[0001] This invention relates to the field of civil engineering technology, and more specifically, to a device and construction method for embedding a concrete slab on one side. Background Technology

[0002] With urban development, integrated utility tunnels and other facilities have been improved, often running parallel to or intersecting with underground pipelines. During construction, these tunnels may collide with underground pipelines, necessitating modifications to the existing pipelines. However, when encountering main urban pipelines, major alterations are not feasible; only minor modifications are possible. For example, if an integrated utility tunnel is located above a sewage pipe and collides with its manhole, lowering the manhole's clearance below the tunnel and sealing it as a concealed manhole would resolve the collision issue. However, sealing the manhole in a confined space with limited sewage flow and construction space presents a significant challenge. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Device Example:

[0033] See Figures 1 to 13The figure shows a preferred structure of the device for embedding a concrete slab on one side in this embodiment. As shown, the device for embedding a concrete slab on one side includes: two templates 1, multiple connectors 2, and a concrete injection mechanism 3. The two templates 1 are arranged side-by-side, with a preset distance between them. This preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on it. Specifically, the two templates 1 have the same structure, size, and shape. Each template 1 can be a steel mold, a wooden mold, or its shape can be determined according to the shape of the opening to be installed by the device for embedding the concrete slab on one side. Specifically, it can be a rectangular plate, a circular plate, or other shapes; this embodiment does not impose any restrictions on it. The thickness of each template 1 can be calculated, and a conventional 15mm thick template can be used.

[0034] The concrete injection mechanism 3 is positioned between the two templates 1. The concrete injection mechanism 3 is used to position the two templates 1 so that the two templates 1 maintain the preset distance. The concrete injection mechanism 3 injects concrete between the two templates 1, so that the two templates 1 are connected together by the concrete.

[0035] Each connector 2 is connected to two templates 1. Specifically, the connectors 2 are spaced apart on the templates 1, preferably evenly distributed. Each connector 2 is a water-stop tie bolt. The arrangement of the connectors 2 on the templates 1 is determined according to the thickness and area of ​​the concrete slab; this embodiment does not impose any restrictions on this.

[0036] As can be seen, in this embodiment, the concrete injection mechanism 3 is set between two parallel templates 1 to position the two templates 1 and inject concrete between them. Each connector 2 is connected to both templates 1, thereby connecting the two templates 1 and the concrete together. In this way, by placing the device in the opening to be installed, injecting concrete between the two templates 1, and curing the concrete, the construction of the embedded concrete slab can be completed. This allows for construction from one side in a narrow space, solving the problem of not being able to close the construction space in the prior art. The device has a simple structure and is easy to implement.

[0037] See Figures 1 to 7 The concrete injection mechanism 3 includes: an injection pipe 31, two formwork fixing components 32, and a vibration structure. One end of the injection pipe 31 is closed, and the other end is open. The open end of the injection pipe 31 ( Figure 1 The upper end shown is the concrete injection port, used to receive concrete. The injection pipe 31 can be made of metal.

[0038] Two template fixing components 32 are spaced apart on the injection tube 31, specifically along the height direction of the injection tube 31. Figure 1The template fixing components are spaced out from top to bottom as shown. Each template fixing component 32 corresponds to one of the two templates 1, and each template fixing component 32 is used to position the corresponding template 1.

[0039] Preferably, each template fixing assembly 32 includes two clamping plates 321. The two clamping plates 321 are arranged side-by-side, both passing through the injection tube 31, and both clamping plates 321 are connected to the injection tube 31, thus fixing the two clamping plates 321 relative to the injection tube 31. Specifically, each clamping plate 321 has a through hole corresponding to the injection tube 31, through which the injection tube 31 passes, and the injection tube 31 is fixedly connected to the clamping plate 321, thus connecting the clamping plate 321 to the injection tube 31. In practical implementation, each clamping plate 321 can be rectangular, circular, or other shapes according to actual working conditions, and the dimensions of each clamping plate 321 can be adjusted and processed according to actual needs.

[0040] Each template 1 has a through hole 11 at the corresponding injection tube 31. The through hole 11 is used for the injection tube 31 to pass through. Each template 1 passes through the through hole 11 and is inserted into the injection tube 31. Furthermore, each template 1 is clamped between two clamping plates 321 in the corresponding template fixing assembly 32.

[0041] The injection pipe 31 is positioned between two template fixing components 32 and has multiple concrete output holes 311 spaced apart on its side wall. The concrete output holes 311 are evenly distributed along the circumference of the injection pipe 31 and are staggered on the injection pipe 31. Specifically, the opening of each concrete output hole 311 is more than twice the size of the concrete aggregate.

[0042] The vibration structure is set on the side wall of the injection pipe 31 between the two template fixing components 32. The vibration structure is used to vibrate the concrete between the two templates 1.

[0043] Preferably, the vibration structure includes a plurality of vibrating rods 33. Each vibrating rod 33 is spaced apart along the circumferential direction of the injection pipe 31 on the side wall of the injection pipe 31, and each vibrating rod 33 is detachably connected to the side wall of the injection pipe 31. Specifically, the side wall of the injection pipe 31 has a threaded hole corresponding to each vibrating rod 33, and one end of each vibrating rod 33 is threaded, with this end screwed into the threaded hole to achieve relative fixation between the vibrating rod 33 and the injection pipe 31.

[0044] More preferably, each vibrating rod 33 is evenly distributed along the circumference of the injection pipe 31. Each vibrating rod 33 is placed at the same height in the injection pipe 31 and is placed above each concrete output hole 311.

[0045] When the concrete between the two templates 1 is vibrated, the injection pipe 31 is connected to the professional vibration equipment. The professional vibration equipment vibrates the injection pipe 31, and the vibration is transmitted to each vibrating rod 33 through the injection pipe 31. Each vibrating rod 33 vibrates the concrete.

[0046] In this embodiment, there are four vibrating rods 33. The length of each vibrating rod 33 can be determined according to the actual situation. This embodiment does not impose any restrictions on this.

[0047] See Figures 1 to 7 The injection pipe 31 includes a closed section 312, an intermediate section 313, and an injection section 314. The closed section 312, the intermediate section 313, and the injection section 314 are detachably connected in sequence. The closed section 312, the intermediate section 313, and the injection section 314 are all tubular and hollow inside to facilitate the transportation of concrete.

[0048] The first end of closed section 312 ( Figure 6 The end face of the lower end shown is connected to one of the clamps 321 in one of the template fixing components 32, and the other clamp 321 is sleeved on the first end of the middle section 313. Figure 6 The lower end shown). Specifically, the end face of the first end of the closed section 312 is in a closed state, and the second end of the closed section 312 ( Figure 6 The upper end shown is open, with one of the clamping plates 321 fixedly connected to the end face of the first end of the closed section 312. The closed section 312 has a certain height, which can be determined according to the thickness of the template 1; this embodiment does not impose any limitations on this. The second end of the closed section 312 is detachably connected to the first end of the intermediate section 313, which passes through a through hole in another clamping plate 321, and this clamping plate 321 is connected to the first end of the intermediate section 313.

[0049] Preferably, the inner wall of the second end of the closed section 312 is provided with threads, and the first end of the intermediate section 313 is provided with a first receiving threaded tube 34 protruding towards the closed section 312. The interior of the first receiving threaded tube 34 is connected to the interior of the intermediate section 313, and the first receiving threaded tube 34 is screwed to the second end of the closed section 312 to realize the detachable connection between the closed section 312 and the intermediate section 313.

[0050] Middle section 313 near the second end ( Figure 6 One of the clamps 321 from another template fixing assembly 32 is fitted at the upper end shown, and the other clamp 321 is fitted at the first end of the injection section 314. Figure 6 The lower end shown), the second end of injection segment 314 ( Figure 6The upper end (shown) is used to receive concrete. Specifically, both ends of the intermediate section 313 and both ends of the injection section 314 are open. The intermediate section 313 passes through a through hole in one of the clamping plates 321 of another template fixing assembly 32 near its second end, and the intermediate section 313 is fixed relative to the clamping plate 321. However, there is a certain distance between the clamping plate 321 and the end face of the second end of the intermediate section 313. This distance can be determined according to the thickness of the template 1, and this embodiment does not impose any restrictions on it. The injection section 314 passes through a through hole in the other clamping plate 321, and the first end of the injection section 314 is fixed relative to the clamping plate 321.

[0051] Preferably, the inner wall of the second end of the intermediate section 313 is provided with threads, and the first end of the injection section 314 is provided with a second receiving threaded tube 35. The interior of the second receiving threaded tube 35 is connected to the interior of the injection section 314. The second receiving threaded tube 35 is screwed to the second end of the intermediate section 313 to realize the detachable connection between the intermediate section 313 and the injection section 314.

[0052] Each concrete output hole 311 and the vibrating structure are set on the side wall of the intermediate section 313. Specifically, each concrete output hole 311 is evenly opened on the side wall of the intermediate section 313, and each vibrating rod 33 is set on the side wall of the intermediate section 313 along the circumferential direction of the intermediate section 313 and placed above each concrete output hole 311.

[0053] Preferably, each concrete output hole 311 is along the height direction of the middle section 313 ( Figure 6 The concrete output holes 311 are staggered in the direction shown from top to bottom. Specifically, each concrete output hole 311 is set in at least two rows, with each row arranged vertically along the height of the middle section 313. The concrete output holes 311 in each row are evenly distributed along the circumference of the middle section 313, and the concrete output holes 311 in the upper and lower rows are staggered.

[0054] In this embodiment, there are four concrete output holes 311, arranged in two rows. Two concrete output holes 311 in each row are symmetrically arranged, and the concrete output holes 311 in the upper and lower rows are staggered.

[0055] As can be seen, in this embodiment, the concrete injection mechanism 3 has a simple structure and is easy to implement.

[0056] See Figure 1 , Figures 8 to 10In the above embodiments, each template 1 has a plastic strip 4 near its edge on the side facing the other template 1. This plastic strip 4 is annular. Specifically, plastic strips 4 are provided on the opposing surfaces of both templates 1, with each plastic strip 4 located near its edge. The annular shape of the plastic strip 4 can match the shape of the template 1; when the template 1 is circular, the plastic strip 4 is annular, and when the template 1 is rectangular, the plastic strip 4 is rectangular. Preferably, the plastic strip 4 is bonded to the template 1 using adhesive.

[0057] The ends of the plastic strip 4 are inclined outwards; specifically, the first end of the plastic strip 4 ( Figure 8 The upper end shown is connected to the template 1, the plastic strip 4 is in an inclined state, and the second end of the plastic strip 4 ( Figure 8 The lower end (as shown) slopes outward, that is, the second end of the plastic strip 4 extends away from the center of the template 1 and toward another template 1.

[0058] Each template 1 has a through hole 11 at its center for the injection pipe 31 to pass through, and an opening 12 is provided at the position of each water-stop tie bolt to facilitate the passage of the water-stop tie bolt. Preferably, the openings 12 are evenly distributed in a circular shape with the through hole 11 as the center.

[0059] In this embodiment, there are four openings 12, and correspondingly, there are also four water-stop tie bolts.

[0060] As can be seen, in this embodiment, plastic strips 4 that slope outward are provided on the opposite surfaces of the two templates 1. After the concrete is filled between the two templates 1, the concrete spreads to the two sides of the template 1. The plastic strips 4 on each template 1 block the concrete and prevent it from seeping out along the gap between the template 1 and the side wall of the opening to be installed after the concrete is poured, thereby improving the concrete pouring effect.

[0061] In practice, depending on actual needs, reinforced concrete bars can be tied between the two formwork panels 1, thus forming reinforced concrete after the concrete is poured between the two formwork panels 1. Of course, depending on actual needs, only concrete can be poured between the two formwork panels 1.

[0062] In summary, in this embodiment, the concrete injection mechanism 3 is positioned between two parallel templates 1 to position the two templates 1 and inject concrete between them. Each connector 2 is connected to both templates 1, thereby connecting the two templates 1 and the concrete together. Thus, by placing the device in the opening to be installed, injecting concrete between the two templates 1, and curing the concrete, the construction of the embedded concrete slab can be completed. This allows for construction from one side in a confined space. The device has a simple structure and is easy to implement. Furthermore, the device can be manufactured in the factory, transported to the site for assembly, and then used for formwork support and concrete pouring in the opening to be installed, thereby improving the accuracy of construction operations.

[0063] Method Implementation Examples:

[0064] See Figure 14 This embodiment also proposes a construction method for unilaterally embedding concrete slabs using any of the above-mentioned devices for unilateral embedding of concrete slabs. The construction method includes the following steps:

[0065] Step S1: Place the device for embedding a concrete slab on one side into the opening to be installed and fix it in place.

[0066] Specifically, see Figures 1 to 13 The specific implementation process of the device for embedding a concrete slab on one side can be found in the above description, and will not be repeated here in this embodiment.

[0067] First, the device for embedding a concrete slab on one side is assembled. After assembly, the device is placed into the opening to be installed and fixed. Specifically, the device can be fixed by anchoring the injection pipe 31 to objects around the opening.

[0068] Step S2: Concrete is injected between the two templates through the concrete injection mechanism in the device for implementing the embedded concrete slab on one side.

[0069] Specifically, the injection device 5 injects concrete between the two templates 1 through the injection pipe 31, and delivers it into the interior of the template 1.

[0070] Step S3: After filling, vibrate the concrete between the two templates and cure it.

[0071] Specifically, after filling, the injection pipe 31 is vibrated using professional vibration equipment. The vibration is transmitted through the injection pipe 31 to each vibrator 33, which then vibrates the concrete between the two formwork panels 1. After curing to the preset strength as required, the injection pipe 31 is removed. The remaining parts can be removed depending on the actual situation.

[0072] As can be seen, in this embodiment, the device for embedding a concrete slab on one side is placed into the opening to be installed and fixed. Concrete is injected between the two templates through the concrete injection mechanism. Then, the concrete between the two templates is vibrated and cured to the preset strength. In this way, the concrete slab can be constructed from one side and can be applied to narrow spaces. This method is simple to operate and easy to implement.

[0073] It should be noted that the device and construction method for embedding a concrete slab on one side in this invention are based on the same principle, and related aspects can be referred to each other.

[0074] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0075] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0076] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
