AI Technical Summary
In the prior art, the expansion joint retaining facilities during roof/scattered concrete construction have problems such as low construction efficiency, different joint widths, and prone to missing edges and corners on both sides of the joint.
The insert-type circulating expansion joint partition strip is adopted, including grid strips, grid strip cover plates, vertical plates, support cross bars and support inclined rods. It is made of stainless steel to ensure the consistent width of the expansion joints and can be removed after concrete is poured to prevent the groove body from deforming and slurry entering.
The expansion joint width is consistent, the gaps in the two sides of the joint are avoided, construction efficiency and quality are improved, and the green construction characteristics are provided.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, and specifically to a socket type turnover expansion joint separating strip. Background Technique
[0002] In the current field of building engineering, although the construction units have improved their awareness of the appearance quality in the construction of roofing and apron, and have realized the importance of process construction quality control, there are still certain technical bottlenecks in the setting of expansion joints during the construction of roofing / apron concrete. In the prior art, for the setting of expansion joints during the construction of roofing / apron concrete, construction units generally adopt traditional construction methods and traditional materials. However, these methods have the following defects: the widths of the constructed expansion joints are inconsistent, and the edges and corners on both sides of the joints are prone to chipping; there is a lack of effective tools for setting expansion joints, resulting in difficulties in improving construction efficiency and quality. Content of the Utility Model
[0003] The purpose of the utility model is to provide a socket type turnover expansion joint separating strip to solve the problems raised in the background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution:
[0005] A socket type turnover expansion joint separating strip includes a separating strip. A separating strip cover plate is installed on the upper side of the separating strip. The bottom end of the separating strip is a horizontal plate, and vertical plates are fixedly arranged perpendicularly on both sides of the horizontal plate. A support cross bar is arranged inside the separating strip, and a support diagonal bar is arranged below the support cross bar.
[0006] As a further improvement of the utility model, clamping strips are arranged on both sides inside the separating strip cover plate.
[0007] As a further improvement of the utility model, ring circles matched with the clamping strips are arranged on the upper side inside the separating strip.
[0008] As a further improvement of the utility model, the separating strip and the separating strip cover plate are made of stainless steel.
[0009] Compared with the prior art, the beneficial effect of the utility model lies in:
[0010] A socket type turnover expansion joint separating strip. The separating strip and the separating strip cover plate are made of stainless steel with a certain thickness, which increases the strength of the main body and solves the problems that the previously constructed expansion joints are either of inconsistent widths or with chipped edges and corners on both sides of the joints; horizontal support cross bars are welded at certain intervals on the upper side inside the separating strip for horizontal support to ensure the upper opening dimension and prevent the deformation of the upper opening of the groove, and at the same time provide a gripping handle for demolition. In addition, a groove cover plate is made of the same material according to the upper opening dimension of the separating strip to prevent the slurry from entering the groove during the pouring of concrete / mortar. Description of the Drawings

[0017] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0018] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0019] As Figure 1 shown, an insertion - type turnover expansion joint dividing strip includes a dividing strip 1. A cover plate 2 of the dividing strip is installed on the upper side of the dividing strip 1. The bottom end of the dividing strip 1 is a horizontal plate 12. Vertical plates 11 are fixedly arranged perpendicularly on both sides of the horizontal plate 12. A supporting cross bar 13 is arranged inside the dividing strip 1, and a supporting diagonal bar 15 is arranged below the supporting cross bar 13.
[0020] Clamping strips 21 are arranged on both sides inside the cover plate 2 of the dividing strip.
[0021] Rings 14 cooperating with the clamping strips 21 are arranged on the upper side inside the dividing strip 1.
[0022] The dividing strip 1 and the cover plate 2 of the dividing strip are made of stainless steel.
[0023] Working principle of the utility model: During use, the dividing strip 1 is installed section by section according to the pre-sprayed ink line. After the installation of the whole dividing strip 1 is completed, the upper opening is pulled with a wire for fine adjustment to ensure the straightness of the whole joint. After the plaster cake hardens, the dividing strip cover plate 2 can be covered and the construction of concrete / mortar can be carried out. The dividing strip 1 can be removed not only after the casting body reaches a certain strength, but also after curing to the design strength. First, the dividing strip cover plate 2 is removed, and then when removing, the dividing strip 1 is lifted out by grasping the support cross bar 13 by hand. After the removed dividing strip 1 is cleaned, it is stored in the warehouse for standby.
[0024] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
