Specific Embodiments

[0013] The following further elaborates the utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0014] The embodiment of the utility model relates to a control device for the plastering thickness of an external wall composite insulation board, as Figures 1-3As shown in the figure, it includes an outer member 1 and an inner member 2. The outer member 1 consists of three parts, namely a threaded steel bar head 5 combined with a cast-in-place concrete member 3, an anchoring middle part 6 anchored into a thermal insulation board 4, and a first limiting piece 7 at the tail. In the middle of the end face of the first limiting piece 7, there is an insertion and extraction hole 12, which extends into the anchoring middle part 6; the inner member 2 is a post-embedded part. The front end of the inner member 2 is an insertion and extraction adjusting rod 10 inserted into the insertion and extraction hole 12. The rear end of the inner member 2 is a second limiting piece 11, which can be grasped. Axially arranged on the insertion and extraction adjusting rod 10 are a plurality of insertion and extraction parts 13, which are frustum-shaped. One end of the insertion and extraction part 13 close to the second limiting piece 11 is small and the other end is large. The shape of the insertion and extraction hole 12 matches the shape of the insertion and extraction part 13. Such a shape design of the insertion and extraction part 13 makes it relatively easy to pull out the insertion and extraction adjusting rod 10 outward and relatively difficult to insert it inward, but it can be inserted as long as enough force is applied.

[0015] As Figure 1 and 2 shown in the figure, the outer member 1 consists of a threaded steel bar head 5, an anchoring middle part 6 with barbs 8, and a first limiting piece 7. After the thermal insulation board 4 is installed and fixed, the anchoring middle part 6 is anchored into the thermal insulation board. Among them, the threaded steel bar head 5 is buried in the cast-in-place concrete member 3 and is fully combined with the cast-in-place concrete member 3; barbs 8 are evenly arranged on the outer surface of the anchoring middle part 6. The setting of the barbs 8 makes the outer member 1 firmly fixed to the thermal insulation board 4 and prevents it from falling off. When the outer member 1 is anchored into the specified position, the first limiting piece 7 is closely attached to the outer side of the thermal insulation board 4.

[0016] As Figure 3 shown in the figure, the inner member 2 is a fixed whole. The width of the second limiting piece 11 is slightly smaller than the width of the first limiting piece 7, and the length of the insertion and extraction adjusting rod 10 is set according to the adjustment needs.

[0017] Before the device is installed, the inner member 2 should be buried in the outer member 1, and the second limiting piece 11 is closely attached to the first limiting piece 7. By pulling out the adjusting rod 10 outward, the position of the second limiting piece 11 can be adjusted to obtain the plastering thickness required for the plastering thickness.

[0018] For the control device of the plastering thickness of the external wall composite thermal insulation board, the main movement process is as follows: During the formwork installation and construction stage, the whole device is set according to the quantity requirement of the thermal insulation board 4; after the cast-in-place concrete member 3 is poured, the threaded steel bar head 5 of the outer member 1 is buried in the cast-in-place concrete member 3, and the first limiting piece 7 at the tail is closely attached to the outer side of the thermal insulation board 4. Before the external wall is plastered, by pulling out the adjusting rod 10 outward, the second limiting piece 11 can be adjusted to the required position. Through the cooperation of the insertion and extraction hole 12 and the insertion and extraction part 13, the inner member 2 is kept stationary to achieve the purpose of stability.

[0019] On the end face of the first limiting piece 7, a plurality of reinforcing ribs 9 are arranged around the anchoring middle part 6. The reinforcing ribs 9 are provided to strengthen the structural strength and stability of the first limiting piece 7 and the anchoring middle part 6.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0021] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here will be made.

[0022] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meaning. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0023] The above has introduced in detail a control device for the plastering thickness of an external wall composite insulation board provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
