Description

Technical Field

[0001] The utility model relates to a fixing and calibrating device for ALC plates, belonging to the technical field of secondary structure construction of buildings. Background Art

[0002] The ALC plate is made of autoclaved aerated lightweight concrete and belongs to high-quality new building materials. It is easy to install and has good economy. When installing the ALC plate, due to its large volume and heavy self-weight, multiple people are required to cooperate for installation. Usually, the fixing method of the top of the ALC plate to the concrete slab surface is to use a shot-fired galvanized steel pipe clamp to fix it on the concrete slab surface, and the pipe clamp extends into the reserved hole of the ALC plate for fixing. However, due to the heavy self-weight of the ALC plate and the fact that the pipe clamp is fixed on the slab surface and cannot be moved, the installation difficulty is large. If the installation and positioning of the pipe clamp are inaccurate and it cannot be moved, it is easy to cause the ALC plate to be installed out of position. Content of the Utility Model

[0003] Based on the above, the utility model provides a fixing and calibrating device for ALC plates to improve the fixing efficiency and positioning accuracy of the ALC plate to the concrete surface.

[0004] The technical solution of the utility model is: a fixing and calibrating device for ALC plates, comprising:

[0005] A plate body unit, which includes a concrete floor slab and a precast ALC partition wall panel. The precast ALC partition wall panel is installed at the bottom of the concrete floor slab, and a positioning hole is opened at the top of the precast ALC partition wall panel;

[0006] A calibration unit, including an embedded plate, a movable clamp, a clamp fixing plate, a calibration nut and an installation bolt. The embedded plate is anchored at the bottom of the concrete floor slab. Both ends of the movable clamp are installed at the bottom of the embedded plate through supports. The clamp fixing plate is slidably installed on the movable clamp. The calibration nut is fixed at the bottom of the clamp fixing plate. The lower end of the installation bolt extends into the positioning hole and the upper end is connected to the calibration nut.

[0007] In one example, the embedded plate is provided with embedded steel bars, and the embedded steel bars are connected to the steel bars of the concrete floor slab and poured simultaneously.

[0008] In one example, the movable clamp is composed of two spaced guide bars. The clamp fixing plate is placed on the two guide bars. The calibration nut passes through the gap between the two guide bars and is connected to the clamp fixing plate.

[0009] Advantages of the present utility model: By using the embedded plate, movable clamp, clamp fixing plate, calibration nut and installation bolt as the connection device between the ALC board and the concrete floor surface, compared with the traditional pipe clamp fixing and installation method, it has the advantages of fast installation rate, adjustable installation position, guaranteed installation quality and accurate installation position.

[0016] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0017] Please refer to Figures 1 to 3 , in this embodiment, a fixing and calibration device for ALC plates includes a plate body unit and a calibration unit. The plate body unit includes a concrete floor slab 11 and a precast ALC partition wall board 12. The precast ALC partition wall board 12 is installed at the bottom of the concrete floor slab 11, and a positioning hole 13 is provided at the top of the precast ALC partition wall board 12. The calibration unit includes an embedded plate 21, a movable clamp 22, a clamp fixing plate 23, a calibration nut 24 and an installation bolt 25. The embedded plate 21 is anchored at the bottom of the concrete floor slab 11. Both ends of the movable clamp 22 are installed at the bottom of the embedded plate 21 through a support 26. The clamp fixing plate 23 is slidably installed on the movable clamp 22 and can move along the length direction of the movable clamp 22. The calibration nut 24 is fixedly connected to the bottom of the clamp fixing plate 23. The lower end of the installation bolt 25 extends into the positioning hole 13, and the upper end is connected to the calibration nut 24.

[0018] A plurality of embedded steel bars 27 are provided on the embedded plate 21. The embedded steel bars 27 are connected to the steel bars of the concrete floor slab 11 and poured simultaneously. After pouring, the embedded plate 21 is located on the bottom surface of the concrete floor slab 11, thereby ensuring the reliability of the structure. It should be noted that the fixed position of the embedded plate 21 needs to be at the position where the ALC board is installed and the line is laid out.

[0019] The movable clamp 22 is composed of two guide bars arranged at intervals. The clamp fixing plate 23 is placed on the two guide bars. The size of the clamp fixing plate 23 is larger than the gap between the two guide bars. The calibration nut 24 passes through the gap between the two guide bars and is connected to the clamp fixing plate 23. The pouring nut can be aligned and connected with the installation bolt 25.

[0020] Construction method: During installation, first carry out positioning and line laying. Then, install the movable clamp 22, the clamp fixing plate 23, and the calibration nut 24 on the embedded plate 21 through the support 26. Erect the ALC board. According to the positioning, erect the ALC board at the designated position. Then adjust the clamp fixing plate 23. By rotating the clamp fixing plate 23 left and right and moving the calibration nut 24, move the calibration nut 24 to the positioning hole 13 at the top of the ALC board. Then insert the installation bolt 25 into the board positioning hole 13 and screw it into the calibration nut 24. After fixing, use special mortar to fill the gap between the concrete board surface and the ALC. Compared with the prior art, the utility model sets a fixed calibration device at the installation position of the concrete floor slab 11 and the precast ALC partition wall board 12 as the connection device between the ALC board and the concrete board surface, with a fast installation rate, adjustable installation position, guaranteed installation quality, and improved installation efficiency.

[0021] The above embodiments only represent several implementation manners of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
