Description

Technical Field

[0001] This utility model belongs to the technical field of concrete pouring molds. Specifically, it relates to a vertical pouring template for arc-shaped components. Background Technology

[0002] With the development of Chinese society and the improvement of people's living standards, there is a growing demand for leisure and entertainment venues that offer a green and healthy natural environment. To improve service quality, respond to the call for rural revitalization, and promote the development of the tourism industry, providing convenient, comfortable, and quick-to-use agritourism housing is particularly important. The houses are designed in a circular shape and can accommodate facilities such as bathrooms, air conditioning, lighting, and beds. Therefore, designing a steel structure model for prefabricated agritourism housing is of great significance for the prefabrication and production of components for agritourism housing.

[0003] Currently, precast tunnel segments produced domestically are widely used in rail transit, urban construction, water conservancy projects, and bridges and tunnels. As a high-precision precast concrete component, the tunnel segment is the main body of the tunnel structure, needing to withstand external soil pressure, groundwater pressure, and various dynamic loads within the tunnel. Its quality directly affects the overall safety of the tunnel. Reinforced concrete tunnel segments have a certain strength, are relatively easy to process and manufacture, are corrosion-resistant, and have low cost, making them the most commonly used type of tunnel segment. The production method for precast tunnel segments is mostly flat-mold production, where concrete is poured horizontally onto a mold platform. The disadvantages of this mold platform production method are its large footprint. Furthermore, when using a mold platform, since the bottom surface of the component is the mold platform surface, the upper pouring surface needs to be treated. The large surface area makes it difficult to guarantee and control quality, resulting in poor surface roughness and flatness. For tunnel segment component housing used for accommodation, higher standards and requirements will be placed on surface smoothness, overall aesthetics, and safety performance.

[0004] Therefore, in response to the above problems, a model of a segmented house component specifically designed for tourist accommodation in the tourism industry was created and manufactured. In the current rapidly developing tourism industry market, it has great potential for promotion and application. Utility Model Content

[0019] Example 1: See attached Figures 1-4A vertical casting template for arc-shaped components is assembled from an arc-shaped inner mold 1, an arc-shaped outer mold 2, an arc-shaped bottom mold, and end molds 3 on both sides. The vertical arrangement, with its long sides set vertically, reduces the surface area of ​​the casting template, effectively controlling the flatness of the cast product's surface. A traveling mechanism is provided on the arc-shaped inner mold 1 and the arc-shaped outer mold 2 to facilitate movement during molding and demolding. The traveling mechanism includes an outer mold traveling frame located outside the arc-shaped outer mold 2 and an inner mold traveling frame located outside the arc-shaped inner mold 1. The outer side refers to the outer side that forms the overall casting template. Both the outer mold traveling frame and the inner mold traveling frame include two vertical support rods 4 and two horizontal support rods 5. The two vertical support rods 4 on the arc-shaped outer mold 2 are parallel to each other on the outer side, and their bottoms are respectively connected to two horizontal support rods 5, which extend outwards. Correspondingly, pulley sets are provided at the bottom of the arc-shaped outer mold 2, the arc-shaped inner mold 1, and the bottom of the horizontal support rod 5, forming a stable movable structure for the arc-shaped outer mold 2 and the arc-shaped inner mold 1. A track frame 13 is installed on the ground, and the track frame 13 is provided with a walking track corresponding to the pulley set. The pulley set includes guide wheels and walking wheels, which can ensure that it slides in cooperation with the walking track and does not derail. A counterweight structure can be set at the end of the horizontal support rod 5 away from the vertical support rod 4 to ensure more stable movement of the arc-shaped outer mold 2 and the arc-shaped inner mold 1. The arc-shaped bottom mold can be pre-installed integrally at the bottom of the arc-shaped inner mold 1 or the arc-shaped outer mold 2. In this embodiment, it is integrally installed on the arc-shaped outer mold 2. When the arc-shaped inner mold 1 and the arc-shaped outer mold 2 move and cooperate through their respective walking frames, the arc-shaped bottom mold and the inner side of the arc-shaped inner mold 1 are contacted for initial positioning. The two end molds 3 are rotatably connected to both sides of the arc-shaped outer mold 2. In this embodiment, they are connected by hinges. After initial positioning, the rotating end molds 3 cooperate with the arc-shaped inner mold 1 to form a vertical arc-shaped pouring template with an open top surface. Concrete is poured inward from the top surface for pouring.

[0020] In this embodiment, the top and bottom of the vertical support rod 4 are provided with locking holes. The arc-shaped outer mold 2 and the arc-shaped inner mold 1 are one-to-one corresponding vertical support rods 4. The arc-shaped outer mold 2 and the arc-shaped inner mold 1 are locked by setting locking screws 6 on the locking holes of the corresponding vertical support rods 4. The locking screws 6 are fastened by bolts.

[0021] In this embodiment, the positioning mechanism is a concave-convex water-stop positioning mechanism, that is, several groove structures are evenly arranged on the arc-shaped inner mold 1, and several boss structures are evenly arranged on the side where the end mold 3 is connected to the arc-shaped inner mold 1. The end mold 3 contacts the arc-shaped inner mold 1 by rotating, and is positioned and locked by the corresponding groove structure and boss structure, so as to achieve sealing of both sides of the grouting template. The shape of the groove structure and the boss structure can be selected as trapezoidal or other shapes, which reduces the safety hazard of misalignment during the splicing construction process.

[0022] In this embodiment, the cast product needs to have arc-shaped connecting holes for interconnection. Furthermore, several mounting holes 7 are vertically and evenly provided on the arc-shaped inner mold 1, and several bolt holes are provided on the corresponding end mold 3 on the same horizontal plane. Arc-shaped connecting holes are pre-drilled using a mandrel. One end of the mandrel is positioned and fixed within the mounting hole 7, and the other end is detachably fixed to the bolt hole using bolts. A positioning hook is provided on the mounting hole 7, and a positioning rod is provided on one end of the mandrel. The positioning rod engages with the positioning hook to complete the positioning of the mandrel, and the other end passes directly through the bolt hole and is fastened with bolts.

[0023] In this embodiment, the cast product also needs to have ventilation holes 8. Correspondingly, ventilation holes 8 are provided at the corresponding positions of the arc-shaped inner mold 1 and the arc-shaped outer mold 2. The two ventilation holes 8 are sealed by a flexible plate, preferably a bendable polyurethane plate with sufficient rigidity. The polyurethane plate is fastened and compacted by two turnbuckles in a cross shape. The two ends of the turnbuckles are provided with arc plates that fit the arc shape. When providing support force, the arc plates can fit with the bent polyurethane plate, improve stability, and prevent the polyurethane plate from slipping under force during the casting process.

[0024] In this embodiment, inclined supports 9 are provided on the outer sides of the arc-shaped outer mold 2 and the arc-shaped inner mold 1. The other end of the inclined supports 9 is detachably connected to the track frame 13, further forming a triangular support to improve the stability of the pouring process after molding. Ladders 11 are provided on the vertical support rod 4 and the horizontal support rod 5. An operating platform 12 is provided at the top of the ladder 11. A feeding hopper 10 is provided at the top of the arc-shaped outer mold 2. Operators can climb the ladder 11 to the operating platform 12 at the top and pour concrete into the feeding hopper 10.

[0025] In this embodiment, vibrators are installed on the outer sides of the arc-shaped outer mold 2 and the arc-shaped inner mold 1 at the upper, middle and lower positions respectively. After the lower layer of concrete is poured, the lower layer vibrator is used to vibrate and remove air bubbles; then the middle layer of concrete is poured, and the middle layer vibrator is used to vibrate and remove air bubbles; finally, the upper layer of concrete is poured, and the upper layer vibrator is used to vibrate and remove air bubbles. Finally, the upper surface is manually ground smooth. Because the area is small, manual operation can ensure the flatness of the upper surface.

[0026] The process of completing product casting using this utility model: Model erection: First, fix and level the walking track on the ground. Install the outer and inner mold walking frames onto the arc-shaped outer mold 2 and arc-shaped inner mold 1 respectively, and install the ladder 11 and operating platform 12. All the above installations can be detached by using pre-set threaded holes and threaded fastening structures. Use a gantry crane to hoist the arc-shaped outer mold 2 as a whole onto the walking track, and then hoist and install the pre-embedded steel cage and junction box. Hoist and install the arc-shaped inner mold 1 end mold 3 as a whole and slide it to the bottom mold to start the overall model assembly. After the model is assembled, fix the walking wheels at the bottom of the model by locking screws 6 at the top and bottom of the vertical support rod 4, and connect the diagonal support 9 to the track frame 13 to ensure the overall stability of the vertical model. Install the bent mandrel. Finally, use a fan-shaped polyurethane board to seal the skylight hole and tighten it tightly with two turnbuckles with arc plates. The preparatory work for pouring is completed.

[0027] During pouring: According to the progress of concrete layer pouring, the attached vibrators at the bottom, middle and top of the formwork can be turned on in sequence to assist in the vibration of the concrete and promote the expulsion of air bubbles inside the concrete.

[0028] After the casting is completed, the curved component is naturally cured. When demolding, first use steel wire rope to connect and tighten the product hoisting bolts to the gantry crane, then remove the locking screw 6, loosen the diagonal support 9, unlock the traveling wheel, remove the bent mandrel, and use the jack demolding device to open the molds on both sides 3 and the inner curved mold 1, and the outer curved mold 2 and the inner curved mold 1. Finally, the product is hoisted to the storage yard.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
