Description

A kind of precast beam structure
Technical field
The present invention relates to technical field of building construction, more particularly to a kind of precast beam structure.
Background technology
In the realm of building construction, building prefabricated components are general first in factory's concentration pre-casting production, then transport to job site Installed, improve construction speed, reduced artificial input, save construction cost.But current precast beam and prefabricated post Common installation form be the beam one of two post one across form, when job site needs to install a large amount of precast beams, precast beam can only be single Branch is lifted, for skyscraper, and tower crane lifting number of times increase, lifting efficiency reduction, engineering time cost is higher.
The content of the invention
It is an object of the invention to provide a kind of precast beam structure, the precast beam is connected two beam bodies by lower floor's cage bar Through an entirety is connected as, solve job site lifting often, the problem of efficiency is low, the cycle is long.
For up to this purpose, the present invention uses following technical scheme:
A kind of precast beam structure, including the first beam body and the second beam body, first beam body and the second beam body are along length side To axis be located along the same line, first beam body and the second beam body are connected by lower floor's cage bar, and lower floor's cage bar is equal First beam body is sequentially passed through along its length and the second beam body is set.
Lower floor's cage bar through the first beam body and the second beam body is arranged by Mechanics Calculation, two beam bodies are connected as one It is overall, at the construction field (site) by a lifting operation just can realize with the prefabricated post formation beam two of three post two across mounting structure, section Lifting number of times is saved, accelerates lifting progress, shortens whole construction period.
Further, first beam body and the second beam body are arranged at intervals.When being installed with prefabricated post, compartment overlap joint In the beam two of three post two across in prefabricated post centrally located in this mounting structure.
Further, first beam body and the second beam body are respectively stretched out in the two ends of lower floor's cage bar.Lower floor's cage bar Two ends extension is overlapped on the beam two of three post two across being located in this mounting structure in the prefabricated post of both sides, reaches that Bar Anchorage is long Degree is required.
Further, the extension of lower floor's cage bar is L-shaped or " one " font.Its concrete form is according to different Installation needs to be chosen.
Further, first beam body and the second beam body are embedded with some stirrups along its length.Stirrup point encrypted area Set with non-encrypted area, stirrup is used for fixing the position of lower floor's cage bar, prevent in follow-up concreting lower floor's cage bar by Extrude and deform, shift, moreover it is possible to good framework of steel reinforcement is formed together with the various reinforcing bars in precast beam structure, improve precast beam The compression strength of structure.
Further, the stirrup is open rectangle stirrup, enclosing square stirrup or groined type stirrup etc., its concrete form Select according to actual needs.
Compared with prior art, advantages of the present invention and have the beneficial effect that:The precast beam structure of the present invention passes through lower floor master First beam body and the second beam body are connected as an entirety, for construction site is especially for skyscraper, tower by muscle Lift up into lifting operation of row just can realize the beam two of three post two across mounting structure, save lifting number of times, accelerate lift into Degree, improves lifting efficiency, shortens construction period.

Embodiment
For make present invention solves the technical problem that, the technical scheme that uses and the technique effect that reaches it is clearer, below Technical scheme is further illustrated with reference to accompanying drawing and by embodiment.
The present embodiment provides a kind of precast beam structure 1, as shown in figure 1, the precast beam structure 1 includes the first beam body 11 and the Two beam bodies 12, axis of first beam body 11 with the second beam body 12 along its length is located along the same line and structure is identical, Two beam bodies are arranged at intervals and by lower floor's cage bar 13 through being connected to become an entirety, lower floor's cage bar 13 along its length according to Secondary to run through the first beam body 11 and the second beam body 12 is set, the first beam body 11 and the second beam body are stretched out in the two ends of lower floor's cage bar 13 respectively 12, extension is L-shaped or " one " font structure, to reach the requirement of bar construction anchorage length.By in the first beam body 11 Lower floor's cage bar 13 is set with running through in the second beam body 12, two beam bodies are connected to become an entirety, so constructed at the scene When, tower crane is once lifted just can be stretched while sling two beam bodies by the compartment in the middle of two beam bodies and two ends The reinforcing bar part gone out is installed in three prefabricated posts 2, formed therewith the beam two of three post two across mounting structure, as shown in Fig. 2 so as to Saving lifting number of times is reached, accelerates lifting progress, improves efficiency of construction, shorten the purpose of construction period.It is understood that under The radical of layer cage bar 13 and the structure type of stretching beam body part can be determined according to specific construction requirement, in the present embodiment In, the radical of lower floor's cage bar 13 is chosen for two, and the part that lower floor's cage bar 13 stretches out beam body two ends is in " one " font structure.
Further, lower floor's cage bar 13 is located at the bottom of the first beam body 11 and the second beam body 12 in the present embodiment, prefabricated Beam is primarily subjected to bending load, is embedded in lower floor's cage bar 13 therein and plays structural effect, is disposed at beam body bottom, energy Preferably bear bending load.
Further, the first beam body 11 and the second beam body 12 are disposed with some stirrups by structural requirement along its length (not shown), specifically, stirrup point encrypted area and non-encrypted area are set.Stirrup is used for bearing shearing force and fixed lower floor master The position of muscle 13, prevents that lower floor's cage bar 13 is squeezed and deformed, shifts in follow-up concreting, moreover it is possible to precast beam knot Various reinforcing bars in structure 1 form good framework of steel reinforcement together, improve the compression strength of precast beam structure 1.Encrypted area and Fei Jia Mi Qu setting form ensure that precast beam structure 1 meets structural requirement.Above-mentioned stirrup can be open rectangle stirrup, closing Rectangle hoop or groined type stirrup etc., preferred open rectangle stirrup in the present embodiment.
The precast beam structure 1 that the present invention is provided is applied to pure frame structure, is built in the large-scale room such as utilities building supermarket Using efficiency of construction can be significantly improved in structure, construction cost is reduced, such as being promoted the use of in building field certainly will can obtain aobvious The economic benefit of work.
Obviously, the above embodiment of the present invention is just for the sake of clear explanation example of the present invention, and is not pair The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.It is all this Any modifications, equivalent substitutions and improvements made within the spirit and principle of invention etc., should be included in the claims in the present invention Protection domain within.
