Referring to fig. 2, an embodiment of the present invention provides a single-sided slab concrete structure including a positioning plate 100, a hooking member 200, a longitudinal bar group 300, tie bars 400, and a concrete casting (not shown). The hooking member 200 is coupled to one side of the positioning plate 100 in the third direction OZ. The longitudinal bar group 300 comprises at least two first longitudinal bars 310 arranged in the first direction OX and at least two second longitudinal bars 320 arranged in the second direction OY, the longitudinal bar group 300 being located on the side of the hook joint 200 facing away from the positioning plate. Specifically, the first direction OX and the second direction OY form a certain angle, wherein the certain angle refers to any angle between 0 ° and 180 °, the third direction OZ is perpendicular to the first direction OX and perpendicular to the second direction OY, in this embodiment, the first direction OX, the second direction OY and the third direction OZ are perpendicular to each other, where the third direction OZ is defined as a vertical direction, the hook 200 is located above the positioning plate 100, and the longitudinal rib group 300 is located above the hook 200. In actual installation, the first longitudinal ribs 310 and the second longitudinal ribs 320 are spaced from the hook members 200, and after the positioning plate 100 is installed, the two sides of the positioning plate 100 need to be erected with supporting frames, and then the first longitudinal ribs 310 and the second longitudinal ribs 320 are erected on the supporting frames.

The lacing wire 400 comprises a lap joint section 410 and two hooking sections 420, wherein one end of each hooking section 420 is respectively connected with the lap joint section 410, the extending direction of each hooking section 420 is along a third direction OZ, the extending direction of the lap joint section 410 is perpendicular to the extending direction of the corresponding hooking section 420, the lap joint sections 410 are lapped on the longitudinal ribs 300, and one end of each hooking section 420, which is away from the lap joint section 410, is hooked with one hooking piece 200. Specifically, the number of the hook members 200 may be an even number, the number of the hook members 200 is 2 times that of the tie bars 400, and two hooking sections 420 in one tie bar 400 are respectively connected with the two hook members 200.

The locating plate 100, the hook connector 200, the longitudinal bar group 300 and the lacing wires 400 are all poured in the concrete pouring body.

Referring to fig. 1, in a general reinforced concrete structure, concrete generally plays a role of compression resistance, and stirrups 10 are connected with a locating plate to form an annular closed structure for play a role of shear resistance.

In this embodiment, by providing the hook members 200 and the tie bars 400, since the lower portion of the hook members 200 is connected with the positioning plate 100, the overlap section 410 of the tie bars 400 overlaps the longitudinal bar groups 300, and each tie bar 400 is correspondingly hooked with the two hook members 200 through the two hooking sections 420, that is, the hook members 200 and the tie bars 400 can connect the positioning plate 100 with the longitudinal bar groups 300, and form a closed structure between the positioning plate 100 and the longitudinal bar groups 300, therefore, the combination of the hook members 200 and the tie bars 400 can replace the stirrups 10 for playing a shearing resistance role between the bottom positioning plate 100 and the top longitudinal bar groups 300. In actual construction, the longitudinal bar group 300 can be installed first, and then the tie bars 400 are lapped on the installed longitudinal bar group 300, that is, the installation and positioning of the longitudinal bar group 300 are not affected by the tie bars 400, so that the operation is convenient.

In some embodiments, the hook 200 includes a connection portion 210 and a hook portion 220 connected in sequence, and the connection portion 210 is connected to the positioning plate 100 at one end thereof in the third direction OZ and connected to the hook portion 220 at the other end thereof. The hook portion 220 may be a U-shaped hook, an L-shaped hook, or a J-shaped hook. When the hook 220 is a U-shaped hook, both ends of the U-shaped hook may be welded to the positioning plate 100 in order to secure tight connection of the hook 220 and the positioning plate 100. In this embodiment, a J-hook is used and the hook connector 200 is a J-peg.

Specifically, the shape of the positioning board 100 may be a triangle, a quadrangle, a pentagon, or the like, and in this embodiment, the shape of the positioning board 100 is a quadrangle, and the number of the hook members 200 may be four, and the four hook members 200 are located on four corners of the positioning board 100, respectively. Through set up hook joint 200 on locating plate 100, lacing wire 400 only need with hook joint 200 hook joint can accomplish the installation of lacing wire 400, convenient operation, the practicality is strong. The bent portion 430 at the lower end of the tie bar 400 is tightly hooked with the J-shaped peg welded to the bottom positioning plate 100, so that tension can be transferred between the tie bar 400 and the J-shaped peg, and the tension is transferred to the positioning plate 100 through the J-shaped peg, thereby forming a stable force transfer structure.

In addition, the hook 200 can be prefabricated on the locating plate 100 in a factory, welding work is not needed on a construction site, the workload of the construction site can be reduced, the construction period can be shortened, and the hook 200 is shorter than the stirrup 10 in height, the occupied space is small, and therefore the transportation cost is low.

Specifically, the connection portion 210 is welded or screwed with the positioning plate 100. The welding mode can be two-side paste welding, one-side paste welding or perforation plug welding. By adopting the connection mode of the hook connector 200 and the locating plate 100 to replace the welding mode of the stirrup 10 and the locating plate 100, a large amount of welding work between the lacing wire 400 and the locating plate 100 can be reduced due to the small contact area of the hook connector 200 and the locating plate 100, and adverse effects of welding residual stress and residual deformation on the locating plate 100 are avoided.

In some embodiments, the hooking section 420 has a bent portion 430, the bent portion 430 being located at an end of the hooking section 420 remote from the overlap section 410, the hooking section 420 being configured to hook with the hooking member 200.

In some embodiments, the number of overlap segments 410 in each tie bar 400 is two, the overlap segments 410 are in one-to-one correspondence with the hooking segments 420, the two overlap segments 410 in each tie bar 400 extend in opposite directions and have overlapping regions 411, and the two overlap segments 410 in each tie bar 400 are fixed in the overlapping regions 411.

In this embodiment, one overlap section 410 and one hooking section 420 are correspondingly connected to form an L-shaped tie, and in the implementation and construction, the overlap sections 410 of the two L-shaped ties need to be fixed in the overlapping area 411 to form one tie 400, and in the fixing, the outer walls of the overlap sections 410 of the two L-shaped ties are first attached, and then the overlap sections 410 of the two L-shaped ties are fixed by binding or welding, so that force can be transferred between the two first L-shaped ties. For convenience of description, one of the two L-shaped tie bars is defined as a first L-shaped tie bar and the other is defined as a second L-shaped tie bar. In this embodiment, for convenience of construction operation, it is preferable that the overlapping section 410 of the first L-shaped lacing wire is fixed with the overlapping section 410 of the second L-shaped lacing wire by means of iron wire binding.

After the positioning plate 100 and the longitudinal bar group 300 are installed, the L-shaped tie bars can be directly lapped on the longitudinal bar group 300. Therefore, in this embodiment, the L-shaped lacing wire is adopted, so that the installation is convenient, the L-shaped lacing wire is only required to be lapped on the longitudinal wire group 300, and then the L-shaped lacing wire is bound or welded.

In other embodiments, the number of overlap sections in each lacing wire is one, and two hooking sections are respectively connected to two ends of one overlap section. The lacing wire is U-shaped lacing wire.

Specifically, the connection form of the L-shaped tie bar in the previous embodiment may be replaced by a U-shaped tie bar, where one U-shaped tie bar is equivalent to a combination of the first L-shaped tie bar and the corresponding second L-shaped tie bar. The U-shaped lacing wire is adopted, and the first L-shaped lacing wire is not required to be connected with the corresponding second L-shaped lacing wire relative to the L-shaped lacing wire, but one U-shaped lacing wire is required to be hooked with the hook parts of the two hook connectors, so that the L-shaped lacing wire is more convenient to operate compared with the L-shaped lacing wire in the hooking process.

In some embodiments, at least two first longitudinal ribs 310 are located on one side of at least two second longitudinal ribs 320 in the third direction OZ.

In this embodiment, at least two first longitudinal ribs 310 refer to all first longitudinal ribs 310, and at least two second longitudinal ribs 320 refer to all second longitudinal ribs 320. In order to ensure the flatness of the lap joint plane of the longitudinal bar groups 300, the first longitudinal bars 310 and the second longitudinal bars 320 form two-layer longitudinal bar structures, wherein each layer of longitudinal bar structure is composed of the first longitudinal bars 310 or each layer of longitudinal bar structure is composed of the second longitudinal bars 320. Specifically, the number of the first longitudinal ribs 310 and the second longitudinal ribs 320 may be two, and the two first longitudinal ribs 310 and the two second longitudinal ribs 320 overlap to form a herringbone frame structure.

In some embodiments, the extending direction of the overlap section 410 may be the second direction OY, specifically, the extending direction of the overlap section 410 is perpendicular to the length direction of the first longitudinal ribs 310, the overlap section overlaps over at least one first longitudinal rib 310 along the second direction OY, and at least one first longitudinal rib 310 is disposed at the intersection position of the overlap section 410 and the hooking section 420.

The lacing wire 400 is lapped on the longitudinal lacing wire group 300, and forms a hoop closed hooping ring by butt joint of the first L-shaped lacing wire and the second L-shaped lacing wire or directly adopting the form of the U-shaped lacing wire 400, and the lacing wire 400 can be clung to the longitudinal lacing wire group 300 by locating at least one first longitudinal lacing wire 310 at the intersection position of the lapping section 410 and the hooking section 420, thereby being beneficial to forming a stable closed structure, fully playing the shearing resistance of the lacing wire 400 and simultaneously ensuring the restraint function of the lacing wire 400 when the longitudinal lacing wire group 300 flexes the outer drum. Specifically, the intersection position of the overlap section 410 and the hooking section 420 of the tie bar 400 may coincide with the intersection position of the first longitudinal bar 310 and the second longitudinal bar 320, so as to facilitate binding the tie bar 400 with the first longitudinal bar 310 and the second longitudinal bar 320 at the same time, thereby further increasing the stability of the structure.

In other embodiments, the extending direction of the overlap segment 410 is the first direction OX, the extending direction of the overlap segment 410 is perpendicular to the length direction of the second longitudinal rib 320, and at least one second longitudinal rib 320 is disposed at the intersection position formed by the overlap segment 410 and the hooking segment 420.

In other embodiments, the number of tie bars 400 is plural, and the tie bars 400 overlap the second longitudinal bars 320 along the first direction OX and overlap the first longitudinal bars 310 along the second direction OY.

In some embodiments, the positioning plate 100 may be a steel plate, and the combined structure of using the steel plate instead of the bottom longitudinal bar set 300 in the conventional reinforced concrete has the following advantages: (1) The bottom steel plate can replace the bottom longitudinal rib group 300 to resist tension, and the steel plate can resist in-plane tension in any direction, so that compared with a structure adopting the bottom longitudinal rib group 300, the steel plate is more flexible in stress and stronger in adaptability, and is particularly suitable for a stress irregular structure; (2) The bottom steel plate can also serve as a template in concrete pouring, so that a formwork supporting link is omitted, and the construction efficiency is greatly improved; (3) The bottom steel plate can avoid exposing cracks of the concrete structure, and the durability of the structure is improved.

In some embodiments, the concrete structure further includes an anchor disposed on the steel plate and located on a side of the steel plate proximate to the tie. In particular, the anchor may be a peg, an anchor bar. The anchoring piece is used for reinforcing the anchoring effect of the steel plate in the concrete casting body, so that the connection between the concrete casting body and the steel plate can be reinforced, and the concrete casting body and the steel plate are prevented from being separated.

An embodiment of the invention provides a building structure, which comprises a plurality of unilateral slab concrete structures connected in sequence.

And because of the lower height of the hook 200, the transportation costs are lower. (if the stirrup 10 is welded directly to the steel plate in the factory, this leads to a significant increase in transportation costs, as a result of the high height of the stirrup 10, compared to the manner in which stirrups 10 are used in the prior art).

S2, installing the prefabricated positioning plate 100 and the hook connector 200 assembly on a construction site.

And S3, constructing a bracket on the combined body, installing the first longitudinal ribs 310 and the second longitudinal ribs 320, and binding the first longitudinal ribs 310 and the second longitudinal ribs 320. Specifically, the first longitudinal ribs 310 and the second longitudinal ribs 320 are vertically erected with each other to form a herringbone frame structure. In actual construction, the longitudinal bar group 300 is installed firstly, and then the tie bars 400 are installed, so that the installation of the longitudinal bar group 300 is not influenced by the tie bars 400, the convenience and the rapidness can be realized, and the accurate positioning of the longitudinal bar group 300 can be realized.

S4, overlapping the lacing wires 400 on the installed longitudinal bar group 300, hooking the hooking section 420 of the lacing wires 400 with the hooking piece 200, and binding the lacing wires 400 with the longitudinal bar group 300. Compared with the mode of welding stirrup 10 in the prior art, a large amount of welding work between stirrup 10 and the steel plate is saved, the adverse effect of welding residual stress and residual deformation on the steel plate is avoided, and the operation is simple and the requirement on construction precision is very low.

S5, pouring concrete to the installed positioning plate 100, the hook connector 200, the longitudinal rib groups 300 and the lacing wires 400.
