Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to an integral casting mold assembly for culvert covers. Background Technology

[0002] In the construction of settlement joints in the foundation of circular pipe culverts in highway engineering, the traditional construction method is generally the skip-section method, but the construction period is long, labor-intensive, and costly; or pre-embedded steel bars are used to leave reinforcement diaphragms for settlement joints, but improper reinforcement of settlement joint diaphragms can easily cause deformation of the settlement joint diaphragms, and the cost is also high.

[0003] To address the aforementioned issues, existing technology CN209760059U discloses a reinforced concrete circular pipe culvert foundation that utilizes a pre-fixed settlement joint diaphragm before pouring the pipe base concrete to ensure the proper provision of settlement joints; the diaphragm is effectively fixed using pre-embedded angle steel and tie wires, thereby facilitating the pouring of the circular pipe culvert. However, this method is not suitable for pouring slab culvert structures. Therefore, the problem of inconvenience in the overall pouring of slab culverts still needs to be solved.

[0035] Please refer to Figure 1 and Figure 2 This embodiment provides an integral casting mold assembly for a culvert cover, comprising:

[0036] Two wall formwork panels (100), two mating plates (200), settlement joint formwork (300), and fasteners (400);

[0037] Two wall formwork 100s are arranged side by side, with a gap between them to form a settlement joint;

[0038] All mating plates 200 extend along the height direction A of the wall formwork, and the mating plates 200 are located at the edge of one wall formwork 100 near another wall formwork 100;

[0039] Two mating plates 200 are spaced apart to form a slot 21, and the settlement joint template 300 can be set in the slot 21; along the height direction of the mating plates 200, both mating plates 200 are provided with multiple through holes 201; the through holes 201 extend along the length direction B of the wall template.

[0040] The fastener 400 can connect the through holes 201 of the two mating plates 200 respectively, so that the settlement joint template 300 is fastened in the slot 21, or the settlement joint template 300 is disengaged from the slot 21.

[0041] The integral casting mold assembly for the culvert in this solution includes two wall formworks 100, two mating plates 200, a settlement joint formwork 300, and fasteners 400. The wall formworks 100 have gaps between them to form settlement joints, while the slots 21 between the mating plates 200 are aligned with the settlement joints. When the fasteners 400 are connected to the through holes 201 of the two mating plates 200, the settlement joint formwork 300 is stably held in the slots 21, ensuring the straightness of the settlement joint. Compared to existing technologies that involve separately casting the wall at each settlement joint, reducing the need for formwork reinforcement at the settlement joint, this integral casting mold assembly for the culvert improves the common problem of uneven settlement joints caused by formwork bulging, and effectively ensures the on-site construction schedule.

[0042] Please continue reading. Figure 1 , Figure 2 , Figure 3 and Figure 4 To understand more structural details of the integral casting mold assembly for the culvert cover, the mating plate 200 is a long strip plate. In an optional embodiment, the width of each mating plate 200 is the same as its thickness. This reduces interference between the mating plate 200 and the wall formwork 100. In an optional embodiment, the fastener 400 is a tie rod; correspondingly, the through hole 201 of the mating plate 200 is a tie hole. The height direction of the mating plate 200 is the same as the height direction A of the wall formwork.

[0043] In an optional embodiment, the two wall formworks 100 are parallel to each other; and the gap between the two wall formworks 100 remains equal along the height direction A of the wall formworks. This further ensures the straightness of the settlement joint.

[0044] In an optional embodiment, the two mating plates 200 are parallel to each other; and the slots 21 maintain a constant width along the height direction of the mating plates 200. The mating plates 200 match the wall formwork 100 to ensure that the settlement joint can remain straight, thereby ensuring the quality of the culvert after integral casting.

[0045] In an optional embodiment, the mating plate 200 is welded to the wall template 100. It is easy to understand that in other embodiments of this utility model, the mating plate 200 can also be bolted by drilling holes in the side bolt holes of the wall template 100. This is just an example and is not intended to limit the scope.

[0046] In an optional embodiment, both the wall formwork 100 and the mating plate 200 are made of steel. This allows existing steel formwork to be modified to obtain the wall formwork 100 and the mating plate 200, which has the advantages of cost savings and ease of processing and manufacturing.

[0047] In an optional embodiment, through holes 201 are evenly distributed at intervals on the mating plate 200 along its height direction. Optionally, adjacent through holes 201 are kept parallel along the height direction of the mating plate 200. This arrangement ensures that the settlement joint template 300 is uniformly and stably clamped between the two mating plates 200.

[0048] In an optional embodiment, in each mating plate 200, along the height direction of the mating plate 200, one through hole 201 faces the top edge of the wall formwork 100 that mates with the mating plate 200, and another through hole 201 faces the bottom edge of the wall formwork 100 that mates with the mating plate 200. This ensures tight contact between both ends of the wall formwork 100 in the height direction and the slot 21, which is beneficial to ensuring the quality of the culvert after integral casting.

[0049] In summary, this utility model provides an integral casting mold assembly for culvert covers, which has at least the following advantages:

[0050] 1. The integral casting mold assembly for this culvert makes full use of existing templates, has a simple structure, and is easy to install and dismantle.

[0051] 2. The integral casting mold assembly of this culvert has high construction flexibility, and while ensuring construction quality, it is easier to control the quality of the settlement joint.

[0052] 3. Compared with existing formwork, the integral casting mold assembly of this culvert can cast the culvert wall in one go, which can significantly shorten the construction cycle.

[0053] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
