Description

Technical Field

[0001] This utility model belongs to the field of guardrail template technology, and in particular relates to an anchor-free guardrail template. Background Technology

[0002] In highway and bridge construction, guardrail formwork is the core equipment for forming concrete guardrails. It consists of components such as bottom mold, side mold, and end mold, which are spliced ​​and fixed to form a cavity. Its structural design directly affects the construction quality and project progress of the guardrail, making it a key tool for infrastructure construction.

[0003] Traditional concrete guardrails generally rely on anchoring structures for fixation, requiring embedded parts, tie rods, or external counterweights to form constraints. This design results in a rigid connection between the concrete guardrail and the foundation structure, which not only increases the overall weight of the concrete guardrail but also limits its application flexibility in complex terrain.

[0004] In addition, some anchor-free guardrails have protruding feet at the bottom with through-holes inside, making it difficult to achieve a one-piece and simplified design for the guardrail template and to ensure consistent quality in the production of guardrails. Utility Model Content

[0005] In view of the above problems, this utility model aims to solve the problems of cumbersome installation and poor connection stability of existing guardrail templates, and provides an anchor-free guardrail template. Through the design of a detachable upper mold and upper cover plate, the template installation process is simplified, ensuring the quality and efficiency of guardrail construction.

[0006] The present invention adopts the following technical solution:

[0007] The anchor-free guardrail template includes a bottom mold, with side molds and end molds rotatably arranged on the long and short sides of the bottom mold, respectively. The side molds and end molds are detachably connected to each other. A pair of side molds are formed on the top of the side molds. Detachable upper end molds are installed on both sides of the side molds at the same position above the side molds. The top of the side molds and upper end molds at the same position is provided with an upper cover plate.

[0008] Furthermore, an insertion port is provided at the center of the upper cover plate.

[0009] Furthermore, the socket is formed with a positioning top sleeve with a constricted top.

[0010] Furthermore, the bottom surface of the upper cover plate has a protruding plate.

[0011] Furthermore, the side mold is provided with a conical hole, and the bottom surface of the upper cover plate is provided with a matching pin for each conical hole.

[0012] Furthermore, the upper surface of the bottom mold has a circular groove or a boss.

[0013] Furthermore, eye bolts are provided at all four corners of the upper cover plate.

[0014] Furthermore, the top of the upper cover plate is bent upwards around all four sides to form a baffle, and a reinforcing plate is formed on the upper cover plate between the baffle and the positioning top sleeve.

[0015] The beneficial effects of this utility model are:

[0016] 1. By installing a detachable upper mold above the side mold and edge mold, the final mold assembly of the guardrail template is achieved, simplifying the installation process, saving installation time, and improving construction efficiency.

[0017] 2. During the assembly of the upper cover plate, the pins on the bottom surface of the upper cover plate are aligned with the tapered holes of the side mold. The upper cover plate is dropped vertically, and the taper of the pins and the tapered holes achieves automatic centering.

[0018] At the same time, after the top cover plate falls vertically, the top of the round tube can pass through the positioning top sleeve. The positioning top sleeve with a constricted top can play the role of positioning the round tube, ensuring that the round tube remains stationary during the cement mortar setting process.

[0024] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0026] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0027] Combination Figure 2-4As shown, the anchor-free guardrail template includes a bottom mold 1, and side molds 2 and end molds 3 are rotatably arranged on the long and short sides of the bottom mold 1, respectively. The side molds 2 and end molds 3 are detachably connected to each other. The feature is that a pair of side molds 4 are formed on the top of the side molds 2, and detachable upper end molds 5 are installed on both sides of the side molds 4 above the side molds 2 at the same position. The top of the side molds 4 and the upper end molds 5 at the same position are provided with an upper cover plate 6.

[0028] In highway and bridge construction, guardrail formwork is the core equipment for forming concrete guardrails. It consists of components such as bottom mold, side mold, and end mold, which are spliced ​​and fixed to form a cavity. Its structural design directly affects the construction quality and project progress of the guardrail, making it a key tool for infrastructure construction.

[0029] The bottom formwork serves as the main carrier of the anchor-free guardrail template. A pair of side formworks are rotatably mounted on the bottom formwork, and a pair of end formworks are also mounted on it. Both ends of the end formworks can be connected to the side formworks via a locking mechanism. Alternatively, bolts can be used for fixing; this connection method is existing technology and will not be described in detail here.

[0030] When in use, the bottom mold is placed horizontally on the construction reference surface. First, the two side molds are flipped upwards to a vertical state as required. At the same time, the end molds at both ends are rotated inwards so that the side edges of the end molds fit with the ends of the side molds. Then, the two ends of the end molds are fixed to the side molds on the same side by means of locking. At this time, the end molds and side molds form a closed rectangular frame.

[0031] Next, fix the upper mold to the top of the two side molds and / or the side wall of the edge mold using bolts. After the upper mold is installed, the two upper molds are in contact with the sides of the edge molds. Then, install the upper cover plate on the upper mold and the edge molds as required, with the bottom surface of the upper cover plate in contact with the top surface of the upper mold and the edge mold.

[0032] As a specific structure, the bottom surface of the upper cover plate 6 has a protruding plate 7, and the center of the upper cover plate 6 has an insertion port 8. The insertion port 8 forms a positioning top sleeve 9 with a constricted top.

[0033] Figure 1 As shown, the anchor-free guardrail 10 has a pair of through-hole fixed circular openings 11. Before installing the upper cover plate on the upper mold and side mold, a circular tube needs to be placed inside the mold. To facilitate the subsequent demolding of the circular tube from the anchor-free guardrail, a release agent can be applied to the circular tube first. After the circular tube is placed as required, cement mortar is poured into the forming cavity. Finally, the upper cover plate is assembled on the upper mold and side mold, and the circular tube passes through the positioning top sleeve 9. The cement mortar is vibrated and leveled, and the cement mortar is allowed to set and form the anchor-free guardrail.

[0034] like Figure 5The bottom mold has a circular groove or a boss on its upper surface (marked as 17). When positioning and installing the round tube, simply insert the bottom of the round tube into the corresponding circular groove or boss.

[0035] like Figure 3-4 Since the side mold 4 has a through conical hole 12, the bottom surface of the upper cover plate 6 has a matching pin 13 opposite to each conical hole 12. Eye bolts 14 are provided at each of the four corners of the upper cover plate.

[0036] During the assembly of the top cover plate, it can be hoisted above the side mold using eye bolts. Align the bottom pins with the tapered holes of the side mold, and the top cover plate will fall vertically. The taper of the pins with the tapered holes will achieve automatic centering.

[0037] During the assembly of the top cover plate, because the spigot 8 has a constricted positioning top sleeve 9, even if the position of the round tube is slightly off, the top of the round tube can still pass through the positioning top sleeve after the top cover plate is dropped vertically. Since the top of the positioning top sleeve has a constricted structure, it can position the round tube and ensure that the round tube remains stationary during the cement mortar setting process.

[0038] In this structure, such as Figure 2 The top of the upper cover plate 6 is bent upwards around all four sides to form baffles 15, and a reinforcing plate 16 is formed on the upper cover plate 6 between the baffles and the positioning top sleeve. By setting baffles and reinforcing plates on the upper cover plate, the structural strength of the upper cover plate is enhanced and the service life of the template is extended.

[0039] Finally, after the concrete reaches the design strength, first lift the top cover plate using eye bolts, then remove the upper mold from the side molds. Next, remove the round pipe, then release the locks between the end mold and the side molds. Rotate the end mold outwards 90°, and then flip the two side molds downwards along the rotation axis of the bottom mold until they are horizontal. This completes the overall demolding of the guardrail. The demolded, anchor-free guardrail is as follows: Figure 1 As shown, the feet 101 of the anchorless guardrail 10 are positioned upwards. Under the action of the convex plate, the feet 101 form a bottom cavity 102 inwards, and a shock-absorbing pad can be placed inside the bottom cavity 102. When using and installing the anchorless guardrail, the two bases are positioned downwards, and then the guardrail is inserted into the fixed circular opening 11 formed by the guardrail.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
