Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a quick-disassembly device in the process of closing a post-casting strip of a construction engineering. Background Art

[0002] In housing construction projects, the closure of the garage settlement post-cast joint usually needs to be carried out after the main structure and secondary structure are completed and the settlement tends to be stable. The period is generally about 3 months after the main building is capped. At this time, outdoor backfill, municipal pipelines, greening and other professional constructions have been carried out simultaneously. In order to cooperate with the outdoor interspersed construction, shorten the construction period, and present the outdoor landscape effect of the project as soon as possible, the backfill and landscape engineering must be completed under the premise that the basement top plate does not have the post-cast joint closure. Therefore, most projects use prefabricated panels with steel casing to cover the post-cast joint first, and then pour concrete through the steel casing when the closing conditions are met.

[0003] However, the above method has many shortcomings. First, it is necessary to set up a steel pipe support at the bottom of the area to be poured, and then set up a wooden board on the top of the steel pipe support to seal the bottom. After the pouring is completed, the steel pipe support and the wooden board need to be dismantled again. There are many processes, much manpower and a long construction period. Second, there is a large loss during the construction process, especially the wooden board. Due to the short service life of its own material, it is necessary to constantly replace the new template. Third, since the cover plate is covered in advance in the post-casting zone, concrete can only be poured through the reserved steel casing, and the vibrating rod cannot be effectively extended into the concrete of the post-casting zone for vibration. The vibrated concrete is not dense, and there are quality risks.

[0004] In view of this, we propose a quick-disassembly device for the closing process of post-cast strips in construction projects. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] like Figure 1 As shown, this embodiment provides a quick-release device for closing the post-cast strip of a construction project, including a support rod assembly 100. Considering that the bottom of the post-cast strip is closed, a plurality of metal templates 300 are provided on the top of the support rod assembly 100. The bottom of the post-cast strip is closed by the metal template 300. At the same time, the support rod assembly 100 supports the metal template 300 to prevent the metal template 300 from falling due to gravity. In this embodiment, the metal template 300 adopts an aluminum template with a thickness of 3mm and a single piece length of 2m. Considering that the effect of vibrating after the inserted vibrator passes through the reserved steel casing is not good, a plurality of vibrators 200 are provided on the bottom of the metal template 300. Through the vibration conduction of the vibrator 200 and the inserted vibrator, the concrete in the post-cast strip is vibrated and compacted. The vibrator 200 adopts a 1.5KW attached high-frequency vibrator.

[0027] The improvement of this embodiment lies in that: by arranging a metal formwork 300 at the bottom of the post-cast strip, compared with the traditional formwork material, a standardized metal formwork 300 bracket system is adopted, which is convenient for quick installation and has good stability and safety. At the same time, the metal formwork 300 material can be customized according to the required weight and strength, so as to achieve the effect of not being easy to deform and damage and having a long service life, thereby ensuring the quality of the post-cast strip closure; by arranging a vibrator 200 at the bottom of the metal formwork 300, the concrete is compacted by using the method of cooperating the vibrator 200 with the inserted vibrator rod, thereby avoiding the problem of poor vibration effect of the inserted vibrator rod due to the reserved steel casing.

[0028] like Figure 2 As shown, considering the different construction heights on site, the support rod assembly 100 includes an upper support rod 101 and a lower support rod 102, and a thread 103 for adjusting the height of the support rod assembly 100 is provided at the connection between the upper support rod 101 and the lower support rod 102;

[0029] It should be further explained that the upper support rod 101 and the lower support rod 102 are made of Q235 steel pipes with a diameter of 48 mm. A support base is fixed to the end of the lower support rod 102 away from the upper support rod 101. The size of the support base is 150*150 mm to enhance the supporting force.

[0030] like Figure 3 As shown, in order to facilitate the assembly of the metal template 300 into a whole, the metal template 300 is provided with a flange 302, and the flange 302 has connecting holes 303 matching the size of the fasteners at a spacing of 150 mm. The fasteners are pins and pin plates. The metal templates 300 can be assembled into a whole by passing the fasteners through the connecting holes 303 of the flanges 302 of the two metal templates 300, which is simple and quick.

[0031] like Figure 4 As shown, considering that when the post-cast strip is poured with concrete, the metal formwork 300 completely bears the weight of the concrete and is prone to breakage, a plurality of back ribs 301 are cross-arranged on one side of the metal formwork 300. More specifically, the metal formwork 300 is provided with a back rib 301 at intervals of 200 mm in the width direction and 500 mm in the length direction. The back rib 301 is 20 mm wide and 20 mm high, thereby enhancing the anti-deformation strength of the metal formwork 300. In order to facilitate the installation of the vibrator 200, a bottom plate 201 is welded and fixed on the side of the back rib 301 away from the metal formwork 300. Screw holes are reserved in the bottom plate 201. The vibrator 200 is fixed to the side of the bottom plate 201 away from the back rib 301 by bolts. At the same time, in order to ensure the compaction effect of the concrete, a vibrator 200 is installed every 2 m on one side of the metal formwork 300. The power cords of all vibrators 200 are connected to a centralized control box, and the switches are uniformly controlled to prevent power shortage and motor damage.

[0032] In order to facilitate the support rod assembly 100 to support the metal formwork 300, a number of support heads 304 are symmetrically fixed on the side of the metal formwork 300 away from the post-casting strip. More specifically, a support head 304 with a diameter of 35 mm is set at a spacing of 1000 mm on both sides of the width of the metal formwork 300, and the length of the support head 304 is 150 mm. A socket is provided at the end of the upper support rod 101 away from the lower support rod 102, and the support head 304 is plugged into the socket of the upper support rod 101, so that the support rod assembly 100 supports the metal formwork 300, which is quick and convenient. Later, a laser plumb line is used to measure the verticality of the support rod assembly 100 to avoid tilting of the support rod assembly 100 during installation.

[0033] In summary, the working principle of this solution is as follows:

[0034] The worker uses a standardized climbing stool to place a 2m long single-piece metal template 300 close to the bottom of the garage roof post-casting strip, inserts the socket of the support rod assembly 100 into the support head 304 of the metal template 300, adjusts the middle thread 103 of the support rod assembly 100, adjusts the height of the support rod assembly 100 to ensure that the upper and lower sections are tightly pressed, and uses a laser plumb meter to measure the verticality of the support rod assembly 100 to ensure that the verticality of the support rod assembly 100 is ≯5mm; after the first piece of metal template 300 is installed and fixed, align the second piece of metal template 300 with the flange 302 of the first piece of metal template 300, and use pins and pins to pass through the connecting holes 303 of the flange 302 to make the two pieces of metal template 300 firmly connected, and so on, the metal template 300 and the support rod assembly 100 of the entire casting section are installed, and the high-frequency The vibrator 200 is fixed to the base plate 201 by bolts, and all vibrator power lines are connected to the centralized control box, and the switch is controlled uniformly. After the concrete of the post-casting strip is poured into the post-casting strip through the top steel casing, the high-frequency vibrator 200 is started to work. The vibration time is about 3 minutes, until the concrete fills the steel casing and no bubbles gush out. The controller 200 is turned off. After the concrete strength of the post-casting strip reaches 10% of the design strength, the high-frequency vibrator 200 is removed, the pins and pins connecting each metal template 300 are knocked off, the metal template 300 is removed, and the support rod assembly 100 is adjusted so that one end of the upper support rod 101 of the support rod assembly 100 is against the concrete. It is removed after the concrete strength of the post-casting strip reaches 100% of the design strength. After the metal template 300 is cleaned, the next construction section is started.

[0035] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0036] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
