Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a quick fixing device. Background Technology

[0002] Guardrail templates are standard molds used for installing guardrails during construction. They can help construction workers install guardrails quickly and accurately, saving construction time while ensuring the aesthetics and consistency of the guardrails.

[0003] Guardrail formwork is divided into inner and outer formwork. The inner formwork is primarily used to create the internal structure of the guardrail, ensuring its shape and dimensional accuracy. It is typically used in conjunction with the guardrail's reinforcing steel frame to ensure the guardrail maintains its intended shape after concrete pouring. The outer formwork is mainly responsible for forming the guardrail's external surface, ensuring a smooth and even appearance. It also resists the lateral pressure generated during concrete pouring, maintaining the guardrail's verticality and straightness.

[0004] After the inner and outer templates are hoisted to the location where they need to be installed, the tops of the inner and outer templates need to be aligned after the bottom feet are fixed to ensure that the shape and size of the guardrail meet the requirements. However, currently, the top alignment is mainly done by tie rods, which is complicated, time-consuming and labor-intensive. Utility Model Content

[0033] Currently, the top alignment of the inner template 60 and the outer template 50 is mainly achieved by using tie rods. The tie rods require drilling holes at corresponding positions on the inner template 60 and the outer template 50, then passing the tie rods through these holes, installing nuts at both ends of the tie rods and tightening them with a wrench, and then using a spirit level or laser level to check the verticality and flatness of the templates. This method is complicated, time-consuming and labor-intensive.

[0034] To address this, the inventors have proposed the following embodiments for improvement. The following detailed description, in conjunction with the accompanying drawings, outlines some implementation methods of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] refer to Figure 1 and Figure 2This application discloses a quick fixing device, which includes a fixing base 10 and an anchor 20. The fixing base 10 is used to install on the top of the outer template 50. The anchor 20 includes an anchor body 21 and an anchor part 22. The anchor body 21 is rotatably connected to the fixing base 10, and the anchor part 22 is connected to the end of the anchor body 21 away from the fixing base 10. The length extension direction of the anchor part 22 forms an angle with the length direction of at least a portion of the anchor body 21. The anchor part 22 is used to be embedded in the fixing groove on the top of the inner template 60.

[0036] In this way, after the bottom 11 of the inner template 60 and the outer template 50 are hoisted to the required installation position and the feet are aligned, the fixing base 10 is installed on the top of the outer template 50. The position of the fixing groove on the top of the inner template 60 is located, and the anchor body 21 is rotated and hammered downwards with a hammer or other tools to make the anchor part 22 insert into the fixing groove. This achieves relative fixation of the top of the inner template 60 and the outer template 50, which facilitates the installation of the guardrail and ensures that the shape and size of the guardrail after installation meet the requirements. After the guardrail is installed, it is only necessary to knock the anchor body 21 upwards in the opposite direction to make the anchor part 22 exit the fixing groove. Then, the fixing base 10 is removed from the outer template 50 to complete the removal of the template fixing. This is convenient, simple, quick, time-saving, labor-saving, and does not affect the secondary use of the template.

[0037] Specifically, the fixed base 10 includes a bottom 11 and two connecting parts 12 connected to the bottom 11 and opposite to each other. The bottom 11 is used to connect to the top of the outer template 50, thereby realizing the fixation of the overall quick fixing device on the top of the outer template 50. The other end of the anchor body 21 is located between the two connecting parts 12 and is hinged to the two connecting parts 12.

[0038] The fixed base 10 is formed by overlapping and welding one side of two angle steels. The angle steels are usually L-shaped. The overlapping area of ​​the two angle steels forms the bottom 11, and the other side of the two angle steels forms two connecting parts 12 respectively.

[0039] The bottom 11 is provided with a second through hole 111, that is, the overlapping area of ​​the two angle steels is drilled to form the second through hole 111. Fasteners such as screws are inserted through the second through hole 111 and locked into the threaded hole at the top of the outer template 50, thereby realizing the connection and fixation between the fixed base 10 and the outer template 50.

[0040] The connecting part 12 is provided with a through hole 120, the anchor body 21 is provided with a through hole, and the hinge shaft passes through the two first through holes 120 and the through hole, thereby realizing the rotatable connection (hinged connection) between the anchor 20 and the fixed base 10.

[0041] In detail, the hinge shaft includes a bolt 30, the shank of the bolt 30 passing through two first through holes 120 and a through hole, a nut being fitted onto the shank, and the heads of the nut and the bolt 30 being located on opposite sides of the two connecting parts 12, thereby achieving the hinge connection between the anchor 20 and the fixed base 10.

[0042] The anchoring body 21 includes a first connecting segment 210 and a second connecting segment 221 connected at an angle, for example, the first connecting segment 210 and the second connecting segment 221 are at a right angle. The first connecting segment 210 is rotatably connected to the fixed base 10, that is, the first connecting segment 210 is provided with a through hole for the rod portion of the bolt 30 to pass through. The anchoring part 22 is connected to the end of the second connecting segment 221 to ensure that the anchoring part 22 can be inserted into the fixing slot after the anchoring body 21 is rotated down.

[0043] The anchoring part 22 has a tapered surface 220, and the outer diameter of the tapered surface 220 gradually increases from the end of the anchoring part 22 away from the anchoring body 21 to the end closer to the anchoring body 21, so that the anchoring part 22 can be better inserted into the fixing slot.

[0044] The anchor body 21 is a steel plate. The part where the bolt 30 rod passes through is trimmed and ground into a circle. The other parts are appropriately trimmed and ground to prevent obvious sharp edges. The anchor part 22 is a component with a conical end in the front half and a square end in the back half. It is fully welded to the anchor body 21 according to the structural dimensions required by the concrete component to form an L-shaped anchor 20.

[0045] The quick-fixing device also includes a protective cover 40, which is connected to the anchor body 21 in the area between the two connecting parts 12. Specifically, the protective cover 40 includes a support part 41 and a cover body 42 connected to one end of the support part 41. The other end of the support part 41 is connected to the anchor body 21. A distance is left between the cover body 42 and the connecting parts 12 to avoid interference between the cover body 42 and the connecting parts 12, which would affect the rotation of the anchor 20. The protective cover 40 protects the connection between the anchor 20 and the fixed base 10 during the installation of the guardrail, preventing the fixed base 10 from being softened by the concrete during pouring, and ensuring the effective rotation of the anchor 20. The cover body 42 and the support part 41 can be made of steel plate and are welded together. The support part 41 is welded to the anchor body 21.

[0046] It should be noted that since materials such as angle steel, bolts 30, steel plates, and gaskets can be obtained directly on the construction site, welding, drilling, and other operations can be performed on-site to create the quick fixing device in this embodiment, without the need for additional purchases or custom orders, thus saving costs.

[0047] In summary, this application discloses a quick fixing device. After the bottom 11 of the inner template 60 and the outer template 50 are hoisted to the location to be installed and the feet are aligned, the fixing base 10 is installed on the top of the outer template 50. The position of the fixing groove on the top of the inner template 60 is located, and the anchor body 21 is rotated and hammered downwards with a hammer or other tools to make the anchor part 22 insert into the fixing groove. This achieves relative fixation of the tops of the inner template 60 and the outer template 50, which facilitates the installation of the guardrail and ensures that the shape and size of the guardrail after installation meet the requirements. After the guardrail is installed, it is only necessary to hammer the anchor body 21 upwards in the opposite direction to make the anchor part 22 exit the fixing groove. Then, the fixing base 10 is removed from the outer template 50 to complete the removal of the template fixing. It is convenient, simple, quick, and saves time and effort.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
