Detailed Implementation

[0029] like Figure 1-4 In this paper, a modular prefabricated roof eaves formwork support device for brick-concrete structure includes multiple support frames 3 that are detachably and parallelly arranged on the outside of the brick-concrete wall 1. The upper side of the support frame 3 is connected to a steel pipe 5 by multiple baffles 4. The upper side of the steel pipe 5 supports multiple wooden blocks 6. The wooden blocks 6 form the pouring space of the eaves 9 through the bottom mold 7, the side mold 8 and the wooden strips 10.

[0030] Traditional construction methods use steel pipe supports, which involve many components, are difficult to install and dismantle, and pose certain safety risks during construction. This solution uses a brick-concrete wall 1 as a fixed foundation, supports the support frame 3 as the bottom support for the steel pipe 5, and uses baffles 4 to limit the steel pipe 5 to prevent it from slipping. This facilitates the pouring and sealing of the eaves 9 using timber 6, bottom formwork 7, side formwork 8, and wooden strips 10, ensuring convenient construction of the eaves 9 while achieving better quality.

[0031] like Figure 5-9 In the preferred embodiment, the support frame 3 includes a first angle steel 301, a second angle steel 302, and a third angle steel 303 connected end to end. The first angle steel 301, the second angle steel 302, and the third angle steel 303 are connected to form a triangular structure. The first angle steel 301 is connected to the brick-concrete wall 1 through multiple locking parts 2.

[0032] The support frame 3 adopts a triangular structure, which uses less material, is structurally stable, uses readily available angle steel, and is easy to manufacture. The locking part 2 can stably and firmly connect the support frame 3 and the brick-concrete wall 1.

[0033] In the preferred embodiment, multiple mounting holes 101 and a third through hole 306 are respectively provided on the brick-concrete wall 1 and the first angle steel 301. The locking member 2 includes a locking rod 201 and a locking nut 202. The locking rod 201 passes through the mounting holes 101 and the third through hole 306, and the locking nut 202 and the locking rod 201 are threaded together.

[0034] The quick installation of the locking rod 201 and the locking nut 202 ensures that the first angle steel 301 is fully attached to the side of the brick-concrete wall 1, thereby improving the overall stability and ensuring balanced force. After use, the locking rod 201 and the support frame 3 can be disassembled by releasing the locking nut 202, which is simple to operate.

[0035] In a preferred embodiment, the locking rod 201 includes a large-diameter portion 203 and a small-diameter portion 204. The inner diameter of the mounting hole 101 matches the outer diameter of the large-diameter portion 203, and a plurality of grooves 205 are provided circumferentially on the outer side of the large-diameter portion 203.

[0036] By setting the groove 205, the large-diameter part 203 can be stably inserted into the mounting hole 101. The mounting hole 101 is drilled later to facilitate timely adjustment of the installation height and position of the support frame 3 according to the position of the eaves 9, ensuring construction safety and efficiency. The later drilling operation is more convenient. In addition, after construction, the mounting hole 101 is sealed with concrete to ensure the structural airtightness and aesthetics of the brick-concrete wall 1. Since the mounting hole 101 is constructed on the brick-concrete wall 1, it is impossible to guarantee that the inside of the mounting hole 101 is absolutely smooth. Therefore, the large-diameter part 203 can be stably embedded in the mounting hole 101 through the groove 205, ensuring sufficient and stable force.

[0037] In a preferred embodiment, the end of the lock nut 202 is provided with a lock sleeve 206, the outer diameter of the lock sleeve 206 matches the inner diameter of the mounting hole 101, and the lock nut 202 and the lock sleeve 206 are respectively threaded to the small diameter portion 204.

[0038] The length of the large-diameter portion 203 is shorter than the length of the mounting hole 101. The lock nut 202, through the lock sleeve 206, ensures a secure fixation to the small-diameter portion 204, while also being able to adapt to variations in the thickness of the brick-concrete wall 1 within a certain range, making it more convenient to use. The outer diameter of the lock sleeve 206 is slightly smaller than the inner diameter of the mounting hole 101, thus ensuring that after the lock sleeve 206 extends into the mounting hole 101, it supports the small-diameter portion 204.

[0039] In the preferred embodiment, the first angle steel 301 is provided with a first through hole 304 and a second through hole 305, the second angle steel 302 is provided with a fourth through hole 307 and a first oblong hole 308, and the third angle steel 303 is provided with a fifth through hole 309 and a second oblong hole 310. The first angle steel 301, the second angle steel 302 and the third angle steel 303 are respectively connected to the nut 12 by screws 11.

[0040] By setting the first oblong hole 308 and the second oblong hole 310, the installation is flexible and can be adjusted within a certain range, avoiding the problem of not being able to fix it due to errors in hole position manufacturing, and thus improving its versatility.

[0041] In the preferred embodiment, the upper side of the second angle steel 302 is fixed to the baffle 4 by screws 11 and nuts 12. The second angle steel 302 is also provided with a limiting member 13, which includes a round rod 1301 and a pressure rod 1302. The pressure rod 1302 is pressed onto the top of the steel pipe 5. A locking hole 601 is provided through the wooden block 6. The locking hole 601 is connected to the steel pipe 5 by a steel wire.

[0042] During construction, the timber 6 can be stably pressed onto the steel pipe 5 under its own weight. In order to further ensure the stability of the timber 6, the steel wire is tied and fixed to the steel pipe 5 through the locking hole 601. The limiting part 13 can ensure that the steel pipe 5 will not move along the axial direction after it is placed on the baffle 4, thus ensuring the safety and stability of the construction.

[0043] In the preferred embodiment, the second angle steel 302 is provided with a sixth through hole 311 and a first threaded hole 312, the baffle 4 is provided with a through hole 401, the screw 11 is inserted into the through hole 401 and the sixth through hole 311, and the round rod 1301 is threadedly connected to the first threaded hole 312.

[0044] The angle and height of the pressure rod 1302 can be adjusted by rotating the round rod 1301, thereby changing the connection state between it and the steel pipe 5, which facilitates the installation and removal of the steel pipe 5 and makes the operation convenient.

[0045] like Figure 10-11 In the preferred embodiment, the upper side of the round rod 1301 is provided with a sliding groove 1304 and a thread 1305, the end of the pressure rod 1302 is provided with a ring 1306, the inner side of the ring 1306 is provided with a protrusion 1307, the protrusion 1307 is located in the sliding groove 1304, and the pressure rod 1302 is connected by a stop sleeve 1303 and a thread 1305.

[0046] With the cooperation of the sliding groove 1305 and the protrusion 1307, the round rod 1301 and the pressure rod 1302 are kept in a relatively locked state, and no circumferential rotation occurs, that is, the angle does not change. At the same time, with the cooperation of the stop sleeve 1303, the ring 1306 on the pressure rod 1302 is prevented from axial movement, resulting in high locking accuracy and good effect.

[0047] In the preferred embodiment, the stop sleeve 1303 and the round rod 1301 are threaded together, and the bottom of the round rod 1301 is provided with a screwing post 1308.

[0048] It is easy to operate and has a good locking effect. The position of the round rod 1301 can be quickly adjusted by rotating the screw rod 1308, thereby changing the angle and height of the pressure rod 1302.

[0049] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
