Abstract
The utility model discloses a pre-cast concrete structural member capable of being longitudinally connected. In a cast-in-place concrete structure, the mechanical connection methods such as lap joint connection, welding connection or extrusion sleeves are always adopted in the connection of reinforcing steel bars, the lap joint connection of the reinforcing steel bars is the simplest, construction of the mechanical connection methods of the welding connection or the extrusion sleeves is complex, the connection of the reinforcing steel bars must be completed before concrete is cast, and the mechanical connection methods are not suitable for the assembly-type construction method of a pre-cast concrete structure. The pre-cast concrete structural member comprises a pre-cast concrete member body (1). A pre-buried longitudinal bar (2) is arranged inside the pre-cast concrete member body (1). A longitudinal bar preformed hole (3) is formed next to the pre-buried longitudinal bar (2). The bottom end of the pre-buried longitudinal bar (2) and the longitudinal bar preformed hole (3) are located inside a ribbing reinforcing bar (7). The upper end and the lower end of the longitudinal bar preformed hole (3) are communicated with a grout outlet hole (5) and a grout pouring hole (4) respectively. The pre-cast concrete structural member is used for the connection of the longitudinal reinforcing steel bars between the pre-cast concrete structural members.
Description
technical field:
the utility model relates to a kind of precast concrete member that can vertically connect.
background technology:
in cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect, be welded to connect or the mechanical connection method such as compression sleeve more, wherein the overlap joint of reinforcing bar connects the simplest, be welded to connect or the construction of the mechanical connection such as compression sleeve comparatively complicated, but these traditional constructions must complete the connection of reinforcing bar before fluid concrete, be not suitable for the fabricated construction engineering method of precast concrete.
summary of the invention:
the purpose of this utility model is to provide a kind of precast concrete member that can vertically connect, and utilizes the vertical muscle hole to be provided on the pre-buried vertical muscle of precast unit side to realize the connection between longitudinal reinforcement, simple to operate, dependable performance.
above-mentioned purpose realizes by following technical scheme:
a kind of precast concrete member that can vertically connect, its composition comprises: the precast unit body, there is pre-buried vertical muscle in described precast unit body, described pre-buried vertical muscle side arranges vertical muscle preformed hole, the bottom of described embedded bar, described vertical muscle preformed hole are positioned at the inside of ribbing reinforcing rib, and the two ends up and down of described vertical muscle preformed hole communicate with slurry outlet, grout hole.
the described precast concrete member that can vertically connect, described ribbing reinforcing rib comprises reinforcing rib, rib, described rib is the high-intensity direct reinforcing bar, described rib and described reinforcing rib colligation or be welded to connect, described reinforcing rib and described rib connect and compose a reinforcing cage, described rib is in described reinforcing rib inboard or the outside, and described reinforcing rib is spiral bar or ring muscle, and described rib is 3,4,5 or 6.
the described precast concrete member that can vertically connect, described vertical muscle preformed hole crust is tangential on pre-buried vertical muscle, and described vertical muscle preformed hole inwall is corrugated, helical form, groove shape or point-like.
beneficial effect:
1. the reinforcing bar attended operation that the utility model is realized is simple, and work progress does not need complicated plant equipment and facility, does not also need power consumption, has solved the comparatively complicated problem of connection construction of existing building trade reinforcing bar.
2. the existence of the pre-buried ribbing spiral bar of the pre-buried vertical muscle of the utility model and vertical muscle hole to be provided periphery makes reinforcing bar link position concrete form the three dimension stress stress state, limited the radially development of internal fissure of concrete, adhesion strength is improved, and anchorage reliability strengthens; And the increase of longitudinal rib makes the globality of spiral bar stronger, strengthened the resistance to torsion of connecting portion; Be connected and compare with traditional sleeve pipe, the ribbing spiral bar does not make concrete delamination within being wrapped in concrete, so switching performance is more reliable, is suitable for again the construction characteristics of housing industrialization precast concrete.
3. the utility model construction quality is easy to guarantee, job site is dry operation substantially, has fully avoided all disadvantages of traditional reinforcing bar connected mode.
4. the utility model building course environmental protection and energy saving, reduce costs, save construction fund.
