Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology, specifically to a positioning mold for thin-layer concrete strip application in culverts. Background Technology

[0002] In municipal drainage, farmland irrigation and highway culvert projects, in order to ensure the airtightness of the pipes during the connection process, it is necessary to apply a mortar sealant to the gap between the two culvert sections. This involves filling and smoothing the annular gap between the culvert sections with mortar to form a waterproof protective strip.

[0003] The existing construction process mostly involves construction workers using plastering tools to apply mortar around the outer wall of the pipe, and then leveling the mortar based on their experience. During this process, it is difficult for construction workers to control the width and thickness of the mortar strip, easily resulting in inconsistent strip widths and uneven edges. To address this, we have proposed a positioning mold for thin-layer concrete mortar strips in culverts. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a positioning mold for thin-layer concrete lining in culverts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a positioning mold for thin-layer concrete grouting in culverts, comprising positioning rings consisting of two connecting blocks respectively fitted around the outside of two culverts; a scraping assembly comprising a scraper 1 set between the two positioning rings for scraping off excess mortar, a receiving groove opened on the inner side of scraper 1, and a scraper 2 slidably inserted into the receiving groove for adjusting the overall length of scraper 1; both scraper 1 and scraper 2 are rotatably connected to the outer sides of ...

[0006] Furthermore, bolts are threaded through both ends of the connecting block located on one side of the culvert, and bolts are threaded through both ends of the connecting block located on the other side of the culvert. Through holes are opened at both ends of the connecting block located on the other side of the culvert. The tail end of the bolt is movably passed through the adjacent through hole and threaded with a nut. Through the operation of the above components, it is convenient for construction workers to remove the connecting block from the outside of the culvert.

[0007] Furthermore, the adjustment assembly includes a positioning groove on the outside of the positioning ring, a positioning block slidably inserted into the positioning groove for adjusting the position of the positioning ring, and a lead screw set on the outside of the gap between the two culverts. The positioning block has a connecting hole, and the lead screw is slidably inserted into the connecting hole. Both ends of the connecting hole are provided with nuts threaded onto the outer wall of the lead screw for fixing the position of the positioning block. By operating the adjustment assembly, the position of the positioning ring can be easily adjusted and fixed by construction personnel, and the scraper blades can be positioned to prevent them from shifting during rotation.

[0008] Furthermore, both ends of the lead screw are fixed with support plates whose bottom ends are fixed to the ground for supporting the lead screw. The lead screw can be supported by the support plates.

[0009] Furthermore, the positioning grooves on the two connecting blocks are connected, and the positioning grooves are misaligned with the bolts. By using the positioning grooves that are misaligned with the bolts, the bolts can be prevented from interfering with the rotation of the connecting blocks.

[0010] Furthermore, the scraper blades one and two are at the same horizontal level on the side closest to the culvert, and the mortar in the mortar strip can be scraped off simultaneously by the scraper blades one and two being at the same horizontal level.

[0011] Furthermore, a handle for rotating the screw is fixed at the end of the screw away from the culvert. By rotating the handle, the screw can be rotated.

[0012] Furthermore, the bottom side of the culvert is provided with a plurality of bearing blocks for supporting the culvert. The bottom end of the bearing block is fixed with a plurality of support columns whose bottom ends are fixed to the ground for supporting the bearing block. The bearing block and the positioning ring are staggered. The bearing block and the support columns can support the culvert and improve the stability of the culvert.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention allows construction workers to easily fill and smooth the annular gap between two culverts, helps them control the width of the mortar strip, and facilitates the removal of excess mortar from the mortar strip according to construction needs, resulting in high workability.

[0014] 2. This invention can help construction workers control the thickness of the mortar strip and facilitates the disassembly and recycling of the mold after use, making it convenient to use. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Combination Figure 1 and Figure 2 The positioning mold for thin-layer concrete troweling in this embodiment includes positioning rings consisting of two connecting blocks 2 respectively fitted outside the two culverts 1. The scraping assembly includes a scraper 7 set between the two positioning rings for scraping off excess mortar, a receiving groove 8 opened inside the scraper 7, and a scraper 9 slidably inserted inside the receiving groove 8 for adjusting the overall length of the scraper 7. Screws 10 are rotatably connected to the outer sides of the scraper 7 and the scraper 9. The screws 10 are threaded onto the outer side of the screws 10 and are fitted with mounting blocks 11 fixed on adjacent connecting blocks 2.

[0019] The implementation principle of the positioning mold for thin-layer concrete grouting in this embodiment is as follows: When grouting is required at the gap between two culverts 1, positioning rings composed of two connecting blocks 2 can be respectively fitted onto the opposite ends of the two culverts 1. The positioning rings are displaced, and the position of the positioning rings outside the culverts 1 can be adjusted. When the lengths of the two positioning rings from the gap between the two culverts 1 are the same, the construction worker can use a plastering tool to apply mortar around the outer wall of the pipe to the gap between the two culverts 1. Then, the connecting block 2 is pushed, causing the connecting block 2 to rotate, which in turn causes the mounting block 11 to rotate, and the screw 1... Rotating screw 10 causes scraper 7 and scraper 9 to rotate, allowing excess mortar in the mortar strip to be scraped away, thus leveling the mortar strip. Rotating screw 10 causes it to move through the threaded engagement with mounting block 11, which in turn moves scraper 7 and scraper 9. This allows adjustment of the positions of scraper 7 and scraper 9, thereby adjusting the thickness of the mortar strip. When the two positioning rings move, they will also move scraper 7 and scraper 9, making them fit with the positioning rings.

[0020] Example 2: Combination Figure 3 This embodiment is further improved on the basis of embodiment 1 in that: the connecting block 2 on one side of the culvert 1 is threaded with bolts 13 at both ends, and the connecting block 2 on the other side of the culvert 1 is provided with through holes at both ends. The tail end of the bolt 13 is movably passed through the adjacent through hole and threaded with a nut 14. Through the cooperation of the bolt 13 and the nut 14, the two connecting blocks 2 can be fixed to the outside of the culvert 1. When it is necessary to remove the positioning ring formed by the two connecting blocks 2 from the outside of the culvert 1, the nut 14 can be rotated. Through the cooperation of the nut 14 and the bolt 13, the nut 14 is moved. When the nut 14 is removed from the outside of the bolt 13, the bolt 13 is rotated and moved. When the bolt 13 is separated from the connecting block 2, the connecting block 2 can be removed from the outside of the culvert 1.

[0021] Example 3: Combination Figure 4 and Figure 5This embodiment, based on Embodiment 1, further improves upon the following: the adjustment assembly includes a positioning groove 3 on the outside of the positioning ring, a positioning block 5 slidably inserted into the positioning groove 3 for adjusting the position of the positioning ring, and a lead rod 4 disposed on the outside of the gap between the two culverts 1. The positioning block 5 has a connecting hole, and the lead rod 4 is slidably inserted into the connecting hole. Both ends of the connecting hole have nuts 6 threadedly fitted onto the outer wall of the lead rod 4 for fixing the position of the positioning block 5. Rotating the nuts 6 causes them to move due to the threaded engagement between the nuts 6 and the lead rod 4. When the nuts 6 separate from the positioning block 5... The positioning block 5 can be pulled, and through the sliding engagement of the connecting hole and the screw 4, the positioning block 5 is moved. Through the engagement of the positioning block 5 and the positioning groove 3, the positioning ring is moved. At this time, the position of the positioning ring outside the culvert 1 can be adjusted. When the length of the two positioning rings from the gap between the two culverts 1 is the same, the nut 6 is rotated. Through the thread engagement of the nut 6 and the screw 4, the nut 6 is moved. When the nut 6 abuts against the positioning block 5, the position of the positioning ring is fixed. The construction worker can use a plastering tool to apply mortar around the outer wall of the pipe to the gap between the two culverts 1.

[0022] Both ends of the lead screw 4 are fixed with support plates 17 whose bottom ends are fixed to the ground for supporting the lead screw 4. The lead screw 4 can be supported by the support plates 17.

[0023] The positioning grooves 3 on the two connecting blocks 2 are connected and the positioning grooves 3 are offset from the bolts 13. By using the positioning grooves 3 that are offset from the bolts 13, the bolts 13 can be prevented from interfering with the rotation of the connecting blocks 2.

[0024] Scraper 7 and scraper 9 are at the same horizontal level on the side closest to culvert 1. By using scraper 7 and scraper 9 at the same horizontal level, the mortar in the mortar strip can be scraped off simultaneously.

[0025] A handle 12 is fixed at the end of the screw 10 away from the culvert 1 for driving the screw 10 to rotate. By rotating the handle 12, the screw 10 can be driven to rotate.

[0026] The bottom side of the culvert 1 is provided with multiple bearing blocks 15 for supporting the culvert 1. The bottom end of the bearing block 15 is fixed with multiple support columns 16 whose bottom ends are fixed on the ground for supporting the bearing block 15. The bearing block 15 is offset from the positioning ring. The bearing block 15 and the support columns 16 can support the culvert 1 and improve the stability of the culvert 1.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
