Description
Technical Field
[0001] The present application relates to the field of turnover material accessories for formwork engineering in building construction, and specifically to a combined main beam keel support structure. Background Art
[0002] Before pouring beams, a beam formwork structure must be constructed to bear and support the concrete. To ensure effective beam support, support columns, primary beam keels, and secondary beam keels are installed on both sides and below the beam formwork structure. In existing construction processes, the beam bottom support structures in traditional wooden formwork mainly come in two types: soft beam bottom and hard beam bottom. Most of the time, the bottom support structure of the beam uses a soft beam bottom, which uses Φ48 steel pipes and cross fasteners as the main beam keel. When setting up, first place the steel pipe parallel to the bottom of the beam and fix it on the plate support vertical poles on both sides of the bottom of the beam. Then place the wooden secondary keel of the beam bottom on both sides of the Φ48 steel pipe main keel, and then place and fix the beam bottom template on the wooden secondary keel; the hard beam bottom uses about 1.3 meters of Φ48 steel pipes and cross fasteners at the construction site as the main beam keel. The vertical beam bottom is fixed to the plate support vertical poles on both sides of the beam bottom. Then, connect the beam bottom template with the wooden square about 3 meters long with parallel nails, and then place it vertically on the Φ48 round tube main keel. Due to the limited bearing capacity of Φ48 round tubes, and the fact that most of the Φ48 round tubes currently in use have been in use for more than 5 years, their bearing capacity has been greatly reduced due to factors such as natural rust. As a result, many places now require that the spacing between support poles cannot exceed 900mm, which greatly increases the use of support poles and the labor costs for installation, removal and transportation, and also increases the difficulty of transporting materials for wall column construction. The biggest problem is that the fastener fixation can easily make the Φ48 round tubes at the same level. It is common to have a height error of 3 to 5mm between fasteners. In order to ensure the supporting force of the fasteners, when the beam cross-section exceeds 0.1㎡, it is necessary to add anti-slip fasteners under each fixed fastener. As a result, it is difficult to correct and adjust the beam structure during and after the concrete pouring process, which greatly increases the difficulty of construction, and the concrete structure after forming is also difficult to achieve the quality of being free of plastering.
[0003] In the construction of industrial plants, the traditional double-joist main keel structure is also used. According to the spacing between the buckle columns on both sides of the beam, a 1650mm or 1350mm long lower joist is selected. The lower joist is composed of two upper and lower horizontal pieces with a width of 30mm, a middle vertical piece with a thickness of about 5mm and a height of 80mm. It is connected and fixed with two sets of limit tubes and screw assemblies. Although its vertical bearing capacity is very good, its lateral bearing capacity and torsional force are relatively poor; its lower joist is placed on the plate support columns on both sides of the beam and on the buckle tray 400 to 900mm below the bottom of the beam. When setting, the lower joist will extend out of the supporting column. The rod is 50 to 400 mm, so when the floor formwork falls, it is easy to collide with it and cause mutual damage; the upper supporting beam is composed of two wooden squares or square tubes. The two ends of the upper supporting beam are placed on the U-shaped top supports on both sides of the bottom of the beam. The U-shaped top support is inserted into the 350 mm long disc buckle extension section of the lower supporting beam. The U-shaped top support is adjusted to meet the beam elevation requirements of the upper supporting beam. If the beam cross-section is more than 0.16 m2, it is necessary to insert a 350 mm disc buckle extension on the 350 mm disc buckle extension section that is inserted into the lower end beam, and connect the top support extension section with a horizontal tie rod, and then insert the U-shaped top support to adjust the support of the upper supporting beam. In summary, although the traditional double-beam method can provide sufficient support force, it requires more materials when setting up, making its overall weight reach 23 to 30 kg, and the installation, removal and adjustment methods are relatively cumbersome, labor-intensive, time-consuming and labor-intensive, which greatly reduces the efficiency of use and increases the cost of use.

[0032] Example
[0033] like Figure 1 As shown, a combined main beam keel support structure is arranged on two supporting uprights, including a main beam keel portion 100, a fixed connection structure 200 arranged on the main beam keel portion 100, and a pin 300 arranged on the main beam keel portion 100.
[0034] A limited support structure 400 is also provided on the main keel portion 100 of the beam.
[0035] like Figure 2 As shown, the main beam keel portion 100 is composed of two parallel main beam keel bodies 101; each of the main beam keel bodies 101 is also provided with at least two fixing holes 102 and three horizontally arranged pin slots 103; the positions of the fixing holes 102 and the pin slots 103 provided on the two main beam keel bodies 101 correspond to each other.
[0036] The first fixing hole 102 is set at a position close to the right end of the main beam keel body 101 and adjacent to the right supporting upright, and the fixing hole 102 is located between the two supporting uprights; the second fixing hole 102 is set at any position on the main beam keel body 101 between the two supporting uprights.
[0037] One of the pin slots 103 is arranged at a position close to the right side of the main beam keel body 101 and adjacent to the right supporting upright, and the pin slot 103 and the first fixing hole 102 are respectively located on both sides of the supporting upright; the other two pin slots 103 are arranged on the left side of the main beam keel body 101 and adjacent to the left supporting upright, and the two pin slots 103 are respectively located on both sides of the left supporting upright.
[0038] A plug 104 is provided at each end of the main beam keel body 101 , and a pull ring is also provided on the plug 104 .
[0039] The plug is made of rubber material. Setting the plug can not only effectively prevent the main beam keel from being deformed due to collision, but also effectively prevent the main beam keel from damaging other components when it collides with other components. At the same time, it can also effectively prevent construction workers from being injured due to collision at the end of the main beam keel, which greatly improves the safety of the product and greatly extends the service life of the product.
[0040] like Figure 3As shown, the fixed connection structure 200 consists of a limiting sleeve 201 located between two matching fixing holes 102 on the two main beam keel bodies 101, a fixing bolt 202 that passes through the two matching fixing holes 102 on the two main beam keel bodies 101 and the limiting sleeve 201 set between the two fixing holes 102, and a fixing nut 203 that is sleeved on the fixing bolt 202.
[0041] like Figure 4 As shown, the latch 300 is composed of a trapezoidal pin piece 301, an outwardly protruding limiting piece 302 arranged on the left or right side of the rear end of the trapezoidal pin piece 301, and a fastening pin groove 303 arranged near the front end of the trapezoidal pin piece 301; a small pin piece matching it is also arranged in the fastening pin groove 303.
[0042] The fastening pin groove 303 is parallel to the right-angled side of the trapezoidal pin piece 301 .
[0043] The product is fixed by using a combination of a pin and a small pin. The fixation can be completed by simply hammering the small pin with a hammer, which greatly reduces the difficulty of fixing the product, improves the installation efficiency of the product, and better improves the efficiency of construction.
[0044] The right-angled edges of the trapezoidal pin are chamfered, making the corners of the trapezoidal pin more rounded, thereby avoiding scratches on workers during use and further improving the safety of the product.
[0045] like Figure 5 As shown, the limiting support structure 400 is composed of a U-shaped platform 401 with an opening downward, a baffle 402 vertically arranged on the left or right side of the U-shaped platform 401 and extending upward above the top surface of the U-shaped platform 401, a fastening bolt 403 that passes through the front side or rear side of the U-shaped platform 401 and is threadedly connected to the U-shaped platform 401, and a tightening plate 404 arranged at the end of the fastening bolt 403 and located between the front side and the rear side of the U-shaped platform 401.
[0046] The distance between the front side and the rear side of the U-shaped platform 401 is greater than the sum of the thickness of the two main beam keel bodies 101 , the length of the limiting sleeve 201 , and the thickness of the tightening plate 404 .
[0047] During the setting, first fix the two main beam purlins through the fixed connection structure to form a pre-assembled main beam purlin, then tilt the pre-assembled main beam purlin and place it between the two supporting uprights, so that the two supporting uprights are located between the two main beam purlins and then lay the pre-assembled main beam purlin flat, then insert the pins into the corresponding pin slots, and finally set the limiting support structure according to the position of the secondary purlin to be supported.
[0048] It should be noted that when the latch is set, the right-angled side of the trapezoidal pin piece needs to be close to the support pole. After the latch is tightened, the right-angled side of the trapezoidal pin piece can effectively embed into the screw thread of the support pole, thereby effectively locking the product as a whole on the support pole. This setting method effectively prevents the product from sliding along the support pole. At the same time, it can replace a horizontal tie rod set between the two support poles to complete the tensioning of the two support poles. Therefore, the space required for the installation of a horizontal tie rod between the two support poles can be saved, which greatly increases the operating space between the two support poles and reduces the difficulty of subsequent construction for construction personnel.
[0049] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
[0050] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model. Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
