Description
Technical Field
The invention relates to the field of buildings, in particular to a PEC beam-column connection node based on a high-performance cement-based material.
Background
The connection method of the PEC structure nodes in the prior art is as follows, firstly, the steel nodes in the PEC structure are bolted on site, and then concrete is poured on the steel nodes to complete the connection of the PEC structure nodes. However, the existing cast concrete aggregate is thick and poor in fluidity, so that the shell is easy to clamp during casting, vibration is needed, and the construction is troublesome; meanwhile, when the pouring template is installed, the template is not tightly sealed with the original PEC structure node, cement-based slurry is easily separated out from the gap during pouring, and concrete in the steel structure node is not fully poured due to the two reasons, so that obvious gap can be formed among the concrete poured in the node, the existing concrete and the upper flange of the steel beam.
And need 2 to 3 people's cooperation completions when installing the pouring mould in the node, it is comparatively troublesome to install.
In view of the above problems, the present invention provides a PEC beam-column connected node based on a high-performance cement-based material, and the present invention is made accordingly.
Disclosure of Invention
The invention provides a PEC beam-column connection node based on a high-performance cement-based material, which has the characteristics of simple and convenient template installation, compact poured concrete and tight connection with an original structure; specifically, the invention is realized by the following technical scheme:
a PEC beam-column connected node based on a high-performance cement-based material comprises a PEC beam and a PEC column which are vertically connected; after the PEC beam and the PEC column are connected, a cavity is defined by the PEC beam and the PEC column, the cavity comprises a top wall plate, a bottom wall plate and three side wall plates, one side face of the cavity is not provided with the side wall plate, and the side face is provided with an opening of the cavity; the cavity is filled with high-performance cement-based materials; a template covers the opening of the cavity, and double-sided foam adhesive tapes are adhered between the template and the contact part of two side wall plates of the cavity and the contact part of the template and the bottom wall plate; a gap is formed between the template and the top wall plate of the cavity; the template is provided with a detachable clamp, and the clamp applies clamping force to the template.
Further, a keel is arranged between the clamp and the template, the keel is in a strip shape, and clamping force on the clamp is uniformly dispersed and transmitted to the template.
Furthermore, the high-performance cement-based material adopts fine aggregate.
The beneficial effect of this application lies in:
the double-sided foam adhesive tape is arranged between the cavity in the PEC beam-column connection node and the template, so that the PEC beam-column connection node is connected with the template, no gap is formed at the left bottom and the right bottom between the PEC beam-column connection node and the template, and when a high-performance cement-based material is poured, the high-performance cement-based material cannot be separated out from the gap, so that the PEC beam-column connection node is poured compactly. Meanwhile, the pouring condition of the node can be observed through a gap between the template and the top wall plate of the cavity, and the occurrence of the condition that a gap occurs between a high-performance cement-based material poured later and an original structure at the top of the node is further avoided.
Adopt high performance cement-based material as the material of pouring the node, this high performance cement-based material has high strength, little inflation, high mobility's characteristics, and this high performance cement-based material adopts fine aggregate, consequently comparatively compactedly when filling so need not the vibration when pouring, can not appear blocking the shell, can not appear pouring incompact circumstances yet for the work progress is comparatively simple and convenient, and construction quality has also obtained the assurance simultaneously.
Because paste through the double faced adhesive tape between template and the node, can accomplish alone when the installation template, need not many people and assist, consequently the construction installation is comparatively convenient.
Through installing the fossil fragments between template and anchor clamps, can evenly transmit the clamp force of anchor clamps to the template on, the pouring structure mechanical properties of the node after the shaping is stable.

Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 3 and 4, a PEC beam-column connection node based on a high-performance cement-based material comprises a PEC beam 1 and a PEC column 2 which are vertically connected; after the PEC beam 1 and the PEC column 2 are connected, a cavity 3 is defined by the PEC beam 1 and the PEC column 2, the cavity 3 comprises a top wall plate 4, a bottom wall plate 5 and three side wall plates 6, the side wall plates 6 are not arranged on one side surface of the cavity 3, and the side surface is provided with an opening 8 of the cavity 3; the high-performance cement-based material is filled into the cavity 3 through the opening 8, the high-performance cement-based material has the characteristics of high strength, micro-expansion and high fluidity, and the high-performance cement-based material adopts fine aggregate, so that the high-performance cement-based material is compact during filling.
Covering a template 9 on the outer surface of an opening 8 of the cavity 3, adhering double-sided foam adhesive tapes 10 at the contact positions of the template 9 and the side ends of two side wall plates 6 which surround the cavity 3 and the contact positions of the template 9 and the side end of a bottom wall plate 5 of the cavity 3, and realizing the primary connection of the template 9 and the PEC beam 1 by the double-sided foam adhesive tapes 10; a double-sided foam adhesive tape 10 is not arranged between the template 9 and the side end of the top wall plate 4 of the cavity 3, so that a gap is formed between the template 9 and the top wall plate 4 of the cavity 3; because the gap is positioned at the top of the cavity 3, whether the cavity 3 is filled with the high-performance cement-based material or not can be observed through the gap as an observation port, if the cavity 3 is filled with the high-performance cement-based material, the high-performance cement-based material overflows from the gap, and if the gap is not filled with the high-performance cement-based material, the cavity 3 is not filled with the high-performance cement-based material, and the cavity 3 needs to be filled with the high-performance cement-based material continuously.
As shown in fig. 1 and 2, a detachable clamp 7 is provided on the template 9, and the clamp 7 applies a clamping force to the template 9, thereby closely fitting the template 9 to the cavity 3. The template 9 is sealed with the bottom and the side of the cavity 3, and the high-performance cement-based material cannot flow out from the left and the right sides and the bottom of the cavity 3.
In order to enable the clamping force on the clamp 7 to be uniformly transmitted to the template 9, a keel is arranged between the clamp 7 and the template 9, is in a strip shape, and can uniformly disperse the clamping force on the clamp 7 to be transmitted to the template 9.
Through template 9, fossil fragments, anchor clamps 7, can tightly pack high performance cement-based material in cavity 3, cavity 3 is closely knit completely, and the high performance cement-based material that back was poured is closely knit with PEC roof beam 1 and PEC post 2 material pouring, the separation can not appear, has guaranteed overall structure's intensity.
The above is the preferred embodiment of the present invention, and several other simple substitutions and modifications made on the premise of the inventive concept should be considered as falling into the protection scope of the present invention.
