Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an anti-floating anchor rod positioning and fixing device. Background Art

[0002] Anti-floating anchor rods are one of the anti-floating measures for underground structures in construction projects. They are anchor rods installed in the sand and gravel layer to resist the floating force of groundwater on the building. The rod body of the anti-floating anchor rod is generally threaded steel bars or steel strands. During the construction of anti-floating anchor rods, multiple anchor rods (usually 3) are usually spot welded into an anchor rod bundle as an integral component and placed in the drilled anchor rod hole before grouting.

[0003] Since the diameter of the anti-floating anchor hole is larger than that of the anchor bundle, the anchor bundle must be inserted into the hole to ensure that its axis is in the center of the hole, and the angle and stability of the hole must be guaranteed. However, since the anti-floating anchor is generally long, manual operation cannot ensure the angle and stability of the hole, resulting in a large deviation of the center position of the anti-floating anchor in the hole during grouting, thus affecting the construction quality of the anti-floating anchor. In addition, when the material of the anti-floating anchor is steel strand, its positioning and fixation are more difficult because welding of the steel strand is not allowed. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide an anti-floating anchor positioning and fixing device, which adopts a mechanical snap-fit ​​fixing method. While effectively ensuring the accurate relative position of the anchor reinforcement, it can ensure that the position of the anchor bundle is located in the center of the anchor hole, thereby ensuring the construction quality of the anti-floating anchor, and can be suitable for the positioning and fixing of the anchor reinforcement as a steel strand.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Furthermore, the fixing sleeve includes a pair of arc panels, the opposite ends of the pair of arc panels are hinged by a hinge shaft, and the other opposite ends are each provided with a positioning plate, the fixing plate is sandwiched between the pair of positioning plates, and fasteners are provided to detachably connect the fixing plates.

[0008] Furthermore, the inner circumference of the fixing sleeve has a plurality of arc-shaped concave surfaces, and one side of the outer circumference of each anchor bar contacts with the corresponding arc-shaped concave surface, and the other side contacts with the outer circumference of the positioning rod.

[0009] Furthermore, the cross section of the arc-shaped concave surface is semicircular.

[0010] Furthermore, the fixing plate is provided with a first through hole, and a pair of the positioning plates opposite to the hinge shaft are both provided with a second through hole which penetrates the first through hole, and the fastener is penetrated in the first through hole and the second through hole.

[0011] Furthermore, the fastener is a bolt.

[0012] Furthermore, a plurality of fixing sleeves are arranged at intervals in the axial direction of the anchor bar, and each fixing sleeve clamps the fixing plate and is connected to the positioning rod.

[0013] Furthermore, one of the second through holes of the pair of positioning plates opposite to the hinge axis is a threaded hole.

[0014] The utility model adopts the above technical solution, which has the following advantages and effects:

[0015] The utility model provides an anti-floating anchor rod positioning and fixing device, which adopts a fixing sleeve and a positioning rod to clamp and fix the anti-floating anchor rod sleeve in the anchor rod hole through mechanical positioning and snap-fit ​​clamping. The positioning and fixing device can be arbitrarily adjusted along the axial position of the anti-floating anchor rod, which solves the problem of accurate positioning of the anti-floating anchor rod and changes the welding positioning method used in traditional construction. At the same time, it is also suitable for situations where welding is not allowed when the anchor rod reinforcement is a steel strand. The utility model is simple to manufacture, easy to use, and can be reused, which saves costs and is suitable for large-scale promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 3 The utility model provides an anti-floating anchor rod positioning and fixing device, comprising a positioning rod 1 and a snap-fitting fixing sleeve 3 which is sleeved on the outer periphery of the positioning rod 1, the positioning rod 1 and the fixing sleeve 3 are nested in the anchor rod hole 5, a fixing plate 2 is arranged on the outer periphery of the positioning rod 1, one end of the fixing plate 2 is detachably connected to the fixing sleeve 3, a plurality of positioning plates 4 are arranged at intervals on the outer periphery of the fixing sleeve 3, one end of the positioning plate 4 extending to the inner periphery of the anchor rod hole 5 is spaced from the inner periphery of the anchor rod hole 5, a plurality of anchor rod ribs 6 are arranged between the positioning rod 1 and the fixing sleeve 3, and the anchor rod ribs 6 are spaced between the positioning rod 1 and the fixing sleeve 3 and are clamped by the fixing sleeve 3 and the positioning rod 1.

[0023] Specifically, the positioning rod 1, the fixing sleeve 3 and the anchor hole 5 are coaxially sleeved inside and outside in sequence, and the snap-fit ​​fixing sleeve 3 can be opened to sleeve the positioning rod 1 and the anchor bar 6 and then snap-fit ​​to fix the anchor bar 6 between the fixing sleeve 3 and the positioning rod 1. The outer end of the positioning plate 4 on the outer periphery of the fixing sleeve 3 is 2-3mm away from the inner periphery of the anchor hole 5, so that the anchor bundle can be normally inserted into the anchor hole 5 after being fixed. The positioning plates 4 are distributed at intervals on the outer periphery of the fixing sleeve 3 and are also used to determine whether the fixing sleeve 3 and the positioning rod 1 are in the center of the anchor hole 5.

[0024] Furthermore, the fixing sleeve 3 includes a pair of hinged arc panels, the opposite ends of the pair of arc panels are hinged by a hinge axis, and a positioning plate 4 is provided at the other end of the pair of arc panels opposite to the hinge axis 8. A fixing plate 2 is sandwiched between the pair of positioning plates 4 opposite to the hinge axis 8, and fasteners are provided to detachably connect the fixing plate 2.

[0025] Specifically, one end of a pair of curved panels is hinged by a hinge shaft 8, and a positioning plate 4 is welded to the outer peripheral edge of the other end. After a pair of curved panels are buckled by the positioning plates 4 at the end, there is a gap between the positioning plates 4 at the end, and the gap is used to nest the fixing plate 2. In order to facilitate the fixing and positioning of the anchor bar 6, the curved panel and the outer periphery of the anchor bar 6 can form an axial contact fixation. In the utility model, a pair of curved panels are hinged to form a "pin"-shaped structure, and three anchor bars 6 can be fixed inside.

[0026] Furthermore, the inner circumference of the fixing sleeve 3 has a plurality of arc-shaped concave surfaces, and one side of the outer circumference of each anchor bar 6 contacts the corresponding arc-shaped concave surface, and the other side contacts the outer circumference of the positioning rod 1 .

[0027] Specifically, a large gap space is formed between the arc-shaped concave surface and the positioning rod 1, which is convenient for placing the anchor bar 6, and at the same time, the fixing sleeve 3 is relatively compact and convenient for being accommodated between the positioning rod 1 and the anchor hole 5. In the utility model, the fixing sleeve 3 is hinged by a pair of arc-shaped panels and has three arc-shaped concave surfaces. The arc-shaped concave surfaces are evenly arranged on a pair of arc-shaped panels after buckling. The center of one of the arc-shaped concave surfaces is the hinge axis. The anchor bar 6 is respectively embedded in the three arc-shaped concave surfaces. After the pair of arc-shaped panels are buckled, the inner periphery of the arc-shaped concave surface and the outer periphery of the positioning rod 1 respectively clamp and fix the anchor bar 6.

[0028] Furthermore, the cross section of the arc-shaped concave surface is semicircular. The arc-shaped concave surface of the semicircular structure can better nest the anchor bar 6 while making the structure of the fixing sleeve 3 compact and facilitating the one-step molding process of the fixing sleeve 3.

The fastener fastens the fixing sleeve 3 while fixing the positioning plate 4, so that the fixing sleeve 3 and the positioning rod 1 clamp and fix the anchor bar 6.

[0030] Furthermore, the fastener is a bolt 7. The bolt 7 passes through the first through hole 21 and the second through hole and is locked by a nut.

[0031] Of course, the second through hole on the positioning plate 4 on one side can be a threaded hole, in which case a nut is not required. The bolt 7 and the threaded hole are threadedly matched to achieve locking.

[0032] Furthermore, a plurality of fixing sleeves 3 are arranged at intervals in the axial direction of the anchor bar 6, and each fixing sleeve 3 is clamped with a fixing plate 2 and connected to the positioning rod 1. The fixing sleeves 3 are arranged at intervals in sequence on the axial periphery of the anchor bar 6 forming the anchor bar bundle, and the fixing sleeves 3 are connected to the positioning rod 1 through the fixing plate 2, and the positioning rod 1 is located at the center of the anchor bar bundle.

[0033] When the utility model is manufactured, the positioning rod 1 is a long outer diameter of 20mm and a length of 100m.

[0034] m steel bar, the fixed plate and the fixed plate 2 are 5mm thick and 30mm wide steel plates, one end of the fixed plate 2 is welded to the center periphery of the positioning rod 1, and the fixed sleeve 3 is made of 5mm thick and 30mm wide steel plate. After forging an arc-shaped concave surface, it is divided into two halves and hinged. A positioning plate 4 is welded to each end at the same time, and holes are drilled on the positioning plate 4 and the fixed plate 2.

[0035] like Figure 4As shown. When the utility model is used, a group of anchor bars 6 (usually 3) in each anti-floating anchor are aligned and placed on a flat ground, and then the installation position lines of the fixing sleeve 3 and the positioning rod 1 are marked on the anchor bars 6 at intervals of 2m, and then the positioning rod 1 is first placed in the middle of the inner circumference of each anchor bar 6 at each position line, and the fixing plate 2 extends out of the outer circumference of the anchor bar 6, and finally the fixing sleeve 3 is put on the corresponding position of the outer circumference of the anchor bar 6, and finally the bolt 7 is passed through the positioning plate 4 and the fixing plate 2 and tightened. After all the anchor bars 6 of each anti-floating anchor are fixed, they are placed in the drilled anchor hole 5 and then post-grouting is performed.
