Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically, it relates to a formwork system for inclined columns made of aluminum film panels. Background Technology

[0002] With urban development, building designs are becoming increasingly diverse, and construction difficulties are gradually increasing. Ensuring the forming quality of irregular structural components is a crucial aspect of building quality control. Wooden formwork is widely used in irregularly shaped buildings due to its flexible cutting capabilities, but it suffers from low bending strength, difficulty in construction control, and poor aesthetics. While aluminum formwork offers better forming quality than wooden formwork, it has a low turnover rate and high cost. Using a combination of aluminum and wood can improve forming quality and reduce costs, but the construction process is cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a slanted column aluminum formwork structure. By constructing the template for the slanted column, the required specifications of aluminum formwork in the slanted column can be reduced, the utilization rate of aluminum formwork can be improved, and construction time and costs can be saved.

[0004] To achieve the above objectives, the present invention provides a structural formwork for an inclined column with an irregular shape. The formwork system of the inclined column includes an irregular shape formwork system, which is supported on the inclined surface of the inclined column with an inclined side. The irregular shape formwork system includes a lower formwork system and a top irregular shape formwork, with the top irregular shape formwork located above the lower formwork system. The lower formwork system includes a rectangular formwork group and right-angled trapezoidal formwork located on opposite sides of the rectangular formwork group, with the inclined side of the right-angled trapezoidal formwork located on the side of the inclined column.

[0005] Preferably, the rectangular template group includes at least one main rectangular template.

[0006] Preferably, it further includes at least one auxiliary rectangular template, the width of which is smaller than the width of the main rectangular template; the height of which is the same as the height of the main rectangular template.

[0007] Preferably, the shape of the top irregular template matches the shape of the inclined surface of the inclined column.

[0008] Preferably, the slope of the hypotenuse of the two right-angled trapezoidal templates located on opposite sides of the rectangular template group is the same as the slope of the hypotenuse on opposite sides of the inclined surface of the corresponding inclined column.

[0009] Preferably, the templates of the inclined column template system are connected and fixed by pins; the pins are arranged at intervals in the height direction of the inclined column.

[0010] Preferably, the inclined side of the inclined column is provided with a diagonal brace of the template system supporting the inclined column.

[0011] Preferably, the template system of the inclined column is reinforced by back ribs.

[0012] Preferably, the inclined column base of the inclined column template system is sealed with cement mortar when the gap is less than 2cm, and with wooden strips when the gap is greater than 2cm.

[0013] Preferably, the bottom end face of each template in the inclined column template system that contacts the floor slab or ground is bonded with an elastic gasket, so that the inclined column template system is in close contact with the floor slab or ground.

[0014] The beneficial effects of this invention are:

[0015] This invention utilizes a unique aluminum formwork structure for inclined columns. The inclined columns are supported by a unique formwork system combining rectangular and right-angled trapezoidal aluminum formwork on their two opposite inclined surfaces with inclined sides. The other two sides of the inclined column without inclined sides are supported by normal rectangular aluminum formwork. This allows the rectangular aluminum formwork to be reused repeatedly. Only the right-angled trapezoidal formwork and the top unique formwork need to be fabricated according to the column's slope. This optimizes the splicing of inclined column formwork, reduces the variety of aluminum formwork specifications used in inclined columns, increases the reusability of conventional rectangular aluminum formwork, and saves time and costs.

[0017] Figure label:

[0018] The lower formwork system includes: 1. Rectangular formwork group 10. Main rectangular formwork 101. Auxiliary rectangular formwork 103. Right-angled trapezoidal formwork 104. Top irregular formwork 2. Pins 3. Diagonal braces 4. Diagonal brace supports 5. Back ribs 6. Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention provides a slanted column irregular aluminum mold structure, such as... Figure 1 As shown, the formwork system for the inclined surface of the sloping column includes a lower formwork system 1 and a top irregular formwork 2. Both the lower formwork system 1 and the top irregular formwork 2 are made of aluminum.

[0021] The lower template system 1 includes a rectangular template group 10 and right-angled trapezoidal templates 104 located on opposite sides of the rectangular template group 10.

[0022] The rectangular template group 10 includes at least one main rectangular template 101. When the combined width of the main rectangular template 101 (an integer multiple of its width) and the widths of the right-angled trapezoidal templates 104 on both sides are less than the width of the inclined surface of the inclined column, at least one auxiliary rectangular template 103 needs to be added. The width of the main rectangular template 101 is greater than the width of the auxiliary rectangular template 103, and the main rectangular template 101 and the auxiliary rectangular template 103 have the same height. The rectangular template group 10 is arranged in the opposite direction to the right-angled trapezoidal templates 104 on both sides, and the slope of the hypotenuse of the right-angled trapezoidal template 104 is the same as the slope of the inclined surface of the inclined column where the hypotenuse of the right-angled trapezoidal template 104 is located.

[0023] The templates of the lower template system 1 are connected and fixed together by pins 3. For example, the pins 3 fix the templates of the rectangular template group 10 together, and the right-angled trapezoidal templates 104 on both sides are connected and fixed to the rectangular template group 10 by pins 3. The pins 3 are used to fix and connect the templates, and are arranged at 300mm intervals along the height of the inclined column. They are hammered until there are no gaps between the templates.

[0024] The top irregular formwork 2 is a single piece of formwork whose shape matches the inclined surface of the inclined column. The top irregular formwork 2 is located above the lower formwork system 1. After the top irregular formwork 2 and the lower formwork system 1 are assembled, they form the irregular formwork system of the entire inclined surface of the inclined column. The top irregular formwork 2 is spliced ​​with the bottom formwork of the beam above it.

[0025] On the adjacent sides of the inclined columns, which are non-irregular rectangular structures, rectangular aluminum formwork is used to form a square formwork system. The two sides of the irregular formwork system on the inclined surfaces are located between the square formwork systems on the non-irregular sides of the inclined columns, forming a support.

[0026] Diagonal braces 4 are installed on the side of the inclined column that forms an acute angle with the floor slab or ground. The diagonal braces 4 are located on both sides of the inclined column, providing support for the entire formwork system. One end of the bottom of the diagonal brace 4 is fixed to the diagonal brace support 5 with a pin, and the other end is fixed to the side of the formwork with a pin 3. Adjustable top supports can be added to both ends of the diagonal brace 4 to check and adjust the verticality deviation of the formwork. Reinforcing bars are pre-embedded in the top slab during floor slab pouring as positioning bars to fix the diagonal brace support 5, and the diagonal brace support 5 is fixedly connected to the positioning bars.

[0027] To reinforce the formwork system of the inclined column, several back ribs 6 are set on the outer surface of the inclined column formwork system to reinforce the formwork on each side. The back ribs 6 are set at intervals along the height direction of the inclined column.

[0028] When the slope of the inclined column is very small, the lower formwork system 1 can be supported by only rectangular formwork groups.

[0029] After the formwork system for inclined columns is completed, the column bases need to be sealed. Due to the inclination of the columns, the gaps vary in size, so there are usually three methods for sealing the column bases: when the bottom of the formwork is less than 2cm from the floor slab surface, 1:2 cement mortar is used for sealing; when it is greater than 2cm, wooden strips are used for sealing; an adjustable sealing device can be added to the bottom of the aluminum formwork material during the design process. For example, elastic pads can be set on the lower end face of the aluminum formwork near the floor slab. During formwork erection, the aluminum formwork can be in direct contact with the floor slab surface. The elastic pads are squeezed and deformed under the weight of the formwork, preventing gaps from appearing between the formwork and the floor slab.

[0030] The operation process of this invention:

[0031] First, determine the rectangular formwork group based on the size of the inclined column. Then, determine the right-angled trapezoidal formwork on both sides based on the slope of the inclined column. These are then assembled using pins to form the lower formwork system. According to the drawings, connect the corresponding top irregular-shaped formwork to the lower formwork system using pins to form a complete inclined column aluminum formwork. This process is repeated until all four sides of the inclined column aluminum formwork are assembled. Using pre-embedded steel bars and pins on the floor, diagonal braces are installed on both sides of the inclined column. Adjustable top supports are used to check and adjust the verticality deviation of the formwork. Back bracing is then used to reinforce all components of the aluminum formwork. Finally, the joints at the base of the inclined column are sealed. This formwork construction for inclined columns reduces the number of aluminum formwork sizes used, increases utilization, and saves time and costs.
