Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering technical field, especially relate to a kind of reinforcement arrangement of reinforcement method of malformation seam
And its structure.
Background technology
In Hydraulic and Hydro-Power Engineering building, for avoiding making due to temperature change, uneven settlement of foundation or geological process
Building structure deforms or destroys, and generally using the seam that width is about 2cm, structure is divided into several less separate single
Unit, makes building have the ability of stronger adaptation various modifications, and this seam is referred to as malformation seam.In order to keep each between movement joint
The independence of unit, during structural reinforcement, reinforcing bar is typically not passed through movement joint.The wide protection plus reinforcing bar of seam of movement joint itself is thick
Degree, forms the plain concrete area of wide about 20cm in deformation joint position.Traditional movement joint arrangement of reinforcement is as shown in figure 1, this scheme is main
It is that sealing (3), structural reinforcement are set in fabric structure (1) setting movement joint (2), movement joint (2) by top layer longitudinal reinforcement
(4), bottom longitudinal reinforcement (5) and transverse steel (6) composition, by sealing (3) impact, top layer and bottom longitudinal reinforcement are in movement joint
Place disconnects, and seam face reinforcing bar cannot be closed, formin concrete region (7).Analyze in terms of structure stress, due to plain concrete area no
Reinforced binding, plain concrete tensile strength is low, under external force, is susceptible to destroy.
Content of the invention
In order to solve the problems, such as the structural weak area that existing malformation seam leads to because of arrangement of reinforcement, the invention provides one kind exists
Deformation joint position strengthens method and its structure of arrangement of reinforcement, such that it is able to effective structural weak area eliminating movement joint, can improve
The safety of structure.
The present invention is achieved by following technical solution.
The present invention is the reinforcement arrangement of reinforcement method of such a malformation seam first, the method be by top layer longitudinal reinforcement and
Bottom longitudinal reinforcement bends up, and bent-up bar has a thickness of protection tier away from sealing, and then in vertical area, setting frame-type is strengthened
Reinforcing bar, the end of frame-type stiffener is respectively welded formation weld zone with top layer longitudinal reinforcement and bottom longitudinal reinforcement, thus will
Deformation joint position reinforcing bar is closed, and to strengthen the structural reinforcement of movement joint, eliminates deformation joint structure weak area, improves the operation of structure
Safety.
Based on said method, a kind of reinforcement reinforcement structure of malformation seam of the present invention is such, and this structure includes
Movement joint and its structural concrete of both sides, are provided with top layer longitudinal reinforcement, bottom longitudinal reinforcement and laterally in structural concrete
Reinforcing bar, is provided with sealing in movement joint, described top layer longitudinal reinforcement before not reaching movement joint under bend and formed one fall
Hook, described bottom longitudinal reinforcement is folded upward at before not reaching movement joint and forms a barb；Structural concrete is arranged
Frame-type stiffener, the end of this frame-type stiffener and top layer longitudinal reinforcement and bottom longitudinal reinforcement are respectively welded formation welding
Area.
Further, the barb of top layer longitudinal reinforcement and bottom longitudinal reinforcement is apart from least one cover to reinforcement of sealing
Thickness.The length that the barb of top layer longitudinal reinforcement and bottom longitudinal reinforcement rearward extends and the vertical position of frame-type stiffener
Intersect.
Wherein, the horizontal segment length that top layer longitudinal reinforcement and bottom longitudinal reinforcement bend up should meet concrete anchorage length will
Ask, the length of weld zone should meet the corresponding weld length of bar diameter and require.
The technology of the present invention is applied to Hydraulic and Hydro-Power Engineering building deformation seam position, such as Spillway chute, cushion pool bottom
The malformation seam muscle design of plate, irrigation canals and ditches etc..
The invention has the beneficial effects as follows：
The present invention passes through the reinforcing bar pattern of the traditional deformation joint position of adjustment, and arranges vertical strengthening ribs, makes deformation joint position
Arrangement of reinforcement is closed, and reduces the plain concrete scope of movement joint periphery, improves the rigidity of structure of movement joint, effectively eliminates
The weak area of movement joint, improves the structure safety of movement joint.Present configuration pattern is simple, strong applicability, and effect is obvious,
Safe and reliable, there are preferable economic advantages.
