Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pouring technology, and in particular to a concrete pouring device. Background Technology
[0002] For most secondary structures, since the pouring surface is directly above, concrete can be poured directly from top to bottom using a top-mounted pump pipe or hopper. However, for side-groove secondary structures, since there is no opening at the top, concrete can only be poured in from the side, posing a construction challenge. Current technology for side-groove secondary structures typically involves installing wooden formwork with an opening at the top. The wooden boards are cut and assembled into a sloping bucket shape, creating an opening at the top for direct top-down concrete pouring using a top-mounted pump pipe or hopper. However, after demolding, concrete blocks protruding from the wall surface appear at the sloping bucket location, requiring manual chiseling and grinding to smooth them out. Furthermore, cutting and assembling the wooden formwork into the sloping bucket takes time, impacting the construction efficiency of side-groove secondary structures. Utility Model Content
[0003] The purpose of this invention is to provide a concrete pouring device to alleviate the problems in the prior art where concrete blocks appear at the position of the inclined bucket after demolding, requiring manual chiseling and grinding to smooth them out; and the impact of cutting and assembling wooden formwork into an inclined bucket on construction efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0005] A concrete pouring device includes: a template and a hopper device, the hopper device being slidably installed on the template, the template being provided with a feeding structure, and the hopper device being able to slide along the length direction of the template to open or close the feeding structure.
[0006] Furthermore, the hopper device includes an inclined hopper and a baffle. The baffle is connected to the side of the inclined hopper, and the inclined hopper is slidably connected to the template. The baffle can open or close the feeding structure during movement along the length of the template.
[0007] Furthermore, the top of the inclined hopper is provided with a discharge port, and the cross-sectional area of the inclined hopper gradually decreases from top to bottom.
[0008] Furthermore, the side of the inclined hopper facing the template is configured as an open structure.
[0009] Furthermore, the template is provided with a guide rail assembly along its length, and the inclined hopper is provided with a slider assembly, the slider assembly slidingly engaging with the guide rail assembly.
[0010] Furthermore, the guide rail assembly includes a first guide rail and a second guide rail, the first guide rail and the second guide rail are arranged in parallel and spaced apart, and the feeding structure is disposed between the first guide rail and the second guide rail;
[0011] The slider assembly includes a top slider and a bottom slider. The top slider is disposed at the top of the inclined hopper, and the bottom slider is disposed at the bottom of the inclined hopper. The top slider is slidably engaged with the first guide rail, and the bottom slider is slidably engaged with the second guide rail.
[0012] Furthermore, the feeding structure includes a feeding port, which is disposed between the first guide rail and the second guide rail.
[0013] Furthermore, the area of the baffle is larger than the area of the feed inlet.
[0014] Furthermore, the template is provided with a connection structure along its circumference for connecting with a standard planar steel template.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other. Figure 1 This is a structural schematic diagram of the concrete pouring device provided in an embodiment of the present invention.
[0031] Example 1
[0032] In existing technology, the conventional method for installing side-groove secondary structures involves using wooden planks for the formwork. An opening is pre-drilled at the top, and the planks are cut and assembled into a sloping bucket shape, forming an opening directly at the top. This allows concrete to be poured directly from above using a top-mounted pump pipe or hopper. However, after demolding, concrete blocks protruding from the wall surface appear at the location of the sloping bucket, requiring manual chiseling and grinding to smooth them out. Furthermore, cutting and assembling the wooden formwork into the sloping bucket requires a certain amount of time, affecting the construction efficiency of the side-groove secondary structure.
[0033] In view of this, the present utility model provides a concrete pouring device, including: a template 100 and a hopper device 200, the hopper device 200 being slidably installed on the template 100, the template 100 being provided with a feeding structure, and the hopper device 200 being able to slide along the length direction of the template 100 to open or close the feeding structure.
[0034] The hopper device 200 can slide back and forth along the length of the formwork 100. After the concrete pouring device is installed and reinforced, the hopper device 200 is moved to face the inlet structure, opening the inlet structure and pouring concrete into the hopper device 200 through a pump pipe or other means. After the concrete is filled and compacted, the sliding hopper device 200 moves to the position covering the inlet structure, closing it and completing the pouring. By moving the hopper device 200 to cover the inlet structure after pouring, an effective planar seal is formed, ensuring a smooth concrete appearance at the pouring opening. This avoids the problem of three-dimensional triangular concrete protrusions that would occur after the wooden formwork 100 is removed after pouring, requiring subsequent chiseling and grinding, effectively improving the concrete appearance quality and increasing construction efficiency.
[0035] The concrete pouring device is low in manufacturing cost, simple in structure, reusable, and can be reused multiple times. Compared to the single-use nature of wooden formwork 100, it reduces construction costs. The concrete pouring device is a sturdy, integral component, avoiding the risks of safety and quality accidents such as formwork bursting during pouring due to inconsistent on-site assembly levels of wooden formwork 100.
[0036] In an optional embodiment, the hopper device 200 includes an inclined hopper 210 and a baffle 220. The baffle 220 is connected to the side of the inclined hopper 210. The inclined hopper 210 is slidably connected to the template 100. The baffle 220 can open or close the feeding structure during the movement along the length direction of the template 100.
[0037] Please see Figure 1 The inclined hopper 210 and the baffle 220 are an integral structure, with the baffle 220 connected to the right side of the inclined hopper 210. As the inclined hopper 210 slides along the length of the formwork 100, the position of the baffle 220 also changes. When concrete needs to be poured, simply move the inclined hopper 210 to the feeding structure directly opposite the formwork 100, and concrete can be poured into the inclined hopper 210 through a pump pipe or other means, then flow out through the feeding structure. After the concrete is filled and compacted, slide the inclined hopper 210 so that the baffle 220 covers the feeding structure, thus sealing the feeding structure and completing the pouring process.
[0038] In an optional embodiment, the top of the inclined hopper 210 is provided with a discharge port, and the cross-sectional area of the inclined hopper 210 gradually decreases from top to bottom.
[0039] Concrete enters the inner cavity of the inclined hopper 210 through the discharge port. Since the cross-sectional area of the inclined hopper 210 gradually decreases from top to bottom, the concrete can be poured through the feeding structure at a relatively fast speed in the inclined hopper 210, which improves the pouring efficiency.
[0040] In an optional embodiment, the side of the inclined hopper 210 facing the template 100 is configured as an open structure.
[0041] This configuration allows concrete to flow outward sequentially through the inclined hopper 210 and the feeding structure when the inclined hopper 210 moves to the feeding structure directly opposite the template 100, thus achieving pouring.
[0042] In an optional embodiment, the template 100 is provided with a guide rail assembly 300 along its length, and the inclined hopper 210 is provided with a slider assembly 400, which slides in cooperation with the guide rail assembly 300.
[0043] Please see Figure 1 The guide rail assembly 300 includes a first guide rail 310 and a second guide rail 320, which are arranged in parallel and spaced apart. The feeding structure is disposed between the first guide rail 310 and the second guide rail 320. The slider assembly 400 includes a top slider and a bottom slider. The top slider is disposed at the top of the inclined hopper 210, and the bottom slider is disposed at the bottom of the inclined hopper 210. The top slider is slidably engaged with the first guide rail 310, and the bottom slider is slidably engaged with the second guide rail 320.
[0044] The inclined hopper 210 slides along the first guide rail 310 and the second guide rail 320 via the top slider and the bottom slider. The feeding structure is located in the middle between the first guide rail 310 and the second guide rail 320, so that the inclined hopper 210 can face the feeding structure directly. The baffle 220 can block the feeding structure.
[0045] In an optional embodiment, the feeding structure includes a feeding port 500, which is disposed between the first guide rail 310 and the second guide rail 320.
[0046] It should be noted that the area of the baffle 220 is larger than the area of the feed inlet 500. That is, the length of the baffle 220 is greater than the length of the feed inlet 500, and the width of the baffle 220 is greater than the width of the feed inlet 500, so that the baffle 220 can completely block the feed inlet 500.
[0047] In an optional embodiment, the template 100 is provided with a connection structure along the circumference for connecting with a standard planar steel template.
[0048] Specifically, the connection structure includes a plurality of template connection bolt holes 600 evenly arranged along the circumference of the template 100.
[0049] Please see Figure 1 During installation, the concrete pouring device can be spliced with standard flat steel formwork through the 600mm bolt holes in the formwork connection. It offers high installation efficiency, can be bolted to standard flat steel formwork, and is suitable for most construction scenarios, effectively reducing the time required for cutting and assembling conventional wooden formwork.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
