Description

Technical Field

[0001] This utility model relates to the field of bridge protection technology, specifically to a horizontal casting mold for bridge guardrails. Background Technology

[0002] Bridge and road guardrails are safety facilities installed on both sides of a bridge or road in the width direction. They are an important component of the bridge or road structure, and their main purpose is to increase the durability and safety of the bridge or road. Bridge and road guardrails are generally thin plate structures supplemented by crossbeams and columns to ensure that the thin plate structure has sufficient structural support performance and impact resistance and compressive strength.

[0003] Bridge and road guardrails are generally prepared by casting. To ensure the structural performance of the bridge and road guardrails, the connection performance between the guardrails, beams and columns is an important consideration. To improve the connection performance between the three, on the one hand, it is necessary to pre-embed steel bars and other connectors at the connection to indirectly improve the structural performance of the connection. On the other hand, it is necessary to consider casting as a whole as possible, so that the beams, columns and guardrails are as a whole as possible during casting, thereby improving the connection performance.

[0004] When pouring the protective plate, horizontal molds and vertical molds can be used. The advantage of horizontal molds is that the gravitational potential energy of concrete is lower during the pouring process, which will not put too much pressure on the mold and has lower requirements for the structural performance of the mold.

[0005] Existing horizontal molds are generally complex to assemble, require a lot of fixing work, and have low efficiency in both assembly before pouring and demolding after pouring, making them inconvenient to reuse.

[0006] Therefore, this application is hereby submitted. Utility Model Content

[0011] In another preferred embodiment, the beam mold includes a supporting beam mold and a through beam mold; the supporting beam mold is connected to one end of the column mold to form a T-shaped structure, and the supporting beam mold is used to cast the supporting beam; the through beam mold is connected to the middle of the column mold to form a cross-shaped structure, and the through beam mold is used to cast the through beam.

[0012] In another preferred embodiment, the column formwork includes a pair of parallel first templates and a second template, the second template being perpendicular to and connected to the first templates to form a U-shaped second casting groove; both the first templates and the second template are perpendicular to the cover plate; the side of the second casting groove away from the second template is connected to the support beam formwork; the two first templates are collinearly perforated, and the beam-through formwork is detachably inserted into the perforation.

[0013] In another preferred embodiment, the supporting beam mold includes a pair of parallel third templates and a pair of parallel fourth templates. The third templates are perpendicularly arranged and connected to the fourth templates to form a rectangular frame-shaped third casting groove. One of the third templates has several through holes, which correspond one-to-one with the column mold. The side of the second casting groove away from the second template is connected to the corresponding through hole, so that the second casting groove is connected to the third casting groove.

[0014] In another preferred embodiment, the first template, the second template, the third template, and the fourth template all have the same height.

[0015] In another preferred embodiment, the through-beam formwork includes a pair of parallel fifth templates, a pair of parallel sixth templates, and a seventh template. The sixth template is perpendicular to and connected to the fifth template to form a fourth pouring groove. The seventh template covers the top of the fourth pouring groove to close the top of the fourth pouring groove. The fifth template and the sixth template have the same height, but the height is much smaller than that of the first template.

[0016] In another preferred embodiment, there are two column molds; the beam mold is divided into two insertion sections and one fixed section; the fixed section is fixedly connected to the cover plate, and the insertion section is detachably inserted into the cover plate; the column mold is sandwiched between the fixed section and one of the insertion sections, so that the insertion section, the column mold and the fixed section are connected in sequence.

[0034] Example

[0035] Please refer to Figures 1 to 11 As shown, this embodiment provides a horizontal casting mold for bridge guardrails, including: a plate mold 10, the top surface of which is set as a horizontal plane, and a first casting groove 11 is excavated downward on the top surface of the plate mold 10 for casting the guardrail 1; a second mold including multiple cover plates 20, the cover plates 20 being horizontally placed over the opening of the first casting groove 11, the cover plates 20 being detachably connected to the plate mold 10, and a transverse groove 21 or a longitudinal groove 22 being reserved between two adjacent cover plates 20; and a third mold including multiple beam molds 3. 0. The beam mold 30 corresponds one-to-one with the transverse slot 21 and is detachably connected to the cover plate 20, so that the corresponding transverse slot 21 is closed while the beam mold 30 is connected to the first casting groove 11. The beam mold 30 is used to cast the transverse beam. The fourth includes a plurality of column molds 40, the column mold 40 corresponds one-to-one with the longitudinal slot 22 and is detachably connected to the cover plate 20, so that the corresponding longitudinal slot 22 is closed while the column mold 40 is connected to the first casting groove 11. The column mold 40 is used to cast the column 2.

[0036] The horizontal casting mold for bridge guardrails disclosed in this embodiment comprises a plate mold 10, a cover plate 20, a beam mold 30, and a column mold 40. Horizontal slots 21 and longitudinal slots 22 are pre-reserved between adjacent cover plates 20, allowing the beam mold 30 or column mold 40 to be detachably connected to the cover plate 20. A first casting groove 11 is formed on the top of the plate mold 10. In use, the guardrail 1 is horizontally cast in the first casting groove 11. After the guardrail 1 has initially set, the beam mold 30 and column mold 40 are connected to the cover plate 20, and horizontal beams and vertical beams are cast in the beam mold 30 and column mold 40 respectively. The column 2 connects the two to the initially solidified protective plate 1 to effectively improve structural performance. After complete solidification, the beam mold 30 and column mold 40 are removed, and then the cover plate 20 is removed, so that the solidified protective plate 1 with the crossbeam and column 2 can be lifted out from the first pouring groove 11. Through the cooperation of the above features, the horizontal pouring mold of the bridge protective plate can effectively solve the problems that the horizontal mold structure is relatively complex, requires a lot of fixing work, and has low efficiency in assembly before pouring and demolding after pouring, and is not convenient for reuse.

[0037] To provide a specific explanation of the detachable connection structure between the beam mold 30 and the column mold 40 and the cover plate 20, the bottom surface of the edge of the cover plate 20 has a slot 201; the bottom edges of the beam mold 30 and the column mold 40 are both provided with protruding edges 202, the thickness of the protruding edges 202 matching the groove depth of the slot 201; the beam mold 30 or the column mold 40 is detachably slidably inserted into the slot 201 through the protruding edges 202.

[0038] To further explain the specific structure of the beam mold 30, the beam mold 30 includes a supporting beam mold 31 and a through beam mold 32; the supporting beam mold 31 is connected to one end of the column mold 40 to form a T-shaped structure, and the supporting beam mold 31 is used to cast the supporting beam 3; the through beam mold 32 is connected to the middle of the column mold 40 to form a cross-shaped structure, and the through beam mold 32 is used to cast the through beam 4.

[0039] To provide a specific explanation of the structure of the column mold 40, the column mold 40 includes a pair of parallel first templates 41 and a second template 42. The second template 42 is perpendicular to and connected to the first template 41 to form a U-shaped second casting groove 43. Both the first template 41 and the second template 42 are perpendicular to the cover plate 20. The side of the second casting groove 43 away from the second template 42 is connected to the support beam mold 31. The two first templates 41 have collinear through holes 411, and the through beam mold 32 can be detachably inserted into the through holes 411.

[0040] With the above settings, the column mold 40 can be connected to the first casting groove 11, so that the column 2 can be cast as a whole with the protective plate 1; by setting the through hole 411, during casting, the through beam 4 can be cast first through the through beam mold 32, and then the column 2 can be cast through the column mold 40, so that the column 2 and the through beam 4 can be cast as a whole.

[0041] To provide a specific explanation of the structure of the supporting beam mold 31, the supporting beam mold 31 includes a pair of parallel third templates 311 and a pair of parallel fourth templates 312. The third templates 311 and the fourth templates 312 are perpendicularly arranged and connected to form a rectangular frame-shaped third casting groove 313. Each of the third templates 311 has several through holes 3111, and each through hole 3111 corresponds to a column mold 40. The side of the second casting groove 43 away from the second template 42 is connected to the corresponding through hole 3111, so that the second casting groove 43 is connected to the third casting groove 313.

[0042] The above settings connect the support beam mold 31 to the first casting groove 11, and also connect the third casting groove 313 to the first casting groove 11.

[0043] Preferably, the first template 41, the second template 42, the third template 311, and the fourth template 312 all have the same height.

[0044] To provide a specific explanation of the structure of the through-beam formwork 32, the through-beam formwork 32 includes a pair of parallel fifth templates 321, a pair of parallel sixth templates 322, and a seventh template 323. The sixth template 322 is perpendicularly arranged and connected to the fifth template 321 to form a fourth casting groove 324. The seventh template 323 covers the top of the fourth casting groove 324 to close the top of the fourth casting groove 324. The fifth template 321 and the sixth template 322 have the same height, and are much smaller than the height of the first template 41.

[0045] With the above settings, the beam mold 32 can be connected to the column mold 40, and the height direction of the beam mold 32 is closed, so that the beam 4 can be poured at the same time during the pouring of the column 2, thereby making the beam 4 and the column 2 cast as one.

[0046] To further explain the specific structure of the column mold 40 and the beam mold 32, there are two column molds 40; the beam mold 32 is divided into two insertion sections and one fixed section; the fixed section is fixedly connected to the cover plate 20, and the insertion section is detachably inserted into the cover plate 20; the column mold 40 is sandwiched between the fixed section and one insertion section, so that the insertion section, the column mold 40 and the fixed section are connected in sequence.

[0047] In order to improve the connection performance between the cover plate 20 and the plate mold 10, the beam mold 30 and the column mold 40 are connected with vertically arranged limiting plates 50. When the beam mold 30 or the column mold 40 is connected to the cover plate 20, the limiting plate 50 is attached to the side wall of the plate mold 10.

[0048] It should be noted that the limiting plate 50 can be detachably connected to the plate mold 10 via bolts.

[0049] To further improve the connection and structural performance between the cover plates 20, several cover plates 20 are fixedly connected by a connecting bridge 60; the connecting bridge 60 is provided with a bridge arch 61 that matches the height of the beam mold 30 or the column mold 40.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
