Embodiment Construction

[0014] Such as figure 1 , figure 2 , image 3 As shown, the double-wall sandwich formwork supporter of the present invention is composed of positive and negative lead screws 1, nut blocks 2, movable joints 3, support rods 4 and support plates 5. Both ends of the positive and negative lead screw 1 are designed with a wrench 6, and the corresponding two sides of the nut block 2 are provided with movable joints 3 and matched with the positive and negative lead screw 1 as a complete set. The support plate 5 is a channel steel box with two ends blocked by steel stamping, and the support rod 4 is combined with the movable joint 3 in the support plate 5 grooves through the fixed holes at both ends to form a long rectangular whole.

[0015] Such as Figure 4 As shown, the tandem rod 7 is an independent accessory with inner pulleys 8 corresponding to the pulleys 6 at both ends of the positive and negative lead screw 1.

[0016] Such as Figure 5 As shown, the wrench lever 9 is an...

Abstract

The invention provides a double-wall crack formwork support, and belongs to the field of construction equipment. The support device comprises a lead screw with left-hand thread and right-hand thread, nut blocks, movable joints, supporting rods, supporting plates, a pull block, a series-connection rod, an inner pull block, a wrenching bar and a level. The double-wall crevice template support device is characterized in that the distance of the nut blocks can be adjusted through revolving of the lead screw with left-hand thread and right-hand thread, angles of the supporting rods are changed, spaces between the supporting plates are changed, and the template can be mounted and fixed in the double-wall crack. Compared with the prior art, the double-wall crack formwork support has the advantages of small occupied area, light weight, large adjusting range, strong pressure bearing, large and smooth bearing surface, high stability, convenience and rapidness in dismantling, and low cost in single use and the like, and therefore, has good promotion and using values.

Description

1. Technical field: [0001] The invention relates to building equipment, in particular to a formwork supporter for a double-wall sandwich. 2. Background technology: [0002] With the increase of span and height of modern buildings, the setting of deformation joints is essential. Due to the narrowness of the deformation joint, it brings a lot of inconvenience and trouble to the installation and removal of the concrete structure formwork. The prior art mostly uses multiple wedges and special-shaped wedges to solve the problem, and the more advanced scissors-shaped keel support method is used. However, these methods all have problems and defects such as small adjustment range, poor stability, easy compression and deformation, and inconvenient installation and removal. 3. Contents of the invention: [0003] The object of the present invention is to solve the above deficiencies and problems, and provide a double-wall gap formwork supporter with small size, light weight, conven...
