Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a grout-proof structure for steel truss floor decking. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. The floor decking is fabricated on the ground and installed on-site by hoisting. Its advantages are faster construction progress and lower cost.

[0003] Currently, in the construction of existing steel truss floor decks, the joints between two adjacent floor decks are mainly sealed by adhesive strips. However, when pouring concrete, the uneven stress at the connection between the two adjacent floor decks can easily cause the adhesive strips at the connection to break, resulting in gaps and poor sealing. This can lead to grout leakage when pouring concrete. Utility Model Content

[0004] To solve the above problems, this utility model provides a grout-proof structure for steel truss floor decking.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel truss floor deck anti-grouting structure, comprising a first U-shaped plate and a connecting block respectively disposed on both sides of the floor deck body, wherein a second U-shaped plate is disposed on the connecting block, the first U-shaped plate comprising a first vertical plate and a second vertical plate disposed at intervals and a first horizontal plate connecting the bottom of the first vertical plate and the second vertical plate, the second U-shaped plate comprising a third vertical plate and a fourth vertical plate disposed at intervals and a second horizontal plate connecting the bottom of the third vertical plate and the fourth vertical plate, wherein the distance between the adjacent sides of the first vertical plate and the second vertical plate is the same as the distance between the sides of the third vertical plate and the fourth vertical plate that are far away from each other, a retaining strip is disposed on the upper part of the side of the fourth vertical plate that is far away from the first vertical plate, and a retaining groove is disposed on the side of the first vertical plate that is adjacent to the second vertical plate corresponding to the retaining strip.

[0006] By adopting the above technical solution, a first U-shaped plate, a connecting block, and a second U-shaped plate are set up. During the installation of the floor decking, the second U-shaped plate is inserted downwards into the first U-shaped plate. During this process, the locking strip first contacts the top of the first upright plate, causing the locking strip to push the fourth upright plate to bend. When the locking strip moves to the slot, the fourth upright plate returns to its original position, and the locking strip is engaged in the slot. This not only limits the position of the second U-shaped plate but also blocks the concrete grout. At the same time, the first upright plate and the fourth upright plate are attached, and the second upright plate and the third upright plate are attached, forming two sealing surfaces with good sealing effect, preventing grout leakage.

[0007] Furthermore, the card strip is generally triangular in shape, and the top surface of the card strip is parallel to the horizontal plane.

[0008] By adopting the above technical solution, the card strip is set in the shape of a triangular strip, so that when the fourth upright plate descends and drives the card strip to descend, the inclined surface on the lower side of the card strip contacts the first upright plate, thus preventing the card strip from getting stuck on the top edge of the first upright plate.

[0009] Furthermore, the card strips and card slots are each arranged vertically at intervals.

[0010] By adopting the above technical solution, several card strips and card slots are vertically spaced to enhance the sealing effect.

[0011] Furthermore, several compression springs are provided between the third and fourth upright plates.

[0012] By adopting the above technical solution and setting a compression spring, the compression spring provides elastic force in opposite directions to the third and fourth upright plates, resulting in a better fit between the first and fourth upright plates and between the second and third upright plates.

[0013] Furthermore, a reinforcing plate is provided on the side of the fourth upright plate adjacent to the third upright plate, and the orthographic projections of several of the card strips are all located within the area of ​​the reinforcing plate. One end of the compression spring is connected to the third upright plate, and the other end is connected to the reinforcing plate.

[0014] By adopting the above technical solution, a reinforcing plate is set on the side of the fourth upright plate adjacent to the third upright plate to increase the structural strength of the clip and the first upright plate, and to prevent the clip from deforming and failing to fit tightly with the slot, thereby affecting the sealing effect.

[0015] Furthermore, an inclined plate is provided between the second horizontal plate and the fourth vertical plate. The distance between the lower side of the inclined plate and the third vertical plate is less than the distance between the upper side of the inclined plate and the third vertical plate. The lower side of the inclined plate is connected to the second horizontal plate, and the upper side is connected to the fourth vertical plate.

[0016] By adopting the above technical solution, an inclined plate is set to reduce the width of the second horizontal plate, making it easier for the second U-shaped plate to be inserted downward into the first U-shaped plate.

[0017] Furthermore, a rubber strip is provided on the first horizontal plate, with the bottom of the rubber strip fixedly connected to the top surface of the first horizontal plate and the side of the rubber strip fixedly connected to the side wall of the first vertical plate.

[0018] By adopting the above technical solution, a rubber strip is set on the second horizontal plate. After the second U-shaped plate is inserted into the first U-shaped plate, the rubber strip abuts against the inclined plate, thereby increasing the sealing effect.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, a first U-shaped plate, a connecting block, and a second U-shaped plate are provided. During the installation of the floor decking, the second U-shaped plate is inserted downwards into the first U-shaped plate. During this process, the locking strip first contacts the top of the first upright plate, causing the locking strip to push the fourth upright plate to bend. When the locking strip moves to the slot, the fourth upright plate returns to its original position, and the locking strip is inserted into the slot. This not only limits the position of the second U-shaped plate but also blocks the concrete slurry. At the same time, the first upright plate and the fourth upright plate are in contact, and the second upright plate and the third upright plate are in contact, forming two sealing surfaces with good sealing effect and preventing slurry leakage.

[0021] 2. In this application, a compression spring is provided, which provides elastic force in opposite directions to the third and fourth upright plates, so that the fit between the first and fourth upright plates and between the second and third upright plates is better.

[0022] 3. In this application, a reinforcing plate is provided on the side of the fourth upright plate adjacent to the third upright plate to increase the structural strength of the clip and the first upright plate, and to prevent the clip from deforming and failing to fit tightly with the slot, thereby affecting the sealing effect.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4As shown in the embodiment of this application, a grout-proof structure for reinforced truss floor decking is disclosed, including a first U-shaped plate 10, a connecting block 20, and a second U-shaped plate 30. The first U-shaped plate 10 and the connecting block 20 are respectively disposed on both sides of the floor decking body 1. The second U-shaped plate 30 is disposed on the connecting block 20. The first U-shaped plate 10 includes a first vertical plate 11 and a second vertical plate 12 disposed at intervals, and a first horizontal plate 13 connecting the bottom of the first vertical plate 11 and the second vertical plate 12. The second U-shaped plate includes a third vertical plate 31 and a fourth vertical plate 32 disposed at intervals. The second horizontal plate 33 connects the bottom of the third vertical plate 31 and the fourth vertical plate 32. The distance between the adjacent sides of the first vertical plate 11 and the second vertical plate 12 is the same as the distance between the opposite sides of the third vertical plate 31 and the fourth vertical plate 32. The thickness of the connecting block 20 is the same as the thickness of the second vertical plate 12. After the second U-shaped plate 30 is inserted into the first U-shaped plate 10, the first vertical plate 11 and the fourth vertical plate 32 are attached, and the second vertical plate 12 and the third vertical plate 31 are attached, forming two sealing surfaces with good sealing effect and avoiding grout leakage. A retaining strip 34 is provided on the upper part of the side of the fourth upright plate 32 away from the first upright plate 11. A retaining groove 14 is provided on the side of the first upright plate 11 adjacent to the retaining strip 34. When the second U-shaped plate 30 is inserted downwards into the first U-shaped plate 10, the retaining strip 34 first contacts the top of the first upright plate 11, causing the retaining strip 34 to push the fourth upright plate 32 to bend. When the retaining strip 34 moves to the retaining groove 14, the fourth upright plate 32 returns to its original position, and the retaining strip 34 is inserted into the retaining groove 14. This serves to limit the position of the second U-shaped plate 30 and block the concrete slurry. When the retaining block is stuck on the upper edge of the first upright plate 11, preventing the second U-shaped plate 30 from being inserted into the first U-shaped plate 10, the top of the fourth upright plate 32 can be tapped with a tool to insert the second U-shaped plate 30 into the first U-shaped plate 10.

[0030] Specifically, the retaining strip 34 is triangular in shape, with its top surface parallel to the horizontal plane. This ensures that when the fourth vertical plate 32 descends, causing the retaining strip 34 to descend, the lower slope of the retaining strip 34 contacts the first vertical plate 11, preventing the retaining strip 34 from getting stuck on the top edge of the first vertical plate 11. Several retaining strips 34 and retaining grooves 14 are vertically spaced to enhance the sealing effect.

[0031] During installation, several compression springs 35 are installed between the third upright plate 31 and the fourth upright plate 32. These springs provide opposing elastic forces to the third and fourth upright plates 31 and 32, resulting in better contact between the first upright plate 11 and the fourth upright plate 32, and between the second upright plate 12 and the third upright plate 31. A reinforcing plate 36 is installed on the side of the fourth upright plate 32 adjacent to the third upright plate 31. The orthographic projections of several retaining strips 34 are all located within the surface area of ​​the reinforcing plate 36. One end of each compression spring 35 is connected to the third upright plate 31, and the other end is connected to the reinforcing plate 36, increasing the structural strength of the retaining strips 34 and the first upright plate 11, preventing deformation of the retaining strips 34 that would prevent them from tightly fitting with the retaining groove 14 and thus affecting the sealing effect. Reinforcing ribs are also installed between the third upright plate 31 and the fourth upright plate 32.

[0032] In the specific configuration, an inclined plate 37 is provided between the second horizontal plate 33 and the fourth vertical plate 32. The distance between the lower side of the inclined plate 37 and the third vertical plate 31 is smaller than the distance between the upper side of the inclined plate 37 and the third vertical plate 31. The lower side of the inclined plate 37 is connected to the second horizontal plate 33, and the upper side is connected to the fourth vertical plate 32, reducing the width of the second horizontal plate 33 and facilitating the downward insertion of the second U-shaped plate 30 into the first U-shaped plate 10. A rubber strip 15 is provided on the first horizontal plate 13. The bottom of the rubber strip 15 is fixedly connected to the top surface of the first horizontal plate 13, and the side is fixedly connected to the side wall of the first vertical plate 11. After the second U-shaped plate 30 is inserted into the first U-shaped plate 10, the rubber strip 15 abuts against the inclined plate 37, increasing the sealing effect.

[0033] The working principle of the anti-grout leakage structure of the steel truss floor deck in this embodiment is as follows: When installing two adjacent floor deck bodies 1, the second U-shaped plate 30 on one floor deck body 1 is inserted downwards into the first U-shaped plate 10 on the other floor deck body 1. During this process, the locking strip 34 first contacts the top of the first upright plate 11, causing the locking strip 34 to push the fourth upright plate 32 to bend, and the compression spring 35 is compressed. When the locking strip 34 moves to the locking groove 14, the compression spring 35 releases its elasticity, causing the fourth upright plate 32 to return to its original position, and the locking strip 34 is inserted into the locking groove 14. This not only limits the position of the second U-shaped plate 30, but also blocks the concrete grout. At the same time, the first upright plate 11 and the fourth upright plate 32 are in contact, the second upright plate 12 and the third upright plate 31 are in contact, and the rubber strip 15 and the inclined plate 37 are in contact, resulting in a good sealing effect and preventing grout leakage.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
