Description

Technical Field

[0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated integrally cast building multi-layer bent frame structure. Background Art

[0002] At present, prefabricated buildings are being promoted from top to bottom in daily construction, and the construction of demonstration cities for building modernization is being increased. Various cities are formulating the scope and goals of implementing prefabricated buildings, and gradually promoting the prefabrication rate of buildings. Generally, the structural system of reinforced concrete factory buildings is a rack structure, a frame structure or a rack structure on a bottom frame.

[0003] In order to ensure the overall stability during the actual construction of the existing frame structure, the construction process is usually cast-in-place reinforced concrete, which is coordinated with the required formwork and supporting scaffolding in the designated area of ​​the factory. Then, a steel cage is placed in the formwork and concrete is poured into the interior. After a certain period of solidification, the workers dismantle the formwork and scaffolding to complete the column casting work. This process wastes too much manpower and material resources as a whole, and the on-site construction labor cost is high. The quality is difficult to control. In addition, during the construction process, it is necessary to wait for the columns to be completely solidified before the next step can be carried out, which leads to a decrease in the overall construction efficiency.

[0004] In summary, the above structure wastes too much manpower and material resources in the actual construction process, and the next step of operation can only be carried out after the columns are completely solidified during the construction process, which reduces the overall construction efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a prefabricated, cast-in-place multi-layer frame structure to solve the technical problems of excessive waste of overall manpower and material resources during the construction process, and the need to wait for the columns to be completely solidified before the next step can be carried out, thereby reducing the overall construction efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a prefabricated cast-in-place multi-story bent frame structure, comprising columns, support columns, and a prefabricated foundation, wherein the columns and support columns are each provided with a connection hole, and a connector is slidably provided in the connection hole, wherein the inner diameter of the connection hole and the outer diameter of the connector are different at both upper and lower ends, the top of the inner diameter of the connection hole is adapted to the bottom of the outer diameter of the connector, and the bottom ends of the inner diameter of the connection hole and the outer diameter of the connector are larger than the top ends; The tops of the columns and support columns are both provided with card slots, in which pressure plates are detachably provided, and the tops of the pressure plates are provided with a plurality of through holes corresponding to the connection holes. The tops of the prefabricated foundations are provided with casting grooves that cooperate with the connection pieces, and the tops of the casting grooves are provided with openings.

[0007] By adopting the above technical solution, a pressure plate is inserted into the top of the column, and the pressure plate will cause the connecting piece to move downward, so that one end of the connecting piece is inserted into the casting groove of the precast foundation, and then concrete is poured inward through the connecting hole, thereby improving the stability between the column and the precast foundation. After the concrete in the connecting hole of the column is cured, the pressure plate is also pressed on the top of the supporting column. During this process, the connecting piece in the supporting column will be inserted into the through hole of the bottom pressure plate by the gravity of the top pressure plate, and then concrete is poured inward through the through hole of the top pressure plate. During this process, the staff can set up multi-layer racks according to actual conditions.

[0008] The present invention is further configured such that prefabricated floor slabs are arranged between the pressure plates, wherein the prefabricated floor slabs are connected in a limiting manner by connecting blocks.

[0009] Preferably, after the installation of the columns is completed, the prefabricated floor slabs are installed between the pressure plates and then limited by connecting blocks. This process makes it convenient for subsequent workers to stand on the top of the prefabricated floor slabs to perform operations and construction, thereby improving the overall practicality of the device.

[0010] The present invention is further configured such that the tops of the upright columns and the supporting columns are both provided with horns, wherein a stress beam is set on the top of the horns, and a plurality of corner braces are set on the bottom of the stress beam, and the corner braces and the stress beam are connected by welding.

[0011] As a preferred embodiment, the setting of the bull horns makes it easier for construction workers to set up stress beams on the side walls of the columns. The corner braces on the stress beams can improve the overall strength of the stress beams and prevent the stress beams from deforming due to the stress themselves.

[0012] The present invention is further configured such that a plurality of purlins are vertically arranged at the bottom of the prefabricated floor slab, and a plurality of cross beams are connected to the bottom of the purlins, wherein the cross beams are horizontally arranged with both ends overlapping the top of the stress beams.

[0013] Preferably, the purlins themselves support the prefabricated floor slabs, and can transfer the force of the prefabricated floor slabs themselves to the bottom beams, and then transfer it to the stress beams through the beams, ensuring the uniformity of the overall force of the floor slabs. The beams and purlins are arranged vertically, which further improves the stability of the prefabricated floor slabs located on the inner side of the pressure plate.

[0014] The present invention is further configured such that ground plugs are symmetrically arranged at the bottom of the prefabricated foundation, and the bottoms of the ground plugs are arranged in a spike shape.

[0015] As a preferred embodiment, the spike-shaped setting makes it easier for construction workers to insert the ground plug into the designated position, improves the convenience of the overall installation, and ensures that the prefabricated foundation itself is in a horizontal setting with the ground.

[0016] The present invention is further configured such that the top of the prefabricated foundation and the bottom of the column, the top of the pressure plate and the bottom of the support column are all connected by high-strength bolt assemblies, and the connection between the two is sealed.

[0017] Preferably, after the workers connect the columns and the precast foundation with high-strength bolt assemblies, when pouring concrete into the interior, leakage of concrete between the two can be prevented, and the concrete can be further ensured to fill the connection holes of the columns and the casting grooves of the precast foundation. The same is true for the support columns and the pressure plates as described above, thereby ensuring the supporting strength of the columns and the support columns themselves.

[0018] The present invention is further configured such that the through holes, the connecting holes and the inner walls of the casting trough are all configured to be smooth.

[0019] As a preferred embodiment, the smooth setting facilitates the concrete pouring process, ensuring that the concrete flows uniformly to the bottom and preventing the concrete from being blocked in the middle of the connecting hole.

[0020] The present invention is further configured such that the prefabricated foundation is configured as a whole in a "convex" shape, and a rough surface is provided on the outer wall of the prefabricated foundation.

[0021] Preferably, after the prefabricated foundation is installed at the designated position through ground plugs, it is fixed by pouring concrete. The convex setting ensures that the prefabricated foundation itself will not tilt, further improving the overall stability.

[0022] The present invention is further configured such that the upright columns and the supporting columns themselves are integrally cast.

[0023] As a preferred embodiment, the connection holes inside the upright column and the support column are ensured to be stable to prevent cracks from occurring during the subsequent opening of the connection holes.

[0024] In summary, the present invention mainly has the following beneficial effects: The present invention embeds the prefabricated foundation in a designated area of ​​the factory building. The columns are transported after being processed remotely. Workers use high-strength bolt assemblies to match the columns with the prefabricated foundation, which reduces the requirements for on-site construction. At the same time, after the columns are installed, the prefabricated floor slabs can be erected and the floor structure superposition layer can be poured as a whole. In this process, the overall workload is reduced, and the construction efficiency, project quality, and construction safety are significantly improved. The present invention provides a connecting hole in the column, wherein the connecting hole and the two ends of the connecting piece are different in size, and the upper inner diameter of the connecting hole is adapted to the outer diameter of the bottom of the connecting piece. During transportation, the bottom end of the connecting piece is always ensured to be in the connecting hole, which facilitates the subsequent assembly of the column and the prefabricated foundation. After the column and the prefabricated foundation are installed, a pressure plate is clamped into the top of the column, and the pressure plate causes the connecting piece to move downward, thereby enabling one end of the connecting piece to be inserted into the casting groove of the prefabricated foundation. Subsequently, concrete is poured inwardly through the connecting hole to flow into the casting groove at the bottom. After the overall solidification is completed, the stability between the column and the prefabricated foundation is improved, and a large amount of manpower and material resources are saved in this process. The present invention provides an array of through holes on the top of the pressure plate. The staff arranges the support columns corresponding to the through holes, and also opens connecting holes in the support columns. After the concrete in the connecting holes of the columns is cured, the pressure plate is also pressed onto the top of the support columns. During this process, the connecting parts in the support columns will be inserted into the through holes of the bottom pressure plate by the gravity of the top pressure plate, and then concrete is poured inwardly through the through holes of the top pressure plate to complete the stability of the support columns at the top of the pressure plate. During this process, the staff can set up multi-layer racks according to actual conditions to form a safe and stable multi-layer rack structure, develop the building into space, and comprehensively improve the utilization efficiency of industrial land.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] See also Figures 1-13 The multi-story bent structure of a prefabricated, integrally cast building shown in FIG1 includes columns 1, support columns 2, prefabricated foundations 3, a casting mechanism, a high-strength bolt assembly, and a lap assembly. Construction workers dig a pit on the site to embed the prefabricated foundation 3, and then place the prefabricated foundation 3 inside the pit. The bottom of the prefabricated foundation 3 is symmetrically provided with ground plugs 13, and the bottom of the ground plugs 13 is in a spike shape. The spike shape facilitates construction workers to insert the ground plugs 13 into designated positions, thereby improving the convenience of overall installation and ensuring that the prefabricated foundation 3 is in a horizontal setting with the ground. The columns 1 and the support columns 2 are cast in an integral molding manner. Construction workers reduce the requirements for on-site construction by transporting the casted columns 1 and support columns 2 to the construction site, and the construction efficiency, quality, and safety of the project are significantly improved. Since the column 1 itself is provided with a connecting hole 9, the connecting hole 9 is set to penetrate the column 1, and the upper and lower ends of the inner diameter of the connecting hole 9 are different, and the inner diameter of the bottom is larger than the inner diameter of the top. At the same time, the connecting piece 10 is inserted into the column 1 through the connecting hole 9, and the upper and lower ends of the outer diameter of the connecting piece 10 are also different, and the outer diameter of the bottom is also larger than the outer diameter of the top. In the connecting hole 9, the outer diameter of the bottom of the connecting piece 10 is adapted to the inner diameter of the top of the connecting hole 9, so that the connecting piece 10 itself can be stuck in the connecting hole 9 and will not move without applying any external force. In this process, it is ensured that the connecting piece 10 itself will not pass through the bottom of the column 1. The construction personnel use the lifting equipment to lift the column 1 as a whole, and then cooperate with the prefabricated foundation 3 on the ground to connect it, and limit the column 1 and the prefabricated foundation 3 by the high-strength bolt assembly; Since a card slot is provided at the top of the column 1, after the installation is completed, the lifting equipment will insert the pressing plate 6 into the card slot at the top of the column 1. During this process, the pressing plate 6 will squeeze the connecting piece 10 extending out of the card slot downward. Since a casting groove 11 that cooperates with the connecting piece 10 is provided at the top of the precast foundation 3, the connecting piece 10 slides downward into the casting groove 11 of the precast foundation 3, and a through hole 8 is provided at the top of the pressing plate 6. The through hole 8 is concentrically arranged with the connecting hole 9 on the column 1. The construction workers can pour concrete into the interior through the through hole 8. At this time, since the connecting piece 10 itself is squeezed downward into the casting groove 11 by the pressing plate 6, the bottom end of the connecting piece 10 will no longer block the top of the connecting hole 9, so the poured concrete will flow downward by its own gravity; Since the top of the casting trough 11 is open, the concrete will be discharged into the casting trough 11 by itself until the connection holes 9 are filled and then the pouring is stopped. After the subsequent overall solidification is completed, the stability between the column 1 and the prefabricated foundation 3 is improved, and a lot of manpower and material resources are saved in this process. After the installation of the column 1 is completed, the prefabricated floor slab 14 can be directly erected and the floor structure superposition layer can be poured as a whole, which reduces the overall workload in this process. The supporting column 2 is also provided with a connection hole 9. After the column is solidified, the pressure plate 6 is pressed on it through the connection hole 9 on the supporting column 2. The through hole 8 is then used to install the support column 2 on the top of the pressure plate 6 through a high-strength bolt assembly. Then a new set of pressure plates 6 will be pressed on the top of the support column 2. During this process, the connector 10 in the support column 2 will be inserted into the through hole 8 of the bottom pressure plate 6 through the gravity of the top pressure plate 6. Then, concrete is poured inward through the through hole 8 of the top pressure plate 6 to complete the stability of the support column at the top of the pressure plate 6. During this process, the staff can set up multi-layer racks according to actual conditions to form a safe and stable multi-layer rack structure, develop the building into space, and comprehensively improve the utilization efficiency of industrial land.

[0030] In the above embodiment, please refer to Figure 2 A prefabricated floor 14 is set between the pressing plates 6, and the prefabricated floor slabs 14 are connected by connecting blocks for limiting the position. After the installation of the columns 1 is completed, the prefabricated floor slabs 14 are installed between the pressing plates 6, and then the prefabricated floor slabs 14 are limited by the connecting blocks. In this process, it is convenient for subsequent workers to stand on the top of the prefabricated floor slabs 14 to operate and construct, thereby improving the practicality of the overall construction of the device.

[0031] In the above embodiment, please refer to Figure 4 and Figure 12The top of the precast foundation 3 and the bottom of the column 1, the top of the pressure plate 6 and the bottom of the support column 2 are all connected by high-strength bolt assemblies, and the connection between the two is sealed. After the staff connects the column 1 and the precast foundation 3 with the high-strength bolt assembly, when pouring concrete into the inside, it can prevent the concrete from leaking between the two, and further ensure that the concrete fills the connection hole 9 of the column 1 and the casting groove 11 of the precast foundation 3. The support column 2 and the pressure plate 6 are the same as above, ensuring the supporting strength of the column 1 and the support column 2 themselves.

[0032] In the above embodiment, please refer to Figure 6 and Figure 9 The through holes 8, the connecting holes 9 and the inner walls of the casting troughs 11 are all smooth. The smooth setting facilitates the concrete pouring process, ensuring that the concrete flows uniformly to the bottom and prevents the concrete from being blocked in the middle of the connecting holes 9. At the same time, the precast foundation 3 is in a "convex" shape as a whole, and a rough surface is provided on the outer wall of the precast foundation 3. After the precast foundation 3 is installed at the designated position through the ground plug 13, it is fixed by pouring concrete. The convex setting ensures that the precast foundation 3 itself will not tilt, further improving the overall stability.

[0033] See also Figure 1 The structure of the prefabricated cast-in-place multi-layer bent frame shown in the figure is similar to that of the first embodiment, wherein the tops of the columns 1 and the support columns 2 are both provided with horns 12, wherein the tops of the horns 12 are provided with stress beams 7, and the bottoms of the stress beams 7 are provided with a plurality of corner braces, and the corner braces and the stress beams 7 are connected by welding. The arrangement of the horns 12 facilitates the construction workers to set up the stress beams 7 on the side walls of the columns, and the corner braces on the stress beams 7 facilitate the improvement of the overall strength of the stress beams, thereby preventing the stress beams 7 from being deformed due to the stress themselves. In this case, a plurality of purlins 4 are vertically arranged at the bottom of the prefabricated floor 14, and a plurality of cross beams 5 are connected to the bottom of the purlins 4. The cross beams 5 are arranged horizontally and overlapped at both ends on the top of the stress beams 7. The purlins 4 themselves support the prefabricated floor 14, and can transfer the force of the prefabricated floor 14 itself to the cross beams 5 at the bottom, and then transfer it to the stress beams 7 through the cross beams 5, thereby ensuring the uniformity of the overall force of the floor. In addition, the cross beams 5 and the purlins 4 are arranged vertically, which further improves the stability of the prefabricated floor 14 located on the inner side of the pressure plate 6.

[0034] The present invention is specifically used in the following manner: when in use, the staff will pre-embed the prefabricated foundation 3 in the designated area of ​​the factory construction, and then use the lifting equipment to transport the processed column 1 to the designated area. At the same time, a connecting hole 9 is opened in the column 1, and the staff will insert the connecting piece 10 into the connecting hole 9. Since the sizes of the connecting piece 10 and the two ends of the connecting hole 9 are different, the upper inner diameter of the connecting hole 9 is adapted to the outer diameter of the bottom of the connecting piece 10. During transportation, it is ensured that the bottom end of the connecting piece 10 is always in the connecting hole 9 and will not fall off. At the same time, the column 1 is connected to the prefabricated foundation 3 by the lifting equipment, and it is limited by the high-strength bolt assembly. Then, the pressing plate 6 is clamped into the top of the column 1. During this process, the pressing plate 6 will squeeze the connecting piece 10 in the connecting hole 9, so that the connecting piece 10 slides downward, and one end thereof will be inserted into the casting groove 11 on the prefabricated foundation 3; After the trough 11 of the upper part 1 is filled with concrete, the concrete will flow to the bottom through the connecting hole 9 until the connecting hole 9 is filled and the pouring is stopped. After the overall solidification is completed, the stability between the column 1 and the precast foundation 3 is improved, and the support column 2 is hoisted to the top of the pressure plate 6, and the connecting hole 9 on the support column 2 will coincide with the through hole 8 at the top of the pressure plate 6. At this time, the support column 2 is limited to the top of the pressure plate 6 by the high-strength bolt assembly, and then a new set of pressure plates 6 will be pressed on the top of the support column 2. During this process, the connecting piece 10 in the support column 2 will be inserted into the through hole 8 of the bottom pressure plate 6 by the gravity of the top pressure plate 6, and then concrete is poured inwardly through the through hole 8 of the top pressure plate 6 to complete the stability of the support column at the top of the pressure plate 6. During this process, the staff can set up multi-layer racks according to actual conditions to form a safe and stable multi-layer rack structure.
