Description

Technical Field

[0001] The present application relates to the technical field of building formwork, and in particular to an aluminum formwork installation structure. Background Art

[0002] Aluminum formwork is widely used due to its high standardization and quick construction. When installing aluminum formwork, first assemble and fix a row of aluminum formwork, then insert the pull tabs into the pull tab slots reserved in the aluminum formwork. The mounting hole on one end of the pull tab is connected to the connection hole of the aluminum formwork. After all the pull tabs are inserted into place, use pins to pass through the aluminum formwork and the pull tabs, insert the pins into the pins to fix the aluminum formwork and the pull tabs, and then install another row of aluminum formwork. The spacing between the two rows of aluminum formwork is the thickness of the wall. When installing another row of aluminum formwork, first insert pins into the pull tabs in the first row. Then, when installing a new aluminum formwork, insert the pins into the mounting holes on one side of the aluminum formwork, insert the pins into the pins, and continue inserting pins on the other side of the aluminum formwork. The pins also pass through the corresponding pull tabs, and then take another aluminum formwork to install and fix.

[0003] After the pin passes through the aluminum template and the pull tab, it waits for the other aluminum template to cooperate with the pin. The pin is only plugged into the installed aluminum template and the pull tab. During the installation of another aluminum template, when the aluminum template being installed approaches the pin, there is a possibility of collision with the pin, causing the pin to fall off. Utility Model Content

[0004] In order to improve the connection relationship between the pins and the pull tabs, the present application provides an aluminum template installation structure.

[0005] This application provides an aluminum template installation structure, which adopts the following technical solutions:

[0006] An aluminum template installation structure includes an aluminum template and a pull tab. The aluminum template is spliced ​​into multiple pieces. The pull tab is inserted between two adjacent aluminum templates. The aluminum template is provided with a pull tab groove for inserting the pull tab. A pin is passed through the aluminum template and the pull tab. The pull tab is provided with a mounting hole. The pull tab has a tooth plate extending from the inner wall of the mounting hole. The tooth plate includes a tooth root and a tooth top. The tooth plates are circumferentially distributed along the inner circumference of the mounting hole. The diameter of the tooth top circle is smaller than the outer diameter of the pin, and the diameter of the tooth root circle is larger than the outer diameter of the pin.

[0007] By adopting the above technical solution, the aluminum formwork installation structure achieves rapid installation and removal by splicing multiple aluminum formwork pieces and tabs together, and securing them with pins. The tab slot design allows for easy insertion of the tab into the aluminum formwork, while the teeth extending from the inner wall of the mounting hole, in conjunction with the pins, enhance the stability of the connection. The diameter of the tooth top circle is smaller than the outer diameter of the pin, allowing the pin to squeeze the teeth during insertion, generating a certain preload force, strengthening the connection between the pin and tab, and thus improving the overall connection strength.

[0008] Optionally, the teeth are evenly spaced along the inner circumference of the mounting hole.

[0009] By adopting this technical solution, the teeth are evenly spaced along the inner circumference of the mounting hole, ensuring that the pin is evenly stressed during insertion, preventing loosening or damage to the connection caused by uneven force. This even distribution also improves the stability and reliability of the connection, making the aluminum formwork installation structure more secure.

[0010] Optionally, the tooth plate includes a first tooth plate and a second tooth plate, and the tooth top circle diameter of the first tooth plate is smaller than the tooth top circle diameter of the second tooth plate.

[0011] By adopting the above technical solution, by designing the first and second sprockets with a smaller diameter of the first sprocket's tip circle than the second sprocket's tip circle, different tightening degrees can be achieved. When a higher tightening force is required, the pin's outer diameter is selected to be larger than the second sprocket's diameter, causing both the first and second sprockets to be deformed to different degrees. This design increases installation flexibility and adaptability.

[0012] Optionally, the first tooth plate and the second tooth plate are staggered.

[0013] By adopting the above technical solution, the staggered distribution of the first and second teeth further improves the stability and shear resistance of the connection. The staggered distribution allows the teeth to form a more complex stress distribution when subjected to force, thereby improving the overall anti-destruction ability.

[0014] Optionally, one of the first tooth plates and one of the second tooth plates are combined into a group of tooth plate combinations, and the tooth plate combinations are evenly spaced along the inner circumference of the mounting hole.

[0015] By adopting the above technical solution, a first tooth plate and a second tooth plate are combined into a tooth plate combination, and are evenly spaced along the inner circumference of the mounting hole. This design ensures both a stable connection and adjustable tightening. By adjusting the number and type of tooth plate combinations, the tightening requirements of different installation needs can be met.

[0016] Optionally, the thickness of the tooth piece is smaller than the thickness of the pull tab.

[0017] By adopting the above technical solution, the thickness of the teeth is smaller than that of the pull tab, making it easier for the teeth to elastically deform when subjected to force, thereby increasing the flexibility and adaptability of the connection. This design helps to reduce the damage to the connection caused by installation errors or external impacts.

[0018] Optionally, the pin includes an end cap and a pin rod, the outer diameter of the pin rod gradually decreases along the length direction of the pin rod, and the end of the pin rod with the largest outer diameter is fixedly connected to the end cap.

[0019] By adopting the above technical solution, the end cover and pin rod of the pin are designed, in which the outer diameter of the pin rod gradually decreases along the length direction, so that the pin can gradually squeeze the tooth plate when penetrating into the mounting hole, generating a more uniform pre-tightening force, and the pin can also be better withdrawn during the disassembly of the aluminum template.

[0020] Optionally, the pull tab includes a first connecting section and two second connecting sections, the two second connecting ends are respectively fixedly mounted on the ends of the first connecting section, the connecting portion of the first connecting section and the second connecting section is provided with a broken groove, and the broken grooves are spaced apart along the width of the pull tab.

[0021] By adopting the above technical solution, the first connecting section and the second connecting section of the pull tab are designed, and the broken groove is opened, the pull tab can also pull the two aluminum formworks together. When the aluminum formworks are dismantled, the second connecting section located outside the concrete wall can be easily broken, thereby speeding up the dismantling process.

[0022] In summary, this application has at least one of the following beneficial effects:

[0023] 1. The coordinated design of pull tabs, pins, and teeth enables quick installation and removal of the aluminum formwork installation structure, while also improving the stability and reliability of the connection. This design ensures that the aluminum formwork maintains high stability and safety during installation and use.

[0024] 2. By designing different sizes and types of teeth and adjustable tightening levels, installation flexibility and adaptability are achieved. This design enables the aluminum formwork installation structure to meet the tightening requirements of different installation needs, improving installation efficiency and accuracy.

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] The embodiment of the present application discloses an aluminum template installation structure.

[0035] Example 1

[0036] Reference Figure 1 Example 1 discloses an aluminum formwork installation structure, comprising a plurality of aluminum formworks 1 joined together, and a pull tab 2 inserted between two rows of aluminum formworks 1. The aluminum formworks 1 are provided with a pull tab slot 12 for inserting the pull tab 2, so that when the aluminum formworks 1 are joined together, two adjacent aluminum formworks 1 in the same row can be in close contact with each other. The aluminum formworks 1 are generally joined in two rows, with the spacing between the two rows of aluminum formworks 1 being the thickness of the concrete wall. One end of the pull tab 2 is mounted on one row of aluminum formworks 1, and the other end of the pull tab 2 is mounted on the other row of aluminum formworks 1, thereby achieving a counter-pulling effect for the pull tab 2 and increasing the connection strength of the aluminum formworks 1.

[0037] Reference Figure 1 and Figure 2When the two aluminum templates 1 are attached to each other and the pull tab 2 is inserted, the mounting hole 21 of the pull tab 2 and the connection hole 11 of the aluminum template 1 are connected to each other. The aluminum template 1 and the pull tab 2 are inserted through the pin 3. The pin 3 passes through the two aluminum templates 1 and the pull tab 2 and then inserts into the pin piece 4. The cooperation between the pin 3 and the pin piece 4 fixes the aluminum templates 1 together. The pin piece 4 is a wedge-shaped block. After the pin piece 4 is inserted into the pin 3, it contacts the aluminum template 1.

[0038] When installing the aluminum templates 1, first assemble and secure a row of aluminum templates 1. Then, insert the pull tabs 2 into the pull tab slots 12 reserved in the assembled aluminum templates 1, ensuring that the mounting holes 21 at one end of the pull tabs 2 are connected to the connection holes 11 of the aluminum templates 1. After all the pull tabs 2 are fully inserted, use pins 3 to pass through the aluminum templates 1 and the pull tabs 2, and insert the pins 4 onto the pins 3 to securely connect the aluminum templates 1 and the pull tabs 2. Then, install another row of aluminum templates 1, with the spacing between the two rows of aluminum templates 1 being the wall thickness.

[0039] When installing another row of aluminum templates 1, first penetrate the pin 3 on the first row of pull tabs 2. Then, when installing the first aluminum template 1, the pin 3 passes through the mounting hole 21 on one side of the aluminum template 1, and then the pin piece 4 is inserted into the pin 3. Insert the pin 3 to the other side of the aluminum template 1, and the pin 3 passes through the corresponding pull tab 2. Continue to install the second aluminum template 1, so that the pin 3 passes through one side of the second aluminum template 1 and then the pin piece 4 is inserted.

[0040] During the installation of the second aluminum template 1, the pin 3 is easily pushed away from the pull tab 2 and the first aluminum template 1. To reduce the possibility of the pin 3 passing through the pull tab 2 and then leaving, the simplest method is to first connect the connecting holes 11 of the two adjacent templates with the installation holes 21 of the pull tab 2, then install the pin 3, and then insert the pin 4.

[0041] Reference Figure 3 , the embodiment of the present application also provides another way to install the pin 3. The pull tab 2 has a tooth piece 5 extending from the inner wall of the mounting hole 21. The tooth piece 5 includes a tooth root 51 fixedly connected to the inner wall of the mounting hole 21 and a tooth top 52 away from the inner wall of the mounting hole 21. The diameter of the tooth top circle 53 is smaller than the outer diameter of the pin 3, and the diameter of the mounting hole 21 is larger than the outer diameter of the pin 3. When the connection hole 11 of an aluminum template 1 is connected to the mounting hole 21 of the pull tab 2, the tooth piece 5 is squeezed when the pin 3 passes through the pull tab 2, generating a certain pre-tightening force, increasing the connection relationship between the pin 3 and the pull tab 2, and then another aluminum template 1 is installed, which facilitates the rapid alignment and installation of the two adjacent aluminum templates 1, speeds up the installation speed, and also increases the connection strength of the entire aluminum template 1 structure.

[0042] Reference Figure 3 and Figure 4The teeth 5 are evenly spaced along the inner circumference of the mounting hole 21. Their thickness is smaller than that of the pull tab 2, allowing them to more easily elastically deform when subjected to force, thereby increasing the flexibility and adaptability of the connection. This design helps reduce damage to the connection caused by installation errors or external impacts.

[0043] Reference Figure 5 In order to ensure that the pin 3 can be smoothly inserted into the pull tab 2 and quickly withdrawn from the pull tab 2, the pin 3 includes an end cap 31 and a pin rod 32. The outer diameter of the pin rod 32 gradually decreases along the length of the pin rod 32, and the end of the pin 3 with the largest outer diameter is fixedly connected to the pin cap.

[0044] When the pin 3 is inserted into the mounting hole 21, it can evenly squeeze the tooth piece 5. When leaving the pull tab 2, when the contact part of the pin rod 32 and the tooth piece 5 is separated, a gap is left between the other part of the pin rod 32 and the deformed tooth block, which facilitates the pin 3 to smoothly exit the pull tab 2.

[0045] Reference Figure 4 Furthermore, in order to facilitate people to knock off the pull tab 2 extending out of the concrete wall, the pull tab 2 includes a first connecting section 22 and two second connecting sections 23. The ends of the first connecting section 22 in the length direction are fixedly connected to the second connecting sections 23, and the first connecting section 22 and the second connecting section 23 are formed in one piece. The length of the first connecting section 22 is greater than the length of the second connecting section 23, and the width of the first connecting section 22 is less than the width of the second connecting section 23. Pull tabs 2 of different specifications have different lengths of the first connecting section 22, and the lengths of the second connecting sections 23 can be the same. The appropriate pull tab 2 is selected according to the thickness of the concrete to be poured. The connecting part of the first connecting section 22 and the second connecting section 23 is provided with a breaking groove 24, and the breaking grooves 24 are spaced apart along the width direction of the pull tab 2. The provision of the breaking groove 24 facilitates breaking or knocking off the second connecting section 23, so that the first connecting section 22 is stably located in the concrete wall.

[0046] Example 2

[0047] Reference Figure 6 The difference between Example 2 and Example 1 lies in the different structure and distribution of the tooth pieces 5. The other structures and principles are essentially the same. The tooth pieces 5 of Example 2 include a first tooth piece 6 and a second tooth piece 7. The diameter of the tooth tip circle 53 of the first tooth piece 6 is smaller than that of the second tooth piece 7. The arrangement of the first tooth piece 6 and the second tooth piece 7 can better accommodate pins with different outer diameters and achieve different tightening levels.

[0048] For example, if the outer diameter of the pin 3 is only slightly larger than the diameter of the first tooth piece 6, only the first tooth piece 6 is squeezed and deformed, resulting in a moderately tight connection between the pin 3 and the pull tab 2. If the outer diameter of the pin 3 is larger than the diameter of the second tooth piece 7, both the first and second tooth pieces 6 and 7 are squeezed and deformed, thereby increasing the tightness of the connection between the pin 3 and the pull tab 2. If the first and second tooth pieces 6 and 7 are squeezed and deformed to different degrees, with the second tooth piece 7 being less deformed, the pin 3 and the pull tab 2 can maintain a high degree of tightness, and the pin 3 can be inserted into the mounting hole 21 with less effort.

[0049] Reference Figure 6 The first and second teeth 6 and 7 are staggered. When the pin 3 is inserted into the pull tab 2, the central axis of the pin 3 and the centerline of the mounting hole 21 of the pull tab 2 substantially coincide. The pin 3 can evenly squeeze the first and second teeth 6 and 7. This staggered arrangement creates a more complex stress distribution when the first and second teeth 6 and 7 are subjected to force, thereby improving the overall anti-destruction capability.

[0050] Reference Figure 6 and Figure 7 Furthermore, a first tooth piece 6 and a second tooth piece 7 are combined to form a tooth piece 5 combination. The tooth piece 5 combination can be evenly spaced or continuously distributed along the inner circumference of the mounting hole 21. In the embodiment of the present application, the tooth piece 5 combination is preferably evenly spaced along the inner circumference of the mounting hole 21. This allows the pin 3 and the pull tab 2 to form a fastened connection relationship while reducing the manufacturing material.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
