Description
Technical Field
The utility model relates to a pile foundation engineering pile extension field especially relates to a connected mode suitable for precast pile.
Background
The precast pile has the advantages of convenience in transportation and installation, quickness in construction, good crack resistance, stable quality, economy, environmental friendliness and the like, and is greatly developed and widely applied to pile foundations at present. However, the length of the precast pile is limited due to production, transportation, piling and other conditions, and the splicing of the pile is required at the construction site.
At present, two modes of welding connection and mechanical connection are mainly adopted for field splicing. The welding connection is to weld the precast pile end plates together on site, the connection strength between precast piles mainly depends on the welding seam connection strength, the welding seam quality has great influence on the welding connection strength, the discreteness of the welding seam quality is great due to weather and artificial influence of the site welding, and the connection reliability cannot be guaranteed; the mechanical connection is that two sections of piles are spliced together through a plug-in type mechanical joint or a clamp type mechanical joint, which puts high requirements on the processing precision of a mechanical connecting piece and the production quality of the precast pile, and the situation that the connection is unreliable due to the problems of the product quality and precision on site also happens occasionally. Therefore, the precast pile splicing structure which is simple in manufacturing process, convenient to install and reliable in connection quality is designed, and has important significance in further popularization of application of precast piles.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a connect neotype precast pile connection structure that reliability is good to prior art not enough.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a novel precast pile connection structure, includes upper segment stake, lower segment stake, upper segment stake bottom is equipped with upper segment pile-plate, and lower segment stake top is equipped with lower segment pile-plate, and upper segment pile-plate passes through welded fastening with lower segment pile-plate, upper segment pile-plate back is provided with several anchor reinforcing bars along vertical direction, has seted up corresponding slip casting anchor hole on lower segment pile-plate and the lower segment stake, the anchor reinforcing bar cooperates with slip casting anchor hole grafting.
Furthermore, a solidified material is poured into the grouting anchoring hole, and the anchoring reinforcing steel bar is bonded with the grouting anchoring hole through the solidified material.
The further solidification material is high-strength cement mortar or epoxy resin.
Further, an anchoring pier head is arranged at the bottom end of the anchoring steel bar.
And further, the top ends of the anchoring reinforcing steel bars and the upper pile end plate are fixed through welding.
And further, the top end of the anchoring steel bar is connected with the upper pile end plate through threads.
The utility model has the advantages that: the utility model discloses an anchor reinforcing bar and slip casting anchor hole's grafting cooperation has improved the connection precision between upper segment stake and the lower segment stake, has strengthened the reliability of connecting, the anchor reinforcing bar end of adoption is equipped with the anchor pier nose, through with slip casting anchor downthehole cement mortar bonding energy that excels in effectual and lower segment stake anchor, anchor reinforcing bar is longer with slip casting anchor hole simultaneously, it is more even to have guaranteed that joint department atress has carried out welded connection in upper and lower end plate laminating department, the joint strength who further improves the joint.
To sum up, the utility model discloses a novel connection structure that precast pile connection provided has good atress performance, and it is clear and definite to pass the power route, and simple and on-the-spot simple to operate of manufacturing process has wide application prospect.
Drawings
FIG. 1 is a schematic view of the pile splicing of the present invention;
fig. 2 is a schematic view of the pile splicing connection of the present invention.
Shown in the figure: an upper pile section 1; a lower pile section 2; an upper pile end plate 3; a lower pile end plate 4; anchoring a steel bar 5; grouting anchoring holes 6; anchoring the pier head 7.
Detailed Description
The embodiment of the utility model discloses an: for the pile extension of making precast pile be convenient for site operation, guarantee the connection quality of joint department simultaneously, consequently design a manufacturing process simply, the reliable pile extension structure of connector, as shown in fig. 1-2, including upper segment stake 1, lower segment stake 2, upper segment stake 1 bottom is equipped with upper segment stake end plate 3, lower segment stake 2 top is equipped with lower segment stake end plate 4, upper segment stake end plate 3 passes through welded fastening with lower segment stake end 4 board, upper segment stake end 3 board back sets up four anchor reinforcing bars 5 along vertical direction, corresponding slip casting anchor hole 6 has been seted up on lower segment stake end plate 3 and the lower segment stake 2, anchor reinforcing bar 5 and slip casting anchor hole 6 are pegged graft the cooperation. During installation, four anchoring steel bars 5 are inserted into corresponding grouting anchoring holes 6, so that the upper pile 1 and the lower pile 2 are connected in an aligned mode, and then the joint of the upper pile end plate 3 and the lower pile end plate 4 is welded, and the connecting strength of the joint is guaranteed.
The grouting anchoring hole 6 preferred in the embodiment is filled with a solidified material, and the anchoring steel bar 5 is bonded with the grouting anchoring hole 6 through the solidified material. Before the anchoring steel bar 5 is inserted, a solidified material is poured into the grouting anchoring hole 6, and the anchoring steel bar 5 is solidified and bonded after being inserted into the grouting anchoring hole 6, so that the anchoring steel bar 5 is anchored in the lower pile section 2, and the connection strength is further enhanced.
The preferred setting material for this embodiment is high strength cement mortar or epoxy resin.
The bottom end of the preferred anchoring steel bar 5 of the embodiment is provided with an anchoring pier head 7. Anchoring pier nose 7 is thicker than anchoring reinforcing bar 5, can be more accurate with slip casting anchor hole 6 grafting improvement connection accuracy, and after high strength cement mortar solidifies, anchoring reinforcing bar 5 is more difficult to follow slip casting anchor hole 6 separation, further strengthens joint strength.
The top end of the anchoring steel bar 5 preferred in the embodiment is fixed with the upper pile end plate 3 through welding.
The embodiment of the utility model discloses an embodiment two: the top of the anchoring steel bar 5 is provided with an external thread, the upper pile end plate 3 is provided with a corresponding tensioning threaded hole, the two are connected through the thread, and the rest of the structures in the embodiment are the same as those in the first embodiment, and are not repeated.
