Description

Technical Field

[0001] This utility model belongs to the field of I-beam opening closure molds, specifically an I-beam opening closure mold. Background Technology

[0002] During the construction of high-rise buildings, due to the increased height, ordinary ground-supported scaffolding cannot meet the construction needs. In this case, cantilevered scaffolding is required. The cantilevered I-beams pass through the pre-reserved openings in the walls or upturned beams [I-beam openings] to provide support points for the cantilevered scaffolding, so that the scaffolding can be stably erected on the outside of the building, providing a safe working platform for construction workers and ensuring the smooth progress of construction.

[0003] After construction is completed, the openings of the I-beams need to be sealed. Traditionally, the sealing of the openings of the I-beams is done by using old formwork for tie-down and then pouring concrete. During construction, all the external cantilever scaffolds have been removed. Workers need to use general hoisting equipment to reach the openings of the I-beams on the exterior wall to install the formwork. This process of repeatedly taking and installing the formwork at each I-beam opening is inconvenient and greatly increases the safety risks for the workers. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an I-beam opening closure mold to solve the issues raised in the above technical background.

[0005] A mold for closing an I-beam opening includes a tie rod assembly, an auxiliary rod assembly installed at the rear end of the tie rod assembly, a second baffle assembly installed between the tie rod assembly and the auxiliary rod assembly, and a disc-shaped baffle composed of several first baffle assemblies rotatably installed at the front end of the tie rod assembly.

[0006] The first baffle assembly includes a fan-shaped baffle and a fan-shaped slider. Limiting grooves are provided on both sides of the fan-shaped slider. A hinge joint is fixedly installed in the middle of the top surface of the fan-shaped slider. A hinge groove is provided at the lower end of the fan-shaped baffle. The hinge joint is hinged to the hinge groove.

[0007] Preferably, the pull rod assembly includes a first pull rod, the outer wall of which is provided with a fan-shaped groove for matching the fan-shaped slider, the front end of which is provided with an annular groove, a first annular limiting block is fixedly installed on the outer wall of the front end of the first pull rod located at the annular groove, a second annular limiting block is fixedly installed on the outer wall of the first annular limiting block, and a threaded connection hole is provided in the middle of the rear end face of the first pull rod.

[0008] Preferably, the auxiliary rod assembly includes a threaded tie rod, a limit nut is threadedly installed on the outer wall of the threaded tie rod, and a threaded rod for use with a matching threaded connection hole is fixedly installed in the middle of the front end wall of the threaded tie rod.

[0009] Preferably, the second baffle assembly includes a second baffle that is slidably disposed between the threaded tie rod and the first tie rod, and an inlet is fixedly installed at the center of the top surface of the second baffle.

[0010] Preferably, a semi-circular block is fixedly installed on the rear end face of the first pull rod, and a rotating groove matching the semi-circular block is opened on the front end wall of the threaded pull rod.

[0011] Preferably, a groove sealing block is slidably installed in the fan-shaped groove, and a third annular limiting block is fixedly installed at the front end of the groove sealing block.

[0012] Preferably, a plurality of conical blocks are evenly distributed and fixed at the rear wall edge of the first baffle assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model places the first tie rod at the opening of the I-beam, and slides the sector-shaped slider with the sector-shaped baffle hinged on it from the rear end of the sector-shaped slide groove into the annular groove. The sector-shaped slider in the annular groove is limited by the first annular limiting block. At this time, the sector-shaped baffle is affected by its own weight and automatically rotates around the axis of the first tie rod. The installation action is repeated to complete the installation of several first baffle components. Thus, workers do not need to be hoisted to the exterior wall to install the formwork, which improves the installation efficiency and reduces the safety risks of workers during construction.

[0015] 2. This utility model solves the problem of difficult installation of external wall formwork by installing several first baffle components one by one through the tie rod assembly, thereby splicing a template larger than the opening of the I-beam. It is also simple and quick to dismantle and easy to carry. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example 1:

[0028] Reference Appendix Figure 1 To be continued Figure 5 As shown, an I-beam opening closure mold includes a tie rod assembly 1, an auxiliary rod assembly 3 installed at the rear end of the tie rod assembly 1, a second baffle assembly 4 installed between the tie rod assembly 1 and the auxiliary rod assembly 3, and a disc-shaped baffle composed of several first baffle assemblies 2 rotatably installed at the front end of the tie rod assembly 1.

[0029] The first baffle assembly 2 includes a fan-shaped baffle 201 and a fan-shaped slider 202. Limiting grooves 203 are provided on both sides of the fan-shaped slider 202. A hinge joint 204 is fixedly installed in the middle of the top surface of the fan-shaped slider 202. A hinge groove 205 is provided at the lower end of the fan-shaped baffle 201. The hinge joint 204 is hinged to the hinge groove 205.

[0030] As can be seen from the above, several first baffle assemblies 2 are installed at the front end of the tie rod assembly 1, forming a disc-shaped baffle that is then sealed on the outer wall of the I-beam opening. After installing the second baffle assembly 4 at the rear end of the tie rod assembly 1, the auxiliary rod assembly 3 is installed. The auxiliary rod assembly 3 then limits the second baffle assembly 4, so that the wall of the second baffle 401 is tightly fitted with the inner wall of the I-beam opening. That is, the disc-shaped baffle and the second baffle assembly 4 are tightly fitted at the front and rear walls of the I-beam opening, thus completing the installation. At this time, concrete is poured into the I-beam opening to seal it.

[0031] Example 2:

[0032] Reference Appendix Figure 1 To be continued Figure 5 As shown, the pull rod assembly 1 includes a first pull rod 101. A fan-shaped groove 102 matching the fan-shaped slider 202 is provided on the outer wall of the first pull rod 101. An annular groove 103 is provided on the outer wall of the front end of the first pull rod 101. A first annular limiting block 104 is fixedly installed on the outer wall of the front end of the first pull rod 101 located in the annular groove 103. A second annular limiting block 105 is fixedly installed on the outer wall of the first annular limiting block 104. A threaded connection hole 108 is provided in the middle of the rear end face of the first pull rod 101.

[0033] The auxiliary rod assembly 3 includes a threaded rod 301, a limit nut 302 is threadedly installed on the outer wall of the threaded rod 301, and a threaded rod 303 for use with matching threaded connection hole 108 is fixedly installed in the middle of the front wall of the threaded rod 301.

[0034] The second baffle assembly 4 includes a second baffle 401 slidably disposed between the threaded tie rod 301 and the first tie rod 101, and an inlet 402 is fixedly installed in the middle of the top surface of the second baffle 401.

[0035] A semi-circular block 109 is also fixedly installed on the rear end face of the first pull rod 101, and a rotating groove 304 matching the semi-circular block 109 is opened on the front end wall of the threaded pull rod 301.

[0036] A sliding block 106 is slidably installed in the fan-shaped sliding groove 102, and a third annular limiting block 107 is fixedly installed at the front end of the sliding block 106.

[0037] Several conical blocks 206 are evenly distributed and fixed at the rear wall edge of the first baffle assembly 2;

[0038] As can be seen from the above: In use, firstly, place the first pull rod 101 at the opening of the I-beam, and then slide the fan-shaped slider 202, which is hinged to the fan-shaped baffle 201, into the annular groove 103 from the rear end of the fan-shaped groove 102. The fan-shaped slider 202 in the annular groove 103 is limited by the first annular limiting block 104 [that is, the outer wall of the fan-shaped slider 202 is in contact with the inner wall of the first annular limiting block 104, so it will not fall out of the annular groove 103]. At this time, the fan-shaped baffle 201 rotates around the axis of the first pull rod 101 due to its own weight. The position of the fan-shaped slider 202 in the first baffle assembly 2 does not coincide with the position of the fan-shaped groove 102.

[0039] Repeat the above installation steps to complete the installation of several first baffle components 2. Further, slide the chute sealing block 106 into the fan-shaped chute 102, so that the front wall of the third annular limiting block 107 at the front end of the chute sealing block 106 is in contact with the wall of the fan-shaped baffle 201, thereby sealing the hinge joints of several fan-shaped baffles 201 and preventing the poured concrete from seeping into the hinge joints [i.e., the gap at the hinge joint 204 and the hinge groove 205]. The inner wall of the third annular limiting block 107 is in contact with the outer wall of several fan-shaped sliders 202, which has the same limiting action as the first annular limiting block 104. The chute sealing block 106 seals the fan-shaped chute 102 to prevent concrete from entering the fan-shaped chute 102.

[0040] After the above installation is completed, the limit nut 302 is installed on the threaded tie rod 301, and then the second baffle 401 is installed on the threaded tie rod 301. The threaded tie rod 301 is rotated further so that the threaded rod 303 enters the threaded connection hole 108 and the semi-arc block 109 is located in the rotating groove 304, thereby completing the installation of the threaded tie rod 301. The semi-arc block 109 and the rotating groove 304 cooperate with each other to prevent the threaded rod 303 from bending, and at the same time improve the bending resistance of the connection between the threaded tie rod 301 and the first tie rod 101.

[0041] After the threaded tie rod 301 is installed, the limiting nut 302 on the threaded tie rod 301 is rotated to make the second baffle 401 slide on the threaded tie rod 301 and move closer to the inner wall surface of the wall until it is tightly attached to the inner wall surface. That is, the wall surface of the fan-shaped baffle 201 is tightly attached to the outer wall surface of the wall. The friction between the conical block 206 on the fan-shaped baffle 201 and the outer wall surface is generated, thereby reducing the influence of the weight of several fan-shaped baffles 201 on the threaded tie rod 301 and the first tie rod 101.

[0042] After the above installation is completed, concrete is poured into the H-beam opening through the material inlet 402 to seal it.

[0043] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
