Abstract
The utility model discloses a cast-in-place concrete hollow beam-free floor thin wall hollow-pipe fixed structure. Steel bars of floor slabs are provided with plurality groups of two-row steel bar net slices which are mutually matched, the mutually matching steel bar net slices are both provided with partition walls which can be exactly arranged in a thin-wall hollow pipe; the steel bar net slices are fixed to the floor slab steel bar, the steel bar net slices are fixed to the supporting framework of the floor slab by passing through the floor slab with ropes. Compared to the traditional location method, this technique has the advantages of ensuing project quality, saving cost, shortening construction period, and good technical economic effect.
Description
Technical field
The utility model belongs to the structure that is used for fixing thin-wall hollow pipe in the construction of cast-in-place concrete hollow arch without beam, is specifically related to the installation and the fixed structure of thin-wall hollow pipe.
Background technology
In recent years, hollow girderless floor in cast-in-place concrete extensively should be in large space, large tracts of land, do not need in the middle of all kinds of engineerings of furred ceiling, this key problem in technology is the formation of structure hollow parts, it is different from the formation of loosing core of precast hollow slab, but adopt the pre-buried form of fixedly doing permanent mandrel of the hollow short tube of end socket, hollow short tube is the high-strength thin-wall pipe that adopts extraordinary tube-making process principle to make, and this hollow short tube abbreviates the GBF pipe as.The GBF pipe is positioned over the middle part of floor levels reinforcing bar, and placing of concrete under the situation of pipe in not taking out, pre-buried hollow section have played the effect of the inner template of cast-in-situ concrete.
Because the deadweight of GBF pipe itself is very light, the buoyancy that produces during concrete vibrating is easy to and the GBF pipe can be come together with steel mesh reinforcement jack-up, makes the GBF pipe produce come-up and offset phenomena, and the tram that therefore how to guarantee the GBF pipe becomes the key point in the construction.At present, adopt by pipe of the location of GBF pipe tied up methods such as adding wedge between bundle, pipe more in the floor, and this kind method not only operation is numerous and diverse, and is long in time limit, and very easily because of operating the workmanship hidden danger that causes out of control, can't fundamentally solve the correct orientation problem of GBF pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and practical cast-in-place concrete hollow arch without beam thin-walled hollow pipe fixation structure, this structure can solve problems such as thin-wall hollow pipe come-up and displacement for addressing the above problem.
For the utility model that achieves the above object is a kind of cast-in-place concrete hollow arch without beam thin-walled hollow pipe fixation structure of realizing like this, floor bar is provided with some groups of two placing of reinforcement net sheets in correspondence with each other, and this corresponding reinforced mesh all is provided with the partition that thin-wall hollow pipe can just be placed; Described reinforced mesh and floor bar are fixed, and this reinforced mesh is reeved the support frame that floor is fixed in floor.
Optimally, the distance between the two placing of reinforcement net sheets of above-mentioned correspondence is according to the length setting of thin-wall hollow pipe.
Optimally, reinforced mesh and floor bar are tied up fixing; The stationary rope of reinforced mesh passes floor and ties up the support frame that is fixed in floor.
Advantage and good effect that the utility model had are: present technique is compared with traditional localization method, can guarantee workmanship, saves cost, the reduction of erection time, has good technology economic.
1. technical elements
1.1 accurate positioning.Reinforced mesh is enclosed within cement thin-walled hollow section two ends, with the colligation of floor structure levels structure reinforcing bars fixing after, can control level, vertical displacement that cement thin-walled hollow section (GBF) does not produce effectively in the concrete pouring construction process, guarantee the concrete structure quality.
1.2 reinforcing bar network for location sheet, the location split heads of double as floor levels structure reinforcing bars, both economical and practical, can make full use of concrete structure deadweight etc. again, offset all or part of buoyancy and horizontal thrust.Thus can be not if establish the anti-come-up iron wire drawknot of light-wall pipe less, save numerous and diverse anti-pore-forming pipe level, the measure of vertical displacement.
But 1.3 the reinforced mesh field fabrication, but factory process, netting length is looked the quantity of fixing pipe of cement, and what are changeable, are beneficial to execute-in-place.
2. economic aspect
Adopting the present technique construction cost only is 31% of conventional wedge bindings bit method, the reduction of erection time 50%.Saved a large amount of maintenance cost of later stage simultaneously.
Below in conjunction with Figure of description the utility model is done further to disclose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of cast-in-place concrete hollow arch without beam thin-walled hollow pipe fixation structure, floor bar 1 is provided with some groups of two placing of reinforcement net sheets 2 in correspondence with each other, length between this corresponding reinforced mesh 2 is according to the length setting of thin-wall hollow pipe 4, their required distance slightly is shorter than the length of thin-wall hollow pipe 4, suitable thin-wall hollow pipe 4 places the both sides, back respectively has one section to exceed, and is convenient to fix.Reinforced mesh 2 all is provided with the partition 3 that thin-wall hollow pipe 4 can just be placed; This cuts off the 3 size settings according to thin-wall hollow pipe 4, makes its whole dimension slightly exceed thin-wall hollow pipe 4 and gets final product.
Reinforced mesh 2 is tied up fixing with floor bar 1 employing.The stationary rope of this reinforced mesh 1 also passes floor 6 and ties up the support frame 5 that is fixed in floor.
This cast-in-place concrete hollow arch without beam thin-walled hollow pipe fixation structure uses the technological process of back cast-in-situ concrete as follows:
Muscle initial test → layings GBF pipe → floor top reinforcement colligation → line → watering is led in the adjustment of GBF pipe, and water seasoning is built → covered to moistening → hidden examination → concrete at the bottom of the muscle colligation at the bottom of location unwrapping wire → dark beam steel colligation → floor → laying typing processing reinforcing bar position-limited rack → mounting pipe wire routing → dark beam and plate.
