Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a concrete formwork barrier structure for staircase pouring. Background Technology

[0002] A staircase is a passageway that allows people to move smoothly between two spaces. During the concrete pouring process, cement releases gas as it hardens. Simultaneously, the concrete expands and contracts due to temperature changes. Therefore, to prevent voids and air bubbles within the concrete or cracks and deformations caused by thermal expansion and contraction, construction joints are necessary during staircase construction. Existing methods for intercepting construction joints involve using mesh and timber, but these methods are cumbersome to remove during actual construction. Furthermore, when the staircase is long, multiple timber pieces need to be spliced ​​together, which is difficult and results in poor finishing. Therefore, this invention proposes a concrete formwork interception structure for staircase pouring to solve these problems. Utility Model Content

[0040] Please see Figure 2 and Figure 6In the embodiments of this utility model, the assembly component includes a fixing member 20 disposed on one side of the template 10 and a splicing member 2002 disposed on the other side of the template 10. Inserting the splicing member 2002 into the fixing member 20 can quickly connect the two templates 10, which is convenient for the construction of long stairs, and can effectively improve construction efficiency while reducing construction difficulty.

[0041] In an embodiment of this utility model, a splicing groove 2001 is provided on one side of the fixing member 20, and the splicing member 2002 is disposed in the splicing groove 2001 and fits with it with a gap. The splicing groove 2001 has an open arc design. When assembling the two templates 10, the splicing member 2002 on one template 10 is aligned with the splicing groove 2001 on the other template 10 and the splicing member 2002 is inserted downwards completely into the splicing groove 2001.

[0042] It should be emphasized that a limiting groove 2003 is provided on one side of the splicing component 2002, and a plurality of positioning grooves 2004 distributed equidistantly in a circle are provided on one side of the fixing component 20. A limiting component for fixing the splicing component 2002 and the fixing component 20 is provided on one side of the fixing component 20.

[0043] Furthermore, the limiting component includes a fixing plate 2005 disposed on one side of the fixing component 20, a limiting rod 2006 disposed at the center of one side of the fixing plate 2005, a plurality of positioning rods 2007 disposed on one side of the fixing plate 2005 and distributed equidistantly in a circle, and a pull ring 2008 disposed on the other side of the fixing plate 2005.

[0044] It should be understood that the limiting rod 2006 is inserted into the limiting groove 2003 and has a clearance fit with it, and the positioning rod 2007 is inserted into the positioning groove 2004 and has a clearance fit with it.

[0045] Specifically, the working principle of the concrete formwork barrier structure for the staircase is as follows:

[0046] During stair construction, reinforcing bars can be placed in the groove 101. The formwork 10 is used to block the concrete. When setting up the formwork 10, the telescopic rod 1102 can be rotated to adjust its angle so that the support seat 1106 abuts against the contact surface to support the formwork 10, thereby improving the stability of the formwork 10 when blocking the concrete and improving the convenience of subsequent stair pouring operations. In addition, the position of the sleeve rod 1105 on the connecting rod 1104 can be adjusted to adjust the length of the telescopic rod 1102, which can be adjusted according to the construction site. It should be noted that the length of the telescopic rod 1102 should not be changed after the adjustment. Finally, the pin 1202 is inserted into the adjustment hole 12 and the sealing piece 1205 is pressed to connect with the connecting block 1204 to limit the pin 1202 and prevent the pin 1202 from moving out of the adjustment hole 12.

[0047] When the length of the construction staircase is large and a single formwork 10 is insufficient for concrete blocking, multiple formwork 10s can be assembled. Specifically, the splicing piece 2002 on one formwork 10 is aligned with the splicing groove 2001 on another formwork 10, and the splicing piece 2002 is fully inserted downwards into the splicing groove 2001. Then, the positioning rod 2007 is aligned with the positioning groove 2004, and the positioning rod 2007 is fully inserted into the positioning groove 2004. At this time, the limiting rod 2006 is inserted into the limiting groove 2003, and the fixing piece 20 and the splicing piece 2002 are fixed together, thus achieving the purpose of assembling two formwork 10s. This reduces the difficulty of operation, and the assembled formwork 10 has a higher degree of completion, which is conducive to improving the quality of subsequent staircase construction.

[0048] It should be noted that the specific models and specifications of template 10, telescopic rod 1102, connecting rod 1104, sleeve rod 1105, pin 1202, connecting block 1204, and sealing component 1205 need to be selected and determined according to the actual specifications of the device.
