Description

Technical Field

[0001] This application relates to the field of support systems for formwork projects in building construction, specifically to a beam and slab support system based on early removal and with multiple beam cross-sections and height differences between slabs. Background Art

[0002] Before pouring the beam and floor slab, it is necessary to first build a support structure for the beam and slab formwork that bears and supports the concrete. The commonly used support vertical poles are Ф48 steel pipes, wheel fasteners, socket fasteners, and disk fastener support vertical poles. The support structures required for beams with different positions, functions, and sizes and floor slab formworks with different height differences are also different. Therefore, it is necessary to build a beam and slab support system for different support vertical pole support structures, ensuring that different support structures can complete their own functions and can be connected and coordinated with each other. One implementation of traditional wooden formwork is commonly known as a soft beam bottom. Most of them use Ф48 steel pipes and cross fasteners as the main beam keels, use long steel pipes parallel to the beam bottom and fix them on the slab support vertical poles on both sides of the beam bottom, then place the secondary beam keels of wooden squares on the Ф48 steel pipe main beam keels on both sides, and then place and fix the beam bottom formwork on the secondary keels of wooden squares; another is commonly known as a hard beam bottom, which uses Ф48 steel pipes about 1.3 meters long on the site and cross fasteners, fixes them perpendicular to the beam bottom on the slab support vertical poles on both sides of the beam bottom, then nails the beam bottom formwork and wooden squares about 3 meters long together parallelly with nails, and then vertically places them on the Ф48 round pipe main keels. Due to the limited bearing capacity of the Ф48 round pipe, and most of the currently used Ф48 round pipes have been in use for more than 5 years, and due to natural rust and other factors, the bearing capacity has been greatly reduced. As a result, many local governments now require that the spacing of support vertical poles cannot exceed 900 mm, which has greatly increased the usage amount of support vertical poles and the labor costs for installation, removal, and transportation, etc., and also increased the difficulty of transporting materials for wall and column construction. And the biggest problem is that it is extremely difficult to fix the Ф48 round pipes at the same level with fasteners. It is very common for the height difference between fasteners to be 3 - 5 mm, and to ensure the supporting force of the fasteners, when the beam cross-section exceeds 0.1 ㎡, anti-slip fasteners need to be added under each fixed fastener. As a result, during and after the concrete pouring process, the beam structure cannot be corrected and adjusted, etc. Therefore, the construction difficulty is greatly increased, and it is very difficult for the formed concrete structure to achieve the quality of plaster-free finish;

[0003] In the construction of industrial buildings, the traditional double-support beam main keel structure is also used. The lower support beam with a length of 1650 mm or 1350 mm is selected according to the spacing of the disk-locked vertical poles on both sides of the beam. The lower support beam consists of two I-beams with an upper and lower horizontal piece width of 30 mm, a middle vertical piece thickness of about 5 mm, and a height of 80 mm, which are connected and fixed by 2 sets of limit pipes and screw components. Although its vertical bearing capacity is good, its side bearing capacity and torsional force are poor. And because the lower support beam is placed on the disk-locked sockets of the disk-locked vertical poles supporting the side plates of the beam, on the disk-locked sockets about 400-900 mm below the approximate position at the bottom of the beam, the lower support beam will extend 50-400 mm beyond the supporting vertical poles. As a result, when the floor formwork is removed, when materials such as the main and secondary keels of the floor formwork fall, they are likely to collide and damage each other. The upper support beam consists of 2 wooden squares or square pipes. The two ends of the upper support beam are placed on the U-shaped top supports on both sides of the beam bottom. The U-shaped top support is inserted into the 350-mm-long disk-locked extension section of the lower support beam. The U-shaped top support is adjusted to meet the beam elevation requirements of the upper support beam. If the beam cross-section is above 0.16 ㎡, then a 350-mm disk-locked extension section needs to be sleeved on the 350-mm disk-locked extension section that is clamped into the lower end beam, and a horizontal tie rod is used to connect the top support extension section, and then the U-shaped top support is inserted to adjust the support of the upper support beam. That is, although the traditional double-support beam has sufficient support force, it uses a lot of materials, with a total weight reaching 23-30 kg, and the installation, removal, and adjustment are cumbersome, laborious, time-consuming, and labor-intensive.
