Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall panels, in particular to an assembled low-energy consumption concrete building exterior wall panel. Background Art

[0002] Low-energy concrete building exterior wall panels, also known as energy-saving concrete exterior wall panels, are a type of building material with good thermal insulation performance and low energy consumption. Low-energy concrete exterior wall panels use special materials and structural designs to give them high thermal insulation performance. They usually use heat storage materials such as polystyrene particles, rock wool, etc., which have good thermal insulation and thermal insulation effects. In addition, the surface of the exterior wall panels can be waterproofed to improve their moisture-proof performance. Compared with traditional exterior wall materials, low-energy concrete exterior wall panels can reduce energy consumption and emissions during construction.

[0003] Existing assembled low-energy concrete building exterior wall panels are mostly fixedly connected with the exterior wall panels by a clamping structure. For example, my invention patent CN201510207112.9, application date April 28, 2015, discloses a hanging part for fixing an insulation board on a foundation wall, including two flat bases and a raised hanging joint in the middle. The hanging joint is provided with a protruding large head for connecting an insulation board matching its shape. The defects in the prior art are: 1) Since the assembled low-energy exterior wall panels are of small mass, they are greatly disturbed by natural wind when on the windward side. The clamping structure has limited firmness and is prone to loosening, thereby allowing wind to enter the joints and reducing the thermal insulation performance of the building; 2) The clamping connection is not convenient for disassembly and replacement of individual exterior wall panels during later maintenance, which makes it inconvenient to operate when installing and disassembling the exterior wall panels. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and the utility model provides an assembled low-energy consumption concrete building exterior wall panel.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] An assembled low-energy concrete building exterior wall panel comprises an embedded channel steel and an assembled low-energy concrete exterior wall panel, wherein the embedded channel steel is embedded in the wall of the building exterior wall, a positioning plate is installed on the rear side wall of the assembled low-energy concrete exterior wall panel, and a positioning pin is arranged on the end face of the positioning plate, a driving mechanism is arranged inside the rear side wall of the assembled low-energy concrete exterior wall panel and two groups of positioning plates, and a locking block for assembling and locking the embedded channel steel and the assembled low-energy concrete exterior wall panel is fixedly installed on the rear end of the rotating part of the driving mechanism.

[0007] Furthermore, the embedded channel steel comprises a channel steel body, a mounting groove is provided on the surface of the channel steel body, a positioning through hole is provided on the surface of the channel steel body, and the positioning through holes are located on the left and right sides of the mounting groove.

[0008] Furthermore, the assembled low-energy concrete exterior wall panel includes a low-energy concrete exterior wall panel body, a first assembly groove is opened on the right side wall of the low-energy concrete exterior wall panel body, and a second assembly groove is opened on the left side wall of the low-energy concrete exterior wall panel body. When two groups of the low-energy concrete exterior wall panel bodies are assembled, the first assembly groove is meshed with the second assembly groove.

[0009] Furthermore, the driving mechanism includes a rotating shaft, and the two groups of positioning plates are internally rotatably plugged with a rotating shaft, a hexagonal protruding rod is fixedly installed on the right end of the rotating shaft, a worm is fixedly sleeved on the surface of the rotating shaft, a connecting shaft is rotatably installed on the rear side wall of the low-energy concrete exterior wall panel body, a worm gear is fixedly sleeved on the surface of the connecting shaft, a guide groove is opened on the surface of the worm gear, and a limit pin is fixedly installed on the rear side wall of the assembled low-energy concrete exterior wall panel, the arc angle of the guide groove is ninety degrees, and the limit pin and the guide groove are plug-in installed.

[0010] Furthermore, the width of the locking block and the diameter of the connecting shaft are equal to the width of the mounting groove, and the length of the locking block is greater than the width of the mounting groove.

[0011] Furthermore, when the assembled low-energy concrete exterior wall panel is installed, the end surface of the positioning plate is fitted with the front end of the embedded channel steel, and the positioning pin is plug-connected with the positioning through hole.

[0012] The beneficial effects of the utility model are as follows:

[0013] The driving mechanism is rotated by the handle so that the driving mechanism adjusts the locking block to a horizontal state, and the locking block and the positioning pin are plugged into the surface of the embedded channel steel. The assembled low-energy concrete exterior wall panel is positioned by plugging the positioning pin into the surface of the embedded channel steel. The locking block is driven by the driving mechanism to rotate ninety degrees, so that the locking block is adjusted from a horizontal position to a vertical position, thereby locking the assembled low-energy concrete exterior wall panel, so that the embedded channel steel and the assembled low-energy concrete exterior wall panel are fixedly connected. This anchoring and locking structure is more secure than the simple clamping in the prior art and is not easy to loosen the structure. When disassembling this solution, the driving mechanism is rotated by a wrench, so that the locking block is driven to rotate ninety degrees, so that the locking block is adjusted from a vertical position to a horizontal position, so that the embedded channel steel and the assembled low-energy concrete exterior wall panel are unlocked, so that the assembled low-energy concrete exterior wall panel can be disassembled, thereby facilitating the removal of a single exterior wall panel.
