Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically relating to a single-sided prefabricated steel formwork plate snap-fit ​​structure. Background Technology

[0002] Current precast grid panels generally include a precast concrete layer, an insulation layer, and a cast-in-place layer. The cast-in-place layer usually has a steel mesh frame as its skeleton. The precast grid panels are prefabricated in the factory, then transported to the construction site for assembly, and then the pouring continues, which can improve construction efficiency.

[0003] To facilitate manufacturing and transportation, precast space frame panels are usually not too large in area. During the construction of walls, multiple precast space frame panels need to be spliced ​​together. Adjacent precast space frame panels are generally bonded with concrete. However, it takes a certain amount of time for the concrete to fully solidify, which affects the construction progress. If the concrete has not fully solidified, the connection between adjacent precast space frame panels is not firm, and the expansion of the concrete during the pouring of the cast-in-place layer can easily cause adjacent precast space frame panels to shift. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a single-sided precast steel formwork plate snap-fit ​​structure. By adding snap-fit ​​components, there is no need to wait for the concrete at the adjacent precast concrete layer to solidify. At the same time, the snap-fit ​​components are easy to install, improving construction efficiency and further enhancing the integrity of the internal structure of the wall formed by splicing precast components.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A single-sided precast steel formwork space frame plate snap-fit ​​structure is disclosed. The space frame plate is provided with multiple sets of overlapping components. The space frame plate includes a precast concrete layer, an insulation layer, and a cast-in-place layer. A steel mesh is provided in the cast-in-place layer. A snap-fit ​​component is added to the cast-in-place layer. The snap-fit ​​component includes a limiting clamp and a limiting buckle. The limiting buckle is located on the connecting side of the space frame plate. The limiting buckle forms a horizontal snap-fit ​​point for the limiting clamp to hold. The upper and lower sides of the limiting clamp clamp the limiting buckles of the upper space frame plate and the limiting buckles of the lower space frame plate to form a snap-fit ​​fixation.

[0007] Both the limiting clamp and the limiting buckle have a U-shaped groove structure. The open end of the limiting buckle faces the outside of the cast-in-place layer in the horizontal direction, and the opening of the limiting buckle is formed as a slot. The open end of the limiting clamp faces the limiting buckle in the horizontal direction. The upper and lower ends of the opening of the limiting clamp are respectively formed as inserts and are inserted into the slot. The upper and lower sets of inserts of the limiting clamp are respectively inserted into the two adjacent sets of limiting buckles of the adjacent space frame plate.

[0008] The limiting clamp and the limiting buckle are respectively provided with rack-shaped limiting protrusions on their contact sides in the horizontal direction. The limiting clamp and the limiting buckle are fixedly connected by the limiting protrusions.

[0009] The slot of the limiting buckle clamps the transverse steel bars of the steel mesh, and the end of the insert and the slot together surround the transverse steel bars. The limiting buckle forms a fixed connection by means of clamping and cooperating with the transverse steel bars.

[0010] The connecting side of the precast concrete layer is provided with a positioning structure that fits in a concave-convex shape, and adjacent space frame panels are spliced ​​and positioned by means of the positioning structure.

[0011] The beneficial effects of this utility model are:

[0012] This utility model adds a snap-fit ​​assembly, which fixes limiting buckles on the adjacent sides of adjacent space frame plates, and then clamps and fixes the adjacent limiting buckles of the upper and lower level space frame plates respectively by limiting clamps, thereby fixing the steel mesh of the upper and lower level space frame plates to each other through the snap-fit ​​assembly, and then fixing the adjacent space frame plates to each other.

[0013] The snap-fit ​​assembly eliminates the need to wait for the concrete in the adjacent precast concrete layers to solidify. At the same time, the snap-fit ​​assembly is easy to install, which improves construction efficiency and further enhances the integrity of the internal structure of the wall formed by splicing precast components.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Specific embodiments, such as Figure 1-3As shown, this utility model provides a single-sided precast steel formwork space frame plate snap-fit ​​structure. The space frame plate is provided with multiple sets of overlapping upper and lower parts. The space frame plate includes a precast concrete layer 1, an insulation layer 2, and a cast-in-place layer 3. A steel mesh 4 is provided in the cast-in-place layer 3. A snap-fit ​​component is added to the cast-in-place layer 3. The snap-fit ​​component includes a limiting clamp 5 and a limiting buckle 6. The limiting buckle 6 is located on the connecting side of the space frame plate. The limiting buckle 6 forms a snap-fit ​​point in the horizontal direction for the limiting clamp 5 to clamp. The upper and lower sides of the limiting clamp 5 clamp the limiting buckle 6 of the upper space frame plate and the limiting buckle 6 of the lower space frame plate to form a snap-fit ​​fixation.

[0020] To facilitate manufacturing and transportation, precast space frame panels are usually not too large in area. During the construction of the wall, multiple precast space frame panels need to be spliced ​​together. Adjacent precast space frame panels are generally bonded with concrete. However, it takes a certain amount of time for the concrete to fully solidify, which affects the construction progress. If the concrete has not fully solidified, the connection between adjacent precast space frame panels is not firm. During the process of pouring concrete into the cast-in-place layer 3, the expansion of the concrete can easily cause adjacent precast space frame panels to shift.

[0021] Therefore, this utility model adds a snap-fit ​​assembly, and fixes the limiting buckles 6 on the adjacent side of the adjacent space frame plates respectively. Then, the limiting clamps 5 clamp and fix the adjacent limiting buckles 6 of the upper and lower level space frame plates respectively, so as to fix the steel mesh 4 of the upper and lower level space frame plates to each other through the snap-fit ​​assembly, and then fix the adjacent space frame plates to each other.

[0022] The snap-fit ​​assembly eliminates the need to wait for the concrete in the adjacent precast concrete layer 1 to solidify. At the same time, the snap-fit ​​assembly is easy to install, which improves construction efficiency and further enhances the integrity of the internal structure of the wall formed by splicing precast components.

[0023] like Figure 2-3 As shown, both the limiting clamp 5 and the limiting buckle 6 have a U-shaped groove structure. The open end of the limiting buckle 6 faces the outside of the cast-in-place layer 3 in the horizontal direction, and the opening of the limiting buckle 6 is formed as a slot 7. The open end of the limiting clamp 5 faces the limiting buckle 6 in the horizontal direction. The upper and lower ends of the opening of the limiting clamp 5 are respectively formed as inserts 8 and are inserted into the slot 7. The upper and lower sets of inserts 8 of the limiting clamp 5 are respectively inserted into the two adjacent sets of limiting buckles 6 of the adjacent space frame plate. By inserting the inserts 8 of the limiting clamp 5 into the limiting buckles 6 of the upper and lower level space frame plates and forming a snap-fit, the connection stability between the upper and lower level space frame plates can be guaranteed.

[0024] like Figure 2-3As shown, the limiting clamp 5 and the limiting buckle 6 are respectively provided with rack-shaped limiting protrusions 9 on their contact sides along the horizontal direction. The limiting clamp 5 and the limiting buckle 6 form a concave-convex fit and are fixedly connected by the limiting protrusions 9. The rack-shaped concave-convex fit structure makes the limiting clamp 5 and the limiting buckle 6 form a stable fixed connection, improving the connection firmness between adjacent space frame plates.

[0025] like Figure 2-3 As shown, the slot 7 of the limiting buckle 6 clamps the transverse steel bar 401 of the steel mesh frame 4. The end of the insert block 8 and the slot 7 together surround the transverse steel bar 401. The limiting buckle 6 forms a fixed connection by clamping with the transverse steel bar 401. The clamping component and the steel mesh frame 4 are fixed by clamping, which eliminates the need for welding, binding and other methods, making installation more convenient and faster.

[0026] like Figure 1 As shown, the connecting side of the precast concrete layer 1 is provided with a positioning structure 10 that fits in a concave-convex shape. Adjacent space frame panels are spliced ​​and positioned by means of the positioning structure 10. The positioning structure 10 can quickly position and splice adjacent space frame panels, while increasing the contact area between adjacent space frame panels, increasing the amount of concrete applied, and making the adjacent space frame panels better bonded and fixed.
