Abstract
A kind of pre-buried fixing device of strip footing crab-bolt group, belongs to the anchor bolt preburied technical field of construction of architectural engineering.Including crab-bolt, nut, bracket, lumps of wood column, template, lumps of wood crossbeam, Screw arbor with nut at both-ends, to draw nut, angle steel cornerite, wood screw, U-shaped card；Wherein, two brackets (3) are directly fixedly connected by Screw arbor with nut at both-ends (7) with to drawing nut (8)；Lumps of wood column (4) is fixedly connected with template (5) using steel nail；Lumps of wood crossbeam (6) is fixedly connected with lumps of wood column (4) by angle steel cornerite (9) and wood screw (10), and bracket (3) is fixedly connected with lumps of wood crossbeam (6) by U-shaped card (11) and wood screw (10).Advantage is, the device independent levitation in foundation platform top, will not because vibrate or the displacement of reinforcing bar to crab-bolt caused by offset, positioning precision is higher, meets the pre-buried required precision of strip footing crab-bolt group.
Description
Technical field
The utility model belongs to the anchor bolt preburied technical field of construction of architectural engineering, in particular, provides a kind of strip footing anchor
The pre-buried fixing device of bolt group, suitable for the pre-buried of super long type strip footing crab-bolt group.
Background technology
At present, it is varied in the pre-buried form of architectural engineering foundation anchor bolt, but mostly rectangle isolated footing and flange-type base
Plinth, and foundation anchor bolt quantity is few, diameter.
Routine it is anchor bolt preburied in, more using fixing chuck plate is increased in basis, clamp is poured into mixed together with crab-bolt
In solidifying soil, this positioner can not fundamentally ensure being accurately positioned for crab-bolt.Because it is together with bar connecting, pouring
In concrete and process of vibrating, the flexible of reinforcing bar often drives crab-bolt displacement, can not guarantee the installation accuracy of crab-bolt, especially anchor
Bolt group.Anchor bolt preburied for strip footing in order to solve the above problems, it is pre-buried solid that my unit designs a kind of strip footing crab-bolt group
Determine device, form bracing system of its independent levitation before basis pours, it is difficult can to solve the pre-buried precision of strip footing crab-bolt group
Topic.
The content of the invention
The purpose of this utility model is to provide a kind of pre-buried fixing device of strip footing crab-bolt group.Solves current crab-bolt group
It is pre-buried to be unable to reach installation accuracy, the larger problem of deviation.By the application of the device, the pre-buried precision of crab-bolt group can reach peace
The effect of punching rate 100% is filled, and can be reused.
The utility model includes：Crab-bolt 1, nut 2, bracket 3, lumps of wood column 4, template 5, lumps of wood crossbeam 6, Screw arbor with nut at both-ends 7,
To drawing nut 8, angle steel cornerite 9, wood screw 10, U-shaped card 11.Wherein, bracket 3 is made using square steel tube, and drawing is pressed on bracket 3
Upper crab-bolt spacing drilling, and in side face drilling split bolt hole；Crab-bolt is fixed using Frame for supporting parallel pipes, passes through two holes above and below steel pipe
Positioning, can ensure crab-bolt perpendicularity.Two brackets are fixed by Screw arbor with nut at both-ends, crab-bolt axis spacing can be ensured.
Two brackets 3 are directly fixedly connected by Screw arbor with nut at both-ends 7 with to drawing nut 8；Lumps of wood column 4 uses steel nail with template 5
It is fixedly connected；Lumps of wood crossbeam 6 is fixedly connected with lumps of wood column 4 by angle steel cornerite 9 and wood screw 10, by adjusting lumps of wood crossbeam
6 height, determine crab-bolt screw thread exposed length；By adjusting the height of lumps of wood crossbeam 6, regulation determines that crab-bolt screw thread exposes length
Degree；Pass through U-shaped card mounting bracket, it is ensured that bracket is fixed, ensures bracket intensity.Bracket 3 passes through U-shaped card with lumps of wood crossbeam 6
11 are fixedly connected with wood screw 10.
This crab-bolt group fixing device utilizes lumps of wood column 4, lumps of wood crossbeam 6, U-shaped card, angle using the existing template system in basis
Ladle angle 9, bracket 3 and Screw arbor with nut at both-ends etc. are bracket-shaped integral by crab-bolt, come and go repetition measurement before pouring, pouring rear error change can
For 0mm- ± 1mm, the effect of punching rate 100% can be achieved.
The utility model has the advantage of：The pre-buried fixing device of crab-bolt group can be general on the basis of different type, bracket
Adjust and simple for production, different size can be selected according to crab-bolt diameter, so as to meet various anchor bolt preburied requirements；Bracket is adopted
With steel pipe manufacturing, crab-bolt is positioned by two holes above and below steel pipe, can be good at controlling crab-bolt perpendicularity；The device independent levitation
In foundation platform top, will not because vibrate or the displacement of reinforcing bar to crab-bolt caused by offset, positioning precision is higher, meets strip footing
The pre-buried required precision of crab-bolt group.
Brief description of the drawings
Fig. 1 is axonometric drawing of the present utility model.
Fig. 2 is axonometric drawing A of the present utility model partial enlarged drawing.
Fig. 3 is left view of the present utility model.
In figure, crab-bolt 1, nut 2, bracket 3, lumps of wood column 4, template 5, lumps of wood crossbeam 6, Screw arbor with nut at both-ends 7, to draw nut 8,
Angle steel cornerite 9, wood screw 10, U-shaped card 11.
Embodiment
Fig. 1-3 is a kind of embodiment of the present utility model.
The utility model includes：Crab-bolt 1, nut 2, bracket 3, lumps of wood column 4, template 5, lumps of wood crossbeam 6, Screw arbor with nut at both-ends 7,
To drawing nut 8, angle steel cornerite 9, wood screw 10, U-shaped card 11.Wherein, bracket 3 uses steel pipe manufacturing, by drawing on bracket 3
Crab-bolt spacing drills, and in side face drilling split bolt hole；Two brackets 3 directly connect by Screw arbor with nut at both-ends 7 and to drawing nut 8 to fix
Connect；Lumps of wood column 4 is fixedly connected with template 5 using steel nail；Lumps of wood crossbeam 6 passes through angle steel cornerite 9 and wood screw with lumps of wood column 4
10 are fixedly connected, and by adjusting the height of lumps of wood crossbeam 6, determine crab-bolt screw thread exposed length；Bracket 3 passes through U with lumps of wood crossbeam 6
Shape card 11 is fixedly connected with wood screw 10.
The pre-buried fixing device of crab-bolt group when in use, using the existing template system in basis, utilizes lumps of wood column 4, the lumps of wood
