Description

Technical Field

[0001] This utility model relates to the field of airport runway construction technology, and in particular to a spliced ​​airport runway concrete plug template. Background Technology

[0002] In airport concrete pavement construction, the skip-section method is widely used. The pavement section widths are mainly set at 5m, 4.5m, and 4m, and the common construction lengths for a single section are 100m, 120m, and 150m. When a single section reaches its end, a capping formwork is installed and dowel bars are embedded to effectively transfer the load, ensure uniform stress on the pavement panel, and improve the overall structural performance.

[0003] In traditional construction techniques, end cap formwork primarily utilizes wooden or steel formwork support systems. However, given the large scale and complex segmentation of airport pavement projects, custom-made end cap formwork of various lengths is necessary to meet construction requirements based on different pavement widths. Furthermore, airport pavements typically feature longitudinal tongue-and-groove joints; the formwork used during pavement opening is designed with a recessed tongue-and-groove shape, resulting in a protruding tongue-and-groove structure after completion. During the filling phase, the existing pavement sections on both sides directly serve as formwork, requiring no additional support. However, when setting up end cap formwork at the end of a single pavement section, the protruding tongue-and-groove joints on both sides can create spatial conflicts with the end cap formwork, easily leading to tongue-and-groove damage. This, in turn, affects pavement smoothness and structural integrity, reducing the overall quality of pavement construction. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a spliced ​​airport pavement concrete plug template to solve the problems involved in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing airport pavement concrete plug template, including a main template, extension templates on both sides of the main template, and side templates on both sides of the extension templates;

[0006] The main template has first ear plates on both sides, the extension template has second ear plates and third ear plates on both sides respectively, and the side template has a fourth ear plate on one side. The first ear plate, second ear plate, third ear plate and fourth ear plate are all provided with bolt holes.

[0007] The main template and the extension template are connected by a first ear plate and a second ear plate, and the extension template and the side template are connected by a third ear plate and a fourth ear plate.

[0008] Furthermore, the edge template includes a female tongue and groove edge template and a straight edge template, wherein the female tongue and groove edge template is provided with a female tongue and groove.

[0009] Furthermore, the main template and the extension template are provided with force transmission rod holes for fixing the force transmission rod.

[0010] Furthermore, the main template is provided with vertical stiffening plates.

[0011] Furthermore, the vertical stiffening plate is a right-angle plate, with one right-angle side fixed to the main template and the other right-angle side in contact with the ground;

[0012] The vertical stiffening plate is fixed vertically to the main template.

[0013] Furthermore, the vertical stiffening plate is provided with a sleeve, and a positioning pin is inserted into the sleeve and fixed to the ground.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes different splicing combinations to connect the main template with the extension template and side templates, adapting to different pavement widths and allowing for multiple reuses without the need for repeated customization. By using the tongue-and-groove side template, the pavement filling construction can fit snugly against the already constructed pavement tongues and grooves on both sides, reducing damage to the pavement and improving the overall quality of the pavement.

The main formwork 1 is provided with dowel bar holes 11 for fixing dowel bars. The main formwork 1 is provided with vertical stiffening plates 12 to increase overall rigidity. The main formwork 1 is made of steel, with a total length of 3.7m. There are 13 dowel bar holes 11 in total, with a diameter determined according to design requirements, usually 36mm. The spacing of the dowel bar holes 11 is as follows: the middle 11 are 0.3m apart, the rest are 0.25m apart, and the distance between the outermost dowel bar hole and the edge of the main formwork 1 is 0.1m. The extension formwork 2 has 4 holes, is made of steel, with a total length of 0.25m. The distances of the dowel bar holes 11 from the two sides are 0.1m and 0.15m respectively.
