Description

Assembled integral type large plate
Technical Field
The utility model belongs to the building engineering field especially relates to an assemble integral big board.
Background
The prefabricated building meets the requirements of building industrialization and environmental protection, particularly the industrial policy of green building and building industrialization in China, and the demand for the prefabricated building is more and more large. Prefabricated panels are one of the main contents of prefabricated buildings.
The existing prefabricated external wall panel adopts battens, assembled large panels and concrete prefabricated integral panels which are horizontally assembled by the prefabricated battens, the prefabricated external wall battens are small in size, complex in installation and poor in integrity, and the prefabricated external wall panel is not suitable for installation of external wall veneers. Although the prefabricated external wall batten has the advantages of convenient manufacture and low cost, the assembled external wall has the defects of cracking and leakage on the assembly joint and cannot be popularized and used in houses and public buildings all the time; and the assembled large plate horizontally assembled by the prefabricated battens cannot meet the requirements of wind resistance and earthquake resistance and cannot be popularized and used in high-rise buildings.
The prefabricated integral concrete slab has two kinds of structures with the sandwich layer of taking the heat preservation and does not take the sandwich layer, mainly is applied to the house, and no matter which kind all needs customization template and customization reinforcing bar rack, the specification is many, and the preparation is efficient, and is with high costs.
In order to solve the above problems, an invention patent (chinese patent application publication No. CN107217783A, application publication date: 2017.09.29, hereinafter referred to as document 1) entitled "an assembled integral external wall panel" proposes a technical solution. According to the technical scheme, a plurality of vertical prefabricated plates are spliced, and an upper frame, a lower frame, pins or full-length dowel bars are arranged at the same time; when an opening is formed, prefabricated plates which are transversely placed are arranged up and down on the opening, and meanwhile, reinforced section steel is arranged on the periphery of the opening. The technology better meets the use of the prefabricated lath on high-rise buildings, can meet the requirements of wind resistance and earthquake resistance compared with the traditional prefabricated lath or a horizontally assembled large plate, has lower cost, and has been applied to the engineering hosted by the company of the inventor.
The second technical proposal is introduced in the published invention patent of multifunctional combined lightweight concrete curtain wall and the manufacturing method thereof (Chinese patent application publication No. CN103374986A, application publication No. 2013.06.28, hereinafter referred to as document 2). According to the technical scheme, a plurality of vertical lightweight concrete plate units are transversely spliced, and the upper ends and the lower ends of the plate units are connected together through frames of section steel with grooves in a clamping and fixing manner; as an optimized scheme, a through hole is drilled in the plate splicing direction, a steel bar is penetrated into the through hole, and an adhesive is poured into the through hole to anchor the steel bar in the through hole so as to reinforce the splicing strength of the plate. This patent has simultaneously announced the technical scheme who sets up the window opening in the board in adopting above-mentioned concatenation technique, and this technical scheme is equipped with the installing frame of being connected with the window at the window opening inner edge.
Another disclosed utility model 'a pre-assembled light wall panel for industrial production' (Chinese patent application publication No. CN202380609A, application publication No. 2011.12.23, hereinafter referred to as document 3) introduces a third technical solution. This patent technical scheme adopts the mutual concatenation that bonds of polylith light weight wallboard along board width direction to set up the bar hole that passes through that a plurality of runs through the board width and is located thick center of board, set up the counter-tension bar of tensioning (setting up the nut tensioning of taking the backing plate through the tip) in the bar hole, and assemble into a wallboard with each slat after the downthehole pressurization slip casting of bar. The technical scheme requires that the diameter of the rib penetrating hole is 35-40 mm.
However, the document 1 technology has some problems in application, and the main problems are that:
1. the hole reserved by the dowel bars of the transverse precast slab at the hole has low work efficiency, high cost and low structural rigidity. The through-length dowel bar reserved hole is reserved and drilled during the production of the strip plate in the process, and a special production line is reserved during the production of the strip plate due to the fact that the production process of the strip plate is fixed, cost is high, productivity is low, and the scheme is optimized to purchase general strip plate drilled holes. According to the technology of the document 1, the upper transverse plate and the lower transverse plate of the opening are longer, when the length is larger than 1m, the through-long dowel bar reserved holes cannot be manufactured through drilling, only the pre-buried pipes during production of the laths can be adopted, the working efficiency is low, the cost is high, and therefore in actual use, through-long dowel bars are not arranged in the upper transverse prefabricated laths and the lower transverse prefabricated laths of the opening, but the result that the rigidity of the whole structure is reduced is brought (as shown in fig. 1).
2. The modulus of the transverse plate under the opening is not matched, which causes material waste. The height standard requirement under the building entrance to a cave window opening is 950mm (wherein the building surface course is 900mm to the windowsill, and the structure surface course is 50mm to the building surface course), and the national standard specification of the prefabricated slat is 600mm wide, adopts 600+350mm concatenation, and remaining 250mm clout is difficult to utilize, causes a large amount of materials extravagant (as shown in figure 2).
3. The upper and lower rims are costly. The material cost of the upper and lower frame section steel accounts for about 20-30% of the whole prefabricated part cost (the cost of the member with the opening is higher). The application of the frame in the document 1 technology is to meet the requirements of splicing strength and rigidity to meet the requirements of transportation, installation and engineering design, and simultaneously, the frame also has the structural function of being connected with a main body structure (a point support is arranged in the main body structure and is connected with an upper frame and a lower frame).
4. Cracks exist in the plate seams, and waterproof treatment is needed (as shown in figure 3);
the scheme proposed by the document 2 technology has a certain application value, but has other problems, and the main problems are as follows:
1. the joint plate seams are not bonded and are easy to crack.
2. The upper and lower frames need to be arranged, and as described in document 1, the cost is high, the manufacturing is also troublesome, and the efficiency is low.
3. The problem of slab joint cracking can be improved by arranging the window rib holes filled with the adhesive, but the grouting process is complex, full filling cannot be easily ensured, the spliced slab joints are not sealed, slurry leakage is easy to occur, the cost is high, and the production efficiency is low.
4. Under the condition that the window hole is formed in the middle of the plate, only the mounting frame connected with the window is arranged around the inside of the hole, the strength of the combined wallboard is weakened by the window hole, and the combined wallboard cannot meet the strength requirement and is unsafe.
5. No solution for providing a gap in the composite sheet is provided.
The proposal proposed by the document 3 technology does not provide an upper connecting frame and a lower connecting frame, and the plate seams are bonded (but a bonding proposal is not provided), so that the problems in application, such as better crack resistance, can be better solved compared with the proposal of the document 2. There are still some important problems to be solved, and the main problems are:
1. after the bar is penetrated in the bar penetrating hole, the pressurized grouting is difficult, the work is complicated, the production efficiency is low, the cost is high, and the popularization and the application are difficult. Especially, materials with high water absorption and high water permeability such as ALC lath are difficult to be pressure-grouted. Document 3 is to improve the problems of difficult grouting, high grouting quality and the like, and adopts a plurality of pressure grouting holes arranged on the plate for multiple times of grouting, so that the production efficiency is further reduced.
2. No technical solutions for making holes or notches are provided.
