Description

Cantilever beam fixing structure

Technical Field

The utility model relates to a scaffold frame connection structure, more specifically the theory relates to a cantilever beam fixed knot constructs.

Background

The installation of the outer scaffold of tall and big building except that every layer all depends on with the building body, the bottom needs great holding power, when the scaffold is not installed to ground, need set up cantilever beam support scaffold. The cantilever beam usually adopts I-shaped steel with stronger bearing capacity, and is locked by utilizing a pull ring which is formed by bending a steel bar and is poured into a building, but the steel bar poured into the building is easy to be directly locked, so that the deformation of parts at two ends of the I-shaped steel is easy to cause. Meanwhile, only the steel bars in the concrete are poured, so that the steel bars are inconvenient to disassemble and take out, and troubles can be brought to subsequent decoration after the steel bars are left on the building bottom plate in a cutting mode.

SUMMERY OF THE UTILITY MODEL

To the not enough that exists among the prior art, the utility model aims to provide an cantilever beam fixed knot constructs has solved the problem that the pull ring is not convenient for dismantle among the prior art.

In order to achieve the above object, one of the technical solutions of the present invention is as follows:

a cantilever beam fixing structure comprises a prefabricated sleeve, a pull ring and a pressing plate; the prefabricated concrete pull ring is characterized in that a concrete layer is embedded in the bottom plate in a penetrating mode through the prefabricated sleeve, the two ends of the pull ring penetrate through the prefabricated sleeve and the pressing plate, the pressing plate tightly presses the cantilever beam on the inner side of the pull ring through nuts at the two ends of the pull ring, a bearing plate is arranged between the part, located on the other side of the concrete layer, of the pull ring and the concrete layer, reinforcing steel bars embedded in the concrete layer are arranged above the bearing plate, and the reinforcing steel bars penetrate through the inner side of.

Compared with the prior art, the technical scheme has the following beneficial effects:

through the prefabricated sleeve, the pull ring is not required to be poured in concrete in advance, and two ends of the pull ring respectively penetrate through the prefabricated sleeve to be matched with the pressing plates locked at two ends to form a closed loop to lock the cantilever beam; the pull ring and the concrete bottom plate are not directly poured together, so that the pull ring is convenient to disassemble, and the sleeve is expected to be plastic, so that the subsequent decoration process cannot be influenced after pouring and plugging even if the sleeve is inconvenient to take out in the subsequent process; the bearing plate is arranged on the other side of the concrete, so that the condition that the contact area of the pull ring and the bottom plate concrete is too small, when the stress is large, the stress surface is not enough to cause depression, and the locking of the cantilever beam is influenced can be prevented. The reinforcing steel bars are arranged above the bearing plates to increase the strength of the joints, and the reinforcing steel bars are arranged at the positions, close to the bottom, of the bottom plate, so that subsequent treatment is not hindered.

Additional advantages, objects, and features of the above-described aspects will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the above-described aspects.

Drawings

FIG. 1 is a schematic view of the installation structure of the present invention;

fig. 2 is the schematic view of the position of the cantilever beam of the present invention.

The steel plate comprises a bottom plate 1, a cantilever beam 2, a pull ring 3, a pressure plate 4, a bearing plate 5, a steel bar 6 and a wood base plate 7.

Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the technical scheme clearer and easier to understand, the technical scheme is further described in the following combined with specific embodiments:

as shown in fig. 1-2, the utility model provides a cantilever beam 2 fixed knot constructs, including the pull ring 3 of U type, the opening of pull ring 3 is up, and building bottom plate 1's concrete layer is all passed at both ends, and the opposite side at bottom plate 1 is detained to the bottom of U type, and the both ends of pull ring 3 set up clamp plate 4. The cantilever beam 2 passes through a frame formed by the pull ring 3, the pressing plate 4 and the concrete bottom plate 1 and is pressed tightly through a nut arranged at the end part of the pull ring 3. The part that pull ring 3 passed the concrete overlaps establishes the sleeve of building in advance, and the sleeve of building in advance is built on concrete bottom plate 1, and each part dismantles the back, and pull ring 3 can be taken out from concrete bottom plate 1 below, and it is convenient to dismantle. Be provided with bearing plate 5 between pull ring 3 and the concrete bottom, increased with the area of contact of concrete bottom, can not lead to the concrete surface to form the indent because of the area of contact undersize, clamp plate 4 upwards gives up and lets and influence the locking effect. The reinforcing steel bar 6 is arranged above the bearing plate 5, and the reinforcing steel bar 6 penetrates through the pull ring 3, so that the falling-off accident caused by insufficient concrete strength at the position can be prevented. After the construction is finished, the pull ring 3 and the prefabricated sleeve are taken out, and the hole and the two sides of the concrete bottom plate 1 are filled.

Further, a wood base plate 7 is arranged between the pressing plate 4 and the cantilever beam 2, the surface of the wood base plate 7, which is in contact with the cantilever beam 2, is inclined, and the inclination angle of the wood base plate is the same as that of the cantilever beam 2. Generally, when the cantilever beam 2 is installed, the cantilever beam is inclined upwards a little, so that the phenomenon that the scaffold slides outwards is avoided. However, the cantilever beam 2 and the pressing plate 4 are in line contact, even if the bottom of the pressing plate 4 is set to be an inclined plane, the effect of full contact stress is difficult to achieve, and the actual stress contact area can be greatly increased through the wooden base plate 7 padded with the bottom surfaces with the same inclination angle and the toughness effect of the wooden base plate 7, so that the best stress effect is achieved. The wood base plate 7 should be made of pine with good toughness and strength. The two sides of the cantilever beam 2 between the pull rings 3 are also wedged tightly through wood wedges. What cantilever beam 2 most adopted is the I-steel, and matter is light and intensity is high, and the utility model discloses generally the multiunit cooperation is used, fills up the space of I-steel mid portion both sides through timber and crowded tight back, both can prevent to move about cantilever beam 2, can increase cantilever beam 2's mechanical properties again.

Furthermore, the prefabricated sleeve and the bearing plate 5 are coated with an anti-sticking agent before being prefabricated, so that the prefabricated sleeve and the bearing plate are convenient to use and take out, and the prefabricated sleeve and the bearing plate do not influence the functions of the prefabricated sleeve and the bearing plate even if the prefabricated sleeve and the bearing plate are not stably poured due to the stress direction. The prefabricated sleeve is guaranteed to penetrate through the concrete bottom plate 1, the diameter of the pull ring 3 is more than 18mm, and sufficient strength is guaranteed. The inner diameter of the prefabricated sleeve is larger than the diameter of the pull ring 3, so that the insertion is convenient.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
