Description

Technical Field

[0001] The utility model relates to the technical field of steel structure installation support, in particular to a steel structure beam support seat. Background Art

[0002] Steel structure beam support seats are used in rigid frames, frame beam systems and other similar steel beam structures. Generally, steel structure beam support seats need to provide stable support for the beam end structure, mainly playing the role of transmitting force and stabilizing the structure. Their design and construction usually need to be determined according to specific engineering requirements and force characteristics.

[0003] For example, a support seat for a steel box girder is disclosed in a patent document with patent publication number CN214737297U, whose main structure includes a bridge support column and a steel box girder, a support seat is fixedly provided on the upper end of the bridge support column, the steel box girder is installed on the upper end of the support seat, the support seat is installed at the connecting position of two sections of the steel box girder, dampers are fixedly installed on both sides of the support seat, and a clamping groove and an arc-shaped groove are opened on the upper end surface of the support seat.

[0004] It can be seen from the above-mentioned prior art that when it is working, it mainly finds the installation position when connecting and installing the bridge, and realizes three-level buffering and shock absorption through support buffer block one, support buffer block two and support buffer block three. However, this support seat has the following problems when it is actually applied to the installation and construction of box-type steel structure beams: First, the existing patent literature only relies on the bottom support when supporting the box-type steel structure beam, and lacks the necessary lateral protection; second, the four-point hinged method has no load-bearing effect on the support of the entire box-type steel structure beam. When the entire box-type steel structure beam relies on the lateral reinforcement fixing frame in the middle to complete the support, it is not suitable for large load conditions and the supporting effect is poor; third, the multi-point hinged seat parts need to be drilled when connected to the bottom of the box-type steel structure beam, which makes the construction steps cumbersome.

[0005] To this end, the utility model optimizes and improves the steel structure beam support problems existing in the prior art, and hereby proposes a new type of steel structure beam support seat which can be easily constructed and installed and ensure the bottom support effect of the box-type steel structure beam, so as to better solve the problems existing in the prior art.

DETAILED DESCRIPTION

[0025] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 6 as shown in .

[0026] Embodiment 1: A steel structure beam support seat comprises a steel-concrete column 1, a bottom connecting portion 2 is fixedly connected to the bottom of the steel-concrete column 1, a support platform 3 is integrally formed on the top of the steel-concrete column 1, main shock-absorbing units are respectively arranged on the left and right sides of the top of the support platform 3, a central compression shock-absorbing unit is arranged between the two main shock-absorbing units, the support platform 3 cooperates with the central compression shock-absorbing unit and the two main shock-absorbing units to support the bottom of the steel structure box beam 4 installed thereon, and compression side support mechanisms are respectively arranged on the upper parts of the front and rear sides of the steel-concrete column 1; in the installed state, the two compression side support mechanisms cooperate to achieve lateral limitation of the left and right sides of the steel structure box beam 4.

[0027] The overall structure of the steel structure beam support seat in this design is simple, and the construction operation is more convenient and quick. During construction, it is necessary to first position the bottom of the steel structure beam support seat by relying on the bottom connection part, and then cooperate with the external lifting equipment to gradually lower the corresponding end of the steel structure box beam 4 horizontally. When the bottom of the steel structure box beam 4 abuts against the top of the central pressure-absorbing shock-absorbing unit raised above the middle, the self-weight of the steel structure box beam 4 will gradually press down the central pressure-absorbing shock-absorbing unit, and each central shock-absorbing spring 8 inside the central pressure-absorbing shock-absorbing unit will be compressed and gradually deformed, and finally the top of the central pressure-absorbing shock-absorbing unit will be aligned with the top of the main shock-absorbing units on both sides. In addition, in the process of passive downward pressure of the downward pressure center pressure damping unit, the bottoms on both sides of the downward pressure center pressure damping unit will continuously push downward the corresponding pressure side support mechanisms on both sides, so that the pressure side support mechanisms passively change from an idle state to a working state. At this time, the pressure side support mechanisms will limit the two sides of the steel structure box girder 4, further ensuring the stability of the installation of the steel structure box girder 4; when installed in place, the construction personnel will install the expansion bolts 6 at the positions of each main damping unit, thereby completing the final fixation of the steel structure box girder 4.

[0028] In any of the above schemes, it is preferred that the main shock-absorbing unit includes a shock-absorbing rubber pad 5 fixedly mounted on the top of one side of the support platform 3, the top of the shock-absorbing rubber pad 5 abuts against the bottom of the steel structure box girder 4, and expansion bolts 6 are screwed into the screw holes on the front and rear sides of the bottom of the support platform 3, and the upper ends of the expansion bolts 6 extend to the inside of the steel structure box girder 4 for fixation.

[0029] The main shock-absorbing unit adopts a shock-absorbing rubber pad 5 as a shock-absorbing structure, which can achieve the purpose of shock absorption through deformation when bearing the gravity of the steel structure box girder 4; in addition, the locking and positioning of each expansion bolt 6 can ensure the connection reliability between the entire steel structure box girder 4 and the supporting platform 3.

[0030] In any of the above schemes, it is preferred that the central pressure-bearing shock-absorbing unit includes a vertically arranged inverted U-shaped clamping seat 7, and the inverted U-shaped clamping seat 7 is integrally fixedly formed by a horizontal pressure-bearing part 701 arranged above the space between the two shock-absorbing rubber pads 5 and a vertical clamping part 702 arranged on the front and rear sides of the steel-concrete column 1; a plurality of central shock-absorbing springs 8 are arranged at intervals on the top of the support platform 3 directly below the horizontal pressure-bearing part 701, and the top of each of the central shock-absorbing springs 8 is fixed to the bottom of the horizontal pressure-bearing part 701, and the bottom of each of the central shock-absorbing springs 8 is fixed to the top of the support platform 3.

[0031] It should be noted that there are two functions of adding a central pressure-absorbing shock-absorbing unit. One is that it is used as a secondary buffering and shock-absorbing component in conjunction with the shock-absorbing rubber pads 5 on both sides, relying on the shock absorption and buffering of multiple central shock-absorbing springs 8 to improve the overall buffering and shock-absorbing effect; the second is that when subjected to the gravity of the steel structure box girder 4, the downward movement of the inverted U-shaped clamping seat 7 can trigger the compression side support mechanism on its front and rear sides to shift to the limit position state, thereby completing the lateral limit support for the steel structure box girder 4.

[0032] In any of the above schemes, it is preferred that the bottom of each of the vertical clamping parts 702 located on the front and rear sides is set to a vertically downward inverted triangle structure 703, and the inclined sides on both sides of the inverted triangle structure 703 are used to downwardly abut the pressure side support mechanism at the corresponding position; when the installation is completed, the top of the inverted U-shaped clamping seat 7 is flush with the top of the two shock-absorbing rubber pads 5.

[0033] When the entire inverted U-shaped clamping seat 7 moves downward, it will drive the vertical clamping parts 702 on both sides to move downward continuously. During the downward movement, the inverted triangle structure 703 can continuously push the two lateral limit members 9 of the compressed side support mechanism downward to achieve flipping. After the lateral limit members 9 are flipped into place, they will abut against the side walls of the steel structure box girder 4, and finally complete the limit.

[0034] Preferably, in any of the above solutions, the thickness of the shock-absorbing rubber pad 5 is 5 cm-10 cm.

[0035] The shock-absorbing rubber pad 5 of appropriate thickness can ensure the supporting effect and the connection stability effect when performing shock-absorbing support.

[0036] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features:

[0037] In any of the above schemes, it is preferred that the compressed side support mechanism includes two horizontal positioning shafts 10 respectively fixed on the corresponding side walls of the steel-concrete column 1, and the two horizontal positioning shafts 10 are symmetrically arranged on both sides of the inverted triangle structure 703 of the vertical clamping part 702 at the corresponding positions, and a lateral limit member 9 is movably sleeved on the outer wall of each horizontal positioning shaft 10, and the lateral limit member 9 includes a vertically arranged swing arm 901, and the mounting hole at the top of the swing arm 901 is movably sleeved on the outer wall of the horizontal positioning shaft 10, and a horizontally arranged compressed rotating part 902 is integrally formed on the inner side of the top of the swing arm 901, and the inner end of the compressed rotating part 902 is arranged toward the inclined side of the inverted triangle structure 703, and a limited clamping part 903 is integrally formed on the outer side of the bottom of the swing arm 901; in a working state, the limited clamping part 903 is used to abut against the side wall of the steel structure box girder 4 at the corresponding position.

[0038] The compressed side support mechanism in this embodiment mainly adopts the method of arranging fixed-axis rotatable lateral limit members 9 on both sides, and at the same time relies on the downward pressure of the inverted triangle structure 703 of the vertical clamping part 702 on the top to provide driving force for the rotation of the corresponding lateral limit member 9, so that the lateral limit member 9 can be rotated into place. After it is in place, the inverted triangle structure 703 of the vertical clamping part 702 is pressed and locked to ensure that the lateral limit member 9 will not return to its position automatically, thereby completing the limiting and tightening of the side wall of the steel structure box girder 4.

[0039] The lateral limit member 9 is sleeved on the outer wall of the horizontal positioning shaft 10 to achieve fixed-axis rotation when subjected to force; here, the horizontally arranged pressed rotating part 902 is in contact with the inverted triangle structure 703. When the inverted triangle structure 703 is passively moved downward, it will continuously push the pressed rotating part 902 downward, so that the swing arm 901 and the limiting clamping part 903 of the entire lateral limit member 9 complete the rotation, and finally the upper end of the limiting clamping part 903 abuts against the corresponding side wall of the steel structure box girder 4, and relies on the deadweight of the steel structure box girder 4 to achieve locking positioning to improve the limiting effect.

[0040] In any of the above solutions, preferably, a rounded surface 704 is provided at the bottom of the inverted triangle structure 703 .

[0041] The provided rounded curved surface 704 can ensure smoothness of pressing when the pressed rotating parts 902 on both sides are pressed downward.

[0042] Specific working principle: During construction, it is necessary to first position the bottom of the steel structure beam support seat by relying on the bottom connection part, and then cooperate with external lifting equipment to gradually lower the corresponding ends of the steel structure box beam 4 horizontally.

[0043] When the bottom of the steel structure box girder 4 abuts against the top of the central pressure-absorbing shock-absorbing unit raised above the middle part, the central pressure-absorbing shock-absorbing unit will be gradually pressed down by its own weight, and each central shock-absorbing spring 8 inside the central pressure-absorbing shock-absorbing unit will be compressed and gradually deformed, eventually making the top of the central pressure-absorbing shock-absorbing unit flush with the tops of the main shock-absorbing units on both sides.

[0044] In addition, during the passive downward pressure of the downward pressure center pressure damping unit, the bottoms on both sides of the downward pressure center pressure damping unit will continuously push downward the corresponding pressure side support mechanisms on both sides, so that the pressure side support mechanisms passively change from an idle state to a working state. At this time, the pressure side support mechanisms will limit the two sides of the steel structure box girder 4, further ensuring the stability of the installation of the steel structure box girder 4.

[0045] After the installation is in place, the construction personnel install the expansion bolts 6 at the positions of the main shock absorbing units, thereby completing the final fixation of the steel structure box girder 4.

[0046] In summary, it can be seen that the steel structure beam support seat in the present design is relatively simple in the installation and construction steps of the steel structure box girder 4. The steel structure box girder 4 is directly hoisted and moved downward, and the lateral limitation of the steel structure box girder 4 is automatically completed after it is moved into place. Finally, the installation can be completed by installing each expansion bolt 6 for positioning; the main shock-absorbing units on both sides are relied on to realize and buffer shock absorption, and the shock absorption stability after installation is ensured; the central pressure shock-absorbing unit is used to cooperate with the main shock-absorbing units on both sides to realize secondary shock absorption, which effectively improves the shock absorption effect and ensures the firmness of the connection; in addition, when the bottom of the steel structure box girder 4 is supported, the self-weight of the steel structure box girder 4 during construction can be relied on to trigger the downward movement of the central pressure shock-absorbing unit, thereby realizing the control of the compressive side support mechanisms on both sides to flip to both sides, and finally achieving the lateral abutment limitation of the steel structure box girder 4 using the lateral limiter 9, and further strengthening the installation stability of the steel structure box girder 4.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
