Abstract
The present invention relates to a kind ofly adopt prestressed thin reinforced net sheet to be used for the earthquake-resistant building of newly-built multilayer brickwork load-bearing is set up defences, this method is according to the earthquake intensity of locality and constructs collar tie beam and the constructional column place that requires at multi-story masonry building, after laying prefabricated thin muscle net sheet and applying prestressing force, build by laying bricks or stones or whitewash with high-grade cement mortar through anchoring.At the weak part of masonry, can lay especially and strengthen thin muscle net sheet.
This method have reduce on-the-spot water operation, construction easily, reduction of erection time, saving material, advantage such as construction costs is low, anti seismic efficiency is good.
Description
The present invention relates to a kind of prestressed thin reinforced net sheet and be used for the method that newly-built masonry house is provided fortification against earthquakes.This method is specially adapted to the civilian construction of multilayer brickwork load-bearing and provides fortification against earthquakes.The multistory civil building that also is applicable to structural clay tile, fly ash brick, hollow concrete building block etc. is provided fortification against earthquakes.
Civilian construction such as a large amount of now dwelling houses, school, hospital, shop, cinema mainly adopt brickwork load-carrying members mode.No matter masonry adopts solid clay brick, still adopts structural clay tile, fly ash brick, hollow concrete building block etc., and all because of its fragility relation, anti-seismic performance is bad.A large amount of earthquake experiences show, the multilayer brick masonry housing of no muscle has cracking when earthquake intensity 6 is spent, and begin when 7-8 spends to damage, will heavy damage when 9 degree are above or collapse.For making newly-built multi-story masonry building reach the purpose of antidetonation.In recent years, China adopts the reinforced concrete circle beam of sealing and the measure of constructional column to provide fortification against earthquakes mostly, and has formulated the codes and standards figure that provides fortification against earthquakes, and these measures are fine to the shock strength, globality and the non-deformability effect that improve the house.But the construction costs height, on-the-spot water operation is many, and construction is complicated, and the cycle is long.
The objective of the invention is problem, propose a kind of anti-seismic performance that adopts prestressed thin reinforced net sheet to improve newly-built multilayer brickwork load-carrying members house at above-mentioned existence.This method is at newly constructed house collar tie beam and constructional column place to be set, lay prefabricated thin muscle net sheet, apply an amount of prestressing force, the banding constraint brick masonry, and with the anchor pin with thin muscle net sheet and masonry anchoring, build by laying bricks or stones or whitewash with high-grade cement mortar at last, make it to combine, reach the purpose of providing fortification against earthquakes with body of wall is effective.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is along the prestressed thin reinforced net tile of wall collar tie beam schematic diagram.
Fig. 2 is the prestressed thin reinforced net tile of two a gables collar tie beam schematic diagram.
Fig. 3 is the prestressed thin reinforced net tile of an internal partition wall collar tie beam schematic diagram.
Fig. 4 is the prestressed thin reinforced net tile of an outer pier constructional column schematic diagram.
Fig. 5 is four big angles prestressed thin reinforced net tile constructional column schematic diagrames.
The ground collar tie beam schematic diagram that Fig. 6 strengthens usefulness for the maximum shear layer is provided with vertical thin muscle net sheet and the fine steel rib net sheet of level make up.
Referring to accompanying drawing.Its method is: at needs the collar tie beam place is set.See Fig. 1, Fig. 2, Fig. 3, when treating that body of wall is built at the bottom of the collar tie beam absolute altitude, horizontal thin reinforced mesh 2 be placed on the body of wall 1, apply an amount of prestressing force after, shop one deck high grade Masonry cement mortar 3, then masonry panel 1.The per pass collar tie beam is all so installed with which floor horizontal thin muscle net sheet 2.After treating that body of wall binds, lateral surface at collar tie beam, lay vertical fine steel rib net sheet 4, apply an amount of prestressing force, stretch out the horizontal bar of metope with the 4 binding colligations of vertical fine steel rib net sheet with horizontal thin muscle net sheet 2 again, and vertical fine steel rib net sheet 4 is anchored on the body of wall 1 the certain thickness high-grade cement mortar 3 of final powder with the anchor pin 5 of some.
Outside needs are provided with constructional column, see Fig. 4, Fig. 5, after treating that body of wall 1 binds, paste the wall face of body of wall 1, lay vertical fine steel rib net sheet 6, after applying an amount of prestressing force, vertical fine steel rib net sheet 6 is anchored on the body of wall 1, whitewashes to whitewash with high-grade cement mortar 3 at last and lump together with wall face with anchor pin 5.
Weak part in the house can be provided with the fine steel rib net sheet 7 of strengthening usefulness especially, and the colligation that is connected with vertical fine steel rib net sheet 6.
Maximum shear layer in the house is seen Fig. 6, and the vertical fine steel rib net sheet 4 of strengthening usefulness can be set especially, through stretch-draw, anchoring, and the colligation that is connected with the fine steel rib net sheet 2 of level, whitewash with high-grade cement mortar 3 at last.
Level, vertical, vertical size and the quantity that reaches the fine steel rib net sheet of strengthening usefulness, the diameter of steel bar stress and radical, according to local seismic fortification intensity, the number of plies in house and the Quality Design of building material and decide, general one collar tie beam established 2 two to three layers of horizontal thin reinforced mesh, lays one deck every 2-4 skin brick, vertical fine steel rib net sheet 4 and vertical fine steel rib net sheet 6, only paste the wall face setting, strengthen the fine steel rib net sheet 7 of usefulness, decide on the weak part in house.
Adopt the present invention to be provided fortification against earthquakes in the house of newly-built multi-story masonry load-bearing, theoretically, masonry house is made up of fragile material, and characteristics are that rigidity is big, flexible poor. Strengthen with collar tie beam, constructional column and weak part that prestressed fine reinforced mesh and brick setting are combined into, can improve fragility, increase ductility. The present invention can be generalized to the job site to advanced person's prestressing force technology, can save steel, cement, without shuttering, also need not on-the-spot pouring concrete, and reduce a large amount of on-the-spot water operations, can shorten the construction cycle again, certain society and economic benefit are arranged.
