Abstract

Joints between precast concrete elements A joint between two adjacent faces (14) of concrete elements is formed by overlapping headed bar (16) with transverse studs (22) between the bars.

Description

Integrated structure between precast concrete element
The present invention relates in the process producing integrated structure between precast concrete element and use multiple grappling enhancing rod having head.
Have head be out of shape rod be at one end or two ends place be attached with the enhancing rod of the distortion of head, carbon steel such as with ribbing strengthens rod.Smooth enhancing rod is also that headed uses.The enhancing rod being all attached with head in this manual at two ends is described to double end post bolt, and no matter whether shank is in order to obtain better grappling but distortion.
By M.Keith Thompson, Antonio Ledesma, James O.Jirsa and John E.Breen the 103rd volume in March, 2006 of ACI's structure magazine (ACI Structural Journal) and April the 2nd interim disclosed title be describe in " by there being a bridge piece for rod grappling (Lap Splices Anchored by Headed Bars) " technical papers to use by there being a bridge piece of rod grappling to come to produce combination between prefabricated elements.This is mainly for they uses in bridge construction.This paper describes the mechanical characteristic of such integrated structure.The more detailed report made by identical author from May, 2002 is delivered by the Transportation Research Center of Texas university Austin as report 1855-3.These documents are referred to herein as Texas paper.The typical integrated structure width considered in those references is 10 inches (0.254m).
A rod is had also to be used to the enhancing of straight slab, especially for the high partial cut stress of reply pillar head.RFA-Tech system proposes to adopt the double end shear column bolt be welded on carrier/isolation track.The track of these bolster stake bolts is designed imaging ray and is equally placed in the slab of pillar to provide shearing resistance to strengthen.Be positioned vertically in slab around the axis being parallel of these post bolts and this pillar.Halfen and the Max Frank of Germany provides other patent systems for using around pillar head.
Special concern of the present invention needs straight slab to construct to create these problems of framework limiting multiple floor when constructing floor in large-sized multiple layer structure.These floors can be assembled by multiple precast concrete slab.Combination between these slabs and other structural members (concrete post, beam, wall as used with various configuration) must be firm in structure.Also wish to make to minimize the use of strong concrete in the processes forming these combinations.
The invention provides a kind of longitudinal integrated structure between two precast concrete elements, these precast concrete elements have separately have the adjacent surface of element to be combined to stretch out from these multiplely have a rod; These elements be positioned such that they separately have a rod to be staggered and overlap but do not contact with each other; And multiple have headpin bolt to be oriented to the length transverse to this integrated structure and have a rod transverse to these and have at these between rod, and these rods and post bolt are closed in concrete.Preferably adopt below in conjunction with structure, wherein multiple have a rod to interlock with the overlap joint combination described in these Texas papers, also add the track of bolster stake bolt, this track is supported on having on a rod of these overlaps along the length of this integrated structure and is suspended between these rods by multiple double end post bolt.When such enhancing structure is embedded in strong concrete, the firm structural combination of relative small size can be constructed.In the meaning analyzed, theoretical according to common post bolt and tie-rod, the transmission of power can be considered to a series of compression post bolt and tensioning tie-rod, enhances by the constraint effect of these intermediolateral column bolts on their bearing track the intensity that these compress post bolts.
When require to be formed above girder steel element in conjunction with, to have in these overlaps the post bolt providing intersection between a rod in the top flange that multiple single head post bolt can be welded in advance this beam.
Use the integrated structure of this form, these precast construction elements of this system can be manufactured into large element.Typically will light weight concrete construction be used to produce these elements to alleviate their weight and to make carrying and transportation logistics become easy.
Between the adjacent slab elements of this system, between beam and slab elements, between wall and slab elements and other similar situations combination require by another element of element temporary support.This typically by with bolt on the top of an element and to be provided by the multiple interim channel-section steel that cantilever action places on adjacent elements.
In order to make the present invention be understood well, now with reference to accompanying drawing, multiple embodiment being adjacent to integrated structure between thickness of slab plate is described, in the drawings:
Fig. 1 shows the phantom drawing of the floor embodiment that the local structure that employs integrated structure of the present invention goes out;
Fig. 2 shows the phantom drawing for constructing the multiple adjacent thick plates with humidification according to integrated structure of the present invention in position;
Fig. 3 shows the view of above-mentioned integrated structure; And
Fig. 4 shows the phantom drawing of the alternate embodiment on the floor that the local structure that employs integrated structure of the present invention goes out.
Floor in sandwich construction is assembled by multiple prefabricated lightweight concrete (LWC) slab 10.These slabs 10 are supported by multiple concrete beam 26 and pillar 28, and before constructing integrated structure between these beam and slabs and between adjacent slab, these elements are supported by multiple channel-section steel 30.
Integrated structure 12 constructs as shown in Figures 2 and 3.Each edge surface 14 of beam or slab 10 have stretch out from it a series ofly have a rod 16.In this example, these rods are illustrated in the layer that two vertical spacings open.Reinforcement by prefabricated in these slabs to make these slabs to lay to edge-to-edge, make a slab have a rod and an adjacent thick plates those have a rod to be staggered and overlapping and these rods do not contact with each other or collide with one another.These beams and the edge surface of slab have and are in the similar of same intervals and have a rod array, thus make it possible to the combination constructing same form between all these elements.
Length along this integrated structure lays two longitudinal rods 18, and the track 20 supporting a series of double end post bolt 22 places and uppermostly to have on a rod at these.These post bolts separate along this interorbital, thus make these post bolts to be positioned at these with being centered to have between a rod.These double end post bolts 22 are suspended on track 20 vertically.
In this embodiment, this track comprises two bars, and the head 24 of these double end post bolts is soldered on these bars.These double end post bolts 22 to be held in place with required interval at this and not to be formed the structural moiety of this integrated structure by this track.This track can be relative lightweight.The head of the foot of these double end post bolts is positioned within this integrated structure.
Below this integrated structure, provide template, thus make it possible to concrete to pour in gap to surround this reinforcement and by the height of the surfaced lift of this integrated structure to the abutment surface of these prefabricated slabs.Once complete combination, just remove these channel-section steels 30.
It is contemplated that use when there is the enhancing rod of 16mm to 25mm representative diameter, can by the lap length of 100mm adopt typical 200mm in conjunction with width.
In the diagram, steel framework 4 is made up of multiple girder steels 6 of the circumference limiting floor and at least one horizontal beam 8 in this circumference.This framework 4 is for supporting multiple light weight concrete construction (LWC) slab 10, and these slabs to be laid on framework 4 and to be connected on this framework.So define these integrated structures like that as described previously.
When integrated structure is positioned on beam 6, these can be replaced with a series of single head post bolts be welded on the top of this beam by the double end post bolt of rail supported.These single head post bolts serve the same role at this integrated structure.
