Description

Technical Field

[0001] This disclosure pertains to the field of guardrail protection engineering construction, specifically relating to a positioning device for embedded parts in concrete guardrails. Background Technology

[0002] With the continuous development of highway engineering and the constant improvement of road infrastructure, crash barriers are designed into all road surfaces to ensure road safety. Currently, New Jersey crash barriers are widely used in highway crash barrier design due to their advantages of convenient and quick production and installation. The crash barriers have pre-embedded bolts, and multiple crash barriers are connected longitudinally using steel profiles. The pre-embedded bolts are used to connect the steel profiles between the crash barriers. When multiple crash barriers are longitudinally joined, the installation position of the pre-embedded parts is crucial to ensure a smooth alignment of the barrier ends.

[0003] For example, the positioning device for positioning and adjusting the embedded parts of bridge railings disclosed in CN222990568U adjustably installs the positioning plate with the embedded parts on the frame, and at the same time, multiple lifting supports for erecting the frame adjustably erect the frame on the templates on both sides of the bridge railing. This allows the installation position and depth of the embedded parts to be quickly adjusted according to the construction situation when erecting the embedded parts, so that the embedded parts can be quickly and accurately embedded in the bridge railing according to the design requirements.

[0004] However, the aforementioned devices have numerous structures and require extensive assembly and precise leveling before construction, which takes up a considerable amount of preparation time. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a positioning device for embedded concrete guardrail components, which solves the problem that existing technologies require a long construction preparation time due to their complex structure, extensive assembly, and precise leveling.

[0006] The objective of this disclosure can be achieved through the following technical solutions:

[0007] A positioning device for embedded parts in a concrete guardrail includes: a mold and a support frame;

[0008] The upper end of the mold is provided with a support frame, and a vertical through hole is opened on the side of the support frame away from the mold.

[0009] The diameter of the through hole is adapted to the diameter of the embedded part;

[0010] The embedded part is provided with a through hole, and a fixing part is provided between the upper end of the embedded part and the support frame;

[0011] The fastener is used to restrict the axial movement of the embedded part.

[0012] In some disclosures, the fastener includes a first limiting part and a second limiting part, with the first limiting part and the second limiting part fixed to the upper and lower sides of the through hole respectively, and the width of the first limiting part and the second limiting part being greater than the inner diameter of the through hole.

[0013] In some disclosures, the fastener is threaded, the upper end of the embedded part is fixed with a threaded protrusion, and the first limiting part and the second limiting part are nut seats adapted to the threaded protrusion.

[0014] In some disclosures, the fastener is a clamp structure, and both the first limiting part and the second limiting part are clamp structures.

[0015] In some disclosures, the support frame has a reserved axial gap between the end with the through hole and the upper end face of the mold.

[0016] In some disclosures, the fastener also includes a mudguard, and the mudguard is fixed between the second limiting portion and the through hole.

[0017] In some disclosures, the support frame and the mold are detachable structures.

[0018] In some disclosures, the support frame has a first mounting hole fixed on the side away from the through hole, and the upper end face of the mold has a second mounting hole corresponding to the mounting hole, and the support frame is provided with fixing bolts that pass through the first mounting hole and the second mounting hole.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0021] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0022] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0023] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0024] The beneficial effects of this disclosure are:

[0025] 1. The embedded part is initially positioned in two dimensions through the through holes on the support frame, and the first and second limiting parts set at the top and bottom form a rigid clamp, effectively restricting the axial (vertical) and radial (tilt) degrees of freedom of the embedded part. This helps to make the embedded part more stable in position and more accurate in verticality in the dynamic casting environment, and helps to improve the accuracy of bolt hole positions;

[0026] 2. When the support frame is located above the concrete, it will interfere with the position of the concrete block when the solidified concrete is removed from the mold. Therefore, the support frame and the mold need to be disassembled frequently. This device opens a second mounting hole on the mold corresponding to the position of the support frame, so that each time the embedded part is installed, the support frame only needs to be installed in the same position of the mold. At this time, the bottom surface of the support frame is coplanar with the upper surface of the mold, which can keep the central axis of the through hole perpendicular to the upper surface of the concrete.

[0027] 3. The mudguard installed between the second limiting part and the through hole can effectively prevent cement slurry from seeping in and solidifying between the through hole and the embedded part. This can not only improve the service life of the through hole on the support frame, but also make it easier to remove the support frame from the embedded part. Attached Figure Description

[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0036] Please refer to Figures 1 to 5 A positioning device for embedded parts of concrete guardrails;

[0037] Includes: mold 1, support frame 2;

[0038] The upper end of the mold 1 is provided with a support frame 2, and the support frame 2 is provided with a vertical through hole 21 on the side away from the mold 1;

[0039] The diameter of the through hole 21 is matched with the diameter of the embedded part 3;

[0040] The embedded part 3 is provided through the through hole 21, and a fixing part 4 is provided between the upper end of the embedded part 3 and the support frame 2;

[0041] The fastener 4 is used to restrict the axial movement of the embedded part 3.

[0042] When in use, the embedded part 3 is inserted vertically from above and passes through the through hole 21.

[0043] The embedded part 3 is fixed to the support frame 2 using the fastener 4, and at this time the side wall of the embedded part 3 is in contact with the side wall of the through hole 21. The embedded part 3 is kept vertically downward by the fastener 4, and the movement of the embedded part 3 sinking or floating during the pouring process is reduced by fixing it with the fastener 4.

[0044] The embedded part 3, which is constrained by the inner wall of the through hole 21, keeps the object vertical and reduces the tilt angle.

[0045] After the concrete is poured, vibrated and solidified, first loosen the fastener 4, then disassemble the support frame 2 and the fastener 4, and move it to the next work station for reuse.

[0046] Please refer to Figures 1 to 5 The fastener 4 includes a first limiting part and a second limiting part. The first limiting part and the second limiting part are fixed on the upper and lower sides of the through hole 21 respectively, and the width of the first limiting part and the second limiting part is greater than the inner diameter of the through hole 21.

[0047] When in use, the lower end of the embedded part 3 first penetrates through the through hole 21 and is vertically inserted into the concrete along the inner wall of the through hole 21 until the embedded part 3 reaches the pre-embedded position. At this time, the first limiting part and the second limiting part are fixed on the outside of the embedded part 3. At the same time, the side walls of the first limiting part and the second limiting part are respectively attached to the upper end and the lower end of the through hole 21, thereby limiting the axial displacement of the embedded part 3. The position of the embedded part 3 is further limited by the inner wall of the through hole 21. This helps to reduce the situation where the embedded part 3 tilts or floats due to the floating of concrete during the concrete vibration process. Furthermore, by setting limiting parts on both the upper and lower sides of the through hole 21, the upward and downward distances of the embedded part 3 in the axial direction can be reduced, thereby further improving the stability of the position of the embedded part 3 and the distance of position change of the embedded part 3 before and after the concrete solidifies.

[0048] Example 1

[0049] Please refer to Figures 1 to 3 The fastener 4 is threaded, and the upper end of the embedded part 3 is fixed with a threaded protrusion 41. The first limiting part and the second limiting part are nut seats 42 that are adapted to the threaded protrusion 41.

[0050] When in use, tighten the second limiting part on the outside of the threaded protrusion 41, then insert the embedded part 3 into the concrete at an angle, and then insert the upper end of the embedded part 3 into the through hole 21 from the bottom of the through hole 21. Then adjust the embedded part 3 to a suitable position. At this time, tighten the nut seat 42 from the upper end of the embedded part 3 to the outside of the embedded part 3. Then adjust the position of the nut seat 42 so that the side wall of the nut seat 42 fits with the upper and lower end faces of the through hole 21. Use the threaded engagement to fix the embedded part 3 on the through hole 21.

[0051] Example 2

[0052] Please refer to Figures 4 to 5 The fastener 4 is a clamp structure, and both the first limiting part and the second limiting part are clamp 44 structures;

[0053] At this time, any end of the embedded part 3 is inserted through the through hole 21. After the embedded part 3 reaches the embedded position, the clamp 44 is fixed to the outside of the embedded part 3 by the tightening device on the clamp 44. The locking device of the clamp 44 can also be a connecting bolt. The clamp is fixed to the outside of the embedded part 3 by the connecting bolt, and the embedded part 3 is restricted from floating up and down by the rigid resistance with the through hole 21.

[0054] Please refer to Figure 1 The support frame 2 has a reserved axial gap between one end with a through hole 21 and the upper end face of the mold 1;

[0055] The axial gap is not less than 5cm to avoid direct contact between the concrete and the through hole 21, thereby preventing blockage of the through hole;

[0056] The axial gap is used to raise the fixing point between the support frame 2 and the embedded part 3, which helps to reduce the adhesion of concrete to the inside of the through hole 21 during the concrete vibration leveling process, which would cause the concrete, support frame 2 and embedded part 3 to stick together.

[0057] Please refer to Figures 1 to 5 The fixing component 4 also includes a mudguard 43, and the mudguard 43 is fixed between the second limiting part and the through hole 21. During the concrete pouring and vibration process, the mudguard 43 is used to block the through hole 21 and the concrete, limiting the splashing or seeping of cement slurry into the gap between the embedded part 3 and the through hole 21. This helps to keep the through hole 21 clean, reduce the adhesion of cement residue in the through hole 21, and help to extend the service life of the support frame 2.

[0058] Please refer to Figures 1 to 2 The support frame 2 and the mold 1 are detachable structures;

[0059] When demolding concrete from above mold 1, avoid setting the support frame 2 to protrude from mold 1 and interfere with the demolding process.

[0060] Please refer to Figures 1 to 2 The support frame 2 has a first mounting hole 5 fixed on the side away from the through hole 21, and the upper end face of the mold 1 has a second mounting hole 6 corresponding to the mounting hole, and the support frame 2 is provided with a fixing bolt 7 that passes through the first mounting hole 5 and the second mounting hole 6.

[0061] In use, align the central axes of the first mounting hole 5 and the second mounting hole 6, then pass the fixing bolt 7 through the first mounting hole 5 and the second mounting hole 6, and tighten the fixing bolt 7 through the first mounting hole 5 and the second mounting hole 6 with a nut. In this way, the support frame 2 is detachably fixed to the mold 1. After the concrete has solidified, the support frame 2 can be easily disassembled from the mold 1 by removing the fixing bolt 7 and the nut. When demolding the concrete from above the mold 1, the support frame 2 is set to avoid protruding from the mold 1 and interfering with the demolding of the concrete.

[0062] Furthermore, the mold 1 has a first mounting hole 5 and the support frame 2 has a second mounting hole 6 corresponding to its position, so that each time the embedded part 3 is installed, the support frame 2 only needs to be installed in the same position on the mold 1, thereby reducing the installation time of the support frame 2 each time.
