Abstract
Description
Technical Field
[0001] This utility model relates to the field of truss construction technology, and in particular to a steel truss floor deck construction component. Background Technology
[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. The steel truss is prefabricated in the back-end processing yard. On-site construction requires first fixing the profiled sheet to the steel beam with studs, then placing and binding the steel truss, and finally pouring concrete after acceptance.
[0003] Publication number CN213926973U, entitled "A Detachable Steel Truss Floor Decking Support Component and the Floor Decking," discloses: a rigid support plate, a first base support, and a second base support; the main body of the rigid support plate is a strip-shaped connecting plate, on which two mirror-symmetrical fasteners are provided, each with outward-facing steel bar slots on its side; the bottom of the strip-shaped connecting plate has two connecting parts, which are fixedly connected to the first and second base supports respectively; both the first and second base supports are made of non-metallic material, and each has threaded holes at its bottom for screwing in fixing screws, with the bottom surfaces of the first and second base supports flush. This utility model enables rapid fixing of the steel truss on the bottom formwork during the construction of the steel truss floor deck, and can also be easily disassembled after construction. Furthermore, because the base supports are made of non-metallic material, corrosion at the contact points with concrete is avoided, thus improving the lifespan of the floor deck.
[0004] The aforementioned disclosed content can be easily disassembled after construction. However, in the current steel truss floor decking, the components that fix the steel truss are structurally fixed and basically integrated during construction, making it impossible to adjust the support height and adjust the height of the floor decking during installation. Utility Model Content
[0005] This utility model discloses a construction component for steel truss floor decking, aiming to solve the technical problem that in the current construction process of steel truss floor decking, the components for fixing the steel truss are structurally fixed and basically integrated, making it impossible to adjust their support height and thus adjust the height of the floor decking during installation.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A steel truss floor decking construction component includes an upper support plate and a lower support plate. The upper support plate and the lower support plate are both horizontally arranged and interlaced. A connecting bar is provided between the upper support plate and the lower support plate. The top end of the connecting bar passes through the upper support plate and is limited and connected to it by a height adjustment device. The height adjustment device includes an insert plate provided at the end of the upper support plate. Multiple strip grooves are respectively opened on the side of the connecting bar from top to bottom. The end of the insert plate extends into the upper support plate and is engaged with one of the strip grooves. The top end of the lower support plate is inserted into the connecting bar and is engaged with it by a engaging device.
[0008] In a preferred embodiment, the lower surface of the upper support plate is provided with a groove that extends through its upper surface, the bottom end of the connecting rib passes through the groove and is slidably connected to the upper support plate, and the end of the upper support plate is provided with a slot that matches the insert plate.
[0009] By setting a sliding groove, the bottom end of the connecting rib passes through the upper support plate through the sliding groove, and the end of the upper support plate is provided with a slot that matches the insert plate, so that they can be easily connected and disassembled.
[0010] In a preferred embodiment, the end face of the slot is fixedly connected to a tube and has a limiting hole. The end of the insert plate is fixedly connected to a pin that mates with the limiting hole and has a first insertion hole that mates with the tube. The end of the insert plate is provided with a bolt. The end of the bolt is inserted into the first insertion hole and extends into the tube. The bolt is threadedly connected to the tube.
[0011] By setting up the insertion tube, limiting hole, pin, and first insertion hole, during installation, the height of the connecting rib is adjusted so that the slot and the strip groove are at the same level. The insertion plate is then inserted into the slot and the strip groove until the insertion tube is inserted into the first insertion hole and the pin is inserted into the limiting hole to position the insertion plate. Then, the bolts are tightened to fix the insertion plate on the upper support plate to prevent the insertion plate from sliding off in the slot and the strip groove.
[0012] In a preferred embodiment, the lower support plate includes a support plate, a vertical plate is integrally connected to the end of the upper surface of the support plate, a sliding hole is provided at the bottom end of the connecting rib, and the top end of the vertical plate is inserted into the connecting rib through the sliding hole.
[0013] By setting sliding holes, the top of the vertical plate can be inserted into the connecting rib through the sliding holes, so as to achieve convenient connection between the connecting rib and the lower support plate.
[0014] In a preferred embodiment, the side of the connecting rib is provided with a connecting hole communicating with the sliding hole, and the inner wall of the connecting hole and the side of the vertical plate are provided with limit grooves. The snap-fit device includes a limit pin that is slidably inserted into the limit groove. The inner wall of the sliding hole is fixedly connected with a limit post extending into the limit groove. The end of the limit pin is provided with a third insertion hole that cooperates with the limit post.
[0015] By setting a connection hole, the inside of the sliding hole can be observed through the connection hole. After inserting the vertical plate into the sliding hole, the inner wall of the connection hole and the limiting groove opened on the side of the vertical plate are aligned by observing at the connection hole. Then, the limiting pin is inserted to realize the convenient limiting connection between the connecting rib and the lower support plate. The third insertion hole and the limiting post are used together to position the limiting pin.
[0016] As can be seen from the above, the steel truss floor deck construction component provided by this utility model has the following technical effects.
[0017] Firstly, by setting up an upper support plate and a lower support plate, and connecting ribs between the upper support plate and the lower support plate, the upper support plate and the connecting ribs are engaged through the cooperation of strip grooves and insert plates. There are multiple strip grooves from top to bottom, so when engaging the upper support plate and the connecting ribs, only the strip groove that mates with the insert plate needs to be changed to change the height of the bottom end of the connecting rib. The lower support plate is limited and connected to the bottom of the connecting rib, so that the height of the lower support plate can be adjusted accordingly, thereby adjusting the support height of the floor deck during installation.
[0018] Secondly, by setting up upper support plates and lower support plates, and connecting ribs between the upper support plates and lower support plates, the upper support plates and connecting ribs are snapped together by the cooperation of strip grooves and insert plates, and the lower support plates and connecting ribs are limited by snap-fit devices. This allows the entire device to be disassembled and transported during transportation, avoiding excessive space occupation, reducing the quantity transported in a batch, and allowing for disassembly after installation, which facilitates the removal of the floor deck.
