Description

Technical Field

[0001] This utility model relates to the field of post-cast strip demolding technology, specifically a real-time monitoring device for post-cast strip demolding stress. Background Technology

[0002] In construction engineering, post-cast strip concrete is an important structural component, bearing important load-bearing and supporting functions. After the concrete is poured, the formwork needs to be removed. However, during the period from pouring to formwork removal, under certain special circumstances, such as extremely low temperature at the construction site or the use of admixtures such as early-strength agents in the concrete, the formwork removal time may need to be adjusted accordingly. In this case, the strength growth of the post-cast strip concrete should be monitored in real time.

[0003] Currently, the common method for real-time monitoring of post-cast strip demolding stress is to adhere stress sheets to the concrete surface of the post-cast strip and cover them with a protective film for subsequent real-time monitoring. However, due to the influence of the external high temperature and humidity environment, the protective film covering the stress sheets is prone to moisture absorption and aging, resulting in a decrease in adhesion. This indirectly leads to the problem that the protective film covering may fall off and be removed during the demolding period, affecting the normal real-time monitoring of the stress sheets. Therefore, a new real-time monitoring device for post-cast strip demolding stress is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a real-time monitoring device for demolding stress of post-cast strips, so as to solve the problem mentioned in the background art that the existing real-time monitoring devices for demolding stress of post-cast strips are prone to failure due to the peeling of the covering layer, which makes it difficult for the stress sheet to carry out real-time monitoring work normally.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A real-time monitoring device for demolding stress of post-cast strip includes a concrete body of the post-cast strip, an embedded sleeve fixedly installed inside the concrete body of the post-cast strip, a stress plate body glued to the left side of the top surface of the concrete body of the post-cast strip, an insulating flexible pad layer covering the top of the stress plate body, a ceramic cover glued to the outside of the insulating flexible pad layer, a ceramic fiber coating glued to the outer surface of the ceramic cover, side grooves opened on both the left and right sides of the ceramic cover, a limiting plug inserted into the inner side of the side groove, a limiting screw fixedly connected to the bottom end of the limiting plug, and a hollow sleeve and a threaded interface fixedly connected to the upper and lower positions inside the embedded sleeve, respectively.

[0007] Preferably, there are four pre-embedded sleeves, and the spacing between the left and right pre-embedded sleeves is equal to the length of the stress sheet body.

[0008] Preferably, the length of the insulating flexible pad is equal to the length of the stress sheet body, and the thickness of the ceramic fiber coating is less than the thickness of the insulating flexible pad.

[0009] Preferably, the ceramic cover is fitted over the outside of the stress sheet body, and the left side of the stress sheet body is provided with a wiring solder joint. The side of the wiring solder joint away from the stress sheet body is electrically connected to a lead wire that passes through the side opening of the ceramic cover.

[0010] Preferably, the limiting plug extends downward through the pre-reserved slot on the side of the ceramic cover and is inserted into the interior of the hollow sleeve. The limiting screw is inserted into the hollow sleeve and extends into the interior of the pre-embedded sleeve. The limiting screw and the threaded interface are positioned vertically relative to each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inclusion of an insulating flexible pad, a ceramic cover, a ceramic fiber coating, a side groove, a limiting insert, a limiting screw, a pre-embedded sleeve, a hollow sleeve, and a threaded interface facilitates the use of the real-time stress monitoring device for post-cast strip demolding when bonded to the surface of the post-cast strip concrete body. The pre-embedded limiting component, consisting of the pre-embedded sleeve, hollow sleeve, and threaded interface, effectively secures the ceramic covering structure (composed of the insulating flexible pad, ceramic cover, ceramic fiber coating, side groove, limiting insert, and limiting screw) to the outside of the stress plate body. This allows for effective coverage and protection of the stress plate body during real-time monitoring. Furthermore, the entire covering protection component, unlike conventional coverings, is less prone to aging and detachment, effectively protecting the stress plate body during demolding and ensuring normal real-time monitoring.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution:

[0019] A real-time monitoring device for demolding stress of post-cast strip includes a post-cast strip concrete body 1, an embedded sleeve 2 fixedly installed inside the post-cast strip concrete body 1, a stress plate body 3 bonded to the top left position of the post-cast strip concrete body 1, an insulating flexible pad 4 covering the top of the stress plate body 3, a ceramic cover 5 bonded to the outside of the insulating flexible pad 4, a ceramic fiber coating 6 bonded to the outer surface of the ceramic cover 5, side grooves 7 on both the left and right sides of the ceramic cover 5, a limiting plug 8 inserted into the inner side of the side groove 7, a limiting screw 10 fixedly connected to the bottom end of the limiting plug 8, and a hollow sleeve 9 and a threaded interface 11 fixedly connected to the upper and lower positions inside the embedded sleeve 2, respectively.

[0020] like Figure 2 and Figure 3 As shown, there are four pre-embedded sleeves 2. The spacing between the two pre-embedded sleeves 2 on the left and right is equal to the length of the stress sheet body 3. When the stress sheet body 3 is bonded, the four pre-embedded sleeves 2 can play a certain auxiliary limiting role. The length of the insulating flexible pad 4 is equal to the length of the stress sheet body 3. The thickness of the ceramic fiber coating 6 is less than the thickness of the insulating flexible pad 4. The insulating flexible pad 4 will play a role in pressure resistance and insulation protection for the stress sheet body 3. At the same time, the ceramic fiber coating 6 can reduce the influence of the external temperature on the stress sheet body 3 by utilizing its good low thermal conductivity.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, the ceramic cover 5 is sleeved on the outside of the stress plate body 3. The left side of the stress plate body 3 is provided with a wiring solder joint 12. The side of the wiring solder joint 12 away from the stress plate body 3 is electrically connected to a lead wire 13 that passes through the side opening of the ceramic cover 5. This structure facilitates the external connection of the stress plate body 3 to the monitoring system so that the real-time monitored data can be transmitted to the monitoring system. The limiting plug 8 extends downward through the reserved hole groove on the side of the ceramic cover 5 and is inserted into the interior of the hollow sleeve 9. The limiting screw 10 is inserted into the hollow sleeve 9 and extends into the interior of the pre-embedded sleeve 2. The limiting screw 10 and the threaded interface 11 are arranged vertically relative to each other. The spiral connection between the limiting screw 10 and the threaded interface 11 and the fitting and snapping of the upper end of the limiting plug 8 and the hollow sleeve 9 can provide double limitation for the assembly and installation of the ceramic cover 5.

[0022] Workflow: The post-cast strip concrete body 1 in this utility model is mainly a concrete structure formed by pouring an appropriate amount of concrete slurry. Before using the device, it is necessary to ensure that the lead wire 13 is connected to the monitoring main control system. When the pouring work of the post-cast strip concrete body 1 is completed, and the post-cast strip demolding stress real-time monitoring device is used, since four pre-embedded sleeves 2 are pre-cast and embedded in the post-cast strip concrete body 1, forming four points, the pre-adhesive plane defined by the four pre-embedded sleeves 2 is first cleaned, and an appropriate amount of adhesive is applied. With the assistance and constraint of the four pre-embedded sleeves 2, the stress sheet body 3 is accurately adhered to the defined pre-adhesive plane. Then, with the inner and outer dimensions adapted, the ceramic cover 5 is covered and fitted onto the outside of the stress sheet body 3. The limiting plug 8 will be aligned with the inlet position of the pre-embedded sleeve 2. Correspondingly, the insulating flexible pad 4 will be attached to the stress sheet body 3 to provide flexible compression protection. Then, with the hollow fit of the groove, the limiting plug 8 will be screwed down to adjust the limiting plug 8. The upper end of the limiting plug 8 will gradually extend completely into the hollow sleeve 9. The limiting screw 10 at the lower end of the limiting plug 8 will be connected to the threaded interface 11 to secure the assembly of the package cover. At this time, the ceramic covering structure composed of the insulating flexible pad 4, ceramic cover 5, ceramic fiber film 6, side groove 7 and limiting plug 8 can be assembled and installed. This allows the device to replace the conventional simple film covering method to effectively cover and protect the stress sheet body 3 during the later real-time monitoring of the stress of the post-cast concrete body 1 through the stress sheet body 3, and isolate the stress sheet body 3 from the direct influence of the external high temperature and high humidity environment.

[0023] 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.
