Description

Technical Field

[0001] The invention belongs to the technical field of building reinforcement engineering, and in particular is a vertical support stress uniform distribution device for building reinforcement engineering. Background Art

[0002] In building reinforcement projects, in order to ensure the safety of construction, when vertical beams are used for support, their support stress is relatively concentrated. In order to improve the stress dispersion effect, it is usually necessary to use structures such as diagonal braces for assistance. However, in the vertical support work, it is necessary to focus on reinforcing the support of the beam area to reduce the support pressure between beams, because the strength at the beam is relatively higher. The current vertical support stress distribution device of the building reinforcement project is mainly supported by the ball seat and the vertical support rod. However, this support method will reduce the usable space of the area below the beam, which is inconvenient to arrange auxiliary structures such as diagonal braces on the vertical beam later. Moreover, when the stress is too large, its own compressive load cannot be further dynamically increased, which leads to the limitations of the vertical support stress distribution device of the building reinforcement project.

[0003] Therefore, a vertical support stress uniform distribution device for building reinforcement engineering is proposed to solve the above problems. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a vertical support stress uniform distribution device for building reinforcement engineering.

Hanger mechanisms are provided at the front and rear of the longitudinal beam, and lifting ropes are provided at the front and rear of the two support frames, and both ends of the lifting ropes are connected to lifting rings, and the lifting rings can be buckled on the hanger mechanism.

[0006] Preferably, the hanger mechanism includes a fixing frame, which is mounted on the longitudinal beam. A cross bar is connected to the fixing frame, and the other end of the cross bar is connected to a stress support ball.

[0007] Preferably, an oblique rod 1 located below the cross rod is connected between the fixing frame and the stress support ball.

[0008] Preferably, a group of threaded rods are sleeved inside the stress support ball, and the bottom ends of the group of threaded rods are connected to fixing rings that can be buckled with the lifting rings.

[0009] Preferably, the upper threaded sleeve on the outside of the threaded rod is provided with a hexagonal nut capable of abutting against the stress support ball.

[0010] Preferably, it also includes an adaptive tightening mechanism, which is arranged on the longitudinal beam. The adaptive tightening mechanism is provided with two mounting frames, which are respectively installed on the inner sides of the two longitudinal beams. Two diagonal rods 2 are provided in the mounting frames, and the mounting frames are connected to the arch frame 2 located below the cross beam.

[0011] Preferably, sleeve rods are fixedly installed on both sides of the interior of the second arch frame, a lifting sleeve is provided with a round rod inside the sleeve rod, the top of the round rod is connected to a ball head located above the sleeve rod, and ball seats are connected on both sides of the bottom of the beam, and the ball head abuts against the ball seat.

[0012] Preferably, the outer fixing sleeve of the round rod is provided with a fixing sleeve located inside the sleeve rod, the bottom of the fixing sleeve is connected to a spring located outside the round rod, and the other end of the spring is connected to the inner wall of the sleeve rod.

[0013] Preferably, the bottom end of the round rod passes through the sleeve rod and is connected to a push rod, movable grooves are provided on both sides of the push rod, a sleeve frame is fixedly sleeved below the outside of the sleeve rod, pressure arms are movably installed below both sides of the sleeve frame, and an extrusion rod that can move in the movable groove is provided in the pressure arm.

[0014] Preferably, the outer end of the pressure arm is connected to a connecting ring sleeved on the outside of the lifting rope.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an arch frame and a stress concentration ball. Construction workers pass the threaded rod through the stress support ball, which can drive the fixing ring upward. Due to the interaction force of the two fixing rings, the lifting rope can be tightened. Then the construction workers screw the threaded rod through the hexagonal nut. At this time, the tightening of the lifting rope can generate an upward force on the support frame and the arch frame. Due to the design of the arch frame, the upward force can be evenly distributed to each support rod, and the upward force can be evenly distributed to the fixing plate through the support rod through the stress concentration ball. The force of each fixing plate is uniformly distributed, and at the same time, each area of ​​the cross beam can be evenly affected by the upward force. This design can strengthen the supporting force of the reinforced cross beam, ensure that different areas of the cross beam can be evenly distributed when subjected to stress, increase the stress intensity range of the cross beam, and avoid collapse caused by excessive local force on the cross beam. Moreover, since the overall structure is arranged above the inner side of the longitudinal beam, a larger usable space can be provided below it.

[0016] The present invention provides stress support balls and fixing frames. When the cross beam is subjected to pressure, the pressure can be concentrated to the support rod through the fixing plate, the support rod and the stress concentration ball. The support rod acts on the arch frame one, and the force uniformly distributed characteristic of the arch surface of the arch frame one acts on the suspension rope through the support frame. The force is applied to the stress support ball through the suspension ring, the fixing ring, the threaded rod and the hexagonal nut. The force is applied to the longitudinal beam through the force uniformly distributed characteristic of the stress support ball and the support of the oblique rod one, the cross beam and the fixing frame, thereby ensuring that all parts of the cross beam can be further supported by the longitudinal beam when subjected to pressure, thereby improving the vertical stress bearing strength of the cross beam.

[0017] The present invention provides a connecting ring and a pressure arm. When the beam is subjected to excessive pressure and slightly bends and deforms, it will act on the ball seat, and drive the ball head, fixed sleeve and round rod to descend through the ball seat. At this time, the spring is further compressed, and the push rod will descend together. The pressure arm is driven to rotate along the axis of the sleeve through the extrusion rod, so that the connecting ring is lifted and exerts tension on the suspension rope, so that the suspension rope is further tightened, and at the same time, a greater upward force is exerted on the arch frame and the fixed plate, further improving the vertical support of the beam. This design can dynamically and adaptively compensate for the upward force of the device on the beam during the process of excessive pressure, further improving the support performance of the device on the beam, and avoiding the risk of the beam breaking and collapsing due to excessive pressure.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, the present invention provides a vertical support stress uniform distribution device for building reinforcement engineering, comprising two longitudinal beams 1 and a transverse beam 2; The crossbeam 2 is arranged on the two longitudinal beams 1, and two groups of fixed plates 3 are provided below the crossbeam 2. A group of support rods 4 arranged in a cone shape are connected to the bottom of the fixed plate 3, and a stress concentration ball 5 is connected to the bottom of one group of support rods 4. The center of the bottom of the stress concentration ball 5 is connected to a support rod 6, and an arch frame 7 is connected to the bottom of one group of support rods 6. Support frames 8 are connected to both sides of the bottom of the arch frame 7. Hanger mechanisms 10 are provided at the front and rear of the longitudinal beam 1, and lifting ropes 11 are sleeved at the front and rear of the two support frames 8. Both ends of the lifting ropes 11 are connected to lifting rings 12, and the lifting rings 12 can be buckled on the hanger mechanism 10.

[0022] The above scheme is adopted: when the lifting rope 11 is tightened by the hanger mechanism 10, an upward force can be generated on the support frame 8 and the arch frame 7 through the tightening of the lifting rope 11. Due to the design of the arch frame 7, the upward force can be evenly distributed to each strut 6, and through the uniform force distribution characteristic of the spherical body of the stress concentration ball 5, the upward force is evenly distributed to the fixed plate 3 through the support rod 4, so that each fixed plate 3 is subjected to force, and at the same time, each area of ​​the beam 2 can be evenly subjected to the upward force, thereby achieving the reinforcement of the supporting force of the reinforced beam 2, and ensuring that the stress in different areas of the beam 2 can be evenly distributed.

[0023] like Figures 1 to 4 and Figure 6As shown, the hanger mechanism 10 includes a fixing frame 101 , which is mounted on the longitudinal beam 1 , a cross bar 103 is connected to the fixing frame 101 , and a stress support ball 104 is connected to the other end of the cross bar 103 .

[0024] like Figures 1 to 4 and Figure 6 As shown, an oblique rod 102 located below the cross rod 103 is connected between the fixing frame 101 and the stress support ball 104 .

[0025] like Figures 1 to 4 and Figure 6 As shown, a group of threaded rods 105 are sleeved inside the stress support ball 104 , and the bottom ends of the group of threaded rods 105 are connected to a fixing ring 107 that can be buckled with the lifting ring 12 .

[0026] like Figures 1 to 4 and Figure 6 As shown, the upper threaded sleeve of the outer portion of the threaded rod 105 is threaded with a hexagonal nut 106 that can abut against the stress support ball 104 .

[0027] Adopting the above scheme: the construction workers pass the threaded rod 105 through the stress support ball 104, which can drive the fixing ring 107 upward. Due to the interaction force between the two fixing rings 107, the lifting rope 11 can be tightened. Then the construction workers tighten the threaded rod 105 with the hexagonal nut 106, so that the tightening of the lifting rope 11 can generate an upward force on the support frame 8 and the arch frame 7.

[0028] like Figure 3 、 Figure 5 、 Figures 7 to 10 As shown, it also includes an adaptive tightening mechanism 13, which is arranged on the longitudinal beam 1. The adaptive tightening mechanism 13 is provided with two mounting frames 131, and the two mounting frames 131 are respectively installed on the inner sides of the two longitudinal beams 1. Two inclined rods 134 are provided in the mounting frames 131, and the mounting frames 131 are connected to the arch frame 132 located below the cross beam 2.

[0029] like Figure 3 、 Figure 5 、 Figures 7 to 10 As shown, a sleeve rod 133 is fixedly installed on both sides of the interior of the arch frame 2 132, and a round rod 136 is provided in the lifting sleeve of the sleeve rod 133. The top of the round rod 136 is connected to a ball head 137 located above the sleeve rod 133, and ball seats 135 are connected on both sides of the bottom of the beam 2, and the ball head 137 abuts against the ball seat 135.

[0030] like Figure 3 、 Figure 5 、 Figures 7 to 10As shown, the outer fixing sleeve of the round rod 136 is provided with a fixing sleeve 138 located inside the sleeve rod 133 , and the bottom of the fixing sleeve 138 is connected to a spring 139 located outside the round rod 136 , and the other end of the spring 139 is connected to the inner wall of the sleeve rod 133 .

[0031] like Figure 3 、 Figure 5 、 Figures 7 to 10 As shown, the bottom end of the round rod 136 passes through the sleeve rod 133 and is connected to the push rod 1310. Movable grooves 1311 are provided on both sides of the inside of the push rod 1310. A sleeve frame 1312 is fixedly sleeved below the outside of the sleeve rod 133. Pressure arms 1313 are movably installed below both sides of the inside of the sleeve frame 1312. An extrusion rod 1314 that can move in the movable groove 1311 is provided in the pressure arm 1313.

[0032] like Figure 3 、 Figure 5 、 Figures 7 to 10 As shown, the outer end of the pressure arm 1313 is connected to a connecting ring 1315 which is sleeved on the outside of the suspension rope 11.

[0033] The above solution is adopted: when the beam 2 is slightly bent and deformed by excessive pressure, it will act on the ball seat 135, and the ball head 137, the fixing sleeve 138 and the round rod 136 will be driven down through the ball seat 135. At this time, the spring 139 is further compressed, and the push rod 1310 will drop together. The pressure arm 1313 is driven to rotate along the axis of the sleeve 1312 through the extrusion rod 1314, so that the connecting ring 1315 will be lifted and a pulling force is applied to the suspension rope 11, so that the suspension rope 11 is further tightened, and at the same time, a greater upward force is applied to the arch frame 7 and the fixing plate 3, further improving the vertical support of the beam 2, so that the upward force of the device on the beam 2 can be dynamically increased during the process of excessive pressure.

[0034] The working principle and use process of the present invention: The construction workers pass the threaded rod 105 through the stress support ball 104, which can drive the fixing ring 107 upward. Due to the interaction force between the two fixing rings 107, the lifting rope 11 can be tightened. Then the construction workers screw the threaded rod 105 through the hexagonal nut 106. At this time, the tightening of the lifting rope 11 can generate an upward force on the support frame 8 and the arch frame 7. Due to the design of the arch frame 7, the upward force can be evenly distributed to each support rod 6, and the upward force can be evenly distributed to the fixing plate 3 through the support rod 4 through the uniform force distribution characteristic of the stress concentration ball 5. At the same time, each fixing plate 3 is subjected to force, and each area of ​​the beam 2 can be evenly subjected to the upward force, thereby strengthening the supporting force of the reinforced beam 2 and ensuring that different areas of the beam 2 are evenly distributed when subjected to stress. Moreover, since the overall structure is arranged above the inner side of the longitudinal beam 1, a larger usable space can be provided below it.

[0035] When the crossbeam 2 is under pressure, the pressure can be concentrated to the strut 6 through the fixed plate 3, the support rod 4 and the stress concentration ball 5, and act on the arch frame 7 through the strut 6. Through the uniform force distribution characteristics of the arch surface of the arch frame 7, the force is applied to the suspension rope 11 through the support frame 8, and the force is applied to the stress support ball 104 through the lifting ring 12, the fixing ring 107, the threaded rod 105 and the hexagonal nut 106. Through the uniform force distribution characteristics of the stress support ball 104 and the support of the diagonal rod 102, the cross bar 103 and the fixing frame 101, the force is applied to the longitudinal beam 1, thereby ensuring that all parts of the crossbeam 2 can be further supported by the longitudinal beam 1 when under pressure, thereby improving the vertical stress bearing strength of the crossbeam 2.

[0036] The spring 139 in the elastic compression state will exert an upward force on the beam 2 through the ball seat 135 via the fixing sleeve 138, the round rod 136 and the ball head 137, so that the central area of ​​the beam 2 can be further supported by the arch frame 132.

[0037] When the beam 2 is subjected to excessive pressure and slightly bends, it will act on the ball seat 135, and the ball head 137, the fixing sleeve 138 and the round rod 136 will be driven down through the ball seat 135. At this time, the spring 139 is further compressed, and the push rod 1310 will drop together. The pressure arm 1313 is driven to rotate along the axis of the sleeve 1312 through the extrusion rod 1314, so that the connecting ring 1315 will be lifted and a pulling force is applied to the suspension rope 11, so that the suspension rope 11 is further tightened, and at the same time, a greater upward force is applied to the arch frame 7 and the fixing plate 3, further improving the vertical support of the beam 2, so that the upward force of the device on the beam 2 can be adaptively increased during the process of excessive pressure, thereby further improving the support performance of the device on the beam 2.
