Description

Technical Field

[0001] This utility model relates to the field of concrete formwork technology, specifically a formwork for concrete construction. Background Technology

[0002] Concrete formwork is a temporary support structure whose main purpose is to ensure the quality and safety of concrete projects, accelerate the construction progress and reduce project costs. It is used to keep concrete structures and components in the specified position and geometric dimensions during concrete construction, and to bear the self-weight of the building formwork and external loads.

[0003] Chinese patent CN220285294U discloses a formwork suitable for concrete construction, comprising a plate body, connecting components, and auxiliary structures. The connecting components are disposed on both sides of the plate body, and the auxiliary structures are installed on the plate body. The connecting components include limiting components and fixing components. The limiting components include fittings and slots. The fittings are of a straight-line structure, and the slots are located on both sides of the plate body. During concrete pouring after installation, adjacent plates will bear the horizontal load generated by the concrete, which can easily lead to deformation at the plate connection, affecting the stability of the formwork support and the safety of the concrete structure. By using the connecting components between the formworks, adjacent formworks can be aligned and fixed through the connecting components, which facilitates installation and fixation, enhances the stability of the connection, and prevents the formwork from deforming due to concrete pressure, thereby improving the convenience, safety, and stability of the formwork.

[0004] The above-mentioned template has the effect of strengthening the stability of the connection. However, since a large number of grooves are opened on the plate and the connecting parts, there are many dead corners for cleaning. In addition, the existing structure has poor impact resistance. Furthermore, the connecting parts and the plate need to be stored separately, which can easily lead to the loss of the connecting parts. Therefore, it is necessary to provide a template for concrete construction. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a formwork for concrete construction, comprising a formwork base plate, wherein a nesting mechanism is provided on the formwork base plate; the nesting mechanism includes two snap plates and two snap grooves, the two snap plates are respectively fixedly installed on both sides of the formwork base plate, the two snap grooves are respectively opened on the other two sides of the formwork base plate, an arc-shaped seat is fixedly installed on one side of each of the two snap plates, two limiting plates are respectively fixedly installed on the two snap grooves, and a handle is fixedly installed on one side of the formwork base plate.

[0007] Preferably, the two snap plates and the two snap grooves are located sequentially on adjacent sides of the template base plate, and the snap plates and snap grooves are adaptively matched.

[0008] Preferably, the buckle plate is fixedly installed at an angle on one side of the template base plate, and the inside of the buckle groove is provided with a slope.

[0009] Preferably, the template base plate is provided with a fastening mechanism, which includes two positioning seats. The two positioning seats are respectively fixedly installed in the middle of the two limiting plates, and fastening bolts are threaded on both positioning seats. A knob is fixedly installed at one end of the fastening bolt, and fastening collars are fixedly installed at the four corners of the template base plate.

[0010] Preferably, the positioning seat is fixedly mounted on the limiting plate at an angle, and the positioning seat is perpendicular to the surface of the buckle groove.

[0011] Preferably, the angles of the four fastening collars are all the same, and the four fastening collars protrude from the limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This is a formwork for concrete construction. By installing two snap plates and opening two snap grooves on the four sides of the formwork base plate, the quick connection between the formwork base plates can be achieved by controlling the matching of the snap plates and snap grooves. The inclined installation of the snap plates can increase the stability of the connection between the two formwork base plates. The inside of the snap groove is set with a slope to make it easier to remove concrete lumps.

[0014] 2) This is a formwork for concrete construction. After the formwork base plate is connected by the snap plate and the snap groove, the tightening bolts can be rotated to apply pressure to the snap plate. Thanks to the inclined installation of the positioning seat and the snap plate, the two formwork base plates cannot be pulled apart laterally. The tightening collar is used to fit the reinforcing bars, which increases the stability of the formwork base plate connection. At the same time, the snap-fit ​​and integrated design effectively avoids the loss of the connecting parts. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] Combination Figure 1 and Figure 2 A formwork for concrete construction includes a formwork base plate 1, on which a nesting mechanism 2 is provided; the nesting mechanism 2 includes two snap plates 201 and two snap grooves 202, the two snap plates 201 are respectively fixedly installed on both sides of the formwork base plate 1, the two snap grooves 202 are respectively opened on the other two sides of the formwork base plate 1, an arc-shaped seat 203 is fixedly installed on one side of each of the two snap plates 201, two limiting plates 204 are respectively fixedly installed on the two snap grooves 202, and a handle 205 is fixedly installed on one side of the formwork base plate 1.

[0023] Two snap-on plates 201 and two snap-on grooves 202 are located sequentially on adjacent sides of the template base plate 1. The snap-on plates 201 and snap-on grooves 202 are adaptively matched to ensure that several template base plates 1 can be matched and connected together. The snap-on plates 201 are fixedly installed at an angle on one side of the template base plate 1. The snap-on grooves 202 are provided with a slope inside. Benefiting from the angled installation of the snap-on plates 201 and the angled opening of the snap-on grooves 202, the impact resistance of the template base plate 1 is increased when connected, and it is also convenient to clean the concrete residue inside the snap-on grooves 202.

[0024] Example 2

[0025] refer to Figure 3 and Figure 4 The template base plate 1 is provided with a fastening mechanism 3, which includes two positioning seats 301. The two positioning seats 301 are respectively fixedly installed in the middle of the two limiting plates 204, and fastening bolts 302 are threaded on both positioning seats 301. A knob 303 is fixedly installed on one end of the fastening bolt 302. Fastening collars 304 are fixedly installed at the four corners of the template base plate 1.

[0026] The positioning seat 301 is fixedly installed on the limiting plate 204 at an angle, and the positioning seat 301 is perpendicular to the surface of the buckle groove 202. After the two template base plates 1 are connected by the buckle plate 201 and the buckle groove 202, the fastening bolt 302 is moved relative to the positioning seat 301 by rotating the knob 303. Since the positioning seat 301 is perpendicular to the surface of the buckle groove 202, the fastening bolt 302 will strengthen the connection between the buckle plate 201 and the buckle groove 202. The angles of the four fastening collars 304 are all the same, and the four fastening collars 304 protrude from the limiting plate 204. When in use, steel bars can be embedded in the fastening collars 304 to increase the stability of the template.

[0027] In actual operation, by installing the buckle plate 201 at an angle and opening the buckle groove 202, several template base plates 1 can be connected through the buckle plate 201 and the buckle groove 202. Benefiting from the installation of the buckle plate 201 at an angle and the opening of the buckle groove 202 at an angle, the impact resistance of the template base plate 1 is increased when connected, and it is also convenient to clean the concrete residue inside the buckle groove 202. Among them, the limiting plate 204 plays a limiting role to prevent the template from falling off due to concrete impact.

[0028] After the two template base plates 1 are connected by the snap plate 201 and the snap groove 202, the fastening bolt 302 is moved relative to the positioning seat 301 by rotating the knob 303. Since the positioning seat 301 is perpendicular to the surface of the snap groove 202, the fastening bolt 302 will strengthen the connection between the snap plate 201 and the snap groove 202. At the same time, the angles of the four fastening collars 304 are all the same, and the four fastening collars 304 protrude from the limiting plate 204. Reinforcing bars can be embedded in the fastening collars 304 to increase the stability of the template.
