Description

Technical Field

[0001] The present application relates to the technical field of building construction, and particularly relates to a formwork for a crash barrier on a mountainous expressway. Background Art

[0002] A crash barrier is a wall part used on both sides of roads and railways in civil engineering, and is mostly used on both sides of high embankment subgrade projects, bridge projects, and subgrade projects with small radius and large superelevation. A crash barrier is a safety facility, which is cast with reinforced concrete, and its structure protrudes towards the driving direction, which can play a good buffering role for the impact force of vehicles, play the role of anti-collision and isolation, ensure traffic safety, and at the same time play the role of guiding the line of sight and beautifying the environment.

[0003] Chinese Patent with the patent number CN103255716A discloses a formwork for a crash barrier, including an outer formwork and an inner formwork matching with the outer formwork. The inner formwork and the outer formwork are fixed by tie rods. A bending plate and an upper top plate are sequentially connected to the bottom of the outer formwork, and the bending plate and the upper top plate form a hook shape. When the tie rod transmits the tension force to the outer formwork in the present invention, the outer formwork forms a rotating shaft, and the center of the rotating shaft is the contact point between the upper top plate and the bottom of the bridge. Taking this point as the center, the tension force of the tie rod makes the outer formwork form a rotational moment. In this way, the position of the outer formwork can be fixed, and the acting force between its bottom and the bridge is increased, avoiding problems such as formwork explosion caused by concrete vibration during the concrete pouring process; compared with the traditional form of fixing the inner formwork and the outer formwork with scaffolding, by changing the structure of the outer formwork, the use of scaffolding is avoided, the erection time and erection cost of the scaffolding are reduced, and the construction cost is greatly reduced.

[0004] However, the inventor found during the conception and implementation of the above application that in the actual use process of the above technical solution, its disassembly and assembly are inconvenient, resulting in a slow disassembly and assembly speed. Utility Model Content

[0037] Inner formwork 1;

[0038] Outer formwork 2 with a lower part protruding outward;

[0039] Wherein, a lower pull rod 3 is penetrated through the lower parts of the inner formwork 1 and the outer formwork 2, and the upper ends of the two are bent to form an arc edge 4. A first channel steel 5 is fixed on the outer side of the arc edge 4. An upper pull rod 6 is penetrated between two groups of the first channel steels 5. The upper and lower ends of the inner formwork 1 and the outer formwork 2 are connected by the upper pull rod 6 and the lower pull rod 3.

[0040] Specifically, the inner formwork 1 and the outer formwork 2 form inner and outer formworks, and concrete is poured into the gap between the two. The upper ends of the inner formwork 1 and the outer formwork 2 are bent towards each other to form an arc edge 4. By setting the arc edge 4, it is convenient to remove the inner and outer formworks, and at the same time reduce the damage to the formed concrete of the crash barrier; after the lower pull rod 3 and the upper pull rod 6 are penetrated through the upper and lower ends of the inner formwork 1 and the outer formwork 2, they are locked by a nut gasket 16 and a nut 17, so that the inner formwork 1 and the outer formwork 2 are connected and fixed; the first channel steel 5 is fixedly welded to the outer side of the arc edge 4, and the first channel steel 5 is used for installing the upper pull rod 6;

[0041] Compared with the traditional crash barrier formwork, for this crash barrier formwork, only the lower pull rod 3 and the upper pull rod 6 need to be inserted into the upper and lower ends of the inner formwork 1 and the outer formwork 2, and then the two are locked, so as to realize the connection and fixation of the inner formwork 1 and the outer formwork 2, thereby realizing the installation of the crash barrier formwork. When disassembling the crash barrier formwork, only need to loosen the nut and remove the upper pull rod 6 and the lower pull rod 3, then the disassembly of the crash barrier formwork can be realized.

[0045] Specifically, the standard length of the inner and outer formwork composed of the inner formwork 1 and the outer formwork 2 is 2m, and the non-standard lengths are 1.5m and 1m. They are combined according to the turning radius and superelevation of the mountain expressway, that is, the method of fitting the curve with short straight lines is adopted to control the anti-collision wall line type;

[0046] During combination, several inner formworks 1 are quickly connected at the bottom through male corner fasteners 7 and female corner fasteners 8, and several outer formworks 2 are quickly connected at the bottom through male corner fasteners 7 and female corner fasteners 8. By setting the male and female fasteners, the formwork erection speed is increased and the construction safety risk is reduced.

By setting the angle steels 11 and the reinforcing plates 12, the structural strength of the inner formwork 1 and the outer formwork 2 is enhanced.

[0055] Optionally, a second channel steel 13 is provided at the lower part of the outer walls of the inner formwork 1 and the outer formwork 2, and the lower pull rod 3 is arranged between two groups of the second channel steels 13.

[0057] Optionally, the anti-collision wall formwork for mountain expressways further includes an end formwork 14 and a crack-sealing formwork 15 with an arc-shaped bottom.

[0058] Specifically, the crack-sealing formwork 15 is a partition board used to prevent concrete from pouring into the crack during wall pouring. The crack-sealing formwork 15 is generally located between two adjacent formworks, and the space formed between two opposite formworks is filled with concrete to form a wall. The crack-sealing formwork 15 is provided with screw holes, and the crack-sealing formwork 15 can be connected to the inner formwork 1 and the outer formwork 2 through bolts. The bottom of the crack-sealing formwork 15 is set to be arc-shaped, which is beneficial to the removal of the crack-sealing formwork 15.

[0059] Two end formworks 14 with a thickness of 0.5 cm and a crack-sealing formwork 15 with a thickness of 1 cm are arranged at the crack to form a wide crack, which is beneficial to the adjustment of the anti-collision wall line type, reduces construction deformation and deviation, and beautifies the forming effect.

[0060] The structures of the end formwork 14 and the crack-sealing formwork 15 are similar to those of the inner formwork 1 and the outer formwork 2, and will not be further described here.
