Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ground crack prevention, and in particular relates to a shock-absorbing floor crack prevention device. Background Art
[0002] Earthquake-resistant structural design is a relatively important structure in building structures. Specifically, building structures, especially large high-rise building structures, need to withstand earthquakes of a certain intensity. That is, when an earthquake of a certain intensity occurs, the building structure can still maintain structural stability during the earthquake, thereby maintaining normal and safe use of the building structure during and after the earthquake.
[0003] Among them, the earthquake resistance of concrete floors is particularly critical for the earthquake resistance of building structures. Specifically, due to the large flatness of concrete floors, and during use, concrete floors with large flat structures are affected by thermal expansion and contraction, and the overall structure of the floor is more easily damaged. In particular, when cracks appear inside the floor structure, it is difficult to fully observe during use.
[0004] Therefore, once an earthquake occurs, the concrete floor with a large plane structure is very likely to crack widely, and the depth of the cracks is often relatively large. Therefore, for high-rise building structures, the safety of use cannot be guaranteed if the ground is severely cracked.
[0005] In the prior art, in order to solve the cracking of the ground, an anchor net structure is often laid in the concrete structure of the ground to increase the structural strength of the concrete ground. However, the anchor net structures disclosed in the prior art are mostly single-layer structural nets. First, the anchoring range is limited, resulting in the upper layer of the concrete ground still cracking in the event of an earthquake. Second, the single-layer anchor net structure is only anchored on a plane, and the concrete ground has a certain thickness, so it is impossible to fully and fully anchor the entire ground structure.
[0006] Finally, because the single-layer anchor net structure accompanies the thermal expansion and contraction of the concrete structure, the structural net and the concrete structure become loose, resulting in reduced stability of the anchor. Therefore, as the concrete floor ages, the concrete structure layer of the ground is prone to cracking once it encounters a ground leveling with a very small amplitude. Utility Model Content

[0047] Embodiment 1
[0048] As Figures 1-5 shown, a shock-absorbing floor crack prevention device includes an upper anchoring steel bar mesh mechanism 2 and a lower anchoring steel bar mesh mechanism 1 disposed below the upper anchoring steel bar mesh mechanism 2. A double-layer anchor mesh formed by the upper anchoring steel bar mesh mechanism 2 and the lower anchoring steel bar mesh mechanism 1 is used to anchor and pull the upper and lower layers of the concrete structure layer during the pouring of the concrete floor, so as to increase its anti-cracking performance.
[0049] Specifically, the upper anchoring steel bar mesh mechanism 2 includes a plurality of upper transverse steel bars 22 and a plurality of upper longitudinal steel bars 21 intersecting with the upper transverse steel bars 22. Similarly, the lower anchoring steel bar mesh mechanism 1 includes a plurality of lower transverse steel bars 12 and a plurality of lower longitudinal steel bars 11 intersecting with the lower transverse steel bars 12.
[0050] In order to anchor and pull the concrete floor to the wall, the ends of the upper transverse steel bars 22 and the lower transverse steel bars 12 are respectively fixedly connected with anchoring end plates 3; a steel bar claw structure is fixedly connected to the anchoring end plates 3, and the steel bar claw structure includes a plurality of first steel bar claws 31 and second steel bar claws 32; the first steel bar claws 31 and the second steel bar claws 32 are anchored in the concrete structure perpendicular to the wall.
[0051] Specifically, the outer ends of the first steel bar claws 31 and the second steel bar claws 32 are integrally formed with hooked portions in a hooked shape; the hooked portions of the first steel bar claws 31 and the second steel bar claws 32 are hooked in opposite directions.
[0052] The above structure realizes that during the pouring process, first, the concrete poured on the steel bar cage with a double-layer structure is vibrated and compacted.
[0053] Subsequently, during the construction of the wall, the first steel bar claws 31 and the second steel bar claws 32 are pulled into the concrete structure of the wall, such as a shear wall. The entire poured steel bar cage structure is anchored and pulled with the wall as an anchor point.
[0054] Under the double-layer network anchorage formed by the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1, the upper and lower layers of the concrete structure on the ground are pulled, so that the overall shape structure of the ground is not easily damaged under the double-layer pulling of the double-layer network structure during both the use process and an earthquake, thereby greatly reducing the risk of its cracking.
[0055] Meanwhile, a number of support structures are welded between the above-mentioned upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1. The support structures include a number of support short bars; both ends of the support short bars are respectively welded on the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1. The top end of the support short bar is welded at the intersection position of the upper transverse steel bar 22 and the upper transverse steel bar 22; the bottom end of the support short bar is welded at the intersection position of the lower transverse steel bar 12 and the lower transverse steel bar 12.
[0056] The upper steel bar network and the lower steel bar network are integrally welded together through the support short bars, so that the double-layer steel bar network forms an integral structure in terms of structure, achieving a sufficient increase in the anti-cracking performance of the concrete structure ground with a certain thickness.
[0057] Embodiment 2
[0058] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, the shock-absorbing floor anti-crack device further includes a fork-shaped tension bar mechanism arranged between the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1, and the fork-shaped tension bar mechanism is used to pull the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1 from the central part. Through the fork-shaped tension bar mechanism, the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1 are tensioned at the hollow position between the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1, further increasing the anti-deformation performance of the upper anchoring steel bar network mechanism 2 and the lower anchoring steel bar network mechanism 1. Specifically, under the thermal expansion and contraction deformation of the concrete structure ground, the steel bar network deforms, and after the deformation of the steel bar network, its anchoring performance decreases, resulting in a reduction in the structural stability of the concrete ground and making it more prone to cracking.
[0059] Specifically, the fork-shaped tension bar mechanism includes an inclined first long diagonal bar 51; both ends of the first long diagonal bar 51 are welded on the support short bars 4 located at diagonal positions; the fork-shaped tension bar mechanism further includes an inclined second long diagonal bar 52; both ends of the second long diagonal bar 52 are welded on the support short bars located at diagonal positions. Meanwhile, the first long diagonal bar 51 and the second long diagonal bar 52 are arranged in a cross manner; the cross position of the first long diagonal bar 51 and the second long diagonal bar 52 is located at the midpoint position of the first long diagonal bar and the second long diagonal bar.
[0060] Embodiment 3
[0061] As Figures 1-5As shown in the figure, on the basis of the structure of Embodiment 2, the shock-absorbing floor anti-crack device further includes a vertical hook bar structure welded to the top of the upper anchoring steel bar mesh mechanism 2 and the bottom of the lower anchoring steel bar mesh mechanism 1. The vertical hook bar structure includes a number of first vertical hook bars and second vertical hook bars that are vertically welded; the bending directions of the first vertical hook bars and the second vertical hook bars are opposite to each other.
[0062] Through the first vertical hook bars 61 (bent to the right) and the second vertical hook bars 62 (bent to the left) distributed at the top of the upper anchoring steel bar mesh mechanism 2 and the bottom of the lower anchoring steel bar mesh mechanism 1, the upper and lower anchoring is realized at the thickness position of the concrete floor structure layer. On the one hand, the wrapping force between the steel bar mesh structure and the concrete is increased, and the stability is improved. Secondly, the concrete thickness structure is anchored, further improving its anti-cracking performance.
[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
