A beam-column node steel reinforcement structure

Abstract

The utility model belongs to the technical field of building construction, and particularly relates to a beam-column node steel reinforcement structure, including a fixed column, and an I-beam installed on the fixed column docking node, and a support kit for connecting the I-beam is installed on the fixed column docking node. The elastic pleated airbag that expands when squeezed in the beam-column node steel reinforcement structure of the utility model can only expand and extend laterally, so that it can quickly fill the gap between the insertion cavity and the web of the I-beam, thereby greatly improving the tightness of the I-beam installation. At the same time, because the expanded elastic pleated airbag is an elastic structure, when the I-beam is subjected to a lateral impact force, the elastic pleated airbag can reduce the impact force on other docking I-beams on the fixed column node in terms of structural form, further improving the stability of the I-beam installation.

Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and particularly relates to a beam-column node steel reinforcement structure. Background Art

[0002] The frame structure is the most widely used form of building structure and the most common form of prefabricated and assembled structure. The prefabricated and assembled frame structure mainly includes two types: prefabricated concrete frame structure and steel frame structure. The connection structure of the prefabricated concrete frame structure is relatively complex, the integrity of the structure is poor, and its seismic performance needs further discussion; the steel frame structure can be connected by welding and bolts, with fast construction speed and good seismic performance, but poor corrosion resistance and high cost, poor economic benefits, and the use of prefabricated steel concrete frame structure is an effective way to solve the above contradictions. Therefore, domestic and foreign countries have begun to conduct certain research on prefabricated steel concrete frame structures, achieved corresponding results, and proposed a prefabricated steel concrete frame structure system. The existing prefabricated steel concrete frame structure system includes prefabricated steel concrete columns and steel beams. The difficulty in the design and construction of the prefabricated steel concrete frame structure system lies in the node core area where the two are connected. The node is the key part connecting the beam and the column. The internal force of the beam and the column is transmitted through the node. The safety and reliability of the node is the prerequisite for ensuring the safe operation of the structure.

[0003] The existing steel reinforced structure of the steel-concrete beam-column node cannot be easily assembled. When any of the I-beams connected around the beam and column is subjected to impact force, the other I-beams will be subjected to different degrees of impact, which will easily cause the connection between the beam and column and the I-beam to fail over a long period of time. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a beam-column node steel reinforcement structure which can measure the cutting length and save time and effort.

[0005] The beam-column node steel reinforcement structure designed in the utility model includes:

[0006] Fixed columns, and

[0007] An I-beam installed on the fixed column docking node, and a support kit for connecting the I-beam is installed on the fixed column docking node;

[0008] The support kit includes an insertion plate, which is fixedly welded on a node of a fixed column, and an insertion cavity is provided on the insertion plate. The inner walls of the insertion plate on both sides of the insertion cavity are provided with installation grooves, and elastic pleated airbags are installed in the two installation grooves in the insertion plate, and a pressing plate is installed on the end face of the elastic pleated airbag away from the fixed column.

[0009] Preferably, two pressing plates symmetrically distributed up and down are installed on the end surface of the elastic pleated airbag away from the fixed column, and the abutting plate surfaces of the two pressing plates respectively pass through the two installation grooves opened in the plug-in plate and extend out of the plug-in plate.

[0010] Preferably, the bag wall of the elastic pleated airbag close to the fixed column is fixedly connected to the inner groove wall of the insertion plate.

[0011] Preferably, two symmetrically distributed side panels are fixedly mounted on the inserted end of the I-beam, and each of the side panels is provided with a waist-shaped mounting hole.

[0012] Preferably, the end surface of the fixed column docking node is provided with a waist-shaped pulling hole, and the waist-shaped pulling holes on the adjacent two side walls of the fixed column are staggered.

[0013] Preferably, the I-beam is inserted into an insertion cavity provided in an insertion plate.

[0014] Preferably, the I-beams on the opposite side walls of the fixed column are fixedly connected by drawing rods, and the drawing rods are provided with fastening nuts.

[0015] Compared with the related art, the beam-column node steel reinforcement structure provided by the utility model has the following beneficial effects:

[0016] The utility model inserts the web of one end of the I-beam installed with the side plate into the insertion cavity opened in the insertion plate, and the upper and lower wing plates of the I-beam abut against the abutment plate surface of the corresponding pressing plate when sliding along the inner side of the insertion plate. Therefore, the elastic pleated airbag expanded by being squeezed can only extend and expand laterally, so that it can quickly fill the gap between the insertion cavity and the web of the I-beam, thereby greatly improving the tightness of the installation of the I-beam. At the same time, because the expanded elastic pleated airbag is an elastic structure, when the I-beam is subjected to a lateral impact force, the elastic pleated airbag can structurally reduce the impact force on other connected I-beams on the fixed column node, thereby further improving the stability of the installation of the I-beam.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 4 An embodiment of the utility model provides a beam-column node steel reinforcement structure, and the beam-column node steel reinforcement structure includes: a fixed column 1, a support kit 2 and an I-beam beam 3.

[0025] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The fixed column 1 has an I-beam 3 installed on the docking node, and the fixed column 1 has a support kit 2 for connecting the I-beam 3 installed on the docking node, and the support kit 2 includes a plug-in plate 21, the plug-in plate 21 is fixedly welded on the node of the fixed column 1, and the plug-in plate 21 is provided with a plug-in cavity 21a, and the inner wall of the plug-in plate 21 on both sides of the plug-in cavity 21a is provided with installation grooves 21b, and the two installation grooves 21b in the plug-in plate 21 are installed There is an elastic pleated airbag 22, the bag wall of the elastic pleated airbag 22 close to the fixed column 1 is fixedly connected to the inner groove wall of the insertion plate 21, and the end face of the elastic pleated airbag 22 away from the fixed column 1 is installed with a pressing plate 23. Specifically, the end face of the elastic pleated airbag 22 away from the fixed column 1 is installed with two pressing plates 23 symmetrically distributed up and down, and the abutting plate surfaces of the two pressing plates 23 respectively pass through the two installation grooves 21b opened in the insertion plate 21 and extend out of the insertion plate 21.

[0026] It should be noted that: when installing the I-beam 3 on the node of the fixed column 1, the web of one end of the I-beam 3 with the side plate 31 installed is inserted into the insertion cavity 21a opened by the insertion plate 21, and the upper and lower wing plates of the I-beam 3 slide along the insertion plate 21 and abut against the corresponding abutment plate surface of the pressing plate 23, so the elastic pleated airbag 22 is squeezed by the pressing plate 23 and expands. Since the front and rear end surfaces of the elastic pleated airbag 22 and the outer wall of the elastic pleated airbag 22 are squeezed by the pressing plate 23 and the inner groove wall of the installation groove 21b, Restriction, therefore the elastic pleated airbag 22 that is squeezed and expanded can only extend and expand laterally, so that it can quickly fill the gap between the insertion cavity 21a and the web of the I-beam 3, thereby greatly improving the tightness of the installation of the I-beam 3. At the same time, since the expanded elastic pleated airbag 22 is an elastic structure, when the I-beam 3 is subjected to a lateral impact force, the elastic pleated airbag 22 can structurally reduce the impact force on other connected I-beams 3 on the node of the fixed column 1, thereby further improving the stability of the installation of the I-beam 3.

[0027] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The insertion end of the I-beam 3 is fixedly installed with two symmetrically distributed side panels 31, and each of the side panels 31 is provided with a waist-shaped mounting hole 31a, and the end face of the docking node of the fixed column 1 is provided with a waist-shaped pulling hole 1a, and the waist-shaped pulling holes 1a on the adjacent two side walls of the fixed column 1 are staggered, and the I-beam 3 is inserted into the insertion cavity 21a opened in the insertion plate 21, and the I-beam 3 on the opposite two side walls of the fixed column 1 is fixedly connected by a pulling rod 4, and a fastening nut is installed on the pulling rod 4.

[0028] It should be noted that: when the side plates 31 on both sides of the I-beam 3 are in contact with the node of the fixed column 1, the drawing rod 4 is passed through in sequence: the waist-shaped mounting hole 31a opened on the side plate 31 of the I-beam 3 → the waist-shaped pulling hole 1a opened on the fixed column 1 → the waist-shaped mounting hole 31a opened on the side plate 31 of the other side of the I-beam 3, and then fixed with nuts.

[0029] The working principle of the beam-column node steel reinforcement structure provided by the utility model is as follows:

[0030] When installing the I-beam 3 on the node of the fixed column 1, the web of one end of the I-beam 3 installed with the side plate 31 is inserted into the insertion cavity 21a opened in the insertion plate 21, and the upper and lower wing plates of the I-beam 3 slide along the insertion plate 21 and abut against the abutting plate surface of the corresponding pressing plate 23, so that the elastic pleated airbag 22 is squeezed and expanded by the pressing plate 23. Since the front and rear end surfaces of the elastic pleated airbag 22 and the outer bag wall of the elastic pleated airbag 22 are restricted by the pressing plate 23 and the inner groove wall of the installation groove 21b, the elastic pleated airbag 22 that is squeezed and expanded can only extend and expand laterally, so that it can fill the airbag quickly. The gap between the filling cavity 21a and the web of the I-beam 3 is filled, thereby greatly improving the tightness of the installation of the I-beam 3. At the same time, since the expanded elastic pleated airbag 22 is an elastic structure, when the I-beam 3 is subjected to a lateral impact force, the elastic pleated airbag 22 can structurally reduce the impact force on other connected I-beams 3 at the node of the fixed column 1, thereby further improving the stability of the installation of the I-beam 3. When the side plates 31 on both sides of the I-beam 3 are fitted onto the node of the fixed column 1, the drawing rod 4 is inserted to pass through the side plate 31 of the I-beam 3 at the other end, and then fixed with a nut.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
