Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and relates to the construction of road sidewalk guardrails, specifically to an X-shaped sidewalk guardrail template structure. Background Technology

[0002] Concrete guardrails on the outer side of road or bridge pedestrian walkways typically consist of two horizontal beams with vertical supports spaced at regular intervals between them. Prefabrication of this type of linear guardrail, combining horizontal and vertical elements, is relatively easy due to the simple assembly of multiple longitudinal and transverse formwork panels. However, in recent years, driven by the dual need to improve both the aesthetics and safety of road traffic facilities, X-shaped guardrails have become increasingly popular. Figure 1 The diagram shows a structural schematic of an X-shaped guardrail segment 100, which includes two horizontal beams 101. In addition to vertical supports 102, X-shaped diagonal supports 103 are also spaced between the two horizontal beams. When this type of guardrail is prefabricated, the formwork installation process is relatively complicated. In addition to the longitudinal and transverse formwork, multiple diagonal support formworks are required. Moreover, due to the lack of specialized formwork positioning and support devices, it is difficult to achieve ideal connection of the formwork at the intersection nodes, which can easily lead to problems such as grout leakage, formwork bulging, and cracks, affecting the quality of the finished guardrail. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a template structure specifically for X-type pedestrian guardrails, thereby achieving high-quality prefabrication of the guardrails.

[0004] The technical solution of this utility model is as follows:

[0005] An X-shaped pedestrian guardrail template structure, characterized in that it includes two outer longitudinal templates, four inner longitudinal templates, two inner transverse templates, four first V-shaped templates, two second V-shaped templates, two third V-shaped templates, and four end templates;

[0006] The two outer longitudinal templates are arranged in parallel with a certain distance between them;

[0007] Four inner longitudinal templates are respectively set in two directions parallel to the two outer longitudinal templates on the inner side. Each inner longitudinal template is fixedly connected to both ends of the first V-shaped template. The top of each inner longitudinal template extends a certain length of connecting part in the longitudinal direction. The connecting parts of one end of the two inner longitudinal templates on each side are connected by bolts.

[0008] Two inner transverse templates are set between the inner longitudinal templates on both sides in a direction perpendicular to the inner longitudinal templates and with a certain distance between them. One side of each inner transverse template is fixedly connected to both ends of a second V-shaped template.

[0009] The four end templates are respectively set at both ends of the two outer longitudinal templates in a direction perpendicular to the outer longitudinal templates. The two end templates at each end are respectively connected to both ends of the third V-shaped template by bolts. In addition, each end template is also respectively connected to the end of an outer longitudinal template and the connecting part of the other end of an inner longitudinal template by bolts.

[0010] The outer corners of the first V-shaped templates connected to each of the two inner longitudinal templates, which are parallel to the inner transverse templates, are set opposite each other with a certain distance. The outer corners of the two second V-shaped templates are respectively set opposite to the outer corners of the two third V-shaped templates with a certain distance.

[0011] This utility model features multiple V-shaped templates, eliminating the need for separate supports during template installation. Installation and disassembly are convenient and quick, simplifying the design and installation process of temporary support systems compared to traditional methods. In terms of quality control, there is no leakage or bulging at the joints, resulting in a low rate of cracks in the finished product. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of an X-shaped concrete guardrail;

[0013] Figure 2 This is a schematic diagram of the overall structure of the template of this utility model;

[0014] Figure 3 This is a schematic diagram of the template's split structure. Detailed Implementation

[0015] like Figure 2 , Figure 3 As shown, this utility model includes two outer longitudinal templates 1, four inner longitudinal templates 2, two inner transverse templates 3, four first V-shaped templates 4, two second V-shaped templates 5, two third V-shaped templates 6, and four end templates 7.

[0016] The two outer longitudinal templates 1 are arranged in parallel with a certain distance between them. In specific implementation, the distance between them depends on the width of the X-shaped pedestrian guardrail to be prefabricated.

[0017] Four inner longitudinal templates 2 are respectively set on the inner side of two outer longitudinal templates 1 in a direction parallel to the outer longitudinal templates. Each inner longitudinal template 2 is fixedly connected to both ends of the first V-shaped template 3. A certain length of connecting part 21 extends from the top of both ends of each inner longitudinal template 2 in the longitudinal direction. The connecting parts 21 at one end of the two inner longitudinal templates on each side are connected by bolts.

[0018] Two inner transverse templates 3 are set between the inner longitudinal templates on both sides in a direction perpendicular to the inner longitudinal templates and with a certain distance. In specific implementation, the distance is determined according to the width of the vertical bracing between the two horizontal beams of the guardrail; one side 3 of each inner transverse template is fixedly connected to both ends of a second V-shaped template 5.

[0019] The four end templates 7 are respectively set at both ends of the two outer longitudinal templates in a direction perpendicular to the outer longitudinal templates. The two end templates 7 at each end are respectively connected to both ends of the third V-shaped template 6 by bolts. Moreover, each end template 7 is also respectively connected to the end of an outer longitudinal template 1 and the connecting part 21 at the other end of an inner longitudinal template by bolts.

[0020] The outer corners of the first V-shaped template 4 connected to each of the two inner longitudinal templates in a direction parallel to the inner transverse template are set opposite each other and have a certain distance between them. The outer corners of the two second V-shaped templates 5 are respectively set opposite to the outer corners of the two third V-shaped templates 6 and have a certain distance between them.

[0021] The above appendix Figure 2 and 3 In order to more clearly show the structure of the template itself, the bolts are not drawn at each bolt connection position, but the screw holes 8 on the template are shown. Those skilled in the art can know that each bolt is installed through the screw holes on the template.

[0022] In specific implementation of this utility model, in order to ensure accurate positioning and firm installation of the end templates, an end template positioning plate 9 can be set at the bottom of the two end templates 7 at each end. The end template positioning plate 9 includes a horizontally arranged pad 91, a vertically arranged upward protruding limiting plate 92 on the front side of the pad, and two limiting blocks 93 on the top surface of the pad. A gap with the same thickness as the end template is provided between the limiting plate 92 and the limiting blocks 93. The bottom of the two end templates 7 at each end is respectively inserted into the gap between the limiting plate 92 and the two limiting blocks 93.

[0023] In a specific implementation of this utility model, in order to facilitate the demolding of the end template, a lifting ring 10 can be provided at the top of each end template 7.

[0024] This utility model is used for prefabrication. Figure 1 When constructing the X-shaped pedestrian guardrail 100, the formwork is assembled on the hardened ground. Concrete is poured between the outer longitudinal formwork 1 and the inner longitudinal formwork 2 to form the guardrail's crossbeam 101. Concrete is poured between the two inner transverse formworks 3 to form the vertical brace 102 in the middle of the crossbeam. Concrete is poured between the first V-shaped formwork 4, the second V-shaped formwork 5, and the third V-shaped formwork 6 to form the X-shaped diagonal brace 103 of the guardrail. After the concrete reaches the demolding strength, the end formwork and the outer longitudinal formwork are removed in sequence, and then the remaining formwork is removed, thus completing the prefabrication of one X-shaped guardrail segment.
