Special auxiliary support rod assembly for prefabricated wall panels with door openings

technical field

The utility model belongs to the technical field of construction engineering, in particular to a special auxiliary support rod assembly for prefabricated wall panels with door openings.

Background technique

In the concrete prefabricated components of prefabricated buildings, if there are door openings in the prefabricated components, it is easy to crack due to the unbalanced weight of the components and the unbalanced lifting force during the production and hoisting process, resulting in cracking of the prefabricated components with door openings. In addition, prefabricated components with door openings are prone to cracking due to vehicle bumps during transportation.

At present, the method for solving the cracking of this prefabricated component with a door opening includes: using concrete braces to connect with the lower end of the door opening, and then truncate it after arriving at the construction site. The disadvantage of this method is that it causes a waste of reinforced concrete and increases the weight and work difficulty of on-site hoisting. In addition, it is not easy to cut off the construction site. waste.

The technical scheme that the utility model adopts is:

A special auxiliary support bar assembly for prefabricated wall panels with door openings, comprising a large square tube, a small square tube with one end inserted into the large square tube, a steel plate A welded and fixed to one end of the large square tube, and a steel plate B welded to one end of the small square tube. A number of screw holes are drilled on the steel plate A and the steel plate B, and a sleeve is fixed with a screw in each screw hole. The nut secures the connection in place.

In the above technical scheme, full-thread screw holes are respectively drilled on the large square tube and the small square tube, and fixed nuts are welded at corresponding positions on the steel trolley, and two full-thread screws pass through the full-thread screw holes on the large square tube respectively. And the whole thread screw hole on the small square pipe, is connected and fixed with two fixing nuts on the steel trolley downwards.

In the above technical solution, the distance between the full-thread screw holes drilled on the large square tube and the small square tube from the frame of the door opening is equal to 1/5 of the width of the door opening.

In the above technical solution, the large square tube and the small square tube are 50×50×2mm square tube and 40×40×2mm square tube respectively, and both the steel plate A and the steel plate B are steel plates with D=10mm.

In the above technical solution, the overlapping sections of the large square tube and the small square tube are fixedly connected and positioned by bolts and nuts. The groove is welded and fixed with a nut on the small square pipe, and the bolt passes through the U-shaped groove on the large square pipe from top to bottom and is connected in the nut of the small square pipe.

Working principle and remarkable effect:

(1) The components of this utility model are divided into left and right parts. The left and right parts are inserted through two kinds of square tubes with different specifications. In the prefabricated wallboard, it is ensured that the assembly of the utility model is integrated with the prefabricated component. Then, by using the full thread screw on both sides, the assembly of the utility model is fixed into one with the bottom steel trolley.

(2) When using, put the square tubes of the left and right parts first, adjust the distance to reach the size of the door opening, and fasten the connecting nut on the upper end of the bolt to ensure that the size of the components of the utility model is consistent with the size of the door opening; on the steel plates at both ends of the left and right parts, Fix the specified number of sleeves with screws respectively; then weld M16 nuts on the steel trolley surface corresponding to the opening of the square tube, put on the full-wire screw, fix the utility model assembly and the trolley as a whole, and adjust the whole Use the nut on the upper end of the screw to adjust the verticality of the end steel plate.

(3) Weld an M16 fixing nut on the steel platform directly below the fixing round holes of the left and right parts, use an M16 full-wire screw to connect and fix it with the lower fixing nut, and screw an M16 nut on the top of the screw to turn the utility model The components are fixed as a whole with the steel trolley.

(4) During the demoulding process, loosen the nut above the full-thread screw, and then loosen the full-thread screw and the fixing nut of the trolley. After removing the full-filament screw, the product can be demolded.

(5) After the prefabricated components with door openings are installed on the construction site, the components of the utility model are detachable, unscrew the screw connected to the embedded sleeve of the prefabricated components, and then loosen the connecting nuts that fix the left and right parts of the utility model , to complete the assembly and disassembly.

(6) The component device of the utility model is demoulded and hoisted until the hoisting is completed on the construction site, and after two layers of hoisting are completed, the support rod assembly of this layer can be dismantled and recycled to the factory.

The utility model provides a simple and fast auxiliary support rod assembly tooling, which avoids the risk of cracking of the prefabricated component due to unbalanced weight of the prefabricated component and uneven lifting force during the production and hoisting process of the prefabricated component with a door opening, and also avoids the risk of cracking of the prefabricated component with a door opening. The risk of prefabricated components cracking due to vehicle bumps during transportation of door opening prefabricated components. The utility model has the advantages of simple structure, easy manufacture and low cost, but it is easy to install and use, reliable in operation and good in versatility. It can be recycled after being disassembled and assembled on the construction site, and can be used in later projects only by secondary processing of the connecting holes. Realize the application of door openings with the same thickness, effectively improve the service life of the components of the utility model, save mold costs, ensure the quality of prefabricated components, and improve work efficiency.

detailed description

Referring to Fig. 1, the special auxiliary support rod assembly for prefabricated wall panels with door openings of the present utility model includes a large square tube, a small square tube with one end inserted into the large square tube, a steel plate A welded and fixed to one end of the large square tube and welded and fixed to one end of the small square tube Steel plate B, said steel plate A and steel plate B are drilled with several screw holes, and a sleeve is fixed with a screw in each screw hole. The overlapping segments of the suit are fixedly connected by bolts and nuts for positioning.

Below in conjunction with accompanying drawing, the concrete implementation of the present utility model is described further:

The utility model uses square tubes of two sizes to ensure that the small square tube can be inserted into the inner hole of the large square tube. Generally, 50×50×2 and 40×40×2 square tubes are used, and the two ends of the square tube are 1/5 of the length of the door opening. Drill a Ø18mm hole at the position, and weld a D=10mm steel plate at both ends, the width is generally 200mm, and the height is consistent with the thickness of the component; when the outer size of the two steel plates reaches the width of the door opening, drill the length of M16 on the square tube at the center position 12mm U-shaped hole, welding M16 fixing nuts on the small square tube; place two H=80mm sleeves at both ends during use (the thickness of the component is low, you can change it to place a sleeve at each diagonal corner), adjust the length of the utility model assembly Keep consistent with the door opening, use M16 nuts and M16 large gaskets to lock the assembly tooling of the utility model. The M18 holes at both ends pass through an M16 full-wire screw. Weld an M16 nut on the steel trolley to fix the screw. At the same time, screw an M16 nut on the upper end to adjust the verticality of the steel plates on both sides. It is completely fixed with the trolley.

The use of this auxiliary support rod assembly can effectively form a whole with the component because it has been installed in place before the component is poured and tamped, so it can effectively solve the cracking of the component during production, hoisting and transportation engineering.
