Abstract
The invention relates to a foundation bolt group fixing structure and a construction method thereof. The construction method comprises the steps of cutting a steel plate with similar size as a column foot plate; snapping bolt hole position lines on the steel plate, then drilling holes; penetrating bolts into the steel plate holes, temporarily fixing the upper parts of the bolts and the steel plate through nuts, and inserting the lower parts of the bolts into foundation reinforcement; after adjusting the position and the elevation of the steel plate according to a steel column axis position, tightening the nuts, and welding the lower parts of the bolts and the foundation reinforcement; casting independent foundation concrete; after concrete casting and before initial setting, retesting and adjusting bolt positions, bolt rod spacing, elevation, steel plate position and elevation; after the strength of the independent foundation concrete achieves 1.2mps, taking the steel plate and the nuts down, and reusing; enabling the steel column bolt holes to penetrate through reserved bolt rods, and fixing through the nuts. The foundation bolt group fixing structure and the construction method thereof provided by the invention overcome the defect that group foundation bolt positions are reserved inaccurately in steel structure construction, the convenience in construction is realized, the working efficiency is high, the installation cost is low, and the steel plate and the nuts can be recycled.
Description
Technical field
The present invention relates to the construction method of installation of foundation bolt, specifically a kind of foundation bolt fixed structure in groups and construction method thereof.
Background technology
In conventional steel structure construction, foundation bolt installation method is usually single bolt and isolated footing reinforcing bar binding or welds together, and this is it is difficult to ensure that the absolute position of bolt and absolute altitude, the bolt quality more Customers ' Legal Right of group.
Summary of the invention
Present invention seek to address that the problems referred to above that existing foundation bolt installation method exists, and a kind of foundation bolt fixed structure in groups and construction method thereof are provided.
The present invention solves its technical problem and the technical scheme is that
A kind of foundation bolt fixed structure in groups, including punched steel plate, foundation bolt, bolt hole it is provided with on punched steel plate, number and the position of bolt hole are determined by embedding anchor bolts position, foundation bolt upper end through bolt hole and is fixed with punched steel plate by nut, and foundation bolt lower end is to insert the connection end welded in reinforcement foundation and with reinforcement foundation.
Further, diameter of bolt hole is more than foundation bolt diameter 1mm.
The construction method of above-mentioned foundation bolt fixed structure in groups, is carried out in the steps below:
(1) one block of steel plate similar to heel slab size of cutting, ejects the position line of bolt hole according to drawing above；
(2) hole according to snap the line position with radial drill；
(3) being penetrated by foundation bolt in punched steel plate hole, foundation bolt is fixed by foundation bolt top nut with punched steel plate temporarily, and foundation bolt bottom is inserted in reinforcement foundation；
(4) the steel shaft line position theodolite first put well according to examination and level gauge adjust position and the absolute altitude of punched steel plate, after adjusting, by nut screwing clamping, are welded with reinforcement foundation foundation bolt bottom；
(5) isolated footing concrete is poured；
(6) concreting completes and before initial set, with theodolite and the position of level gauge repetition measurement foundation bolt, shank of bolt spacing, absolute altitude, the position of repetition measurement punched steel plate and absolute altitude, as being subjected to displacement, is adjusted；
(7), after independent concrete foundation intensity reaches 1.2mpa, punched steel plate is taken off with nut and reuses；
(8) when installing steel column, being penetrated by the bolt hole of steel column in reserved shank of bolt, nut is fixed.
Using the present invention of technique scheme, compared with prior art, it provides the benefit that:
Solving in Construction of Steel Structure foot bolt position in groups and reserve inaccurate shortcoming, and easy construction, working performance is high, and mounting cost is low, and steel plate and nut can be recycled, economical, last a long time.
Further, the preferred version of the present invention is:
In step (4), when shank of bolt has spacing with reinforcement foundation, choose two short reinforcing bar auxiliary bars and shank of bolt is welded together with reinforcement foundation.
In step (6), adjustment of displacement uses the hand hammer mode of rapping to carry out.

Detailed description of the invention
Below in conjunction with drawings and Examples in detail the present invention is described in detail, but the present embodiment does not constitute any restriction to the present invention.
See Fig. 1, Fig. 2, a kind of foundation bolt fixed structure in groups, it is made up of punched steel plate 1, foundation bolt 2 and nut, bolt hole 2 it is provided with on punched steel plate 1, number and the position of bolt hole 2 are determined by the pre-buried position of foundation bolt 3, foundation bolt 3 upper end is fixed through bolt hole 2 and by nut with punched steel plate 1, and foundation bolt 3 lower end is to insert the connection end welded in reinforcement foundation and with reinforcement foundation.
The construction method of above-mentioned foundation bolt fixed structure in groups, is carried out in the steps below:
(1) the rectangle steel plate of a piece of length and width respectively a, b of cutting is punched steel plate 1, and punched steel plate 1 is similar to heel slab size, ejects the position line (diameter of bolt hole 2 is than the foundation bolt 3 big 1mm of diameter) of bolt hole 2 on punched steel plate 1 according to drawing.
(2) 6 bolts hole 2 are got out with radial drill according to snap the line position.
(3) being penetrated by 6 bolts 3 in 6 bolts hole 2 of correspondence, foundation bolt 3 is fixed by foundation bolt 3 top nut with punched steel plate 1 temporarily, and foundation bolt 3 bottom is inserted in reinforcement foundation.
(4) the steel shaft line position theodolite first put well according to examination and level gauge adjust position and the absolute altitude of punched steel plate 1, after adjusting, by nut screwing clamping, foundation bolt 3 bottom and reinforcement foundation are welded (if shank of bolt and reinforcement foundation have spacing, can choose two short reinforcing bar auxiliary bars and shank of bolt and reinforcement foundation be welded together).
(5) pouring isolated footing concrete, during casting concrete, special messenger to be set keeps an eye on.
(6) concrete placings completes and before initial set, and with theodolite and the position of level gauge repetition measurement foundation bolt 3, shank of bolt spacing, absolute altitude, the position of repetition measurement steel plate 1 and absolute altitude, if it occur that displacement, available hand hammer is adjusted gently.
(7), after independent concrete foundation intensity reaches 1.2mpa, punched steel plate 1 can be taken off with nut and reuse.
(8) when installing steel column, being penetrated by the bolt hole of steel column in reserved shank of bolt, nut is fixed.
According to said method, i.e. realize foundation bolt of the present invention fixed structure in groups.
