Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically relating to a wellhead mold for municipal engineering. Background Technology

[0002] Municipal engineering projects include: road and traffic engineering, underground pipeline engineering, river and lake system engineering, and overhead power line engineering. The construction of municipal engineering projects involves many water supply pipelines, drainage pipelines, power line pipelines, and telecommunication line pipelines, all of which require the provision of inspection wells.

[0003] Most manholes are prefabricated components, assembled or installed on-site. However, the manhole opening location requires on-site construction using cement or asphalt, which is a significant factor affecting construction progress. Currently, there is a lack of a dedicated mold for manhole opening location to improve construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a wellhead mold for municipal engineering, which can effectively improve the construction efficiency of wellhead locations.

[0005] The technical solution is as follows:

The first mold body includes: a first arc panel, a first arc frame, a first side frame, and hooks. Two first arc frames are connected to the upper and lower sides of the inner wall of the first arc panel, respectively. Two first side frames are connected to the left and right sides of the inner wall of the first arc panel, respectively. The two ends of the first side frames are connected to the two first arc frames. The hook ends are connected to the inner wall of the first arc panel and are located inside the first side frame. The first side frame has a through hole. The second mold body includes: a second arc panel, a second arc frame ... The first mold assembly consists of a first mold assembly, a second frame, and two second arc-shaped frames connected to the upper and lower sides of the inner wall of the second arc panel, respectively. The two second frame sides are connected to the left and right sides of the inner wall of the second arc panel, respectively. Each end of the second frame side is connected to one of the two second arc-shaped frames. The second frame side has through holes. Connecting bolts pass through the through holes of the first and second frame sides, connecting the second frame sides of the left and right sides of the second mold assembly to the first frame sides of the two first mold assemblies. Connecting bolts also pass through the through holes of the first frame sides of the two first mold assemblies, connecting the first frame sides of the two first mold assemblies. Tightening bolts are connected at both ends to hooks on the two first mold assemblies.

[0007] Furthermore, the left and right sides of the second mold segment are respectively connected to one side of the two first mold segments, and the other side of the two first mold segments are connected to each other.

[0008] Furthermore, the through holes in the first and second borders are positioned relative to each other.

[0009] Furthermore, a limiting folding plate is connected to the inner wall of the first arc panel. The limiting folding plate is L-shaped, with one end connected to the inner wall of the first arc panel and the other end extending to the outer side of the first frame.

[0010] Furthermore, angle steel is used for the first frame, the second frame, and the limiting folding plate.

[0011] Furthermore, the inner wall of the first arc panel is connected with reinforcing ribs, with the two ends of the reinforcing ribs connected to the left and right sides of the inner wall of the first arc panel, respectively.

[0012] Furthermore, the tensioning bolt includes: a double-ended nut and a screw hook. The double-ended nut has threaded holes at both ends, and the threads of the two threaded holes are in opposite directions. The screw hook has external threads on the outer wall of the screw section and a hook at the end. The screw section is connected to the threaded hole.

[0013] This utility model has the following advantages compared with the prior art:

[0014] After this utility model is installed on site, concrete can be poured directly on the outside of the wellhead, or asphalt can be filled, without the need for on-site formwork, which can effectively improve the construction efficiency of the wellhead.

[0015] This utility model is easy and quick to assemble and disassemble, and has high support strength. Attached Figure Description

[0024] The first mold component 1 includes: a first arc panel 11, a first arc frame 12, a first side frame 13, and a hook 14. Two first arc frames 12 are respectively connected to the upper and lower sides of the inner wall of the first arc panel 11, and two first side frames 13 are respectively connected to the left and right sides of the inner wall of the first arc panel 11. The two ends of each first side frame 13 are connected to the two first arc frames 12. The hook 14 is located on the inner wall of the first arc panel 11 and is situated inside the first side frame 13. The two ends of a tension bolt 3 are respectively connected to the hooks 14 of the two first mold components 1.

[0025] To facilitate assembly, a limiting folding plate 15 is added. The limiting folding plate is L-shaped, with one end connected to the inner wall of the first arc panel 11 and the other end extending to the outside of the first frame 13.

[0026] In order to improve the structural strength of the first mold body 1, the inner wall of the first arc panel 11 is connected with a reinforcing rib 16, and the two ends of the reinforcing rib 16 are respectively connected to the left and right sides of the inner wall of the first arc panel 11.

[0027] like Figure 3 The diagram shown is a structural schematic of the second mold component 2 in this utility model.

[0028] The second mold component 2 includes: a second arc panel 21, a second arc frame 22, and a second side frame 23. The two second arc frames 22 are respectively connected to the upper and lower sides of the inner wall of the second arc panel 21, and the two second side frames 23 are respectively connected to the left and right sides of the inner wall of the second arc panel 21. The two ends of the second side frame 23 are respectively connected to the two second arc frames 22.

[0029] The first frame 13, the limiting folding plate 15, and the second frame 23 are made of angle steel.

[0030] To improve the connection strength between the two first mold parts 1 and the second mold part 2, the first frame 13 is provided with a first frame through hole 17, and the second frame 23 is provided with a second frame through hole 24. After the two first mold parts 1 and the second mold part 2 are combined, the first frame through holes 17 and 24 are positioned opposite each other. Connecting bolts 4 are inserted into the first frame through holes 17 and 24 to connect the first mold parts 1 and the second mold part 2. The connecting bolts 4 are inserted into the first frame through holes 17 of the two first mold parts 1 to connect the first frames of the two first mold parts.

The screw hook 32 has external threads on the outer wall of the screw section and a hook 33 at the end. The screw section is connected to the threaded hole. The threads of the two threaded holes are in opposite directions. When the double-ended nut 31 is rotated, the two screw hooks 32 move in opposite directions.

[0033] When assembling the manhole mold for municipal engineering, the first mold part 1 and the second mold part 2 are placed on the top of the manhole opening of the inspection well, and the two first mold parts 1 are placed on both sides of the second mold part 2. After closing, the two second arc-shaped frames 22 of the second mold part 2 respectively abut against the limiting folding plate 15. The hooks 33 at both ends of the tension bolt 3 are hooked onto the pull hooks 14 of the two first mold parts 1 respectively. The connecting bolt 4 is inserted into the through hole 17 of the first frame and the through hole 24 of the second frame, and the first mold part 1 and the second mold part 2 are assembled.
