Description

Technical Field

[0001] This utility model relates to the field of hollow floor slab core molds, and in particular to a thick sheet vacuum forming core mold for hollow floor slabs with pad blocks. Background Technology

[0002] Hollow core slab core molds are widely used components in the construction industry to form the internal space of hollow core slabs, thereby improving the load-bearing capacity and sound insulation of the floor slab. Traditional core molds are manufactured by blow molding, and the blow-molded core molds are integral structures. Therefore, they need to be stacked together for transportation, which greatly wastes space. At the same time, in order to fix the floating steel bars, ordinary hollow core slab core molds have grooves designed on the surface of the core mold. Due to the design of the grooves, the amount of concrete used will increase. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a hollow floor slab thick sheet vacuum forming core mold with an internal support structure that reduces the amount of concrete used by reducing the concave structure design on the core mold surface.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a hollow floor slab thick sheet vacuum forming core mold with pad blocks, including an upper core mold and a lower core mold formed by thick sheet vacuum forming method. The upper core mold includes an upper core mold body, and a first cavity is provided in the upper core mold body. The lower core mold includes a lower core mold body, and a second cavity is provided in the lower core mold body. The upper core mold and the lower core mold are connected by a connector. When the upper core mold body and the lower core mold body are closed, the first cavity and the second cavity are combined to form an internal cavity.

[0005] Both ends of the surfaces of the upper core mold body and the lower core mold body are provided with a first protruding pad and a second protruding pad, and a gap is provided between the first protruding pad and the second protruding pad for placing and fixing anti-buoyancy steel bars.

[0006] Furthermore, the gap between the first and second raised pads at both ends of the upper core mold body surface is aligned.

[0007] The gap between the first and second raised pads at both ends of the lower core mold body surface is aligned.

[0008] Furthermore, the first and second raised pads have a third cavity structure inside, which is connected to the cavity inside the mold.

[0009] Furthermore, both the first and second protrusions have an uneven surface structure.

[0010] Furthermore, multiple third protrusions are provided in the middle of the surfaces of both the upper and lower core mold bodies.

[0011] Furthermore, multiple third protrusions are symmetrically arranged in pairs along the centerline of the upper or lower core mold body surface.

[0012] Furthermore, the gap is located at the center line of the upper core mold body surface or the lower core mold body surface.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this structure, the design of the first and second raised pads allows the gap between the first and second raised pads to replace the original groove design, thereby reducing the amount of concrete used and lowering the construction cost.

[0015] 2. The gap between the first and second raised pads is aligned to make the placement of the anti-buoyancy steel bars more stable and improve the load-bearing capacity of the floor slab.

[0016] 3. The third cavity structure inside the first and second raised pads is connected to the cavity inside the mold, which further reduces the weight of the core mold and facilitates handling and construction.

[0017] 4. By using thick sheet vacuum forming for the upper and lower core molds, the core molds can save more space during handling, thereby improving transportation efficiency. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the internal structure of a hollow floor slab thick sheet vacuum forming core mold with pad blocks, according to an embodiment of this application.

[0020] The diagram is labeled as follows: upper core mold 1, lower core mold 2, inner cavity 3, first raised pad 4, second raised pad 5, gap 6, third cavity structure 7, and third raised block 8. Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1As shown, an embodiment of this application discloses a thick sheet vacuum forming core mold for a hollow floor slab with pad blocks, including an upper core mold 1 and a lower core mold 2 formed by thick sheet vacuum forming. The upper core mold 1 includes an upper core mold 1 body, and a first cavity is provided inside the upper core mold 1 body. The lower core mold 2 includes a lower core mold 2 body, and a second cavity is provided inside the lower core mold 2 body. The upper core mold 1 and the lower core mold 2 are connected by a connector. When the upper core mold 1 body and the lower core mold 2 body are closed, the first cavity and the second cavity are combined to form an internal cavity 3.

[0023] Both ends of the surface of the upper core mold 1 and the lower core mold 2 are provided with a first protruding pad 4 and a second protruding pad 5, and a gap 6 is provided between the first protruding pad 4 and the second protruding pad 5 for placing and fixing anti-buoyancy steel bars.

[0024] In practical use, the anti-buoyancy steel bars are inserted into the gap 6 formed by the first protruding pad 4 and the second protruding pad 5 at both ends of the core mold body. The first protruding pad 4 and the second protruding pad 5 limit the anti-buoyancy steel bars. The surfaces of the first pad and the second pad are used to support the panel reinforcement. Then, concrete is poured. After the concrete sets, a hollow core floor structure is formed.

[0025] In this structure, the first protruding pad 4 and the second protrusion not only support the panel reinforcement, but the gap formed between them also acts as a limit to the floating reinforcement, thus reducing the need for grooves on the core mold body, thereby reducing the amount of concrete used and lowering construction costs. Furthermore, the design of the first protruding pad 4 and the second protruding pad 5 enhances the structural strength of the core mold and improves its durability.

[0026] Meanwhile, due to the use of thick-sheet vacuum forming, multiple upper core molds 1 and multiple lower core molds 2 can be stacked together during transportation, greatly reducing the wasted space in the central cavity of the finished core mold and improving the space utilization rate of the core mold during transportation. Furthermore, the use of thick-sheet vacuum forming makes the overall structure of the core mold lighter and easier to install.

[0027] In this embodiment, the gap 6 between the first protruding pad 4 and the second protruding pad 5 at both ends of the surface of the upper core mold 1 is aligned; the gap 6 between the first protruding pad 4 and the second protruding pad 5 at both ends of the surface of the lower core mold 2 is also aligned.

[0028] Specifically, the design of the first raised pad 4 and the second raised pad 5 allows the width of the gap 6 between them to be adjusted according to the diameter of the anti-buoyancy steel bars actually used, thereby ensuring that the anti-buoyancy steel bars can be stably locked in and are not prone to displacement or falling off. In addition, this method of aligning the gap 6 allows the anti-buoyancy steel bars to be horizontally locked onto multiple core molds, ensuring the overall stability of the hollow core floor structure.

[0029] In this embodiment, the first raised pad 4 and the second raised pad 5 have a third cavity structure 7 inside, and the third cavity structure 7 is connected to the cavity 3 inside the mold.

[0030] Specifically, the third cavity structure 7 inside the first raised pad 4 and the second raised pad 5 not only reduces the overall weight of the core mold, but also allows multiple upper core molds 1 to be stacked together and multiple lower core molds 2 to be stacked together during transportation. When stacking, the stacking gap 6 of multiple upper core molds 1 and multiple lower core molds 2 can be reduced. For example, the first raised pad 4 and the second raised pad 5 of the next upper core mold 1 can extend into the third cavity structure 7 of the previous upper core mold 1.

[0031] In this embodiment, both the first protrusion and the second protrusion have concave-convex surfaces.

[0032] Specifically, this concave-convex structure design increases the friction between the first raised pad 4 and the second raised pad 5 and the concrete, making the core mold more stable during concrete pouring, thus ensuring the accuracy and stability of the hollow core floor structure. At the same time, this concave-convex structure also increases the surface roughness of the core mold, improving the adhesion between the core mold and the concrete, further enhancing the overall strength of the hollow core floor structure.

[0033] In this embodiment, multiple third protrusions 8 are provided in the middle of the surface of both the upper core mold 1 body and the lower core mold 2 body.

[0034] Specifically, the design of these third protrusions 8 is mainly to provide more support points for the core mold supporting the panel reinforcement, thereby increasing the contact area between the core mold and the panel reinforcement and improving the overall stability and load-bearing capacity of the hollow core floor structure.

[0035] In this embodiment, multiple third protrusions 8 are symmetrically arranged in pairs along the centerline of the upper core mold 1 body surface or the lower core mold 2 body surface.

[0036] Specifically, this symmetrical arrangement makes the core mold more evenly stressed when supporting the panel reinforcement, avoiding structural deformation or damage caused by uneven stress, and further improving the stability and durability of the hollow core floor structure.

[0037] In this embodiment, the gap 6 is located at the center line of the upper core mold 1 body surface or the lower core mold 2 body surface.

[0038] Specifically, this design allows the anti-buoyancy reinforcement bars to be more accurately attached to the core mold, ensuring the accuracy and stability of the hollow core floor structure. At the same time, it allows the core mold to bear load more evenly.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
