Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a steel truss floor deck frame structure that does not require tying and its construction method. Background Technology

[0002] Floor decking is widely used in steel structure buildings such as steel structure factories, cement warehouses, airport terminals, and railway stations. Floor decking consists of a truss and a bottom formwork, with the bottom formwork fixed to the truss. The steel truss floor decking frame requires several steel wires to be wrapped and secured during installation, a time-consuming and labor-intensive method. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a steel truss floor deck frame structure and its construction method that do not require tying are provided to solve the problem of time-consuming and labor-intensive construction of existing steel truss floor deck frames.

[0004] To achieve the above objectives, a steel truss floor decking frame structure without tying is provided, comprising:

[0005] Multiple supports arranged in a row, each support unit comprising two support units and an arc-shaped connecting rod. Each support unit comprises two inclined struts and an elastic connecting rod. The two ends of the elastic connecting rod are respectively connected to the upper ends of the two struts. The distance between the two struts gradually decreases from bottom to top. A first locking rod is formed at the upper end of one strut. A longitudinal channel is formed between the first locking rod and the elastic connecting rod. The arc-shaped connecting rod is connected between the lower ends of the struts of the two support units. The inner arc surfaces of the two arc-shaped connecting rods on the two support units are arranged opposite each other.

[0006] The upper longitudinal reinforcement is movably inserted into the longitudinal ducts of a row of supports;

[0007] The upper horizontal rib has a second locking rod formed on one side of the elastic connecting rod. A transverse channel is formed between the second locking rod and the upper longitudinal rib. The upper horizontal rib can be movably inserted into the transverse channel corresponding to the position of the multi-row support.

[0008] A multi-row limiting assembly, the limiting assembly including two opposing upright plates, the upright plates being mounted on a bottom template, and the upper parts of the two upright plates extending in opposite directions to form baffles;

[0009] The lower longitudinal rib is provided below the two baffles of each row of limiting components. A row of brackets is provided between two adjacent rows of limiting components. The arc-shaped connecting rods on opposite sides of the row of brackets are provided on the inner side of the upright plate and supported by the lower longitudinal rib. The support unit of the other row of brackets is provided between the two upright plates of each row of limiting components after compression. The arc-shaped connecting rod on one side of the other row of brackets presses against the inner side of the upright plate and is supported by the arc-shaped connecting rod of the row of brackets. After the support unit is compressed, the first locking rod flips upward to lock the upper longitudinal rib in the longitudinal channel and lock the upper transverse rib in the transverse channel.

[0010] Furthermore, the first locking rod is arc-shaped.

[0011] Furthermore, the elastic link is arc-shaped, and the inner arc surface of the elastic link is arranged opposite to the inner arc surface of the first locking rod.

[0012] Furthermore, the second locking rod is arc-shaped.

[0013] This invention provides a construction method for a steel truss floor slab frame structure that does not require tying, comprising the following steps:

[0014] Install multiple rows of limiting components on the bottom template;

[0015] Multiple rows of supports are provided on the bottom template, such that one row of supports is located between two adjacent rows of limiting components, and the support unit of the other row of supports is located between the two upright plates of one row of limiting components;

[0016] Upper longitudinal reinforcement bars can be movably inserted into the longitudinal channels of each row of supports;

[0017] Upper-layer horizontal ribs can be movably inserted into the transverse channels corresponding to the positions of multiple rows of supports;

[0018] A lower longitudinal rib is provided below the two baffles of each row of limiting components;

[0019] The arc-shaped connecting rods on opposite sides of the row of supports are set on the inner side of the upright plate and supported by the lower longitudinal reinforcement.

[0020] The support unit of the other row of brackets is squeezed so that the arc-shaped connecting rod on one side of the other row of brackets presses against the inner side of the upright plate and is supported by the arc-shaped connecting rod of the first row of brackets. The first locking rod flips upward to lock the upper longitudinal rib in the longitudinal channel and lock the upper transverse rib in the transverse channel to avoid wire binding.

[0021] The beneficial effects of this invention are as follows: The steel truss floor decking frame structure of this invention, which does not require binding, places the upper longitudinal reinforcement between the elastic connecting rod and the first locking rod, then places the upper transverse reinforcement between the upper longitudinal reinforcement and the second locking rod, and places the lower longitudinal reinforcement inside the limiting component. At this time, the support rods on both sides of the squeeze bracket cause the elastic connecting rod to bend and deform, so that the arc-shaped connecting rod is inserted below the lower longitudinal reinforcement. The limiting component, the support rod, and the elastic force of the bent and deformed elastic connecting rod hold the lower longitudinal reinforcement in place. At the same time, because the support rods on both sides of the squeeze bracket cause the elastic connecting rod to bend and deform, the first locking rod on the surface of the support rod will rotate upward, thereby squeezing and fixing the upper longitudinal reinforcement and the upper transverse reinforcement. This method of fixing the frame is more convenient and can be completed without the need to wrap steel wire, thus improving the construction efficiency of the steel truss floor decking.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Reference Figures 1 to 3 As shown, the present invention provides a steel truss floor deck frame structure that does not require binding, comprising: a support 1, an upper longitudinal bar 2, an upper transverse bar 3, a limiting component 4, and a lower longitudinal bar 5.

[0029] There are multiple brackets 1. Multiple brackets 1 are arranged in a row.

[0030] For details, please refer to Figure 3 As shown, the bracket 1 includes two support units and an arc-shaped connecting rod 12. The arc-shaped connecting rod connects the two support units.

[0031] Each support unit includes a strut 111 and a flexible connecting rod 112. Each support unit is equipped with two struts and two flexible connecting rods.

[0032] Two support rods 111 are inclined. The distance between the two support rods 111 gradually decreases from bottom to top. The two ends of the elastic connecting rod 112 are connected to the upper ends of the two support rods 111 respectively. The arc-shaped connecting rod 12 is connected between the lower ends of the support rods 111 of the two support units. The inner arc surfaces of the two arc-shaped connecting rods 12 on the two support units are arranged opposite each other.

[0033] A first locking rod 113 is formed at the upper end of a support rod 111. A longitudinal channel is formed between the first locking rod 113 and the elastic connecting rod 112.

[0034] The upper longitudinal reinforcement 2 is movably inserted into the longitudinal duct of a row of supports 1.

[0035] A second locking rod 114 is formed on one side of the elastic connecting rod 112. A transverse channel is formed between the second locking rod 114 and the upper longitudinal rib 2. The transverse channel is perpendicular to the longitudinal channel. The upper transverse rib 3 is movably inserted into the transverse channel corresponding to the position of the multi-row support 1.

[0036] In this embodiment, the first locking rod 113 is arc-shaped. The elastic connecting rod 112 is arc-shaped, and the inner arc surface of the elastic connecting rod 112 is disposed opposite to the inner arc surface of the first locking rod 113.

[0037] As a preferred embodiment, the second locking rod 114 is arc-shaped.

[0038] The limiting components 4 are arranged in multiple rows. The number of rows of limiting components is half the number of rows of the bracket. For details, please refer to [link / reference]. Figure 2 As shown, the limiting component 4 includes two opposing upright plates 41. The upright plates 41 are mounted on the bottom template. The upper parts of the two upright plates 41 extend opposite each other to form baffles 42.

[0039] A lower longitudinal rib 5 is provided below the two baffles 42 of each row of limit components 4.

[0040] A row of brackets 1 is positioned between two adjacent rows of limiting components 4. The arc-shaped connecting rods 12 on opposite sides of the row of brackets 1 are positioned on the inner side of the upright plate 41 and supported by the lower longitudinal reinforcement 5.

[0041] The support unit of the other row of brackets 1 is positioned between the two upright plates 41 of each row of limiting components 4 after being compressed. The distance between the two upright plate brackets of the limiting components is less than the distance between the lower ends of the two struts of the support unit. In this embodiment, the compression of the support unit means that the lower ends of the two struts of the support unit move closer to each other. Through the deformation of the elastic link, the distance between the lower ends of the two struts of the support unit is less than the distance between the two baffles of the limiting component, thereby allowing the bracket to be positioned between the two upright plates of the limiting component. The arc-shaped link 12 on one side of the other row of brackets 1 presses against the inner side of the upright plate 41 and is supported by the arc-shaped link 12 of the other row of brackets 1. Using the rebound force of the elastic link, the lower ends of the two struts of the support unit are pushed outward and upward, so that the arc-shaped link 12 on one side of the other row of brackets 1 presses against the inner side of the upright plate 41 and is supported by the arc-shaped link 12 of the other row of brackets 1.

[0042] After the support unit is compressed, the elastic link bends, and the first locking rod 113 flips upward, so the diameter of the longitudinal channel is reduced to lock the upper longitudinal rib 2 in the longitudinal channel and the upper transverse rib 3 in the transverse channel (by lifting the upper longitudinal rib, the diameter of the transverse channel is reduced, so that the upper transverse rib is locked in the transverse channel).

[0043] This invention provides a construction method for a steel truss floor slab frame structure that does not require tying, comprising the following steps:

[0044] S1. Install multiple rows of limiting components 4 on the bottom template.

[0045] S2. Multiple rows of brackets 1 are set on the bottom template, such that one row of brackets 1 is set between two adjacent rows of limiting components 4, and the support unit of another row of brackets 1 is set between the two upright plates 41 of one row of limiting components 4.

[0046] S3. Upper longitudinal reinforcement 2 is movably inserted into the longitudinal holes of each row of supports 1.

[0047] S4. The upper horizontal reinforcement 3 is movably inserted into the transverse channel corresponding to the position of the multi-row support 1.

[0048] S5. A lower longitudinal rib 5 is provided below the two baffles 42 of each row of limiting components 4.

[0049] S6. Arrange the arc-shaped connecting rods 12 on the opposite sides of a row of brackets 1 on the inner side of the upright plate 41 and support them on the lower longitudinal reinforcement 5.

[0050] S7. Press the support unit of the other row of brackets 1 so that the arc-shaped connecting rod 12 on one side of the other row of brackets 1 presses against the inner side of the upright plate 41 and is supported by the arc-shaped connecting rod 12 of the row of brackets 1. The first locking rod 113 flips upward to lock the upper longitudinal rib 2 in the longitudinal channel and lock the upper transverse rib 3 in the transverse channel to avoid wire binding.

[0051] The tie-free steel truss floor decking frame structure of the present invention includes upper longitudinal reinforcement. Multiple upper transverse reinforcements are provided above the upper longitudinal reinforcement.

[0052] The support frame has lower longitudinal ribs on both sides. Several limiting components are located on one side of each lower longitudinal rib. The upper longitudinal rib is placed between the elastic connecting rod and the first locking rod. Then, the upper transverse rib is placed between the upper longitudinal rib and the second locking rod. The lower longitudinal rib is placed inside the two upright plates of the limiting components. At this point, the support rods on both sides of the support frame are compressed, causing the elastic connecting rod to bend and deform, allowing the arc-shaped connecting rod to insert below the lower longitudinal rib. This, combined with the limiting components, the support rods, and the elastic force from the bending deformation of the elastic connecting rods, holds the lower longitudinal rib in place. Simultaneously, due to the bending deformation of the elastic connecting rods caused by the compression of the support rods on both sides of the support frame, the first locking rod on the surface of the support rod rotates upwards, thereby compressing and fixing the upper longitudinal and transverse ribs. This method of fixing the frame is more convenient and eliminates the need for winding steel wire.

[0053] The support frame includes a support unit and an arc-shaped connecting rod. The support unit includes an elastic connecting rod, a second locking rod, a first locking rod, and a strut. Both ends of the elastic connecting rod are fixedly equipped with struts, one end of which is fixedly connected to the arc-shaped connecting rod.

[0054] A first locking rod is fixedly installed on the surface of the strut. A second locking rod is fixedly installed at the upper end of the elastic connecting rod.

[0055] The upper longitudinal rib is located inside the space between the elastic connecting rod and the first locking rod. The upper transverse rib is located inside the space between the second locking rod and the first locking rod.

[0056] The limiting component is an L-shaped limiting block, and the lower longitudinal rib and the arc-shaped connecting rod are both located inside the limiting component.

[0057] During construction, the upper longitudinal reinforcement is placed between the elastic connecting rod and the first locking rod, and then the upper transverse reinforcement is placed between the upper longitudinal reinforcement and the second locking rod.

[0058] The lower longitudinal rib is placed inside the limiting component. At this time, the support rods on both sides of the squeeze bracket cause the elastic connecting rod to bend and deform, so that the arc-shaped connecting rod is inserted below the lower longitudinal rib. The limiting component, the support rod, and the elastic force of the bent and deformed elastic connecting rod hold the lower longitudinal rib in place. At the same time, because the support rods on both sides of the squeeze bracket cause the elastic connecting rod to bend and deform, the first locking rod on the surface of the support rod will rotate upward, thereby squeezing and fixing the upper longitudinal rib and the upper transverse rib. This method of fixing the frame is more convenient and can be completed without the need to wrap steel wire.

[0059] The present invention relates to a steel truss floor decking frame structure that does not require binding. By placing the upper longitudinal reinforcement between the elastic connecting rod and the first locking rod, and then placing the upper transverse reinforcement between the upper longitudinal reinforcement and the second locking rod, and placing the lower longitudinal reinforcement inside the limiting component, the support rods on both sides of the support are compressed, causing the elastic connecting rod to bend and deform, so that the arc-shaped connecting rod is inserted below the lower longitudinal reinforcement. The limiting component, the support rod, and the elastic force of the bent and deformed elastic connecting rod press against the lower longitudinal reinforcement. At the same time, because the support rods on both sides of the support are compressed, the elastic connecting rod bends and deforms, and the first locking rod on the surface of the support rod rotates upward, thereby compressing and fixing the upper longitudinal reinforcement and the upper transverse reinforcement. This method of fixing the frame is more convenient and can be completed without the need to wrap steel wire, thus improving the construction efficiency of the steel truss floor decking.
