Description

Technical Field

[0001] The utility model relates to the technical field of post-casting strip construction, in particular to a pre-buried template structure. Background Art

[0002] During the main construction phase of large-scale projects, due to factors such as the need to set up post-casting strips, install engineering pipe well post-casting slabs, and uncertainties in the early design, it is necessary to reserve areas for post-casting. Casting can only be completed after the later installation of supporting pipelines, equipment, and decorative renovations. The space for setting up support frames, making formwork, and pouring concrete is limited, making construction very difficult. Pre-buried formwork is now used. Pre-buried formwork can meet all the needs of post-construction work such as hole drilling and shaping. Concrete can be poured directly without the need to set up formwork support frames and re-make formwork. This simplifies construction, saves time and costs, and ensures project quality.

[0003] Patent CN109944278A discloses a post-cast strip support-free structure and a post-cast strip construction method, which is to set embedded parts to produce embedded holes, and then align the through holes of the bottom template with the embedded holes, and insert bolts, which is equivalent to using bolts to fix the bottom template below the reserved holes. During the construction process, the template must be set after the concrete is poured first, that is, the concrete layer must be poured first and then the bottom template can be fixed with bolts. When encountering a hole with inconvenient space construction, the setting of the bottom template is very inconvenient.

[0004] Therefore, a formwork that can be relatively fixed before pouring concrete is needed to simplify the construction process and provide convenience for construction. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The purpose of the utility model is to provide a pre-buried formwork structure to solve the problems existing in the prior art, so that the post-casting parts do not need secondary formwork, and can be set up before pouring concrete, providing convenience for construction and being adaptable to various post-casting parts.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1-Figure 2 As shown, the utility model provides a pre-embedded formwork structure, including a concrete retaining plate 4, an embedded support member 1, a plate 3 and a fixing member 2. The concrete retaining plate 4 is used to be arranged around the periphery of the reserved hole to block the concrete; the plate 3 is used to be laid at the bottom of the reserved hole and fully paved the reserved hole. The embedded support member 1 is arranged below the plate 3 to support the plate 3, and the fixing member 2 is arranged at the lower part of the plate 3 to reinforce the plate 3.

[0027] In this embodiment, the embedded formwork structure also includes a support member 5, and a plurality of support members 5 can be arranged side by side, and the two ends of the support member 5 are respectively abutted against the retaining concrete plates 4 opposite on both sides to support the retaining concrete plates 4. The arrangement of the support member 5 ensures that when pouring concrete around the reserved hole, the retaining concrete plates 4 will not move closer to the middle, ensuring that the form of the reserved hole does not change. It should be noted that the shape of the retaining concrete plates 4 will also be appropriately changed according to the different shapes of the reserved holes, and the support member 5 can also be appropriately changed. For example, if it is a square reserved hole, the retaining concrete plates 4 are set to multiple pieces to form a square structure, and the support member 5 is against the two opposite retaining concrete plates 4. If it is a circular reserved hole, the retaining concrete plates 4 can be set to a cylindrical retaining concrete plate 4. At this time, the support member 5 is against the diameter direction of the cylindrical retaining concrete plate 4. The retaining concrete plates 4 of the circular reserved hole can also be provided with two arc plates on both sides, and the support member 5 is against the two arc plates.

[0028] It should be noted that holes can be opened on the retaining concrete plate 4 as needed to allow steel bars to pass through or to serve as holes for other purposes.

[0029] In this embodiment, the embedded support member 1 is an embedded steel structure, which has great stability and can fully support the plate 3. It should be noted that other types of embedded support members 1 can also be used, as long as they can fully support the plate 3 and ensure the stability of the plate 3, such as using a concrete structure or a mixed structure.

[0030] In this embodiment, the embedded steel structure is an embedded angle steel. The steel angle of the embedded angle steel is used to be fixedly connected to the steel bar to fix the position of the embedded angle steel. The embedded angle steel is bundled together with the already erected structural steel bar to ensure the position of the embedded angle steel, so that the laying of the plate 3 is more stable. It should be noted that other types of embedded steel structures can also be used, as long as they can support the plate 3 and ensure that the position is relatively fixed, such as using T-shaped steel.

[0031] In this embodiment, multiple groups of embedded angle steels are provided, and any group includes two embedded angle steels. The two embedded angle steels in the same group are relatively arranged on both sides of the plate 3. It should be noted that different groups of embedded angle steels can be set according to the shape of the reserved hole. For example, a square-shaped reserved hole can have embedded angle steels on all four sides or only on the two long sides, as long as it can support the plate 3. A circular reserved hole can have multiple groups of embedded angle steels, and the two embedded angle steels in one group are relatively arranged along the diameter direction of the reserved hole.

[0032] In this embodiment, the plate 3 is a steel plate, which has low cost and stable structure. It should be noted that other types of plate 3, such as iron plate, etc., can also be used.

[0033] It should also be noted that the laying of the steel plate needs to strictly follow the requirements of the design drawings, adjust the mortar surface of the steel plate and the structural position or elevation of the later pouring, and if there are other needs on the plate 3, holes can be opened without affecting the later pouring.

[0034] In this embodiment, the fixing part 2 includes a reinforcing rod, which is arranged under the plate 3, and the two ends of the reinforcing rod are detachably connected to the two embedded angle steels of the same group. The embedded angle steel is provided with a reinforcing hole 6, and the two ends of the reinforcing rod are provided with a bending portion, which is used to insert the reinforcing hole 6. The reinforcing rod prevents the plate 3 from collapsing when pouring concrete, and the reinforcing rod can be removed or not according to the installation space.

[0035] In this embodiment, there are multiple reinforcement rods and reinforcement holes 6, and the number of reinforcement rods is not greater than the number of reinforcement holes 6. The number of reinforcement rods and the intervals between them can be determined according to the specific situation, as long as it can ensure that the plate 3 will not collapse when the concrete is poured later.

[0036] Specifically, the process of embedded formwork structure is divided into the following two types:

[0037] If there is space to install reinforcement rods in the later stage: design the embedded angle steel structure → effectively fix the embedded angle steel to the structure to be poured once → set the top elevation of the steel plate as the bottom elevation of the floor slab → set 4 retaining concrete plates around the post-pouring part → tie the plate reinforcement → check the elevation and position before pouring the post-pouring part → set up detachable reinforcement rods → pour concrete → remove the reinforcement rods and cut off the exposed parts.

[0038] There is no space to install reinforcement rods in the later stage: design the embedded angle steel structure → effectively fix the embedded angle steel to the structure to be poured once → set the top elevation of the steel plate to the bottom elevation of the floor slab → install detachable reinforcement rods → set 4 retaining concrete plates around the post-pouring parts → tie the plate reinforcement → check the elevation and position before pouring the post-pouring parts → pour concrete construction.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
