The present invention relates to a kind of architectural prefab, particularly a kind of jointing body of reinforcing bar preformed pile stake end.
The development of society reduces effective usable floor area in soil day by day, forces building as far as possible to spatial development, causes the single pile load of pile foundation increasing.Therefore, when increasing the pile cutoff sectional area, the length of stake group also rises to tens meters by tens meters thereupon.Precast reinforced concrete pile is with its reliable in quality, and the duration lacks and is subjected to generally adopting.But, because the restriction of construction and traffic condition can only connect with joint by prefabricate.Traditional welding pile joint need add parallels plate at the joint area of up and down stake and proofread and correct pile body, and making up and down with the vertical welding of angle steel then, stake is connected as a single entity.It is flat that one of defect of this welding stake is that two contact end face is difficult to adjust, and makes the joint large tracts of land not contact and do not have stressed; Being second that vertical welding is difficult for welding of defect and poor quality and welding work efficiency are low.In construction way, shut down often and cause a large amount of work holdup, influence programming, caused the significant wastage of social benefit and business economic benefit because of handling the pile joint problem.
The present invention has carried out improving design to traditional welding pile joint body, and purpose is to make two pile joint end faces to be easy to leveling, the welding quality that improves two pile joint places and work efficiency and then speeds up the work.
Described invention comprises the stake pile body, the main muscle of last stake, a following pile body, following main muscle, it is characterized in that: be welded with top connection body riser (4) on the main muscle of stake (2) on stake pile body (1) joint area on described, be welded with a top connection body flat board (5) on the top of this top connection body riser (4); On a described following pile body (11) following main muscle of joint area (10), be welded with lower contact body riser (9), be welded with a lower contact body flat board (8) near this certain position place, lower contact body riser (9) end; The cross section of the last pile joint body that is made of described top connection body riser (4) and top connection body flat board (5) the cross section by the following pile joint body of described lower contact body riser (9) and lower contact body flat board (8) formation is little so that on the pile joint body can embed down among the pile joint body; Leave the packing layer (7) that one deck can be filled chill property filler between pile joint body and the following pile joint body on described.For hollow pile, a circle packing retaining ring (13) arranged on the periphery more nearby of center at described lower contact body flat board (8).
So the welding pile joint of design can make the stake group of large-scale static pressure or hammering ram machine construction bury about general speed doubles, and the welding work efficiency improves one to two times; Owing to change original vertical vertical position welding into horizontal fillet welding, therefore make weld seam full, tensile strength obviously improves; Owing in stake end packed layer, filled the chill property material that is higher than concrete strength, therefore made the whole compressive property of stake group greatly strengthen.
In following description of drawings and embodiment, will specifically describe its structure and advantage.
Description of drawings.
Fig. 1 is a structural principle sectional view of the present invention.(1) is last stake pile body among the figure, and (2) are the main muscle of last stake, and (3) are the welding cushion block, and (4) are top connection body riser, and (5) are top connection body flat board, and (6) are attachment weld, and (7) are packing layer, and (8) are lower contact body flat board; (9) be lower contact body riser, (10) are following main muscle, and (11) are a following pile body.
Fig. 2 is an embodiment of welding pile joint of the present invention, is a hollow pile joint structural representation among the figure.Wherein (4) are top connection body riser, and (5) are top connection body flat board, and (8) are lower contact body flat board, and (9) are lower contact body riser.(12) be the pile sinking cushion block, (13) are the filler ring washer.
The performance explanation.
The connection procedure of described invention in construction is as follows:
Strength from the stake machine does not need pile cover by pile cover＜clamping plunging, have only a top static pressure method and hammer to go into method and just use pile cover act on pile sinking cushion block (12), (12) make down upper end (8)-(9) of promptly following of pile joint body and the absolute altitude that following pile joint body (10)-(11) are sink to the pile extension requirement simultaneously.The pile sinking cushion block (12) of taking away, sling go up that lower end (4)-(5) that stake pile body (1)-(2) and top connection body promptly go up make it and following pile joint body plane between distance about maintenance 15cm, be convenient to implement filler, in order to forming a packing layer (7), after pouring into the chill property high strength filler of heating, the pile joint body connects and correction about allowing, and laterally executes fillet welding (6) then at once, make the filler resistance to compression, weld seam tension and form a more complete pile joint.
The work efficiency time difference in a construction embodiment compares with regard to conventional piles joint and pile joint of the present invention below:
One group of stake of three section two joint of example 550mm * 550mm * 30 meters enters speed before the bearing stratum on average greater than 2.5m/ minute with 340 static pressure machines construction pile cutoff, and time needs 12 minutes always bury.
A. traditional jointing usefulness welding rod is 47
1. electric welding machine construction adds parallels plate and proofreaied and correct pile body 3-5 minute, and laterally face down bonding is about 18 minutes, installs the long 300mm4 root of 80mm angle steel additional and needs 45 minutes vertical welding time approximately, altogether 67 * 2 joint=146 minute.
2. two electric welding machines construction: add and adjust pad 3～5 minutes, laterally face down bonding is 9 minutes, installs 4 in angle steel additional and needs 23 minutes vertical welding time kind approximately, amount to 35 * 2 joint+12=82 minute.
