Abstract
The utility model discloses a ring beam structure newly arranged at the bottom of a construction floorslab. A ring beam (5) is arranged at the connection position between a wall body (1) of a building and a floorslab (2), at the bottom of the floorslab (2) and along the wall body (1). The ring beam (5) is connected with the floorslab (2) through fillings inside more than two pouring troughs (3) arranged in one row. A clumpy decoration layer (4) which can cover the pouring troughs (3) is arranged on the upper portion of the floorslab (2). According to the ring beam structure newly arranged at the bottom of the construction floorslab, by newly arranging the ring beam on the bottom of the construction floorslab, the anti-seismic property of the original building is strengthened and improved. The problem that time and efforts are wasted when a ring beam is additionally arranged on the bottom of an original floorslab is resolved. The strengthening effect is improved obviously. Due to the fact that the new strengthening component can be connected with the original building closely and can be stressed together with the original building, the problem of stress lagging is resolved. Through the method that grooves are arranged in the floorslab and steel bars are arranged in the grooves, the construction problem that concrete is not easy to be cast in the ring beam additionally arranged on the bottom of the original floorslab is resolved. The traditional construction process is improved, efficiency is improved and cost is further reduced.
Description
Technical field
The utility model relates to a kind of collar tie beam structure of newly establishing in the building floor bottom, belongs to the extraordinary technical field of construction of building.
Background technology
Collar tie beam is around the skin and the beam of the continuous sealing that cross wall arranges in the part, its objective is for the integral rigidity that strengthens building and the stability of wall body.Collar tie beam can reduce gene basis differential settlement or larger vibration load to adverse effect and the caused wall body cracking thereof of building.In the area of providing fortification against earthquakes, utilize collar tie beam reinforcement walls body to seem more necessary.Reinforcing the anti-seismic performance that improves original building at the newly-increased collar tie beam of floor slab bottoms, is one technical barrier in the strengthening construction process.Because the young concrete collar tie beam is not only time-consuming at the bottom of the plate, and can not the fine while stressed with original structure.Adopt constructional materials, the construction quality of high-quality strictly to control in no matter constructing, all can not obtain good effect.Therefore practice is restricted, usually replaced by reinforcing pull rod, yet the performance of reinforcing pull rod is far away from reinforced concrete circle beam.
Why traditional construction technology is difficult for construction, poor effect, reason have following some:
At first, newly-increased concrete collar tie beam is difficult for building at the bottom of the plate, and common practices is: method one is after assembling reinforcement, staying the slit above the template and between the floor slab bottoms, chinky altitude is greater than the vibrating head diameter, through the slit in the template concreting, vibrate, artificial plug is filled out this top, slit more afterwards.Method two is after assembling reinforcement, and sidepiece stays " infundibulate " to build groove above template, through the slit in the template concreting, vibrate, manually after form removal reject unnecessary infundibulate concrete.Although these two kinds of methods can both be finished building of newly-increased concrete collar tie beam at the bottom of the plate, constructor's technical ability is had relatively high expectations, and when relatively taking a lot of work.
Secondly, adopt artificial stuff up a crack or reservation infundibulate groove mode to construct, newly-increased member closely is connected with original building, the common stressed effect of the old and new's member is not good, and stress lags behind, and affects consolidation effect.
Along with improving constantly of China's economic level, building aseismicity is required also more and more to pay attention to, especially in emphasis such as transforming old hospital, old teaching building is set up defences building, depend merely on reinforcing pull rod and can not satisfy shockproof requirements.Therefore need to consider a kind of construction measure that newly-increased concrete collar tie beam is reinforced at the bottom of plate, can not only significantly improve the house performance, can also improve conventional practice, raise the efficiency.
Summary of the invention
The purpose of this utility model is, a kind of collar tie beam structure of newly establishing in the building floor bottom is provided, and this structure can be combined with the original building close structure, improves consolidation effect, and is easy to construction.
The technical solution of the utility model: for realizing the purpose of this utility model, a kind of collar tie beam structure of newly establishing in the building floor bottom of the present utility model, comprise body of wall and floor, wherein, be positioned at floor slab bottoms in described body of wall and floor junction and be provided with collar tie beam along body of wall, collar tie beam links to each other with floor by the charges of building in the groove of layout in a row more than two, and arranges and can will build the decorative layer of the one-tenth piece of groove covering on floor top.
Further, the above-mentioned collar tie beam structure of newly establishing in the building floor bottom, wherein, the described groove of building is of a size of 200mm * 300mm.
Further, above-mentioned collar tie beam structure of newly establishing in the building floor bottom, wherein, described spacing of building between adjacent two of the groove is 600mm.
Further, the above-mentioned collar tie beam structure of newly establishing in the building floor bottom, wherein, described charges are pea gravel concreten or grouting material.
Again further, the above-mentioned collar tie beam structure of newly establishing in the building floor bottom wherein, is provided with steel fabric sheet or anti-crack fiber cloth in the described decorative layer.
Compared with prior art, collar tie beam structure of newly establishing in the building floor bottom of the present utility model is by reinforcing the anti-seismic performance that improves original building at the newly-increased collar tie beam of floor slab bottoms, increase time-consuming, the problem of taking a lot of work of collar tie beam newly at the bottom of solving conventional panels, and consolidation effect is significantly promoted, and new strenthening member and original building are combined closely, jointly stressed, solve stress and lag behind; Solve newly-increased plate foundation ring beam by plate internal recessing and the method that reinforcing bar is set and be difficult for the placing of concrete construction problem, improve traditional construction technology, raise the efficiency; Reduce irregular template materials amount and reinforce the rear unnecessary concrete recruitment amount of rejecting, reduce cost.Compare not only time and labour saving with conventional construction, and satisfy with original structure jointly stressed, the requirement of integrality performance of the structure enhancing.
