Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a snap pad for construction engineering. Background Art

[0002] Reinforced concrete structures have high bearing capacity because they combine the advantages of high compressive strength of concrete, high tensile strength of steel bars, and good bond between steel bars and concrete. Therefore, they are widely used in engineering construction. In building concrete structures, concrete cover is often used to protect steel bars. The thickness of the concrete cover has an important impact on the bond anchorage capacity of steel bars, prevention of steel bar corrosion, and durability performance.

[0003] After the steel bars are tied, formwork needs to be fixed around the steel bars, and a certain distance needs to be left between the steel bars and the formwork, and this distance is the thickness of the concrete cover of the steel bars. In actual construction, in order to make the thickness of the concrete cover of the steel bars meet the requirements of specifications and standards, prefabricated pads are generally pre-pierced on the steel bars to separate the steel bars from the formwork. At present, the prefabricated pads for the concrete cover of steel bars generally adopt an integral pad with a hole opened in the center. When tying steel bars, multiple such pads are pre-pierced through the holes in the center from one end of the steel bars, and the positions of each pad need to be adjusted in advance. Therefore, the installation of such pads is relatively cumbersome, time-consuming and laborious. Summary of the Utility Model

[0004] The utility model provides a snap pad for construction engineering, which solves the problem that the current pads for the concrete cover of steel bars are relatively cumbersome to install.

[0006] The semi-circular pad includes a semi-circular outer backing plate and a semi-circular inner backing plate;

[0007] Both ends of the inner backing plate and both ends of the outer backing plate are respectively connected by connecting plates, and the two connecting plates are fixed by the snap;

[0008] A hole capable of passing through steel bars is formed between the two inner backing plates.

[0014] Preferably, a clamping plate is fixedly connected to the end of the sliding rod located outside the semi-circular cushion block.

[0015] Preferably, a connecting block is fixed to the end of the spring piece close to the outer cushion plate, and the connecting block is fixedly connected to the inner side surface of the outer cushion plate.

[0016] Preferably, a connecting gasket is fixed to the end of the sliding rod extending into the semi-circular cushion block.

[0017] Preferably, connecting pieces are respectively arranged at both ends of the spring piece;

[0018] The end of the spring piece close to the outer cushion plate is fixedly connected to the connecting block through the connecting piece;

[0019] The end of the spring piece close to the inner cushion plate is fixedly connected to the connecting gasket through the connecting piece.

[0020] Preferably, the buckle is U-shaped, and hooks are respectively arranged at one ends of both side walls of the buckle at the opening.

Detailed Embodiment

[0035] The following further elaborates on the present utility model in detail in conjunction with the drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0036] The present utility model provides a building engineering buckle cushion block, as shown in Figure 1 and Figure 4As shown, it includes a buckle 2 and two semi-circular cushion blocks 1. The semi-circular cushion block 1 includes a semi-circular outer cushion plate 11 and a semi-circular inner cushion plate 12. The two ends of the inner cushion plate 12 and the two ends of the outer cushion plate 11 are respectively connected by connecting plates 15. The two connecting plates 15 are fixed by the buckle 2. A hole capable of passing through the steel bar 3 is formed between the two inner cushion plates 12.

[0037] After the steel bar 3 skeleton is tied up, set the steel bar 3 protection layer cushion blocks at the specified positions. When installing the steel bar 3 protection layer cushion blocks, first clamp the two semi-circular sliding cushion blocks on the steel bar 3, so that the steel bar 3 is clamped in the hole formed between the two inner cushion plates 12, and then fix the upper and lower ends of the two semi-circular cushion blocks 1 respectively through the two buckles 2. In this way, it is more convenient to install the steel bar 3 protection layer cushion blocks on the steel bar 3, and it can be installed after the steel bar 3 skeleton is completed, avoiding the displacement of the steel bar 3 protection layer cushion blocks during the tying of the steel bar 3 skeleton and saving the process of adjusting the position of the cushion blocks in the later stage.

[0038] As Figure 4 shown, arc-shaped support plates 13 are respectively arranged between the front and rear sides of the inner cushion plate 12 and the outer cushion plate 11;

[0039] Through holes 14 are respectively formed between the two ends of the support plate 13 and the upper and lower two connecting plates 15.

[0040] The support plate 13 can improve the supporting force of the semi-circular cushion block 1 and prevent the semi-circular cushion block 1 from deforming.

[0041] As Figure 4 shown, a plurality of sliding holes 121 are circumferentially formed on the surface of the inner cushion plate 12.

[0042] As Figure 2 shown, a plurality of elastic components 4 are circumferentially arranged between the inner cushion plate 12 and the outer cushion plate 11;

[0043] The elastic component 4 includes a sliding rod 43 and a spring piece 41 with a zigzag cross-section. The spring piece 41 can also be replaced by a spring. The sliding rod 43 slides in the sliding hole 121. The two ends of the spring piece 41 are respectively fixedly connected to the inner side surface of the outer cushion plate 11 and the sliding rod 43;

[0044] A clamping plate 5 is fixedly connected to the end of the sliding rod 43 located outside the semi-circular cushion block 1.

[0045] As Figure 3 shown, further, an anti-slip plate 51 is arranged on the outer side surface of the clamping plate 5.

[0046] As Figure 3 shown, further, a connecting block 44 is fixed at one end of the spring piece 41 close to the outer cushion plate 11, and the connecting block 44 is fixedly connected to the inner side surface of the outer cushion plate 11;

[0047] One end of the sliding rod 43 extending into the semi-circular cushion block 1 is fixed with a connecting gasket 45.

[0048] The setting of the connecting block 44 can make the spring piece 41 and the outer backing plate 11 more stably connected, and the setting of the connecting gasket 45 can make the spring piece 41 and the sliding rod 43 more stably connected.

[0049] As Figure 3 shown, further, connecting pieces 42 are respectively arranged at both ends of the spring piece 41. One end of the spring piece 41 close to the outer backing plate 11 is fixedly connected with the connecting block 44 through the connecting piece 42, and one end of the spring piece 41 close to the inner backing plate 12 is fixedly connected with the connecting gasket 45 through the connecting piece 42.

[0050] The connecting pieces 42 are respectively arranged at both ends of the spring piece 41, which can increase the contact area between both ends of the spring piece 41 and the connecting block 44 and the connecting gasket 45 respectively, and further increase the connection stability between both ends of the spring piece 41 and the connecting block 44 and the connecting gasket 45 respectively.

[0051] As Figure 5 shown, the buckle 2 is U-shaped, and hooks 21 are respectively arranged at one ends of both side walls of the buckle 2 at the opening.

[0052] As Figure 5 shown, further, the opposite surfaces of the two hooks 21 are inclined surfaces.

[0053] The inclined surfaces of the two hooks 21 play a guiding role, and can more smoothly drive the two side walls of the buckle 2 to insert into the through hole 14.

[0054] Adopting the present utility model, after the steel bar 3 skeleton is tied up, steel bar 3 protective layer cushion blocks are arranged at the specified positions. When installing the steel bar 3 protective layer cushion blocks, first, the two semi-circular sliding cushion blocks are clamped on the steel bar 3, the anti-slip plate 51 on the outside of the clamping plate 5 contacts the surface of the steel bar 3 to clamp the steel bar 3, and then the upper and lower ends of the two semi-circular cushion blocks 1 are respectively fixed by the two buckles 2. When installing the buckle 2, the inclined surface of the hook 21 first abuts against the front side of the connecting plate 15, and the buckle 2 is continuously pushed into the through hole 14. The two side walls of the buckle 2 separate. After the hook 21 extends out from the other end of the through hole 14, the hook 21 is clamped on the rear side of the connecting plate 15, and the two side walls of the buckle 2 clamp the left and right two connecting plates 15, completing the installation of the steel bar 3 protective layer cushion block. In this way, it is more convenient to install the steel bar 3 protective layer cushion block on the steel bar 3, and it can be installed after the steel bar 3 skeleton is completed, avoiding the position movement of the steel bar 3 protective layer cushion block during the tying of the steel bar 3 skeleton, and saving the process of adjusting the position of the cushion block in the later stage;

[0055] When installing the spacer on the thicker steel bar 3, the spacer is installed in the same way as described above. However, during the installation process, since the steel bar 3 is thickened, the steel bar 3 will push the clamping plate 5 towards the inner spacer plate 12, the sliding rod 43 slides into the semi-circular spacer 1, and the spring piece 41 is compressed. In this way, the spacer can adapt to steel bars 3 of various diameters and has strong applicability.
