Abstract
The invention aims at providing a method for installing oblique foundation bolts through a combined-type sizing stock to realize effects of high installation precision and fast installation speed. The method comprises the following steps of producing a positioning steel template, an oblique positioning rack and an embedded piece according to relative installation positions of the grouped foundation bolts, wherein the positioning steel template is provided with installation holes according to the design requirement on the relative positions of the foundation bolts, and an upper connection end of the oblique positioning rack is used for being connected with the positioning steel template; fixing the positioning steel template onto the oblique positioning rack; connecting the lower connection end of a horizontal positioning rack with the embedded piece, wherein the upper connection end of the horizontal positioning rack is used for being connected with the lower connection end of the oblique positioning rack; and fixedly connecting the horizontal positioning rack and the oblique positioning rack. All foundation bolts gradually penetrate through and are fixed inside the installation holes on the positioning steel template one by one. By adopting the method, the measuring workload can be greatly alleviated, the multi-times in-situ adjustment workload caused by the measurement can be alleviated, the installation precision is better guaranteed, and the overall working period of the project can be shortened.
Description
Technical field
The present invention relates to large-span steel project installation technique.
Background technology
In recent years, large span stadiums, conference and exhibition project are built like a raging fire, because of steel construction have lightweight, short construction period, moulding convenient, the advantage such as can to reuse, these long span buildings majorities adopt steel structural form.Because bearing the needs of horizontal loading, large-span steel arranges ramped abutment, each bearing by many obliquely foot bolt fix.Foot bolt installation method adopts sizing stock method traditionally, that is: install below extreme lower position 200mm place indwelling construction joint at bearing concreting to foundation bolt, and install four pieces of built-in fittings; At built-in fitting surface soldered sizing stock, look for position level face in stock upper end, then on position level face, weld location steel template, finally, bolt is penetrated location steel template, fixes bolt.But when adopting tradition sizing stock method to foot bolt obliquely, plane of orientation is that inclination is difficult to Measurement accuracy, because stock plan-position exists deviation when installing, then Different Plane position absolute altitude is different, and on-the-spot secondary cut looks for the inclined-plane degree of accuracy unreliable.Therefore adopt tradition sizing stock method to install foot bolt obliquely and there is surveying work amount greatly, locate inaccurate, installation progress is slow, has a strong impact on later process construction, thus affects the progress of whole engineering.Foundation bolt installation accuracy directly determines the installation accuracy of structural steelwork, additionally after foot bolt installation, carries out concrete building immediately, and therefore the installation of foundation bolt is in the critical process of construction substantially.Therefore ensure that the installation quality of foundation bolt is urgent problem in large-span steel engineering with improving installation progress.
Summary of the invention
The object of the present invention is to provide a kind of Combined type sizing stock that foot bolt method is obliquely installed, the effect that installation accuracy is high to reach, installation progress is fast.
Patent formula one: foot bolt method obliquely installed by the Combined type sizing stock in this programme, it is characterized in that comprising the steps:
1) location steel template, sloped position frame and built-in fitting is made according to the relative mounting positions of foot bolt in groups, relative position designing requirement according to foundation bolt in location steel template is provided with installing hole, installing hole diameter is greater than foundation bolt diameter, the lower link of sloped position frame is a horizontal plane, the upper link of sloped position frame in order to connect location steel template, and makes location steel template keep design inclination angle;
2) location steel template is placed on sloped position frame, their cross position line is overlapped, then location steel template is fixed on sloped position frame;
3) bearing concreting installs below extreme lower position and indwelling construction joint to foundation bolt, pre-buried built-in fitting;
4) establish a horizontal location frame, the lower link of horizontal location frame is connected with built-in fitting, and the upper link of horizontal location frame is in order to be connected with the lower link of sloped position frame, and the height of horizontal location frame need ensure that the installing hole in location steel template is in design height;
5) relocate plan-position, sloped position frame is put the upper link to horizontal location frame, their cross position line is overlapped, is fixedly connected with horizontal location frame and sloped position frame;
6) all foundation bolts penetrated one by one and be fixed in the installing hole in location steel template, making all foundation bolts stretch out the length of steel form identical, the then anchor block of mounting foot bolt bottom.
Foundation bolt is fixed except the three-dimensional coordinate on top, also needs to ensure that gradient meets the requirements.All be provided with nut screwing clamping foundation bolt at location steel template surface and bottom surface, be not only foundation bolt and provide three-dimensional localization accurately, also realize the location of gradient.Tradition sizing stock method is installed relatively, adopts said method to implement, significantly reduces surveying work amount, decreases because measuring the repeatedly on-the-spot adjustment workload brought, installation rate is fast one times, installation accuracy is more guaranteed, and the engineering overall duration is shortened.The application of the method, reaches high-quality, efficiently target.
Patent formula two: further, in described step 6), with little angle steel, foundation bolt bottom is fixed again after installing anchor block.Guarantee that in concreting process, the gradient of foundation bolt meets the requirements.

Detailed description of the invention
The specific embodiment of the present invention is further illustrated below in conjunction with example.
The location steel template 5 of annular, sloped position frame 8 and four pieces of built-in fittings 2 are made according to the relative mounting positions of foot bolt 4 in groups.Steel form aperture 0.5mm larger than foundation bolt diameter.
As shown in Figure 1, Figure 2 and Figure 4: location steel template 5 is placed on sloped position frame 8, their cross position line 12 is overlapped, then location steel template 5 is weldingly fixed on sloped position frame 8.Bearing concrete 1 is built to foundation bolt 4 and is installed below extreme lower position 200mm place's indwelling construction joint, and pre-buried four pieces of built-in fittings 2.
As shown in Figure 2 and Figure 4: establish four columns of angles to weld with four pieces of built-in fittings 2 respectively, and be arranged to a horizontal location face in angle steel upper end, between the column of angles, establish bridging, a rigidity level locating rack 3 is formed.Sloped position frame 8 is put on horizontal location frame 3, their cross position line 12 is overlapped, is welded and fixed sloped position frame 8.
As shown in Figure 3 and Figure 4: all foundation bolts 4 are penetrated location steel template 5 one by one, the length that all bolts stretch out steel form 5 is identical, tighten top nut 6 and lower nut 7, then the anchor block 10 of construction bolt bottom and nut 11 successively, be finally fixed with little angle steel 9 pairs of bottoms.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
