Abstract
Description
Technical Field
[0001] This application relates to the field of prefabricated building floor slabs, and in particular to a load-bearing layer structure for a unitized composite exterior wall. Background Technology
[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components are prefabricated in factories and then transported to the construction site for assembly. Prefabricated construction can significantly accelerate the construction cycle and has wide applications.
[0003] Existing prefabricated building floor slabs consist of concrete walls and reinforcing bars. The reinforcing bars are perpendicular to each other and interlaced. Cement mortar submerges the reinforcing bars and solidifies to form concrete walls. After the cement mortar solidifies, the ends of the reinforcing bars protrude from the concrete walls. Construction workers hoist the floor slabs to connect the reinforcing bars at the ends of the floor slabs, thereby achieving the effect of assembling and forming the building structure.
[0004] The above-mentioned technical solutions have the following drawbacks: the connection of the floor slab is achieved by connecting the ends of the steel bars in the floor slab. When connecting vertical and horizontal floor slabs, other connecting parts need to be set between the floor slabs, which is inefficient and has poor connection stability. Utility Model Content
[0005] To improve the efficiency of floor slab assembly construction, this application provides a load-bearing layer structure for a unitized composite exterior wall.
[0006] The load-bearing layer structure of the unitized composite exterior wall provided in this application adopts the following technical solution:
[0007] A load-bearing layer structure for a unitized composite exterior wall includes side wall panels and horizontal floor slabs. The side wall panels include I-beams, multiple vertical reinforcing bars, and a concrete wall. The multiple vertical reinforcing bars are arranged at equal intervals along the length of the I-beams. Multiple external connection holes are provided on the upper flange of the I-beams. The vertical reinforcing bars are set in the concrete wall, with both ends extending out of the concrete wall. One end of the vertical reinforcing bar is fixed to the lower flange of the I-beam, and the other end is used to insert into the external connection holes of other I-beams. The horizontal floor slab is used to connect to the web of the I-beams.
[0008] By adopting the above technical solution, and by setting I-beams on one side of the side wall panels, when multiple side wall panels are stacked vertically, the vertical steel bars in one side wall panel can be inserted into the I-beams of another side wall panel, thereby enabling two adjacent side wall panels to be stably connected. The horizontal floor slab can be clamped onto one side of the web of the I-beam, thus enabling the I-beam to support the horizontal floor slab. The splicing between the horizontal floor slab and the side wall panels is relatively convenient, which can improve the efficiency of floor slab assembly construction.
[0009] Optionally, the ends of the vertical reinforcing bars are threaded with nuts.
[0010] By adopting the above technical solution, and by setting nuts at the ends of the vertical reinforcing bars, the nuts can abut against the I-beams, thereby improving the connection strength between the vertical reinforcing bars and the I-beams.
[0011] Optionally, the upper flange of the I-beam is provided with multiple internal connecting holes, and two rows of vertical reinforcing bars are provided on the I-beam, which are respectively inserted into the internal connecting holes and the external connecting holes.
[0012] By adopting the above technical solution, by opening internal connection holes in the I-beams, two rows of vertical steel bars can be inserted into the internal connection holes and external connection holes respectively, thereby improving the connection stability between adjacent side wall panels.
[0013] Optionally, the horizontal floor slab includes an outer frame and a floor slab. The outer frame is made of metal materials to form a frame structure. The floor slab is set inside the outer frame. The outer frame has multiple mating holes, and vertical steel bars are used to insert into the inner connection holes and mating holes.
[0014] By adopting the above technical solution, an outer frame is set outside the floor slab, and multiple steel bars are welded and fixed on the outer frame. The steel bars are placed in the floor slab, thereby making the outer frame and the floor slab stably connected. The outer frame can be inserted into the I-beams, so that the I-beams support the horizontal floor slab. By inserting the vertical steel bars into the outer frame, the connection stability between the horizontal floor slab and the side wall slab is further improved, and the probability of the horizontal floor slab slipping on the side wall slab is reduced.
[0015] Optionally, the horizontal floor slab has multiple insertion holes, and insertion rods are installed in the insertion holes. The insertion rods are used to pass through the web of the I-beam and the horizontal floor slab, and nuts are threaded to the ends of the insertion rods.
[0016] By adopting the above technical solution, multiple insertion holes are opened on the horizontal floor slab, allowing the insertion rod to pass through the webs of two I-beams and be inserted into the insertion holes. Nuts are installed at the ends of the insertion rods to ensure that both ends of the insertion rods are tightly connected to the side wall panels, thereby improving the connection stability between the side wall panels and the horizontal floor slab.
[0017] Optionally, the insertion hole includes an upper insertion hole and a lower insertion hole, which are respectively opened on adjacent sides of the horizontal floor slab. The upper insertion hole and the lower insertion hole are perpendicular to each other, and a insertion rod is provided in both the upper insertion hole and the lower insertion hole.
[0018] By adopting the above technical solution, by opening upper and lower insertion holes in the horizontal floor slab, mutually perpendicular insertion rods can be inserted into the horizontal floor slab, so that both ends of the insertion rods can be connected to the side wall panels, and multiple side wall panels can form a rectangular frame and be tightly connected to the horizontal floor slab.
[0019] Optionally, the side wall panel is provided with multiple diagonal bracing components. Each diagonal bracing component includes a tie rod, two bearing seats, and two mounting components. The two ends of the tie rod are fixed to the two bearing seats respectively. Each bearing seat is rotatably connected to a mounting component. One mounting component is connected to the side wall panel, and the other mounting component is connected to the ground.
[0020] By adopting the above technical solution, by setting diagonal bracing members on the side wall panel, the two ends of the diagonal bracing members are fixed to the side wall panel and the ground respectively. When the diagonal bracing members are installed on the side wall panel, the tie rod is set at an angle and provides support for the diagonal bracing members.
[0021] Optionally, a foamed material layer is provided at the edge of the side wall panel and the horizontal floor slab, and the foamed material layer is used to cover the surface of the metal material.
[0022] By adopting the above technical solution, and by setting a foamed material layer on the side wall panels and horizontal floor slabs, construction workers can inject fillers made of epoxy resin and other materials into the gaps between the side wall panels and horizontal floor slabs, thereby covering the surface of the I-beams, vertical steel bars and dowels with the foamed material layer, which reduces the contact between the metal materials and the air, reduces the speed of rusting of the metal materials, and improves the service life of the building.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By setting I-beams on one side of the side wall panels, when multiple side wall panels are stacked vertically, the vertical steel bars in one side wall panel can be inserted into the I-beams of another side wall panel, thereby enabling two adjacent side wall panels to be stably connected. The horizontal floor slab can be clamped onto one side of the web of the I-beam, thus enabling the I-beam to support the horizontal floor slab. The splicing between the horizontal floor slab and the side wall panels is more convenient, which can improve the efficiency of floor slab assembly construction.
[0025] 2. By setting an outer frame outside the floor slab and welding and fixing multiple steel bars on the outer frame, the steel bars are placed in the floor slab, thereby making the outer frame and the floor slab stably connected. The outer frame can be inserted into the I-beams, so that the I-beams support the horizontal floor slab. By inserting the vertical steel bars into the outer frame, the connection stability between the horizontal floor slab and the side wall slab is further improved, and the probability of the horizontal floor slab slipping on the side wall slab is reduced.
[0026] 3. By opening upper and lower insertion holes in the horizontal floor slab, mutually perpendicular insertion rods can be inserted into the horizontal floor slab, so that both ends of the insertion rods can be connected to the side wall panels, and multiple side wall panels can form a rectangular frame and be tightly connected to the horizontal floor slab.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.
[0037] This application discloses a load-bearing layer structure for a unitized composite exterior wall, referring to... Figure 1 , Figure 2 and Figure 3The prefabricated building comprises multiple side wall panels 1 and a horizontal floor slab 2. The side wall panels 1 are vertically arranged, and the horizontal floor slab 2 is horizontally connected to the ends of the side wall panels 1. Each side wall panel 1 includes an I-beam 11, multiple vertical reinforcing bars 12, and a concrete wall 13. The I-beam 11 is horizontally arranged, and the multiple vertical reinforcing bars 12 are spaced apart along the length of the I-beam 11. The vertical reinforcing bars 12 are vertically welded to the I-beam 11, and reinforcing bars perpendicular to the vertical reinforcing bars 12 are welded and fixed between them. Cement mortar submerges the vertical reinforcing bars 12 and solidifies to form the concrete wall 13. The vertical reinforcing bars 12 and the concrete wall 13 form a reinforced concrete structure. When the side wall panels 1 are vertically arranged, the I-beam 11 of the side wall panel 1 is connected to the vertical reinforcing bars 12 of other side wall panels 1, allowing the I-beam 11 to be positioned between two concrete walls 13, thus supporting the concrete walls 13. The horizontal floor slab 2 is connected to the waist of the I-beam 11. The I-beam 11 enhances the structural strength of the prefabricated building and improves construction efficiency.
[0038] Reference Figure 4 An external connecting hole 112 is provided on the upper flange of the I-beam 11. Vertical reinforcing bars 12 are welded to the lower flange of the I-beam 11. The external connecting holes 112 are equidistantly spaced along the length of the I-beam 11. When the side wall panels 1 are arranged vertically, the vertical reinforcing bars 12 of the upper side wall panel 1 can be inserted one-to-one into the external connecting holes 112 of the lower I-beam 11. Construction workers can install nuts at the ends of the vertical reinforcing bars 12 to ensure a stable connection between adjacent side wall panels 1.
[0039] Reference Figure 4 An internal connecting hole 111 is provided on the I-beam 11, and the internal connecting hole 111 is provided on the upper flange of the I-beam 11. The internal connecting holes 111 are provided at equal intervals along the length of the I-beam 11. Two rows of vertical reinforcing bars 12 are connected to the I-beam 11. One row of vertical reinforcing bars 12 is used to insert into the internal connecting hole 111, and the other row of vertical reinforcing bars 12 is used to insert into the external connecting hole 112.
[0040] Reference Figure 7 and Figure 8The horizontal floor slab 2 includes an outer frame 21 and a floor slab 22. The outer frame 21 is a rectangular frame structure formed by splicing metal sheets. Reinforcing bars are installed in the outer frame 21, with the bars arranged perpendicularly and intersecting each other. One end of each reinforcing bar is welded to an outer frame 21. The floor slab 22 is formed by pouring cement mortar, and the cement mortar and reinforcing bars form a reinforced concrete structure. The outer frame 21 is used to fit between the upper and lower flanges of the I-beam 11. Multiple mating holes 211 are provided on the outer frame 21, equidistantly spaced along the extension direction of the outer frame 21. When the outer frame 21 is positioned between the upper and lower flanges of the I-beam 11, vertical reinforcing bars 12 can be inserted into the inner connecting holes 111 and the mating holes 211. The vertical reinforcing bars 12 connect the side wall panel 1 and the horizontal floor slab 2, improving the connection stability between the horizontal floor slab 2 and the side wall panel 1.
[0041] Reference Figure 6 and Figure 7 The horizontal floor slab 2 has multiple insertion holes 23, including upper insertion holes 231 and lower insertion holes 232. The upper insertion holes 231 and lower insertion holes 232 are respectively opened on adjacent two sides of the floor slab 22, and the upper insertion holes 231 and lower insertion holes 232 are perpendicular to each other. The insertion holes 23 can be formed by pre-embedding plastic tubes in the floor slab 22. Insertion rods 24 are provided in the insertion holes 23. When the horizontal floor slab 2 is horizontally set on one side of the I-beam 11, the insertion rods 24 pass through the web of the I-beam 11, the outer frame 21 and the floor slab 22 in sequence. The two ends of the insertion rods 24 extend outside the I-beam 11. By setting nuts at the ends of the insertion rods 24, the connection stability between the horizontal floor slab 2 and the side wall panel 1 can be improved.
[0042] Reference Figure 1 A foamed material layer 4 is provided at the edge between the side wall panel 1 and the horizontal floor slab 2. The foamed material layer 4 can be made of materials such as epoxy resin. The foamed material layer 4 is used to quickly solidify and cover the surface of the I-beam 11, vertical steel bars 12 and bolts, thereby reducing the contact between the metal materials in the side wall panel 1 and the horizontal floor slab 2 and the air, thereby reducing the rusting speed of the metal materials and improving the service life of the prefabricated building.
[0043] Reference Figure 2 Multiple diagonal bracing components 3 are installed on the side wall panel 1. Each diagonal bracing component 3 includes a tie rod 31, two bearing seats 32, and two mounting pieces 33. The two ends of the tie rod 31 are fixedly connected to the bearing seats 32, and each bearing seat 32 is rotatably connected to one mounting piece 33. One mounting piece 33 is bolted to the side wall panel 1, and the other mounting piece 33 is bolted to the ground. When the diagonal bracing components 3 are installed on the side wall panel 1, the tie rod 31 is tilted and supports the side wall panel 1. The diagonal bracing components 3 are used to support the side wall panel 1, reducing the probability of the side wall panel 1 tilting and collapsing during prefabricated building construction.
[0044] The implementation principle of this application embodiment is as follows: by setting an I-beam 11 in the side wall panel 1, the I-beam 11 can connect two adjacent side wall panels 1 and horizontal floor slab 2 in the vertical direction, thereby enabling the side wall panel 1 and horizontal floor slab 2 to be quickly connected. The connected side wall panel 1 and horizontal floor slab 2 have better connection stability and better structural strength.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
