Description

Hogging moment steel bar split heads with limiting function

Technical Field

The utility model relates to a building engineering cast in situ concrete floor job site field, concretely relates to negative moment reinforcing bar split heads of taking limit function.

Background

At present, the requirements on the quality of construction engineering are more and more strict, wherein the thickness of a hogging moment reinforcement protective layer of a cast-in-place floor slab, the position of a reinforcement and the thickness of the floor slab are the most important to control in the construction stage of a main body structure. The finished split heads used at present can only meet the thickness of a negative moment rib protective layer when steel bars are bound, in the process of pouring concrete, the position of the negative moment rib of a cast-in-place concrete building is changed due to the fact that personnel trample, concrete pump pipes, vibrating rods and other equipment disturb, the position of the negative moment rib cannot be guaranteed, when the floor slab poured concrete is leveled, the thickness of the floor slab cannot be directly guaranteed, the thickness of the poured concrete is generally controlled through measuring elevation, and therefore the thickness of the negative moment rib protective layer is indirectly controlled. The construction of making level like this needs the continuous act as go-between of workman, and reduce efficiency causes the error moreover easily, in case make level the error and appear, can cause cast-in-place concrete floor thickness unable assurance to cause the unable assurance of negative moment muscle protective layer thickness.

Disclosure of Invention

To the problem, the utility model discloses a take limit function's hogging moment reinforcing bar split heads, this split heads set up the recess, and the hogging moment muscle is in the recess of split heads, and vertical and horizontal position that whether personnel trample still equipment can all ensure the hogging moment muscle can not change.

In order to realize the technical purpose, the utility model adopts the following technical scheme:

the utility model provides a take limit function's hogging moment reinforcing bar split heads, supports including the at least two sets of split heads that are parallel to each other, and every split head of group supports all including a plurality of support element, and the mutual parallel arrangement of a plurality of support element with the group, and the support element that adjacent two sets of split heads supported is the mode setting of one-to-one, and a plurality of support element tops of every group are connected with split head horizontal muscle jointly, split head horizontal muscle is provided with at least one recess that is used for placing the hogging moment reinforcing bar between adjacent support element.

Preferably, the supporting unit has a herringbone structure.

Preferably, the distance between two adjacent groups of split heads is less than 1 m.

Preferably, the pitch of adjacent support units is not greater than 2 times the pitch of adjacent grooves.

Preferably, the depth of the groove is smaller than the height of the support of the split heads.

Preferably, the groove is a U-shaped groove.

The beneficial effects of the utility model

The utility model discloses because the hogging moment muscle is in the recess of split heads, whether personnel trample still the disturbance of equipment can't change the vertical and horizontal position of hogging moment muscle all. When the cast concrete floor is leveled, the thickness of the floor is strickled by a trowel according to the height of the split heads, so that the thickness of the cast-in-place slab, the negative bending moment rib protective layer and the negative bending moment rib position can meet the requirements, the construction is convenient, the construction efficiency is improved, and the construction quality is ensured.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the terms "inside", "outside", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The utility model discloses a hogging moment reinforcing bar split heads as shown in fig. 1-3 of taking limit function, this split head include that two sets of split heads that are parallel to each other support 2, and the interval between two sets of split heads supports is less than 1 m. Every group split heads supports all including a plurality of support element, this support element welds into chevron shape structure for diameter 6 mm's reinforcing bar, split heads horizontal muscle 1 is connected jointly to a plurality of support element tops of every group, this horizontal muscle is diameter 8 mm's reinforcing bar, a plurality of support element along split heads horizontal muscle's axis with the group are equidistant interval distribution, support element and split heads horizontal muscle 1 welding, split heads horizontal muscle sets up two U type recesses between adjacent per two support element, this recess can be that a reinforcing bar bends to make, also can be that the welding of multistage reinforcing bar constitutes. The width value of the groove is 2mm larger than the diameter of the designed negative-bending-moment reinforcing steel bar, the depth value of the groove is equal to the diameter of the negative-bending-moment reinforcing steel bar plus the thickness value of the protective layer, the depth of the groove is smaller than the height supported by the split heads, and the distance between every two adjacent supporting units is not larger than 2 times of the distance between every two adjacent grooves. The quantity of the grooves in the horizontal ribs above the two groups of split heads is equal, namely, a plurality of supporting units supported by the two groups of split heads are arranged in a one-to-one corresponding mode, the grooves of the two groups of horizontal ribs are also arranged in a one-to-one corresponding mode, the negative bending moment ribs 3 are arranged in the grooves of the two adjacent horizontal ribs, and the negative bending moment ribs are arranged in parallel.

The thickness of the floor is determined according to the design, the height of the split heads is 1mm smaller than the thickness of the floor, the split heads can be covered by concrete and do not leak outside after the concrete is poured by 1mm, the split heads horizontal ribs are provided with grooves according to the distance between the hogging moment ribs, the depth dimension of the grooves just meets the sum of the thickness of a hogging moment rib protective layer and the diameter of the hogging moment reinforcing steel bars in the drawing design, and the hogging moment ribs are arranged in the grooves of the split heads, so that the vertical position and the horizontal position of the hogging moment ribs cannot be changed regardless of treading by personnel or disturbance of equipment. When the cast concrete floor is leveled, the trowels are used for scraping according to the height of the split heads, namely the bottom templates 1 of the thickness of the slabs are removed after the concrete reaches the stripping strength, so that the thickness of the cast-in-place slabs, the negative bending moment rib protective layers and the positions of the negative bending moment ribs can meet the requirements, and the construction is convenient.
