Abstract
The invention relates to a quincuncial mortar joint mortar reinforced masonry structure belonging to the technical field of old building reinforcement. The quincuncial mortar joint mortar reinforced masonry structure comprises an original masonry structure wall and also comprises original low-grade mortar and newly backfilled high-grade mortar. Mortar joint mortar is of the quincuncial mortar joint mortar reinforced masonry structure, namely the horizontal part of an original mortar joint wall is excavated in a quincuncial layout way and is backfilled with mortar. According to the quincuncial mortar joint mortar reinforced masonry structure, the low-grade mortar in the wall is replaced with the high-grade mortar, so that the compression resistance and shear resistance of a masonry are improved, and the safety performance of a house is ensured; and meanwhile the construction cost is relatively low, and the original space is not occupied after the wall is reinforced, so that the quincuncial mortar joint mortar reinforced masonry structure can be widely applied to house reinforcement.
Description
Technical field
The present invention relates to a kind of employing quincunx mortar joint mortar reinforcing masonry structure and construction method thereof, mainly for solving the lower problem of old masonry residence intensity, belonging to reinforcing technique field.
Background technology
Along with the progress of the development of human society, the raising of the level of the productive forces and science and technology, design of building structures standard improves constantly, and people also more and more pay attention to the safety of house.In the face of a large amount of masonry structure building existed now, more reinforcement means arises at the historic moment, in the face of the Positive and Negative Aspects of various reinforcement means, select a kind of rationally effectively, reinforcement means that economy is higher become the basic demand of most resident.The present invention is based on formula (7.2.7-2) content in " seismic design provision in building code " and think that the size of mortar strength can play very large effect in the resistance to compression and shearing resistance of whole masonry in masonry structure mortar joint, and configuration level reinforcing bar improves little to the intensity of masonry structure, and adopt steel reinforcing method cost higher.Therefore, rationally reinforcement means is particularly important easily in selection, and the reinforcing expense can saving peasant like this can provide reinforcement means safely and effectively again, increases the application life in house.Can predict, along with people are to the raising of self dwelling environment security requirement and the requirement to economy, if this technology is promoted, significant economic benefit will be had in Strengthened Masonry Walls house.
Summary of the invention
The present invention adopts mortar that in quincunx mortar joint mortar reinforcing masonry structure mortar joint, label is lower to replace to mortar compared with high grade, and object improves resistance to compression and the shear resistance of part mortar, and the resistance to compression of whole masonry and shear resistance are effectively improved.Mainly can not reach code requirement to solve existing masonry structure building anti-seismic performance, and adopt other reinforcement means problem costly.
Technical scheme of the present invention is as follows:
A kind of employing quincunx mortar joint mortar reinforcing masonry structure, comprises former Masonry Wall, also comprises the high grade mortar of former low grade mortar and new backfill.Described mortar joint mortar replacement technology adopts quincunx replacement method, is namely made an opening through former mortar joint body of wall lateral part by quincunx arrangement, and backfilling mortar.Described low grade mortar application chisel is rejected, and described chisel diameter must not be greater than gray seam thickness; Described high grade mortar should with original wall body and former low grade mortar bonding firm; Described vertical equity groove is made an opening through every two to three skin bricks, and it is made an opening through the distance that length and adjacent two makes an opening through between hole and should determine as calculated according to body of wall pressurized and situation of being cut.
Above-mentioned employing quincunx mortar joint mortar reinforcing masonry structure and construction method thereof, adopt following steps:
Step one: body of wall both sides floated coat is rejected, exposes structural plane;
Step 2: need the position of replacement mortar and vertical equity groove size also forced with chisel according to drawing requirement determination body of wall, wherein the diameter of chisel must not be greater than the thickness of mortar joint;
Step 3: after mortar joint is cut a hole, should spray water and drench in the former surface joined with mortar joint, to guarantee the caking ability of former low grade mortar and high grade mortar and high grade mortar and block surfaces;
Step 4: after mortar joint drenches, inserts high grade mortar, and high grade mortar should be inserted from body of wall both sides of edges to centre and progressively extrude, and makes the degree that high grade mortar reaches closely knit;
Step 5: reach both sides surface layer mortar of plastering a wall after some strength until mortar joint mortar.
Beneficial effect:
Advantage of the present invention is that adopting high grade mortar to replace former low grade mortar improves masonry structure intensity, and its constructing operation is simple, and construction cost is lower, and after wall reinforcement, indoor still keep original usable floor area, does not take original interior space.Utilize the raising of mortar strength thus the effective intensity improving masonry structure, make it meet shockproof requirements.
Owing to utilizing mortar joint mortar replacement technology reinforcing masonry structure housing construction simple, cost is lower, substantially increases the intensity of masonry structure building simultaneously, ensure that the safety in utilization in house, the personnel that minimizing disaster causes and property loss, add the application life in house.Can predict, along with people are to the raising of self dwelling environment security requirement and the requirement to economy, if this technology is promoted, significant economic benefit will be had in Strengthened Masonry Walls house.
Accompanying drawing explanation
Fig. 1 is for adopting quincunx mortar joint mortar reinforcing masonry structure elevation;
Fig. 2 is the 1-1 sectional drawing of Fig. 1.
In figure, 1: former masonry wall; 2: former low grade mortar; 3: high grade mortar.
Detailed description of the invention
A kind of employing quincunx mortar joint mortar reinforcing masonry structure, comprises former Masonry Wall 1, also comprises the high grade mortar 3 of former low grade mortar 2 and new backfill.Described mortar joint mortar replacement technology adopts quincunx replacement method, is namely made an opening through former mortar joint body of wall lateral part by quincunx arrangement, and backfilling mortar 3.Described low grade mortar 2 is applied chisel and is rejected, and described chisel diameter must not be greater than gray seam thickness; Described high grade mortar 3 should bond firmly with original wall body 1 and former low grade mortar 2; Described vertical equity groove is made an opening through every two to three skin bricks, and it is made an opening through the distance that length and adjacent two makes an opening through between hole and should determine as calculated according to body of wall 1 pressurized and situation of being cut.
Above-mentioned employing quincunx mortar joint mortar reinforcing masonry structure and construction method thereof, adopt following steps:
Step one: body of wall 1 both sides floated coat is rejected, exposes structural plane;
