Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a steel formwork reinforcement construction structure for a masonry T-shaped structural column. Background Art

[0002] A structural column refers to a reinforced concrete structural column that should be set in the wall of a multi-story brick-concrete structure building to enhance the integrity and stability of the building, and is connected to the ring beams of each floor to form a spatial frame capable of resisting bending and shear. It is an effective measure to prevent the collapse of the house. The setting positions of the structural columns are at the four corners of the exterior wall, the intersection of the transverse wall and the exterior longitudinal wall at the staggered floor position, both sides of a larger opening, the intersection of the interior and exterior walls of a large room, etc.

[0003] The prior art, such as the utility model patent with the patent number CN 212562474 U, discloses a construction formwork for a T-shaped wall reinforced concrete structural column, which uses a support member to cross the first pair of tie rods and the second pair of tie rods to reinforce the formwork.

[0004] In the above prior art, in order to facilitate the recovery of the tie rods, a sleeve is sleeved on the part of the tie rod located in the pouring area. However, there is a longitudinal pressure in the pouring area after pouring, especially in the center of the pouring area; and there is a lack of longitudinal support in the middle of the two tie rods, especially at the cross position in the center of the pouring area, which makes the tie rods prone to bending deformation under the action of the longitudinal pressure of the concrete, increasing the loss of the tie rods, and the bending deformation will also make it difficult to take out the tie rods when removing the formwork.

[0005] In addition, in order to avoid shearing and smoothing the sleeve after removing the formwork, one end of the sleeve needs to be inclined and fitted with the flat formwork, and the other end needs to be fitted with the corner of the L-shaped formwork. The fitting surfaces are all of special shapes and are easily affected by deformation and disturbance during pouring, resulting in openings at the fitting surfaces, causing the concrete to enter the inside of the sleeve from the openings, thus bonding with the tie rods, which will further increase the loss of the tie rods and further cause the problem of difficult removal of the tie rods.

[0006] Based on this, it is necessary to study a steel formwork reinforcement construction structure for a masonry T-shaped structural column. Summary of the Utility Model

[0007] In view of this, the purpose of the utility model is to provide a steel formwork reinforcement construction structure for a masonry T-shaped structural column, which can effectively solve the problems that the tie rods in the existing reinforcement structure are prone to bending deformation under longitudinal pressure, are easily bonded with the concrete, and finally result in large loss of the tie rods and difficult removal.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A steel formwork reinforcement construction structure for a masonry T-shaped structural column, comprising a masonry, a flat formwork, an L-shaped formwork, and a tie kit;

[0010] There are two sets of the L-shaped formwork, and both the flat formwork and the L-shaped formwork are attached to the masonry and enclose a T-shaped pouring space;

[0011] There are two sets of the tie kit arranged at intervals up and down and crosswise, respectively connecting the two sets of L-shaped formwork and the flat formwork in a tie manner;

[0012] The tie kit includes triangular pads, reinforcement bushings, sleeves, and tie bolts;

[0013] Triangular pads are fixedly arranged corresponding to the corners of the outer end faces of the L-shaped formwork and the outer end faces of the flat formwork; through holes for tying are correspondingly formed on the triangular pads, the L-shaped formwork, and the flat formwork, communicating with the outside and the pouring space;

[0016] The other end of the sleeve is fixedly sleeved on the reinforcement bushing located on the flat formwork, and an inclined cut adapted to and fitting the inner surface of the flat formwork is formed on this end face;

[0017] The tie bolts pass through the through holes for tying, the reinforcement bushings, and the sleeves, and connect the L-shaped formwork and the flat formwork in a tie manner.

[0018] Further, a pressure ring is threadedly connected to the end of the reinforcement bushing located outside, and tie nuts are threadedly connected to both ends of the tie bolts;

[0019] One end of the pressure ring is in contact with the triangular pad, and the other end is in contact with the tie nut.

[0020] Further, there is a clearance between the outer end face of the end of the reinforcement bushing located outside and the tie nut.

[0021] Further, the reinforcement bushings are slidably sleeved in the through holes for tying and are fixedly connected to the triangular pads through the tying action of the tie bolts.

[0022] Further, a connecting bracket is arranged between the two sets of tie kits arranged at intervals up and down;

[0023] The connecting bracket includes an upper U-shaped clamp, a lower U-shaped clamp, and a support column, and the upper U-shaped clamp and the lower U-shaped clamp are fixedly connected through the support column;

[0024] The upper U-shaped clamp has an upward opening and is arranged in a surrounding manner around the center of the sleeve of the tensioning assembly located above;

[0025] The lower U-shaped clamp has a downward opening and is arranged in a surrounding manner around the center of the sleeve of the tensioning assembly located below.

[0026] Furthermore, multiple sets of the two cross-arranged tensioning assemblies and the connecting brackets are arranged at intervals in the vertical direction.

[0027] The beneficial effects of the above technical solution are as follows:

[0029] In addition, when the sleeve is deformed and disturbed during pouring, resulting in an opening on the fitting surface, the concrete will be blocked by the reinforcement bushing and will not directly enter the inside of the sleeve, avoiding the influence of the concrete erosion on the tensioning screw passing through the inside of the sleeve and the reinforcement bushing, and improving the service life of the tensioning screw.

Detailed implementation manners

[0037] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners:

[0038] Example 1. This example aims to provide a steel formwork reinforcement construction structure for a masonry T-shaped structural column, which is mainly used for formwork support work during the pouring of a masonry T-shaped structural column, aiming to solve the problems that in the existing reinforcement structure, the screw is prone to bending deformation under longitudinal pressure and is easily adhered to the concrete, resulting in large screw loss and difficulty in removal.

[0039] A steel formwork reinforcement construction structure for a masonry T-shaped structural column, as shown in Figure 1 and Figure 2 , includes a masonry structure 1, a flat formwork 2, two L-shaped formworks 3, and a tensioning kit 5; there is a set of flat formworks 2, and two sets of L-shaped formworks 3 are provided. The flat formwork 2 and the L-shaped formworks 3 are both attached to the masonry structure 1 and enclose a T-shaped pouring space 4.

[0040] There are two sets of tensioning kits 5 arranged at intervals up and down and crosswise, respectively connecting the two L-shaped formworks 3 and the flat formwork 2 in a tensioning manner; the tensioning kit 5 includes a triangular spacer 501, a reinforcing bushing 502, a sleeve 503, and a tensioning screw 504. Triangular spacers 501 are fixedly provided at the corners of the outer end faces of the L-shaped formworks 3 and the outer end faces of the flat formwork 2. The triangular spacers 501 are isosceles right triangles. The tensioning screw 504 passes through the triangular spacer 501 at the corner of the L-shaped formwork 3 and passes out from the flat formwork 2. Triangular spacers 501 are correspondingly provided at the passing-out positions of the flat formwork 2. The triangular spacers 501 mainly provide a stable tensioning and fixing foundation for the fasteners at both ends of the tensioning screw 504, thereby improving the stability of the tensioning structure.

[0041] As shown in Figure 3 , through holes communicating with the outside and the pouring space 4 are correspondingly provided on the triangular spacers 501, the L-shaped formworks 3, and the flat formwork 2; the reinforcing bushing 502 is fixedly sleeved in the through holes and extends into the pouring space 4 to provide a fixing foundation for both ends of the sleeve 503. The sleeves 503 are distributed in the pouring space 4, as shown in Figure 3-5, one end of the sleeve 503 is fixedly sleeved on the outer surface of the reinforcement bushing 502 located on the L-shaped template 3. The end face is provided with a V-shaped notch adapted to the corner of the inner surface of the L-shaped template 3, and is kept in contact with the corner of the inner surface of the L-shaped template 3 through the V-shaped notch; the other end of the sleeve 503 is fixedly sleeved on the outer surface of the reinforcement bushing 502 located on the flat template 2. The end face is provided with an inclined plane notch adapted to the inner surface of the flat template 2, and is kept in contact with the flat template through the inclined plane notch; the tension tie rod 504 passes through the tension tie hole, the reinforcement bushing 502 and the sleeve 503, and tension tie connects the L-shaped template 3 and the flat template 2. The reinforcement bushing 502 can effectively support the sleeve 503, can reduce the longitudinal compressive force formed by the concrete on the tension tie rod 504 inside the sleeve 503 during pouring, greatly relieve the deformation problem of the tension tie rod 504, and can also make the sleeve 503 fit with the inner surface of the template, avoiding the problem that the sleeve 503 needs to be cut subsequently after passing through the template, reducing the workload and improving the construction efficiency.

[0042] To facilitate the fixation of the reinforcement bushing 502, as Figure 3 and Figure 6 , the reinforcement bushing 502 is slidably sleeved in the tension tie hole. A pressure ring 505 is threadedly connected to the end of the reinforcement bushing 502 located outside. Tension tie nuts 506 are threadedly connected to both ends of the tension tie rod 504. The tension tie nuts 506 are mainly used as fasteners for the tension tie rod 504; one end of the pressure ring 505 is in contact with the triangular cushion block 501, and the other end is in contact with the tension tie nut 506. When the tension tie nuts 506 at both ends of the tension tie rod 504 form a tension tie, the pressure ring 505 will be tightly attached to the outer surface of the triangular cushion block 501 to form a fixation, so that the reinforcement bushing 502 is fixedly connected to the triangular cushion block 501 through the tension tie action of the tension tie rod 504.

[0043] To prevent the tension tie nut 506 from contacting the reinforcement bushing 502 and affecting the contact and tightness effect between the tension tie nut 506 and the pressure ring 505, there is an avoidance gap between the outer end face of the end of the reinforcement bushing 502 located outside and the tension tie nut 506.

[0044] To improve the integrity of the two sets of tension tie kits 5 arranged crosswise, as Figure 5, a connecting bracket 6 is arranged between two sets of tensioning kits 5 arranged at intervals up and down; the connecting bracket 6 includes an upper U-shaped clamp 601, a lower U-shaped clamp 602 and a support column 603, and the upper U-shaped clamp 601 and the lower U-shaped clamp 602 are fixedly connected through the support column 603; the upper U-shaped clamp 601 has an upward opening and is arranged around the center of the sleeve 503 of the tensioning kit 5 located above; the lower U-shaped clamp 602 has a downward opening and is arranged around the center of the sleeve 503 of the tensioning kit 5 located below. The connecting bracket 6 longitudinally connects two sets of tensioning kits 5 arranged crosswise up and down, so that the longitudinal force received by the upper tensioning kit 5 can be shared to the lower tensioning kit 5, jointly resisting the longitudinal force and improving the ability of the tensioning kit 5 to resist the longitudinal acting force.

[0045] As Figure 1 , multiple sets of two sets of tensioning kits 5 arranged crosswise and the connecting bracket 6 are arranged at intervals in the vertical direction, continuously reinforcing the formwork, and the connecting bracket 6 is only arranged between two sets of tensioning kits 5 arranged crosswise in the same group.

[0046] The usage method of this embodiment is as follows: First, arrange the flat formwork 2, pass through the reinforcing bushing 502 from the triangular cushion block 501 on the flat formwork 2, and then sleeved one end of the sleeve 503 on the reinforcing bushing 502; after continuously arranging the reinforcing bushing 502 and the sleeve 503 on one side of the flat formwork 2, arrange the L-shaped formwork 3, pass through the reinforcing bushing 502 from the triangular cushion block 501 on the L-shaped formwork 3, and sleeved the other end of the sleeve 503; finally, pass through the tensioning screw 504 and perform tensioning and fixing.
