Description

Technical Field

[0001] The utility model relates to the technical field of building reinforcement, in particular to a jacket frame for reinforcing and reconstructing a building structure. Background Art

[0002] At present, with the development of cities, some older buildings have cracks in the walls and weakening of the strength of the reinforcing steel bars, posing safety hazards to the buildings. Due to economic considerations, many dilapidated buildings will not be demolished and rebuilt. In many cases, the concrete structure is artificially reinforced, generally using a frame structure to enhance the stability of the concrete structure.

[0003] In the prior art, the reinforcement of the supporting columns of a house often needs to be carried out through a sheath-type frame. When the traditional sheath-type frame is put on the supporting column, it is necessary to cover multiple positive corners of the supporting column with angle steels, leave gaps, and then connect multiple angle steels through welding connecting strips, thereby completing the cage structure for reinforcing and transforming the supporting column.

[0004] However, the cage-type outer frame applied to the supporting columns of the house needs to be welded. In actual application, the angle steel covering the supporting columns is relatively large. When welding with the connecting strips on site, the welding stress cannot be effectively released, resulting in the angle steel being prone to deformation, thereby reducing the cage-type reinforcement effect on the supporting columns. In view of this, we propose a outer frame for strengthening and transforming building structures. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide an outer sleeve frame for strengthening and transforming building structures to solve the problem that the current outer sleeve frame is easily deformed due to the inability to effectively release the welding stress when being welded to the connecting strip on site, thereby reducing the technical problem of the cage-type reinforcement effect on the supporting column.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a jacket frame for strengthening and renovating a building structure, including a cage-type reinforcement component sleeved on a support column for improving the overall strength of the support column and two end seats respectively installed at the top and bottom ends of the cage-type reinforcement component;

[0007] The cage-type reinforcement assembly includes a plurality of support angle irons distributed at the positive angles of the support columns, a plurality of groups of movable grooves are evenly spaced on both sides of the plurality of support angle irons, and a scissor-type tensioning assembly is movably installed in two groups of movable grooves at the same height between two adjacent support angle irons, and the scissor-type tensioning assembly includes an X-shaped support plate and a plurality of fixing assemblies hingedly installed at the four ends of the X-shaped support plate;

[0008] The fixing assembly includes a sliding seat, which is detachably mounted on one side of the sliding seat facing the supporting angle iron, and the sliding seat is slidably mounted in the movable groove, a guide plate is centrally constructed on the outer edge surface of the sliding seat, and a guide groove for the guide plate to slide is centrally opened in the movable groove.

[0009] Preferably, the scissor-type tensioning assembly comprises a shaft rod, and connecting plates are rotatably mounted on both ends of the outer edge surface of the shaft rod, and both ends of the connecting plate are respectively hingedly connected to the corresponding sliding seats.

[0010] Preferably, the two shafts and the two adjacent supporting angle irons form two diagonally arranged deformable triangular energy-absorbing cavities, and the size of the triangular energy-absorbing cavities changes with the distance between the two supporting angle irons.

[0011] Preferably, a limit plate is constructed at one end of the sliding seat away from the connecting plate, and limit grooves for slidingly setting the limit plate are provided on both sides of the supporting angle iron.

[0012] Preferably, two through slots are symmetrically provided on one side of the sliding seat away from the supporting angle iron, and fastening bolts are movably arranged in the two through slots, and one end of the fastening bolt extending out of the through slot is threadedly connected in the sliding seat.

[0013] Preferably, four corners of the top end of the end seat are provided with insertion grooves, and the supporting angle irons are inserted into the insertion grooves.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model realizes cage-type reinforcement for the support column by the cooperation of a cage-type reinforcement component and two end seats. When a vertical force is received, four support angle irons cooperate with the support column for support, and the force is dispersed to the ground through the two end seats. The support of the two end seats around the top and bottom of the support column reduces the force acting on the support column. When a horizontal load is received on the support column, the support column is cooperated with multiple support angle irons and multiple scissor-type tensioning components for connecting the support angle irons. The triangular energy absorption cavity formed by the two shafts and the two adjacent support angle irons greatly improves the structural strength of the reinforced support column. The adjustable connection method is convenient for on-site assembly without welding, thereby avoiding the problem that welding stress cannot be effectively released.

[0016] 2. The utility model cooperates with multiple supporting angle irons and multiple scissor-type tensioning components. By distributing multiple supporting angle irons at the positive angles on the supporting column and adjusting the angle between the two connecting plates on the shaft rod, two adjacent supporting angle irons can be connected through multiple scissor-type tensioning components. After the connection is completed, the two connecting plates cooperate with the two adjacent supporting angle irons to form a triangular energy absorption cavity that can change with the change of the distance between the two adjacent supporting angle irons. The multiple supporting angle irons inserted in the two end seats are cooperated to realize the overall reinforcement of the supporting column structure. When bearing load, fine-tuning can be performed according to the size of the load, and there is no need to open holes on the supporting column for fixing, which reduces the damage to the supporting column structure and further improves the reinforcement effect of the support column.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1: A jacket frame for strengthening and renovating a building structure, see Figure 1 , including a cage-type reinforcement component 2 sleeved on the support column 1 for improving the overall strength of the support column 1 and two end seats 3 respectively installed at the top and bottom ends of the cage-type reinforcement component 2;

[0025] Further, in order to change the assembly method to avoid the problem that welding stress cannot be effectively released, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The cage-type reinforcement component 2 includes a plurality of support angle irons 201 distributed at the positive corners of the support column 1, and the four corners of the top of the end seat 3 are provided with insertion slots, and the support angle irons 201 are inserted into the insertion slots, and multiple groups of movable slots 202 are evenly spaced on both sides of the plurality of support angle irons 201, and a scissor-type tensioning component 4 is movably installed in two groups of movable slots 202 located at the same height between two adjacent support angle irons 201, and the scissor-type tensioning component 4 includes an X-shaped support plate and a plurality of fixing components 5 hingedly installed at the four ends of the X-shaped support plate. The cage-type reinforcement of the support column 1 is realized by the cooperation of the cage-type reinforcement component 2 and the two end seats 3. When a vertical force is received, the four support components 202 are used to tighten the support column 1. The support angle iron 201 cooperates with the support column 1 for support, and disperses the force to the ground through the two end seats 3. The support of the two end seats 3 around the top and bottom of the support column 1 reduces the force acting on the support column 1. When receiving the horizontal load acting on the support column 1, the support column 1 cooperates with multiple support angle irons 201 and multiple scissor-type tensioning components 4 for connecting the support angle irons 201. The triangular energy absorption cavity formed by the two shafts 401 and the two adjacent support angle irons 201 greatly improves the structural strength of the reinforced support column 1, and adopts an adjustable connection method, which is convenient for on-site assembly without welding, thereby avoiding the problem of ineffective release of welding stress.

[0026] Furthermore, in order to achieve the overall reinforcement of the support column 1 structure and further improve the reinforcement effect of the support column 1, see Figure 3 , Figure 4 , Figure 5The scissor-type tensioning assembly 4 includes a shaft 401, and both ends of the outer edge surface of the shaft 401 are rotatably mounted with connecting plates 402, and the two ends of the connecting plate 402 are respectively hingedly connected to the corresponding sliding seat 501, and the two shafts 401 and the two adjacent support angle irons 201 form two diagonally arranged deformable triangular energy absorption cavities, and the size of the triangular energy absorption cavity changes with the distance between the two support angle irons 201. Through the cooperation of multiple support angle irons 201 and multiple scissor-type tensioning assemblies 4, by distributing multiple support angle irons 201 at the positive angles on the support column 1, and by adjusting the shaft 40 1, so that two adjacent support angle irons 201 can be connected through multiple scissor-type tensioning components 4. After the connection is completed, the two connecting plates 402 cooperate with the two adjacent support angle irons 201 to form a triangular energy absorption cavity that can change with the change of the spacing between the two adjacent support angle irons 201, and cooperate with the multiple support angle irons 201 inserted in the two end seats 3 to achieve the overall reinforcement of the support column 1 structure. When bearing loads, fine adjustments can be made according to the size of the load, and there is no need to open holes on the support column 1 for fixing, which reduces the damage to the support column 1 structure and further improves the reinforcement effect of the support column 1.

[0027] It is worth noting that in order to further improve the energy absorption effect of the horizontal load and to improve the reinforcement effect of the support column 1, see Figure 4 , Figure 5 The fixing assembly 5 includes a sliding seat 501, a sliding seat 502 is detachably mounted on one side of the sliding seat 501 facing the supporting angle iron 201, and the sliding seat 502 is slidably mounted in the movable groove 202, a guide plate 503 is centrally constructed on the outer edge surface of the sliding seat 502, and a guide groove 203 for the guide plate 503 to slide is centrally opened in the movable groove 202, a limiting plate 504 is constructed at one end of the sliding seat 501 away from the connecting plate 402, and limiting grooves 204 for the limiting plate 504 to slide are opened on both sides of the supporting angle iron 201, and two through grooves are symmetrically opened on one side of the sliding seat 501 away from the supporting angle iron 201, and the two through grooves are symmetrically opened. Each of the through grooves is movably provided with a fastening bolt 505, and one end of the fastening bolt 505 extending out of the through groove is threadedly connected to the sliding seat 502. By tightening multiple fastening bolts 505, the sliding seat 501 is abutted against one side of the supporting angle iron 201, thereby increasing the friction during contact. When affected by horizontal loads, the sliding seat 501 hingedly installed on one end of the connecting plate 402 will rotate around the shaft 401 as the axis when the shared load is greater than the friction between the sliding seat 501 and the supporting angle iron 201, thereby completing the deformation of the triangular energy absorption cavity, further improving the energy absorption effect for horizontal loads, and greatly improving the reinforcement effect of the support column 1.
