Description

Technical Field

[0001] The utility model relates to the field of buildings, in particular to an embedded component which is fixedly installed on the inner wall of a template and allows the Hafen rail to be closely fitted to the template. Background Art

[0002] HALFEN CABLE, also known as HALFEN GROOVE, is a professional embedded part for construction. HALFEN CABLE consists of a main part and an anchor. The main part is generally a C-shaped channel steel. The anchor is generally an anchor nail. There are at least two anchor nails on the back of the main part. The front of the main part is a groove with closed ends. Before pouring concrete, the HALFEN CABLE is embedded in the pouring cavity. The main part of the HALFEN CABLE is arranged vertically, and the front of the main part fits the inner wall of the formwork. After pouring concrete, the HALFEN CABLE and the reinforced concrete become a whole.

[0003] The pre-embedded construction of the Hafin Rail requires that the actual position of the Hafin Rail be controlled to be the designed position, and at the same time, the front of the main part of the Hafin Rail be controlled to fit closely with the formwork to avoid a gap between the Hafin Rail and the formwork. Generally, the Hafin Rail can be fixed to the formwork or the structural steel bar. The Hafin Rail is fixed to the structural steel bar, which is conducive to improving the bearing capacity of the Hafin Rail. However, since the Hafin Rail is not fixed to the formwork, a gap is likely to appear between the Hafin Rail and the formwork, causing concrete slurry to enter the gap, and even the concrete to bury the entire Hafin Rail. The entire Hafin Rail is buried in concrete. After the formwork is removed, the poured concrete needs to be manually excavated, which not only wastes materials, but also increases labor costs, and may also cause the reinforced concrete structure to fail to meet the design requirements. In addition, the Hafin Rail is installed on the structural steel bar, and the installation position of the Hafin Rail will inevitably be affected by the structural steel bar, and the Hafin Rail may not be fixed to the designed position.

[0004] Fixing the HALFEN rail to the template is conducive to keeping the HALFEN rail and the template in close contact. For example, the patent with the authorization announcement number CN 207513205U discloses a HALFEN slot embedded part installation and fixing device, including a T-shaped clamp that passes through the template and is clamped in the clamping groove of the HALFEN slot, the T-shaped clamp includes a cylindrical straight rod and a T-shaped wing vertically arranged at the upper end of the straight rod, and a plurality of through holes are opened along the length direction of the HALFEN slot at the design layout position of the HALFEN slot on the template for the cylindrical straight rod of the T-shaped clamp to pass through, and a wedge is provided on the rod body of the straight rod section of the T-shaped clamp protruding from the outside of the template and intersecting with the template, and the two ends of the T-shaped wing are respectively pressed on the inner side of the folded edges at the two ends of the bottom of the HALFEN slot, and fixed by a wedge in the wedge. For another example, the patent with the authorization announcement number CN 207512776 U discloses a device for installing and fixing the embedded parts of the Halfen trough, including a plurality of metal clips sleeved on the outer wall of the Halfen trough slot, the metal clips including a U-shaped clip adapted to the shape and size of the outer wall of the Halfen trough and steel edges vertically arranged on the edges of both sides of the U-shaped clip, the steel edges are provided with self-tapping screw holes, and the self-tapping screws pass through the steel edges to connect and fix with the template. The above two patents fix the Halfen trough from the inside of the slot and from the outside of the Halfen trough, but do not fix the Halfen trough in the length direction of the slot, and the Halfen trough can move along the length of the slot. In addition, the T-shaped clips and U-shaped clips in the above two patents only play the role of fixing the Halfen trough, and cannot improve the stability of the Halfen trough in the reinforced concrete structure, nor can they improve the bearing capacity of the Halfen trough. Utility Model Content

[0005] The utility model provides a HALFEN rail embedded component, which aims to improve the stability of the HALFEN rail after being installed on a template and to improve the bearing capacity of the HALFEN rail.

[0006] The technical solution adopted by the utility model is: a Hafen rail embedded component, including a Hafen rail and a fixing plate, the Hafen rail including a main body and an anchoring piece, a front side of the main body being provided with a slot closed at both ends, and wing plates are respectively provided on both sides of the main body along the length direction of the slot, and the sides of the two wing plates facing away from the anchoring piece are both flush with the front side of the main body, and at least two anchoring pieces are fixed to the back side of the main body, and each anchoring piece is arranged at intervals along the length direction of the main body; two opposite plate surfaces of the fixing plate are respectively the front side and the back side, and at least two through mounting holes are provided between the front side and the back side, and each mounting hole is respectively equipped with an adapted screw or bolt, and the fixing plate has a U-shaped notch, and L-shaped hanging platforms are respectively provided on both sides of the notch, and the length directions of the two hanging platforms are parallel to each other, and the two hanging platforms both protrude toward the back side of the fixing plate, and a mounting groove of the Hafen rail is formed between the two hanging platforms, and the depth of the hanging platform does not exceed the thickness of the wing plate of the Hafen rail, and the distance between the two hanging platforms is consistent with the distance between the outer edges of the two wing plates of the Hafen rail.

[0007] In order to improve the bonding strength between the fixing plate and the concrete, further, at least one anchor is fixedly arranged on the back of the fixing plate. For example, the anchor is a T-bolt, one end of the screw of the T-bolt is the head, and the other end is welded and fixed to the back of the fixing plate or the back of the main part of the HALFEN rail.

[0008] The front of the main part of the HALFEN rail and the front of the fixing plate are preferably in contact with the inner wall of the template. Specifically: the thickness of the two wing plates is consistent, the distance between the inner corner lines corresponding to the inner corners of the two hanging platforms and the front of the fixing plate is consistent, and the thickness and distance are equal.

[0009] In order to ensure that the fixing plate can be firmly fixed to the inner wall of the template, further: at least two mounting holes are provided on both sides of the notch of the fixing plate, and at least one mounting hole is provided at the bottom of the notch.

[0010] In order to prevent the main part of the HALFEN CAGE RAIL from being pulled out after being inserted into the installation slot, a limiting structure is further provided between the HALFEN CAGE RAIL and the fixing plate to prevent the main part of the HALFEN CAGE RAIL from sliding out of the installation slot. For example, the L-shaped hanging platform is provided with a threaded hole, one end of the threaded hole is located on the side corresponding to the back of the fixing plate, and the other end is connected to the installation slot, and an adapted tightening screw is arranged in the threaded hole.

[0011] Since the HALFEN rail and the fixing plate will eventually be embedded in reinforced concrete, in order to ensure the material strength of the HALFEN rail and the fixing plate, further: the HALFEN rail and the fixing plate are both made of metal, the main body of the HALFEN rail is an integral part of the wing plate, and the plate body of the fixing plate is an integral part of the hanging platform.

[0012] Generally, HALFEN rails and fixing plates are made of steel. In order to prevent HALFEN rails and fixing plates from rusting, HALFEN rails and fixing plates are made of hot-dip galvanized steel.

[0013] The utility model has the following beneficial effects: screws or bolts are passed through the mounting holes of the fixing plate to preliminarily mount the fixing plate on the inner wall of the template, the notch of the fixing plate opens upward, and then the main part of the HALFEN rail is inserted into the mounting slot from top to bottom, and the screws or bolts are adjusted so that the front of the main part of the HALFEN rail fits tightly with the template, thus completing the installation of the HALFEN rail embedded assembly on the inner wall of the template. Since the smaller fixing plate is installed first, rather than directly installing the longer HALFEN rail, it is convenient to position the fixing plate, thereby ensuring the accuracy of the installation position of the HALFEN rail. The two wing plates of the HALFEN rail are clamped by the two hanging platforms of the fixing plate, and the HALFEN rail cannot move in the width direction of the slot, and the bottom of the notch of the fixing plate can prevent the HALFEN rail from falling, so the HALFEN rail can be firmly fixed to the template. By adjusting the screws or bolts, the two hanging platforms of the fixing plate press the two wing plates against the inner wall of the template, so that the front of the main part of the HALFEN rail is kept in close contact with the template, thereby avoiding the appearance of a gap between the front of the main part of the HALFEN rail and the template. The fixing plate is fixed to the inner wall of the formwork by multiple screws or bolts. The fixing plate is highly stable, and the impact and vibration of the poured concrete will not change the position of the fixing plate and the HALFEN rail. The HALFEN rail and the fixing plate are both poured in the concrete. The fixing plate can support the HALFEN rail and improve its bearing capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 As shown, the pre-embedded assembly of the Hafen rail of the utility model comprises a Hafen rail 1 and a fixing plate 2. The fixing plate 2 is used to be directly fixed to the inner wall of the template. The template is arranged vertically, and a mounting groove is formed between the fixing plate 2 and the inner wall of the template. The Hafen rail 1 is directly inserted vertically downward into the mounting groove to achieve the purpose of fixing the Hafen rail 1 to the inner wall of the template. The mounting groove and the Hafen rail 1 are adapted to each other, and the Hafen rail 1 and the template can maintain a close fit.

[0019] The HALFEN rail 1 comprises a main body 11 and an anchor 12. The front of the main body 11 is provided with a slot with closed ends. At least two anchors 12 are fixed to the back of the main body 11. The anchors 12 are arranged at intervals along the length direction of the main body 11. The anchors 12 are used to anchor the main body 11 in concrete. The length direction of the anchors 12 is preferably perpendicular to the length direction of the main body 11. For example, the anchor 12 is a T-bolt. One end of the screw of the T-bolt is the head, and the other end is welded and fixed to the back of the main body 11. The main body 11 of the HALFEN rail 1 is C-shaped in its cross section. The main body 11 is provided with wing plates 13 on both sides along the length direction of the slot. The wing plates 13 can be fixedly connected to the main body 11, or the wing plates 13 and the main body 11 are integral. Since the HALFEN rail 1 will eventually be embedded in reinforced concrete, in order to ensure the material strength of the HALFEN rail 1, the HALFEN rail 1 is made of metal, and the main body 11 of the HALFEN rail 1 and the wing plates 13 are integral. Generally, the HALFEN rail 1 is made of steel. To prevent the HALFEN rail 1 from rusting, the HALFEN rail 1 is made of hot-dip galvanized steel. The sides of the two wing plates 13 facing away from the anchor 12 are flush with the front of the main body 11, that is, the sides of the two wing plates 13 facing away from the anchor 12 are in the same plane as the front of the main body 11, so as to ensure that the HALFEN rail 1 and the template can fit tightly.

[0020] The two opposite surfaces of the fixing plate 2 are the front and back surfaces respectively, and at least two through mounting holes 21 are provided between the front and back surfaces. Each mounting hole 21 is provided with a matching screw or bolt. The screw or bolt passes through the mounting hole 21 of the fixing plate 2 and is then fixed to the template. The fixing plate 2 can be fixedly installed on the inner wall of the template. In order to ensure the strength of the screws and bolts, the screws are preferably high-strength screws, or the bolts are preferably high-strength bolts. The fixing plate 2 has a U-shaped notch 22, and the fixing plate 2 is U-shaped as a whole. In order to ensure that the fixing plate 2 can be firmly fixed to the inner wall of the template, at least two mounting holes 21 are provided on both sides of the notch 22 of the fixing plate 2, and at least one mounting hole 21 is provided at the bottom of the notch 22. Figure 2As shown, the two sides of the notch 22 of the fixed plate 2 are parallel to each other, and L-shaped hanging platforms 23 are respectively provided on both sides of the notch 22, that is, the hanging platforms 23 are L-shaped in their cross sections, and the length directions of the two hanging platforms 23 are parallel to each other, and the two hanging platforms 23 both protrude toward the back of the fixed plate 2. Since the fixed plate 2 will eventually be embedded in reinforced concrete, in order to ensure the material strength of the fixed plate 2, the fixed plate 2 is made of metal, and the plate body of the fixed plate 2 and the hanging platforms 23 are a whole. Generally, the fixed plate 2 is a steel part. In order to prevent the fixed plate 2 from being rusted, the fixed plate 2 is a hot-dip galvanized steel part. An installation groove adapted to the Hafen rail 1 is formed between the two hanging platforms 23 of the fixed plate 2. The depth of the hanging platform 23 does not exceed the thickness of the wing plate 13 of the Halfen rail 1, so that the Halfen rail 1 can not move in a direction perpendicular to the template; the distance between the two hanging platforms 23 is consistent with the distance between the outer edges of the two wing plates 13 of the Halfen rail 1, so that the Halfen rail 1 can not move in a direction parallel to the plane corresponding to the template and perpendicular to the length direction of the slot. The two wing plates 13 of the Halfen rail 1 are preferably the same. The front of the main part 11 of the Halfen rail 1 and the front of the fixing plate 2 are preferably in contact with the inner wall of the template, so that the contact area between the embedded components of the Halfen rail and the template can be increased. Therefore, the thickness of the two wing plates 13 is consistent, and the inner angle lines corresponding to the inner angles of the two hanging platforms 23 are consistent with the distance from the front of the fixing plate 2, and the thickness and distance are equal. The fixing plate 2 will eventually be embedded in the reinforced concrete. In order to improve the bonding strength between the fixing plate 2 and the concrete, at least one anchor 12 can also be fixed on the back of the fixing plate 2. This solution is not shown in the attached drawings. The anchor 12 on the back of the fixing plate 2 can be the same as the anchor 12 on the back of the main part 11 of the HALFEN rail 1. For example, the anchor 12 on the back of the fixing plate 2 is a T-bolt, one end of the screw of the T-bolt is the head, and the other end is welded and fixed to the back of the fixing plate 2.

[0021] The Hafen rail 1 is generally installed vertically, that is, the length direction of the main part 11 of the Hafen rail 1 is arranged vertically, so after the main part 11 of the Hafen rail 1 is inserted into the installation slot, the fixing plate 2 can keep the Hafen rail 1 fixed. In order to prevent the main part 11 of the Hafen rail 1 from being pulled out after being inserted into the installation slot, a limiting structure can be provided between the Hafen rail 1 and the fixing plate 2 to prevent the main part 11 of the Hafen rail 1 from sliding out of the installation slot. For example, the L-shaped hanging platform 23 is provided with a threaded hole, one end of the threaded hole is located on the side corresponding to the back of the fixing plate 2, and the other end is connected to the installation slot. An adapted tightening screw is arranged in the threaded hole. After the main part 11 of the Hafen rail 1 is inserted into the installation slot, the tightening screw is tightened, and the tightening screw tightens the wing plate 13. The tightening screw can also improve the bonding strength between the fixing plate 2 and the concrete, and play an equivalent role to setting the anchor 12 on the back of the fixing plate 2. For another example, mutually matching protrusions and grooves are provided between the hanging platform 23 and the wing plate 13 . After the Hafen rail 1 is inserted to the bottom, the protrusions are buckled into the grooves, thereby achieving locking between the hanging platform 23 and the wing plate 13 .

[0022] The utility model of the pre-embedded Hafen rail assembly is a small component with fewer structural parts and a simple structure, so it can be mass-produced with relatively low production costs. The Hafen rail 1 and the fixing plate 2 are both metal parts that are not easy to deform, have reliable quality, require very few casting processes during manufacturing, and the precision control also meets professional requirements. The pre-embedded Hafen rail assembly is easy to install and can effectively fix the Hafen rail 1, preventing the Hafen rail 1 from changing position due to the impact of external forces when pouring concrete, and avoiding the problem of being filled and buried by concrete and foreign objects entering the slot.
