Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a fixing device for the core panel portion of a full concrete exterior wall. Background Technology

[0002] As people's living standards improve, their pursuit of a better life also increases, and their requirements for the quality of housing gradually rise. To improve building quality, prefabricated aluminum formwork construction technology is now widely used in building construction. However, machine room floors are usually constructed using cast-in-place concrete, which means that the standard floor aluminum formwork cannot be used. The machine room floor needs to be equipped with additional wooden formwork and a full-span support frame for construction, which leads to additional construction costs, such as steel pipe rental fees, and increases project costs.

[0003] The existing fixing devices for the core panel section of the all-concrete exterior wall increase the cost of additional scaffolding materials such as rented steel pipes and fasteners, reduce the turnover rate of aluminum formwork, and increase construction time and cost. Utility Model Content

[0004] This application provides a fixing device for the core panel section of a full concrete exterior wall, which solves the problem that existing fixing devices for the core panel section of a full concrete exterior wall increase the cost of additional rental of steel pipes and fasteners, reduce the turnover rate of aluminum formwork, and increase construction time and cost.

[0005] This application provides a fixing device for the core panel section of a full concrete exterior wall, including several sets of aluminum templates. Several sets of side holes are opened on the surface of the aluminum templates. Several sets of main keels pass through the inside of the side holes. Several sets of secondary keels are provided at the bottom of the main keels. Two sets of wooden templates are provided at the bottom of the secondary keels.

[0006] Preferably, the main keel is made of 14mm diameter steel scrap, and the secondary keel is made of 40*90mm timber.

[0007] Preferably, each of the aluminum templates in one group is provided with a single support base at both ends, and a fixing sleeve is fixedly connected to the bottom of the single support base.

[0008] Preferably, a support rod is fitted inside the fixed sleeve, and one end of the support rod is slidably connected to a support sleeve rod.

[0009] Preferably, a threaded hole is provided on one side of the support sleeve rod, and a threaded bolt is threadedly connected inside the threaded hole. A limiting hole adapted to the threaded bolt is provided on one side of the support rod.

[0010] Preferably, the bottom surface of the aluminum formwork is provided with a reinforced concrete floor slab, and a pin is inserted into the inside of the side hole, with a pin plate inserted into one end of the pin.

[0011] Preferably, a fixing plate is fixedly connected to the top end of the support sleeve rod, and the surface of the fixing plate has four sets of mounting holes.

[0012] Beneficial effects:

[0013] Considering that the existing fixing devices for the core panel section of the all-concrete exterior wall increase the cost of additional scaffolding materials such as rented steel pipes and fasteners, reduce the turnover rate of aluminum formwork, and increase construction time and costs, the following issues arise.

[0014] By using aluminum formwork, side holes, main joists, secondary joists, and wooden formwork, during installation, the position of the side holes on the aluminum formwork is adjusted according to the requirements of the aluminum-wood combined construction method and the thickness of the wooden formwork during the detailed stage. For the wooden formwork, scrap steel bars are used as the main joists and timber as the secondary joists. During the erection process, scrap steel bars from the construction process are used to pass through the side holes of the aluminum formwork as the main joists for formwork support, according to the design spacing. Then, timber is laid on the main joists at the required spacing as the secondary joists for formwork support. Finally, wooden formwork is laid on top of the secondary joists. After the main joists, secondary joists, and wooden formwork at the aluminum-wood combined section are installed, it is ensured that the wooden formwork and aluminum formwork are flush. By using aluminum formwork support instead of full-span scaffolding, the need for additional rental of steel pipes and fasteners is avoided, improving the turnover rate of aluminum formwork, reducing construction time, and lowering construction costs.

[0029] This utility model provides, for example Figure 1-4 The device shown is a fixing device for the core board part of a full concrete exterior wall, including several sets of aluminum templates 1. Several sets of side holes 2 are opened on the surface of the aluminum templates 1. Several sets of main keels 3 pass through the inside of the side holes 2. Several sets of secondary keels 4 are set at the bottom of the main keels 3. Two sets of wooden templates 5 are set at the bottom of the secondary keels 4.

[0030] The main keel 3 is made of 14mm diameter steel scrap, and the secondary keel 4 is made of 40*90mm timber.

[0031] The main keel 3 is a 14mm diameter steel bar waste generated during the construction process. The steel bar is inserted into the side hole 2 of the aluminum formwork 1, with each end extending 50mm beyond the side hole of the aluminum formwork 1. One steel bar is arranged at a spacing of 200mm, serving as the main support structure to bear the load.

[0032] One of the aluminum templates 1 has a single support base 6 at both ends, and a fixed sleeve 7 is fixedly connected to the bottom of the single support base 6.

[0033] Single support bases 6 are set at both ends of aluminum template 1 to provide support fixing points, and fixing sleeves 7 fix support rods 8 to ensure support stability.

[0034] The fixed sleeve 7 has a support rod 8 inside, and one end of the support rod 8 is slidably connected to the support sleeve 9.

[0035] The support rod 8 is telescopic and adjustable to provide height support; the support sleeve 9 is slidably connected to the support rod 8 to achieve length adjustment.

[0036] The support sleeve 9 has a threaded hole on one side, and a threaded bolt 10 is threaded inside the threaded hole. The support rod 8 has a limiting hole that matches the threaded bolt 10 on one side.

[0037] The threaded bolt 10 locks the support rod 8 in position through the threaded hole and the limiting hole to prevent slippage.

[0038] Among them, the bottom surface of the aluminum formwork 1 is provided with a reinforced concrete floor slab 11, and a pin 12 is inserted into the side hole 2, with a pin piece 13 inserted into one end of the pin 12.

[0039] The reinforced concrete floor slab 11 serves as the building support foundation. The pin 12 is inserted into the side hole 2 to fix the position of the aluminum formwork 1. The pin piece 13 is inserted into one end of the pin 12 to prevent the pin 12 from falling off.

[0040] The top end of the support sleeve 9 is fixedly connected to a fixing plate 14, and the surface of the fixing plate 14 has four sets of mounting holes.

[0041] The fixing plate 14 fixes the support sleeve 9 and is installed and positioned through the mounting holes to enhance overall stability.

[0042] Working principle: During the installation of the core panel fixing device for the all-concrete exterior wall, the aluminum formwork 1 is adjusted according to the requirements of the aluminum-wood combination construction method and the thickness of the wooden formwork 5 during the detailed stage. The side holes 2 on the aluminum formwork 1 are adjusted. The wooden formwork 5 uses steel scrap as the main keel 3 and timber as the secondary keel 4. During the erection process, steel scrap used in the construction process is passed through the side holes 2 of the aluminum formwork 1 to serve as the main keel 3 for formwork support, according to the design spacing. Then, timber is laid on the main keel 3 according to the spacing requirements as the secondary keel 4 for formwork support. Finally, the wooden formwork 5 is laid on top of the secondary keel 4. After the main keel 3, secondary keel 4 and wooden formwork 5 of the aluminum-wood combination part are installed, it is ensured that the wooden formwork 5 and the aluminum formwork 1 are flush. By using aluminum formwork 1 to support the replacement of full-span scaffolding, the additional rental of steel pipes and fasteners is avoided, the turnover rate of aluminum formwork 1 is improved, the construction time is reduced, and the construction cost is reduced.
