Abstract

The utility model belongs to the building engineering field, concretely relates to a fixture for fixing buried bolt in advance. A fixture for fixing buried bolt in advance, includes four fretwork rectangular plates that the structure is the same, the inside of fretwork rectangular plate is equipped with rectangle through groove, rectangle through groove's internal diameter and in advance buried bolt's external diameter be clearance fit, two -layer and be the groined type and arrange about four fretwork rectangular plates divide into, two fretwork rectangular plates of contact pass through anchor clamps fixed connection each other. The utility model discloses a fixture for fixing buried bolt in advance has following beneficial effect: (1 ), simplify the welding job that requires special skills for twisting the screw, the unskilled labor is per capita operatable, the financial resources of using manpower sparingly, (2 ), making up many bolts become wholly, making bolt relative pitch fixed, make it change in fixed and improvement precision, these working energys go on in advance moreover, make the work of crucial circuit become non - crucial circuit, have shortened the time limit for a project, (3 ), but reuse, save material, engineering volume effect big more is obvious more.

Description

A kind of jig for fixing pre-embedded bolt
Technical field
The utility model belongs to building engineering field, is specifically related to a kind of jig for fixing pre-embedded bolt.
Background technology
The structural shape majority of industrial premises is bottom concrete independent column foundation, and top is steel work.Steel structure column and concrete foundation short column adopt bolt to link, and this just needs the pre-embedded anchoring bolts when constructing concrete foundation, for connecting top steel column.The pre-embedded bolt amount of general relatively large industrial premises is all larger, and have higher required precision, need professional's operation of certain level, also want surveyor's transit and level gauge to coordinate, efficiency is very low, thus bolt fixedly become the key affecting duration and quality.
At present, the fixing of stone bolt is all after foundation columns reinforcing bar, template construction complete, and under the cooperation of survey crew, respectively the spot welding of every root bolt is fixed on foundation columns by electric welder, and period need be added certain bar dowel and be reinforced.There is following shortcoming in it: 1, tie up muscle, formwork carries out weld job inconvenient operation in post after completing, the foundation columns that especially some sections are less can be more difficult, and when fixing next root bolt, be easy to the bolt that disturbance was fixed in the past; 2, because set bolt generally belongs to critical circuits operation, for the reduction of erection time then needs to drop into more personnel, but also be the special operation workers having higher technical level, duration, expense can not be taken into account; 3, carrying out weld job to bolt easily causes bolt to burn, and affects bolt strength, as being welded on the main muscle of foundation columns also can affect main muscle stressed.
Utility model content
Utility model object: the utility model makes improvement for above-mentioned prior art Problems existing, namely the utility model discloses a kind of jig for fixing pre-embedded bolt.
Technical scheme: a kind of jig for fixing pre-embedded bolt, comprise the hollow out rectangular slab that four structures are identical, the inside of hollow out rectangular slab is provided with rectangular through slot, the internal diameter of rectangular through slot and the external diameter of pre-embedded bolt are matched in clearance, four hollow out rectangular slabs are divided into two-layer up and down and arrange in groined type, and two the hollow out rectangular slabs contacted with each other are fixedly connected with by fixture.
Further, two the hollow out rectangular slabs contacted with each other are fixedly connected with by three fixtures in outside.
Further, the thickness of the internal diameter of the U-lag of fixture and the lateral wall of hollow out rectangular slab is matched in clearance.
Beneficial effect: disclosed in the utility model, a kind of jig for fixing pre-embedded bolt has following beneficial effect:
(1), welding job that requires special skills be reduced to the turn of the screw, unskilled labor can operate per capita, saves manpower financial capacity;
(2), plurality of bolts be combined into entirety, bolt relative spacing is fixed, make it be easier to fixing and improve precision, and these work can be carried out in advance, make the work of critical circuits become non-key circuit, shorten the duration;
(3), can reuse, save material, the larger effect of engineering quantity is more obvious.

The structural representation of Fig. 1 a kind of jig for fixing pre-embedded bolt disclosed in the utility model;
Fig. 2 is the structural representation of fixture
Wherein:
1-fixture 2-hollow out rectangular slab
3-bolt 11-screw
Detailed description of the invention:
Below detailed description of the invention of the present utility model is described in detail.
As depicted in figs. 1 and 2, a kind of jig for fixing pre-embedded bolt, comprise the hollow out rectangular slab 2 that four structures are identical, the inside of hollow out rectangular slab 2 is provided with rectangular through slot, the internal diameter of rectangular through slot and the external diameter of pre-embedded bolt 3 are matched in clearance, four hollow out rectangular slabs 2 are divided into two-layer up and down and arrange in groined type, and two the hollow out rectangular slabs 2 contacted with each other are fixedly connected with by fixture 11.The lateral wall clamping of the U-lag on the top of fixture 1 and the hollow out rectangular slab 2 on upper strata, the bottom of fixture 1 contacts with the hollow out rectangular slab 2 of lower floor and passes through affixed two the hollow out rectangular slabs 2 contacted with each other of bolt through screw 11.
Further, two the hollow out rectangular slabs 2 contacted with each other are fixedly connected with by three fixtures 1 in outside.
Further, the thickness of the internal diameter of the U-lag of fixture 1 and the lateral wall of hollow out rectangular slab 2 is matched in clearance.
A kind of jig for fixing pre-embedded bolt disclosed in the present application adopts four pieces of hollow out rectangular slabs 2, will pre-buried plurality of bolts 3 be needed to be combined into an entirety, thus the relative spacing of each bolts 3 is fixed.Like this after foundation columns formwork completes, just bolt 3 assembly made in advance can be installed as a large embedded part, be equivalent to decrease the quantity needing pre-embedded bolt 3.And bolt 3 assembly can be fixed on above basic short column by fixture 1 fast, easily complete the burying work beforehand of bolt 3.
Disclosed in present patent application, a kind of jig for fixing pre-embedded bolt is simplified, and plurality of bolts 3 embedded part is combined into a large embedded part, and these work can be carried out in advance, do not take critical circuits activity time.In the middle of steel plate strip, the slidable adjustment function of hollow slots, makes this patent be applicable to multiple bolt 3 spacing and column cross-section size.
Above embodiment of the present utility model is elaborated.But the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
