Abstract
The invention discloses a connecting method of a supporting beam at a second path or under the second path and a vertical column pile in a deep foundation pit of a basement of building engineering, and relates to the technical field of building construction engineering. The connecting method comprises the following steps of: when a steel-bar cage on a pile body of the vertical column pile is manufactured, designing an elevation position at the supporting beam at the second path or under the second path, and welding and fixing a steel sleeve and a stirrup of the vertical column pile at the elevation position; and after the pile body is formed and an earthwork is excavated to the elevation position of an internal supporting beam at a corresponding path, chiseling concrete at the steel sleeve of the vertical column pile, exposing the steel sleeve completely, bending a steel bar at the end head of the supporting beam, and then welding with the steel sleeve. The connecting method disclosed by the invention has the advantages that the construction technology can be adopted when the construction of the internal supporting beam in the foundation pit supporting engineering is carried out or other similar engineering needs to connect concrete at the middle part of the pile or the column and cast the structure, so that not only is no damage generated for the structure of the pile body or a column body, but also the anchoring length of a reinforced beam is forcefully guaranteed, the construction is convenient, the construction period can be effectively shortened, and the whole stability of a structure system is also practically guaranteed.
Description
Technical field
The present invention relates to the technical field of construction that is connected of second road in the construction engineering technical field, particularly deep foundation ditch or following brace summer and stand column pile.
Background technology
In construction work basement deep foundation ditch, support in the concrete structure construction; Brace summer is shelved on the stand column pile top in first road, and second road or following brace summer are normally treated to adopt after soil excavation to the design elevation method of bar planting to carry out brace summer to be connected with stand column pile.
This bar planting method of attachment is: on the stand column pile pile body, hole with auger earlier, in the hole, inject bar planting glue behind the clear hole, at last reinforcing bar is inserted.System itself is stressed bigger because of deep foundation pit support engineering inner supporting body; Each link structure construction is all carrying out strict control; But must on stand column pile, hole during bar planting, this is very big to the pile body structural damage, and the length of bar planting and muscle position receive column pile body master's muscle and stirrup to influence and can not guarantee.In addition, boring causes support system to produce destabilizing factor in case cleaning totally will directly not influence the whole connectivity of reinforcing bar and stand column pile.
In sum, adopt the bar planting method to carry out brace summer and structure has been caused serious potential safety hazard, can not ensure personnel's construction operation safety under the deep foundation ditch with being connected of stand column pile.
Summary of the invention
The object of the invention provides a kind of have interior second road of construction work basement deep foundation ditch of safety guarantee or the method for attachment of following brace summer and stand column pile.
When the present invention makes at stand column pile pile body reinforcing cage; In second road or following brace summer design elevation position the welding of steel bushing and stand column pile stirrup is fixing; After treating pile body shaping and soil excavation to the interior brace summer absolute altitude position in corresponding road; Cut the concrete at stand column pile steel bushing place, steel bushing is exposed fully, then the reinforcing bar bending back of brace summer termination is welded with steel bushing.
Can adopt this construction technology when brace summer when construction or other similar engineering need after stake or pillar middle part connect concrete, water structure in carrying out foundation pit supporting project; Use should technology not only not produce damage to pile body or shaft structure; And the anchorage length of beam muscle has also obtained strong guarantee; Easy construction, has also guaranteed the resistance to overturning of structural system conscientiously at effective reduction of erection time.
Description of drawings
Fig. 1 is that stand column pile is connected global design figure with brace summer.
Fig. 2 is steel bushing and stand column pile stirrup welding plan view.
The specific embodiment
Among the figure, 1 is Support Position, first road, and 2 is Support Position, second road, and 3 is steel bushing, and 4 for supporting beam main tendon, and 5 is the brace summer stirrup, and 6 is main muscle and steel bushing soldered, and 7 is pile body, 8 be foundation ditch at the bottom of, 71 is stand column pile master muscle, 72 is the stand column pile stirrup.
When stand column pile pile body reinforcing cage is made in second road or following brace summer design elevation position 2 with steel bushing 3 stirrup full weld seam welding with stand column pile 7, form the long weld seam 6 of 300mm.
Treat that pile body is shaped and soil excavation to the interior brace summer absolute altitude position in corresponding road after, cut the concrete at steel bushing 3 places, steel bushing 3 is exposed fully, during the brace summer construction on steel bushing according to drawing with the red paint reinforcing bar welding position of drawing.
To support the steel bar end bending back of beam main tendon 4 with welding machine and weld with steel bushing 3, weld length is one side welding 10d, double welding 5d, and wherein d is a bar diameter, and weld seam requires full, and the surface does not allow defectives such as pore, slag inclusion, crater crack, arc scratch.After management, Party A's acceptance(check), can carry out the hidden work of reinforcing bar.
Claims (1)
1. the method for attachment of second road or following brace summer and stand column pile in the construction work basement deep foundation ditch; It is characterized in that when stand column pile pile body reinforcing cage is made; In second road or following brace summer design elevation position the welding of steel bushing and stand column pile stirrup is fixing, treat that pile body is shaped and soil excavation to the interior brace summer absolute altitude position in corresponding road after, cut the concrete at stand column pile steel bushing place; Steel bushing is exposed fully, then the reinforcing bar bending back of brace summer termination is welded with steel bushing.
