Specific embodiments

[0022] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0023] The present utility model discloses an auxiliary device for installing a steel bar truss floor slab, which is convenient for positioning. As Figures 1-5 shown, it includes a positioning block 1, which is used for assisting in the installation of the steel bar truss floor slab. Four universal self-locking wheels 2 are provided on the bottom surface of the positioning block 1, so that the user can adjust the position of the positioning block 1.

[0024] On one side of the outer surface of the positioning block 1, there is a fixed block 3. A second threaded rod 301 is threadedly connected to the top surface of the fixed block 3, and two telescopic rods 302 are fixedly installed on the bottom surface of the fixed block 3. The bottom surfaces of the two telescopic rods 302 are jointly fixedly installed with a mounting plate 303. The second threaded rod 301 is rotatably connected to the mounting plate 303. By rotating the second threaded rod 301, the mounting plate 303 can be pushed to rise and fall. When the mounting plate 303 rises and falls, the two telescopic rods 302 can be driven to expand and contract, so that the mounting plate 303 can contact the end of the steel bar truss and fixedly press it against the bottom plate. Extension plates 304 are provided on both sides of the mounting plate 303, and the extension plates 304 can increase the contact area with the end of the steel bar truss.

[0025] A first sliding rod 101 is fixedly installed inside the positioning block 1. Two movable blocks 103 are slidably connected to the outer surface of the first sliding rod 101, and the two movable blocks 103 can move along the first sliding rod 101.

[0026] On both sides inside the positioning block 1, first springs 102 are fixedly installed, and the two first springs 102 are both sleeved on the outer surface of the first sliding rod 101. The two first springs 102 are respectively fixedly connected to the two movable blocks 103. When the two movable blocks 103 move away from each other, the two first springs 102 will be compressed.

[0027] The top surfaces of the two movable blocks 103 are rotatably connected with contact wheels 104. One side of the outer surface of the positioning block 1 is threadedly connected with a first threaded rod 106, and one end of the first threaded rod 106 located inside the positioning block 1 is rotatably connected with a driving plate 105. The cross-section of the driving plate 105 is triangular, and the two inclined sides of the outer surface of the driving plate 105 are respectively in contact with the two contact wheels 104. When the first threaded rod 106 is rotated, the driving plate 105 will be pushed to move, so that the driving plate 105 is inserted between the two movable blocks 103, and the two movable blocks 103 will be pushed away from each other. When the driving plate 105 is pulled out from between the two movable blocks 103, the compressed first spring 102 can push the two movable blocks 103 to approach each other.

[0028] One side of each of the two positioning blocks 1 is hinged with a connecting arm 107, and the two connecting arms 107 are both hinged with the fixed block 3. When the two positioning blocks 1 move in opposite directions, the two connecting arms 107 can push the fixed block 3 to move horizontally.

[0029] One side of the extension plate 304 is fixedly installed with an insertion block 3041, one side of the extension plate 304 is fixedly installed with a fixing plate 3042, and a fixing hole 3043 is opened on one side of the fixing plate 3042. Slots 3031 are opened on both sides of the mounting plate 303, and the insertion block 3041 can be inserted into the slots 3031 to complete the installation combination between the extension plate 304 and the mounting plate 303.

[0030] One side of the mounting plate 303 is fixedly installed with a second sliding rod 3032, and an isolation block 3035 is fixedly installed in the middle of the outer surface of the second sliding rod 3032. Second springs 3034 are fixedly installed on both sides of the isolation block 3035, and the two second springs 3034 are both sleeved on the outer surface of the second sliding rod 3032. Two moving plates 3036 are slidably connected to the outer surface of the second sliding rod 3032, and a fixing rod 3037 is fixedly installed on one side of each of the two moving plates 3036. The moving plates 3036 can move along the second sliding rod 3032. When the moving plates 3036 move, the fixing rods 3037 will be driven to move.

[0031] The two moving plates 3036 are respectively fixedly connected with the two second springs 3034. When the two moving plates 3036 approach each other, the two second springs 3034 can be compressed.

[0032] The user pushes two moving plates 3036 closer to each other to compress the second spring 3034, then inserts the insertion block 3041 into the slot 3031, and releases the moving plates 3036. The compressed second spring 3034 will then push the moving plates 3036 to reset. Since the sizes of the two fixing rods 3037 are respectively the same as those of the two fixing holes 3043, the fixing rods 3037 can be inserted into the fixing holes 3043 to complete the combination of the extension plate 304 and the mounting plate 303, so as to increase the contact area with the end of the steel bar truss.

[0033] Lifting grooves 108 are formed on both sides of the outer surface of the positioning block 1. A third threaded rod 109 is rotatably connected to one side inside the lifting groove 108, and a guide rod 110 is fixedly installed on the other side inside the lifting groove 108. A placement box 111 is threadedly connected to the outer surface of the third threaded rod 109, and the placement box 111 is slidably connected to the guide rod 110. A counterweight 112 is placed inside the placement box 111. By rotating the third threaded rod 109, the placement box 111 can be lifted or lowered along the guide rod 110. When the placement box 111 descends to the installation beam of the installation floor, the counterweight 112 can be placed into the placement box 111. Due to the weight of the counterweight 112 itself, it can prevent the positioning block 1 from shifting when the end of the steel bar truss and the bottom plate are fixedly pressed.

[0034] The working principle of the present utility model is as follows: Place the positioning block 1 on the beam, and then when rotating the first threaded rod 106, it will push the driving plate 105 to move, causing the driving plate 105 to be inserted between the two movable blocks 103, which will then push the two movable blocks 103 away from each other. When the driving plate 105 is pulled out from between the two movable blocks 103, the compressed first spring 102 can push the two movable blocks 103 closer to each other, enabling the two connecting arms 107 to push the fixing block 3 to move horizontally. By rotating the second threaded rod 301, the mounting plate 303 can be pushed down. When the mounting plate 303 descends, it can contact the end of the steel bar truss and fixedly press it against the bottom plate. During this process, the two moving plates 3036 can be pushed closer to each other to compress the second spring 3034, then the insertion block 3041 is inserted into the slot 3031, and the moving plates 3036 are released. The compressed second spring 3034 will then push the moving plates 3036 to reset. Since the sizes of the two fixing rods 3037 are respectively the same as those of the two fixing holes 3043, the fixing rods 3037 can be inserted into the fixing holes 3043 to complete the combination of the extension plate 304 and the mounting plate 303, so as to increase the contact area with the end of the steel bar truss.

[0035] Although the present utility model has been described in detail above with general descriptions and specific embodiments, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
