Description

Technical Field

[0001] This invention relates to a structural column reinforcement fixing structure and its construction method for building construction, belonging to the field of building engineering technology. Background Technology

[0002] Structural columns are installed to enhance the integrity and stability of a building. In multi-story brick-concrete structures, reinforced concrete structural columns should also be installed in the walls, connecting to the ring beams of each floor to form a spatial frame capable of resisting bending and shearing. This is an effective measure to prevent building collapse. Structural columns are typically placed at the four corners of exterior walls, at the intersection of transverse and longitudinal walls in staggered floor sections, on both sides of large openings, and at the intersection of interior and exterior walls in large rooms.

[0003] Before pouring the structural column, it is necessary to tie the reinforcement cage. The reinforcement cage consists of longitudinal steel bars and transverse steel rings. The traditional construction method is for the operator to attach the steel rings to the steel bars and then fix the steel bars and steel rings together with tie wire. The process of fixing the steel bars and steel rings together with tie wire is time-consuming and will prolong the construction period. Moreover, when fixing with tie wire, one hand needs to hold the tie wire and the other hand needs to hold the tool, which makes it impossible for the operator to climb the ladder, making the construction process more dangerous. At the same time, since only the bottom of the steel bar is fixed in this process, the single steel bar is prone to tilting and deformation, which not only increases the difficulty of tying for the operator, but also causes the reinforcement cage to deform. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings of the prior art by providing a structural column reinforcement fixing structure and its construction method for building construction. Its structure is compact, equipped with multiple fixing mechanisms to increase stability, and features a T-shaped support rod, support cylinder, and spring in the middle to prevent tilting and deformation of any steel column during the fixing process. It also has a buffering and shock-absorbing function, facilitating construction and reducing labor costs.

[0005] The technical solution of the present invention: a structural column reinforcement fixing structure for building construction, comprising structural column reinforcement, the structural column reinforcement comprising: reinforcement 1, reinforcement 2, reinforcement 3 and reinforcement 4, wherein the structural column reinforcement is fixed by fixing mechanism 1 and fixing mechanism 2;

[0006] The fixing mechanism one includes: a fixing strip four sleeved on the outside of steel bar one, steel bar two, steel bar three and steel bar four, the fixing strip four having an open end, the open end being fixed by a insertion mechanism, steel bar one and steel bar three being fixed by a fixing mechanism three fixed on the fixing strip four; steel bar two and steel bar four are surrounded by an arc-shaped rod one, one end of the arc-shaped rod one being movably connected to an arc-shaped rod two, and the other end being fixed on the fixing strip four;

[0007] The second fixing mechanism includes: a fixing strip 1 for mounting steel bars 1 and 3, a fixing strip 2 for mounting steel bars 2 and 4, the fixing strip 1 and the fixing strip 2 being arranged crosswise, and the fixing strip 3 being mounted at the intersection of the fixing strip 1 and the fixing strip 2.

[0008] In the aforementioned structural column reinforcement fixing structure for building construction, the fixing strip four is provided with a socket that matches the end of the arc-shaped rod, and the end of the arc-shaped rod is inserted into the socket.

[0009] In the aforementioned structural column reinforcement fixing structure for building construction, each of the two arc-shaped rods is connected to a T-shaped support rod on its back. The other ends of the two T-shaped support rods extend into the inside of the support cylinder, and a spring is fixedly connected to the inner end of the T-shaped support rod located in the support cylinder.

[0010] In the aforementioned structural column reinforcement fixing structure for building construction, the fixing mechanism one is set above the fixing mechanism two, and the two are evenly distributed on the structural column reinforcement.

[0011] In the aforementioned structural column reinforcement fixing structure for building construction, the open end includes an insertion end and a containing end. The port of the containing end adjacent to the insertion end is provided with an insertion hole, and the insertion end can be inserted into the insertion hole.

[0012] In the aforementioned structural column reinforcement fixing structure for building construction, the insertion mechanism includes: a through-tube fixed at the insertion hole position of the containing end, a T-shaped insertion rod passing through the through-tube, the T-shaped insertion rod extending into the insertion hole after passing through the through-tube, a baffle fixedly sleeved on the rod body of the T-shaped insertion rod located in the through-tube, a spring sleeved on the rod body between the baffle and the surface of the containing end, one end of the spring abutting against the bottom surface of the outer cover of the through-tube, and the other end fixedly connected to the baffle, and a slot adapted to the T-shaped insertion rod is provided on the rod body of the insertion end.

[0013] In the aforementioned structural column reinforcement fixing structure for building construction, the fixing mechanism three includes: rod one and rod two rotatably connected to fixing bar four, with the other end of rod one passing through the opening slot at the other end of rod two.

[0014] In the aforementioned structural column reinforcement fixing structure for building construction, the adjacent ends of rod one and rod two are both hinged with side pins.

[0015] In the aforementioned structural column reinforcement fixing structure for building construction, when the arc-shaped rod two is closed, it contacts the fixing strip four.

[0016] A construction method for fixing reinforcing steel bars in structural columns for building construction includes the following steps:

[0017] S1: A set of fixing strips includes one and three reinforcing bars;

[0018] S2: Fixed strip two is fitted with steel bar two and steel bar four;

[0024] S8: Insert the arc-shaped rod 1 of the fixing mechanism 1 onto the fixing bar 4, and surround the steel bar 2 and steel bar 4 respectively through the two arc-shaped rods 1 and 2.

[0025] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention, by setting up fixing mechanisms one, two and three, connects the four steel bars constituting the steel cage with the fixing mechanisms to form a whole, and each steel bar is individually surrounded by fixing mechanisms one and three. When a steel bar has a tendency to tilt or deform, under the synergistic effect of the fixing mechanisms, the other steel bars will resist or pull the steel bar that is about to tilt or deform, thus preventing it from tilting or deforming.

[0026] This invention has a compact structure and multiple fixing mechanisms, which increases stability. The middle part of the fixing mechanism one is equipped with a T-shaped support rod, a support cylinder, and a spring two, which prevents the steel bar column from tilting and deforming during the fixing process. It also has a buffer and shock absorption function, making construction convenient and reducing the labor force of workers. Attached Figure Description

Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0034] An embodiment of the present invention: a structural column reinforcement fixing structure for building construction, such as... Figure 1-5 As shown, it includes structural column reinforcement 1, which includes: reinforcement 1.1, reinforcement 2.2, reinforcement 3.3 and reinforcement 4.4. The structural column reinforcement 1 is fixed by fixing mechanism 1.2 and fixing mechanism 2.

[0035] The fixing mechanism 12 includes: a fixing strip 4 sleeved on the outside of steel bars 1.1, 1.2, 1.3, and 1.4; the fixing strip 4 has an open end 5; steel bars 1.1, 1.2, 1.3, and 1.4 are inserted into the fixing strip 4 through the open end 5; the open end 5 is fixed by a insertion mechanism 6; steel bars 1.1 and 1.3 are fixed by a fixing mechanism 7 fixed on the fixing strip 4; the two fixing mechanisms 7 surround and fix steel bars 1.1 and 1.3. Steel bars 1.2 and 1.4 are surrounded by an arc-shaped rod 18; one end of the arc-shaped rod 18 is movably connected to an arc-shaped rod 29, and the other end is fixed to the fixing strip 4. Reinforcing bars 1.2 and 1.4 are surrounded by arc-shaped rods 8 and 9, thus enclosing reinforcing bars 1.1, 1.2, 1.3, and 1.4 at the four corners of the fixing bar 4.

[0036] The fixing mechanism 2 3 includes: a fixing strip 3.1 for mounting steel bars 1.1 and 3.3, and a fixing strip 3.3 for mounting steel bars 2.2 and 4.4. The fixing strip 3.1 and the fixing strip 3.3 are arranged to cross each other, and the fixing strip 3.2 is used at the intersection of the fixing strip 3.1 and the fixing strip 3.3. Multiple fixing strips 3.1 and 3.3 are inserted into the ends of the structural column reinforcement 1 and moved to the required position. Then, fixing strip 3.2 is used to tie and fix it. Fixing strip 3.2 has a structure similar to binding wire. During the tightening process of fixing strip 3.2, fixing strips 3.1 and 3.3 are squeezed, so that the ends of fixing strips 3.1 and 3.3 tightly hug the structural column reinforcement 1 under the inward squeezing force. Under the action of friction, fixing strips 3.1 and 3.3 are tightly connected to the structural column reinforcement 1. When the structural column reinforcement 1 is installed vertically, fixing strips 3.1 and 3.3 will not slide downward.

[0037] The fixing strip 4 is provided with a socket that matches the end of the arc-shaped rod 8. The end of the arc-shaped rod 8 is inserted into the socket. After the structural column steel bars 1 are inserted into the fixing strip 4 from the open end 5 and distributed in the four corners, the arc-shaped rod 8 is then inserted into the fixing strip 4. The steel bars 1.2 and 1.4 are inserted into the enclosing ring formed by the arc-shaped rod 8, the arc-shaped rod 9, and the fixing strip 4.

[0038] Each of the two arc-shaped rods 8 has a T-shaped support rod 10 connected to its back. The other ends of the two T-shaped support rods 10 extend into the inside of the support cylinder 11, and a spring 12 is fixedly connected to the inner end of the T-shaped support rod 10 in the support cylinder 11. That is, each end of the spring 12 is fixedly connected to one end of one T-shaped support rod 10. When one of the reinforcing bars 1.2 and 1.4 tilts or deforms and presses the arc-shaped rod 8 inward, the pressing force is transmitted to the T-shaped support rod 10, and then to the spring 12. The spring 12 buffers the pressing force and reduces the vibration caused by the reinforcing bars 1.2 or 1.4 pressing the arc-shaped rod 8.

[0039] The fixing mechanism 2 is positioned above the fixing mechanism 3, and both are evenly distributed on the structural column reinforcement 1. Since the fixing mechanism 3 can be well fixedly connected to the structural column reinforcement 1 under frictional force, when the structural column reinforcement 1 is in a vertical state and the fixing mechanism 2 slides downwards under its own weight, the fixing mechanism 3 can support the fixing mechanism 2. By setting multiple fixing mechanisms 2 at different positions on the structural column reinforcement 1 and placing them on the fixing mechanism 3, the tilting or deformation of a particular structural column reinforcement 1 can be better controlled.

[0040] The open end 5 includes an insertion end 5.1 and a containing end 5.2. The containing end 5.2 has an insertion hole near the port of the insertion end 5.1, into which the insertion end 5.1 can be inserted. The fixing strip 4 is a steel bar. By pulling its left and right sides outward by hand, the open end 5 can be opened, facilitating the insertion of the structural column steel bar 1. After the structural column steel bar 1 is inserted, the left and right sides of the fixing strip 4 are pressed against each other, so that the insertion end 5.1 is inserted into the containing end 5.2. Then, the opening end 5 is fixed by the insertion and fixing mechanism 6 to prevent the insertion end 5.1 from sliding outward from the containing end 5.2 due to the rebound force.

[0041] The insertion mechanism 6 includes: a through-tube 6.3 fixed at the insertion hole position of the including end 5.2; a T-shaped insertion rod 6.2 passing through the through-tube 6.3 and extending into the insertion hole; a baffle 6.5 fixedly sleeved on the rod of the T-shaped insertion rod 6.2 located in the through-tube 6.3; a spring 6.4 sleeved on the rod between the baffle 6.5 and the surface of the including end 5.2; one end of the spring 6.4 abutting against the bottom surface of the outer cover 6.6 of the through-tube 6.3, and the other end fixedly connected to the baffle 6.5; under normal conditions, the baffle 6.5 is compressed downward by the spring 6.4, causing the end of the T-shaped insertion rod 6.2 to extend into the insertion hole. The rod of the insertion end 5.1 is provided with a slot 6.1 adapted to the T-shaped insertion rod 6.2. In order to fix the insertion end 5.1 by the insertion mechanism 6, before the insertion end 5.1 is inserted into the insertion hole of the containing end 5.2, the T-shaped insertion rod 6.2 is pulled outward so that the end of the T-shaped insertion rod 6.2 is withdrawn from the insertion hole of the containing end 5.2. At this time, the spring 6.4 is squeezed by the baffle 6.5. Then the insertion end 5.1 is inserted into the insertion hole of the containing end 5.2. Then the T-shaped insertion rod 6.2 is released. When the end of the T-shaped insertion rod 6.2 corresponds to the position of the slot 6.1 on the insertion end 5.1, the T-shaped insertion rod 6.2 is pushed outward under the elastic force of the spring 6.4 so that the T-shaped insertion rod 6.2 is inserted into the slot 6.1, thereby preventing the insertion end 5.1 from sliding outward.

[0042] The fixing mechanism 3 7 includes: rod 7.1 and rod 7.2 rotatably connected to fixing bar 4, with the other end of rod 7.1 passing through the opening slot at the other end of rod 7.2. Before reinforcing bars 1.1 and 1.3 are inserted into the fixing mechanism 3 7, rod 7.1 and / or rod 7.2 are pulled outwards, causing them to rotate outwards and their ends to form an opening, facilitating the insertion of reinforcing bars 1.1 and 1.3. After the reinforcing bars are inserted, rod 7.1 and / or rod 7.2 are pulled in the opposite direction, causing the other end of rod 7.1 to pass through the opening slot at the other end of rod 7.2, thereby surrounding and fixing reinforcing bars 1.1 and 1.3 through the two sets of rods 7.1 and 7.2.

[0043] Both the adjacent ends of rod 7.1 and rod 7.2 are hinged with side pins 7.3. By pulling the side pins 7.3, rod 7.1 or rod 7.2 can be rotated.

[0044] When the arc-shaped rod 29 is closed, it contacts the fixing strip 4, thereby forming a closed enclosure through the arc-shaped rod 29 and the arc-shaped rod 18, preventing the steel bar 21.2 or steel bar 41.4 from sliding out from the gap between the arc-shaped rod 29 and the fixing strip 4 when it tilts or deforms.

[0045] A construction method for fixing reinforcing steel bars in structural columns for building construction includes the following steps:

[0046] S1: Fixing strip 1.3.1 is fitted with reinforcing bars 1.1 and 3.3;

[0047] S2: Fixing strip 2 3.3 is fitted with reinforcing bar 2 1.2 and reinforcing bar 4 1.4;

[0048] S3: Fixing strip 3.2 is fitted at the intersection of fixing strip 1 3.1 and fixing strip 2 3.3, thereby fixing fixing mechanism 2 3 and structural column steel bar 1 together.

[0050] S5: Insert steel bars 1.1, 1.2, 1.3 and 1.4 into the fixing strip 4 from the open end 5 and place them at the four corners inside.

[0051] S6: The open end 5 of the fixing strip 4 is closed by the insertion mechanism 6;

[0052] S7: Move the fixing mechanism 37 inward to enclose the steel bar 1.1 and steel bar 1.3 respectively through the two fixing mechanisms 37;

[0053] S8: Insert the arc-shaped rod 8 of the fixing mechanism 12 into the fixing strip 4, and surround the steel bar 1.2 and steel bar 1.4 respectively through the two arc-shaped rods 18 and arc-shaped rod 29.
