Description
Technical field
The utility model relates to a kind of sash weights for precise measurement pile bottom sediment thickness, belong to building construction measurement tool
Technical field.
Background technique
Sediment, which refers to, to be precipitated during drilling and borehole cleaning or collapse hole leaves, and the sediment that do not taken away by circulating mud.Root
It according to " technical code for building pile foundation " (JGJ 94-2008), drills and reaches projected depth, before concrete perfusion, bottom hole sediment is thick
Degree index should be met the following requirements: hold type stake for end, sediment thickness should not exceed 50mm.
There is following several the method for traditional control sediment thickness on construction site: the hole depth measured twice one is certain it
Difference, another is that stylus surveys cake method, besides completely with construction experience.Above method error is big, and sediment thickness is excessive
It will affect pile quality, pile integrity caused to detect unqualified, structure sediment and other issues.
Utility model content
The purpose of this utility model is to provide it is a kind of it is easy to operate, can be improved working efficiency for precise measurement stake bottom
The sash weight of sediment thickness, to solve the problems mentioned in the above background technology.
The technical solution of the utility model includes: a kind of sash weight for precise measurement pile bottom sediment thickness, including outer cylinder and
The weight for being arranged in outer cylinder and being slidably matched with outer cylinder, the weight include cylindrical body and are respectively fixedly connected in cylindrical body
The hanging ring and hammer tip of upper and lower ends, hanging ring are stretched out at the top of outer cylinder and are connect with lifting rope；The outer cylinder includes cylinder and connection
Disk in cylinder lower end is marked with graduation mark in the outer wall of cylinder, limiting device is provided between weight and outer cylinder.
Further, the limiting device includes one group of card slot being arranged on the cylinder and is equably provided with cylinder side
Cylinder is divided into the bar shaped side wall of one group of equivalent width by the strip groove on wall, strip groove, between adjacent bar shaped side wall
Top is fixedly connected with magnet mounting rack, and magnet is fixedly mounted on magnet mounting rack, between adjacent bar shaped side wall under
Portion is fixed with fixing axle, and spacing card is rotatably connected in fixing axle, and magnet is adsorbed and be close in spacing card upper end by magnet,
Its lower end is stuck on card slot.
Further, the tooth of the card slot is equidistantly 3mm.
Further, arc block, and the radian of arc block and cylinder radian one are fixedly connected between the bar shaped side wall
It causes.
Further, the tick marks are on bar shaped side wall.
Due to the adoption of the above technical scheme, utility model has the advantages that
1, the outer tube structure of the utility model is small from heavy and light, buoyancy, and the strip groove opened up on outer cylinder is conducive in subtracting
Few resistance, reduces air pressure, so that the smooth free-falling of sash weight；
2, the bottom of the outer cylinder of the utility model has a disk, can only fall on sediment top surface down, and entirely to hang
Hammer keeps vertical, will not tilt the accuracy for guaranteeing measurement on one side；
3, the weight self weight of the utility model is heavier, can continue across when outer cylinder disk is parked in sediment surface and arrive under sediment
The falling head of stake bed rock level, opposite outer cylinder is the thickness of sediment；
4, contain magnet on the inside of the fixing groove of the utility model, lifting rope hangs weight and keeps during slowly declining, magnet
Resistance and the outer cylinder self weight of offer are greater than the buoyancy of outer cylinder, guarantee that relative displacement cannot occur for outer cylinder and weight, it is ensured that measurement is just
Beginning to read is zero；
5, the card slot tooth horizontal segment of the utility model can generate braking effect, tighten lifting rope, in weight uphill process, card slot
Tooth horizontal segment, which resists limiting card lower end, translates into it under in the card slot of lower part, guarantees that final reading is constant when sash weight is withdrawn.

Specific embodiment
It is right with reference to the accompanying drawings and examples in order to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiments of the present invention: structural schematic diagram such as Fig. 1~3 of the sash weight for precise measurement pile bottom sediment thickness
Shown, including outer cylinder 3 and the weight 2 for being arranged in outer cylinder 3 and being slidably matched with outer cylinder 3, the weight 2 includes cylindrical body 6
And be respectively fixedly connected with hanging ring 5 and hammer tip 7 in 6 upper and lower ends of cylindrical body, hanging ring 5 stretched out at the top of outer cylinder 3 and with lifting rope 1
Connection；The diameter of the cylindrical body 6 is 60mm, high 100mm, the high 80mm of hammer tip 7, because needing when sediment thickness is more than 50mm
Again borehole cleaning does not have to measure specific value, so the high 50mm of needle point of setting hammer tip 7；The outer cylinder 3 includes cylinder 15 and connects
The disk 16 in 15 lower end of cylinder is connect, graduation mark 8 is marked in the outer wall of cylinder 15, is provided between weight 2 and outer cylinder 3
Limiting device 9.The limiting device 9 includes one group of card slot 10 being arranged on cylindrical body 6 and is equably provided with cylinder 15
Strip groove 4 on side wall, the tooth of the card slot 10 are equidistantly 3mm, and cylinder 15 is divided into one group of equivalent width by strip groove 4
Bar shaped side wall 18, the top between adjacent bar shaped side wall 18 are fixedly connected with magnet mounting rack 12, and magnet 11 is fixedly mounted
On magnet mounting rack 12, the lower part between adjacent bar shaped side wall 18 is fixed with fixing axle 14, rotates in fixing axle 14
It is connected with spacing card 13, magnet 11 is adsorbed and be close in 13 upper end of spacing card by magnet 11, and lower end is stuck on card slot 10.Institute
It states and is fixedly connected with arc block 17 between bar shaped side wall 18, and the radian of arc block 17 is consistent with 15 radian of cylinder.The scale
Line 8 marks on bar shaped side wall 18.
Fig. 4 is participated in, working principle of the utility model is:
Before process one, drilling reach projected depth and concrete perfusion, portable lifting rope 1 is transferred in sash weight to stake holes, is protected
It holds sash weight and slowly falls close to pile center, pay attention to avoiding sash weight from encountering reinforcing bar and causing limit film to move up and read.
After falling on sediment top surface under process two, sash weight, disk (16) falls in sediment top surface and keeps stablizing, and weight (2) is certainly
Continue to decline under recast, until hammer tip 7 reaches stake bed rock layer top surface, reads, because of sediment surface irregularity, should slightly mention
It rises, decentralization sash weight repeatedly measures.
Process three, tightening lifting rope 1, up slowly propose sash weight, read on the line that calibrates, and need when more than 50mm again clear
Hole.
