[0002] The traditional non-load-bearing interior wall structure mainly includes block structure and plate structure. Block wall is built by blocks and mortar. This type of masonry wall is heavy and difficult to construct. It requires skilled workers to build it. The construction process is cumbersome, the construction period is long, and it is not easy to disassemble and assemble. Plate wall is composed of internal skeleton and external plate. This type of wall has poor quality and seismic performance, and is prone to tooth bursting.

[0003] At present, prefabricated buildings are developing rapidly in the construction field as a new construction production method. The production of prefabricated components of prefabricated buildings can achieve precision, reduce material waste, ensure component quality, and only need to be assembled at the construction site, which has high construction efficiency. Therefore, it is necessary to combine prefabricated buildings with non-load-bearing interior walls to improve the shortcomings of traditional wall structures of non-load-bearing interior walls. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide an assembled UHPC-nanoconcrete composite wallboard and a construction method.

[0005] The technical solution of the present invention is as follows: an assembled UHPC-nanoconcrete composite wall panel, characterized in that it comprises: a wall panel body and a mounting member;

[0006] The wall panel body is formed by integrally compounding two front and rear layers of UHPC panels and a nano concrete layer sandwiched between the two layers of UHPC panels, and the upper and lower ends of the wall panel body are respectively provided with the mounting parts;

[0007] The mounting member includes a clamping seat, a rubber block and a mounting plate. The clamping seat is a U-shaped seat and is clamped on one of the upper and lower ends of the wall panel body. The clamping seat is provided with the rubber block, and the mounting plate is provided on the rubber block. The mounting member is fixed as a whole on the wall panel body, and the mounting plate is used to connect the top beam or the bottom beam.

[0008] Furthermore, the nanoconcrete layer is connected to the UHPC board through UHPC mortar.

[0009] Furthermore, the mounting member is connected to the wall panel body via expansion screws, and the mounting plate is connected to the top beam or bottom beam via expansion screws.

[0010] Furthermore, a plurality of first reserved holes are provided in the middle of the mounting plate, the first reserved holes penetrate downwardly through the rubber block and the mounting seat, and a plurality of second reserved holes corresponding to the first reserved holes are provided on the nanoconcrete layer; in the front-to-back direction, the front and rear ends of the mounting plate both extend outwardly beyond the mounting seat, and a plurality of third reserved holes are provided on the portion of the mounting plate extending beyond the mounting seat.

[0011] A construction method of an assembled UHPC-nanoconcrete composite wallboard, characterized in that it comprises the following steps:

[0012] S1. Prefabricate two 75 mm thick UHPC panels in the factory according to the size, and then embed the nano concrete between the two UHPC panels 7 using UHPC mortar to form an integrated wall panel body;

[0013] S2. Use a mounting piece with a U-shaped mounting seat to clamp it on one of the upper and lower ends of the wall panel body, and then use expansion screws to fix the mounting piece as a whole on the wall panel body;

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0030] like Figure 1 and Figure 2 An assembled UHPC-nanoconcrete composite wall panel is shown, comprising: a wall panel body and mounting parts.

[0031] The wall panel body is formed by integrally compounding two front and rear layers of UHPC panels 7 and a nano concrete layer 8 sandwiched between the two layers of UHPC panels 7. Mounting parts are respectively provided at the upper and lower ends of the wall panel body.

[0032] The mounting member includes a clamping seat 4, a rubber block 3 and a mounting plate 2. The clamping seat 4 is a U-shaped seat and is clamped on one of the upper and lower ends of the wall panel body. The clamping seat 4 is provided with a rubber block 3, and the rubber block 3 is provided with a mounting plate 2. The mounting member is fixed on the wall panel body as a whole, and the mounting plate 2 is used to connect the top beam 1 or the bottom beam.

[0033] In specific applications, such as Figure 2 As shown, firstly, two 75 mm thick UHPC panels 7 are prefabricated in the factory according to the size, and then the nano concrete is embedded between the two UHPC panels 7 using UHPC mortar, which has strong bonding ability, to form an integrated wall panel body.

[0034] UHPC is a special concrete with ultra-high strength, ultra-low water absorption, super durability and corrosion resistance. The 75mm thick UHPC board 7 made of UHPC is light and thin, with a compressive strength of more than 150MPa and high tensile strength. Compared with ordinary concrete, it is light in weight, has low vertical gravity, and is good for earthquake resistance.

[0035] The nano concrete layer 8 is located between the two UHPC panels 7. Nano concrete is a new type of building material that applies nano technology to concrete materials and improves their performance by adding nano-scale particles or nano materials to concrete. Nano concrete has excellent mechanical properties, is light in weight but has strong compressive strength, tensile strength, etc., and has good durability and corrosion resistance.

[0036] like Figure 1 As shown, after the wall panel body is processed, when the wall panel body needs to be installed, a mounting piece needs to be installed at the upper and lower ends of the wall panel body respectively. The mounting piece includes a U-shaped clamping seat 4, which is clamped on one of the upper and lower ends of the wall panel body, wherein the distance between the two walls of the U-shaped opening of the clamping seat 4 should be consistent with the overall thickness of the wall panel body, so that the clamping seat 4 will be more stable after being clamped on the wall panel body.

[0037] The mounting seat 4 is provided with a rubber block 3, and the rubber block 3 is provided with a mounting plate 2. In actual processing, a plurality of first reserved holes are provided in the middle of the mounting plate 2, and the first reserved holes penetrate downwardly through the rubber block 3 and the mounting seat 4, and a plurality of second reserved holes corresponding to the first reserved holes are provided on the nanoconcrete layer 8. The sleeve of the expansion screw 5 can be implanted in the second reserved hole, and then the expansion screw 5 is used to pass through the first reserved hole and connect with the sleeve, and then the mounting piece can be fixedly installed on the wall panel body as a whole.

[0038] The mounting plate 2 used is rectangular in shape, and its length in the front-to-back direction is 50 mm longer than the U-shaped card-mounting seat 4. Specifically, in the front-to-back direction, the front and rear ends of the mounting plate 2 both extend outwardly beyond the card-mounting seat 4, and a number of third reserved holes are provided on the portion of the mounting plate 2 that extends beyond the card-mounting seat 4. Similarly, a number of fourth reserved holes need to be provided at the top beam 1 or the bottom beam, and then the mounting plate 2 can be connected to the top beam 1 or the bottom beam using the expansion screw 5. The installation is simple and convenient. In addition, a rubber plug 6 can be provided at the third reserved hole, which is used to cover the third reserved hole after the expansion screw 5 is screwed in to protect the expansion screw 5.

[0039] This solution has the following features:

[0040] 1. This scheme is a prefabricated assembled structure as a whole, and adopts a "building blocks" installation method, so the construction speed of the partition wall is fast and the installation is simple and quick;

[0041] 2. The main body of the wall panel is formed by the front and rear two layers of UHPC panels 7 and the nano concrete layer 8 sandwiched between the two layers of UHPC panels 7. The UHPC panels 7 have extremely high compressive strength and tensile strength, which enables the UHPC partition wall to withstand greater loads, while reducing the amount of materials used and improving the overall safety of the structure. The durability of UHPC is good, which greatly extends the life of the UHPC partition wall and saves the later maintenance costs;

[0042] 3. Good heat insulation and sound insulation performance. The interior of the wall panel is a nano concrete layer 8, which has good heat insulation and sound insulation performance of the wall. At the same time, the prefabricated UHPC board 7 and the nano concrete layer 8 are connected only by UHPC mortar. This structure can reduce the sound bridge and improve the sound blocking rate;

[0043] 4. This solution is a new type of UHPC prefabricated partition wall, which is standardized, lightweight, high-efficiency and high-performance. On the premise of ensuring that the structure meets the design requirements, it helps to reduce the difficulty of construction, shorten the construction period, and increase the life of components, paving the way for future new building industry applications.

[0044] Although a portion of the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations to these embodiments are within the scope of protection of the claims of the present invention without departing from the principles and purpose of the present invention.
