Description

Prefabricated outer wall banding flitch fixed fixture of assembled structure

Technical Field

The utility model belongs to the technical field of the installation of assembled wall body, concretely relates to prefabricated outer wall banding flitch fixing fixture.

Background

When the prefabricated outer wall and the laminated slab are installed, the butt joint position has a negative tolerance of 10mm to form an installation seam, and the space is used for adjusting the flatness of the laminated slab. Before the outer wall and the cast-in-place section of the composite slab are cast in a rolling mode, the installation seam needs to be blocked by battens. In the existing construction, the batten is fixed by using an iron wire to hang the batten, the batten is reinforced with the steel bar of the laminated slab, and a fastening opening is nailed by a nail to prevent rotation. The construction method has the advantages that the number of reinforcing points of the iron wire is large, the steel wire is not firm, the phenomenon of die running is easy to occur when concrete is poured, and the treatment is labor-consuming and time-consuming.

SUMMERY OF THE UTILITY MODEL

The invention aims to solve the technical problems existing in the background technology.

The utility model discloses a technical means be:

a prefabricated outer wall edge sealing batten fixing clamp with an assembled structure comprises a clamping plate and a fixing screw, wherein the fixing screw is pre-embedded in a wall body when the wall body is prefabricated; the clamping plate is formed by welding an upper fixing part and a lower fixing part into a whole, the upper fixing part is a 2L-long channel steel, the lower fixing part is a 3L-long channel steel, the upper fixing part and the lower fixing part are fixedly attached to the back plate in a welding mode, the welding length is L, an included angle formed by the back face of the upper fixing part and the top face of the lower fixing part is a batten clamping position, a bolt hole is formed in the back plate of the lower fixing part, and a nut is installed on a fixing screw.

The utility model discloses become to the fixed of flitch and use the bottom spacing basis by the pressure direction from down up, from the fixed flitch of outer pressure direction of up, the limiting displacement that two directions were accepted to the flitch presses wall body and superimposed sheet contained angle position.

Preferably, L ═ 50; preferably, the hole on the lower fixing portion is a vertical long hole.

Drawings

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

FIG. 2 is a view showing an installation state of the fixing jig;

fig. 3 is a reference view showing a use state of the fixing jig.

Detailed Description

The structure of the present invention is specifically described below with reference to the accompanying drawings:

as shown in fig. 1-3, the prefabricated exterior wall edge sealing batten fixing clamp with the assembly type structure comprises a clamping plate and a fixing screw rod 3, wherein the fixing screw rod 3 is pre-embedded in a wall body when the wall body is prefabricated; the cardboard is by last fixed part 1 and lower fixed part 2 welding as an organic whole constitution, go up fixed part 1 and be long 2L's channel-section steel, lower fixed part 2 is the channel-section steel that length is 3L, goes up fixed

part

1, 2 backplate pastes welded fastening of lower fixed part, and welding length is L, goes up the contained angle that the back of

fixed part

1 and 2 top surfaces of lower fixed part constitute and is 5 solid positions of blocking for the flitch, establishes the bolt hole on the 2 backplate of lower fixed part, and 3 upper nut 4 of clamping screw.

The value of L is determined according to the size of the batten, the batten used is 50 x 80 battens, the L value of the clamping plate used in matching is 50mm, namely the length of the upper fixing part channel steel is 100mm, the length of the lower fixing part channel steel is 150mm, the two channel steels are attached to each other in a stepped mode back to back, and the contact surface is 50mm long and welded together. The height of the formed batten clamping position, which is positioned on the outer side of the batten, is 50, the height of the batten is limited by the top of the lower fixing part, the lower fixing part is provided with a bolt hole for installing a fixing screw, and the clamping apparatus is tightly attached to a wall body by screwing a nut.

The following describes the use of the present holding fixture in detail with reference to specific construction examples:

1) the prefabricated outer wall 7 of prefabricated structure top reduces 10mm, is promptly than 6 bottom elevations of superimposed sheet 10mm low, and here adopts 50mm 80mm flitch to carry out the shutoff.

2) The prefabricated outer wall 7 is prefabricated, fixing screws 3 are embedded in positions 200mm away from the top of the wall, two fixing screws are embedded in the wall at fixed positions of each batten, and the positions 200mm away from the wall edge (top edge) of the prefabricated outer wall 7 are respectively.

3) Adopt two 12 channel-section steels dislocation welding that length is 150mm and 100mm respectively to become the stairstepping cardboard, wherein 100 mm's channel-section steel is on upper portion, and 150mm channel-section steel is lower fixed part, and two channel-section steels are back-to-back welded.

4) A round hole is reserved in the channel steel of the upper fixing part and is fastened by a screw during installation; the slot steel of the lower fixing part is drilled with a long hole of 14mm by 20mm, and the embedded screw penetrates through the hole and is locked and fixed by a fastener. The slot hole makes the cardboard finely tune from top to bottom.

5) When the fixed clamp is disassembled, the lower fastener and the upper screw are disassembled, and the clamp is used in a turnover manner during the construction of the next layer.

The fixing clamp is simple to operate and high in mounting and dismounting speed, reduces the outer wall plugging construction process, and avoids the outer wall water seepage hidden danger; meanwhile, the clamp is used in a turnover mode, and cost is saved.
