution: The post-cast strip concrete support column reuse device also includes a formwork reinforcement component, which includes a formwork corner reinforcement component; The template corner reinforcement includes a secondary keel, which is arranged vertically and located at the corner outside the column template. The secondary keel is fixedly connected to the adjacent column template.

[0013] As a preferred technical solution: The template reinforcement component also includes an overall template reinforcement component; The overall reinforcement component of the template includes multiple reinforcing steel pipes, which are arranged horizontally and on the outside of the secondary keel. Opposite groups of reinforcing steel pipes are connected by tie rods. The steel reinforcement support component is fixed to the reinforcing steel pipe.

[0014] As a preferred technical solution: The post-cast strip concrete support column reuse device includes four column templates, and the vertical cylindrical structure formed by the four column templates together has a rectangular cross-section.

[0015] As a preferred technical solution: The column formwork is arranged between the base plate and the top plate, and the column formwork is placed on the base plate.

[0016] As a preferred technical solution: The horizontal dividing plate is made of steel plate.

[0017] As a preferred technical solution: The steel reinforcement support component uses tie rods.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The post-cast strip concrete support column reuse device of this utility model can pour concrete in the space formed by all column formwork to form a concrete support column, which can meet the support requirements of the post-cast strip. This utility model's post-cast strip concrete support column reuse device involves creating horizontal dividing joints on a set of column formwork. Horizontal dividing plates can be inserted into these joints. After concrete is poured within the space enclosed by the column formwork, the horizontal dividing plates are inserted into the joints before the concrete initially sets, dividing the entire concrete column into at least two segments. Once the entire concrete column has completed supporting the post-cast strip, it can be dismantled. During dismantling, it can be easily separated into at least two concrete segments for reuse, for example, as precast lintels in masonry structures. Compared to existing technologies that directly use plain concrete columns for support and then dismantle them by chipping and breaking them, which is time-consuming, labor-intensive, generates solid waste, and is still time-consuming, labor-intensive, and costly to remove, this utility model's post-cast strip concrete support column, due to the horizontal division by the dividing plates, not only does not affect the support of the post-cast strip but also easily divides it into at least two segments. Dismantling is convenient and quick, with low labor intensity, and the reuse of the segments saves costs.

[0019] Since plain concrete columns cannot withstand horizontal forces, this invention incorporates a reinforcing cage within the space enclosed by the column formwork. This allows the column to achieve horizontal load-bearing capacity, meeting the requirements for precast lintels in masonry structures. While reinforcing cages are typically continuous, this invention arranges them in layers, specifically at the horizontal dividing plate.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1 like Figures 1-3 As shown in the figure, this embodiment proposes a device for reusing post-cast strip concrete support columns, including multiple column templates 1, which are arranged vertically, and the multiple column templates 1 are assembled together to form a vertical cylindrical structure.

[0027] Preferably, the post-cast strip concrete support column reuse device includes four column templates 1, and the vertical cylindrical structure formed by the four column templates 1 enclosing and splicing has a rectangular cross-section.

[0028] Preferably, the column template 1 is arranged between the base plate 2 and the top plate, and the column template 1 is placed on the base plate 2.

[0029] In this arrangement, at least one horizontal dividing joint is provided on a set of opposing column templates 1. A horizontal dividing plate 3 is inserted into the horizontal dividing joint, and the horizontal dividing plate 3 passes through the corresponding horizontal dividing joints on the two column templates 1. That is, the horizontal dividing plate 3 is inserted into the horizontal dividing joint on one column template 1 and extends out from the horizontal dividing joint on the opposite column template 1, thereby supporting the horizontal dividing plate 3 at the horizontal dividing joint.

[0030] Preferably, the horizontal dividing plate 3 is made of steel plate.

[0031] Preferably, the horizontal dividing joints are horizontal joints, and all the horizontal dividing joints are arranged at vertical intervals along the column template 1.

[0032] At least two layers of steel cages 4 are arranged vertically within the space enclosed by all the column templates 1, and the steel cages 4 are layered at the horizontal dividing plate 3.

[0033] In this arrangement, at least one layer of steel reinforcement support components 6 connects the relatively arranged column formwork 1. The lowest steel reinforcement cage 4 is placed directly on the base plate 2, and the other steel reinforcement cages 4 are inserted through the corresponding steel reinforcement support components 6. The steel reinforcement cages 4 are fixed at the target height by the steel reinforcement support components 6.

[0034] Preferably, a horizontal dividing joint is provided on a group of column templates 1 arranged opposite to each other, and a horizontal dividing plate 3 is inserted into the horizontal dividing joint; Two layers of steel reinforcement cages 4 are arranged vertically within the space enclosed by all the column templates 1. The two layers of steel reinforcement cages 4 are located on the upper and lower sides of the horizontal dividing plate 3, respectively. A layer of steel reinforcement support components 6 connects a set of column formwork 1 arranged opposite to each other. The steel reinforcement cage 4 located below the horizontal dividing plate 3 is placed directly on the base plate 2, and the steel reinforcement cage 4 located above the horizontal dividing plate 3 is inserted through the steel reinforcement support components 6 and fixed at the target height by the steel reinforcement support components 6.

[0035] The space enclosed by all the column formwork 1 is used for pouring concrete.

[0036] Preferably, the steel bar support component 6 is a tie rod.

[0037] Preferably, the reinforcing cage 4 includes vertically arranged main reinforcing bars 401 and circumferentially arranged stirrups 402. The stirrups 402 are fixedly connected to the main reinforcing bars 401, for example, by binding. A protective layer retaining ring 5 is placed on the stirrups 402. The protective layer retaining ring 5 is used to prevent the reinforcing cage 4 from being tightly pressed against the column formwork 1, ensuring that the reinforcing cage 4 is wrapped with sufficiently thick concrete. Simultaneously, the protective layer retaining ring 5 supports the reinforcing cage 4 between the reinforcing cage 4 and the column formwork 1, fixing the reinforcing cage 4 and preventing displacement or deformation during concrete pouring.

[0038] Preferably, the post-cast concrete support column reuse device further includes a formwork reinforcement component, which includes a formwork corner reinforcement component and a formwork overall reinforcement component. The formwork corner reinforcement component includes a secondary keel 7, which is arranged vertically and located at the corner outside the column formwork 1. The secondary keel 7 is fixedly connected to the adjacent column formwork 1, thus initially fixing the column formwork 1.

[0039] Preferably, the secondary keel 7 is made of rectangular tube or timber, and the rectangular tube or timber is fixedly connected to the column template 1 by screws.

[0040] Preferably, the overall reinforcement component of the template includes multiple reinforcing steel pipes 8, which are arranged laterally and on the outside of the secondary keel 7. A group of opposite reinforcing steel pipes 8 are connected by tie rods 9.

[0041] Preferably, when the reinforcing bar support component 6 adopts a tie rod, the tie rod is pulled on a set of reinforcing steel pipes 8, and the tie rod passes through a set of column templates 1 arranged opposite to each other and is connected between two column templates 1.

[0042] This utility model's post-cast strip concrete support column reuse device involves creating a horizontal dividing joint on a set of column formwork 1. A horizontal dividing plate 3 can be inserted into the horizontal dividing joint. After pouring concrete within the space enclosed by the column formwork 1, the horizontal dividing plate 3 is inserted into the horizontal dividing joint before the concrete initially sets, dividing the entire concrete column into at least two segments. Once the entire concrete column has completed supporting the post-cast strip, it can be dismantled. During dismantling, it can be easily separated into at least two concrete segments for reuse, such as as a precast lintel for masonry structures. Compared to existing technologies that directly support plain concrete columns and then dismantle them by chipping and breaking them, which is time-consuming, labor-intensive, generates solid waste, and is still time-consuming, labor-intensive, and costly to remove from the site, this utility model's post-cast strip concrete support column, due to the horizontal division by the horizontal dividing plate 3, not only does not affect the support of the post-cast strip but also facilitates its separation into at least two segments. The separation is convenient and quick, with low labor intensity, and the segments can be reused, saving costs.

[0043] Since plain concrete columns cannot bear horizontal forces, this invention arranges a reinforcing cage 4 within the space enclosed by the column formwork 1, enabling the column to achieve horizontal load-bearing performance to meet the requirements of precast lintels in masonry structures. Generally, the reinforcing cage 4 is arranged along its entire length; however, considering the subsequent need to divide the reinforced concrete column into at least two segments, this invention arranges the reinforcing cage 4 in layers, specifically at the horizontal dividing plate 3. This facilitates subsequent segmentation, resulting in multiple reinforced concrete segments that can be used as precast lintels in masonry structures. The upper reinforcing cage 4 is fixed at the target height by reinforcing steel support components 6 installed on the column formwork 1.

[0044] The post-cast strip concrete support column reuse device of this utility model can reuse the post-cast strip concrete support column, so that one component has two uses and at least two reinforced concrete segments are obtained. Compared with the existing technology of chipping and breaking up used concrete columns, the reinforced concrete support column of this utility model is easy to divide, simple and convenient to operate, saves time and effort, reduces manpower waste, and can be used as a precast lintel for masonry structure without the need for solid waste transportation, reducing resource waste. It can also reduce the need to prepare precast lintels for masonry structure on the construction site, save costs, reduce manpower and material input, improve efficiency, and shorten the construction cycle.

[0045] The construction method for using the above-mentioned post-cast strip concrete support column reuse device includes the following steps: S1: Preparatory work, including processing column formwork 1 according to drawings, tying steel cage 4, preparing horizontal dividing plate 3, protective layer clips 5, steel reinforcement support components 6, formwork reinforcement components, etc. S2: Install three column formwork pieces 1, and install secondary keel 7 at the corner of the formwork (i.e., where two column formwork pieces 1 are adjacent) to initially fix the three column formwork pieces 1. Install reinforcing steel pipes 8 on the outside of a set of column formwork pieces 1 arranged opposite each other. The reinforcing steel pipes 8 are installed on the outside of the secondary keel 7, and the opposite reinforcing steel pipes 8 are connected by tie rods 9. S3: Install steel cage 4 in the space enclosed by column formwork 1. The bottom steel cage 4 is placed directly on the base plate 2. Install steel support components 6 between a group of column formwork 1 arranged opposite each other. At the same time, pass the upper steel cage 4 through the steel support components 6. Fix the steel cage 4 at the target height through the steel support components 6. Fix the steel support components 6 to the reinforcing steel pipe 8. Then place protective layer clips 5 on the stirrups 402 of the steel cage 4. S4: Install the last column formwork 1. The four column formwork 1s are joined together to form a vertical cylindrical structure. Secondary keel 7 is installed at the corner position. Then, reinforcing steel pipe 8 is installed on the outside of the secondary keel 7. The opposite reinforcing steel pipes 8 are connected by tie rods 9. S5: After the formwork reinforcement is completed, pour concrete in the space enclosed by all column formwork 1. After pouring, before the concrete sets, insert the horizontal dividing plate 3 horizontally into the horizontal dividing joint and pass through the horizontal dividing joint on the two opposite column formwork 1.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
