[0002] Truss: A structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods, generally with triangular units. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared with solid beams.

[0003] Trusses are the most widely used in the construction of house roofs. Trusses are installed on the floor deck at equal distances through fasteners, and then the trusses are mounted on the wall. The floor deck forms a pouring space, allowing the roof to be formed in one piece through concrete pouring. It has the advantages of convenient construction, high strength and stability, and strong bearing capacity.

[0004] According to the different sizes of floor decking, trusses of corresponding sizes should be selected. Since the installation of trusses and floor decking needs to be completed by fasteners, traditional fasteners are of an integrated structure. One type of fastener can only be applied to trusses of corresponding sizes, with a narrow application surface and high procurement and installation pressure. In addition, in order to accurately install the truss on the floor decking, it is necessary to use a ruler to measure before the truss can be accurately placed on the floor decking.

Vertical plates 8 are vertically installed at the front and rear ends of the right side of the upper surface of the base 1, and first guide rods 9 are transversely installed at the front and rear ends of the right side wall of the first support plate 4. The outer wall of the first guide rod 9 is sleeved with a second support plate 10 that can slide left and right, and the top of the second support plate 10 is in the shape of a step platform. The floor decking plate 2 is supported by the first support plate 4 and the second support plate 10. The first guide rod 9 is provided with a scale on the outer wall for measuring the distance between the first support plate 4 and the second support plate 10, so as to facilitate the placement of floor decking plates 2 of various specifications. The second support plate 10 is provided with rollers 11 capable of rolling left and right in the slideway 6 at both ends of the front and rear ends of the bottom. The first guide rod 9 is sleeved with a locking sleeve 12 fixedly connected to the second support plate 10 on the outer wall. The locking sleeve 12 is screwed with a positioning bolt 13 on the outer wall. The positioning bolt 13 is screwed on the first guide rod 9 to squeeze the first guide rod 9, so as to position the second support plate 10. A plurality of fasteners 14 are clamped on the bottom of the truss 3 from left to right, and the fasteners 14 are screwed on the floor decking plate 2 by screws.

When the lead screw 59 rotates clockwise or counterclockwise, the thread rotation force of the lead screw 59 drives the lead screw nut 511 to move forward and backward, and the lead screw nut 511 pulls the telescopic link 56 to extend or shorten, thereby gradually increasing or decreasing the distance between the moving rods 54.

[0028] As a preferred solution, further, the rotating assembly 58 includes a rotating shaft 581 mounted on the bottom end of the front side of the first mounting plate 51 through a bearing, and a knob 582 and a second gear 583 are respectively mounted on the front and rear ends of the rotating shaft 581, and the first gear 510 is meshed and connected with the second gear 583, and the transmission ratio is greater than 1. When the second gear 583 is driven to rotate by the knob 582, the speed of the first gear 510 is increased, which is convenient for the staff to operate. A dial sleeved on the outer wall of the knob 582 is installed on the front side of the first mounting plate 51. 584, a gear position is set on the front of the dial 584 for marking the angle of the knob 582, so as to adjust the length of the telescopic connecting rod 56 and position the installation of the truss 3 on the floor decking plates 2 of different sizes. A plurality of slots 585 are equidistantly arranged on the inner wall of the dial 584 along the circumferential direction, and the positions of the slots 585 correspond to the gear positions of the dial 584. A spring 586 and a ball 587 are respectively inserted into the inner cavity of the knob 582 from the inside to the outside. The elastic force of the spring 586 pushes the ball 587 to insert into the inner cavity of the slot 585 to position the knob 582.

[0029] As a preferred solution, further, the fastener 14 includes a first buckle 141 and a second buckle 142 that are clamped at the bottom of the truss 3. The inner tops of the first buckle 141 and the second buckle 142 are inclined surfaces, which facilitate the first buckle 141 and the second buckle 142 to be sleeved on the truss 3. The inner bottom end of the first buckle 141 is provided with a slot 143 along the front-to-back direction. The upper and lower inner walls of the slot 143 are provided with upper and lower anti-slip grooves 144 that are equidistant from front to back. The anti-slip grooves 144 are triangular, and the rear surface is vertical. Directly, an insertion rod 145 connected to the inner cavity of the slot 143 is installed at the bottom end of the front side of the second buckle 142, and the anti-slip groove 144 allows the insertion rod 145 to have multiple installation points. The outer wall of the insertion rod 145 is provided with two installation grooves 146 opposite to each other up and down. The inner wall of the installation groove 146 is clamped with a spring piece 147. The spring piece 147 is arranged at an angle and is inserted into the anti-slip groove 144 under the action of its own elastic force. The spring piece 147 presses on the vertical surface of the anti-slip groove 144 to prevent the second buckle 142 from separating from the first buckle 141.

[0030] Working principle:

[0031] Step 1: Screw the positioning bolt 13 away from the first guide rod 9 to release the positioning of the second support plate 10. Under the rolling of the roller 11, the second support plate 10 is moved left and right. Under the reference of the scale, the distance between the first support plate 4 and the second support plate 10 is adjusted to meet the support requirements of the current size of the floor decking 2. Then, the positioning bolt 13 is screwed to position the second support plate 10 to complete the position adjustment of the second support plate 10. According to the indication of the positioning mark 15, the floor decking 2 is accurately placed on the first support plate 4 and the second support plate 10 to achieve the placement of the floor decking 2.

[0032] Step 2: According to the specifications of the floor deck 2, the knob 582 is rotated clockwise or counterclockwise to rotate the knob 582 to the upper gear position of the corresponding dial 584. The elastic force of the spring 586 pushes the ball 587 to insert into the corresponding slot 585 to position the knob 582. Under the transmission of the second gear 583 and the first gear 510, the lead screw 59 is rotated counterclockwise or clockwise. The threaded rotation force of the lead screw 59 drives the lead screw nut 511 to move backward or forward. The telescopic connecting rod 56 is shortened or extended. The telescopic connecting rod 56 pulls the moving rod 54 to slide along the outer wall of the second guide rod 53, changing the spacing of the laser light 55 on the moving rod 54. The laser light 55 emits a red laser to the floor deck 2 to position the truss 3, so that the truss 3 can be accurately placed on the floor deck 2.

[0033] Step three, insert the rod 145 into the slot 143, so that the first clip 141 and the second clip 142 are sleeved on the truss 3. As the rod 145 enters the slot 143, the spring piece 147 can bend inward elastically and will not hinder the movement of the rod 145 until the first clip 141 and the second clip 142 lock the truss 3. The spring piece 147 is inserted into the inner cavity of the anti-slip groove 144 under the action of its own elastic force. The spring piece 147 prevents the second clip 142 from falling off, and the truss 3 can be locked on the floor decking 2 with screws, thereby realizing the positioning and installation of the truss 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
