Description

Technical Field

[0001] This application relates to the technical field of double-grate rainwater inlet concrete shaping formwork, and more particularly to a double-grate rainwater inlet concrete shaping formwork for urban roads. Background Technology

[0002] Double-grate concrete formwork is used for the prefabrication of concrete storm drains, which are mainly used in municipal drainage projects, especially in high-rainfall areas that need to withstand large volumes of drainage. These storm drains are typically installed in the drainage systems of public places such as urban roads, squares, and parks to ensure smooth and safe urban drainage.

[0003] Double-grate storm drain inlet concrete formwork typically consists of an outer mold and an inner mold. The outer mold forms the outer contour of the storm drain inlet, while the inner mold shapes the double-grate structure inside. Traditional inner molds are difficult to disassemble due to space constraints, which can easily damage the already poured concrete cross-section. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a concrete formwork template for double-grate storm drains in urban roads.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0007] External template;

[0008] The first right-angled U-shaped plate, the second right-angled U-shaped plate, and the right-angled trapezoidal block are located inside the outer template;

[0009] The second right-angled U-shaped plate has a bevel cut at one end that matches the right-angled trapezoidal block. The first right-angled U-shaped plate, the second right-angled U-shaped plate, and the right-angled trapezoidal block together form an inner template. There are two inner templates, and there is a gap between the two inner templates.

[0010] Optionally, the outer template is formed by two L7-shaped plates.

[0011] Optionally, the outer template and the inner template are connected and fixed by connecting rods.

[0012] Optionally, the upper end face of the outer template is provided with an elongated hole adapted to the bolt, and the upper end faces of the first right-angled U-shaped plate and the second right-angled U-shaped plate are provided with screw holes adapted to the bolt. The connecting rod fixes the outer template and the inner template through the bolt.

[0013] Optionally, each inner template corresponds to two connecting rods.

[0030] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0031] Example 1:

[0032] See Figure 1 A concrete formwork template for double-grate storm drains in urban roads, comprising:

[0033] External template 1;

[0034] The first right-angled U-shaped plate 2, the second right-angled U-shaped plate 3, and the right-angled trapezoidal block 4 are located inside the outer template 1;

[0035] Among them, one end of the second right-angled U-shaped plate 3 is cut with a bevel that matches the right-angled trapezoidal block 4. The first right-angled U-shaped plate 2, the second right-angled U-shaped plate 3 and the right-angled trapezoidal block 4 together form an inner template 5, and two inner templates 5 are provided, with a gap between the two inner templates 5.

[0036] Specifically, the outer formwork 1 forms the outer contour of the drain outlet, while the inner formwork 5 shapes the double-grate structure inside the drain outlet. One end of the first right-angled U-shaped plate 2 is connected to the non-sloping end of the second right-angled U-shaped plate 3, and the other end of the first right-angled U-shaped plate 2 is connected to the right-angled waist of the right-angled trapezoidal block 4. The hypotenuse of the second right-angled U-shaped plate 3 is connected to the hypotenuse of the right-angled trapezoidal block 4. In this way, the three together form the inner formwork 5. During demolding, the right-angled trapezoidal block 4 is removed first to provide the necessary open surface for the removal of the first right-angled U-shaped plate 2 and the second right-angled U-shaped plate 3, thereby facilitating the removal of the entire inner formwork 5 without damaging the cross-section of the poured concrete.

[0037] In addition, the template of this application is made entirely of steel plate and coated with anti-corrosion paint to improve the durability of the template.

[0038] Example 2:

[0039] See Figure 1 and Figure 2 Based on Embodiment 1, optionally, the outer template 1 is formed by two 7-shaped plates.

[0040] Specifically, the two L-shaped panels, when joined together, form a relatively stable structure. This structure better resists deformation under external forces, thus maintaining the overall stability of the formwork. The L-shaped panel design makes the assembly of the outer formwork 1 simple and quick, and the disassembly process is also relatively easy, which helps save construction time and labor costs. In addition, by adjusting the size and shape of the L-shaped panels, the requirements of different construction scenarios can be flexibly met.

[0041] Optionally, the outer template 1 and the inner template 5 are connected and fixed by a connecting rod 6.

[0042] Specifically, the connecting rod 6 tightly connects the outer formwork 1 and the inner formwork 5 together to form a stable overall structure. This helps to resist the lateral pressure generated during concrete pouring, prevents the formwork from deforming or shifting, and thus ensures the relative position and stability of the two during the concrete pouring process, thereby guaranteeing the dimensional and shape accuracy of the final structure.

[0043] Optionally, the upper end face of the outer template 1 is provided with an elongated hole 7 that is compatible with the bolt, and the upper end faces of the first right-angled U-shaped plate 2 and the second right-angled U-shaped plate 3 are provided with screw holes 8 that are compatible with the bolt. The connecting rod 6 fixes the outer template 1 and the inner template 5 by means of the bolt.

[0044] Specifically, the connecting rod 6 has corresponding threaded holes adapted to the bolts. When fixing the inner and outer templates, the bolts are screwed into the threaded holes of the connecting rod 6, the elongated hole 7 of the outer template 1, and the threaded holes 8 of the first right-angle U-shaped plate 2 and the second right-angle U-shaped plate 3, and locked to connect and fix the outer template 1 and the inner template 5. The bolt-connected detachable design ensures efficient and quick fixing, while also facilitating disassembly and reuse.

[0045] Optionally, each inner template 5 corresponds to two connecting rods 6.

[0046] Specifically, the two connecting rods 6 form a more stable connection structure, increasing stress and making the fixation more stable. The two connecting rods 6 can distribute the connection force between the formwork panels, reducing stress concentration at individual connection points, thereby improving the overall connection strength of the formwork system. This helps prevent damage to connection points due to excessive stress, ensuring the safety and reliability of the formwork system. Furthermore, if one connecting rod 6 fails or is damaged, the other connecting rod 6 can still function, ensuring the stability and safety of the formwork system. This helps reduce construction risks and improve the overall structural reliability.

[0047] Optionally, the outer template 1 has several transverse ribs 9 spaced at equal intervals on its outer side wall and several trusses 10 in the longitudinal direction.

[0048] Specifically, the transverse ribs 9 and trusses 10 are provided on the side of the outer formwork 1 to enhance the structural strength and ensure that the formwork body will not deform or shift when pouring concrete.

[0049] Optionally, the outer template 1 has a pre-drilled hole 11 for a rainwater connection pipe, and a portable piston is inserted into the rainwater connection pipe hole 11.

[0050] Specifically, by setting up rainwater connection pipe holes 11 and a portable piston, the holes can be precisely pre-embedded, avoiding the need for later hole construction.

[0051] Optionally, the two 7-shaped plates are connected by a flange plate 12.

[0052] Specifically, the flange connection has high strength and is very convenient to install and disassemble. It only requires tightening or loosening the bolts, which can improve the installation and disassembly efficiency of the outer template 1.

[0053] In this embodiment, during actual construction, the distance between the two inner formwork 5 and the outer formwork 1 is first adjusted, and then the two are fixed. Next, concrete is poured into the formwork body. Once the concrete strength reaches 2.5 MPa or higher, the inner and outer formwork are disassembled to obtain the formed double-grate rainwater inlet.

[0054] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0055] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
