Abstract
Description
Technical Field
[0001] This utility model belongs to the field of prefabricated component technology, specifically relating to a prefabricated component for steel-concrete structure buildings. Background Technology
[0002] Precast columns are often used as temporary support structures in construction projects, temporary facility construction, or equipment installation. However, on hard surfaces such as concrete floors, the stability of precast columns is difficult to guarantee because it is impossible to fix the bottom of the precast columns by digging pits. To solve this problem, it is usually necessary to use wooden poles to support the precast columns after they are erected during construction. Although wooden pole support improves the stability of precast columns to some extent and reduces the risk of them tipping over, the support point between the wooden poles and the precast column is difficult to stabilize and is easily affected by external factors such as wind and vibration, which can easily lead to the failure of the auxiliary support effect of the wooden poles. Therefore, the temporary support of precast columns in the existing technology has the problem of insufficient stability. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated component for steel-concrete structure buildings, which solves the problem of insufficient stability of the temporary support of prefabricated columns in the existing technology.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] Precast components for reinforced concrete structures, including columns;
[0006] The column is placed vertically, and multiple horizontally placed connecting blocks are detachably connected to the peripheral wall near the bottom of the column. The multiple connecting blocks are evenly distributed in a ring around the central axis of the column.
[0007] Each connecting block has a vertically downward-placed sleeve fixedly connected to its lower end face away from the column. Both the upper and lower ends of the sleeve are open, and the lower end face of the sleeve is located above the lower end face of the column.
[0008] Each sleeve has a sliding support column inside, and each connecting block is equipped with an adjustment unit for connecting the support column. The adjustment unit is used to drive the support column to move up and down along the axis of the sleeve, and the lower end of each support column extends out of the sleeve.
[0009] The principle and effect of the above technical solution are as follows:
[0010] The connecting blocks are detachably connected to the columns, facilitating transportation, installation, and disassembly, thus improving construction efficiency. When precast columns are needed for temporary support, the columns are first erected, and then the connecting blocks are installed sequentially on the columns. The support columns are then raised and lowered via an adjustment unit, ensuring that the lower ends of each support column are supported on the ground. This coordinated arrangement of the support columns and the columns effectively prevents the columns from tilting or becoming unstable, improving the stability of the precast column support. Furthermore, multiple support columns can effectively distribute the load, avoiding localized stress concentration. Additionally, if the ground is uneven, adjusting the height of the support columns can compensate for the elevation difference, further enhancing the stability of the column placement.
[0011] The column has multiple grooves on its peripheral wall that are adapted to the connecting blocks. The number of grooves is equal to the number of connecting blocks and they correspond one-to-one. One end of each connecting block is placed in the corresponding groove, and the peripheral wall of the connecting block fits into the peripheral wall of the groove.
[0012] The connecting block is fixed with fixing plates at both the top and bottom ends. When one end of the connecting block is placed in the corresponding groove, the fixing plate fits against the peripheral wall of the column.
[0013] The fixing plates are all connected to the column body by bolts;
[0014] The cross-section of the sleeve along the axial direction is rectangular or elliptical, and the outer peripheral wall of the support column fits against the inner peripheral wall of the sleeve.
[0015] Each adjustment unit includes a vertically downward-placed screw. The peripheral wall of the screw near the top is in the shape of a sliding shaft. The screw is located in the corresponding sleeve. The upper end of the screw is rotatably connected to the corresponding connecting block. The support column is provided with a threaded hole that passes through the upper and lower ends of the support column. The support column is threadedly connected to the screw through the threaded hole.
[0016] Each adjustment unit includes a nut that is fixedly connected to the top of the screw, and the nut is located above the connecting block.
[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0018] Fixed connection: refers to a connection method in which two or more components are tightly connected together by welding, gluing or other methods, and cannot be easily separated.
[0019] Threaded connection: A method of connecting two parts together using a threaded structure. Threaded connections provide a strong connection and are relatively easy to disassemble and reconnect.
[0020] The beneficial effects of this utility model are:
[0021] 1. The connecting blocks are detachably connected to the column, which facilitates transportation, installation and disassembly, and improves construction efficiency. When precast columns are needed for temporary support, the column is first erected, and then each connecting block is installed on the column in sequence. The support column is raised and lowered by the adjustment unit so that the lower end of each support column is supported on the ground. The cooperation between the support column and the column can effectively prevent the column from tilting or becoming unstable, improve the stability of the precast column support, and multiple support columns can effectively distribute the load and avoid local stress concentration.
[0022] Meanwhile, if the ground is uneven, the height difference of the ground can be compensated by adjusting the height of the support column, which can further improve the stability of the column placement.
[0023] 2. By using grooves, connecting blocks, fixing plates, and bolts, a detachable connection between the connecting block and the column can be achieved, which can also improve the stability between the column and the connecting block after connection.
[0024] 3. Through the cooperation of the screw, threaded hole and nut, turning the nut can drive the screw to rotate synchronously. The screw drives the support column to perform threaded transmission in the vertical direction, thereby controlling and adjusting the height of the support column. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] This combination Figures 1 to 5 This document describes an embodiment of a prefabricated component for a reinforced concrete building. Specifically, the prefabricated component is constructed as a split structure, comprising a column 100, connecting blocks 200, sleeves 300, support columns 400, and an adjustment unit. The connecting blocks 200 are detachably connected to the column 100, facilitating transportation, installation, and disassembly, thus improving construction efficiency. When temporary support is required using prefabricated columns, the column 100 is first erected, and then each connecting block 200 is sequentially installed on the column 100. The adjustment unit drives the support columns 400 to adjust their height, ensuring that the lower ends of each support column 400 are supported on the ground. The coordinated arrangement of the support columns 400 and the column 100 effectively prevents the column 100 from tilting or becoming unstable, improving the stability of the prefabricated column support. Furthermore, multiple support columns 400 can effectively distribute the load, avoiding localized stress concentration. Additionally, if the ground is uneven, adjusting the height of the support columns 400 can compensate for the elevation difference, further improving the stability of the column 100.
[0033] Please refer to Figures 1 to 5 Precast components for reinforced concrete structures, including columns 100;
[0034] The column 100 is placed vertically, and multiple horizontally placed connecting blocks 200 are detachably connected to the peripheral wall of the column 100 near the bottom. The multiple connecting blocks 200 are evenly distributed in a ring around the central axis of the column 100.
[0035] The lower end face of the connecting block 200 away from the column 100 is fixedly connected to a vertically downward placed sleeve 300. Both the upper and lower ends of the sleeve 300 are open, and the lower end face of the sleeve 300 is located above the lower end face of the column 100.
[0036] Each sleeve 300 is slidably connected to a support column 400. Each connecting block 200 is equipped with an adjustment unit for connecting the support column 400. The adjustment unit is used to drive the support column 400 to move up and down along the axis of the sleeve 300. The lower end of each support column 400 extends out of the sleeve 300.
[0037] The connecting block 200 is detachably connected to the column 100, which facilitates transportation, installation and disassembly, and improves construction efficiency. When precast columns are needed for temporary support, the column 100 is first erected, and then each connecting block 200 is installed on the column 100 in sequence. The support column 400 is adjusted by the adjustment unit to ensure that the lower end of each support column 400 is supported on the ground. Through the cooperation between the support column 400 and the column 100, the column 100 can be effectively prevented from tilting or becoming unstable, improving the stability of the precast column support. In addition, multiple support columns 400 can effectively distribute the load and avoid local stress concentration.
[0038] Meanwhile, if the ground is uneven, the height difference of the ground can be compensated by adjusting the height of the support column 400, which further improves the stability of the column 100.
[0039] Preferably, the column 100 and the connecting block 200 are both made of steel bars and concrete.
[0040] To improve the stability of the connection between the connecting block 200 and the column 100, a plurality of grooves 101 adapted to the connecting block 200 are provided on the peripheral wall of the column 100. The number of grooves 101 is equal to that of the connecting block 200 and they correspond one-to-one. One end of each connecting block 200 is placed in the corresponding groove 101, and the peripheral wall of the connecting block 200 fits against the peripheral wall of the groove 101. Preferably, the cross-section of the connecting block 200 and the groove 101 is rectangular, which can prevent the connecting block 200 and the groove 101 from rotating relative to each other.
[0041] The connecting block 200 is fixed with a fixing plate 500 at both the upper and lower ends. When one end of the connecting block 200 is placed in the corresponding groove 101, the fixing plate 500 is in contact with the periphery of the column 100.
[0042] By setting the fixing plate 500, the depth of the connecting block 200 inserted into the groove 101 can be effectively controlled. At the same time, the fixing plates 500 at the upper and lower ends of the connecting block 200 fit against the periphery of the column 100, improving the stability of the connecting block 200.
[0043] The fixing plate 500 is connected to the column 100 by bolts 600; the bolts 600 enable the detachable connection between the connecting block 200 and the column 100.
[0044] The cross-section of the sleeve 300 along the axial direction is rectangular or elliptical, and the outer peripheral wall of the support column 400 is in contact with the inner peripheral wall of the sleeve 300; this can prevent the support column 400 from deflecting and sliding inside the sleeve 300.
[0045] Each adjustment unit includes a vertically downward-placed screw 700. The peripheral wall of the screw 700 near the top is shaped like a sliding shaft. The screw 700 is located inside the corresponding sleeve 300. The upper end of the screw 700 is rotatably connected to the corresponding connecting block 200. Each support column 400 has a threaded hole 401. The threaded hole 401 passes through the upper and lower ends of the support column 400. The support column 400 is threadedly connected to the screw 700 through the threaded hole 401. By rotating the screw 700, the screw 700 drives the support column 400 to perform threaded transmission, thereby driving the support column 400 to perform lifting and lowering adjustment.
[0046] Each adjustment unit includes a nut 701 fixedly connected to the top of the screw 700, with the nut 701 located above the connecting block 200; by rotating the nut 701, the screw 700 can be easily rotated.
