At the same time, since the struts on both sides of the bracket are squeezed to bend and deform the elastic connecting rod, the first locking rod on the surface of the strut will rotate upward, thereby squeezing the upper longitudinal reinforcement and the upper transverse reinforcement above for fixing. This method of fixing the skeleton is more convenient and can be completed without winding steel wire, thereby improving the construction efficiency of the steel frame transverse reinforcement floor deck.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Reference Figures 1 to 3 As shown, the present invention provides a binding-free steel truss floor deck skeleton structure, including: a bracket 1, an upper longitudinal reinforcement 2, an upper transverse reinforcement 3, a limiting component 4, and a lower longitudinal reinforcement 5.

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

[0030] For details, see Figure 3 As shown, the bracket 1 includes two supporting units and an arc-shaped connecting rod 12. The arc-shaped connecting rod is connected to the two supporting units.

[0031] Each support unit includes a support rod 111 and an elastic connecting rod 112. Each support unit is configured with two support rods and two elastic connecting rods.

[0032] The two support rods 111 are arranged at an angle. The distance between the two support rods 111 gradually decreases from bottom to top. The two ends of the elastic connecting rod 112 are respectively connected to the upper ends of the two support rods 111. The arc connecting rod 12 is connected between the lower ends of the support rods 111 of the two supporting units. The inner arc surfaces of the two arc connecting rods 12 on the two supporting units are arranged opposite to 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 ribs 2 are movably inserted into the longitudinal channels of a row of brackets 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 arranged perpendicular to the longitudinal channel. The upper transverse rib 3 can be movably inserted into the transverse channel corresponding to the position of the multiple rows of brackets 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 arranged opposite to the inner arc surface of the first locking rod 113 .

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

[0038] The number of the limiting components 4 is multiple rows. The number of rows of the limiting components is half the number of rows of the brackets. Figure 2 As shown, the limiting assembly 4 includes two vertical plates 41 arranged opposite to each other. The vertical plates 41 are installed on the bottom template. The upper parts of the two vertical plates 41 extend oppositely to form baffles 42.

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

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

[0041] After being squeezed, the support unit of the other row of brackets 1 is arranged between the two vertical plates 41 of each row of limit assemblies 4. The distance between the two vertical plate brackets of a row of limit assemblies is smaller than the distance between the lower ends of the two struts of the support unit. In this embodiment, the squeezing of the support unit refers to the lower ends of the two struts of the support unit approaching each other, and through the deformation of the elastic connecting rod, the distance between the lower ends of the two struts of the support unit is smaller than the distance between the two baffles of the limit assembly, so that the bracket can be arranged between the two vertical plates of the limit assembly. The arc-shaped connecting rod 12 on one side of the other row of brackets 1 is pressed against the inner side of the vertical plate 41 and supported by the arc-shaped connecting rod 12 of the one row of brackets 1. By utilizing the rebound force of the elastic connecting rod, the lower ends of the two struts of the support unit are pushed outward and upward, so that the arc-shaped connecting rod 12 on one side of the other row of brackets 1 is pressed against the inner side of the vertical plate 41 and supported by the arc-shaped connecting rod 12 of the one row of brackets 1.

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

[0043] The present invention provides a construction method for a binding-free steel truss floor deck skeleton structure, comprising the following steps:

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

[0045] S2. Arrange multiple rows of brackets 1 on the bottom template, so that one row of brackets 1 is arranged between two adjacent rows of limiting components 4, and the supporting units of another row of brackets 1 are arranged between two vertical plates 41 of one row of limiting components 4.

[0046] S3. The upper longitudinal reinforcement 2 is movably inserted into the longitudinal channel of each row of brackets 1.

[0047] S4. The upper transverse ribs 3 are movably inserted into the transverse holes corresponding to the positions of the multiple rows of brackets 1 .

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

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

[0050] S7. Squeeze the supporting unit of another row of brackets 1 so that the arc-shaped connecting rod 12 on one side of the other row of brackets 1 is pressed against the inner side of the vertical plate 41 and supported on the arc-shaped connecting rod 12 of one row of brackets 1. The first locking rod 113 flips upward to lock the upper longitudinal reinforcement 2 in the longitudinal channel, and locks the upper transverse reinforcement 3 in the transverse channel to avoid wire binding.

[0051] The binding-free steel bar truss floor slab skeleton structure of the present invention comprises upper longitudinal bars, and a plurality of upper transverse bars are arranged above the upper longitudinal bars.

[0052] Lower longitudinal ribs are provided on both sides of the bracket. Several limit assemblies are provided on one side of the lower longitudinal ribs. The upper longitudinal ribs are placed between the elastic connecting rod and the first locking rod. Then the upper transverse ribs are placed between the upper longitudinal ribs and the second locking rod. The lower longitudinal ribs are placed on the inner side of the two vertical plates of the limit assemblies. At this time, the struts on both sides of the bracket are squeezed to bend and deform the elastic connecting rod, so that the arc-shaped connecting rod is inserted under the lower longitudinal ribs. The limit assemblies, struts and the elastic force of the bending and deformation of the elastic connecting rod support the lower longitudinal ribs. At the same time, since the struts on both sides of the bracket are squeezed to bend and deform the elastic connecting rod, the first locking rod on the surface of the strut will rotate upward, thereby squeezing the upper longitudinal ribs and the upper transverse ribs above for fixing. This method is more convenient for fixing the skeleton and can be completed by winding steel wire.

[0053] The bracket 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 support rod. Both ends of the elastic connecting rod are fixed with support rods, and one end of the support rod is fixedly connected to the arc-shaped connecting rod.

[0054] A first locking rod is fixedly arranged on the surface of the support rod, and a second locking rod is fixedly arranged on the upper end of the elastic connecting rod.

[0055] The upper longitudinal ribs are arranged on the inner side between the elastic connecting rod and the first locking rod. The upper transverse ribs are arranged on the inner side between the second locking rod and the first locking rod.

[0056] The limiting component is an L-shaped limiting block, and the lower longitudinal reinforcement and the arc-shaped connecting rod are both arranged on the inner side of 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] Place the lower longitudinal reinforcement on the inner side of the limiting assembly. At this time, squeeze the struts on both sides of the bracket to make the elastic connecting rod bend and deform, so that the arc-shaped connecting rod is inserted under the lower longitudinal reinforcement. Cooperate with the limiting assembly, the struts and the elastic force of the bending and deformation of the elastic connecting rod to support the lower longitudinal reinforcement. At the same time, since the struts on both sides of the bracket are squeezed to make the elastic connecting rod bend and deform, the first locking rod on the surface of the strut will rotate upward, thereby squeezing the upper longitudinal reinforcement and the upper transverse reinforcement above to fix them. This method is more convenient to fix the skeleton and can be completed without winding steel wire.

[0059] The binding-free steel truss floor deck skeleton structure of the present invention is achieved by placing the upper longitudinal reinforcement between the elastic connecting rod and the first locking rod, then placing the upper transverse reinforcement between the upper longitudinal reinforcement and the second locking rod, and placing the lower longitudinal reinforcement on the inner side of the limiting assembly. At this time, the support rods on both sides of the bracket are squeezed to bend and deform the elastic connecting rod, so that the arc connecting rod is inserted under the lower longitudinal reinforcement, and the lower longitudinal reinforcement is supported by the elastic force of the limiting assembly, the support rod and the bending and deformation of the elastic connecting rod. At the same time, since the support rods on both sides of the bracket are squeezed to bend and deform the elastic connecting rod, the first locking rod on the surface of the support rod will rotate upward, thereby squeezing the upper longitudinal reinforcement and the upper transverse reinforcement above for fixation. This method of fixing the skeleton is more convenient and can be completed without winding steel wire, thereby improving the construction efficiency of the steel frame transverse reinforcement floor deck.

Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
