Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a composite post-cast strip cover plate. Background Technology

[0002] In construction engineering, post-cast strips are an important structural measure to address cracks in concrete structures caused by temperature shrinkage or settlement differences. Post-cast strip cover plates effectively cover the strip, forming a protective barrier that prevents construction debris, rainwater, and other impurities from entering, avoiding steel reinforcement corrosion and joint contamination, ensuring the cleanliness of the post-cast strip's interior, and guaranteeing the quality of subsequent pouring.

[0003] Currently, the commonly used post-cast strip cover plates are usually formed by pouring concrete to create a single unit or by welding, which ensures ideal connection strength and effectively prevents rainwater from entering the post-cast strip through the gaps between adjacent cover plates. However, this connection method leads to difficulties in dismantling, and subsequent removal can easily damage the post-cast strip cover plate or surrounding structures. Utility Model Content

[0004] To facilitate the removal of the post-cast strip cover and reduce the probability of damaging the post-cast strip cover or surrounding structures during removal, this application provides a combined post-cast strip cover.

[0005] The combined post-pouring strip cover plate provided in this application adopts the following technical solution: A combined post-cast strip cover plate includes water-retaining sills disposed on both sides of the post-cast strip and a cover plate body disposed on the water-retaining sills. The cover plate body includes a plurality of unit plates and a connecting structure connecting adjacent unit plates. The connecting structure includes an upper protrusion, a lower protrusion, and a locking structure for locking the upper protrusion and the lower protrusion. Each unit plate has a lower groove formed at the bottom of the upper protrusion and an upper groove formed at the top of the lower protrusion. When two adjacent unit plates are connected, the upper protrusion is inserted into the upper groove and the lower protrusion is inserted into the lower groove.

[0006] By adopting the above technical solution, since the main body of the post-pouring strip cover plate includes several unit plates and a joint structure connecting adjacent unit plates, the upper convex part and the lower convex part in the joint structure can be locked by a locking structure. When two adjacent unit plates are connected, the upper convex part can be inserted into the lower groove formed at the bottom of the upper convex part of the unit plate, and the lower convex part can be inserted into the upper groove formed at the top of the lower convex part of the unit plate, so that the adjacent unit plates are tightly joined, which facilitates the removal of the post-pouring strip cover plate when needed for subsequent construction, and also helps to reduce the probability of damaging the post-pouring strip cover plate or surrounding structures during removal.

[0007] Optionally, the sidewall of the upper protrusion is inclined downward toward the upper groove, and the sidewall of the lower protrusion is inclined upward toward the lower groove.

[0008] By adopting the above technical solution, the sidewall of the upper convex part is inclined downward towards the direction of the upper groove, and the sidewall of the lower convex part is inclined upward towards the direction of the lower groove, so that the connection strength is ideal after the adjacent unit plates are joined, and the probability of relative movement in the vertical direction between adjacent unit plates is reduced.

[0009] Optionally, the locking structure includes a plunger hole in the lower protrusion, a ball spring plunger installed in the plunger hole, and an annular limiting hole in the bottom of the upper protrusion for the plunger ball of the ball spring plunger to engage.

[0010] By adopting the above technical solution, the annular limiting hole at the bottom of the upper convex part in the locking structure can cooperate with the ball spring plunger installed in the plunger hole of the lower convex part, which can reduce the probability of relative horizontal movement between adjacent unit plates.

[0011] Optionally, the joining structure further includes a capping waterproof layer for covering the gap between the upper protrusion and the upper groove.

[0012] By adopting the above technical solution, the waterproof layer can cover the gap between the upper protrusion and the upper groove, effectively preventing rainwater from entering the post-pouring strip through the gap between adjacent unit plates, which helps to enhance the waterproof performance of the combined post-pouring strip cover plate.

[0013] Optionally, the unit plate has a fixing groove near the upper protrusion and the upper groove, and the bottom of the cover waterproof layer has a fixing protrusion that engages with the fixing groove.

[0014] By adopting the above technical solution, the fixing groove opened near the upper protrusion and upper groove of the unit plate is engaged with the fixing protrusion at the bottom of the cover waterproof layer, so that the cover waterproof layer can be firmly installed on the unit plate, which helps to enhance the stability of the cover waterproof layer.

[0015] Optionally, the waterproof cover layer has a guide slope that slopes downwards in all directions, and the length of the waterproof cover layer is equal to the width of the unit plate.

[0016] By adopting the above technical solution, the guide slope of the waterproof layer can guide rainwater and other impurities to the surrounding area to avoid water accumulation. At the same time, the length of the waterproof layer is equal to the width of the unit panel, which can more comprehensively protect the connection between adjacent unit panels and help improve waterproof performance.

[0017] Optionally, the bottom of the upper convex portion is provided with a guide strip, and the top of the lower convex portion is provided with a guide groove that cooperates with the guide strip.

[0018] By adopting the above technical solution, a guide strip is set at the bottom of the upper convex part and a guide groove is set at the top of the lower convex part. When adjacent unit plates are connected, they can play a positioning and guiding role, so that the upper and lower convex parts can be inserted into the corresponding grooves more accurately and smoothly, thereby improving assembly efficiency and accuracy.

[0019] Optionally, the top of the water-retaining sill is provided with a threaded hole, and the unit plate is provided with a through hole for mounting bolts that mate with the threaded hole.

[0020] By adopting the above technical solution, the connection structure between the water-retaining sill and the unit plate is disclosed. The water-retaining sill and the unit plate are connected by a threaded structure, which makes the connection strength of the two ideal, thereby improving the overall structural stability of the combined post-pouring strip cover plate and facilitating the removal of the water-retaining sill and the unit plate when needed for subsequent construction.

[0021] Optionally, the bottom of the unit plate is slidably installed with wooden beams for abutting the concrete at both ends of the post-pouring strip. The unit plate is provided with a sliding groove along the width direction for the wooden beams to slide. The wooden beams have sliders adapted to the sliding grooves. The end face of the sliding groove away from the water-retaining sill is provided with an elastic element that abuts against the wooden beams.

[0022] By adopting the above technical solution, wooden beams are slidably installed at the bottom of the unit board, and under the action of the elastic element, the wooden beams can stably abut against the concrete at both ends of the post-pouring strip. Regardless of whether the concrete structure expands or contracts due to temperature, the wooden beams can tightly fit the concrete at both ends of the post-pouring strip, which helps to further enhance the waterproof performance.

[0023] Optionally, the cover plate body has side plates on both sides that fit against the outer side of the water barrier, and a sealing waterproof strip is provided at the joint between the side plates and the water barrier.

[0024] By adopting the above technical solution, side plates that fit the outer side of the water-retaining sill are set on both sides of the main body of the cover plate, and a sealing waterproof strip is set at the joint between the side plate and the water-retaining sill. This can effectively prevent rainwater from entering the post-pouring strip from the joint between the two, which helps to enhance the sealing performance between the post-pouring strip cover plate and the water-retaining sill. This can better protect the internal environment of the post-pouring strip and prevent the internal steel bars from corroding, thus ensuring the quality of subsequent pouring.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. A combined post-pouring strip cover plate, which is provided with a water-retaining sill and a cover plate body, and the cover plate body includes several unit plates and a joint structure connecting adjacent unit plates. The joint structure includes an upper protrusion, a lower protrusion and a locking structure for locking the upper protrusion and the lower protrusion, which facilitates the removal of the post-pouring strip cover plate when needed for subsequent construction, and also helps to reduce the probability of damaging the post-pouring strip cover plate or surrounding structures during removal. 2. By setting a waterproof cover layer that covers the gap between the upper protrusion and the upper groove, rainwater can be effectively prevented from entering the post-pouring strip through the gap between adjacent unit plates, which helps to enhance the waterproof performance of the combined post-pouring strip cover plate. 3. By setting a guide strip at the bottom of the upper convex part and a guide groove that cooperates with the guide strip at the top of the lower convex part, the upper and lower convex parts can play a positioning and guiding role when connecting adjacent unit boards, which helps the upper and lower convex parts to be inserted into the corresponding grooves more accurately, thereby improving assembly efficiency and accuracy.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a combined post-pouring strip cover plate. (Refer to...) Figure 1The combined post-pouring strip cover plate includes a water-retaining sill 1 set on both sides of the post-pouring strip and a cover plate body 2 set on the water-retaining sill 1. The cover plate body 2 has side plates 21 on both sides that fit against the outer side of the water-retaining sill 1, and a sealing waterproof strip 22 is set at the joint between the side plates 21 and the water-retaining sill 1, which can effectively prevent rainwater from entering the post-pouring strip from the joint between the two.

[0034] refer to Figure 1 and Figure 2 The cover plate body 2 includes several unit plates 23 and a connecting structure 24 connecting adjacent unit plates 23. The connecting structure 24 includes an upper protrusion 241, a lower protrusion 242, a locking structure 243 for locking the upper protrusion 241 and the lower protrusion 242, and a waterproof covering layer 244. Each unit plate 23 has a lower groove 231 formed at the bottom of the upper protrusion 241 and an upper groove 232 formed at the top of the lower protrusion 242. When two adjacent unit plates 23 are connected, the upper protrusion 241 is inserted into the upper groove 232, and the lower protrusion 242 is inserted into the lower groove 231. Furthermore, the sidewall of the upper protrusion 241 slopes downwards towards the upper groove 232, and the sidewall of the lower protrusion 242 slopes upwards towards the lower groove 231, which helps reduce the probability of relative vertical movement when two adjacent unit plates 23 are connected.

[0035] refer to Figure 1 A wooden beam 235 is slidably mounted on the bottom of the unit plate 23. The unit plate 23 has a sliding groove 236 along its width for the wooden beam 235 to slide. The wooden beam 235 has a slider 2351 adapted to the sliding groove 236. An elastic element 2361, which abuts against the wooden beam 235, is provided on the end face of the sliding groove 236 away from the water-retaining sill 1. In this embodiment, the elastic element 2361 is a spring. The elastic element 2361 causes the wooden beam 235 to tend to slide towards the concrete at both ends of the post-pouring strip, allowing the wooden beam 235 to abut against the concrete at both ends of the post-pouring strip. Regardless of whether the concrete structure expands or contracts due to temperature, the wooden beam 235 can tightly adhere to the concrete at both ends of the post-pouring strip, further enhancing the waterproofing performance.

[0036] refer to Figure 2The locking structure 243 includes a plunger hole 2431 formed in the lower protrusion 242, a ball spring plunger 2432 installed in the plunger hole 2431, and an annular limiting hole 2433 formed at the bottom of the upper protrusion 241 for engaging the plunger ball 24323 of the ball spring plunger 2432. In this embodiment, the axis of the plunger hole 2431 is vertical. The ball spring plunger 2432 includes a plunger housing 24321, a plunger spring 24322 installed in the plunger housing 24321, and a plunger ball 24323 installed in the plunger housing 24321. Under the action of the plunger spring 24322, the plunger ball 24323 always tends to protrude from the plunger housing 24321, so that the plunger ball 24323 can engage in the annular limiting hole 2433 of the upper protrusion 241, thereby locking the adjacent unit plate 23. In this embodiment, the ball spring plunger 2432 is threaded into the plunger hole 2431, and the tail end of the plunger housing 24321 is provided with an internal hexagonal groove 24324 to facilitate the installation of the ball spring plunger 2432 into the plunger hole 2431 using a tool.

[0037] refer to Figure 3 and Figure 4 The bottom of the upper convex part 241 is provided with a guide strip 2411, and the top of the lower convex part 242 is provided with a guide groove 2421 that cooperates with the guide strip 2411. When connecting adjacent unit plates 23, the guide strip 2411 and the guide groove 2421 can play a positioning and guiding role, which helps the upper convex part 241 and the lower convex part 242 to be inserted into the corresponding groove more accurately.

[0038] refer to Figure 2 and Figure 5 The unit panel 23 has fixing grooves 25 near the upper protrusion 241 and the upper groove 232. The bottom of the cover waterproof layer 244 has a fixing protrusion 2441 that engages with the fixing groove 25. The cover waterproof layer 244 also has a guide slope 2442 that slopes downwards in all directions, allowing it to be securely installed on the unit panel 23. The length of the cover waterproof layer 244 is equal to the width of the unit panel 23, and it covers the gap between the upper protrusion 241 and the upper groove 232, effectively preventing rainwater from entering the post-cast strip through the gaps between adjacent unit panels 23.

[0039] refer to Figure 1 and Figure 5 The top of the water-retaining sill 1 is provided with a threaded hole 11, and the unit plate 23 is provided with a through hole 233 that penetrates its upper and lower surfaces. A mounting bolt 234 for cooperating with the threaded hole 11 is provided in the through hole 233. The water-retaining sill 1 and the unit plate 23 are connected by a threaded structure, which has ideal connection strength and is also convenient for the water-retaining sill 1 and the unit plate 23 to be removed when needed for subsequent construction.

[0040] The implementation principle of a combined post-cast strip cover plate according to an embodiment of this application is as follows: The cover plate body 2 of the post-cast strip cover plate includes several unit plates 23 and a connecting structure 24 connecting adjacent unit plates 23. The upper protrusion 241 and the lower protrusion 242 in the connecting structure 24 can be locked by the locking structure 243. When two adjacent unit plates 23 are connected, the upper protrusion 241 can be inserted into the lower groove 231 formed at the bottom of the upper protrusion 241 of the unit plate 23, and the lower protrusion 242 can be inserted into the upper groove 232 formed at the top of the lower protrusion 242 of the unit plate 23, so that the adjacent unit plates 23 are tightly joined. When the post-cast strip cover plate needs to be removed during subsequent construction, the operators can easily separate the unit plates 23 of the post-cast strip cover plate, which helps to reduce the probability of damaging the post-cast strip cover plate or surrounding structures during removal.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
