Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to a floor deck support connection device. Background Technology

[0002] With the continuous expansion of urban scale, building structures have also developed into diverse forms. Among them, steel structure buildings have advantages such as high degree of industrialization, short construction cycle, energy saving and environmental protection, and therefore have developed rapidly. Steel truss floor decks are generally designed as a formwork-free system. Different specifications of steel truss floor decks are selected based on factors such as structural form, span, floor slab thickness, and construction load. However, there are maximum length regulations for the use of unsupported steel truss floor decks. When the beam spacing is greater than the design length of the floor deck, unsupported operation cannot be achieved.

[0003] Therefore, how to provide a connection device that can extend the application length of floor decking or expand the support range of steel beams is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a floor decking support connection device that can expand the support range of steel beams, enabling floor decking of more sizes to be installed without support. To achieve the above objective, the present invention adopts the following technical solution:

[0005] This invention provides a floor decking support connection device, comprising:

[0006] A support base, one end of which is connected to an extension beam;

[0007] A support tube, which overlaps the end of the extension beam away from the support base;

[0008] A support rod is provided, which is perpendicularly arranged and fixedly connected to the support base. A first clamping block and a second clamping block are slidably connected on the support rod. Two limiting members are also provided on the support rod, and the two limiting members abut against the ends of the first clamping block and the second clamping block that are far apart from each other.

[0009] The diagonal brace has one end connected to the first clamping block or the second clamping block, and the other end connected to the support base. The diagonal brace is a telescopic rod.

[0010] Furthermore, the support rod is provided with threads, and the limiting member is provided with a threaded hole inside, the thread of the threaded hole engaging with the thread on the support rod.

[0011] Furthermore, the inclined support includes a first threaded rod, a second threaded rod, a threaded sleeve, and a stop block. The threads on the first threaded rod and the threads on the second threaded rod have opposite directions of rotation. The threaded sleeve has two sections of threads with opposite directions of rotation inside. The two sections of threads inside the threaded sleeve respectively engage with the threads on the first threaded rod and the second threaded rod. One end of the first threaded rod is threadedly connected to the threaded sleeve, and the other end of the first threaded rod is connected to the first clamping block. One end of the second threaded rod is threadedly connected to the threaded sleeve, and the other end of the second threaded rod is connected to the support base. Two stop blocks are provided, one on the first threaded rod and the other on the second threaded rod, and the other two stop blocks abut against both ends of the threaded sleeve.

[0012] Furthermore, a first connecting seat and a second connecting seat are respectively provided on the side of the first clamping block and the support seat that are close to each other. The first connecting seat and the second connecting seat are provided with through holes. The ends of the first threaded rod and the second threaded rod that are far apart from each other are provided with mounting holes. Connecting components are provided in the mounting holes and the through holes. The first connecting seat and the first threaded rod are connected by the two sets of connecting components, and the second connecting seat and the second threaded rod are respectively connected by the two sets of connecting components.

[0013] Furthermore, the connecting assembly consists of a pin and a pin plate, with the pin inserted into the through hole and the mounting hole, and the pin plate inserted into the connecting hole of the pin.

[0014] Furthermore, the connecting assembly is a bolt and a nut, the bolt being inserted into the through hole and the mounting hole, and the nut abutting against the first connecting seat or the second rotating connection.

[0015] Furthermore, the support base has a groove at one end near the extension beam, and the extension beam is located in the groove and connected to the side wall of the groove.

[0016] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a floor decking support connection device. A first clamping block and a second clamping block connect the support rod and the support seat to the bottom plate of the steel beam. An extension beam extends the length of the steel beam, allowing floor decking with a length less than the distance between two steel beams to be connected to the steel beam. The support rod, diagonal braces, and support seat support the support pipe, thereby supporting the floor decking and ensuring its stability. Once the floor slab concrete is poured and meets the required strength, it can be dismantled, saving labor and allowing for reuse. This avoids damage to the steel beam caused by direct welding. The triangular frame formed by the support rod, diagonal braces, and support seat, through leverage, transfers the load of the floor decking to the support pipe and then to the steel beam, reducing the load on the steel beam.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figure 1-4 This invention discloses a floor decking support connection device, comprising:

[0025] Support base 5, one end of support base 5 is connected to extension beam 15;

[0026] Support tube 3 overlaps at the end of extension beam 15 away from support seat 5;

[0027] Support rod 4 is perpendicularly and fixedly connected to support base 5. A first clamping block 6 and a second clamping block 7 are slidably connected on support rod 4. Two limiting members 8 are also provided on support rod 4. The two limiting members 8 abut against the ends of the first clamping block 6 and the second clamping block 7 that are far away from each other.

[0028] The diagonal brace has one end connected to the first clamping block 6 or the second clamping block 7, and the other end connected to the support base 5. The diagonal brace is a telescopic rod.

[0029] In some embodiments, the support tube 3 overlaps at the end of an adjacent plurality of extension beams 15 away from the support base 5.

[0030] When the length of the floor deck 2 is less than the distance between the two steel beams 1, push the first clamping block 6 and the second clamping block 7, adjust the distance between the first clamping block 6 and the second clamping block 7 so that the ends of the first clamping block 6 and the second clamping block 7 that are close to each other are located on both sides of the bottom plate of the steel beam 1. Push the two limiting pieces 8 so that the two limiting pieces 8 squeeze the ends of the first clamping block 6 and the second clamping block 7 that are far from each other, so that the ends of the first clamping block 6 and the second clamping block 7 that are close to each other abut against the steel beam 1. Connect one end of the diagonal brace to the first clamping block 6. Adjust the length of the diagonal brace. After adjusting the diagonal brace to a suitable length, connect the end of the diagonal brace that is far from the first clamping block 6 to the support base 5. Place the support pipe 3 above the extension beam 15. Lay the floor deck 2 on the support pipe 3 and the steel beam 1 to expand the support range of the steel beam 1, so that more floor deck 2 of a certain length can be laid without support.

[0031] In some embodiments, the first clamping block 6 and the second clamping block 7 are provided with through sliding holes, the support rod 4 is provided with threads, and the limiting member 8 is provided with a threaded hole inside, the threads of the threaded hole cooperating with the threads on the support rod 4.

[0032] When adjusting the positions of the first clamping block 6 and the second clamping block 7, push the first clamping block 6 and the second clamping block 7 to both sides of the bottom plate of the steel beam 1, so that the first clamping block 6 and the second clamping block 7 are in contact with the steel beam 1. At this time, rotate the limiting member 8 so that the limiting member 8 moves along the length direction of the support rod 4 until one limiting member 8 is in contact with the first clamping block 6 and the other limiting member 8 is in contact with the second clamping block 7. Continue to rotate the limiting member 8 so that one limiting member 8 pushes the first clamping block 6 to continue to move downward, thereby causing the first clamping block 6 to press against the upper side of the bottom plate of the steel beam 1. This causes another limiting member 8 to push the second clamping block 7 to continue moving upward, causing the second clamping block 7 to press against the lower side of the base plate of the steel beam 1, stopping the rotation of the limiting member 8. Through the compression between the first clamping block 6 and the second clamping block 7 and the steel beam 1, the support rod 4 is fixed to the base plate of the steel beam 1, thereby fixing the support connection device to the steel beam 1. Through the engagement of the threaded hole on the limiting member 8 with the thread on the support rod 4, the limiting member 8 achieves self-locking, while preventing the first clamping block 6 and the second clamping block 7 from sliding, thus ensuring the support effect on the floor deck 2.

[0033] In some embodiments, the diagonal brace includes a first threaded rod 10, a second threaded rod 13, a threaded sleeve 11, and a stop block 12. The threads on the first threaded rod 10 and the threads on the second threaded rod 13 have opposite directions of rotation. The threaded sleeve 11 has two sections of threads with opposite directions of rotation inside. The two sections of threads inside the threaded sleeve 11 respectively engage with the threads on the first threaded rod 10 and the threads on the second threaded rod 13. One end of the first threaded rod 10 is threadedly connected to the threaded sleeve 11, and the other end of the first threaded rod 10 is connected to the first clamping block 6. The second threaded rod 13... One end of the threaded rod 13 is threadedly connected to the threaded sleeve 11, and the other end of the second threaded rod 13 is connected to the support base 5. Two stops 12 are provided, which are respectively provided on the first threaded rod 10 and the second threaded rod 13. The stops 12 have through threaded holes inside. The threaded holes of the stops 12 on the first threaded rod 10 are engaged with the threads on the first threaded rod 10, and the threaded holes of the stops 12 on the second threaded rod 13 are engaged with the threads on the second threaded rod 13. The two stops 12 abut against the two ends of the threaded sleeve 11 respectively.

[0034] In some embodiments, the thread on the first threaded rod 10 is a forward thread, the thread on the second threaded rod 13 is a reverse thread, and the inside of the threaded sleeve 11 is provided with forward and reverse threads of equal length. The forward and reverse threads inside the threaded sleeve 11 extend to the center of the threaded sleeve 11. The first threaded rod 10 is threaded to the end of the threaded sleeve 11 with the forward thread, and the second threaded rod 13 is threaded to the end of the threaded sleeve 11 with the reverse thread.

[0035] During the installation of the diagonal brace, the threaded sleeve 11 is rotated to simultaneously screw the first threaded rod 10 and the second threaded rod 13 into or out of the threaded sleeve 11, thereby adjusting the length of the diagonal brace. After the diagonal brace is adjusted to a certain length, the first threaded rod 10 is connected to the first clamping block 6, and the second threaded rod 13 is connected to the support base 5 to complete the installation of the diagonal brace. The stop block 12 is rotated to move the two stop blocks 12 to the two ends of the threaded sleeve 11 respectively. The stop blocks 12 are continued to be rotated to squeeze the threaded sleeve 11, thereby preventing the rotation of the threaded sleeve 11.

[0036] In some embodiments, a first connecting seat 9 and a second connecting seat 14 are respectively provided on the side of the first clamping block 6 and the support seat 5 that are close to each other. The first connecting seat 9 and the second connecting seat 14 are provided with through holes. The first threaded rod 10 and the second threaded rod 13 are provided with mounting holes at the ends that are far apart from each other. Connecting components are provided in the mounting holes and the through holes. The first connecting seat 9 and the first threaded rod 10 and the second connecting seat 14 and the second threaded rod 13 are respectively connected by two sets of connecting components.

[0037] In some embodiments, the connecting components are a pin 17 and a pin plate 16, with the pin 17 inserted into a through hole and a mounting hole, and the pin plate 16 inserted into a connecting hole of the pin 17.

[0038] During the process of connecting the first threaded rod 10 and the first clamping block 6, the pin 17 is inserted into the through hole and the mounting hole, and the pin plate 16 is inserted into the connecting hole of the pin 17 to realize the connection between the first threaded rod 10 and the first connecting seat 9, thereby realizing the rotational connection between the first threaded rod 10 and the first clamping block 6.

[0039] During the process of connecting the second threaded rod 13 and the support seat 5, the pin 17 is inserted into the through hole and the mounting hole, and the pin plate 16 is inserted into the connecting hole of the pin 17 to realize the connection between the second threaded rod 13 and the second connecting seat 14, thereby realizing the rotational connection between the second threaded rod 13 and the support seat 5.

[0040] After connecting the two ends of the diagonal brace to the first clamping block 6 and the support seat 5 respectively, rotate the threaded sleeve 11 so that the first threaded rod 10 and the second threaded rod 13 are simultaneously screwed into or out of the threaded sleeve 11, thereby achieving a fine adjustment of the length of the diagonal brace, and thus achieving a fine adjustment of the height of the support seat 5, ensuring the flatness of the support tube 3.

[0041] In some embodiments, the connecting components are bolts and nuts, with the bolts inserted into the through hole and the mounting hole, and the nuts abutting against the first connecting seat 9 or the second connecting seat 14.

[0042] The first threaded rod 10 is fixed to the first connecting seat 9 by the cooperation of bolts and nuts, thereby fixing the first threaded rod 10 to the first clamping block 6.

[0043] The second threaded rod 13 is fixed to the second connecting seat 14 by the cooperation of bolts and nuts, thereby fixing the second threaded rod 13 to the support seat 5.

[0044] The diagonal brace is stably fixed between the first clamping block 6 and the support base 5 by the use of bolts and nuts, ensuring the stability of the support connection mechanism.

[0045] In some embodiments, the support base 5 is provided with a groove at one end near the extension beam 15, and the extension beam 15 is located in the groove and connected to the side wall of the groove.

[0046] In some embodiments, the extension beam 15 is bolted to the sidewall of the groove.

[0047] Once the floor slab concrete pouring is completed and meets the required strength, the supporting connection device will be removed for future use.
