Description

Technical Field

[0001] The utility model relates to a one-way board system of a building structure floor, in particular to a pre-tensioned prestressed double-rib one-way floor board assembly structure. Background Art

[0002] With the decline in population growth rate and the increasing shortage of labor, the application of prefabricated buildings is becoming more and more widespread. The vertical load transmission system of large-span and high-load floors in prefabricated buildings is currently divided into two categories: concrete structure and steel structure. The floor of the concrete structure generally adopts secondary beam + concrete floor slab, or double T plate / large-span prestressed hollow slab. The secondary beam + concrete floor slab method has a long construction period and a large amount of on-site work. It is generally necessary to set up temporary supports and scaffolding, and the construction efficiency is low; the double T plate / large-span prestressed hollow slab structure has a high total height, which affects the house clearance. The back arch is large during the construction process, and cracks are easily generated between the plates due to the continuous stiffness and force characteristics. In addition, cracks will also occur between the prestressed one-way floor panels in the prior art due to inconsistent back arches. Utility Model Content

[0003] The purpose of the utility model is to provide a pre-tensioned prestressed double-rib one-way floor panel assembly structure. The utility model has the characteristics of improving construction efficiency and effectively reducing reverse arch and cracks between panels.

[0004] The technical solution of the utility model is as follows: a prestressed double-rib one-way floor panel assembly structure of a pre-tensioned method, comprising a plurality of double-rib floor panels and superimposed side beams distributed in parallel with the double-rib floor panels, connection notches are arranged on both sides of the top of the double-rib floor panels, and ears are arranged on the superimposed side beams; a first superimposed plate is arranged between adjacent double-rib floor panels, both ends of the first superimposed plate are placed on the connection notches, a second superimposed plate is arranged between the superimposed side beams and the double-rib floor panels, one end of the second superimposed plate is placed on the ears, and the other end of the second superimposed plate is placed on the connection notch.

[0005] In the aforementioned prestressed double-rib one-way floor panel assembly structure, the double-rib floor panel is composed of a prestressed panel and prestressed side ribs, the prestressed side ribs are arranged on both sides of the bottom of the prestressed panel, and the connecting notch is located at the connection between the prestressed panel and the prestressed side ribs.

[0006] In the aforementioned pre-tensioned prestressed double-rib one-way floor panel assembly structure, the end section of the prestressed side rib is rectangular or "T"-shaped.

[0007] In the aforementioned prestressed double-rib one-way floor panel assembly structure, a plurality of transverse steel bars are arranged in the prestressed panel, and first longitudinal steel bars are vertically distributed on the transverse steel bars.

[0008] In the aforementioned pre-tensioned prestressed double-rib one-way floor panel assembly structure, the inner end of the prestressed side rib is provided with a U-shaped steel bar connected to the transverse steel bar, and the second longitudinal steel bar is vertically distributed on the U-shaped steel bar.

[0009] In the aforementioned pre-tensioned prestressed double-rib one-way floor panel assembly structure, a vertical steel bar connected to the transverse steel bar is provided in the inner middle portion of the prestressed side rib, and a third longitudinal steel bar is vertically distributed on the vertical steel bar.

[0010] In the aforementioned prestressed double-rib one-way floor panel assembly structure, the top surface of the prestressed panel is a rough surface, and the prestressed panel is also provided with shear reinforcement, horse stool reinforcement or plane truss reinforcement extending to the prestressed side ribs.

[0011] In the aforementioned pre-tensioned prestressed double-rib one-way floor panel assembly structure, the end of the double-rib floor panel is provided with a connecting web connecting two prestressed side ribs, and the connecting web is connected in parallel to the cantilever of the main beam in a linear connection manner.

[0013] In the aforementioned pre-tensioned prestressed double-rib one-way floor panel assembly structure, a laminated layer is provided on the first laminated plate and the second laminated plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can adjust the height of the double-rib floor panel and the number and arrangement of steel bars according to the span and load-bearing requirements of the floor, which is conducive to meeting the floor load-bearing and house net height requirements under high load and large span conditions, effectively reduces the total height of the structural beams and slabs compared to traditional concrete floors, and significantly reduces the anti-arch value of prestressed double T-plates or hollow slabs.

[0016] The present application designs a new assembly structure, in which a first composite plate is used as a transition section between adjacent prestressed double-rib floor panels, and a one-way second composite plate is set as a transition section between the composite edge beam and the prestressed double-rib floor panels, thereby effectively reducing cracks and solving the problem of cracks caused by inconsistent anti-arch between other prestressed one-way floor panels, and the construction is convenient and quick.

[0017] There is no need to set up secondary beams for floor force transmission. By setting ears on the overlapping side beams, an unsupported construction process can be achieved, effectively improving construction efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example:

[0031] like Figure 1-6 As shown, a prestressed double-rib one-way floor panel assembly structure according to the prestressing method includes a plurality of double-rib floor panels and composite edge beams 5 distributed parallel to the double-rib floor panels, connection notches 3 are provided on both sides of the top of the double-rib floor panels, and ears 51 are provided on the composite edge beams 5; a first composite plate 41 is provided between adjacent double-rib floor panels, and both ends of the first composite plate 41 are placed on the connection notch 3, a second composite plate 42 is provided between the composite edge beams 5 and the double-rib floor panels, one end of the second composite plate 42 is placed on the ear 51, and the other end of the second composite plate 42 is placed on the connection notch 3.

[0032] The installation form of the first composite board 41 and the second composite board 42 makes it unnecessary to set up a secondary beam for floor force transmission. Through the connection gap 3 of the double-rib floor panel and the ear 51 structure of the composite side beam 5, support-free installation construction can be achieved. After the installation is completed, a continuous plate is formed as a whole through the cast-in-place composite layer 7, which effectively improves the construction efficiency; and effectively solves the problem of easy cracking between the plates due to inconsistent anti-arch or discontinuous stiffness of the general prestressed panel 1.

[0033] The utility model has the advantages of simple structure, reduced anti-arch, effective reduction of cracks between plates, high construction efficiency and good economy, and is suitable for various large-span and high-load prefabricated buildings.

[0034] The double-rib floor panel is composed of a prestressed panel 1 and prestressed side ribs 2. The prestressed side ribs 2 are arranged on both sides of the bottom of the prestressed panel 1. The connecting notch 3 is located at the connection between the prestressed panel 1 and the prestressed side ribs 2.

[0035] The end section of the prestressed edge rib 2 is rectangular or T-shaped. The prestressed panel 1 and the prestressed edge rib 2 can be combined in different forms. Figure 5 As shown in AD.

[0036] The prestressed panel 1 is provided with a plurality of transverse steel bars 11 , and first longitudinal steel bars 12 are vertically distributed on the transverse steel bars 11 .

[0037] The inner end of the prestressed side rib 2 is provided with a U-shaped steel bar 21 connected to the transverse steel bar 11, and a second longitudinal steel bar 22 is vertically distributed on the U-shaped steel bar 21. Figure 6 Schematic diagram of the end reinforcement structure of the double-rib floor slab of A.

[0038] The inner middle part of the prestressed edge rib 2 is provided with a vertical steel bar 23 connected to the transverse steel bar 11, and a third longitudinal steel bar 24 is vertically distributed on the vertical steel bar 23. Figure 6 Schematic diagram of the middle reinforcement structure of the double-rib floor panel B.

[0039] Prestressed steel bars or prestressed steel strands are also provided inside the prestressed side ribs 2 .

[0040] The continuity of the arrangement of various stress-bearing steel bars inside the prestressed face plate 1 and the prestressed side ribs 2 achieves high crack resistance requirements and can effectively reduce cracks between panels.

[0041] The top surface of the prestressed panel 1 is a rough surface, and the prestressed panel 1 is further provided with shear reinforcement 13, horse stool reinforcement or plane truss reinforcement extending to the prestressed side rib 2. The shear reinforcement 13 is located at the end of the double-rib floor panel.

[0042] The ends of the double-rib floor panels are provided with connecting webs 6 connecting two prestressed side ribs 2. The connecting webs 6 are connected in parallel to the ears of the main beams 9 in a linear connection manner. The connecting webs 6 convert the end force transmission from the concentrated force of two points into a linear load, increase the range of additional stirrup arrangement of the ears of the main beams 9, and improve the safety of the ears of the main beams.

[0043] The two end caps of the prestressed side rib 2 are vertically connected to the ears or notches on the main beam 9 by point support.

[0044] The first composite board 41 and the second composite board 42 are provided with a composite layer 7. After installation, the composite layer 7 is poured on the first composite board 41 and the second composite board 42 to ensure that the horizontal force can be effectively transmitted to the lateral resistance system.

[0045] When the double-rib one-way floor panel of the utility model is constructed, the construction process is as follows:

[0046] (1) The construction of the lower prefabricated or cast-in-place columns or steel columns is completed, and the elevation, positioning and verticality of the columns are verified;

[0047] (2) Construct the prefabricated or cast-in-place composite side beams 5 of this layer and check the axis dimensions and elevation;

[0048] (3) A hook 8 is provided on the double-rib floor panel, and the prestressed double-rib floor panel of the current layer is hoisted and installed in place according to the plane position;

[0049] (4) hoist the first and second laminated plates 41 and 42 of the current layer and install them in place according to the plane position;

[0050] (5) If there is a superimposed layer 7, install the superimposed layer 7 reinforcement, construct the floor safety guardrail, pour the superimposed layer 7 concrete and maintain it;

[0051] (6) If there is no superimposed layer 7, install floor supports or connectors, install floor construction safety guardrails, pour surface concrete and maintain the surface layer. Construction can also be carried out after the entire building is capped;

[0052] (7) Install prefabricated or cast-in-place columns or steel columns on this floor. Repeat steps (1) to (5) or (6).
