Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically a device for preventing concrete from sliding down a sloping roof. Background Technology

[0002] Sloping roofs mainly include single-slope, double-slope, four-slope, and zigzag types, which have advantages such as beautiful shape, clear outline, and smooth drainage. In modern cities, most sloping roof structures are based on reinforced concrete cast-in-place slab structures. Unlike flat roofs, sloping roof concrete is prone to flow and slippage during the pouring process. This means the concrete can only form naturally on the sloping roof without restraint, making it difficult to control the density of the concrete and achieve the desired forming quality, leaving potential leakage hazards. Utility Model Content

[0003] To address the problem that existing technologies struggle to control the density of concrete on sloping roofs, resulting in suboptimal molding quality and potential leakage, this invention provides a device to prevent concrete from sliding down sloping roofs. This device consists of a fixed rod that is permanently connected to reinforcing bars on the sloping roof. An installation plate is fixedly connected to one end of the fixed rod facing the bottom of the sloping roof, and a blocking strip is fixedly connected to the installation plate. When concrete slides down the sloping roof, it is blocked by the blocking strip.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a device for preventing concrete from sliding down a sloping roof includes a fixing rod fixedly connected to the steel bars on the sloping roof. One end of the fixing rod faces the top of the sloping roof and the other end faces the bottom of the sloping roof. An installation plate is fixedly connected to the end of the fixing rod facing the bottom of the sloping roof. A blocking strip is fixedly connected to the installation plate. There is an angle between the blocking strip and the installation plate. When the concrete slides down the sloping roof, it can be blocked by the blocking strip.

[0005] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to this utility model: the mounting plate is provided with multiple strip-shaped mounting holes, and a strip-shaped fixing block is fixedly connected to one end of the fixing rod facing the bottom of the sloping roof. The fixing rod and the fixing block are parallel to each other. When the fixing block is parallel to the mounting hole, the fixing block can pass through the mounting hole. When the fixing block passes through the mounting hole and has an angle with the mounting hole, the fixing rod and the fixing block can clamp the mounting plate.

[0006] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to this utility model: the fixing rod and the fixing block are connected by a connecting rod, the connecting rod can pass through the mounting hole, a fixing ring is sleeved on the connecting rod, the fixing ring is located between the fixing rod and the fixing block, and after the fixing block passes through the mounting hole, both the fixing ring and the fixing block are in contact with the mounting plate.

[0007] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to this utility model: the end of the fixing rod facing the bottom of the sloping roof is bent to be perpendicular to the fixing rod to form the connecting rod.

[0008] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to this utility model: the two ends of the mounting hole are provided with arc-shaped inner walls, which can fit against the connecting rod.

[0009] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to this utility model: the distance between the bottom of the fixing ring and the top of the fixing block is 1.05-1.2 times the thickness of the blocking strip.

[0010] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to the present invention: the blocking strip has multiple notches on the side away from the mounting plate, and the notches are spaced apart along the length of the blocking strip.

[0011] As a further optimization of the device for preventing concrete from sliding down a sloping roof according to the present invention: the mounting hole is provided with an anti-slip groove on the side wall near the top of the sloping roof.

[0012] As a further optimization of the device for preventing the concrete of a sloping roof from sliding down, the fixing rod is fixedly connected to the reinforcing steel bars on the sloping roof concrete by tie wire.

[0013] As a further optimization of the device for preventing concrete from sliding down a sloping roof, the blocking strip, mounting plate and fixing rod are all made of carbon steel.

[0014] Beneficial effect: The end of the fixing rod facing the bottom of the sloping roof is fixedly connected to the mounting plate, and the mounting plate is fixedly connected to the blocking strip. There is an angle between the blocking strip and the mounting plate, so that the concrete can be blocked by the blocking strip when it slides down the sloping roof.

[0015] The fixing rod is connected to the fixing block by a connecting rod that can pass through the mounting hole. A fixing ring is fitted on the connecting rod, which can better restrict the movement of the fixing rod and improve the stability of the device.

[0016] The side of the barrier strip away from the mounting plate has multiple notches, which are spaced apart along the length of the barrier strip. The notches reduce the overall weight of the barrier strip, save materials, and ensure that the concrete can better wrap the barrier strip and the mounting plate, thus improving the overall integrity.

[0017] Anti-slip grooves are provided on the side wall near the top of the sloping roof to prevent relative sliding between the fixing rod and the mounting plate, thereby improving the stability of the fixing rod. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the structure and material of the tie wire 4, the type and structure of the steel bar 5, and how the concrete is poured on the sloping roof, etc.

[0026] Example 1

[0027] A device to prevent concrete from sliding down a sloping roof, such as Figures 1-3 As shown, the structure includes a fixing rod 3 fixedly connected to the reinforcing steel bars 5 on the sloping roof. One end of the fixing rod 3 faces the top of the sloping roof, and the other end faces the bottom of the sloping roof. An installation plate 2 is fixedly connected to the end of the fixing rod 3 facing the bottom of the sloping roof. A blocking strip 1 is fixedly connected to the installation plate 2, with an angle between the blocking strip 1 and the installation plate 2, preferably 90°. This angle allows the blocking strip 1 to stop the concrete from sliding down the sloping roof. The fixing rod 3 is fixedly connected to the reinforcing steel bars 5 on the sloping roof concrete using tie wires 4. There are two connection methods, such as... Figure 5 As shown, if during installation the length direction of the reinforcing bar 5 is perpendicular to the length direction of the blocking strip 1, the fixing rod 3 should be placed at the bottom of the mounting plate 2, that is, the fixing rod 3 should be located between the mounting plate 2 and the reinforcing bar 5; Figure 6 As shown, if the length direction of the reinforcing bar 5 is parallel to the length direction of the blocking strip 1 during installation, the fixing rod 3 is placed on top of the mounting plate 2, that is, the fixing rod 3 is located above the mounting plate 2 and the reinforcing bar 5. Multiple sets of this device can be installed in parallel on the sloping roof to improve the effect of preventing the concrete of the sloping roof from sliding down.

[0028] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0029] Example 2

[0030] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figures 1-3 As shown, the mounting plate 2 has multiple strip-shaped mounting holes 201. The mounting plate 2 is also strip-shaped. The axes of all mounting holes 201 are on the same straight line, and all mounting holes 201 are evenly distributed along the length of the mounting plate 2. The end of the fixing rod 3 facing the bottom of the sloping roof is fixedly connected to a strip-shaped fixing block 302. The fixing rod 3 and the fixing block 302 are parallel to each other. When the fixing block 302 is parallel to the mounting hole 201, the fixing block 302 can pass through the mounting hole 201. Because the fixing rod 3 and the mounting hole 201 are parallel to each other, the fixing block 302 can pass through the mounting hole 201. The fixing block 302 is parallel, therefore, the fixing rod 3 is also parallel to the mounting hole 201. In order to ensure that the fixing block 302 does not come out of the mounting hole 201 after passing through, the fixing block 302 and the fixing rod 3 will be rotated as a whole. When the fixing block 302 has an angle with the mounting hole 201 after passing through the mounting hole 201, the fixing rod 3 and the fixing block 302 can clamp the mounting plate 2. Then, the fixing rod 3 is fixed to the mounting plate 2 using the tie wire 4. The angle between the fixing block 302 and the mounting hole 201 is 90°.

[0031] Example 3

[0032] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4 As shown, the fixing rod 3 and the fixing block 302 are connected by a connecting rod 301. The connecting rod 301 can pass through the mounting hole 201. A fixing ring 303 is fitted on the connecting rod 301. The distance between the bottom of the fixing ring 303 and the top of the fixing block 302 is 1.05-1.2 times the thickness of the blocking strip 1. The fixing ring 303 is located between the fixing rod 3 and the fixing block 302. After the fixing block 302 passes through the mounting hole 201, both the fixing ring 303 and the fixing block 302 are in contact with the mounting plate 2. The fixing ring 303 can better restrict the movement of the fixing rod 3 and improve the stability of the device. The blocking strip 1, mounting plate 2, fixing block 302, fixing ring 303 and fixing rod 3 are all made of carbon steel.

[0033] Example 4

[0034] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4 As shown, the end of the fixing rod 3 facing the bottom of the sloping roof is bent to be perpendicular to the fixing rod 3 to form the connecting rod 301, which facilitates processing.

[0035] Example 5

[0036] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 As shown, the mounting hole 201 has arc-shaped inner walls 2012 at both ends. The arc-shaped inner walls 2012 can fit with the connecting rod 301 and can better cooperate with the movement of the connecting rod 301 in the mounting hole 201.

[0038] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 As shown, the side of the blocking strip 1 away from the mounting plate 2 has multiple notches 101. The notches 101 are distributed at intervals along the length of the blocking strip 1. The setting of the notches 101 reduces the overall weight of the blocking strip 1, saves materials, and also ensures that the concrete can better wrap the blocking strip 1 and the mounting plate 2, thus improving the overall integrity.

[0039] Example 7

[0040] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 As shown, due to the inclination of the sloping roof, the mounting plate 2 tends to slide down along the bottom of the sloping roof. Therefore, an anti-slip groove 2011 is provided on the side wall of the mounting hole 201 near the top of the sloping roof to prevent relative sliding between the fixing rod 3 and the mounting plate 2, thereby improving the stability of the fixing rod 3.
