Detailed Description
The invention is further explained below with reference to the drawings.
Example one
The mounting tool of this embodiment, along 8 direction of wearing to establish of reinforcing bar in the middle of the last chord, the last chord of multichannel steel bar truss's the same position and web member reinforcing bar build a wear muscle pipeline, reinforcing bar 8 through wear muscle pipeline can be convenient wear to the design position, then will wear muscle pipeline and 8 separations of reinforcing bar, carry out the ligature of distribution reinforcing bar 8 at last.
The bar penetrating pipeline is formed by communicating a plurality of sections of sleeves 4, the sleeves 4 are disconnected at the crossed positions of upper chord bars of the steel bar trusses 5, each section of sleeve 4 is longitudinally positioned on the same axis, the length of each section of sleeve 4 is slightly smaller than the clear distance between the upper chord bars of two adjacent steel bar trusses 5 (a floor bearing plate 6 is produced in a factory in a standardized mode, and the distance between the steel bar trusses 5 is relatively standard), so that the tool can be smoothly positioned in place, and a through channel is formed among the upper chord bars, the lower chord bars and the web member steel bars of the steel bar trusses. Although the pipeline is arranged in sections, the reinforcing steel bars 8 can be prevented from being clamped when passing through the joint position of the adjacent pipelines by the aid of the end caps 7, and smooth passing is realized.
Before the tool is used, according to the design height of a steel bar truss 5, the vertical position of a vertical rod 3 of a sleeve 4 on a cross rod 2 is adjusted, so that the circle center of a reinforcement penetrating pipeline in place is basically coincided with the center point of a triangular section formed by an upper chord, a lower chord and a web member steel bar of the steel bar truss, and the end cap 7 is prevented from being blocked by the upper chord, the lower chord and the web member in the reinforcement penetrating process.
The outer diameter of the sleeve 4 is smaller than the minimum vertical distance from the center point of a triangular section formed by the upper chord, the lower chord and the web member steel bar 8 of the steel bar truss 5 as the circle center to the upper chord, the lower chord and the web member, and the inner diameter of the sleeve 4 is larger than the outer diameter of the distributed steel bar 8 and the diameter of the end cap 7, so that the end cap 7 can smoothly pass through a pipeline under the pushing of the steel bar 8.
The vertical rod 3 and the cross rod 2 are fastened through a nut, and the vertical rod 3 and the sleeve 4 are fixed through spot welding. The height of the sleeve 4 is ensured by adjusting the height of the vertical rod 3, so that the device is suitable for the thicknesses of floor bearing plates 6 with different specifications.
The sleeve 4 in this embodiment is C type section and has an opening in the below, and the opening width is greater than the diameter of reinforcing bar 8 and is less than end cap 7 diameter, ensures that end cap 7 can not deviate from the opening part when passing through from the pipeline of wearing the muscle. The end cap 7 is removed, and the steel bar 8 is pulled out from the opening of the sleeve 4.
The end cap 7 is in a half-round cylinder shape and is made of stainless steel or PE materials, a hole is formed in the center of the inner portion of the rear end of the cylinder, and the diameter of the hole is larger than that of a steel bar 8 to be installed.
The construction process of the floor support plate comprises the following steps:
1) Floor deck 6 laying
Hang building carrier plate 6 to the installation area, lay according to the layout of design territory, it is fixed along with spot welding with the horizontal muscle and the girder steel at 6 both ends of building carrier plate along with laying during laying, in time set up building carrier plate temporary support according to the design requirement simultaneously to ensure to support stably, reliably.
2) Distributed reinforcement 8 installation
After the floor bearing plate 6 is laid in a certain area and installed and fixed, connecting steel bars, negative bars and bottom plate distribution steel bars perpendicular to the direction of the steel bar truss 5 are installed according to design requirements (wherein the bottom plate distribution steel bars should be installed preferentially), and the floor bearing plate is connected with the steel bar truss 5 in a binding mode to form an integral stress steel bar mesh.
Wherein, the bottom plate distribution reinforcing bar of 6 directions of perpendicular building carrier plate adopts this mounting tool to install, and concrete method is:
(1) according to the design, the positions of distributed steel bars are positioned on the steel bar truss 5 and marked;
(2) the installation tool of the distributed steel bars 8 of the floor bearing plate 6 is vertical to the direction of the steel bar truss 5, the steel bar penetrating pipeline is positioned according to the position of the steel bars marked in advance, and the sleeve 4 forms a penetrating channel among the upper chord, the lower chord and the web member steel bars of the steel bar truss 5;
(3) an end cap 7 is sleeved on one end of a steel bar 8 and is arranged in the sleeve 4 in a penetrating way, the steel bar 8 is sent to a designed position, then the end cap 7 is taken off, the steel bar 8 is separated from the gap of the sleeve 4,
(4) and taking out the installation tool, and binding and fixing the steel bars 8 and the steel bar truss 5.
3) Pouring of concrete
And after all the steel bars 8 are bound, and the floor bearing plate 6 is poured with concrete after being qualified through inspection and acceptance.
The beneficial effect of mounting tool in this embodiment does:
1. in the construction of assembled building carrier plate, form a "pipeline" along 8 directions of reinforcing bar, reinforcing bar 8 can follow quick the passing in the sleeve pipe 4, deviate from, take one's place, shift out, greatly improved the efficiency of construction.
2. The sleeve 4 has two cross-section types of a round section and a notch section, and can be flexibly selected.
3. The vertical rods 3 can be vertically adjusted to be suitable for floor bearing plates 6 with different thicknesses (the height of the steel bar truss 5 is changed along with the plate thickness of the floor bearing plates 6).
4. The top end of the steel bar 8 is provided with the end cap 7, so that the steel bar penetrating pipeline formed by the sleeve 4 can be quickly and conveniently passed.
Example two
The present embodiment differs from the first embodiment described above in the structure of the sleeve 4.
The sleeve 4 of this embodiment is formed by two semicircular steel pipes through the articulated pipe clamp round pin axle, and every section of sleeve 4 is the closed condition under pipe clamp elastic force state, and the reinforcing bar 8 is sent to the design position in sleeve 4, then opens every section of sleeve 4, can conveniently make reinforcing bar 8 deviate from.
