DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 2 A transverse telescopic support mechanism for the bottom back rib of a beam formwork comprises a transverse brace 1, which is a rectangular tube. Nuts 2 are rotatably provided at both ends of the transverse brace 1. Each nut 2 is screwed onto an outrigger 3. The outrigger 3 cooperates with the transverse brace 1 in the circumferential upper limit position. A support seat 4 is provided at the outer end of the outrigger 3. The support seats 4 at both ends are respectively in contact with the side formwork 5. When the nut 2 is rotated, the nut 2 drives the outrigger 3 to move outward, and the outrigger 3 does not rotate circumferentially during the outward movement.

[0019] It can be understood that in the above technical solution, the utility model can rotate the nut 2 to make the outrigger rod 3 drive the support seat 4 to move outward, thereby supporting the side formwork 3 and strengthening the supporting strength of the side formwork 3. Moreover, it has a simple structure, is easy to disassemble and assemble, and is very practical.

[0020] Continue reading Figure 1 and Figure 2In one embodiment of the present invention, the support seat 4 includes a vertically connected support seat horizontal portion 400 and a support seat vertical portion 401. The support seat 4 can be placed at a right angle between the bottom template 6 and the side template 5. The support seat horizontal portion 400 is located at the upper end of the support seat vertical portion 401, which is used to abut against the bottom template 6. The support seat vertical portion 401 is located outside the support seat horizontal portion 400, which is used to abut against the side template 5.

[0021] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, a plurality of baffle assemblies are arranged at intervals along the length direction of the upper side of the cross brace 1, and each baffle assembly includes two oppositely arranged baffles 7, and a groove is formed between the two baffles 7 for cooperating with the bottom back rib 8.

[0022] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the baffle 7 includes a baffle horizontal portion 700 and a baffle vertical portion 701 that are matched and connected. The baffle horizontal portion 700 is connected to the cross brace 1, and the baffle vertical portion 701 is located at the upper end of the baffle horizontal portion 700 and is connected to the side of the bottom back rib 8.

[0023] The number and position of the baffle components can be adjusted according to the actual situation of the bottom back rib 8.

[0024] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the nut 2 has a handle 200 , and the handle 200 is provided to facilitate the rotation of the nut 2 .

[0025] The rotational engagement between the nut 2 and the cross brace 1 can be achieved in the following manner: the nut 2 is divided into two parts. One part is sleeved onto the end of the cross brace 1. The inner wall of this part engages with the outer wall of the cross brace 1 via a circular groove and a circular protrusion, thereby achieving axial position limitation and circumferential rotational engagement. The other part of the nut 2 has an internal thread, which extends beyond the end of the cross brace 1 and is threadedly engaged with the extension rod 3. This is a well-known technique and will not be described in detail.

[0026] Among them, the circumferential limiting cooperation between the outrigger rod 3 and the cross brace rod 1 can be achieved in the following way: the outer end of the outrigger rod 3 is a screw structure (the part connected to the nut 2), the inner end (the end inserted into the cross brace rod 1) has a sliding groove arranged axially on the side wall, and the inner wall of the tube hole of the cross brace rod 1 is provided with a convex strip axially, and the convex strip is slidably cooperated with the sliding groove, thereby limiting and preventing the outrigger rod 3 from circumferential rotation relative to the cross brace rod 1.

[0027] When in use, the support mechanism of the present invention is placed between the two side templates 5, so that the baffle assembly cooperates with the bottom back rib 8, and then the nuts 2 at both ends are rotated to drive the outward extension rod 3 to move outward through the screwing action, so that the outward extension rod 3 drives the support seat 5 to move outward and resist against the corresponding side template 5. The support mechanism is used to support the side template and also supports the bottom back rib 8.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
