Description

Technical Field

[0001] The utility model belongs to a formwork support device used in the field of building construction, in particular to a formwork support rod structure for the casting of a lintel over a door opening used for a block wall. Background Art

[0002] In the prior art, the following methods are adopted for the formwork support of the lintel casting over the door opening of a block wall: ① Direct support using multiple columns. During the construction process, due to the inconsistent height dimensions of the door opening or the inconsistent length of the columns with the height of the door opening, multiple support columns need to be inclined. In addition, during the construction process, construction workers need to pass through the door opening where the lintel has not been cast yet, which seriously affects the passage and poses a safety hazard. ② Support using telescopic support rods. This support method requires that the telescopic support rods can meet the support height, but the stability is poor, multiple supports are needed, and at the same time, the support force is all concentrated on the locking structure of the telescopic support rods. Summary of the Utility Model

[0003] In order to solve the technical problems existing in the above two support structures, the utility model discloses a formwork support rod structure for the casting of a lintel over a door opening, which has a simple structure, a unified length of the support rods, and the support force acts on the wall at multiple points.

[0004] The technical solution adopted by the utility model to achieve the invention purpose is: a formwork support rod structure for the casting of a lintel over a door opening, which includes a support rod part and a group of support rod fixing parts.

[0005] The support rod part includes: a support rod and a formwork support head. The length of the support rod is less than the height of the door opening, and the formwork support head is fixed on the support rod.

[0006] The support rod fixing part includes: a locking sleeve, a sliding sleeve, and a support plate. One end of the sliding sleeve is a multi-lobe elastic sleeve with a conical outer circle. The middle part of the sliding sleeve has an external thread. The locking sleeve has a conical hole corresponding to the multi-lobe elastic sleeve and an internal thread. The locking sleeve is threadedly connected to the sliding sleeve. The support plate is fixedly connected to the other end of the sliding sleeve. The sliding sleeve is sleeved on the support rod.

[0007] The beneficial effects of the utility model are: simple structure, the support rods are designed with a unified standard length, the support force of the support rods is evenly distributed on the support rod fixing parts, and the support rods do not affect the passage of construction workers through the door opening where the lintel has not been cast yet during use. The utility model has good versatility and can be used for the formwork support of the lintel casting over the door opening of a block wall.

[0008] The following is a detailed description of the utility model with reference to the accompanying drawings. Description of the Drawings

[0013] Referring to the attached drawings, a support rod structure for a cast-in-place formwork of a door opening lintel includes a support rod part and a set of support rod fixing parts.

[0014] The support rod part includes: a support rod 1-1 and a formwork support head 1-2. The length of the support rod 1-1 is less than the height of the door opening, and the formwork support head 1-2 is fixed to the support rod (1-1).

[0015] The support rod fixing part includes: a locking sleeve 2-1, a sliding sleeve 2-2 and a support plate 2-3. One end of the sliding sleeve 2-2 is a multi-lobe elastic sleeve 2-21 with a tapered outer circle. The middle part of the sliding sleeve 2-2 has an external thread 2-22. The locking sleeve 2-1 has a tapered hole 2-11 and an internal thread 2-12 corresponding to the multi-lobe elastic sleeve 2-21. The locking sleeve 2-1 is threadedly connected to the sliding sleeve 2-2. The support plate 2-3 is fixedly connected to the other end of the sliding sleeve 2-2. The sliding sleeve 2-2 is sleeved on the support rod 1-1.

[0016] When the present utility model is in use, according to the requirements of the support strength, the number of support rod fixing parts is set on the support rod 1-1. And the interval distance of the support rod fixing parts is adjusted to ensure that each support plate 2-3 is located at the block gap position of the block wall, and the support plate 2-3 is inserted into the block gap to form the support and fixation of the support rod 1-1.

[0017] In the support rod fixing part, the sliding sleeve 2-2 can clamp and fix or loosen and move to adjust the position of the multi-lobe elastic sleeve 2-21 with respect to the support rod 1-1 through the thread.

[0018] After the support rod 1-1 is fixed by the support rod fixing part, the formwork support head 1-2 is in the formwork support position, forming the support for the formwork.

[0019] In the embodiment of the present utility model, the number of the set of support rod fixing parts is 2-5. The number of the set of support rod fixing parts is set according to the requirements of the support strength and the support stability.
