Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a connecting clip for steel truss floor decking. Background Technology

[0002] Currently, the bottom formwork steel truss floor deck connectors on the market can be divided into two types according to the material: metal and plastic. Among them, plastic connectors are mostly snap-on, which are quick and easy to install. However, due to the insufficient rigidity of plastic itself, its resistance to deformation is insufficient, and it cannot meet the fire resistance requirements. Metal connectors mostly use hollow steel, C-shaped steel and other formed products, and are mostly welded to the truss for fixation. Other styles of connector clips are also used.

[0003] The prior art discloses a connector in a non-removable steel truss floor deck with application number CN202122488601.X. The technical solution involves several connectors arranged in a row, parallel to each other and aligned at both ends, on the upper surface of the floor deck bottom formwork. The steel truss is installed on the connectors arranged in a row. Supports are vertically arranged above the two opposite sides of the connector's base plate. The top surface of the support has convex arc surfaces extending downwards at both ends. A groove is provided inwards below the bottom edge of the convex arc surface, and a concave arc surface extends upwards from the bottom edge of the groove. The two lower chords of the steel truss are respectively fitted into the two grooves. However, the base plate in this technical solution is flat, and the connectors are prone to rotation during the assembly and nailing process with the bottom formwork, making it difficult to secure the truss. Therefore, generally two nails are needed for each connector, increasing the assembly workload and reducing assembly efficiency. Furthermore, the connector itself is a three-sided open structure, lacking a secure bond with the concrete after pouring, posing a risk of detachment.

[0004] Therefore, it is necessary to propose an improvement to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems in the prior art and provide a connecting buckle for steel truss floor decking, which solves the problems of positioning misalignment during installation and detachment after concrete pouring.

[0006] The technical solution of this utility model is:

[0007] A connecting clip for steel truss floor decking includes a clip plate and a connecting plate. The connecting plate has clip plates on both the front and rear sides, and symmetrical clip grooves on the left and right sides. The connecting plate has downward-extending claws along its edges.

[0008] As a preferred technical solution, the left and right sides of the connecting plate are arc-shaped, the claws are first pointed claws, and the connecting plate is provided with first pointed claws on both the left and right sides.

[0009] As a preferred technical solution, the left and right sides of the connecting plate are straight edges, the claws are second sharp claws, and the connecting plate is provided with second sharp claws on both the left and right sides.

[0010] As a preferred technical solution, the left and right sides of the connecting plate are arc-shaped, and the arc shape of the connecting plate is tilted downward to form a second claw.

[0011] As a preferred technical solution, the left and right sides of the connecting plate are straight edges, and the straight edges of the connecting plate are turned downwards at an angle to form a third claw.

[0012] As a preferred technical solution, the left and right sides of the connecting plate are straight edges, and the claws are irregularly pointed third claws. The connecting plate is provided with third claws on both the left and right sides, and the third claws have their tips pointing downwards.

[0013] As a preferred technical solution, the card plate is provided with casting holes.

[0014] As a preferred technical solution, the plate on the upper or lower edge of the pouring hole is provided with an outward flange.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model relates to a connecting clip for steel truss floor decking. By setting a clip plate and a connecting plate, and opening a slot on the clip plate, it enables rapid installation of the steel truss and improves the installation efficiency of the steel truss. The connecting plate has claws at both ends, which effectively avoids the problem of rotational displacement of the connecting clip during the process of snapping the steel truss to the connecting clip. At the same time, each connecting clip only needs to be connected with a single self-tapping screw, reducing the assembly and nailing workload by half and improving the installation efficiency of the connecting clip. The overall assembly efficiency is increased by more than 50%. The pouring hole and its outward flange can effectively prevent the hollowing caused by the connection parts falling off, the bottom formwork falling off and other engineering quality risks.

[0028] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0029] Example 1:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is a structural schematic of the connecting buckle of the first embodiment of this utility model.

[0031] The connecting buckle for the steel truss floor deck in this embodiment includes a clamping plate 2 and a connecting plate 3. The connecting plate 3 has clamping plates 2 on both the front and rear sides, and the two clamping plates 2 have clamping slots 1 on both the left and right sides. The clamping slots 1 are arc-shaped with the opening facing upwards. The clamping slots 1 are used for the installation of the steel truss. The installation height of the steel truss is usually controlled by controlling the height of the clamping slots 1 on the clamping plate 2, thereby controlling the thickness of the steel reinforcement protective layer in the floor deck.

[0032] Both clamping plates 2 have pouring holes 9 in the middle. The pouring holes 9 ensure the compactness of the concrete poured into the cavity of the connecting clamp, thereby ensuring the strength of the poured floor slab. The upper or lower edge of the pouring hole 9 is provided with an outward flange 8. The outward flange 8 ensures the support strength of the connecting clamp and plays a good role in positioning and preventing hollowing and falling off after the concrete is poured.

[0033] The left and right sides of the connecting plate 3 are arc-shaped, and a first claw 4 is provided at the arc edge of the connecting plate 3. The first claw 4 is an inverted triangle with the pointed corner facing down. When the connecting buckle is installed, the first claw is inserted into the bottom template 11 for fixing the connecting buckle, which facilitates the pre-positioning and installation of the connecting buckle. It is possible to fix the connecting plate by setting the first claw 4 on one side edge of the connecting plate 3. Setting the first claw 4 on both sides edge of the connecting plate 3 can better fix the connecting plate. It can effectively prevent the connecting buckle and the bottom template 11 from being rotated and shifted due to external forces during the transportation and turnover process after being connected by a screw. It can also solve the problem of the connecting buckle rotating and shifting during the connection between the steel truss and the connecting buckle.

[0034] like Figure 5 The diagram shown is a structural schematic of the steel truss of this utility model.

[0035] The steel truss includes an upper chord 5, a lower chord 7, and web reinforcement 6. Lower chord 7 is provided below both sides of the upper chord 5. Web reinforcement 6 is fixedly connected to the two lower chord 7 and the upper chord 5. The distance between the two slots 1 of the clamping plate 2 is not less than the distance between the two lower chord 7. The diameter of the slot 1 is larger than the diameter of the lower chord 7. The opening depth of the slot 1 is not less than the radius of the lower chord 7. This not only facilitates the installation of the lower chord 7, but also prevents the lower chord 7 from sliding out after being inserted into the slot 1, ensuring the ease of installation and the secure connection between the lower chord 7 and the slot 1.

[0036] like Figure 6 The diagram shown is a schematic diagram of the installation of the connecting buckle and the steel truss of this utility model.

[0037] The lower end of the connecting clip is provided with a bottom template 11. The connecting clip and the bottom template 11 are connected and fixed by fixing screws 10. When the connecting clip is installed, the first claw 4 is inserted into the bottom template 11 to prevent the connecting clip from rotating or shifting. Multiple connecting clips are installed at intervals on the bottom template 11. Among them, the lower chord bar 7 of the steel truss is inserted into the slot 1 of the connecting clip, realizing the quick installation of the connecting clip and the steel truss.

[0038] Example 2:

[0039] like Figure 7 The diagram shown is a structural schematic of the connecting buckle of the second embodiment of this utility model.

[0040] In the second embodiment, the connecting plate 3 of the connecting buckle has straight edges on both the left and right sides, and a second claw 43 is provided on both the left and right sides of the connecting plate 3. The second claw 43 is an inverted triangle with the pointed corner pointing downwards.

[0041] Example 3:

[0042] like Figure 8 The diagram shown is a structural schematic of the connecting buckle of the third embodiment of this utility model.

[0043] In the third embodiment, the connecting plate 3 of the connecting buckle has arc-shaped left and right sides. The arc-shaped edge of the connecting plate 3 is flipped downwards to form a second claw 42. The arc-shaped end of the second claw 42 extends downwards.

[0044] Example 4:

[0045] like Figure 9 The diagram shown is a structural schematic of the connecting buckle of the fourth embodiment of this utility model.

[0046] In the fourth embodiment, the left and right sides of the connecting plate 3 of the connecting buckle are straight edges. The straight edges of the connecting plate 3 are flipped downwards to form a third claw 44, and the straight edges of the third claw 44 extend downwards.

[0047] Example 5:

[0048] like Figure 10 The diagram shown is a structural schematic of the connecting buckle according to the fifth embodiment of this utility model.

[0049] The edge of the connecting plate 3 of the fifth embodiment is a straight edge, and an irregularly shaped third claw 45 is provided at the edge of the connecting plate 3. The third claw 45 has a pointed tip extending downward.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
