The crash barriers made by on-site casting have the advantages of good integrity, few construction gaps, and good durability.

[0003] However, the guardrail construction template in the prior art still has the following shortcomings:

[0004] 1. Most of them are tension bolt type, which requires repeated installation and removal of tension bolts. After the template is removed, the holes at the tension screws on the anti-collision guardrail need to be specially repaired and repainted, which slows down the construction speed. If the blocking is not ideal, it also increases certain safety hazards;

[0005] 2. The construction surface of the outer template of the anti-collision guardrail is suspended, which makes it difficult to control and is not conducive to adjusting its angle;

[0006] 3. Insufficient stability, the formwork is prone to deformation when subjected to pressure from internal concrete. Utility Model Content

[0031] See also Figure 1 , Figure 2 A guardrail construction template provided in this embodiment can be used for the molding and production of anti-collision guardrails at the edge of the road. It includes an inner template component 4 and an outer template component 7 connected to the inner template component 4 through a connecting arm 5, wherein the outer template component 7 and the inner template component 4 are spaced and arranged opposite to each other, and a cavity is formed between the two. After the construction workers pour concrete into it, it is cast and formed into the guardrail.

[0032] The connecting arm 5 connecting the inner formwork assembly 4 and the outer formwork assembly 7 can be arranged on the top of the two formwork assemblies, and should avoid interfering with the guardrail construction, thereby avoiding leaving holes on the guardrail and eliminating the need for subsequent hole repairing procedures. As an alternative, it can also be arranged on the side of the two formwork assemblies, and any installation position that can achieve the connection of the two formwork assemblies and does not interfere with the guardrail construction is allowed.

[0033] The inner formwork assembly 4 is connected to a plurality of support assemblies on one side away from the outer formwork assembly 7. During construction, the support assemblies can be connected to the construction object or surrounding fixtures to support and fix the inner formwork assembly 4. The construction object here refers to the construction object that needs to be constructed with guardrails, and the surrounding fixtures can be the ground or other fixed buildings. The specific connection position of the support assembly can be selected according to the on-site construction environment. Figure 1 For example, when casting guardrails for bridges, the support assembly can be fixed on the bridge flange plate 1. When casting guardrails on both sides of the road, the support assembly can be connected to the road edge pavement layer.

[0034] In this embodiment, an adjustment and positioning assembly is also provided on the outer formwork assembly 7, which is used to adjust and position the installation angle of the outer formwork assembly 7, so as to ensure the verticality between the guardrail and the construction object. The adjustment and positioning assembly can be connected to the bottom of the outer formwork assembly 7. During construction, the adjustment and positioning assembly can abut against the construction object or surrounding fixed objects. At this time, the connecting arm 5 and the adjustment and positioning assembly can cooperate with each other to achieve relative fixation of the outer formwork assembly 7 and the inner formwork assembly 4.

[0035] See also Figure 3 , Figure 4 As an embodiment of the present application, the adjustment and positioning assembly may include an adjustment plate 9 and an adjustment bolt 10. The adjustment plate 9 is provided with an adjustment hole 9011. The adjustment bolt 10 passes through the adjustment hole 9011 and is connected to the outer template assembly 7. The adjustment hole 9011 may be set as a strip hole or as a plurality of through holes arranged at intervals.

[0036] Continue to see Figure 1 Taking the construction object as a bridge as an example, during construction, the adjustment plate 9 can be placed against the lower side of the bridge flange plate 1. When the adjustment bolt 10 is inserted into the strip hole at different positions or the selected through hole is different, the installation angle of the corresponding outer template assembly 7 is also different. At this time, the cavity for guardrail molding can be regarded as being surrounded by the outer template assembly 7, the inner template assembly 4, the adjustment and positioning assembly and the bridge flange plate 1.

[0037] It should be noted that after the inner formwork assembly 4 is positioned and fixed by the support assembly, in order to achieve an adjustable installation angle of the outer formwork assembly 7, the connecting arm 5 and the outer formwork assembly 7 can be set to be movably connected, specifically, by a rotating pin 6 or other hinged assembly.

[0038] When installing the outer formwork assembly 7, the installation trolley can be used to lift the outer formwork assembly 7 and hang it in place. The construction workers stand on the construction platform outside the construction object and connect the outer formwork assembly 7 and the inner formwork assembly 4 through the connecting arm 5. Then, the outer formwork assembly 7 is adjusted to a suitable installation angle by adjusting the positioning assembly, and the adjustment plate 9 and the outer formwork assembly 7 are locked and fixed with the adjusting bolts 10, thereby realizing the installation and positioning of the outer formwork assembly 7.

[0039] The guardrail construction template provided in this embodiment does not require tension bolts between the outer template component 7 and the inner template component 4 to achieve the fixation of the two template components. There is no construction interference between the two template components and the guardrail, which avoids leaving holes on the guardrail, eliminates the need for subsequent hole repairing procedures, and improves the efficiency and safety of guardrail construction. The installation angle of the outer template component 7 can be adjusted by adjusting the positioning component, which can ensure that a good verticality is maintained between the guardrail and the construction object. Example 2

[0040] See also Figures 1 to 4This embodiment further refines and improves the technical solution based on Embodiment 1.

In this embodiment, in order to prevent the connecting arm 5 from interfering with the cavity used for guardrail molding, the first outer guardrail plate 403 may be set higher than the first inner guardrail plate 402, and the second outer guardrail plate 703 may be set higher than the second inner guardrail plate 702, and one end of the connecting arm 5 is connected to the first outer guardrail plate 403 of the inner template assembly 4 through a rotating pin 6, and the other end is also connected to the second outer guardrail plate 703 of the outer template assembly 7 through a rotating pin 6.

[0042] In actual construction sites, it is usually necessary to install multiple guardrail construction templates provided by this embodiment into a multi-section structure for common use to form multiple continuous guardrails. In order to facilitate installation and connection, and the connecting arms 5 between multiple guardrail construction templates can work without interfering with each other, the first inner guardrail plate 402 and the second inner guardrail plate 702 are respectively protruding from the first outer guardrail plate 403 and the second outer guardrail plate 703 in the front-to-back direction, and multiple guardrail construction templates can be assembled through the protruding first outer guardrail plate 403 and the second outer guardrail plate 703. The first inner guardrail plate 402 and the second inner guardrail plate 702 are both provided with a plurality of bolt holes, and the bolts passing through the bolt holes are used to realize the fastening between the first inner guardrail plates 402 of the two adjacent guardrail construction templates, and the fastening between the second inner guardrail plates 702 of the two adjacent guardrail construction templates.

[0043] In order to further improve the stability of the suspended outer formwork assembly 7, the present application sets the adjustment plate 9 as a bending structure to increase the contact area between the adjustment plate 9 and the construction object or surrounding fixed objects. Figure 3 , Figure 4 The adjustment plate 9 includes an adjustment portion 901 and a support portion 902 connected to the adjustment portion 901. The adjustment hole 9011 is provided on the adjustment portion 901. The support portion 902 is in a planar shape. During construction, the support portion 902 can be pressed against the lower side of the construction object or surrounding fixed objects. Taking a bridge as an example, the support portion 902 can be pressed against the lower side of the bridge flange plate 1 to adjust the line contact between the adjustment plate 9 and the lower side of the bridge flange plate 1 to a more stable surface contact. Among them, the support portion 902 can be formed by bending the adjustment portion 901 inward at a certain angle.

[0044] See also Figure 1 The support assembly provided in this embodiment can be set to two, each support assembly includes a support seat 2 and at least two support rods 3, the two support rods 3 are set at a predetermined angle, one end of the two support rods 3 is hinged on the support seat 2, and the other end is hinged on the inner formwork assembly 4, and the two support rods 3 and the inner formwork assembly 4 are surrounded to form a stable triangular structure to ensure the stability of the inner formwork assembly 4. Among them, the support seat 2 can be fixed by two rows of short steel bars pre-buried in the road pavement layer, and the short steel bars are removed after the formwork is removed.

[0045] In order to reduce the leakage of slurry, the guardrail construction template provided in this embodiment, the outer template assembly 7 also includes a leak-proof bottom plate 8, which is fixedly connected to the bottom end of the outer template assembly 7, and can be formed by bending the bottom ends of the outer template body 701 and the second inner guardrail plate 702 inward, and the angle between the leak-proof bottom plate 8 and the outer template body 701 can be set to 90 degrees. Continuing to take the construction object as a bridge as an example, during construction, the leak-proof bottom plate 8 extends to the bottom of the bridge flange plate 1 and is connected to the adjustment and positioning assembly.

[0046] In order to further reduce the leakage, a sealing pad can be provided between the anti-leakage bottom plate 8 and the adjustment plate 9, and a dodge hole is provided on the sealing pad for the adjustment bolt 10 to pass through. High-viscosity double-sided foam tape can also be pasted on the joints of the guardrail construction templates. Example 3

[0047] On the basis of Embodiment 1 and Embodiment 2, in this embodiment, the side surfaces of the inner template body 401 and / or the outer template body 701 are provided with reinforcing ribs 11. Optionally, the reinforcing ribs 11 include flat steel.

[0048] Therefore, the strength of the inner formwork body 401 and the outer formwork body 701 can be ensured by the first inner guardrail plate 402, the first outer guardrail plate 403 and the reinforcing ribs 11 on the inner formwork body 401 and the second inner guardrail plate 702, the second outer guardrail plate 703 and the reinforcing ribs 11 on the outer formwork body 701, and can fully withstand the lateral pressure and other loads generated by the guardrail slurry therebetween.
