Description

Technical Field

[0001] The invention belongs to the field of construction engineering, and in particular relates to an assembled integral large panel. Background Art

[0002] Prefabricated buildings meet the requirements of building industrialization and green environmental protection, especially my country's industrial policies on green buildings and building industrialization, which have led to an increasing demand for prefabricated buildings. Prefabricated panels are one of the main contents of prefabricated buildings.

[0003] Existing prefabricated exterior wall panels are strips, large panels assembled from prefabricated strips horizontally assembled, and prefabricated concrete integral panels. Prefabricated exterior wall strips are small in size, cumbersome to install, poor in integrity, and not suitable for installation with exterior wall finishes. Although prefabricated exterior wall strips have the advantages of easy manufacturing and low cost, the assembled exterior walls have the disadvantage of cracking and leakage at the assembly seams, and have not been promoted for use in residential and public buildings; and large panels assembled from prefabricated strips horizontally assembled cannot meet the requirements of wind and earthquake resistance, and cannot be promoted for use in high-rise buildings.

[0004] Concrete precast integral panels have two structures: with insulation sandwich layer and without sandwich layer. They are mainly used in residential buildings. Both types require customized formwork and customized steel mesh, with many specifications, low production efficiency and high cost.

[0005] In order to solve and improve the above problems, an invention patent named "A Prefabricated Integral Exterior Wall Panel" (Chinese patent application publication number is CN107217783A, application publication date: 2017.09.29, hereinafter referred to as Document 1) proposed a technical solution. The patented technical solution uses multiple vertical prefabricated panels to splice, and at the same time sets upper and lower frames, pins or full-length dowels; when there is an opening, horizontally placed prefabricated panels are set above and below the opening, and reinforcing steel is set around the opening. This technology better meets the use of prefabricated strips on high-rise buildings, and compared with traditional prefabricated strips or horizontally assembled large panels, it can meet the requirements of wind resistance and earthquake resistance, and the cost is relatively low. It has been applied in the projects hosted by my company.

[0006] The disclosed invention patent "A multifunctional combined lightweight concrete curtain wall and its manufacturing method" (Chinese patent application publication number CN103374986A, application publication date: 2013.06.28, hereinafter referred to as Document 2) introduces the second technical solution. The patented technical solution adopts a plurality of vertical lightweight concrete slab units to be spliced ​​horizontally, and the upper and lower ends of the slab units are connected together by snapping and fixing them to the frame of the grooved steel section; as an optimized solution, holes are drilled in the splicing direction of the slabs, steel bars are inserted and adhesive is poured into the holes to anchor the steel bars in the through holes to strengthen the splicing strength of the slabs. The patent also discloses a technical solution for setting window holes in the slabs using the above-mentioned splicing technology, and the technical solution is provided with a mounting frame connected to the window at the inner edge of the window hole.

[0007] Another disclosed invention patent, "A pre-assembled lightweight wall panel that can be industrially produced" (Chinese patent application publication number CN202380609A, application publication date: 2011.12.23, hereinafter referred to as Document 3), introduces a third technical solution. This patented technical solution uses multiple lightweight wall panels to be bonded and spliced ​​together along the width of the panel, and opens a number of through-reinforcement holes that penetrate the width of the panel and are located in the center of the thickness of the panel. Tensioned tension steel bars are arranged in the through-reinforcement holes (tensioned by nuts with pads at the ends), and each strip of board is assembled into a wall panel after pressurized grouting in the through-reinforcement holes. This technical solution requires the diameter of the through-reinforcement holes to be 35 to 40 mm.

[0008] However, there are some problems in the application of document 1 technology, the main problems are:

[0009] 1. The reserved holes for the transverse prefabricated panels with dowels in the opening have low efficiency, high cost and low structural rigidity. There are two types of reserved holes for full-length dowels in terms of technology: reserved holes during the production of slats and holes drilled. Since the production process of slats is fixed, a dedicated production line is required to reserve holes during the production of slats, which has high cost and low production capacity. Therefore, a more optimized solution is to purchase general slats for drilling. The document 1 technology has relatively long upper and lower horizontal panels at the opening. When the length is greater than 1m, the reserved holes for the full-length dowels cannot be made by drilling. Only pre-buried pipes can be used during the production of slats, which has low efficiency and high cost. Therefore, in actual use, no full-length dowels are set in the upper and lower transverse prefabricated slats at the opening, but this results in a decrease in the overall structural rigidity (such as Figure 1 shown).

[0010] 2. The module of the horizontal plate under the opening does not match, resulting in material waste. The standard height requirement under the building opening window is 950mm (900mm from the building surface to the window sill, 50mm from the structural surface to the building surface), while the national standard specification of prefabricated strips is 600mm wide. With 600+350mm splicing, the remaining 250mm of the remaining material is difficult to use, resulting in a lot of material waste (such as Figure 2 shown).

[0011] 3. The cost of the upper and lower frames is high. The material cost of the upper and lower frame steel accounts for about 20-30% of the total cost of the prefabricated component (the cost of the component with openings will be higher). The application of this frame in the document 1 technology is to meet the splicing strength and rigidity to meet the requirements of transportation, installation and engineering design, and also serves as a structural construction connected to the main structure (point supports and upper and lower frame connections are set in the main structure).

[0012] 4. There are cracks in the board seams, and waterproofing is required (such as Figure 3 shown);

[0013] The solution proposed in Document 2 has certain application value, but there are other problems. The main problems are:

[0014] 1. The joints of the panels are not bonded and are prone to cracking.

[0015] 2. It is necessary to set upper and lower borders, which is costly, troublesome to make, and inefficient as described in Document 1.

[0016] 3. Setting window rib holes for injecting adhesive can improve the problem of cracking in the board joints, but the grouting process is complicated, it is not easy to ensure full injection, the joints of the spliced ​​boards are not sealed, and it is easy to leak grout, and the cost is high and the production efficiency is low.

[0017] 4. When a window hole is set in the middle of the board, only an installation frame connected to the window is set around the hole. The window hole weakens the strength of the composite wall panel, and the composite wall panel cannot meet the strength requirements and is unsafe.

[0018] 5. No solution is provided for the gap in the combined board.

[0019] The solution proposed in document 3 does not set the upper and lower connecting frames, and the board seams are bonded (but no bonding solution is provided). Compared with document 2, it can better solve some problems in application, such as better crack resistance. However, there are still some important problems to be solved, the main problems are:

[0020] 1. It is very difficult to perform pressure grouting after reinforcing the reinforcement in the reinforcement hole. The work is cumbersome, the production efficiency is low, the cost is high, and it is difficult to promote and apply. Especially for materials with high water absorption and high water permeability such as ALC strip boards, it is difficult to perform pressure grouting. In order to improve the difficulty of grouting and the quality of grouting, document 3 adopts the method of setting multiple pressure grouting holes on the board for multiple grouting, which further reduces the production efficiency.

[0021] 2. No technical solution for opening holes or gaps is provided. Summary of the invention

[0022] The technical problem to be solved by the present invention is to provide an assembled integral large plate in which prefabricated plates are arranged vertically.

[0023] The main technical approach of the present invention is to use the tie rod technology to splice the prefabricated large panels to ensure the rigidity and strength of the assembled integral large panels. The present invention adopts a variety of tie rod technology solutions. Unlike Documents 1 and 2, these solutions do not require the setting of upper and lower frames, simplify the structure, improve production efficiency, and reduce the cost. The details are as follows:

[0024] 1. Solution 1: The tie bars are arranged along the width on the outer surface of the assembly board. The tie bars are usually in the form of flat strips (such as carbon fiber or glass fiber), which are convenient for splicing the assembly boards together on the outer surface of the assembly board by gluing. The production is convenient, efficient and low-cost.

[0025] 2. Scheme 2: Add mechanical anchors (such as nuts and pads) at both ends of the reinforcement. Unlike document 3, by setting up a reasonable mechanical anchor device, there is no need for pressure grouting in the reinforcement hole. Not only is the implementation plan feasible, but it also greatly improves production efficiency and reduces construction costs. When pre-stressing is applied to the full-length reinforcement, the stiffness and crack resistance of the large plate will be better.

[0026] This patent shows through theoretical calculation and test data that for ALC pre-assembled panels with larger panel sizes (width 4.2m, height 3.0m), 3 M10 tie bars are set, and 70x70 steel pads are used at both ends of the tie bars. The requirement that the panel joints will not crack under the action of 1.5 times the dead weight is met. It meets the requirements of prefabricated buildings for the production, transportation, installation and use of building exterior wall panels. The specific experimental data are as follows:

[0027]

[0028] (The above test uses a vertically placed plate, with supports and pads at both ends of the plate, and loads are applied at 1 / 4 of the span at both ends of the plate. In Scheme A, the plate joints are fully bonded with special masonry mortar, no prestress is added, and Scheme A is not loaded to the failure load; Scheme B applies a pre-tension of about 7.0kN, the plate joints are dry-jointed (no special masonry mortar is used for bonding), and repair mortar is applied to the joints of the plate surface to observe the development of the cracks.)

[0029] 3. Scheme 3: Cement mortar and other cementitious materials are poured into the holes through which the reinforcement is passed to ensure that the reinforcement does not slip or pull out. This scheme differs from document 2 in that it does not require connecting frames of grooved steel sections at the upper and lower ends of the plate, and it differs from document 3 in that it does not require reinforcement tensioning devices at both ends of the reinforcement, thereby simplifying the production process.

[0030] The above three technical solutions adopted by this patent can all achieve the rigidity and strength required for assembling integral large panels. And these technical solutions can ensure that the panel seams are tighter and the working performance is good. In the case where the large panel has a hole or a gap, the large panel is strengthened by setting a reinforcing frame at the edge of the hole or the gap, which guarantees the overall strength of the large panel to a limited extent. The technical principle is:

[0031] When the prefabricated panels are spliced ​​in the vertical force or in the plane along the plate seam direction deformation position (transportation, hoisting installation and use position), along the vertical shear deformation or vertical bending (such as Figure 4 , Figure 5 As shown in the figure, the full-length tie bars will be stretched, making the plate joints more tightly packed without cracking (if prestress has been applied in advance) or further cracking. At the same time, the squeezing force will form friction in the plate joints to ensure that the plate joints will not move or deform. The full-length tie bars also provide the lower tensile bearing capacity of the assembled integral large plate under bending, and together with the friction in the plate joints, provide the plate joints with shear bearing capacity.

[0032] When the spliced ​​large plate is in a tensile deformation position (use position) perpendicular to the plate seam, such as temperature deformation during use, the direct effect of the tie bars (especially when prestress has been applied in advance) can limit the cracking of the plate seam or put the plate seam in a tensile state (when prestress has been applied in advance).

[0033] The present invention is achieved through the following technical solutions:

[0034] An assembled integral large panel includes a plurality of vertical prefabricated panels arranged vertically, wherein the vertical prefabricated panels are connected together by through-length tie bars arranged on the outer surfaces of the prefabricated panels, and the through-length tie bars and the prefabricated panels are bonded together by an adhesive.

[0051] Compared with the existing technology, the specific advantages are as follows:

[0052] 1. The use of tie rod technology can ensure the structural strength and rigidity of the assembled large panels without setting upper and lower frames, greatly saving steel, simplifying the assembly process, improving efficiency, and greatly reducing the cost.

[0053] 2. Compared with the technical solution in Document 3, there is no need to perform pressure grouting in the reinforcement holes, which greatly simplifies the manufacturing process, improves production efficiency and reduces costs.

[0054] 3. As mentioned above, the technical solution of Document 1 has a hole width greater than 1m (most of the building window openings are greater than 1m), because it is difficult to make the reserved holes for the dowels, which reduces the efficiency and the integrity of the large board. The lower or upper plate of the hole is vertically spliced, and the width of each spliced ​​prefabricated plate is no more than 1m, which is convenient to drill and efficient, and there is no such problem.

[0055] 4. As mentioned above, the technical solution of Document 1 does not match the module of the horizontal plate under the opening, resulting in material waste. The opening lower plate is vertically spliced, and the vertical plate is mass-produced according to the height of the window opening lower plate of 950mm, which meets the standard specifications of scale, without material waste and greatly saves material costs.

[0056] 5. Bonding technology for spliced ​​plate seams. When prefabricated plates are spliced, glue or mortar is applied to the seams along the thickness direction. After the seam glue or mortar hardens and bonds, the anti-leakage ability of the spliced ​​plate seams is equal to that of the non-spliced ​​parts. At the same time, it works together with the full-length tie bars to greatly improve the rigidity and strength of the assembled integral large panels.

[0057] The present invention uses strips to assemble vertically. For buildings such as residential buildings with consistent floor heights, the strips have fewer specifications, high production efficiency, and low cost. The assembled integral outer panels assembled using the present invention can achieve a smooth surface and can be free of plastering, thereby saving materials, increasing construction efficiency, and reducing costs. The present invention further improves construction efficiency and quality and saves costs by pre-preparing the exterior wall decoration in the factory and then hoisting them together. If the present invention uses materials such as aerated concrete to produce strips, they can be made into self-insulating panels after assembly, which can save materials, improve construction efficiency, and further reduce costs.
