TECHNICAL FIELD
[0001] The utility model belongs to the technical field of building engineering construction, and particularly relates to a track type roof separating joint construction device. BACKGROUND
[0002] In building engineering, the construction quality of the roof separating joint has an important influence on the overall performance of the building. The traditional separating joint construction methods mainly include embedding a finished product separating joint, embedding a foam plate material for later removal to form a separating joint, and cutting a separating joint in the later period. However, these methods have certain defects. Embedding a finished product separating joint affects the shrinkage effect and is not easy to control the finished product elevation; embedding a foam plate is prone to damage during the construction process, and has problems such as difficulty in removal, non-straightness of the separating joint, and difficulty in controlling the elevation, which affect the forming effect; and cutting a separating joint in the later period is time-consuming and laborious, and the cutting depth and straightness of the cut joint are difficult to control. SUMMARY
[0003] The utility model solves the technical problems of overcoming the defects of the prior art, and provides a track type roof separating joint construction device to solve the problems of the prior art, i.e., embedding a finished product separating joint affects the shrinkage effect and is not easy to control the finished product elevation; embedding a foam plate is prone to damage during the construction process, and has problems such as difficulty in removal, non-straightness of the separating joint, and difficulty in controlling the elevation, which affect the forming effect; and cutting a separating joint in the later period is time-consuming and laborious, and the cutting depth and straightness of the cut joint are difficult to control.
[0004] To achieve the above object, the utility model provides the following technical scheme: a track type roof separating joint construction device, comprising:
[0005] A track type embedded part is embedded in the roof leveling layer.
[0006] A separating joint cover plate is installed on the track type embedded part.
[0007] A joint pulling device slides on the track type embedded part.
[0008] Preferably, the track type embedded part comprises a glass embedded part and a cement mortar layer, and the glass embedded part is embedded in the roof leveling layer through the cement mortar layer.
[0009] Preferably, the separating joint cover plate is a pie-shaped joint cover plate, and the top surface elevation of the pie-shaped joint cover plate is consistent with the finished surface elevation of the pouring body.
[0010] Preferably, the joint pulling device comprises a joint pulling handle and a joint pulling head, and the joint pulling handle can be installed with handles of different lengths.
[0011] Preferably, the top elevation of the track type embedded part is 5-15 mm apart from the joint top elevation.
[0012] Compared with the prior art, this utility model provides a track-type roof expansion joint construction device, which has the following advantages:
[0013] This invention achieves stable fixing of glass pre-embedded parts through the use of track-type pre-embedded parts, providing a solid foundation for subsequent construction. It avoids problems such as easy damage to foam boards and the impact of finished expansion joints on shrinkage effect in traditional pre-embedded methods. The patch-type expansion joint cover plate can not only accurately control the elevation, ensuring the flatness and consistency of construction, but also replace the traditional patching process, simplifying the construction process. The joint puller makes the troweling of the expansion joints straighter and the external corners more square. At the same time, its adjustable handle adapts to the needs of different construction scenarios. Pre-embedded parts do not need to be removed, reducing construction steps, lowering construction costs, and improving the overall efficiency of construction. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figs. 1-3This utility model provides a technical solution: a track-type roof expansion joint construction device, comprising: a track-type embedded part 1, which is embedded in the roof leveling layer; an expansion joint cover plate 2, which is installed on the track-type embedded part 1; and a joint puller 3, which slides on the track-type embedded part 1, making the construction process more stable and precise. The embedded part 1 provides solid support for subsequent processes, ensuring the accurate position and stability of the expansion joint.
[0024] In this utility model, preferably, the track-type embedded part 1 includes a glass embedded part 11 and a cement mortar layer 12. The glass embedded part 11 is embedded in the roof leveling layer through the cement mortar layer 12, which not only improves the stability of the glass embedded part 11, but also avoids problems such as easy damage to the foam board and the impact of the finished expansion joint on the shrinkage effect in traditional embedding methods. The expansion joint cover 2 is a patch-type expansion joint cover, the elevation of which is consistent with the elevation of the finished surface of the poured body. This not only allows for precise control of the elevation, ensuring the flatness and consistency of the construction, but also replaces the traditional patching process, simplifies the construction process, and improves construction efficiency. By reducing construction errors and ensuring the quality and aesthetics of large-area construction, the joint-pulling device 3 includes a joint-pulling handle 31 and a joint-pulling head 32. The joint-pulling handle 31 can be fitted with handles of different lengths. The top elevation of the track-type embedded part 1 is reserved at a distance of 5-15mm from the top elevation of the joint, which allows the joint-pulling device 3 to adapt to the needs of different construction scenarios, improving the convenience and flexibility of construction. The joint-pulling device 3 slides on the track-type embedded part 1 to perform secondary troweling on the joint, ensuring the straightness of the joint and the squareness of the external corners, significantly improving the construction quality, while also increasing construction efficiency and reducing errors caused by manual operation.
[0025] The working principle and usage process of this utility model are as follows: First, according to the pre-planned location and elevation, the glass pre-embedded part 11 is pre-embedded using 1:3 cement mortar. A gap 3-5mm larger than the glass thickness is left at the intersection of longitudinal and transverse joints. The remaining parts are continuously set. After the mortar of the glass pre-embedded part 11 has fully set, the expansion joint cover plate 2 is installed on it. Note that the expansion joint cover plate 2 should be continuously set. After installation, concrete / mortar can be poured. A 5-15mm gap is reserved between the top elevation of the glass pre-embedded part 11 and the top elevation of the joint. The top surface elevation of the expansion joint cover plate 2 is consistent with the finished surface elevation of the poured body. After the initial setting and before the final setting of the poured concrete / mortar, the expansion joint cover plate 2 is removed. A joint puller 3 that can slide on the glass pre-embedded part 11 is used to perform a second pressing of the expansion joint to ensure the straightness of the expansion joint and the squareness of the external corners. Finally, sealant is applied to fill the joints to complete the construction.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
