Description

Technical Field

[0001] The invention relates to a composite plate mould capable of adjusting the spacing between steel bars. Background Art

[0002] The composite slab is an assembled integral floor slab formed by stacking prefabricated slabs and cast-in-place reinforced concrete layers. During production, a composite slab mold is required. The single body of the composite slab mold is generally in the shape of a long strip. When in use, the composite slab mold is generally first formed into a rectangular frame according to the size requirements, and then steel bars and other accessories are installed, and finally poured. Referring to Chinese patent CN112976248A, a U-shaped groove is generally provided on the composite slab mold for steel bar positioning, which results in the number and spacing of steel bars on each composite slab mold being fixed. However, in actual production, the number and spacing of steel bars in the manufactured composite slabs are different according to different engineering requirements, which results in the composite slab molds being disposable molds that cannot be reused, resulting in a waste of materials. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a composite plate mold with adjustable steel bar spacing, on which the steel bars are fixed by crimping with rubber strips, and the position and spacing of the steel bars can be adjusted at will according to needs, which is convenient and flexible and can be reused many times.

[0004] In order to solve the above technical problems, the present invention provides a composite plate mold with adjustable steel bar outlet spacing, comprising a horizontal top plate and a horizontal bottom plate which are arranged at intervals up and down and are both long strips, the horizontal top plate and the horizontal bottom plate have the same specifications and the edges on all four sides are flush with each other, a plurality of nuts arranged at intervals along the length direction are arranged at the upper position of the horizontal bottom plate corresponding to the center of its width direction, a through hole which penetrates the horizontal bottom plate in the vertical direction and matches the nut specification is arranged at the position of the horizontal top plate corresponding to each nut, a bolt matching the nut is arranged in each through hole, the threaded end of each bolt passes through the through hole from top to bottom and is screwed to the nut at the corresponding position, and the screwing end of each bolt is screwed to the horizontal top plate The upper sides of the plates are abutted against each other, and one side along the width direction of the horizontal top plate and the horizontal bottom plate is inner and the other side is outer. A long positioning strip is provided on the lower side of the horizontal top plate near its inner edge. The length direction of the positioning strip is consistent with the length direction of the horizontal top plate, and the two sides of the positioning strip in the length direction are flush with the two sides of the length direction of the horizontal top plate. A long first rubber strip that is consistent with the length and width of the positioning strip and is flush with it is provided on the lower side of the positioning strip. The lower side of the first rubber strip is horizontal, and a second rubber strip matching the first rubber strip is provided on the upper side of the horizontal bottom plate corresponding to the first rubber strip. The upper side of the second rubber strip is horizontal, and when the bolts are tightened with the corresponding nuts, the first rubber strip and the second rubber strip are tightly attached to each other in the vertical direction.

[0005] For the purpose of simple explanation, the composite slab mold with adjustable steel bar spacing described in the present invention is referred to as this mold for short.

[0006] The method of using this mold is as follows: the steel bars of this mold are arranged between the first rubber strip and the second rubber strip, and are crimped and fixed by the extrusion force from the horizontal top plate and the horizontal bottom plate. When it is necessary to adjust the spacing between the steel bars and increase or decrease the number of steel bars, it is only necessary to loosen the bolts to separate the first rubber strip and the second rubber strip. At this time, the spacing and number of steel bars can be adjusted. After the adjustment, the bolts and corresponding nuts can be tightened again.

[0007] Advantages of this mold: This mold uses rubber strip crimping to fix the steel bars. The position and spacing of the steel bars can be adjusted at will according to needs. The adjustment process is convenient and flexible. The mold can be reused many times, which effectively saves materials and reduces mold costs.

[0008] In order to achieve better use effect of this mold, the preferred solution is as follows:

[0009] Preferably, a plurality of ribs are provided between the horizontal top plate and the horizontal bottom plate and are arranged at intervals along the length direction of the horizontal bottom plate. The ribs are arranged vertically, and the length direction of the ribs is consistent with the width direction of the horizontal bottom plate. One end of the ribs in the length direction is abutted against the positioning bar, and the other end of the ribs in the length direction is flush with the outer side of the horizontal bottom plate.

[0010] The ribs bear pressure, increase mold strength and limit the position of the rubber strip.

[0011] Preferably, a limit strip is provided on the upper side of the horizontal bottom plate corresponding to the outer side of the second rubber strip, the length direction of the limit strip is consistent with the length direction of the second rubber strip, the limit strip is fixedly connected to the horizontal bottom plate, and the outer side of the second rubber strip abuts against the inner side of the limit strip.

[0012] The limit strip can play a limiting role when installing the rubber strip, and can also prevent the rubber strip from shifting when adjusting the steel bar. BRIEF DESCRIPTION OF THE DRAWINGS
