Description

Technical Field

[0001] This utility model belongs to the field of post-pouring strip protection technology, specifically relating to a post-pouring strip protection device. Background Technology

[0002] Post-cast strips are temporary concrete strips installed during building construction to prevent harmful cracks in the concrete structure due to shrinkage, settlement, or temperature changes. They need to be sealed by a second pour after a certain period of time following the completion of the main structure. Different forms exist depending on their effects and purposes. For example, settlement post-cast strips are mainly used to alleviate differential settlement between the main building and the podium, and are sealed after the main structure has stabilized. Shrinkage post-cast strips are mainly used to reduce early shrinkage stress and temperature stress in concrete through segmented pouring.

[0003] Taking the post-settlement strip as an example, during construction, a certain distance needs to be reserved between the building and other concrete structures. At this time, the post-settlement strip formed between the concrete structure of the building and other concrete structures has a certain depth. If it is not covered or protected, it will not only affect the movement of construction equipment and vehicles, but also cause people to fall. Moreover, it will also cause water accumulation, rainwater or waste materials (garbage, stones, etc.) to enter due to exposure, which will require cleaning when pouring the post-settlement strip later, increasing the workload and difficulty.

[0004] Therefore, effective protection is required before the post-pouring strip is poured. The main form of protection is to use slabs to cover the post-pouring strip between the concrete structure and other concrete structures at the building location. However, in this form, the slabs are not easy to fix and are prone to shifting under the influence of vibrations caused by being stepped on or passing vehicles. Moreover, it cannot prevent water accumulation and rainwater from entering the post-pouring strip. It only serves to allow construction equipment, vehicles and personnel to move. Summary of the Invention

[0005] Based on this, this application provides a post-cast strip protection device to solve the technical problem that ordinary cover plates in the prior art are prone to displacement under the influence of vibration caused by being stepped on or passing by vehicles, and also cannot prevent water accumulation and rainwater from entering the post-cast strip.

[0036] Please refer to Figures 1 to 8 In one specific embodiment of this application,

[0037] A post-cast strip protection device for waterproofing and covering the post-cast strip, comprising:

[0038] A water wall assembly that can cover the corners of the concrete in the post-cast strip to prevent water from the ground from flowing into the post-cast strip;

[0039] A quick-installation assembly that can connect the water wall assembly to the corner of the post-pouring strip;

[0040] The water wall assembly includes two vertical plates 101, and a flat plate 102 is fixed to the middle of the outer side of each vertical plate 101. The flat plate 102 is perpendicular to the vertical plate 101. The quick-installation assembly can connect the two vertical plates 101 to the inner side of the corner of the post-pouring strip respectively.

[0041] A cover assembly, which is fastened to two upright plates 101, is used to cover the post-pouring strip;

[0042] In the above section, during operation, the water wall component is connected to the corner of the post-cast strip (the corner of the concrete structure of the building and other concrete structures) using quick-installation components. Then, the covering component is fastened to the water wall component to cover the post-cast strip formed between the concrete structure of the building and other concrete structures. Therefore, the quick-installation component is a bolt, screw, or other connector that can connect the water wall component to the corner of the post-cast strip; the covering component is a steel plate or other device that can be fastened to the water wall component to cover the post-cast strip.

[0043] When covering and protecting the post-pouring strip, the outer sides of the two vertical plates 101 are respectively attached to the inner side of the corner (the inner side of the corner mentioned below, that is, the inner side of the corner of the concrete structure at the building location or the inner side of the corner of other concrete structures), and the flat plate 102 is in contact with the upper side of the corner (the upper side of the corner mentioned below, that is, the upper side of the corner of the concrete structure at the building location or the upper side of the corner of other concrete structures). Then, the vertical plates 101 are connected to the inner side of the corner through the quick-installation assembly. At this time, the upper half of the two vertical plates 101 (the part of the vertical plates 101 that extends beyond the flat plate 102 in the vertical direction) is higher than the surface of the concrete structure. Then, the covering assembly is fastened to the two vertical plates 101 to cover the post-pouring strip.

[0044] As described above, the upper part of the vertical plate 101, which is higher than the surface of the concrete structure, can be used to block the water or rainwater flowing on the surface of the concrete structure, preventing the water or rainwater from flowing into the post-cast strip. At the same time, the vertical plate 101 can block the water or rainwater flowing laterally while covering the post-cast strip from above by the covering component to prevent rainwater from entering and personnel and equipment from passing by.

[0045] Specifically, an embodiment of the overlay component in the above process is provided:

[0046] The cover plate 301 has sidewalls that bend downwards on both sides. The cover plate 301 is fastened to the outer upper end of the two upright plates 101 by the two sidewalls and is located above the flat plate 102.

[0047] During construction, after the two vertical plates 101 are connected to the concrete structure using the quick-installation assembly, the cover plate 301 can be fastened to the upper side of the two vertical plates 101. The connection of the cover plate 301 is achieved by the mutual friction and compression between the downward curved sidewalls of the cover plate 301 and the upper side of the two vertical plates 101. The cover plate 301 covers the post-pouring strip below and also covers the quick-installation assembly below.

[0048] The above-mentioned method and structure enable rapid covering and protection of the post-pouring strip, and the fastening and clamping mechanism facilitates subsequent disassembly.

[0049] Furthermore, the covering assembly includes a cover plate 301 and a plurality of triangular plates 303 fixed on both sides of the cover plate 301. The plurality of triangular plates 303 form a slope on the side of the cover plate 301, which can guide and transition when the vehicle passes over the cover plate 301.

[0050] The ends of multiple covering components can be connected to increase the coverage length of the post-pouring strip. The covering component includes a connecting part that can connect and tighten the ends of two adjacent covering components.

[0051] Multiple covering components can be fastened to the two upright plates 101 in the water wall component to increase the length to cover the post-pouring strip. After covering, the ends of two adjacent covering components are connected and tightened through the connecting part to make the ends of the two covering components more tightly connected and improve the waterproof effect. It can also be sealed and waterproofed by filling with sealant or sealant.

[0052] In addition, in order to facilitate the interconnection between multiple cover components, in this application, the connecting part includes an ear plate 302, which is fixed to the end of the cover plate 301, and the two ear plates 302 at the ends of two adjacent cover plates 301 are connected by bolts.

[0053] When connecting the two cover plates 301, after fastening the two cover plates 301 onto the upper side of the two upright plates 101, the two ear plates 302 at the ends of the two adjacent cover plates 301 are connected by bolts. By tightening the bolts, the bolts clamp the two ear plates 302, thereby achieving close contact between the ends of the two cover plates 301.

[0054] The above method can not only connect multiple cover plates 301, but also minimize the gaps generated after the ends of the cover plates 301 come into contact through the clamping of bolts, thereby improving the sealing effect.

[0055] In the above process, the vertical plate 101 is connected to the corner of the post-cast strip using quick-installation components, which effectively blocks accumulated water and rainwater, preventing ground water from flowing into the post-cast strip. However, there are gaps at the contact points between the vertical plate 101 and the corner of the post-cast strip. Under prolonged immersion in water, there is a possibility that water may seep through these gaps and enter the post-cast strip.

[0056] Therefore, sealing parts 103 are provided between the flat plate 102 and the concrete corner, between the vertical plate 101 and the concrete corner, and between the side wall of the cover plate 301 and the outer side of the upper end of the vertical plate 101. The sealing part 103 is a facility used to fill the gap between the vertical plate 101 and the inner side of the corner, such as sealant or sealant.

[0057] After the upright plate 101 is connected to the inside of the corner by the quick-installation assembly, the sealing part 103 can be filled into the gap between the upright plate 101 and the inside of the corner, thereby achieving the effect of sealing the gap, sealing the gap between the upright plate 101 and the inside of the corner, preventing water from seeping in, and improving waterproofing.

[0058] Similarly, the sealing part 103 can seal the gap between the cover assembly and the water wall assembly. That is, after the cover assembly is fastened to the two upright plates 101, the gap between the cover assembly and the two upright plates 101 can also be filled and sealed by the sealing part 103, which further improves the waterproof capability between the cover assembly and the two upright plates 101 and prevents water from seeping in from the gap between the cover assembly and the two upright plates 101 after the entire device has been submerged.

[0059] Specifically, an embodiment of the sealing part 103 described above is provided:

[0060] The sealing part 103 is a sealing strip or a sealing pad; taking the sealing strip as an example, that is, the sealing strip is fixed on the upright plate 101, and when the covering component and the upright plate 101 are fastened together, the mutual compression between the two can be used to fill the gap between the covering component and the upright plate 101 to complete the sealing and waterproofing; similarly, the gap between the upright plate 101 and the inner side of the corner is also filled with the sealing strip for waterproofing.

[0061] As mentioned above, quick-installation components are bolts, screws, or other connectors that allow the water wall component to be attached to the corner of the post-cast strip. For example, if the quick-installation component is a bolt or screw, when fixing the water wall component, holes are drilled on the underside of the vertical plate 101 (that is, the part of the vertical plate 101 below the flat plate 102), and bolts or screws are inserted through the holes to connect to the concrete, thus connecting the vertical plate 101 to the inside of the corner; or holes are drilled on the flat plate 102, because the flat plate 102 contacts the upper side of the concrete corner, and bolts or screws can be used to connect it to the concrete, thereby fixing the position of the flat plate 102 and achieving the connection between the water wall component and the concrete. While this method of connecting concrete structures is effective, drilling holes in either the underside of the vertical plate 101 or the flat plate 102 requires opening holes in the corresponding locations in the concrete to connect bolts or screws. Drilling or chiseling in the concrete structure can reduce the strength of the concrete part connected to the water wall component, making it prone to cracking in the surrounding concrete or breakage around the bolts or screws. It can also expose the bolts or screws to the outside environment, making them susceptible to rusting in rainwater, stagnant water, or damp conditions, thus reducing the connection strength and causing bolt corrosion and loosening, leading to problems in the connection between the water wall component and the concrete structure.

[0062] Therefore, this application provides a specific embodiment of the quick-installation component:

[0063] The quick-assembly assembly includes a threaded tube 201 and a lead screw 203 connected inside the threaded tube 201. A nut 202 is fixed on the outer wall of the threaded tube 201. A locking block 204 is formed on the outer end of the lead screw 203. The locking block 204 and the outer end of the threaded tube 201 respectively contact the inner side of the two vertical plates 101.

[0064] When connecting the water wall assembly to the concrete structure, the flat plate 102 is placed on the upper side of the concrete corner, with the lower side of the upright plate 101 attached to the inner side of the concrete corner. Then, the quick-assembly assembly is horizontally erected between two upright plates 101 within the same water wall assembly, with the threaded tube 201 and the lead rod 203 perpendicular to the two upright plates 101. Initially, the lead rod 203 is located inside the threaded tube 201. During use, one hand rotates the threaded tube 201 while the other hand holds the lead rod 203 still, allowing the lead rod 203 to extend beyond the threaded tube 201 until the end of the threaded tube 201 contacts the inner side of one upright plate 101, and the end of the lead rod 203 contacts the inner side of the other upright plate 101. Continuing to rotate the threaded tube 201 further increases the overall length of the threaded tube 201 and the lead rod 203. By using the threaded tube 201 and the screw rod 203 to press the two upright plates 101 together, the two upright plates 101 are pressed against the inside of the corner of the concrete. This allows for the connection between the water wall component and the concrete structure without drilling holes in the upright plates 101, the flat plate 102, or the concrete. This method is not only convenient to install, but also easier to disassemble than bolts. Simply rotating the threaded tube 201 in the opposite direction will retract the screw rod 203 back into the threaded tube 201. At the same time, as the threaded tube 201 rotates, the force exerted by the threaded tube 201 and the screw rod 203 on the two upright plates 101 increases, making it increasingly difficult to rotate the threaded tube 201. At this point, the worker can use a wrench to engage the nut 202 to continue rotating the threaded tube 201, thus saving the worker's effort.

[0065] This design not only enables convenient installation and disassembly, but also allows for the recycling and reuse of quick-install components compared to traditional bolt and screw connectors. After installation, the quick-install components are protected by a cover component that snaps onto the water wall component, preventing damage from long-term exposure to wind, sun, or rain. In other words, the entire quick-install component is located in the post-pouring strip below the cover component, and is not exposed to the outside world, thus ensuring stable compression of the water wall component.

[0066] Furthermore, when the lead screw 203 and the threaded tube 201 contact the vertical plate 101, they are prone to misalignment or falling off relative to the vertical plate 101 due to hand tremors or shaking during operation.

[0067] The water wall assembly has two upright plates 101, one of which has a retainer 104 formed on its inner side, and the other has a sleeve 105 formed on its inner side; the threaded tube 201 in the quick-install assembly can be inserted into the sleeve 105 and can rotate, and the retainer 204 can be inserted into the retainer 104 and cannot rotate.

[0068] In other words, during operation, when installing the water wall assembly, the clamping sleeves 104 and sleeves 105 on the inner sides of the two upright plates 101 are aligned horizontally (the clamping sleeves 104 and sleeves 105 are kept on the same axis). Then, the outer end of the threaded tube 201 is inserted into the sleeve 105 and the threaded tube 201 is rotated continuously, so that the screw 203 in the threaded tube 201 extends out. The screw 203 drives the clamping block 204 to be inserted into the clamping sleeve 104 to achieve quick positioning. This makes the quick-installation assembly perpendicular to the two upright plates 101. Under the restriction of the sleeve 105, the threaded tube 201 and the clamping block 204 will not fall off. After positioning, the worker only needs to rotate the threaded tube 201 with one hand to press the two upright plates 101 together.

[0069] This reduces the difficulty of operation for workers and avoids situations where the lead screw 203 and threaded tube 201 may shift or fall off relative to the vertical plate 101 due to hand tremors or shaking during operation.

[0070] Specifically, the length of the post-pouring strip is designed in advance according to the site dimensions. As described in the above process, in order to reduce the strength when protecting the post-pouring strip, multiple water wall components are provided in this application, which can be connected. As mentioned in this application, the end of the vertical plate 101 is provided with a connecting component. The connecting component can connect two adjacent vertical plates 101, increasing the coverage length of the edge concrete corner of the post-pouring strip. The connecting component is a bolt, weld or splicing structure, snap-fit ​​structure, etc. that can connect two vertical plates 101 that are connected at the end.

[0071] Furthermore, after the vertical panels 101 in the water wall assembly are connected, sealant or sealant is used to fill the gap between the two mating vertical panels 101 to achieve a seal and waterproofing.

[0072] It can be connected according to the actual dimensions of the site to meet the length requirements.

[0073] Additionally, see Figure 9 Here is another embodiment for the above process:

[0074] Figure 9 The structure in the above scheme is one of the implementation methods. The patterned steel plate 401 is the covering component, and the angle steel 403 and the waterproof membrane 404 are the water wall components to prevent water from entering the post-pouring strip. Several square tubes 402 are welded on the lower end face of the patterned steel plate 401. The length of the square tubes 402 is less than the width of the patterned steel plate 401. Angle steel 403 is fixed on both sides of the lower end face of the patterned steel plate 401 along the length direction. The lower end of the vertical side of the angle steel 403 is wrapped with a detachable waterstop strip 405. The waterstop strip 405 can be made of elastic material (such as rubber).

[0075] When using it, the waterproof membrane 404 is laid on the upper side of the corner of the concrete, and the patterned steel plate 401 is covered on the post-pouring strip. At this time, the square tube 402 is located between the two angle steels 403 to improve the strength of the patterned steel plate 401 and prevent bending deformation. At this time, the waterstop strips 405 at the lower ends of the two angle steels 403 contact the waterproof membrane 404, and the weight of the patterned steel plate 401, square tube 402 and angle steel 403 causes the waterstop strips 405 to undergo elastic deformation and make tight contact with the waterproof membrane 404 to complete the seal.

[0076] The use of angle steel 403, waterproof membrane 404, and waterstop strip 405 can effectively block water flow and prevent water from entering the post-cast strip. At the same time, the use of square tube 402 can improve the strength of patterned steel plate 401 and prevent deformation of patterned steel plate 401 when vehicles, equipment, and personnel walk on it. In addition, the lower ends of waterstop strip 405 and angle steel 403 are detachable, which can be easily replaced and can be recycled and reused after use, reducing the cost of use.

[0077] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
