Description

Technical Field

[0001] This utility model relates to the field of U-beam technology, and in particular to an antifreeze device for U-beam construction. Background Technology

[0002] U-shaped beams are a type of under-deck structural beam. Compared to traditional box girders, this beam type is not only more aesthetically pleasing but also offers better noise reduction, higher cross-sectional utilization, and lower cost. U-shaped beams are commonly used in bridge and road construction. However, during winter construction in northern regions, the low temperatures can cause soil, concrete, and mortar to freeze, severely impacting the concrete pouring and subsequent curing of U-shaped beams, and easily leading to quality defects.

[0003] To address the aforementioned issues, Chinese utility model CN221942008U discloses a U-shaped beam winter construction insulation device. This device includes a beam body, an insulation tarpaulin, and an insulation box. The inner bottom wall of the insulation box is equipped with multiple heating pipes, which are evenly arrayed on the inner bottom wall of the insulation box. This device can heat and insulate the U-shaped beam while also humidifying it, largely preventing cracking and damage.

[0004] Although this application can provide insulation and humidification for U-shaped beams, the insulation tarpaulin is usually secured with clips. In winter, when the wind blows, the clips alone are not strong enough and they will be blown away along with the insulation tarpaulin. As a result, the heated water vapor emitted from the insulation box will escape into the air, and the insulation tarpaulin will not be able to trap this heated water vapor, thus reducing the insulation and humidification effects of the insulation device. Utility Model Content

[0005] To solve the above problems, this utility model proposes an antifreeze device for U-shaped beam construction, which uses the weight of the box to stabilize the insulation tarpaulin, preventing strong winter winds from blowing the insulation tarpaulin away and affecting the insulation effect of the insulation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A frost protection device for U-shaped beam construction includes a beam body covered with an insulating tarpaulin. The tarpaulin is folded down at both ends to cover the front and rear openings of the beam body. An insulating box filled with water is installed on the beam body. A heating pipe is installed inside the insulating box. At least one water inlet pipe and several steam outlet pipes are installed on the wall of the insulating box, and the water inlet pipe and steam outlet pipes are connected to the interior of the insulating box. A threaded rod is fixedly connected to the outer wall of the insulating box, and a threaded sleeve is fitted on the outer wall of the threaded rod through a threaded connection. The outer end of the threaded sleeve abuts against the inner side wall of the beam body. The device also includes a tarpaulin fixing assembly for fixing the insulating tarpaulin. One end of the tarpaulin fixing assembly is connected to the insulating box, and the other end is connected to the insulating tarpaulin, which pulls the insulating tarpaulin towards the beam body.

[0008] As a preferred option, a further technical solution to the above structure is:

[0009] The tarpaulin fixing assembly includes a fixing clip, the back of which is fixedly connected to a movable sleeve, the back of which is fixedly connected to a telescopic rod, and the other end of the telescopic rod is movably connected to a threaded sleeve.

[0010] A support plate is slidably connected to the inner wall of the movable sleeve. A sleeve is fixedly connected to the back of the support plate. A support rod is slidably connected inside the sleeve. The rear end of the support rod is connected to the insulation box. A spring is also provided at the front end of the support rod, and the front end of the spring is connected to the inner wall of the sleeve.

[0011] Compared with the prior art, the advantages of this utility model with the above structure are:

[0012] This invention utilizes the weight of the insulated box to prevent the insulated tarpaulin from being blown away by strong winds. By adjusting the fixed position of the insulated box, the tarpaulin can also be made to be closer to the beam to a certain extent, reducing the internal space covered by the tarpaulin and improving the insulation and humidification effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] like Figures 1 to 3 As shown, the present invention provides an antifreeze device for U-shaped beam construction, comprising a beam body 1 covered with an insulating tarpaulin. The insulating tarpaulin is folded down at both ends to cover the front and rear openings of the beam body 1. An insulating box 2 is provided on the beam body 1, and the insulating box 2 is filled with water. A heating pipe 5 is provided inside the insulating box 2. A water inlet pipe 3 and a steam outlet pipe 4 are provided on the wall of the insulating box 2, which are connected to the interior of the insulating box 2. A screw rod 7 is fixedly connected to the outer wall of the insulating box 2, and a threaded sleeve 6 is threadedly fitted onto the outer wall of the screw rod 7. The outer end of the threaded sleeve 6 abuts against the inner side wall of the beam body 1. The invention also includes a tarpaulin fixing assembly for fixing the insulating tarpaulin. One end of the tarpaulin fixing assembly is connected to the insulating box, and the other end is connected to the insulating tarpaulin, which pulls the insulating tarpaulin toward the beam body.

[0020] Water is stored in the insulation box 2. After the water is heated, water vapor is sprayed out. The hot steam insulates and heats the surface of the beam 1, which prevents the concrete from freezing and avoids cracking due to uneven evaporation rates between the surface and internal moisture of the concrete.

[0021] The heating element 5 can be intermittent high-temperature rapid heating or variable frequency continuous heating. At least one water inlet pipe 3, preferably located on the top wall of the insulation box 2, is used to replenish water to the insulation box 2. Several steam outlet pipes 4 can be installed to discharge atomized water vapor. The lead screw 7 can be installed only on one side of the insulation box 2 or symmetrically on both sides of the insulation box 2. The lead screw 7 and the threaded sleeve 6 are the external structure of the insulation box 2. The lead screw 7 cooperates with the threaded sleeve 6; rotating the threaded sleeve 6 causes it to move outward. The outward movement of the threaded sleeve 6 supports the insulation box 2 between the beam 1 and the insulation box 2. The threaded sleeve 6 abuts against the beam 1, thereby securing the insulation box 2 to the beam 1.

[0022] Optional, such as Figure 4 As shown, the tarpaulin fixing assembly includes a fixing clip 8, a movable sleeve 9, and a telescopic rod 10. The back of the fixing clip 8 is fixedly connected to the movable sleeve 9, the back of the movable sleeve 9 is fixedly connected to the telescopic rod 10, and the other end of the telescopic rod 10 is movably connected to the threaded sleeve 6.

[0023] The front end of the fixing clip 8 is used to fix the thermal insulation tarpaulin. The telescopic rod 10 is used to adjust the front and rear position of the fixing clip 8. The telescopic rod 10 is movably connected to the threaded sleeve 6, so that the fixing clip 8 can swing to a certain extent. When the thermal insulation tarpaulin is blown by strong wind, the fixing clip 8 is subjected to greater force by the thermal insulation tarpaulin. The fact that the fixing clip 8 can swing to a certain extent can relieve the stress.

[0024] Based on the above structure, further, such as Figure 4 As shown, a support plate 11 is slidably connected to the inner wall of the movable sleeve 9, and a sleeve 12 is fixedly connected to the back of the support plate 11. A support rod 13 is slidably connected inside the sleeve 12. The rear end of the support rod 13 is connected to the insulation box 2, and a spring 14 is also provided at the front end of the support rod 13. The front end of the spring 14 is connected to the inner wall of the sleeve 12.

[0025] Insulation box 2 can be installed at the end and middle of beam 1; see Figure 1 The fixing clip 8 extends outside the beam 1 to fix the end of the insulation tarpaulin; the spring 14 pulls the support plate 11 inward, the support plate 11 drives the movable sleeve 9, and the movable sleeve 9 drives the fixing clip 8. When a strong wind blows the insulation tarpaulin, the spring 14 resists the outward expansion force of the insulation tarpaulin and pulls the insulation tarpaulin back onto the surface of the beam 1.

[0026] refer to Figure 1 As shown below, the usage process of the antifreeze equipment for U-shaped beam construction provided by this utility model will be described in detail.

[0027] The first step is for the staff to move the insulation box 2 onto the beam 1. The insulation box 2 originally has a lead screw 7 welded on it, and the threaded sleeve 6 is screwed to the bottom of the lead screw 7.

[0028] The second step is to install the assembly of the fixed clamp 8, the movable sleeve 9 and the telescopic rod 10 onto the insulation box 2, that is, to put the upper end of the telescopic rod 10 onto the threaded sleeve 6; then install the assembly of the support plate 11, the spring 14 and the support rod 13 onto the insulation box 2, that is, to fix the rear end of the support rod 13 to the outer wall of the insulation box 2, which can be done by any existing snap-fit ​​fixing, thread fixing or other connection methods.

[0029] The third step involves the worker rotating the threaded sleeve 6 to move it outwards. The threaded sleeve 6 then abuts against the inner wall of the beam 1, thus fixing the insulation box 2 onto the beam 1. At the same time, after the threaded sleeve 6 is supported on the inner wall of the beam 1, it also provides a greater range of left and right movement for the telescopic rod 10.

[0030] In the fourth step, the staff moves the assembly of the fixed clamp 8, the movable sleeve 9 and the telescopic rod 10 outward (the telescopic rod on the right side of the box moves to the right, and the telescopic rod on the left side of the box moves to the left), and pulls the fixed clamp 8 out from the end of the beam 1 (as the telescopic rod 10 is stretched). Then, the staff grasps the sleeve 12 and pulls it out from the end of the beam 1. The sleeve 12 overcomes the tension of the spring 14 and drives the support plate 11 to move. When the support plate 11 is aligned with the movable sleeve 9, it is inserted into the movable sleeve 9.

[0031] Fifth step, release sleeve 12, spring 14 will pull sleeve 12 to make support plate 11 move backward, support plate 11 drives movable sleeve 9 to move backward, movable sleeve 9 hooks to the outer edge of beam 1.

[0032] The sixth step involves the staff covering the beam 1 with the insulating tarpaulin and then securing it with clamps 8. In low wind conditions, the clamps 8, with the help of springs 14, counteract the wind's movement of the tarpaulin; in high wind conditions, the weight of the insulating box 2 effectively stabilizes the tarpaulin, preventing it from being blown away. The tension of the springs 14 on the clamps 8 also helps to bring the tarpaulin closer to the beam 1, reducing the internal space covered by the tarpaulin and thus improving the insulation and humidification effects.
