Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~5, it is a kind of reduce construction area beam section support construction, including 5 lower part of the bent cap be fixed with it is perpendicular
Straight pier stud 6 including the cushion cap for Auxiliary support bent cap 5 and is fixed on the tubing string of cushion cap week side-lower, and the tubing string is by upper
Under gradually to offset in the middle part of supporting beam center, the tubing string has four or more, with the reduction of height, Ge Geguan
The area in the surrounded section of column is smaller and smaller.
In the present embodiment, the cushion cap is steel plate cushion cap 2, and tubing string is steel pipe column 3, adjacent 3 middle part of steel pipe column
Between be fixedly connected with round steel pipe 8(i.e. connecting tube), be also fixedly connected with connecting tube between the pier stud and tubing string.
It is contour in the middle part of each steel pipe column and pier stud to be fixedly connected with anchor ear, there is lug 71 on the anchor ear 7, it is described
8 end of round steel pipe is fixedly connected with a pair of of otic placode 81, and the lug 71 is inserted between otic placode 81, and the lug and otic placode have
The fixation hole of energy connection, the round steel pipe 8 is with anchor ear through being fixedly connected through the fixation hole of lug 71 and otic placode 81.
In the present embodiment, 71 quantity of lug and angle of the anchor ear 7 are carried out according to 8 position of round steel pipe to be connected
It is welded and fixed.
In the present embodiment, the cushion cap includes steel plate and the frame that is fixedly connected along steel plate edge with steel plate edge, is used for
Bent cap is assisted to carry beam section.
In the present embodiment, there are four the tubing string tools, and below the lower part insertion earth's surface of the tubing string, the structure is utilized
The certain native diagonal brace deep and triangular in shape of pillar embedment bears the part gravity on cushion cap in soil.
This concrete construction method is as follows, after 6 pouring molding of pier stud 5 and bent cap of beam section, starts setting up for temporary support.
The inclination foundation pit for first getting four specified sizes on the ground 4 of selected temporary support position with drilling machine, using loop wheel machine by steel pipe
Column 3 hangs in place to designated position, four 3 oblique cuttings of steel pipe column is entered in the foundation pit accomplished fluently fixed compacting, and maintained with loop wheel machine
The stabilization of steel pipe column 3, the anchor ear 7 of pier stud, circular steel tubing string is close in setting at whole intermediate altitude, and with round steel pipe 8
Anchor ear 7 on anchor ear 7 and steel pipe column 3 on pier stud is linked together and (utilizes the otic placode of lug and round steel pipe on anchor ear
It is stitched together, blending bolt is fixed), collectively form stable structure.Frame steel plate cushion cap 2 is ridden upon into steel pipe column 3 again
Top and fixation can remove loop wheel machine after fixing-stable, beam section be lifted on to the top of steel plate cushion cap 2 and bent cap 6, by bent cap 6
Beam section is supported jointly with steel plate cushion cap 2.It is all in place etc. all beam sections and after the completion of splicing, so that it may by steel plate cushion cap 2 to
Round steel pipe 8 and anchor ear 7 arrive steel pipe column 3(from top to bottom again) uninstall this temporary support structure.
The embodiment of the present invention uses steel plate and steel pipe column, is steel construction, intensity is big, and the steel pipe column on ground is entered using diagonal brace
The square frame steel plate cushion cap temporary support beam section surrounded with bar steel plate, as height reduces, the face that four steel pipe columns surround
Product is smaller and smaller.Adjacent steel pipe column is connected with round steel pipe at whole intermediate altitude, there are also pier studs and steel pipe column, are used to
Enhance the stability of temporary support.Steel pipe column is by transmitting the part gravity of beam section and steel plate cushion cap in deep soil come supporting beam
Section, it is ensured that meet and minimize occupied area in the case of supporting.This handstand gusseted can substantially reduce occupied area,
Construction suitable for many small land occupations.
