Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a basement column formwork. Background Technology

[0002] With the acceleration of urbanization and the increasing scarcity of land resources, the expansion of buildings into underground spaces has become a trend. The number and size of basements are constantly increasing. To ensure the stability and safety of the entire building, basement column formwork technology has become particularly crucial. Basement column formwork is a formwork system used to support columns in basements or underground spaces. The main purpose of basement column formwork is to provide support and positioning for columns during the construction of underground structures, and to ensure the accuracy and stability of the columns.

[0003] In the prior art, the basement column formwork includes timber, column template and column hoop. First, steel bars are inserted into the pouring area, then the column template is set up in the pouring area. Next, fixed timber is used to surround the column template to fix it. Finally, the column template is locked with column hoop. Finally, concrete can be poured into the pouring area. For example, see the utility model patent with publication number CN217461468U entitled "A Reinforcement Structure for Concrete Frame Column Template".

[0004] Regarding the aforementioned technologies, in practical applications, there are many specifications for column formwork. When fixing the fixed timber and column formwork, the column hoop uses a pin-fixing method for the adjustment holes, which makes it difficult to accurately meet the stroke required for fixing the column hoop, resulting in poor applicability of the column hoop. Summary of the Invention

[0005] To ensure the applicability of column hoop, this application provides a basement column formwork.

[0006] The technical solution for a basement column formwork provided in this application is as follows:

[0007] A basement column formwork: includes column templates, fixing timber, and column hoop assemblies. The column templates are provided in four pieces, and the inner sides of the four column templates form a concrete pouring area.

[0008] The fixed square timber is provided in several parts, and all of the fixed square timbers are provided outside the column formwork, and all of the fixed square timbers are pressed against the outside of the column formwork.

[0009] The post hoop assembly includes several right-angle post hoops and several connecting threaded sleeves. The post hoop assembly surrounds each fixed square timber. The several right-angle post hoops are all designed with right angles. One end of each right-angle post hoop is provided with a first connecting head, and the other end of each right-angle post hoop is provided with a second connecting head. One end of each connecting threaded sleeve is provided with a first connecting hole, and the other end of each connecting threaded sleeve is provided with a second connecting hole. The first connecting head is connected to the first connecting hole, and the second connecting head is connected to the second connecting hole. Two adjacent right-angle post hoops are connected by connecting threaded sleeves. The connecting threaded sleeves are used to bring the right-angle post hoops connected to both ends of the connecting threaded sleeve closer to each other or further apart.

[0010] By adopting the above technical solution, the concrete pouring area is enclosed in a rectangle using column formwork. Then, the column formwork is secured with fixed square timber. At this time, right-angle column hoops are then fitted. The right-angle column hoops on adjacent sides are connected to each other by connecting bolts. Rotating the connecting bolts on each side makes the right-angle column hoops press against the fixed square timber, so that the column formwork, fixed square timber, and right-angle column hoops press against each other, thereby achieving the effect of fixing the column formwork and improving the stability of the column formwork when pouring concrete.

[0011] Optionally, the first connector is provided with a first thread, the second connector is provided with a second thread, the thread direction of the first thread is opposite to the thread direction of the second thread, the first connecting hole is provided with a first threaded hole, the second connecting hole is provided with a second threaded hole, the thread direction of the first threaded hole is opposite to the thread direction of the second threaded hole, the first connector is threadedly fitted into the first connecting hole, and the second connector is threadedly fitted into the second connecting hole sleeve.

[0012] By adopting the above technical solution, tightening the connecting threaded sleeve can make the right-angle column hoop connected to the first connector and the right-angle column hoop connected to the second connector press against each other, thereby achieving the effect of fixing the column formwork; after the concrete is poured, loosening the connecting threaded sleeve can disassemble the right-angle column hoop at both ends of the connecting threaded sleeve.

[0013] Optionally, several of the fixed square timbers are distributed horizontally on both sides of the connecting screw sleeve. The fixed square timbers are designed as cuboids and are arranged vertically. The right-angle column hoop and column template are both tightly fitted to the fixed square timbers.

[0014] By adopting the above technical solution, the bottom surface of the fixing timber is tightly attached to the ground, the fixing timber is pressed against the column formwork, and the other end of the fixing timber is pressed against the right-angle column hoop. This prevents the column formwork from deforming or bulging due to the lateral pressure of the concrete during the concrete pouring process, ensuring that the column's dimensions meet the design requirements.

[0015] Optionally, the right-angle post hoop is provided with a positioning protrusion, which is used to abut against and fit the fixed square timber.

[0016] By adopting the above technical solution, the fixed square timber can be accurately pressed against the column formwork, and the force applied by the right-angle column hoop can be more evenly distributed to the surface of the column formwork, reducing the possibility of damage to the column formwork caused by excessive local pressure, better protecting the column formwork, and extending the service life of the column formwork.

[0017] Optionally, the fixed square timber is provided with a support member, the support member having a curved groove for placing a right-angle column hoop.

[0018] By adopting the above technical solution, the right-angle column hoop can be pre-placed in the curved groove before installation, reducing the need for construction personnel to lift the column hoop assembly and improving the ease of installation.

[0019] Optionally, the fixed square timber is further provided with a support frame rod, and the support frame rod, the fixed square timber and the ground are connected in a triangular shape.

[0020] By adopting the above technical solution, the support frame can play a supporting role, preventing the poured concrete column from collapsing due to the body and the column shape from not conforming to the expectation.

[0021] Optionally, the column template is a prism, and the cross-section of the column template is trapezoidal.

[0022] By adopting the above technical solution, not only is it easier to install the column formwork, but the contact area between the column formworks can also be increased, thereby enhancing the column formwork's ability to withstand pressure.

[0023] Optionally, the column template is made of wood.

[0024] By adopting the above technical solutions, wood has good workability, and the column template can be flexibly cut according to the specific size and shape requirements of the column. It can be quickly assembled into a column template that meets the design. Moreover, the column template made of wood is relatively lightweight, making it more convenient to install and transport on the construction site, thus improving construction efficiency.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Enclose the area to be poured with concrete using column formwork. Then, use fixed square timber to hold the column formwork in place. Next, install right-angle column hoops. The right-angle column hoops on each side used to fix the column formwork are connected to each other by connecting bolts. Rotate the connecting bolts on each side to make the right-angle column hoops press against the fixed square timber, so that the column formwork, fixed square timber and right-angle column hoops press against each other, thereby achieving the effect of fixing the column formwork and improving the stability of the column formwork when pouring concrete.

[0027] 2. The rotating connecting sleeve allows the right-angle column clamps connected to the first and second connectors to be tightened together, thus securing the column formwork. After the concrete is poured, rotating the connecting sleeve again allows the right-angle column clamps at both ends of the connecting sleeve to be removed.

[0028] 3. This allows the fixing timber to be accurately pressed against the column formwork, and the force applied by the right-angle column hoop can be more evenly distributed to the formwork surface, reducing the possibility of excessive local pressure causing damage to the formwork, better protecting the formwork, and extending the service life of the formwork.

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a basement column mold for forming a quadrangular prism. (See also...) Figure 1 The basement column formwork includes column formwork 1, fixed square timber 2, and column hoop assembly 3;

[0039] Reference Figure 2The column formwork 1 consists of four pieces, each with a trapezoidal cross-section. Two adjacent column formwork pieces 1 are connected at right angles via prism sides. The four pieces form a rectangle, enclosing a concrete pouring area for shaping the quadrangular prism. The prism design of the column formwork 1 improves the ease of use around the concrete pouring area and increases the contact area between adjacent pieces, thereby enhancing its pressure resistance. The column formwork 1 is made of wood, which has good workability. It can be cut to the required column dimensions, allowing for quick assembly into a formwork that conforms to the design. Furthermore, the relatively lightweight wooden formwork 1 facilitates installation and transportation on-site, improving construction efficiency.

[0040] Reference Figure 3 and Figure 4 There are four sets of fixed square timbers 2, each set corresponding to one of the column formwork 1. Each set has four fixed square timbers 2, distributed horizontally, with each set corresponding to one column formwork 1 on one side. The fixed square timbers 2 are rectangular and vertically positioned on the outside of the column formwork 1. Each set of fixed square timbers 2 is tightly pressed against the column formwork 1, and this close fit enhances the overall rigidity of the column formwork 1, preventing deformation or bulging due to lateral pressure from the concrete during pouring. This ensures that the column's dimensions meet design requirements and guarantees the flatness and verticality of the column's appearance.

[0041] Reference Figure 3 and Figure 4 The fixed square timber 2 is provided with a support member 21, and the support member 21 is provided with a curved groove 201. The column hoop assembly 3 can be placed in the curved groove 201. When using the column hoop assembly 3 to reinforce the column template 1, the column hoop assembly 3 can be placed in the curved groove 201 opened in the support member 21 in advance to reinforce the column template 1, so as to reduce the occurrence of multiple construction workers cooperating to lift the column hoop assembly 3, thereby improving the convenience of installing the column hoop assembly 3.

[0042] This utility model also includes four support rods 22, each corresponding to a column template 1 and rotatably connected to a fixed square timber 2. One end of each support rod 22 connected to the bottom surface has a base plate, which increases the contact area between the support rod 22 and the ground. The support rod 22, the fixed square timber 2, and the ground form a triangular connection. Specifically, the top of the support rod 22 is hinged to the fixed square timber 2, and the bottom of the support rod 22 is inclined to the ground, thereby increasing the support efficiency of the support rod 22 for the column template 1 and preventing the poured concrete column from collapsing due to body shape issues, thus ensuring the main body shape matches expectations.

[0043] Reference Figure 4 , Figure 5 as well as Figure 6 The post clamp assembly 3 comprises several sets, distributed vertically. Each post clamp assembly 3 surrounds a fixed square timber 2 and includes a right-angle post clamp 31 and a connecting threaded sleeve 32. The right-angle post clamp 31 is designed in a right-angle shape. One end of the right-angle post clamp 31 has a first connector 33 with a first thread, and the other end has a second connector 34 with a second thread. One end of the connecting threaded sleeve 32 has a first connecting hole 301 with a first threaded hole adapted to the first thread, and the other end has a second connecting hole 302 with a second threaded hole adapted to the second thread.

[0044] One of the adjacent right-angle column hoops 31 is connected to one end of the connecting sleeve 32 via a first thread, and the other right-angle column hoop 31 is connected to the other end of the connecting sleeve 32 via a second thread, so that the two adjacent right-angle column hoops 31 are threadedly connected by the connecting sleeve 32. The thread direction of the first threaded hole is opposite to that of the second threaded hole, so that turning the connecting sleeve 32 will cause the right-angle column hoops 31 at both ends of the connecting sleeve 32 to move closer or further apart. As the connecting sleeve 32 is tightened, the right-angle column hoops 31 at both ends continue to move closer, so that the column formwork 1, the fixed square timber 2, and the right-angle column hoops 31 continuously abut against each other, thereby achieving the effect of fixing the column formwork 1 and improving the stability of the column formwork 1 when pouring concrete. After the pouring is completed, the connecting sleeve 32 can be loosened to continuously move the right-angle column hoops 31 at both ends further apart, thereby achieving the effect of disassembling the column hoop assembly 3.

[0045] Reference Figure 7 The right-angle column hoop 31 is provided with a positioning protrusion 35, which is used to abut against the fixed square timber 2. When using the column hoop assembly 3 to reinforce the fixed square timber 2, the positioning protrusion 35 can restrict the movement of the fixed square timber 2 in advance, so that the fixed square timber 2 can accurately abut against the column formwork 1. This can distribute the force applied by the right-angle column hoop 31 more evenly to the surface of the column formwork 1, reduce the possibility of damage to the column formwork 1 due to excessive local pressure, better protect the column formwork 1, and extend the service life of the column formwork 1.

[0046] The implementation principle of a basement column formwork according to an embodiment of this application is as follows: During construction, firstly, column formwork 1 is used to enclose the concrete pouring area, and then fixed square timber 2 is used to tighten the column formwork 1. At this time, four right-angle column hoops 31 are used to enclose the fixed square timber 2. Then, the right-angle column hoops 31 are placed in the curved groove 201 at the support member 21, and two adjacent right-angle column hoops 31 are connected with connecting screw sleeves 32. At this time, the positioning protrusion 35 of the right-angle column hoops 31 is engaged with the fixed square timber 2. By tightening the connecting screw sleeves 32, the column formwork 1, the fixed square timber 2 and the right-angle column hoops 31 are continuously pressed against each other, thereby achieving the effect of fixing the column formwork 1. Finally, concrete pouring can be carried out. After the pouring is completed, the connecting screw sleeves 32 can be loosened to continuously move the right-angle column hoops 31 at both ends away, thereby achieving the effect of disassembling the column hoop assembly 3. Then, the fixed square timber 2 and the column formwork 1 are disassembled in sequence.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
