Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a planar floor slab forming formwork and formwork components. Background Technology

[0002] Flat floor slab forming formwork is a type of mold used in construction engineering, mainly for cast-in-place floor slab construction. In existing technologies, formwork is generally erected on four sides on wooden molds or other rigid supports, requiring the construction of full-span scaffolding, which is time-consuming and labor-intensive. Our company has currently developed a construction method for formwork using hoisting, but the existing technology center lacks corresponding formwork that is easy to hoist. Utility Model Content

[0003] The problem solved by this utility model is that there is a lack of corresponding templates that are easy to hoist in the existing technology, and a planar floor slab forming template and template assembly are provided.

[0004] This utility model is achieved through the following technical solution: a planar floor slab forming template, the template including a top surface, the top surface being rectangular, and a set of downwardly extending side surfaces connected around the top surface, the side surfaces being perpendicular to the top surface, the top surface forming a cavity with the inner side of the enclosing side surface, the side surfaces having connecting holes horizontally arranged and extending from the cavity to the side surface, and the side surfaces having lifting grooves located on the side surfaces and extending through the bottom of the top and side surfaces, the lifting grooves being staggered from the connecting holes.

[0005] Furthermore, the number of connecting holes on a single template side can be one or more. When the number of connecting holes on a single template side is one, the connecting hole is located in the middle of the template side. When the number of connecting holes on a single template side is multiple, the connecting holes are symmetrically arranged along the length direction of the template side.

[0006] Furthermore, the template side with the connecting hole is located on two, three, or four adjacent template sides.

[0007] Furthermore, the number of lifting slots on a single template side can be one or more. When there is only one lifting slot on a single template side, the lifting slot is located in the middle of the template side. When there are multiple lifting slots on a single template side, the lifting slots are symmetrically arranged along the length of the template side.

[0008] Furthermore, the template side with the lifting groove can be a single template side or two opposing template sides.

[0009] Furthermore, the locations on the side of the template where the lifting groove can be provided include the middle and the edge of the side of the template.

[0010] Furthermore, the cross-section of the hoisting groove is half or a quarter of a regular shape. When the hoisting groove is located in the middle of the side of the template, the cross-section of the hoisting groove is half of a regular shape. When the hoisting groove is located at the edge of the side of the template, that is, when the hoisting groove is located at the four corners of the template, the cross-section of the hoisting groove is a quarter of a regular shape.

[0011] Furthermore, the cross-section of the hoisting groove is one of a semi-circle, a rectangle, or a half regular polygon.

[0012] Furthermore, the top surface and the interior of the sides of the template are provided with grid-like reinforcing ribs.

[0013] Another aspect of this utility model provides a planar floor slab forming template assembly, comprising several planar floor slab forming templates as described above, several templates arranged in an array, all templates having coplanar upper and lower surfaces, the template sides of any two adjacent templates being mutually abutted, adjacent templates being connected by fasteners through connecting holes, lifting slots on adjacent templates being symmetrical along the template sides, two or four lifting slots being able to be combined to form a lifting hole at the bottom of the template top surface and template side, the lifting hole being located on the sides of all two abutted longitudinal templates or transverse templates.

[0014] Furthermore, the lifting holes are located only on the sides of all two mating longitudinal templates or transverse templates.

[0015] The beneficial effects of this utility model are:

[0016] 1. The template of this utility model is provided with a connection hole on the side. By passing fasteners through the connection holes of two templates at the same time, the two adjacent templates are kept tightly connected, ensuring that there are no gaps between the templates. After the concrete is grouted, the connection is maintained and there will be no gaps or leakage of grout.

[0017] 2. The template of this utility model is provided with a lifting groove in the middle or edge of the template side. The lifting groove runs through the upper and lower surfaces of the template side. After the template is assembled, two or four lifting grooves can be spliced ​​together to form a lifting hole, which makes it convenient for lifting tools to pass through the lifting hole to realize the lifting operation.

[0018] 3. Compared with traditional templates, this utility model eliminates the need for scaffolding at the bottom during template assembly, thus reducing workload.

[0019] 4. The hoisting holes formed by the hoisting grooves of this utility model are arranged in multiple longitudinal rows, and two templates share one hoisting hole, which reduces the number of holes to be opened on the template, avoids grout leakage, reduces the number of sealing operation steps, and improves the flatness of the ribbed floor slab.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1-3As shown, a planar floor slab forming template is provided. The template includes a top surface 1, which is rectangular with a long side of 2400mm and a short side of 800mm. The top surface 1 is surrounded by downward-extending side surfaces 2, which are perpendicular to the top surface 1. The top surface 1 and the inner side of the enclosing side surfaces 2 form a cavity 3. The top surface 1 and the side surfaces 2 are provided with grid-like reinforcing ribs to ensure that the template achieves high overall strength with less material consumption. The template side 2 is provided with connecting holes 4. Six connecting holes 4 are provided on the long side of the template side 2, and two connecting holes 4 are provided on the short side of the template side 2. The connecting holes 4 are symmetrically arranged along the length of the template side 2 and are horizontally positioned, extending from the cavity 3 to the template side 2. The template side 2 is provided with lifting grooves 5. The lifting grooves 5 are located on the long side of the template side 2, and there are five lifting grooves 5 on a single template side 2. The lifting grooves 5 are symmetrically arranged along the length of the template side 2 and extend through the top surface 1 of the template and the bottom of the template side 2. The lifting grooves 5 and the connecting holes 4 are staggered. The cross-section of the lifting groove 5 is semi-circular.

[0031] In this scheme, the height of the top surface 1 of the template, the size of the template, and the thickness and height of the reinforcing ribs are designed according to the design stress requirements. Two adjacent templates can be connected by fasteners, which are fastened through the connection holes 4 of the two templates to ensure that there are no gaps between the templates and that there will be no leakage of grout during grouting. When the two templates are assembled, the lifting slot 5 forms a circular lifting hole, which makes it convenient for the lifting tools to pass through the circular hole from top to bottom, and supports the flange plate through the support plate to lift the template and realize the lifting. In this design, the lifting hole is formed by splicing lifting slots 5 on two templates, reducing the need for opening holes in the template. If a hole is opened in the middle of the template, a lifting tool must pass through the hole during installation. There will inevitably be multiple lifting holes, and it is difficult to align the holes, resulting in low efficiency. The template in this design allows for pre-installation of lifting tools, which include at least a suspension rod and a support plate. The template is then pushed in from the side, with the bottom edge of the template placed on the support plate. The template and another pre-installed template are placed close together, and the two lifting slots 5 are joined to form a lifting hole, enclosing the suspension rod. The two templates are then tightly connected by fasteners passing through the connecting holes 4. The entire installation process does not require lifting tools to pass through the holes, improving installation efficiency.

[0032] Example 2

[0033] like Figure 4-5As shown, four lifting slots 5 are provided on the side 2 of the template along the long side. Two of the lifting slots 5 are located in the middle of the side 2 of the template and have a semi-circular cross-section. The other two lifting slots 5 are located at the edge of the side 2 of the template, that is, at the four corners of the template. The lifting slots 5 at these corners have a quarter-circle cross-section. The middle lifting slot 5 can be combined with the lifting slot 5 on another template to form a lifting hole. The corner lifting slots 5 can be combined with the lifting slots 5 on the other three templates to form a lifting hole. This method can also realize the lifting of the template.

[0034] In other embodiments, the number of connection holes 4 on the side 2 of the template can be set to other numbers according to the template thickness, load requirements, and other conditions. The goal is to ensure a tight fit between the templates and prevent grout leakage.

[0035] In other embodiments, the cross-section of the hoisting groove 5 can also be one of the following: half a regular polygon, such as half a square, half a regular hexagon, half a regular octagon, etc.

[0036] In other embodiments, the lifting groove 5 can also be located on the side 2 of the template at the short side of the template. During installation, the lifting tool supports the bottom surface of the short side of the template, which can also achieve lifting.

[0037] Example 3

[0038] like Figure 6-7 As shown, another aspect of this utility model provides a planar floor slab forming template assembly, which uses twenty-seven templates arranged in three rows and nine columns. The template adopts the template structure of Embodiment 1. All templates have coplanar upper and lower surfaces. The template sides 2 of any two adjacent templates are attached to each other. Adjacent templates are connected by fasteners through the connecting holes 4. The lifting grooves 5 on adjacent templates are symmetrical along the template side 2. Two lifting grooves 5 can be combined to form a lifting hole that penetrates the upper and lower surfaces of the template. The lifting holes are located on the side 2 of the template at the long side of the template, thus forming eight parallel rows of lifting holes, with fifteen lifting holes in each row. Therefore, a total of one hundred and twenty lifting points are needed to support the edge of the template for lifting. Eight suspension beams can be used for lifting, with fifteen sets of lifting tools set under each suspension beam. The lifting tools include at least a suspension rod and a support plate. The bottom edge of the template is placed on the support plate, and the template clamps the suspension rod from both sides, surrounding the suspension rod in the lifting groove 5. Then, fasteners are used to tightly connect the two templates through the connection holes 4. The entire installation process does not require lifting tools to pass through the holes, and there is no need to erect full-span scaffolding, which improves installation efficiency.

[0039] In other embodiments, no connection holes 4 and lifting slots 5 are provided on the outermost side of the template array, which ensures that the concrete surface is smooth and flat after demolding and will not leak grout. Furthermore, it reduces the number of sealing steps and improves the flatness of the ribbed floor slab.

[0040] In other embodiments, the lifting slot 5 can also be located at the edge of the template side 2, that is, at the four corners of the template. Therefore, the lifting tool can support the corners of the four templates at the same time, which can reduce the number of lifting slots 5.

[0041] In summary, the planar floor slab forming template and template assembly described in this utility model can realize modular construction, and the template assembly can realize hoisting operations, while also reducing the number of template holes and improving the flatness of the ribbed floor slab.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and characteristics of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model.
