Description

Technical Field

[0001] The invention relates to the technical field of joist beams and pillars, in particular to a joist beam prestressed pillar for construction engineering. Background Art

[0002] With the development of the times, the real estate industry in today's cities is developing rapidly. Naturally, more and more buildings are being built for offices, accommodation, and entertainment, and they are getting taller and taller. The houses built in the construction projects all need beams.

[0003] The beams in existing buildings are all made of cast concrete, that is, wooden boards are used to make templates, and then concrete is poured into the templates. The templates are removed after the concrete solidifies. During the waiting time for the concrete to solidify, in order to prevent the cast beams from falling and deforming under the action of gravity, prestressed support beams are needed to support the beams. Prestressing is the compressive stress pre-applied to the structure during construction to improve the service performance of the structure. The pre-applied compressive stress during the service of the structure can fully or partially offset the tensile stress caused by the load and avoid structural damage. Prestressed concrete structure is a structure that is pre-pressed before it bears the load, so that the internal force of the concrete in the tensile zone under the action of external load produces compressive stress, which is used to offset or reduce the tensile stress caused by the external load, so that the structure will not crack or crack later under normal use.

[0004] At present, a plurality of groups of equally spaced pillars are installed at the bottom of the joist to eliminate the internal stress of the joist. However, since the joist is generally long, the number of pillars used will increase accordingly, which will cause the pillars in the house to occupy a larger area. Therefore, when decorating the house, too many pillars will often hinder the construction and affect the normal progress of the construction. In the prior art, in order to solve the above problem, one pillar will be removed between the three groups of pillars to facilitate the construction. However, the reduction in the number of pillars will lead to a reduction in the supporting surface at the bottom of the joist, which will result in the internal stress of some parts of the joist being unable to be effectively eliminated, which has a certain safety impact and also has a significant impact on the service life of the joist. Summary of the invention

[0005] Based on this, the object of the present invention is to provide a prestressed support for a joist for construction engineering to solve the technical problems mentioned in the above background.

After a group of support columns are removed, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder moves upward. At this time, the driving rod, under the action of the hydraulic cylinder, drives the auxiliary support plate to move in the opposite direction away from the main support plate at the bottom end of the support beam. When the driving rod drives the auxiliary support plate to move, the driving rod drives the rotating shaft to rotate to meet the angle change generated in the driving process, and the rotating shaft drives the driving gear to rotate after the rotation, and the driving gear drives the second tooth plate to move after the rotation, so the second pressure block is driven by the second tooth plate to move away from the second pressure sensor, so the second pressure sensor drives the electromagnet power supply to start, and after the electromagnet is energized and works It will generate repulsive force on the iron crawler, so that there can be a certain gap between the iron crawler and the auxiliary support plate, and then when the auxiliary support plate moves, the iron crawler can rotate, thereby converting sliding friction into rolling friction, reducing the resistance encountered during movement, and reducing the wear on the auxiliary support plate. When the auxiliary support plate moves to the corresponding position, the driving gear can just enable the first tooth plate to drive the first pressure block to move to the position where it is squeezed and fitted with the first pressure sensor. At this time, the first pressure sensor will control the power supply of the electromagnet to cut off, which can not only achieve the effect of saving resources, but also enable the iron crawler and the auxiliary support plate to be in a fit state again, so as to better support the detachment;

[0020] When the supporting plate is moved to the position below the locking rod, the locking rod is inserted into the locking groove under the action of the locking structure (the working principle of the locking structure has been described above and will not be repeated here), so as to limit the position of the locking block, thereby realizing the horizontal limit of the auxiliary support plate, thereby realizing the first limit of the auxiliary support plate. The limiting mechanism of the support rod is that the vertical direction limiting of the horizontal plate is realized, that is, the vertical direction limiting of the auxiliary support plate is realized, which plays the role of the third limiting mechanism of the auxiliary support plate. The above structure greatly improves the supporting effect of the auxiliary support plate through the triple limiting of the auxiliary support plate, and has extremely high stability, can effectively replace the original pillar, and has significant beneficial effects.

[0043] See also Figure 3-4 An auxiliary moving assembly 5 for assisting the auxiliary supporting plate 201 in moving is installed inside the auxiliary supporting plate 201. The auxiliary moving assembly 5 can reduce the resistance of the auxiliary supporting plate 201 when the auxiliary supporting plate 201 moves, and can also reduce the resistance between the iron crawler 202 and the auxiliary supporting plate 201, thereby improving the efficiency of movement, reducing the wear caused by friction and the load of the hydraulic cylinder 3 when the auxiliary supporting plate 201 moves.

[0045] See also Figure 5 and Figure 7 A clamping assembly 6 is also installed at the top of the main support plate 102. The clamping assembly 6 can use the gravity of the joist to realize the clamping limit of the horizontal plate 402 in the horizontal direction, thereby realizing the second limit of the auxiliary support plate 201, further improving the stability of the auxiliary support plate 201;

[0046] Specifically, the locking assembly 6 includes a movable plate 601 arranged on the end surface of the main support plate 102, and a cavity 602 is opened below the movable plate 601 and located inside the main support plate 102, the movable plate 601 is slidably connected to the inner wall of the cavity 602, and a return spring is installed on the inner wall of the cavity 602, and the top of the return spring is connected to the bottom end of the movable plate 601, and the bottom end of the return spring is connected to a support block fixed on the inner wall of the cavity 602, and a locking rod 603 fixedly connected to the bottom end of the movable plate 601 is also provided inside the cavity 602, and the outer wall of the locking rod 603 fits with the inner wall of the locking groove 406.

[0047] See also Figure 5 , Figure 8 , Fig. 9 , Fig.10The bottom end of the horizontal plate 402 is provided with a limit assembly 7, which will be unfolded when the horizontal plate 402 moves, so that the support rod 702 can be rotated and opened to achieve the limit, which plays a role in the vertical limit support of the horizontal plate 402, thus achieving the third limit of the auxiliary support plate 201, and further improving the stability of the auxiliary support plate 201;

[0048] Specifically, the limiting assembly 7 includes a placement cavity 701 opened inside the transverse plate 402, and a support rod 702 is installed inside the placement cavity 701, a transmission shaft 703 that penetrates the transverse plate 402 and extends to the outside of the transverse plate 402 is fixedly connected inside the support rod 702, and a driven gear 704 is fixedly connected to the end face of the transmission shaft 703, and a driving gear plate 705 fixed to the outer wall of the main support plate 102 is arranged in the moving direction of the driven gear 704, a bottom plate is arranged on the outer wall of the fixed end of the hydraulic cylinder 3, and a snap-fit ​​seat 706 is installed on the end face of the bottom plate, a snap-fit ​​cavity 707 is opened inside the snap-fit ​​seat 706, and a limiting hole is opened on the outer wall of the snap-fit ​​cavity 707, a limiting rod 708 that penetrates the limiting hole and extends to the outside of the limiting hole is installed on the outer wall of the support rod 702, and one end of the limiting rod 708 is located inside the support rod 702 and a snap-fit ​​structure 405 is arranged.

[0049] See also Fig.11 An arc groove is provided on the outer wall of the card block 404, and a rounded corner is provided on the bottom end of the locking rod 603, and a locking structure 405 is installed on the top end of the locking rod 603 located inside the movable plate 601, so that when the card block 404 moves, the arc groove on the outer wall can squeeze the locking rod 603, so that the locking rod 603 can move upward to the inside of the movable plate 601, and then when the locking groove 406 moves to the bottom of the locking rod 603, the locking rod 603 can limit the card block 404 through the locking structure 405.

[0050] The working principle of the present invention is as follows: first, the support column 101 and the main support plate 102 are installed at the bottom end of the joist to support the joist, and the overall support of the joist is achieved by setting multiple groups of support structures;

[0051] After a group of pillars are removed due to construction needs, the hydraulic cylinder 3 is started, and the output end of the hydraulic cylinder 3 moves upward. At this time, the driving rod 204, under the action of the hydraulic cylinder 3, drives the auxiliary support plate 201 to move away from the main support plate 102 at the bottom end of the joist. When the driving rod 204 drives the auxiliary support plate 201 to move, the driving rod 204 drives the rotating shaft 502 to rotate to meet the angle change generated during the driving process, and the rotating shaft 502 rotates and drives the driving gear 503 to rotate;

[0052] After the driving gear 503 rotates, it will drive the second tooth plate 507 to move. Therefore, the second pressure block 508 will be driven away from the second pressure sensor 509 by the second tooth plate 507. Therefore, the second pressure sensor 509 will drive the electromagnet 501 to start the power supply. After the electromagnet 501 is powered on, it will generate a repulsive force on the iron track 202, so that there can be a certain gap between the iron track 202 and the auxiliary support plate 201. Then, when the auxiliary support plate 201 moves, the iron track 202 can achieve the effect of assisting the auxiliary support plate 201 to move by rotating, thereby converting the sliding friction into rolling friction, reducing the resistance during the movement, and reducing the wear on the auxiliary support plate 201;

[0053] When the auxiliary support plate 201 moves to the corresponding position, the driving gear 503 can just enable the first tooth plate 504 to drive the first pressure block 505 to move to the position where it is pressed and fitted with the first pressure sensor 506. At this time, the first pressure sensor 506 will control the electromagnet 501 to cut off the power supply, which can not only save resources, but also make the iron track 202 and the auxiliary support plate 201 fit again, so as to better support the joist.

[0054] When the auxiliary support plate 201 moves, it will drive the cross plate 402 to move in the slide groove 401 until the block 404 on the end face of the cross plate 402 moves to the position of the slot provided on the end face of the main support plate 102, and the block 404 will pop out into the slot under the action of the engaging structure 405 (during the movement of the cross plate 402, the block 404 is in a state of squeezing the return spring 4052), thereby limiting the horizontal direction of the cross plate 402, and thus limiting the horizontal direction of the auxiliary support plate 201, thus playing the first level of limiting the auxiliary support plate 201;

[0055] Furthermore, since the movable plate 601 has been moved into the main support plate 102 under the squeezing action of the joist, the movable plate 601 has driven the engaging rod 603 to move downward into the cavity 602. When the clamping block 404 moves into the cavity 602, the clamping block 404 will squeeze the engaging rod 603 upward through the arc groove until the engaging groove 406 inside the clamping block 404 moves below the engaging rod 603. Then, the engaging rod 603 will be inserted into the engaging groove 406 under the action of the engaging structure 405 (the working principle of the engaging structure 405 has been described above and will not be repeated here), thereby limiting the clamping block 404, thereby limiting the rotation direction of the cross plate 402, and thus limiting the rotation direction of the auxiliary support plate 201, which plays a second role in limiting the auxiliary support plate 201.

[0056] Furthermore, during the movement of the horizontal plate 402, the driven gear 704 on its outer side will move to contact the driving tooth plate 705. Under the action of the driving tooth plate 705, the driven gear 704 will rotate, so that the driven gear 704 will drive the support rod 702 to rotate and open from the placement cavity 701 through the transmission shaft 703. Subsequently, the support rod 702 is manually rotated so that the support rod 702 can be inserted into the engaging seat 706. At the same time, the limit rod 708 on the outer wall of the support rod 702 will be in the engaging structure 405. Under the action, it moves out from the limiting hole opened in the snap-fit ​​seat 706 (the working principle of the snap-fit ​​structure has been recorded above and will not be repeated here), thus realizing the limiting support effect of the support rod 702 and also realizing the vertical limiting of the horizontal plate 402, that is, realizing the vertical limiting of the auxiliary support plate 201, playing the third limiting role of the auxiliary support plate 201, and the triple limiting of the auxiliary support plate 201 greatly improves the supporting effect of the auxiliary support plate 201, and has extremely high stability, and can effectively replace the original pillars.
