Description

Technical Field

[0001] The utility model relates to the technical field of curbstone processing, and particularly relates to a forming mold for a luminous curbstone. Background Art

[0002] A curbstone is a marker stone set between a road surface and other structures. Curbstones are usually required between the median strip and the road surface of urban roads, and between the sidewalk and the road surface. For example, a Chinese patent with the authorization announcement number CN218621926U and the authorization announcement date of March 14, 2023 discloses "A Luminous Curbstone". After the lamp slot is lit, the light can pass through the transparent lamp tube and the light-transmitting slot.

[0003] At the same time, the processing of curbstones involves the design of forming molds. For example, a Chinese patent with the authorization announcement number CN219820062U and the authorization announcement date of October 13, 2023 discloses "A Forming Mold for a Luminous Curbstone", which includes a main template, side templates, and an air inflation assembly. Among them, after the air inflation assembly is inflated, it fills the space corresponding to the through holes of the two side templates and passes through the through holes at both ends to form the weight reduction holes of the curbstone.

[0004] However, in the above comparative patents, when forming the weight reduction holes of the curbstone through the air inflation assembly, since the air inflation assembly expands after being inflated, during the process of filling concrete into the forming mold, the middle part of the air inflation assembly is prone to bending when受力, resulting in irregular shapes of the weight reduction holes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a forming mold for a luminous curbstone, which has the function of improving the forming quality of the weight reduction holes of the curbstone.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A forming mold for a luminous curbstone includes a main template with a cross-section in a "U" shape, and two side templates detachably arranged on both sides of the main template. The main template is provided with a first protrusion for placing the lamp tube of the luminous curbstone and corresponding to the light-transmitting slot. The side template is provided with a second protrusion corresponding to the installation slot of the luminous curbstone. The side template is provided with a third protrusion for installing the connecting sleeve of the luminous curbstone. A weight reduction hole forming assembly corresponding to the weight reduction holes of the luminous curbstone is arranged between the two side templates. The side template is provided with a connecting hole. The weight reduction hole forming assembly includes two inner cores with one end respectively installed at the connecting holes of the two side templates, and a metal connecting piece arranged between the ends of the two inner cores close to each other. The two end faces of the metal connecting piece are provided with limiting parts embedded in the inner cores, and the inner cores are provided with through holes extending to the limiting parts.

[0007] By adopting the above technical scheme, in the process of forming the luminous curbstone, since the weight-reducing hole forming component is made of hard material, deformation during concrete pouring can be avoided, thereby ensuring the forming quality of the weight-reducing hole; and when demolding, after removing the side formwork, an iron rod or other tool is first inserted into the through hole of one of the inner cores and abuts against the limiting part of the metal connector, and the end of the tool of the iron rod is hit by external force, so that the other inner core is demolded by a lateral force. The demolding work of the entire weight-reducing hole forming component can be realized by this principle.

[0008] The utility model is further configured as follows: the inner core comprises two shells which are symmetrically arranged and detachably connected, a reinforcement structure is arranged inside the shells, and the through hole is formed in the middle of the connection between the two shells.

[0009] By adopting the above technical solution, the inner core includes two symmetrically arranged and detachably connected shells, and a reinforcement structure is arranged inside the shells, so that the weight of the inner core can be reduced while ensuring the structural strength of the inner core.

[0010] The utility model is further configured as follows: the reinforcement structure comprises a plurality of first reinforcement plates vertically arranged in the shell and arranged along the length direction thereof, and a second reinforcement plate horizontally arranged in the shell and connected to the plurality of first reinforcement plates.

[0011] By adopting the above technical solution, the reinforcement structure includes a plurality of first reinforcement plates vertically arranged in the shell and arranged along its length direction, and a second reinforcement plate horizontally arranged in the shell and connected to the plurality of first reinforcement plates, thereby ensuring the structural strength of the shell.

[0012] The utility model is further configured as follows: an embedding groove extending along the length direction of the first protrusion is provided on the first protrusion, and a rubber strip is provided in the embedding groove for pressing against the peripheral side of the lamp tube of the luminous curbstone and corresponding to the light-transmitting groove.

[0013] By adopting the above technical solution, in the process of forming the luminous curbstone, concrete will penetrate into the gap between the first protrusion and the lamp tube, resulting in the need to clean up the part of the light-transmitting groove corresponding to the formed lamp tube where concrete has solidified. At this time, a rubber strip is provided to press against the surrounding side of the light-transmitting groove corresponding to the lamp tube, thereby preventing concrete from penetrating into the gap between the first protrusion and the lamp tube. In addition, the part of the rubber strip attached to the corresponding light-transmitting groove after forming can be directly pried open at one end of the rubber strip using a screwdriver or other tool and then pulled out.

[0014] The utility model is further configured as follows: the rubber strip includes a strip portion embedded in the embedding groove and an arc portion arranged on the strip portion, and hollow portions with circular cross-sections and used to press against the circumference of the lamp tube of the luminous curb are arranged on both sides of the arc portion, and the length of the arc portion is the same as the length of the first protrusion.

[0015] By adopting the above technical solution, the cross-section of the hollow part is circular ring-shaped, which can improve its deformation ability, thereby further ensuring the sealing performance when it abuts against the circumferential side of the lamp tube of the luminous curbstone. In addition, although there will be a slight gap between the end of the rubber strip and the lamp tube at this time, only a very small amount of concrete will penetrate during actual production. When using tools such as a screwdriver to directly pry open the rubber strip, this part of the penetrated concrete can be pried open by the way. Description of the Drawings

Detailed Description of the Invention

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Embodiment: A forming mold for a luminous curbstone, as Figures 1 to 3 shown, includes a main template 1 with a "U"-shaped cross-section, and two side templates 2 detachably arranged on both sides of the main template 1. The main template 1 is provided with a first protruding part 11 for placing the lamp tube of the luminous curbstone and corresponding to the light-transmitting groove, and the side template 2 is provided with a second protruding part 21 corresponding to the installation groove of the luminous curbstone, and the side template 2 is provided with a third protruding part 22 for installing the connecting sleeve of the luminous curbstone.

[0024] As Figure 3 and Figure 4As shown, the first protrusion 11 is provided with an embedding groove 12 extending along the length direction thereof, and a rubber strip 4 is provided in the embedding groove 12 for pressing against the peripheral side of the lamp tube of the luminous curbstone and corresponding to the light-transmitting groove. The rubber strip 4 includes a strip portion 41 embedded in the embedding groove 12, an arc portion 42 provided on the strip portion 41, and hollow portions 43 with circular cross-sections and for pressing against the peripheral side of the lamp tube of the luminous curbstone are provided on both sides of the arc portion 42, and the length of the arc portion 42 is the same as that of the first protrusion 11.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, a weight-reducing hole forming assembly 3 having weight-reducing holes corresponding to the luminous curbstones is provided between the two side templates 2, a connecting hole 23 is provided on the side template 2, and the weight-reducing hole forming assembly 3 includes two inner cores 31 whose one ends are respectively installed at the connecting holes 23 of the two side templates 2, and a metal connector 35 provided between the ends of the two inner cores 31 close to each other, and limiting portions 351 embedded in the inner core 31 are provided on both end surfaces of the metal connector 35, and a through hole 32 extending to the limiting portion 351 is provided on the inner core 31.

[0026] like Figure 3 and Figure 5 As shown, the inner core 31 includes two symmetrically arranged and detachably connected shells 33. The two shells 33 are connected by a plug-in column and a plug-in slot, and a reinforcing structure 34 is arranged in the shell 33, and a through hole 32 is formed in the middle of the connection between the two shells 33. The reinforcing structure 34 includes a plurality of first reinforcing plates vertically arranged in the shell 33 and arranged along the length direction thereof, and a second reinforcing plate horizontally arranged in the shell 33 and connected to the plurality of first reinforcing plates.

[0027] Implementation effect: In the process of forming the luminous curbstone, since the weight-reducing hole forming component 3 is made of hard material, deformation can be avoided when concrete is poured, thereby ensuring the forming quality of the weight-reducing hole; and when demolding, after removing the side formwork 2, an iron rod or other tool is first passed through the through hole 32 of one of the inner cores 31 and abuts against the limiting portion 351 of the metal connector 35, and the end of the tool of the iron rod is hit by external force, so that the other inner core 31 is subjected to a lateral force for demolding. The demolding work of the entire weight-reducing hole forming component 3 can be realized through this principle.

[0028] The inner core 31 includes two symmetrically arranged and detachably connected shells 33, and a reinforcing structure 34 is arranged in the shell 33, so as to reduce the weight of the inner core 31 while ensuring the structural strength of the inner core 31. The reinforcing structure 34 includes a plurality of first reinforcing plates vertically arranged in the shell 33 and arranged along the length direction thereof, and a second reinforcing plate horizontally arranged in the shell 33 and connected to the plurality of first reinforcing plates, so as to ensure the structural strength of the shell 33.

[0029] In the process of forming the luminous curbstone, concrete will penetrate into the gap between the first protrusion 11 and the lamp tube, resulting in the solidified concrete in the part of the light-transmitting groove corresponding to the formed lamp tube, which needs to be cleaned. At this time, a rubber strip 4 is set to press against the peripheral side of the light-transmitting groove corresponding to the lamp tube, so as to prevent the concrete from penetrating into the gap between the first protrusion 11 and the lamp tube. In addition, the part of the rubber strip 4 attached to the corresponding light-transmitting groove after forming can be directly pried open by a screwdriver or other tool and then pulled off. The cross-section of the hollow part 43 is circular, which can improve its deformation ability, thereby further ensuring the sealing when it is pressed against the peripheral side of the lamp tube of the luminous curbstone; in addition, although there is a slight gap between the end of the rubber strip 4 and the lamp tube at this time, only a small amount of concrete will penetrate in actual production. When the rubber strip 4 is directly pried open by a screwdriver or other tool, this part of the infiltrated concrete can be pried open at the same time.
