Description

Technical Field

[0001] This invention belongs to the field of building road and bridge construction technology, specifically relating to a building road and bridge pouring construction process and device. Background Technology

[0002] In the field of road and bridge construction, pouring concrete is a crucial step in building the main structure of a road or bridge. As the core support structure for concrete forming, the performance of the pouring formwork is closely related to the construction quality. During on-site construction, workers first need to assemble the formwork, then pour concrete into the inside of the formwork. After the concrete solidifies, the formwork is removed, thus forming a road or bridge structure that meets the design requirements. Therefore, the splicing accuracy, stability, and sealing of the formwork directly determine the final construction quality and service life of the road or bridge project.

[0003] Existing bridge and road casting formwork mostly uses traditional steel or wooden formwork, which is spliced ​​and fixed by bolts, clips, etc. However, in practical applications, there are problems with unreasonable splicing structure design. The formwork splicing points need to be opened with through bolt holes, which makes it easy for concrete inside the formwork to leak from the bolt holes later. During the casting process, grout leakage is likely to occur, resulting in honeycomb and pitting on the concrete surface, affecting the appearance and strength of the bridge and road structure. In addition, the sealing performance is poor and grout leakage is easy. To address this, the present invention proposes a construction process and device for casting bridge and road structures. Summary of the Invention

[0004] The purpose of this invention is to provide a construction process and apparatus for pouring concrete for buildings, roads, and bridges, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction device for pouring concrete for building roads and bridges, comprising... Multiple bridge and road casting formwork bodies are horizontally spliced ​​together, and the bridge and road casting formwork bodies at both ends are C-shaped structures. After multiple bridge and road casting formwork bodies are spliced ​​together, they form a rectangular frame structure. The splicing structure set between two adjacent bridge and road casting formwork bodies includes a splicing block fixed to one side surface of the bridge and road casting formwork body, a splicing groove opened on the other side surface of the bridge and road casting formwork body corresponding to the splicing block, and an external locking structure set between the splicing block and the splicing groove. The sealing structure set between two adjacent bridge and road casting formwork bodies includes a sealing adhesive plate installed on the inner side of the splice of the two bridge and road casting formwork bodies, and a rectangular sealing groove opened on the inner surface of the bridge and road casting formwork body that is compatible with the sealing adhesive plate.

[0006] Preferably, the external locking structure includes multiple external screws fixed to the outer surface of the splicing block, multiple external notches corresponding to the external screws and opened on the outer surface of the main body of the bridge and road casting template and communicating with the splicing groove, and multiple external locking nuts corresponding to the external screws and set on the outer side of the main body of the bridge and road casting template.

[0007] Preferably, the width of the outer notch is adapted to the diameter of the outer screw, and the inner end of the outer notch is a semi-circle adapted to the outer screw.

[0008] Preferably, the two corners of the splicing block are provided with inclined guide surfaces.

[0009] Preferably, the sealing structure further includes a plurality of integral T-shaped sealing strips disposed on the inner surface of the sealing adhesive plate, and a T-shaped sealing groove formed on the inner wall of the rectangular sealing groove to match the T-shaped sealing strips.

[0010] Preferably, the sealing structure further includes an integral L-shaped extension section disposed at the top of the sealing adhesive plate, a T-shaped limiting head installed at the top of the outer surface of the main body of the bridge and road casting template, and an installation hole opened on the surface of the L-shaped extension section for the T-shaped limiting head to pass through.

[0011] Preferably, both the T-shaped sealing strip and the T-shaped sealing groove have a T-shaped cross-section.

[0012] A construction process using the aforementioned bridge and road casting construction device includes the following steps: Step 1: Construction preparation. Based on the dimensions of the road and bridge pouring section, calculate the quantity and specifications of the main body of the road and bridge pouring formwork. Check the integrity and good condition of the main body of the road and bridge pouring formwork, splicing structure and sealing structure. Clean the inner wall of the main body of the road and bridge pouring formwork to ensure that the surface is free of oil stains and debris. Step 2: Template Assembly. Lay out the lines in the construction area according to the design positions. First, fix the C-shaped main body of the bridge and road casting template at both ends to the preset positions. Then, use a splicing structure to assemble another main body of the bridge and road casting template on one side, embedding the splicing block into the splicing groove. Finally, use an external locking structure to lock and fix it, completing the splicing of the two main bodies of the bridge and road casting template. Repeat the above steps to complete the splicing of all the main bodies of the bridge and road casting template, forming a complete rectangular frame structure. Step 3: Splicing and sealing. Install sealant plates on the inside of the splicing joint of two adjacent bridge and road casting formwork bodies, so that the T-shaped sealant strip is inserted into the T-shaped sealant groove and the L-shaped extension is inserted at the top of the splicing joint of the two bridge and road casting formwork bodies, thereby forming multiple sealing measures on the inside of the splicing joint of the bridge and road casting formwork bodies. Step 4: Concrete Pouring: After the main body of the road and bridge pouring formwork has passed the acceptance inspection, concrete pouring operation is carried out on the inner side of the main body of the road and bridge pouring formwork. During the pouring process, the pouring speed is controlled to avoid excessive lateral pressure on the concrete, which may cause deformation of the main body of the road and bridge pouring formwork. Step 5: Formwork Removal: After the concrete is poured, it must be cured to more than 75% of the design strength before the main formwork of the road and bridge can be removed. First, remove the sealing structure, then remove the outer locking structure. Disassemble the main formwork of the road and bridge one by one, clean the concrete residue on the surface of the main formwork, and check the integrity of the splicing structure and sealing structure for reuse.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: The construction process and apparatus for building bridges and roads, through innovative splicing structures and sealing designs, avoid the need for through-hole bolt holes at the formwork splicing points, fundamentally solving the problems of concrete leakage from bolt holes and grout leakage during pouring. This effectively prevents defects such as honeycomb and pitting on the concrete surface, significantly improving the appearance quality of the bridge and road structure, making it smoother and more aesthetically pleasing. Simultaneously, it enhances the sealing performance of the formwork, reduces cement grout loss, ensures the density and strength of the concrete, and greatly improves the durability and service life of the bridge and road structure. Furthermore, the improved formwork splicing method is simple to operate, improves splicing accuracy and stability, reduces subsequent repair work, lowers construction costs, and accelerates construction progress, providing a more efficient and high-quality solution for building bridge and road construction.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0016] Please see Figures 1 to 7 As an embodiment of the present invention, this embodiment provides the following technical solution: a construction device for pouring concrete for building roads and bridges, comprising... Multiple bridge and road casting formwork bodies 1 are horizontally spliced ​​together, and the bridge and road casting formwork bodies 1 at both ends are C-shaped. After multiple bridge and road casting formwork bodies 1 are spliced ​​together, they form a rectangular frame structure, and concrete can be poured on the inside for bridge and road casting construction. The splicing structure set between two adjacent road and bridge casting formwork bodies 1 includes a splicing block 21 fixed to one side surface of the road and bridge casting formwork body 1, a splicing groove 22 opened on the other side surface of the road and bridge casting formwork body 1 corresponding to the splicing block 21, and an external locking structure 23 set between the splicing block 21 and the splicing groove 22. The sealing structure set between two adjacent bridge and road casting formwork bodies 1 includes a sealing adhesive plate 31 installed on the inner side of the splice of the two bridge and road casting formwork bodies 1, and a rectangular sealing groove 33 opened on the inner surface of the bridge and road casting formwork body 1 to match the sealing adhesive plate 31.

[0017] In this embodiment, preferably, the external locking structure 23 includes multiple external screws 231 welded and fixed to the outer surface of the splicing block 21, multiple external notches 232 corresponding to the external screws 231 and opened on the outer surface of the bridge casting template body 1 and communicating with the splicing groove 22, and multiple external locking nuts 233 corresponding to the external screws 231 provided on the outer side of the bridge casting template body 1. When two adjacent bridge casting template bodies 1 are spliced, the splicing block 21 can be inserted into the splicing groove 22, so that the external screws 231 are inserted into the external notches 232, and then the two bridge casting template bodies 1 are spliced ​​together. By fitting the outer locking nut 233 onto the end of the outer screw 231 and locking it at the outer side of the splice of the two bridge and road pouring formwork bodies 1, the splicing of the two bridge and road pouring formwork bodies 1 can be quickly locked from the outer side of the splice. Since the outer notch 232 is opened on the outer side of the bridge and road pouring formwork body 1, and no holes are opened on the inner splice surface of the bridge and road pouring formwork body 1, there is no problem of grout leakage at the bolt holes when pouring concrete into the inner side of the bridge and road pouring formwork body 1. This fundamentally solves the problem of concrete seepage from the bolt holes and grout leakage during the pouring process.

[0018] In this embodiment, preferably, the width of the outer notch 232 is adapted to the diameter of the outer screw 231, and the inner end of the outer notch 232 is a semi-circle adapted to the outer screw 231, so that the outer screw 231 can be smoothly pushed into the outer notch 232 for adaptation.

[0019] In this embodiment, preferably, the two corners of the splicing block 21 are provided with inclined guide surfaces, which can facilitate the splicing block 21 to be better inserted into the splicing groove 22 during subsequent splicing, and play a guiding role.

[0020] In this embodiment, preferably, the sealing structure further includes multiple integrated T-shaped sealing strips 32 disposed on the inner surface of the sealing plate 31, and a T-shaped sealing groove 34 formed on the inner wall of the rectangular sealing groove 33 to match the T-shaped sealing strips 32. This allows the sealing plate 31 to be installed on the inner side of the joint between the two bridge and road casting template bodies 1 after the subsequent splicing is completed by the splicing structure, and the T-shaped sealing strips 32 to be inserted into the T-shaped sealing groove 34, forming multiple sealing structures on the inner side of the joint between the two bridge and road casting template bodies 1 to prevent grout leakage from the inside during the subsequent pouring process.

[0021] In this embodiment, preferably, the sealing structure further includes an integral L-shaped extension section 36 disposed at the top of the sealing adhesive sealing plate 31, a T-shaped limiting head 35 installed at the top of the outer surface of the bridge and road casting template body 1, and an installation hole 37 on the surface of the L-shaped extension section 36 for the T-shaped limiting head 35 to pass through. This allows the L-shaped extension section 36 at its top to be locked at the top of the joint of the two bridge and road casting template bodies 1 after the two bridge and road casting template bodies 1 are spliced ​​together. The end of the T-shaped limiting head 35 is locked on the outer surface of the L-shaped extension section 36 through the installation hole 37, thereby achieving stable positioning of the L-shaped extension section 36 and ensuring the installation stability of the sealing adhesive sealing plate 31 and the L-shaped extension section 36. The sealing adhesive sealing plate 31, the T-shaped sealing strip 32, and the L-shaped extension section 36 are all made of EPDM rubber, which will undergo elastic deformation when compressed.

[0022] In this embodiment, preferably, the cross-sections of both the T-shaped sealing strip 32 and the T-shaped sealing groove 34 are T-shaped.

[0023] A construction process using a concrete pouring device for building roads and bridges includes the following steps: Step 1: Construction preparation. Based on the dimensions of the road and bridge pouring section, calculate the quantity and specifications of the main body 1 of the road and bridge pouring formwork. Check the integrity and good condition of the main body 1 of the road and bridge pouring formwork, the splicing structure and the sealing structure. Clean the inner wall of the main body 1 of the road and bridge pouring formwork to ensure that the surface is free of oil stains and debris. Step 2: Template assembly. Lay out the lines in the construction area according to the design positions. First, fix the C-shaped bridge and road casting template body 1 at both ends to the preset positions. Then, use a splicing structure to assemble another bridge and road casting template body 1 on one side, so that the splicing block 21 is embedded into the splicing groove 22. Then, use the outer locking structure 23 to lock and fix it, completing the splicing of the two bridge and road casting template bodies 1. Repeat the above steps to complete the splicing of all bridge and road casting template bodies 1, forming a complete rectangular frame structure. Step 3: Splicing and sealing. Install sealant plate 31 on the inside of the splicing joint of two adjacent bridge and road casting formwork bodies 1, so that T-shaped sealant strip 32 is inserted into T-shaped sealant groove 34, and L-shaped extension section 36 is inserted at the top of the splicing joint of the two bridge and road casting formwork bodies 1, thereby forming multiple sealing measures on the inside of the splicing joint of the bridge and road casting formwork bodies 1. Step 4: Concrete pouring: After the main body of the road and bridge pouring formwork 1 has passed the acceptance inspection, concrete pouring operation is carried out on the inner side of the main body of the road and bridge pouring formwork 1. During the pouring process, the pouring speed is controlled to avoid excessive lateral pressure on the concrete, which may cause deformation of the main body of the road and bridge pouring formwork 1. Step 5: Formwork Removal: After the concrete is poured, it must be cured to more than 75% of the design strength before the main formwork 1 for the road and bridge can be removed. First, remove the sealing structure, then remove the outer locking structure 23. Disassemble the main formwork 1 for the road and bridge one by one, clean the concrete residue on the surface of the main formwork 1, and check the integrity of the splicing structure and sealing structure for reuse.
