Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly relates to a building structure connection node. Background Art

[0002] A connection node is a part where components such as beams, columns, slabs, and walls in a building structure meet, ensuring the coordinated work of the structure under the action of loads and transmitting internal forces. Among them, a double-sided arc-shaped pressure bearing support node is provided with a double-sided arc-shaped steel casting with arc-shaped surfaces on both the upper and lower sides between the upper support plate of the grid support and the lower support bottom plate of the support. The double-sided arc-shaped steel casting adopts an I-shaped cross-section and is provided with a through hole at the center. The axes of the upper and lower arc-shaped surfaces and the axis of the through hole should fall in the same vertical plane, and the axis of the upper arc-shaped surface is below the axis of the through hole, and the axis of the lower arc-shaped surface is above the axis of the through hole, so as to form a cam blocking effect on the deflection or displacement of the upper support plate or the lower support bottom plate after a certain deflection or displacement of the upper support plate or the lower support bottom plate relative to the double-sided arc-shaped steel casting.

[0003] Trapezoidal connecting plates with elliptical holes are welded on both the upper support plate of the support and the lower support bottom plate on both sides of the double-sided arc-shaped steel casting, and bolts are used to pass through the elliptical holes and the through holes to connect the three into a whole. The elliptical holes are used for the upper support plate of the grid support to rotate and translate along the arc-shaped surface of the steel casting when the grid is affected by stress, so that the bolts slide in the elliptical holes to release stress. However, when the stress causes the upper support plate of the support to tilt, the upper support plate of the grid support also generates a certain translation in the horizontal direction, making the translation and deflection of the upper support plate related. At this time, when the grid is further subjected to stress that causes the upper support plate of the support to translate, it will affect the freedom of translation of the upper support plate, thereby affecting the release of the stress that causes the upper support plate to translate on the upper support plate of the support, having certain limitations. Summary of the Invention

[0004] The present invention provides a building structure connection node to solve the above problems.

[0005] A building structure connection node of the present invention adopts the following technical solution: A building structure connection node includes an upper support plate, a lower support plate, a connection mechanism, and a limiting mechanism.

[0006] The upper support plate is horizontally arranged; the upper support plate is an elastic plate; the upper end surface of the upper support plate is connected to the grid.

[0007] The lower support plate is horizontally arranged below the upper support plate; the lower support plate is an elastic plate; the lower end surface of the lower support plate is fixed on the building foundation.

[0008] There are two connecting mechanisms, which are symmetrically arranged on the left and right between the upper support plate and the lower support plate; the connecting mechanism includes an upper vertical plate, a lower vertical plate, and a connecting bolt; the upper end of the upper vertical plate is fixed on the upper support plate, and a round hole is provided on the upper vertical plate; the lower end of the lower vertical plate is fixed on the lower support plate; a straight slot hole is provided on the lower vertical plate, and the length direction of the straight slot hole extends along the front-back direction; the axis of the connecting bolt is arranged left and right; the connecting bolt passes through the round hole and the straight slot hole; the connecting bolt is rotationally matched with the round hole and is slidably matched with the straight slot hole in the front-back direction.

[0009] The limiting mechanism is installed on the connecting bolt through the installation component.

[0010] The limiting mechanism includes a translation cam assembly and a deflection cam assembly; when the horizontal stress drives the upper support plate to drive the connecting bolt to translate a preset distance relative to the lower support plate in the straight slot hole, the translation cam assembly exerts a blocking force on the lower support plate to prevent the upper support plate from continuing to translate relative to the lower support plate; when the deflection stress drives the upper support plate to deflect relative to the lower support plate around the connecting bolt, the deflection cam assembly exerts a blocking force on the upper support plate and the lower support plate to prevent the upper support plate from continuing to deflect relative to the lower support plate; the translation cam assembly and the deflection cam assembly work independently of each other to enable the upper support plate to deflect after translation to release the deflection stress, or to translate after deflection to release the translation stress.

[0011] Furthermore, the installation component is arranged between the upper support plate and the lower support plate and is located between the two connecting bolts; the installation component includes two symmetrically arranged installation columns on the left and right; each installation column corresponds to a connecting bolt; the installation column is threadedly connected to the corresponding connecting bolt coaxially; two sliding screws are symmetrically arranged above and below the connecting bolt on the installation column; the sliding screws are parallel to the connecting bolt; the sliding screws are slidably matched with the lower vertical plate in the front-back direction; the sliding screws are threadedly connected to the installation column.

[0012] Furthermore, the deflection cam assembly is arranged between the upper support plate and the lower support plate and is located between the two installation columns; the deflection cam assembly includes a first cast steel block.

[0013] There are two first cast steel blocks symmetrically arranged above and below the axis of the connecting bolt; the ends of the two first cast steel blocks close to each other are in a gear shape; the two first cast steel blocks are meshed; the first cast steel block is rotationally matched with the sliding screw; the end of the first cast steel block far from the axis of the connecting bolt is set as the first arc end.

[0014] The first arc end is in an arc shape; the axis of the first arc end of the upper first cast steel block is below the axis of the sliding screw, and the axis of the first arc end of the lower first cast steel block is above the axis of the sliding screw; an arc-shaped plate is provided on the first arc end.

[0015] The arc-shaped plate is coaxial with the first circular arc end and is rotationally engaged with the first circular arc end around the axis of the first circular arc end; the upper arc-shaped plate abuts against the upper support plate, and the lower arc-shaped plate abuts against the lower support plate; an auxiliary structure is provided between the arc-shaped plate and the first circular arc end; when the arc-shaped plate rotates around the axis of the first circular arc end, the auxiliary structure is used to reduce the frictional resistance between the arc-shaped plate and the first circular arc end.

[0016] Further, the auxiliary structure includes a plurality of rollers circumferentially distributed along the first circular arc end; the rollers are rotatably installed on the first circular arc end and abut against the arc-shaped plate.

[0017] Further, there are two translation cam assemblies, symmetrically arranged on the left and right sides of the first cast steel block.

[0018] Further, the translation cam assembly includes a second cast steel block; the second cast steel block is sleeved and rotatably installed on the mounting column around the axis of the mounting column; the second cast steel block is arranged vertically, with the upper end being the second circular arc end and the lower end being the third circular arc end; the second circular arc end is arc-shaped and coaxial with the connecting bolt; the second circular arc end abuts against the upper support plate; the third circular arc end is arc-shaped, and the axis of the third circular arc end is above the axis of the connecting bolt.

[0019] When the horizontal stress drives the upper support plate to drive the connecting bolt to translate a preset distance relative to the lower support plate in the straight slot hole, the upper support plate drives the mounting column and the second cast steel block to translate through the connecting bolt. The lower support plate provides frictional resistance for the third circular arc end, driving the second cast steel block to rotate around the connecting bolt. Also, because the axis of the third circular arc end is above the axis of the connecting bolt, when the second cast steel block rotates around the connecting bolt, the third circular arc end exerts a cam blocking effect on the lower support plate to apply a blocking force to the lower support plate to prevent the upper support plate from continuing to translate relative to the lower support plate; during this process, the upper support plate pushes the corresponding arc-shaped plate to slide on the first circular arc end, avoiding driving the first cast steel block to rotate, and thus affecting the freedom of the upper support plate to deflect when subjected to a deflection stress.

[0020] When the deflecting stress drives the upper support plate to deflect relative to the lower support plate around the connecting bolt, the upper support plate pushes the first steel casting block, causing the two first steel casting blocks to rotate around the sliding screw. Also, since the axis of the first arc end of the upper first steel casting block is below the axis of the sliding screw and the axis of the first arc end of the lower first steel casting block is above the axis of the sliding screw, the first arc end of the upper first steel casting block exerts a cam blocking effect on the upper support plate, and the first arc end of the lower first steel casting block exerts a cam blocking effect on the lower support plate, so as to apply a blocking force to the upper support plate and the lower support plate to prevent the upper support plate from deflecting further relative to the lower support plate; during this process, since the connecting bolt and the second arc end of the second steel casting block are coaxial, when the upper support plate deflects around the connecting bolt, the upper support plate rolls on the second arc end without relative sliding. Therefore, when the upper support plate deflects, it is avoided to drive the second steel casting block to rotate and affect the freedom of the upper support plate to translate when the upper support plate is subjected to translational stress. That is, the translational cam assembly and the deflecting cam assembly work independently of each other, realizing that the upper support plate can also deflect after translation to release the deflecting stress, or the upper support plate can also translate after deflection to release the translational stress.

[0021] Further, the roller is cylindrical, and the axis of the roller is parallel to the axis of the first arc end.

[0022] Further, limit screws are threadedly connected to the front and rear ends of the arc-shaped plate; the limit screws are arranged radially along the first arc end, and the end close to the axis of the first arc end extends to the side of the arc-shaped plate close to the first steel casting block to prevent the arc-shaped plate from slipping off.

[0023] Further, the arc-shaped plate and the first arc end are slidably matched through an arc-shaped chute to realize the rotation of the arc-shaped plate around the axis of the first arc end.

[0024] Further, through grooves extending front and rear are symmetrically opened on the lower vertical plate above and below the connecting bolt; the sliding screw is slidably matched with the through groove to realize the front and rear sliding fit between the sliding screw and the lower vertical plate.

[0025] The beneficial effects of the present invention are: when the horizontal stress drives the upper support plate to drive the connecting bolt to translate a preset distance relative to the lower support plate in the straight groove hole, the translational cam assembly applies a blocking force to the lower support plate to prevent the upper support plate from translating further relative to the lower support plate; when the deflecting stress drives the upper support plate to deflect relative to the lower support plate around the connecting bolt, the deflecting cam assembly applies a blocking force to the upper support plate and the lower support plate to prevent the upper support plate from deflecting further relative to the lower support plate; the translational cam assembly and the deflecting cam assembly work independently of each other, realizing that the upper support plate can also deflect after translation to release the deflecting stress, or the upper support plate can also translate after deflection to release the translational stress.

Detailed implementation manners

[0035] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0036] An embodiment of a connection node of a building structure according to the present invention is as Figures 1 to 7 shown, and includes an upper support plate 100, a lower support plate 200, a connection mechanism, and a limiting mechanism. The upper support plate 100 is horizontally arranged; the upper support plate 100 is an elastic plate; the upper end surface of the upper support plate 100 is connected to the grid. The lower support plate 200 is horizontally arranged below the upper support plate 100; the lower support plate 200 is an elastic plate; the lower end surface of the lower support plate 200 is fixed to the building foundation through fixing bolts.

[0037] There are two connection mechanisms, which are symmetrically arranged left and right between the upper support plate 100 and the lower support plate 200; the connection mechanism includes an upper vertical plate 310, a lower vertical plate 320, and a connection bolt 330; the upper end of the upper vertical plate 310 is fixed to the upper support plate 100, and a circular hole is formed in the upper vertical plate 310; the lower end of the lower vertical plate 320 is fixed to the lower support plate 200; a straight groove hole 321 extending in the front-rear direction is formed in the lower vertical plate 320; the axis of the connection bolt 330 is arranged left and right; the connection bolt 330 passes through the circular hole and the straight groove hole 321; the connection bolt 330 is rotationally matched with the circular hole and is slidably matched with the straight groove hole 321 in the front-rear direction.

[0038] The limiting mechanism is installed on the connection bolt 330 through an installation component. The installation component is arranged between the upper support plate 100 and the lower support plate 200 and is located between the two connection bolts 330; the installation component includes two symmetrically arranged installation columns 410 left and right; each installation column 410 corresponds to a connection bolt 330; the installation column 410 is threadedly connected to the corresponding connection bolt 330 coaxially; two sliding screws 420 are symmetrically arranged up and down with respect to the connection bolt 330 on the installation column 410; the sliding screws 420 are parallel to the connection bolt 330; the sliding screws 420 are slidably matched with the lower vertical plate 320 in the front-rear direction; through grooves 322 extending in the front-rear direction are symmetrically formed up and down with respect to the connection bolt 330 on the lower vertical plate 320; the sliding screws 420 are slidably matched with the through grooves 322 to realize the sliding match between the sliding screws 420 and the lower vertical plate 320 in the front-rear direction. The sliding screws 420 are threadedly connected to the installation column 410.

[0039] The limiting mechanism includes a translation cam assembly and a deflection cam assembly. When the upper support plate 100 drives the connecting bolt 330 to translate a preset distance relative to the lower support plate 200 in the straight slot hole 321 under the drive of a horizontal stress, the translation cam assembly exerts a blocking force on the lower support plate 200 to prevent the upper support plate 100 from continuing to translate relative to the lower support plate 200. When the upper support plate 100 deflects relative to the lower support plate 200 around the connecting bolt 330 under the drive of a deflection stress, the deflection cam assembly exerts a blocking force on the upper support plate 100 and the lower support plate 200 to prevent the upper support plate 100 from continuing to deflect relative to the lower support plate 200. The translation cam assembly and the deflection cam assembly work independently of each other, enabling the upper support plate 100 to deflect after translation to release the deflection stress, or enabling the upper support plate 100 to translate after deflection to release the translation stress.

[0040] The deflection cam assembly is arranged between the upper support plate 100 and the lower support plate 200 and is located between two mounting posts 410. The deflection cam assembly includes a first cast steel block 510. Two first cast steel blocks 510 are symmetrically arranged above and below the axis of the connecting bolt 330. The ends of the two first cast steel blocks 510 close to each other are in a gear shape. The two first cast steel blocks 510 are meshed. The first cast steel block 510 is rotationally matched with the sliding screw 420. The end of the first cast steel block 510 far from the axis of the connecting bolt 330 is set as a first arc end 511. The first arc end 511 is in an arc shape. The axis of the first arc end 511 of the upper first cast steel block 510 is below the axis of the sliding screw 420, and the axis of the first arc end 511 of the lower first cast steel block 510 is above the axis of the sliding screw 420. An arc-shaped plate 520 is arranged on the first arc end 511.

[0041] The arc-shaped plate 520 and the first arc end 511 are coaxial and are rotationally matched with the first arc end 511 around the axis of the first arc end 511. The upper arc-shaped plate 520 abuts against the upper support plate 100, and the lower arc-shaped plate 520 abuts against the lower support plate 200. An auxiliary structure is arranged between the arc-shaped plate 520 and the first arc end 511. When the arc-shaped plate 520 rotates around the axis of the first arc end 511, the auxiliary structure is used to reduce the frictional resistance between the arc-shaped plate 520 and the first arc end 511. The auxiliary structure includes a plurality of rollers 530 circumferentially distributed along the first arc end 511. The rollers 530 are rotatably mounted on the first arc end 511 and abut against the arc-shaped plate 520. The rollers 530 are in a cylindrical shape, and the axis of the rollers 530 is parallel to the axis of the first arc end 511.

[0042] The front and rear ends of the arc-shaped plate 520 are threadedly connected with limit screws 540; the limit screws 540 are arranged radially along the first arc end 511, and one end close to the axis of the first arc end 511 extends to the side of the arc-shaped plate 520 close to the first steel casting block 510 to prevent the arc-shaped plate 520 from slipping off. The arc-shaped plate 520 and the first arc end 511 are slidably matched through an arc-shaped chute to realize the rotation of the arc-shaped plate 520 around the axis of the first arc end 511.

[0043] There are two translation cam assemblies, symmetrically arranged on the left and right sides of the first steel casting block 510. The translation cam assembly includes a second steel casting block 610; the second steel casting block 610 is sleeved and rotatably mounted on the mounting column 410 around the axis of the mounting column 410; the second steel casting block 610 is arranged vertically, with the upper end being the second arc end 620 and the lower end being the third arc end 630; the second arc end 620 is arc-shaped, and the second arc end 620 and the connecting bolt 330 are coaxial; the second arc end 620 abuts against the upper support plate 100; the third arc end 630 is arc-shaped, and the axis of the third arc end 630 is above the axis of the connecting bolt 330.

[0044] When the horizontal stress drives the upper support plate 100 to drive the connecting bolt 330 to translate a preset distance relative to the lower support plate 200 in the straight slot hole 321, the upper support plate 100 drives the mounting post 410 and the second cast steel block 610 to translate through the connecting bolt 330. The lower support plate 200 provides frictional resistance for the third arc end 630, driving the second cast steel block 610 to rotate around the connecting bolt 330. Also, because the axis of the third arc end 630 is above the axis of the connecting bolt 330, when the second cast steel block 610 rotates around the connecting bolt 330, the third arc end 630 exerts a cam blocking effect on the lower support plate 200 to apply a blocking force to the lower support plate 200 and prevent the upper support plate 100 from continuing to translate relative to the lower support plate 200. During this process, the upper support plate 100 pushes the corresponding arc plate 520 to slide on the first arc end 511. When the deflection stress drives the upper support plate 100 to deflect relative to the lower support plate 200 around the connecting bolt 330, the upper support plate 100 pushes the first cast steel block 510, causing the two first cast steel blocks 510 to rotate around the sliding screw 420. Also, because the axis of the first arc end 511 of the upper first cast steel block 510 is below the axis of the sliding screw 420 and the axis of the first arc end 511 of the lower first cast steel block 510 is above the axis of the sliding screw 420, the first arc end 511 of the upper first cast steel block 510 exerts a cam blocking effect on the upper support plate 100, and the first arc end 511 of the lower first cast steel block 510 exerts a cam blocking effect on the lower support plate 200 to apply blocking forces to the upper support plate 100 and the lower support plate 200 and prevent the upper support plate 100 from continuing to deflect relative to the lower support plate 200. During this process, since the connecting bolt 330 and the second arc end 620 of the second cast steel block 610 are coaxial, when the upper support plate 100 deflects around the connecting bolt 330, the upper support plate 100 rolls on the second arc end 620 without relative sliding.

[0045] Combined with the above embodiments, the working principle and process of the present invention are as follows: When the horizontal stress drives the upper support plate 100 to drive the connecting bolt 330 to translate a preset distance relative to the lower support plate 200 in the straight slot hole 321, the upper support plate 100 drives the mounting post 410 and the second cast steel block 610 to translate through the connecting bolt 330. The lower support plate 200 provides frictional resistance for the third arc end 630, driving the second cast steel block 610 to rotate around the connecting bolt 330. Also, because the axis of the third arc end 630 is above the axis of the connecting bolt 330, when the second cast steel block 610 rotates around the connecting bolt 330, the third arc end 630 exerts a cam blocking effect on the lower support plate 200 to apply a blocking force to the lower support plate 200 and prevent the upper support plate 100 from continuing to translate relative to the lower support plate 200. During this process, the upper support plate 100 pushes the corresponding arc plate 520 to slide on the first arc end 511, avoiding driving the first cast steel block 510 to rotate and thus affecting the freedom degree of the upper support plate 100 to deflect when the upper support plate 100 is subjected to deflection stress.

[0046] When the deflection stress drives the upper support plate 100 to deflect relative to the lower support plate 200 around the connecting bolt 330, the upper support plate 100 pushes the first cast steel blocks 510, causing the two first cast steel blocks 510 to rotate around the sliding screws 420. Also, since the axis of the first arc end 511 of the upper first cast steel block 510 is below the axis of the sliding screw 420, and the axis of the first arc end 511 of the lower first cast steel block 510 is above the axis of the sliding screw 420, the first arc end 511 of the upper first cast steel block 510 exerts a cam blocking effect on the upper support plate 100, and the first arc end 511 of the lower first cast steel block 510 exerts a cam blocking effect on the lower support plate 200, so as to apply a blocking force to the upper support plate 100 and the lower support plate 200 to prevent the upper support plate 100 from continuing to deflect relative to the lower support plate 200; during this process, since the connecting bolt 330 and the second arc end 620 of the second cast steel block 610 are coaxial, when the upper support plate 100 deflects around the connecting bolt 330, the upper support plate 100 rolls on the second arc end 620 without relative sliding. Therefore, when the upper support plate 100 deflects, it is avoided to drive the second cast steel block 610 to rotate and affect the freedom degree of the upper support plate 100 to translate when the upper support plate 100 is subjected to translational stress. That is, the translational cam assembly and the deflection cam assembly work independently of each other, realizing that the upper support plate 100 can also deflect after translation to release the deflection stress, or the upper support plate 100 can also translate after deflection to release the translational stress.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
