Description

Technical Field

[0001] This utility model belongs to the technical field of culvert manufacturing, and in particular relates to a U-shaped component for culverts. Background Technology

[0002] A culvert is typically enclosed by a precast reinforced concrete cover slab, precast reinforced concrete side walls, and a cast-in-place reinforced concrete base slab. In cross-section, it is U-shaped, with the precast reinforced concrete side walls on both sides being symmetrical about the culvert axis.

[0003] The formwork for culvert construction needs to be erected according to the designed structural dimensions. Support systems should be set up on the inner and outer sides of the culvert to ensure the stability of the formwork. Demolding and installation are relatively troublesome and require a lot of manpower and resources. In order to facilitate in-situ demolding and installation and save manpower and resources, we designed a U-shaped component for culverts. It adopts a fully openable and closeable mold. The four sides of the mold are opened and closed by rotating the shaft, and the inner cavity is expanded and contracted by positive and negative threads. This allows for manual in-situ demolding and installation of such large molds, saving manpower and equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a U-shaped component for road culverts, which has a fully openable and closable mold. The four sides of the mold are opened and closed by rotating shafts, and the inner cavity is expanded and contracted by positive and negative threads. This allows for manual in-situ demolding and molding of such large molds, saving manpower and equipment, thus solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A U-shaped component for a culvert includes a base, a supporting template is provided on the top of the base, and movable inner templates are provided at both ends of the supporting template. Side templates are hinged to the front and rear sides of the base. The side templates close to the supporting template and the inner templates are in contact with the supporting template and the inner templates. Side templates are hinged to both sides of the base. Side templates close to the side templates are in contact with the side templates. Multiple internal support tensioning components are provided between the two inner templates. A connector is fixedly connected to the bottom of the inner template. A tensioning screw is rotatably connected to the inner cavity of the connector through a rotating shaft. One end of the tensioning screw extends to the outside of the base. Cavities for the tensioning screw to move are provided on both sides of the bottom of the base. A locking hook assembly is provided between the side templates and the side templates.

[0006] Preferably, the inner support tensioning assembly includes a connecting seat fixedly connected to the opposite side of the two inner templates. The inner cavity of the connecting seat is provided with a limit pin. A threaded rod is fixedly connected to the opposite side of the two limit pins. A threaded tube is threadedly connected to the surface of the two threaded rods.

[0007] Preferably, the top of the connecting seat has a limiting cavity for inserting the threaded rod and the limiting pin, and the limiting pin abuts against the deepest part of the inner cavity of the connecting seat.

[0008] Preferably, the locking hook assembly includes a fixed seat fixedly connected to the front and rear sides of the top of the second side template. A rotatable threaded sleeve is movably connected to the surface of the fixed seat. An external threaded hook is threadedly connected to the inner cavity of the threaded sleeve. Hook pins are fixedly connected to both sides of the top of the first side template, and the external threaded hook is hooked onto the surface of the hook pin.

[0009] Preferably, the top of the base is fixedly connected to a plurality of support piles, and the top of the support piles is fixedly connected to the supporting template.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model unlocks and locks the hook assembly to open the side template 1 and side template 2 by flipping them over. The tension screw is disconnected from the base. Then, by operating the inner support tensioning assembly, the two inner templates bend towards each other, achieving manual in-situ demolding. This avoids consuming too much manpower and resources, thus achieving a mold with full opening and closing. The four-sided mold opens and closes by rotating the shaft, and the inner cavity expands and contracts by positive and negative screws. This allows for manual in-situ demolding and assembly of such large molds, saving manpower and equipment.

[0021] In the following description, embodiments of the U-shaped component for road culverts of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-5 This invention illustrates an embodiment of a U-shaped culvert component, comprising a base 1, a supporting template 2 at the top of the base 1, and multiple supporting piles 10 fixedly connected to the top of the base 1. The tops of the supporting piles 10 are fixedly connected to the supporting template 2. Movable inner templates 5 are provided at both ends of the supporting template 2. Side templates 1 3 are hinged to the front and rear sides of the base 1, with the side of side template 1 3 close to the supporting template 2 and the inner template 5. Side templates 2 4 are hinged to both sides of the base 1, with the side of side template 2 4 close to side template 1 3. Multiple internal support tensioning components 6 are provided between the two inner templates 5. Each internal support tensioning component 6 includes a connecting seat 61 fixedly connected to the opposite side of the two inner templates 5. A limit pin 63 is provided in the inner cavity of the connecting seat 61, and threaded rods 64 are fixedly connected to the opposite side of each of the two limit pins 63. A threaded tube 65 is threadedly connected to the surface of a threaded rod 64. A limiting cavity 62 is provided on the top of the connecting seat 61 for inserting the threaded rod 64 and the limiting pin 63. The limiting pin 63 abuts against the deepest part of the inner cavity of the connecting seat 61. A connecting piece 7 is fixedly connected to the bottom of the inner template 5. A tensioning screw 8 is rotatably connected to the inner cavity of the connecting piece 7 via a rotating shaft. One end of the tensioning screw 8 extends to the outside of the base 1. Cavities for the tensioning screw 8 to move are provided on both sides of the bottom of the base 1. A locking hook assembly 9 is provided between the second side template 4 and the first side template 3. The locking hook assembly 9 includes a fixed seat 91 fixedly connected to the front and rear sides of the top of the second side template 4. A rotatable threaded sleeve 92 is movably connected to the surface of the fixed seat 91. An external threaded hook 94 is threadedly connected to the inner cavity of the threaded sleeve 92. Hanging pins 93 are fixedly connected to both sides of the top of the first side template 3. The external threaded hook 94 is hooked onto the surface of the hanging pin 93.

[0023] Working principle: When using this utility model, according to... Figure 1Concrete is poured during the assembly process. After the concrete solidifies, the threaded sleeve 92 is rotated, causing the external threaded hook 94 to move outward. The threaded sleeve 92 is rotated on the surface of the fixed seat 91, causing the external threaded hook 94 to disengage from the surface of the hook pin 93. Then, the side template 2 4 and side template 1 3 are rotated around the pivot connected to the base 1. The nut on the surface of the tension rod 8 is operated to move away from the base 1. Then, the tension rod 8 is rotated downward, causing it to disengage from the limiting tie between it and the base 1. Next, the threaded tube 65 is rotated, causing the two threaded rods 64 to move towards each other. The threaded rods 64 drive the limiting pin 63 to move within the limiting cavity 62 until the limiting pin 63 pulls the connecting seat 61 to move, causing the two inner templates 5 to move towards each other. The inner templates 5 then pull the tension rod 8 to move within the cavity of the base 1, causing the connection between the inner template 5 and the supporting template 2 to bend towards each other. The culvert above the supporting template 2 can then be removed using tools.

[0024] In summary: This U-shaped culvert component allows for manual in-situ demolding of side templates 3 and 4 by unlocking and locking the hook assembly 9, thereby opening the mold and removing the tensioning screw 8 from the base 1. Then, by operating the inner support tensioning assembly 6, the two inner templates 5 bend towards each other, achieving manual in-situ demolding. This avoids excessive manpower and resources, achieving a fully openable and closable mold. The four-sided mold opens and closes via a rotating shaft, and the inner cavity expands and contracts via positive and negative threads. This allows for manual in-situ demolding and assembly of such large molds, saving manpower and equipment.
