Detailed Description
Example 1
The assembled steel bar truss floor support plate provided by the embodiment comprises a connecting structure for connecting a steel bar truss and a bottom die, and comprises two buckling pieces 1 which are in mirror symmetry, and a connecting piece 2 arranged between the two buckling pieces 1, as shown in fig. 1 and fig. 2; the fastener 1 is laterally provided with a bayonet 101 with an outward opening; the connecting piece 2 comprises a body 201, a blind hole 202 arranged at the bottom of the body 201, and a mounting rod 203 with one end fixed in the blind hole 202 and the other end penetrating through the bottom die; the end of the mounting rod 203 remote from the blind hole 202 is provided with a thread 203a which mates with a nut.
It will be appreciated that the two bayonets 101 are matched to the two lower chord bars of the truss and that the distance between the two bayonets 101 is the distance between the two lower chord bars. The bayonet 101 is preferably semi-circular and should have a radius slightly larger than the radius of the lower chord rebar that needs to be snapped in. The clamping piece 1 and the connecting piece 2 can be made of plastic materials or metal materials through integral die casting.
It will be appreciated that the blind hole 202 is an opening formed in the center of the body 201, and has a downward opening at one end and a closed end at the other end. One end of the mounting rod 203 is fixed in the blind hole 202, which means that the mounting rod 203 is mounted in the blind hole 202 by screwing, plugging or other common detachable fixing methods.
When the connecting structure is used, the connecting structures provided by the embodiment are used according to the area of the bottom die of the floor support plate. Two lower chord steel bars of the steel bar truss are respectively clamped on the two buckles 101, connecting holes are formed in positions, corresponding to the blind holes 202 and the mounting rods 203, of the bottom die, and the bottom die is fixed to a plurality of connecting structures through nuts. After the concrete pouring maintenance is finished, the nut is screwed down, the bottom die is removed, the mounting rod 203 is detached from the blind hole 202, and therefore the protrusion of the lower surface of the floor support plate is avoided, and the attractiveness is affected.
Example 2
The existing steel bar truss is characterized in that a support horizontal rib is arranged at the lower end of the lower chord steel bar. Because the horizontal rib of support exists, connection structure's lower surface is difficult to laminate with the die block upper surface completely, and the gap that exists between the two, and the concrete easily enters into the gap and solidification when pouring the concrete, and then leads to the structure of fixed die block to be difficult to dismantle when demolishing the die block.
The present embodiment is optimized based on embodiment 1, and aims to reduce the gap between the bottom surface of the connection structure and the upper surface of the bottom mold, so as to solve the problem that the concrete is solidified at the peripheral side of the mounting rod 203 in the gap, which results in difficult detachment of the mounting rod 203 at the later stage.
As shown in fig. 3 and fig. 5, in this embodiment, two rail members 3 are respectively disposed at the side ends of the two fastening members 1 away from the bayonet 101, and the connecting member 2 further includes two sliding blocks 204 disposed at two ends of the body 201 and slidably connected to the two rail members 3, respectively, and a sealing layer 205 disposed at the bottom of the body 201.
It is to be understood that the sliding connection structure of the sliding block 204 and the track member 3 is not limited to a specific structure, and any structure that can slide and lock the position may be adopted. The track member 3 and the buckle member 1 are integrally formed, the sliding block 204 and the body 201 are also integrally formed, and the material can be plastic material or metal material. The sealing layer 205 may be a rubber layer, which further improves the tightness between the lower bottom surface of the body 201 and the upper surface of the bottom mold, and prevents concrete from entering.
As a further preferred embodiment, the rail member 3 includes a top plate 301 and a bottom plate 302 provided at both upper and lower ends of one side of the clip member 1, a fixing rod 303 provided between the top plate 301 and the bottom plate 302, a control screw 304 provided at one side of the fixing rod 303 and having one end rotatably connected to the bottom plate 302 and the other end extending to the upper end of the top plate 301, and a control rod 305 provided at the top of the control screw 304; the sliding block 204 is provided with a through hole 204a penetrating through the fixing rod 303 and an internal threaded hole 204b in threaded connection with the control screw 304.
Compared with embodiment 1, the sliding locking structure between the track member 3 and the sliding block 204 provided in this embodiment can further adjust the body 201 down until the lower bottom surface of the body 201 is located at the lower end of the support horizontal rib and fully attached to the upper surface of the bottom die, thereby improving the fixing effect of the connecting structure on the bottom die, reducing the gap, and facilitating the detachment of the mounting rod 203.
As a further preference of the present embodiment, a reinforcing plate 4 is further disposed between the two rail members 3, and the reinforcing plate 4 is disposed at an upper end of the rail member 3 for reinforcing the connection strength between the two clip members 1.
Example 3
Because the die block needs a large amount of connection structure to fix, consequently need the staff to unscrew the installation pole one by one when demolishing, have the problem that complex operation, consuming time are long. Therefore, the present embodiment further provides a structure that improves the convenience of removal of the mounting lever 203 on the basis of embodiment 2, specifically including:
as shown in fig. 4 and 5, the connecting member 2 further includes an inner cavity 206 disposed in a side of the body 201 away from the opening of the blind hole 202 and communicating with the blind hole 202, and two side-open bar-shaped holes 207 disposed on both sides of the blind hole 202 and communicating with the inner cavity 206; two sides of the end part of the mounting rod 203, which is far away from the bottom die, are respectively provided with two limiting blocks 208 for being inserted into the two side-opened strip-shaped holes 207. The center of the inner cavity 206 and the center of the blind hole 202 are positioned on the same vertical line, and the minimum diameter of the inner cavity 206 is larger than or equal to the farthest distance between the two side strip-shaped holes 207.
As a further preference of this embodiment, the inner cavity 206 is a circular blind hole.
In this embodiment, the portion of the mounting rod 203 inserted into the blind bore 202 is a polished rod. When the mounting rod is used, the two limiting blocks 208 are aligned with the two side strip-shaped holes 207, the mounting rod 203 body is aligned with the blind hole 202, the mounting rod 203 body is pushed upwards into the blind hole 202, the mounting rod 203 body is pushed into the blind hole 202 continuously until all the mounting rod 203 parts provided with the limiting blocks 208 enter the inner cavity 206, then the mounting rod 203 is rotated to enable the limiting blocks 208 to be misplaced with the side strip-shaped holes 207, and at the moment, the mounting rod 203 is fixed and is difficult to take out. After the installation of the installation rod 203, the bottom die is installed through the matching of the nut and the threads 203a. When the bottom die is removed, the nut is unscrewed to remove the bottom die, then the mounting rod 203 is rotated until the limiting block 208 is aligned with the side strip-shaped hole 207 and enters the side strip-shaped hole 207, and then the mounting rod 203 is pulled down to remove the mounting rod 203.
The mounting rod 203 structure provided in this embodiment further simplifies the mounting and dismounting process and improves the construction efficiency on the basis of ensuring the mounting strength.
