Description
Technical field
To boost sales after the present invention relates to the prefabricated circular hole slab of a kind of existing building the dark seismic strengthening of beams method of key, belong to technical field of anti-seismic reinforcement.
Background technology
At present, whole nation existing apartment, hospital, the seismic hardening of agriculture residence starts to start, existing apartment or plate end not enough with the agriculture residence a large amount of masonry structure circular hole slab bearing length before 2000 is connected that measure is not in place does not meet current seismic design reinforcement specification before the eighties in last century, have a strong impact on its anti-seismic performance, the a lot of earthquake disaster of China shows in recent years, masonry structure floor comes off to cause injury and lethally in this class formation earthquake, account for larger specific gravity, floor comes off effective strong point that caused body of wall to lack, anti-seismic performance sharply declines, integral house local or entirety are collapsed instantaneously, strengthening effective connection and shelving length between precast floor slab reinforces particularly important for Hollow Block Masonry Structure Anti-seismic.The method that traditional design adopts angle steel to support is during construction reinforcement, and the common people are unwilling to allow construction of registering one's residence, and also has the impact of the angle steel of bright dew attractive in appearance, in addition difficulty of construction comparatively greatly, long to resident family's influence time, cost is high.Each R&D institution not yet takes out way effectively and solves this thing.
Summary of the invention
In order to overcome the problems referred to above, to boost sales after the present invention proposes the prefabricated circular hole slab of a kind of existing building the dark seismic strengthening of beams method of key, it is without the need to destroying appearance and interior decoration, whole external procedure forms new antidetonation rod member, significantly can improve the anti-seismic performance of existing building, solve the not enough problem of Seismic Bearing Capacity.
Technical scheme of the present invention is as follows:
To boost sales after the prefabricated circular hole slab of a kind of existing building the dark seismic strengthening of beams method of key, comprise former prefabricated circular hole slab and former masonry panel, described former prefabricated circular hole slab is provided with multiple plate hole, on the former masonry panel of described former at least one plate hole end of prefabricated circular hole slab, plate hole length direction is provided with horizontal drilling, the plate hole level that horizontal drilling on described former masonry panel is corresponding with on former prefabricated circular hole slab is through to be integrated, reinforcing bar or steel strand are equipped with in described horizontal drilling and corresponding plate hole, polymer mortar is perfused with in horizontal drilling and corresponding plate hole, to boost sales after the polymer mortar of the reinforcing bar in described horizontal drilling or steel strand and perfusion forms floor key, and the polymer mortar of reinforcing bar in former prefabricated circular hole slab plate hole or steel strand and perfusion increases dark beam after forming floor, described method adopts following steps:
Step one: by identifying existing building, detect former prefabricated circular hole slab plate hole locations, and in the enterprising row labels of former masonry panel, determine the polymer mortar intensity needing the format diameter of the aperture location of horizontal drilling, reinforcing bar or steel strand and inside to pour into through design;
Step 2: according to construction drawing determination horizontal drilling distance, and then select rig to prepare to carry out horizontal drilling, set up scaffold and erection construction platform;
Step 3: fix rig on operation platform, successively horizontal drilling construction operation is carried out to former masonry panel from the bottom to top, after horizontal drilling, whether the plate hole diameter corresponding with on former prefabricated circular hole slab conforms in detection level boring, if continue the former crack pouring concrete that penetrates between two pieces of former prefabricated circular hole slabs on former masonry panel interior wall of holing after conforming to, hole and completely hole is cleaned out and penetrate reinforcing bar or steel strand in horizontal drilling and corresponding plate hole;
Step 4: stand placed in the middle by reinforcing bar or steel strand frame, changes high-pressure slip-casting equipment and prepares to pour into polymer mortar;
Step 5: by horizontal drilling and corresponding plate hole through after hole sealing two ends, grouting equipment is adopted to pour into polymer mortar in horizontal drilling and corresponding plate hole, not spillage should be noted during level perfusion polymer mortar, by grouting port shutoff after perfusion polymer mortar, and namely through outside horizontal drilling after hole two ends anchor bolt is installed reinforcing bar or steel strand is fixed;
Step 6: the structure after construction reinforcement is carried out an acceptance inspection.
Further, increasing dark beam after the floor arranged in described former prefabricated circular hole slab is two, and key of boosting sales after the floor of its correspondence is also two.
Further, increase dark beam after two floors arranged in described former prefabricated circular hole slab to be symmetrical arranged along former prefabricated circular hole slab horizontal cross.
Further, described reinforcing bar or steel strand are positioned at horizontal drilling and corresponding plate hole center position.
Further, the connection between described reinforcing bar adopts overlap joint or welding.
Further, on described former masonry panel, the diameter of horizontal drilling is identical with the plate hole diameter on former prefabricated circular hole slab.
Wherein, polymer mortar adopts high-pressure injection pump to inject, and need in hole full, polymer mortar intensity is chosen according to design.Key of boosting sales after floor is the reinforced concrete member formed after polymer injection mortar, belongs to structure rod member, and reinforcing bar or steel strand model and required polymer mortar intensity are as the criterion to increase dark beam design determined value after floor.Increasing dark beam after floor is the steel concrete stressed member formed after polymer injection mortar, and arrangement of reinforcement is determined according to design.
Beneficial effect:
Key of boosting sales after floor of the present invention improves the switching performance between plate, compensate for the not enough deficiency with lacking effective drawknot each other of prefabricated circular hole slab shelving length; Increase the rod member of dark beam form floor in the middle part of plate after, improve the bearing capacity of prefabricated circular hole slab.Meanwhile, the present invention fully incorporates the advanced single technology of conglomerate in recent years, and each single technology is ripe, and speed of application is fast, small investment, the present invention do not register one's residence realize the larger raising of Seismic Behavior of Masonry and, construction is simple, and cost is low.The present invention has wide range of applications and is applicable to the prefabricated circular hole slab superstructure of all existing buildings, roof system, has higher economic benefit and social benefit.
