[0028] Example 1
[0029] See also Figures 1 to 5 , the utility model provides an adjustable steel-wood composite device for a steel truss floor deck, comprising a mounting base detachably arranged on two H-shaped steels 2, and a steel-wood composite beam is arranged between the two mounting bases;
[0030] The mounting base includes a lower connecting member 3 with a "U"-shaped cross section. An upper connecting member 1 is detachably provided at both ends of the closed end of the lower connecting member 3. The two upper connecting members 1 are respectively located at the two side ribs of the H-shaped steel 2.
[0031] The upper connecting member 1 comprises a rectangular square tube, and a limit block is fixedly arranged on the upper surface of the square tube.
[0032] Two screws are arranged in parallel on the lower surface of the square tube, and two through holes are respectively opened at both ends of the closed end of the lower connecting piece 3. The screws pass through the through holes, and the screws extend to one end below the lower connecting piece 3 and are threadedly connected to a locking nut.
[0033] The limit block is a channel steel, which is a common building material on construction sites. It is low-cost, easy to process, and easy to promote and use. The closed end of the limit block is fixedly connected to the square tube. The groove width of the limit block corresponds to the width of the square wood 5, and one end of the square wood 5 is inserted into the groove.
[0034] The projections of the groove of the limiting block and the through groove of the square tube on the horizontal plane are perpendicular.
[0035] A cushion block 4 is arranged between the mounting base and the lower connecting member 3 .
[0036] When the utility model is used, the lower connecting member 3 and the upper connecting member 1 are fixed to the lower flange of the H-shaped steel 2 by screws, and the spacer 4 is inserted into the gap between the lower connecting member 3 and the upper connecting member 1. The spacer 4 can keep the upper connecting member 1 in a horizontal state, which is convenient for the later use of the device. The screw is locked with a locking nut, and then the two ends of the steel-wood composite beam are respectively placed on the mounting bases on both sides. Through the above process, the single set of adjustable steel-wood composite support device is erected.
[0037] According to the different spans of the rooms, different numbers of steel-wood composite support devices need to be erected. After the erection is completed, a cross bar 8 is erected on the upper part of the multiple steel-wood composite support devices to support the floor decking. The cross bar 8 is preferably made of channel steel, which is a common building material on construction sites, with low cost, easy processing, and easy to promote and use.
[0038] Example 2
[0039] On the basis of Example 1, the steel-wood composite beam includes a connecting steel 6 with a "U"-shaped cross-section, and a square wood 5 is slidably arranged at both ends of the connecting steel 6. The ends of each square wood 5 that are away from each other are detachably connected to one of the mounting bases. Wood is a natural green material, which reduces the amount of steel used and has outstanding environmental benefits.
[0040] A plurality of through mounting holes are arranged in an array on the side walls at both ends of the connecting steel 6, and a plurality of positioning holes are arranged in an array on the square wood 5. The square wood 5 is fixedly connected to the connecting steel 6 by bolts 7 that penetrate the positioning holes and the mounting holes.
[0041] A folded edge is fixedly provided at each open end of the connecting steel 6 , and the folded edge faces the middle of the connecting steel 6 .
[0042] The folded edge can limit the position of the square wood 5 , and can make the square wood 5 slide in the connecting steel 6 to prevent the square wood 5 from being separated from the connecting steel 6 .
[0043] When the square timber 5 is connected to the connecting steel 6, the length of the steel-wood composite beam can be adjusted, thereby increasing the applicable scope of the steel-wood composite beam support assembly.
[0044] Example 3
[0045] On the basis of Example 2, a number of limiters are arranged on the steel-wood composite beam, each of which includes a positioning block, which is a channel steel. A pin is fixedly arranged at the closed end of the positioning block, and the pin corresponds to the mounting hole on the connecting steel 6 and the positioning hole on the square wood 5. When the limiter is used, the pin of the limiter is inserted into the mounting hole or the positioning hole, and the cross bar 8 is placed in the groove of the positioning block. The displacement of the cross bar 8 can be effectively avoided by the limiter.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
