Description
Technical field
The utility model relates to construction appurtenances, and in particular to a kind of prefabricated big height difference of beam column can be recycled
Pre-buried bracing members.
Background technique
Prefabricated components are often used when construction, but how prefabricated components guarantee component during construction and installation
Stablize safety it is most important.Most important supporting member is overlapping contignation in prefabricated components, and superimposed sheet rides over the side of beam
Edge, beam rides over prefabricated post or shear wall edge, and prefabricated post has rod piece support, and scaffold is usually used in the support at precast beam bottom
Form.
Prefabricated beam column or precast beam shear wall connecting node are primarily present three problems:
First, the problem of the precast beam concrete lap of splice.Precast beam and prefabricated post and the shear wall structure lap of splice one
As be less than column shear wall protective layer thickness, overlap distance is shorter, and due to the scale error of component production, lifting component personnel
Operation is horizontal and the factors such as site operation environment, it is generally difficult to precisely smoothly complete overlap joint, generally require several personnel it is long when
Between cooperate for several times, adjustment could be completed repeatedly, while be difficult to ensure overlap joint quality.
Second, the rear pouring concrete problem at beam column or beam wall node.After precast beam overlaps prefabricated post, the side form in node area
What plate used is not Screw arbor with nut at both-ends but is carried out in batten mode using shuttering supporting, and batten support needs to follow closely in prefabricated post
The support of body, template will be sufficiently complex, and in the case where not can guarantee overlap joint quality, the support effect of end template will will receive shadow
It rings, and then influences beam column cast-in-place node concrete rigidity.
Third, the installation supported under precast beam and removes problem.It is prefabricated for the safety for guaranteeing prefabricated components work progress
The vertical supporting of beam is often very many and diverse, and a large amount of vertical supporting reduces the construction space of understructure.
Summary of the invention
It is poured after insufficient, node for the lap of splice at above-mentioned assembled beam-column node and supports installation under shuttering supporting and plate
The technical problems such as cumbersome are removed, the utility model provides a kind of pre-buried bracing members that can be recycled of big height difference of prefabricated beam column,
Bracing members are connected by the way that bolt to be embedded in prefabricated post in advance, then by nut, extends the lap of splice, there is good stress
Can, to meet the requirement of overlap joint precision.
The technical solution adopted in the utility model is:
Including channel steel, the wing plates on two sides of channel steel is respectively fixed with stiffened steel plates, the tops of stiffened steel plates and channel airfoil plate
Top level is fixedly connected with steel plate bracket, and the notch board inside middle portion of channel steel is equipped with nut, and nut stretches out outside channel steel, channel steel
The notch board back side in the middle part of and lower part be respectively arranged with steel cushion block.
Preferably, the length of steel plate bracket be greater than channel steel height (that is to say between two wing plate outer edge of channel steel away from
From).
Preferably, the steel cushion block of consistency of thickness, thickness and later period branch is respectively set in the middle part of the channel steel notch board back side and lower part
Template thickness it is identical, the purposes of steel cushion block is to give later period formwork supporting plate reserved space.It further, can be by upper and lower two steel pads
Block is set as length and width, thick all consistent square cushion block.Steel cushion block is as bean column node envelope mould support, both to bean column node envelope mould
It will not influence, can provide convenience instead.
Preferably, the cross section of stiffened steel plates is wide at the top and narrow at the bottom.Further, the front lower portion of stiffened steel plates can be arranged
For inclined-plane, the slope angle on inclined-plane is 65-70 degree.
The utility model has the advantages that structure is simple, prefabricated beam column and shear wall etc. can be made to reduce vertical supporting when overlapping,
The rigid support of the utility model is even only needed, and bracing members are Ke Xunhuanliyong, turnover is fast compared with the support of other rod piece formulas
And it is easy, concrete operations are also compared with rod piece simplicity.It can be according to the different bracing members for needing to make different height differences.

Specific embodiment
Embodiment 1
According to Fig. 1,2, symmetrical stiffened steel plates 2, stiffened steel plates are welded on two wing plates of the channel steel 4 of the present embodiment
2 top and the top level of 4 wing plate of channel steel are fixedly connected with steel plate bracket 1, and the length of steel plate bracket 1 is greater than the height of channel steel 4
Degree, inside is separately installed with four nuts 3 on the lower at the notch board middle part of channel steel 4, and two nuts 3 each above and below, nut 3 stretches out
Nut 3 is screwed into the bolt of prefabricated post respectively and is tightened in use, being embedded with bolt in prefabricated post 6 by the outside of channel steel 4.Slot
In the middle part of the notch board back side of steel 4 and lower part is respectively arranged with steel cushion block 5, and in the present embodiment, upper and lower two pieces of steel cushion blocks 5 are rectangular
Body, length is consistent, and the side edge line of cuboid is in same vertical line.The cross section of stiffened steel plates 2 is under upper width
Narrow irregular pentagon, the front lower portion of stiffened steel plates 2 are set as inclined-plane, and slope angle is 65 degree.
Fig. 3 shows the use state of the present embodiment bracing members, and nut 3 is screwed into bolt pre-buried in prefabricated post 6, steel plate
Bracket 1 is close to prefabricated Cantilever Beams 7, just holds prefabricated Cantilever Beams 7.When prefabricated post 6 is different with the height difference of prefabricated Cantilever Beams 7
When, the bracing members of different height differences can be used.
