Description
Technical field
The utility model belongs to building structure aseismatic reinforcement and repair technical field, between more particularly to a kind of prestressed building blocks window
Wall.
Background technology
Masonry structure is as important architecture structure form, and ownership is very big in China's town building, and the amount of having is big, face
It is wide that there are features.But the earthquake fortification level of this class formation their location is usually relatively low, is easily damaged in earthquake.Masonry
Wall between windows participate in Structural Energy Dissipation as important anti-vibration defense lines, and more serious damage has occurred in earthquake.
Restorative procedure is predominantly removed to be damaged to mend as former state after wall and be built after being shaken at this stage for wall between windows, has not been considered secondary
It is influenced caused by earthquake, damaged part often still destroys in lower secondary earthquake.And such reinforcement means is to structure
Failure mode is not added with distinguishing, and the destruction sequence of component is also not required, reinforcement technique is not reasonable, and there are more serious peaces
Full hidden danger.
In view of the shortcomings that above-mentioned tradition restoring and fastening method, be badly in need of compensating its defect with novel technical method.
Utility model content
The purpose of this utility model is to provide a kind of prestressed building blocks wall between windows, to solve above-mentioned technical problem.
The utility model is on the basis of existing conventional method shortcoming is summarized, with reference to the failure mode of masonry structure wall between windows
With force-mechanism, using " pre-control " thought as guidance, in repairing and reinforcement after structure creates and shakes, propose a kind of period it is short,
The scale of construction is small, constructing operation easily ruggedized construction.Tension mechanical property (ductility) of the structure based on reinforcing bar well, utilizes post-tensioning
Good prestressed principle after method reinforced bar stretching can be provided region, realizes wall between windows prestressed reinforcement.In newly-built structure
When building wall between windows by laying bricks or stones, the steel bar arrangement that both ends are carried hot candied head has built one layer of wall between windows by laying bricks or stones in the mortar joint of different skin bricks
Place perforated steel plate item along straight wall at this wall between windows both ends afterwards, position using each reinforcing bar of each layer pass through bolt hole thereon as
Standard.By manually tighten the nested nut in reinforcing bar both ends with realize reinforcing bar apply needed for prestressing force, after in perforated steel plate
Paving slurry plastering is carried out on the outside of item.This method does not influence normal construction, is not take up exceptional space, does not change structure function characteristic, can
Significantly improve anti-seismic performance of the masonry structure wall between windows in earthquake.
To achieve these goals, the utility model adopts the following technical solution：
A kind of prestressed building blocks wall between windows, being built including breast, on breast has wall between windows；First skin of wall between windows is brick
Two horizontal plain bars are set in the screed between body and the second skin brick setting；At wall between windows medium position and top
Two horizontal plain bars are also provided in screed between two skin brick settings；It is hot candied that the both ends of plain bar are equipped with end
Head, end wire drawing head are stretched out outside wall between windows；Wall between windows both ends vertical wall places four pieces of perforated steel plate items, the end of plain bar
Wire drawing head in portion's passes through the corresponding bolt hole on perforated steel plate item, and wire drawing head in end is consolidated with corresponding perforated steel plate item by nut
It is fixed.
Further, nut is applied with prestressing force to corresponding plain bar.
Further, the intersection of end wire drawing head and corresponding nut is welded and fixed.
Further, perforated steel plate lateral surface is equipped with grout layer, wraps the end wire drawing head and spiral shell of plain bar
It is female.
Further, a diameter of 8mm of plain bar.
Further, the length of end wire drawing head is 35mm.
Further, the thickness of perforated steel plate item is 4mm, width 30mm, and length is identical with the height of wall between windows.
Further, two plain bars in every layer be symmetrically arranged in corresponding brick setting surface far from edge 15mm at.
The utility model carries out end wire drawing after calculating interception by practical interfenestration to required tension reinforcing steel bar, presses
Wall between windows height chooses steel plate strip and the trepanning in steel plate strip of corresponding position forms steel with holes on wall between windows by tension reinforcing steel bar
Lath.It is aforementioned it is ready after start to build wall between windows by laying bricks or stones, build by laying bricks or stones to certain altitude, two steel be placed in parallel by regulation spacing
Wall between windows both ends specific length is stretched out in muscle, each end of reinforcing bar, is laid with mortar later in brick layer and rebar surface specific thickness.Continue
It builds by laying bricks or stones, repeats above-mentioned construction technology, until wall between windows build completion by laying bricks or stones, reinforcing bar laying finishes.At wall between windows both ends along its straight wall side
Perforated steel plate item is placed to wall is adjacent to, position should ensure that reinforcing bar passes through bolt hole, and nested nut is in reinforcing bar later
On end wire drawing head, by tightening nut to prestressing force needed for reinforcing bar application, each end junction is reliably welded, in band
Paving slurry plastering is carried out on the outside of the steel plate strip of hole, conserving to the stipulated time can come into operation.
Required reinforcing bar be plain bar, a diameter of 8mm, length be the additional 40mm of interfenestration, additional 40mm length
It is used as wall between windows both sides across perforated steel plate item with nested nut, length of string is each 35mm in both ends, for tightening nut
It is used to specified value with applying prestressing force.Selecting for nut specification should be standard with the first cause of end reinforced wire drawing.Perforated steel plate
Thickness is 4mm, width 30mm, and length takes the height of wall between windows to be advisable, by tension reinforcing steel bar on wall between windows corresponding position
Advance machine drilling forms perforated steel plate item in steel plate strip, and hole diameter 9mm ensures that reinforcing bar without hindrance can pass freely through.
The grades such as strong of masonry mortar and brick setting are chosen by normal requirement, and masonry way is using routine building method.
Relative to the prior art, the utility model has the advantages that：
The utility model enhances it as a kind of prestressed building blocks wall between windows while wall between windows wall stiffness is not increased
Anti-seismic performance and ductility.By the stretch-draw prestressing force feature that reinforcing bar can be formed after tensioning, in newly-built wall between windows building wall
Deformed bar is laid in along wall height among masonry wall in the process.By post stretching tension reinforcing steel bar, apply to wall between windows and in advance should
Power.Increase the shearing strength of wall using the prestressing force being previously applied in seismic process, when being destroyed so as to reach delayed fracture
Between purpose.The utility model improves the anti-seismic performance of wall, simplifies reinforcement technique scheme, newly-built structure with it is extensive after calamity
It can be applied in multiple reconstruction, notable economic and social profit can be brought.
